Abstract
The utility model discloses an improved structure of a lock, which includes a lock body; a lock bar and a lock cylinder are arranged on the lock; a cavity body is arranged on the lock body above the lock cylinder; a through groove is formed on the wall of the cavity body; a rotating post connected with the upper end of the lock cylinder is arranged in the cavity body; a lock groove used for clamping the lock bar is formed on the rotating post; and when the lock is opened, the lock groove faces to the through groove on the cavity body. The utility model can fully protect the rotating post, thereby prolonging the service life of the lock; and more importantly, the rotating angle of the rotating post is not limited, the structural arrangement inside the lock body can be simplified, the manufacture can be simpler and more convenient, and the practicability is improved.
Description
Technical field
The utility model relates to a kind of improvement structure 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 improvement structure of existing a kind of lock, its simple and ingenious structure, it is to rotate the post that revolves that is arranged on the lock body indirectly by key, making locking bar enter to revolve draw-in groove on the post to form locks, locking bar can rotate by counterclockwise clockwise 360 degree, 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.But this type of post that revolves of locking setting fully is exposed to the outside, and well the significant points of protection lock reduces the application life of locking.Same, after revolving post and fully being exposed to the outside, the swing-around trajectory and the angle of revolving post all limit, and surpass the anglec of rotation, and lock will lose efficacy, and also need to be provided with corresponding structure and also guarantee the practicality of locking.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure of lock, and this simple and ingenious structure, manufacturing is simple and easy, cost is low, long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of improvement structure of lock, 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 cavity, offers a groove on the cavity body wall, be provided with the post that revolves that is connected the lock core upper end in the cavity, revolve and offer the locked groove that is used for the clamping locking bar on the post, during the lock opening, the groove of described locked groove on the cavity.
Preferably, described cavity top is with to revolve the column top contour; Described cavity overhead height is greater than the height that revolves the column top; When the cavity top is higher than or equals to revolve the column top, can better protect and revolve post.
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.
Compared with prior art, the utility model has the advantages that: cavity can be protected fully and revolve post, thereby prolongs the application life of this type of lock; the particularly important is, need not limit the anglec of rotation of revolving post, structure setting that more can simple and easy lock body inside; make simple and convenient more, practicality improves.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model lock body bottom schematic view;
Fig. 3 is that the rod structure schematic diagram is revolved in the utility model removal.
The specific embodiment
As Fig. 1, Fig. 2 and Fig. 3 is the embodiment of the improvement structure of a kind of lock of the utility model, 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 cavity 11, offer a groove 111 on cavity 11 body walls, be provided with in the cavity 11 be connected lock core 3 upper ends revolve post 4, after having this to be provided with, do not need to limit the rotational trajectory and the angular metric that revolve post, there is this can simplify the structure setting of each component in the lock body, being mainly reflected in does not have corresponding structure to limit to revolve post, and revolving post can 360 degree rotation, makes more simple.Revolve and offer the locked groove 41 that is used for clamping locking bar 2 on the post 4, during the lock opening, the groove 111 of described locked groove 41 on the cavity 11, described cavity 11 tops are with to revolve post 4 tops contour, described cavity 11 overhead heights are greater than the height that revolves post 4 tops, and described cavity overhead height is greater than the height that revolves the column top; When the cavity top is higher than or equals to revolve the column top, can better protect and revolve post, the significant points of protection lock just can prolong the application life of locking.Described locked groove 41 is a dovetail groove, outer big 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.
