[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-8 , the present invention provides a technical solution: a conductive slip ring with a self-lubricating structure, according to Figure 1 , Figure 2 and Figure 8As shown in the figure, a self-lubricating coating 101 is coated on the outer side of the slip ring body 1. The self-lubricating coating 101 is composed of a solid lubricant and a binder, and the solid lubricant is made of polytetrafluoroethylene material. Through the self-lubricating coating 101, during the relative movement between the electric brush head 7044 and the slip ring body 1, due to the continuous release of the solid lubricant, an extremely thin lubricating film is formed between the two, effectively reducing the rotational friction coefficient between the electric brush head 7044 and the slip ring body 1, reducing wear, and thus prolonging the service life of the conductive slip ring. Both sides of the slip ring body 1 are connected to the inner sides of the corresponding positioning bearings 2 through the first insulating sleeves. At the same time, the outer sides of the two positioning bearings 2 are connected to both sides inside the protective housing 3. The inside of the slip ring body 1 is connected to the main shaft 4 through the second insulating sleeve, and one end of the main shaft 4 passes through one side of the slip ring body 1 and extends to the outside of one end of the protective housing 3. The protective housing 3 is of a rectangular structure, and the first positioning seat 5 and the second positioning seat 6 are respectively connected to both sides of the protective housing 3 through fixing screws. At the same time, insulating gaskets are provided at the joints where the first positioning seat 5 and the second positioning seat 6 are in contact with the side of the protective housing 3. Both the first positioning seat 5 and the second positioning seat 6 are made of stainless steel, and an insulating and wear-resistant coating is coated on the inner side of the through-hole opened in the middle of the second positioning seat 6. At the same time, the position of the through-hole is correspondingly set with the position of the outer side of one end of the main shaft 4. A temperature detector 301 is provided at the upper end of the front surface of the protective housing 3. Through the temperature detector 301, it is convenient to monitor the temperature inside the protective housing 3, prevent the temperature from being too high due to long-term use, causing failures and affecting the use. And a dust-proof ventilation net plate 302 is provided in the middle of the front surface of the protective housing 3. Through the dust-proof ventilation net plate 302, the heat generated during the relative movement between the electric brush head 7044 and the slip ring body 1 is dissipated.

[0030] To further illustrate, a plurality of ventilation holes 501 are equidistantly opened in the middle of the first positioning seat 5, and the ventilation holes 501 are arranged in a ring shape. At the same time, a cooling fan 9 is provided in the middle of the outer side of the first positioning seat 5. A protective net frame 10 is provided on the outer side of the cooling fan 9, and the protective net frame 10 is magnetically connected to the outer side of the first positioning seat 5 through a magnetic seat 11. At the same time, the protective net frame 10 is located outside the ventilation holes 501. Through the cooling fan 9, the air circulation rate can be increased, and the heat dissipation effect can be improved.

[0031] To further illustrate, the main shaft 4 is made of a high-strength and corrosion-resistant metal material to improve the stable mechanical properties of the main shaft 4 during use. An external thread is provided on the outer side of one end of the main shaft 4 located inside the slip ring body 1, and the external thread is threadedly connected to the internal thread opened in the second insulating sleeve. The other end of the main shaft 4 is of a hollow structure, and an internal thread is opened inside the other end of the main shaft 4. At the same time, a plurality of mounting holes are equidistantly opened on the outer side of the other end of the main shaft 4, which is convenient for connecting and fixing the main shaft 4 to the slip ring body 1 and other devices.

[0032] During use, the temperature detector 301 monitors the temperature inside the protective housing 3. When the temperature is too high, the cooling fan 9 is started, allowing external air to enter the inside of the protective housing 3 through the dust-proof ventilation mesh plate 302, and discharging the heat generated by the rotational friction between the electric brush head 7044 and the slip ring body 1 through the ventilation holes 501, thereby quickly dissipating heat and improving the practicality of use.

Connecting rods 7033 are slidably connected inside both sides of the top seat 7031. The lower ends of the two connecting rods 7033 pass through the sealing seat 701 and are detachably connected to the lower ends of both sides of the brush assembly 704. At the same time, the tops of the two connecting rods 7033 pass through a positioning frame 7034 provided at the upper end of the sealing seat 701 and extend above the positioning frame 7034. A clamping sleeve 7035 is sleeved on the outer side of the upper end of the connecting rod 7033. The clamping sleeve 7035 is made of T-shaped elastic rubber. At the same time, the clamping sleeve 7035 is snap-connected to a positioning hole opened on the positioning frame 7034. Through the clamping sleeve 7035, it is convenient to fixedly connect the connecting rod 7033 to the positioning frame 7034, making the connecting rod 7033 not easy to move and improving the stability of the connecting rod 7033 during use. And the lower bottom of the support adjustment assembly 703 passes through the sealing seat 701 and is connected to the corresponding brush assembly 704. The brush assembly 704 includes a brush seat 7041, a metal connecting piece 7043, and a brush head 7044. The two sides of the brush seat 7041 are connected to the brush head 7044 through the metal connecting piece 7043.

Adjusting seats 7042 are provided at the bottom of one end of the metal connecting piece 7043 on both sides of the brush seat 7041. The adjusting seats 7042 adopt an eccentric wheel structure. By rotating the eccentric wheel, it is convenient to connect and support the metal connecting piece 7043, making the unfolding arc of the metal connecting piece 7043 increase or decrease, so that the brush head 7044 can better contact the outer side of the slip ring body 1. At the same time, an insulating seat 7045 is provided on the outer side of the lower end of the metal connecting piece 7043. The upper end of the insulating seat 7045 is detachably connected to the bottom of the corresponding connecting rod 7033. Through the connecting rod 7033 and the insulating seat 7045, it is convenient to position the placement position of the brush head 7044 and improve the stability of the contact between the brush head 7044 and the slip ring body 1.

[0034] During use, rotate the adjustment seat 7042 to make the arc of the unfolded metal connecting piece 7043 the same as the arc on the outer side of the slip ring body 1. Then, by pushing the connecting rod 7033, the insulating seat 7045 drives the lower end of the metal connecting piece 7043 to move synchronously, bringing the electric brush head 7044 into contact with and fitting onto the outer side of the slip ring body 1. Next, move the engaging sleeve 7035 to fixedly connect the connecting rod 7033 to the positioning frame 7034. Finally, rotate the mounting bolt to install and fix the sealing seat 701 on the protective housing 3, thus completing the installation of the brush mechanism 7.

Through the liquid filling head 804, it is convenient to add lubricating grease into the liquid storage box 801 to ensure an adequate stock of lubricating grease. At the same time, the liquid filling head 804 passes through the mounting seat 803 and is connected to the liquid storage box 801. A plurality of diversion components 802 are equidistantly arranged at the upper end of the liquid storage box 801. The diversion component 802 includes a storage cylinder 8021, and a metering liquid pumping pump 8022 is snap-connected in the middle of the storage cylinder 8021.

A liquid inlet 8024 is provided at the lower end of the drainage pipe 8023. And a seal 8025 is provided at the connection between the drainage pipe 8023 and the liquid storage box 801. Through the seal 8025, the sealing performance at the connection between the drainage pipe 8023 and the liquid storage box 801 is improved, preventing the lubricating grease from overflowing through the gap. The top of the metering liquid pumping pump 8022 is connected to an oil storage cotton block 8026, and the bottom of the lower end of the oil storage cotton block 8026 is in contact with the top of the storage cylinder 8021.

[0036] During use, the lubricating grease stored in the liquid storage box 801 is pumped by the metering liquid pumping pump 8022 into the drainage pipe 8023 through the liquid inlet 8024. Then, the lubricating grease is adsorbed by the oil storage cotton block 8026. When the slip ring body 1 rotates, the lubricating grease on the oil storage cotton block 8026 adheres to the outer side of the slip ring body 1, further enhancing the lubrication effect and providing additional lubrication protection for the electric brush head 7044 and the slip ring body 1.
