Description

Technical Field

[0001] This application relates to the field of fitness equipment technology, and in particular to a fixing device. Background Technology

[0002] Fitness equipment is typically mounted on the crossbeams or longitudinal beams of a fixed frame, such as a gantry frame, using a fixed device. Users can interact with the equipment, utilizing its power or overcoming its resistance for exercise. The fixed device includes a clamp assembly and a connecting seat. The clamp assembly is used to secure it to the crossbeam or longitudinal beam, and the connecting seat is used to connect the fitness equipment. The clamp assembly has a rotatable connecting member for connecting external equipment (such as fitness ropes) or for user access.

[0020] This application provides a fixing device. Please refer to [link / reference]. Figures 1-4The fixing device 100 may include a clamp assembly 10, a fastening assembly 20, a connecting seat 30, a clamping member 50, and a rotating connecting member 60. The clamp assembly 10 is provided with a receiving space 14 for accommodating an external fixing member. The external fixing member may be a crossbeam or longitudinal beam of a fixing frame such as a gantry frame. The fastening assembly 20 is disposed on the clamp assembly 10 and is configured to fix the clamp assembly 10 to the external fixing member by changing the size of the receiving space 14, so that the fixing device 100 can be adapted to external fixing members of different specifications. The connecting seat 30 is disposed outside the receiving space 14 of the clamp assembly 10 and is connected to the clamp assembly 10. The connecting seat 30 is used to connect to external equipment. The external equipment may be cable-based fitness equipment, which can apply resistance or power to the cable, allowing the user to exercise by reciprocatingly pulling the cable or being propelled by it. A clamping member 50 is disposed between the connecting seat 30 and the clamping assembly 10. The opposing sides of the clamping member 50 abut against the connecting seat 30 and the clamping assembly 10, respectively. A portion of the rotating connecting member 60 is rotatably clamped between the clamping member 50 and the clamping assembly 10. The clamping member 50, disposed between the connecting seat 30 and the clamping assembly 10, forms a sandwich-like layered structure. When the connecting seat 30 is connected to the clamping assembly 10, the clamping member 50 is subjected to compressive forces from both sides, forming a stable clamping area between the clamping member 50 and the clamping assembly 10. A portion of the rotating connecting member 60 is accommodated within this clamping area. The rotatable connection is achieved through the limiting action of the clamping member 50 and the clamping assembly 10, eliminating the need for dedicated shaft mounting holes on the clamping assembly 10 or the connecting seat 30.

[0021] The fixing device 100 provided in this application fixes the rotating connector 60 by clamping the clamping member 50, which avoids secondary processing such as drilling or tapping on the clamping assembly 10, thus reducing processing difficulty and manufacturing cost. In addition, the clamping structure makes it easier to assemble and disassemble the rotating connector 60. The rotating connector 60 can be replaced or maintained after removing the connecting seat 30, which helps to improve the assembly efficiency of the fixing device 100 and the convenience of subsequent maintenance.

[0022] In some embodiments, the clamp assembly 10 may be arranged in a ring shape (not shown in the figure), i.e., it adopts an integral structure. The clamp assembly 10 can be inserted from one end of the external fastener and slide along the external fastener to the predetermined installation position. The integral structure of the clamp assembly 10 has high overall strength, can withstand large loads, and has a simple structure that is easy to form, which helps to reduce manufacturing costs.

[0023] In some embodiments, such as Figures 1-3As shown, the clamp assembly 10 includes a main frame 11 and a base 12. One end of the base 12 is rotatably connected to the main frame 11, and the other end is detachably connected to the main frame 11. The base 12 and the main frame 11 enclose a receiving space 14. The base 12 and the main frame 11 form an "opening and closing" structure. During installation, one end of the base 12 can be opened, making the clamp assembly 10 open, so that it can be fitted onto the predetermined installation position of the external fastener. The split structure allows for easy installation of the clamp assembly 10 at any position on the fastener, and is particularly suitable for pre-assembled gantry frames and other fasteners, improving installation convenience and flexibility.

[0024] In some embodiments, such as Figure 1 , Figure 2 As shown, the fixing device 100 also includes a locking assembly 40. One end of the base 12 is detachably connected to the main frame 11 via the locking assembly 40 to facilitate locking and unlocking between the base 12 and the main frame 11. Exemplarily, the locking assembly 40 may employ a quick-release structure such as a snap-on, wrench, or bolt type to achieve rapid locking and unlocking operations.

[0025] Please see Figure 2 In some embodiments, the connecting seat 30 is located on the side of the base 12 opposite to the main frame 11 and is connected to the base 12. Since the connecting seat 30 is located on the back side of the base 12, during the opening or closing of the clamp assembly 10, the connecting seat 30 is always located on the outside of the base 12, and will not interfere with the main frame 11, nor affect the opening and closing operation of the clamp assembly 10. This allows the connecting seat 30 and the base 12 to be installed or disassembled as a whole module, without the need to adjust the position of the connecting seat 30 after the clamp assembly 10 is installed, which further simplifies the operation steps.

[0026] In some embodiments, such as Figures 2-5 As shown, the base 12 is provided with a first mounting groove 124, and the clamping member 50 is at least partially embedded in the first mounting groove 124. One end of the connecting seat 30 abuts against one side of the clamping member 50 and is partially embedded in the first mounting groove 124. With this arrangement, the clamping member 50 and one end of the connecting seat 30 are partially embedded in the first mounting groove 124 of the base 12. On the one hand, the clamping member 50 and the base 12 partially overlap in the opening direction of the first mounting groove 124, which helps to reduce the overall size of the fixing device 100 in this direction and achieve a compact design. On the other hand, the force direction of the connecting seat 30 is usually the same as the opening direction of the first mounting groove 124. The first mounting groove 124 needs to accommodate the clamping member 50 and has a large groove wall height, which helps to ensure the tensile strength of the base 12. In addition, the groove wall of the first mounting groove 124 is used to radially limit the connecting seat 30, which can realize the rapid positioning of the connecting seat 30 and the base 12, facilitate assembly, and improve production efficiency.

[0027] In some embodiments, the base 12 may not have the first mounting groove 124. In this case, the side of the base 12 facing the connecting seat 30 is roughly plate-shaped, which makes the shape of the base 12 more regular and helps to simplify the processing of the base 12.

[0028] Please see Figures 2-7 In some embodiments, the base 12 is further provided with a second mounting groove 125. The clamping member 50 includes a clamping plate 51 and a protruding rib 52. The protruding rib 52 protrudes from the side of the clamping plate 51 facing the base 12 and is embedded in the second mounting groove 125. A third mounting groove 521 corresponding to the second mounting groove 125 is provided on the protruding rib 52. The rotating connector 60 includes a rotating shaft 61 and an annular portion 62 fixedly connected to both ends of the rotating shaft 61. The rotating shaft 61 and the annular portion 62 can be assembled or integrally formed. The rotating shaft 61 is rotatably disposed in the second mounting groove 125 and the third mounting groove 521. With this configuration, the rib 52 protrudes from the clamping plate 51 and is embedded in the second mounting groove 125, and the mounting area of ​​the rotating connector 60 is concentrated in the local position where the rib 52 is located. On the one hand, the rib 52 can locally increase the structural thickness of the clamping plate 51 in this area, and strengthen the overall strength of the clamping member 50 due to the opening of the third mounting groove 521, which is conducive to improving the structural strength of the clamping member 50 at the mounting position of the rotating connector 60. On the other hand, the rib 52 only protrudes locally, and the other areas of the clamping plate 51 remain relatively thin, which is conducive to reducing the overall volume and weight of the clamping member 50 and achieving a compact design.

[0029] In some embodiments, such as Figures 2-7As shown, the connector 30 is cylindrical. The clamping member 50 also includes a protrusion 53, which is located on the side of the clamping plate 51 opposite to the rib 52 and is embedded in the hollow area of ​​the connector 30. The clamping plate 51 has a fourth mounting groove 531 in the area where the protrusion 53 is located, and the fixing device 100 also includes a magnetic element 70 disposed in the fourth mounting groove 531. The magnetic element 70 can be used to trigger the detection element (not shown) of the external device to generate an installation status signal when the external device is installed to the connector 30, so that the external device can lock the connection with the connector 30 based on the installation status signal, which helps to reduce the risk of the external device falling off. For example, the magnetic element 70 can be a magnet, and the detection element can be a Hall element. With this configuration, the protrusion 53 protrudes from the clamping plate 51 and is embedded in the hollow area of ​​the connecting seat 30. The area where the protrusion 53 is located has a relatively large thickness, which can provide space for the fourth mounting groove 531 to accommodate the magnetic component 70. On the one hand, since the protrusion 53 is embedded in the hollow area of ​​the connecting seat 30, the internal space of the connecting seat 30 can be fully utilized, so that the installation of the magnetic component 70 does not require additional increase in the overall thickness of the clamping component 50, nor does it increase the overall size of the fixing device 100 in this direction, which is conducive to achieving a compact design. On the other hand, the protrusion 53 can locally increase the structural thickness of the clamping plate 51 in this area, which can compensate for the weakening of the overall strength of the clamping plate 51 caused by the opening of the fourth mounting groove 531, and help improve the structural strength of the clamping plate 51 at the mounting location of the connecting seat 30.

[0030] Please see Figures 2-7 In some embodiments, the rotating connector 60 further includes an elastic bushing 63. The elastic bushing 63 is fixedly disposed between the base 12 and the clamping member 50, and sleeved around the outer periphery of the rotating shaft 61. The elastic bushing 63 can be made of rubber, silicone, or other elastic materials. The elastic bushing 63 can provide elastic support when the rotating shaft 61 rotates, absorbing vibrations and noise generated during rotation, which helps to improve the comfort and durability of the rotating connector 60; at the same time, the elastic bushing 63 can also apply a certain preload to the rotating shaft, so that the rotating shaft 61 has a certain damping feel when rotating, preventing the rotating connector 60 from shaking freely after the external force is removed. One of the base 12 and the protruding rib 52 includes a locking protrusion 123, and the other has a locking groove 522. The locking protrusion 123 engages with the locking groove 522, so that the elastic bushing 63 and the clamping member 50 can be pre-assembled with the base 12 and then connected to the connecting seat 30 by the fastening connector 13. With this setup, the elastic bushing 63 and the clamping part 50 are temporarily fixed to the base 12 before final locking, preventing displacement or detachment. This is suitable for automated production lines or assembly scenarios with multiple processes, which helps simplify assembly operations and improve assembly efficiency.

[0031] In some embodiments, such as Figures 2-7As shown, the clamping member 50 also includes two extension portions 54, which are connected to opposite ends of the clamping plate 51 along the extension direction of the rib 52. The two extension portions 54 are located outside the connecting seat 30. There are two elastic bushings 63, which are respectively disposed between the base 12 and the two extension portions 54. This arrangement, with the extension portions 54 extending outward along the extension direction of the rib 52, increases the axial dimension of the clamping member 50 in the rotating shaft 61, which helps improve the structural strength of the clamping member 50 in the mounting area of ​​the rotating connector 60, further enhancing the reliability of the clamping member 50. Furthermore, the two elastic bushings 63 are respectively disposed between the base 12 and the two extension portions 54, i.e., at the outermost ends of the clamping member 50. During assembly, the elastic bushings 63 can be directly pushed into the gap between the base 12 and the extension portions 54 from both ends, without needing to pass through the middle area of ​​the clamping member 50. This simplifies the installation operation of the elastic bushings 63 and improves assembly efficiency.

[0032] Please see Figure 1 , Figures 4-7 In some embodiments, the outer periphery of the connecting seat 30 is provided with a plurality of snap-fit ​​grooves 31 for connecting external devices at circumferential intervals. The base 12 includes a seat body 121 and a plurality of positioning protrusions 122. A first mounting groove 124 is disposed in the seat body 121, and the plurality of positioning protrusions 122 are respectively disposed in the inner wall of the first mounting groove 124. The outer periphery of the clamping member 50 is provided with a plurality of clearance grooves 511 at circumferential intervals. The plurality of positioning protrusions 122 are respectively accommodated in the corresponding plurality of clearance grooves 511 and the plurality of snap-fit ​​grooves 31. By the positioning protrusions 122 engaging with the clearance grooves 511 and the snap-fit ​​grooves 31, the circumferential assembly and positioning of the base 12, the clamping member 50 and the connecting seat 30 can be realized. This configuration allows the snap-fit ​​groove 31 to simultaneously perform assembly positioning functions, eliminating the need for an additional dedicated positioning structure on the connector 30. This simplifies the overall structure of the connector 30 and reduces manufacturing costs. Furthermore, since the snap-fit ​​groove 31 is used to connect external devices, its machining precision is typically high. Utilizing the high precision of the snap-fit ​​groove 31 improves the assembly precision among the base 12, the clamping member 50, and the connector 30, ensuring accurate circumferential alignment of all components and enhancing the overall assembly precision of the fixing device 100.

[0033] In some embodiments, such as Figure 4As shown, the clamp assembly 10 also includes a fastening connector 13, which passes through the base 121 and the clamping member 50 and connects to the connecting seat 30. Exemplarily, the fastening connector 13 can be a fastener such as a screw, bolt, or stud. With this configuration, the fastening connector 13 simultaneously connects the base 12's base 12, the clamping member 50, and the connecting seat 30, locking them together at once. This eliminates the need for separate connection structures for each component, simplifying the overall structure of the fixing device 100, reducing the number of parts, and lowering assembly complexity.

[0034] Please see Figure 4 In some embodiments, a fastening connector 13 is provided on each side of each snap-fit ​​groove 31. The snap-fit ​​groove 31 is the main connection part between the connector 30 and the external device, and it bears a large tensile force or impact load during use. By setting the fastening connector 13 on both sides of the snap-fit ​​groove 31, a direct locking force can be provided near the stress area of ​​the snap-fit ​​groove 31, so that the locking force of the fastening connector 13 can act most effectively on the stress-concentrated part, which helps to improve the connection reliability between the connector 30 and the base 12 and avoids loosening or failure due to excessive local stress.

[0035] In some embodiments, the connector 30 is a metal part, while the main frame 11, base 12, and clamping member 50 are all plastic parts. As a component directly connected to external equipment, the connector 30 withstands significant tensile or impact loads during use. Being made of metal provides high structural strength and wear resistance, which helps ensure the reliability of the connection between the connector 30 and the external equipment and extends its service life. For example, the connector 30 can be made of aluminum alloy, zinc alloy, or stainless steel. Making the main frame 11, base 12, and clamping member 50 all plastic parts allows for efficient and low-cost injection molding, reducing the overall manufacturing cost of the fixing device 100. Furthermore, the lightweight nature of plastic parts helps reduce the overall weight of the fixing device 100, facilitating handling and installation. For example, the main frame 11, base 12, and clamping member 50 can be made of nylon, polyoxymethylene (POM), glass fiber reinforced nylon, or ABS.
