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

The 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 the conventional door lock, general upper and lower pellet or the blade of adopting of its 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, all be to lock by the blade of difference arrangement and the groove fit of lock core shaft's overcoat, the theftproof performance of its structure design is not strong yet, and fault rate is higher in the use procedure.

Summary of the invention

For the theftproof performance that overcomes common lock core mechanism of door lock in the prior art is weak, the higher problem of fault rate in the 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-ly dials that 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 the lock core shaft's overcoat, a side of key hole is provided with radially sliding lock sheet and the axial sliding lock sheet that matches in lock core shaft; Radially slide in the radial groove of sliding lock sheet in lock core shaft, top, sliding lock sheet upper end compression elasticity spare radially, match with the key of insertion with the inclined-plane in the lower end, the protruding reconciliation draw-in groove of distribution formation fastening up and down on sliding lock sheet radially and side that axially the sliding lock sheet is relative; Axially slide in the axial slide of sliding lock sheet in lock core shaft, axial sliding lock sheet one side top pressure spring, axially match with the key of insertion with pushing face on the sliding lock sheet, axial formation fastening groove on sliding lock sheet and the side that radially the sliding lock sheet is relative, the fastening groove matches with fastening is protruding, form protruding lock dog on the side that axially the sliding lock sheet is relative with the lock core shaft overcoat, protruding lock dog and annular groove on being arranged on lock core shaft's outer sheath inner circumferential surface reach with the crossing locking chute of annular groove and match.

Be provided with steel ball between the elastic component that radially press on sliding lock sheet and upper end top, 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, adopt sliding lock sheet radially and axially the pin mode that matches of sliding lock sheet greatly improved the theftproof performance of lock core, have anti-ly dial that performance is strong, failure rate is low, advantage that reliability is 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 the lock core shaft's overcoat 1,2 of lock core shaft's overcoat 1 and lock core shafts pass through jump ring 20 location, and a side of key hole 3 is provided with radially sliding lock sheet 4 and the axial sliding lock sheet 5 that matches in lock core shaft 2; Radially slide in the radial groove 6 of sliding lock sheet 4 in lock core shaft 2, radially top, sliding lock sheet 4 upper end compression elasticity spare 7, between the elastic component 7 that radially press on sliding lock sheet 4 and upper end top, 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 elastic component 7 general springs that adopt, radially match with the key that inserts with inclined-plane 8 in the lower end of sliding lock sheet 4, and distributing up and down on the relative side of sliding lock sheet 4 radially and axial sliding lock sheet 5 forms the protruding 9 reconciliation draw-in grooves 10 of fastening; Axially slide in the axial slide 11 of sliding lock sheet 5 in lock core shaft 2, axial sliding lock sheet 5 one side top pressure springs 12, axially match with the key that inserts with pushing face 13 on the sliding lock sheet 5, formation fastening groove 14 on the side that axially sliding lock sheet 5 and sliding lock sheet radially 4 are relative, fastening groove 14 matches with fastening protruding 9, form protruding lock dog 15 on the side that axially sliding lock sheet 5 and lock core shaft overcoat 1 are relative, protruding lock dog 15 and annular groove 16 on being arranged on lock core shaft's overcoat 1 inner peripheral surface reach with the crossing locking chute 17 of annular groove 16 and match.When key 21 inserts, other password pellet in the lock core puts in place, the front end of key 21 at first 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 fastening in the sliding lock sheet 4 protruding 9 separates with fastening groove 14 in the axial sliding lock sheet 5, extremely radially the solution draw-in groove 10 in the sliding lock sheet 4 is in same plane with axial sliding lock sheet 5, key 21 continues to insert, the front end of key 21 then pushes the pushing face 13 on the axial sliding lock sheet 5, axially sliding lock sheet 5 overcome spring 12 resistance in axial slide 11 to a Slideslip, axially the protruding lock dog on the sliding lock sheet 5 15 slides in the locking chute 17 on lock core shaft's overcoat 1 inner peripheral surface simultaneously, end during to the crossing position that locks chute 17 and annular groove 16, when key 21 rotates, lock core drives protruding lock dog 15 and enters annular groove 16 and along annular groove 16 rotations, lock unlatching.When key 21 backward rotation put 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 the sliding lock sheet 5 is entering locking chute 17 and is sliding in locking chute 17 under the effect of spring 12, at this moment, lock core can not rotate, axially sliding lock sheet 5 slides into fastening groove 14 and is in same plane with sliding lock sheet 4 radially, key 21 continues to extract, sliding lock sheet 4 down sliding under the effect of elastic component 7 radially, radially the fastening in the sliding lock sheet 4 protruding 9 engages with fastening groove 14 in the axial sliding lock sheet 5, after key 21 is extracted fully, other password pellet in the lock core is all dislocation separation also, finish locking.Above-described embodiment only is that the preferred embodiment to lock core locking mechanism of the present invention is described; be not that design and the scope of inventing limited; under the prerequisite that does not break away from the present invention program; 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.
