Abstract

The invention discloses a lock which comprises a lock body. A lock rod and a lock core are arranged on the lock body. A locking step is arranged on the lock body above the lock core. A rotating column connected to an upper end of the lock core is arranged in the locking step. A lock slot for clamping hte lock rod is opened on the rotating column. During a locking state, the lock slot faces a sidewall surface of the locking step. With the simple and skill structure, the lock can indirectly rotate a neck on a locking device by a key to lock. No spring or billiard is required to be arranged in the internal structure of the lock. And no corresponding billiard slot is required to be arranged on the lock rod. The lock has the advantages of simple manufacturing, low cost, practicality and firmness.

Description

A kind of lock

Technical field

The present invention relates to a kind of lock.

Background technology

Lock be in people's daily life in order to a kind of utensil of the anti-theft protection property of locking a door, be commonly called as " goalkeeper army ".China uses lock to be the history in existing more than 5000 year of service for life.In the very long years, along with the continuous development of human civilization, the purposes of lock constantly enlarges, and the scope of application is more and more wider.From ancient times to the present, the locking industry of China is all very flourishing.The modern mechanical lock has had the history in more than 100 year, with having added pellet shot from a slingshot different in size in the lock core, outside line to open with the key of corresponding profile of tooth.Coded lock, magnetic lock, electronic lock, laser lock, acoustic control lock etc. had been developed into afterwards.Usefulness in people's daily life at ordinary times, the person of unblanking all heads into all pellets shot from a slingshot topmost with key or special tool(s), by means of torsion; By means of the terrace between the inside and outside lock core marble hole; Under the effect of spring force, pellet shot from a slingshot falling, outer pellet shot from a slingshot hinder outside internal cylinder in making, thereby open lock.Yet, this type of lock construction or more complicated, the accessory of processing lock needs is also many, such as pellet shot from a slingshot, spring etc.In the structure of lock, also to open corresponding bullet groove on the locking bar.Play a role thereby cooperate, cost is higher comparatively speaking.

Summary of the invention

The object of the present invention is to provide a kind of simple and ingenious structure, make simple and easy, low-cost, practical and firm lock.

In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: comprise lock body, lock body is provided with locking bar and lock core, it is characterized in that: the lock body of lock core top is provided with a locking step; Be provided with the post that revolves that is connected the lock core upper end in the said locking step; Revolve and offer the locked groove that is used for the clamping locking bar on the post, during locking state, said locked groove is towards the side wall surface of locking step.

Preferably, said draw-in groove is a dovetail groove; Little dovetail groove can let locking bar sticking in the draw-in groove freely in outer big.

Preferably, said draw-in groove is a U-lag; U-lag also well blocking live locking bar, in the time of can also avoiding locking device to rotate, serious friction between draw-in groove and the locking bar, thereby cause the parts strain, shorten application life.

Preferably, the said post that revolves is a cylindrical structural; Cylindrical structural is the most simple and practical, and it is convenient to rotate.

Preferably, the said post sidewall that revolves is provided with a projection, said projection be in locked groove under, said side wall surface offer one with the suitable retaining groove of said projection, during locking state, said projection holding is in retaining groove; Can well play position-limiting action to revolving the post rotation.

Compared with prior art, advantage of the present invention is: rotate the draw-in groove that revolves on the post indirectly through key and just can lock simple and ingenious structure.Need in the internal construction of lock, spring and pellet shot from a slingshot be set, thereby need on locking bar, not offer corresponding bullet groove yet, make simple and easy, cost reduction and very practical.

Description of drawings

Below in conjunction with accompanying drawing the present invention is described further:

Fig. 1 is the structural representation of a kind of lock of the present invention;

Fig. 2 is a lock body bottom schematic view of the present invention;

Fig. 3 is that the present invention removes and revolves the rod structure sketch map.

The specific embodiment

Like Fig. 1, Fig. 2 and Fig. 3 embodiment for a kind of lock of the present invention, this lock comprises lock body 1, and lock body 1 is provided with locking bar 2 and lock core 3; The lock body 1 of lock core 3 tops is provided with a locking step 11, be provided with in the said locking step 11 be connected lock core upper end revolve post 4, revolve and offer the locked groove 41 that is used for clamping locking bar 2 on the post 4; During locking state; Said locked groove 41 is towards the side wall surface 12 of locking step 11, and said locked groove 111 be a dovetail groove, outward greatly in little dovetail groove can let locking bar sticking in the draw-in groove freely.Said locked groove 41 is a U-lag, U-lag also well blocking live locking bar, in the time of can also avoiding locking device to rotate, serious friction between draw-in groove and the locking bar, thereby cause the parts strain, shorten application life.The said post 4 that revolves is cylindrical structural, and cylindrical structural is the most simple and practical, and it is convenient to rotate.Said post 4 sidewalls that revolve are provided with a projection 42; Said projection be in locked groove under, said side wall surface 12 offer one with the suitable retaining groove 121 of said projection, during locking state; Said projection 42 holdings can well be played position-limiting action to revolving the post rotation in retaining groove 121.
