Abstract

The utility model discloses a miniature safety key, including handle and key bit, handle and key bit are connected, the key bit is a dull and stereotyped design, and that divides upper strata and lower floor flat board on sets up first key bit layer and second key bit layer, attend and distinguish between the lower floor at a distance from certain distance, upper strata and lower floor's key bit be the range of cockscomb structure. The utility model discloses characteristics are that its holistic technical design theory does: piecing together the design with two sets of key meshings and being an overall structure for attending the lower floor, make great of the dwindling of width of its key, the change volume of key bit can not reduce, and anti -riot power is more effective, extends to volume of the dwindling of lock core simultaneously, reduces manufacturing cost comprehensively, uses wide coverage, technicalization more.

Description

A kind of Miniature safety key

Technical field

The utility model relates to key of anti-theft lock, is specifically related to a kind of Miniature safety key.

Background technology

Chinese utility model patent zl2006200640193 discloses a kind of hinge can 360 degree of theftproof locks rotated freely, this theftproof lock only has a unlock key, if use master key or similar instrument to insert keyhole, at this moment part hinge is in the position of unlocking condition.Due to theftproof lock hinge can 360 degree freely rotate, for the veteran people that unblanks, feel now can be relied on to be rotated further master key or similar instrument rotates to drive hinge, the hinge other being not yet in unlocking condition turns to the state of unblanking by rule of thumb, thus theftproof lock is by technical unlocking, theftproof lock loses antitheft function.The theftproof lock of a locking key is only had too for other structures, the displacement that can move freely due to hinge in the process of unblanking is larger, when insertion master key or similar instrument carry out skilled unlocking, after part hinge is in unlocking condition, be rotated further master key or similar instrument, the blade being then not yet in unlocking condition, because having the larger displacement moved freely, is likely turned to unlocking condition, thus is opened by theftproof lock.In addition, in prior art, some theftproof locks are designed with two unlock key, but, this design often based on the needs improving theftproof lock rigidity and intensity, instead of in order to improve the needs of theftproof performance.

Application number a kind of technical characteristic with claims the 9th article of claims state of the Anti-theft lock head of secondary locking structure that has been the patent disclosure of 201110396513.5: a kind of Anti-theft lock head with secondary locking structure, comprise shell (1), lock core (2), hinge (11), auxiliary unlock key (5) parts, described lock core (2) is arranged in shell (1), several hinges (11) are arranged perpendicular to lock core (2) axis being parallel in lock core (2), described auxiliary unlock key is parallel to lock core (2) axis, it is characterized in that: described hinge (11) has one or two lug (27), the lug grooves (28) that can pass in and out for lug is provided with in the position that shell (1) inwall is corresponding with lug (27), shell (1) inwall is offered with the corresponding part of described auxiliary unlock key (5) the auxiliary groove (22) passed in and out for auxiliary unlock key top, in lock core (2) radial direction, the depth S 3 of lug grooves (28) and width K3 are greater than depth S 2 and the width K2 of auxiliary groove (22) respectively, and the height G3 of lug is then greater than the height G2 of auxiliary unlock key (5), the clearance space angle that the clearance space angle that lug (27) slides in lug grooves (28) is slided in auxiliary groove (22) than auxiliary unlock key (5) is large, can the auxiliary groove (17) of accommodating auxiliary unlock key (5) root in the edge of each hinge (11), one or more restriction groove (23) that auxiliary unlock key root can be made to free in and out is offered in the side of described auxiliary groove (17) or both sides, during locking, lock core (2) is connected with shell (1) by lug (27), auxiliary unlock key (5), when normally unblanking, auxiliary unlock key (5) and lug (27) successively successively order depart from shell (1), auxiliary unlock key (5) first falls into the auxiliary groove (17) of each hinge (11), and lug (27) skids off lug grooves (28) and enters in lock core (2) subsequently.A kind of Miniature key designing technique is provided at this technical the utility model.

a kind of Miniature key utility model content:

The utility model provides a kind of key design technology slightly for above-mentioned technology, provides a kind of Miniature safety key.

The technical solution adopted in the utility model is: a kind of Miniature safety key, comprises handle and key bit, and described handle is connected with key bit; Described key bit is a slab design, on flat board point the upper and lower the first key bit layer and the second key bit layer are set, separate certain distance between levels, described the upper and lower key bit is jagged arrangement.The technical design theory of its entirety is: be merged by two groups of key bits and be designed to the as a whole structure of levels, make the width downsizing greatly of its key, anti-violence is more effective, extends to the volume-diminished of lock core simultaneously, comprehensive reduction manufacturing cost, technicalization more.

Further, described key bit above a direction discernment groove is set, the setting that direction discernment groove is parallel with key bit.

Further, the degree of depth of described direction discernment groove is identical with the thickness of the first key bit layer.

Further, the crown direction of described first key bit layer is contrary to setting with the crown direction of the second key bit layer.

Further, the key bit quantity of described first key bit layer and the key bit quantity of the second key bit layer identical or different.

Further, described first key bit layer is identical with the thickness of handle with the common thickness of the second key bit layer.

Advantage of the present utility model:

The feature of key of the present utility model is that volume is little, and thus the open hole of lockset is little, and unlocking tool is not easy to open.Lock core is little, safety, prevents violence from unblanking.Material is saved, and reduce cost, the variable quantity of key bit is large.The design of two-sided horizontal key bit, matches with theftproof lock, is more conducive to antitheft.

Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
