Description

Irritate husky disc
Technical field
The present invention relates to a kind of counter weight device of body-building apparatus, the husky disc of particularly a kind of filling.
Background technology
Disc all is very important as the counter weight device in the fitness equipment all the time, and existing disc generally is entity, i.e. monoblock cast, and waste material is not attractive in appearance yet like this.And also there is fraction to be provided with over cap on the top and bottom of existing disc; But over cap can only be protected the upper and lower surfaces 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 when the blowing housing, to be set in produces simultaneously on the mould; In the middle of easy behind the filling sand, outwards heave, so the over cap that is bumped into comes off easily.In addition owing to existing over cap needs when blowing housing, be set on the mould part and could produce, so work efficiency is extremely low, the percentage of A-class goods is also low.
Summary of the invention
The objective 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.
The object of the invention is realized through following technical scheme: the husky disc of a kind of filling; Comprise hollow shell, the sidewall of housing is provided with stopper, and the housing upper surface is provided with loam cake; The lower surface of housing is provided with lower cover; The centermost place of loam cake, lower cover and housing is equipped with centre bore, and the position, limit, hole that the upper surface of housing and lower surface are positioned at centre bore a plurality of boss that all evenly distribute form concave station between every adjacent two boss; A plurality of boss and a plurality of concave station are provided with at interval; The boss of housing upper surface is corresponding with the concave station of housing lower surface, and loam cake and said covering down are equipped with the groove that matches with boss, and the sidewall sheath of loam cake and lower cover lumps together and welds through ultrasonic welding machine.
Further improvement of the present invention is: the limit, hole that the upper surface of said housing and lower surface are positioned at centre bore all is evenly distributed with three boss and three concave stations; Three boss and three concave stations are provided with at interval, and the boss of said housing upper surface is corresponding with the concave station of housing lower surface.
Further improvement of the present invention is: the upper and lower surfaces of said housing is equipped with the little groove that is used to paste the weight labeling or the upper surface and the lower surface of housing is equipped with the small boss that contains the weight numeral, and loam cake and lower cover and little groove or the corresponding position of small boss are provided with the cavity.
The present invention compared with prior art has the following advantages: irritate husky through stopper to enclosure interior, so not only saved material, and weight can be regulated; Loam cake and lower cover weld with ultrasonic welding machine after being linked on the housing, and welding back loam cake and lower cover are one; Attractive in appearance firm, disc can a plurality ofly be used, through 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, also evenly distribute a plurality of concave stations and the boss of opposite position at the centre bore back side; Relative with positive convex-concave, guarantee that assembling is consistent, guaranteed that like this disc can make up smoothly when same direction is assembled; And can be not rotary shifted, the cavity is set, like this when pasting labeling on covers; Can guarantee that labeling can not drop easily, or be equipped with the small boss that contains the weight numeral at the upper and lower surfaces of housing, the corresponding position of loam cake and lower cover and small boss is equipped with the cavity.The weight numeral can be exposed from the cavity like this, and is attractive in appearance and can not drop.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a decomposing schematic representation of the present invention;
Label among the figure: 1-housing, 2-stopper, 3-loam cake, 4-lower cover, 5-centre bore, 6-boss, 7-concave station, 8-groove, 9-cavity.
The specific embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of specific embodiment of irritating husky disc of the present invention like Fig. 1 and Fig. 2, comprise hollow shell 1, the sidewall of housing 1 is provided with stopper 2; Housing 1 upper surface is provided with loam cake 3; The lower surface of housing 1 is provided with lower cover 4, and the centermost place of loam cake 3, 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 a plurality of boss 6 that all evenly distribute; Form concave station 7 between every adjacent two boss 6; A plurality of boss 6 are provided with a plurality of concave stations 7 at interval, and the boss 6 of housing 1 upper surface is corresponding with the concave station 7 of housing 1 lower surface, is equipped with the groove 8 that matches with boss 6 on loam cake 3 and the lower cover 4; The sidewall sheath of loam cake 3 and lower cover 4 lumps together and welds through 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 all is evenly distributed with three boss 6 and 7, three boss 6 of three concave stations and three concave stations 7 settings at interval, and the boss 6 of housing 1 upper surface is corresponding with the concave station 7 of housing 1 lower surface; Upper and lower surfaces at housing 1 is equipped with the little groove that is used to paste the weight labeling; Loam cake 3 is equipped with cavity 9 with lower cover 4 and the corresponding position of little groove, or is equipped with the small boss that contains the weight numeral at the upper surface and the lower surface of housing 1, and loam cake 3 is equipped with cavity 9 with lower cover 4 and the corresponding position of small boss.
