Abstract

The utility model discloses an anti-theft cylinder with an improved structure. A stagewise cylinder structure is adopted; a section of key cylinder (2) is arranged in each stage, arranged inside a jacket (7), and respectively controls a chuck (6) for locking; a key is respectively provided with a key unlocking position which is matched with a key cylinder unlocking position (3) of each stage of key cylinder and can be stagewisely inserted into a key hole (4) of each section of key cylinder and then turned around stagewisely so as to drive a corresponding chuck to lock or unlock. The anti-theft cylinder is simple in structure and easy to process and manufacture; an anti-theft lock comprising the anti-theft cylinder has better anti-theft performance.

Description

A kind of anti-theft lock end that improves structure

Technical field

The utility model relates to a kind of theftproof lock, is a kind of anti-theft lock end that improves structure specifically.

Background technology

Known theftproof lock has miscellaneous on the market, but because its tapered end is generally to adopt the form that one-level twists once, a card is a bayonet lock to make, its anti-theft effect is also just barely satisfactory, easily by strong scissors, is cut off, or is easy to be opened by robber.Thief can utilize special tool to insert lock core lock body is opened, and theftproof performance is poor.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-theft lock end that improves structure, and the theftproof performance of the theftproof lock made from it is more good.

A kind of anti-theft lock end that improves structure that the utility model provides, adopt the lock core structure of stagewise, every grade is respectively arranged with a joint lock core, be arranged in overcoat, every joint lock core is controlled respectively a dop that is used for locking, thereby key is respectively arranged with the keyhole that coordinates, can insert step by step every joint lock core with the lock core unlock position of every joint lock core, reverses and drives corresponding dop to realize the key unlocking position of locking or unblanking step by step again.

In above-mentioned, the tumbler that every joint lock core forms keyhole is respectively arranged with annular tooth, on corresponding dop, is provided with the straight-tooth engaging with annular tooth.The keyhole that key inserts last joint lock core reverses the keyhole that can advance next joint lock core after 45 degree again.

The utility model adopts the lock core structure of stagewise, and every joint lock core is controlled respectively a dop that is used for locking, and the theftproof performance of the theftproof lock made from it is more good.It is simple in structure, processing and fabricating is easy.

Fig. 4 is the left view of Fig. 3.

Fig. 5 is the structural representation of key of the present utility model.

Fig. 6 is the structural representation that the utility model is applied to U-shape lock.

The specific embodiment

The utility model is provided with two joint lock cores as example take two-stage lock core, but can not limit the utility model with this.

Referring to figs. 1 through Fig. 5, a kind of anti-theft lock end that improves structure that the utility model provides, this anti-theft lock end 1 adopts the lock core structure of stagewise, for two-stage, every grade is respectively arranged with a joint lock core 2, be arranged in overcoat 7, every joint lock core 2 is controlled respectively a dop that is used for locking 6, and key 10 is respectively arranged with the lock core unlock position 3 of every joint lock core 2 joins

thereby the keyhole 4 that closes, can insert step by step every joint lock core 2 reverses and drives corresponding dop 6 to realize the key unlocking position 11 of locking or unblanking step by step again, after reversing 45 degree again, the keyhole that key 10 inserts last joint lock core can advance next to save the keyhole 4 of lock core.

The tumbler 5 that every joint lock core 2 forms keyhole 4 is respectively arranged with annular tooth 9, on corresponding dop 5, is provided with the straight-tooth 8 engaging with annular tooth.

Fig. 6 is the structural representation that the utility model is applied to U-shape lock, U-shaped 14 1 free ends of this U-shape lock are connected with anti-theft lock end 1 by locking bolt socket piece 13, the other end has two locking bolt holes, and two front ends can advance 13 li of lockings of locking bolt socket piece by locking bolt hole with the locking bolt 12 of bayonet socket.

During use, see Fig. 6, first key 10 is inserted to last joint lock core 2 along keyhole, corresponding key unlocking position 11 on key 10 is seasonable with 11 pairs of the key unlocking positions of last joint lock core 2, twisting key makes last joint lock core 2 rotate 45 degree by clockwise direction, last joint lock core 2 and then rotates 45 degree too, annular tooth 9 on last joint lock core 2 also can drive corresponding dop 6 to do motion from top to bottom by straight-tooth 8 simultaneously, corresponding dop 6 just departs from the bayonet socket of corresponding locking bolt 12 like this, this locking bolt 12 just can freely pull out propelling, namely this locking bolt 12 has been opened.When last joint lock core 2 rotates 45 while spending, just align with the keyhole 4 of next joint lock core, now, key just can continue to insert the keyhole 4 of next joint lock core, then by above-mentioned steps, this joint lock core is rotated, now, two joint lock cores 2 rotate simultaneously, and corresponding dop 5 just departs from the bayonet socket of this locking bolt 12, and this locking bolt 12 just can pull out and advance freely, article two, locking bolt 12 has been opened, and is equivalent to unblank.Reverse operating thus, just can pin two locking bolts 12.If need, can increase joint number.

This anti-theft lock end 1 of many uses, can be used for the product of other different purposes.

Claims

1. one kind is improved the anti-theft lock end of structure, it is characterized in that, adopt the lock core structure of stagewise, every grade is respectively arranged with a joint lock core (2), be arranged in overcoat (7), every joint lock core (2) is controlled respectively a dop that is used for locking (6), key (10) be respectively arranged with the lock core unlock position (3) of every joint lock core (2) coordinate, can insert step by step every joint lock core (2) keyhole (4) thus more step by step reverse drive corresponding dop (6) to realize the key unlocking position (11) of locking or unblanking.
