[0030] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0031] When adjusting the extension arm of existing fitness equipment, due to processing errors and wear at the connection, the extension arm may not be adjusted properly, and the adjusted extension arm may be loose. When in use, the extension arm may make abnormal noises and shake, resulting in safety hazards and increased wear at the connection of the extension arm.

[0032] In view of this, some embodiments of the present specification provide a fitness equipment, which may include an adjustable accessory. The adjustable accessory can adjust the position of the extension arm in many aspects by setting a sliding component, a first component, and a second component. For example, the height position and angle position of the extension arm can be adjusted. The flexibility of the extension arm can be improved, and it is convenient for the user to adjust the extension arm according to different fitness movements.

[0033] In some embodiments, the fitness equipment may include removable accessories.

[0034] In some embodiments, at least a portion of the detachable accessory can be connected to at least a portion of the adjustable accessory. In some embodiments, the detachable accessory can be connected to the extension arm of the adjustable accessory through a rope body. In some embodiments, the fitness equipment can include multiple extension arms. For example, two, three or more. In some embodiments, each of the multiple extension arms can be connected to one or more detachable accessories respectively.

[0035] For more information about adjustable accessories, see Figure 1-Figure 11For more information about detachable accessories, see Figure 12-14 Related description.

[0036] Figure 1 It is a schematic diagram of the partial structure of the adjustable accessories shown in some embodiments of this specification.

[0037] Figure 2 yes Figure 1 Top view of the . Figure 3 yes Figure 1 Bottom view of .

[0038] In some embodiments, Figure 1-3 As shown, an adjustable accessory 100 for fitness equipment includes a column 110 , an extension arm 120 , a sliding assembly 130 , a first assembly 140 and a second assembly 150 .

[0039] The column 110 can be used as a mounting base for mounting the sliding assembly 130. In some embodiments, the column 110 can be made of a profile. A profile refers to a material with a certain cross-section shape. For example, a steel profile. By using a profile, the strength of the column 110 can be increased. In some embodiments, the length direction of the column 110 can be along the vertical direction (for example, Figure 1 ) settings in the Z direction.

[0040] The extension arm 120 refers to a structure that can be used to provide support for at least part of the weight of the fitness equipment. For example, the fitness equipment may include at least one weight block and at least one rope for pulling the weight block. The rope can be arranged on the extension arm 120, and the user can drive at least one weight block to move by pulling the rope, thereby achieving the effect of exercise. The extension arm 120 can be used to change the direction of at least part of the rope so that the user can avoid at least one weight block to avoid the weight block from colliding with the user when moving. In some embodiments, the rope can be arranged inside the extension arm 120. In some embodiments, a fixed pulley to which the rope is rollingly connected can be arranged inside the extension arm 120 to reduce the wear of the rope.

[0041] In some embodiments, the extension arm 120 can be made of metal materials, such as steel. In some embodiments, the extension arm 120 can be made of profiles, such as steel profiles, etc. This can improve the strength of the extension arm 120 and ensure safety during use.

[0042] In some embodiments, the extension arm 120 may be located on at least one side of the column 110 , thereby forming an exercise space for exercise between the extension arm 120 and the column 110 .

[0043] In some embodiments, the column 110 can be used to guide the movement of the weight block and / or limit the moving direction of the weight block to improve safety. In some embodiments, a weight groove can be provided on the column 110, and the weight block can be slidably connected to the weight groove.

[0044] The sliding assembly 130 refers to a structure that can move relative to other structures, for example, relative to the column 110 .

[0045] In some embodiments, the sliding assembly 130 is slidably disposed on the column 110. In some embodiments, the sliding assembly 130 can be slidably disposed on the column 110 along a vertical direction (eg, Figure 1 The Z direction in the image.

[0046] In some embodiments, the sliding assembly 130 may be connected to at least one side of the column 110. In some embodiments, a sliding connection and / or a rolling connection may be formed between the sliding assembly 130 and the column 110.

[0047] In some embodiments, the column 110 can limit the rotational freedom of the sliding assembly 130 in a variety of ways. For example, the column 110 can be slidably engaged with the sliding assembly 130. By limiting the rotational freedom of the sliding assembly 130, the stability of the sliding assembly 130 can be improved. When the sliding assembly 130 slides relative to the column 110, problems such as looseness and shaking can be avoided.

[0048] In some embodiments, the sliding assembly 130 and the column 110 may be relatively fixed. For example, when the sliding assembly 130 moves to a first relative position relative to the column 110, the sliding assembly 130 may be relatively fixed to the column 110. The first relative position may include at least one position on the column 110 along the vertical direction.

[0049] The first component 140 can be used as a mounting base for mounting at least a portion of the structure of the second component 150. In some embodiments, the first component 140 is rotatably mounted on the sliding component 130. When the sliding component 130 slides on the column 110, it can drive the first component 140 to move together; when the first component 140 rotates, it can drive the second component 150 to rotate synchronously.

[0050] In some embodiments, the center of rotation of the first component 140 can be parallel to the vertical direction (eg, Figure 1 in the Z direction).

[0051] In some embodiments, the first component 140 may be rotatably connected to the sliding component 130 in a variety of ways. For example, the first component 140 may include at least one rotating shaft, which is rotatably connected to the sliding component 130. In some embodiments, a bearing may be provided between the first component 140 and the sliding component 130, and the bearing is used to reduce the friction between the first component 140 and the sliding component 130, thereby reducing the wear of the first component 140 and the sliding component 130.

[0052] In some embodiments, the first component 140 and the sliding component 130 may be relatively fixed. For example, when the first component 140 rotates to a second relative position relative to the sliding component 130, the first component 140 may be relatively fixed to the sliding component 130. The second relative position may include at least one position in the circumferential direction of the rotation center of the first component 140.

[0053] The second assembly 150 can serve as a mounting base for mounting the extension arm 120 .

[0054] In some embodiments, the second component 150 is connected to the first component 140. When the sliding component 130 slides on the column 110, it can drive the first component 140, the second component 150 and the extension arm 120 to move together; when the first component 140 rotates, the first component 140 can drive the second component 150 and the extension arm 120 to rotate synchronously, thereby adjusting the position of the extension arm 120. For example, the position of the extension arm 120 in the horizontal plane is adjusted. The horizontal plane refers to a plane perpendicular to the vertical direction (for example, Figure 1 The plane is the Z direction in the image.

[0055] In some embodiments, the extension arm 120 is rotatably connected to the second component 150. The extension arm 120 can rotate relative to the second component 150 to further adjust the position of the extension arm 120. In some embodiments, the rotation center of the extension arm 120 relative to the second component 150 can be perpendicular to the vertical direction (for example, Figure 1 The Z direction in the drawing) can be used to adjust the angle of the length direction (i.e., the extension direction) of the extension arm 120 relative to the vertical direction.

[0056] In some embodiments, the extension arm 120 and the second component 150 may be relatively fixed. For example, when the extension arm 120 rotates to a third relative position relative to the second component 150, the extension arm 120 may be relatively fixed to the second component 150. The third relative position may include at least one position in the circumferential direction of the rotation center of the extension arm 120.

[0057] The adjustable accessories provided in some embodiments of the present specification can be used to adjust multiple degrees of freedom of the extension arm, thereby improving the flexibility of the extension arm, changing the position of the extension arm according to user needs, and expanding the scope of application of the fitness equipment.

[0058] Figure 4 It is a schematic diagram of the partial structure of the column shown in some embodiments of this specification. Figure 5 It is another partial structural schematic diagram of a column shown in some embodiments of this specification. Figure 6 It is a schematic diagram of the structure of a slider shown in some embodiments of this specification. Figure 7 It is a schematic diagram of the connection between the sliding assembly and the column shown in some embodiments of this specification.

[0059] In some embodiments, Figure 7 As shown, the sliding assembly 130 may include a slider 131 and a slider latch 132 .

[0060] The slider 131 refers to a structure that can slide relative to other structures. In some embodiments, the slider 131 is slidably connected to the column 110.

[0061] In some embodiments, Figure 5 As shown, at least one slider limiting hole 115 is provided on the column 110 .

[0062] The slider latch 132 refers to a structure that can be connected to a hole. For example, it can be connected to the slider stop hole 115. In some embodiments, the slider latch 132 is disposed on the slider 131 and can cooperate with at least one slider stop hole 115 so that the slider 131 and the column 110 can be relatively fixed, thereby controlling the sliding assembly 130 and the column 110 to be in different first relative positions. When the slider latch 132 is separated from the slider stop hole 115, the slider 131 can slide relative to the column 110.

[0063] In some embodiments, the plurality of slider limiting holes 115 may be arranged along a vertical direction (eg, Figure 1 The Z direction) is arranged on the column 110.

[0064] In some embodiments, at least a portion of the slider pin 132 may pass through the slider 131 and cooperate with the slider stop hole 115. In some embodiments, a portion of the slider pin 132 may be connected to the slider 131 in a variety of ways, such as at least one of a snap connection, a threaded connection, and a welding connection.

[0065] In some embodiments, Figure 4 As shown, a column sliding groove 111 is provided on at least one side surface of the column 110 .

[0066] The column slot 111 includes a groove structure that is concave relative to the side of the column 110. In some embodiments, the column slot 111 can be along the length direction of the column 110 (for example, Figure 1 In some embodiments, the slider 131 is slidably disposed in the column slot 111. The column slot 111 can limit and guide the slider 131 to a certain extent, which is beneficial to improving the stability and movement accuracy of the slider 131. In some embodiments, at least part of the cross-sectional shape of the column slot 111 can be matched with at least part of the cross-sectional shape of the slider 131, so that the slider 131 can be installed in conjunction with the column slot 111, which is beneficial to further improve the stability of the slider 131 and the column slot 111.

[0067] In some embodiments, Figure 4 As shown, a U-shaped guide rail 112 is provided in the column slide groove 111 .

[0068] The U-shaped guide rail 112 refers to a structure protruding from the inner side of the column slide groove 111. In some embodiments, the cross section of the U-shaped guide rail 112 is U-shaped. In some embodiments, the U-shaped guide rail 112 can be extended along the length direction of the column 110 (for example, Figure 1 ) settings in the Z direction.

[0069] In some embodiments, Figure 6 As shown, the slider 131 is provided with a U-shaped slide groove 1311 adapted to the U-shaped guide rail 112, and the slider 131 can slide along the U-shaped guide rail 112. The cooperation between the U-shaped guide rail 112 and the U-shaped slide groove 1311 can further restrict the slider 131, limit the moving direction and rotational freedom of the slider 131, and help improve the stability of the slider 131 when moving.

[0070] In some embodiments, a plurality of slider limiting holes 115 may be provided on the U-shaped guide rail 112. Figure 5 As shown, a steel sheet 114 is provided on the U-shaped guide rail 112. The steel sheet 114 can be provided along the length direction of the column 110 (for example, Figure 1 In some embodiments, the steel sheet 114 is slidably connected to the slider 131. By providing the steel sheet 114, the friction force when the slider 131 moves can be reduced. In some embodiments, the steel sheet 114 can be provided on the U-shaped guide rail 112 in a variety of ways. For example, at least one of clamping, bonding, welding, etc.

[0071] In some embodiments, Figure 4 As shown, at least one side of the U-shaped guide rail 112 is provided with a guide rail groove 113. For example, one guide rail groove 113 is respectively provided on two opposite sides of the U-shaped guide rail 112.

[0072] The guide rail groove 113 refers to a structure that is concave relative to the outer surface of the U-shaped guide rail 112. In some embodiments, the guide rail groove 113 can be along the length direction of the column 110 (for example, Figure 1 ) settings in the Z direction.

[0073] In some embodiments, Figure 6 As shown, the slider 131 is provided with a slider protrusion 1312 adapted to the guide rail groove 113. In some embodiments, the slider protrusion 1312 can be engaged with the guide rail groove 113, so that the slider 131 is clamped on the U-shaped guide rail 112 to prevent the slider 131 from being separated from the U-shaped guide rail 112.

[0074] In some embodiments, a rounded transition may be used at the corner between the slider protrusion 1312 and the guide rail groove 113 , which helps to reduce the wear between the slider protrusion 1312 and the guide rail groove 113 .

[0075] In some embodiments, the cross-sectional shape of the guide rail groove 113 may include multiple shapes. For example, at least one of a rounded triangle, an arc, etc. In some embodiments, the cross-sectional shape of the slider protrusion 1312 may be adapted to the cross-sectional shape of the guide rail groove 113. This reduces the gap between the slider protrusion 1312 and the guide rail groove 113, which helps prevent the slider 131 from loosening relative to the U-shaped guide rail 112.

[0076] In some embodiments, Figure 6 As shown, a plurality of rollers 1314 are provided on the slider 131 .

[0077] In some embodiments, the roller 1314 is rotatably connected to the slider 131. In some embodiments, multiple rollers 1314 can be rollingly connected to the column 110. In some embodiments, the U-shaped slide groove 1311 on the slider 131 contacts the U-shaped guide rail 112, and a gap is formed between the other outer surface of the slider 131 and the column 110. Multiple rollers 1314 are rollingly connected to one of the side surfaces of the column slide groove 111. In this way, the contact area between the slider 131 and the column 110 is reduced, thereby reducing the friction force when the slider 131 moves. The roller 1314 can support the slider 131 and improve the stability of the slider 131. Since the roller 1314 is rollingly connected to the side of the column slide groove 111, the friction force when the roller 1314 moves can also be reduced.

[0078] In some embodiments, Figure 7 As shown, the slider latch 132 includes a first latch 1321, a first spring 1322, a first handle 1323, a first limit block 1324 and a first connection block 1325. Figure 6 As shown, a slider locking hole 1313 is provided on the slider 131 .

[0079] The slider locking hole 1313 refers to a through hole for passing the slider latch 132 .

[0080] The first stopper 1324 can be disposed in the slider lock hole 1313 in a variety of ways, such as at least one of a clamping connection, a threaded connection, and a welding connection. In some embodiments, the first stopper 1324 can be a cylindrical structure.

[0081] The first latch 1321 is a latch that can be installed in cooperation with the slider limiting hole 115. In some embodiments, the first latch 1321 can pass through the slider locking hole 1313 and the first limiting block 1324, and be engaged with the slider limiting hole 115.

[0082] In some embodiments, the first latch 1321 is connected to a first connection block 1325 at one end close to the slider limiting hole 115 . The first latch 1321 can drive the first connection block 1325 to move synchronously, and the first connection block 1325 can be engaged with the slider limiting hole 115 .

[0083] In some embodiments, the first spring 1322 is sleeved on the first latch 1321. One end of the first spring 1322 is connected to the first limit block 1324, and the other end of the first spring 1322 is connected to the first connection block 1325. In some embodiments, the first spring 1322 can be in a compressed state and compressed between the first limit block 1324 and the first connection block 1325. In this way, in the absence of external force, the first spring 1322 can apply pressure to the first connection block 1325 to limit the first connection block 1325 in the slider limit hole 115, so that the slider 131 is in a locked state. It is helpful to prevent the first latch 1321 from being separated from the slider limit hole 115 to avoid potential safety hazards. By applying a pulling force to the first latch 1321 to overcome the spring force of the first spring 1322, the first connection block 1325 can be pulled out of the slider limit hole 115, so that the slider 131 is in a movable state.

[0084] The first connection block 1325 can form a structure protruding relative to the outer surface of the first latch 1321, and serve as a mounting base for the first spring 1322. In some embodiments, the first connection block 1325 and the first latch 1321 can be connected in a variety of ways, such as at least one of clamping, welding, threaded connection, and integral molding.

[0085] In some embodiments, the first latch 1321 can be threadedly connected to the first limit block 1324. By rotating the first latch 1321, the first latch 1321 is screwed in or out relative to the first limit block 1324, so as to control the connection or separation of the first connection block 1325 and the slider limit hole 115, which can prevent the first connection block 1325 from accidentally loosening from the slider limit hole 115 and avoid potential safety hazards.

[0086] In some embodiments, the first handle 1323 is connected to an end of the first latch 1321 away from the slider limiting hole 115. The first handle 1323 can be used to easily apply force to the first latch 1321. In some embodiments, the first handle 1323 and the first latch 1321 can be connected in a variety of ways, such as at least one of clamping, welding, threaded connection, and integral molding.

[0087] The sliding assembly provided in some embodiments of the present specification can drive the extension arm to move in the vertical direction as a whole, thereby adjusting the height of the extension arm to adapt to users of different heights, or to assist different fitness movements, thereby expanding the scope of application of fitness equipment. The sliding assembly can be locked or released by the slider latch, and the sliding assembly can be locked or adjusted quickly and conveniently, which has the advantage of being easy to use. By using multiple slider limit holes, the position of the extension arm when moving can be limited, thereby improving the control accuracy of the extension arm when moving in the vertical direction.

[0089] In some embodiments, Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, the first component 140 includes an adjustment column 141 , an adjustment base 143 and a disc latch 144 . The adjustment base 143 is disposed on the sliding component 130 .

[0090] The adjustment base 143 can serve as an installation base for installing the adjustment column 141 .

[0091] In some embodiments, the sliding assembly 130 is moved in a vertical direction (eg, Figure 1 When the adjusting base 143 moves (in the Z direction), the adjusting base 143 can be driven to move synchronously.

[0092] In some embodiments, the adjustment base 143 is disposed on the slider 131. In some embodiments, the adjustment base 143 can be connected to the slider 131 in a variety of ways, such as at least one of a snap connection, a threaded connection, welding, and an integral molding.

[0093] In some embodiments, the upper surface of the adjustment base 143 is perpendicular to the vertical direction (eg, Figure 1 in the Z direction).

[0094] The adjusting column 141 refers to a columnar structure arranged on the adjusting base 143. In some embodiments, the adjusting column 141 is rotatably arranged on the adjusting base 143. In some embodiments, the adjusting column 141 can be used as a mounting base for mounting a partial structure of the second component 150. When the adjusting column 141 rotates, the second component 150 can be driven to rotate synchronously. In some embodiments, the adjusting column 141 can be a rotating body-shaped structure. In some embodiments, the adjusting column 141 can include a rotating shaft rotatably connected to the adjusting base 143. In some embodiments, a bearing can be arranged between the rotating shaft and the adjusting base 143 to reduce the wear between the rotating shaft and the adjusting base 143.

[0095] In some embodiments, Fig. 9 As shown, at least part of the side surface of the adjustment base 143 includes a first cylindrical surface 1431 .

In some embodiments, the adjustment limit holes 1432 may be distributed along the circumference of the first cylindrical surface 1431. In some embodiments, the axis of the adjustment limit hole 1432 may be collinear with the radial direction of the first cylindrical surface 1431.

[0097] In some embodiments, Figure 8 As shown, an adjusting locking block 142 is disposed on the adjusting column 141 , and a disc locking hole 1421 is disposed on the adjusting locking block 142 . The disc locking hole 1421 can be aligned with the adjusting limiting hole 1432 .

[0098] The adjustment lock block 142 can serve as a mounting base for mounting the disc latch 144. In some embodiments, the adjustment lock block 142 is disposed at one end of the adjustment column 141 close to the adjustment base 143, and can protrude outward relative to the outer surface of the adjustment column 141. When the adjustment column 141 rotates, the adjustment lock block 142 can be driven to move synchronously, so that the disc lock hole 1421 is aligned with different adjustment limit holes 1432.

[0099] In some embodiments, the adjusting lock block 142 and the adjusting column 141 may be connected in a variety of ways, such as at least one of clamping, welding, threaded connection, and integral molding.

[0100] The disc latch 144 refers to a structure that can be connected to a hole. For example, it is connected to the disc lock hole 1421 and the adjustment limit hole 1432. In some embodiments, the disc latch 144 can detachably pass through the disc lock hole 1421 and the adjustment limit hole 1432. When the disc latch 144 passes through the disc lock hole 1421 and the adjustment limit hole 1432, the adjustment column 141 is kept fixed relative to the adjustment base 143, and the adjustment column 141 can no longer rotate. When the disc latch 144 is separated from the adjustment limit hole 1432, the adjustment column 141 and the adjustment base 143 can rotate relative to each other. By making the disc latch 144 cooperate with different adjustment limit holes 1432, the first component 140 and the sliding component 130 can be in different second relative positions.

[0101] By using the disc latch, the first component and the sliding component can be quickly connected or separated, thereby facilitating quick adjustment of the fitness equipment.

[0102] In some embodiments, Figure 3 As shown, the disc latch 144 includes a second latch 1441 , a second spring 1442 , a second handle 1443 , a second limiting block 1444 and a second connecting block 1445 .

[0103] One end of the second latch 1441 is connected to the second handle 1443 . The second limiting block 1444 and the second connecting block 1445 are respectively mounted on the second latch 1441 . The second limiting block 1444 can be connected to the adjusting lock block 142 .

[0104] The second spring 1442 is sleeved on the second latch 1441, one end of the second spring 1442 is connected to the second limit block 1444, and the other end of the second spring 1442 is connected to the second connection block 1445. In some embodiments, the second spring 1442 can be arranged in a compressed state between the second limit block 1444 and the second connection block 1445. In some embodiments, the second connection block 1445 can be detachably connected to the adjustment limit hole 1432.

[0105] In some embodiments, the disc latch 144 has a similar structure to the slider latch 132. For more information about the disc latch 144, see Figure 7 Related description about the slider latch 132.

[0106] In some embodiments, the first component 140 may be made of metal material to ensure the strength of the first component, for example, stainless steel.

[0107] The first component provided in some embodiments of the present specification can drive the extension arm to rotate as a whole in the horizontal plane, thereby adjusting the angle of the extension arm in the horizontal plane, and can be used to assist different fitness movements, thereby expanding the scope of application of fitness equipment. The first component can be locked or released by a disc latch, and can be locked or released quickly and easily, which has the advantage of being easy to use. By using multiple adjustment limit holes, the rotation angle of the extension arm can be limited, which is conducive to improving the control accuracy of the extension arm when it rotates in the horizontal plane.

[0108] Fig.10 It is a partial structural schematic diagram of the second component shown in some embodiments of this specification. Fig.11 It is a schematic diagram of the connection between the second component and the extension arm according to some embodiments of the present specification.

[0109] In some embodiments, Figure 1 , Fig.10 , Fig.11 As shown, the second assembly 150 includes an adjusting member 151, a connecting rod 152 and an operable operating member 153. The adjusting member 151 is disposed on the adjusting column 141. The extension arm 120 is rotatably connected to the adjusting member 151. One end of the connecting rod 152 is detachably connected to the adjusting member 151, and the other end of the connecting rod 152 is transmission-connected to the operating member 153.

[0110] The adjustment member 151 refers to a structure that can be used to adjust the position of the extension arm 120. For example, the adjustment member 151 can be used to adjust the angle between the extension arm 120 and the vertical direction.

[0111] In some embodiments, the adjusting member 151 can be connected to the adjusting column 141 in a variety of ways, such as at least one of a clamping connection, a threaded connection, a welding connection, and an integral molding connection. When the adjusting column 141 rotates, the adjusting column 141 can drive the adjusting member 151 to rotate synchronously, and the adjusting member 151 can drive the extension arm 120 to rotate synchronously.

[0112] In some embodiments, Figure 8 , Fig.10 As shown, the adjusting member 151 includes at least one disc gear 1510. At least one disc gear 1510 is disposed on the circumferential surface of the adjusting column 141. In some embodiments, the extension arm 120 may be rotatably connected to the disc gear 1510, and the rotation center of the extension arm 120 may be colinear with the axis of the disc gear 1510.

[0113] In some embodiments, the extension arm 120 can be rotatably connected to the disc gear 1510 in a variety of ways. For example, the extension arm shaft can be connected, and the extension arm shaft can simultaneously penetrate at least a portion of the extension arm 120 and the disc gear 1510. In some embodiments, the extension arm shaft can be fixed to the extension arm 120 and can be rotatably connected to the disc gear 1510. Alternatively, the extension arm shaft can be rotatably connected to the extension arm 120 and can be fixed to the disc gear 1510.

[0114] The disc gear 1510 refers to a disc-shaped structure with a toothed structure. In some embodiments, at least a portion of the outer surface of the disc gear 1510 may include a second cylindrical surface 1511. The second cylindrical surface 1511 is disposed on the circumference of the disc gear 1510. In some embodiments, the axis of the second cylindrical surface 1511 may be perpendicular to the axis of the adjustment column 141.

[0115] In some embodiments, a plurality of adjustment tooth grooves 1512 are disposed on the second cylindrical surface 1511 , and the plurality of adjustment tooth grooves 1512 may be disposed along the circumference of the second cylindrical surface 1511 .

[0116] The adjustment tooth groove 1512 can be used to form a connection relationship with the connecting rod 152.

[0117] In some embodiments, the connecting rod 152 can be detachably engaged with the adjustment tooth groove 1512. When the connecting rod 152 is engaged with the adjustment tooth groove 1512, the relative position of the extension arm 120 and the disc gear 1510 remains fixed. When the connecting rod 152 is separated from the adjustment tooth groove 1512, the extension arm 120 can rotate relative to the disc gear 1510. By engaging the connecting rod 152 with a plurality of adjustment tooth grooves 1512, the extension arm 120 and the second component 150 can be in a different third relative position.

[0118] For more information about the connecting rod 152 , please refer to the following description.

[0119] In some embodiments, two disc gears 1510 may be provided. In some embodiments, the two disc gears 1510 may be parallel to each other. In some embodiments, the two disc gears 1510 may be coaxial. In some embodiments, the adjustment tooth grooves 1512 on the two disc gears 1510 may be aligned with each other. The connecting rod 152 may be connected to the two disc gears 1510 at the same time.

[0120] By using two disc gears, the extension arm and the connecting rod can be supported from two directions, which can improve the stability of the extension arm and the connecting rod and enhance the carrying capacity of the adjustment member.

[0121] In some embodiments, the extension arm 120 may be rotatably connected to two disc gears 1510 , respectively.

[0122] In some embodiments, a receiving space may be provided at one end of the extension arm 120 close to the disc gear 1510, and the receiving space may be a groove-shaped structure. Two disc gears 1510 may be located in the receiving space, and two opposite sides of the receiving space may be rotatably connected to one disc gear 1510 respectively.

[0123] In some embodiments, the disc gear 1510 and the adjusting column 141 can be connected in a variety of ways, such as at least one of snap connection, threaded connection, welding, and integral molding.

[0124] By adopting the disc gear, the adjustment tooth groove on the disc gear can be used to form a division, so as to control different angles of the extension arm in the vertical plane, which is beneficial to improve the control accuracy when controlling the extension arm to rotate in the vertical plane.

[0125] The connecting rod 152 refers to a rod-shaped structure for connecting with the adjusting member 151. In some embodiments, the connecting rod 152 may be parallel to the extension arm 120. In some embodiments, the extension arm 120 may be a hollow structure, and the connecting rod 152 may be disposed inside the extension arm 120.

[0126] For more information about the connecting rod 152 , please refer to the above description.

[0127] The operating member 153 refers to a structure with an operating function. For example, the operating member 153 can move back and forth under the action of an external force. In some embodiments, the operating member 153 can drive the connecting rod 152 to move synchronously. In some embodiments, the operating member 153 can move back and forth along the length direction of the extension arm 120, thereby driving the connecting rod 152 to move back and forth along the length direction of the extension arm 120. When the operating member 153 drives the connecting rod 152 to move to the first position in a direction away from the adjustment member 151, the connecting rod 152 can be separated from the adjustment member 151, so that the degree of freedom of the extension arm 120 to rotate around the extension arm rotation axis is unlocked, and the extension arm 120 can rotate relative to the adjustment member 151. When the operating member 153 drives the connecting rod 152 to move to the second position in a direction close to the adjustment member 151, the connecting rod 152 can be engaged with the adjustment member 151, so that the degree of freedom of the extension arm 120 to rotate around the extension arm rotation axis is locked, and the extension arm 120 is fixed relative to the adjustment member 151, thereby locking the extension arm 120. The distance between the first position and the adjusting member 151 is greater than the distance between the second position and the adjusting member 151 .

[0128] In some embodiments, the operating member 153 may include an operating slot 1531, an operating block 1532, and a connecting sleeve 1533. The operating slot 1531 is provided on the extension arm 120. The operating block 1532 is slidably connected to the operating slot 1531.

The connecting sleeve 1533 is provided on the operating block 1532, and the connecting sleeve 1533 is connected to the connecting rod 152.

[0129] The operating slot 1531 can be used as a mounting base for mounting the operating block 1532. In some embodiments, the operating slot 1531 can be connected to the extension arm 120 in a variety of ways, such as at least one of snap-on, welding, and integral molding.

[0130] The operation block 1532 refers to a slider that can slide in the operation slot 1531. In some embodiments, the operation block 1532 can be slidably engaged with the operation slot 1531 to prevent the operation block 1532 from being separated from the operation slot 1531. In some embodiments, a gap can be formed between the operation slot 1531 and the extension arm 120, and the operation block 1532 can be engaged in the gap to further prevent the operation block 1532 from being separated from the operation slot 1531.

[0131] The connecting sleeve 1533 can be connected to the connecting rod 152, so as to transmit a pulling force or a pushing force to the connecting rod 152, thereby driving the connecting rod 152 to move. In some embodiments, the connecting sleeve 1533 and the connecting rod 152 can be connected in a variety of ways, such as at least one of a clamping connection and a threaded connection.

[0132] In some embodiments, two connection sleeves 1533 may be provided, and two connection rods 152 may be provided. Two connection sleeves 1533 may be connected to two connection rods 152 accordingly. This is beneficial to improve the stability of the extension arm 120, reduce the pressure transmitted from the extension arm 120 to the connection rod 152, and ensure the safety of the use of the connection rod 152.

[0133] In some embodiments, an adjusting pin 154 is connected to one end of the connecting rod 152 close to the adjusting member 151 .

[0134] The adjustment latch 154 can be detachably connected to the adjustment tooth groove 1512. In some embodiments, at least one side of the adjustment latch 154 is matched with the inner side of the adjustment tooth groove 1512. For example, the side of the adjustment latch 154 that contacts the adjustment tooth groove 1512 is matched with the inner side of the adjustment tooth groove 1512. This is conducive to making the adjustment latch 154 fully contact with the inner side of the adjustment tooth groove 1512, avoiding the problem of a gap forming and causing the extension arm 120 to shake.

[0135] In some embodiments, when two connecting rods 152 are provided, the two connecting rods 152 can be connected to the same disc latch 154 .

[0136] By connecting the ends of the two connecting rods 152 with the same disk latch 154, the stability and strength of the ends of the connecting rods 152 can be improved, and the two connecting rods 152 can be easily aligned with the adjustment tooth grooves 1512 at the same time, so as to avoid the ends of the two connecting rods 152 being misaligned and affecting the use.

[0137] In some embodiments, Fig.10 As shown, the disc latch 154 may include two latch plates 1541 and two latch screws 1542 .

[0138] The two connecting rods 152 can be respectively arranged between the two latch plates 1541 , and the latch screws 1542 can provide clamping force for the two latch plates 1541 so that the two latch plates 1541 clamp the two connecting rods 152 .

[0139] In some embodiments, Fig.11 As shown, a fixed pulley 155 can be provided on the latch plate 1541. The fixed pulley 155 can be used to change the moving direction of the rope body.

[0140] The disc latch provided in some embodiments of the present specification has the advantages of simple structure, convenient use and reliable clamping.

[0141] In some embodiments, a restoring structure is provided on the extension arm 120 .

[0142] The reset structure can apply a force to the operating member 153. When an external force is used to control the movement of the operating member 153, it is necessary to overcome the force applied by the reset structure to the operating member 153. After the external force is removed, the force applied by the reset structure to the operating member 153 can reset the operating member 153. In some embodiments, the reset structure can be configured to move the operating block 1532 from a first position to a second position. In this way, after the extension arm 120 is adjusted to a position, the force applied to the operating block 1532 is removed, and the reset structure can move the operating block 1532 from the first position to the second position, driving the connecting rod 152 to connect with the adjustment tooth groove 1512 to lock the extension arm 120. This makes adjustment more convenient.

[0143] In some embodiments, the return structure includes a return spring.

[0144] In some embodiments, one end of the return spring is connected to the extension arm 120, and the other end of the return spring is connected to the operating block 1532. When the operating member 1532 is in the first position, the return spring is in a first compressed state. When the operating member 1532 is in the second position, the return spring is in a second compressed state or a natural state. In some embodiments, the spring force in the second compressed state is less than the spring force in the first compressed state.

[0145] The use of a return spring has the advantages of simple structure and easy installation and use.

[0146] The second component provided in some embodiments of the present specification can drive the extension arm to rotate in the vertical plane as a whole, thereby adjusting the angle of the extension arm in the vertical plane, which can be used to assist different fitness movements. In combination with the first component to adjust the angle of the extension arm in the horizontal plane as a whole, the applicable scope of the fitness equipment can be further expanded. By using the operating member, the connection and separation of the adjustment member and the connecting rod can be remotely controlled, which has the advantages of being easy and quick to use.

[0147] Existing fitness equipment can only be used to assist a single fitness action. When users use different fitness actions to exercise, they need to change the corresponding fitness equipment. Different fitness equipment also has different connection ends (such as handles, etc.) with users, resulting in many redundant accessories and high cost of using fitness equipment.

[0148] In view of this, some embodiments of the present specification provide a detachable accessory, by providing a detachably connected first connector and a second connector, the first connector is set on a variety of fitness equipment, and the second connector is set on the connection end of the fitness equipment. Users can use a unified connection end to connect with a variety of fitness equipment, thereby reducing the use of redundant accessories. In public places such as gyms, users use their own connection ends to connect with different fitness equipment, which can reduce indirect contact with strangers.

[0149] Fig.12 It is a schematic diagram of the structure of detachable accessories shown in some embodiments of this specification. Fig.13 It is a partial cross-sectional view of a detachable accessory shown in some embodiments of the present specification. Fig.14 It is a schematic exploded view of detachable accessories shown in some embodiments of the present specification.

[0150] like Fig.12 , 13 As shown, the detachable accessory 200 for fitness equipment includes a handle 210 and a connecting assembly 220 .

[0151] The handle 210 refers to the part that the user holds when in use. In some embodiments, at least part of the handle 210 may include a rotating body-shaped structure. For example, one end connected to the connecting component 220. Avoid forming sharp protrusions to avoid potential safety hazards. In some embodiments, the diameter of at least one end of the handle 210 is larger than the diameter of the middle of the handle. For example, the handle 210 is away from one end of the connecting component 220. When in use, it is helpful to prevent the handle 210 from detaching from the user. In some embodiments, the outer side of the handle 210 is provided with an anti-slip structure. For example, an anti-slip pattern, etc. When in use, it is helpful to prevent the occurrence of problems such as slipping and the handle detaching from the user.

[0152] The connecting component 220 refers to a structure used to connect other structures, for example, connecting the rope body 230 and the handle 210 so that when the user pulls the handle 210 , force can be transmitted to the rope body 230 .

[0153] In some embodiments, the connection assembly 220 may include a first connection member 221 and a second connection member 222.

[0154] The rope 230 can be used to connect with a weight. For example, it can be connected with an iron sheet, a spring, etc. The user can pull the rope 230 to resist the gravity or elastic force of the weight, thereby achieving the effect of exercise. Fig.11 As shown, one end of the rope body 230 can pass through the extension arm 120 and be connected to the fixed pulley 155, and then be connected to the load after the fixed pulley 155 changes the movement direction.

[0155] In some embodiments, the second connector 222 may be disposed in the handle 210. The first connector 221 and the second connector 222 may be detachably connected. In some embodiments, when the first connector 221 and the second connector 222 are connected, the rope 230 and the handle 210 may be connected. When the first connector 221 and the second connector 222 are separated, the rope 230 and the handle 210 may be disconnected.

[0156] In some embodiments, the first connector 221 includes a spherical structure.

[0157] In some embodiments, the first connector 221 adopts a spherical structure, which can avoid forming a sharp protrusion structure, which is conducive to avoiding safety hazards. In some embodiments, a storage space is provided in the first connector 221 for accommodating at least part of the rope body 230. The first connector 221 is provided with a hole through which the rope body 230 can pass, and the hole is connected to the storage space.

[0158] In some embodiments, the rope body 230 can be connected to the first connecting member 221 via a knot 231 .

[0159] The knot 231 can be formed by tying the rope body 230, which has the advantage of being simple and convenient to operate. The size of the knot 231 in the radial direction is larger than the size of the rope body 230, and the knot 231 may not pass through the hole through which the rope body 230 can pass. When it is necessary to separate the rope body 230 from the first connecting member 221, the rope body 230 can be separated from the first connecting member 221 by untying the knot 231, without using an additional redundant structure, which is conducive to simplifying the structure.

[0160] The detachable accessories provided in some embodiments of the present specification can detachably connect the handle to the rope body, so that a variety of different fitness equipment can be connected using a unified handle, thereby improving the versatility of a variety of fitness equipment.

[0161] In some embodiments, the first connecting member 221 includes a snap ring 2211 , and the second connecting member 222 includes a snap mechanism that is snap-connected with the snap ring 2211 .

[0162] The snap ring 2211 refers to an annular structure provided on the first connecting member 221. At least a portion of the buckle mechanism can extend into the snap ring 2211 and form a connection with the snap ring 2211, so that the first connecting member 221 and the second connecting member 222 are snapped together.

[0163] The buckle mechanism is connected with the clamping ring 2211, which has the advantages of simple structure and convenient use.

[0164] In some embodiments, Fig.14 As shown, a ball head groove 2212 is provided on the spherical structure.

[0165] The ball head groove 2212 refers to a groove structure provided on the spherical structure. In some embodiments, the ball head groove 2212 can penetrate the ball head along the radial direction of the spherical structure.

[0166] In some embodiments, the snap ring 2211 is disposed in the ball head groove 2212. By disposing the snap ring 2211 in the ball head groove 2212, it is avoided that the snap ring 2211 forms a protrusion on the outer surface of the spherical structure, thereby preventing the risk of collision damage.

[0167] In some embodiments, the snap ring 2211 can be disposed in the ball head groove 2212 in a variety of ways, such as at least one of snap connection, threaded connection, and integral molding.

[0168] In some embodiments, at least a portion of the ball head can extend into the second connecting member 222. For example, the ball head groove 2212 can extend into the second connecting member 222. The second connecting member 222 can be used to shield the ball head groove 2212, thereby preventing impurities, sweat, etc. from entering the ball head groove 2212 and causing wear and corrosion, thereby ensuring the service life of the ball head.

[0169] In some embodiments, the knot 231 can pass through the ball head groove 2212 and extend out of the first connecting member 221 , thereby facilitating untying the knot 231 .

[0170] In some embodiments, the snap mechanism includes a snap 2221 .

[0171] The buckle 2221 can be detachably connected to the snap ring 2211. For example, hooking, etc. When the buckle 2221 is hooked with the snap ring 2211, the first connecting member 221 is connected to the second connecting member 222. When the buckle 2221 is separated from the snap ring 2211, the first connecting member 221 is disconnected from the second connecting member 222.

[0172] In some embodiments, the buckle 2221 may be L-shaped. In some embodiments, at least part of the side surface of the buckle 2221 facing the first connecting member may be an inclined surface. The inclination angle of the inclined surface may be 30°-80°. The inclination angle of the inclined surface may also be 30°-60°. The inclination angle of the inclined surface may also be 40°-55°. The inclination angle of the inclined surface may also be 45°-50°. When the first connecting member 221 moves in a direction close to the second connecting member 222, the snap ring 2211 may abut against the inclined surface of the buckle 2221. During the continuous movement of the first connecting member 221, the snap ring 2211 may apply a thrust to the inclined surface of the buckle 2221, so that the buckle 2221 moves in a direction away from the snap ring 2211. The moving direction of the buckle 2221 may be perpendicular to the moving direction of the snap ring 2211. Until the snap ring 2211 is separated from the inclined surface of the buckle 2221, the force applied by the snap ring 2211 to the inclined surface of the buckle 2221 disappears. The buckle 2221 is reset, and the buckle 2221 can be connected to the snap ring 2211.

[0173] In the process of moving the snap ring 2211, the snap ring 2211 can be engaged with the buckle 2221, which is helpful to simplify the connection between the first connecting member and the second connecting member, and has the advantages of being easy and quick to use.

[0174] In some embodiments, the second connecting member 222 further includes a snap button 2222 and a pressing spring 2223 .

[0175] The snap button 2222 refers to a button that can be pressed. In some embodiments, the snap button 2222 is pressably arranged on the second connecting member 222. In some embodiments, the snap button 2222 can be transmission-connected to the buckle mechanism. For example, it is transmission-connected to the buckle 2221. In some embodiments, the direction in which the snap button 2222 can be pressed is parallel to the radial direction of the second connecting member 222. In some embodiments, at least a portion of the snap button 2222 can protrude from the outer surface of the second connecting member 222, so as to facilitate pressing it.

[0176] In some embodiments, the snap button 2222 includes a cap body 22221 and a cylinder 22222. The cap body 22221 is connected to one end of the cylinder 22222. The other end of the cylinder 22222 can be connected to the buckle 2221. In some embodiments, the cap body 22221 can be a disc-shaped structure. The diameter of the cap body 22221 can be greater than the diameter of the cylinder 22222. In some embodiments, at least a portion of the cap body 22221 can protrude from the outer surface of the second connecting member 222. An activity space in which the cap body 22221 can move can be set in the second connecting member 222. By pressing the cap body 22221, the cap body 22221 can drive the buckle 2221 to move through the cylinder 22222, so that the buckle 2221 avoids the moving path of the snap ring 2211, so that the snap ring 2211 can enter or leave the second connecting member 222. When the first connecting member 221 and the second connecting member 222 need to be connected, the first connecting member 221 and the second connecting member 222 may be directly connected without pressing the buckle 2222 , so that the snap ring 2211 pushes the buckle 2221 .

[0177] In some embodiments, the cap body 22221 and the column body 22222 can be connected in a variety of ways, such as at least one of snap connection, threaded connection, and integral molding.

[0178] In some embodiments, the pressing spring 2223 is sleeved on the column 22222 , and the pressing spring 2223 abuts against the cap body 22221 and the second connecting member 222 , respectively.

[0179] The cap body 22221 can provide support for the pressing spring 2223. When the user presses the cap body 22221, the pressing spring 2223 can be compressed by the cap body 2222. When the user cancels the force on the cap body 22221, the cap body 22221 can be reset under the force of the pressing spring 2223, and the button 2222 can be reset.

[0180] By using the snap button, the user can apply force from the outside of the second connecting member to the buckle inside the second connecting member, thereby conveniently connecting or disconnecting the first connecting member with the second connecting member. The snap button can be automatically reset by using a spring, and when the first connecting member is connected to the second connecting member, a locking force is provided to lock the buckle with the clasp, thereby ensuring safety in use.

[0181] In some embodiments, a stepped hole is provided on the buckle 2221. In some embodiments, the large hole portion of the stepped hole can be connected to the column 22222. For example, by snap connection.

[0182] In some embodiments, an internal thread is provided at one end of the column 22222 near the buckle 2221. The second connecting member 222 further includes a snap screw 2224, which can pass through the small hole portion of the stepped hole and be threadedly connected to the internal thread of the column 22222. This can improve the connection strength between the buckle 2221 and the column 22222, and avoid the problem of failure of the press buckle 2222 due to the loosening of the buckle 2221 and the column 22222.
