Description
Technical field
The utility model relates to a kind of counter weight device of body-building apparatus, particularly the husky disc of 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. material is wasted in monoblock cast like this, and is also not attractive in appearance.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 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 the mould when the blowing housing to produce simultaneously; outwards heave in the middle of easy after filling with sand, the over cap that therefore is bumped into comes off easily.In addition owing to existing over cap needs be set in piece by piece on the mould when blowing housing and could produce, so work efficiency is extremely low, the percentage of A-class goods is also low.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of and can effectively protect housing, the husky disc of filling simple in structure.
The purpose of this utility model 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, the housing upper surface is provided with loam cake, the lower surface of housing is provided with lower cover, loam cake, 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 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 stations interval arrange, the boss of housing upper surface is corresponding with the concave station of housing lower surface, loam cake and described lower covering are equipped with the groove that matches with boss, and the sidewall sheath of loam cake and lower cover is combined and welds by ultrasonic welding machine.
Further improvement of the utility model is: the limit, hole that the upper surface of described 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 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 utility model is: the upper and lower surface of described housing is equipped with for the little groove of pasting the weight labeling or upper surface and the lower surface of housing and is equipped with the small boss that contains the weight numeral, and loam cake is provided with the cavity with the lower cover position corresponding with little groove or small boss.
The utility model compared with prior art has the following advantages: fill with husky by stopper to enclosure interior, so not only saved material, and weight can be regulated, after loam cake and lower cover are linked on the housing, weld with ultrasonic welding machine, loam cake and lower cover are integrated after the welding, attractive in appearance firm, disc can a plurality ofly be used, 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 centre bore back side opposite position also evenly distribute a plurality of concave stations and boss, relative with positive convex-concave, guarantee that assembling is consistent, guaranteed that like this disc can make up smoothly when same direction assembling, and can be not rotary shifted, in upper and lower covers the cavity is set, when pasting labeling, can guarantees that labeling can not drop easily like this, or being equipped with the small boss that contains the weight numeral in the upper and lower surface of housing, loam cake is equipped with the cavity with the lower cover position corresponding with small boss.The weight numeral can be exposed from the cavity like this, and is attractive in appearance and can not drop.
