Abstract

The utility model relates to a lock core belonging to lock core device art field, comprising a lock core head and a lock core body. It is characterized in that the lock core head and the lock core body are connected into a whole in split-combined type, which is realized by that: a groove is arranged in the lock core head; a convex stage which can be inserted into the groove in the lock core head is arranged at the joint of the lock core body top and the lock core head; a convex stage is arranged outside the lock core head; and a groove which can be jammed with the convex stage of the lock core head is arranged at the joint of the lock core body top and the lock core head. The lock core of the utility model can overcome the defects existing in prior art, retain the advantage of copper lock good appearance, reduce cost, and overcome the defect of high lock core price, having very strong competitive market position.

Description

A kind of lock core

One, technical field

The utility model relates to a kind of lock core, belongs to lockset lock core device technical field.

Two, background technology

Normally used lockset lock core is an integral type copper lock core, and the surface presents the gold of copper material, appearance looks elegant, but since copper material price very high, cause the on the high side of lockset lock core, be unfavorable for market competition.

Three, summary of the invention

The utility model provides a kind of advantage that can either keep appearance looks elegant, can reduce cost, overcome lock core defective on the high side again, increases the lock core of the market competitiveness.

The utility model is achieved through the following technical solutions:

A kind of lock core includes lock core head, lock core body, and special character is that lock core head, lock core body connect as one for the split convolution;

Described lock core head, lock core body split convolution connect as one in the following manner and realize:

1, be provided with groove in the lock core head, the top of lock core body, be provided with lock core head junction and can cooperate the boss that injects lock core head groove the inside, groove cooperates clamping with boss be one;

2, the lock core head is provided with boss outward, the top of lock core body, is provided with lock core head junction and can cooperates the groove that snaps on the lock core head boss, and boss and groove fit clamping are one;

Described lock core head, lock core body adopt two kinds of different materials to make respectively;

Described lock core head adopts the surface to present golden copper material and makes, and the lock core body employing neither influences other lower again material of its functional performance cost makes, and can adopt steel or alloy material or powdered metallurgical material or plastics to make;

Being connected to one by bayonet lock between described lock core head, the lock core body, mainly is riveted joint.

A kind of lock core of the present utility model, because lock core head, lock core body adopt two kinds of different materials to make respectively, the lock core head adopts the surface to present golden copper material and makes, the advantage that can keep various lockset appearance looks elegant, the lock core body employing neither influences other low again material of its functional performance, cost and makes, can reduce cost, overcome lock core defective on the high side, have the very strong market competitiveness.

Five, the specific embodiment

With reference to figure 3-5, provide specific embodiment of the utility model, be used for the utility model is further specified, but embodiment of the present utility model is not limited to following examples.

Embodiment 1:

Among Fig. 3,5, a kind of lock core includes lock core head 1, lock core body 2, and lock core head 1, lock core body 2 connect as one for the split convolution, realizes in the following manner:

Be provided with groove 3 in the lock core head 1, the top of lock core body 2, be provided with lock core head junction and can cooperate the boss 4 that injects lock core head groove the inside, groove 3 cooperates clamping with boss 4 be one; Lock core head 1 adopts the surface to present golden copper material and makes, and lock core body 2 employing steel or alloy material or powdered metallurgical material or plastics are made, and are connected to one by bayonet lock 7 between lock core head, the lock core body.

Embodiment 2:

Among Fig. 4, a kind of lock core includes lock core head 1, lock core body 2, and lock core head 1, lock core body 2 connect as one for the split convolution, realizes in the following manner:

The outer boss 5 that are provided with of lock core head 2, are provided with lock core head junction and can cooperate the groove 6 that snaps on the lock core head boss top of lock core body 2, the slot of the boss 5 of groove 6 formation lock core heads 2, and boss 5 cooperates clamping with groove 6 be one; Lock core head 1 adopts copper material to make, and lock core body 2 employing steel or alloy material or powdered metallurgical material or plastics are made, and is firm by rivet 7 riveted joints between lock core head, the lock core body.

A kind of lock core of above embodiment all can overcome the defective that prior art exists, and has both kept the advantage of various lockset appearance looks elegant, can reduce cost, overcome various lockset lock cores defective on the high side again, has the very strong market competitiveness.
