Abstract

Aiming at the shortcoming of the present burglary lock, the utility model provides a burglarproof lock which prevents various unlocking tools and prevents from being drilled and smashed, i.e. a lock code decoding prevention device. The technical proposal of the utility model is as follows: the lock code decoding prevention device comprises a lock core. The utility model is characterized in that the lock code decoding prevention device also comprises a lock code decoding prevention plate and a key matching with the lock code decoding prevention plate, wherein the lock code decoding prevention plate with a hole is arranged in the front of the lock core. The hole of the lock code decoding prevention plate is a circular hole and is arranged above the lock core, at the same time, more than one groove is arranged on the edge of the hole. A column body is arranged between a toothed part and the key handle of the key matching with the lock code decoding prevention plate. The excellent combination design of the lock code decoding prevention plate and the key matching with the lock code decoding prevention plate causes that various professional unlocking tools can not be used in the design and can not open the lock of the utility model; meanwhile, because the lock code decoding prevention plate is made of high strength steel plates, the utility model has the functions of preventing from being drilled, smashed and pried.

Description

The anti-device of separating of code-locked

Technical field:

The utility model relates to a kind of lock, i.e. the anti-device of separating of code-locked.

Background technology:

Lock is people's requisite apparatus of living and work, and for antitheft, people bring into play various intelligence and wisdom, produce the various theftproof performance locksets that have.But because the fast development of unlocking technique makes the defective of many theftproof locks also all expose thereupon.General lock only just can be opened with unlocking tool, and can't damage lock.Present lock even if the performance of lock is good again, also is unable to undergo electric drill, hammers into shape and pound or prize firmly.

It is a special trade that formed gradually in recent years that specialty is unblanked.Be subjected to the influence of interests, there are some professional unlock staffs all to organize training class, even training accomplished on the net, make public security department's strictness forbid that this professional technique of promoting passed to the thief that should not pass to, only overlap professional unlocking tool just so present many thieves commit theft, be locked in unlocking person and thief in the eyes nothing but " scarecrow " with one.

Wrongful unblanking to social harm is conspicuous.Yet up to the present, the applicant also do not see any one tame Lock Factory can produce anti-pound, anti-drilling and can prevent the theftproof lock of various unlocking tools.

The utility model content:

The purpose of this utility model is the deficiency at present theftproof lock, and a kind of various unlocking tools and lock anti-drilling, that pound of preventing is provided, i.e. the anti-device of separating of code-locked.

The technical solution of the utility model is achieved in that a kind of code-locked is anti-and separates device, contains lock core, it is characterized in that also containing that the code-locked with holes that is provided with before the lock core is anti-separates plate and separate the key that plate matches with code-locked is anti-.

The utility model can also be achieved in that the anti-hole of separating plate of described code-locked with holes be circular hole and be arranged on lock core directly over, on the edge in hole more than one groove is arranged simultaneously.

The utility model can also be achieved in that described and code-locked is prevented separating the key that plate matches, and characteristics are that having of key is provided with a cylinder between tooth portion and the shank of the key, and cylinder can be cylinder or square body.

Beneficial effect:

Code-locked of the present utility model is anti-to be separated plate and prevents separating the synthetic merit design of set of keys that plate matches with code-locked, make various professional unlocking tools all can't in this design, use, can't open lockset of the present utility model, simultaneously since code-locked anti-to separate plate be to be made by high-strength steel sheet, so the utility model lockset also have anti-drilling and anti-ly pound, the function of pick-proof.

Description of drawings:

Accompanying drawing 1 is the anti-plate of separating of the code-locked before " one " font lock core.

Accompanying drawing 2 is to prevent separating plate bitting mutually with the code-locked of " one " font lock core.

Accompanying drawing 3 is the anti-plates of separating of the code-locked before " ten " font lock core.

Accompanying drawing 4 be with " ten " font lock core before code-locked anti-separate plate bitting mutually.

The specific embodiment:

Circulate extensively at present the lockset of use in market, its lock core generally all is " one " font and " ten " shape, and " people " font is also arranged certainly.

Embodiment 1 (Fig. 1), before " one " font lock core, be provided with high-strength material and make the anti-plate 1 of separating of code-locked of (for example stainless steel), code-locked prevents that it can be square separating plate 1, can single plate form, also can become a lockset part (promptly making the lockset part form), facing the lock core position has a circular hole 2, and the corresponding both sides of circular hole 2 have

groove

3,3 one-tenth " one " fonts of groove.Anti-to separate the key that plate 1 matches be rectangular plate shape with code-locked, and having has a cylinder 5 (also can be square body) between toothed portion 6 and the shank of the key 4, and the diameter of cylinder 5 prevents that with code-locked circular hole 2 diameters of separating on the plate 1 are identical or slightly smaller.

Embodiment 2, (Fig. 2), are provided with the anti-plate 1 of separating of code-locked that high-strength material is made (for example manganese steel) before " ten " font lock core, and the anti-plate 1 of separating of code-locked can be circular, can be a part of lockset.Face the lock core position and have a circular hole, the circular hole limit has four grooves, becomes " ten " font.Anti-to separate the key that plate 1 matches be " ten " font key with code-locked, has a cylinder 5 is arranged between toothed portion 6 and the shank of the key 4, and the diameter of cylinder 5 prevents that with code-locked circular hole 2 diameters of separating on the plate 1 are identical or slightly smaller.

During use, " one " font key or " ten " font key inserted have that code-locked is anti-to be separated in the lock core of plate 1, screw key because cylinder 5 on the key can rotate in the anti-circular hole of separating plate 1 of code-locked, can be unblanked.

If other keys, the special tool of the usefulness of for example committing theft, though also can insert in the anti-circular hole 2 of separating plate 1 of code-locked and in the lock core, owing to lack cylinder 5, and can not rotate, can not unblank.Meanwhile, bad lock core can not be pounded, be prized to stealer.

The utlity model has perfect design, also have anti-destructive and technique decodes.

Claims
