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.
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 plate
Or disc.Common dumbbell or 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 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 plate is made of blown plastic casing and canned cement inside the shell, and PE cement dumbbell plate is relative to common
Cast iron casting dumbbell plate not only greatly reduces cost, but deficiency is: 1, big relative to cast iron casting dumbbell plate volume；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 sheet body gravitational equilibrium；6, canned hole needs to be to be easy to seal
Stifled aperture is not easy to pouring into for cement.
Summary of the invention
The utility model aim is, for some problems existing for existing dumbbell and disc, proposes a kind of novel mute
Product material cost can be greatly reduced only with respect to cast iron casting dumbbell plate in bell or disc, and relative to PE cement dumbbell
Piece is able to maintain better product appearance and smaller small product size.
In order to achieve the above purposes, the technical solution adopted by the utility model is: a kind of welding assembly formula dumbbell plate, by shell
It is constituted with the intracorporal filler of shell is seated in, which is characterized in that the shell is metal shell, and the filler is stamped compacting
Sand material.The shell is made of upper cover, lower casing and core pipe, and the lower casing includes bottom surface and is folded upward to be formed from bottom surface outer rim
Surrounding edge,
The upper cover includes top surface and bends downward the surrounding edge to be formed from top surface outer rim, the surrounding edge of the upper cover and lower casing
Peripheral part is overlapped, and the center of the upper cover and lower casing sets centre bore respectively, the top and bottom of core pipe respectively with upper cover and under
The centre bore of shell connects.The upper cover is connected with both lower casing use welding manners.
Above-mentioned dumbbell plate, as filler, is not only contributed to selection low-cost filler, reduces product material cost using sand material,
And sand shape filler stamped can be compacted, that is, be conducive to uniform filling, can be to avoid internal porosity, it again can be with when pressure is enough big
Bigger density is obtained, advantageously ensures that the balance and relatively smaller small product size of product.By shell be divided into lower casing and
Upper cover two parts provide necessary structural condition to carry out punching press compacting to filler before filling and the flanging encapsulation of filler.Effectively
Solve the problems, such as that inside formation stomata can not be handled when canned cement in PE cement dumbbell plate blown plastic casing.
The leakage of sand material can be effectively prevented in the part surrounding edge to overlap, and welding manner has stronger fastness, simultaneously
It can achieve better seal than contact envelope.
As a kind of selection, the surrounding edge of the upper cover is overlapped from outside with the surrounding edge of lower casing, the surrounding edge of lower casing and upper cover
The part that surrounding edge is overlapped is relative to its part indent below, the surrounding edge of the outer diameter of the surrounding edge of upper cover and the surrounding edge of lower casing and upper cover
The part of coincidence segment outer radius below is equal.Specifically, the segment outer radius that the surrounding edge of lower casing is overlapped with the surrounding edge of upper cover is less than
Its segment outer radius below, the thickness of the upper covers surrounding edge such as semidiameter of the two.
Further, the pad is located on the surrounding edge lower edge of upper cover and the surrounding edge of lower casing between radius transition face.
Alternatively, the surrounding edge of the upper cover is overlapped from inside with the surrounding edge of lower casing, on the surrounding edge of the upper cover
It is equal with the surrounding edge outer diameter of lower casing along the outer diameter for being equipped with a cover rim cover rim.
Further, the pad is located between the cover rim of upper cover and the upper edge of the surrounding edge of lower casing.
Further, the core pipe height is equal to or less than thickness of shell.
Further, the central hole of the upper cover sets recessed horn mouth, and the central hole of the lower casing sets fovea superior
Horn mouth.The horn mouth that the upper and lower side nozzle of the core pipe is adapted to by the horn mouth for extending out into the centre bore with upper cover and lower casing
Shape.
Dumbbell plate of the present invention is equally applicable to assembling barbell.
The utility model beneficial effect is: the material adult of dumbbell plate itself is low；The processing of shell and the compacting of sand material,
This simple and mechanical equipment of press machine is only needed to can be completed, equipment cost is low, and processing conditions is of less demanding；It is not necessarily in process
Heating, power consumption of polymer processing is low, the process waited in process without needs such as cooling, solidifications, high in machining efficiency.
