Description

Technical Field

[0001] The utility model belongs to the technical field related to displays, and particularly relates to a sealing and waterproof structure of a display screen. Background Art

[0002] The sealing structure of a display refers to a series of designs and materials used to protect the internal components of the display from external environmental factors (such as dust, moisture, temperature changes, etc.). This structure is crucial to ensure the normal operation and long service life of the display, especially in harsh environments or outdoor applications. It can well ensure the stability of the display, but it still has the following disadvantages in actual use:

[0003] During the installation of the display waterproof structure, only the display surface of the display is sealed and waterproofed, and the display circuit and circuit connection positions are directly dustproof and waterproofed through the interface and circuit connection. When the interface and circuit become loose, or when they need to be transported, the interface and other positions are exposed, and the protection of the display is not comprehensive enough;

[0004] After the display waterproof structure is installed, the edges of the display and other locations are directly sealed for waterproof protection. However, during the protection process, long-term outdoor work and shaking during transportation will cause the tightness of the gaps to change, reducing the sealing effect. Dust, moisture, etc. will enter the waterproof structure and then enter the gaps in the display body, causing damage to the display. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0027] See also Figure 1-7The utility model is a sealing and waterproof structure of a display screen, comprising a through shell 1, a movable plate 2, a threaded rod 3 and a sealing pressing plate 4. Both sides of the through shell 1 are through-set, and the through shell 1 fixes a fixed frame 101, a sealing strip 102, a flexible strip 103 and a sealing plate 104 therein. A fixed frame 101 is fixed on the front side of the through shell 1, and the flexible strip 103 is fixed therein through the fixed frame 101, and a display body 5 is movably connected through the flexible strip 103. A flexible strip 103 is fixed on the inner wall of the fixed frame 101. The interior of the fixed frame 101 is hollow, and one side of the fixed frame 101 close to the center of the through shell 1 is open. A sealing strip 102 is fixed on the edge of the fixed frame 101 close to the side of the through shell 1, and the sealing strip 102 is fixed on the inner wall of the through shell 1. After the sealing strip 102 is abutted by the sealing pressing plate 4, the display body 5 is limited to be sealed between the sealing plate 104 and the sealing strip. Between the sealing plates 4, a socket 105 is provided in the middle of the rear part of both ends of the through-shell 1. The through-shell 1 is movably connected to the movable plate 2 through the socket 105. The two sockets 105 are commonly movably connected with the movable plate 2. The movable plate 2 is threadedly connected with a threaded rod 3. After the movable plate 2 is inserted into the two movable openings on the through-shell 1, the threaded rod 3 can be screwed into the movable plate 2 to push the rubber pressure block 301 to abut against the sealing pressure plate 4. The front end of the threaded rod 3 is rotatably connected with the rubber pressure block 301. The front end of the rubber pressure block 301 is provided with a sealing pressure plate 4. A flexible pressure block 405 is fixed at the front center of the sealing pressure plate 4. The rubber pressure block 301 and the sealing pressure plate 4 abut against each other. The threaded rod 3 is rotated to make the rubber pressure block 301 abut against the sealing plate 104 until the flexible pressure block 405 on the sealing pressure plate 4 abuts against the display body 5, so that the position of the display body 5 on the flexible strip 103 is well restricted.

[0028] Specifically, a flexible strip 103 is fixed on the inner wall of the fixed frame 101, and a sealing plate 104 is fixed inside the flexible strip 103. The front sides of the fixed frame 101, the flexible strip 103 and the sealing plate 104 are all flush with the front side of the through-shell 1. The fixed frame 101 fixes the sealing plate 104 thereon through the flexible strip 103. The sealing plate 104 cooperates with the flexible strip 103, so that when water is poured or splashed onto the front side of the through-shell 1, the front side of the display body 5 is waterproof.

[0029] Furthermore, a rotating frame 302 is fixed to the rear end of the threaded rod 3 , and the diameter of the threaded rod 3 is equal to the diameter of the rubber pressing block 301 . By rotating the rotating frame 302 , the threaded rod 3 is driven to rotate in the movable plate 2 .

[0030] Furthermore, the display body 5 is movably connected in the flexible strip 103 behind the sealing plate 104, the rear side of the display body 5 abuts against the flexible pressure block 405, and the sealing pressure plate 4 abuts against the sealing strip 102. After the sealing pressure plate 4 abuts against the sealing strip 102, the space in the through-shell 1 between the sealing pressure plate 4 and the sealing plate 104 is sealed.

[0031] The operation process of this embodiment is as follows: when working, first place the sealing plate 104 in the through shell 1 downward and the rear part upward on the operating table, then place the display body 5 in the flexible strip 103, and then place the sealing pressure plate 4 in the through shell 1, and then pass the movable plate 2 through the two sockets 105 on the through shell 1, and then pass the rubber pressure block 301 on the threaded rod 3 through the movable plate 2, and then rotate the rotating frame 302 to make the threaded rod 3 rotate until the rubber pressure block 301 is pushed to abut against the sealing pressure plate 4, so that the flexible pressure block 405 on the sealing pressure plate 4 is pressed onto the display body 5, and the sealing pressure plate 4 and the sealing strip 102 are abutted against each other, so that the space between the sealing plate 104 and the sealing pressure plate 4 is sealed, and the position of the display body 5 in the flexible strip 103 is restricted. After completion, the through shell 1 is erected so that the display body 5 is installed in the through shell 1. Specific embodiment 2

[0033] Specifically, a connecting hole 404 is formed through the lower part of the sealing pressure plate 4, and a rubber sleeve 403 is fixed to the outer side of the connecting hole 404 on the rear side of the sealing pressure plate 4. The sealing pressure plate 4 is connected to the rubber sleeve 403 through the connecting hole 404. When the display body 5 is installed, the circuit of the display body 5 is passed through the connecting hole 404 and the rubber sleeve 403. After the installation is completed, tape is attached to the circuit and the rubber sleeve 403, and then glue is applied to the tape to seal it, so that the gap between the circuit and the rubber sleeve 403 is completely closed.

[0034] The operation process of this embodiment is as follows: when installing the display body 5, the circuit of the display body 5 is passed through the connecting hole 404 and the rubber sleeve 403. After the installation is completed, the tape is attached to the circuit and the rubber sleeve 403, and then glue is applied to the tape to seal it, so that the gap between the circuit and the rubber sleeve 403 is completely sealed. After the display body 5 is installed in the through-shell 1, the connector at the end of the exhaust pipe 401 is connected to the negative pressure device, and the negative pressure device is started. The negative pressure device generates a negative pressure between the sealing plate 104 and the sealing pressure plate 4, so that the sealing plate 104 and the sealing pressure plate 4 are sealed. Then the control valve 402 is closed again, so that the control valve 402 closes the exhaust pipe 401, and the connector of the exhaust pipe 401 and the negative pressure device are disconnected, and the space between the through-shell 1 between the sealing plate 104 and the sealing pressure plate 4 is evacuated, so that the space between the through-shell 1 between the sealing plate 104 and the sealing pressure plate 4 maintains a negative pressure, and the installation and tightening of the sealing structure are maintained.
