[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0030] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] In physical training, it is necessary to exercise the muscles of the whole body. For the training of back muscles, since they are located on the back of the body, a special back muscle trainer is needed to assist the training. The purpose of exercising the back muscles is usually achieved by stretching from top to bottom. Existing back muscle trainers usually use a fixed frame to lift the weight, and then the user pulls to exercise the back muscles.
[0032] In the related art, the prior art requires adjustment of the position of the seat during stretching because the heights and body shapes of users are different. The prior art mainly uses an insertion rod inserted into different positioning holes to adjust the position of the seat. However, the insertion rod of the prior art device is easy to be lost alone, and when adjusting, the user needs to get up from the seat and pull out the insertion rod for adjustment, which is too cumbersome to operate.
[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a back muscle trainer. When it is needed, you only need to sit on the seat plate 14. When you need to adjust the position of the seat plate 14, you can hold the cross bar 27 with both hands and pull it upward, thereby driving the pull rod 26 to move upward. During the movement, the spring 22 is compressed until the insertion rod 25 is separated from the adjustment hole 24. At this time, you can sit on the seat plate 14 and move the position, so that the support block 13 and the bottom plate of the bracket 11 can be slid and adjusted. After adjusting to the appropriate position, release the cross bar 27. At the same time, the spring 22 rebounds and pushes the push plate 23 so that the insertion rod 25 is inserted into the inside of the adjustment hole 24, thereby fixing the support block 13 and the position of the seat plate 14 is also fixed.
[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0035] Combination Figure 1-Figure 5The embodiment of the present application provides a back muscle trainer, comprising: a bracket 11, on which a weight block 12 is arranged; a support block 13 is slidably arranged on the bracket 11; a seat plate 14 is arranged on the top of the support block 13; an adjustment component 2 is arranged on the support block 13, and the adjustment component 2 comprises: a plate body 21 is arranged on the inner side of the support block 13; a spring 22 is arranged at the bottom of the plate body 21; a push plate 23 is arranged at the bottom of the spring 22; an adjustment hole 24 is opened on the bracket 11; an insertion rod 25 is arranged at the top of the push plate 23, and the bottom passes through the support block 13 and is inserted into the adjustment hole 24; the bottom of the pull rod 26 passes through the plate body 21 and is connected to the push plate 23; one end of the cross bar 27 passes through the pull rod 26.
[0036] When in use, the user can sit on the seat plate 14, hold the upper handle with his hands and pull the weight block 12 through the rope to train the back muscles. When the next user uses it, he needs to adjust the position of the seat plate 14. He only needs to sit on the seat plate 14, then hold the cross bar 27 with both hands and pull it upward, drive the pull rod 26 to move upward, and pull the push plate 23 upward at the same time. The compression spring 22 is compressed until the insertion rod 25 is separated from the adjustment hole 24, and the seat plate 14 can be slid. Because the support block 13 is slidably connected to the bottom plate of the bracket 11, the position of the seat plate 14 can be changed. After the adjustment is completed, the cross bar 27 is released, and the spring 22 rebounds and pushes the push plate 23 downward, so that the insertion rod 25 is inserted into the inside of the adjustment hole 24, and the position of the support block 13 is fixed, and the seat plate 14 is fixed. By changing the lateral position of the seat plate 14, the angle of the upper hand grip when pulling is also changed, so the muscles at different positions of the back can be trained.
