This puts forward a requirement for the sealing performance of slip ring. If the sealing performance is poor, the internal part of the product will be short-circuited and contaminated, which seriously affects the electrical conductivity and service life. Therefore, a reinforced slip ring sealing structure is urgently needed. SUMMARY

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be further described in detail below:

[0022] This utility model discloses an enhanced slip ring sealing structure, such as... Figure 1 , Figure 2 As shown, this utility model discloses an enhanced slip ring sealing structure, comprising a housing 1 and a rotor 11. The rotor 11 is rotatably connected to the inside of the housing 1 via bearings. The housing 1 contains several stators 12 that contact the rotor 11. An elastic component is disposed inside the top wall of the housing 1. A sliding seat 2 is slidably connected to the top wall of the housing 1 via the elastic component. A sealing ring 3 is disposed at the bottom of the sliding seat 2, and the sealing ring 3 contacts the rotor 11. A pressure rod 4 is rotatably connected to the top of the housing 1, which can drive the sliding seat 2 to move towards the rotor 11. A locking component for locking the position of the pressure rod 4 is disposed on the top of the housing 1. A rubber ring 5 for sealing the gap between the sliding seat 2 and the top wall of the housing 1 is disposed on the top of the housing 1. In this embodiment, the positional relationship between the sliding seat 2, the rotor 11, and the pressure rod 4 is as follows: Figure 2 As shown. A through hole is provided at the top of the sliding seat 2, through which the top of the rotor 11 extends beyond the housing 1. The pressure rod 4 exerts downward pressure on the sliding seat 2, causing the sealing ring 3 at the bottom of the sliding seat 2 to press against the top of the rotor 11, thus achieving a sealing effect and preventing gas or liquid from entering the slip ring and affecting its conductivity and service life. The rubber ring 5 is positioned as shown... Figure 2 As shown, the function of the rubber ring 5 is to seal the gap between the sliding seat 2 and the top wall of the housing 1. The rubber ring 5 is a thin circular ring. The outer edge of the rubber ring 5 is fixedly connected to the top of the housing 1, and the inner edge of the rubber ring 5 is fixedly connected to the top of the sliding seat 2. Due to the material properties of the rubber ring 5 itself, it can move with the sliding seat 2 without breaking, and the rubber ring 5 itself is waterproof, thus sealing the gap between the sliding seat 2 and the top wall of the housing 1. Through the cooperation of the rubber ring 5 and the sealing ring 3, an excellent sealing effect is achieved inside the slip ring.

[0023] By incorporating an elastic component, a pressure rod 4, and a sealing ring 3, the pressure rod 4 drives the sliding seat 2 towards the rotor 11, ensuring tight contact between the sealing ring 3 and the rotor 11 and enhancing the sealing tightness. A locking component allows the pressure rod 4 to be easily locked and unlocked, facilitating the installation, adjustment, and maintenance of the sealing structure. It is worth noting that the lower side of the sealing ring 3 presses against the top of the rotor 11 to achieve a seal. Excessive pressure can affect the rotation of the rotor 11. Therefore, adjusting the position of the pressure rod 4 controls the pressure between the sealing ring 3 and the rotor 11, ensuring that the rotor 11 can rotate while the sealing ring 3 provides a seal. Furthermore, after prolonged use, the sealing ring 3 will wear down, reducing its sealing performance. Adjusting the position of the pressure rod 4 allows the sealing ring 3 to continue contacting the rotor 11, thus extending its service life. Preferably, the end face of the sealing ring 3 in contact with the rotor 11 has two sets of symmetrical serrations 31. The serration design reduces friction between the sealing ring 3 and the rotor 11 without compromising the sealing effect, resulting in smoother rotation of the rotor 11. Preferably, the top surface of the sliding seat 2 that contacts the rubber ring 5 is rounded. Preferably, the sealing ring 3 is made of polytetrafluoroethylene (PTFE).

[0024] like Figure 2 , Figure 3 , Figure 4 As shown, the elastic component includes a slide rod 61 and a lifting spring 62. A sliding groove 63 is formed inside the top wall of the housing 1, and the slide rod 61 is disposed within the sliding groove 63. A connecting part 21 is integrally formed on the outer side wall of the sliding seat 2. The sliding seat 2 is slidably connected to the slide rod 61 through the connecting part 21. One end of the lifting spring 62 is fixedly connected to the bottom of the connecting part 21, and the other end of the lifting spring 62 is fixedly connected to the bottom wall of the sliding groove 63. In this embodiment, the specific structure of the sliding seat 2 is as follows: Figure 3 As shown, the position of the sliding groove 63 is as follows Figure 2 As shown. The sliding groove 63 is circular, and a cylindrical sliding rod 61 is provided inside it. The connecting parts 21 on both sides of the sliding seat 2 are fan-shaped. The sliding rod 61 passes through the connecting parts 21, so that the sliding seat 2 can slide along the sliding rod 61. The lifting spring 62 is sleeved on the outside of the sliding rod 61. The lifting spring 62 can push the sliding seat 2 to move away from the rotor 11.

[0025] like Figure 5 , Figure 6As shown, the locking assembly includes a locking disc 71, a locking pin 72, and a locking spring 73. Two columns 74 are fixedly connected to the top of the housing 1. The pressure rod 4 is rotatably connected between the two columns 74. A locking disc 71 is disposed on the side wall of each column 74 near the pressure rod 4. The surface of the locking disc 71 is provided with several prisms 75. A receiving groove 76 is formed on the side wall of the pressure rod 4. A locking pin 72 is disposed inside the receiving groove 76. One end of the locking spring 73 is fixedly connected to the inner side wall of the receiving groove 76, and the other end of the locking spring 73 is fixedly connected to the locking pin 72. The locking pin 72 is L-shaped. A sliding groove 77 is formed at the top of the receiving groove 76, and the top of the locking pin 72 passes through the sliding groove 77 and extends beyond the sliding groove 77. In this embodiment, the shapes of the locking disc 71 and the locking pin 72 are as follows: Figure 5 , Figure 6 As shown, by setting a locking disc 71, a locking pin 72, and a locking spring 73, the end of the locking pin 72 can be engaged with the prism 75 on the surface of the locking disc 71, thereby fixing the angle of the pressure rod 4. Preferably, the cross-section of the prism 75 is triangular, and several prisms 75 are distributed in a circumferential array on the surface of the locking disc 71. The end of the locking pin 72 that contacts the prism 75 forms a driving inclined surface 721. The cross-section of the driving inclined surface 721 at the end of the locking pin 72 is a triangle that matches the prism 75. When the pressure rod 4 is pressed down to the sliding seat 2, the locking pin 72 will slide on the surface of the prism 75 and compress the locking spring 73. When the locking pin 72 reaches the next prism 75, it will pop out under the action of the locking spring 73 and engage with the next prism 75, so that the pressure rod 4 can be adjusted step by step.

[0026] The implementation principle of this utility model embodiment is as follows:

[0027] Press the sliding seat 2 downward with the pressure rod 4 so that the sealing ring 3 at the bottom of the sliding seat 2 comes into contact with the rotor 11. The pressure between the sealing ring 3 and the rotor 11 can be controlled by adjusting the angle of the pressure rod 4 so that the rotor 11 can still rotate in the sealed state. When the pressure rod 4 is pressed downward with the sliding seat 2, the locking pin 72 will slide on the surface of the prism 75 and compress the locking spring 73. When the locking pin 72 reaches the next prism 75, it will pop out under the action of the locking spring 73 and lock onto the next prism 75, so that the pressure rod 4 can be adjusted step by step.
