Abstract

The utility model discloses a metal weight balance plate of a barbell. The utility model provides the exterior of the metal cheese-structural plate being covered by a layer of rubber or plastic. Exactly speaking, the utility model provides the exterior of the outer annulus of the metal plates being covered with a layer of rubber or plastic. Furthermore, the width of the rubber ring or plastic ring is slightly larger than that of the metal part of the plate.

Description

Disc

Technical field

The utility model relates to a kind of sports equipment, is a kind of metal disc as the barbell counterweight exactly.

Background technology

The disc that is used for the barbell counterweight is the modal sports equipment of weight loading exercise.Disc is that metal is processed into the cheese structure that has centre bore in the prior art.Because the hard ground of in use percussion on ground being destroyed easily the athletic ground, metal disc surface.Secondly, assembling or when mobile, disc and ground can produce noise, even in use also can send the noise that makes the people unhappy because of the interaction of metal between disc.In using in addition between disc metal interaction the decorative layer on disc surface is damaged, can make the disc outward appearance become bad on the one hand, also can cause disc corrosion, destruction on the other hand.

Summary of the invention

The utility model provides a kind of can overcome the prior art deficiency, can effectively reduce the noise that the disc interphase interaction produces, and the noise when disc and ground effects, simultaneously can farthest reduce the impact failure of disc, and cause the disc of the destruction of disc surface decoration layer can reduce because of the mutual effect of disc intermetallic phase the time ground.

The utility model is at disc outer wrapping one deck rubber or plastics with metal cheese structure.

In embodiment of the present utility model excircle outer wrapping one deck rubber or plastics in metal disc part.More exactly, have the annular groove of an indent at least at the excircle of the metal of disc part, it is embedded with the rubber ring or the plastic hoop of band evagination, and rubber ring or plastic hoop are positioned at the metal part that the outer partial width of disc annular groove is a bit larger tham disc; Perhaps have the annular protrusion of an evagination at least at the metal excircle partly of disc, the annular protrusion bag is embedded in the groove set on rubber ring or the plastic hoop inner surface, and the width of rubber ring or plastic hoop is a bit larger tham the width of the metal part of disc.

Because the utility model outer " parcel " has one deck rubber or plastics, effect by rubber or plastics when two discs interact can not directly act on the metal between disc, both can reduce the destruction of the direct contact action of metal between disc to its surface, alleviate disc to the destruction that the rigid shock on ground causes, the noise that can lower the disc intermetallic again or produce when contacting with ground.

When the utility model only adopts when the disc metal part is divided on the excircle annular gum cover of bag or plastic sheath structure, remove and to avoid metal between disc directly to do the destruction that the time spent causes the rigid shock on ground the destruction on its surface and disc, lower between disc or with ground between the noise of generation when contact, can also reduce the consumption of rubber or plastics, simplified manufacturing technique reduces production costs.

Description of drawings: accompanying drawing is the generalized section of an embodiment of the utility model.

The specific embodiment

What accompanying drawing was given is most preferred embodiment of the present utility model.Explain orally the utility model below in conjunction with embodiment.

Among the figure, 1 is the metal part of disc, and centre bit is equipped with the hole of matching with bar 2,3 for being located at the rubber ring on metal disc 1 excircle thereon.Can know by figure and to see that the excircle of disc metal part 1 is provided with the annular groove 4 of an indent.Can also know by figure and to see that the inner periphery of rubber ring 3 is provided with the projection 5 in the annular groove 4 of the set indent of the excircle that can embed disc metal part 1.That both are combined is more reliable for set spill annular groove 4 and projection 5 on disc 1 and the rubber ring 3.

In practical structure, the width of rubber ring 3 should be slightly larger than the width of disc metal part 1, the inventor think rubber ring 3 width than the width of the metal part 1 of disc big approximately 2 to 10 millimeters for good.Between two discs, contact like this, perhaps disc is when the horizontal state contacts with ground, rubber ring 3 on it can separate two discs, make and do not produce actual contact between the two, also just can not be because of collision, the friction that causes disc that contact between intermetallic or metal and ground, also reduced simultaneously between disc or with ground between the noise that produces when contacting.Disc is loaded in the use on the barbell, be to contact with ground when placing down the weight by the disc excircle part, and divide in the metal part of disc in the present embodiment one deck rubber is arranged on the excircle, it can cushion the impulsive force between disc and ground when barbell puts down, the noise of generation in the time of simultaneously reducing disc and contact with ground.At disc metal excircle the friction that rubber or plastics can also strengthen user's hand and disc is set in addition, this also can make things convenient for the installation and removal operation of disc.

Another embodiment of the present utility model is with system one cambered outwards annular protrusion on the excircle of the metal part of disc, and this annular protrusion bag is embedded in the groove set on the inner surface of rubber ring, equally, the width of the rubber ring in this example also should be a bit larger tham the width of the metal part of disc.As establish a plurality of spill annular grooves on disc, the corresponding a plurality of projectioies that match with it of establishing on rubber ring are perhaps established a plurality of projectioies, and establish a plurality of spill annular grooves on the rubber rings that is mated on disc, promptly form other different embodiment of the utility model.Though do not provide corresponding accompanying drawing in this manual about these embodiment, by the accompanying drawing that reference provides, those of ordinary skill in the art is the detail that can draw dependency structure.

Above its outer wrapping layer of the utility model embodiment is a rubber, but the utility model is not limited to the restriction of embodiment, and its outer wrapping layer also can adopt plastics.

Claims

1, makes the disc that is cheese that has centre bore with metal, it is characterized in that parcel one deck rubber or plastics on the disc outer surface.

2, disc according to claim 1 is characterized in that at disc excircle outer wrapping one deck rubber or plastics.

3, disc according to claim 2, it is characterized in that the excircle of the metal part of disc has the annular groove of an indent at least, it is embedded with the rubber ring or the plastic hoop of band evagination, and rubber ring or plastic hoop are positioned at the metal part that the outer partial width of disc annular groove is a bit larger tham disc.

4, disc according to claim 2 is characterized in that the excircle of the metal part of disc has the annular protrusion of an evagination at least, and this annular protrusion bag is embedded in the groove set on rubber ring or the plastic hoop inner surface.
