[0002] The display screen mainly consists of a display module and a control box. The control box is usually installed on the back of the display module and is electrically connected to the display module. Therefore, the waterproofness of the connection between the two is crucial. Once water enters, it can easily damage the equipment.

[0003] In the prior art, for example, Chinese utility model patent with patent number ZL202223421658.9 discloses an LED display profile cabinet with a waterproof structure, including a frame and a profile control box fixedly installed in the frame; the profile control box is provided with at least one receiving control card, and the front of the receiving control card is provided with a two-in-one connector for connecting and cooperating with the display module; the profile control box includes a box body and at least one front cover plate that cooperate with each other, a waterproof gasket is provided between the front cover plate and the box body, the front of the front cover plate is provided with a connector through hole, the two-in-one connector extends into the connector through hole, and a waterproof sealing ring for cooperating with the display module is fixed around the connector through hole on the front of the front cover plate.

[0004] As mentioned above, existing displays typically connect the control box and display module using bolts, and a waterproof sealing ring is installed on the connection surface to achieve waterproofing. Therefore, this type of waterproof structure requires the bolts to be tightened as much as possible to ensure a tight connection between the control box and the display module, thus guaranteeing the waterproof performance of the sealing ring. Consequently, disassembling the control box for maintenance is time-consuming and labor-intensive. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-3 As shown, this embodiment provides a waterproof structure for a display screen. The display screen mainly includes a display module 1 and a control box 2. This waterproof structure is disposed between the display module 1 and the control box 2. Specifically, the waterproof structure includes a first waterproof component 3 embedded in the back of the display module 1 and a second waterproof component 4 installed on the control box 2. The first waterproof component 1 has an insertion groove, and the second waterproof component 4 has two circumferential positioning grooves on its side. Waterproof rings 5 ​​are provided in the positioning grooves. The insertion groove and the second waterproof component 4 have a wedge-shaped structure that matches each other. That is, the insertion groove has a structure whose size gradually increases from the inside to the outside, while the insertion end of the second waterproof component 4 has a structure whose size gradually decreases towards the end. In this way, the second waterproof component 4 can be smoothly inserted into the insertion groove of the first waterproof component 3, and during the insertion process, the pressure and friction between the two will gradually increase, thereby ensuring the stability of the insertion. Furthermore, the second waterproof component 4 is provided with two waterproof rings 5. Under the pressure between the two waterproof components, the waterproof effect of the waterproof rings 5 ​​is guaranteed. At the same time, the squeezed waterproof rings 5 ​​also further increase the frictional resistance between the two waterproof components, thus further ensuring the stability of the insertion.

[0030] The display module includes structural components and display components. The display components mainly include LED lights, a PCB board, and a driver IC, which are not shown in the figure. The structural components are made of aluminum profiles and serve as the carrier for the display components. They are mainly composed of a front side plate 11, a rear side plate 12, upper and lower side plates, and reinforcing ribs. The rear side plate 12 has an insertion slot for inserting the first waterproof component 3. The first waterproof component 3 has multiple elastic elements 31 on its side. The elastic elements 31 adopt a simple spring sheet structure. During the process of inserting the first waterproof component 3 into the structural component, the spring sheet structure is compressed. After the first waterproof component is fully inserted into the structural component, the spring sheet structure unfolds, and its free end abuts against the rear side plate 12. Thus, the inserted end of the first waterproof component 3 abuts against the front side plate 11, while the elastic elements 31 abut against the rear side plate 12, so as to achieve stable assembly of the first waterproof component 3 and the display module 1.

[0031] The front panel 11 has an electrical port for the electrical connection structure of the display component to extend into the first waterproof component. Correspondingly, as shown in Figures 4 and 5, the embedded end of the first waterproof component 3 has an opening 32 adapted to the electrical port. To ensure the positional stability of the first waterproof component 3 within the display module 1, the embedded end of the first waterproof component 3 has a positioning strip 33 that mates with the inner edge of the electrical port. Thus, the position of the first waterproof component 3 at this end is fixed, while the position at the other end is limited and fixed by the insertion port on the rear panel 12. Of course, since the embedded end of the first waterproof component 3 has an opening 32, to prevent the second waterproof component 4 from being inserted into the opening 32, a limiting platform 34 that abuts against the second waterproof component 4 is provided at the edge of the opening 32.

[0032] like Figure 6-8As shown, the second waterproof component 4 sequentially includes a plug-in portion 41, a limiting portion 42, and a mounting portion 43. The plug-in portion 41 protrudes from the control box, and a waterproof ring 5 is disposed on the plug-in portion 41. The mounting portion 43 is connected to the control box 2. The limiting portion 42 abuts against the display module 1 and the control box 2 on both sides, respectively. That is, the second waterproof component 4 accurately controls the size of its mating parts with the first waterproof component 3 and the control box 2 by setting the limiting portion 42. Among them, the mounting portion 43 is provided with multiple elastic buckles 431 on its side. During the process of the mounting portion 43 being inserted into the control box 2, the elastic buckles 431 are squeezed. When the elastic buckles 431 are fully inserted into the control box, the elastic buckles 431 naturally reset and unfold, thereby abutting against the inner side of the control box. At this time, the limiting portion 42 abuts against the outer side of the control box 2. The elastic buckles 431 and the limiting portion 42 together achieve a stable connection between the second waterproof component 4 and the control box 2. To improve the tightness of the connection between the second waterproof component 4 and the control box 4, an elastic pad 6 is provided on the side of the limiting part 42 near the mounting part 43. The elasticity of the pad ensures that the limiting part 42 and the elastic buckle 431 maintain a tight contact with the inner and outer sides of the control box 2. To prevent the elastic pad 6 from falling off the second waterproof component 4 during transfer, a retaining ring 61 is provided on the elastic pad 6, covering the edge of the limiting part 42, thus ensuring a stable connection between the elastic pad 6 and the limiting part 42. Furthermore, to improve the waterproofness at the connection between the second waterproof component 4 and the control box 2, the elastic pad 6 is provided with two annular waterproof grooves 62.

[0033] This utility model also provides a display screen, including a display module 1 and a control box 2 disposed on the back of the display module 1, with a waterproof structure as described above provided between the display module 1 and the control box 2.

[0034] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
