Abstract

The utility model relates to a pushing key coded lock which belongs to the technical field of a mechanical coded lock, comprising a lock body, a lock core, and a lock box. The utility model is characterized in that the lock core is provided with a disc with balls; eight pinholes which correspond to the pinholes on the disc are distributed on the inner of the lock core; the pinholes in the lock core are provided with slices which are cylinder-shaped, the slices are provided with notches and buckled with outer sleeves; each slice is covered with a spring; only when all the breaches of the slices are at a horizontal position, all the projection points of the outer sleeve of the slices are at the position of the breaches, the lock core can be rotated. The utility model has the advantages of unique structure, good performance of proofing, firmness and durability.

Description

Pushing key coded lock

The utility model belongs to the mechanical code lock technical field.

What be widely used at present is mechanism's lock, and its structure is made of lock body, lock core and rotor, and inside and outside pellet shot from a slingshot is housed in lock core, is added with compression spring in the pellet shot from a slingshot outside, because the uneven in length dislocation of pellet shot from a slingshot makes rotor rotation, and the unlatching that decision is locked.Advantage be simple in structure, produce easily, its shortcoming is that all mechanical lock structures are identical substantially, key shape is similar, confidentiality is poor, the pick-proof poor performance is so it is bad to take precautions against effect.

For solving the deficiency of above mechanism lock construction, it is the mechanical lock of lock core structure with the page or leaf sheet that the utility model provides a kind of, the depression breach of utilization page or leaf sheet cooperatively interacts with page protruding point of sheet block and determines the rotation of lock core, be added with the garden mast key of many combinations again, effectively solve the problem that general mechanism lock is opened easily, thereby reached the purpose of safety precaution.

Structure of the present utility model is design like this: a columniform lock core (as shown in Figure 1) is housed in the lock body of a circle, a disk is equipped with near in the key mouth of lock body in outside at lock core, disk perimeter is eight apertures of distribution evenly, in each aperture, be placed with a ball, eight apertures are corresponding with uneven in length cylindrical bar on the key, same eight apertures that distribute in the lock core surrounding, corresponding with aperture on the disk, a page or leaf sheet is housed in each aperture of lock core, the page or leaf sheet is cylindrical, diverse location has a translot on each cylindricality page or leaf sheet, ball on the dish of one end and garden pushes up mutually, the other end is with a spring on each cylinder, be buckled with a page sheet overcoat in page or leaf sheet outside, the overcoat top has convex-concave breach (as shown in Figure 4), the corresponding page or leaf sheet of each recess, forward there is a keyway overcoat outside, fix with pin key and lock body, in key stretches into lock body, the depression breach of all eight page or leaf sheets and the convex-concave breach of overcoat are on a horizontal plane, lock core is just rotatable, page or leaf sheet and page or leaf sheet overcoat are the cores of this device, at all spring capping is housed above the spring, have equally on the gland eight with the corresponding aperture in page or leaf sheet upper end, aperture is half groove, wherein page or leaf sheet end can be passed, and spring can not pass through, the outside of lock core is a sleeve, just be buckled on the gland, the sleeve bottom center has a garden mouth, and the plectrum on the lock core stretches out from round mouth, have forward keyway in the sleeve both sides, corresponding with circle both sides keyway in the lock body, lock body and sleeve are become one after fixing with locking key, and lock core can only rotate in the sleeve of lock body.Its course of work: key is a disc, eight uneven in length cylindrical bars are vertically arranged on disk, insert from the key mouth of lock body, eight balls corresponding to cylindrical bar move down respectively, the ball back is the page or leaf sheet, below the page or leaf sheet is spring, there is the spring pressure cap spring outside, each page sheet moves down along with moving down of ball in the aperture of oneself, the convex-concave breach that has when the depression breach of all pages sheet and page or leaf sheet overcoat top is on a horizontal plane, and lock core could rotate, and each lock core has only so a kind of combination, lock core rotates and drives the plectrum rotation, the lock state of being out.

Advantage of the present utility model: the lock core structure uniqueness, adopt the page or leaf sheet to make snap, strong security, the pick-proof performance is good, and is safe and reliable, and the life-span is long, and is easy to install.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.
