Description

Technical Field

[0001] This utility model relates to the technical field of fitness equipment accessories, and in particular to sliding sleeves. Background Technology

[0002] To allow for adjustable positions of components such as pulley blocks and support arms on the equipment body, some fitness equipment will mount these components on a sliding sleeve, which can be slidably installed on the equipment body.

[0003] In existing technologies, sliding sleeves are often fixed in a relative position to the device body through a pin structure. The device body has multiple pin holes spaced apart from top to bottom. When the pin structure on the sliding sleeve engages with different holes, the sliding sleeve and the device body achieve different relative positional relationships. However, not all users prefer the pull-out unlocking method of the pin structure. Some users prefer the press-out unlocking method, but existing technologies lack sliding sleeves that can be unlocked by pressing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sliding sleeve that can be unlocked by pressing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a sliding sleeve, including a main body, a rotating part, a resetting part and a locking rod. The main body is provided with a limiting cavity, which is slidably engaged with the equipment body. The cavity wall of the limiting cavity is provided with a clearance opening. The rotating part is fixed to the locking rod and rotatably connected to the main body. The resetting part connects the main body and the rotating part to drive a part of the locking rod to pass through the clearance opening and extend into the limiting cavity. The locking rod is used to engage with the locking groove on the equipment body.

[0006] Furthermore, the locking rod and the rotating component are separate structures, or the locking rod and the rotating component are integrally formed.

[0007] Furthermore, one end of the rotating member is connected to the locking rod, and the other end of the rotating member has a pressing part. The rotating member is connected to the main body through a rotating shaft, which is located between the locking rod and the pressing part.

[0008] Furthermore, the other end of the rotating component is connected to the reset component; or, the reset component is a torsion spring sleeved on the rotating shaft.

[0009] Furthermore, the main body has a receiving cavity for accommodating the locking rod, the receiving cavity being located on one side of the limiting cavity, and the receiving cavity communicating with the limiting cavity through the clearance opening.

[0010] Furthermore, the cavity wall of the receiving cavity is provided with an observation port, which is provided corresponding to the locking rod.

[0011] Furthermore, the cavity wall of the limiting cavity is provided with a damping pad, and the damping pad is provided with a through hole corresponding to the clearance opening.

[0012] Furthermore, the inner wall of the damping pad is provided with a plurality of raised ribs, which are used to contact the device body.

[0013] Furthermore, the damping pad is made of rubber.

[0014] Furthermore, the main body is provided with a mounting structure for installing accessories.

[0015] The beneficial effects of this utility model are as follows: This sliding sleeve has a simple and novel structure, which can achieve press-to-unlock, and is more in line with the usage habits of some users. When the user needs to change the height of the sliding sleeve, he / she only needs to grasp the main body and press the part of the rotating part exposed on the main body with his / her palm. The rotating part then overcomes the elasticity of the reset part and rotates, driving the locking rod fixed to it to swing synchronously, so that the locking end of the locking rod exits the locking groove on the device body, releasing the limit between the main body and the device body. At this time, the user can continue to grasp the main body with one hand and drive the main body to slide along the device body to the required height. After reaching the target position, the user releases the press, and the reset part immediately drives the rotating part to rotate back. The locking rod passes through the clearance hole again and enters the corresponding locking groove to engage, completing the locking. The whole process can be performed with one hand, and the operation process is very simple. Attached Figure Description

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: The sliding sleeve has a simple and novel structure, which can realize press-to-unlock, and is more in line with the usage habits of some users. When the user needs to change the height of the sliding sleeve, he / she only needs to grasp the main body 2 and press the rotating part 3 exposed on the part of the main body 2. The rotating part 3 then overcomes the elasticity of the reset part 4 and rotates, driving the locking rod 5 fixed to it to swing synchronously, so that the locking end of the locking rod 5 exits the locking groove 11 on the device body 1, releasing the limitation between the main body 2 and the device body 1. At this time, the user can continue to grasp the main body 2 with one hand and drive the main body 2 to slide along the device body 1 to the required height. After reaching the target position, the user releases the press, and the reset part 4 immediately drives the rotating part 3 to rotate back. The locking rod 5 passes through the avoidance opening 211 again and enters the corresponding locking groove 11 to engage, completing the locking. The whole process can be performed with one hand, and the operation process is very simple.

[0021] Please refer to Figure 2 Furthermore, the locking rod 5 and the rotating component 3 are separate structures, or the locking rod 5 and the rotating component 3 are integrally formed.

The rotating member 3 is connected to the main body 2 through a rotating shaft 6, and the rotating shaft 6 is located between the locking rod 5 and the pressing part 31.

[0024] As can be seen from the above description, the presence of the pressing part 31 makes it convenient for the user to press the rotating part 3 to drive the locking rod 5 out of the limiting cavity 21.

[0025] Please refer to Figure 2 Furthermore, the other end of the rotating member 3 is connected to the reset member 4; or, the reset member 4 is a torsion spring sleeved on the rotating shaft 6.

[0026] As can be seen from the above description, the position of the reset component 4 corresponding to the rotating component 3 can be selected according to the specific type of the reset component 4.

[0027] Please refer to Figure 2 Furthermore, the main body 2 has a receiving cavity 22 for receiving the locking rod 5. The receiving cavity 22 is located on one side of the limiting cavity 21, and the receiving cavity 22 is connected to the limiting cavity 21 through the clearance opening 211.

[0028] As described above, the receiving cavity 22 can effectively protect the locking rod 5 and prevent the user from being pinched by the locking rod 5 during operation.

[0029] Please refer to Figures 1 to 2 Furthermore, the cavity wall of the receiving cavity 22 is provided with an observation port 23, which is provided corresponding to the locking rod 5.

[0030] As described above, users can observe through the observation port 23 whether the locking rod 5 has entered the locked state, thereby ensuring that the sliding sleeve has been stably locked on the device body 1.

[0031] Please refer to Figures 2 to 6 Furthermore, a damping pad 8 is provided on the cavity wall of the limiting cavity 21, and the damping pad 8 is provided with a through hole 81 corresponding to the clearance opening 211.
