Abstract
The invention discloses a lock which comprises a lock body, a lock rod which is arranged on the lock body and a lock core which is arranged in the lock body. The lock also comprises a rotating column. One end of the rotating column is connected with the lock core, and the other end of the rotating column is provided with a lock slot for clamping the lock rod. The lock core drives the rotating column to rotate. A notch of the lock slot rotates to the lateral wall surface on the lock body, and the lock slot locks the lock rod tightly. 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
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, will add 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 making 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 is achieved by the following technical solutions: 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 described locking step, revolve and offer the locked groove that is used for the clamping locking bar on the post, during locking state, described locked groove is towards the side wall surface of locking step.
Preferably, described draw-in groove is a dovetail groove; Little dovetail groove can allow locking bar sticking in the draw-in groove freely in outer big.
Preferably, described 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 described post that revolves is a cylindrical structural; Cylindrical structural is the most simple and practical, and it is convenient to rotate.
Preferably, the described post that revolves is provided with a projection, described side wall surface offer one with the suitable retaining groove of described projection, during locking state, described 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 by 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
The invention will be further described below in conjunction with accompanying drawing:
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 schematic diagram.
The specific embodiment
As Fig. 1, Fig. 2 and Fig. 3 is the embodiment of a kind of lock of the present invention, this lock comprises lock body 1, 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 described 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, described locked groove 41 is towards the side wall surface 12 of locking step 11, and described locked groove 111 be a dovetail groove, outward greatly in little dovetail groove can allow locking bar sticking in the draw-in groove freely.Described 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 described post 4 that revolves is cylindrical structural, and cylindrical structural is the most simple and practical, and it is convenient to rotate.The described post 4 that revolves is provided with a projection 42, described side wall surface 12 offer one with the suitable retaining groove 121 of described projection, during locking state, described projection 42 holdings can well be rotated and to play position-limiting action in retaining groove 121 revolving post.
