Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display assembly technology, and in particular to an auxiliary tooling for assembling the outer frame of a liquid crystal display. Background Technology

[0002] In actual production, LCD screens need to be assembled, which involves assembling the back cover and outer frame of the LCD screen so that the LCD screen is supported and protected by the outer casing.

[0003] A search revealed that patent document CN111590301B discloses an auxiliary tooling for assembling the outer frame of a computer LCD screen. The tooling includes a bottom support plate, a side support rib that stands upright at the top of the bottom support plate, a horizontally fixed top support plate at the top of the side support rib, a pneumatic cylinder fixedly mounted at the top of the top support plate, a piston rod extending downwards from the pneumatic cylinder, and a square-shaped clamping block at the bottom of the piston rod with a protruding clamping pad at the bottom. Support columns ensure that the bottoms of the two clamping frames are horizontally fixed. The protruding locking blocks at the top of the two clamping frames clamp the sides of the screen with the back cover, thus fixing the screen with the back cover onto the two clamping frames and improving the clamping stability of the screen with the back cover.

[0004] Based on the above search and combined with existing technology, it was found that the existing auxiliary tooling for assembling the outer frame of an LCD display is suitable for the final outer frame installation after the back cover and screen are assembled. However, in actual work, before installing the screen, it is also necessary to assemble the frame on the back cover so that the back cover can accommodate the screen panel. In this process, the frame on the four sides needs to be snapped and pre-fixed. After confirming that the installation position is accurate, bolts are used to fix it. The existing pre-fixing method generally uses the initial screwing in of some bolts to achieve the pre-fixing effect, but it is not easy to adjust after screwing in, and there are no corresponding tools to achieve the auxiliary effect of easy pre-fixing. Therefore, an auxiliary tooling for assembling the outer frame of an LCD display is needed. Utility Model Content

[0005] The purpose of this application is to provide an auxiliary tooling for assembling the outer frame of a liquid crystal display screen to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an auxiliary tooling for assembling the outer frame of a liquid crystal display screen, comprising two symmetrically arranged clamps, one above the other, with a rubber plate fixed to one side of each clamp that is close to the other. An operating handle is installed on one side of both clamps. The operating handle includes a first Z-shaped handle, a second Z-shaped handle, and a tension spring. One end of the first Z-shaped handle is fixed to one side of the lower clamp, and one end of the second Z-shaped handle is fixed to one side of the upper clamp. The first Z-shaped handle and the second Z-shaped handle are slidably connected. The parallel horizontal plates of the first Z-shaped handle and the second Z-shaped handle are elastically connected by a tension spring. The clamps and operating handle are each provided in two sets. The two sets of clamps are arranged horizontally and are connected by an adjustable rod. The connecting rod can also adjust the angle between the two clamps.

[0007] As a further supplement to this solution, a second sliding groove is provided in the middle of the first Z-shaped handle, and a sliding folding plate is formed in the middle of the second Z-shaped handle to slide and adapt to the second sliding groove. The vertical plate of the first Z-shaped handle and the vertical plate of the second Z-shaped handle slide in contact, and the sliding folding plate slides vertically along the second sliding groove.

[0008] As a further supplement to this solution, both sets of clamps are provided with first sliding grooves. The inner diameter of the opening of the two first sliding grooves is smaller than the inner diameter of the first sliding groove and the openings are arranged opposite to each other. The two ends of the connecting rod are respectively slidably inserted into the two first sliding grooves, and the two ends of the connecting rod are fixed with limit blocks.

[0009] As a further supplement to this solution, the connecting rod includes a first slide rod and a second slide rod, with the ends of the first slide rod and the second slide rod close to each other being rotatably connected; The first slide bar and the second slide bar are fixed together by locking bolts.

[0010] As a further supplement to this solution, a female head is formed at the end of the first slide rod near the second slide rod, and a male head is formed at the end of the second slide rod near the first slide rod. The male head is rotatably inserted into the female head. Both the female head and the male head have through holes for the locking bolt to pass through. A nut is screwed to the lower end of the locking bolt. The nut of the locking bolt and the nut cooperate to clamp the female head, so that the female head and the male head are fixed by friction.

[0011] As a further supplement to this solution, the axis of the locking bolt is set vertically, and the first slide rod and the second slide rod rotate horizontally relative to each other along the axis of the locking bolt.

In this utility model, the two clamping plates, the first Z-shaped handle, the second Z-shaped handle and the tension spring work together to clamp the frame well and achieve the pre-fixing effect; at the same time, the two sets of clamping plates and the operating handle can also adjust the distance and angle, so that different positions of the frame or the close parts of two adjacent frames can be clamped at the same time, and the pre-fixing effect is better.

[0013] 2. In this utility model, by pulling the two sets of clamping plates, the clamping plates can slide relative to each other along the first slide rod or the second slide rod, thereby adjusting the distance between the two sets of clamping plates; or by loosening the locking bolt, the frictional fixing relationship between the female head and the male head is released, thereby allowing the two sets of clamping plates to rotate and the first slide rod and the second slide rod to form the required angle.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figures 1-4 The auxiliary tooling for assembling the outer frame of a liquid crystal display screen shown includes two symmetrically arranged clamping plates 1, and a rubber plate 3 is fixed on the side of the two clamping plates 1 that is close to each other. An operating handle 2 is installed on one side of both clamping plates 1. The operating handle 2 includes a first Z-shaped handle 21, a second Z-shaped handle 22 and a tension spring 23. One end of the first Z-shaped handle 21 is fixed to one side of the lower clamping plate 1, and one end of the second Z-shaped handle 22 is fixed to one side of the upper clamping plate 1. The first Z-shaped handle 21 and the second Z-shaped handle 22 are slidably connected. The parallel horizontal plates of the first Z-shaped handle 21 and the second Z-shaped handle 22 are elastically connected by the tension spring 23. Both the clamping plate 1 and the operating handle 2 are provided in two sets. The two sets of clamping plates 1 are arranged horizontally, and the two sets of clamping plates 1 are connected by an adjustable distance through a connecting rod 4. The connecting rod 4 can also adjust the included angle between the two clamping plates 1.

[0019] Based on the above structure, when assembling the frame of the back shell, the worker only needs to insert the frame into the back shell and then press the first Z-shaped handle 21 and the second Z-shaped handle 22 relative to each other, so that the two second Z-shaped handles 22 are close to each other, which can overcome the elastic force of the tension spring 23 and drive the two clamping plates 1 away from each other. Then, place the two clamping plates 1 on the upper and lower sides of the back shell and the frame, and release the first Z-shaped handle 21 and the second Z-shaped handle 22. The two clamping plates 1 will then be close to each other under the elastic force of the tension spring 23, so that the rubber plate 3 will contact the back shell and the frame under the action of the two clamping plates 1, which will play a good clamping role on the frame and achieve the pre-fixing effect. Meanwhile, the two sets of clamps 1 and the operating handle 2 can also adjust the distance and angle, so that different positions of the frame or the close parts of two adjacent frames can be clamped at the same time, resulting in a better pre-fixing effect.

[0020] Furthermore, a second sliding groove 211 is provided in the middle of the first Z-shaped handle 21, and a sliding folding plate 221 is formed in the middle of the second Z-shaped handle 22 to slide and adapt to the second sliding groove 211. The vertical plate of the first Z-shaped handle 21 and the vertical plate of the second Z-shaped handle 22 slide vertically along the second sliding groove 211.

[0021] Furthermore, both sets of clamping plates 1 are provided with first sliding grooves 11. The inner diameter of the opening of the two first sliding grooves 11 is smaller than the inner diameter of the first sliding groove 11 and the openings are arranged opposite to each other. The two ends of the connecting rod 4 are respectively slidably inserted into the two first sliding grooves 11. Both ends of the connecting rod 4 are fixed with limit blocks 43. The connecting rod 4 includes a first slide rod 41 and a second slide rod 42, with their ends rotatably connected. The first slide rod 41 and the second slide rod 42 are fixed together by a locking bolt 5. Specifically: The first slide rod 41 has a female head 411 at the end near the second slide rod 42, and the second slide rod 42 has a male head 421 at the end near the first slide rod 41. The male head 421 is rotatably inserted into the female head 411. Both the female head 411 and the male head 421 have through holes for the locking bolt 5 to pass through. The lower end of the locking bolt 5 is screwed with a nut 51. The nut of the locking bolt 5 and the nut 51 cooperate to clamp the female head 411, so that the female head 411 and the male head 421 are fixed by friction. The locking bolt 5 is vertically oriented, and the first slide rod 41 and the second slide rod 42 rotate horizontally relative to each other along the axis of the locking bolt 5.

[0022] If it is necessary to adjust the distance or angle between the two sets of clamping plates 1, the user only needs to pull the two sets of clamping plates 1 to make the clamping plates 1 slide relative to each other along the first slide bar 41 or the second slide bar 42, thereby adjusting the distance between the two sets of clamping plates 1; or loosen the locking bolt 5 to release the frictional fixing relationship between the female head 411 and the male head 421, thereby allowing the two sets of clamping plates 1 to rotate and make the first slide bar 41 and the second slide bar 42 form the required angle, and then tighten the locking bolt 5 to complete the adjustment of the angle of the two sets of clamping plates 1.

[0023] It should be noted that although no fixing structure is set after the spacing of the two sets of clamps 1 is adjusted, the two sets of clamps 1 are clamped and fixed to the back shell and the frame when in use. Therefore, the relative distance between the two sets of clamps 1 is not easy to move, and it can still play a stable pre-fixing effect. Thus, there is no need to fix the two sets of clamps 1 to maintain a fixed spacing, and the use is relatively more flexible and convenient.

[0024] The working principle of this utility model is as follows: In daily use, when assembling the frame of the back shell, the operator only needs to insert the frame into the back shell and then press the first Z-shaped handle 21 and the second Z-shaped handle 22 relative to each other, so that the two second Z-shaped handles 22 are close to each other, which can overcome the elastic force of the tension spring 23 and drive the two clamping plates 1 away from each other. Then, the two clamping plates 1 are placed on the upper and lower sides of the back shell and the frame, and the first Z-shaped handle 21 and the second Z-shaped handle 22 are released, so that the two clamping plates 1 are close to each other under the elastic force of the tension spring 23, so that the rubber plate 3 contacts the back shell and the frame under the action of the two clamping plates 1, which plays a good clamping role on the frame and achieves the pre-fixing effect. Meanwhile, the two sets of clamping plates 1 and the operating handle 2 can also adjust the distance and angle. Specifically, the user only needs to pull the two sets of clamping plates 1 to make the clamping plates 1 slide relative to each other along the first slide bar 41 or the second slide bar 42, thereby adjusting the distance between the two sets of clamping plates 1; or loosen the locking bolt 5 to release the frictional fixing relationship between the female head 411 and the male head 421, thereby allowing the two sets of clamping plates 1 to rotate and make the first slide bar 41 and the second slide bar 42 form the required angle. Then tighten the locking bolt 5 to complete the adjustment of the angle of the two sets of clamping plates 1, thereby enabling simultaneous clamping of different positions of the frame or close areas of two adjacent frames, resulting in a better pre-fixing effect. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
