Abstract

The utility model discloses a lock cylinder including a lock casing and a lock pin arranged in the lock casing, a lock hole is arranged in the lock pin, a blade spring equipped with a V-shaped groove and a flexible locking edge column pressing inward fitted with the V-shaped groove on the blade spring are arranged in the lock pin, a dial block is arranged at the tail of the lock pin, and the inner surface of the lock casing is provided with two edge column grooves fitted with the locking edge column. Because the two edge column grooves are arranged on the inner surface of the lock casing in the lock cylinder, double locking can be realized at two positions through the cooperation of the flexible locking edge column and the edge column grooves while the lock pin is rotated, and the lockset and the locking bolt controlled by the dial block at the tail of the lock pin can be locked at two positions. The lock cylinder can improve the reliability and the safety by applying on the lockset, particularly, on a T-shaped steering wheel lock.

Description

A kind of tapered end

Technical field

The utility model belongs to lockset, particularly a kind of tapered end.

Background technology

Existing T type handle lock such as Fig. 1, shown in Figure 2, it during vehicle steering, is to utilize snap close 1 and the circle ring 7 of lock body 2 with bearing circle to grasp at lock, the locking bolt 5 of ratchet shape cooperates locking on the locking bar 3 that utilizes band ratchet 4 on the snap close 1 and the lock body 2.The tapered end that the lockout mechanism of this handle lock adopts is common side column tapered end; Comprise lock shell and the interior lock core of lock shell; Lock core is provided with lockhole, is provided with the blade marble of band V-shaped groove in the lock core and the elastic locking side column of the inside pressure that cooperates with V-shaped groove on the blade marble, locks shell and is provided with and the cooresponding marble spring of blade marble; The lock core afterbody is provided with the shifting block 8 that cooperates with locking bolt 5, and lock shell inside face is provided with one and the cooresponding side column groove of locking side column.When unblanking; Insert key from lockhole; Locking side column is from the side column groove withdrawal lock core of lock shell, can rotational lock core, and utilize the shifting block 8 of lock core tail end to cooperate with groove 501 on the locking bolt 5; Drive locking bolt 5 and move downward the ratchet 4 that breaks away from the locking bar 3, locking bar 3 drives snap close 1 under the effect of pull back spring 6 separates with lock body 2.During locking, key drives to be extracted after lock core resets, and locking side column stretches into the side column groove of lock shell, can not rotational lock core, locking bolt 5 the effect of pull back spring 9 under with locking bar 3 on ratchet 4 cooperate, make locking bar 3 to move to locking direction.Because this tapered end has only a latched position; The shifting block 8 of lock core afterbody is positioned at the bottom of locking bolt 5 upper grooves 501; And the height of groove 501 is greater than the size of shifting block 8; Unfettered when locking bolt 5 moves downward, produce vibration if beat lock body, the moment that locking bolt 5 is moved downward breaks away from opened lock with cooperating of locking bar 3.Therefore, there is potential safety hazard during especially for automobile steering lock in existing tapered end when using.

The utility model content

The purpose of the utility model just provides a kind of reliability and the higher tapered end of safety.

Realize that the technical scheme that the utility model purpose adopts is: tapered end comprises lock shell and the lock core that is located in the lock shell; Lock core is provided with lockhole; The elastic locking side column of the inside pressure that is provided with the blade marble of band V-shaped groove in the lock core and cooperates with V-shaped groove on the blade marble; The lock core afterbody is provided with shifting block, and lock shell inside face is provided with two side column grooves that cooperate with locking side column.

Said two side column grooves become 90 degree to be provided with.

The utility model is provided with two side column grooves owing to lock the shell inside face in the tapered end; Can realize twice locking through elastic locking side column and cooperating of side column groove in position, two places during rotational lock core, the lockset locking bolt of being controlled by lock core afterbody shifting block also can lock in position, two places.The utility model tapered end can improve reliability and safety when being used for lockset especially for T type handle lock.

The specific embodiment

Like Fig. 3, shown in Figure 4; The utility model tapered end comprises lock shell 10 and the lock core 11 that is located in the lock shell 10; Lock core 11 is provided with lockhole 13; Be provided with the blade marble 12 of band V-shaped groove 1201 and the locking side column 14 that cooperates with V-shaped groove 1201 on the blade marble 12 in the lock core 11, the two ends of locking side column 14 are provided with spring 16 capped 17 and are fixed on and constitute the inwardly elastic locking side column of pressure on the lock core 11, and lock core 11 afterbodys are provided with shifting block 8; Lock shell 10 inside faces are provided with two

side column grooves

15,18 that cooperate with locking side column 14 by 90 degree settings, and lock shell 10 is provided with and blade marble 12 cooresponding marble springs 19.

The principle of work of the utility model is that example describes (referring to Fig. 1, Fig. 2) with T type handle lock:

Locking: see Fig. 4; Article one side column groove 15 that locking side column 14 in the lock core 11 stretches on the lock shell 10 is locking for the first time; The shifting block 8 of lock core 11 afterbodys withstands on 501 tops of the groove on the locking bolt 5 in the handle lock lock body 2; With locking bolt 5 diebacks, can prevent to produce vibration through beaing lock body 2, the moment that locking bolt 5 is moved downward break away from snap close 1 in cooperating of locking bar 3 lock is opened.

Unblank: see Fig. 5, insert lockholes 13 with key 20, blade marble 12 is arranged again, V-shaped groove 1201 alignment on it, and V-shaped groove 1201 is gone in indentations in the locking side column 14, withdraws from from the side column groove of locking on the shell 10 15 simultaneously, at this moment can rotational lock core 11; See Fig. 6; Clockwise rotates 180 degree with lock core 11; The shifting block 8 of lock core 11 afterbodys drive locking bolts 5 move downward with snap close 1 in ratchet 4 on the locking bar 3 break away from, locking bar 3 breaks away from lock body 2 with snap close 1 and realizes unblanking under the effect of pull back spring 6, can lockset be unloaded from bearing circle; Anticlockwise then with lock core 11 rotations 90 degree, locking bolt 5 is extracted key with lock core 11 returns; As shown in Figure 7; At this moment locking side column 14 stretches into second side column groove 18 locking for the second time on the lock shell 10, and the shifting block 8 of lock core 11 afterbodys drops on groove 501 bottoms on the locking bolt 5, and at this moment locking bolt 5 is not by dieback; Ratchet 4 mated condition on the locking bar 3 in maintenance and the snap close 1 under the effect of its retracing spring 9; But it moves downward not restrained, so that when locking, snap close 1 relative lock body 2 can only be to the motion of locking direction.

Lock: the snap close 1 and the lock body 2 of handle lock are clamped on the annulus 7 of bearing circle, push hard snap close 1 lockset firmly is fixed on the bearing circle, insert key, extract the key completion and lock lock core 11 anticlockwise rotation 90 degree to states shown in Figure 4.
