Abstract

The utility model relates to a novel bronze lock which comprises a lock case. A bronze lock cylinder is arranged in the lock case; the lock case is provided with a marble hole; a spring and a marble are arranged in the marble hole; and a keyhole is formed in the bronze lock cylinder. The novel bronze lock is characterized in that the keyhole runs through the bronze lock cylinder; the tail end of the bronze lock cylinder is provided with a screw thread; the lock case is surrounded by a layer of drilling resistant protection body; bumps are arranged inside the tail end of the lock case; the bumps are connected into an arc limiting port by a steel ring; reinforcing ribs are arranged in slots at both sides of the bronze lock; and furthermore, the tail part of the lock cylinder is provided with a tooth-shaped screw thread. The bronze lock disclosed by the utility model solves the problem of poor material intensity; the key slots are designed into through slots and are difficult to block; and meanwhile, the novel bronze lock has the characteristic of strong performance of preventing technical opening.

Description

A kind of new copper lock

Technical field

The utility model relates to a kind of lockset, relates in particular to a kind of new copper lock.

Background technology

Copper and compound unlike some heavy metal to the toxic effect of human body, China in all age, copper product (as Copper Pot, copper basin and copper water receptacle) used several thousand, copper has been showed the green face of its friendliness to the mankind, the mankind will rationally use copper to greatest extent, make the maximum benefit of its performance.Copper has the effect of eliminating bacteria.So public hygienic environment, particularly the place copper lock as hospital, shop, airport, station has obtained extensive use.

Existing lock core all is iron or copper machining, and its structure is except key, and other parts all are solid constructions, the ten minutes waste material, and copper price height increases the cost of lock core.

And when the design key, be obstructed structure, as when having foreign matter to inject keyhole, key then can't inject, and lock can't be opened, thereby the scope of application of lock is restricted.

The utility model content

The purpose of this utility model is in order to remedy the defective of prior art, and a kind of new copper lock is provided, and it is relatively poor to have solved the strength of materials, the lock core easy fracture, and key is designed to groove, is difficult for stopping up.

A kind of new copper lock includes lock housing, is provided with copper lock core in the described lock housing; the pellet shot from a slingshot hole is arranged on the lock housing; pellet shot from a slingshot is equipped with spring in the hole, and pellet shot from a slingshot is provided with keyhole in the described copper lock core; it is characterized in that; described keyhole runs through described copper lock core, and the tail end of described copper lock core is provided with screw thread, and described lock housing is surrounded the anti-drilling protective of one deck outward; and be provided with protruding block in lock housing tail end inside, protruding block is linked to be the limited mouth of arc with steel ring.

A kind of preferred version is described a kind of new copper lock, is provided with reinforcing rib in the groove of both sides.

A kind of preferred version is described a kind of new copper lock, is provided with the tooth form screw thread at the lock core afterbody.

Have very high impact strength, adopting keyhole to run through the copper lock core purpose is that if foreign matter is arranged, key inserts in the keyhole, can eject foreign matter.

The utility model has the advantages that:

A kind of new copper lock, it is relatively poor to have solved the strength of materials, the lock core easy fracture, and key is designed to groove, is difficult for stopping up, and has the characteristics that prevent that the technical opening performance is strong simultaneously

Description of drawings

Fig. 1 is the utility model overall appearance figure

Fig. 2 is the utility model structural representation sectional view

Wherein lock pin 1, lock housing 2, lock body 3, key 4, foreign matter 5, spring 6, pellet shot from a slingshot 7, keyhole 8, anti-drilling protective 9, limited mouth 10, projection 11.

The specific embodiment

A kind of new copper core lock comprises lock housing 2, and described copper shell skin is covered as anti-drilling protective 9, be provided with copper lock core 1 in the described lock housing 2, the pellet shot from a slingshot hole is arranged on the lock housing 2, spring 6 is installed in the pellet shot from a slingshot hole, pellet shot from a slingshot 7 is provided with keyhole 8 in the described copper lock core 1, and keyhole 8 runs through described copper lock core 1;

In order to prevent that artificially bigger, the foreign matter 5 with viscosity places in the lock body, at lock housing 2 tail ends, 3-5 projection 11 is set, add circular limited mouth 10 in projection,

The tail end of described copper lock core 1 is provided with screw thread, when if foreign matter 5 is arranged, key 4 inserts in the grooves, can eject foreign matter 5. in the keyhole 4

Copper material is wear-resisting, compares other material lock cores and can get well aspect functional performance a lot, and copper lock core is wear-resisting, and it is also easy to process, and is exactly not prevent fires, so at the external anti-drilling protective of one deck that added of lock housing, protective is steel material.

The utility model compared with prior art has following advantage:

1, a kind of new copper lock of the utility model and key, handled easily is applicable to driver's drawer cylinder lock, crew's drawer cylinder lock, pick-proof, theftproof performance is good, the function that reduces wear.

Above content be in conjunction with concrete preferred embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill under the utility model, under the prerequisite that does not break away from this utility model thinking, can also make simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
