Abstract

The utility model relates to a helmet with a lock for motorcycles. The utility model has the function of the prevention of a common helmet, and can be omnivorously locked on a suitable rod-shaped object. The back lower edge of the helmet is provided with a semicircular small opening. The body part of the lock is fitly fixed in the inner side of the semicircular small opening. The moving arm of the lock is connected with a main lock body through a fulcrum, and the moving arm can rotate around the fulcrum to run along one direction without hindrance. The moving arm which inversely runs can be blocked by the lock catch tooth of the lock, and the lock catch tooth of the main body is rotated in a lock body through a key for unlocking.

Description

The motorcycle Helmet with lock

The utility model relates to motorcycle helmet.It can not only make motorcycle helmet normally bring into play protective action, and motorcycle helmet can be locked on certain shaft of motorcycle or on other fixture conveniently.

At present, it is supporting that known motorcycle helmet does not all have lockset, because the helmet takes up space bigger, in driving out on tours, occasion such as do shopping, visit, the helmet is often had to take, and has become a not little little burden, and is both unbecoming also tangible inconvenient to handling other thing.

The purpose of this utility model just provides a kind of novel helmet.It neither influences the protective action of helmet essence, can be locked on the motorcycle simply when not using again, or other is local accordingly, thereby must take it everywhere and go.

The purpose of this utility model is achieved in that at the place, back lower edge of the helmet opens a semicircle osculum (the about 4cm of diameter), designs one and handcuff and similarly locks, and its major part is called main lock body, and movable part is called lever arm.King's lock body part ground that coincide is fixed on the inboard of this semicircle osculum by reinforcement, and lever arm has an end and main lock body one end hinge, and can rotate freely around this fulcrum.Lever arm can be gone everywhere without any hindrance here along a direction, then needs in the other direction to open with key, just can pass through.Owing to have such lock, the helmet be locked on the shaft, accurate this mouthful of pole pair firmly one leaned on.The lever arm of the lock week back of detouring is sealed with fixing main lock body, promptly reaches the simple and easy purpose that locks on the shaft of the helmet; If near the insufficient space the shaft to allow lever arm freely detour a week, can make lock be earlier and open shape, allow its lever arm follow the gap and insert and realize that lever arm cut-through thing makes lever arm sealed with fixing main lock body.

When need take off the helmet, only need lock to be opened with key, lever arm is separated with the main lock body of fixing, thus the desirable helmet down.

Owing to adopted such scheme, the helmet is locked on the various shape things of motorcycle simply, such as handlebar, shelf etc. are located, thereby must not be with on hand everywhere.Again because of the lock principle fairly simple, lock and open be restricted by conditions very little, flexible, safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1: locking fixes on the overall diagram of lower edge behind the helmet.

Fig. 2: the lever arm of lock.

Among the figure: 1, among the snap close tooth figure of main lock body 2, the helmet 3, key eye 4, lever arm 5, fulcrum 6, reinforcement 7, lever arm: main lock body (1) is fixed by a plurality of reinforcements (6) and the helmet; Main lock body (1) only reveals key eye (3) outside, and lever arm (4) is by fulcrum (5) and body lock (1) hinge, and lever arm (4) can be around fulcrum (5) operation, when lever arm (4) when being rotated counterclockwise, goes everywhere without any hindrance here; When clockwise operation, because the snap close tooth (7) of lever arm fastens with the snap close tooth (not drawing among the figure) of main lock body (1), can not pass through, without hindrance just need of clockwise operation inserted in the key eye (3) with key, the snap close tooth spiral of main lock body is entered the inside of main lock body (1), promptly unblank.

Obviously, can locate inboard trouble-free operation in the back lower edge of the helmet (2) for making lever arm (4), lever arm (4) and main lock body (1) are all along the inside bend of the helmet (2).
