Abstract

The utility model discloses an overturning device of a liquid crystal display. The overturning device comprises a handle, the liquid crystal display and a second mounting rod, wherein the handle is arranged on the back face of the display through a first mounting rod; a meshing rod is arranged on the back face of the display and comprises a gear sheet; and a gear disc is arranged on the second mounting rod. When the overturning device is in a locking state, the gear sheet is meshed with the gear disc; and when the overturning device is in an unlocking state, the gear sheet is separated from the gear disc. Due to the meshing action between the gear sheet and the gear disc, the display can be stably kept at any position between the highest position and the lowest position and can stably and smoothly slide from one position to another position, adjustment can be conveniently and safely completed by a user through a hand, the service life of the overturning device of the liquid crystal display is greatly prolonged, and the safety of the overturning device is improved.

Description

The turning device of LCD

Technical field

The utility model relates to a kind of turning device of LCD, or rather, relates to a kind of turning device that can rest on the optional position between an extreme higher position and the extreme lower position.

Background technology

Manually the LCD TV of upset generally has three kinds of structures at present: the one, adopt the electromagnetic clutch structure, and the outside adds the control knob operation, presses the button when needing upset; Make the electromagnetic clutch energising open; And then manually upset, release button in the time of need stopping to be locked through electromagnetic clutch.Owing to be monolateral stressed, cause whole LCD torsional deformation easily, even the infringement liquid crystal display, especially when adorning large-sized liquid crystal display, and electric current is bigger during clutch operating, other working equipment in the car is prone to produce disturbs.

Second kind is that an arc chute is respectively arranged in the both sides, top, adopts finger setting, when needing upset; Two hands are pressed register pin respectively, break away from chute, when being turned to desired location then; Register pin ejects under spring action, cooperates with preset hole, plays the positioning and locking effect.Owing to need operator's both hands both sides to operate simultaneously, can make TV fall to sending out into collision suddenly with operator's head, very easily cause personal injury, and can't adjusting angle.

The third is the structure that adopts air spring, utilizes air spring to lock at two extreme positions.This installed surface is too big, has relatively high expectations in the installation site, and outward appearance is exposed various accessories, and angle also can't be regulated.

Summary of the invention

To above-mentioned defective; The purpose of the utility model is a kind of turning device of LCD; Can rest on the optional position between an extreme higher position and an extreme lower position according to user's needs; And can smoothly stably carry out the transition to another position from a position, the user can use one hand to accomplish adjusting work easily and safely.

The turning device of the LCD of the utility model comprises handle and LCD, and this handle is installed in the back side of display through first mounting rod, and a mesh rod is installed in the back side of display, and this mesh rod comprises a gear sheet.This turning device also comprises one second mounting rod, and this second mounting rod is provided with a toothed disc, and when turning device was in the lock state, the gear sheet was meshed with toothed disc, and when turning device was in released state, the described toothed disc of gear sheet was separated.This first mounting rod is installed in the back side of display through first fixture, and second mounting rod is installed in the back side of display through second fixture, and mesh rod is installed in the back side of display through the mesh rod fixture.End near handle of mesh rod is connected with first mounting rod through a rope, and the gear sheet is arranged on the other end of mesh rod.Mesh rod comprises a spring that is used for driven wheel sheet and toothed disc generation engagement.

Because the engagement of gear sheet and toothed disc; So just can make display steadily rest on the optional position between its extreme higher position and its extreme lower position; And can steadily be another position along slidingly sliding from a position; The user can use one hand to accomplish adjusting work easily and safely, has prolonged the serviceable life of LCD turning device greatly, the security that has improved turning device.

Description of drawings

Fig. 1 is the schematic perspective view of turning device of the LCD of the utility model;

Fig. 2 is the schematic perspective view that the turning device among Fig. 1 is in another visual angle, and this moment, turning device was in the lock state;

Fig. 3 is the turning device among Fig. 2, and this moment, turning device was in released state.

Embodiment

To shown in Figure 3, the turning device of LCD comprises handle 1, LCD 2 and is used to protect the shell 3 of LCD 2 like Fig. 1.This handle 1 is fixedly mounted on the back side of LCD 2 through first mounting rod 6.When the user did not stir this handle 1, handle 1 was in the position of the inside upset among Fig. 2.Owing between the handle 1 and first mounting rod 6, returning spring (not showing among Fig. 1) is installed; When the user outwards stirs this handle 1; This handle 1 can receive the effect of this returning spring; In case the user unclamps handle 1, under this handle 1 effect, will be returned to the position among Fig. 2 so at returning spring.

First mounting rod 6 is installed in the back side of LCD 2 through first fixture 15, and this first fixture 15 is fixedly connected with the back side of display 2 through screw.Also be provided with mesh rod fixture 8, one mesh rods 5 is plugged in this mesh rod fixture 8 at the back side of display 2.End 5A near handle 1 of this mesh rod 5 is connected with a rope 4, and its other end 5B comprises one and is fan-shaped gear sheet 5C, this gear sheet 5C and toothed disc 11 engagements.On this mesh rod 5, be provided with a spring 10, the back literary composition that acts on of this spring 10 can introduction.

This toothed disc 11 is arranged on second mounting rod 12, and toothed disc 11 can be integrally formed with this second mounting rod 12, also can connect through the mode of welding.This second mounting rod 12 is fixedly connected with the back side of display 2 through second fixture 14.On this second mounting rod 12, also be provided with returning spring 13.Two ends at this second mounting rod 12 also are provided with spacer 9, and this spacer 9 is fixedly connected with shell 3.

As shown in Figure 2, when the user did not contact handle 1, the gear sheet 5C and the toothed disc 11 of mesh rod 5 contacted with each other and tight engagement, and this moment, display was in the lock state.When the user stirs handle 1; As shown in Figure 3, the rope 4 of mesh rod 5 will drive mesh rod 5 and move downward, and the gear sheet 5C of mesh rod 5 separates with toothed disc 11 like this; This moment, turning device was in released state; The user unclamps handle 1 after display is turned to a suitable angle then, and mesh rod 5 meshes with toothed disc 11 under the effect of the restoring force of spring 10 again, and display just is securely fixed on this angle like this.That is to say that this spring 10 drives described gear sheet 5C and toothed disc 11 meshes.

The user can adopt the singlehanded whole adjustment process of accomplishing fully.Because the engagement of gear sheet and toothed disc; So just can make display steadily rest on the optional position between its extreme higher position and its extreme lower position; And can steadily be another position along slidingly sliding from a position; The user can use one hand to accomplish adjusting work easily and safely, has prolonged the serviceable life of LCD turning device greatly, the security that has improved turning device.
