[0024] The embodiment of the present application provides a TFT color screen liquid crystal display module waterproof device, which effectively solves the technical problem that this waterproof device and the above-mentioned waterproof device both need to be fixed with threaded connections. During the process of disassembling and assembling the waterproof device, if the thread is damaged, the waterproof shell cannot be used. At this time, the entire waterproof shell needs to be replaced, which wastes resources.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution in the embodiment of the present application effectively solves the technical problem that the waterproof device and the above-mentioned waterproof device both need to be fixed by threaded connection. During the process of disassembling and assembling the waterproof device, if the thread is damaged, the waterproof shell cannot be used. At this time, the entire waterproof shell needs to be replaced, which wastes resources. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a TFT color screen liquid crystal display module waterproof device, which comprises a waterproof front shell 1, a display module body 2 and a waterproof rear shell 3. The display module body 2 is placed on a side of the waterproof front shell 1 close to the waterproof rear shell 3, and the waterproof rear shell 3 is placed above the waterproof front shell 1 and the display module body 2. Four connecting mechanisms are arranged on the outside of the waterproof front shell 1.

[0028] Each connecting mechanism includes a mounting hole 4, a mounting tube 5, an internal thread 6, a slide groove 7, a clamping block 8, a through hole 9 and a limiting hole 10;

[0029] The mounting hole 4 is provided on the outside of the waterproof front shell 1, the mounting tube 5 is slidably connected to the inside of the mounting hole 4, the internal thread 6 is provided on the inner side of the mounting tube 5, the slide groove 7 is provided on the side of the waterproof front shell 1 close to the mounting hole 4, the clamping block 8 is slidably connected to the inside of the slide groove 7, the through hole 9 is provided in the inside of the slide groove 7, the through hole 9 is communicated with the slide groove 7, the limiting hole 10 is provided on the outside of the mounting tube 5, and the clamping block 8 is slidably connected to the inside of the through hole 9 and the limiting hole 10.

[0030] By setting the internal thread 6 to cooperate with the mounting hole 4, when the internal thread 6 is damaged, the block 8 is pulled to release the connection between the block 8 and the limiting hole 10. At this time, the mounting tube 5 can be taken out from the inside of the mounting hole 4 using a tool. When installing a new mounting tube 5, the mounting tube 5 is inserted into the inside of the mounting hole 4. At this time, the block 8 is pushed through the through hole 9 to insert into the limiting hole 10 to fix the mounting tube 5. At this time, the display module is placed on the waterproof front shell 1, and then the waterproof rear shell 3 is fitted with the waterproof front shell 1 to fix the display module. At this time, the waterproof front shell 1 and the waterproof rear shell 3 form a waterproof shell to protect the display module. At this time, the screw on the waterproof rear shell 3 is turned to connect with the internal thread 6 to fix the waterproof rear shell 3 with the waterproof front shell 1. When the thread is damaged, the thread can be replaced without replacing the protective device, saving resources.

[0031] A spring 11 is fixedly connected inside each slide slot 7;

[0032] The spring 11 is fixedly connected to a side of the clamping block 8 away from the through hole 9 , so as to provide support for the connection between the clamping block 8 and the limiting hole 10 .

[0033] A fixed shaft 12 is fixedly installed inside each slide groove 7;

[0034] The spring 11 is movably sleeved on the outside of the fixed shaft 12 to limit the moving path of the spring 11 .

[0035] Each block 8 has a movable hole 13 formed on its exterior;

[0036] The clamping block 8 is slidably connected to the outside of the fixed shaft 12 through the movable hole 13 to prevent the fixed shaft 12 from affecting the movement of the clamping block 8 .

[0037] A card slot 14 is provided on one side of the waterproof rear shell 3 close to each card block 8;

[0038] The clamping block 8 is clamped in the clamping slot 14 to limit the movement of the clamping block 8 .

[0039] A limiting block 15 is fixedly mounted on the outside of the mounting tube 5;

[0040] The limiting block 15 is slidably connected to the inside of the mounting hole 4 , and the limiting hole 10 is provided outside the limiting block 15 , so that the clamping block 8 is directly aligned with the limiting hole 10 .

[0041] By setting the spring 11 and cooperating with the card slot 14, when the block 8 and the limiting hole 10 are released, the block 8 compresses the spring 11 due to the movement of the block 8. When the block 8 is inserted into the limiting hole 10, the spring 11 returns to its original state. At this time, the waterproof rear shell 3 is fitted with the waterproof front shell 1. At this time, the block 8 enters the inside of the card slot 14. At this time, the block 8 cannot move. At this time, the screw is turned to connect the screw with the internal thread 6 to connect the waterproof front shell 1 with the waterproof rear shell 3. At this time, the display module body 2 is clamped and fixed by the waterproof front shell 1 and the waterproof rear shell 3. The spring 11 provides support for the block 8 and the connection between the block 8 and the card slot 14, so as to improve the stability of the connection between the mounting tube 5 and the mounting hole 4, and avoid the reduction of the threaded connection stability caused by the upward movement of the mounting tube 5 during use.

[0042] Working principle:

[0043] When the internal thread 6 is damaged, the clamping block 8 is pulled to release the connection between the clamping block 8 and the limiting hole 10. At this time, the clamping block 8 compresses the spring 11, and the installation tube 5 can be taken out from the inside of the installation hole 4 using a tool;

[0044] When installing a new installation tube 5, push the block 8 to make the block 8 away from the installation hole 4. At this time, the block 8 compresses the spring 11 and inserts the installation tube 5 into the inside of the installation hole 4. At this time, release the block 8. Under the action of the spring 11, the block 8 is inserted into the inside of the limiting hole 10 through the through hole 9 to fix the installation tube 5. At this time, the display module is placed on the waterproof front shell 1, and then the waterproof rear shell 3 is fitted with the waterproof front shell 1 to fix the display module. At this time, the waterproof front shell 1 and the waterproof rear shell 3 form a waterproof shell to protect the display module. At this time, the block 8 enters the inside of the card slot 14. At this time, the block 8 cannot move. At this time, turn the screw on the waterproof rear shell 3 to connect with the internal thread 6 to fix the waterproof rear shell 3 with the waterproof front shell 1. When the thread is damaged, the thread can be replaced without replacing the protective device, saving resources.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
