Abstract
The utility model provides a locking torsion spring for a chain, which comprises a torsion spring main body, wherein a fixed hook and a lap hook are respectively arranged at the two end parts of the torsion spring main body. The locking torsion spring for the chain can facilitate the fixation of the chain, shorten the packaging time of the chain, and reduce the labor intensity.
Description
Technical field
The utility model relates to chain and makes the field, is specifically related to chain locking torsion spring.
Background technique
After finishing, the chain manufacturing needs to pack, the chain industry adopts the mode that wood spool or iron axle twine chain to pack usually at present, when chain is wound to end, for prevent that chain is scattered in transportation process, often adopt thin wire that end is fixed on the axle, waste time and energy like this, increased the packing time greatly, improved labor intensity.
Summary of the invention
Technical problem to be solved in the utility model is to provide chain locking torsion spring, can make things convenient for the fixing of chain, shortens the packing time of chain, reduces labor intensity.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: chain locking torsion spring, comprise the torsion spring main body, and the end, two ends of described torsion spring main body is respectively equipped with stay hook, overlap joint hook.
As preferably, described stay hook intersects mutually with the overlap joint hook, and the hook portion of described stay hook is corresponding inwardly with the hook portion that overlaps hook.When stay hook outwards strutted respectively with the overlap joint hook, the torsion spring main body promptly produced inside elastic force to them, guaranteed the elastic recovery of stay hook and overlap joint hook.
As preferably, described torsion spring main body, stay hook, overlap joint hook are structure as a whole.Make simple.
As preferably, described overlap joint hook comprises overlap joint hook main body and overlap joint hook joint.
Beneficial effect:
The utility model adopts technique scheme that chain locking torsion spring is provided, and has made things convenient for the fixing of chain, has shortened the packing time of chain, has reduced labor intensity.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is a use schematic representation of the present utility model.
Embodiment
As depicted in figs. 1 and 2, chain locking torsion spring comprises torsion spring main body 1, and the end, two ends of described torsion spring main body 1 is respectively equipped with stay hook 2, overlap joint hook 3.Described stay hook 2 intersects mutually with overlap joint hook 3, and the hook portion of described stay hook 2 is corresponding inwardly with the hook portion of overlap joint hook 3.Described torsion spring main body 1, stay hook 2, overlap joint hook 3 are structure as a whole.Described overlap joint hook 3 comprises overlap joint hook main body 31 and overlap joint hook joint 32.As shown in Figure 3, during actual the use, when chain is wound to end, stay hook 2 is connected with the end of chain, struts the chain that overlaps hook 3 and will overlap on hook main body 31 and the wood spool and overlap, stay hook 2, overlap joint hook 3 tighten up under the elastic force effect of torsion spring main body 1, the end of chain is locked on the chain on wood spool, easy to use, shortened packing time of chain, reduced labor intensity.
