[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, the first embodiment of the present invention provides an explosion-proof liquid crystal splicing screen, including a mounting frame 1, a liquid crystal display screen 2 is provided on the front of the mounting frame 1, a clamping assembly 3 is provided in the inner cavity of the mounting frame 1, and a notch 4 is provided on the outside of the mounting frame 1;

[0022] The clamping assembly 3 includes a gear 301, the shaft end of which is arranged on the mounting frame 1. The outer surface of the gear 301 is meshedly connected with a movable plate 303. The outer side of the movable plate 303 extends to the outside of the mounting frame 1. A limit block 302 is arranged on the outer side of the movable plate 303. The inner side of the limit block 302 is connected to the inner wall of the mounting frame 1.

[0023] By pressing the movable plate 303 on one side, the movable plate 303 is driven to move on the limit block 302. Through the limitation of the limit block 302, the movable plate 303 has a good limiting effect when moving, so as to prevent it from position displacement. At the same time, through the engagement between the movable plate 303 and the gear 301, the gear 301 is driven to rotate around the shaft end, and then the gear 301 drives the other end of the movable plate 303 to move to the inner cavity of the mounting frame 1, so that it releases the clamping connection between the LCD screen 2 and other LCD screens 2, making it easy to disassemble the spliced ​​screen, which brings convenience to the operator.

[0024] Example 2

[0025] like Figure 3 and Figure 4 As shown, this embodiment includes the features of embodiment 1, and the distinguishing technical feature is that a connecting rod 304 is provided on the outer side of the limit block 302, and the outer side of the connecting rod 304 extends to the inside of the movable plate 303;

[0026] When the movable plate 303 is pressed, the rear end portion of the movable plate 303 moves on the outer surface of the limit block 302, and the front end portion of the movable plate 303 moves on the connecting rod 304, thereby preventing position displacement through the limitation between the limit block 302, the connecting rod 304 and the movable plate 303, and preventing the movable plate 303 from being unable to reset after being pressed.

[0027] The movable plate 303 is provided with teeth on its inner side, and the outer surface of the teeth is meshed with the outer surface of the gear 301;

[0028] When the movable plate 303 moves inward, the teeth engage with the gear 301, driving all movable plates 303 to move to the inner cavity of the mounting frame 1, thereby releasing the clamping between the splicing screens, making it easier for the operator to disassemble the splicing screen, and bringing convenience to the operator.

[0029] There are four movable plates 303 , which are respectively arranged around the gear 301 and cross-distributed.

[0030] By providing four movable plates 303 , the four movable plates 303 can be used to be clamped between the splicing screens on all sides, so as to facilitate the clamping and fixing of the splicing screens and make them more firmly fixed.

[0031] Among them, a spring 305 is provided on the outside of the limit block 302, and the other end of the spring 305 is connected to the inner wall of the movable plate 303;

[0032] At this time, since the spring 305 is in an extruded state, it will apply outward pressure to the movable plate 303 as a whole, making it easier to drive the movable plate 303 to snap into the slot 4 on the adjacent splicing screen. By snapping the ends of the four movable plates 303, the splicing screens are fixed to each other to form a whole, which is convenient for people to watch and use.

[0033] The ends of the four movable plates 303 are all set to arcs, and the arcs on the four movable plates 303 are all facing the back;

[0034] When installing the splicing screen, the splicing screen is pressed onto the frame, and the screen is built by snapping the ends of the movable plates 303. However, after the splicing screen is built, it is impossible to place the splicing screen any further. The outer arc of the movable plate 303 facilitates squeezing it onto the screen, thereby forming a complete screen. At the same time, when disassembling the screen, it is only necessary to press the movable plate 303 on the splicing screen at the edge of the screen, and retract the four movable plates 303 into the inner cavity of the mounting frame 1 through the gear 301 to release the fixation, and remove the splicing screen as a whole from the screen, thereby improving the work efficiency of installation and disassembly.

[0035] A protective cover is provided on the outside of the liquid crystal display screen 2, and an adhesive sponge is provided on the inside of the protective cover;

[0036] The LCD screen 2 is protected by a protective cover, and the combined LCD screen body is buffered and protected in multiple directions by an adhesive sponge, which effectively prevents the combined LCD screen body from being squeezed and damaged due to external collisions, thereby improving the safety and reliability of the LCD screen 2.

[0037] The working principle and use process of this utility model:

[0038] First, when the operator is installing the splicing screen, he or she installs the splicing screen on the frame and fixes it to the frame by interlocking the movable plates 303. Then, when the operator installs the splicing screen in the last row, he or she squeezes the entire splicing screen into the screen frame through the arc at the end of the movable plate 303 to complete the fixation.

[0039] However, when disassembling, by pressing the movable plate 303 on the splicing screen outside the screen, the movable plate 303 is driven to move on the outer surface of the limiting block 302 and the connecting rod 304, so that the movable plate 303 is limited to move, then the gear 301 is driven to rotate by the movable plate 303, and the other three movable plates 303 are driven to move to the inner cavity of the mounting frame 1 by the gear 301, so that the fixing between the adjacent splicing screens is released, thereby facilitating the disassembly of the splicing screen from the whole screen, and the subsequent splicing screen is disassembled, the disassembly efficiency is improved, and the use of the operator is facilitated.

[0040] It should be noted that in this paper, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
