Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a force enhancer for fitness equipment with stable adjustment function. Background Technology

[0002] There are many fitness equipment available, and weight-based fitness machines are among the most commonly used. For example, Chinese utility model patent CN211912576U discloses a strength enhancer for fitness equipment, including a sealed weight cabinet. A pull rod is installed at the center of the sealed weight cabinet, and first guide rods are symmetrically fixed on both sides of the pull rod inside the sealed weight cabinet. At least one weight is placed inside the sealed weight cabinet, and the weight is fitted onto the outside of the first guide rod and the pull rod, and can move up and down along the first guide rod.

[0003] However, the above-mentioned device still has the following drawbacks: First, since the weights are stacked and stored in a closed weight cabinet, it is complicated and inconvenient to change weights of different weights during actual operation, which increases the difficulty of adjusting the training intensity.

[0004] Secondly, since the weights are in direct contact with each other, collisions between adjacent weights are easily caused when adjusting or moving them. This can lead to surface wear and may also affect the integrity of the weight structure, thereby reducing the lifespan and stability of the entire fitness equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a strength enhancer for fitness equipment with stable adjustment function in order to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A strength enhancer for fitness equipment with stable adjustment function includes a base and weights. The weights are stacked on the base. Several fixed rods are fixedly connected to the top of the base. A top plate is detachably connected to the top of the fixed rods. Several guide rods passing through the weights and the base are fixedly connected to the bottom of the top plate. An inverted U-shaped pull rod is arranged on the top of the top plate, passing through the top plate and the weights. A T-shaped insert is detachably connected between the pull rod and the weights.

[0008] As a further description of the above technical solution:

[0009] The top of the fixing rod is fixedly fitted with a boss that abuts against the bottom of the top plate, and the top of the fixing rod is connected to a first nut that abuts against the top of the top plate by a threaded connection.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the guide rod is connected by a third nut that abuts against the bottom of the base via a threaded connection.

[0012] As a further description of the above technical solution:

[0013] The weight has a waist-shaped hole in its center along its radial direction. The vertical ends of the pull rod have insertion holes aligned with the waist-shaped hole. The insertion rod passes through the waist-shaped hole and the insertion holes. The free end of the insertion rod is connected to a second nut by a threaded connection.

[0014] As a further description of the above technical solution:

[0015] Each set of weights has several pads attached to its bottom.

[0016] As a further description of the above technical solution:

[0017] The base has through slots arranged radially thereon.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4This utility model provides a technical solution: a strength enhancer for fitness equipment with stable adjustment function, including a base 1, which serves as the foundation of the entire device and provides stable support; weights 3 are stacked on the base 1, and several fixing rods 2 are fixedly connected to the top of the base 1. A top plate 7 is detachably connected to the top of the fixing rods 2, and a boss 21 that abuts against the bottom of the top plate 7 is fixedly sleeved on the top of the fixing rods 2. A first nut 8 that abuts against the top of the top plate 7 is threadedly connected to the top of the fixing rods 2. The fixing rods 2, through the boss 21 and the first nut 8, firmly fix the top plate 7 at a certain height, ensuring the stability of the overall structure; several guide rods 4 that pass through the weights 3 and the base 1 are fixedly connected to the bottom of the top plate 7, and a third nut 11 that abuts against the bottom of the base 1 is threadedly connected to the bottom of the guide rods 4. The guide rods 4 pass through all the weights 3 and the base 1, and are connected to the third nut 11. The fixed design further enhances the overall structural stability. An inverted U-shaped pull rod 6, penetrating both the top plate 7 and the weight 3, provides a stable grip point, allowing users to exercise safely and effectively. The pull rod 6 can also be connected to fitness equipment to achieve corresponding functions. A T-shaped insert rod 5 is detachably connected between the pull rod 6 and the weight 3. A waist-shaped hole 301 is radially formed in the center of the weight 3. Insert holes 601, aligned with the waist-shaped hole 301, are formed on the vertical ends of both sides of the pull rod 6. The insert rod 5 passes through the waist-shaped hole 301 and the insert hole 601. A second nut 10 is threadedly connected to the free end of the insert rod 5. Users can quickly replace or adjust weights 3 of different weights by removing the second nut 10 and the T-shaped insert rod 5 to meet different training intensity requirements. For example, assuming a weight 3 weighs 5kg, refer to... Figure 1 In the state (with 5 weights 3), when the user's strength requires 3 weights 3 to meet the requirement, the first weight 3 and the third weight 3 can be fixed to the pull rod 6 from top to bottom through two sets of plug rods 5 and the second nut 10.

[0029] Furthermore, the components of this device are connected by detachable methods such as threaded engagement, which not only facilitates assembly and disassembly but also allows users to flexibly adjust the configuration of the weights 3 as needed.

[0030] Specifically, such as Figure 1 As shown, each set of weights 3 has several feet 9 glued to its bottom. First, the feet 9 are usually made of materials with a certain degree of elasticity and wear resistance, which not only prevents the weights 3 from directly contacting each other and causing wear, but also protects the surfaces of the weights 3 and the base 1 from damage, extending the service life of the equipment. In addition, the feet 9 can absorb and buffer the impact force generated during the exercise to a certain extent, thereby reducing the noise level and providing users with a quieter and more comfortable exercise environment. Second, due to the presence of the feet 9, even when the weights 3 are replaced, the neatness and stability of the weights 3 stack can be guaranteed, reducing the tilting or instability caused by improper placement of the weights 3.

[0031] Specifically, such as Figure 1 As shown, the base 1 has a through groove arranged radially thereon, which provides a direct passage for the installation and removal of the third nut 11.

[0032] Working principle: In use, firstly, by removing the second nut 10 and the T-shaped insert 5, weights 3 of different weights can be quickly replaced or adjusted to meet different training intensity requirements. For example, assuming a weight 3 weighs 5kg, refer to... Figure 1 In the state (with 5 weights 3), when the user's strength requires 3 weights 3 to meet the needs, the first weight 3 and the third weight 3 are fixed to the pull rod 6 from top to bottom through two sets of plug rods 5 and the second nut 10. During this process, the pads 9 can prevent the weights 3 from directly contacting each other and causing wear, thus extending the service life of the equipment. They can also absorb and buffer the impact force generated during the exercise to a certain extent, thereby reducing the noise level and providing the user with a quieter and more comfortable exercise environment.

[0033] Secondly, when it is necessary to replace the weight 3, remove the first nut 8 and the third nut 11, remove the pull rod 6, the top plate 7 and the guide rod 4 from the stacked weight 3, and reconfigure the weight 3 of the corresponding weight. In this process, the pad 9 can ensure the neatness and stability of the stacked weight 3, and reduce the tilting or instability caused by improper placement of the weight 3.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
