Abstract
The utility model provides a dumbbell piece structure, it includes dumbbell piece body and the filler of packing in dumbbell piece body, its characterized in that: the dumbbell piece body comprises a box body, an upper cover covered on the box body and an annular cylinder which is arranged between the box body and the upper cover, connected with the box body and the upper cover together and used for connecting a handle. The box body and the upper cover are manufactured by adopting punch forming, the forming effect is better, the appearance is more attractive, the concave design of the box body is more convenient for the assembly of the upper cover, the production efficiency is increased, the two ends of the annular cylinder are respectively folded outwards after being punched, so that the box body and the upper cover are tightly buckled together, the production and assembly efficiency is greatly accelerated, the previous welding link is omitted, and the production cost is saved.
Description
Technical Field
The invention relates to fitness equipment, in particular to a dumbbell sheet structure.
Background
With the improvement of living standard of people, people also have stronger concept of body building, but due to the limitation of shortage of urban body building places, it is quite difficult to find better exercise places. More and more people choose to buy the fitness equipment to do exercise at their own home, the dumbbell is a practical training equipment, and the dumbbell is popular among fitness enthusiasts due to small volume and weight which can be selected according to the actual situation. The dumbbell divide into cast iron dumbbell and irritates husky dumbbell, the cast iron dumbbell is cast by iron and is formed cost of manufacture big, and the price is high, irritate husky dumbbell low in manufacturing cost, but its manufacturing process is loaded down with trivial details, need pack into the dumbbell with sand, seal it up, traditional sealing process is in the same place in the welding after combining through the box body symmetry that will two upper and lower structures the same, it is smooth to polish welded edge after the welding is good, in order to prevent that the box body from moving all around when the welding, often need put into the box body on the anchor clamps fixed, production efficiency is very low.
Disclosure of Invention
The invention aims to provide a dumbbell sheet structure which is simple in structure and convenient to produce and process.
The invention aims to realize the dumbbell sheet structure through the following technical scheme, and the dumbbell sheet structure comprises a dumbbell sheet body and filler filled in the dumbbell sheet body, and is characterized in that: the dumbbell piece body consists of a box body, an upper cover covered on the box body and an annular cylinder which is arranged between the box body and the upper cover and connected with the box body and the upper cover together for connecting a handle, the middle of the box body is provided with a first through hole, the middle of the upper cover is provided with a second through hole, the first through hole protrudes towards the inner side surface of the box body and is in a volcano mouth shape, the second through hole protrudes towards the inner side surface of the upper cover and is in a volcano mouth shape, the upper part of the outer side surface of the box body is recessed inwards, a ladder shape is formed below the outer side surface of the box body, the inner side surface of the upper cover is matched with the upper concave part of the outer side surface of the box body, the outer side surface of the annular cylinder is flush with the outer side surface below the box body, one end of the annular cylinder is arranged in the first through hole, the other end of the annular cylinder is arranged in the second through hole, the two ends of the annular cylinder are respectively folded outwards after being punched, so that the box body and the upper cover are tightly buckled together. The design of the inward concave of the box body is more convenient for the assembly of the upper cover after the filler is filled, the design of the annular cylinder enables the box body and the upper cover to be tightly buckled together without welding, and the production and assembly efficiency is greatly accelerated.
Preferably, the box body, the upper cover and the annular cylinder are made of stainless steel.
Preferably, the box body and the upper cover are manufactured by stamping, the forming is simple, the manufacturing cost is low, and the appearance is more attractive.
Preferably, the periphery of the dumbbell piece body is further coated with a buffer protective sleeve.
The invention has the beneficial effects that: the box body and the upper cover are manufactured by adopting punch forming, the forming effect is better, the appearance is more attractive, the concave design of the box body is more convenient for the assembly of the upper cover, the production efficiency is increased, the two ends of the annular cylinder are respectively turned outwards by punching, the box body and the upper cover are tightly buckled together, the production and assembly efficiency is greatly accelerated, the previous welding link is omitted, and the production cost is saved.
