[0002] In outdoor security monitoring equipment, measuring instruments, and other equipment that needs to operate in harsh environments, waterproof sealing of rotating components is a critical issue. These devices typically operate for extended periods in harsh conditions such as rain, floods, and snow, thus placing high demands on the waterproof performance of rotating connections. Traditional waterproof rotating structures usually employ simple sealing rings or sealants for waterproofing, but these methods have some limitations:

[0003] Insufficient sealing performance: Traditional sealing rings or sealants are prone to aging and deformation after prolonged use, resulting in decreased sealing performance and inability to effectively prevent moisture from entering the equipment.

[0004] Poor rotational flexibility: While some sealing structures achieve waterproofing, they can increase friction between rotating parts, leading to uneven rotation or even jamming, which can affect the normal operation of the equipment.

[0005] Poor adaptability: Traditional sealing structures can only adapt to specific rotating parts shapes and sizes. For the diverse needs of different equipment, redesign and customization are required, which increases costs and design difficulty. Utility Model Content

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] The annular soft silicone ring is pressed into contact with rotating component one and rotating component two to achieve a seal;

[0010] The annular soft silicone ring includes a fixed side and a rotating side;

[0011] The fixed side is used to tighten and fix it to either rotating component one or rotating component two;

[0014] Preferably, the rotating housing is further provided with a bearing.

[0015] Preferably, the rotating bracket includes an outer shell, an inner shell detachably connected to the outer shell, a cable, a soft silicone part one, and a soft silicone part two;

[0016] The cable consists of a multi-strand wire harness and a double layer of acetate cloth wrapped around the multi-strand wire harness;

[0017] The double-layer acetate cloth is coated with glue to fill the gaps in the fine pores of the double-layer acetate cloth, making the multi-strand wire bundle waterproof when wrapped around it.

[0018] The soft silicone component one and soft silicone component two are disposed at both ends of the cable. The center of each soft silicone component one and soft silicone component two is provided with a through hole for the cable to pass through. The cable passes through the through hole, and the soft silicone component one and soft silicone component two are sealed with the double-layer acetate cloth through an adhesive layer.

[0019] The outer shell and inner shell are provided with contour groove 1 and contour groove 2 that match the outer contours of soft silicone part 1 and soft silicone part 2; the soft silicone part 1 and soft silicone part 2 are pressed into the contour groove 1 and contour groove 2, so that the contact surfaces of the soft silicone part 1 and soft silicone part 2 are tightly fitted with the contact surfaces of the contour groove 1 and contour groove 2.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0044] Reference Figures 1 to 7 This utility model provides a waterproof rotating structure, including: a rotating component 100 and a rotating component 200 that are rotatably connected to each other, and an annular soft silicone ring 6 provided at the rotating connection part of the rotating component 100 and the rotating component 200.

[0045] The annular soft silicone ring 6 achieves a seal by pressing and contacting the rotating component 100 and the rotating component 200; it can form a reliable sealing barrier at the rotating connection part, effectively preventing external moisture, liquids, etc. from entering the equipment and improving the sealing performance.

[0046] The annular soft silicone ring 6 includes a fixed side 601 and a rotating side 602. When the fixed side 601 is located on the inner wall of the annular soft silicone ring 6, the corresponding rotating side 602 is located on the outer wall of the annular soft silicone ring 6. When the fixed side 601 is located on the outer wall of the annular soft silicone ring 6, the corresponding rotating side 602 is located on the inner wall of the annular soft silicone ring 6. The fixed side 601 is used to tighten and fix it to the rotating component 100 or the rotating component 200. The tightening and fixing method of the fixed side 601 increases the friction. This ensures that when the annular soft silicone ring rotates, it will not deform due to simultaneous compression from the inner and outer walls, and uneven compression will not lead to waterproofing failure.

[0047] The rotating side 602 is provided with multiple spaced annular ribs, which make line contact with the rotating surfaces of rotating component 100 or rotating component 200. This line contact significantly reduces friction during rotation compared to traditional surface contact sealing. When rotating component 100 and rotating component 200 rotate relative to each other, the line contact between the annular ribs and the rotating surfaces greatly reduces the contact area, thereby lowering frictional resistance, improving rotational flexibility and smoothness, and reducing problems such as poor rotation or component wear caused by excessive friction.

[0048] Furthermore, the first rotating component 100 is configured as a rotating bracket, and the second rotating component 200 is configured as a rotating housing; the rotating housing is rotatably connected to both ends of the rotating bracket 100, and the rotating bracket is configured as L-shaped, with the rotating housing of the external device rotatably connected to the vertical end and the horizontal end of the rotating bracket.

[0049] By rotatably connecting the vertical and horizontal ends of the rotating housing and the rotating bracket, the rotating component can rotate flexibly in two different directions. This multi-directional rotation capability allows the equipment to quickly adjust the angle and direction of monitoring or measurement according to actual needs, improving the equipment's flexibility and adaptability. For example, in outdoor security monitoring, the direction of the surveillance camera can be quickly adjusted to achieve all-around monitoring coverage. The rotating housing is also equipped with a bearing 7, which further improves the rotational accuracy of the rotating component.

[0050] Furthermore, the rotating bracket 100 includes: a housing 1, an inner housing 2 detachably connected to the housing 1, a cable 3, a soft silicone part 4, and a soft silicone part 5;

[0051] The cable 3 is composed of a multi-strand wire harness and a double layer of acetate cloth wrapped around the multi-strand wire harness;

[0052] The double-layer acetate cloth is coated with adhesive to fill the gaps in the fine pores of the double-layer acetate cloth, making the multi-strand wire bundle waterproof when wrapped; the adhesive is epoxy resin adhesive or polyurethane adhesive.

[0053] The adhesive can effectively fill the pores and gaps on the double-layer acetate fabric, forming a continuous waterproof membrane. This prevents moisture from seeping into the wire harness through the tiny pores of the fabric. Through the sealing effect of the adhesive, the double-layer acetate fabric can better perform its waterproof function and improve the waterproof rating of the cable.

[0054] The soft silicone component 4 and soft silicone component 5 are disposed at both ends of the cable 3. Each of the soft silicone component 4 and soft silicone component 5 has a through hole in its center for the cable 3 to pass through. The cable 3 passes through the through hole. The soft silicone component 4 and soft silicone component 5 are sealed to the double-layer acetate cloth via an adhesive layer, forming a sealed whole. This effectively prevents moisture from seeping in through the gaps between the soft silicone component and the double-layer acetate cloth, providing a good seal and ensuring the waterproof performance of the cable 3 connection. The adhesive layer is silicone sealant. The outer shell 1 and inner shell 2 are provided with contoured grooves 101 and 201 that match the outer contours of the soft silicone component 4 and soft silicone component 25. The annular soft silicone ring 6 is also installed at each of the contoured grooves 101 and 201. The soft silicone parts 4 and 5 are pressed into the contour grooves 101 and 201, respectively, ensuring a tight fit between their contact surfaces. The soft silicone material has good elasticity, allowing it to adapt to deformation and external forces. When subjected to external pressure or impact, the soft silicone parts 4 and 5 undergo elastic deformation, pressing themselves into the contour grooves 101 and 201. When pressed into these grooves, the contact surfaces create a tight fit, further enhancing the sealing effect and effectively preventing moisture from seeping in through gaps between the soft silicone parts and the outer shell 1 and inner shell 2. This ensures the sealing performance of the entire waterproof structure and guarantees the waterproof performance of the equipment in harsh environments.

[0055] Furthermore, the outer shell 1 and the inner shell 2 are detachably connected by a snap-fit ​​mechanism. The outer shell 1 is provided with a buckle, and correspondingly, the inner shell 2 is provided with a slot that matches the buckle, making disassembly and assembly convenient.

[0056] Furthermore, both the outer shell 1 and the inner shell 2 are L-shaped, the first molding groove 101 is provided on the horizontal part of the outer shell 1, and the second molding groove 201 is provided on the vertical part of the inner shell 2.

[0057] This invention utilizes double-layer acetate cloth coated with adhesive to wrap multi-strand wire harnesses: The multi-strand wire harnesses are wrapped in double-layer acetate cloth, and adhesive is applied to the cloth to fill the gaps in the fine pores, forming a unified cable and thus achieving waterproofing for the multi-strand wire harnesses. This design not only improves the stability and reliability of the waterproofing effect but also enhances the overall structural strength of the cable.

[0058] This invention utilizes the elastic deformation of soft silicone to pass the wire harness through it. After the soft silicone tightens the wire harness, adhesive is applied to seal the soft silicone against the acetate cloth, achieving waterproofing. By leveraging the elastic deformation of the soft silicone to pass the wire harness through it, and then applying adhesive to tighten the wire harness, a seal is formed between the soft silicone and the acetate cloth, further enhancing the waterproof performance. This design not only improves the waterproofing effect but also reduces the amount of adhesive used, lowering the risk of waterproofing problems caused by incomplete adhesive curing.

[0059] This invention utilizes the soft elasticity of silicone to achieve a tight fit with the contoured groove of the housing, thus providing waterproofing. This design not only improves the waterproofing effect but also enhances the connection stability between the cable and the housing, extending the service life of the equipment.

[0060] This invention achieves a high level of waterproofing by setting an annular soft silicone ring at the rotating connection between rotating component one and rotating component two, and by squeezing and sealing the fixed side and rotating side of the annular soft silicone ring to achieve an airtightness test at a certain air pressure.

[0061] The rotating side of the annular soft silicone ring has multiple spaced annular ribs. These ribs make line contact with the rotating parts, which significantly reduces friction during rotation compared to traditional surface contact sealing. This low-friction design makes the rotating parts more flexible and smooth during relative movement, reducing problems such as poor rotation or component wear caused by excessive friction.

[0062] The rotating side uses multiple ribs to reduce friction during rotation. On the fixed side, a rubber ring is used to tighten the rotating component, increasing friction. This ensures that the annular silicone ring will not deform due to simultaneous pressure from the inner and outer walls during rotation, preventing uneven pressure that could lead to waterproofing failure.

[0063] The annular silicone ring, with its inner and outer walls, can be designed so that either side is designated as the fixed side and the other as the rotating side. This greatly improves versatility and adaptability, meeting the waterproof sealing requirements of different equipment and combinations of rotating components.

[0064] The waterproof rotating structure of this invention is suitable for a variety of equipment that needs to operate in harsh environments, such as outdoor security monitoring equipment, measuring instruments, and industrial automation equipment, and has wide applicability and promotional value.
