[0002] Weights on gym equipment refer to the adjustment of training intensity by adding or removing weights to achieve the goal of muscle building. The choice of weights should be determined based on an individual's physical condition, strength level, and training goals. For example, beginners should start with lighter weights and gradually increase the weight to avoid injury and improve training effectiveness.

[0003] When choosing fitness equipment, safety is a crucial consideration. The size and number of weight plates are also important indicators of weight quality. The mainstream adjustment method, pin-type adjustment, relies on the number of weight plates to adjust the load; however, its accuracy is limited to a minimum adjustment unit of 2.5KG, making it unsuitable for progressive load requirements. Furthermore, while improved solutions like electric adjustment can achieve this, the power source restricts its applicability and is relatively expensive.

[0004] In response to the above situation, this equipment overcomes the aforementioned shortcomings, providing a new option for both new and experienced fitness enthusiasts. Summary of the Invention

[0046] Guide rod 1 extends vertically and its top end is connected to the fitness equipment;

[0047] An auxiliary counterweight sleeve 2 is fitted onto the guide rod 1 and connected to the top of the guide rod 1 via a lifting connection structure; the auxiliary counterweight sleeve 2 can move vertically downward relative to the guide rod 1 to adjust the counterweight of the fitness equipment.

[0048] Specifically, at least one auxiliary counterweight sleeve is set as needed, and a weight load is preset on the auxiliary counterweight sleeve. Users can adjust it to a weight that suits their own needs for exercise. If they want to increase the force during exercise, they can push the cylinder of the hook plate upward to avoid it, and release it to allow the counterweight to fall down under gravity to increase the force. Together with the counterweight component, the weight can be adjusted, which is more precise than the traditional method of adjusting the weight simply by the number of counterweight plates. This application achieves timely power response through the weight of the auxiliary counterweight sleeve itself, and the accuracy can be adjusted according to the auxiliary counterweight sleeve to break through the minimum adjustment unit.

[0049] Based on the above scheme, the pull-up connection structure includes a guide rod fixing seat 3, a hook plate 4, and a connecting plate 5.

[0050] The guide rod fixing seat 3 is fixedly connected to the fitness equipment; one end of the hook plate 4 is movably connected to the guide rod fixing seat 3 through the first connector 402, and can rotate around the first connector 402.

[0051] The connecting plate 5 is fixedly connected to the auxiliary counterweight sleeve 2, and the connecting plate 5 is movably connected to the other end of the hook plate 4.

[0052] Based on the above scheme, a second connector 404 is also included.

[0054] Based on the above scheme, the guide rod fixing seat 3 includes a guide rod fixing seat base plate 301 and a guide rod fixing seat ear plate 302.

[0055] The guide rod fixing base plate 301 is connected to the fitness equipment; the top end of the guide rod 1 is fixedly connected to the guide rod fixing base plate 301; the guide rod fixing ear plate 302 is disposed at both ends of the guide rod fixing base plate 301 in the horizontal direction; and is movably connected to the hook plate 4.

[0056] The bottom plate 301 of the guide rod fixing seat and the ear plate 302 of the guide rod fixing seat form an upward-opening "U"-shaped structure.

[0057] Based on the above scheme, the hook plates 4 are arranged in pairs on both sides of the guide rod fixing seat 3, and a connecting crossbar 303 is provided between the two hook plates 4.

[0058] Based on the above scheme, the hook plate 4 is provided with a hook groove 401 at one end near the auxiliary counterweight sleeve 2.

[0059] Based on the above solution, the connecting plate 5 includes:

[0060] The connecting plate base plate 501 is sleeved on the guide rod 1 and fixedly connected to the auxiliary counterweight sleeve 2;

[0061] Connecting plate ear plates 502 are disposed at both ends of the connecting plate base plate 501 in the horizontal direction; the connecting plate base plate 501 and the connecting plate ear plates 502 form an upward-opening "U" shaped structure;

[0062] The connecting post 503 is set on the connecting plate ear plate 502 and is set in correspondence with the hook groove 401.

[0064] Based on the above solutions, the following are also included:

[0065] The fastening connecting sleeve 8 is sleeved between the auxiliary counterweight sleeve 2 and the guide rod 1, and is located below the auxiliary counterweight sleeve 2. In specific implementations, the fastening connecting sleeve 8 can be a nylon sleeve.

[0066] Specifically, the auxiliary counterweight sleeve 2 first needs to install the fastening connecting sleeve 8 in the auxiliary counterweight sleeve 2 to restrict the fit between the hole and the shaft, then connect the connecting plate 5 with bolts, then connect the guide rod fixing seat 3 to the hook plate 4, and use the second connecting piece 404 to limit the hook plate 4. Finally, push the fastening connecting sleeve 8 up to the maximum and release it. The auxiliary counterweight sleeve 2 will be locked by its own weight, and then use bolts to connect it to the guide rod to complete the installation.

[0067] This application also provides a fitness device, including a frame 6, a counterweight assembly 7, and the lifting auxiliary counterweight mechanism of this application.

[0068] The counterweight assembly 7 is disposed on the frame 6 to provide the load required for fitness; the upper end of the lifting auxiliary counterweight mechanism of this application is connected to the frame and located above the counterweight assembly 7, and works with the counterweight assembly to adjust the overall load required for fitness.
