Description

Technical Field

[0001] This utility model relates to the field of LED screen technology, specifically to an LED screen with a fixed locking structure. Background Technology

[0002] LED backlights are mainly composed of components such as light source, light guide plate, optical film, and plastic frame. Backlights themselves have the characteristics of high brightness, long life and uniform light emission, which makes backlight technology more and more mature. Nowadays, backlights can be used in various fields, including the interior of automobiles. However, the installation of in-vehicle screens in automobiles is very troublesome. It requires a series of tools to complete the installation, which affects the overall work efficiency. Moreover, the subsequent positioning and limiting effect is not particularly perfect.

[0003] In response, Chinese utility model patent CN218159492U discloses a vehicle-mounted LED backlight with a fixed mounting structure, comprising: a base, reinforcing blocks, a base plate, and a main unit. Reinforcing blocks are symmetrically fixedly installed at both ends of the base. The base plate is slidably installed inside the base, and the main unit is slidably installed inside the base plate. A positioning device is fixedly installed inside the base plate, and a limiting device is fixedly installed inside the base. Compared to traditional LED backlights, this device allows for precise and stable positioning and installation of the main unit, accelerating overall installation efficiency. It eliminates the need for various auxiliary tools, significantly improving the device's efficiency and ensuring its working quality. It also facilitates quick and stable replacement and adjustment of the main unit, greatly reducing the difficulty of maintenance and replacement, thus making subsequent use and maintenance of the device more convenient.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-7 This is the first embodiment of the present utility model. The present utility model provides a technical solution: an LED screen with a fixed carding structure, including a base 1, a base plate 2 slidably connected inside the base 1, a main body 5 slidably connected inside the base plate 2, openings 24 on both sides of the base plate 2, and card slots 25 on both sides of the main body 5.

[0031] The base 1 has slots 23 at both ends of its top surface. A sliding groove 8 is formed on the bottom surface of each slot 23. One end of a spring 9 is fixedly connected to one side of the sliding groove 8, and the other end of the spring 9 is fixedly connected to one side of a slider 10. A limiting rod 11 is fixedly connected to the other side of the slider 10. The slider 10 is slidably connected to the sliding groove 8, and the limiting rod 11 is slidably connected to the through-hole 24 and the slot 25. A connecting block 12 is fixedly connected to the top surface of the slider 10. A fixing rod 13 is fixedly connected to one side of the connecting block 12. A limiting round block 14 and a connecting round block 15 are rotatably connected inside the fixing rod 13. A connecting rod 15 is fixedly connected to one side of the limiting round block 14. One end of the round block 15 is connected to the other end of the round block 15 and fixed to the actuating plate 16. A limiting hole groove 161 is opened on one side of the actuating plate 16 and a limiting hole groove 162 is opened on the other side of the actuating plate 16. A sliding groove 17 is opened on one side of the groove 23. One end of the second spring 18 is fixed to one side of the sliding groove 17. The other end of the second spring 18 is fixed to the moving plate 19. A limiting rod 20 is fixed to one side of the moving plate 19. The limiting rod 20 is engaged with the limiting hole groove 161. A fixing plate 21 is fixed to one side of the groove 23. A limiting rod 22 is fixed to one side of the fixing plate 21. When it is necessary to remove the main body 5 and the base plate 2, the movable plate 19 can be moved to compress the spring 18, causing the limiting rod 20 on one side of the movable plate 19 to disengage from the limiting hole slot 161 on one side of the movable plate 16, thus releasing the limitation on the movable plate 16. The movable plate 16 can then be rotated and moved, causing the slider 10 to move accordingly and compress the spring 9, moving the slider 10 to a suitable position. The limiting lever 11 can then move and disengage from the slot 25 and the through 24, and the movable plate 16 can move to a suitable position. Rotating the movable plate 16 to a horizontal position allows the limiting hole slot 162 on one side of the movable plate 16 to engage with the limiting rod 22 on one side of the fixed plate 21, thus limiting the movable plate 16 and the position of the limiting lever 11 after movement, facilitating the removal of the main body 5 and the base plate 2.

[0032] Example 2:

[0033] Please see Figure 1-7 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The two ends of the top surface of the main body 5 are respectively fixed to the toggle frame 6 to facilitate the picking and placing of the main body 5. The two ends of the top surface of the bottom plate 2 are respectively fixed to the handle 4 to facilitate the picking and placing of the bottom plate 2.

[0034] Multiple positioning holes 51 are opened on the top surface of the main body 5, and multiple positioning rods 3 are fixedly installed in the base plate 2. The positioning holes 51 are slidably connected to the positioning rods 3, which can be further limited and positioned during the installation of the main body 5.

[0035] A groove 131 is formed on one side of the fixing rod 13, and a groove 132 is formed on one side inside the groove 131.

[0036] The connecting block 15 is rotatably connected within the first groove 131, and the limiting block 14 is rotatably connected to the second groove 132. The vertical cross-sectional size of the connecting block 15 is smaller than that of the limiting block 14.

[0037] The outer surface of the limiting circular block 14 is fixedly connected to the limiting rotating block 141. The inner wall of the groove 132 is provided with a limiting rotating groove 1321. The limiting rotating block 141 is slidably connected to the limiting rotating groove 1321, which can limit the rotation range of the actuating plate 16. The rotation range is from zero to ninety degrees, so that the actuating plate 16 can be rotated to a horizontal state and a vertical state, which facilitates the limiting rod 20 or the limiting rod 22 to limit the limiting hole groove 161 or the limiting hole groove 2162 on one side of the actuating plate 16.

[0038] One side of the actuating plate 16 contacts one side of the fixed rod 13, and one side of the moving plate 19 contacts the actuating plate 16.

[0039] The through-hole 24 and the slot 25 are internally connected. Limiting blocks 101 are fixedly connected to both sides of the slider 10. Limiting slots 81 are opened on both sides of the slide groove 8. The limiting blocks 101 are slidably connected to the limiting slots 81, which can limit the range of movement of the slider 10 and improve the stability of the slider 10.

[0040] Limiting blocks 191 are fixedly connected to the top and bottom surfaces of the movable plate 19, and limiting grooves 171 are opened on the top and bottom surfaces of the sliding groove 17. The limiting blocks 191 are slidably connected to the limiting grooves 171, which improves the stability of the movement of the movable plate 19 and can effectively limit the range of movement of the movable plate 19.

[0041] The base 1 is fixed to two sides with reinforcing plates 7 respectively. The reinforcing plates 7 have reinforcing holes and slots 71 to facilitate the reinforcement and positioning of the reinforcing plates 7, making the base 1 more stable during use.

[0042] Please see Figure 1-7In actual use, the base plate 2 is placed inside the base 1, and the main body 5 is placed inside the base plate 2. By pulling the actuating plate 16, the limiting slot 162 is disengaged from the limiting rod 22 on one side of the fixing plate 21, thus releasing the limitation on the actuating plate 16. Then, rotating the actuating plate 16 causes the actuating plate 16, the fixing rod 13, the connecting block 12, and the slider 10 to pop out and move under the action of the spring 9. The limiting rod 11 moves accordingly and engages in the through-hole 24 of the base plate 2 and the slot 25 of the main body 5, thus limiting and fixing the base plate 2 and the main body 5. Then, the moving plate 19 can be manually moved to compress the spring 18, leaving space for the actuating plate 16 to rotate, so that the actuating plate 16 rotates to a horizontal position. When the movable plate 19 is released, it moves under the action of the second spring 18, causing the limiting hole groove 161 on one side of the actuating plate 16 to engage with the limiting rod 20 on one side of the movable plate 19. This further limits the actuating plate 16 and improves the stability of the limiting rod 11 engaging the through port 24 and slot 25. The movable plate 19, limiting rod 20, fixing plate 21, and limiting rod 22 can further limit and fix the actuating plate 16 after it is actuated. Thus, the limiting rod 11 can limit or disengage the through port 24 and slot 25, allowing the base plate 2 and the main body 5 to be disassembled and installed simultaneously. This facilitates the disassembly and assembly of the base plate 2 and the main body 5.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
