Abstract

The utility model discloses a safety lock. A lock core of a lock is composed of two rows of marbles; a definite included angle can be formed between the two rows of marbles which are relatively staggered. A key which can be matched with the lock to use has the function that the key can not easily be copied. The lock still more has safety, security, and theft-proof performance. The utility model is suitable for the automobile, the motorcycle, the national safety security institution, the treasury and the gold safe which are in the banking system, the warehouse, the safe, and the security door which are in the important department, etc.

Description

A kind of safety lock

The utility model relates to a kind of lockset, particularly relates to a kind of two locks of lining up the lock cylinder of certain angle that have.

At present, the pellet shot from a slingshot of the lockset on the market is with by traditional single developed into two present rows, three rows, four rows, angle between them has 0 degree, 90 degree, 180 degree, strengthened the safety of conventional lock, but their common shortcomings are, all keys that are used for unblanking all have transreplication, and this is when a lot of occasions (as renting a house, borrow car, house decoration etc.) need a key to give other people temporarily, and it is very dangerous that the key of this transreplication just seems.And national security is maintained secrecy, and also should to have the replicability of being difficult for just safer for the key of departments such as office, banking system, important base.

The novel purpose of this use is to provide a kind of lockset, and the employed key of this lockset has the replicability of being difficult for, and reaches its safe antitheft function.

The purpose of this utility model is achieved like this: the heart-lock core of this lockset is to be made of the two row's lock pellets shot from a slingshot that form an angle, and two row's lock pellets shot from a slingshot are asymmetric, and stagger mutually again, as shown in the figure.

Fig. 1 is a structural representation of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing.

Lockset of the present utility model is the lock core that the lock core of common single lock pellet shot from a slingshot is made into two row's lock pellets shot from a slingshot, and as shown in Figure 2, two row's lock pellets shot from a slingshot have certain included angle X (10 °≤X≤60 °), and best angle is between 30 °～40 °.And two row lock pellet shot from a slingshot stagger relatively, as shown in Figure 3.This just transforms the heart of lock, is applicable to the lockset of any use key, and the characteristics of other original function of lockset are had no effect.More increased the safety of lockset.

Another part of the present utility model is the key that matches with lockset, its shape is very similar with common monorow tooth key, be that key of the present utility model has two row's key bits, has certain included angle (10 °≤X≤60 °) between two row's key bits, and the teeth of key bit stagger mutually, and both the protuberance of a heel teeth had blocked the recess of another heel teeth, so, the machine of electronics bitting can't be prepared, and also can't prepare by hand.So just take place from the incident of having stopped with this to steal by copy key.The symmetry if the teeth of two row's key bits differ has again just more increased the confidentiality of locking.In fact this key is exactly a key as driving a lock simultaneously with two different keys, uses easily.

Lockset of the present invention is compared with the lockset of prior art has following advantage: kept the conventional shape of former monorow tooth key, easy to use, safe and reliable, theftproof is strong, and is with low cost, and technology is simple, can produce good social benefit and economic benefit.

The processing of key is manufactured and is easy to, but must have very strong professional.Get than key bit sheet metal after a while and do the key material, be processed into basic model as shown in Figure 4, amount to into the key shape of using in the utility model by dotted line among the figure.Slot again, die mould, plating etc., one have certain angle, two rows are asymmetric, the novel key of the tooth that staggers is mutually again just manufactured and has been finished.Also can cast one-shot forming.

Claims (5)

1. safety lock, its lock core are to be made of two row's lock pellets shot from a slingshot, it is characterized in that two row's pellets shot from a slingshot become certain included angle (10 °≤X≤60 °).

2. lock as claimed in claim 1 is characterized in that the relative position of two row's pellets shot from a slingshot staggers mutually.

3. as claim 1,2 described locks, it is characterized in that the key that matches with it has two row's key bits, two row's key bits become certain included angle (10 °≤X≤60 °).

4. as the key of lock as described in the claim 3, it is characterized in that the teeth of two row's key bits stagger mutually.
