Description

A multi-loop conductive slip ring Technical Field

[0001] This utility model relates to the field of conductive slip ring technology, and in particular to a multi-loop conductive slip ring. Background Technology

[0002] Multi-loop conductive slip rings are precision electromechanical components used to realize multi-circuit electrical energy and signal transmission between rotating and stationary equipment. They are a special type of conductive slip ring (also known as slip ring or rotary joint) and have the following structure:

[0003] 1. Rotor section: The conductive ring is composed of multiple concentric metal rings and is the core component for realizing the conductivity function. The material is generally copper or other metals with good conductivity. Each ring is insulated from the others and corresponds to different channels to transmit current or signals. The shaft or rotor support is used to fix the conductive ring. The hollow structure in the middle can be fitted onto the shaft of the rotating equipment to achieve synchronous rotation with the equipment and provide mechanical support.

[0004] 2. Outer shell: Protects internal conductive rings, brushes and other components, provides mechanical support, and is generally made of metal (such as aluminum alloy) or engineering plastics, with a certain strength and protective performance;

[0005] 3. Fixing screws and screw holes: This is the structure for fixing the conductive slip ring.

[0006] When installing a conductive slip ring, its hollow structure allows it to be fitted onto the shaft of a rotating device. The fixing screw is then rotated to ensure a tight fit against the shaft surface, thus securing the slip ring. In practical applications, rotating equipment experiences continuous vibration, centrifugal force, and temperature changes, which can cause the fixing screw to loosen and rotate under these external forces. Loosening of the fixing screw can affect the normal operation of the equipment, and prolonged loosening may even cause the conductive slip ring to detach from the rotating device, leading to equipment failure. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this utility model provides a multi-loop conductive slip ring, which solves the technical problem that due to the complex working conditions such as continuous vibration, centrifugal force, and temperature changes generated during the operation of rotating equipment, the fixing screws are prone to loosening and rotation under the action of these external forces. When the fixing screws become loose, it will affect the normal operation of the equipment. Long-term loosening may also cause the conductive slip ring to fall off the rotating equipment, leading to equipment failure.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A multi-loop conductive slip ring includes a conductive slip ring body with four fixing screws threaded to its exterior. Each side of the conductive slip ring body corresponding to a fixing screw has a limiting mechanism to restrict the movement of the fixing screw. Each limiting mechanism includes a moving groove, a spring, a limiting bracket, and a limiting groove. The moving groove is located on the exterior of the conductive slip ring body, the spring is fixedly connected inside the moving groove, the end of the limiting bracket is fixedly connected to the exterior of the spring, and the limiting groove is located on the exterior of the limiting bracket. The head of the fixing screw is located inside the limiting groove. Each limiting bracket has a spring piece on its exterior for restricting the movement of the limiting bracket. Each limiting bracket has a deformation groove on its side corresponding to the spring piece, and one end of the spring piece is fixedly connected inside the deformation groove.

[0010] Preferably, each limiting frame has a limiting block fixedly installed on its upper surface to limit the position of the limiting frame, and each limiting block has an opening on its exterior.

[0011] Preferably, each movable slot has a fixed shaft installed inside, and a spring is movably sleeved on the outside of the fixed shaft. Each limit frame has a movable hole on its outside, and the limit frame is slidably connected to the outside of the fixed shaft through the movable hole. The fixed shaft serves as the support shaft for the spring and the limit frame, providing movement guidance.

[0012] Preferably, each fixed shaft has a bolt at its upper end for limiting the movement of the limit frame, and each fixed shaft has a threaded hole on one side corresponding to the bolt. The bolt is threaded into the inside of the threaded hole. Each limit groove has a receiving hole inside, which communicates with the inside of the moving hole. The bolt head is located inside the receiving hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When installing the fixing screw, first press down on the limit bracket to allow it to enter the moving groove. During this process, the spring is compressed, and the friction between the spring piece and the inner wall of the moving groove generates resistance, forming a temporary lock and keeping the limit bracket pressed down. When the fixing screw is turned to the appropriate position, move the limit bracket until the head of the fixing screw is inside the limit groove. At this point, the fixing screw is restricted and cannot rotate, thus ensuring the stability of the conductive slip ring installation and preventing the conductive slip ring from falling off due to loose fixing screws, which could cause equipment failure and ensure the safe and stable operation of the equipment.

[0015] 2. Rotate the bolt to disconnect the bolt from the threaded hole. At this time, the limit bracket can be moved upward to disengage from the moving slot. The spring is exposed. The spring can then be disassembled using tools, and a new spring can be installed using tools. By designing a replaceable spring structure, the limit mechanism does not need to be replaced as a whole due to spring failure. Only the damaged spring needs to be replaced, which significantly reduces the maintenance cost of the equipment. Attached Figure Description

[0023] This application provides a multi-loop conductive slip ring, which effectively solves the technical problem that the fixing screws are prone to loosening and rotation under the action of these external forces due to the complex working conditions such as continuous vibration, centrifugal force and temperature changes generated during the operation of rotating equipment. When the fixing screws become loose, it will affect the normal operation of the equipment. Long-term loosening may also cause the conductive slip ring to fall off the rotating equipment, causing equipment failure.

[0024] Example

[0025] As shown in Figures 1, 2, 3, 4, and 5, the technical solution in this application effectively solves the problem that due to the complex operating conditions such as continuous vibration, centrifugal force, and temperature changes generated during the operation of rotating equipment, the fixing screws are prone to loosening and rotation under these external forces. When the fixing screws loosen, it will affect the normal operation of the equipment, and long-term loosening may also cause the conductive slip ring to fall off the rotating equipment, leading to equipment failure. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a multi-loop conductive slip ring, including a conductive slip ring body 1. Four fixing screws 2 are threadedly connected to the external side of the conductive slip ring body 1. A limiting mechanism is provided on one side of the conductive slip ring body 1 corresponding to each fixing screw 2 to restrict the movement of the fixing screw 2. Each limiting mechanism includes a moving groove 3, a spring 4, a limiting bracket 5, and a limiting groove 6. The moving groove 3 is located on the outside of the conductive slip ring body 1, and the spring 4 is fixedly connected inside the moving groove 3. The limiting bracket 5 is located at one end... The part is fixedly connected to the outside of the spring 4. The limiting groove 6 is opened on the outside of the limiting frame 5. The head of the fixing screw 2 is located inside the limiting groove 6. Each limiting frame 5 is provided with a spring piece 7 for limiting the movement of the limiting frame 5. Each limiting frame 5 has a deformation groove 8 on one side corresponding to the spring piece 7. One end of the spring piece 7 is fixedly connected to the inside of the deformation groove 8, and the other end extends outward. Each limiting frame 5 has a limiting block 9 fixedly installed on the upper surface to limit the position of the limiting frame 5. Each limiting block 9 has an opening 10 on its outside.

[0027] Each movable groove 3 has a fixed shaft 11 fixedly installed inside, and a spring 4 is movably sleeved on the outside of the fixed shaft 11. Each limiting frame 5 has a movable hole 12 on its outside, which communicates with the inside of the limiting groove 6. The limiting frame 5 is slidably connected to the outside of the fixed shaft 11 through the movable hole 12.

[0028] Each fixed shaft 11 has a bolt 13 at its upper end for limiting the movement of the limit frame 5. Each fixed shaft 11 has a threaded hole 14 on the side corresponding to the bolt 13. The bolt 13 is threaded into the inside of the threaded hole 14. Each limit groove 6 has a receiving hole 15 inside. The receiving hole 15 communicates with the inside of the moving hole 12. The head of the bolt 13 is located inside the receiving hole 15.

[0029] Moving groove 3: Provides a vertical moving track for the limiting frame 5, limiting its direction of movement;

[0030] Spring 4: Sleeves onto the outside of the fixed shaft 11, it stores and releases elastic potential energy through compression and extension, driving the limit frame 5 to automatically reset;

[0031] Limiting bracket 5: It slides along the fixed shaft 11 through the moving hole 12, which drives the limiting groove 6 to lock the head of the fixing screw 2. The mechanical limiting structure directly restricts the rotation of the fixing screw 2.

[0032] Spring 7: It locks the position of the limiting frame 5 by generating friction through deformation. When the limiting frame 5 is pressed down, the spring 7 deforms and fits against the inner wall of the moving groove 3 to prevent the limiting frame 5 from rebounding. After the limiting frame 5 moves up, the spring 7 disengages from the inner wall of the moving groove 3, releases the constraint, and realizes quick unlocking.

[0033] Deformation groove 8: provides a fixed fulcrum and deformation space for the spring piece 7, and guides the spring piece 7 to bend in a preset direction;

[0034] Limiting block 9: Fixed to the upper surface of the limiting frame 5, it abuts against the conductive slip ring body 1 when it touches the bottom, limiting the excessive downward movement of the limiting frame 5;

[0035] Opening 10: Allows tools such as screwdrivers to be inserted, applying external force to move the upper limit bracket 5, overcoming the resistance of the spring piece 7;

[0036] Fixed shaft 11: Serves as a support shaft for spring 4 and limit bracket 5, providing movement guidance;

[0037] Bolt 13 and threaded hole 14: Bolt 13 is screwed into threaded hole 14 of fixed shaft 11, and the head is inserted into receiving hole 15 to limit the upward movement of limit bracket 5 to the extreme position. At the same time, the detachable design facilitates later maintenance.

[0038] Receiving hole 15: connects the moving hole 12 and the limiting groove 6, providing a receiving space for the head of bolt 13.

[0039] Working principle:

[0040] First, when installing the fixing screw 2, press down on the limiting bracket 5 to make it enter the interior of the moving groove 3. During this process, the spring 4 is compressed, and the spring piece 7 deforms and fits tightly against the interior of the moving groove 3. Its outer end rubs against the inner wall of the moving groove 3 to generate resistance, forming a temporary lock, keeping the limiting bracket 5 in a downward state. At this time, the limiting bracket 5 is blocked and cannot move upward. At this time, the limiting block 9 fits against the outside of the conductive slip ring body 1, preventing the limiting bracket 5 from moving downward. The mechanical hard limit prevents the limiting bracket 5 from moving downward too much, protecting the internal spring 4. At this time, the fixing screw 2 can be rotated to fix the conductive slip ring body 1.

[0041] The second step is to screw the fixing screw 2 to the appropriate position. Then, use a tool to insert into the opening 10 to move the limiting bracket 5 upward until the spring piece 7 is outside the moving groove 3. At the same time, the spring 4 releases its elastic potential energy, which helps the limiting bracket 5 move upward along the fixing shaft 11. At this time, the head of the fixing screw 2 is inside the limiting groove 6, and the fixing screw 2 is restricted and cannot rotate.

[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
