Abstract

The utility model discloses a double-row irregular spring lock, comprising irregular springs on a lock core, a lock body and a key. The double-row irregular spring lock is provided with spring holes which are symmetrical and are arranged along the axial position of one end of the lock core, and the inner part of the spring holes is arranged in turn with conical-head springs with guide grooves. Jacks distributed at different positions in each spring guide groove are corresponding to the pawls of the double-row irregular springs arranged in grooves which are provided with the jacks at both sides of the lock core, and are matched with the grooves in a lock casing. The double-row irregular spring lock is provided with a double-row type key, and also comprises anti-drill steel pins which are arranged on the same line of each spring corresponding to the head of the lock core. The utility model has the advantages of large key size, difficult key imitation and high anti-theft and safe performance.

Description

Double row profile spring lock

A kind of cylinder lock that has tumbler of the new genus of this practicality is that a kind of axially-aligned becomes double special-shaped marble lock specifically.Mainly be that prior art has been done improvement.

Disclosed Double-line bear lock in the CN2145231Y technology of known bulletin, it mainly is to have utilized the upper and lower installation decorative pearl on top of an official cap of lock core and lock body same center line radially and envelope pearl, and has in-line and up and down be provided with the key of row's key bit in the side; The existing market lock is sold the prismatic and the four prismatics lock of use for another example.The design feature of this lock is that the pellet shot from a slingshot that is provided with in lock core is 120 degree and 90 degree respectively, and key is prismatic and cross shape.The lock of above-mentioned several form of structure all is to utilize the lock pearl in the lock core directly to contact formation with lock core shell with the envelope pearl under the effect of spring, though increase the tooth and the lock core marble of key, improved size of key, characteristics with the low and confidentiality of mutual opening rate, but still utilize the lock pearl kayser that is distributed in the corresponding hole of bead of lock body on the overall structure with lock core, therefore, the anti-foreign matter of all kind locks is opened ability.

The new purpose of this practicality provides a kind of improved double special-shaped marble lock, by the pick-proof of lock head and the special-shaped marble lock construction of face contact, has realized the whole reliable and secure performance of lock.

For achieving the above object, the utility model is realized by following measure, have in the pellet shot from a slingshot hole of the double symmetry that has along the axial position of lock core one end, the conehead pellet shot from a slingshot of tape guide groove is housed successively, the claw that lock hole that diverse location distributes in each pellet shot from a slingshot gathering sill and open hole have with the lock core both sides on the double special-shaped marble of installing in the groove of jack is corresponding and identical with the groove in the lock housing, and has double type key; And be included on the same line of head corresponding to each pellet shot from a slingshot of lock core anti-drilling steel pin is set.

Characteristics of the present utility model are:

1, adopts dual interlock mechanism, utilize lock hole and open hole on cylinder bullet, define the rotation of lock core both sides special-shaped marble and lock housing effectively, thereby improved the security reliability of lock.

2, used double asymmetric key toothing, it is big to have close copper amount, and key is difficult to copy, and has improved security performance.

3, the critical position of this lock is equipped with anti-drilling steel pin respectively, strengthens the protective of lock core marble, makes it be difficult to destroy main lock, has higher anti-theft security performance.

Description of drawings:

Fig. 1 is the topology view of double special-shaped marble lock.

Embodiment further describes in conjunction with the accompanying drawings:

And Fig. 1, lock core 14 adopts in the double symmetrical pellet shot from a slingshot hole 12 that has on the axial end position, set gradually conehead cylindrical billiard 10, be enclosed in the pellet shot from a slingshot hole 12 by spring 7 and pressing plate 8, it is big to make it to have size of key, the security performance height, and all have in the gathering sill on each cylinder 10, diverse location is respectively equipped with lock hole and open hole 11, and the degree of depth in two holes of each lock hole and open hole 11 is different, and promptly the degree of depth of lock hole is more shallow.Respectively have on the lock core 14 of 12 both sides, vertical corresponding cylindrical billiard hole and have in the long recess groove and the 12 corresponding claw holes 13 that communicate, pellet shot from a slingshot hole.The special-shaped marble 3 that will have claw 4 is installed in the long recess, spring 2 is housed between special-shaped marble 3 and the groove, one end and being fixedly installed in the hole 9 on the special-shaped marble 3, make it of the effect of different pellet shot from a slingshot by spring 2, make claw hole 13 stretching motions of claw 4 in groove, special-shaped marble 3 symmetries of lock core 14 both sides are packed in the groove 6 on lock housing 5 internal diameters.For prevent to bore, the unlatching of foreign matter such as sledge, on the same line of corresponding each pellet shot from a slingshot of the head of lock core 14 anti-drilling steel pin 1 is housed, and has " U " type row key 15.

After double key inserts, make on the cylindrical billiard 10 and move, the claw 4 of the corresponding special-shaped marble 3 of the open hole 11--on it is during key turns, special-shaped marble 3 is squeezed claw 4 is inserted in the open hole 11 on the pellets shot from a slingshot 10, and the grooves 6 that special-shaped son 3 breaks away from the core shells 5 are opened lock; When extracting key, the special-shaped marble 3 disengaging open holes 11 of cylindrical billiard 10 are corresponding with lock hole, and special-shaped marble 3 loses motion and pins.
