Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a training bar mechanism and fitness equipment. Background Technology

[0002] In recent years, people have been paying more and more attention to health, and more and more people are willing to join the ranks of fitness enthusiasts, which has led to the rapid development of the fitness industry and a gradual increase in the demand for fitness equipment.

[0003] In related technologies, fitness equipment can include strength training machines, such as the Smith machine; strength training machines can include a bar mechanism, with pull ropes connected to both ends of the bar mechanism. When the user pulls the bar mechanism, the pull ropes can generate tension on the bar mechanism to achieve a training effect. Different users have different body shapes, and in some cases, the user needs to adjust the position of the pull ropes relative to the bar mechanism before training.

[0004] However, when users adjust the position of the pull rope relative to the training rod mechanism, they need to first release the pull rope from the training rod mechanism, then move the pull rope to the fixed position, and finally fix the pull rope relative to the training rod mechanism, which is a relatively complicated operation. Utility Model Content

[0005] The present invention aims to provide a training bar mechanism and fitness equipment to solve the technical problem of the complexity of adjusting the position of the stretching bar relative to the training bar mechanism in the prior art.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution: One embodiment of this utility model provides a training bar mechanism, including: Training bar body; A pull-cord connection assembly includes a body, a limiting component, and a triggering component. The triggering component and the limiting component are both installed on the body. The triggering component is linked with the limiting component to control the locking or releasing of the limiting component. When the limiting component is locked, the body is axially fixed relative to the training rod body. When the limiting component is released, the body can slide axially relative to the training rod body.

[0007] In some embodiments, the limiting component includes a limiting member and a first elastic reset member, the limiting member being slidably connected to the body, and the first elastic reset member being connected between the limiting member and the body; The triggering component includes a trigger member slidably connected to the body and abutting against the limiting member. When the user applies force to the trigger member, the trigger member slides relative to the body and pushes the limiting member away from the training rod body, causing the first elastic reset member to compress and the limiting member to release. When the user removes the force on the trigger member, the first elastic reset member resets and causes the limiting member to move toward the training rod body, locking the limiting member.

[0008] In some embodiments, the triggering component further includes a second elastic reset member, which is connected between the triggering component and the body; When the trigger slides relative to the body and pushes the limiting member to move away from the training rod body, the second elastic reset member is compressed.

[0009] In some embodiments, the body has a first guide cavity and a second guide cavity that are interconnected. The limiting member is slidably connected in the first guide cavity, the first elastic reset member is connected between the limiting member and the cavity wall of the first guide cavity, the trigger member is slidably connected in the second guide cavity, and the second elastic reset member is connected between the trigger member and the cavity wall of the second guide cavity; the first guide cavity is perpendicular to the second guide cavity.

[0010] In some embodiments, the trigger includes a guide plate, the upper side of which includes a guide plane and a guide ramp connected in sequence. The guide plane is parallel to a horizontal plane, and the height of the guide ramp gradually decreases in the direction from the guide ramp to the limiting member. The limiting member includes an abutting surface. When the limiting member is locked, the guide ramp abuts against the abutting surface; when the limiting member is released, the guide plane abuts against the abutting surface.

[0011] In some embodiments, the number of guide plates is two; the limiting member includes a guide post, a connecting block and a limiting block, the guide post is connected to the upper side of the connecting block, and the first elastic reset member is sleeved on the guide post; the limiting block is connected to the lower side of the connecting block, and the lower side of the connecting block includes two abutting surfaces, the two abutting surfaces being located on opposite sides of the limiting block respectively; The trigger includes two guide plates, which are located on opposite sides of the limiting block; each guide plate corresponds to one abutment surface.

[0012] In some embodiments, the first guide cavity extends through the upper side of the body, and the guide post can extend or retract from the upper end of the first guide cavity.

[0013] In some embodiments, the trigger further includes a pressing part and a side plate, the second guide cavity extends through one side of the body, the same end of the two guide plates is connected to the pressing part, the pressing part extends out of the second guide cavity, the other opposite ends of the two guide plates are connected to the side plate, and the second elastic reset member is connected between the side plate and the cavity wall of the second guide cavity.

[0014] In some embodiments, the training rod body has multiple slots, the limiting member includes a locking block, and the first guide cavity extends through the lower side of the body; When the limiting component is locked, the card block extends out of the first guide cavity and inserts into one of the card slots; when the limiting component is released, the card block disengages from the card slot and is received in the second guide cavity.

[0015] In some embodiments, the training rod body has a plurality of circumferentially arranged slots, and when the limiting component is locked in the slots, the pull rope connecting assembly can rotate circumferentially along the training rod body.

[0016] In some embodiments, the training rod body includes a first connecting rod and two second connecting rods. The diameter of the first connecting rod is larger than the diameter of the second connecting rods. The two second connecting rods are respectively connected to opposite ends of the first connecting rod. The slot is formed on the second connecting rod. The slot closest to the first connecting rod is spaced apart from the first connecting rod, so that the triggering component (26) is at a preset distance from the end of the first connecting rod (12).

[0017] Another embodiment of this utility model provides a fitness device, including the training bar mechanism in any of the above embodiments.

[0018] Compared to existing technologies, users can adjust the position of the pull rope connection component relative to the main body of the training bar according to their own situation or training movements before using the training bar mechanism, so that users can maintain good training movements during training.

[0019] Using the training rod mechanism of this application, when the user adjusts the position between the pull rope connecting assembly and the training rod body, the triggering component first controls the release of the limiting component, allowing the pull rope connecting assembly to slide axially relative to the training rod body. Then, the user slides the pull rope connecting assembly relative to the training rod body to the desired fixed axial position. Afterward, the user can control the limiting component to lock via the triggering component, thus fixing the body axially relative to the training rod body, completing the position adjustment of the pull rope connecting assembly. In this embodiment, although the pull rope connecting assembly undergoes a certain degree or varying degrees of circumferential rotation during axial sliding, the training rod mechanism of this application does not require circumferential alignment to achieve position adjustment of the pull rope connecting assembly. The user only needs to operate the triggering component to lock and release the limiting component relative to the training rod body, making it easier for the user to adjust the relative position of the pull rope connecting assembly and the training rod body.

[0023] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0025] The following detailed description, in conjunction with all the accompanying drawings, describes a training bar mechanism 100 and fitness equipment provided in this application through specific embodiments.

[0026] One embodiment of this utility model discloses a fitness equipment, which may include a frame, a training bar mechanism 100, a counterweight mechanism, and pull ropes. The counterweight mechanism is mounted on the frame, and the pull ropes connect the counterweight mechanism and the training bar mechanism 100. The counterweight mechanism may include a motor-driven mechanism that provides pulling force, or it may include a counterweight block connected to a pulley system. There may be two counterweight mechanisms and two pull ropes. One pull rope connects one counterweight mechanism to one end of the training bar mechanism 100, and the other pull rope connects the other counterweight mechanism to the other end of the training bar mechanism 100. When the user holds and pulls the training bar mechanism 100, the counterweight mechanism generates pulling force on the user through the pull ropes, thereby achieving a training effect.

[0027] Please refer to Figure 1 and Figure 2 The training bar mechanism 100 includes a training bar body 10 and a pull rope connection assembly 20. The pull rope connection assembly 20 includes a body 22, a limiting component 24, and a triggering component 26. The triggering component 26 and the limiting component 24 are both installed on the body 22. The triggering component 26 is linked with the limiting component 24 to control the locking or releasing of the limiting component 24. When the limiting component 24 is locked, the body 22 is axially fixed relative to the training bar body 10. When the limiting component 24 is released, the body 22 can slide axially relative to the training bar body 10.

[0028] With the above structure, before using the training bar mechanism 100 for training, the user can adjust the position of the two pull rope connecting components 20 relative to the training bar body 10 according to their own situation or training movements, so that the user can maintain good training movements for training.

[0029] Using the training rod mechanism of this application, when the user adjusts the position between the pull rope connecting assembly 20 and the training rod body 10, the user can first control the release of the limiting component 24 by the trigger component 26, allowing the pull rope connecting assembly 20 to slide axially relative to the training rod body 10. Then, the user slides the pull rope connecting assembly 20 relative to the training rod body 10 to the desired fixed axial position. Afterward, the user can control the limiting component 24 to lock by the trigger component 26, thus fixing the body 22 axially relative to the training rod body 10, completing the position adjustment of the pull rope connecting assembly. In this embodiment, although the pull rope connecting assembly 20 undergoes a certain degree or varying degrees of circumferential rotation during axial sliding, the training rod mechanism 100 of this application does not require circumferential alignment to achieve the position adjustment of the pull rope connecting assembly. The user only needs to operate the trigger component 26 to lock and release the limiting component 24 relative to the training rod body 10, making it easier for the user to adjust the relative position of the pull rope connecting assembly 20 and the training rod body 10.

[0030] Specifically, in this embodiment, the training rod body 10 may include a straight rod with a circular cross-section. The diameters at both ends of the training rod body 10 are smaller, while the diameter at the middle part of the training rod body 10 is larger. Multiple slots 102 are respectively provided at both ends of the training rod body 10. The number of pull rope connecting assemblies 20 can be two, and the two pull rope connecting assemblies 20 are respectively connected to the opposite ends of the training rod body 10.

[0031] The main body 22 may include a collar-like structure so that the main body 22 can be fitted onto the training bar body 10. The main body 22 may include a collar structure formed by splicing multiple parts together. The limiting member 24 may include a structure that can extend or retract the main body 22. When the limiting member 24 extends out of the main body 22 and is engaged in the slot 102, the limiting member 24 is locked and the main body 22 is axially fixed relative to the training bar body 10. When the limiting member 24 retracts into the main body 22, the limiting member 24 is released and the main body 22 can slide axially relative to the training bar body 10.

[0032] In some embodiments, the slot 102 can be an annular slot that runs through the circumference of the training rod body 10, so that the limiting component 24 can be inserted into the slot 102 at any circumferential angle. In some embodiments, the slot 102 can be a non-annular slot that does not run through the circumference of the training rod body 10. Even so, the non-annular slot is provided with a certain length along the circumference of the training rod body 10, such as extending to half the circumference of the entire circumference of the training rod body 10. In this way, it can also make it easier for the user to adjust the relative position of the pull rope connecting component 20 and the training rod body 10.

[0033] The limiting member 24 may include a compression spring connected to the body 22. The compression spring provides elastic force for other parts of the limiting member 24 to extend out of the body 22. The triggering member 26 may include a structure for pushing the limiting member 24 to move. When the triggering member 26 pushes the limiting member 24, the limiting member 24 can retract into the body 22. When the triggering member 26 does not push the body 22, the limiting member 24 can extend out of the body 22.

[0034] In other embodiments, the training rod body 10 may also include other structures, such as rod-shaped structures with other cross-sectional shapes, such as rectangular or elliptical; the number of pull rope connecting components 20 may also be one, which may be connected to a pull rope and located at one end of the training rod body 10, and another pull rope may be fixed to the other opposite end of the training rod assembly; the body 22 may also include other structures, such as a block structure connected to the training rod body 10 via a slide rail; the triggering component 26 and the limiting component 24 may also include other structures, such as the triggering component 26 including a button structure, and the limiting component 24 including a block structure connected to the button structure. When the user presses the button once, the limiting component 24 can extend out of the body, and when the user presses the button again, the limiting component 24 can retract into the body; the surface of the training rod body 10 may also have a smooth curved surface structure. When the limiting component 24 is released, the spring of the limiting component 24 can cause other parts of the limiting component 24 to press against the surface of the training rod body 10, so that the limiting component 24 is fixed relative to the training rod body 10.

[0035] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the limiting component 24 includes a limiting member 242 and a first elastic reset member 244. The limiting member 242 is slidably connected to the body 22, and the first elastic reset member 244 is connected between the limiting member 242 and the body 22.

[0036] The triggering component 26 includes a trigger member 262, which is slidably connected to the body 22 and abuts against the limiting member 242. When the user applies force to the trigger member 262, the trigger member 262 slides relative to the body 22 and pushes the limiting member 242 to move away from the training rod body 10, thereby compressing the first elastic reset member 244 and releasing the limiting member 24. When the user removes the force on the trigger member 262, the first elastic reset member 244 resets and drives the limiting member 242 to move toward the training rod body 10, locking the limiting member 24.

[0037] With the above structure, when the user applies force to the trigger 262 by pressing or other means, the trigger 262 can slide relative to the body 22 and push the limiting member 242 to slide relative to the body 22, so that the limiting member 24 is released; the limiting member 242 causes the first elastic reset member 244 to deform, and the elastic force applied by the first elastic reset member 244 to the limiting member 242 makes the limiting member 24 tend to lock.

[0038] When the user cancels the force applied to the trigger 262, the elastic force applied by the first elastic reset member 244 to the limiting member 242 causes the limiting member 242 to reset, thereby locking the limiting component 24 again. In this embodiment, the user only needs to apply force to the trigger 262 to control the release of the limiting component 24, and the limiting component 24 can automatically lock when the user stops applying force, further simplifying the operation difficulty when adjusting the relative position of the pull rope connection assembly 20 and the training rod body 10.

[0039] Specifically, in this embodiment, the limiting member 24 may include a column-like structure, the limiting member 242 is located inside the body 22, and the limiting member 242 moves vertically relative to the body 22; the first elastic reset member 244 may include a compression spring sleeved on the limiting member 242, the upper end of the first elastic reset member 244 may abut against the body 22, and the lower end of the first elastic reset member 244 may abut against the limiting member 242.

[0040] The trigger 262 can also be located inside the body 22, and the trigger 262 moves horizontally relative to the body 22. The height of the trigger 262 at different points in the horizontal direction can be different. The upper side of the trigger 262 can abut against the limiting member 242. During the movement of the trigger 262 relative to the body 22, when the higher part of the trigger 262 abuts against the limiting member 242, the limiting member 242 is lifted and retracted into the body 22, so that the limiting member 24 is released. When the lower part of the trigger 262 abuts against the limiting member 242, the limiting member 242 is lowered and extends out of the body 22, so that the limiting member 24 is locked.

[0041] In other embodiments, the limiting member 242 may also move relative to the trigger member 262 in other directions, such as tilting in the horizontal direction, and the trigger member 262 may also move relative to the trigger member 262 in other directions, such as the vertical direction.

[0042] In some embodiments, the triggering component 26 further includes a second elastic reset member 264, which is connected between the triggering component 262 and the body 22; when the triggering component 262 slides relative to the body 22 and pushes the limiting member 242 to move away from the training rod body 10, the second elastic reset member 264 is compressed.

[0043] With the above structure, when the trigger 262 slides relative to the body 22 and pushes the limiting member 242 to move away from the training rod body 10, the second elastic reset member 264 is compressed; the second elastic reset member 264 can also apply elastic force to the trigger 262, so that the trigger 262 has a tendency to slide in the opposite direction relative to the body 22. When the user removes the force on the trigger 262, the elastic force of the second elastic reset member 264 can drive the trigger 262 to reset, so that the limiting member 24 has a tendency to lock; when the first elastic reset member 244 and the second elastic reset member 264 work together, both the trigger 262 and the limiting member 242 are subjected to elastic force, making the locking of the limiting member 24 faster and reducing the possibility of jamming between the trigger 262 and the limiting member 242.

[0044] Specifically, in this embodiment, the second elastic reset member 264 may include a compression spring, and the extension direction of the second elastic reset member 264 may be parallel to the horizontal plane.

[0045] In other embodiments, the first elastic reset member 244 and the second elastic reset member 264 may also include other structures, such as spring sheets.

[0046] In some embodiments, the body 22 has a first guide cavity 2202 and a second guide cavity 2204 that are interconnected. A limiting member 242 is slidably connected in the first guide cavity 2202. A first elastic reset member 244 is connected between the limiting member 242 and the cavity wall of the first guide cavity 2202. A trigger member 262 is slidably connected in the second guide cavity 2204. A second elastic reset member 264 is connected between the trigger member 262 and the cavity wall of the second guide cavity 2204. The first guide cavity 2202 is perpendicular to the second guide cavity 2204.

[0047] With the above structure, the limiting member 242 is slidably connected to the first guide cavity 2202, and the cavity wall of the first guide cavity 2202 guides the limiting member 242, so that the limiting member 242 can slide more stably relative to the body 22; the trigger member 262 is slidably connected to the second guide cavity 2204, and the cavity wall of the second guide cavity 2204 guides the trigger member 262, so that the trigger member 262 can slide more stably relative to the body 22; thereby improving the stability of the limiting member 242 and the trigger member 262 when they move relative to the body 22.

[0048] Specifically, in this embodiment, the main body 22 may include a first mounting bracket 222, a second mounting bracket 224, and a cover plate 226. The first mounting bracket 222 may include a ring structure, and the lower side of the first mounting bracket 222 may be used to connect a cord. The second mounting bracket 224 may include a ring structure, and the second mounting bracket 224 may be sleeved on the training rod body 10. The first mounting bracket 222 may be sleeved on the outside of the second mounting bracket 224. The cover plate 226 may cover the upper side of the first mounting bracket 222. The cover plate 226 and the first mounting bracket 222 may be connected to each other by screws, and the first mounting bracket 222 and the second mounting bracket 224 may also be connected to each other by screws.

[0049] The first guide cavity 2202 can pass through the cover plate 226, the first mounting bracket 222, and the second mounting bracket 224 from top to bottom. The diameter of the portion of the first guide cavity 2202 that is opened in the cover plate 226 is smaller than the diameter of the portion of the first guide cavity 2202 that is opened in the first mounting bracket 222, so that the upper end of the first elastic reset member 244 can abut against the cover plate 226. The upper half of the second guide cavity 2204 is opened in the first mounting bracket 222, and the lower half of the second guide cavity 2204 is opened in the second mounting bracket 224.

[0050] The first guide cavity 2202 may include a cavity with a circular cross-section that is perpendicular to the horizontal plane, and the second guide cavity 2204 may include a cavity with a rectangular cross-section that is parallel to the horizontal plane. The first guide cavity 2202 and the second guide cavity 2204 are arranged to intersect each other.

[0051] In other embodiments, the cross-section of the first guide cavity 2202 may also be of other shapes, such as rectangular or elliptical; the cross-section of the second guide cavity 2204 may also be of other shapes, such as circular or polygonal.

[0052] In some embodiments, the trigger 262 includes a guide plate 2622. The upper side of the guide plate 2622 includes a guide plane 2624 and a guide ramp 2626 connected in sequence. The guide plane 2624 is parallel to the horizontal plane. In the direction from the guide ramp 2626 to the limiting member 242, the height of the guide ramp 2626 gradually decreases.

[0053] The limiting member 242 includes an abutment surface 2422. When the limiting member 24 is locked, the guide slope 2626 abuts against the abutment surface 2422. When the limiting member 24 is released, the guide plane 2624 abuts against the abutment surface 2422.

[0054] With the above structure, the guide plane 2624 is parallel to the horizontal plane; the guide plane 2624 is relatively low in height, and when the guide plane 2624 abuts against the abutting surface 2422, the abutting surface 2422 is also relatively low in height, allowing the lower end of the limiting member 242 to extend out of the body 22 and lock the limiting member 24. In the direction from the guide ramp 2626 to the limiting member 242, the height of the guide ramp 2626 gradually decreases; it can be inferred that in the direction away from the guide plane 2624, the height of the guide ramp 2626 gradually increases. As the guide ramp 2626 slides toward the limiting member 242, the guide ramp 2626 gradually pushes up the limiting member 242, causing the lower end of the limiting member 242 to retract into the body 22 and release the limiting member 24.

[0055] Specifically, in this embodiment, there can be two guide plates 2622, which are located on opposite sides of the trigger 262. The contact surface 2422 can be a plane parallel to the horizontal plane, the guide slope 2626 can be a planar structure inclined relative to the horizontal plane, and the side of the guide plate 2622 can be perpendicular to the horizontal plane.

[0056] In other embodiments, the number of guide plates 2622 may be only one, and the guide plate 2622 may be inserted into the limiting member 242; the abutment surface 2422 may also include an arc surface or an inclined plane; the guide slope 2626 may also include a slope with a certain curvature.

[0057] In some embodiments, there are two guide plates 2622; the limiting member 242 includes a guide post 2424, a connecting block 2426 and a limiting block 2428, the guide post 2424 is connected to the upper side of the connecting block 2426, and the first elastic reset member 244 is sleeved on the guide post 2424; the limiting block 2428 is connected to the lower side of the connecting block 2426, and the lower side of the connecting block 2426 includes two abutment surfaces 2422, which are located on opposite sides of the limiting block 2428.

[0058] The trigger 262 includes two guide plates 2622, which are located on opposite sides of the limiting block 2428; each guide plate 2622 corresponds to an abutment surface 2422.

[0059] With the above structure, the trigger 262 includes two guide plates 2622, which are located on opposite sides of the limiting block 2428. The two guide plates 2622 clamp the limiting block 2428, and thus, during the vertical movement of the limiting member 242 relative to the body 22, the guide plates 2622 can further guide the limiting block 2428, making the movement state of the limiting block 2428 more stable.

[0060] In addition, each guide plate 2622 corresponds to a contact surface 2422, and each guide plate 2622 can support the limiting member 242 on one side to prevent the limiting member 242 from shaking relative to the body 22 during movement.

[0061] Specifically, the guide post 2424 can have a cylindrical structure, and the connecting block 2426 can also have a cylindrical structure. The diameter of the guide post 2424 is smaller than the diameter of the connecting block 2426, and the guide member is coaxially arranged with the connecting block 2426. The limiting block 2428 can include a cuboid-like block structure. One side of the limiting block 2428 faces one guide plate 2622, and the other opposite side of the limiting block 2428 faces another guide plate 2622. The width of the connecting block 2426 is greater than the width of the limiting block 2428, so that both sides of the lower side of the connecting block 2426 protrude relative to the limiting block 2428 to form two abutment surfaces 2422.

[0062] Please refer to Figure 3 and Figure 6 In some embodiments, the first guide cavity 2202 extends through the upper side of the body 22, and the guide post 2424 can extend or retract from the upper end of the first guide cavity 2202.

[0063] With the above structure, when the limiting member 242 is stuck, the user can press the part of the guide post 2424 that extends out of the first guide cavity 2202 so that the limiting member 242 is released from the stuck state.

[0064] The diameter of the guide post 2424 can be adapted to the diameter of the portion of the first guide cavity 2202 that is opened in the cover plate 226, so that the guide post 2424 can extend or retract from the upper end of the first guide cavity 2202, that is, the guide post 2424 can extend or retract relative to the cover plate 226; the diameter of the portion of the first guide cavity 2202 that is opened in the first mounting bracket 222 is larger than the diameter of the guide post 2424, so that the cavity wall of the portion of the first guide cavity 2202 that is opened in the first mounting bracket 222 can accommodate the first elastic reset member 244 between the guide post 2424 and the cavity wall of the cavity wall of the first guide cavity 2202 that is opened in the first mounting bracket 222, and the upper end of the first elastic reset member 244 can abut against the cover plate 226.

[0065] In some embodiments, the trigger 262 further includes a pressing part 2628 and a side plate 2629. The second guide cavity 2204 extends through one side of the body 22. The same end of the two guide plates 2622 is connected to the pressing part 2628. The pressing part 2628 extends out of the second guide cavity 2204. The other opposite ends of the two guide plates 2622 are connected to the side plate 2629. The second elastic reset member 264 is connected between the side plate 2629 and the cavity wall of the second guide cavity 2204.

[0066] With the above structure, the pressing plate and the side plate 2629 can be located between the two guide plates 2622 to serve as a connection; in addition, the pressing part 2628 extends out of the second guide cavity 2204 so that the user can apply force to the trigger member 262 through the pressing part 2628; the second elastic reset member 264 is connected between the cavity wall of the side plate 2629 and the second guide cavity 2204, and the side plate 2629 can provide a connection space for the second elastic reset member 264.

[0067] Specifically, the pressing part 2628 may include a block structure with anti-slip texture, and the side plate 2629 may include a block structure similar to a cuboid. The pressing part 2628, the side plate 2629, and the two guide plates 2622 can be integrally formed; or the pressing part 2628 and the guide plate 2622, and the side plate 2629 and the guide plate 2622 can be connected to each other by dispensing or welding.

[0068] Please refer to Figure 1 and Figure 7 In some embodiments, the training rod body 10 has multiple slots 102, the limiting member 242 includes a locking block 2429, and the first guide cavity 2202 penetrates the lower side of the body 22.

[0069] When the limiting component 24 is locked, the locking block 2429 extends out of the first guide cavity 2202 and inserts into a slot 102; when the limiting component 24 is released, the locking block 2429 disengages from the slot 102 and is housed in the second guide cavity 2204.

[0070] With the above structure, when the limiting component 24 is locked, the locking block 2429 extends out of the first guide cavity 2202 and inserts into a slot 102, so that the locking relationship between the training rod assembly and the limiting component 24 is more secure when the limiting component 24 is locked. When the limiting component 24 is released, the locking block 2429 disengages from the slot 102 and is received in the second guide cavity 2204, so that the limiting component 24 can slide more easily relative to the training rod body 10 when the limiting component 24 is released.

[0071] Specifically, the card block 2429 may include a block-shaped structure similar to a cylinder, and the diameter of the card blocks 2429 may be smaller than that of the connecting block 2426. The opening on the lower side of the second guide cavity 2204 is formed to fit the shape of the card block 2429.

[0072] In some embodiments, the training bar body 10 has a plurality of circumferentially arranged slots 102. When the limiting component 24 is locked in the slots 102, the pull rope connecting assembly 20 can rotate circumferentially along the training bar body 10.

[0073] The slot 102 can be an annular slot, extending circumferentially along the training rod body 10. This allows the limiting component 24 to be easily inserted into the slot 102 at any circumferential angle, and facilitates the adaptive circumferential rotation of the axially fixed pull rope connection assembly 20 after insertion. In some embodiments, the slot 102 can be a non-annular slot, not extending circumferentially along the training rod body 10. Even so, the non-annular slot has a certain length along the circumference of the training rod body 10, such as extending to half the circumference of the training rod body 10. This allows users to more easily adjust the relative position of the pull rope connection assembly 20 and the training rod body 10, and also allows for the adaptive circumferential rotation of the pull rope connection assembly 20. This application does not specifically limit whether the slot 102 is an annular or non-annular slot, nor does it specifically limit the length of the non-annular slot extending circumferentially along the training rod body 10. The slot of this application can not only make the limiting component 24 easy to insert into the slot 102 at any or most circumferential angles, but also enable the axially fixed pull rope connection component 20 to adaptively rotate circumferentially during training.

[0074] Generally, the angle corresponding to a certain degree or different degree of circumferential rotation of the pull rope connecting component 20 during axial sliding is less than 360°, and the adaptive circumferential rotation angle of the pull rope connecting component 20, which is axially fixed during training, is also less than 360°. Therefore, the use of a non-circular slot fully meets the functional requirements of this application. Furthermore, for the technical solution using a non-circular slot, the non-circular slots on the training rod body are uniformly arranged, and the flush ends of the non-circular slots can also achieve circumferential positioning of the pull rope connecting component 20.

[0075] The slot 102 in this application not only facilitates the locking of the limiting component (24), making it easier to adjust the relative position of the pull rope connecting component 20 and the training rod body 10, but also meets the requirement of adaptive circumferential rotation of the pull rope connecting component 20 during training. Compared with the pin-and-hole locking mechanism, this application does not require an additional rotating component that can rotate relative to the body 22, and the positioning and locking operation is simpler.

[0076] In some embodiments, the spacing between each slot 102 corresponds to different training devices.

[0077] With the above structure, the pull rope connection component 20 can rotate circumferentially along the training rod body 10. When the user pulls the pull rope connected to the pull rope connection component 20 and starts training, it can drive the pull rope connection component 20 to rotate adaptively relative to the body 10, thereby reducing the circumferential resistance experienced by the user during training and improving the user's comfort during training.

[0078] Specifically, the body 22 of the pull rope connection assembly 20 may include a collar structure so that the pull rope connection assembly 20 can rotate circumferentially relative to the training bar body 10; the limiting member 24 includes a block structure that can extend and retract relative to the body 22, and the limiting member 24 can be inserted into the slot 102 when it extends out of the body 22; the limiting member 24 can be disengaged from the slot 102 when it retracts into the body 22.

[0079] In some embodiments, the training rod body 10 includes a first connecting rod 12 and two second connecting rods 14. The diameter of the first connecting rod 12 is larger than the diameter of the second connecting rods 14. The two second connecting rods 14 are respectively connected to opposite ends of the first connecting rod 12. A slot 102 is formed in the second connecting rod 14. The slot 102 closest to the first connecting rod 12 is spaced apart from the first connecting rod 12, so that the triggering component 26 is at a preset distance from the end of the first connecting rod 12.

[0080] With the above structure, the slot 102 is opened on the second connecting rod 14, and the diameter of the first connecting rod 12 is larger than the diameter of the second connecting rod 14; the body 22 of the pull rope connecting assembly 20 can be sleeved on the second connecting rod 14, and the end of the first connecting rod 12 can limit the pull rope connecting assembly 20 to prevent the pull rope connecting assembly 20 from detaching from the second connecting rod 14.

[0081] Additionally, there is a gap between the slot 102 closest to the first connecting rod 12 and the first connecting rod 12; this ensures that when the limiting member 24 is locked within the slot 102, the body 22 will not contact the first connecting rod 12, thus preventing the body 22 from experiencing additional friction. Alternatively, since the installation orientation of the pull cord connecting assembly 20 on the second connecting rod 14 is not limited, it is possible that the pull cord connecting assembly 20 can be installed in a manner that is... Figure 1 In the opposite orientation, that is, the triggering component 26 faces the end of the first connecting rod 12, if a preset distance is not reserved between the slot 102 closest to the first connecting rod 12 and the first connecting rod 12, the triggering component 26 may be abutted by the end of the first connecting rod 12, causing the limiting component 24 to be unlocked, thus bringing about a safety hazard.

[0082] Specifically, both the first connecting rod 12 and the second connecting rod 14 can include a cylindrical structure. The first connecting rod 12 and the two second connecting rods 14 can be coaxially arranged, and the length of the first connecting rod 12 can be greater than the length of the second connecting rod 14.

For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
