Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to an embedded installation structure for waterproof and dustproof sealing strips for displays. Background Technology

[0002] In the modern electronic device usage environment, displays face a variety of potential threats. In outdoor environments, displays may be corroded by rain and dust. Traffic sign displays and outdoor advertising display equipment are exposed to the natural environment for a long time. Without good waterproof and dustproof measures, moisture entering the display can cause short circuits, and dust accumulation can affect the heat dissipation and optical performance of the display, thereby shortening the lifespan of the display.

[0003] The development of sealing materials has provided protection for the application of sealing strips. Early sealing materials had limited performance. With the advancement of materials science, various high-performance rubber and silicone materials have emerged. These materials have good elasticity, aging resistance, and chemical corrosion resistance, making them very suitable for making sealing strips. Compared with other sealing methods, embedded installation structures have better stability and reliability. When the sealing strip is embedded in the mounting groove of the display screen, it can be constrained in multiple directions and is not easy to shift. Traditional strip installation steps are cumbersome, requiring tweezers to align the gaps for installation, which is time-consuming, labor-intensive, and requires a lot of manual intervention, and is easy to injure the workers' hands.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of an embedded installation structure for a waterproof and dustproof sealing strip for a display screen, comprising a housing 1, a rotating shaft 3 rotatably connected to the bottom left side of the housing 1, a rolling disk 4 rotatably connected to the outer wall of the middle part of the rotating shaft 3, a rotating column 10 rotatably connected to the left side of the middle part of the housing 1, a gear 9 fixedly connected to the outer wall of the middle part of the rotating column 10, making the structure more complete, a gear 6 meshingly connected to the right side of the gear 6, a rotating shaft 7 fixedly connected to the top rear side of the gear 6, a rotating shaft 5 rotatably connected to the middle part of the gear 6, a transmission column 8 rotatably connected to the right side of the rotating shaft 7, so that when one side rotates, the other side can rotate accordingly, a rotating column 11 fixedly connected to the middle part of the right gear 9, a limiting disk 12 fixedly connected to the front side of the rotating column 10, a limiting disk 13 slidably connected to the front side of the rotating column 10 near the edge, and an expansion mechanism 2 provided on the left side of the housing 1, the expansion mechanism 2 being used to widen the distance between the display screen and the frame for better sealing of the sealing strip;

[0032] Specifically, the bottom left side of the outer casing 1 is rotated via a pivot 3. The outer wall of the pivot 3 is cleverly connected to the rolling disk 4, allowing users to easily perform rolling operations. A pivot 10 is also located on the left side of the middle of the outer casing 1, which is not only sturdy but also practical. A gear 9 is fixedly connected to the outer wall of the pivot 10, making the entire structure more complete and compact. The right side of gear 9 meshes with gear 6. A pivot 7 is fixedly connected to the top rear side of gear 6, while a pivot 5 is rotatably connected to its middle section, ensuring smooth and precise rotation. A transmission column 8 is rotatably connected to the right side of pivot 7, ensuring smooth rotation even when one side is rotating. On the other side, it can rotate in a timely and accurate manner, thus achieving efficient power transmission. On the right side, a rotating column 11 is fixedly connected to the middle of gear 2 9, which further enhances the stability and reliability of the structure. A limiting disc 12 is fixedly connected to the front side of rotating column 2 10, and a limiting disc 2 13 is slidably connected near the edge on the front side. This can effectively limit the rotation range and prevent damage caused by excessive rotation. In addition, an expansion mechanism 2 is specially provided on the left side of the outer casing 1. This mechanism is used to provide sufficient distance between the display screen and the frame to ensure a better sealing effect, prevent the intrusion of dust and moisture, and thus extend the service life of the equipment.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The expansion mechanism 2 includes a rotating column 201, the middle of which is rotatably connected to the middle left side of the outer shell 1. A swing column 202 is provided at the top of the rotating column 201. A telescopic column 203 is fixedly connected to the bottom right side of the swing column 202, forming a single unit for better adjustment. A limit block 204 is fixedly connected to the middle front side of the outer shell 1. A T-shaped column 205 is fixedly connected to the left side of the swing column 202. An expansion cutter head 206 is fixedly connected to the bottom of the T-shaped column 205. A small circular hole 208 is provided near the edge of the lower left side of the outer shell 1. A knob 207 is slidably connected to the inner wall of the small circular hole 208. The knob 207 fixes the swing column 202 so that it no longer moves up and down.

[0034] Specifically, the expansion mechanism 2 includes a rotating column 201, which is rotatably connected to the middle left side of the outer casing 1. To achieve better adjustment, a swing column 202 is provided at the top of the rotating column 201, and a telescopic column 203 is fixedly connected to the bottom right side of the swing column 202. These three are connected together to provide more flexible and precise adjustment capabilities. In addition, a limit block 204 is fixedly connected to the middle front side of the outer casing 1 to ensure the stability and safety of the mechanism in a specific position. A T-shaped column 205 is also fixedly connected to the left side of the swing column 202, and an expansion cutter head 206 is fixedly connected to the bottom of the T-shaped column 205 for performing specific expansion operations. To further enhance the convenience of operation, a small circular hole 208 is provided near the edge of the lower left side of the outer casing 1. A knob 207 is slidably connected to the inner wall of the hole. The function of the knob 207 is to fix the swing column 202 and prevent it from moving up and down unnecessarily during use, thereby ensuring the accuracy and stability of operation.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 A dustproof box 14 is fixedly connected to the middle of the rear side of the inner wall of the outer shell 1. A sleeve 15 is fixedly connected to the front side of the limiting disc 13. A cover plate 16 is fixedly connected to the outer wall of the sleeve 15, so that the cover plate 16 can be removed and replaced with a new rubber strip. Screws 17 are threadedly connected to both the left and right sides of the cover plate 16. Limiting posts 18 are fixedly connected to the front and rear sides of the rotating column 11 near the edge. Multiple fixing blocks 20 are fixedly connected to the bottom of the outer shell 1, so that the bottom structure is complete.

[0036] Specifically, a dustproof box 14 is fixedly connected to the middle of the rear side of the inner wall of the outer casing 1. This effectively prevents dust and other impurities from entering the interior of the outer casing 1, thus protecting the internal precision components. Simultaneously, a sleeve 15 is fixedly connected to the front side of the limiting disc 13, and a cover plate 16 is fixedly connected to the outer wall of the sleeve 15. This structure allows the cover plate 16 to be easily removed for users to replace the rubber strip, thereby extending the service life of the equipment. Furthermore, both sides of the cover plate 16 have threaded connections, ensuring its firmness and preventing loosening during use. To further improve the stability and durability of the equipment, limiting posts 18 are fixedly connected to the front and rear sides of the rotating column 11 near the edges. This effectively limits the movement range of the rotating column 11, preventing excessive rotation and damage. Finally, the bottom of the outer casing 1 is designed with multiple fixing blocks 20 fixedly connected. These fixing blocks 20 make the bottom structure of the outer casing 1 more complete, improving the overall stability of the equipment and ensuring stable operation in various environments.

[0037] Please see the appendix Figure 3 - Appendix Figure 5 The bottom of the fixing block 20 is fixedly connected to the bottom edge 19, and the bottom of the bottom edge 19 is fixedly connected to the rough edge 21. The bottom right side of the outer shell 1 is fixedly connected to the reflective sticker 22. The outer wall of the rolling disk 4 is fixedly connected to the locking strip 23, so that the adhesive strip is locked and stable in the middle of the locking strip 23. The front side of the rotating column 1 201 is fixedly connected to the limiting block 24. The top left side of the outer shell 1 is fixedly connected to the lighting lamp 25 to provide necessary light and facilitate installation.

[0038] Specifically, the bottom of the fixing block 20 is fixedly connected to the bottom edge 19 through a structural connection method, and the bottom of the bottom edge 19 is also fixedly connected to the rough edge 21 through a structural connection method. This can enhance the stability and durability of the device. The bottom right side of the outer shell 1 is fixedly connected to the reflective sticker 22 through a structural connection method. The function of the reflective sticker 22 is to reflect light in the case of insufficient light, improve the visibility of the device, and ensure safe use. The outer wall of the rolling disk 4 is fixedly connected to the locking strip 23 through a structural connection method. The function of the locking strip 23 is to allow the rubber strip to be locked in the middle of the locking strip 23 and remain stable, thereby ensuring the normal operation of the device. The front side of the rotating column 1 201 is fixedly connected to the limiting block 24 through a structural connection method. The function of the limiting block 24 is to limit the rotation of the rotating column 1 201 when it rotates to a certain position, prevent the rotating column 1 201 from rotating excessively, and thus protect the device. The top left side of the outer shell 1 is fixedly connected to the lighting lamp 25 through a structural connection method. The function of the lighting lamp 25 is to provide necessary light in the case of insufficient light, facilitate installation and use, and improve the ease of use.

[0039] Working principle: When the adhesive strip needs to be installed, hold the right side of the outer casing 1 and align the left scrolling disk 4 with the middle of the screen edge and frame. Scrolling causes the adhesive strip to be installed along the locking strip 23 between the display screen and the frame. The adhesive strip ring is placed between the limiting disc 12 and the limiting disc 23. During installation, the scrolling disk 4 consumes the adhesive strip, causing the rotating column 20 to rotate, which drives the gear 29 to rotate, causing the meshing gear 16 to rotate as well. The transmission column 8 is fixed on the gear 16. The rotation of the transmission gear 16 causes the rotating column 31 on the right side to rotate in the same way. This allows the used adhesive strip to be tied to the limiting disc 12 on the right side, completing the installation process. The installation process is simple and the safety is greatly improved.

[0040] When installing the adhesive strip, if the distance between the display screen and the frame is too narrow to install directly, simply turn the knob 207 so that the right side of the swing column 202 rotates downward around the rotating column 201, and the expanding head 206 falls downward, widening the distance between the display screen and the frame in front of the rolling disk 4. The bottom of the telescopic column 203 is locked on the left side of the limiting block 204, and the expanding head 206 will not run to the right, making it easier to install the adhesive strip.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
