Embodiment 1

[0030] Example 1: Please refer to Figure 1-4 , this embodiment discloses a slow-release arm bar, which includes a handle 1, a spring 2, and a hollow handle 2 5. A cross bar 15 is arranged inside the handle 2 5, and the cross bar 15 rotates around its own axis. The two ends of the rod 15 are rotationally connected with the inner wall of the handle 2 5 through bearings or draw-in slots, the cross bar 15 is fixedly connected with the inner end of the scroll spring 9, and the outer end of the scroll spring 9 is fixedly connected with the inner wall of the handle 2 5 .

[0031] The present embodiment also comprises connecting rope 3, elastic part 8, rotating plate 13 and connecting piece, and handle two 5 outsides are provided with perforation near the position of spring 2, and one end of connecting rope 3 is wound on cross bar 15, and connecting rope 3 The other end passes through the perforation and is connected with handle one 1 .

[0032] One end of rotating plate 13 is conn...

Embodiment 2

[0040] Embodiment two: if image 3 As shown, this embodiment discloses a slow-release arm bar, the structure of which is roughly the same as that of Embodiment 1, the difference is that this embodiment also includes a buckle bar 14 located between the rotating plate 13 and the cross bar 15 , The buckle bar 14 is fixed on the inner wall of the handle two 5, and a hole is formed between the buckle bar 14 and the inner wall of the handle two 5, and the connecting rope 3 passes through the hole.

[0041] The working process and principle of this embodiment are: the buckle 14 presses the connecting rope 3 on the inner wall of the handle 2 5 to ensure that when the connecting rope 3 is pulled out from the handle 2 5, the contact between the rotating plate 13 and the connecting rope 3 Sufficient, and the frictional force when connecting rope 3 is tightened up is less than the frictional force when unwinding rope.

Embodiment 3

[0042] Embodiment three: as figure 1 , figure 2 and image 3 As shown, this embodiment discloses a slow-release arm force rod, the structure of which is roughly the same as that of Embodiment 1, the difference is that this embodiment also includes a pull cord 16 and a handle 2 on the side away from the spring 2. Draw ring 17, one end of stay cord 16 is fixedly connected with draw ring 17, and the other end of stay cord 16 runs through handle 2 5 and is fixedly connected with the outside of rotating plate 13.

[0043] The working process and principle of this embodiment are: when the connecting rope 3 is pulled out from the inside of the handle 25, the friction between the rotating plate 13 and the connecting rope 3 is too large, causing the spring 2 to fail to return to the natural state. Ring 17 pulls stay cord 16, and stay cord 16 pulls rotating plate 13 to rotate, and the frictional force between rotating plate 13 and connecting rope 3 becomes smaller, and spring 2 returns...

Abstract

The invention discloses a slow-release arm strength rod, which comprises a handle 1, a spring and a handle 2. A cross bar is arranged inside the handle 2. The cross bar rotates around its own axis, and the inner end of the cross bar is fixedly connected with the scroll spring. , the outer end of the volute spring is fixedly connected to the inner wall of the handle 2, and also includes a connecting rope, an elastic piece, a rotating plate and a connecting piece. There is a perforation on the outer side of the handle 2 near the spring, and one end of the connecting rope is wound on the cross bar , the other end of the connecting rope passes through the hole and is connected to the handle one, one end of the rotating plate is connected to the inner wall of the second handle through the connecting piece, the other end of the rotating plate is inclined to the cross bar and contacts the connecting rope, the rotating plate The middle part of the elastic part is fixedly connected with one end of the elastic part, and the other end of the elastic part is fixedly connected with the inner wall of the handle 2, and the elastic part presses the rotating plate to the connecting rope; the slow-release arm rod increases the rebound time and slows down the The elastic release after the slow-release arm bar is bent ensures the safety of the user.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a slow-release arm bar. Background technique [0002] The arm strength rod is used to exercise the body. When using it, hold the grips at both ends of the arm strength rod with both hands, so that the strength can be concentrated on both hands, and bend the arm strength rod hard to make the arm strength rod bend. Do your best to make the arm strength rod bend to the greatest extent. Then release and repeat the above action. [0003] After the arm strength rod is bent, it needs to be controlled so that it can be reset slowly. If there is a loss of force or an operation error, the arm strength rod will rebound quickly, and it is easy to injure people or objects. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a slow-release arm force bar, which increases the rebound time and ...
