Abstract

The invention discloses a barbell plate, which comprises a barbell plate main body, a left core plate and a right core plate, wherein counter bores are formed in the centers of the left and right sides of the barbell plate main body; the left core plate and the right core plate are embedded and pressed in the counter bores of the barbell plate main body from two sides; the face, in pressing contact with the left core plate, of the counter bores of the barbell plate main body is a first pressing contact face; a first bump is arranged on the first pressing contact face; the face, in pressing contact with the counter bores of the barbell plate main body, of the left core plate is a second pressing contact face; a first groove, corresponding to the first bump of the first convex portion, is formed in the second pressing contact face; the first bump of the first pressing contact face is matched with the first groove of the second pressing contact face, so that a first anti-falling part is formed; and a second anti-falling part, which is arranged between the right core plate and the barbell plate main body, is same with the first anti-falling part in structure. With the adoption of the technical scheme, the barbell plate can effectively solve a problem that gaps between the core plates and rubber plates are prone to form, so that the service life of the barbell plate is prolonged.

Description

A kind of disc

Technical field

The present invention relates to sports equipment field, refer in particular to a kind of disc。

Background technology

The central layer combination of current disc many employings sheet rubber and metal material, the central layer of metal material embeds sheet rubber and fastens again through securing member, owing to barbell is lifted up and down back and forth in use procedure employing, user is not be placed directly in ground when lifting and putting down but directly the power of letting out bleeds off barbell, barbell in dropping process, the easy deformation of sheet rubber, long-term accumulated outlet irreversible transformation, easily occurring gap between central layer and sheet rubber, being continuing with disc will be quickly damaged, and reduces the life-span。

Summary of the invention

The invention solves the problems that above-mentioned technical problem, it is provided that a kind of life-span is long, it is prevented that life-time service outlet sheet rubber comes off the disc damaged。

In order to solve above-mentioned technical problem, the technical scheme is that a kind of disc, including disc body, left central layer and right central layer, the center of the disc body left and right sides is equipped with counterbore, described left central layer and right central layer embed from both sides respectively and are pressed in the counterbore of disc body, it is characterized in that: the face that the counterbore of described disc body and left central layer are pressed into contact with is first be pressed into contact with face, described first is pressed into contact with face and is provided with the first projection, the face that the counterbore of described left central layer and disc body is pressed into contact with is second be pressed into contact with face, described second is pressed into contact with the first raised position that on face, correspondence first is pressed into contact with on face and is provided with the first groove, described first is pressed into contact with first projection in face and forms the first retaining member with the second the first groove fit being pressed into contact with face, the second anti-falling piece and the first anti-falling piece structure between described right central layer and disc body are identical, described left central layer and right central layer are by securing member and the fastening of disc body。

Further, the protruding dispersion adopted around at least one whole annular protrusion of disc body, annular array distribution of described first dispersion that is protruding or that be dispersed on disc body is protruding, and the first described groove is arranged in the position of corresponding first projection。

Further, the cross sectional shape of the first described projection adopts triangle, arc, square, trapezoidal or truncated cone-shaped, and the shape of the first described groove is closed with the matching form of the first projection。

Further, described left central layer and right central layer adopt ring flange shape, and there is the first through hole that can be inserted into bar centre, is provided with and the second through hole of the first through hole concentric in the middle of described disc body。

Further, described securing member adopts hexagon socket head cap screw。

Further, described disc body adopts rubber or plastics。

Adopting technical scheme, protruding and groove cooperation effectively prevents central layer and sheet rubber from producing gap problem in dropping process, it is prevented that the dislocation of central layer and sheet rubber, improves the service life of disc。

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention will be further described。

Embodiments of the invention one are as shown in Figures 1 to 3, including disc body 10, left central layer 20 and right central layer 30, the center of disc body 10 left and right sides is equipped with counterbore 11, described left central layer 20 and right central layer 30 embed from both sides respectively and are pressed in the counterbore 11 of disc body 10, described left central layer 20 and right central layer 30 adopt ring flange shape, there is the first through hole 21 that can be inserted into bar centre, it is provided with and the second through hole 12 of the first through hole 21 concentric in the middle of described disc body 10, the face that the counterbore 11 of described disc body 10 and left central layer 20 are pressed into contact with is first be pressed into contact with face 13, described first is pressed into contact with face 13 and is provided with the first projection 14, shown first protruding 14 adopts single annular protrusion, the face that the counterbore 11 of described left central layer 20 and disc body 10 is pressed into contact with is second be pressed into contact with face 22, described second is pressed into contact with the first protruding 14 positions that on face 22, correspondence first is pressed into contact with on face 13 and is provided with the first groove 23, described first is pressed into contact with first protruding 14 and second first groove 23 being pressed into contact with face 22 in face 13 and cooperatively forms the first retaining member, the second anti-falling piece and the first anti-falling piece structure between right central layer 30 and disc body 10 are identical, left central layer 20 and right central layer 30 fasten again through securing member and disc body 10, protruding and groove cooperation strengthens the connection between central layer and rubber body, effectively prevent the problem of misalignment of central layer and rubber body in dropping process, solve the problem that in the process of dropping, central layer and rubber body easily produce gap。
