The purpose of this utility model provides a kind of lock body and cooperatively interacts with falling button, prevent to saw, cut, not, turn round, prize, pound, press, scratch novel padlock in one.

For achieving the above object, the solution that the utility model is taked is: with lock body with fall button and come design concept as an organic whole, lock body is with to fall the fastening close fit indispensable.Padlock by lock body, location filling member, fall to buckle three parts and form.Lock body with fall button and adopt the keyway combination.

Lock body with fall button and combine in the keyway mode after, by the location filling member lock body is being fallen to buckle the location, lock body can fall to buckle left rotation and right rotation, but can not before and after vertically move to break away from and fall to detain.Thereby lock body and the locking security function of falling after button combines have been realized.

Lock body with fall the mode that the button groove combines, make button be exposed to the external part of locked object, forgive in lock body inside, obtain the protection of lock body, solved fall button easily sawed, cut, not, turn round, prize the problem that loses function.The profile of lock body is two figures of eight that frustum is connected, and can fall to buckle left rotation and right rotation, common portable instrument, Qana incessantly, solved padlock body easily by not, turn round, press, pound the problem that loses function of destroying.Lock body adopts the keyway combination with falling button, does not have locking key, has also just solved the problem that present common padlock locking key easily goes to pot naturally.After lock body adopts alloy material processing, again through heat treatment sclerosis, shock resistance, anti-sawing; The location filling member is embedded in lock body inside and is subjected to lock body protection, has avoided this part to wreck and has caused padlock to lose the problem of function.

The utility model, reasonable in design, the structure uniqueness is compared with the padlock that uses in the present society, have significantly anti-ly saw, cut, prize, not, the advantage of turning round, scratch, pounding.Solved the unavoidable safety problem of present common padlock.Social benefit is obvious.

Below in conjunction with accompanying drawing, embodiment is further described in detail to the utility model.
