Abstract
The utility model relates to a kind of dumbbell, comprise handle, be arranged on two counterweights that handle two ends are silk head, the cold drawn forming being arranged on handle two ends by silk head, two described balance weight body outer surfaces are provided with coating, and described counterweight is connected with silk head thread by screw, and the counterweight cost of manufacture of cold drawn forming is low, reduce electroplating time, avoid sand holes to repair, lower cost of manufacture, decreasing pollution, counterweight is threaded with handle and firmly not easily gets loose, and can split packed and transported convenient in transport.
Description
Technical field
The utility model relates to a kind of dumbbell.
Background technology
Present hexagonal dumbbell counterweight is all Cast Iron Production, obtains through casting, the ball blast that removes sand, lathe process, tapping, sand holes repairing, polishing, plating; Series of processes, wherein each counterweight of lathe process needs processing eight faces, and often process a face and all counterweight will be taken off, install, correct, the loaded down with trivial details energy consumption of operation is large, and cost of manufacture is high, complex process.Only the machined expense of octahedral just accounts for 41% of counterweight production cost, because material is 18
#the pig iron, therefore electroplating time is very long otherwise do not reach effect.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of cost is low, the simple dumbbell of manufacture craft.
For solving the problem, technical solution adopted in the utility model is: a kind of dumbbell comprises handle, is arranged on two counterweights that handle two ends are silk head, the cold drawn forming being arranged on handle two ends by silk head, two described balance weight body outer surfaces are provided with coating, and described counterweight is connected with silk head thread by screw.
Furtherly, adhesive linkage is provided with between described screw and silk head.
Furtherly, described handle is provided with annular knurl.
Furtherly, described counterweight is hexagonal prism chamfering.
The good effect that the utility model produces is: the counterweight cost of manufacture of cold drawn forming is low, reduces electroplating time, avoids sand holes to repair, lower cost of manufacture, decreasing pollution, counterweight is threaded with handle and firmly not easily gets loose, and can split packed and transported convenient in transport.
In use, in order to avoid breeding gets loose, bonded adhesives is set when breeding and being connected with handle, disposable breeding is fixedly connected with handle, connect more reliable.
Handle arranges annular knurl and is conducive to user and holds anti-sliding stop.
The breeding of six cylinders is placed at dumbbell and can not be rolled on the ground, and smooth outer surface after lead angle, does not have corner angle to prevent scratch, prevents rolling from causing accidentally injuring.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model using state structural representation;
Fig. 3 is the A portion enlarged drawing structural representation of the utility model Fig. 2;
In the accompanying drawings: 1 handle, 2 heads, 3 coating, 4 counterweights, 5 screws, 6 adhesive linkages.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, utility model is described in further detail:
As Figure 1-3, a kind of dumbbell, it comprises handle 1, be arranged on handle 1 two ends is silk 2, two counterweights 4 being arranged on the cold drawn forming at handle 1 two ends by silk 2, two described counterweight 4 external surfaces are provided with coating 3, described counterweight 4 is threaded by screw 5 and silk 2, counterweight 4 cost of manufacture of cold drawn forming is low, reduce electroplating time, sand holes are avoided to repair, lower cost of manufacture, decreasing pollution, counterweight is threaded with handle and firmly not easily gets loose, and can split packed and transported convenient in transport; Be provided with adhesive linkage 6 between described screw 5 and silk 2, in use, in order to avoid breeding gets loose, bonded adhesives be set when counterweight is connected with handle, solidify rear formation adhesive linkage 6, disposable counterweight to be fixedly connected with handle, connect more reliable.Coating 3 is electrodeposited coatings.
Described handle 1 is provided with annular knurl, and handle arranges annular knurl and is conducive to user and holds anti-sliding stop.
Described counterweight 4 is hexagonal prism chamfering.The counterweight of six cylinders is placed at dumbbell and can not be rolled on the ground, and smooth outer surface after lead angle, does not have corner angle to prevent scratch, prevents rolling from causing accidentally injuring.
And triangle, corner and five jiaos of dumbbells can be produced when not changing any equipment, flexible and changeable.
When counterweight is produced, direct round steel cold drawn forming is six cylinders, segment, lead angle, tapping, polishing, plating; Owing to being cold drawn forming, the counterweight blank surface after segment is smooth, without machined and repairing, direct lead angle, then carries out polishing, electroplates, because material is Q235B round steel, electroplating time shortens 25% than cast iron, and counterweight has just been produced, and the cost of each counterweight reduces by 48.24%.
