Description

Technical Field

[0002] A liquid crystal splicing screen is a large-size flat display device, usually composed of multiple liquid crystal display modules, which form a large-screen display surface through combination. Multiple liquid crystal screens are connected through connectors. However, in some existing connection structures, the liquid crystal screens are connected to the side edges of each other. Since the relatively large liquid crystal screens are heavy, during installation, the installer needs to hold the liquid crystal screen while fixing it. If the installation position of the liquid crystal screen is relatively high, it will increase the installation difficulty and safety hazards. Moreover, some existing connectors cannot adjust the distance between multiple liquid crystal screens, resulting in inconvenient installation.

[0003] Therefore, it is necessary to design a connection structure of a liquid crystal splicing screen to overcome the above technical defects. Summary of the Invention

Specific Embodiment

[0021] This specific embodiment is a connection structure of a liquid crystal splicing screen, and its structural schematic diagram is as Figures 1-4 shown, including a mounting bracket 1 and a main body of liquid crystal screen 2. There are several mounting brackets 1, and the front wall of the mounting bracket 1 is not enclosed. The main body of liquid crystal screen 2 is assembled on the rear side wall of the mounting bracket 1. The inner rear side wall of the mounting bracket 1 is symmetrically and movably connected with gears 3. Between the two gears 3, a fixing plate 4 is symmetrically arranged. The fixing plate 4 is movably connected with the inner rear side wall of the mounting bracket 1. On the side of the fixing plate 4 opposite to the gear 3, uniformly distributed tooth blocks 18 are fixedly connected. The tooth blocks 18 are meshed with the gears 3. A fixing mechanism is arranged on the inner rear wall of the mounting bracket 1, and the fixing mechanism is movably connected with the fixing plate 4. On the inner rear side wall of the mounting bracket 1 near the right side, a connecting mechanism is symmetrically arranged.

[0022] When splicing multiple main bodies of liquid crystal screens 2, it is necessary to first fix one of the mounting brackets 1 at the place where it needs to be used through a relatively mature technology in the prior art. The fixing method can be selected according to actual use. When multiple main bodies of liquid crystal screens 2 need to be spliced and used, another mounting bracket is successively spliced with the already fixed mounting bracket 1.

[0023] As Figures 1-3 shown, the fixing mechanism includes a mounting plate 7. The mounting plate 7 is slidably connected with the inner rear side wall of the mounting bracket 1. On the front wall of the mounting plate 7 near the left side, pull rods 6 are symmetrically and movably connected. The rear side walls of the two pull rods 6 are respectively movably connected with the fixing plate 4. The right side wall of the mounting plate 7 is movably connected with a screw rod 8. The inner rear side wall of the mounting bracket 1 is fixedly connected with a rectangular plate 9. One side of the rectangular plate 9 is provided with a screw hole 10. One end of the screw rod 8 passes through the screw hole 10 and extends to the right side of the rectangular plate 9 and is fixedly connected with a knob 11.

[0024] Among them, the knob 11 can actually replace the hexagonal nut as needed, so that the screw rod 8 can be rotated by a tool wrench, which plays a role in saving effort.

[0025] As Figure 1 and Figure 4As shown in the figure, the connecting mechanism includes U-shaped plates 14. There are two U-shaped plates 14, which are respectively fixed on the inner wall of the rear side of the mounting bracket 1. A rack 13 is arranged inside the U-shaped plate 14. Rectangular openings 12 are symmetrically formed on the left and right sides of the mounting bracket 1 respectively. One end of the rack 13 extends into the mounting bracket 1, and the other end passes through the rectangular opening 12 and extends to the outside of the mounting bracket 1. A threaded hole 15 is formed on the front wall of the U-shaped plate 14, and a bolt 16 is installed in the threaded hole 15. One end of the bolt 16 extends into the U-shaped plate 14 and contacts the rack 13.

[0026] The size of the rectangular opening 12 is matched with that of the rack 13. In actual use, this can prevent the mounting bracket 1 from shaking.

[0027] Among them, limiting wheels 5 are respectively movably connected to the inner wall of the rear side of the mounting bracket 1 near the top and bottom. Through the limiting wheels 5, the stability of the two mounting brackets 1 can be increased, and the shaking between the two mounting brackets 1 can be avoided.

[0028] In addition, cylindrical blocks 17 are symmetrically arranged between the two fixing plates 4. The cylindrical blocks 17 are fixedly connected to the inner wall of the rear side of the mounting bracket 1. The angle of inward swing of the fixing plate 4 can be limited by the two cylindrical blocks 17, so that each time the fixing plate 4 is pushed, the fixing plate 4 will always be in an inclined state, which can avoid jamming and improve the stability of use.

[0029] Among them, one end of the rack 13 is arc-shaped. With the rack 13 having an arc-shaped end, the rack 13 can be more easily inserted between the limiting wheel 5 and the gear 3.

[0030] Working principle: When this technical solution is in use, first, a mounting frame 1 is fixed at the place where it is needed. The fixing method can be achieved through existing and relatively mature technologies. Next, if multiple LCD panel bodies 2 need to be spliced and used, first, the LCD panel bodies 2 are assembled on the mounting frame 1. Then, the screw 8 is rotated in the reverse direction by the knob 11, so that the mounting plate 7 moves to the right. Synchronously, the fixing plate 4 is pulled by the pull rod 6 through the mounting plate 7 to swing towards the middle, so that the tooth block 18 is disengaged from the gear 3. Next, the two racks 13 on the mounting frame 1 are inserted into the rectangular opening 12 on the already fixed mounting frame 1, and the rectangular opening 12 is engaged with the gear 3, so that the gear 3 rotates. At this time, the distance between the two LCD panel bodies 2 can be selected according to actual needs, which can be achieved by the depth of inserting the rack 13. After the adjustment is completed, the screw 8 is rotated in the forward direction by the knob 11. The screw 8 drives the mounting plate 7 to move to the left, so that the pull rod 6 pushes the two fixing plates 4 to swing outwards, achieving the effect that the tooth block 18 is engaged with the gear 3. In this way, the position of the rack 13 can be fixed, so that the positions of multiple mounting frames 1 can be fixed, achieving the purpose of installation. After installing multiple mounting frames 1, the rightmost rack 13 is retracted into the mounting frame 1 to improve the aesthetics. First, loosen the bolt 16, then retract the rack 13 into the mounting frame 1, and then tighten the bolt 16, achieving the effect of fixing the rack 13 and preventing the rack 13 from sliding, which can effectively improve the convenience of installation.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
