Abstract

The utility model relates to a lock component, in particular to a key of an anti-theft lock core. A key handle is provided with an insertion slot; a pair of corresponding extrusion bumps are arranged in the insertion slot and are located on the key handle; the extrusion bumps are pressed into the insertion slot by being squeezed; a fixed through hole is formed in the tail of a key head; the tail of the key head and the insertion slot are in insertion match; the extrusion bumps are matched with the fixed through hole, and thus a fixed connection structure is formed. According to the structure, the key handle and the key head are in insertion match, the hemispherical extrusion bumps are pressed into the insertion slot from the outside after the insertion, the two extrusion bumps are pressed into the fixed through hole from two directions, thus the key handle and the key head are fixed, the connection between the key handle and the key head is not affected despite of the fact that the key handle and the key head are made of a same material or different materials, and the strength of the connection is very high, through the connection of plastic strips, different plastic strips can be arranged on the key handle to give the key handle different characteristics, and the key of the anti-theft lock core has stronger plasticity.

Description

The key of anti-theft lock

Technical field

The utility model relates to a kind of lock assembly, especially a kind of key of anti-theft lock.

Background technology

Modern lockset has developed more than 100 year, and people also study very thoroughly to its structure, mechanism, and therefore, the Method and kit for that just can open without key also emerges in an endless stream.In modern humans's civilized society, because various contradictions in society are very violent, people's ideological and ethical standard idea, values, the differences such as culture level, very different in the masses, kindhearted people can conscious standard factum, and " impolite be not ", though also can not rush without key.Yet those robbers that have no moral concept but utilize by every means high-tech means to force open the door and unblank, make numerous residents hard to guard against.

Lockset has the key matching, and key is all to adopt single metal material processing to form mostly at present; Key adopts unified thickness, and LOGO is used imprint process to print on key handle; So the non-constant of feel that not only causes key handle, and key LOGO is the operation of irreversibility.

Summary of the invention

The purpose of this utility model is, a kind of key that can realize the anti-theft lock that different materials splices, plasticity is high is provided.

The utility model solves the technical scheme that its technical problem adopts: a kind of key of anti-theft lock, comprise the shank of the key, key bit, the shank of the key is provided with a slot, in slot, be provided with the extruding salient point of a pair of correspondence, extruding salient point is positioned on the shank of the key, through extruding extruding salient point, is pressed in slot, the afterbody of key bit is provided with a fixed via, the afterbody of key bit is pegged graft and is coordinated with slot, and extruding salient point coordinates fixed via, forms fixed connection structure.

Of the present utility modelly further be set to: also comprise that limited bolt, limited bolt are arranged on slot side, limited bolt can arrange one or more.

Of the present utility modelly further be set to: with the position extruding of taper red needle slot outer wall on the shank of the key, the surface depressions of the shank of the key, charges into slot side, forms limited bolt.

Of the present utility modelly further be set to: described extruding salient point is hemispherical.

Of the present utility modelly further be set to: also comprise plastic paster, plastic paster is fixed on the surface of the shank of the key.

Said structure utilizes the shank of the key to coordinate with the grafting of key bit, after grafting, from outside, hemispheric extruding salient point is pressed in slot, two extruding salient points are pressed into fixed via from both direction, thereby the shank of the key and key bit are fixed, so no matter key bit and the shank of the key are homogeneity or unlike material, can not affect connection between the two, and the intensity connecting is very high, by the connection of plastic paster, different plastic pasters can be set on the shank of the key and make it a lot of different characteristics, make the utility model have stronger plasticity.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the present embodiment;

Fig. 2 is the floor map of the present embodiment;

Fig. 3 is for pushing the structural representation before salient point does not push;

Fig. 4 is the stereogram of the present embodiment;

The specific embodiment

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4 is known, the key of a kind of anti-theft lock of the utility model, comprise the shank of the key 1, key bit 2, the shank of the key 1 is provided with a slot 11, in slot 11, be provided with the hemispherical extruding salient point 3 of a pair of correspondence, extruding salient point 3 is positioned at the shank of the key 1 both side surface, and be wholely set with slot 11, through being pressed in slot 11, the afterbody of key bit 2 is provided with a fixed via 21, the afterbody of key bit 2 is pegged graft and is coordinated with slot 11, 3 pairs of fixed vias of extruding salient point 21 coordinate, extruding salient point 3 is pressed in fixed via 21 from both sides by extruding, achieve a fixed connection, two plastic pasters 4 are fitted in respectively on two surfaces of the shank of the key 1, realize being connected of plastic paster 4 and the shank of the key 1, limited bolt 5 is arranged on slot 11 sides, limited bolt arranges one or more.

Limited bolt 5 in the utility model arranges one or more, make key bit 2 be connected more stable with slot 11, after not having limited bolt 5 fixing, key bit 2 there will be the phenomenon of rocking, and the limited bolt 5 of the present embodiment is directly to push the shank of the key 1 by drift, and material sink and protrudes in slot 11, and be positioned at the side of key bit 2, and can make independent limited bolt 5, at the shank of the key 1, spacing hole is set, limited bolt 5 is squeezed into the shank of the key 1 inside from spacing hole.

In the present embodiment, in process, drift impact extruded salient point 3, makes to add convex point pressing 3 and sink, be pressed into fixed via 21, and the taper red needle on drift side is impacted the shank of the key 1 surface, make red needle squeeze material on the shank of the key 1 of opening, make it sagging, the pillared limited bolt 5 of shape, and be positioned at the side of slot 11, complete being fixedly connected with of key bit 2 and the shank of the key 1, and carry out spacing.

Plastic paster in the utility model has a lot of selections, is exactly the most simply such as plane decoration things such as trade marks, more complicated as buckled, the functional parts such as indicator, controller, be not limited to general plane indication or ornament.

The splicing process of the key that the utility model has solved anti-theft lock between different metal, and use reversible LOGO paster; The key of anti-theft lock adopts different metal splicing processing can make the feel of key obtain very large lifting, and reversible LOGO paster, for for the forming a complete production network of security door manufacturer, provides a set of single product to use the solution of multiclass LOGO.

Obviously, above-described embodiment is only used to done giving an example is clearly described, and the not restriction to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being extended out thus or change are still in protection domain of the present utility model.
