Car lock is a lock shrapnel. Its structure and unlocking tumbler lock with the general principle is different, each tooth tumbler lock is the key corresponding to the two marbles gullet, but shrapnel lock keyway each tooth corresponds to only a small piece of shrapnel. Shrapnel shape as: Lock heart is with steel production, larger than an ordinary lock lock heart, is cylindrical. The length and diameter of the lock just shrapnel and other big heart. As the annular cylinder lock, only a few millimeters thickness of the annular. Concave inner lock body back with two pairs (four) in the center of the long grooves were symmetrically arranged. The width of the groove corresponding shrapnel long relationship, slightly wider than the shrapnel little. The slightly wider width is easy to bomb shrapnel bomb at ease on into the long groove. After the lock body suit locked heart, shrapnel central square hole is formed keyhole. That key is inserted into central unlocking of shrapnel.
Car door locks generally tooth key. In the next lock heart shrapnel hole through the bottom of a small hole not, but this little hole there is a crack groove connected with shrapnel holes. Small hole is used means a small spring. The role of small springs that withstand shrapnel, let shrapnel can shrink when unlocking; when locking can be automatically ejected. Different length of each piece of shrapnel shrapnel holes above, the same width shrapnel holes. This determination of different shades on each key gullets. No key above the long recess, is in the form of fold flat with alveolar shape, both sides of the face that may be neck and neck for the convenience of people around, as long as the master key to be able to insert the key hole, you can reverse heart unlock the lock. This lock is usually in the locked state, due to the elastic force of the spring shrapnel, long recess aligned with the lock body shells back into the inner recesses, so lock heart by shrapnel stuck, you can not rotate. When the key inserted into the key hole lock heart, key shrapnel through the middle of the flat square shrapnel holes directly in the end, a recessed gullet on pressing piece of shrapnel, shrapnel will shrink back, just pull back to the circle and lock heart shaped outer edge is flat. Thus, within the shrapnel lock heart can not be jammed lock body, lock heart can turn the lock. If you take the right key to unlock, then recessed key on alveolar certainly gullet depth of the concave primary key on different key stretch into shrapnel shrapnel holes in the middle, do not be able to return to full compression shrapnel and lock heart round or the outer edge is flush with some shrapnel compression does not move, there is a part of shrapnel stuck in the lock body long recess inner bucket or some shrapnel been pushed back too much, more than the circular outer rim lock heart, shrapnel The other end of the long groove and stuck the other side of the lock body. Lock heart lock body is not completely isolated, you can not turn the lock heart lock. As long as there is a tooth key groove on the wrong tooth, it can not unlock.
This lock is generally 5 tooth key, there are five shrapnel and five springs. It's the key to the same two-thirds probability is 500, that is, after the production of more than 250 locks will have a lock is the same. Then by the manufacturers factory specifications given.
This lock has five shrapnel holes in addition, there is a hole card, a card device, purpose is to keep in mind when inserting key lock twisting outward or inward contraction prolapse lock around them. Heart key in the lock opening is also provided with a flap, blocking key opening. When inserted into the keys, key bumped flap, flap will automatically shrink to one side. After removing the key, it will bounce back. Therefore, it can prevent the car wash or when rain is water penetration lock heart key hole, causing parts to rust. In the heart of the rear end of the lock (inside) is connected with a pin card, it is used to control the installation in the vehicle door lock sandwich box switches. Lock box has a switch is directly mounted on the inside and outside door handle control. Handle some twist, hand twist, pull some skill, hand pull. Lock box that tongue like an ordinary door with a ramp-shaped built-in lock, it will shrink back, the door can be opened. There is also a button to control the ramp-shaped tongue of stuck. If so I pressed the button, but by twisting the handle to open the door is simply twist does not move, we can not open the door, have a key to open to unlock, then twist the handle to open the door. In the box there is a flat square lock vice tongue. It is in the rear doors locked, the key will be the anti-twist bolt sticking out of a kind of insurance. Its purpose is to install anti-car thieves with a long ruler inserted into the top of the ramp-shaped lock bolt from the edge of the slit window glass and rubber, after edging can open the door. Usually when you switch the door, you do not press the button, directly accessible by hand twisting the handle on the door can be opened. If you press the button, you have to use a key to open the lock. After unlocking twist 72 degrees for an extend into the key clockwise, and then hand twist door handle, the door can only be opened. In the case of closed door after door, to be locked, then put the key inserted into the key hole twist counterclockwise 180 degrees, it can lock insurance. So need car door, then twist clockwise 252 degrees shall hand reverse door handle to open the door.
