Abstract
The utility model discloses an integral lever for weight lifting, comprising a lever body, and the lever body is provided with two retainer rings. Compared with the prior art, the utility model has the difference that the retainer rings and the lever body are combined as an entity. Two end surfaces of the lever body are flat surfaces. The utility model has the advantages of no microscopic gap between the retainer rings and the lever body, reasonable steel structure, beautiful appearance, favorable strength and high toughness.
Description
The utility model relates to physical training and the exercise equipment in the Motion Technology, is a kind ofly not have measurement mechanism, do not rely on thrust and grow or strengthen the muscle of human body or the exercise equipment in joint, and specifically, be a kind of barbell or analog.
The barbell of weight lifting competition or training, exercise usefulness, all be fixed with two back-up rings on the lever parent of its barbell, existing lever parent and back-up ring, basically be to adopt split production, and then combine that it is not only attractive in appearance but also owing to there being the microcosmic gap with process meanses such as welding or heat cooperations, after the plating, electroplating raffinate can't eliminate, and cause very easily corrosion of surface, and back-up ring comes off easily.
It is good that the purpose of this utility model provides a kind of outward appearance, the whole lever of the weight lifting that intensity is high.
Technical solution of the present utility model is: the whole lever of a kind of weight lifting, have the lever parent, and two back-up rings are arranged on the lever parent, the difference of itself and prior art is: back-up ring and lever parent are an integral body.
Both ends of the surface with back-up ring lever parent in aggregates in the utility model are burnishing surface.Be not have centre hole (centre bore) on the end face.Certainly, both ends of the surface also can be made screw etc. on demand.
Advantage of the present utility model: no microcosmic gap between back-up ring lever parent, need not sweating heat and join (interference) or other auxiliary connection measures, the structure of steel between back-up ring and lever parent is rational in infrastructure, has strengthened the toughness and the intensity of material, and good looking appearance is difficult for corrosion.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a kind of weight lifting of the present utility model with whole lever construction schematic diagram.
Fig. 2 is another kind of weight lifting of the present utility model with whole lever construction schematic diagram.
Fig. 1 has described an embodiment of the present utility model.On a steel lever parent 1, be shaped on the back-up ring 2 in aggregates with lever parent 1.Be shaped on reticulate pattern 3(as 1.5 specifications in the stage casing of lever parent 1 (promptly two back-up rings are 2)).Lever parent 1 both ends of the surface do not have centre hole.Back-up ring 2 is an integral manufacturing with lever parent 1, as adopting method manufacturings such as whole car system or hot extrusion cold extrusion, like this, with regard to having eliminated that 1 employing of back-up ring 2 and lever parent makes respectively that sweating heat is joined interference again and the microcosmic gap that can occur.Also more firm on the structure.Especially adopt hot extrusion, cold extrusion method to make, save steel, save machining period about 30%.
Fig. 2 has described another embodiment of the present utility model.It has equally lever parent 1 and with lever parent 1 back-up ring 2 in aggregates, and reticulate pattern 3 etc.What they were different with last embodiment is, all is shaped on screw 4 at two end faces of lever parent 1, so that fixing disc etc.
Claims (2)
1, the whole lever of a kind of weight lifting has the lever parent, and two back-up rings are arranged on the lever parent, it is characterized in that: back-up ring and lever parent are an integral body.
2, the whole lever of weight lifting according to claim 1 is characterized in that: with the both ends of the surface of back-up ring lever parent in aggregates be burnishing surface.
