DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] As shown in Figure 1 - Figure 4 The embodiment provides a technical scheme: an auxiliary rod stretching and returning device of a sitting chest push-up training device, which comprises a main body frame 1, a support frame 2 is fixed on the main body frame 1, a push rod 3 is rotationally connected on the support frame 2, and a stretching and returning assembly 4 is arranged on the support frame 2.

[0029] As shown in Figure 2 - Figure 4As shown, the stretching return assembly 4 comprises a fixed block 41, a support plate 42 fixed on the fixed block 41, a groove 43 formed on the support plate 42, a first support seat 44 slidably connected to the support plate 42, a first support block 45 fixed on the first support seat 44, a first clamping block 46 rotatably connected to the first support block 45, a first extension spring 47 arranged on the first clamping block 46, a first connecting block 48 fixed on the first support block 45, a second support seat 49 slidably connected to the support plate 42, a second support block 410 fixed on the second support seat 49, a second clamping block 411 rotatably connected to the second support block 410, a second extension spring 412 arranged on the second clamping block 411, a second connecting block 413 fixed on the second support seat 49, a third extension spring 414 arranged on the second connecting block 413, a support rod 415 fixed on the bottom of the support plate 42, a roller 416 rotatably connected to the support rod 415, and a rope 417 arranged on the roller 416. After the user completes the chest pushing action, the push rod 3 starts to return under the action of gravity and the third extension spring 414. At this time, the first support seat 44 and the first support block 45 move downward along the direction of the support plate 42. At the same time, through the connection of the rope 417, the second support seat 49 moves in the opposite direction of the first support seat 44 on the support plate 42, so that the return action of the push rod 3 is more stable. In addition, the groove 43, the first clamping block 46 and the first extension spring 47 also play a key role. They further slow down the falling speed of the push rod 3 through mutual cooperation, effectively prevent the harm to the elbow of the user caused by the too fast falling of the push rod 3, this design not only considers the safety of training, but also fully considers the comfort of the user, makes the whole training process more smooth and natural, realizes the effective control of the return speed of the push rod 3, so as to provide a safer and more comfortable use experience, thereby solving the technical problem that the push rod 3 causes harm to the elbow of the user when it returns too fast.

[0030] The above scheme still has the problem that the push rod 3 cannot further slow down the falling speed when it falls, such as Figure 1 As shown: the fixed block 41 is fixedly connected to the support frame 2, and the first support block 45 is movably connected to the push rod 3. Since the fixed block 41 is fixed to the support frame 2, the support frame 2 can support and fix the whole stretching return assembly 4. Since the first support block 45 is movably connected to the push rod 3, the stretching return assembly 4 can slow down the falling speed of the push rod 3 and protect the elbow of the user.

[0031] As shown: Figure 2 - Figure 4As shown, one end of the first telescopic spring 47 is fixedly connected to the first support block 45, the other end of the first telescopic spring 47 is fixedly connected to the first clamping block 46, one end of the second telescopic spring 412 is fixedly connected to the second support block 410, the other end of the second telescopic spring 412 is fixedly connected to the second clamping block 411, due to the fact that one end of the first telescopic spring 47 is fixedly connected to the first support block 45, the other end of the first telescopic spring 47 is fixedly connected to the first clamping block 46, and one end of the second telescopic spring 412 is fixedly connected to the second support block 410, the other end of the second telescopic spring 412 is fixedly connected to the second clamping block 411, so that the first clamping block 46 and the second clamping block 411 are clamped in the support plate 42 through the elastic force of the first telescopic spring 47 and the second telescopic spring 412, which can further slow down the falling speed of the push rod 3, one end of the third telescopic spring 414 is fixedly connected to the fixed block 41, the other end of the third telescopic spring 414 is fixedly connected to the second connecting block 413, due to the fact that one end of the third telescopic spring 414 is fixedly connected to the fixed block 41, and the other end of the third telescopic spring 414 is fixedly connected to the second connecting block 413, through the elastic force of the third telescopic spring 414, the falling speed of the push rod 3 can be slowed down, one end of the rope 417 is fixedly connected to the first connecting block 48, the other end of the rope 417 is fixedly connected to the second support block 410, due to the fact that one end of the rope 417 is fixedly connected to the first connecting block 48, and the other end of the rope 417 is fixedly connected to the second support block 410, cooperating with the third telescopic spring 414, so that the first support seat 44 can drive the second support block 410 to move when moving, the first clamping block 46 and the second clamping block 411 are clamped in the groove 43, due to the fact that the first clamping block 46 and the second clamping block 411 are clamped in the groove 43, the first clamping block 46 and the second clamping block 411 can slow down the moving speed on the support plate 42, thereby slowing down the falling speed of the push rod 3.

[0032] Working principle:

[0033] As Figure 1 - Figure 4As shown, first, after the user completes the chest push, the return action of the push rod 3 is smoothly transitioned, which is because the first support seat 44 and the first support block 45 move downward along the direction of the support plate 42, while the second support seat 49 is connected with the first support seat 44 through the rope 417 and moves in the opposite direction on the support plate 42, thereby achieving a balance effect, effectively adjusting the gravity return of the push rod 3, avoiding the rapid return like free fall, reducing the potential safety risk, and the groove 43, the first clamping block 46 and the matched first telescopic spring 47 further buffer the downward speed of the push rod 3, forming a gradual deceleration process, which not only ensures the safety of the user during repeated training, but also greatly reduces the pressure on the elbow and other joints due to sudden weight bearing. In addition, the addition of the third telescopic spring 414 makes the whole system adaptive, and can adjust the return assist size according to the strength level of different users. This design takes into account the needs of different users, whether they are beginners or experienced fitness enthusiasts, and can perform comfortable training according to their actual situation.

[0034] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application shall still fall within the protection scope of the present application.
