What is the principle of the mouse automatic take up spool

The principle of achieving scalability is:: can be rolled up because the box is equipped with a spring, when pulling out the measurement length, it is actually elongated the length of the data line and the spring, once the work is completed, the spring in the box will automatically shrink, and the mouse wire will also shrink under the action of the spring force to achieve automatic take-up.

The uniqueness of the mouse telescopic cable is that its line can be retracted back into the mouse, and she has several gears, so that we can choose the length we like, reduce the trouble of winding the wire, and save space and carry it on business trips. How to use the telescopic line mouse: Pull out the telescopic line outward (pay attention to whether you buy a double-stretch or single-stretch retractable mouse), gently pull the line until the appropriate length of the sound, and then let go, you can fix the appropriate length, and then pull outward to retract the mouse.

I don't know, maybe it's the same as the vacuum cleaner, the vacuum cleaner in my house, in the case of power failure, you can automatically put the line away as soon as you press the take-up switch, I don't know what's going on.

The mouse cable take-up device is located in the inner cavity of the mouse or laptop computer, and is composed of a base, a take-up shaft wheel, a cable, a coil spring, a sliding conductive contactor, and a one-way rotation controller. The base is provided with a central connecting shaft and 4-8 brushes connected with the mouse circuit; The take-up shaft wheel is made up of a ratchet and a cylinder, the ratchet and the connecting post form a rotatable match, the 4-8 annular electrodes that are connected to the cable on it are in electrical contact with the brush, and the coil spring is fixedly connected to the connecting column and the cylinder, so the cable that is connected to the cylinder is elastically retracted, and is controlled by the one-way rotation controller, so that the cable pay-off length is kept at the best value.

The automatic take-up mechanism is to use a plurality of take-up winks, up to 4 concentric contacts, and the one-way locking of the energy storage, energy release and ratchet mechanism of the scroll spring on the surface for take-up and pay-off.

When the power cord is pulled out, the scroll spring on the surface is stored for energy, and when it stops being pulled out, the rotating shaft rotates to be locked by the ratchet mechanism under the action of the vortex spring, and the power cord stops moving; When taking up the wire, use the button or other pipes to open the locking mechanism, so that the energy storage of the scroll spring on the surface is released, and the shaft is driven to retract the power cord.

The best way is to spend two yuan to buy an ordinary box ruler, take it apart and see how it works.

There is a spring inside, you need to use some force to pull the wire, and the spring will automatically reset to retract the line when not in use.

Principle of automatic take-up: The automatic take-up mechanism is a one-way lock of the energy storage, energy release and ratchet mechanism of the vortex spring on the surface of the wind. When the power cord is pulled out, the scroll spring on the surface is stored for energy, and when it stops being pulled out, the rotating shaft rotates to be locked by the ratchet mechanism under the action of the vortex spring, and the power cord stops moving; When taking up the wire, use the button or other pipes to open the locking mechanism, so that the energy storage of the scroll spring on the surface is released, and the shaft is driven to retract the power cord.

Automatic take-up principle: there is a rewinding spring that can stretch and shrink the wire. The input terminal is connected to an external power cord, which is generally the plug part (without automatic expansion function); The power cord at the output end can be connected to the socket, power strip, or directly to the equipment.

There is a self-locking device in the reel, there is an automatic wire arrangement, after pulling out a section of the cable, the self-locking device works (the power cord stops moving), if you want the wire to retract, you need to pull out a section of the power cord again, the wire passes through the self-locking device to loosen the power cord, and the wire is automatically retracted. The wire is free to retract, convenient and practical, effectively ensuring the neatness and beauty of electrical appliances, avoiding the chaos of the power cord, and stretching it as long as you want.

We have 100 high-efficiency greenhouses, the curtain machine is retractable up and down, and the cable cannot be retracted, can it be solved?

The maintenance plant that does not use the winder is dangerous for the energy pipeline, the pipeline that was dragged anywhere in the past is very susceptible to corrosive material damage, and at the same time, the worker's unintentional stepping on the pipeline accelerates the scrapping of the pipeline, and through the timely contraction of the winder, the above dangers can be avoided and the service life of the tool can be extended. The service life of the tool is extended, the operating cost is reduced, and the Xusheng winder is really a good housekeeper.

The portable kind.

The line is not easy to use, and it is quite thin.

It's three turns, and then one buckle.

I don't know how you dismantled it.

Adjust the sensitivity in the vertical and horizontal directions, such as y-axis 1 and x-axis 10, so that the mouse can move ten times the distance in the vertical direction to walk horizontally on the screen for the same distance.

As for what it is used for, most of them are used for drawing or design software. There are also individual games that can be used, such as the CF Carrier 45 degree gun, which can be adjusted to the mouse can only pan and not move up and down.

It's the built-in telescopic cable that rolls the mouse cable in it.

It's a coil of thread.

There are springs in it.

It can automatically rotate back when not in use.

Same as roll paper.

I don't know if you've ever pulled those curtains. It's a bit like that. He has an automatic shrinkage roll in it. You pull it and it pulls out. But as long as you don't let go, one of the card slots inside him won't get stuck in.

The contraction line mouse has an axis.

Usually one is stretched out.

Then press a small boot on the top of the shaft housing, and shrink back at one point.

The mouse telescopic cable is stretched once and then retracted.

You try it.

After using the retractor many times, the elasticity of the retractor deteriorates, and it is normal for you to have such a problem.

The working principle of BAI is as follows:

du1, the photoelectric mouse has a light-emitting diode inside, DAO through the light line it emits, can illuminate the bottom surface of the electric mouse (this is the reason why the bottom of the mouse will always glow).

2. A part of the light reflected back by the bottom surface of the photoelectric mouse is transmitted to an optical sensing device (micro-imager) for imaging after passing through a set of optical lenses.

3. When the photoelectric mouse moves, its movement trajectory will be recorded as a set of coherent images taken at high speed, which will be analyzed and processed by a special image analysis chip (DSP, that is, digital microprocessor) inside the photoelectric mouse. The chip analyzes the changes in the position of the feature points on these images to determine the direction and distance of the mouse, so as to complete the positioning of the cursor.

The working principle of the mouse: The mouse can be divided into machine according to the different working principles

Mechanical mouse and light.

DAO electric mouse. Machine.

The main purpose of the mechanical mouse is composed of a rolling ball, a roller column and a grating signal sensor. When you drag the mouse, the ball rotates, and the ball drives the roller column to rotate, and the photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller column reflects the mouse.

The displacement of the scaler changes in the vertical and horizontal directions, and then the cursor on the screen is controlled by the processing and conversion of the computer program.

The movement of the arrows. The photoelectric mouse is to detect the displacement of the mouse, convert the displacement signal into an electrical pulse signal, and then control the movement of the cursor arrow on the screen through the processing and conversion of the program. Photoelectric mouse with photoelectric sensor generation.

Substitute for the ball. These sensors require a special backing plate with a striped or dotted pattern.
