Abstract
The utility model relates to an anti-theft linkage lock. The linkage lockset is provided with at least two rotary lock cores, wherein the two rotary lock cores are arranged on wing fans, are close to each other and are provided with extension shafts; in addition, the extension shaft of each lock core is provided with at least one gear and the gears are engaged. The lock can not be simultaneously operated by two people, and one people can not simultaneously operate the two lock cores; accordingly, the lockset has an anti-theft function.
Description
Technical field:
The utility model relates to and a kind ofly is used to be installed on the wing, especially for the theft-proof type blocking lock that is installed on the security door.
Background technology:
Lock is installed usually, to prevent that wing from arbitrarily being opened on the wing of security door or other type.In the prior art, widespread usage lock is by a lock housing and be installed in drum type brake lock cylinder in this lock housing, and is made up of the turning cylinder of lock core control, trace etc., by key bit stir in the lock core pin again rotational lock core just lock can be opened.Yet, because the keyhole of this kind lock is open, after professional unlock staff stirs pin by means of filiform and technological means again rotational lock core just lock can be opened, so this kind lock can not hinder the people who does not grasp key unblanks.For this reason, on the security door that has two or more separate lock cores are installed, to prevent the generation of above-mentioned incident.But because above-mentioned a plurality of lock cores are separate, unlocking person can realize opening the purpose of wing by the mode of opening one by one, so the lock of a plurality of lock cores can only be provided with the time obstacle to unlocking person, can not fundamentally solve antitheft problem.
With regard to the drum type brake cylinder lock, can't come round to the idea key and open it, should be satisfied with two prerequisites, the first must have two manual spaces, and it two is whenever to open a lock core must cooperatively interact in enough spaces by two hands and finish.
Summary of the invention:
The purpose of this utility model provides a kind of little space and linkage manner utilized and prevents to lock the theft-proof type blocking lock of arbitrarily being opened.
The theft-proof type blocking lock that the utility model proposed has at least two of being installed on the wing at a distance of nearer and have the rotatable lock core of outrigger shaft, and on each lock core outrigger shaft at least one pitch wheel is installed.
Gear on the described lock core outrigger shaft has the identical number of teeth and modulus.
Described blocking lock has two adjacent lock housings and is installed in the interior drum type brake lock cylinder of each lock housing.Described lock cylinder is provided with the keyhole of cross or tabular shape.
That connection theft-proof type blocking lock that the utility model proposed adopts two coordinated types and the nearer lock core of being separated by, and the number of teeth the be meshing with each other gear identical with modulus is installed on the outrigger shaft of each lock core, wanting to lock the wing that limits opens, must make two lock cores be in rotating state simultaneously, and two people can't operate in little space, a people can't operate two lock cores again simultaneously, so this kind lockset has anti-theft feature; In addition, this blocking lock just makes its interlock with two lock cylinders by gear, so its cost of manufacture is not high.
Description of drawings:
Accompanying drawing 1 is the cut-away section structural representation of the embodiment of theft-proof type blocking lock that proposes of the utility model.
The specific embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of the embodiment of theft-proof type blocking lock that the utility model proposes.Provide the lock (1 of two linkages in the present embodiment, 2) structure, and each lock (1,2) include two at a distance of nearer lock housings (11,21) be installed in the interior rotatable lock core (12 of lock housing (11,21) respectively, 22), and lock core (12,22) the drum type brake lock cylinder with the keyhole with cross or tabular shape of the prior art is identical basically, so do not provide its concrete structure in the present embodiment.Lock core (12,22) be separately installed with an axial outrigger shaft (13,23), and on each outrigger shaft (13,23), be separately installed with a gear (14,24), and make gear 14 and 24 have the identical number of teeth and modulus, make two gears (14,24) be in intermeshing position when mounted, so that two lock cores (12,22) are realized interlock.
When unblanking, must equivalence earlier two keys be inserted in the keyhole of lock core (12,22), rotate any key then and just this lock can be opened.
