Detailed Description

As shown in fig. 2-8, the present invention discloses a matching structure of a swing arm and a slide rail of an exercise machine, which comprises a swing arm 10, a slide rail 20 and a pulley assembly 30; wherein, a containing cavity 21 with an opening is formed on the slide rail 20, and the opening of the containing cavity 21 is arranged along the length direction of the slide rail 20; the containing cavity 21 is provided with two side walls 211 and a bottom 212, and sliding grooves 22 arranged along the length direction of the sliding rails 20 are respectively arranged at the positions of the inner side surfaces of the two side walls 211 close to the bottom 212. One end of the swing arm 10 is hinged with the pulley assembly 30 and selectively folded in the accommodating cavity 21 of the slide rail 20; the pulley assembly 30 is slidably disposed at the bottom 212 of the receiving cavity 21, and the pulley assembly 30 is provided with a pulley 33 engaged with the sliding groove 22.

The utility model arranges a containing cavity 21 on the sliding rail 20, and the containing cavity 21 has a certain depth to contain the swing arm 10. And the present invention provides a sliding slot 22 near the bottom 212 of the receiving cavity 21 for engaging the pulley assembly 30. The sliding groove 22 may be formed by stamping on the inner wall of the receiving chamber 21. When a user holds the swing arm 10 to move, the swing arm 10 drives the pulley assembly 30 to slide in the sliding groove 22 under the action of external force. The accommodating cavity 21 is provided, and the position where the pulley assembly 30 is matched with the sliding chute 22 is arranged at the bottom 212 of the accommodating cavity 21, so that the stability of matching of the swing arm 10 and the sliding rail 20 is improved.

On the basis, the pulley assembly 30 comprises a connecting member 31 and two pulley fixing members 32, wherein the two pulley fixing members 32 are arranged along the length direction of the slide rail 20 and are respectively fixed at two ends of the connecting member 31; two ends of each pulley fixing piece 32 are connected with a pulley 33; the connecting piece 31 is hinged with the swing arm 10. Two sidewalls 331 and a tread 332 arranged between the two sidewalls 331 are arranged on the solid tire of the pulley 33, and an inclined surface 333 is formed between the sidewalls 331 and the tread 332; accordingly, the distance between the two slot edges of the slide slot 22 gradually increases from the bottom 212 of the slide slot 22 to the outside. The outline that this pulley 33 solid tire formed and the top surface clearance fit of spout 22 inner wall, the tread 332 of pulley 33 and the top surface clearance fit of spout 22 inner wall for pulley 33 both can smoothly slide in spout 22, receive the spacing of spout 22 two inside walls again, and can not cause swing arm 10 to produce the sensation of shaking, and by the slightly elastic solid tire of pulley can cushion the effort of swing arm 10 to slide rail 20 when training.

The swing arm 10 is hinged to the pulley assembly 30 through a hinge assembly, which is also disposed in the receiving space of the slide rail 20. The hinge assembly is the same as the conventional hinge structure and will not be described herein.

In this embodiment, in order to protect the hinge assembly and other accessories to a certain extent, the matching mechanism is further provided with a first hinge block and a second hinge block which are hinged to each other; swing arm 10 is equipped with expansion end 11 and stiff end 12, stiff end 12 be with pulley assembly 30 articulated one end, first articulated piece is located the stiff end 12 top at swing arm 10, the articulated piece of second is located swing arm 10's stiff end 12 below, and with pulley assembly 30 fixed connection. The first hinge block thus covers the hinge assembly and provides some protection thereto. When the swing arm 10 is opened, the fixed end 12 of the swing arm 10 pushes the first hinge block, thereby driving the first hinge block to swing compared with the second hinge block. When the swing arm 10 is folded, the first hinge block loses the driving force of the swing arm 10 and is also folded along with the first hinge block and is located on the fixed end 12 of the swing arm 10. The first hinge block also enables the exposed surface of the swing arm 10 to be relatively flat when the swing arm is in a folded state.

In summary, the key point of the present invention is that the sliding rail 20 is provided with a receiving cavity 21, and the receiving cavity 21 has a certain depth so that it can receive the swing arm 10. And the present invention provides a sliding slot 22 near the bottom 212 of the receiving cavity 21 for engaging the pulley assembly 30. The accommodating cavity 21 is provided, and the position where the pulley assembly 30 is matched with the sliding chute 22 is arranged at the bottom 212 of the accommodating cavity 21, so that the stability of matching of the swing arm 10 and the sliding rail 20 is improved.

The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
