Abstract

The utility model relates to a motorcycle helmet with concealed lock which comprises a helmet shell, an inner pad, a lock body and a hook-shaped lock bolt. The utility model is characterized in that the lock body is built in the upper part of the helmet shell, the hook-shaped lock bolt can be drawn out of the edge of the motorcycle helmet with concealed lock by a set of linking mechanism and buckled and locked on a rear luggage carrier for motorcycle to prevent the motorcycle helmet with concealed lock from being stolen, and the hook-shaped lock bolt can be pressed into the helmet shell, which can not obstruct the motorcycle rider when the motorcycle rider wear the motorcycle helmet with concealed lock on the head, and the integrality of the appearance of the motorcycle helmet with concealed lock is kept.

Description

Motorcycle helmet with concealed lock

The utility model relates to a kind of crash helmet that uses by motorcycle the time, particularly a kind of motorcycle safety helmet with lock.

Known motorcycle helmet is not with lock, and the cyclist goes out to handle affairs, and when lock for motorcycle was parked in the roadside, the helmet was often stolen.Patent Office of the People's Republic of China announced on July 31st, 1991, name is called the utility model patent (notification number: CN2081650U of " motorcycle helmet with lock ", number of patent application: 90226493.1), the technical scheme of fixing a lock at position, helmet edge has been proposed, in embodiment, enumerated external u-shaped lock, three kinds of forms such as external split type lock and built-in lock, but the sort of form no matter, its lock body is all emphasized to be installed in helmet along the position.In this case, locking bolt must expose to beyond the helmet edge, both is in the way, and is also indecency.

The purpose of this utility model provides the stealthy motorcycle helmet of locking of a kind of tool, because the lock body and the locking bolt of this lock all are hidden in the helmet, when the helmet used, locking bolt was collapsible in the helmet, both has no relations, and does not destroy the outward appearance integrality of the helmet again.When motorcycle rests in the roadside, can be hidden in that locking bolt in the helmet is pulled out and with its padlock on the tailstock of motorcycle, reach antitheft purpose.

The technical solution of the utility model is as follows: lock body is partly ensconced the left side of inner helmet or the top of right side or rear side, make itself and helmet along keeping bigger distance, relevant position outside the helmet, only expose keyhole and retainer ring, between lock body and the hook-type locking bolt, one cover interlinked mechanism is arranged, and interlinked mechanism is made up of the flanged sleeve pipe in rotor, pendulum and lower end.The flanged end of sleeve pipe is overlapping the hook-type locking bolt of an end band piston.The hook-type locking bolt is by the piston of an end, in sleeve pipe, can slide up and down and left-right rotation, but because the flange of sleeve pipe lower end is to the resistance shelves of hook-type locking bolt piston, the hook-type locking bolt can not break away from sleeve pipe, the other end of sleeve pipe, make pancake, be connected the upper end of pendulum by rotating shaft with the lower end of pendulum, be connected with an end of rotor in the same way, the other end of rotor is fixed on the lock gall of lock body, and after key injected the lock body keyhole and rotates lock gall, the rotor that is fixed on the lock gall upwards rotated at once, thereby pulling pendulum, pendulum spurs sleeve pipe again, and sleeve pipe spurs the hook-type locking bolt of an end band piston by the flange of lower end, is fixed on helmet along in the positioning sleeve of interior relevant position because an end of hook-type locking bolt band piston is enclosed within, along with being pulled of piston, just rise along positioning sleeve, thereby the hook end of drive hook-type locking bolt makes the end insertion of hook end be fixed on helmet equally along in the lock bolt sleeve of interior relevant position, make the hook-type locking bolt fasten the motorcycle after-frame, at this moment, just can extract key, thereby finish the action of locking.When unblanking, equally key is injected the keyhole of lock body, the rightabout when locking rotates lock gall, be fixed on the rotor on the lock gall, just rotate, thereby promote pendulum, pendulum promotes sleeve pipe again, like this, be positioned at the flange of sleeve pipe lower end, just removed restriction, as long as lightly the hook-type locking bolt is pulled out hook-type locking bolt piston, and rotate it, just finished the action of unblanking.After lock is opened because pipe box has enough length, the hook-type locking bolt can be exposed at part below the shade outward behind the end alignment lock bolt sleeve of hook end, with hand with it fully by being hidden in helmet the inside.

The utility model has the advantages that not only lock body can be built in the helmet, locking bolt is same collapsible in the helmet when the helmet uses, and both has no relations, and does not destroy the integrality of helmet outward appearance again.

Below in conjunction with the description of the drawings, provide embodiment of the present utility model.

Fig. 1 is an outward appearance left view of the present utility model.

Fig. 2 is the unlocking condition schematic diagram.

Fig. 3 is the locking state schematic diagram.

Fig. 4 is for after unblanking, and the hook-type locking bolt conceals into the view in the helmet.

A kind of motorcycle helmet with lock, by helmet shell (1), interior pad (2), lock body (3), hook-type locking bolt (4) and interlinked mechanism constitute, lock body (3) is installed on the top of left side between helmet shell (1) and the interior pad (2) or right side or rear side and helmet along keeping bigger distance, have only keyhole and retainer ring to be exposed to outside the helmet shell (1), interlinked mechanism between hook-type locking bolt (4) and lock body (3), by rotor (5), pendulum (6), sleeve pipe (7) is formed, rotor (5) one ends are fixed on the lock body (3), the other end is connected by the upper end of rotating shaft (8) with pendulum (6), the lower end of pendulum (6) also is connected with the offset flat shape upper end of sleeve pipe (7) by rotating shaft (9), make between rotor (5) and the pendulum (6) and between pendulum (6) and the sleeve pipe (7), can be that rotate mutually at the center with rotating shaft (8) and (9) respectively, one end of hook-type locking bolt (4) tool piston (10) is enclosed within the sleeve pipe (7), and be subjected to the stopping of flange (11) of sleeve pipe (7) and can not break away from sleeve pipe (7), the external diameter of piston (10) becomes movingly with the internal diameter of sleeve pipe (7), in helmet shell (1) near the corresponding position on helmet edge, a positioning sleeve (12) and a lock bolt sleeve (13) are installed, after locking, one end of hook-type locking bolt (4) tool piston (10) and hook end are enclosed within respectively in positioning sleeve (12) and the lock bolt sleeve (13), after unblanking, the hook end is deviate from from lock bolt sleeve (12), piston end still is enclosed within the positioning sleeve (12), and can freely rotate in cover.
