Description

The lowering or hoisting gear that uses on the desk

Technical field

The utility model relates to the office appliance field, the lifting desk surface that especially uses on the desk.

Background technology

Along with social development, office's occupational disease is in rising trend.In a single day existing desk height all is constant, can customize height when perhaps making, still be delivered for use rear its height or very difficult change.The clerk is in for a long time on the desk desktop of sustained height and handles official business, and very easily produces the occupational disease of waist, back, neck or shank.

Summary of the invention

Goal of the invention of the present utility model is in order to overcome the problem that above-mentioned existing desk desktop can't lifting, a kind of novel structure is provided, need not to change with destroy former desktop be use on the common desk can the desk of table top height adjusting on the lowering or hoisting gear that uses.

In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:

The lowering or hoisting gear that uses on the desk comprises desktop cover board, switch, two groups of supporting components and adopts the adapter of 12V voltage that switch is installed on the desktop cover board, and desktop cover board is installed on two groups of supporting components, and two groups of supporting components are arranged in parallel; Supporting component comprises pedestal, motor, decelerator, screw mandrel, two support bars and torsion spring, motor, decelerator and screw mandrel are installed in the pedestal, decelerator links to each other with screw mandrel, motor is connected the lower end of two support bars with screw mandrel by decelerator, the middle part of two support bars is hinged by connector, and two support bars connect by torsion spring, and the upper end of support bar connects desktop cover board; Adopt the adapter of 12V voltage to link to each other with motor.

Adopted the lowering or hoisting gear that uses on the desk of technique scheme, two groups of supporting components are arranged in parallel, and have namely adopted the up-down mode of bilateral driving, have guaranteed the stationarity of lifting.Motor is connected two support bars by decelerator with screw mandrel, the too fast stability that affects lifting of toggle speed when preventing from starting.Two support bars connect by torsion spring, have solved that power of motor is too small turns round hypodynamic problem.Adopt the adapter of 12V voltage to link to each other with motor, owing to using in office, adopt adapter to increase the security of using.The advantage of the lowering or hoisting gear that uses on this desk is that novel structure is compact, and the lifting stationarity is good, and the little bearing capacity of power of motor is high, need not to change with the especially suitable office of the former desktop of destruction to use.

The specific embodiment

Below in conjunction with accompanying drawing 1 and Fig. 2 the utility model is described further.

The lowering or hoisting gear that uses on the desk as depicted in figs. 1 and 2, comprise desktop cover board 1,switch 2, two groups of supportingcomponents 3 and adopt the adapter of 12V voltage,switch 2 is installed on the desktop cover board 1, desktop cover board 1 is installed on two groups of supportingcomponents 3, two groups of supportingcomponent 3 bottoms are arranged in parallel, and are in respectively the left and right sides of desktop cover board 1 below.

Every group of supportingcomponent 3 includespedestal 31,motor 32,decelerator 33,screw mandrel 34, twosupport bars 35 and torsion spring 36.Pedestal 31 is square-tube-shaped, andmotor 32,decelerator 33 andscrew mandrel 34 are installed in thepedestal 31, andpedestal 31 volumes arelittle.Decelerator 33 links to each other withscrew mandrel 34,motor 31 is connected the lower end that connects twosupport bars 35 bydecelerator 33 with screw mandrel, the middle part of twosupport bars 35 is hinged by connector, and connector can be bolt, and twosupport bars 35 also connect bytorsion spring 36, the position oftorsion spring 36 is in the outside of connector,torsion spring 36 upper ends are fixed on the top ofsupport bar 35, andtorsion spring 36 lower ends are fixed on the bottom ofsupport bar 35, andtorsion spring 36 is two, the both sides of connector arrange respectively one, make its uniform stressed.The upper end ofsupport bar 35 connects desktop cover board 1.Decelerator 33 andscrew mandrel 34 support the use, the too fast stability that affects lifting of toggle speed when preventing from starting.Because be that office uses, therefore need the size ofcontrol pedestal 31 andmotor 32, and need the power of control motor, prevent that noise is excessive, therefore adopted the structure oftorsion spring 36, solved that power of motor is too small turns round hypodynamic problem.Adopt theadapter 6 of 12V voltage to link to each other withmotor 32, owing to using in office, adoptadapter 6 to increase the security of using, adaptor interface is on the desktop cover board 1.

The advantage of the lowering or hoisting gear that uses on the above-mentioned desk is that the lifting stationarity is good, power of motor and volume are little, bearing capacity is high, need not to change and the original desktop of destruction, especially being fit to office uses, the desktop of the use differing heights that the clerk is frequent can be regulated the state of shank, waist, back, neck and shoulder, prevents that it is in for a long time an angle and state and produces occupational disease.

Claims (1)

1. the lowering or hoisting gear that uses on the desk, the adapter that it is characterized in that comprising desktop cover board, switch, two groups of supporting components and adopt 12V voltage, switch is installed on the desktop cover board, and desktop cover board is installed on two groups of supporting components, and two groups of supporting components are arranged in parallel; Supporting component comprises pedestal, motor, decelerator, screw mandrel, two support bars and torsion spring, motor, decelerator and screw mandrel are installed in the pedestal, decelerator links to each other with screw mandrel, motor is connected the lower end of two support bars with screw mandrel by decelerator, the middle part of two support bars is hinged by connector, and two support bars connect by torsion spring, and the upper end of support bar connects desktop cover board; Adopt the adapter of 12V voltage to link to each other with motor.
