Description
Technical field
The utility model relates to a kind of base for liquid crystal display, specifically a kind of LCD electric lifting pedestal.
Background technique
On market, existing LCD elevating base only has hand-operated lifting.Along with display sizes is increasing, simultaneously touch screen etc. causes display device also more and more heavier adding of function.Existing hand-operated lifting base all seems more and more inconvenient in actual use.And the electric lifting/lowering base of existing patent aspect mostly is the complicated technological scheme being difficult to realize, cannot carry out spacing to lift path.
Model utility content
For the deficiencies in the prior art, the invention provides a kind of simple operation, structure is simply easy to the electric lifting/lowering chassis technology scheme of realization simultaneously.
The technological scheme that the present invention is adopted for achieving the above object is: a kind of LCD electric lifting pedestal, comprise key control panel 9 and connect stepper motor 2, control step motor 2, screw rod 3 connects described stepper motor 2, nut 5 is driven to carry out elevating movement, positioning limiting fixator 4 is connected with nut 5 bolt, and restriction nut 5 horizontally rotates; Described positioning limiting fixator 4 two ends arrange column structure, are placed in the guiding groove of rail brackets 6 both sides, coordinate limit lift path with guiding groove; Described stepper motor 2 is fixed on guide rail lower end by lower fixed block 8, and described lower fixed block 8 is connected with rail brackets 6 bolt; Described positioning limiting fixator 4 is connected with display device link 1 bolt, drives the elevating movement of display device link 1.
Also comprise chassis 10 for fixed guide support 6.
Also comprise that button 11 is corresponding with key control panel 9 to be arranged and be placed on chassis 10, key control panel 9 is controlled.
Also comprise decorative shell 7 and be placed in chassis 10 draw-in groove.
The present invention has following beneficial effect and advantage:
1. utilize stepper motor only just can rotate providing drive singal, and the feature of accurate positioning, accurately control the Distance geometry speed that screw rod screws in and screws out in nut.
2. the column structure of positioning limiting fixator interts in the guiding groove of rail brackets, can only move up and down.Positioning limiting fixator and nut are fixed, and the restriction that nut is subject to positioning limiting fixator does oscilaltion campaign with it.Thus make the rotation of stepper motor become elevating movement.
3. rail brackets is by its guiding groove restriction positioning limiting fixator moving direction, and fix with lower fixed block, lower fixed block and stepper motor are fixed, thus stepper motor is fixed on below the inner guiding groove of rail brackets.Fix with chassis and the elevator mechanism of the whole series is erected, coordinate with decorative shell, play beautification function.
Accompanying drawing explanation
Fig. 1 is Standard figure of the present utility model;
Fig. 2 is overall appearance figure of the present utility model;
Wherein, 1 be display device link, 2 be stepper motor, 3 be screw rod, 4 be positioning limiting fixator, 5 be nut, 6 be rail brackets, 7 be decorative shell, 8 be lower fixed block, 9 be key control panel, 10 be chassis, 11 for button.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Be illustrated in figure 1 structural drawing of the present utility model.Exerted a force by the button 11 on chassis 10 and arrive key control panel 9, key control panel 9 switches on power, control step motor 2 forward or reverse, and drive screw rod 3 forward or reverse, screw rod 3 screws in or screws out in nut 5.Because nut 5 is limited rotation by positioning limiting fixator 4 by rail brackets 6, nut 5 and positioning limiting fixator 4 simultaneously, positioning limiting fixator 4 and display device link 1, display device link 1 and display device are all fixed together, the oscilaltion of final drive display device.
From the structure of product, form primarily of display device link 1, stepper motor 2, screw rod 3, nut 5, positioning limiting fixator 4, lower fixed block 8, rail brackets 6, key control panel 9, chassis 10, button 11, decorative shell 7.
1) display device link 1: connect display device by international VESA hole.
2) stepper motor 2: can forward or reverse, drives screw rod 3 forward or reverse.
3) screw rod 3: under driving stepper motor, can screw in or screw out in nut 5, drives nut 5 to move.
4) positioning limiting fixator 4: be fixed together with nut 5 and display device link 1, coordinates with rail brackets 6 and prevents nut 5 from rotating.
5) nut 5: under screw rod 3 turning effort, move up and down.
6) rail brackets 6: lower end is fixed on chassis 10, guides positioning limiting fixator and nut, display device link to move up and down simultaneously.
7) decorative shell 7: decorative base, on the basis ensureing internal structure, can be designed to different appearance.
8) fixed block 8 under: fixing stepper motor.
9) key control panel 9: power supply inputs, control step motor, makes stepper motor forward or reverse simultaneously.
10) chassis 10: fixed guide support, decorative shell, button and key control panel.
11) button 11: by key operation key control panel, controls base lifting.
Working procedure is: by control step motor 2 forward and reverse, and drive screw 3 screws in and screws out in nut 5.Positioning limiting fixator 4 is fixed with nut 5 and display device link 1, is interted the rotation preventing nut 5 in rail brackets 6 guiding groove by positioning limiting fixator 4 column structure, makes nut 5 drive positioning limiting fixator 4 and display device link 1 to move up and down.Display device link 1 is connected with liquid crystal display, thus drives liquid crystal display to move up and down.
