Description

With protecting cover lock

Technical field

The utility model relates to a kind of lockset, more particularly, relates in particular to a kind of with protecting cover lock.

Background technology

Along with improving constantly of economy and human living standard, people's antitheft consciousness and facility also should improve and improve.Undeniable, the case of China and even whole world burglary happens occasionally at present.My neighbours, relatives and friends also had the experience of being forced open the door by thief's picking lock, and medium also have report often.So people just buy the high lockset of some antitheft coefficients by every means, like double hoodle, idle running lock, magnetic strength lock, crescent lock ... Deng, but these locksets all have a common weakness: keyhole exposes.Through the analysis of some cases, the trick that the thief habitually practises is nothing but 1. technology unlockings.2. turn round mashed lock core by force.3. tinfoil is unblanked.Sum up, as long as keyhole exposes, and leave sufficient space, instrument just gets into lockset easily, just might lockset be opened.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, provides a kind of simple and reasonable for structure, easy to use and respond well with protecting cover lock.

The technical scheme of the utility model is achieved in that a kind of with protecting cover lock; Comprise lock core; On lock core, be provided with lockhole; Wherein said lockhole periphery is provided with protective cover, on the sidewall of protective cover near lockhole, is provided with through hole, on through hole, is movably set with the key that matches with lockhole.

In the above-mentioned with protecting cover lock, described through hole is made up of the horizontal slotted hole that is interconnected and vertical slotted hole, and laterally slotted hole cooperates L-shaped with vertical slotted hole; Described key is made up of spoon body, the shank of the key and spoon bar, and spoon bar two ends are connected with the shank of the key with the spoon body respectively, and spoon body, the shank of the key and spoon bar cooperate and be Z-shaped.

After the utility model adopts said structure, through protective cover is set outside lock core, simultaneously with key design become to match with protective cover Z-shaped.Compared with prior art, have following advantage:

(1) locksmith's instrument is difficult to get into lockhole, even if entering does not have spatial operation yet reluctantly.

(2) because L type keyhole and Z type key design for close-fitting, and width should be about 2-3mm, make the tool that goes into operation by force be difficult to get into, even if entering also will be arrived the top reluctantly, just can pull rotation, so thin instrument can't be opened lock by force.
