Description

Disc

Technical field

The utility model relates to a kind of key body equipment, is meant the disc that is used to take exercise arm and waist and belly muscle especially.Disc of the present utility model comprises the payload segment that has centre bore and is positioned at least two hand-held handles of payload segment outer rim.

Background technology

Metal disc is a kind of body-building apparatus commonly used, and its common structure is to offer breach on disc core (disc core herein refers to the payload segment of disc), and in indentation, there hand-held handle is set.As Chinese utility model patent 00208217.9 disclosed disc, it comprises the disc core of being made by metal material that is symmetric shape and is positioned at the outer non metallic decorative layer of disc core, at the center of disc one through hole is arranged, the position that is positioned at two symmetries on disc respectively is provided with a V-shaped breach to disc core outer rim, and described two V-notch places respectively are equipped with one and are used for for the handle of tempering user's grasping.Mostly be between handle of being put in the prior art and handle fixing hole with screw thread or riveted and fixed, perhaps have telescopic special construction, the special construction that utilizes handle end when cooperating is installed is made the interior formation of mating holes on its end embedding disc fixing in handle end.There is following deficiency in prior art:

1, because fit structure between the fixing hole on disc handle and the disc core in the prior art, it is shorter that handle and disc payload segment combine length, and easily to make the junction of disc core and handle be a critical section, destroys herein easily.More be easy to generate this problem for disc with forging type production.

2,, make in the prior art disc handle relative with the combination between the disc core not too reliable owing to aforesaid reason.

3, no matter be to use thread connection in the prior art, still with riveted joint, its structure is comparatively complicated, and manufacturing cost is higher.And adopting the flexible structure of special band when the end of handle, it makes difficulty especially.

Summary of the invention

The utility model provides a kind of novel disc that overcomes the prior art deficiency, between the payload segment of its handle and disc to combine length longer, in conjunction with reliable, the integrated structure between handle and disc payload segment is fairly simple, and manufacture difficulty is lower.

The outer rim of payload segment of the present utility model is fixed with the ring of metal, and the breach of indent is arranged at two symmetric position places of payload segment outer rim at least, and presents one section metallocycle in each indent indentation, there of payload segment, forms the hand-held handle of disc.

In the utility model, on the metallocycle part of the indent indentation, there of the payload segment of disc, be coated with one deck flexible material, form hand-held handle.

In the utility model, on the payload segment of disc, be provided with the breach of the indent of two pairs of symmetric arrangement, and the breach of two pairs of indents is mutually orthogonal layout.

Among the embodiment of the present utility model, its payload segment is made up of the chip of two symmetries, the outer rim place of each chip is provided with the arc groove that matches with metallocycle, the corresponding fixing hole of arranging is arranged on each chip, and two chips are fixed together with the bolt that passes fixing hole, be arranged in the metallocycle of two arc grooves on the chip simultaneously owing to be to place arc groove, and be fixed on the edge of two chips.

In another embodiment of the present utility model, be the relevant position that when disc is cast, metallocycle is placed the disc sandbox, the ring-like thing of metal is embedded the centre at disc load body edge with forging type.

Because handle of the present utility model is the part of the complete metallocycle that exposes on disc, and metallocycle is to be embedded on the payload segment of disc by casting, or be fixed in the set arc groove of disc two chip edges by two chips, so handle of the present utility model is more more reliable than prior art with combining of disc.By after the detailed explanation chatted can find out that also the utility model structure is simple relatively, its manufacturing cost is also lower.

Description of drawings

Fig. 1 is a front view of the present utility model.Fig. 2 is the left view of Fig. 1.Fig. 3 is the cutaway view of an embodiment of the present utility model.Fig. 4 is the cross-sectional schematic of another embodiment of the utility model.

The specific embodiment

Explain orally the utility model below in conjunction with drawings and Examples.

See Fig. 1, in the utility model, 1 for having the payload segment of centre bore, and the outer rim place fixing metal ring 31, disc payload segment 1 have the breach 2 of the indent of four symmetrical distributions, and each breach is divided into 90 degree mutually, so forms symmetric arrangement.Concane gap 2 places present one section metallocycle 3 in each of payload segment 1, are coated with nonmetal flexible materials 4 such as plastics or rubber in the outside of this section metallocycle, form the hand-held handle of disc.Also can be about concrete structure of the present utility model referring to Fig. 2, Fig. 2 is the left view of Fig. 1.If when the interior concane gap 2 of two symmetrical distributions only is set on the disc of the present utility model, can form another embodiment of the present utility model.

The cross-sectional schematic of the embodiment of the utility model that Fig. 3 is given.This figure analyse and observe the position for the A-A of Fig. 1 to rotation.Present embodiment is with forging type metallocycle 3 to be embedded in the payload segment 1 of disc.By Fig. 3 the latter half as seen, the edge of the payload segment 1 non-breach of its disc is embedded with metallocycle 3, be when disc is cast, will encircle 3 to put into the relevant position that casts sandbox during specific implementation, can ring 3 firm being fixed in wherein after the melt metal cooling in casting.

Fig. 4 is another embodiment of the present utility model.This figure analyse and observe the position for the B-B of Fig. 1 to.In the present embodiment, the payload segment 1 of disc is that chip 5 and 6 by two symmetries constitutes.Respectively there is arc groove 7 at the edge of chip 5 and 6 non-indentation, there, also is useful on fixing hole 8 on chip 5 and 6 respectively.When assembling, earlier metallocycle 3 is positioned in the arc groove on the chip 5, again with chip 6 " lid " on chip 5, penetrate hole 7 on two chips with bolt 9, screw nut 10 again with two chip fixations.Hole 8 on the chip in the present embodiment is screw also, and counter sink then can be made in the hole 8 on another chip, with sunk screw two chips is fixed when assembling, can make the surface of disc comparatively smooth like this.Other is noted that when adopting present embodiment, arc groove 7 should be suitably less than the diameter of becket 3, can guarantee like this ring 3 at groove 7 by secure fixation, avoided the fixing back of assembling to encircle 3 rotation phenomenon around the disc centre bore.

Those of ordinary skill in the art by structural representation that accompanying drawing is provided and above explanation as can be known, Structure of the present utility model is more simple, and its production cost is relatively low, and wherein a part of as handle Metallocycle and the combination between the disc payload segment is more more firm than prior art, reliable.
