[0038] The embodiment of the present application provides a simple fixing part 100, which is mainly aimed at the installation and use of convenient and detachable fitness equipment. Since there is no unified industry standard for the rack used to fix fitness equipment in the current fitness equipment industry, each manufacturer has no fixed standard for the length and width of the rack cross section and the hole diameter and hole spacing of the fixing holes on the rack, which may cause the fitness equipment to be unable to be installed on the rack for use. Therefore, the present application provides a simple fixing part 100 that can adapt to racks of different sizes and models to facilitate the installation and use of fitness equipment.

[0039] See also Figure 1-Figure 3 A simple fixing part 100 of an embodiment of the present application includes a base plate 10, a screw rod 20, a nut 30 and a positioning pin 40. A mounting seat 11 is provided on the base plate 10 for mounting fitness equipment. A sliding groove 12 is provided on the base plate 10. The screw rod 20 is used to pass through the mounting hole. The nut 30 is threadedly connected to the screw rod 20, wherein one of the screw rod 20 and the nut 30 is fixed to the base plate 10. The positioning pin 40 is provided on the base plate 10 and slides in the sliding groove 12.

[0040] In the simple fixing part 100 of the embodiment of the present application, the substrate 10 provided with the mounting seat 11 can be fixed on the rack with different cross-sectional sizes by passing the screw 20 through the mounting hole on the rack and cooperating with the nut 30. The slidable positioning pin 40 can adapt to the rack with different hole spacing to improve the stability between the substrate 10 and the rack. Therefore, the fitness equipment can be stably installed on racks of different models through the simple fixing part 100, which has strong adaptability and is convenient to install and disassemble.

[0041] Specifically, the base plate 10 can be set as a plate-like structure, and the mounting seat 11 is fixed on a side surface of the base plate 10. The mounting seat 11 can be used to install fitness equipment. The mounting seat 11 can be set as a detachable structure relative to the base plate 10 to adapt to different fitness equipment.

[0042] The screw 20 and the nut 30 can be arranged on the side of the base plate 10 opposite to the mounting base 11. One of the screw 20 and the nut 30 is connected to the base plate 10, and the other is threadedly connected to the former so that the base plate 10 can be fixed on the rack. The adjustable connection method of the screw 20 and the nut 30 can make the simple fixing member 100 adaptable to racks with different cross-sectional sizes. The present application does not limit the specific connection method of the screw 20 and the nut 30 relative to the base plate 10, and the base plate 10 can be fixed on the rack by the nut 30 and the screw 20.

[0043] For example, when the screw rod 20 is fixed on the base plate 10, the screw rod 20 can be passed through the mounting hole on the frame, and the nut 30 can be threadedly connected to the screw rod 20 passing through the mounting hole, so that the base plate 10 can be fixed on the frame; when the nut 30 is fixed on the base plate 10, the nut 30 can be aligned with the mounting hole, and the screw rod 20 can be passed through the mounting hole and threadedly connected to the nut 30, so that the base plate 10 can be fixed on the frame. At this time, a bolt-like structure is provided at the end of the screw rod 20 away from the nut 30, which can be stuck outside the mounting hole.

[0044] Furthermore, since the substrate 10 and the frame are connected only by the nut 30 and the screw 20, the substrate 10 is prone to rotate relative to the frame, which will make it inconvenient to fix the fitness equipment, affecting the use of the fitness equipment. Therefore, another base point connected to the frame can be provided on the substrate 10 to ensure the stability of the substrate 10 relative to the frame. The embodiment of the present application can provide the fulcrum through the positioning pin 40, wherein the positioning pin 40 can be adjusted on the substrate 10, for example, a plurality of mounting holes are provided on the substrate 10, so that the positioning pin 40 can be installed at one of them, or a sliding groove 12 is provided on the substrate 10, so that the positioning pin 40 can be slidably set in the sliding groove 12.

[0045] The specific solution is to open a sliding groove 12 on the base plate 10. The sliding groove 12 can be in a strip shape and is set through the base plate 10. One end of the positioning pin 40 passes through the sliding groove 12 and can slide in the sliding groove 12. When fixing the base plate 10, after the screw 20 and the nut 30 are installed on the corresponding mounting hole, the positioning pin 40 can be slid to the corresponding mounting hole on the frame, so that the base plate 10 and the frame can be fixed at two points to avoid the rotation of the base plate 10. At the same time, since the positions of the screw 20 and the nut 30 relative to the base plate 10 are fixed, the positioning pin 40 that can slide relative to the base plate 10 can make the simple fixing part 100 adapt to the frame with different mounting hole spacings.

[0046] See also Figure 2-Figure 4In some embodiments, the screw rod 20 is fixedly connected to the substrate 10. The nut 30 includes: a rotating seat 31, a half nut 32, an elastic member 33 and an unlocking device 34. The rotating seat 31 is provided with a through hole 311 for inserting the screw rod 20. The half nut 32 is movably arranged on the rotating seat 31, and is partially located in the through hole 311, and is used to engage with the screw rod 20. The elastic member 33 is used to apply elastic force to move the half nut 32 toward the center of the through hole 311. The unlocking device 34 is used to work in conjunction with the half nut 32 to move the half nut 32 away from the center of the through hole 311.

[0047] In this way, when the screw 20 extends out of the mounting hole for a long time, the nut 30 can separate the half nut 32 and the screw 20 through the unlocking device 34, so that the nut 30 and the screw 20 can be disengaged without rotating more circles, thereby facilitating the disassembly of the simple fixing part 100.

[0048] Specifically, a mounting cavity 312 may be provided inside the rotating seat 31, and a through hole 311 is provided in the middle, and the diameter of the through hole 311 may be adapted to the diameter of the screw 20. The unlocking device 34 is at least partially movably disposed in the mounting cavity 312, and the other end thereof at least partially extends out of the mounting cavity 312, so as to facilitate pressing or pulling when unlocking. The half nut 32 is movably disposed in the mounting cavity 312 and can be linked with the unlocking device 34; the elastic member 33 may be a spring, one end of which may be connected to the inner wall of the mounting cavity 312, and the other end may be connected to the unlocking device 34 or the half nut 32, so as to provide the half nut 32 with elastic force to move toward the center of the through hole 311, so that the half nut 32 can be threadedly matched with the screw 20.

[0049] Furthermore, the half nut 32 can also be integrated with the unlocking device 34, that is, a half-threaded hole is opened at the corresponding position of the unlocking device 34 and the through hole 311, and the elastic member 33 is connected to the unlocking device 34 to provide elastic force. The present application does not limit the specific installation and connection method of the unlocking device 34, the half nut 32 and the elastic member 33, as long as the half nut 32 has an elastic force to move toward the center of the through hole 311.

[0050] See also Figure 5 In some embodiments, the angle between the end face of the screw 20 thread away from the mounting seat 11 and / or the end face of the nut 30 thread (not shown in the figure) close to the mounting seat 11 and the cross-section of the screw 20 is smaller than the friction angle.

[0051] In this way, the nut 30 and the screw rod 20 can have greater friction when they are threadedly connected, avoiding the risk of the nut 30 and the screw rod 20 loosening or even the nut 30 falling off when the fitness equipment is shaken, thereby improving the stability of the simple fixing member 100 when in use.

[0052] Specifically, the tightness and firmness of the connection between the screw 20 and the nut 30 is determined by the friction force of the fit of the threads of the two. The component force of the axial force generated between the screw 20 and the nut 30 on the end face of the thread will push the nut 30 away from the screw 20 in the radial direction. When the angle between the end face of the screw 20 thread away from the mounting seat 11 and / or the end face of the nut 30 thread close to the mounting seat 11 and the cross-section of the screw 20 is less than the friction angle, the component force of the axial force pushing the nut 30 away from the screw 20 in the radial direction will be less than the friction force generated by the axial force acting on the end face of the thread, thereby achieving a self-locking effect, so that the pulling force of the screw 20 cannot act on the elastic member 33 through the thread, avoiding the situation where the pulling force forcibly pulls the half nut apart, and improving the connection stability between the screw 20 and the nut 30.

[0053] In some embodiments, the angle between the end face of the screw 20 thread away from the mounting seat 11 and / or the end face of the nut 30 thread close to the mounting seat 11 and the cross section of the screw 20 is zero, which directly eliminates the radial component of the axial force of the screw 20. In this way, the connection stability between the screw 20 and the nut 30 is better.

[0054] It is understandable that when the screw 20 or the nut 30 is cut along the axial direction, the thread end face close to the mounting seat 11 is perpendicular to the axis of the screw 20, thereby maximizing the connection stability without hindering the threaded connection between the two, thereby preventing the nut 30 from detaching from the screw 20.

[0055] See also Figure 6 and Figure 7 In some embodiments, the positioning pin 40 includes a pin rod 41 and a pin sleeve 42, and the pin sleeve 42 is provided with a through hole or a blind hole, and the pin sleeve 42 is detachably sleeved on the pin rod 41. In this way, the pin sleeve 42 is detachable relative to the pin rod 41, so that the positioning pin 40 can be adapted to racks with different apertures by replacing the pin sleeve 42 with different diameters, thereby improving the adaptability of the simple fixing member 100. Of course, racks with different apertures can also be adapted by replacing the pin rod 41 with different diameters.

[0056] In some embodiments, the simple fixing part 100 can be equipped with multiple pin sleeves 42 with different outer diameters; it can also be equipped with multiple pin rods 41 with different outer diameters; it can also be equipped with pin rods 41 and pin sleeves 42 with different outer diameters.

[0057] That is to say, the outer diameters of the pin rod 41 and the pin sleeve 42 can be changed according to the diameters of the mounting holes of different racks, so that the simple fixing member 100 can be installed more stably and better adapted.

[0058] In some embodiments, the pin rod 41 and the pin sleeve 42 are threadedly connected, and a positioning shoulder 411 is provided on the pin rod 41. In this way, the pin rod 41 can slide in the sliding groove 12 through the positioning shoulder 411 to prevent the pin rod 41 from being separated from the sliding groove 12.

[0059] See also Figure 6 and Figure 7 In some embodiments, a through hole or blind hole of the pin sleeve 42 is provided with an anti-loosening sleeve 43 at the bottom of the hole away from the pin rod 41. The anti-loosening sleeve 43 has an internal thread engaged with the pin rod 41, and the anti-loosening sleeve 43 and the pin sleeve 42 are made of different materials.

[0060] In this way, the pin rod 41 can increase the friction between itself and the pin sleeve 42 by squeezing the anti-loosening sleeve 43 . The provision of the anti-loosening sleeve 43 can prevent the pin rod 41 and the pin sleeve 42 from loosening.

[0061] Specifically, the pin rod 41 and the pin sleeve 42 can be made of hard materials such as metal, and the anti-loosening sleeve 43 can be made of relatively flexible materials such as plastic and rubber. When the pin rod 41 is screwed into the internal thread of the anti-loosening sleeve 43, the anti-loosening sleeve 43 is located between the pin rod 41 and the pin sleeve 42, and the pin rod 41 will squeeze the anti-loosening sleeve 43 to increase the friction between the pin rod 41 and the pin sleeve 42 to prevent the two from loosening.

[0062] See also Figure 7 In some embodiments, the pin sleeve 42 is provided with a through hole, and an installation space 421 is provided at one end of the through hole away from the pin rod 41. A positioning groove 422 is provided on the inner wall of the installation space 421 along the circumferential direction, and a positioning edge 431 is provided on the outer wall of the anti-loosening sleeve 43 along the circumferential direction to cooperate with the positioning groove 422. In this way, the cooperation between the positioning edge 431 and the positioning groove 422 can prevent the anti-loosening sleeve 43 from being pushed out of the through hole 311 when the pin rod 41 is screwed in, so that the loosening sleeve and the pin rod 41 can cooperate better.
