Description

Technical Field

[0001] The utility model relates to the technical field of self - rebounding shaft connectors, and specifically relates to a self - rebounding shaft connector. Background Technique

[0002] The self - rebounding shaft connector is a mechanical connection device, usually used in structures that need to rotate or swing. The characteristic of this connector is that it can automatically rebound to the original position after being subjected to external force or torsional force. It usually realizes this self - rebounding characteristic through a torsion spring. Its advantages are that it can improve the flexibility and response speed of the equipment, and at the same time reduce the demand for external force, thus realizing more efficient operation.

[0003] In the existing related technologies, the following defects often exist: when using the self - rebounding shaft connector, since the second connector body rebounds to the original position by hitting the surface of the stop block with the force of the torsion spring rebounding, an impact force will be generated at the moment of impact. This force will be transmitted to the second connector body and the stop block. Over time, it is easy to cause damage to the self - rebounding shaft connector, affecting the performance and service life of the connector.

[0004] Therefore, the utility model provides a self - rebounding shaft connector. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the impact force generated by impact in the existing technology is easy to cause damage to the self - rebounding shaft connector, and a self - rebounding shaft connector is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a self - rebounding shaft connector, including a first connector body, torsion springs are installed on both sides of the first connector body, stop blocks are fixedly connected to both sides of the first connector body, a second connector body is installed on the surface of the first connector body, and a protection structure is arranged on the surface of the first connector body. The protection structure includes two rectangular tubes, both of the rectangular tubes are fixedly connected to the surface of the first connector body, a pin is slidably inserted into the surface of the rectangular tube, a support arm is slidably inserted into the inner wall of the rectangular tube, two limit holes are opened on the surface of the support arm, the size of the pin is adapted to the size of the limit hole, one end of the support arm is fixedly connected with a fixing plate, and a plurality of support plates are fixedly connected to the side of the fixing plate close to the stop block, and a rubber sleeve is sleeved on the surface of the plurality of support plates.

[0007] The effects achieved by the above components are as follows: By setting up a protective structure, it is convenient to install a protective sleeve on the surface of the stop block, thus avoiding the direct impact of the second connector body on the surface of the stop block, preventing damage to the self-returning rotary shaft connector, and further ensuring the performance and service life of the self-returning rotary shaft connector.

[0008] Preferably, guide grooves are provided on both sides of the support arm, and guide arms are slidably connected to the inner walls of the guide grooves. The guide arms are fixedly connected to the surface of the rectangular tube.

[0009] The effects achieved by the above components are as follows: When the support arm moves, the guide arm will slide in the guide groove, and the guide arm restricts the position of the support arm, thus preventing the support arm from disengaging from the rectangular tube.

[0010] Preferably, a spring is sleeved on the surface of the pin, and the two ends of the spring are fixedly connected to the pin and the rectangular tube respectively.

[0011] The effects achieved by the above components are as follows: The pin will insert into the limit hole by virtue of the force of the spring contraction. The spring improves the stability of the pin inserted into the limit hole, thus preventing the pin from coming out of the limit hole due to shaking.

[0012] Preferably, a round rod is connected to the surface of the support arm, and a pull ring is fixedly connected to the end of the round rod away from the support arm.

[0013] The effects achieved by the above components are as follows: The movement of the pull ring will drive the movement of the round rod, and the movement of the round rod will drive the movement of the support arm. The pull ring is convenient for pulling the position of the round rod, and thus is convenient for pulling the support arm.

[0014] Preferably, a plurality of round holes are provided on the surface of the rubber sleeve.

[0015] The effects achieved by the above components are as follows: When the rubber sleeve is impacted, it will deform. At this time, the round holes will be gradually compressed. The round holes can help the rubber sleeve better absorb and disperse the impact force when being impacted or pressed, thus enhancing its shock absorption effect.

[0016] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the support plate.

[0017] The effects achieved by the above components are as follows: The rubber sleeve fits back on the surface of the anti-slip strips on the support plate. The anti-slip strips increase the friction between the rubber sleeve and the support plate, thus improving the stability of the rubber sleeve sleeved on the support plate.

[0018] In summary:

[0019] 1. In the present utility model, by providing a protection structure, a rubber sleeve is sleeved on the surface of the support plate. Then, the support plate is pulled towards the direction close to the stop block. The fixing plate will drive the support plate to move by virtue of the force of the movement of the support arm. The movement of the support plate will drive the rubber sleeve to move. When the support plate moves to an appropriate position, it will drive the rubber sleeve to cover the surface of the stop block, so that the rubber sleeve is sleeved on the surface of the stop block, thereby preventing the second connecting member body from directly hitting the surface of the stop block, resulting in damage to the self-returning rotary shaft connecting member, and further ensuring the performance and service life of the self-returning rotary shaft connecting member.

[0026] Referring to Figure 1 as shown, the present utility model provides a technical solution: a self-returning rotary shaft connecting member, including a first connecting member body 1, torsion springs 2 are installed on both sides of the first connecting member body 1, stop blocks 3 are fixedly connected to both sides of the first connecting member body 1, a second connecting member body 4 is installed on the surface of the first connecting member body 1, and a protection structure 5 is provided on the surface of the first connecting member body 1. By providing the protection structure 5, it is convenient to install a protective sleeve on the surface of the stop block 3, thereby preventing the second connecting member body 4 from directly hitting the surface of the stop block 3, resulting in damage to the self-returning rotary shaft connecting member, and further ensuring the performance and service life of the self-returning rotary shaft connecting member.

[0027] Next, specifically describe the specific setting and function of its protection structure 5.

[0028] Referring to Figure 2 - Figure 5 As shown in the figure, in this embodiment: The protection structure 5 includes two rectangular tubes 501. Both of the two rectangular tubes 501 are fixedly connected to the surface of the first connector body 1. A pin 502 is slidably inserted into the surface of the rectangular tube 501, and a support arm 503 is slidably inserted into the inner wall of the rectangular tube 501. Two limit holes 504 are formed on the surface of the support arm 503. The size of the pin 502 is adapted to the size of the limit holes 504. One end of the support arm 503 is fixedly connected to a fixing plate 505. A plurality of support plates 506 are fixedly connected to the side of the fixing plate 505 close to the stopper 3. A rubber sleeve 507 is sleeved on the surface of the plurality of support plates 506. Guide grooves 508 are formed on both sides of the support arm 503. A guide arm 509 is slidably connected to the inner wall of the guide groove 508. The guide arm 509 is fixedly connected to the surface of the rectangular tube 501. When the support arm 503 moves, the guide arm 509 will slide in the guide groove 508. The guide arm 509 serves to limit the position of the support arm 503, thereby preventing the support arm 503 from disengaging from the rectangular tube 501. A spring 510 is sleeved on the surface of the pin 502. Both ends of the spring 510 are fixedly connected to the pin 502 and the rectangular tube 501 respectively. The pin 502 will be inserted into the limit hole 504 by the force of the contraction of the spring 510. The spring 510 serves to improve the stability of the pin 502 inserted into the limit hole 504, thereby preventing the pin 502 from shaking out of the limit hole 504. A round rod 511 is connected to the surface of the support arm 503. A pull ring 512 is fixedly connected to the end of the round rod 511 away from the support arm 503. Moving the pull ring 512 will drive the round rod 511 to move, and moving the round rod 511 will drive the support arm 503 to move. The pull ring 512 serves to facilitate pulling the round rod 511, and thus facilitate pulling the support arm 503. A plurality of round holes 513 are formed on the surface of the rubber sleeve 507. When the rubber sleeve 507 is subjected to an impact force, it will deform. At this time, the round holes 513 will be gradually compressed. The round holes 513 can help the rubber sleeve 507 better absorb and disperse the impact force when being impacted or pressed, thereby enhancing its shock absorption effect. A plurality of anti-slip strips 514 are fixedly connected to the surface of the support plate 506. The rubber sleeve 507 will fit back on the surface of the anti-slip strips 514 on the support plate 506. The anti-slip strips 514 serve to increase the friction between the rubber sleeve 507 and the support plate 506, thereby improving the stability of the rubber sleeve 507 sleeved on the support plate 506.

[0029] Working principle: When it is necessary to install the rubber sleeve 507 on the surface of the stop block 3, first pull the bolt 502. The bolt 502 will slide within the rectangular tube 501 and gradually disengage from the limit hole 504. When the bolt 502 moves, it will stretch the spring 510. After the bolt 502 disengages from the limit hole 504, pull the pull ring 512. The movement of the pull ring 512 will drive the round rod 511 to move. The movement of the round rod 511 will drive the support arm 503 to move. The support arm 503 will slide within the rectangular tube 501 when it moves. When the support arm 503 moves, it will cause the guide arm 509 to slide within the guide groove 508. The guide arm 509 reaches the position to limit the support arm 503, thereby preventing the support arm 503 from disengaging from the rectangular tube 501. When the support arm 503 moves, it will drive the fixing plate 505 to move. The movement of the fixing plate 505 will drive the support plate 506 to move away from the stop block 3. When the support plate 506 moves to an appropriate position, put the rubber sleeve 507 on the surface of the support plate 506. The rubber sleeve 507 will fit back on the surface of the anti-slip strip 514 on the support plate 506. The anti-slip strip 514 increases the friction between the rubber sleeve 507 and the support plate 506, thereby improving the stability of the rubber sleeve 507 on the support plate 506. Then pull the pull ring 512 in the direction close to the stop block 3. The movement of the pull ring 512 will drive the round rod 511 to move. The support plate 506 will slide within the rectangular tube 501 by the force of the movement of the round rod 511. The fixing plate 505 will drive the support plate 506 to move by the force of the movement of the support arm 503. The movement of the support plate 506 will drive the rubber sleeve 507 to move. When the support plate 506 moves to an appropriate position, it will drive the rubber sleeve 507 to cover the surface of the stop block 3, so that the rubber sleeve 507 is sleeved on the surface of the stop block 3. Then release the bolt 502. The bolt 502 will insert into the limit hole 504 by the force of the contraction of the spring 510. The bolt 502 reaches the position to limit the support arm 503, thereby restricting the position of the rubber sleeve 507. The spring 510 improves the stability of the bolt 502 inserted into the limit hole 504, thereby preventing the bolt 502 from shaking out of the limit hole 504. At this time, when the second connecting piece body 4 rebounds, it will hit the surface of the rubber sleeve 507. The rubber sleeve 507 will deform under the impact force. At this time, the round hole 513 will be gradually compressed. The round hole 513 can help the rubber sleeve 507 better absorb and disperse the impact force when it is hit or pressed, thereby enhancing its shock absorption effect.
