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 and locking of the sliding sleeve. Sometimes this can prevent users from locking 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 and locking of position on the device body.

[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 locking member, a handle, and a locking member. 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 relief groove, and the locking member is slidably disposed in the relief groove. The handle is rotatably connected to the main body. When the handle is rotated, it pushes the locking member to slide along the relief groove to press against the equipment body. The locking member is movably disposed on the main body, and the handle has a mating part that cooperates with the locking member.

[0006] Furthermore, the handle includes a power arm, one end of which is provided with a cam end, the cam end abutting against the locking member, and the cam end extending 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 handle is greater than the distance from the unlocking surface to the rotation center axis of the handle.

[0008] Furthermore, the handle includes a grip arm and multiple power arms, the grip arm is connected to each of the power arms, the grip arm is disposed away from the cam end, the main body has multiple clearance grooves, each clearance groove is equipped with the locking element, and the clearance grooves are configured one-to-one with the cam end.

[0009] Furthermore, the handle also includes a reinforcing arm, which connects at least two of the power arms, and the mating part is disposed on the reinforcing arm.

[0010] Furthermore, the lock includes a sliding pin, and the mating part is a lock hole.

[0011] Furthermore, the locking component also includes a first elastic element, which connects the sliding pin to the main body.

[0012] Furthermore, the end of the sliding pin is provided with a guide surface.

[0013] Furthermore, the handle is also provided with an unlocking component, which includes a pressing member for pushing the sliding pin out of the lock hole. The handle is provided with a mounting hole communicating with the lock hole, and the pressing member is located at the mounting hole.

[0014] Furthermore, the unlocking component also includes a second elastic element that connects the handle to the pressing element.

[0015] The beneficial effects of this utility model are as follows: After the sliding sleeve is slid to a preset position on the device body, the user can rotate the handle 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, when the locking member in the sliding sleeve presses against the device body, the locking engagement between the locking member and the mating part ensures that the handle will not rotate unexpectedly, causing the sliding sleeve to unlock accidentally and slide unintended, thus improving the safety of the sliding sleeve and further enhancing the user experience. In addition, there is no longer a need to set holes on the device body, which helps to improve the structural strength of the device body and simplifies the manufacturing process.

[0018] 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.

[0019] Please refer to Figures 1 to 4 The sliding sleeve includes a main body 1, a locking member 2, a handle 3, and a locking member 4. The main body 1 is provided with a limiting cavity 11, which is slidably engaged with the equipment body 10. The cavity wall of the limiting cavity 11 is provided with a relief groove 12, and the locking member 2 is slidably disposed in the relief groove 12. The handle 3 is rotatably connected to the main body 1. When the handle 3 is rotated, it pushes the locking member 2 to slide along the relief groove 12 to press against the equipment body 10. The locking member 4 is movably disposed on the main body 1, and the handle 3 has a mating part 31 that mates with the locking member 4.

[0020] 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 10, the user can rotate the handle 3 to make the locking member 2 tightly press against the device body 10, thereby fixing the relative position of the sliding sleeve on the device body 10. During the sliding stroke, the locking member 2 can press against any position on the device body 10, so the sliding sleeve can achieve stepless position adjustment on the device body 10, thereby meeting the most comfortable use needs of different users and enhancing the user experience. Moreover, when the locking member 2 in the sliding sleeve presses against the device body 10, the locking engagement between the locking member 4 and the mating part 31 can ensure that the handle 3 will not rotate unexpectedly, causing the sliding sleeve to unlock accidentally and slide unexpectedly, which is beneficial to improving the safety of the sliding sleeve and further enhancing the user experience. In addition, there is no need to set holes on the device body 10, which is beneficial to improving the structural strength of the device body 10 and simplifying the processing technology of the device body 10.

[0021] Please refer to Figure 3 and Figure 4 Furthermore, the handle 3 includes a power arm 32, one end of which is provided with a cam end 33, the cam end 33 abuts against the locking member 2, and the cam end 33 extends into the clearance groove 12.

[0022] 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 handle 3.

[0023] Please refer to Figure 4 Furthermore, the cam end 33 has a locking surface 331 and an unlocking surface 332 that is angled to the locking surface 331. The locking surface 331 and the unlocking surface 332 are connected by a transition surface 333. The distance from the locking surface 331 to the rotation center axis of the handle 3 is greater than the distance from the unlocking surface 332 to the rotation center axis of the handle 3.

[0024] As described above, during the rotation of the cam end 33, the locking surface 331 can drive the locking member 2 to move towards the device body 10 and press against the device body 10. When the unlocking surface 332 approaches the locking member 2, the locking member 2 has the activity margin to slide away from the device body 10. At this time, the locking member 2 no longer presses against the device body 10, and the sliding sleeve can slide along the device body 10.

[0025] Please refer to Figure 3Furthermore, the handle 3 includes a grip arm 34 and a plurality of power arms 32. The grip arm 34 is connected to each of the power arms 32. The grip arm 34 is disposed away from the cam end 33. The main body 1 has a plurality of clearance grooves 12. Each clearance groove 12 is equipped with a locking member 2. The clearance grooves 12 are configured to correspond one-to-one with the cam end 33.

[0026] As described above, there are multiple locking elements 2, and the sliding sleeve can provide multi-point clamping to the device body 10, which helps to ensure the locking effect of the sliding sleeve on the device body 10. The presence of the grip arm 34 provides a gripping position for the user's hand, so that the user can operate multiple power arms 32 simultaneously.

[0027] Please refer to Figure 3 and Figure 7 Furthermore, the handle 3 also includes a reinforcing arm 35, which connects at least two of the power arms 32, and the mating part 31 is provided on the reinforcing arm 35.

[0028] As can be seen from the above description, the reinforcing arm 35 can improve the overall structural strength of the handle 3, and at the same time, it can provide a mounting position for the mating part 31.

[0029] Please refer to Figure 5 and Figure 6 Furthermore, the locking component 4 includes a sliding pin 41, and the mating part 31 is a lock hole.

[0030] As can be seen from the above description, the pin mechanism has a simple structure and is easy for users to operate.

[0031] Furthermore, the locking element 4 also includes a first elastic element 42, which connects the sliding pin 41 to the main body 1.

[0032] As can be seen from the above description, the first elastic element 42 can act as a stopper for the sliding pin 41, which helps to prevent the sliding pin 41 from being accidentally unlocked.

[0033] Please refer to Figure 6 Furthermore, the end of the sliding pin 41 is provided with a guide surface 43.

[0034] As can be seen from the above description, the presence of the guide surface 43 allows the user to lock the handle 3 without operating the sliding pin 41, further facilitating user operation and enhancing the user experience.

[0035] Please refer to Figures 5 to 7Furthermore, the handle 3 is also provided with an unlocking component 5, which includes a pressing member 51 for pushing the sliding pin 41 out of the lock hole. The handle 3 is provided with a mounting hole 36 communicating with the lock hole, and the pressing member 51 is located at the mounting hole 36.

[0036] As can be seen from the above description, the pressing part 51 on the handle 3 allows the user to unlock the sliding sleeve with one hand.

[0037] Please refer to Figure 6 Furthermore, the unlocking component 5 also includes a second elastic element 52, which connects the handle 3 and the pressing element 51.

[0038] As can be seen from the above description, the second elastic element 52 allows the pressing element 51 to automatically reset.

[0039] 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 device body 10. In the fitness equipment product, the device body 10 is a rod-shaped structural component.

[0040] Please refer to Figures 1 to 4 The sliding sleeve includes a main body 1, a locking element 2, a handle 3, and a locking element 4. The main body 1 has a limiting cavity 11, which is slidably engaged with the device body 10, meaning the sliding sleeve can slide along the device body 10. An avoidance groove 12 is formed on the cavity wall of the limiting cavity 11, and the locking element 2 is slidably disposed in the avoidance groove 12. The locking element 2 is used to lock the relative position between the sliding sleeve and the device body 10. The handle 3 is rotatably connected to the main body 1. The user locks and unlocks the sliding sleeve and the device body 10 by rotating the handle 3. Specifically, when the handle 3 is rotated in one direction, it pushes the locking element 2 along the avoidance groove. 12. The sliding sleeve slides to press against the device body 10. When the handle 3 rotates in the opposite direction, the pressing force of the locking member 2 against the device body 10 is weakened or even disappears, so that the sliding sleeve can slide along the device body 10. The locking member 4 is movably provided on the main body 1. The handle 3 has a mating part 31 that cooperates with the locking member 4. When the locking member 4 cooperates with the mating part 31, the rotation angle of the handle 3 relative to the main body 1 is locked, so that the handle 3 can no longer rotate relative to the main body 1. That is to say, the locking member 4 is used to lock the relative position between the main body 1 and the handle 3, thereby preventing the handle 3 from rotating accidentally, which would cause the device body 10 and the sliding sleeve to be accidentally unlocked.

[0041] Please refer to Figure 4 and Figure 5The clearance groove 12 is preferably a through hole structure. The locking member 2 is located inside the through hole structure. The locking member 2 is limited by the inner peripheral wall of the through hole structure. The locking member 2 is clearance-fitted with the through hole structure. One end of the locking member 2 is stopped by the device body 10, and the other end of the locking member 2 is stopped by the end of the handle 3. Therefore, the locking member 2 cannot be disengaged from the clearance groove 12.

[0042] like Figure 1 and Figure 2 As shown, the main body 1 is provided with a mounting structure 6 for installing accessories, including but not limited to pulley blocks, support arms, and other structural components. Furthermore, the accessories can be either non-detachably connected to the main body 1 or detachably connected, depending on actual needs.

[0043] Please refer to Figures 2 to 5 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.

[0044] Please refer to Figure 2 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 10. The presence of the damping element 7 can prevent the main body 1 from falling unexpectedly and rapidly due to its own weight.

[0045] Please refer to Figure 3 and Figure 4 The handle 3 includes a power arm 32, one end of which is provided with a cam end 33. The cam end 33 abuts against the locking member 2 and extends into the clearance groove 12. In this embodiment, the cam end 33 has a locking surface 331 and an unlocking surface 332 that is angled to the locking surface 331. The locking surface 331 and the unlocking surface 332 are connected by a transition surface 333. The distance from the locking surface 331 to the rotation center axis of the handle 3 is greater than the distance from the unlocking surface 332 to the rotation center axis of the handle 3. Optionally, the locking surface 331 is perpendicular to the unlocking surface 332, and the transition surface 333 is an arc surface.

[0046] In one or more embodiments, the locking member 2 is an elastic structural member, such as a structural member made of rubber, a structural member made of engineering plastic, etc.

[0047] Please refer to Figure 2 , Figure 3 and Figure 7Preferably, the handle 3 includes a gripping arm 34 and multiple power arms 32. The gripping arm 34 connects to each of the power arms 32 and is positioned away from the cam end 33. The main body 1 has multiple clearance grooves 12, each of which is fitted with a locking member 2. The clearance grooves 12 correspond one-to-one with the cam end 33. The gripping arm 34 provides a gripping position for the user and allows the user to simultaneously operate multiple power arms 32 to rotate. Furthermore, when the user slides the sliding sleeve, the user can grip the gripping arm 34 to operate the sliding sleeve. In other embodiments, it is also feasible for the handle 3 to have only one power arm 32, in which case the gripping arm 34 is optional.

[0048] Please refer to Figure 3 and Figure 7 When the number of power arms 32 of the handle 3 is multiple, in some embodiments, the handle 3 further includes a reinforcing arm 35, the reinforcing arm 35 connecting at least two of the power arms 32, and the mating part 31 is provided on the reinforcing arm 35. In this case, it is preferable that the mating part 31 is located in the middle region of the reinforcing arm 35.

[0049] Please refer to Figures 5 to 8 In one or more embodiments, the locking member 4 includes a sliding pin 41, and the mating portion 31 is a lock hole. Preferably, the locking member 4 further includes a first elastic member 42, which connects the sliding pin 41 to the main body 1. The first elastic member 42 can be a spring or the like, and it is used to drive the locking end of the sliding pin 41 to automatically extend and remain in place. In some embodiments, the locking member 4 includes a locking plate with one end rotatably mounted on the main body 1, in which case the mating portion 31 is a lock groove. Alternatively, the locking member 4 can be other structural components with locking functions.

[0050] In this embodiment, the end of the sliding pin 41 is provided with a guide surface 43, which can be an inclined surface, an arc surface, etc.

[0051] Please refer to Figure 3 , Figure 5 and Figure 6To facilitate one-handed operation of the sliding sleeve, the handle 3 is also equipped with an unlocking component 5. The unlocking component 5 includes a pressing member 51 for pushing the sliding pin 41 out of the lock hole. The handle 3 has a mounting hole 36 communicating with the lock hole, and the pressing member 51 is located at the mounting hole 36. Preferably, the unlocking component 5 also includes a second elastic member 52, which connects the handle 3 and the pressing member 51. The second elastic member 52 can be a spring or the like. When the user needs to adjust the position of the sliding sleeve on the device body 10, the user can hold the grip arm 34 with one hand and press the pressing member 51 with the fingers of that hand, while simultaneously rotating the handle 3 to unlock the sliding sleeve from the device body 10. Then, the user slides the sliding sleeve until it is in place, and then rotates the handle 3 in the opposite direction. When the locking member 2 is pressed against the device body 10, the sliding pin 41 automatically inserts into the lock hole. The entire operation is very simple.
