Problems solved by technology

[0005] 1. The trainer needs to remove the barbell from the barbell rack, and then carry out push training. Because the barbell rack has restrictions on the placement of the barbell, the trainer cannot train the muscles of different parts. In addition, after training for a period of time, The strength of the trainer is consumed, so it often happens that the barbell cannot be lifted again and placed on the barbell rack. At this time, the assistance of others is needed, which makes the barbell push training more cumbersome;
[0006] 2. In the prior art, when adjusting the counterweight of the barbell, the knobs at both ends of the barbell are generally rotated, and then the counterweight is increased or decreased. This method is time-consuming and cumbersome to operate. If it is not firm, it will cause the counterweight to fall accidentally, posing a safety hazard

Embodiment 1

[0038] refer to Figure 1-5 and Figure 8 , a barbell rack for convenient weight adjustment, comprising a deck board 2, the deck board 2 is placed on the ground through a base 1, one end of the deck board 2 is an arc section, and the other end is a horizontal section, and the upper surface of the deck board 2 is installed with Sponge cushion, the horizontal section upper side of lying board 2 is equipped with headrest 19.

[0039] The horizontal section of the couch 2 is equipped with a transmission box 3, and a motor 7 is installed in the transmission box 3. A sliding track 6 is installed on both sides of the couch 2 near one end of the transmission box 3, and a threaded rod 9 is installed in the sliding track 6 for rotation. And the sliding track 6 is threadedly installed with a support plate 10 through a threaded rod 9, such as Figure 4 As shown in , one end of the support plate 10 located inside the sliding track 6 has a "T" shape structure, and one end of the support p...

Embodiment 2

[0048] See details Figure 6-8 As mentioned above, in the second embodiment, the cylinder 15 is arranged on the lower side of each counterweight 13 inside the counterweight box 4. Specifically, in this embodiment, the lower side of each counterweight 13 is symmetrically provided with Two cylinders 15.

[0049] The telescoping end of the cylinder 15 is arranged upwards, and the telescoping end contacts with the bottom wall of the counterweight 13, and the bottom of the cylinder 15 is fixed with the inner wall of the counterweight box 4 by the mounting seat 18.

[0050] By arranging the cylinder 15, the counterweight 13 can be raised to the highest point, which can conveniently provide different degrees of training intensity for trainers of different strengths;

[0051] E.g:

[0052] 1. Trainers with less strength can use the cylinder 15 to Image 6 and 7 The two counterweights 13 in the shown counterweight box 4 are lifted, and the trainer only needs to bear the weight of t...
