Abstract

The invention relates to a double-opening spring lock, comprising a lock shell (1) and lock cylinders (2) symmetrically arranged in the lock shell (1) bilaterally, wherein a driving wheel (8) is arranged in the middle of the lock shell; transmission parts (10) are symmetrically arranged on two sides of the driving wheel (8); a groove (10.1) matched with a boss (8.1) of the driving wheel (8) is formed on one end surface of each transmission part (10); the bottom of the groove (10.1) contacts a return spring (9); a clamping groove (10.2) is formed in the middle of the other end surface of the transmission part (10) in a radial direction; the clamping groove (10.2) is matched with a head of a key (11). The double-opening spring lock achieves an unlocking function at two sides of the lock simultaneously by reasonable improvement of a structure, and the problem that the other side of the existing lock cannot be unlocked while someone forgets to pull out the key inserted into a lock cylinder hole on one side is solved.

Description

Two cylinder locks of opening
Technical field
The present invention relates to a kind of lockset, relate to two cylinder locks of opening that a kind of two can be opened lock simultaneously.
Background technology
The cylinder lock that is installed in the door is made up of lock shell and two transversely arranged lock cores usually, between two lock cores, all links to each other with trackwheel through driving member.When key insertion keyhole puts in place, key will be gone up pellet shot from a slingshot and just in time eject lock core marble hole, simultaneously driving member pushed to the lock core of another side.At this moment, turn key cylinder and just can rotate, drive driving member simultaneously, stir dead bolt by driving member drive trackwheel again lock is opened.Such action is in door, all can accomplish outdoors.Therefore, door is inside and outside all can turn lock core and lock is opened.But forgotten to pull out in the lock core hole in the people is inserted in key at door, and the people even also having an adaptive key, this person also is difficult to from opening this lock outdoors when outdoor.Its reason is: that key in the door is pushed lock core oneself driving member on one side to other end, and when inserting key again, key is withstood by own driving member on one side in the other end of lock core hole and can not put in place when inside and outside, causes can't opening.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of two cylinder lock of opening is provided, can will lock unlatching at lock two simultaneously, prevent the situation that door can't be opened.
The objective of the invention is to realize like this: a kind of two cylinder locks of opening; It comprises the lock shell and is symmetrical set the lock core in the lock shell, in the pellet shot from a slingshot hole of said lock shell, is provided with from top to bottom and seals pellet shot from a slingshot, pellet shot from a slingshot spring and tack pellet shot from a slingshot, in the pellet shot from a slingshot hole of said lock core, is provided with the round end pellet shot from a slingshot; The position of said round end pellet shot from a slingshot is corresponding one by one with the position of tack pellet shot from a slingshot; Middle part at said lock core has keyhole, is provided with thumb wheel at the middle part of said lock shell, on the two sides of said thumb wheel, is provided with boss; Be provided with the returning spring that runs through thumb wheel and both sides boss at the middle part of said thumb wheel; Both sides at said thumb wheel are symmetrically arranged with driving member, have the groove that matches with boss on the end face of said driving member, and the bottom of said groove contacts with returning spring; Middle part, other end at said driving member radially has draw-in groove, and said draw-in groove matches with the head of key.
Said tack pellet shot from a slingshot can use I-shaped tack pellet shot from a slingshot to substitute.
Be symmetrically arranged with the anti-drilling steel pin parallel with the pellet shot from a slingshot hole at the two ends of said lock shell.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention improves through Rational structure, has realized the function that can unblank simultaneously in the lock both sides, has solved existing lock and has forgotten to pull out the shortcoming that opposite side can't be unblanked because of there being the people key to be inserted in the lock core hole of a side.

The specific embodiment
Referring to Fig. 1-Fig. 4, the present invention relates to a kind of two cylinder lock of opening, mainly form by the lock core 2 of locking shell 1 and be symmetrical set in lock shell 1.In the pellet shot from a slingshot hole of lock shell 1, be provided with from top to bottom and seal pellet shot from a slingshot 3, pellet shot from a slingshot spring 4 and tack pellet shot from a slingshot 5; Wherein in two pellet shot from a slingshot holes, tack pellet shot from a slingshot 5 usefulness I-shaped flat noses 6 is replaced in order to guard against theft; Said seal that pellet shot from a slingshot 3 is arranged in the lock shell 1 and with the end face of lock shell 1; Play the effect of sealing, in the pellet shot from a slingshot hole of lock core 2, be provided with round end pellet shot from a slingshot 7, the position of said round end pellet shot from a slingshot 7 is corresponding one by one with the position of tack pellet shot from a slingshot 5; Be provided with U type thumb wheel groove 1.1 at the middle part of said lock shell 1; In thumb wheel groove 1.1, be provided with thumb wheel 8; On the two sides of said thumb wheel 8, be provided with boss 8.1, be provided with the through hole that runs through thumb wheel 8 and both sides boss 8.1 at the middle part of said thumb wheel 8, in through hole, be provided with returning spring 9; Be symmetrically arranged with driving member 10 on the both sides of said thumb wheel 8; Have the groove 10.1 that matches with boss 8.1 on one end face of said driving member 10, the bottom of groove 10.1 contacts with returning spring 9, radially has draw-in groove 10.2 at the middle part, other end of driving member 10; Said draw-in groove 10.2 matches with the head of key 11, guarantees under the situation that key 11 rotates a circle that once chance and driving member 10 are blocked; Have keyhole 12 at the middle part of said lock core 2; Key 11 inserts lock core 1 by keyhole 12 and contacts with driving member 10, and rotation after the head of key 11 snaps in draw-in groove 10.2 can drive thumb wheels 8 rotations by driving member 10; Thereby can in one direction lock be opened; And another direction adopts same structure, and no matter whether the key of relative direction inserts in the draw-in groove 10.2, and other direction all can be implemented unlock operation.
Be symmetrically arranged with the anti-drilling steel pin 13 parallel at the two ends of said lock shell 1, prevent that the lawless person from will lock by force through drill bit mode of perforate on the lock shell to open with the pellet shot from a slingshot hole.
