Description

A kind of dumbbell

The utility model relates to the dumbbell that a kind of physical training is used, it comprise two bell heads and be fixedly linked in two on the bell head handle and the bell head outside with handle outside the plastics or rubber or other metal that are wrapped up.

Existing dumbbell adopts the metal manufacturing more, also can be with stone or concrete manufacturing, but because its good looking appearance of metallic article, manufacturing process is simple relatively again, so mostly existing dumbbell is to make with metal.Bell head of being produced as available technology adopting metal cutting or casting method etc. and the handle that connects two bell heads are metal.For realizing that dumbbell has different weight, be the dumbbell that the size of the dumbbell size by the control manufacturing is produced Different Weight in the prior art.The metal use amount of prior art dumbbell is bigger, and the size of used amount of metal is main just for making its requirement that can satisfy constant weight, not other meaning.Because the metal use amount is excessive, make the dumbbell production cost too high, also there is the metals resources improper use and the wasting phenomenon that causes from certain angle simultaneously.China's utility model patent 99257275.4 and 00203549.9 disclosed two kinds of dumbbells that adopt tubing as the dumbbell handle, its objective is the dumbbell handle and the issuable defective of bell head part that overcome Foundry Production, but its bell head part remains integrally-built, still has the too much deficiency of metal use amount in the prior art.

The utility model provides the relative prior art of a kind of cost lower, though the dumbbell that adopts the metal material manufacturing but can the least possible use metal, but this dumbbell still keeps the advantage of metallic article good looking appearance, and can make its requirement of satisfying weight own, can reduce metal use amount of the prior art.The utility model can overcome the metals resources improper use and the wasting phenomenon that causes to a certain extent, and can lower production cost.

The utility model purpose realizes by following technique measures: roll and be welded into different several piece housings with sheet metal and interfix to connect and form.The cross sectional shape of described these housings has nothing in common with each other, and a piece housing and two housings as the bell head as handle should be arranged in the housing of a dumbbell at least.Wherein the housing cross sectional shape of bell head part can be circular, also can be polygon, as hexagon or octagon, or the like.These housings are coupled to each other together with welding manner, form dumbbell, and the housing parts that forms each bell head part has an end face that is used to seal at least, makes the inner chamber body that at least one sealing is arranged in the housing of the bell head that forms, and is placed with the mass as counterweight in described inner chamber body.The mass of placing in bell head inner chamber body in the utility model can be broken sandstone, or concrete, or cork.Certainly, the mass of placing in the bell head inner chamber body also can be as metal materials such as steel or cast iron or aluminium or lead, and can be with the cutting metal of discarding when adopting metal material as the mass of inner chamber body, as metal fragment etc.

In the utility model, each the bell head capsule body that is rolled into by sheet metal can respectively be provided with an end face that is used to seal at its outboard end with the handle portion housing end that links.

The utility model is owing to be to roll into shelly with sheet metal outside having adopted, and it is inner for placing the cavity structure of mass, can keep good, the easy production of metallic article outward appearance like this, be not easy advantages such as distortion, and can obviously reduce the use amount of metal, make into manufacturing cost and reduce greatly.Extremely the object of cheapness is as the mass of dumbbell because the utility model is with broken sandstone or concrete etc., so it can save metal material, a kind of " environment-friendly type " product of can yet be regarded as.When adopting each bell head capsule body, the utility model links end when respectively being provided with the structure of an end face that is used to seal at its outboard end with the handle portion housing, can make each bell head be divided into two not connected closed inner chambers, this with regard to guaranteed when its built-in mass be that easy " flowing " object of broken sandstone class is restricted in the corresponding bell head in use, thereby avoided the bell head of inner matter " flow direction " dumbbell one side in use, cause weight to concentrate on a side bell head, and the sensation to user's discomfort that produces.

Description of drawings: given among the figure is a kind of embodiment of the present utility model.Accompanying drawing of the present utility model is a half sectional view, and its first half has showed relation and the corresponding construction between bell head and handle, and its latter half has showed outer shape of the present utility model.

In the drawings: 1 is the dumbbell head partial shell that rolls and be welded into sheet metal, 4 is the handle housing that rolls and be welded into metal, 5 for being wrapped in plastics or the rubber layer outside the handle housing, 6 for to be wrapped in external plastics of bell head capsule or rubber layer, and 3 is the cavitys that are used to place mass in the bell head capsule body.More clear for drawing is represented in the accompanying drawings, its built-in mass does not draw in the cavity 3.The end face 2 of the sealing that useful welding forms at the outboard end place of each bell head has another end face that is used to seal 7 in addition on each bell head capsule body and with the handle housing place of linking.Obviously, at housing 1 and two Closed Ends 2 and cavity 3 that is not conducted with another bell head of 7 formation of each bell head, wherein can insert broken sandstone, perhaps concrete, perhaps cork (when dumbbell is little weight), the perhaps mass of metal material is so that dumbbell satisfies its important asking.Simultaneously because the effect of end face 7 makes the built-in mass that can " flow " can " race " not arrive opposite side when dumbbell tilts.

The bell head capsule body in the utility model and the cross sectional shape difference of handle housing, wherein the cross section of bell head part can be circular, also can be polygonal, as quadrangle, or hexagon, or octagon ..., given in the accompanying drawing is octagonal bell head; And the cross section of handle housing 4 generally is circular, but its vertical section can be straight (being that handle is cylindrical), also can be curved, handle promptly becomes cydariform like this, its handle housing is cylindrical in the structure that accompanying drawing provides, but the plastics of its outer wrapping or rubber layer are curved, form the handle of drum type.Other it should be noted that handle also can wrap up non-its metal material outward, to satisfy different product decoration needs.

Bell head part of the present utility model is welded after can adopting the moulding of punching stretch mode again, adopt the housing of welding manner and handle portion to mutually combine again, be fixed in the Closed End 7 of outboard end after in cavity 3, inserting mass again with welding or riveted joint mode, again whole dumbbell is carried out decorative appearance at last and handle, parcel is positioned at the plastics of outside or the decorative layer of rubber or metal.When the utility model is the heavier dumbbell of weight, can reinforcement be set at point of attachment of handle and bell head etc.
