Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment accessories, and in particular to a fixing member. Background Art

[0002] When using fitness equipment, the user will interact with the fitness equipment, use the power of the fitness equipment or overcome the resistance of the fitness equipment to exercise. Since the fitness equipment itself needs to apply power or resistance to the user, the fitness equipment usually needs to be fixed. In the prior art, a gantry or other fixing parts are usually used as a frame to fix the fitness equipment on the frame.

[0003] However, the fitness equipment industry lacks various standards, resulting in the existence of racks of different manufacturers and models on the market. The cross-sectional aspect ratios and length-to-width dimensions of these racks are also different. Therefore, the problem of fixing fitness equipment on different racks has never been solved. The prior art lacks a rack fixing solution that can adapt to cross-sections of different sizes. Summary of the invention

[0055] See also Figure 1 and Figure 2 A fixing member 100 according to an embodiment of the present application includes an outer frame 10, a clamping block 20 and an adjusting locking mechanism 30. An accommodating space 110 is opened inside the outer frame 10. The clamping block 20 is partially or completely movably arranged on the inner side of the outer frame 10. The adjusting locking mechanism 30 is used to adjust the position of the clamping block 20 relative to the outer frame 10 and lock it.

[0056] In the fixing member 100 of the embodiment of the present application, the adjusting locking mechanism 30 can adjust the position of the clamping block 20 relative to the outer frame 10 to control the size of the internal accommodating space 110 of the outer frame 10, so that the fixing member 100 can be locked on the rack with different cross-sectional sizes. The operation is relatively simple. At the same time, the fitness equipment can be adapted to racks of different models through the fixing member 100, and replacement is more convenient.

[0057] Specifically, the fixing member 100 can be used to fix the fitness equipment. That is, the user can first clamp the fixing member 100 on the frame, and then assemble the fitness equipment on the fixing member 100, and then the user can use the fitness equipment to exercise. When the user wants to change the position for exercise, the fixing member 100 can be replaced to the position where the user wants to exercise, and then the user can exercise quickly and conveniently in different positions.

[0058] The outer edge of the outer frame 10 can be set to a square structure or a circular structure, etc., and the present application does not limit the outer edge structure of the outer frame 10. The central area of ​​the outer frame 10 is set through, that is, forming an accommodating space 110 inside the outer frame 10. The accommodating space 110 can be square, circular or other shapes, which are compatible with the cross-sectional shape of the frame so that it can be clamped on the frame more tightly.

[0059] Part or all of the pressing block 20 is movably disposed inside the accommodating space 110, and the adjusting locking mechanism 30 is fixedly disposed on the outer frame 10. The pressing block 20 and the adjusting locking mechanism 30 are connected and matched, so that the pressing block 20 can adjust the position of the pressing block 20 relative to the outer frame 10 under the adjustment of the adjusting locking mechanism 30, that is, adjust the position of part or all of the pressing block 20 located in the accommodating space 110, thereby changing the size of the accommodating space 110, so that the accommodating space 110 fits the fixing member 100, and thus the fixing member 100 can be stably and firmly assembled on the frame.

[0060] like Figure 3 As shown, it should be noted that the shape of the clamping block 20 toward the inner side of the accommodating space 110 can be angular, arc-shaped, convex, top block-shaped, groove-shaped, etc., and may not match the shape of the accommodating space 110, or may match the shape of the accommodating space 110, thereby being able to better cooperate with the outer frame 10 to clamp the frame.

[0061] The adjustment locking mechanism 30 may include any structure with an adjustment function, for example, a structure that drives the pressing block 20 to move by rotating a screw, or a structure that drives the pressing block 20 to move by a telescopic rod, etc. The present application does not limit the specific structure and adjustment method of the adjustment locking mechanism 30, and it only needs to be able to adjust the position of the pressing block 20 relative to the outer frame 10 to lock the fixing member 100 on the frame.

[0062] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the outer frame 10 includes at least two frame units 11 connected in sequence, and adjacent frame units 11 are connected to each other through a hinge structure 41 or a quick-release structure 42. Two or more frame units 11 are connected end to end in sequence and enclose a receiving space 110.

[0063] In this way, the outer frame 10 is connected by a hinged or quick-release manner using multiple frame units 11, making the installation and removal of the fixing member 100 relative to the rack more convenient and quick, and also making the adaptability between the outer frame 10 and the rack higher, thereby improving the user experience.

[0064] Specifically, the outer frame 10 units may include two, three or four, etc. At least two outer frame 10 units are connected end to end to enclose the internal accommodation space 110. The adjacent two outer frame 10 units may be hingedly connected using an axle pin structure or other structures, or may be quickly disconnected using a lock or other structures. Figure 4 As shown, for example, a circular storage space 110 is formed by two semicircular frame units 11; a rectangular storage space 110 is formed by two L-shaped frame units 11; a circular or elliptical storage space 110 is formed by a plurality of arc-shaped frame units 11; a rectangular storage space 110 is formed by a plurality of L-shaped frame units 11 and a plurality of long strip frame units 11, etc. Preferably, two adjacent outer frame units 10 include at least one quick-release structure 42 for connection, thereby facilitating installation and removal of the fixing member 100 on the rack.

[0065] In the implementation manner of the present application, two outer frame 10 units are taken as an example for explanation, but those skilled in the art will appreciate that the technical solution in the implementation manner of the present application is applicable to fixing parts 100 in which more outer frame 10 units are interconnected. In the present application, one end of the two outer frame 10 units is hingedly connected by an axle pin structure, and the other end is connected by a quick-release structure 42.

[0066] See also Figure 5 and Figure 6 In some embodiments, the quick-release structure 42 includes: a telescopic pin 421 and a plug-in hole 422, the telescopic pin 421 is arranged at the end of a frame unit 11, the telescopic pin 421 is elastically pushed outward from the end of the frame unit 11, and the plug-in hole 422 is arranged at the end of an adjacent frame unit 11, and the plug-in hole 422 is arranged corresponding to the telescopic pin 421, wherein the direction of the plug-in hole 422 and the telescopic pin 421 is the same as the hinge direction of the two frame units 11.

[0067] In this way, when the telescopic pin 421 is inserted into the plug-in hole 422, the two frame units 11 can be locked and connected; pressing the telescopic pin 421 can retract the telescopic pin 421, thereby controlling the connection between the telescopic pin 421 and the plug-in hole 422, so that the connecting ends of the two frame units 11 are connected or separated, thereby realizing the rapid disassembly of the fixing frame.

[0068] Specifically, there are two retractable pins 421, and the ejection directions are opposite, and they are respectively connected with the two plug holes 422 of the adjacent frame units 11. The end of one of the frame units 11 can be provided with a mounting portion 111, and the mounting portion 111 is provided with a through mounting hole 1111, and the two retractable pins 421 are installed back to back in the mounting hole 1111. The two retractable pins 421 arranged opposite to each other can make the connection between the adjacent frame units 11 more stable, and the user can press the two retractable pins 421 relatively to retract them at the same time, which is more convenient to operate.

[0069] Specifically, an elastic member may be provided in the mounting hole 1111, and the elastic member can elastically push the telescopic pin 421 outward. When there are two telescopic pins 421, the elastic member can provide elastic force to simultaneously push the two telescopic pins 421 out of the mounting hole 1111 in opposite directions.

[0070] Specifically, the ends of the adjacent frame units 11 may be provided with avoidance positions 112 matched with the mounting portions 111 , and opposite sides of the avoidance positions 112 are respectively provided with plugging holes 422 , and the shapes of the plugging holes 422 are matched with the shapes of the telescopic pins 421 .

[0071] When the two frame units 11 need to be locked and connected, the telescopic pin 421 is pressed to retract the telescopic pin 421 into the mounting hole 1111, and then the mounting portion 111 is moved to the avoidance position 112, and the telescopic pin 421 is released so that the telescopic pin 421 is pushed out of the mounting hole 1111 and extends into the plug-in hole 422, thereby realizing the locking connection of the two frame units 11. Similarly, when the two frame units 11 need to be separated, the telescopic pin 421 is pressed to withdraw the telescopic pin 421 from the plug-in hole 422 and retract it into the mounting hole 1111, and then the mounting portion 111 is moved out of the avoidance position 112, thereby realizing the separation of the two frame units 11. Furthermore, the quick-release structure 42 of the embodiment of the present application can realize the rapid locking and separation of the two frame units 11, simplifying the installation and disassembly of the fixing member 100, which is convenient and quick.

[0072] See also Figure 5 and Figure 6 In some embodiments, a guiding slope 4211 is provided at the end of the telescopic pin 421. The guiding slope 4211 may be formed at the end of the telescopic pin 421 extending out of the mounting hole 1111, and the guiding slope 4211 may be oriented toward the avoidance position 112.

[0073] Thus, when the two frame units 11 need to be locked and connected, when the mounting portion 111 moves toward the avoidance position 112, the telescopic pin 421 can be directly pressed back into the mounting hole 1111 through the cooperation between the avoidance position 112 and the guiding slope 4211, and the telescopic pin 421 can be pressed back without actively pressing the telescopic pin 421. When the telescopic pin 421 moves to the insertion hole 422, it can be pushed out and inserted into the insertion hole 422, thereby achieving the locking of the two.

[0074] See also Figure 5 and Figure 6 In some embodiments, an unlocking button 423 is movably provided in the plug hole 422 for contacting the telescopic pin 421. The unlocking button 423 can move between a first position where it presses the telescopic pin 421 to retract and a second position where it contacts the telescopic pin 421 when it is pushed out.

[0075] In this way, the retractable pin 421 can be retracted into the mounting hole 1111 by pressing the unlocking button 423 to achieve rapid unlocking of the two frame units 11 .

[0076] Specifically, the unlocking button 423 is movably installed in the plug hole 422, and can slide between a first position and a second position in the plug hole 422. When the unlocking button 423 is in the first position, that is, when the unlocking button 423 is pressed in the direction of the telescopic pin 421, the unlocking button 423 can push the telescopic pin 421 out of the plug hole 422 and retract it into the mounting hole 1111; when the unlocking button 423 is in the second position, that is, when the unlocking button 423 is not pressed, the unlocking button 423 is lifted under the support of the telescopic pin 421, and the frame unit 11 is in a locked state or a disconnected state.

[0077] See also Figure 7 and Figure 8 In some embodiments, one of the plug-in hole 422 and the unlocking button 423 is provided with a compression groove 4232 along the busbar direction and a rotation groove 4233 along the circumferential direction in the plane where the two slide, and the compression groove 4232 and the rotation groove 4233 are communicated with each other, and the other of the plug-in hole 422 and the unlocking button 423 is provided with a limiting protrusion 19, and the limiting protrusion 19 slides in the compression groove 4232 or the rotation groove 4233. When the telescopic pin 421 is inserted into the plug-in hole 422, the limiting protrusion 19 is located in the rotation groove 4233.

[0078] In this way, the unlocking button 423 can slide in a limited position through the cooperation of the compression groove 4232 and the limiting protrusion 19, and can be locked and pressed through the cooperation of the rotation groove 4233 and the limiting protrusion 19, thereby preventing the unlocking button 423 from being accidentally touched during fitness exercises, causing the frame unit 11 to be unlocked and causing harm to the user.

[0079] Specifically, the unlocking button 423 may be a columnar structure, and can rotate and move within the plug-in hole 422 .

[0080] In one embodiment, the outer wall of the unlocking button 423 is provided with a compression groove 4232 and a rotation groove 4233, the compression groove 4232 extends along the pressing direction of the unlocking button 423, the rotation groove 4233 extends along the axis direction of the unlocking button 423, and the rotation groove 4233 is located at the end of the compression groove 4232 close to the telescopic pin 421. In other words, it can be understood that the compression groove 4232 and the rotation groove 4233 are connected in an "L" shape on the outer wall of the unlocking button 423. Correspondingly, a limiting protrusion 19 is correspondingly provided on the inner wall of the plug hole 422, and the limiting protrusion 19 can extend into the compression groove 4232 and the rotation groove 4233.

[0081] When the limiting protrusion 19 is located in the compression groove 4232, the unlocking button 423 can move vertically in the pressing direction under the cooperation of the limiting protrusion 19 and the compression groove 4232. At this time, the unlocking button 423 can be used to unlock the frame unit 11 normally.

[0082] When the frame unit 11 is in the locked state, the limiting protrusion 19 is at the end of the compression groove 4232 close to the telescopic pin 421, that is, the connection between the compression groove 4232 and the rotation groove 4233. At this time, the rotation of the unlocking button 423 causes the limiting protrusion 19 to move along the rotation groove 4233 in a direction away from the compression groove 4232, and then under the restriction of the limiting protrusion 19 and the rotation groove 4233, the unlocking button 423 cannot be pressed, that is, the press locking of the unlocking button 423 is achieved, and the accidental touching of the unlocking button 423 can be avoided. When the position of the fixing member 100 needs to be changed, the limiting protrusion 19 can be moved back to the telescopic groove by rotating the unlocking button 423 to press and unlock.

[0083] Of course, in another embodiment, the compression groove 4232 and the rotation groove 4233 may be provided on the inner wall of the plug hole 422, and the limiting protrusion 19 may be provided on the unlocking button 423. The present application does not limit whether the compression groove 4232, the rotation groove 4233 and the limiting protrusion 19 are provided on the unlocking button 423 or on the plug hole 422.

[0084] See also Fig. 9 and Fig.10 In some embodiments, the frame unit 11 on which the telescopic pin 421 is provided is also movably provided with a locking spring piece 12, and a locking protrusion 4231 is provided around the unlocking button 423. When the telescopic pin 421 is inserted into the plug-in hole 422, the locking spring piece 12 acts on the locking protrusion 4231 and prevents the unlocking button 423 from pressing the telescopic pin 421. The locking spring piece 12 has an elastic force to rotate in the direction of the locking protrusion 4231.

[0085] In this way, the unlocking button 423 can be locked and pressed under the restriction of the locking spring piece 12 and the locking protrusion 4231, providing a double layer of insurance to prevent the frame unit 11 from being accidentally unlocked. When unlocking is required, only the locking spring piece 12 needs to be pressed so that the locking spring piece 12 overcomes the elastic force and leaves the locking protrusion 4231. At this time, the unlocking button 423 can be pressed to unlock the connection of the frame unit 11.

[0086] See also Fig. 9 and Fig.10 In some embodiments, the frame unit 11 having the plug-in hole 422 is provided with a locking groove 13 connected to the plug-in hole 422, and the locking spring piece 12 partially extends into the locking groove 13, and the portion can act on the locking protrusion 4231. By adding the locking groove 13 and allowing the locking spring piece 12 to move in the locking groove 13, the locking stability can be improved and the installation space can be saved. Exemplarily, the locking groove 13 is opened at the end of the frame unit 11 having the plug-in hole 422 and faces the end of the adjacent frame unit 11, so that the locking spring piece 12 of the adjacent frame unit 11 can be inserted through and act on the locking protrusion 4231.

[0087] like Figure 1 As shown, in some embodiments, the frame unit 11 provided with the locking spring sheet 12 is provided with an outer frame handle 14 .

[0088] In this way, the user can hold the outer frame handle 14 to press the locking spring piece 12, which facilitates the pressing of the locking spring piece 12. At the same time, the setting of the outer frame handle 14 also improves the stability of the user when installing and removing the fixing member 100 to avoid falling.

[0089] Specifically, the outer frame handle 14 can be extended along the length direction of the frame unit 11, and the locking spring 12 is located at the end side of the outer frame handle 14. When the user holds the outer frame handle 14, the thumb can be used to press the locking spring 12, so that there is a good force point when pressing the locking spring 12. At the same time, through this arrangement, the user can hold the fixing member 100 and press the locking spring 12 with one hand at the same time, and the other hand only needs to press the unlocking button 423 to complete the quick connection or separation of the frame unit 11, which is more convenient to operate.

[0090] See also Figure 1 , Figure 5 and Fig.11 In some embodiments, the fixing member 100 further includes a pre-tightening device 50 , which is on the outer frame 10 and can provide pre-tightening pressure to the accommodating space 110 .

[0091] In this way, during the installation of the fixing member 100, when the size of the accommodating space 110 inside the outer frame 10 is relatively loose relative to the cross-section of the frame, the pre-tightening device 50 can provide a certain tightening force in the direction of the frame to prevent the fixing member 100 from slipping, thereby facilitating the adjustment of the position of the clamping block 20.

[0092] Exemplarily, the pre-tightening device 50 includes a pre-tightening block 51 and a pre-tightening spring 52 . The pre-tightening block 51 is located inside the outer frame 10 . The pre-tightening spring 52 is used to elastically push the pre-tightening block 51 inward, thereby realizing a solution of providing pre-tightening pressure to the accommodating space 110 .

[0093] Specifically, the pre-tightening device 50 works and produces a pre-tightening effect before the clamping block 20 is locked in the accommodating space 110, mainly to prevent the fixing member 100 from sliding downward due to its own gravity when the clamping block 20 is not locked on the clamping frame.

[0094] Further, the pre-tightening block 51 can be arranged inside the accommodating space 110 of the outer frame 10, and the pre-tightening spring 52 is arranged between the pre-tightening block 51 and the outer frame 10. When the outer frame 10 is clamped on the frame, the pre-tightening block 51 is pushed out toward the frame under the elastic action of the pre-tightening spring 52, so that a certain friction force is generated between the inner wall of the accommodating space 110 and the frame, thereby preventing the fixing member 100 from sliding relative to the frame.

[0095] It should be noted that the pre-tightening spring 52 squeezes the pre-tightening block 51 so that the friction force formed between the inner side of the accommodating space 110 and the frame is greater than the gravity of the fixing member 100. At the same time, the elastic force of the pre-tightening spring 52 squeezing the pre-tightening block 51 is smaller than the pressing force of the pressing block 20, that is, the pre-tightening device 50 mainly plays an auxiliary pressing role before the pressing block 20 is pressed, and the main pressing force of the fixing member 100 is the force generated by the adjusting locking mechanism 30 to adjust the pressing block 20 to the inside of the accommodating space 110.

[0096] like Fig.11 As shown, in some embodiments, the outer frame 10 is provided with a sliding groove 15 , and the pre-tightening device 50 is slidably arranged in the sliding groove 15 .

[0097] In this way, the pre-tightening device 50 can adjust the position of releasing the pre-tightening force into the accommodating space 110 by sliding in the sliding groove 15, so that the pre-tightening device 50 can be squeezed with the frame at a suitable position to avoid loosening due to insufficient pre-tightening.

[0098] Specifically, the sliding groove 15 is disposed on the inner side of the outer frame 10 , with the groove opening facing the inside of the accommodating space 110 , and the pre-tightening block 51 is slidably disposed in the sliding groove 15 .

[0099] Furthermore, the pre-tightening device 50 damps the sliding in the sliding groove 15, that is, the sliding of the pre-tightening device 50 has a certain resistance, so that the user can more easily adjust the position of the pre-tightening device 50 in the sliding groove 15 and can slide it to the desired position more accurately.

[0100] like Figure 5 and Fig.11 As shown, in some embodiments, the preload block 51 may include a slider 512 and a pressure block 511. A pressure groove is formed inside the slider 512, with the groove opening facing the accommodating space 110. The pressure block 511 is movably arranged in the pressure groove. The preload spring 52 is also assembled in the pressure groove and is located between the pressure block 511 and the bottom of the pressure groove to provide an elastic force for the pressure block 511 to be ejected in the direction of the accommodating space 110.

[0101] The slider 512 is slidably disposed in the sliding groove 15. A damping structure may be disposed between the slider 512 and the sliding groove 15 to increase the friction between the slider 512 and the sliding groove 15, and to prevent the preload device 50 from sliding arbitrarily in the sliding groove 15 and affecting the preload effect. For example, a plurality of convex points and a plurality of corresponding concave pits are respectively disposed on the surfaces where the slider 512 and the sliding groove 15 are in sliding contact. The present application does not limit the damping structure.

[0102] like Figure 5 and Fig.11 As shown, in some embodiments, the pre-tightening device 50 further includes an unlocking handle 53, and the unlocking handle 53 is used to pull the pre-tightening block 51 or the pre-tightening spring 52 outward to release the pre-tightening pressure.

[0103] In this way, the pre-tightening device 50 can release the pre-tightening force of the pre-tightening block 51 toward the accommodating space 110 by pulling the unlocking handle 53, which is convenient for adjusting the position of the fixing member 100 on the same frame and also convenient for disassembly and installation of the fixing member 100.

[0104] When the user needs to adjust the position on the same rack, after loosening the clamping block 20, the pre-tightening device 50 has a pre-tightening force in the direction of the rack to stabilize the fixing member 100, so that the fixing member 100 will have a certain resistance when moving on the rack. When the user wants to adjust the position of the fixing member 100 on the rack over a long distance, the pre-tightening block 51 can be pulled up by unlocking the handle 53 to remove the pre-tightening force, so that the fixing member 100 can move on the rack more smoothly.

[0105] When the user needs to remove the fixing part 100, due to the effect of the pre-tightening force, the quick-release structure 42 will also be tightened, and there will be a large friction between the telescopic pin 421 and the plug-in hole 422, so that there will be a certain resistance when pressing the unlocking button 423. At this time, the pre-tightening block 51 can also be pulled up through the unlocking handle 53 to remove the pre-tightening force, thereby facilitating the removal of the fixing part 100.

[0106] Specifically, when the pre-tightening device 50 is fixedly disposed on the outer frame 10 , the unlocking handle 53 is movably disposed on the outer frame 10 ; when the pre-tightening device 50 is slidably disposed on the outer frame 10 , the unlocking handle 53 is movably disposed on the slider 512 .

[0107] See also Figure 5 and Fig.11 In some embodiments, the outer frame 10 is further provided with an outer frame handle 14 , and the outer frame handle 14 and the pre-tightening device 50 are located on the same side of the outer frame 10 .

[0108] In this way, the user can use the outer frame handle 14 as a support point to pull the unlocking handle 53 to facilitate the removal of the pre-tightening force. Specifically, when holding the outer frame handle 14, the user can pull the unlocking handle 53 with four fingers without performing additional operations on the unlocking handle 53. The actions of holding the outer frame handle 14 and pulling the unlocking handle 53 can be completed with one hand. The setting of the outer frame handle 14 also enables the user to better grasp the fixing part 100, thereby improving the safety of use.

[0109] See also Figure 2 and Fig.12 In some embodiments, the preload device 50 further includes an unlocking button 54, and the movable direction of the unlocking button 54 is different from the movable direction of the preload block 51. At least one of the unlocking button 54 and the preload block 51 is provided with a sliding wedge, and the sliding wedge is used to slide in contact with the other. When the unlocking button 54 is pressed, the preload block 51 retracts.

[0110] In this way, the pre-tightening device 50 can release the pre-tightening force of the pre-tightening block 51 in the direction of the accommodating space 110 by pressing the unlocking button 54, which is convenient for adjusting the position of the fixing part 100 on the same frame. At the same time, pressing the unlocking button 54 can also grasp the fixing part 100, which is convenient for disassembly and installation of the fixing part 100. This scheme provides another scheme for unlocking the pre-tightening device 50; specifically, the unlocking button 54 can be set on the outer frame 10, or on the frame unit 11.

[0111] See also Fig.11 and Fig.13 In some embodiments, the adjustment locking mechanism 30 includes an adjustment handle 31, an adjustment screw 32, and an adjustment nut 33; the adjustment handle 31 is rotatably arranged on the outer frame 10, and one of the adjustment screw 32 and the adjustment nut 33 is connected to the adjustment handle 31, and the other is connected to the clamping block 20. The adjustment screw 32 and the adjustment nut 33 cooperate with each other, and fixing one of them and rotating the other will change the distance between the two, and then by rotating the adjustment nut 33, the clamping block 20 can be moved away from or close to the adjustment nut 33 to complete the adjustment. Furthermore, a self-locking thread can be used to achieve a locking effect after adjustment.

[0112] See also Figure 2and Fig.14 In some embodiments, a mark is provided on the clamping block 20 or the adjusting nut 33 or the adjusting screw 32 connected to the clamping block 20; the outer frame 10 is provided with a scale 17 and an observation window 18, which are arranged corresponding to the mark. By turning the adjusting handle 31, the clamping block 20 can be moved away from or closer by adjusting the nut 33 and the adjusting screw 32, and the mark connected to the clamping block 20 can move at the same time. By providing the scale 17 and the observation window 18 on the outer frame 10, the change of the mark can be intuitively observed inward, thereby providing guidance for the user.

[0113] See also Fig.13 and Fig.14 In some embodiments, the adjustment handle 31 includes a coaxially arranged outer handle 311 and a protective block 312, and the end surface of the outer handle 311 in contact with the protective block 312 is provided with a plurality of first inclined surfaces 341 with varying heights along the circumferential direction and a first step 343 connecting the plurality of inclined surfaces; the end surface of the protective block 312 in contact with the outer handle 311 is provided with a second inclined surface 342 and a second step 344 corresponding to the outer handle 311. Assuming that the first direction is the locking direction and the second direction is the loosening direction, when the outer handle 311 is rotated in the first direction, the outer handle 311 can push the second inclined surface 342 of the protection block 312 through the friction force of the first inclined surface 341, thereby driving the protection block 312 to rotate, and driving the adjusting screw 32 or the adjusting nut 33 to rotate, at this time the clamping block 20 moves inward; when the clamping block 20 locks the frame, it cannot move inward, the adjusting screw 32 and the adjusting nut 33 cannot move relative to each other, that is, the protection block 312 cannot rotate. At this time, the first inclined surface 341 cannot drive the second inclined surface 342 through the friction force. If the outer handle 311 is continued to be rotated in the first direction with force, the outer handle 311 will slide between the protection block 312, thereby achieving over-force protection; when the outer handle 311 is rotated in the second direction, at this time the outer handle 311 directly acts on the second step 344 through the first step 343, thereby driving the protection block 312 to rotate, and completing the unlocking.

[0114] See also Fig.13 and Fig.14 In some embodiments, one of the first inclined surface 341 and the second inclined surface 342 is provided with a positioning bead 345, and the other is provided with a positioning groove 346; or the first inclined surface 341 and the second inclined surface 342 are provided with positioning beads 345 and positioning grooves 346 that correspond to each other on the other inclined surface. On the one hand, the positioning beads 345 and the positioning grooves 346 can generate a greater mutual force when the first inclined surface 341 and the second inclined surface 342 do not slide, and on the other hand, when the first inclined surface 341 and the second inclined surface 342 slide, the sliding friction between the two can be eliminated to prevent sliding wear between the two.

[0115] See also Figure 5In some embodiments, the outer frame 10 is provided with a guide groove 16, and the clamping block 20 is completely or partially located in the guide groove 16. The guide groove 16 is used to guide the clamping block 20 to slide and prevent it from rotating. The guide groove 16 can also provide guidance for the clamping block 20 to make it slide more smoothly on the outer frame 10. In some embodiments, the outer frame 10 is composed of a plurality of frame units 11 connected to each other. In this case, the guide groove 16 can be provided on the frame unit 11.

[0116] See also Figure 5 In some embodiments, the pressing block 20 includes a pressing seat 21 and a replacement block 22; the pressing seat 21 is connected to the adjustment locking mechanism 30 and is movably arranged inside the outer frame 10; the replacement block 22 is detachably connected to the pressing block 20. By modularizing the pressing block 20, the user can replace the replacement block 22 in contact with the outer frame 10 by himself, thereby improving the interchangeability and service life of the device.

[0117] See also Figure 3 and Figure 5 In some embodiments, there are at least two replacement blocks 22, and at least one of the shapes or sizes of the replacement blocks 22 is different. Due to different usage scenarios of users, the fixing member 100 may be fixed on the outer frame 10 with different cross-sectional shapes. Then, by equipping a plurality of replacement blocks 22 with different shapes, the user can select a replacement block 22 with high adaptability for use according to the scenario in which he is in. Exemplary replacement blocks 22 may be L-shaped, arc-shaped, or angled.

[0118] See also Figure 1 and Figure 2 In some embodiments, the outer frame 10 is provided with a quick mounting seat 60 for connecting the fitness equipment, and the quick mounting seat 60 and the outer frame 10 are detachably mounted. In this embodiment, the quick mounting seat 60 is adapted to the fitness equipment, and the fitness equipment is provided with a quick connection structure corresponding to the quick connection seat. By adopting the fixing member 100 of the present application, when installing the fitness equipment, it is no longer necessary to fix the fitness equipment on the rack. It is only necessary to quickly install the fixing member 100 on the rack and then quickly connect the fitness equipment to the fixing member 100. The specific quick connection structure can be any quick connection structure in the prior art, and this application will not repeat it.
