Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a barbell bar of a strength equipment. Background Art

[0002] At present, the barbells of strength equipment are mostly made of square steel pipes or round steel pipes. For the sake of aesthetics, a cover needs to be added at the pipe mouth for sealing. The root of the barbell of the strength equipment is welded and fixed to the strength equipment. Since the barbell of the strength equipment is under stress for a long time, it is easy to deform under long-term use. In addition, the barbell is used frequently and needs to be taken and placed frequently. During this process, it is easy to be damaged by contact with the barbell of the strength equipment.

[0021] In the figure: 100 barbell bar body, 101 spherical end, 102 inner flange, 103 mounting hole, 104 mounting opening, 105 anti-falling ring, 106 limiting surface, 200 reinforcement plate, 300 support plate, 400 mounting arm, 401 mounting flange. DETAILED DESCRIPTION

[0022] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Example

[0023] according to Figures 1 to 4 As shown: This embodiment provides a strength equipment barbell, including a barbell body 100. The barbell body 100 adopts a circular tube with a thickness of 2 mm. The outer end of the barbell body 100 is spherical by spinning to form a spherical end 101. Since the diameter of the spherical end 101 gradually changes, it forms a guide during the barbell removal and placement process, reducing hard collision contact and making it safer to use. At the same time, the end of the barbell body 100 no longer has a pipe mouth, and does not need to be equipped with a cover for sealing. The structural strength of the spherical end 101 is much higher than that of a plastic cover, and it is not easily damaged even in the event of a collision.

[0024] In order to ensure the assembly structure of the barbell bar body 100, an inner flange 102 is provided on the edge of the pipe opening at the inner end of the barbell bar body 100. A mounting hole 103 is provided on the inner flange 102 so that it can be connected to the mounting arm 400 of the strength equipment. The mounting hole 103 is used to assemble the barbell bar body 100 with the mounting flange 401 of the mounting arm 400. Of course, since the barbell bar body 100 is subjected to a large force after the barbell plates are placed on it, the following structural improvements are made to prevent the barbell bar body 100 and its inner flange 102 from being deformed:

[0025] The outer side of the inner flange 102 is further provided with a reinforcing plate 200 welded thereto. The reinforcing plate 200 is a stainless steel plate with a thickness of 1 cm. A through hole corresponding to the mounting hole 103 is provided on the reinforcing plate 200. At the same time, the edge of the reinforcing plate 200 is aligned with the edge of the barbell bar body 100 to maintain the appearance of the barbell bar body 100. The integrated design of the reinforcing plate 200 and the barbell bar body 100 can locally strengthen the structure of the inner end surface of the barbell bar body 100 so that it will not be deformed by external forces.

[0026] At the same time, a support plate 300 is also provided inside the barbell bar body 100. The support plates 300 are provided in one group or multiple groups, which are selected according to the product design. The support plates 300 are located inside the barbell bar body 100 and are distributed vertically to meet the local reinforcement effect of the force direction of the barbell bar body 100. The edge of the support plate 300 is against the inner wall of the barbell bar body 100. The inner end of the barbell bar body 100 is provided with a mounting port 104 that matches the shape of the support plate 300 to meet the assembly and use of the support plate 300. The mounting port 104 can be located on the inner flange 102, or on the inner flange 102 and the reinforcement plate 200. The support plate 300 can be directly inserted to be assembled into place. Example

[0027] according to Figure 5 、 Figure 6 As shown: This embodiment provides a strength equipment barbell bar, which is different from the first embodiment in that:

[0028] The barbell rod body 100 also has an annular groove near its spherical end 101, and a shape-matching anti-falling ring 105 is embedded in the groove. The anti-falling ring 105 is made of rubber anti-slip material. At the same time, a limiting surface 106 is provided on the inner edge of the anti-falling ring 105. The limiting surface 106 and the surface of the barbell rod body 100 form an L-shaped step surface. In this way, when the power machine is installed at an angle and when the barbell plates are taken and placed, the barbell plates can be prevented from slipping, thereby reducing the safety risks in the use of the product.

[0029] The above description is only a preferred embodiment of the present invention. As long as the technical solution of the present invention is achieved by substantially the same means, it shall fall within the scope of protection of the present invention.
