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, the sliding sleeve is often fixed in relative position to the device body through a pin structure. This requires the device body to have multiple holes that mate with the pin structure. When the pin structure on the sliding sleeve mates with different holes, the sliding sleeve and the device body achieve different relative positional relationships. However, since the positions of the holes on the device body are fixed, the sliding sleeve and the device body can only have a few relative positional relationships, which cannot achieve stepless adjustment of the sliding sleeve. Sometimes this can prevent users from fixing the sliding sleeve in the most comfortable position for them. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sliding sleeve that can achieve stepless adjustment of position on the device body.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sliding sleeve, comprising: The main body is provided with a limiting cavity, which is slidably engaged with the equipment body, and an avoidance groove is provided on the cavity wall of the limiting cavity; A locking element, which is slidably disposed in the clearance groove; An operating lever is rotatably connected to the main body. When the operating lever is rotated, it pushes the locking member to slide along the clearance groove to abut against the device body.

[0006] Furthermore, the operating lever includes a cam end that abuts against the locking member and extends into the clearance groove.

[0007] Furthermore, the cam end has a locking surface and an unlocking surface that is angled to the locking surface. The locking surface and the unlocking surface are connected by a transition surface. The distance from the locking surface to the rotation center axis of the operating lever is greater than the distance from the unlocking surface to the rotation center axis of the operating lever.

[0008] Furthermore, the locking element is an elastic structural element.

[0009] Furthermore, the diameter of the clearance groove is adapted to the locking element.

[0010] Furthermore, the area of ​​the cavity wall of the limiting cavity opposite to the locking member is provided with an elastic abutment.

[0011] Furthermore, the inner surface of the cavity wall of the limiting cavity is provided with a mounting groove, and a portion of the elastic abutment is installed in the mounting groove.

[0012] Furthermore, the operating lever is L-shaped overall.

[0013] Furthermore, the number of operating levers is multiple, spaced apart, and the rotation center axes of the multiple operating levers are coaxially arranged.

[0014] Furthermore, two adjacent operating levers are connected by a connecting arm.

[0015] Furthermore, the main body is provided with a mounting structure for installing accessories.

[0016] The beneficial effects of this invention are as follows: After the sliding sleeve is slid to a preset position on the device body, the user can rotate the operating lever to make the locking member tightly press against the device body, thereby fixing the relative position of the sliding sleeve on the device body. During the sliding stroke, the locking member can press against any position on the device body, so the sliding sleeve can achieve stepless position adjustment on the device body, thus meeting the most comfortable usage needs of different users and enhancing the user experience. Furthermore, there is no need to set holes on the device body, which helps to improve the structural strength of the device body and simplifies the processing technology of the device body.

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please combine Figures 1 to 3 The sliding sleeve includes a main body 1, a locking member 3, and an operating lever 2. The main body 1 is provided with a limiting cavity 11, which is slidably engaged with the device body 5. An avoidance groove 13 is provided on the cavity wall of the limiting cavity 11. The locking member 3 is slidably disposed in the avoidance groove 13. The operating lever 2 is rotatably connected to the main body 1. When the operating lever 2 rotates, it pushes the locking member 3 to slide along the avoidance groove 13 to abut against the device body 5.

[0022] As can be seen from the above description, the beneficial effects of this utility model are as follows: After the sliding sleeve is slid to a preset position on the device body 5, the user can rotate the operating lever 2 to make the locking member 3 tightly press against the device body 5, thereby fixing the relative position of the sliding sleeve on the device body 5. During the sliding stroke, the locking member 3 can press against any position on the device body 5, so the sliding sleeve can achieve stepless position adjustment on the device body 5, thereby meeting the most comfortable use needs of different users and enhancing the user experience. Moreover, there is no need to set holes on the device body 5, which is conducive to improving the structural strength of the device body 5 and simplifying the processing technology of the device body 5.

[0023] like Figure 2 and Figure 3 As shown, the operating lever 2 further includes a cam end 21, which abuts against the locking member 3 and extends into the clearance groove 13.

[0024] As can be seen from the above description, the cam structure is a common structure for creating a lever effect. It is easy to process and helps control the manufacturing cost of the operating lever 2.

[0025] like Figures 3 to 5As shown, the cam end 21 further has a locking surface 211 and an unlocking surface 212 that is angled to the locking surface 211. The locking surface 211 and the unlocking surface 212 are connected by a transition surface 213. The distance from the locking surface 211 to the rotation center axis of the operating lever 2 is greater than the distance from the unlocking surface 212 to the rotation center axis of the operating lever 2.

[0026] As described above, during the rotation of the cam end 21, the locking surface 211 can drive the locking member 3 to move towards the device body 5 and press against the device body 5. When the unlocking surface 212 approaches the locking member 3, the locking member 3 has the activity margin to slide away from the device body 5. At this time, the locking member 3 no longer presses against the device body 5, and the sliding sleeve can slide along the device body 5.

[0027] Furthermore, the locking element 3 is an elastic structural element.

[0028] As can be seen from the above description, the elastic structural component itself can deform. When the locking component 3 is pressed against the equipment body 5, the locking component 3 and the equipment body 5 can form a larger contact area, thereby forming a larger static friction force, thus preventing the sliding sleeve from sliding unexpectedly relative to the equipment body 5.

[0029] like Figure 3 and Figure 4 As shown, the diameter of the clearance groove 13 is adapted to the locking member 3.

[0030] As can be seen from the above description, the locking member 3 has limited freedom of movement in the relief groove 13, ensuring that the operating lever 2 can effectively abut against the locking member 3, thereby allowing the locking member 3 to press against the device body 5.

[0031] like Figure 3 and Figure 5 As shown, further, the area of ​​the cavity wall of the limiting cavity 11 opposite to the locking member 3 is provided with an elastic abutment 4.

[0032] As can be seen from the above description, the elastic abutment 4 opposite to the locking member 3 cooperates with the locking member 3 to clamp and fix the device body 5 in a relative direction, which helps to further reduce the risk of the sliding sleeve sliding unexpectedly relative to the device body 5.

[0033] like Figure 3 and Figure 5 As shown, further, the inner surface of the cavity wall of the limiting cavity 11 is provided with a mounting groove 14, and a portion of the elastic contact member 4 is installed in the mounting groove 14.

[0034] As can be seen from the above description, the presence of the mounting groove 14 enables the elastic abutment 4 to be stably installed and fixed, improving the phenomenon that the elastic abutment 4 becomes loose due to sliding friction with the equipment body 5 during the sliding process of the sliding sleeve.

[0035] like Figures 2 to 5 As shown, the operating lever 2 is L-shaped overall.

[0036] As described above, the L-shaped operating lever 2 has a longer power arm, allowing users to unlock / lock the sliding sleeve and the device body 5 with relatively little force, which enhances the user experience.

[0037] like Figure 4 and Figure 6 As shown, furthermore, the number of operating levers 2 is a plurality of them arranged at intervals, and the rotation center axis of the plurality of operating levers 2 is coaxially arranged.

[0038] As can be seen from the above description, setting multiple operating levers 2 helps to increase the locking force between the sliding sleeve and the equipment body 5, and further reduces the risk of the sliding sleeve sliding unexpectedly.

[0039] Furthermore, two adjacent operating levers 2 are connected by a connecting arm 24.

[0040] As can be seen from the above description, the existence of the connecting arm 24 not only facilitates the processing and manufacturing of multiple operating levers 2, but also provides a handle for the user to hold, so that the user can operate multiple operating levers 2 at the same time.

[0041] like Figure 1 As shown, the main body 1 is further provided with a mounting structure 12 for mounting the accessory 6.

[0042] As described above, the relative position of accessory 6 and device body 5 can be adjusted by using the sliding sleeve, so that users can use accessory 6 more conveniently.

[0043] Embodiment 1 of this utility model is as follows: Figure 1 As shown, the sliding sleeve can be applied to fitness equipment, which includes a body 5. In the fitness equipment product, the body 5 is a rod-shaped structural component.

[0044] Please combine Figures 1 to 5The sliding sleeve includes a main body 1, a locking member 3, and an operating lever 2. The main body 1 has a limiting cavity 11, which is slidably engaged with the device body 5, meaning the sliding sleeve can slide along the device body 5. An avoidance groove 13 is formed on the cavity wall of the limiting cavity 11, and the locking member 3 is slidably disposed in the avoidance groove 13. The locking member 3 is used to lock the relative position between the sliding sleeve and the device body 5. The operating lever 2 is rotatably connected to the main body 1. The user locks and unlocks the sliding sleeve by rotating the operating lever 2. Specifically, when the operating lever 2 rotates in one direction, it pushes the locking member 3 to slide along the avoidance groove 13 to press against the device body 5. When the operating lever 2 rotates in the opposite direction, the pressing force of the locking member 3 against the device body 5 weakens or even disappears, thereby allowing the sliding sleeve to slide along the device body 5.

[0045] The clearance groove 13 is preferably a through hole structure. The locking member 3 is located inside the through hole structure. The locking member 3 is limited by the inner peripheral wall of the through hole structure. One end of the locking member 3 is stopped by the equipment body 5, and the other end of the locking member 3 is stopped by the end of the operating lever 2. Therefore, the locking member 3 cannot disengage from the clearance groove 13.

[0046] like Figure 1 As shown, the main body 1 is provided with a mounting structure 12 for mounting accessories 6. Accessories 6 include, but are not limited to, structural components such as pulley blocks and support arms. Furthermore, accessories 6 can be either non-detachably connected to the main body 1 or detachably connected, depending on actual needs.

[0047] like Figures 2 to 3 As shown, in some embodiments, the main body 1 is in the shape of a complete ring frame, while in order to save production materials and reduce the manufacturing cost of the main body 1, in this embodiment, the main body 1 is in the shape of an open ring.

[0048] like Figures 2 to 4 As shown, in some embodiments, the inner wall of the limiting cavity 11 is provided with a damping element 7, and the inner surface of the damping element 7 has multiple raised ribs 71, which contact the device body 5. The presence of the damping element 7 can prevent the main body 1 from falling unexpectedly and rapidly due to its own weight.

[0049] Please combine Figure 3 , Figures 5 to 7 The operating lever 2 includes a cam end 21, which abuts against the locking member 3 and extends into the clearance groove 13. In this embodiment, the cam end 21 has a locking surface 211 and an unlocking surface 212 that is angled to the locking surface 211. The locking surface 211 and the unlocking surface 212 are connected by a transition surface 213, such as... Figure 6As shown, the distance A from the locking surface 211 to the rotation center axis of the operating lever 2 is greater than the distance B from the unlocking surface 212 to the rotation center axis of the operating lever 2. Optionally, the locking surface 211 is perpendicular to the unlocking surface 212; the transition surface 213 is an arc surface.

[0050] In one or more embodiments, the locking member 3 is an elastic structural member, such as a structural member made of rubber, a structural member made of engineering plastic, etc.

[0051] like Figures 2 to 5 As shown, to ensure the effectiveness of user operation, it is preferable that the diameter of the clearance groove 13 is adapted to the locking member 3.

[0052] Optionally, the cavity wall of the limiting cavity 11 is provided with an elastic abutment 4 in the area opposite to the locking member 3. The elastic abutment 4 is used to press against the side of the device body 5 away from the locking member 3, so as to achieve the effect of clamping the device body 5 in cooperation with the locking member 3. The material of the elastic abutment 4 may be the same as or different from the material of the locking member 3.

[0053] like Figure 3 and Figure 5 As shown, further, the inner surface of the cavity wall of the limiting cavity 11 is provided with an installation groove 14, and a portion of the elastic abutment 4 is installed in the installation groove 14. In one or more embodiments, the elastic abutment 4 is glued to the cavity wall of the limiting cavity 11. At this time, the installation groove 14 can hold more adhesive, thereby increasing the bonding area of ​​the elastic abutment 4 and ensuring the stability of the connection between the two.

[0054] In some embodiments, the operating lever 2 is in the shape of a straight line or other shapes. In this embodiment, for example... Figure 6 As shown, the operating lever 2 is generally L-shaped; specifically, the operating lever 2 includes a first rod portion 22 and a second rod portion 23 connected together. The length of the first rod portion 22 is shorter than that of the second rod portion 23. The end of the first rod portion 22 away from the second rod portion 23 is a cam end 21. The rotation center axis of the operating lever 2 is located on the cam end 21. More specifically, the cam end 21 is rotatably connected to the main body 1 through a bearing.

[0055] Please combine Figure 1 , Figure 4 and Figure 6To ensure a more stable lock between the sliding sleeve and the device body 5, it is preferable to have multiple operating levers 2 spaced apart, with their rotation center axes coaxial. For ease of user operation, adjacent operating levers 2 are connected by a connecting arm 24. In this embodiment, there are two operating levers 2, and the connecting arm 24 connecting the second rod portion 23 of the two operating levers 2 can be used as a handle, facilitating the user's rotation of the operating lever 2. Simultaneously, when the user slides the sliding sleeve, they can hold the connecting arm 24 to operate the sliding sleeve. In other embodiments, it is also feasible to have only one operating lever 2.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
