Abstract
The present invention relates to a built-in lock core push type spring lock which is a universal lockset, and the present invention belongs to the field of a mechanical spring lock. An exerted lock core is improved into a built-in lock core, a mode that the lock is unlocked by rotating the lock core is improved into a mode that the lock is unlocked by pushing the lock core, and a key opening with a width of 2 millimeters is improved into a narrow slit of which the width is less than 1 millimeter; thus, the present invention greatly improves the prying-preventing capability of the spring lock, and solves the problem that the existing spring lock is easy to pry. The present invention has the characteristics of simple structure, easy manufacture and convenient production of the existing manufacturing plant.
Description
(1) technical field:
The present invention is a kind of cylinder lock, is mechanical general lockset, belongs to the cylinder lock technical field.
(2) background technology:
Cylinder lock is present most popular mechanical lockset.Various door locks, bicycle lock, electronic lock, lock for motorcycle, Automotive lock etc. are made with various cylinder locks mostly, and consumption is very huge.The frame mode that present most employing key rotation lock core is unblanked, lock core exposes, and is easy to be pried open by flat mouth or the stubborn by force lock core of cross mouth robber tool insertion key.
(3) summary of the invention:
Purpose of the present invention is exactly the deficiency of being prized easily at existing cylinder lock, a kind of built-in lock pin is provided, promotes the cylinder lock that lock core is unblanked, difficult quilt is prized with key.
Built-in lock pin type push form cylinder lock of the present invention mainly comprises tapered end, lock core cover, dead bolt, upper lock core, following lock core, dead bolt spring, return spring, key, plug etc.Wherein, the lock core that upper lock core and following lock core are formed places the lock core cover, and upper lock core is fixing with screw and lock core cover, and following lock core can slide in the lock core cover, lock core cover rear end rear end cap press seal, and front end drive end bearing bracket press seal, dead bolt can stretch out from the hole of drive end bearing bracket.The front end of upper lock core is milled with step, and the front end of following lock core is milled with the breach of band rib, and dead bolt can slide in the synthetic groove of step and breach.When plug inserted, dead bolt slided backward.After plug inserted and puts in place, dead bolt skidded off under the effect of dead bolt spring force plug is pinned.Key bit is built in the top of key, and the key mouth from the tapered end side when unblanking inserts, and the latasuture through the lock core cover is inserted into down in the key of lock core, makes the pellet shot from a slingshot release.At this moment can promote down lock core, the rib of following lock core moves after driving dead bolt, discharges plug, and lock has just been opened.After decontroling or extracting key, following lock core can reset under the effect of return spring.When shutting, plug inserts, and dead bolt moves after the meeting, and after plug put in place, dead bolt stretched out under the effect of dead bolt spring force, and plug is pinned.Because key is to promote lock core rather than rotational lock core, so can make key with very thin material.The width of the latasuture of key mouth, lock core cover and the key of following lock core can be below 1 millimeter.Can prevent the insertion that flat mouth or cross mouth are stolen tool.Promptly use the thin slice below 1 millimeter to steal the tool insertion, its intensity can not make down lock core move by force and pry open.
Adopt built-in lock pin type push form cylinder lock of the present invention, its advantage is that built-in lock pin, key mouth are very narrow, and flat mouthful of general rotation or cross mouth are stolen tool and can't be prized, and thin slice is stolen tool and prized not open again, so improved the pick-proof performance of cylinder lock greatly.
(4) description of drawings:
Figure (1) is a sectional drawing of the present invention.Key 8 has inserted in the tapered end 1, pellet shot from a slingshot 11 release.As long as promote key 8 to the right, following lock core 5 just can drive dead bolt 3 and move to right, and discharges plug 9 and unblanks.
Figure (2) is a perspective view of the present invention.
Figure (3) is the three-dimensional appearance schematic diagram of tapered end 1 of the present invention, key 8, plug 9.
(5) specific embodiment:
The present invention is that the embodiment of example is a upper lock core 4 and following lock core 5 lock core of packing into overlaps 2 with the hawser lock, and following lock core 5 should be able to easily slide.Lock core cover 2 usefulness drive end bearing bracket 2-2, rear end cap 2-1 press seal.Dead bolt 3 can slide in the synthetic groove of step 4-1 and breach 5-1.When dead bolt 3 stretches out the hole 2-3 of drive end bearing bracket 2-2 under the elastic force effect of dead bolt spring 6 and return spring 7, should be able to pin plug 9.The distance of sliding in groove should be able to guarantee the insertion of plug 9.When the dead bolt 3 of the rib 5-2 of lock core 5 drive instantly moved to right, mobile distance should guarantee that dead bolt 3 can discharge plug 9, again can not be greater than 2/3rds of 2 row pellets shot from a slingshot, 11 spacings.When spacer 10 inserts key mouth 1-1 at key 8, play the location and import.The lock core that assembles is enclosed tapered end 1 at last.Key 8 makes pellet shot from a slingshot 11 releases in the latasuture 2-4 of the key mouth 1-1 of tapered end 1, lock core cover 2 is inserted into down the key 5-3 of lock core 5.According to the above, just can form built-in lock pin driving cylinder lock of the present invention.
