Abstract
The invention discloses a sand filled dumbbell piece comprising a hollow shell filled with such counterweights as sand, concrete or iron sand, wherein a stopper is arranged on the side wall of the shell, an upper cover is arranged on the upper surface of the shell, a lower cover is arranged on the lower surface of the shell, central holes are arranged at the centers of the upper cover, the lower cover and the shell, a plurality of bosses are uniformly distributed at positions located on the edges of the central holes of the upper surface and the lower surface of the shell, a depression is formed between each two adjacent bosses, the plurality of bosses and the plurality of depressions are arranged at intervals, the bosses on the upper surface of the shell are corresponding to the bosses on the lower surface of the shell, grooves matched with the bosses are arranged on the upper cover and the lower cover, and the side walls of the upper cover and the lower cover are sleeved together and are welded through an ultrasonic welding machine. The sand filled dumbbell piece disclosed by the invention can be used for effectively protecting the shell, the shell and the upper and the lover covers can be processed with various different colors, so that the outlines are beautiful, the assembled dumbbell pieces cannot move towards each other, and the sand filled dumbbell piece has the advantage of simple structure.
Description
Technical field
The present invention relates to a kind of counter weight device of body-building apparatus, particularly the husky disc of a kind of filling.
Background technology
Disc, as the counter weight device in fitness equipment, is all very important all the time, and existing disc is generally entity, i.e. material is wasted in monoblock cast like this, also not attractive in appearance.And on the top and bottom of existing disc, also there is fraction to be provided with over cap; but over cap can only be protected the upper and lower surface of disc; and can not protect the outer circumference surface of disc; the outer circumference surface of disc is easy to wearing and tearing like this; and because existing over cap is to use moulding to be set on mould and to produce when blowing housing simultaneously; in the middle of easy after filling with sand, outwards heave, the over cap being therefore bumped into easily comes off.In addition because existing over cap need be set in piece by piece on mould and could produce when blowing housing, so work efficiency is extremely low, the percentage of A-class goods is also low.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of and can effectively protect housing, the husky disc of filling simple in structure.
Object of the present invention is achieved through the following technical solutions: the husky disc of a kind of filling, comprise hollow shell, the sidewall of housing is provided with stopper, housing upper surface is provided with upper cover, the lower surface of housing is provided with lower cover, upper cover, the place, center of lower cover and housing is equipped with centre bore, the position, limit, hole that the upper surface of housing and lower surface are positioned at centre bore is all uniformly distributed a plurality of boss, between every adjacent two boss, form concave station, a plurality of boss and a plurality of concave stations interval arrange, the boss of housing upper surface is corresponding with the concave station of housing lower surface, upper cover and described under cover and be equipped with the groove matching with boss, the sidewall sheath of upper cover and lower cover is combined and welds by ultrasonic welding machine.
Further improvement of the present invention is: the limit, hole that the upper surface of described housing and lower surface are positioned at centre bore is all evenly distributed with three boss and three concave stations, three boss and three concave station intervals arrange, and the boss of described housing upper surface is corresponding with the concave station of housing lower surface.
Further improvement of the present invention is: the upper and lower surface of described housing is equipped with for pasting the little groove of weight labeling or the upper surface of housing and lower surface and is equipped with the small boss that contains weight numeral, and the upper cover position corresponding with little groove or small boss with lower cover is provided with cavity.
The present invention compared with prior art has the following advantages: by stopper, to enclosure interior, fill with husky, so not only saved material, and weight can regulate, after upper cover and lower cover are linked on housing, with ultrasonic welding machine, weld, after welding, upper cover and lower cover are integrated, attractive in appearance firm, disc can a plurality ofly be used in conjunction with, by the equally distributed boss in limit, hole and the concave station of each centre bore, boss and concave station mutual dislocation, the size of boss and concave station matches, at the centre bore back side, opposite position is also uniformly distributed a plurality of concave stations and boss, relative with positive convex-concave, guarantee that assembling is consistent, guaranteed that like this disc can combine smoothly when same direction assembling, and can be not rotary shifted, cavity is set in upper and lower covers, like this when pasting labeling, can guarantee that labeling can not drop easily, or be equipped with in the upper and lower surface of housing the small boss that contains weight numeral, upper cover is equipped with cavity with the lower cover position corresponding with small boss.Weight numeral can be exposed from cavity like this, attractive in appearance and can not drop.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposing schematic representation of the present invention;
Number in the figure: 1-housing, 2-stopper, 3-upper cover, 4-lower cover, 5-centre bore, 6-boss, 7-concave station, 8-groove, 9-cavity.
the specific embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 and Fig. 2 show a kind of specific embodiment of filling with husky disc of the present invention, comprise hollow shell 1, the sidewall of housing 1 is provided with stopper 2, housing 1 upper surface is provided with upper cover 3, the lower surface of housing 1 is provided with lower cover 4, upper cover 3, the place, center of lower cover 4 and housing 1 is equipped with centre bore 5, the position, limit, hole that the upper surface of housing 1 and lower surface are positioned at centre bore 5 is all uniformly distributed a plurality of boss 6, between every adjacent two boss 6, form concave station 7, a plurality of boss 6 and a plurality of concave station 7 intervals arrange, the boss 6 of housing 1 upper surface is corresponding with the concave station 7 of housing 1 lower surface, on upper cover 3 and lower cover 4, be equipped with the groove 8 matching with boss 6, the sidewall sheath of upper cover 3 and lower cover 4 is combined and welds by ultrasonic welding machine, the limit, hole that the upper surface of the preferred housing 1 of the present invention and lower surface are positioned at centre bore 5 is all evenly distributed with three boss 6 and three concave stations 7, three boss 6 and three concave station 7 intervals arrange, the boss 6 of housing 1 upper surface is corresponding with the concave station 7 of housing 1 lower surface, upper and lower surface at housing 1 is equipped with for pasting the little groove of weight labeling, upper cover 3 position corresponding with little groove with lower cover 4 is equipped with cavity 9, or be equipped with at upper surface and the lower surface of housing 1 small boss that contains weight numeral, upper cover 3 is equipped with cavity 9 with lower cover 4 position corresponding with small boss.
