Description

Technical Field

[0001] This utility model specifically relates to a quick-release coupling. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

[0003] Traditional couplings often require slight movement of the equipment when aligning them after installation. This is very difficult for interference fit couplings and usually requires disassembly and reassembly. Utility Model Content

[0004] Purpose of the utility model: To provide a quick-release coupling that solves the above-mentioned problems existing in the prior art.

[0005] Technical Solution: A quick-release coupling includes a left bushing and a right bushing. One end of the left bushing and one end of the right bushing are fitted onto a rotating shaft. A slot is formed at the other end of each bushing. Several mounting slots are circumferentially arranged along the edges of each bushing. A slider is installed between the left and right bushings. Several limiting slots are formed on both sides of the slider. The limiting slots are arranged circumferentially and correspond one-to-one with the mounting slots. A connecting component is installed in each mounting slot. The connecting component is inserted into the limiting slot to connect and limit the slider to the left or right bushing.

[0006] Preferably, the limiting groove includes an annular groove that extends inward along the end face of the slider. A cylindrical hole is provided in the slider and communicates with the annular groove. The diameter of the cylindrical hole is larger than the diameter of the annular groove. The annular groove and the cylindrical hole form a receiving space with a convex longitudinal cross-section. A hexagonal groove is provided at the bottom of the cylindrical hole and communicates with the cylindrical hole.

[0007] Preferably, the connecting assembly includes a limiting part for limiting connection with the slider. A connecting part is installed at the end of the limiting part near the left or right bushing. The connecting part is inserted into the mounting groove. A lead screw is rotatably installed in the connecting part. The end of the lead screw is rotatably connected to the end of the limiting part. The middle section of the lead screw is engaged with the limiting part. The lead screw is used to adjust the outer diameter of the limiting part.

[0008] Preferably, the connecting part includes a limiting ring, which abuts against the left or right bushing. A guide post is installed at one end of the limiting ring, and the axis of the guide post coincides with the axis of the limiting ring. The guide post is inserted into the mounting groove, and an insertion hole is provided in the center of the limiting ring, through which the guide post passes.

[0009] Preferably, the limiting part includes a mounting base column, the end of the lead screw is rotatably connected to the mounting base column, a plurality of small scissor bars are mounted on the side of the mounting base column, one inner end of each small scissor bar is rotatably connected to the outer wall of the mounting base column, a movable ring is provided above the mounting base column, the movable ring is engaged with the lead screw, the other inner end of each small scissor bar is rotatably connected to the outer wall of the movable ring, and the two outer ends of each small scissor bar are respectively rotatably connected to the two ends of a limiting plate. The limiting plate moves away from or closer to the mounting base column under the cooperation of the movable ring, the lead screw and the small scissor bars.

[0010] Preferably, the limiting part further includes a hexagonal protrusion, which is installed on the end of the mounting base away from the moving ring, and the hexagonal protrusion is inserted into a portion of the limiting groove.

[0011] Beneficial effects: This utility model relates to a quick-release coupling. When the coupling needs to be installed or disassembled, only an external force needs to be applied to the lead screw in the connecting assembly to rotate it. This will drive the limiting plate in the limiting part to move away from or towards the mounting base column, thereby realizing the installation or separation of the left or right bushing and the slider. No professional coupling disassembly tools are required to complete the disassembly and installation of the coupling. Furthermore, by connecting the left or right bushing and the slider through the connecting assembly, it is possible to ensure that the bushing and the slider maintain coaxiality when connected, reducing installation errors.

[0014] like Figures 1 to 6 As shown, this utility model provides a technical solution: a quick-release coupling, including a left shaft sleeve 1 and a right shaft sleeve 2, wherein one end of the left shaft sleeve 1 is fitted onto a rotating shaft, and one end of the right shaft sleeve 2 is fitted onto a rotating shaft, as shown. Figure 3 As shown, a slot 3 is respectively formed at the other end of the left bushing 1 and the right bushing 2. Several mounting slots 4 are circumferentially arranged along the edges of the left bushing 1 and the right bushing 2. A slider 5 is installed between the left bushing 1 and the right bushing 2. Several limiting slots 6 are formed on both sides of the slider 5. The limiting slots 6 are arranged circumferentially, and each limiting slot 6 corresponds one-to-one with a mounting slot 4. Each limiting slot 6 includes an annular groove 61, which extends inward along the end face of the slider 5. A cylindrical hole 62 is provided inside the slider 5, which communicates with the annular groove 61. The diameter of the cylindrical hole 62 is larger than the diameter of the annular groove 61. The annular groove 61 and the cylindrical hole 62 form a receiving space with a convex longitudinal cross-section. A hexagonal groove 63 is provided at the bottom of the cylindrical hole 62, which communicates with the cylindrical hole 62. Each mounting groove 4 is equipped with a connecting component, which includes a limiting part 7, a connecting part, and a lead screw 9. The limiting part 7 is inserted into the limiting part 9. Within the positioning groove 6, the slider 5 is connected and limited to the left bushing 1 or the right bushing 2. A connecting part 8 is installed near the end of the limiting part 7 close to the left bushing 1 or the right bushing 2. The connecting part 8 is inserted into the mounting groove 4. A lead screw 9 is rotatably installed within the connecting part 8. The end of the lead screw 9 is rotatably connected to the end of the limiting part 7, and the middle section of the lead screw 9 is engaged with the limiting part 7. The lead screw 9 is used to adjust the outer diameter of the limiting part 7, causing the limiting part 7 to abut against or disengage from the limiting groove 6. When the coupling needs to be installed or disassembled, the slot 6 only needs to apply external force to the lead screw 9 in the connecting assembly to rotate it. This will drive the limiting plate 74 in the limiting part 7 to move away from or closer to the mounting base 71, thereby enabling the installation or separation of the left bushing 1 or right bushing 2 from the slider 5. No special coupling disassembly tools are required to complete the disassembly and installation of the coupling. Furthermore, by connecting the left bushing 1 or right bushing 2 with the slider 5 through the connecting assembly, it is possible to ensure that the bushing and slider 5 maintain coaxiality when connected, reducing installation errors.

[0015] In a further embodiment, the connecting part 8 includes a limiting ring 81, which abuts against the left bushing 1 or the right bushing 2. A guide post 82 is installed at one end of the limiting ring 81, and the axis of the guide post 82 coincides with the axis of the limiting ring 81. The end of the guide post 82 is connected to the limiting part 7, and the guide post 82 is inserted into the mounting groove 4. An insertion hole 83 is provided in the center of the limiting ring 81, and the insertion hole 83 passes through the guide post. Thus, when the limiting part 7 and the slider 5 abut against each other, the bushing and the slider 5 are connected and limited by the cooperation of the guide post 82.

[0016] In a further embodiment, the limiting part 7 includes a mounting base post 71. A hexagonal protrusion 75 is mounted on the end of the mounting base post 71 away from the moving ring 73. The hexagonal protrusion 75 is inserted into a hexagonal groove 63, and the travel is radially limited by the cooperation between the hexagonal protrusion 75 and the hexagonal groove 63. The end of the lead screw 9 is rotatably connected to the mounting base post 71. A plurality of small scissor bars 72 are mounted on the side of the mounting base post 71. One inner end of each small scissor bar 72 is rotatably connected to the outer wall of the mounting base post 71. A moving ring 73 is provided above the mounting base post 71. The moving ring 73 is engaged with the lead screw 9. The inner end of the small scissor bar 72 is rotatably connected to the outer wall of the moving ring 73. The outer ends of the small scissor bar 72 are rotatably connected to the two ends of the limiting plate 74. With the cooperation of the moving ring 73, the lead screw 9 and the small scissor bar 72, the limiting plate 74 moves away from or close to the mounting base post 71. When the limiting plate 74 is close to the mounting base post 71, the limiting part 7 is located in the center of the limiting groove 6. At this time, the limiting part 7 can smoothly disengage from the limiting groove 6. When the limiting plate 74 is away from the mounting base post 71, the limiting plate 74 contacts the inner wall surface of the limiting groove 6. At this time, the limiting part 7 abuts against the limiting groove 6, so that the slider 5 and the bushing form a connection limit.
