Abstract

The invention discloses a double-tube storehouse lock, which consists of an elastic lock beam (1), a lock beam spring (2), a lock body (3), a bolt spring (4), a lock beam bolt pin (6) and a primary lock core (8), and is characterized in that: the middle part of one side of the primary lock core (8) is movably connected with the middle part of a secondary lock core (7); and the secondary lock core (7) is fixedly connected with the big face of the lock body (3). Thus, the lock is very safe and has high antitheft performance, high internal transparency, good use effect and high protection capacity, and therefore is particularly suitable to be used as a lock for a storehouse of valuables, a storehouse for dangerous objects or a safe.

Description

Two-tube storehouse lock

Technical field:

The present invention relates to a kind of lockset, particularly a kind of two-tube storehouse lock.

Background technology:

Common on the market at present padlock is all opened different locks with different keys, if key is lost or is grasped by the someone, safety so, protective just greatly reduces, the people of this key provides the chance that satisfies individual interest to only having, and the not anti-function of dialling of common padlock pellet shot from a slingshot, the safe antitheft of lockset is lower, the place that some are important, as various valuables storehouses, dangerous material storehouse and various strongbox, cabinets etc. require safety, theftproof, the place of internal openness all can be used two or many common padlock at present simultaneously, to improve safety and publicity, this kind way is corresponding can to produce some side effects, as: must there be two or more snap closes simultaneously in the place that requires to lock, the restriction of cost and aspect, space result of use is had a greatly reduced quality, and safe antitheft is relatively poor, lock need be opened one by one, result of use is undesirable.

Summary of the invention:

The purpose of this invention is to provide two lock core co-operation of a kind of use, safe antitheft height, the two-tube storehouse lock that result of use is good.

The object of the present invention is achieved like this: a kind of two-tube storehouse lock, form by elasticity lock bridge, lock bridge spring, lock body, bolt spring, lock bridge latching, main lock core, it is characterized in that the middle part of a side of described main lock core and the middle part of auxiliary lock core flexibly connect, auxiliary lock core is fixedlyed connected with the big face of described lock body.

An optimum implementation of the present invention is: main lock core and auxiliary lock core respectively have an arc groove, and two arc grooves coincide mutually.

The present invention compared with prior art has the following advantages:

Owing to the middle part of a side that has adopted main lock core and the middle part flexible connection of auxiliary lock core, the form of structure that auxiliary lock core is fixedlyed connected with the big face of described lock body, thereby, complete opening and close two people that need have key and open locking simultaneously and could normal use, improved safe antitheft, internal openness, result of use greatly, protective capacities is strong.

6, lock bridge latching 7, auxiliary lock core 8, main lock core 9, master key

10, auxiliary lock core key 11, auxiliary lock core arc groove 12, main lock core arc groove

The specific embodiment:

Elasticity lock bridge 1, lock bridge spring 2, lock body 3, bolt spring 4, lock bridge latching 6, main lock core 8, main lock core key 9 adopt the form of structure of the common padlock of selling on the market at present, different is the arc groove 12 of side processing that does not have the face of pellet shot from a slingshot at main lock core 8, the middle part of one side of main lock core 8 and the middle part of auxiliary lock core 7 flexibly connect, auxiliary lock core 7 is fixedlyed connected with the big face of lock body 3, main lock core 8 respectively has an arc groove 11, two arc grooves 12 to coincide mutually with auxiliary lock core 7

During use, during unlatching, earlier auxiliary lock core key 10 is inserted in the auxiliary lock core 7, revolute lock core key 10, this moment, the auxiliary lock core upper groove slided to the groove of main lock core under the drive of auxiliary lock core, and two grooves well coincide and create the path of main lock core rotation, again main lock core key 9 is inserted in the main lock core 8, rotation main lock core key 9, elasticity lock bridge 1 ejects from lock body 3, has finished breakdown action; During locking, earlier elasticity lock bridge 1 is inserted in the lock body 3, then main lock core key 9 is extracted, revolute lock core key 10, this moment, the auxiliary lock core groove skidded off original position under lock core drives, and the auxiliary lock core groove separates with the main lock core groove, and auxiliary lock core is with the main lock core locking, main lock core key 9 can't insert main lock core 8 at this moment, can't open elasticity lock bridge 1.

When master's lock locking, secondary lock pin groove is in opening, and this moment, secondary lock was inoperative, but when main lock locking and pair locking, main lock can operate as normal but secondary lock key then can't pull up and in time warn this two-tube storehouse to lock complete locking, fail to reach best safe antitheft state.

Secondary lock need insert key behind main lock locking, under the drive of lock core, the auxiliary lock core groove slides into the main lock core groove and separates, auxiliary lock core do not have the groove side with the main lock core groove identical after with the main lock core locking, main lock core can't insert key 9.Main lock, secondary lock must earlier with secondary lock key be opened pair lock respectively with a key (two) totally, and master's lock could complete opening and locking.
