[0016] The present invention will be further described below with reference to specific embodiments.

[0017] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0018] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0019] like Figs. 1-3 As shown, the counterweight fine-tuning device described in this embodiment includes a fine-tuning block 61 and a locking device 63. The locking device 63 is fixedly connected to the fine-tuning block 61 via an L-shaped connector 62. The fine-tuning block 61 is located above the counterweight block 4, and the weight of the fine-tuning block 61 is less than that of the counterweight block 4. When the counterweight fine-tuning device 6 is not in use, the locking device 63 can lock the counterweight fine-tuning device 6 to the upper part of the frame 1. When it is necessary to fine-tune the counterweight, the counterweight fine-tuning device 6 can be stacked on top of the counterweight block 4.

[0020] In this embodiment, the locking device 63 includes a locking pin 631 and a locking sleeve 632. The locking pin 631 passes through the locking sleeve 632 and is elastically connected to the locking sleeve 632 by a spring 633. The fine-tuning block 61 is provided with a clearance hole 611 to avoid the movable pulley 3 and the cable 2.

[0021] The fitness equipment with a counterweight fine-tuning device described in this embodiment includes a frame 1, a guide rod 5 fixed on the frame 1, a counterweight 4 passing through the guide rod 5 and movable up and down along the guide rod 5, and the counterweight 4 being connected to the handle end through multiple pulleys and a cable 2; a counterweight fine-tuning device 6 is slidably connected to the guide rod 5.

[0022] The upper crossbar of the frame 1 is provided with a locking hole 11, which cooperates with the locking pin 631 to lock the counterweight fine-tuning device 6. A movable pulley 3 is provided above the counterweight block 4, and a pull rod 31 is connected to the bottom of the movable pulley 3. The pull rod 31 passes through the center hole on the counterweight block 4, and the counterweight block 4 is connected to the movable pulley 3 through the pull rod 31, thereby transmitting gravity to the handle end.

[0023] The method of using this utility model is as follows:

[0024] When fine-tuning of the counterweight is required, pull the locking pin 631 backward to disengage it from the locking hole 11, and then place the counterweight fine-tuning device 6 directly on top of the counterweight block 4. At this time, pulling the handle end can move the counterweight block and the counterweight fine-tuning device 6 together. When the fine-tuning device is not in use, the counterweight fine-tuning device 6 can be moved upward to the horizontal bar at the top of the frame 1, and the counterweight fine-tuning device can be locked to the top of the frame 1 by the locking device 63.
