Abstract

The utility model discloses a three-core idle mechanical lock head which comprises a lock shell; two radial grooves are arranged on the inner wall of the lock shell; the lock shell is subsequently provided with three lock cores from outside to inside, i.e. a No. 1 core, a No. 2 core and a No. 3 core; two No. 1 core edge holes which are matched with the grooves are arranged outside the No. 1 core, the No. 1 core and the shell are jointed by a retaining ring, the retaining ring is arranged in a retaining ring slot, and the front end of a No. 1 core chamber is provided with a round of circumferential snap ring grooves; and the three-core idle mechanical lock head has the advantages that because billiards are hidden in a No. 3 lock core slide way, and only a right key can adjust gaps on the billiards on the same straight line and on the same height.

Description

A kind of three courages idle running mechanical lock head

Technical field

Relate to a kind of tapered end in utility model, a kind of specifically idle running mechanical lock head.

Background technology

Mechanical lock head of the prior art generally comprises shell body, lock gall, spring, pellet shot from a slingshot, jump ring, key.The shortcoming of this class tapered end is: spring has two pellets shot from a slingshot in the shell hole in lock housing, also deserve to be called down pellet shot from a slingshot; During lock-out state, a pellet shot from a slingshot is in lock gall, and another pellet shot from a slingshot is between lock gall and lock housing, and the pinning center lock gall can not rotate; During unlocking condition, key is adjusted pellet shot from a slingshot, and a pellet shot from a slingshot is in lock gall, and a pellet shot from a slingshot is in lock housing, and this structure exists very easily by technical unlocking; The tartar amount is few, mutual opening rate height, and not anti-drilling and strong button.Some double ball lock heads in recent years, though technical unlocking has had an irregular difficulty, anti-strong button and anti-drilling aspect also difficulty resist.

Summary of the invention

At existing mechanical tapered end shortcoming, the utility model provides a kind of three novel courages idle running mechanical lock head.

To achieve these goals, the measure taked of the utility model:

A kind of three courages idle running mechanical lock head, include the lock shell, the inwall of lock shell has two radial grooves, be provided with three lock galls from outside to inside successively in the lock shell, be respectively courage No. one, No. two courages, No. three courages, courage be provided with outward two with the cave, a courage limit of groove coupling, between courage and the shell by the jump ring clamping, and jump ring is positioned at the jump ring groove, a courage thorax front end is provided with ending of circumference of ring and groove, and be provided with the bullet pin-and-hole of wearing, No. three courage radially is respectively equipped with the hole, limit in both sides, equipped pellet shot from a slingshot in the pellet shot from a slingshot chute of No. three courages, the pellet shot from a slingshot spring, magnetite is provided with magnetite in the hole, the front end of No. three courages is provided with a pellet shot from a slingshot pin cave of wearing thoroughly, the pellet shot from a slingshot pin is provided with the bullet pin in the cave, and the bullet at bullet pin two ends passes No. two bullet pin-and-holes on the courage and groove with ending of a courage front end and match, and side column is positioned at groove, cave, a courage limit, between No. two caves, courage limit and hole, limit, the lower edge of No. three courages the or middle key that can adjust pellet shot from a slingshot arranged, key inserts in the key;

The concave arc and the axle that are provided with in the described pellet shot from a slingshot suit, and the evagination circular arc suits mutually with No. three courage inwall arcs, and to be provided with arc scarce for the corresponding pellet shot from a slingshot correspondence of encoding on the pellet shot from a slingshot evagination circular arc;

Described side column material is an iron.

The beneficial effects of the utility model: because pellet shot from a slingshot is to hide in No. three lock gall chutes, only match key could adjust breach on the pellet shot from a slingshot and be a straight line and highly.Lock could normal be opened, and when improper object inserted keyhole and rotates, the side column that plays locking action was idling conditions with No. two courages, No. three courages disengagings, the binding energy of the two defense technique unlatching and turn on the tool that undoes the lock by force to greatest extent.

The specific embodiment

A kind of three courages idle running mechanical lock head, as shown in Figure 1 and Figure 2, comprise lock shell 1, groove 2, courage 3, cave, courage limit 4, jump ring groove 5, a jump ring 6, end groove 7, No. two courages 8, No. two caves, courage limit 9, playing pin-and-hole 10, No. three courages 11, holes, limit 12, play pin runner 13, magnetite hole 14, magnetite 15, pellet shot from a slingshot 16, pellet shot from a slingshot spring 17, pellet shot from a slingshot pin cave 18, bullet pin 19, side column 20, key 21, key 22 and form, lock shell 1 interior bore has been done 2, numbers courages 3 of a groove respectively to both sides and has been fixed and be arranged in the lock shell 1 by jump ring groove 5 and jump ring 6; Courage 3 radially both sides groove 2 of having done cave, 4, numbers courage limits, cave, a courage limit 4 and lock shell 1 respectively is complementary, and courage 3 thorax front portions are provided with ending of ring week and groove 7; No. two courages 8 radially both sides are respectively arranged with 9, No. two courage 8 front ends in cave, No. two limits and do and be provided with the bullet pin-and-hole of wearing 10; No. three courages 11 radially both sides divide and are provided with 12, No. three courages 11 in hole, limit in addition and are provided with and play pin runner 13, magnetite hole 14, play in the pin runner 13 and are provided with pellet shot from a slingshot 16, pellet shot from a slingshot spring 17, are provided with magnetite 15 in the magnetite hole 14; A pellet shot from a slingshot pin cave 18 of wearing is thoroughly done in the front portion of No. three courages 11, is provided with bullet pin 19 in the pellet shot from a slingshot pin cave 18, the bullet at bullet pin 19 two ends pass No. two on the courage 8 bullet pin-and-hole 10 and groove 7 with ending of courage 3 front portions and match; No. two courages 8 is equipped mutually with a courage 3 with No. three courages 11 and assembly thereof; Side column 20 is hidden in groove 2, cave, courage limit 4, No. two caves 9, courage limit and hole, limit 12; The lower edge of No. three courages 11 is provided with the key 21 that can adjust pellet shot from a slingshot 16; Key 22 inserts or extracts adjusting pellet shot from a slingshot 16 by key 21 and realizes opening and locking.When lacking of pellet shot from a slingshot 16 in No. three courages 11 do not adjusted to same parallel that the footpath makes progress, No. three courages 11 and No. two courages 8 were synchronous idles.Can not open locking bit, have only correct key 22 being inserted in No. three courage 11 key 21, with the unordered breach of all pellets shot from a slingshot 16 wrong rules transfer cause radially same when parallel, magnetic attraction in No. three courages 11 is drawn to the hole, limits 12 on the bullet 11 No. three with the irony side column, in the space of cave, No. two courage limits 9, cave, courage limit 4 combinations, No. two courages 8, could courage of transmission 3 work unlatching locking bits when No. three courages 11 rotate.The gravitation to central motion of side column 20 is magnetic attraction; Outwards the power of motion is spring energized in pellet shot from a slingshot 16, and pellet shot from a slingshot 16 is done to move the extruding force that pellet shot from a slingshot 16 arc breach are executed side column 20 around axle.During lock-out state, unnormal unlocking, No. two courages 8 and No. three courages 11 are idling conditions, during normal opening, courage 3, No. two courages 8, No. three courages 11 rotate in the lump.As shown in the figure, key 22 can be opened from the centre.

This structural principle can extensively expand and fair is applied to make all size, all kinds, various uses lockset tapered end, and can mate with the on-mechanical lockset.
