When the positioning rod is rotated, the positioning plate can apply force to the fixed frame and cause a slight deformation of the fixed frame. At this time, the connection between the sealing gasket and the connecting ring can be made tighter, and the waterproof film can greatly improve the waterproofness of the digital tube.

[0015] By adopting the above technical solution, the light-transmitting plate can be arranged to cooperate with the built-in diode for display operation, and the retaining ring can place the light-transmitting plate and make the light-transmitting plate flush with the fixed frame.

[0016] In a preferred embodiment: both ends of the light-transmitting plate are provided with mounting grooves, both end inner walls of the fixing frame are provided with fixing grooves, one end inner wall of the fixing groove is fixedly connected with a fixing spring, one end of the fixing spring is fixedly connected with a fixing block, and a sliding fit is formed between the fixing block and the inner wall of the mounting groove.

[0017] By adopting the above technical solution, the fixing block can slide into the installation groove through the inner wall of the fixing groove under the elastic force of the fixing spring, thereby realizing the fixing of the light-transmitting plate.

[0018] In a preferred embodiment: a waterproof film is glued to the top of the light-transmitting plate, and the waterproof film is connected to the top of the fixing frame by gluing.

[0019] By adopting the above technical solution and setting the waterproof film, the gap between the fixed frame and the light-transmitting plate can be sealed, further improving the waterproof effect of the gap at the edge of the digital tube.

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] 1. This scheme inserts the connecting ring fixedly connected to the bottom plate into the connecting groove, so that the connecting ring and the sealing gasket are squeezed and sealed, which can waterproof the edge of the digital tube. Then, the positioning plate is tightly attached to the outer wall of the fixed frame, and the positioning rod is rotated to the positioning port and the positioning groove. The sliding of the limit block in the inner wall of the limit groove can avoid the gap between the positioning plate and the fixed frame. When the positioning rod is rotated, the positioning plate can apply force to the fixed frame and cause the fixed frame to deform slightly. At this time, the connection between the sealing gasket and the connecting ring can be made tighter, which can further enhance the waterproof effect of the edge of the digital tube.

[0022] 2. In this solution, the gap between the fixed frame and the light-transmitting plate can be sealed by a waterproof film, thereby further improving the waterproof effect of the gap at the edge of the digital tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] An edge waterproof LED digital tube, such as Figure 1-4 As shown, the digital tube body includes a bottom plate 1 and a fixed frame 2. A connecting groove 3 is provided at the bottom of the fixed frame 2. A connecting ring 4 is fixedly connected to the top of the bottom plate 1. A sliding fit is formed between the inner wall of the connecting groove 3 and the connecting ring 4. A plurality of evenly distributed and movable positioning plates 5 are provided on the outside of both ends of the fixed frame 2. A plurality of evenly distributed positioning openings 6 are provided at one end of the positioning plate 5. Positioning grooves 7 corresponding to the positioning openings 6 are provided on the outer walls of both ends of the fixed frame 2. The inner wall of the positioning groove 7 is connected to the inner wall of the positioning opening 6 by a same positioning rod 8 through a thread.

[0031] In one of the specific embodiments, both ends of the base plate 1 are provided with limiting grooves 9 corresponding to the positioning plate 5, and the inner wall of the limiting groove 9 is slidably connected to the limiting block 10. The limiting block 10 can slide in the inner wall of the limiting groove 9, so that the positioning plate 5 can fit the outer wall of the fixed frame 2, and a gap between the positioning plate 5 and the fixed frame 2 can be avoided, so as to improve the waterproofness of the digital tube.

[0032] It should be noted that the inner wall cross-section of the limit groove 9 is in a T-shaped structure, and the inner wall cross-section of the limit block 10 is in a T-shaped structure. The inner wall cross-section of the limit groove 9 with a T-shaped structure can limit the limit block 10 by the inner wall of the limit groove 9, thereby avoiding separation between the two.

[0033] like Figure 3 As shown, a sealing gasket 11 is fixedly connected to the inner wall of the connecting groove 3. The sealing gasket 11 is made of rubber. The cross-section of the sealing gasket 11 is a U-shaped structure. A cavity 12 is opened in the sealing gasket 11. The cavity 12 can increase the deformation ability of the sealing gasket 11, thereby reducing the gap between the sealing gasket 11 and the connecting ring 4, and also facilitates the insertion of the connecting ring 4 into the connecting groove 3, which can further improve the waterproofness of the digital tube.

[0034] In one specific embodiment, Figure 4 As shown, a retaining ring 13 is fixedly connected to the top of the inner wall of the fixed frame 2, and a light-transmitting plate 14 is placed on the top of the retaining ring 13. The light-transmitting plate 14 can cooperate with the built-in diode for display operation. The retaining ring 13 can place the light-transmitting plate 14 and make it flush with the fixed frame 2.

[0035] On the basis of the above embodiment, mounting grooves 15 are provided at both ends of the light-transmitting plate 14, and fixing grooves 16 are provided on the inner walls at both ends of the fixing frame 2. A fixing spring 17 is fixedly connected to the inner wall of one end of the fixing groove 16, and a fixing block 18 is fixedly connected to one end of the fixing spring 17. A sliding fit is formed between the fixing block 18 and the inner wall of the mounting groove 15. The fixing block 18 can slide into the mounting groove 15 through the inner wall of the fixing groove 16 under the elastic force of the fixing spring 17, so that the light-transmitting plate 14 can be fixed.

[0036] It is worth mentioning that a waterproof film 19 is glued to the top of the light-transmitting plate 14, and the waterproof film 19 is glued to the top of the fixed frame 2. The waterproof film 19 can seal the gap between the fixed frame 2 and the light-transmitting plate 14, thereby further improving the waterproof effect of the edge gap of the digital tube.

[0037] The working process and beneficial effects of the utility model are as follows: when assembling the digital tube, first insert the connecting ring 4 fixedly connected to the bottom plate 1 into the connecting groove 3, and the connecting ring 4 can be squeezed and sealed with the sealing gasket 11 to achieve a preliminary waterproof effect, and then make the positioning plate 5 close to the outer wall of the fixed frame 2, rotate the positioning rod 8 to the positioning port 6 and the positioning groove 7, and the limit block 10 slides on the inner wall of the limit groove 9, so as to avoid the gap between the positioning plate 5 and the fixed frame 2, thereby improving the waterproof effect of the digital tube, and when the positioning rod 8 rotates, the positioning plate 5 can apply force to the fixed frame 2 and cause the fixed frame 2 to deform slightly, at this time, the connection between the sealing gasket 11 and the connecting ring 4 can be made tighter, and the waterproof effect of the digital tube can be greatly improved in combination with the waterproof membrane 19.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
