Abstract

The utility model relates to a multi-key locking head mechanism capable of preventing technical unlocking, which belongs to the hardware lockset manufacturing industry. The mechanism consists of a multi-key key 1 and a multi-key groove lock cylinder 2. The mechanism changes the traditional unlocking mode that one key body is inserted into one lock cylinder groove, but adopts the unlocking mode that more than two (including two) key bodies on one piece of key are inserted into more than two (including two) key body grooves on one key cylinder, which means more than two pieces of keys unlock one lock. The traditional concept that one piece of key unlocks one lock is changed, and because many pieces of keys open one lock, the number of dense teeth is greatly increased, the mutual unlocking rate of the locking head is reduced, and at the same time, the difficulty in the technical unlocking by foreign matters is greatly increased.

Description

The mechanism of the anti-technical opening of a kind of many locking cams

Technical field: the utility model is the mechanism of the anti-technical opening of the many locking cams of a kind of lockset. belong to five metals lockset manufacturing industry.

Technical background: sell on the market at present, the employed lockset of users all is that a slice key is driven a lock basically, also basically can both be with the method for technical opening (that is: removing to dial pellet shot from a slingshot in the tapered end with special-purpose instrument) with the tapered end breakdown. and the utility model is exactly at this situation and the mechanism of the anti-technical opening of custom-designed a kind of tapered end solves this potential safety hazard.

The utility model content: the purpose of this utility model provides the mechanism of the anti-technical opening of a kind of many locking cams. and this mechanism comprises: many spoons of keys 1 (shown in figure one). many spoons of groove lock cores 2 (shown in figure two). it has changed the opening ways that a traditional spoon body inserts a lock core groove. but adopt a slice that 2 (containing 2) above spoon body inserts 2 (containing 2) above spoon body groove on the lock core opening ways is arranged on the key, so just be equivalent to drive a lock with the multi-disc key more than 2. changed the idea that traditional a slice key is driven a lock, owing to be that the multi-disc key is driven a lock, this has just increased the close number of teeth of key greatly, reduced the mutual opening rate of tapered end. simultaneously, also improved difficulty greatly, improved the theftproof performance of tapered end with the foreign matter technical opening.

Embodiment:

When many spoons of keys 1 are inserted many spoons of groove lock cores 2, be equivalent to insert simultaneously the multi-disc key more than 2 (shown in figure three).

In sum, advantage of the present utility model is as follows: (one) breaks through tradition. and design is unique. novelty. rational in infrastructure. (two) security insurance coefficient improves greatly. and (three) are because the design of this utility model breaks through tradition. novelty. close number of teeth height, the vi have high safety of anti-technical opening, mutual opening rate reduces greatly, estimates will monopolize a seat in the same industry.

Description of drawings: following structure accompanying drawing further specifies structure of the present utility model.

Accompanying drawing one is looked for many spoons of key masters of the utility model. left view.

Accompanying drawing two is analysed and observe for many spoons of groove lock cores of the utility model. front view.

Accompanying drawing three is analysed and observe for many spoons of keys of the utility model insert many spoons of groove lock core states. front view.

Claims

1. locking cam more than a kind is prevented the mechanism of technical opening, by many spoons of keys (1), many spoons of groove lock cores (2) are formed, it is characterized in that: described many spoons of keys (1) are at the spoon body that has on the key with a slice more than 2 (containing 2), and many spoons of groove lock cores (2) are at the spoon body groove that has on the same lock core more than 2 (containing 2).
