Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment:

as shown in fig. 1-4, a dorsal muscle trainer for physical training comprises a frame 1, a swing rod 2 and a swing arm 3, wherein a supporting plate 11 is arranged at the top of the frame 1, a guide rod 12 is fixedly arranged at the bottom of the supporting plate 11, the guide rod 12 is arranged on the frame 1 in a penetrating manner, the guide rod 12 is in sliding fit with the frame 1, a first air cylinder 13 is arranged at the top of the frame 1, the first air cylinder 13 is connected with the supporting plate 11 for driving, a supporting rod 14 is fixedly arranged at the top of the supporting plate 11, the swing rod 2 is hinged at the top of the supporting rod 14, a balancing weight 21 is fixedly arranged at the tail of the swing rod 2, a spring rod 22 is fixedly arranged at one side of the tail of the swing rod 14 corresponding to the swing rod 2, a rod support 23 is fixedly arranged at the front end of the spring rod 22, the rod support 23 is in clamping fit with the swing rod 2, the swing arm 3 is hinged at, the outer side of the lug 32 is hinged with a connecting rod 33, and the other end of the connecting rod 33 is hinged with the swing arm 3 on the corresponding side.

Preferably, the frame 1 is provided with a training seat 15 for a trainer to sit on for training.
