Abstract

The utility model discloses a marble idling locking head comprising a shell, a front locking core, a rear locking core, and marbles and the like, wherein the front locking core and the rear locking core are sheathed in the shell; the front locking core is longitudinally provided with one to two rows of plurality of marble holes; the hole is internally placed with a spring and one marble which is provided with one to more circular grooves; auxiliary marble grooves are arranged vertically to the marble holes and are internally provided with auxiliary marbles which are provided with a plurality of round holes corresponding to the marble holes; the tail of the front locking core is provided with a front clutch pin groove; a rear clutch pin groove is arranged at the rear locking core and is internally provided with a spring and a clutch pin; the rear end of the clutch pin is provided with an inclined surface; and a locking groove is arranged in the shell at the position corresponding to the clutch pin groove. When a lock is locked, the front locking core is in idling state, when foreign matters or an unlocking tool is inserted, the front locking core can be rotated randomly, but the lock can not be unlocked, so the theft prevention of the lock is very high.

Description

A kind of marble idle rotation lock head

Technical field:

The utility model relates to a kind of lock, and in particular, it relates to a kind of ball lock head.

Background technology:

Existing ball lock head majority by housing, be enclosed within that rotating lock core and pellet shot from a slingshot etc. thereof constitute in the housing, housing corresponding with lock core have several pellet shot from a slingshot holes, a spring is put in each pellet shot from a slingshot hole, a housing pellet shot from a slingshot, a lock core marble.During locking, housing pellet shot from a slingshot insertion lock core in various degree is stuck in prevention lock core rotation between housing and the lock core.The lock of this structure can be twisted off when lock core is inserted the pellet shot from a slingshot that stops lock core to rotate when keyhole is done powerful reversing by special instrument, makes this lock lose anti-theft feature.

Summary of the invention:

The purpose of this utility model provides a kind of marble idle rotation lock head that can overcome existing defective in the prior art, its lock core is in idling conditions when locking, insert unlocking tool or other objects, can rotational lock core but this lock be not unlocked, have improper functions of unblanking such as the defence brute force is unblanked, technology unlocking, theftproof is very good.

The utility model is achieved by the following technical solution: it is by housing, preceding lock core, rear lock core, formations such as pellet shot from a slingshot, lock core is preceding before described, rear lock core after, be sleeved in the housing, rear lock core is the main body of unblanking, vertically have one to two several pellet shot from a slingshot holes of row at preceding lock core, put into a spring in each pellet shot from a slingshot hole, a pellet shot from a slingshot, pellet shot from a slingshot has one or more annular groove, and the head of pellet shot from a slingshot stretches in the keyhole, vertically has secondary bullet groove perpendicular to the pellet shot from a slingshot hole, the afterbody of lock core before secondary bullet groove extends to, built-in secondary pellet shot from a slingshot, secondary pellet shot from a slingshot has several circular holes, and circular hole is corresponding with the pellet shot from a slingshot hole, clutch cotter way before the afterbody of preceding lock core has, have back clutch cotter way, built-in spring, on-of pin at rear lock core corresponding to preceding clutch cotter way, the rear end of on-of pin is provided with one or more inclined-plane, has lock slots corresponding to back clutch cotter way place in housing.

The utility model marble idle rotation lock head is in idling conditions when locking, when inserting, foreign matter or unlocking tool can rotate preceding lock core arbitrarily, but can not unblank, so this lock can effectively be defendd improper means of unblanking such as brute force is unblanked, technology unlocking, theftproof is very high.

The specific embodiment:

Fig. 1-the 4th, first embodiment of the present utility model is made of housing 1, preceding lock core 2, rear lock core 3, pellet shot from a slingshot 5 etc.Lock core 2 is preceding before described, rear lock core 3 after, be sleeved in the housing 1, rear lock core 3 is the main body of unblanking, vertically have several pellet shot from a slingshot holes 4 of row at preceding

lock core

2,6, one pellets shot from a slingshot 5 of a spring are put in each pellet shot from a slingshot hole 4, and the head of pellet shot from a slingshot 5 stretches in the keyhole 8, pellet shot from a slingshot 5 has annular groove 19, vertically have secondary bullet groove 9 perpendicular to pellet shot from a slingshot hole 4, the afterbody of lock core 2 before secondary bullet groove 9 extends to, built-in secondary pellet shot from a slingshot 10, the inner of secondary pellet shot from a slingshot 10 is provided with several circular holes 11, circular hole 11 is corresponding with pellet shot from a slingshot hole 4, and the afterbody of preceding lock core 2 has preceding clutch cotter way 13, has back clutch cotter way 14 at rear lock core 3 corresponding to preceding clutch cotter way 13, a built-in spring 18, an on-of pin 15, the rear end of on-of pin 15 have an inclined-plane 12, have lock slots 17 corresponding to back clutch cotter way 14 places in housing 1.As shown in Figure 3, Figure 4, when unblanking, key 16 inserts, the annular groove 19 of each pellet shot from a slingshot 5 is all to chief and vice pellet shot from a slingshot 10 under the effect of key 16, on-of pin 15 and secondary pellet shot from a slingshot 10 move together under the effect of spring 18, the contact edge of the circular hole 11 of secondary pellet shot from a slingshot 10 enters in the annular groove 19 of pellet shot from a slingshot 5, on-of pin 15 is under the effect on inclined-plane 12, make oblique movement, in the preceding clutch cotter way 13 of lock core 2, lock core 2 and rear lock core 3 were connected as a single entity before making, simultaneously before its front end inserted, the keyed end of on-of pin 15 withdraws from from the lock slots 17 of housing 1, at this moment twists key 16 and just can unblank.During locking, extract key 16, pellet shot from a slingshot 5 outwards moves under the effect of spring 6, the annular groove 19 of pellet shot from a slingshot 5 departs from secondary pellet shot from a slingshot 10, the top is compeled secondary pellet shot from a slingshot 10 and is moved backward, secondary pellet shot from a slingshot 10 promotes on-of pin 15, and on-of pin 15 is made oblique movement under the effect on inclined-plane 12, the preceding clutch cotter way 13 of lock core 2 before the front end of on-of pin 15 is withdrawed from, preceding lock core 2 separates fully with rear lock core 3, and preceding lock core 2 is in idling conditions, and the keyed end of on-of pin 15 inserts the lock slots 17 of
