Abstract
The utility model discloses a special key car lock for solving the disadvantages that the current key for the car lock adopting toothed key pin plug is usable by one face, with few bit codes and worse technical-opening prevention performance. In the structure of the special key car lock, plug pin holes are arranged vertically to the plane of a key groove on the plug of the lock; plug pin pits are respectively processed on the front face and the back face of the key blank according to the short and the long codes of the plug pins; the other structures are assembled by the parts of the original pin lock. The utility model not only solves the disadvantages of the current pin lock, but also improves the technical-opening prevention performance, safer and more reliable in application.
Description
Technical field:
The utility model relates to a kind of lock, particularly relates to a kind of lock with special construction key, goes into E05B19/00.
Background technology:
Greatly partly belong to cylinder lock in the market in the lock that is mainly used in the various models on the vehicles such as bicycle, motorcycle, electric motor car of Xiao Shouing.The characteristics of cylinder lock are that spring, tack pellet shot from a slingshot and lock core marble are housed in lock head component, lock core marble is contained in the lock core marble hole on the lock core, lock core marble and key are at grade, thereby key inserts lock core rear lock core pellet shot from a slingshot and drops on the key the teeth groove, then can realize unblanking by rotary locking cylinder as the two coding is identical.Therefore this key of locking all is to manufacture a toothed key according to the length of lock core marble and the number rear opening tooth of encoding on a side of key billet.There is following defective in this lock with band teeth key: can only use by single face when 1, key inserts key on the lock core, this gives and uses (especially under dark state) to make troubles; 2, available tartar coding is few; 3, anti-technical opening poor performance.These shortcomings are that the lock of band teeth key is intrinsic, and therefore, the lock with lock cylinder of various models mainly is moulding and structural variation, and the equal no change of structure of lock core and key (toothed).
The utility model content:
The purpose of this utility model is that a kind of special-shaped one by one key lock of lock with new structure key will be provided, to solve the defective that band teeth key lock exists.This special-shaped key lock can be achieved through the following technical solutions, it is made up of component such as moulding handle, rivet, stop, lock core, stop extension spring, tapered end rivet, cover plate, lock ring extension spring, lock housing, limit folder and key, and it is same or similar that its form of structure reaches cooperation each other, installation relation and crab tongs shape bicycle lock.Main points of the present invention be on the lock core with the key plane on lock core marble hole and the lock core in structure configuration each other in vertical state, also be that key inserts after the key key plane and lock core marble axis each other in vertical state.The making of key be on positive and negative two faces of key billet according to processing lock core marble hole (pit behind the lock core marble length coding respectively, hereinafter to be referred as the pellet shot from a slingshot hole), the spacing between the number in pellet shot from a slingshot hole, diameter, two adjacent pellets shot from a slingshot are cheated, all corresponding or coupling of the layout of pellet shot from a slingshot hole on the key billet face with the layout of lock core marble hole on lock core.The pellet shot from a slingshot of positive processing hole is identical with the pellet shot from a slingshot hole of reverse side processing on the key billet, is 180 degree counter-rotatings each other.Lock core of making according to technique scheme and key mix that various forms of other component promptly constitute various forms of special-shaped key locks on the former lock again.This lock is compared with the lock of existing band teeth key has following advantage: the key insertion lock core of 1, unblanking is not recognized positive and negative and all can be used; 2, available tartar coding is many; 3, key process technology height, not transreplication; 4, anti-technical opening performance is good, more secure and reliable to use.

The specific embodiment:
Special-shaped key lock of the present utility model, as shown in Figure 1: it is formed by moulding handle (1), rivet (2), stop (3), lock core (4), stop extension spring (5), tapered end rivet (6), cover plate (7), lock ring (8), extension spring (9), lock housing (10), limit folder (11) and key component such as (12).Wherein lock core upper lock core pellet shot from a slingshot hole and key plane in structure configuration each other in vertical state, after encoding according to lock core marble length as shown in Figure 3, Figure 4 on positive and negative two faces of key billet, process the pellet shot from a slingshot hole respectively, to make special-shaped key, the spacing between wherein the number in pellet shot from a slingshot hole, diameter, two adjacent pellets shot from a slingshot are cheated and layout such as the Fig. 2, shown in Figure 3 all corresponding on the key billet face with the layout of lock core marble on lock core.The pellet shot from a slingshot hole of positive and negative two faces processing is identical on key billet as shown in Figure 3, Figure 4, is 180 degree counter-rotatings each other.The effect of all the other component, cooperatively interact and install the relation with the crab tongs shape bicycle lock same or similar.According to the special-shaped key lock of above-mentioned parts process and assemble, when unblanking special-shaped key is inserted key, lock core marble falls on the key the pellet shot from a slingshot hole, identical as mutual coding, then rotatable lock core is opened lock, and is different as mutual coding, then lock core can't rotate, and lock is not opened.Reverse side inserts key no matter the front is inserted still as for key, and its effect is identical.
Claims (2)
1, a kind of by moulding handle (1), rivet (2), stop (3), lock core (4), stop extension spring (5), tapered end rivet (6), cover plate (7), lock ring (8), extension spring (9), lock housing (10), the special-shaped key lock that limit folder (11) and key (12) are formed, it is characterized in that lock core upper lock core pellet shot from a slingshot hole and key plane in structure configuration each other in vertical state, at key billet just, cheat the number in pellet shot from a slingshot hole on anti-two faces according to processing pellet shot from a slingshot respectively behind the lock core marble length coding, diameter, spacing between two adjacent pellets shot from a slingshot are cheated, the layout of pellet shot from a slingshot hole on the key billet face is all corresponding with the layout of lock core marble hole on lock core.
2, special-shaped key lock according to claim 1 is characterized in that the lock core marble hole that processes is identical on positive and negative two faces of key billet, be 180 degree counter-rotatings each other.
