In some embodiments, the first connecting member 130 and/or the second connecting member 230 on the outer side further have a limiting member 700 thereon. When the strength training machine is unfolded, the limiting member 700 abuts against the surface of the third connecting member 320 facing the use side of the weight mechanism 400, that is, the limiting member 700 abuts against the surface of the third connecting member 320 facing the top of the first bracket 100 or the second bracket 200. Thus, the first bracket 100 and the second bracket 200 are prevented from being folded reversely, and a limit is provided for unfolding the strength training machine. In a specific implementation, the limiting member 700 may be a cylinder or a limiting member.

In the folding process of the strength training machine, the stress points are concentrated on the first connecting piece 130 and the second connecting piece 230, so the supporting piece 1000 can be arranged to increase the strength of the first connecting piece 130 and the second connecting piece 230.

The positioning shaft 950 is connected to the first link 120 or the support rib 140 of the first link 120. The damper 960 and the sleeve 930 are sleeved on the guide shaft 940, the magnetic element 910 is connected to a first end of the sleeve 930, and the damper 960 abuts against a second end of the sleeve 930. When the strength training machine is in a folded state, the magnetic element 910 drives the sleeve 930 to slide along the axial direction of the guide shaft 940, and the sleeve 930 gradually releases the pressure applied to the buffer 960 until the magnetic element 910 is attracted to the magnetic attraction member 920. When the strength training machine is in the unfolded state, the first end of the sleeve 930 abuts against a supporting surface (e.g., the ground) of the strength training machine, and the magnetic element 910 drives the sleeve 930 to slide along the axial direction of the guide shaft 940, so that the sleeve 930 abuts against the buffer 960, and applies pressure to the buffer 960, so that the sleeve 930 is flush with the bottom surface of the first bracket 100, and the bottom surface of the first bracket 100 is ensured to contact with the supporting surface of the strength training machine.

The buffer 960 may be one of a foam pad, a rubber pad, or a spring.

In the present application, the second connecting assembly 900 is used to connect the first bracket 100 and the second bracket 200, and the push rod structure 800 is used to separate the first bracket 100 and the second bracket 200. The second connecting assembly 900 and the pusher structure 800 may be adjacently disposed, whereby the pusher structure 800 facilitates separation of the first bracket 100 and the second bracket 200.

Optionally, in the strength training machine provided in the embodiment of the present application, the bottom and/or the sidewall of the weight mechanism 400 has a sliding pad 410 or a pulley 420. Wherein the pulley 420 may be a universal wheel. By arranging the sliding pad 410 or the pulley 420 at the bottom of the weight mechanism 400, the sliding pad 410 or the pulley 420 plays a role in assisting movement during the unfolding process or the folding process of the strength training machine, so that the strength training machine can be unfolded and folded conveniently. The sliding pad 410 or the pulley 420 is disposed on the side wall of the weight mechanism 400, and when the strength training machine is folded to be in an upright state, the sliding pad 410 or the pulley 420 on the side wall of the weight mechanism 400 contacts with the supporting surface of the strength training machine, thereby facilitating the movement of the folded strength training machine.

Optionally, at least two foot pads 430 are disposed at the bottom of the weight mechanism 400, and when the strength training machine is in the unfolded state, the foot pads 430 contact with the supporting surface of the strength training machine, so as to provide a cushion for the strength training machine when the strength training machine is in use.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
