Abstract

The invention relates to a plug-in/out spring lock. A locking/unlocking mode of the spring lock is changed into a translation mode from the present rotation mode; a translation limiting check ring for pushing a lock core spring and a lock cylinder is added; the shape of a key slot is symmetrical; a key is provided with two bits; the bit for opening is matched with a lower spring; a first bit for locking on a locking side is lower than the bit for opening and has a horizontal linear bottom surface; the other bits are the same in two edges; a key handle notch is formed in a key handle part; after the key handle notch is upward and the key is inserted, the lock cylinder is outward translated under an effect of a pushing force for pushing the lock core spring, an unlocking mechanism linked with the lock cylinder is driven, and then the lock is unlocked; when the key handle notch is downward, the key is inserted into the bottom, then the key is pulled out, the lock cylinder is locked by upper and lower springs, and then the lock is locked. The unlocking of the lock requires the outward translation of the lock cylinder and is unrelated to the rotation of the lock cylinder, so that the lock cannot be unlocked by inserting a hard alloy key and forcefully rotating the key. The lock cannot be unlocked by adopting a forcefully unlocking method.

Description

A kind of inserting driven the plug in cylinder lock that closes

Technical field

The present invention relates to a kind of cylinder lock, especially a kind of slotting opening that can prevent that robber from utilizing carbide alloy key to turn on by force lock inserted pass cylinder lock.

Background technology

At present, robber utilizes carbide alloy key to turn on by force locking method to be: first carbide alloy key is inserted in lock core keyhole, then turn round by force and produce destructive rotation, lock has also just been opened, therefore be absolutely unsafe.

Summary of the invention

For the existing cylinder lock of customer service, can with carbide alloy key, turn on by force the deficiency of lock, the invention provides a kind of insert to open to insert close cylinder lock, it can thoroughly stop and with carbide alloy key, applies brute force and unblank, thereby greatly improves degree of safety.

The technical solution adopted for the present invention to solve the technical problems is: the open-close ways of cylinder lock makes existing rotation into translation, increases the pushing lock cylinder spring of pushing lock cylinder translation and the spacing back-up ring of translation of lock core.The spoon groove shape of existing key, by not making symmetry into moving, is made to key is forward and reverse all can be inserted, by wall scroll tartar, make two bar tartars into.It is shorter that first lower pellet made, and plays to extract when sealed in key process, to lock lock core effect.The key operated tartar with one side all matches with lower pellet, and it is horizontal linear shape that sealed sealed the first tartar with one side is made than the low and bottom surface of opening use, and all the other each tartar both sides are identical.In order to differentiate, open and sealed direction, key handle part is provided with the shank of the key breach.In order to increase key intensity, the tartar arrangement position on the key both sides half tooth spacing that misplaces, opens with on one side with spacing flange location, sealed with locating with spacing block set on one side, two location and the tartar half tooth spacing that also misplaces that matches.With above-mentioned key, be as the criterion, the relevant portion of corresponding change lock core and tapered end.

While needing to open this lock, the shank of the key breach upwards, insert key until the end, till making spacing flange encounter lock core end face, now upper and lower pellet all no longer locks lock core, and lock core is under the effect of pushing lock cylinder spring thrust, outwards translation, be subject to marble hole spacing of the spacing back-up ring restriction translation of translation, and the unlocking mechanism of drive and lock core interlock, this locks unlatching.

While needing sealed this lock, the shank of the key breach is downward, insert key the end of up to, till spacing block set is encountered lock core end face, now upper and lower pellet all no longer locks lock core, key overcomes pushing lock cylinder spring thrust to be continued to push away forward, placed restrictions on while stopping by lock core step, because key lock share sealed the first tartar on one side, make than opening the low of use, cause first upper pellet to fall, locking lock core, makes the pushing lock cylinder spring cannot pushing lock cylinder.While extracting key after sealed, sealed the first tartar bottom shape of unifying limit because of key lock is the linearity of level, therefore in an outwards mobile segment distance, first upper and lower pellet position is constant all the time, continue locking lock core, when key, extract position and surpass after a segment distance, other all upper and lower pellets are locked lock core all, and pushing lock cylinder spring is inoperative all the time.When all extracting after key, all upper and lower pellet all locks lock core, and this lock is sealed.

Because of the unlatching of this lock, can need the outside translation of lock core and lock core rotate irrelevant, therefore insert, carbide alloy key is strong to be reversed moving lack scope for their abilitiesly, and the method that this lock cannot be unblanked by brute force is opened.

The invention has the beneficial effects as follows: can thoroughly stop to turn on by force lock with carbide alloy key, theftproof performance is good, and simple and reliable for structure, easy to use.

The specific embodiment

In Fig. 1～Fig. 4, the mode of translation before and after the folding of this lock adopts, the pushing lock cylinder spring 3 of increase pushing lock cylinder 2 translations, the spacing back-up ring 4 of translation of control lock core 2 translation spacing.It is shorter that first lower pellet 6 made, and plays to extract when sealed in key 7 processes, to lock lock core 2 effects.The shape of 7 spoons of grooves of key is symmetrical, make that key 7 is forward and reverse all can be inserted, key 7 has two tartars, open with tartar on one side and all match with lower pellet, it is the linearity of level that sealed sealed the first tartar 7d with one side makes than low 1 millimeter and the bottom surface of opening use, and all the other each tartar both sides are identical.In order to differentiate, open and sealed direction, key 7 shanks are provided with the shank of the key breach 7a.In order to increase key 7 intensity, the arrangement position of the key 7 both sides tartars half tooth spacing that misplaces, opens with on one side with spacing flange 7b location, sealed with locating with spacing block set 7c on one side, two location and the tartar half tooth spacing that also misplaces that matches.The above-mentioned key 7 of take is benchmark, the relevant portion of corresponding change lock core 2 and tapered end 1.

In Fig. 1, while needing to open this lock, the shank of the key breach 7a upwards, inserts key 7 until the end, till making spacing flange 7b encounter lock core 2 end faces, now upper and lower pellet all no longer locks lock core 2, and in Fig. 2, lock core 2 is under pushing lock cylinder spring 3 thrust, outwards translation, be subject to marble hole spacing of the spacing back-up ring 4 restriction translations of translation, and the unlocking mechanism (do not belong in partial graph of the present invention and do not omit and do not draw) of drive and lock core 2 interlocks, this locks unlatching.

In Fig. 3, while needing sealed this lock, 7a is downward for the shank of the key breach, insert key 7 until the end, till spacing block set 7c encounters lock core 2 ends, now upper and lower pellet all no longer locks lock core 2, in Fig. 4, key 7 overcomes pushing lock cylinder spring 3 thrusts to be continued to push away forward, while stopped by lock core step 2a restriction, because key lock share sealed the first tartar 7d on one side, make than low 1 millimeter of opening use, cause first upper pellet 5 to fall, locking lock core 2, makes the pushing lock cylinder spring 3 cannot pushing lock cylinder 2.While extracting key 7 after sealed, because key lock share sealed the first tartar 7d bottom shape on one side, it is the linearity of level, therefore in an outwards mobile segment distance, the position of first lower pellet 6 and first upper pellet 5 is constant all the time, continue locking lock core 2, when key 7, extract position and surpass after a segment distance, other all upper and lower pellets are locked lock core 2 all, and pushing lock cylinder spring 3 is inoperative all the time.After all extracting key 7, all upper and lower pellet all locks lock core 2, and this lock is sealed.

Because of the unlatching of this lock, can need the outside translation of lock core 2 and lock core 2 rotate irrelevant, therefore insert, carbide alloy key is strong to be reversed moving lack scope for their abilitiesly, and the method that this lock cannot be unblanked by brute force is opened.
