Description

Bindiny mechanism between lock body and the control cam

In general, the present invention relates to lock body and the bindiny mechanism of control between the cam.

What exactly, the present invention relates to is the theftproof lock that has lock housing that acts on the automotive steering structure.

This lock housing is columniform substantially, and there is the hole of a boring system inside, is used to install lock body.Lock body is to be made of a rotor that can rotate in the hole or lock core, and rotor links to each other with a control cam that drives dead bolt.

Generally, lock body and coupled cam or be made of one, or be before the lock housing of packing into, just to have fitted together.

But more and more frequent is that various theftproof lock component are used, and are respectively charged into automobile, and bring in constant renewal in.

Particularly, the control cam is the lock housing of packing in advance.

Theftproof lock must have a lock body, and its rotor must closely be connected with glide direction in rotation with the control cam.

The mechanism that realizes this tight connection or assembling should make when installing does not need special instrument, and part lacking of should trying one's best, so that manufacturing cost can adapt with the such large-scale production of auto industry.

In addition, this assembling must promptly be carried out on the installation site at a predetermined relative position of cam and rotor.Should guarantee simultaneously after the rotor rotation, (comprise the installation site) at an arbitrary position on, the user can not extract the rotor of lock body out from seat, and it is separated with the control cam.

In order to address these problems, the present invention has designed a lock body and the bindiny mechanism that controls cam, and the control cam is to be pre-installed in the lock housing of automobile anti-theft lock, and there is the plush copper of a connection usefulness end of lock body rotor, it and the hole mating reaction of controlling on the cam.It is characterized by: it has makes lock body and control cam in first kind of bindiny mechanism that glide direction is connected.This bindiny mechanism is on any relative angle position with the control cam at lock body works.Make lock body and control cam in the another kind of bindiny mechanism that glide direction is connected simultaneously in addition, it works when lock body and cam are in a definite relative angle position at least.

According to another feature of the present invention:

---the method for attachment of first kind of glide direction be connect establish on the plush copper groove be used for control cam on a ratchet match;

---there is an arm to be used for when lock body and control cam are in a unique relative position, can inserting lock housing on the ratchet;

---this unique relative position is the rigging position of lock body and control cam;

---there is an inclined-plane end that connects plush copper;

---the method for attachment of second kind of glide direction is to be made of the radial arm that connects on the plush copper.

The present invention relates to a theftproof lock that acts on the automotive steering structure, it has a lock body and a control cam, and it is characterized by: control cam and lock body interconnect by a bindiny mechanism.

Further description by following can better understand the present invention, and corresponding accompanying drawing is:

---Fig. 1 is lock body and the vertical part sectioned view of theftproof lock lock housing before assembling that the control cam is housed;

---Fig. 2 is the rotor of the lock body with larger proportion seen from first projected angle and the axonometric drawing of control cam;

---Fig. 3 is identical with Fig. 2, just from another angle;

---Fig. 4 be among Fig. 1 along the sectional drawing of 4 lines, cam and rotor are at rigging position;

---Fig. 5 is that the lock body at rigging position is assemblied in the longitudinal sectional drawing on the control cam;

---Fig. 6 is identical with Fig. 4, and just lock body and the cam that links to each other are in another position, angle;

---Fig. 7 is identical with Fig. 5, lock body and the angle position of the cam that links to each other at Fig. 6.

We at first see Fig. 1, and it has shown by rotor 12 and connected thereon lock housing or the lock body 10 formed of stator 14, and lock can be with corresponding key 16 manipulations.

Lock body 10 can insert in the hole 18 of theftproof lock lock housing 20 in the direction of arrow F.

Loaded onto the control cam 22 that is used for handling dead bolt (figure does not draw) on the lock housing, dead bolt blocks a critical piece of automobile, as steering mechanism when the position of locking.

The mounting method of cam 22 in lock housing 20 do not belong to the present invention, is not illustrated here.

On the control cam 22 groove 24 is arranged, a ratchet 26 is equipped with in the inside, and ratchet is radially pulled to the axis direction of lock housing 20 by a spring 28.

By Fig. 2 and Fig. 3 as can be seen, rotor 12 is columniform substantially, and the known radial slot of people is arranged above, in order to pellet shot from a slingshot group (not drawing among the figure) to be installed.

Stretch out one on the face 32 relative on the rotor 12 and connect plush copper 34 with slotting key 16 one sides, its core be substantially one cylindrical.

In the both sides that connect plush copper core 35 and the 32 adjacent places, bottom surface of rotor 12 a pair of protruding pin that extends radially 36 is arranged, they are along the diameter positioned opposite.

On the perpendicular position of protruding pin 36, connect plush copper and extend radially out an arm 38 that is substantially rectangle, its end 40 protrudes in the external surface 42 of rotor 12.

On the position relative with radial arm 38, connecting on the plush copper 34 has groove 44 (see figure 3)s and an inclined-plane 46.

In Fig. 2 and Fig. 3, can see having to be used to insert a hole 48 that connects plush copper 34 on the control cam 22.Therefore two radial slots 50 that along diametric(al) distribute of shape corresponding to protruding pin 36 are arranged on the hole 48, be connected the corresponding radially narrow groove 52 of shape of the arm 38 of plush copper 34 with one.

Lock body 10 process of controlling cam 22 of packing into is as follows:

As shown in Figure 1 and Figure 4, control cam 22 is contained in the lock housing 20 by certain angle in advance, and this position and latched position the " STOP " position of theftproof lock (or be called) are different, are called " attached position ", to call the installation site in the following text.

In the installation site, the arm 54 of ratchet 24 faces the groove 56 on the lock housing 20.

When putting lock housing 20 into, lock body 10 connects the hole 48 that plush copper 34 is inserted control cam 22.

The bottom of ratchet 24 withstands on the inclined-plane 46 that connects plush copper 34, radially outwards slides, and compression spring 26, insert in the groove 56 of lock housing 20 end of the arm 54 of ratchet 24.

Along with the further insertion of lock body 10, connect groove 44 on the plush copper 34 and arrive the position relative with ratchet 24, under the effect of spring 26, ratchet insertion groove.

Under state shown in Figure 5, on the one hand lock body 10 and control cam 22 match being connected of realization rotation direction with radial slot on the hole 48 by protruding pin 36 radially.On the other hand, realize the connection of glide direction between the two by ratchet 24 and groove 44 cooperations on being connected plush copper 34.

In other words, under the effect of spring 26, ratchet 24 and groove 44 cooperations have constituted first kind of bindiny mechanism in direction of rotation, and as shown in Figure 6 and Figure 7, this bindiny mechanism is all effective when lock body 10 is in any relative angle position with control cam 22.

Fig. 7 in addition, the top 40 of radial arm 38 constitutes a boss corresponding to the hole seat 18 of lock body 10, and withstands on the end face of this hole seat, thereby forms lock body 10 and cam 22 being connected in glide direction.This connection is used in particular for the latched position of theftproof lock.

In other words, radial arm 38 constitutes second kind of bindiny mechanism in glide direction, and this mode is effective on a relative angle position different with the installation site at least.

Certainly, the present invention is not limited only to the example introduced, and it comprises the variation that all one skilled in the art can realize.
