Abstract
The utility model relates to a lock bolt device which comprises a lock body, wherein one end of the lock body is fixed with a sleeve cylinder of the lock bolt, and the other end of the lock body is hinged with a lock head assembly which is connected with one end of the lock bolt; the other end of the lock bolt is provided with a tabular lock bolt buckle; an open slot corresponding to the lock bolt buckle is arranged on the sleeve cylinder, and the opening width of the open slot corresponds to the thickness of the lock bolt buckle, so the lock bolt buckle can be inserted into the sleeve cylinder; a cavity which can enable the lock bolt buckle to rotate is arranged in the sleeve cylinder; the sleeve cylinder is a hollow square cylinder body or a hollow polygon prism body or a hollow cylinder body, the surface of the cylinder body of the sleeve cylinder is provided with strip-shaped open slots in the axial direction and in the radial direction, and the strip-shaped open slots are communicated with each other; each open slot forms an L shape; the lock bolt is designed into a square cylinder body or a polygon prism body or a cylinder, and the front end of the lock bolt is provided with a radial slot; one side of the radial slot extends out of the tabular lock bolt buckle. The utility model has the advantages of reasonable and simple structure and simple processes of the unlocking and locking; the cost is reduced because parts of the utility model are reduced, and the anti-theft performance is further increased because of the protection of a protection sleeve.
Description
Technical field
The utility model relates to a kind of lock, particularly a kind of locking bolt device.
Background technology
At present, existing theftproof lock all needs a step that locking bolt axially is pressed into sleeve when locking, so just need unblank back-moving spring, spring capping and axially mechanisms such as sliding sleeve realize this step, such anti-theft lock structure more complicated, manufacturing cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of simple and reasonable, low cost of manufacture, locking bolt device that anti-theft feature is strong, to overcome weak point of the prior art.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of locking bolt device, comprise lock body, an end of lock body is fixed with the locking bolt sleeve, and the other end of lock body is hinged with the tapered end assembly, the tapered end assembly links to each other with locking bolt one end, its architectural feature is that the other end of locking bolt is provided with tabular locking bolt button, and sleeve is provided with locking bolt and buckles corresponding open slot, and A/F is corresponding with locking bolt button thickness, make the locking bolt button can insert sleeve, sleeve inner is provided with the cavity that the locking bolt button is rotated.
Described sleeve is square body or the multiedge cylinder or the cylinder of boring, and its damaged surface axially and radially is provided with the strip open slot that communicates; Open slot is the L font; Or the telescoping column surface is axially arranged with the strip open slot; Be provided with rotating cylindric sheath in the described cylinder sleeve, sleeve and sheath are fixed together by shell fragment or elastic steel ball; Sheath is provided with and the corresponding open slot of sleeve; Described sheath open slot is L font or channel cross-section shape; Described locking bolt is square body or multiedge cylinder or cylinder, and its front end is provided with radial slot, and a side of radial slot is extended tabular locking bolt button.
The utility model is simple and reasonable, owing to reduced component, so reduced cost, the process of unblanking and lock is simple, because the protection of sheath has further improved theftproof performance.

The specific embodiment
Referring to Fig. 1-Fig. 3, a kind of locking bolt device, comprise lock body 7, an end of lock body 7 is fixed with locking bolt sleeve 1, and the other end of lock body 7 is hinged with tapered end assembly 3, tapered end assembly 3 links to each other with locking bolt 4 one ends, the other end of locking bolt 4 is provided with tabular locking bolt button 2, and sleeve 1 is provided with locking bolt and buckles 2 corresponding open slots, and A/F is corresponding with locking bolt button 2 thickness, make locking bolt button 2 can insert sleeve 1, sleeve 1 inside is provided with and can makes locking bolt buckle 2 cavitys that rotate.
Sleeve 1 is square body or the multiedge cylinder or the cylinder of boring, and its damaged surface axially and radially is provided with the strip open slot that communicates, and open slot is the L font; Locking bolt 4 is made as square body or multiedge cylinder or cylinder, and its front end is provided with radial slot, and a side of radial slot is extended tabular locking bolt button 2.
When locking, after inserting key, hold key, tapered end assembly 3 is swung to sleeve 1 place, because the thickness of locking bolt button 2 is corresponding with the open slot width, so locking bolt button 2 can insert in the sleeve 1, this moment key, locking bolt 4 drives locking bolt buttons 2 and turns an angle in the cavity of sleeve 1, because the radical length of locking bolt button 2 is bigger than the width of sleeve 1 open slot, so locking bolt button 2 can't be extracted out from sleeve 1, extracts key, finishes the action of locking.
Referring to Fig. 4-Fig. 7, be another embodiment of the utility model.Be provided with rotating cylindric sheath 5 in the sleeve 1, sheath 5 can buckle 2 by protection sleeve 1 interior locking bolt, and sleeve 1 is fixed together with sheath 5 elastic steel balls; Sheath 5 is provided with and sleeve 1 corresponding open slot; Sheath 5 open slots are L font or channel cross-section shape; Sleeve 1 can be made as and have only damaged surface to be axially arranged with the shape of strip open slot when using with sheath 5.
When locking; after inserting key; hold key; tapered end assembly 3 is swung to sleeve 1 place; after locking bolt button 2 inserts sleeve 1 and sheath 5; sheath 5 can be buckled 2 with locking bolt and rotate simultaneously; key, locking bolt 4 drives locking bolt button 2 and turns an angle in the cavity of sleeve 1, because the radical length of locking bolt button 2 is bigger than the width of the open slot of sleeve 1 and sheath 5; so locking bolt button 2 can't be extracted out from sleeve 1; can't find out that from sleeve 1 locking bolt buckles 2 position this moment, applies external force and also be difficult to locking bolt button 2 is damaged, and promptly sheath 5 plays a protective role; extract key, finish the action of locking.
Owing to be fixed with elastic steel ball 6 or shell fragment between sleeve 1 and the sheath 5, so locking bolt button 2 is extracted back sheaths 5 out and can not be rotated freely when unblanking, feasible when locking once more locking bolt button 2 can insert smoothly in sleeve 1 and the sheath 5.
