Abstract
The utility model provides a lifting device for a computer screen, wherein, a support body is provided with an arc rail with up and down trend; a lifting trolley is pushed by a drive device to move up and down along the arc rail, and the computer screen is fixed on the lifting trolley. The device can simultaneously ensure that the screen is faced to a user at a best angle when the height of the screen is adjusted, so that the cervical vertebra of the user can be in a slightly moving state, thereby playing a role in protecting the cervical vertebra and relieving fatigue.
Description
(1) technical field:
The utility model is a kind of computer screen jacking gear, is used for adjusting the height and the angle of computer screen.
(2) background technology:
Existing " the special-purpose lifter of a kind of liquid crystal screen " technology (patent No. 02282796.x), screen is installed on the lifter, can move up and down to be hidden into below the desktop.Because this technology problem to be solved is a screen-concealing,, can not adjust angle so adopt rectilinear motion mode.
(3) summary of the invention:
Problem to be solved in the utility model be allow the user utilize easily manual or electronic mode adjust the height of computer screen and make its all the time with best angle in the face of the user; user's its cervical vertebra when watching screen is in different angles or light activity state, the effect of playing the protection cervical vertebra and lessening fatigue.
The technical solution of the utility model is:
Two tracks of trend are up and down arranged on the support body of jacking gear, lift cart moves up and down at the promotion lower edge of drive unit track, drive unit is installed on the support body or on the lift cart, computer screen is fixed on the lift cart, Zou Xiang track is an arc track up and down, like this, lift cart is under the promotion of drive unit during along the orbital motion of trend up and down, and computer screen all the time can be with best angle in the face of the user.
Concrete scheme one adopts manual mode, and drum wheels is equipped with in the support body upper end, and the rope band of circumvolution or chain one end are hung and be hung on lift cart or the screen it on, the other end with the heavy phase extension is hung, make screen be in correct position by manual adjustments.
Concrete scheme two is to adopt motor reducer to drive drum wheels on the basis of such scheme, moves up and down thereby drive lift cart.
Concrete scheme three is that motor reducer is installed on the lift cart, and its gear of output end is meshed with tooth bar on the arc track, during the motor rotation, just can drive lift cart and move up and down along arc track.
Will have correspondent control circuits to match when adopting electronic mode, its circuit and simple principle of work are seen description of drawings.
The beneficial effects of the utility model are: lift cart can be parked in the different parts of arc track or move up and down along it; the computer screen that is fixed on the lift cart can be with best angle in the face of the user; the user is when watching screen; its cervical vertebra is in different angles or is in the light activity state, the effect of playing the protection cervical vertebra and lessening fatigue.
(4) description of drawings:
Accompanying drawing 1 is for adopting the screen jacking gear of concrete scheme one.
Accompanying drawing 2 is for adopting the screen jacking gear of concrete scheme three.
In the accompanying drawing 1,2,1 support body, 2 arc tracks, 3 lift carts, 4 LCD screen, 5 drum wheels, 6 rope bands, 7 counterweights, 8 counterweight tracks, 9 arc track tooth bars, 10 motor reducers, 11 speed reduction unit gear of output end.
Accompanying drawing 3 control circuit when adopting electronic mode.
In the accompanying drawing 3,12 direct current motors, 13,14 interlock limit switch contacts (limit switch is installed on the lift cart), 15,16 diodes, 17 transformers, 18 switches, 19 attaching plugs, a, b are the transformer alternating output terminal.
The simple operation principle of control circuit: after switch 18 closures, the electric current road The footpath be a-16-13-12-b, lift cart decline, spacing opening after the limit The pass is bumped, and 13 disconnect 14 closures, and current path is b-12-15-14-a, The motor counter-rotating, lift cart rises and automatically pumps.
(5) embodiment:
Adopt concrete scheme three.
With reference to accompanying drawing 2: two arc tracks 2 of trend are up and down arranged on the support body 1, motor reducer 10 is installed on the lift cart 3, its gear of output end 11 is meshed with tooth bar 9 on the arc track 2, lift cart 3 moves up and down at the promotion lower edge of motor reducer 10 arc track 2, and computer screen 4 is fixed on the lift cart 3.
Circuit is as shown in Figure 3: 12 direct current motors, and 13,14 interlocks are limited to switch contact, 15,16 diodes, 17 transformers, 18 switches, 19 attaching plugs, a, b are the transformer alternating output terminal.
Claims (1)
1. computer screen jacking gear, two tracks of trend are up and down arranged on the support body of described jacking gear, lift cart moves up and down at the described track in the promotion lower edge of drive unit, described drive unit is installed on the described support body or on the described lift cart, computer screen is fixed on the described lift cart,, it is characterized in that the described track of trend up and down is an arc track.
