Description
Technical field
The utility model belongs to the required field of human lives, be related to not against thrust and promote or enhance human body muscle or
The exercising device of growing article refers in particular to dumbbell or barbell.
Background technique
Dumbbell and barbell are that two kinds of common fitness training instruments are favourably welcome because its is easy to use.Dumbbell and barbell structure
It is essentially identical, one or more plate-likes are assembled at rod-like members both ends or spherical weight is formed, and plate-like weight is commonly called as dumbbell disk
Or barbell disc.Common dumbbell or barbell disc is mostly iron castings, some fill lead material in iron castings to increase weight and reduce body
Product.To prevent dumbbell or barbell from colliding with when in use other articles, one layer of preventing rubber layer generally is coated on its surface.Cast iron casting is mute
Bell and barbell disc one side material cost are high.On the other hand, casting is related to hot conditions, needs to build the equipment such as smelting furnace, equipment
It is at high cost, and professional is needed to operate.
PE cement dumbbell disk is made of blown plastic casing and canned cement inside the shell, and PE cement dumbbell disk is relative to common
Cast iron casting dumbbell disk not only greatly reduces cost, but deficiency is: 1, big relative to cast iron casting dumbbell disk body product；2, blow moulding machine cost
Still higher；3, blown plastic casing easily deforms during being cooled and shaped, and influences product appearance；4, the canned hole of shell influences to produce
Product appearance；5, stomata easy to form during cement is canned leads to the reduction of disk body gravitational equilibrium.
Summary of the invention
The utility model aim is, for some problems existing for existing dumbbell and barbell disc, proposes a kind of novel mute
Bell or barbell disc not only can be effectively reduced product material cost, but also be able to maintain preferably relative to PE cement dumbbell disk
