Description

Technical Field

[0001] The utility model relates to the technical field of splicing structures, in particular to a splicing structure of a vehicle-mounted LCD liquid crystal display screen. Background Art

[0002] LCD is a display that uses liquid crystal as material. Liquid crystal is a type of organic compound between solid and liquid. At room temperature, it exhibits both the fluidity of liquid and the optical anisotropy of crystal. It becomes a transparent liquid when heated and a crystalline turbid solid when cooled. During performances or large-scale events, multiple LCD screens are usually assembled and used for convenience.

[0003] The existing splicing mechanism cannot adjust the internal width according to the thickness of the display screen, which leads to the problem of a narrow range of structural use. A splicing structure of a vehicle-mounted LCD display screen is now proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a splicing structure of a vehicle-mounted LCD liquid crystal display screen to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A splicing structure of a vehicle-mounted LCD liquid crystal display screen comprises an adjusting mechanism, one side of the adjusting mechanism is hinged with a supporting mechanism, and the left side of the supporting mechanism is fixedly connected with a fixing mechanism.

[0007] The adjusting mechanism comprises an electric push rod, a retracted end of the electric push rod is fixedly connected with a push plate, the push plate is fixedly connected with a support rod symmetrically on the left and right sides, and a front side of the push plate is fixedly connected with an anti-slip pad.

[0008] A further improvement of the technical solution of the utility model is that: the four corners of the push plate are hinged with an adjusting ball 1, the surface of the adjusting ball 1 is hinged with a connecting rod, one end of the connecting rod is hinged with an adjusting ball 2, and the connecting rod rotates on the adjusting ball 1 and the adjusting ball 2, thereby adjusting the angle of the connecting rod and then supporting the four corners of the push plate.

[0009] A further improvement of the technical solution of the utility model is that the supporting mechanism includes a supporting frame, the rear side of the supporting frame is sleeved on the outside of the electric push rod and the push plate, the right side of the supporting frame is fixedly connected to a limiting plate, and the limiting plate fixes the right side position of the display screen, thereby ensuring the stability of the display screen.

[0010] A further improvement of the technical solution of the utility model is that: a heat dissipation hole is opened on the surface of the limit plate, a connecting frame is fixedly connected to the back of the support frame, and the connecting frame is fixedly connected to the tail end of the electric push rod. The heat generated when the display screen is running can be discharged through the heat dissipation hole, thereby improving the heat dissipation strength of the display screen.

[0011] A further improvement of the technical solution of the utility model is that: the support frame is symmetrically provided with fixing grooves on the upper and lower parts, the upper and lower surfaces of the support frame are provided with sliding grooves, and the upper and lower parts of the support frame are provided with threaded holes. The fixing grooves and the limiting grooves both serve to limit the position of the extrusion plate, thereby making the structure more stable.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a splicing structure of a vehicle-mounted LCD liquid crystal display screen. When the electric push rod is started, the push plate and the support rod are driven to move forward and backward. When the push plate moves, the four corners of the push plate are supported by the cooperation of the connecting rod, the first adjusting ball and the second adjusting ball.

The extrusion plate and the spring are pressed to the left, and then the display screens to be spliced ​​are placed in the support frame from right to left in sequence. After the placement is completed, the extrusion plate is released, and the pressure on the spring disappears, thereby driving the extrusion plate to move to the right, so that the extrusion plate is attached to the left side of the display screen, and then the fixing bolts are screwed into the mounting plate and the threaded hole to further fix the extrusion plate, so that the spliced ​​display screens of different lengths can be fixed, thereby achieving the purpose of improving the practicality of the splicing mechanism.

[0025] Specifically, the electric push rod 11 is started to drive the push plate 12 to move forward and backward, thereby driving the adjusting ball 14 to rotate between the push plate 12 and the connecting rod 15, and the adjusting ball 2 16 to rotate between the connecting rod 15 and the support frame 21. When the push plate 12 moves, the connecting rod 15, the adjusting ball 14 and the adjusting ball 2 cooperate with each other, thereby supporting the four corners of the push plate 12. The anti-skid pad 17 moves with the push plate 12, thereby increasing the friction with the back of the LCD screen. At the same time, the support rod 13 increases the supporting strength of the rear side of the anti-skid pad 17, thereby enhancing the fixing strength of the LCD screen. Therefore, the position of the push plate 12 and the anti-skid pad 17 can be adjusted according to the thickness of the spliced ​​LCD screen, so that LCD screens of different thicknesses can be fixed, thereby expanding the application range of the structure.

The right side of the spliced ​​screen is attached to the limit plate 22. The heat generated during operation can be discharged through the heat dissipation holes 23, thereby improving the heat dissipation strength of the screen.

[0030] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixing mechanism 3 includes a fixing plate 31, a spring 32 is fixedly connected to the left side of the fixing plate 31, the spring 32 is located inside the fixing groove 25, the right end of the spring 32 is fixedly connected to the extrusion plate 33, the upper and lower parts of the extrusion plate 33 are fixedly connected to the mounting plate 34, the internal thread of the mounting plate 34 is connected to the fixing bolt 35, the tail end of the fixing bolt 35 is threadedly connected to the inside of the threaded hole 27, the extrusion plate 33 is slidably connected to the inside of the support frame 21, and is slidably connected to the inside of the slide groove 26;

[0031] Specifically, the extrusion plate 33 and the spring 32 are pressed to the left, and then the display screens to be spliced ​​are placed in the support frame 21 from right to left. After the placement is completed, the extrusion plate 33 is released, and the pressure on the spring 32 disappears, thereby driving the extrusion plate 33 to move to the right, so that the extrusion plate 33 is in contact with the left side of the display screen, and then the fixing bolt 35 is screwed into the mounting plate 34 and the threaded hole 27 to further fix the position of the extrusion plate 33 and the display screen, so that spliced ​​display screens of different lengths can be fixed. The extrusion plate 33 is narrow, so as to avoid affecting the movement range of the push plate 12, the support rod 13 and the anti-slip pad 17.

[0032] The following is a detailed description of the working principle of the splicing structure of the vehicle-mounted LCD display.

[0033] like Figure 1-4 As shown, the squeezing plate 33 and the spring 32 are pressed to the left, and then the display screen to be spliced ​​is put in from the right side of the support frame 21 in sequence, so that the rightmost display screen is in contact with the limit plate 22, and the position of the right side of the display screen is fixed. After putting it in, the electric push rod 11 is started to drive the push plate 12 to move back and forth, thereby driving the adjusting ball 14 to rotate between the push plate 12 and the connecting rod 15, and at the same time, the adjusting ball 2 16 rotates between the connecting rod 15 and the support frame 21, thereby supporting the four corners of the push plate 12, and the anti-skid pad 17 moves with the push plate 12.
