[0023] Please see Figures 1-5 This utility model provides the following technical solution: a backplate for a liquid crystal display screen that is easy to assemble and disassemble, comprising a backplate body 1, rectangular blocks 2 connected to the front two sides of the backplate body 1, the front ends of the rectangular blocks 2 being fitted into the inner wall of the opening end of the liquid crystal display screen body 3, adjustment grooves 4 being opened on both sides of the back opening end of the liquid crystal display screen body 3, insert rods 5 being movably connected to the surface of the adjustment grooves 4, rubber sleeves 6 being fitted onto the longitudinal end surface of the insert rods 5, pull rings 7 being connected to the bottom surface of the longitudinal end of the insert rods 5, and the lateral end of the insert rods 5 being inserted into the surface of a slot 8 on the side away from the liquid crystal display screen body 3, the slot 8 being opened in the backplate body. On the longitudinal end surfaces of both sides, ventilation slots 9 are longitudinally opened on the rectangular cavity surface of the back plate body 1. A sliding rod 10 is connected to the surface where the bottom of the ventilation slot 9 intersects with the back plate body 1. A slider 11 is slidably connected to the surface of the sliding rod 10. One side surface of the slider 11 is connected to the longitudinal end surface of the ventilation mesh frame 12. A limiting block 13 is provided at the intersection of the transverse end and the longitudinal end of the top of the ventilation mesh frame 12. In this design, a large number of related components are set in the main body 3 of the liquid crystal display screen. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0024] Preferably, the insertion rod 5 is a "T" shaped integrated structure.

[0025] In practical use, the horizontal end of the plug 5 is used to insert it into the slot 8, thereby fixing the connection between the back panel body 1 and the LCD screen body 3.

[0026] Preferably, the adjusting groove 4 has an inverted "L" shape, and the longitudinal end of the adjusting groove 4 is provided with an annular groove, and the shape and size of the annular groove are adapted to the rubber sleeve 6.

[0027] In practical use, the groove opened at the longitudinal end of the adjustment groove 4 is used to easily engage and fix the position of the rubber sleeve 6, thereby fixing the position of the rubber sleeve 6 fitted in the adjustment groove 4.

[0028] Preferably, the adjustment groove 4 and the slot 8 intersect to form a "T" shaped structure.

[0029] In practical use, the "T"-shaped structure formed by the intersection of the adjustment groove 4 and the slot 8 facilitates the movement of the insertion rod 5 within it and allows for the connection between the back plate body 1 and the LCD display body 3.

[0030] Preferably, the inner wall of the limiting block 13 is connected to the T-shaped block 14, and the intersection of the limiting block 13 and the T-shaped block 14 is engaged with the limiting groove 15, which is located at the top of the slide rod 10.

[0031] In practical use, the two sets of T-shaped blocks 14 provided on the inner wall of the limiting block 13 can be engaged and fixed in the limiting groove 15 opened at the top of the slide rod 10, thereby fixing the connection between the limiting block 13 and the slide rod 10.

[0032] Preferably, the sliding rod 10, the ventilation mesh frame 12, the limiting block 13, the T-shaped block 14 and the limiting groove 15 form a snap-fit ​​connection structure.

[0033] In practical use, the sliders 11 connected to the longitudinal ends of the ventilation mesh frame 12 slide on the slide rod 10 to limit its range of movement. When the ventilation mesh frame 12 slides to the bottom of the ventilation slot 9, the limiting block 13 at the bottom of the transverse end of the ventilation mesh frame 12 and the T-shaped block 14 provided therein engage and fix it on the limiting groove 15 opened at the top of the slide rod 10, thereby fixing the position of the ventilation mesh frame 12 in the ventilation slot 9.

[0034] Preferably, a circular through groove is formed longitudinally on the surface of the slider 11, and the shape and size of the through groove are adapted to the slider 10.

[0035] In practical use, the through groove on the surface of the slider 11 facilitates sliding connection to the surface of the slide rod 10, thereby restricting the movement of the ventilation mesh frame 12.

[0036] Working principle: During the assembly of the LCD screen body 3, the rectangular protrusions on both sides of the opening end of the LCD screen body 3 are used to fit and fix the rectangular blocks 2 on both sides of the back plate body 1, so that the back plate body 1 can fit and abut against the opening end on the back side of the LCD screen body 3. Then, the insert rods 5, which are movably connected in the adjustment grooves 4 on both sides of the LCD screen body 3, move from the opening end of the adjustment grooves 4 on both sides of the LCD screen body 3 towards the back plate body 1, so that the horizontal end of the insert rod 5 is inserted into the slots 8 on both sides of the back plate body 1, thereby... The backplate body 1 is fixed on the back side of the LCD screen body 3. At this time, the insertion rod 5 is rotated downward so that the rubber sleeve 6 sleeved at its longitudinal end is locked in the adjustment groove 4 opened on both sides of the LCD screen body 3, thereby fixing the position of the insertion rod 5. After the backplate body 1 is installed, when the electronic components in the LCD screen body 3 generate heat, ventilation and heat dissipation are carried out through the ventilation groove 9 and ventilation mesh frame 12 on the back side of the backplate body 1. However, the surface of the ventilation mesh frame 12, which is exposed to the environment for a long time, is prone to dust and other impurities adhering to it, which will block the ventilation holes on the ventilation mesh frame 12.

[0037] At this time, the ventilation mesh frame 12 fixed on the back plate body 1 needs to be disassembled and replaced periodically. Hold the horizontal end of the top of the ventilation mesh frame 12 and pull out the limiting block 13 and T-shaped block 14 that are engaged and fixed in the limiting groove 15 at the top of the slide rod 10. This allows the slider 11 that is slidably connected to the slide rod 10 to slide upward. Then, the ventilation mesh frame 12 that is engaged in the ventilation groove 9 can be taken out and replaced. When installing a new or cleaned ventilation mesh frame 12, repeat the above operation. Use the slider 11 connected to the longitudinal ends on both sides of the ventilation mesh frame 12 to slide on the slide rod 10, thereby limiting its range of movement. When the ventilation mesh frame 12 slides to the bottom of the ventilation groove 9, the limiting block 13 at the bottom of the horizontal end of the ventilation mesh frame 12 and the T-shaped block 14 provided therein engage and fix on the limiting groove 15 opened at the top of the slide rod 10, thereby fixing the position of the ventilation mesh frame 12 in the ventilation groove 9.

[0038] When it is necessary to disassemble the backplate body 1 to facilitate the maintenance and repair of the components inside the LCD screen body 3, pull the pull rings 7 at the bottom of the two side plug rods 5 in sequence and pull them outward, so that the rubber sleeve 6 engaged in the adjustment groove 4 is disengaged from the engagement groove. Then, hold the longitudinal end of the plug rod 5 and rotate it upward so that it is at a 90-degree angle to the original engagement position. Then move it to the side of the LCD screen body 3 away from the backplate body 1, so that the position of the plug rod 5 inserted in the slot 8 is disengaged from the slot 8, thereby making it easy to remove the backplate body 1 that is inserted and fixed at the opening end of the LCD screen body 3.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
