Background technology
At present, what lock core mostly adopted is the billiards structure of arranging up and down, when opening, applies a revolving force to lock gall by using key, keeps to the side after making the pellet pressurized, and when all hoodles were in same plane, lock core can be opened.Because can only reducing by the quantity that increases arrangement or pellet and inserted sheet, each pellet or inserted sheet open mutually probability, and key all is to move by overcoming the spring resistance that acts on spring or inserted sheet, no matter spring more tiny its key that also can't change must overcome the direct resistance of spring and pass in and out movement, this is so that the plug feel of key is directly felt the resistance of spring, and its strength of using is on hand also arranged and increased and strengthen along with pellet.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, theftproof performance is high, plug resistance little lock core.
A kind of lock core comprises lock core shell and places the interior lock gall of lock core shell that described lock gall can rotate and have the keyhole with the key insert port in described lock core shell; Be provided with the lock gall unimodule that several are arranged in order in the described lock gall, described lock gall unimodule is by lock gall string sheet, lock gall inserted sheet and clockwork spring consist of, described lock gall string sheet middle part offers keyhole, these keyhole both sides are respectively equipped with alignment pin and lever pin, described lock gall inserted sheet is set on this lever pin, and has the degree of freedom of rotating around lever pin, this sheathed end place is provided with and drives the elastomeric element that the lock gall inserted sheet rotates, described lock gall inserted sheet is provided with extended lock gall string sheet and can supports the locking card base be located on the alignment pin, can stir card base with the key insertion end touches mutually in addition.
Described lock gall two ends are provided with lock gall anter and lock gall cauda, and the described lock gall unimodule that several are arranged in order is located in the alignment pin on the lock gall anter, and fastening by the lock gall cauda.
The key insertion end surface of described lock gall anter is provided with the ball hole.
The described lock gall cauda other end is provided with can be around the connecting rod of its rotation, and this connecting rod is provided with can the corresponding draw-in groove that touches with key.
The described connecting rod other end is provided with pad and interior jump ring.
Also be provided with the middle part locking card base that plays balanced action on the described lock gall inserted sheet between the locking card base.
Described elastomeric element is stainless steel spring.
The utility model adopts independently lock gall unimodule formation lock gall, can adjust as required quantity and the phase place of lock gall unimodule, realizes the multiple combination mode, has improved greatly anti-theft capability.And utilized the clockwork spring principle of clock and watch, poor by the arm of force of special-shaped lock gall inserted sheet, utilize the leverage when opening, reduced significantly the plug resistance of key, make the key plug smooth especially.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of lock gall unimodule in the utility model.
Fig. 3, Fig. 4 are the positive antiphase schematic diagram of lock gall inserted sheet in the utility model.
The specific embodiment
Referring to Fig. 1, a kind of lock core that the utility model provides, comprise lock core shell 1 and place lock gall 2 in the lock core shell 1, described lock gall 2 can rotate and have the keyhole 4 with key 3 insert ports in described lock core shell 1, described lock gall 2 is by being arranged in order lock gall anter 2a, several lock gall unimodules 2b, lock gall cauda 2c, connecting rod 2d, pad 2e and interior jump ring circle 2f consist of, described several lock gall unimodules 2b is located on the alignment pin 2g of lock gall anter 2a, 2c is fixed into one by the lock gall cauda, described connecting rod 2d is fastened on lock gall cauda 2c opposite side, the one end be provided with can with the key 3 corresponding draw-in groove 2d-1 that touch, pad 2e and interior jump ring circle 2f are fixed on the contact surface of lock gall cauda 2c surface and connecting rod 2d.
Lock gall unimodule 2b is made of lock gall string sheet 2b-1, lock gall inserted sheet 2b-2 and clockwork spring 2b-3.
Referring to Fig. 2,
Described lock gall string sheet 2b-1, in the form of annular discs, key 3 passes from the keyhole that is arranged in lock gall string sheet 2b-1 middle part, alignment pin 2g on the lock gall anter 2a passes from the dowel hole that is arranged in lock gall string sheet 2b-1 side, also be provided with lever pin 2b-1-1 on described another side of lock gall string sheet 2b-1, lock gall inserted sheet 2b-2 is set on this lever pin 2b-1-1, and has the degree of freedom around lever pin 2b-1-1 rotation.Described lock gall inserted sheet 2b-2 is provided with top locking card base I 2b-2-1, middle part locking card base II 2b-2-2, the afterbody locking card base III 2b-2-3 at lock gall string sheet 2b-1 circumferential edge place, and the keyhole place stir card base 2b-2-4.
