Description

Technical Field

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

[0002] Strength training equipment has a wide range of applications, offering users diverse training modes based on its built-in training devices. In strength training equipment, the training bar is tightly connected to the resistance device via a traction component, providing the user with a stable grip point and ensuring smooth transmission of resistance from the resistance device during strength training.

[0003] Typically, existing technology uses adjustable adjustment components on a training bar, allowing traction devices to connect to the bar and meet the different adjustment needs of various trainees. However, once the adjustment component is installed on the training bar, its range of motion is often limited. Especially to ensure a secure lock-on, the adjustment component is generally designed to move only in the axial direction, not in the circumferential direction. Particularly when multiple traction devices are connected to the training bar, their circumferential connection positions differ, potentially leading to variations in the force exerted by each device on the bar. Therefore, users may need to adjust their body posture or force application during training, increasing the difficulty, affecting the continuity and smoothness of the workout, and even potentially causing sports injuries. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a training bar assembly and a strength training device that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Firstly, a training bar assembly is provided, comprising:

[0007] The training rod body has an adjustment rod at at least one end;

[0008] An adjusting member is movably disposed on the adjusting rod, the adjusting member being configured to allow sliding along the axial direction of the adjusting rod;

[0009] A connector for connecting a traction component of a strength training device, the connector being movably disposed on the adjusting component and configured to allow rotation about the circumference of the adjusting rod;

[0010] A locking structure is also provided between the adjusting member and the connecting member to restrict the rotation of the connecting member relative to the adjusting member.

[0011] The training rod uses an adjusting rod to guide the adjusting component axially, so that the axial position of the traction component connection can be adjusted by the movement of the adjusting component and the adjusting rod. At the same time, a connecting component that can be adjusted circumferentially is set on the adjusting component, so that the rotation angle of the traction component connection can be adjusted by the adjusting component and the connecting component, which meets the needs of actual training scenarios and ensures the training effect.

[0012] As an optional implementation, the locking structure includes:

[0013] A first locking part, wherein multiple first locking parts are arranged circumferentially on the adjusting member; and

[0014] A second locking part is disposed on the connector, and the second locking part is configured to allow limiting engagement with any of the first locking parts.

[0015] As an optional implementation, the first locking part is configured as a locking groove formed on the outer periphery of the adjusting member, and the second locking part is configured as a stop block located on the connecting member;

[0016] The stop block can move between a locked position and a released position; when the stop block is in the locked position, at least a portion of the stop block can be located within the locking groove; when the stop block is in the released position, the stop block disengages from the locking groove.

[0017] As an optional implementation, a limiting structure is further provided between the adjusting member and the connecting member, the limiting structure being used to restrict the relative movement of the adjusting member and the connecting member in the axial direction;

[0018] The limiting structure includes a first limiting part and a second limiting part respectively disposed on the adjusting member and the connecting member. The first limiting part and the second limiting part are mutually limiting and engaged, and at least one of them is disposed around the circumference.

[0019] Based on the fact that the connector and the adjusting component can rotate and lock around the circumference, a limiting structure is further set to ensure that the connector and the adjusting component are in a stable fit relationship in the axial direction. This ensures the fit strength between the two components while allowing the locking structure to stably provide locking and unlocking functions.

[0020] As an optional implementation, the first limiting part is configured as a limiting groove surrounding the adjusting member in a circumferential direction, and the second limiting part is configured as a limiting block located on the connecting member;

[0021] The limiting block can move between a locked position and a released position; when the limiting block is in the locked position, at least a portion of the limiting block can be located within the limiting groove; when the limiting block is in the released position, the limiting block disengages from the limiting groove.

[0022] As an optional implementation, the adjusting member has an adjusting hole, and the adjusting member is slidably sleeved on the adjusting rod through the adjusting hole;

[0023] The connector has a movable hole, and the connector is movably fitted onto the adjusting member through the movable hole. The locking structure is provided on the outer periphery of the adjusting member and partly on the wall of the movable hole.

[0024] The interconnected components, adjusting parts, and adjusting rods improve the stability of their fit by nesting together, while effectively saving the installation space of the training rod assembly in the axial direction and reducing the possibility of interference between the training rod assembly and other related parts of the strength training equipment.

[0025] As an optional implementation, the adjusting member and the adjusting rod are movably connected via a threaded pair.

[0026] As an optional implementation, the thread helix angle of the threaded pair is set to be greater than the friction angle.

[0027] As an optional implementation, there are two adjusting rods, which are respectively located at opposite ends of the training rod body and each is provided with an adjusting member, and each adjusting member is provided with a connecting member;

[0028] The threaded pair located between the two adjusting rods and the two adjusting members has opposite rotation directions.

[0029] Secondly, a strength training device is provided, comprising:

[0030] The training bar assembly as described in the first aspect; and

[0031] A base, wherein a resistance device is provided within the base, and the resistance device is connected to the connector via a traction member.

[0032] The beneficial effects of this utility model are as follows: The training bar assembly, by incorporating an adjusting member that allows for axial adjustment, further includes a connecting member. This connecting member provides the connection position for the traction member, which can be adjusted by rotating the connecting member relative to the adjusting member in a circumferential direction. This enhances the flexibility of adjusting the connection position between the training bar body and the traction member, meeting the personalized needs of different trainees. It also ensures that the traction member provides the optimal force transmission path during training, improving training efficiency and effectiveness, and reducing the risk of sports injuries caused by improper positioning.

[0033] The locking structure ensures that the relative position between the connector and the adjusting component remains fixed after the connector has been rotated and adjusted, preventing the connector from rotating with the adjusting component without cause. This ensures that the training rod assembly has good structural stability during use, guaranteeing the safety and effectiveness of training. Attached Figure Description

[0043] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model are further described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] Strength training equipment is an indispensable tool in the modern fitness field. Its applications are extremely wide-ranging, and through built-in training devices, it can simulate various training modes to meet diverse user fitness needs. Among strength training equipment, the training bar, as the key component in direct contact between the user and the equipment, plays a crucial role. The design of the training bar not only affects the user's training experience but also directly impacts training effectiveness and safety.

[0047] As can be seen from the background technology, in the design and application of strength training equipment, existing technologies generally adopt a scheme of configuring adjustable components on the training bar. The aim of this design is to allow the traction component to be flexibly connected to the training bar via the adjustable component, thereby precisely meeting the personalized adjustment needs of different trainees for the connection position of the traction component. However, this design has revealed certain limitations in practical applications.

[0048] Specifically, once the adjustment component is installed on the training bar, its range of motion is often restricted. In order to ensure that the adjustment component can be securely locked to the training bar during training and to avoid safety hazards or poor training results due to loosening, the adjustment component is usually designed to be able to slide and adjust only in the axial direction.

[0049] While this design ensures the stability of the adjustment components to some extent, it sacrifices their ability to adjust their position in the circumferential direction. This limitation is particularly pronounced in complex scenarios where the training bar needs to connect to multiple traction components. Because the connection positions of each traction component in the circumferential direction of the training bar are different, the magnitude and direction of the forces they exert on the training bar will inevitably differ. This difference may not only require the trainee to adjust their body posture or force application method to adapt to the different mechanical sensations brought by different traction components, thus increasing the difficulty and complexity of the training; it may also affect the continuity and smoothness of the training due to improper body posture or uncoordinated force application method, and even increase the risk of sports injuries to some extent.

[0050] For example, when performing certain training movements that require precise control of the force transmission path, if the connection position of the traction device is not correct, the trainee may need to twist their body or change the angle of force application to try to achieve the ideal training effect. This unnatural body posture and force application method is not only difficult to sustain, but may also cause unnecessary pressure and damage to joints, muscles and other parts of the body.

[0051] Alternatively, in cases where the training bar is connected to multiple traction components, due to initial assembly differences or assembly errors, the multiple traction components located on the training bar may not be able to pull the traction component synchronously in the same direction after the connection positions of the traction components are properly adjusted (for example, when doing squats, the traction components connected to both ends of the training bar should have the same traction direction), resulting in unscientific force application.

[0052] In view of this, this embodiment provides a training bar assembly that can be applied to strength training equipment. By adding a connecting member 40 between the adjusting member 30 and the traction member 50, and setting the connecting member 40 to be able to move and adjust in a circumferential direction relative to the adjusting member 30, the problem of the difficulty in adjusting the connection position of the traction member 50 and the low degree of freedom in traditional training bars can be solved.

[0053] The training bar assembly is used in strength training equipment, including but not limited to dumbbell racks and barbell racks, rowing machines, pull-up machines, and power stations. In these devices, the training bar assembly serves as a support point, allowing trainees to perform strength training with various weights. Furthermore, the training bar assembly can be detached from the relevant strength training equipment, enabling its use on different types of equipment. Thus, this invention, by designing the adjusting rod 20 assembly as a connector 40 for connecting the traction member 50, allows for circumferential adjustment relative to the adjusting member 30, thereby meeting the connection requirements of different strength training equipment for the training bar assembly.

[0054] Please refer to the instruction manual attached. Figures 1-5 The training bar assembly includes a training bar body 10, at least one end of which is provided with an adjustment rod 20. The training bar body 10 serves as the reference and support point for the entire training bar assembly, providing a part that the trainee can directly grip.

[0055] It is understood that this embodiment does not impose strict limitations or requirements on the relative position and relative structural state of the adjustment member 30 and the training rod body 10.

[0056] Furthermore, the training bar body 10 and the adjustment bar 20 are typically made of high-strength, corrosion-resistant metal materials, such as high-quality steel, aluminum alloy, or stainless steel, so that the training bar assembly can withstand the high load generated during training while maintaining structural stability and durability.

[0057] Based on the aforementioned structure of the training bar body 10, the training bar assembly of this embodiment further includes an adjusting member 30. The adjusting member 30 is movably disposed on the adjusting rod 20 and is configured to allow sliding along the axial direction of the adjusting rod 20. This aims to improve the flexibility, adaptability, and functionality of the training bar assembly and meet the diverse training needs of users. Specifically, taking an embodiment where the adjusting member 30 is connected to a traction member 50 while allowing sliding along the axial direction of the adjusting rod 20 as an example, this design allows the connection point of the traction member 50 on the training bar body 10 to be adjusted along the axial direction of the training bar body 10, allowing users to easily adjust the axial position of the traction member 50 on the training bar body 10 according to their height, training needs, or equipment configuration.

[0058] In addition, this embodiment also includes a connector 40, which is used to connect the traction member 50 of the strength training equipment and is responsible for transmitting and converting force. That is, in order to ensure that the axial position of the traction member 50 on the adjusting rod 20 is adjustable, the connector 40 needs to be set on the adjusting member 30 so that the connector 40 can move with the movement of the adjusting member 30. In this way, the connector 40 can transmit the training resistance provided by the resistance device of the strength training equipment to the adjusting member 30 through the traction member 50, and further transmit it to the trainee through the adjusting rod 20 and the training bar body 10, so that the trainee can resist the resistance source by operating the training bar body 10, thereby achieving the relevant training purpose.

[0059] It should be understood that in the design of strength training equipment, the resistance device is the key component that provides training resistance. It can be, but is not limited to, a weight stacking resistance source (adjusting the resistance by adding or removing counterweights), an elastic resistance source (using the deformation of elastic materials such as springs and elastic bands to generate resistance), a pneumatic cylinder resistance source (providing resistance through the gas pressure inside the pneumatic cylinder), or an electromagnetic resistance source (generating resistance through changes in the electromagnetic field).

[0060] Following the above embodiments, the traction component 50 may, but is not limited to, use components such as wire ropes, traction belts, and chains. In some embodiments, the traction component 50 is typically coupled to the base 60 of the strength training equipment via a pulley system. The pulley system includes multiple pulleys rotatably mounted on the base 60. By winding the traction component 50 around the corresponding pulleys, the pulleys can change the direction of resistance and reduce frictional losses during resistance transmission.

[0061] Specifically, the connector 40 and the adjusting member 30 are movably connected. The connector 40 is configured to rotate around the circumference of the adjusting rod 20, allowing the user to adjust the rotation angle of the traction member 50 around the adjusting rod 20 according to training needs. This changes the position of the connection point of the traction member 50 on the connector 40 relative to the circumference of the adjusting rod 20. By adjusting the relative angle between the connector 40 and the adjusting rod 20, trainees can simulate various training movements, such as pulling, pushing, and lifting at different angles, thus comprehensively exercising all parts of the body. The flexibility of the connector 40 also allows the training bar assembly to be adapted to various strength training equipment, including cable trainers, functional training racks, and other types of fitness equipment. Stable connection and effective training can be achieved through the connector 40, enhancing the adjustability of the connection position between the training bar body 10 and the traction member 50 and meeting the personalized needs of different trainees for the connection position of the traction member 50.

[0062] For example, in an embodiment where the training bar assembly has at least two connectors 40 and an adjusting member 30, the number of traction members 50 is the same as the number of connectors 40, and each traction member 50 is connected to each connector 40. The circumferential adjustment of the connectors 40 relative to the adjusting members 30 not only achieves the above-mentioned functions, but more importantly, in this embodiment, each adjusting member 30 can be adjusted independently to adjust the spacing between the traction members 50. Simultaneously, each connector 40 can also be adjusted independently relative to the adjusting member 30 in a circumferential direction to adjust the relative position of the connection points of the traction members 50 in the circumferential direction. This ensures that the connection points of the traction members 50 are aligned circumferentially on the adjusting rod 20, thereby guaranteeing that the force applied by each traction member 50 on the training bar body 10 is in the same direction, and that the force exerted by each traction member 50 on the training bar assembly is essentially consistent. This allows the traction members 50 to provide the optimal force transmission path during the user's training process, helping to improve training efficiency, enhance training effects, and reduce the risk of sports injuries caused by improper positioning.

[0063] Furthermore, in actual use scenarios of strength training equipment, users can quickly and conveniently adjust the position of the traction component 50 connection without disassembling and reinstalling the connector 40 and the adjuster 30. Trainees can freely install the adjuster 30, which is equipped with the connector 40, on the adjuster rod 20 without worrying about the specific position of the traction component 50 connection. After the adjuster 30 finishes its adjustment on the adjuster rod 20, the position of the connector 40 in the circumferential direction can be further adjusted. This allows the axial position and circumferential position adjustment of the traction component 50 connection to be completed on the training rod body 10 (adjuster 30). This can significantly improve the continuity and smoothness of strength training and reduce the number of times trainees have to interrupt their training due to equipment adjustments.

[0064] Building upon the addition of the connecting member 40 described above, to ensure the stability of the connecting member 40 relative to the adjusting member 30 after adjustment and to prevent circumferential movement of the traction member 50 (connection point) during training, a locking structure is further provided between the adjusting member 30 and the connecting member 40 in this embodiment to restrict the rotation of the connecting member 40 relative to the adjusting member 30. In this embodiment, the locking structure can mechanically (e.g., bolts, clips, friction locks, etc.) securely fix the connecting member 40 to the adjusting member 30, preventing the connecting member 40 from retaining the freedom of rotation around the circumference after adjustment.

[0065] After adjusting the angle of connector 40, the locking structure ensures that connector 40 remains in the position set by the user. During strength training, the locking structure withstands the tension applied by the user and the vibration of the equipment, ensuring the overall stability of the training bar and avoiding training interruptions or safety hazards caused by loosening.

[0066] For example, the locking component in the training rod assembly can adopt various types of locking methods, specifically including but not limited to the following locking methods:

[0067] Bolt locking, achieved by the engagement of a bolt and a threaded hole (or nut), tightly secures the adjusting member 30 or the connecting member 40 together. The bolt passes through the threaded hole of one of the adjusting member 30 or the connecting member 40 and engages with a locking structure such as a retaining hole or groove on the other, thereby locking the two together. By unscrewing the bolt from the threaded hole, disengaging it from the corresponding retaining structure, the adjusting member 30 and the connecting member 40 can be unlocked, allowing the connecting member 40 to regain its circumferential freedom of movement.

[0068] The latching mechanism enables the connector 40 to be quickly locked and unlocked on the adjuster 30. In some embodiments, the latching mechanism is typically designed with an elastic structure. When the latching mechanism on the connector 40 aligns with the corresponding slot or protrusion on the adjuster 30, pressing or rotating the latch causes it to engage in the slot or protrusion, thus achieving locking. Applying a force in the unlocking direction to the latching mechanism allows it to overcome the elasticity of the structure and disengage from the corresponding slot or protrusion, restoring the connector 40 to a state with circumferential freedom of movement.

[0069] Friction locking is achieved by increasing the friction between the connector 40 and the adjusting member 30. For example, a friction plate or rubber pad can be placed between the connector 40 and the adjusting member 30. When the adjusting member 30 slides to the desired position, tightening the screws or knobs on the connector 40 increases the pressure between the friction plate and the adjusting member 30, thereby generating sufficient friction to prevent the connector 40 from rotating. Conversely, when adjustment of the connector 40 is needed, the trainee can release the adjusting member 30 by operating the friction plate, causing the connector 40 to lose the friction between itself and the adjusting member 30, restoring it to a state with circumferential freedom of movement.

[0070] Pin locking is achieved by providing pin holes on both the connector 40 and the adjusting member 30, and locking and unlocking are accomplished by inserting and removing the pin.

[0071] Magnetic locking utilizes the attractive force of magnets to achieve locking. Magnets or magnetic materials are respectively placed on the connector 40 and the adjusting member 30. When the connector 40 rotates to the desired position, the attractive force between the magnets fixes the connector 40 on the adjusting member, achieving relative fixation in the circumferential direction. When the connector 40 needs to be adjusted relative to the adjusting member 30, the trainee can apply a force to the connector 40 in a specific direction to overcome the magnetic attraction between the magnets, thereby allowing the connector 40 to be adjusted circumferentially on the adjusting member 30.

[0072] It is worth noting that in the actual application scenarios of strength training equipment, the choice of locking method depends on the specific needs of the training bar assembly and the usage environment. For example, for situations requiring the bearing of large tensile forces, bolt locking or pin locking can be selected; for situations requiring quick adjustment and locking, snap locking, magnetic locking, friction locking, etc., can be selected. This embodiment does not impose specific limitations or requirements on this.

[0073] In the above embodiments, the existence of the locking structure ensures that the relative position between the connecting member 40 and the adjusting member 30 remains fixed after the rotation adjustment is completed, preventing the connecting member 40 from rotating with the adjusting member 30 without cause, so that the training rod assembly has good structural stability in use, and ensures the safety and effectiveness of training.

[0074] Please continue to refer to the instruction manual appendix. Figures 2-4 To ensure a secure locking function, in one optional embodiment, the locking structure includes a first locking part 31 and a second locking part 41 respectively disposed on the adjusting member 30 and the connecting member 40. Multiple first locking parts 31 and second locking parts 41 may be provided. For example, if multiple first locking parts 31 are provided, they are arranged circumferentially on the adjusting member 30. The trajectory of the second locking parts 41 disposed on the connecting member 40 as it moves circumferentially coincides with the trajectory connecting each of the first locking parts 31. During the circumferential adjustment of the connecting member 40 on the adjusting member 30, the second locking parts 41 sequentially pass through each of the first locking parts 31, ultimately allowing the second locking parts 41 to move to the corresponding position with the connecting member 40 and form a locking engagement with the corresponding first locking part 31.

[0075] Correspondingly, multiple second locking parts 41 can be provided. Multiple second locking parts 41 are arranged around the circumference of the connector 40, and the trajectory formed by the connection of multiple second locking parts 41 is consistent with the movement trajectory of the first locking part 31 in the circumference direction. During the movement of each second locking part 41 with the connector 40 around the circumference, the second locking parts 41 can maintain at least one second locking part 41 in a state of corresponding and locking with the first locking part 31 according to the specific rotation angle of the connector 40.

[0076] This embodiment takes an example where multiple first locking parts 31 are provided on the adjusting member 30. According to the above-described principle of the arrangement of the first locking parts 31 and the second locking parts 41, multiple first locking parts 31 are arranged in the circumferential direction on the adjusting member 30, providing multiple selectable locking positions for the second locking parts 41. When the second locking parts 41 are configured to allow limiting cooperation with any of the first locking parts 31, the connecting member 40 can be locked with the adjusting member 30 from multiple angles, improving the flexibility and diversity of training.

[0077] It should be noted that the specific structural forms of the first locking part 31 and the second locking part 41 provided in this embodiment can be, but are not limited to, the locking methods listed above. For example, in the embodiment using bolt locking, the first locking part 31 and the second locking part 41 are respectively configured as the threaded hole and the bolt, and the bolt is rotatably and adjustablely disposed on the connector 40, while multiple threaded holes are arranged at intervals around the circumference of the adjusting member 30, so that when the bolt rotates with the connector 40 to a position corresponding to any threaded hole, the bolt can be screwed into the corresponding threaded hole, forming a locking fit between the connector 40 and the adjusting member 30; while in the embodiment using snap-locking, the first locking part 31 and the second locking part 41 can be respectively configured as the snap-locking mechanism and the slot (or protrusion), with multiple slots arranged around the circumference. With the adjusting member 30, after the locking mechanism rotates with the connecting member 40 to the corresponding angle, the locking mechanism can engage with the corresponding slot to lock the connecting member 40 and the adjusting member 30 in the circumferential direction. In the embodiment of friction locking, the first locking part 31 and the second locking part 41 can be respectively set as the friction plate and the friction surface that engages with the friction plate. At this time, the friction surface can be continuously wrapped around the adjusting member 30 (or the connecting member 40) in the circumferential direction. After the connecting member 40 is rotated to any angle, the trainee can achieve circumferential locking of the connecting member 40 and the adjusting member 30 by controlling the friction point to press against the friction surface at the corresponding position.

[0078] In practical applications, trainees can rotate the connector 40 to the position aligned with the desired first locking part 31 according to training needs. Then, through active operation (such as pressing, rotating, etc.) or passive operation (such as the action of an elastic structure), the second locking part 41 is driven to achieve a limiting engagement with the first locking part 31, thereby achieving the purpose of restricting the circumferential rotational freedom of the connector 40 on the adjusting part 30.

[0079] By arranging multiple first locking parts 31 along the circumference, the connecting part 40 can be locked with the adjusting part 30 from multiple angles, allowing the training rod assembly to meet the needs of different training movements and angles, improving the flexibility and diversity of training. Trainees can also choose to cooperate the second locking part 41 with any one of the first locking parts 31 according to their own training needs and preferences, thereby realizing personalized training settings.

[0080] It should be noted that the reason why multiple first locking parts 31 are provided in this embodiment is that, in actual application scenarios, the connector 40 needs to provide the trainee (user) with a position to hold and operate the device to rotate in a circumferential direction. In other words, the part of the connector 40 exposed outside the training rod assembly is more than that of the adjustment part 30. Therefore, by providing multiple first connectors 40, multiple first connectors 40 can be effectively hidden between the connector 40 and the adjustment part 30 as much as possible, which improves the overall visual effect of the training rod assembly and reduces the possibility of interference to the trainee when multiple second locking parts 41 are provided.

[0081] Furthermore, the fact that there is only one second locking part 41 and it can be limited and cooperate with any first locking part 31 makes it easier for the trainee to lock and unlock the connector 40. Compared with locking and unlocking the connector 40 and the adjustment part 30 by operating the first locking part 31, and by setting multiple second locking parts 41, the user only needs to operate one second locking part 41 to lock or unlock it with the corresponding first locking part 31. The operation is simple and convenient, effectively improving the operating efficiency of the training bar assembly, reducing its operating difficulty, and lowering the threshold for using strength training equipment.

[0082] Please continue to refer to the instruction manual appendix. Figures 3-4 As an optional specific structural form of the locking structure, the first locking part 31 is configured as a locking groove formed on the outer periphery of the adjusting member 30, and the second locking part 41 is configured as a stop block located on the connecting member 40. The shape and size of the locking groove must be configured to allow the stop block to engage, ensuring that the connecting member 40 and the adjusting member 30 can be locked together by the first locking part 31 and the second locking part 41. The stop block can move between a locked position and a released position. Specifically, when the stop block is in the locked position, at least a portion of the stop block can be located within the locking groove, and when the stop block is in the released position, the stop block disengages from the locking groove.

[0083] It should be understood that this embodiment does not limit the specific connection method between the second locking part and the connecting member 40. That is, the second locking part 41 and the connecting member 40 can be detachably connected or non-detachably connected. A detachable connection allows the stop block and the connecting member 40 to be separated and reconnected when needed, facilitating maintenance, replacement, or adjustment. For example, the stop block and the connecting member 40 can be connected by a threaded connection, but not limited to a threaded connection. The stop block is connected to the connecting member 40 through a threaded structure, and the stop block passes through a threaded hole on the connecting member 40, so that the stop block can be inserted into or disengaged from the corresponding locking groove during the threaded adjustment on the connecting member 40, thereby completing the locking and unlocking of the connecting member 40 and the adjusting member 30. In addition, the stop block and the connecting member 40 can also adopt a snap-fit ​​connection. In this embodiment, the stop block and the connecting member 40 are respectively provided with mutually cooperating snap-fit ​​structures, and the adjustment of the stop block on the connecting member 40 is achieved by pressing or rotating. Of course, the stop block and the connector 40 can also be connected by means such as magnetic attraction or pin connection, which will not be further described or limited in this embodiment. In the embodiment where the stop block is connected to the connector 40 by a detachable connection, the trainee can switch the stop block between the locked and released positions by operating the stop block to change its relative position with the connector 40, thereby locking and unlocking the connector 40 on the adjusting member 30. When the stop block and the connector 40 are connected by a non-detachable connection, it means that the stop block and the connector 40 cannot be easily separated after manufacturing or assembly. This is usually used in situations where long-term fixation is required and frequent disassembly and adjustment are not necessary. The two can be connected by, but are not limited to, welding, riveting, integral molding, adhesive bonding, etc. In the implementation method where the two are connected by this cooperation, the trainee can adjust the stop block in different positions by operating the connector 40 to drive the stop block. The trainee can apply a force in a specific direction to the connector 40 so that it can drive the stop block to move between the locked position and the released position, thereby locking and unlocking the connector 40 on the adjuster 30.

[0084] In the above scheme, the first locking part 31 is set as a locking groove on the outer periphery of the adjusting member 30, and the second locking part 41 is set as a stop block located on the connecting member 40. The stop block can move between the locked position and the released position relative to the connecting member 40, so that the stop block can be engaged into the corresponding locking groove or disengaged from the corresponding locking groove. In addition to satisfying the requirement that the relative position between the connecting member 40 and the adjusting member 30 can be flexibly adjusted, the cooperation between the locking groove and the stop block realizes a reliable lock between the connecting member 40 and the adjusting member 30. This locking method can withstand the tension and vibration during the training process, ensuring the safety and stability of the training.

[0085] Furthermore, during the actual operation of the stop block, the trainee can switch the stop block between the locked and released positions simply by operating it (such as rotating or pressing), without the need for complicated tools or steps. This effectively reduces the difficulty of operating the connector 40 on the adjuster 30 and improves the adjustment efficiency of the connector 40.

[0086] Specifically, such as Figures 3-4 As shown, in this embodiment, the first locking part 31 is configured as a plurality of locking grooves arranged in a circumferential direction on the outer periphery of the adjusting member 30. Each locking groove is opened in the axial direction, so that the groove walls on opposite sides are arranged in a circumferential direction on the adjusting member 30. The second locking part 41 is configured as a screw that is threadedly engaged with the connecting member 40. The connecting member 40 has a first screw hole 44 with a position corresponding to the locking groove, so that the screw, which is the second locking part 41, can be screwed into it and pass through the first screw hole 44 into the corresponding locking groove. At this time, the part of the screw in the locking groove is regarded as the stop block mentioned above. The stop block is in the locking groove. When the connecting member 40 needs to rotate in a circumferential direction, the stop block can prevent the connecting member 40 from rotating by abutting against the groove wall of the locking groove, thereby locking the connecting member 40.

[0087] By configuring the first locking part 31 and the second locking part 41 as a screw and a locking groove, the processing and assembly difficulty of the training rod assembly can be effectively reduced. Only the first screw hole 44 and the locking groove need to be machined on the adjusting member 30 and the connecting member 40, respectively. Furthermore, the screw, which serves as the second locking part 41, can be a readily available component directly installed in the first screw hole 44. In addition, when the screw is installed in the first screw hole 44 and in the locked position, the screw head can abut against the surface of the connecting member 40, forming a stable fit between the screw and the connecting member 40. This effectively prevents the first locking part 31 from detaching from the locking groove without the trainee's operation, ensuring a good fit between the connecting member 40 and the adjusting member 30 during training, thus protecting the trainee's safety and reducing the risk of injury.

[0088] In some implementations, such as Figures 3-4 As shown, a limiting structure is also provided between the adjusting member 30 and the connecting member 40. The limiting structure and the locking structure are staggered in the axial direction of the adjusting rod 20 to avoid mutual interference between the limiting structure and the locking structure when the connecting member 40 is adjusted. In this embodiment, the limiting structure is used to restrict the relative movement of the adjusting member 30 and the connecting member 40 in the axial direction, ensuring that the connecting member 40 and the adjusting member 30 maintain a stable cooperation relationship. While realizing multi-angle adjustment at the connection of the traction member 50, it ensures that the locking structure between the connecting member 40 and the adjusting member 30 can continuously and effectively provide locking and unlocking functions.

[0089] Similar to the locking structure described above, the limiting structure includes a first limiting part 32 and a second limiting part 42 respectively disposed on the adjusting member 30 and the connecting member 40. Specifically, the first limiting part 32 is a limiting structure disposed on the adjusting member 30, used to cooperate with the second limiting part 42 to achieve a limiting function in the axial direction. In this example, the first limiting part 32 can be designed as an annular protrusion, groove, or other shape extending in the circumferential direction, depending on the cooperation method with the second limiting part 42. Furthermore, the first limiting part 32 must ensure that it does not interfere with the second limiting part 42 in the circumferential direction, thereby guaranteeing the relative freedom of movement between the adjusting member 30 and the connecting member 40 in the circumferential direction. Correspondingly, the second limiting part 42 is a limiting structure disposed on the connecting member 40, used to cooperate with the first limiting part 32. Its structure can match the first limiting part 32, such as being designed as an annular groove, partial or annular protrusion, etc., corresponding to the first limiting part 32.

[0090] When the connector 40 and the adjusting member 30 are engaged, the first limiting part 32 and the second limiting part 42 do not mutually limit each other in the circumferential direction, providing a corresponding degree of freedom for the relative movement of the adjusting member 30 and the connector 40 in the circumferential direction. They mutually restrict each other in the axial direction to prevent the adjusting member 30 and the connecting member 40 from disengaging in the axial direction. Thus, when the first limiting part 32 and the second limiting part 42 are engaged, they do not mutually limit each other in the circumferential direction, thereby providing a corresponding degree of freedom for the relative movement of the adjusting member 30 and the connecting member 40 in the circumferential direction. They only mutually restrict each other in the axial direction, ensuring the stability of the adjusting member 30 and the connecting member 40 in the axial direction and preventing them from disengaging due to axial force during training, thereby improving the safety and reliability of the component.

[0091] Following the above, the design of the limiting structure ensures that the locking structure can be locked and fixed after the relative rotation adjustment of the adjusting member 30 and the connecting member 40. This means that when the locking structure unlocks the connecting member 40, the connecting member 40 can maintain a stable fit with the adjusting member 30. No matter how the adjusting member 30 and the connecting member 40 rotate relative to each other, the locking structure can lock the connecting member 40 on the adjusting member 30, providing a stable connection for the training rod assembly.

[0092] In some embodiments, to allow the connector 40 to be detached from the adjuster 30, thereby meeting the needs of daily inspection, maintenance, and component replacement, the first limiting part 32 and the adjuster 30, and / or the second limiting part 42 and the adjuster 30, can be detachably assembled. This allows the first limiting part 32 and the adjuster 30 to be disassembled, and / or the second limiting part 42 and the connector 40 to be disassembled, so that the first limiting part 32 and the second limiting part 42 can disengage from their limiting engagement, thus satisfying the detachable requirement of the connector 40 on the adjuster 30. The first limiting part 32 and the adjuster 30, and / or the second limiting part 42 and the connector 40, can be connected by, but are not limited to, threaded connections, snap-fit ​​connections, pin connections, magnetic connections, etc., and this embodiment does not impose further limitations or requirements.

[0093] As an optional specific structural form, such as Figures 3-4 As shown, the first limiting part 32 is configured as a limiting groove surrounding the adjusting member 30 in the circumferential direction, and the second limiting part 42 is configured as a limiting block located on the connecting member 40. The size and shape of the limiting groove are configured to allow the limiting block to enter into it, so as to ensure that the limiting block and the limiting groove can exert a constraint on the connecting member 40 and the adjusting member 30 in the axial direction when they are in a mating state.

[0094] In this embodiment, to meet the requirement of detachable engagement between the connector 40 and the adjusting member 30, the limiting block can move between a locked position and a released position. When the limiting block is in the locked position, at least a portion of the limiting block can be located within the limiting groove. When the limiting block is in the released position, the limiting block disengages from the limiting groove. It is understood that the limiting structure in this embodiment is similar to the specific structural form of the locking structure described above. This embodiment does not limit the specific connection method between the second limiting part 42 and the connector 40 when the second limiting part 42 is movable relative to the connector 40. That is, the second limiting part 42 and the connector 40 can be detachably connected or non-detachably connected. In the embodiment where the limiting block is non-detachably disposed on the connector 40, the movement of the limiting block between the locked and released positions can be achieved by operating the connector 40. In the embodiment where the limiting block is detachably disposed on the connector 40, the switching between the locked and released positions of the limiting block can be achieved by directly operating the limiting block.

[0095] As described above, in the embodiment where the limiting block is detachably connected to the connector 40, the limiting block and the connector 40 can be connected by, but are not limited to, threaded connections, snap-fit ​​connections, magnetic connections, pin connections, etc. However, when the limiting block is non-detachably mounted on the connector 40, the limiting block and the connector 40 can be connected by, but are not limited to, welding, riveting, integral molding, adhesive bonding, etc.

[0096] In embodiments where the limiting block is detachably mounted on the connector 40, the specific structural form is similar to that of the locking structure, such as... Figures 3-4 As shown, the first limiting part 32 can be configured as a limiting groove opened around the circumference of the adjusting member 30, while the second limiting part 42 is configured as a screw that is threadedly engaged with the connecting member 40. The connecting member 40 has a second screw hole 45 with a position corresponding to the locking groove, so that the screw, which is the second limiting part 42, can be screwed into it and pass through the second screw hole 45 into the corresponding limiting groove. At this time, the part of the screw in the limiting groove is regarded as the aforementioned limiting block. Since the limiting groove is around the circumference, it allows the second limiting part 42 to move freely in the circumferential direction with the connecting member 40. When the connecting member 40 receives a circumferential force, the limiting block can prevent the connecting member 40 from making axial adjustments by abutting against the groove wall of the limiting groove.

[0097] Based on any of the above embodiments, in one embodiment, please refer to the appendix to the instruction manual. Figures 3-4 The adjusting member 30 has an adjusting hole 33, through which it is slidably fitted onto the adjusting rod 20 to ensure good connection strength between them. Correspondingly, the connecting member 40 has a movable hole 43, through which it is movably fitted onto the adjusting member 30. A locking structure is provided on the outer periphery of the adjusting member 30 and partially on the wall of the movable hole 43 to ensure good fit strength between them. In this embodiment, the nested arrangement between the adjusting member 30 and the adjusting rod 20, and between the connecting member 40 and the adjusting member 30, effectively improves the installation stability of the training rod assembly. Furthermore, the sequential fitting of the connecting member 40, the adjusting member 30, and the adjusting rod 20 saves installation space occupied by the adjusting member 30 and the connecting member 40 in the axial direction of the adjusting rod 20, thereby improving the overall structural compactness of the training rod assembly.

[0098] In some instances, the adjusting element 30 and the adjusting rod 20 are movably connected via a threaded pair. The threaded pair enables the transmission of force in both the circumferential and axial directions between the adjusting element 30 and the adjusting rod 20. Besides providing trainees with more operational options, as mentioned above, the physical characteristics of the threaded pair also ensure the continuity and smoothness of the transmission process. This provides trainees with a better operational experience when adjusting the training rod assembly, and also allows for higher adjustment precision between components. This ensures that the training rod assembly remains in a stable state after operation, meeting the requirements for subsequent strength training.

[0099] Furthermore, the threaded joint structure is relatively simple. It not only enables force transmission between components in both rotational and linear directions, but also allows for axial mutual constraint after adjustment. Specifically, when the traction member 50 applies a radial force to the adjusting member 30 through the connecting member 40, the adjusting member 30 and the adjusting rod 20 can achieve axial mutual constraint using the threaded joint. This eliminates the need for additional limiting mechanisms, making the training rod assembly easier to manufacture and maintain. Simultaneously, due to the large and uniformly distributed contact area between the threaded joints, it possesses good load-bearing capacity and wear resistance, thereby improving transmission reliability and service life, allowing the training rod assembly to meet the requirements of strength training equipment under different training resistances.

[0100] It is understandable that a threaded pair specifically refers to a mechanical connection structure achieved through thread engagement. It consists of two parts: an internal thread 331 and an external thread 22. The internal thread 331 and the external thread 22 engage together to form a tight connection or achieve relative movement. Therefore, the specific circumferential positions of the internal thread 331 and the external thread 22 in their respective axial positions are fixed and cannot be adjusted. At the connection point of the traction component 50, issues such as... Figure 5 The inconsistency in the circumferential direction shown means that when the adjusting member 30 is adjusted to a specific axial position using the threaded pair to the adjusting rod 20, it is impossible for it to make circumferential adjustments at the current axial position. This embodiment addresses this issue by providing a connecting member 40. The connecting member 40 serves to provide the connection position for the traction member 50 while being rotatable relative to the adjusting member 30 in the circumferential direction. This allows the trainee to adjust the circumferential position of the traction member 50's connection point on the adjusting rod 20 using the connecting member 40, thus compensating for the limitation of the adjusting member 30's inability to move circumferentially.

[0101] As an optional implementation, in the embodiment where the adjusting member 30 is movably connected to the adjusting rod 20 via a threaded pair, the thread helix angle of the threaded pair is set to be greater than the friction angle. This ensures that the thread pitch is sufficiently large while also eliminating the self-locking capability of the threaded pair. In this training rod assembly, the adjusting rod 20 and the adjusting member 30 can achieve axial sliding adjustment through relative rotation or direct axial pushing. This makes the axial adjustment of the adjusting member 30 simpler and more convenient, providing trainees with more operational options.

[0102] It should be understood that, as mentioned above, in the specific application scenario of strength training equipment, the training process of this training bar assembly is mainly subjected to the radial force from the threaded pair. Therefore, even if the thread helix angle of the threaded pair is set to be greater than the friction angle, causing it to lose its self-locking ability, in actual training conditions, the threaded pair will achieve axial locking under the radial force brought by the traction member 50, preventing the adjusting member 30 from moving relative to the adjusting rod 20 in the circumferential direction. This keeps the components in a stable relative positional relationship, ensuring that the training bar assembly remains stable during training, allowing the trainee to obtain good training results, and effectively preventing the trainee from being injured.

[0103] The threaded pair that has lost its self-locking ability can only achieve relative movement between the components when it is subjected to forces in the circumferential direction and the axial direction. That is, when the training rod assembly is in a non-training state, the trainee can adjust the relative position of the adjusting component 30 and the adjusting rod 20 by applying forces in the corresponding directions to the adjusting component 30 or the adjusting rod 20, thus ensuring the safety of the adjustment process.

[0104] Please continue to refer to the instruction manual appendix. Figure 1 , Figure 7 As mentioned in the above embodiments, multiple traction components 50 can be set to adapt to different training programs. This embodiment takes two traction components 50 as an example. Correspondingly, two adjusting rods 20 are set, with each adjusting rod 20 set at opposite ends of the training rod body 10 and equipped with an adjusting component 30. This allows the traction components 50 to act on the two adjusting rods 20 respectively, balancing the direction of the force applied to the training rod body 10. Each adjusting component 30 is equipped with a connecting component 40, allowing the two traction components 50 to be connected to the adjusting component 30 respectively. While the two adjusting components 30 act on both ends of the training rod body 10, the distance between the two traction components 50 can be adjusted through the adjusting component 30. Furthermore, the two traction components 50 can also adjust their connection position on the adjusting rod 20 by rotating the connecting component 40 on the adjusting component 30, thereby meeting the needs of different training programs and initial installation states.

[0105] In a specific implementation of the strength training equipment, the training bar assembly is connected to the two traction components 50 of the strength training equipment via connectors 40 at both ends. The two traction components 50 of the strength training equipment are also connected to the resistance device, which can transmit training resistance simultaneously. This connection method ensures that when the trainee holds both ends of the training bar body 10 with both hands, both arms can receive consistent training resistance, allowing the structure of the training bar assembly to meet the needs of more different training programs.

[0106] In some embodiments, the adjustment rod 20 and the training rod body 10 are on the same straight line, which makes the overall structure of the training rod assembly more compact. The entire adjustment rod 20 assembly is long and narrow, which can effectively reduce the risk of interference between the adjustment rod 20 assembly and the strength training equipment, while also improving the grip feel of the trainee during training.

[0107] Furthermore, by setting the adjustment rod 20 and the training rod body 10 on the same axis, the adjustment rod 20 and the training rod body 10 can transmit training resistance more efficiently. The training resistance applied by the resistance device can be efficiently transmitted to the corresponding limbs of the trainee through the traction member 50 via the training rod assembly, thereby effectively improving the training effect provided by the training rod assembly.

[0108] Based on the above implementation, a limiting platform 11 for restricting the adjusting member 30 is also provided between the training bar body 10 and the adjusting rod 20. The limiting platform 11 can effectively prevent the adjusting member 30 from sliding from the adjusting rod 20 to the training bar body 10, thereby avoiding the problem of interference between the adjusting member 30, the connecting member 40 and the traction member 50 and the trainee's limbs.

[0109] In one embodiment, the limiting platform 11 can be formed by setting the diameter of the training rod body 10 to be larger than that of the adjusting rod 20. In this embodiment, when the adjusting member 30 moves along the axial direction on the adjusting rod 20 to near the end of the training rod body 10, the adjusting member 30 can be constrained by abutting against the portion of the training rod body 10 that protrudes from the outer periphery of the adjusting rod 20. This eliminates the need to additionally set a limiting part on the training rod body 10 or the adjusting rod 20, thereby reducing the production cost of the training rod assembly and making the overall structure of the training rod assembly more compact.

[0110] It is understood that in some other embodiments, the end of the adjusting rod 20 away from the training rod body 10 may also be restricted by setting a limiting part to prevent the adjusting member 30 from disengaging from the end of the adjusting rod 20 away from the training rod body 10.

[0111] In this embodiment, a smooth rod section 21 is provided at the end of the adjusting rod 20 away from the training rod body 10, thereby effectively constraining both ends of the adjusting member 30 in the axial direction of the adjusting rod 20.

[0112] In some embodiments, such as Figures 1-3As shown, as a specific structural form, the connector 40 includes a sleeve portion 46 and a rope connecting portion 47. In the embodiment where the connector 40 is fitted onto the adjusting member 30, the sleeve portion 46 has a movable hole 43. The sleeve portion 46 is rotatably fitted onto the adjusting member 30 through the movable hole 43 to ensure good connection strength between the connector 40 and the adjusting member 30. Therefore, in the embodiment where the connector 40 has a first screw hole 44 and a second screw hole 45, both the first screw hole 44 and the second screw hole 45 are located in the sleeve portion 46 to ensure that both the locking structure and the limiting structure can stably constrain the connector 40 and the adjusting member 30 in their respective directions. One end of the rope connecting portion 47 is connected to the sleeve portion 46, and the other end of the rope connecting portion 47 is used to connect to the traction member 50 of the strength training equipment.

[0113] Correspondingly, the rope connection part 47 is provided with a connecting ring 48, which is connected to the traction component 50 of the strength training equipment.

[0114] In the embodiment where the adjusting member 30 and the adjusting rod 20 are guided by a threaded pair, the threaded pair includes an external thread 22 surrounding the outer periphery of the adjusting rod 20 and an internal thread 331 located within the adjusting hole 33. With the connecting member 40 connected to the traction member 50, thus restricting the degree of freedom of the adjusting member 30 to rotate circumferentially, the trainee can rotate the training rod body 10 while holding it, causing the adjusting rod 20 to rotate relative to the adjusting member 30. This allows the external thread 22 on the outer periphery of the adjusting rod 20 to spirally push the internal thread 331 within the adjusting hole 33, ultimately achieving the purpose of the connecting member 40 moving axially towards or away from the training rod body 10 according to the rotation direction of the adjusting rod 20. Of course, the trainee can also hold the connector 40 and apply a force to the connector 40 in the axial direction of the adjusting rod 20, so that the internal thread 331 in the adjusting member 30 pushes the external thread 22 on the outer circumference of the adjusting rod 20 in the opposite direction, so that the adjusting rod 20 and the training rod body 10 rotate under the drive of the thread pair, and at the same time achieve the effect of the connector 40 moving axially on the adjusting rod 20, thus meeting the need to provide multiple operating methods.

[0115] In one embodiment, such as Figure 6As shown, the length L1 of the external thread 22 in the axial direction of the adjusting rod 20 is set to be less than the overall length L2 of the adjusting rod 20. Furthermore, the external thread 22 is located on the adjusting rod 20 near the end where it connects to the training rod body 10. Thus, when the adjusting member 30 moves to the end of the adjusting rod 20 away from the training rod body 10 via the threaded pair, the connecting member 40 is constrained by the threaded pair, preventing it from disengaging from the end of the adjusting rod 20 away from the training rod body 10, achieving the corresponding limiting effect. By placing the external thread 22 at the end of the adjusting rod 20 where it connects to the training rod body 10, the adjusting member 30 can be assembled with the adjusting rod 20 from that end when the adjusting rod 20 is disengaged from the training rod body 10. When the adjusting rod 20 is reassembled to the training rod body 10, it can be constrained by the limiting platform 11 between the training rod body 10 and the adjusting rod 20.

[0116] It is worth mentioning that in the above embodiment where both the adjusting rod 20 and the connecting member 40 are provided in pairs, the screw threads between the two adjusting rods 20 and the two adjusting members 30 have opposite directions of rotation. Thus, when the training rod body 10 is rotated to adjust the corresponding position of the adjusting member 30 on the adjusting rod 20, the two adjusting members 30 can move in opposite directions. When the two adjusting members 30 are held and moved in opposite directions along the axial direction, the training rod body 10 and the two adjusting rods 20 can rotate synchronously, thereby achieving the purpose of adjusting the distance between the two connecting members 40.

[0117] Please refer to the instruction manual attached. Figure 7 This embodiment also provides a strength training device. In addition to using the training bar assembly provided in any of the above embodiments, the strength training device of this embodiment also includes a base 60. The base 60 serves as the supporting foundation of the strength training device and is usually made of a relatively high-strength material to ensure that it can withstand the huge forces generated during training.

[0118] In practical applications, the base 60 can be set on any supporting structure (such as an equipment bracket) such as the ground or wall, according to the training program to be provided by the strength training equipment. The base 60 is equipped with a resistance device, which is connected to the connector 40 through the traction member 50.

[0119] In this embodiment, the base 60 is placed on a support platform such as the ground. The upper part of the base 60 has a footrest 61 for the trainee to step on. Resistance devices (not shown) are respectively installed at opposite ends of the footrest 61 on the base 60. A rope outlet 62 is provided on the upper side of the base 60 corresponding to the positions of the two resistance devices, connecting to their lower sides. Each resistance device passes through the rope outlet 62 via a traction member 50 and is connected to the connectors 40 at both ends of the training bar assembly. The training bar assembly can adjust the position of the two connectors 40 according to the distance between the positions where the two traction members 50 pass through the base 60, thereby ensuring that the training resistance transmitted by the traction members 50 is substantially perpendicular to the training bar body 10, thus guaranteeing the training effect.
