Existing disc overall volume is comparatively large, takes up room, and when needing to fill multiple disc on bar, the space that bar is left will be few, and inconvenience is used for carrying out snatch, clean and jerk or prone position and pushes away the weight trainings such as support.More existing disc appearance and sizes differ comparatively large with international standard size, be not easy to combinationally use, compatibility is poor.

Summary of the invention

For the problems referred to above, the purpose of this utility model is to provide a kind of disc, and it has less overall volume, less taking up room and higher compatibility.

For achieving the above object, the technical scheme that the utility model proposes is: a kind of disc, comprise body, left central layer and right central layer, the excircle of described body is provided with a plurality of locating slot, the first through hole is provided with in the middle of body, isolation part between described each locating slot extends to direction, the body center of circle, and is connected to form each support member with described first through hole, and described each support member is all provided with a screw; The inner periphery on described left central layer two sides is all provided with a plurality of locating convex block, with a plurality of locating slots of described body with the use of; Described right central layer is provided with the second through hole and a plurality of counterbore, and described second through hole and the first through hole concentric are arranged, and described a plurality of counterbore is arranged on the correspondence position of described support member screw, adopts dismountable mode to be connected and fixed with described screw.

Preferably, the excircle of described body is provided with an annular protrusion, and described annular protrusion is arranged between the screw of described locating slot and described support member; Described right central layer is provided with an annular groove, is arranged on the correspondence position of described annular protrusion, cooperatively interacts fixing with this annular protrusion.

Preferably, the cross sectional shape of described locating convex block and locating slot adopts triangle, trapezoidal, circular, arc or square.

Preferably, described dismountable mode adopts screw or bolt.

Adopt technique scheme, the utility model has following beneficial effect: on body on locating slot and left central layer locating convex block with the use of, the disc of identical weight is made to have less appearance and size, saving takes up room, and this appearance and size trends towards international standard size, be convenient to combinationally use, there is higher compatibility.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figures 1 to 6, a kind of disc, comprise body 1, left central layer 2 and right central layer 3, the excircle of described body 1 is provided with a plurality of locating slot 4, the first through hole 7 is provided with in the middle of body, between described each locating slot, the isolation part of 4 extends to direction, the body center of circle, and is connected to form each support member 6 with described first through hole 7, described each support member is all provided with a screw 5; The inner periphery on described left central layer 2 two sides is all provided with a plurality of locating convex block 9, with a plurality of locating slots 4 of described body with the use of; Described right central layer 3 is provided with the second through hole 11 and a plurality of counterbore 10, described second through hole 11 and the first through hole 7 concentric are arranged, described a plurality of counterbore 10 is arranged on the correspondence position of described support member screw 5, adopts dismountable mode to be connected and fixed with described screw 5.By locating slot on body 4 and locating convex block 9 on left central layer with the use of, makes the utility model have less appearance and size, save and take up room, and this appearance and size trends towards international standard size, there is higher compatibility.Adopt in outside bolt to be connected and fixed body 1, left central layer 2 and right central layer 3 by counterbore 10 and screw 5 in addition, screw also can be adopted to be connected and fixed, but not as limit.

In the present embodiment, the excircle of described body 1 is provided with an annular protrusion 8, and described annular protrusion 8 is arranged between described locating slot 4 and the screw 5 of described support member; On described right central layer, 3 are provided with an annular groove 12, are arranged on the correspondence position of described annular protrusion 8, cooperatively interact fixing, can reduce the stressing conditions of locating slot and locating convex block with this annular protrusion 8.

In the present embodiment, the cross sectional shape of described locating convex block 9 and locating slot 4 adopts triangle, trapezoidal, circular, arc or square, not as limit, also can adopt other shape, if locating convex block and locating slot can mutually wear with the use of.

Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
