[0002] Chinese patent document CN221262917U discloses a waterproof device for a conductive slip ring, including a conductive slip ring body with a hollow top. A wire outlet port is installed on the top sidewall of the conductive slip ring body. A waterproof plate is installed on the top of the conductive slip ring body, with the waterproof plate sloping downwards from the center to both ends. The conductive slip ring body and the waterproof plate are detachably connected. Several connecting grooves are formed on the inner sidewall of the top of the conductive slip ring body, and a spring is installed in each groove. One end of the spring is installed at the bottom of the connecting groove, and a locking block is fixed to the other end of the spring. Both the upper and lower ends of the locking block are sloping. The bottom of the waterproof plate engages with the top of the conductive slip ring body, and a locking groove is formed on the bottom sidewall of the waterproof plate to cooperate with the locking block. This invention solves the problem that existing conductive slip rings have poor waterproof performance and cannot meet the requirements of harsh working environments.
[0003] After investigation and analysis, the patent has the following drawbacks in actual use:
[0004] When the device is waterproofing, it isolates water from the conductive slip ring through a waterproof plate. However, moisture in the air can still affect the internal structure of the conductive slip ring, potentially causing short circuits, corrosion, and reduced insulation in the conductive parts, thus affecting the normal operation of the slip ring.
[0005] In summary, this application proposes a waterproof device for a conductive slip ring to solve the aforementioned problems. Utility Model Content
[0006] The purpose of this invention is to provide a waterproof device for a conductive slip ring, which solves the problem that when the device is used for waterproofing, the water is isolated from the conductive slip ring by the waterproof plate, but the moisture in the air can still affect the internal structure of the conductive slip ring, which may cause problems such as short circuits, corrosion, and reduced insulation of the conductive parts, thereby affecting the normal operation of the slip ring.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof device for a conductive slip ring, comprising a conductive slip ring body and a waterproof and moisture-proof component. The waterproof and moisture-proof component is located on the outer wall of the conductive slip ring body. The waterproof and moisture-proof component includes an installation strip, a retaining plate, a connecting frame, a pull-out plate, a desiccant, a first rubber plate, a first snap-fit groove, a second rubber plate, and a second snap-fit groove. The outer wall of the first rubber plate has a second snap-fit groove, and the inner wall of the first rubber plate has a first snap-fit groove. The second rubber plate is snap-fitted and installed inside the first snap-fit groove.
[0008] Preferably, the outer wall of the conductive slip ring body is provided with a lower cover and an upper cover. One end of the upper cover is fixedly connected with an external threaded post, and one end of the lower cover is provided with an internal thread. The upper cover is threadedly connected to the lower cover through the external threaded post and the internal thread.
[0009] Preferably, the lower cover and the upper cover are sleeved and installed on the outer wall of the conductive slip ring body, and the inner walls of the lower cover and the upper cover do not contact the conductive slip ring body.
[0010] Preferably, the inner walls of both the lower and upper covers are fixedly connected to multiple sets of mounting strips arranged in a circular array. A retaining plate is snapped between every two adjacent sets of mounting strips. A connecting frame is fixedly connected to the retaining plate, and a pull-out plate is slidably mounted on the connecting frame. A desiccant is placed inside the retaining plate. Through the combined use of the mounting strips, retaining plate, connecting frame, pull-out plate, desiccant, rubber plate one, retaining groove one, rubber plate two, and retaining groove two, moisture or humidity can be effectively prevented from penetrating into the slip ring. This is especially helpful in humid or rainy environments, as it helps to prevent moisture from damaging the internal electronic components of the conductive slip ring. Furthermore, the desiccant effectively absorbs excess moisture and humidity inside the conductive slip ring, reducing the impact of ambient humidity on the internal components. Even if the waterproofing device fails to completely prevent moisture from entering, the desiccant can still play a supplementary role, preventing excessive moisture accumulation inside the conductive slip ring.
[0011] Preferably, the number of rubber sheet one and rubber sheet two is two sets distributed vertically, and the two sets of rubber sheet one are respectively snapped and installed at one end of the lower cover and the upper cover through snap-fit groove two.
[0012] Preferably, the card plate has multiple sets of ventilation holes to facilitate the absorption of moisture inside the lower and upper covers, and the rubber plate does not come into contact with the rotating shaft of the conductive slip ring body.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The waterproof device of this conductive slip ring, through the combined use of the mounting strip, clamping plate, connecting frame, pull-out plate, desiccant, rubber plate one, clamping groove one, rubber plate two, and clamping groove two, can effectively prevent moisture or humidity from penetrating into the interior of the slip ring. Especially in humid or rainy environments, this helps to prevent moisture from damaging the internal electronic components of the conductive slip ring. Furthermore, the desiccant can effectively absorb excess moisture and humidity inside the conductive slip ring, reducing the impact of environmental humidity on the internal components of the slip ring. Even if the waterproof device fails to completely prevent moisture from entering, the desiccant can still play a supplementary role, preventing excessive moisture accumulation inside the conductive slip ring body.

[0020] Please see Figure 1-3This utility model provides a technical solution: a waterproof device for a conductive slip ring, comprising a conductive slip ring body 1 and a waterproof and moisture-proof component. The outer wall of the conductive slip ring body 1 is provided with a lower cover 2 and an upper cover 3. One end of the upper cover 3 is fixedly connected to an external threaded post 4, and one end of the lower cover 2 is provided with an internal thread. The upper cover 3 is threadedly connected to the lower cover 2 through the external threaded post 4 and the internal thread. The lower cover 2 and the upper cover 3 are sleeved and installed on the outer wall of the conductive slip ring body 1, and the inner walls of the lower cover 2 and the upper cover 3 do not contact the conductive slip ring body 1. The waterproof and moisture-proof component is located on the outer wall of the conductive slip ring body 1 and includes an installation strip 5, a retaining plate 6, a connecting frame 7, a pull-out plate 8, a desiccant 9, a rubber sheet 10, and a retaining groove 1. 1. Rubber plate 2 12 and snap-fit groove 2 13: The outer wall of rubber plate 10 has snap-fit groove 2 13, and the inner wall of rubber plate 10 has snap-fit groove 11. Rubber plate 2 12 is snap-fitted into the inside of snap-fit groove 11. Multiple sets of mounting strips 5 are fixedly connected to the inner walls of the lower cover 2 and the upper cover 3 in a circular array. A snap-fit plate 6 is snap-fitted between every two adjacent sets of mounting strips 5. A connecting frame 7 is fixedly connected to the snap-fit plate 6, and a pull-out plate 8 is slidably installed on the connecting frame 7. A desiccant 9 is placed inside the snap-fit plate 6. In use, the lower cover 2 and the upper cover 3 are fitted onto the outer wall of the conductive slip ring body 1 until one end of the lower cover 2 contacts the external threaded post 4. Then, the upper cover 3 is continuously rotated. As the device rotates continuously, it gradually comes into contact with the lower cover 2. Then, the rubber plate 10 is lifted and aligned with the other end of the lower cover 2 and upper cover 3, allowing the snap-fit groove 13 on the rubber plate 10 to engage with one end of the lower cover 2 and upper cover 3. Next, the rubber plate 12 is lifted and aligned with the rubber plate 10, allowing its outer wall to fit into the snap-fit groove 11 on the rubber plate 10. When the desiccant 9 needs to be replaced, the lower cover 2 and upper cover 3 are manually unscrewed and pulled out. Then, the snap-fit plate 6 is manually pulled out, causing the connecting frame 7, pull-out plate 8, and desiccant 9 to move outwards. Finally, the pull-out plate 8 is manually pulled upwards, disengaging it from the connection. Next, remove and replace the desiccant 9. Through the combined use of mounting strip 5, clamping plate 6, connecting frame 7, pull-out plate 8, desiccant 9, rubber plate 10, snap-fit groove 11, rubber plate 2 12, and snap-fit groove 2 13, moisture or humidity can be effectively prevented from penetrating into the slip ring, especially in humid or rainy environments. This helps to prevent moisture from damaging the internal electronic components of the conductive slip ring. Furthermore, the desiccant 9 can effectively absorb excess moisture and humidity inside the conductive slip ring, reducing the impact of ambient humidity on the internal components of the slip ring. Even if the waterproof device fails to completely prevent moisture from entering, the desiccant can still play a supplementary role, preventing excessive moisture accumulation inside the conductive slip ring body 1.
[0021] Furthermore, the number of rubber plates 10 and 12 is two sets distributed vertically. The two sets of rubber plates 10 are respectively snapped and installed at one end of the lower cover 2 and the upper cover 3 through the snap-fit groove 13. Multiple sets of ventilation holes are opened on the snap-fit plate 6 to facilitate the absorption of moisture inside the lower cover 2 and the upper cover 3. The rubber plate 12 does not contact the rotating shaft of the conductive slip ring body 1.
[0022] Working principle: In use, the lower cover 2 and the upper cover 3 are fitted onto the outer wall of the conductive slip ring body 1 until one end of the lower cover 2 contacts the external threaded post 4. Then, the upper cover 3 is rotated continuously, and the upper cover 3 gradually fits into the lower cover 2 through continuous rotation. Next, the rubber plate 10 is lifted and aligned with the other end of the lower cover 2 and the upper cover 3, so that the snap-fit groove 13 on the rubber plate 10 snaps into one end of the lower cover 2 and the upper cover 3. Then, the rubber plate 12 is lifted and aligned with the other end of the lower cover 2 and the upper cover 3. Rubber sheet 10 is fitted onto the rubber sheet 2, and the outer wall of rubber sheet 12 is fitted into the snap-fit groove 11 on rubber sheet 10 for installation. When the desiccant 9 needs to be replaced, manually unscrew the lower cover 2 and the upper cover 3, pull out the lower cover 2 and the upper cover 3, then manually pull out the snap plate 6. The snap plate 6 drives the connecting frame 7, the pull plate 8 and the desiccant 9 to move outward. Then manually pull the pull plate 8 upward so that the pull plate 8 is separated from the connecting frame 7. Then take out the desiccant 9 and replace it.
[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
