Description

The nut lock

Technical field

The utility model relates to lockset, relates in particular to the lockset that pins nut.

Background technology

At present, some is stolen easily with the part of appliance of fixed by nut.Doughnut for example, be with fixed by nut on wheel shaft, be easy to be backed out nut and steal tire by the people.

Summary of the invention

The purpose of this utility model provides a kind of nut lock, with the nut lock nut is pinned, and only has the people who holds key just can open lock, turns nut.

The structure of nut lock is: be made of tapered end and jam plate, tapered end be on tapered end a side be processed with by the suitable hole of locknut, the opposite side of tapered end is processed with lock core hole and two dead bolt holes, lock core is installed in the lock core hole, the dead bolt that stretches out to both sides is installed on the lock core, and dead bolt stretches in the dead bolt hole; The structure of jam plate is, a side of a block plate be processed with by the suitable circular hole of the lock diameter of bolt; The opposite side of steel plate is connected with two locks and corresponding with the position of dead bolt hole, and the head of two locks is processed with the opening suitable with dead bolt.

Using method is, when nut is installed, earlier jam plate is enclosed within on the bolt tightening nuts again, and the hole with the nut lock is stuck on the nut then, and the rotational angle lock enters in the dead bolt hole, and dead bolt inserts the lock opening, finishes installation work.Because nut is closed in the hole, other people can't turn, and the people who only holds key opens lock and just can take off lockset, turns nut.

Without key, the inside top face of two locks is designed to the inclined-plane in order to lock; As long as firmly press lower lock head, dead bolt promptly enters in the opening of lock along the inclined-plane.

In order to prevent to be prized from the slit of tapered end and jam plate by the people, the bottom of tapered end is provided with groove, and the flat shape size of groove is slightly larger than the flat shape size of jam plate, and the degree of depth of groove equals the thickness of jam plate, and jam plate is embedded in the groove.

The utility model has solved the stolen problem with the fixed by nut parts, and is especially stolen for vehicle tyre, more with practical value.
