Abstract

The invention relates to a cylinder locking mechanism. A radial sliding lock plate and an axial sliding lock plate matching with each other are arranged on a cylinder shaft. An elastic member is abutted to the upper end of the radial sliding lock plate, and the slanted lower end of the radial sliding lock plate matches with an inserted key. A locking projection and an unlocking groove are arranged on the upper and lower portions of the side, facing to the axial sliding lock plate, of the radial sliding lock plate. One side of the axial sliding lock plate abuts to a spring. The axial sliding lock plate is provided with a push face matching with the inserted key. A locking groove is formed on the side, facing to the radial sliding lock plate, of the axial sliding lock plate and matches with the locking projection. A raised lock block is formed on the side, facing to an outer sleeve of the cylinder shaft, of the axial sliding lock plate. The raised lock block matches a circular groove on the inner periphery of the outer sleeve of the cylinder shaft and a locking slide intersecting with the circular groove. The defect that the existing cylinder mechanism is poor in burglary prevention is overcome. The coding way that the radial sliding lock plate matches with the axial sliding lock plate enhances burglary prevention of the cylinder, and the cylinder locking mechanism has the advantages of high turning proofing, low failure rate and high reliability.

Description

Lock core locking mechanism

Technical field

The present invention relates to a kind of lock core locking mechanism.

Background technology

Lock core locking mechanism in conventional door lock, its general upper and lower pellet or the blade of adopting of Cipher mechanism, wherein the structure design of upper and lower pellet is simpler and cruder, theftproof performance a little less than, and adopt blade as the lock core of Cipher mechanism, be all that the blade arranged by difference and the groove fit of lock core shaft's overcoat lock, the theftproof performance of its structure design is not strong yet, and in use procedure, fault rate is higher.

Summary of the invention

The higher problem of fault rate for the theftproof performance that overcomes common lock core mechanism of door lock in prior art is weak, in use procedure, the invention provides a kind of lock core locking mechanism, the unlock operation of this lock core locking mechanism is convenient, antitheft anti-dial performance is strong, failure rate is low, reliability are strong.

The technical solution adopted for the present invention to solve the technical problems is: comprise the lock core shaft in lock core shaft's overcoat and lock core shaft's overcoat, in lock core shaft, a side of key hole is provided with radially sliding lock sheet and the axial sliding lock sheet matching; Radially in the radial groove in sliding lock Pian lock core shaft, slide, top, sliding lock sheet upper end compression elasticity part radially, matching with the key of insertion with inclined-plane in lower end, at sliding lock sheet radially, forms the protruding reconciliation draw-in groove of engaging with distributing up and down on side that axially sliding lock sheet is relative; Axially in the axial slide in sliding lock Pian lock core shaft, slide, axial sliding lock sheet one side top pressure spring, axially on sliding lock sheet, with pushing face, match with the key of insertion, axially sliding lock sheet forms engaging groove with on side that radially sliding lock sheet is relative, engaging groove matches with engaging is protruding, on the side that axially sliding lock Pian Yu lock core shaft overcoat is relative, form protruding lock dog, protruding lock dog be arranged on annular groove in lock core shaft's outer sheath inner circumferential surface and the locking chute crossing with annular groove and match.

Between the elastic component that radially press on sliding lock sheet and top, upper end, be provided with steel ball, elastic component and steel ball are arranged in the slotted eye of lock core shaft's overcoat.

The present invention is by above-mentioned specific design, adopts sliding lock sheet radially and pin mode that axially sliding lock sheet matches greatly to improve the theftproof performance of lock core, has advantages of that anti-dial performance is strong, failure rate is low, reliability be strong.

The specific embodiment

As shown in the figure, the present invention includes the lock core shaft 2 in lock core shaft's overcoat 1 and lock core shaft's overcoat 1,2 of lock core shaft's overcoat 1 and lock core shafts locate by jump ring 20, and in lock core shaft 2, a side of key hole 3 is provided with radially sliding lock sheet 4 and the axial sliding lock sheet 5 matching; Radially in the radial groove 6 of sliding lock sheet 4 in lock core shaft 2, slide, sliding lock sheet 4 top, upper end compression elasticity parts 7 radially, between the elastic component 7 that radially press on sliding lock sheet 4 and top, upper end, be provided with steel ball 18, elastic component 7 and steel ball 18 are arranged in the slotted eye 19 of lock core shaft's overcoat 1, the general spring that adopts of elastic component 7, radially match with the key inserting with inclined-plane 8 in the lower end of sliding lock sheet 4, distributes up and down and form the protruding 9 reconciliation draw-in grooves 10 of engaging on the side that radially sliding lock sheet 4 is relative with axial sliding lock sheet 5; Axially in the axial slide 11 of sliding lock sheet 5 in lock core shaft 2, slide, axial sliding lock sheet 5 one side top pressure springs 12, axially on sliding lock sheet 5, with pushing face 13, match with the key inserting, axially sliding lock sheet 5 forms engaging groove 14 with on side that radially sliding lock sheet 4 is relative, engaging groove 14 matches with engaging protruding 9, on the side that axially sliding lock sheet 5 is relative with lock core shaft overcoat 1, form protruding lock dog 15, protruding lock dog 15 be arranged on annular groove 16 on lock core shaft's overcoat 1 inner peripheral surface and the locking chute 17 crossing with annular groove 16 and match.When key 21 inserts, other password pellet in lock core puts in place, first the front end of key 21 pushes the radially inclined-plane 8 of sliding lock sheet 4, make sliding lock sheet 4 radially overcome resistance upward sliding in radial groove 6 of elastic component 7, radially the engaging in sliding lock sheet 4 protruding 9 is separated with the engaging groove 14 in axial sliding lock sheet 5, extremely radially the solution draw-in groove 10 in sliding lock sheet 4 and axial sliding lock sheet 5 are in same plane, key 21 continues to insert, the front end of key 21 then pushes the pushing face 13 on axial sliding lock sheet 5, the resistance that axially sliding lock sheet 5 overcomes spring 12 in axial slide 11 to a Slideslip, axially the protruding lock dog on sliding lock sheet 5 15 slides in the locking chute 17 on lock core shaft's overcoat 1 inner peripheral surface simultaneously, to lock chute 17 and annular groove 16 crossing position time only, when key 21 rotates, lock core drives protruding lock dog 15 to enter annular groove 16 and rotates along annular groove 16, lock is opened.Key 21 rotates backward while putting in place, protruding lock dog 15 comes back to annular groove 16 and the crossing position that locks chute 17, when key 21 is extracted, axially the protruding lock dog 15 on sliding lock sheet 5 enters locking chute 17 and slides in locking chute 17 under the effect of spring 12, now, lock core can not rotate, axially sliding lock sheet 5 slide into engaging groove 14 with sliding lock sheet 4 radially in same plane, key 21 continues to extract, sliding lock sheet 4 down sliding under the effect of elastic component 7 radially, radially the engaging in sliding lock sheet 4 protruding 9 engages with the engaging groove 14 in axial sliding lock sheet 5, after key 21 is extracted completely, also all dislocation is separated for other password pellet in lock core, complete locking.Above-described embodiment is described the preferred embodiment of lock core locking mechanism of the present invention; not design and the scope of invention are limited; do not departing under the present invention program's prerequisite; various external form modification and improvement that those skilled in the art make technical scheme of the present invention, all should fall into the protection domain of lock core locking mechanism of the present invention.
