Description

Technical Field

[0001] The invention relates to a conductive slip ring, in particular to a conductive slip ring with a brush wire pressure regulating function. Background Art

[0002] In the conductive slip ring products, the pressure between the brush wire and the conductive ring is the key parameter. The pressure affects the reliability, usage scenarios, lifespan, etc. of the conductive slip ring products, as follows: (1) The pressure between the brush wire and the conductive ring is too high, and the contact reliability between the brush wire and the conductive ring will be improved. In the scene of high vibration and high impact level, the contact stability between the brush wire and the conductive ring is ensured by the large pressure between the brush wire and the conductive ring, but it will cause serious wear of the contact part between the brush wire and the conductive ring, resulting in a reduction in product life. Therefore, the conductive slip ring structure with a relatively large pressure between the brush wire and the conductive ring is suitable for scenes that need to withstand high vibration and high impact levels; (2) The pressure between the brush wire and the conductive ring is relatively small, and the wear of the contact part between the brush wire and the conductive ring will be reduced, which can extend the service life of the product, but the vibration and impact resistance will be reduced. In a vibration and impact environment, the brush wire may detach from the conductive ring, resulting in interruption of signal or current transmission and unstable signal or current transmission. Therefore, the conductive slip ring structure with a relatively small pressure between the brush wire and the conductive ring is suitable for scenarios with long service life but low vibration and impact levels.

[0003] The structure of the commonly used conductive slip rings at present is mainly an integrated structure, that is, the product is an integral structure. The commonly used conductive slip rings currently available usually include fixed end caps, a shell arranged between the end caps, a support frame fixed in the shell, a mounting plate component arranged on the support frame, a brush wire system on the mounting plate component, and a rotating shaft rotatably arranged on the support frame, and conductive rings distributed on the rotating shaft. Adjacent conductive rings are separated by insulating rings, and the brush wires on the brush wire system are in sliding contact with the conductive rings, and there is a certain pressure between the brush wires and the conductive rings. The rotating shaft is rotatably arranged on the support frame through bearings. When the conductive slip ring is working, the end cap is fixed to the stationary end, the rotating shaft rotates with the rotating component, and the brush wires on the brush wire system are in sliding contact with the conductive rings on the rotating shaft to achieve stable transmission of current and signals. After the conductive slip ring product is assembled, the positional relationship between the brush wire and the rotating shaft is fixed and cannot be adjusted. Therefore, the pressure between the brush wire and the conductive ring cannot be adjusted.

[0004] For example, in the patent with the announcement number "CN206332312U" and the invention name "A conductive slip ring with a V-groove copper ring", the conductive slip ring includes a stator, a rotor, a bearing, a housing, an insulating spacer, a brush plate, and a conductive ring. The stator is connected to the rotor through a bearing, and a brush plate is installed on the stator. The brush plate is provided with brush wires. The insulating spacer and the conductive ring are arranged on the rotor. The surface of the conductive ring is provided with V-grooves along the circumference. The insulating spacer separates the adjacent conductive rings, and the brush wires are slidably connected to the V-grooves of the conductive rings. Among them, the rotor is connected to the stator through a bearing, so the relative position of the two is fixed, and the pressure between the brush wires on the stator and the conductive ring on the rotor is fixed and cannot be adjusted.

[0005] Therefore, the product design of this type of conductive slip ring structure is customized. The pressure between the brush wire and the conductive ring in the customized conductive slip ring products is fixed, so the friction and vibration resistance between the conductive slip ring and the brush wire are relatively fixed. After the design and manufacturing are completed, it can only adapt to one use environment. If the conductive slip ring products are to be applied to different use environments, new conductive slip ring products need to be developed. Each time a product is developed, it is necessary to design parts such as support frames, mounting plate components and conductive rings, and adjust the pressure between the brush wire and the conductive ring to adapt to different use scenarios. The development cycle is cumbersome.

[0006] Among the products using conductive slip rings, electric rotary connectors are more common. Electric rotary connectors can be used to make electrical or signal connections between the fixed part of the equipment and the rotating part of the equipment. The current electric rotary connectors are custom-made and designed according to specific equipment. Once designed and manufactured, they can only be used on specific equipment. When it is necessary to make electrical or signal connections between the fixed part and the rotating part of other equipment, new electric rotary connectors can only be redesigned and manufactured. Therefore, the current conductive slip ring structure is fixed, resulting in the following main problems with the current customized electric rotary connectors: the conductive slip ring products are customized and fixed in structure, which are only applicable to a certain specific environment and cannot be expanded for use, which is not conducive to generalization and standardization; when the usage scenario is changed, it needs to be redesigned and produced, which is costly. Summary of the invention

[0007] In order to solve the technical problem that the pressure between the brush wire and the conductive ring in the above conductive slip ring cannot be adjusted, the present invention provides a conductive slip ring with a brush wire pressure adjustment function.

[0008] The purpose of the present invention is to be achieved by adopting the following technical scheme. According to the present invention, a conductive slip ring with a brush wire pressure adjustment function includes a mounting plate component provided with a brush wire and a shaft component provided with a conductive ring, the brush wire and the conductive ring are in sliding contact, the shaft component is coaxially arranged on the rotor end of the equipment, the mounting plate component is arranged on a fixed frame, the fixed frame can generate radial displacement relative to the fixed end of the equipment to adjust the pressure between the brush wire and the conductive ring, and after the fixed frame is moved into place, the fixed connection between the fixed frame and the fixed end of the equipment is realized by a locking member.

[0009] Compared with the prior art, the present invention is beneficial in that: The present invention adopts a split structure, and no parts such as a support frame are provided for fixing the position of the mounting plate component. The shaft component rotates with the rotor end of the equipment, and the mounting plate component is radially displaced and fixed on the fixed end of the equipment with the fixed frame, so as to realize the free adjustment of the radial distance between the mounting plate component and the shaft component, thereby realizing the free adjustment of the pressure between the brush wire and the conductive ring. When using the conductive slip ring, the position of the mounting plate component can be adjusted according to the actual vibration, impact level and required rotation life to adapt to different use environments and meet the requirements of universalization and standardization.

[0010] Furthermore, the fixing frame is provided with a fixing hole, which is a waist-shaped hole extending radially to allow the mounting plate component to produce radial displacement relative to the shaft component. A locking piece is passed through the fixing hole to connect the fixing frame to the fixed end of the device when the fixing frame is moved into place.

[0011] Compared with the prior art, the present invention is beneficial in that: Since the fixing hole is a waist-shaped hole, the position of the fixing frame on the fixed end of the device can be adjusted radially, thereby adjusting the radial distance between the fixing frame and the shaft component. After the adjustment, the locking piece can still be used to pass through the fixing hole for connection, thereby fixing the fixing frame on the fixed end of the device; within the length range of the fixing hole, the fixing frame can be adjusted to any position, thereby realizing free adjustment of the pressure between the brush wire and the conductive ring.

[0012] Furthermore, one of the fixed frame and the fixed end of the device is provided with a plurality of guide grooves extending in the radial direction, and the other is provided with a guide key slidably matched with the guide groove.

[0013] Compared with the prior art, the present invention is beneficial in that: When adjusting the position of the fixed frame, the sliding cooperation between the guide groove and the guide key can prevent the position of the fixed frame from being deflected, thereby preventing the fixed frame from blocking the structure combined with the locking piece on the fixed end of the device, thereby achieving accurate and fast connection.

[0014] Furthermore, one of the guide grooves is located on the symmetry plane of the fixed frame, and the mounting plate component is centrally arranged on the fixed frame so that the brush wire is symmetrically arranged on the fixed frame, and the radial projection of the guide groove on the symmetry plane and the corresponding guide key coincides with the rotation axis of the shaft component.

[0015] Compared with the prior art, the present invention is beneficial in that: When installing or adjusting the fixed frame, the guide groove and the guide key cooperate to enable the mounting plate component and the shaft component to be positioned and centered, which is convenient for alignment, so that the brush wires can be symmetrically distributed on both sides of the corresponding conductive ring, ensuring that the pressure between the conductive ring and the brush wires on both sides is equal.

[0016] Furthermore, a bell-shaped guide opening is provided at one end of the guide groove for guiding the guide key to be inserted into the guide groove.

[0017] Compared with the prior art, the present invention is beneficial in that: When the split conductive slip ring is installed on the equipment in a narrow space, the fixed frame can only be installed in the radial direction, and the guide key is inserted into the guide groove from the guide port. The guide port can guide the insertion of the guide key, and the fixed frame and the fixed end of the equipment can be guided and limited without the need for precise docking of the guide key and the guide groove.

[0018] Furthermore, an observation hole extending in the axial direction is provided through the fixed frame, and the observation hole and the guide groove or guide key provided on the fixed frame are distributed correspondingly in the radial direction.

[0019] Compared with the prior art, the present invention is beneficial in that: When installing the fixed frame in an environment with a relatively large operating space, the fixed frame cover can be directly placed on the side of the fixed end of the equipment. There is no need to install the fixed frame after radial alignment as in a narrow space, which can save installation time. At this time, the guide key or guide groove on the rear side of the fixed frame can be observed through the observation hole, and the guide key can be axially inserted into the guide groove, so that the fixed frame can be adjusted to the set position and fixed to the fixed end of the equipment.

[0020] Furthermore, the fixed frame includes a supporting plate and an adjusting plate which are perpendicular to each other, the supporting plate is located on one side of the shaft component, the mounting plate component is arranged on the supporting plate, and the fixing holes and guide grooves are arranged on the adjusting plate.

[0021] Compared with the prior art, the present invention is beneficial in that: The fixing frame has a simple structure and can simultaneously fix the mounting plate components and adjust the position relative to the fixed end of the equipment.

[0022] Furthermore, the fixed end of the device is provided with radially distributed scales, and the fixed frame is provided with a reference surface for axially aligning the scales, so that after the reference surface and the scales are axially aligned, there are corresponding pressure values ​​between the brush filaments and the conductive ring.

[0023] Compared with the prior art, the present invention is beneficial in that: When the user uses the conductive slip ring, the reference surface of the fixed frame can be aligned with the corresponding scale according to the pressure value requirements of the actual scene, so that the conductive slip ring can work normally under the corresponding pressure.

[0024] Furthermore, the shaft component has a plurality of conductive rings distributed in the axial direction, insulating rings are provided between adjacent conductive rings, and outer walls of the insulating rings are higher than outer walls of the conductive rings.

[0025] Compared with the prior art, the present invention is beneficial in that: The conductive rings are separated by insulating rings to avoid mutual interference between adjacent conductive rings. When adjusting the positions of the brush wires and the conductive rings, the insulating rings limit the brush wires to ensure that the brush wires are in contact with the corresponding conductive rings.

[0026] Furthermore, the fixed end of the equipment is rotatably connected to the rotor end of the equipment via a bearing.

[0027] Compared with the prior art, the present invention is beneficial in that: The shaft component is rotatably arranged on the fixed end of the equipment through the rotor end of the equipment, and the shaft component is stably rotated through the bearing. After adjusting the positions of the fixed frame, the mounting plate component and the fixed end of the equipment, the brush wire and the conductive ring are stably slidably matched.

[0028] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1 of the present invention is a conductive slip ring with a brush wire pressure adjustment function, as shown in FIG. Figures 1 to 4 As shown, hereinafter referred to as the conductive slip ring, the conductive slip ring comprises a device fixed end 1, a device rotor end 2, a fixed frame 4, a mounting plate component 5, and a shaft component 8.

[0033] A brush wire system is provided on the mounting plate component 5, and the brush wire system includes a plurality of brush wires 6. A plurality of conductive rings 9 are axially distributed on the shaft component 8, and adjacent conductive rings 9 are separated by insulating rings 10. The radial thickness of the insulating rings 10 is greater than the radial thickness of the conductive rings 9, so that the inner wall and outer wall of the insulating rings 10 are higher than the corresponding inner wall and outer wall of the conductive rings 9, thereby ensuring that the insulating rings 10 have a good insulating effect on the conductive rings 9 and preventing the brush wires 6 from detaching from the corresponding conductive rings 9. The shaft component 8 may also be provided with no insulating rings 10, and there is a certain distance between adjacent conductive rings 9 to ensure insulation, and an annular V-shaped groove is provided on the outer wall of the conductive ring 9 to keep the brush wires 6 in the V-shaped groove to prevent the brush wires 6 from detaching from the conductive rings 9. The brush wires 6 are in contact with the corresponding conductive rings 9, and there is a certain pressure between the brush wires 6 and the conductive rings 9. The mounting plate component 5 is located on one side of the circumferential outer wall of the shaft component 8. The brush wire system usually includes a plurality of brush wires 6 symmetrically arranged on both sides of the shaft component 8. The brush wires 6 arranged in pairs are V-shaped and clamped on both sides of the corresponding conductive ring 9. When designing the conductive slip ring and adjusting the pressure of the brush wires 6 on the conductive ring 9, the mounting plate component 5 is brought close to the shaft component 8, and the V-shaped paired brush wires 6 are stretched at a larger angle, and the brush wires 6 have a larger deformation. Under the action of the elastic restoring force of the brush wires 6, the brush wires 6 contact the conductive ring 9 with a larger force; the mounting plate component 5 is moved away from the shaft component 8, the angle between the V-shaped paired brush wires 6 is reduced, the deformation of the brush wires 6 is reduced, and the brush wires 6 contact the conductive ring 9 with a smaller force. It is defined that the mounting plate component 5 is close to or away from the shaft component 8 so that the direction of the pressure change between the brush wires 6 and the conductive ring 9 is radial, and the extension direction of the rotation axis of the shaft component 8 is axial.

[0034] The present invention improves the conventional one-piece conductive slip ring into a split conductive slip ring. After the present invention adopts the split structure, the mounting plate component 5 and the shaft component 8 can achieve relative displacement in the radial direction, so that the pressure between the brush wire 6 and the conductive ring 9 can be adjusted, so that the mounting plate component 5 is no longer just fixed relative to the support frame in the conventional conductive slip ring.

[0035] The device fixed end 1 is rotatably connected to the device rotor end 2. In this embodiment, the device fixed end 1 is connected to the device rotor end 2 through a bearing 3. The device fixed end 1 is used to connect to the fixed part of the device, and the device rotor end 2 is used to connect to the rotating part of the device. One end of the shaft component 8 is coaxially fixed with the device rotor end 2. In this embodiment, the device rotor end 2 is inserted and fixed in the center hole of the shaft component 8. The mounting plate component 5 is arranged on the fixed frame 4, and the position of the fixed frame 4 on the device fixed end 1 is adjustable and can be fixed, so that the mounting plate component 5 can be displaced in the radial direction relative to the shaft component 8. After moving into position, the position of the mounting plate component 5 is fixed, so that the radial distance between the mounting plate component 5 and the shaft component 8 can be adjusted, and the shaft component 8 can be rotated relative to the mounting plate component 5.

[0036] When the shaft component 8 rotates, the brush filaments 6 come into sliding contact with the corresponding conductive rings 9. When the pressure between the brush filaments 6 and the conductive rings 9 needs to be adjusted, the radial distance between the mounting plate component 5 and the shaft component 8 can be adjusted so that the bending angle of the brush filaments 6 relative to the conductive rings 9 changes elastically, thereby achieving pressure adjustment between the brush filaments 6 and the conductive rings 9.

[0037] In this embodiment, a fixing hole 401 is provided on the fixing frame 4, and a screw hole 102 is provided on the device fixing end 1. The screw 7 passes through the fixing hole 401 and is screwed into the screw hole 102 to achieve a fixed connection between the fixing frame 4 and the device fixing end 1.

[0038] The fixed frame 4 is L-shaped as a whole, and includes a support plate 404 and an adjustment plate 405 that are perpendicular to each other. The support plate 404 is parallel to the rotation axis of the shaft component 8 and is located on one side of the circumferential outer wall of the shaft component 8. The mounting plate component 5 is arranged on the surface of the support plate 404 facing the shaft component 8.

[0039] The adjustment plate 405 is used to connect with the device fixed end 1, and a fixing hole 401 is provided on the adjustment plate 405. The fixing hole 401 is a waist-shaped hole that passes through the adjustment plate 405. The length direction of the fixing hole 401 is perpendicular to the support plate 404, that is, it extends in the radial direction. In this embodiment, the fixing holes 401 are provided on both sides of the adjustment plate 405. The screw 7 passes through the fixing hole 401 and is screwed into the screw hole 102 of the device fixed end 1. The nut of the screw 7 is pressed on the adjustment plate 405, so that the adjustment plate 405 is fixed to the device fixed end 1, and then the fixing frame 4 is fixed to the device fixed end 1. Since the fixing hole 401 is a waist-shaped hole, the position of the fixing frame 4 can be adjusted in the radial direction, and then the radial distance between the fixing frame 4 and the shaft component 8 can be adjusted. After adjustment, the screw 7 can still be used to pass through the fixing hole 401 and be screwed into the screw hole 102 to fix the fixing frame 4 on the device fixed end 1; within the length range of the fixing hole 401, the fixing frame 4 can be adjusted to any position to achieve free adjustment of the pressure between the brush wire 6 and the conductive ring 9. When adjusting the position of the brush filament 6 , the insulating ring 10 or the conductive ring 9 limits the brush filament 6 to prevent the brush filament 6 from being separated from the corresponding conductive ring 9 .

[0040] A plurality of mutually parallel guide grooves 402 are distributed between the fixing holes 401 on both sides of the adjustment plate 405. The openings of the guide grooves 402 face the fixed end 1 of the device. The guide grooves 402 are long strip grooves, and the length direction of the guide grooves 402 is parallel to the length direction of the fixing holes 401. A guide key 101 that slidably cooperates with the guide groove 402 is provided on the fixed end 1 of the device. When adjusting the position of the fixed frame 4, the sliding cooperation between the guide groove 402 and the guide key 101 can prevent the position of the fixed frame 4 from being deflected, so as to prevent the adjustment plate 405 from blocking the screw hole 102 of the fixed end 1 of the device, so that the screw 7 can be accurately and quickly screwed into the screw hole 102. In this embodiment, three guide grooves 402 are distributed between the fixing holes 401 on both sides of the adjustment plate 405, wherein a guide groove 402 is set on the symmetric plane of the adjustment plate 405 (i.e., the symmetric plane of the fixed frame 4), and the radial projection of the guide groove 402 on the symmetric plane and the corresponding guide key 101 falls on the rotation axis of the shaft component 8, and the mounting plate component 5 and the fixed frame 4 are positioned and centered, so that the brush wire 6 on the mounting plate component 5 is symmetrically arranged on the fixed frame 4. When installing or adjusting the fixed frame 4, the guide groove 402 in the middle position cooperates with the corresponding guide key 101, so that the fixed frame 4 and the shaft component 8 are positioned and centered, and then the mounting plate component 5 and the shaft component 8 are positioned and centered, which is convenient for alignment, so that the brush wire 6 can be symmetrically distributed on both sides of the corresponding conductive ring 9, ensuring that the pressure between the conductive ring 9 and the brush wire 6 on both sides is equal.

[0041] In order to install the fixed frame 4 in a narrow space, the end of the guide groove 402 close to the shaft component 8 penetrates to the side wall of the adjustment plate 405 and forms a guide opening 406. The guide opening 406 is shaped like a trumpet mouth, and the width of the guide opening 406 gradually increases in the direction close to the shaft component 8. When the split conductive slip ring is installed on the equipment in a narrow space, the fixed frame 4 can only be installed close to the shaft component 8 in the radial direction, and the guide key 101 is inserted into the guide groove 402 from the guide port 406. The guide port 406 can guide the insertion of the guide key 101. There is no need for the guide key 101 to be precisely docked with the guide groove 402. The fixed frame 4 can be guided and limited on the fixed end 1 of the equipment, and then the distance between the fixed frame 4 and the shaft component 8 is adjusted according to the pressure set between the brush wire 6 and the conductive ring 9. Due to the guiding effect between the guide key 101 and the guide groove 402, during the adjustment process, the projection of the screw hole 102 on the fixed end 1 of the equipment on the adjustment plate 405 always falls within the fixing hole 401. After the fixed frame 4 is adjusted into place, the screw 7 can be directly passed through the fixing hole 401 and screwed into the screw hole 102 to fix the fixed frame 4 to the fixed end 1 of the equipment. The guide opening 406 can also be set at the end of the guide groove 402 away from the shaft component 8 and pass through the corresponding side wall of the adjustment plate 405. At this time, the fixed frame 4 can be radially installed first, the guide key 101 can be inserted into the guide groove 402 from one side of the guide opening 406, and then the shaft component 8 can be installed.

[0042] An observation hole 403 is provided at the bottom of one end of the guide groove 402 away from the shaft component 8, and the observation hole 403 axially penetrates the adjustment plate 405. When the fixed frame 4 is installed in an environment with a relatively large operating space, the adjustment plate 405 can be directly covered on the side of the fixed end 1 of the device, and there is no need to install the fixed frame 4 after aligning the guide key 101 radially in a narrow space, which can save installation time. At this time, the guide key 101 on the rear side of the adjustment plate 405 can be observed through the observation hole 403, and the guide key 101 is aligned with the observation hole 403, and then the guide key 101 is axially inserted into the guide groove 402, and then the fixed frame 4 is adjusted to the set position, and the fixed frame 4 is fixed to the fixed end 1 of the device. The observation hole 403 can also be set at other positions of the guide groove 402 or at other positions of the adjustment plate 405, as long as the guide key 101 can be observed through the observation hole 403 and the guide key 101 can be aligned with the guide groove 402.

[0043] In order to facilitate users to accurately adjust the pressure of the brush wire 6 on the conductive ring 9 in different scenarios, after the conductive slip ring is assembled and the position of the fixed frame 4 is determined, the existing theory is used to calculate the actual pressure of the brush wire 6 on the conductive ring 9, and the surface of the adjustment plate 405 away from the side of the shaft component 8 is the reference surface 407. The projection of the reference surface 407 in the axial direction falls on the fixed end 1 of the device, and a scale 11 is set at the projection position to mark the corresponding pressure value; in this way, the position of the fixed frame 4 is continuously adjusted, and the actual pressure of the brush wire 6 on the conductive ring 9 at different positions is calculated, and the corresponding scale 11 is marked at the corresponding position of the fixed end 1 of the device. When the user uses the conductive slip ring, the reference surface 407 of the fixed frame 4 can be aligned with the corresponding scale 11 according to the requirements of the pressure value in the actual scenario, so that the conductive slip ring can work normally under the corresponding pressure.

[0044] The present invention adopts a split structure, and no parts such as a support frame are provided for fixing the position of the mounting plate component 5. The equipment fixed end 1 and the equipment rotor end 2 are rotatably connected through the bearing 3, and the shaft component 8 rotates with the equipment rotor end 2. The mounting plate component 5 is adjustable on the equipment fixed end 1 along with the fixed frame 4, so that the radial distance between the mounting plate component 5 and the shaft component 8 can be freely adjusted, thereby realizing the free adjustment of the pressure between the brush wire 6 and the conductive ring 9. When using the conductive slip ring, the position of the mounting plate component 5 can be adjusted according to the actual vibration and impact level and the required rotation life to adapt to different use environments and meet the requirements of universalization and standardization.

[0045] In the second embodiment of the conductive slip ring with a brush wire pressure adjustment function of the present invention, an improvement is made on the basis of the first embodiment. When the conductive slip ring is used to connect the fixed part and the rotating part in the equipment so that the fixed part of the equipment and the rotating part can be electrically connected or signal connected, the fixed end 1 of the equipment can be fixedly connected to the fixed part of the equipment, and the rotor end 2 of the equipment can be fixedly connected to the rotating part of the equipment, so that the fixed end 1 of the equipment and the rotor end 2 of the equipment can be relatively rotatable, and the bearing 3 is no longer required.

[0046] In the third embodiment of a conductive slip ring with a brush wire pressure adjustment function of the present invention, based on the first embodiment, the fixing hole 401 can be set as a circular hole, and a plurality of fixing holes 401 are distributed in the radial direction of the adjustment plate 405, each fixing hole 401 corresponds to a pressure value, and according to the use environment, one of the fixing holes 401 is aligned with the screw hole 102 of the fixed end 1 of the device, and then the screw 7 is used to pass through the fixing hole 401 and screwed into the screw hole 102 to achieve the fixation of the fixing frame 4 and the fixed end 1 of the device.

[0047] In the fourth embodiment of the conductive slip ring with brush wire pressure adjustment function of the present invention, on the basis of the first embodiment, the screw 7 can be replaced by a bolt, a circular through hole is set at the fixed end 1 of the device, and the bolt is passed through the fixing hole 401 and the circular through hole, and is screwed with the nut, so that the fixing frame 4 is fixedly set at the fixed end 1 of the device, or a nut is nested in the circular through hole, and the bolt is screwed into the nut after passing through the fixing hole 401. The bolt can also be replaced by other types of locking parts, such as a stud, the stud passes through the fixing hole 401 and the circular through hole, the two ends of the stud are respectively connected to the nut and the nut is tightened on the corresponding fixed end 1 of the device and the fixed frame 4, so that the fixed frame 4 is fixedly set at the fixed end 1 of the device.

[0048] In the fifth embodiment of the conductive slip ring with brush wire pressure adjustment function of the present invention, on the basis of the first embodiment, the guide groove 402 can be set at the fixed end 1 of the device, and the guide key 101 can be set on the adjustment plate 405 of the fixed frame 4. The guide groove 402 extends radially, and a guide port 406 is provided at the end of the guide groove 402. The guide port 406 is used to guide the guide key 101 to be inserted into the guide groove 402 when the fixed frame 4 is installed in a narrow space. The observation hole 403 is set on the adjustment plate 405 and is distributed in a radial direction corresponding to the guide key 101.
