Abstract

The invention discloses a lock cylinder which is of a front and back separation and reunion structure and can idle even if an internal-pressure side pin is inclined. The lock cylinder comprises a lock 5, a lock cylinder body, the special-shaped internal-pressure side pin 3 and the like, wherein the lock cylinder body comprises a front lock cylinder and a rear lock cylinder, the special-shaped internal-pressure side pin capable of being matched with a sheet groove 72 or a pin groove is arranged inside the front lock cylinder, a high boss is arranged at one end of the side pin, and a low concave platform is arranged at the other end of the side pin. The internal-pressure side pin cannot realize a transmission effect but can only realize a gripping effect for separating and reuniting the front lock cylinder and the rear lock cylinder; the internal-pressure side pin is clamped by the rear lock cylinder or the lock no matter which side the special-shaped internal-pressure side pin is inclined to; and only after a matched key is inserted into the lock cylinder body and the internal-pressure side pin is parallelly sunken to a set position, the front lock cylinder can be pushed towards the rear lock cylinder to realize a meshed transmission effect.

Description

A kind of lock core clutch structure that can dally

Technical field

The present invention and a kind of mechanical lock are a kind of lock core clutch structures of idle running.

Background technology

At present disclosed idle-run lock pin great majority adopt front and back clutch or the inner-outer sleeve clutch structures of inner edge pin on the market, thus the flanging pin idle rotation on-off inefficacy of will tilting in after the identical key of part tartar inserts lock core.

Summary of the invention

Even technical problem to be solved by this invention provides front and back that a kind of interior flanging pin tilts also can realize dallying from structured lock core.The present invention is achieved in that flanging pin 3 in a kind of different form is set, one of the side column pin arranges high boss 31, the other end arranges low boss 32, interior flanging pin is not done gearing, only do the snib effect of front lock and rear lock clutch, no matter flanging pin 3 toward which limit tilts in the different form, interior flanging pin is all blocked by rear lock core 22 or tapered end 51, only have after matched key inserts lock core, front lock core could be realized the interlock transmission to the rear lock core propelling after interior flanging pin bodily sinkage arrived the position of setting.

Flanging pin 3 is applicable to hinge lock core and the Spring cylinder lock core that all adopt interior flanging pin in the above-mentioned different form.

The specific embodiment

A kind of lock core clutch structure of idle running, structure shown in Figure 1 comprises tapered end 5, lock core, the interior flanging pin 3 of abnormity etc., wherein lock core includes front lock 1 and rear lock core 2, in front lock core 1, be provided with flanging pin 3 in the abnormity that can match with hinge groove 72 or pellet groove, one of side column pin 3 arranges high boss 31, the other end arranges low boss 32, interior flanging pin 3 is not done gearing, the snib effect of lock 1 and rear lock core 2 clutches before only doing, no matter flanging pin 3 toward which limit tilts in the different form, interior flanging pin 3 is all blocked by rear lock core 22 or tapered end 51, only have behind lock core 1 before the matched key insertion, front lock core 1 could advance realization interlock transmissions to rear lock core 2 after interior flanging pin 3 bodily sinkages arrived the position of setting.

Figure 2 shows that this structure unlocking condition generalized section, only have behind lock core 1 before matched key 8 insertions, interior flanging pin 3 is under the effect of return spring, 36 of interior flanging pins and front lock core periphery 15 maintain an equal level, interior flanging pin 35 faces fall into rear lock core inwall 23, interior flanging pin 38 emaciated faces are from 22 of rear lock cores, and at this moment interior flanging pin 3 has not been blocked by rear lock core 22 or tapered end 51, and front lock core just can advance to rear lock core and realize the interlock transmission.

Figure 3 shows that this structure blocking generalized section, Figure 5 shows that the part component drawing of this structure.When matched key 8 is extracted in the process of front lock core 1, front lock core 11 leaves rear lock core breach 21 and outwards withdraws from, under the promotion of hinge groove 72 and interior flanging pin 39, the interior flanging pin 3 parallel positions that rise to setting, at this moment interior flanging pin 38 is blocked in 22 slips of rear lock core; Flanging pin 37 also is blocked in 51 slips of tapered end simultaneously.Lock core 1 separates with rear lock core 2 before under the above-mentioned state, and front lock core can be realized idle running and can't the transmission rear lock core.Lock core 1 coincide the part hinge before non-matching key inserts as shown in Figure 4, heeling condition appears at the lower inside flanging pin 3 of the effect of return spring, although flanging pin 38 has broken away from rear lock core 22 at this moment, and interior flanging pin 37 is also blocked by tapered end 51 faces, can only be in 51 slips of tapered end, front lock core also can't advance to rear lock core and realize the interlock transmission.

Figure 6 shows that another kind of front and back lock core occlusion structure stereogram, this structure can be used the above-mentioned operating principle of flanging pin 3 in the abnormity equally.

Claims

1. a hinge lock core or the Spring cylinder lock core clutch structure that can dally, comprise tapered end 5, lock core, the interior flanging pin 3 of abnormity etc., wherein lock core includes front lock 1 and rear lock core 2, in front lock core, be provided with flanging pin 3 in the abnormity that can match with hinge groove 72 or pellet groove, offer groove 33 in the middle of it is characterized in that, push back a spring 9 in arranging, one of the side column pin arranges high boss 31 (contacting with tapered end step 51) under blocking, the other end arranges low boss 32 (contacting with rear lock core 22) under blocking, the discrepancy in elevation of high boss 31 and low boss 32 equates with hinge groove or pellet groove or matches; The thickness of low boss 32 also is that the discrepancy in elevation of high boss 31 and low boss 32 equates or matches.Interior flanging pin is not done gearing, only do the snib effect of front lock and rear lock clutch, no matter flanging pin 3 toward which limit tilts in the different form, interior flanging pin is all blocked by rear lock core 22 or tapered end 51, only have after matched key inserts lock core, front lock core could be realized the interlock transmission to the rear lock core propelling after interior flanging pin 3 bodily sinkages arrived the position of setting.Interior flanging pin 3 bodily sinkages are that 36 of interior flanging pins and front lock core periphery 15 maintain an equal level to the position feature of setting, and interior flanging pin 35 faces fall into rear lock core inwall 23, and interior flanging pin 38 emaciated faces are from 22 of rear lock cores.

2. the interior flanging pin 3 of described front lock core 1 and rear lock core 2 clutch structures is equally applicable to the clutch structure of front lock core 111 and rear lock core 222 according to claim 1.
