The utility model which can relieve the worry that a driver carries the helmet completely conforms to operation specifications of motorcycle (or motorbike) driving and a driving habit of a normal user.

Description

Lock-up motorcycle ignitor switch interconnecting device

The utility model relates to motor bike matching product technology, the linkage that particularly a kind of ignition lock that utilizes motor bike or light cavalry locks to Casque for motorcycle driver.

Present most of Casque for motorcycle driver (or safety cap) does not have anti-thefting facility, will carry in the use, because of reasons such as its volume shape use very inconvenience.And lock for motorcycle can only pin vehicle body, and the helmet is not had antitheft effect.

Because the ignition lock (being Oil Switch) of motor bike generally is to use key to realize the break-make of different gear circuit, does not have other function in addition again.And ignition lock is contained in the at arm's length extrusion position of headstock usually, therefore be particularly suitable in the helmet locks, being used, in view of this, the purpose of this utility model is to utilize a kind of motor ignition lock linkage that can lock to certain special Casque for motorcycle driver (reporting patent in addition) of existing motorcycle ignition switch designs, make the driver after motor stops, need only be locked in the helmet on the latch hook of ignition lock linkage smoothly, and needn't carry.

As shown in Figure 1, the technical scheme that realizes the utility model purpose is such, a drive link 8 of coaxial interlock with it is fixedly connected on the lock core 9 of ignition lock, the tail end of drive link 8 connects an eccentric cam 6, in the lock body 12 of ignition lock, establish a retaining bolt 4 that is socketed with pressure spring 5 and can does freely to stretch, also offer a locked groove on the lock body 12, in adorn the latch hook 1 of the retractable of a pressure spring 2 and a similar dead bolt effect, latch hook 1 can pin the retainer of the helmet.After the installation, one end of retaining bolt 4 and cam 6 pressured contacts, the other end can be pressured with the bayonet socket 3 that presses down on the latch hook 1 of back, in the time will driving, insert ignition key, rotational lock core 9, when connecting ignition lock, lock core 9 drives the drive link 8 that rotates synchronously with it and then drives cam 6 and rotates, cam 6 makes retaining bolt 4 inside retractions again, latch hook 1 is released (under its base pressure spring 2 application forces upwards (outer) and ejects, and can take out the helmet and use, when stopping working, the retainer place of the helmet is inserted in the shackle portion 13 of latch hook 1, press down latch hook 1, allow retaining bolt 4 snap in its bayonet socket 3, can pin the helmet.

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

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 is the scheme drawing of the utility model at blocking;

Fig. 3, the connection diagram of cam drive bar and retaining bolt;

Fig. 4 makes the scheme drawing that semicircle shackle portion locks to the helmet with latch hook;

Fig. 5 is a scheme drawing of directly making shackle portion on retaining bolt.

Wherein: 1 latch hook, under the 2(latch hook) pressure spring, 3 bayonet sockets, 4 retaining bolts, 5 springs, 6 cams, 7 ignition lock bodies, the 8(cam) drive link, 9 lock cores, 10 blocks, 11 backing pins, 12 lock bodies, 13 shackle portions, 14 semicircle shackle portion (see figure 4)s, 15 helmets, the 16(retaining bolt) shackle portion.

With reference to accompanying drawing 1, retaining bolt 4 wherein is laterally that (level) is arranged in the lock body 12, and latch hook 1 is and vertically is installed on the lock body 12, and after latch hook 1 pressed down, the breach of its shackle portion 13 was blocking by touching the upper surface at lock body 12.

From Fig. 1,2,3, all can find out, be socketed in the spring 5 on the retaining bolt 4, the one end is pressed on the block 10 that links to each other with lock body 12, and the other end is pressed on the backing pin 11 that links to each other with retaining bolt 4, under the effect of pressure spring 5, make retaining bolt 4 have forward the trend that (left) stretches out.

With reference to Fig. 4, the utility model also can be designed to the another kind of form that the helmet 15 is locked on latch hook 1, promptly when the shade place of the helmet 15 be when making arc cage knob (as the semicircle cage knob), in order the helmet 15 of this semicircle cage knob to be locked, also latch hook 1 can be designed to become as shown in Figure 4 the structure of semicircle shackle portion 14, when depressing latch hook 1 and lock, its semicircle shackle portion 14 is positioned at the side of lock body 12 and cooperates with this side and forms a kind of closure state the helmet 15 that has the semicircle cage knob is locked jointly.

With reference to Fig. 5, the utility model structure also can be designed to more convenient form, can be shaped on shackle portion 16 by direct tail end at retaining bolt 4, can save latch hook 1 and pressure spring 2 like this.Allow shackle portion 16 cooperate with the side of lock body 12, when retaining bolt 4 retractions, the breach of its shackle portion 16 is blocking by touching the side at lock body 12.When inserting ignition lock key rotation lock core 9, it is protruding to make cam 6 drive retaining bolt 4, the open end of its shackle portion 16 exposes, can take out the helmet uses, when handling affairs when stopping, rotational lock core 9 makes cam 6 drive retaining bolt 4 and inwardly shrinks, allow the open end closure (sides of shackle portion 16 tight pressured lock bodies 12) of shackle portion 16, can pin the helmet.

The utility model when mounted, can allow the ignition lock latching surface towards chaufeur inclination certain angle so that the user is pressed into latch hook to the helmet locks.The utility model can make full use of the ignition switch device of existing motor, has exempted the worry that chaufeur must be carried the helmet, uses very conveniently, and meets operating instruction that motor drives fully and common user's driving is accustomed to.
