Abstract

The utility model relates to a gear-typed multi-row spring lock, comprising a lock tube, a lock core tube, a core rod, etc. The inner tube of the lock core tube is provided with four to six longitudinal flutes along the symmetrical position of the radial centerline, and the inner side of the flutes is provided with a long spring, a short spring and a semi-through spring. The used key is provided with four to six longitudinal lug bosses on a key tube along the symmetrical position of the radial centerline, the four to six longitudinal lug bosses are corresponding to the flutes on the lock core tube, and key tooth forms are arranged on the lug bosses and are respectively corresponding to the long spring, the short spring and the semi-through spring. The utility model enlarges the gap between the inner wall of the lock core tube and the core rod, enhances the long-short change quantity of the springs, enhances the size of key, has the advantages of anti-bore and anti-prizing performance, good key intensity and difficult spring abrasion, and is suitable for the use of various door locks, padlocks and safe locks.

Description

Gear type multi-row billiard lock

The utility model relates to a kind of gear-like and arranges cylinder lock more, contains tapered end pipe, lock core pipe, core bar etc.

At present, salable on the market at home have a homemade cylinder lock with dull and stereotyped three prismatic keys that produces with the homemade cylinder lock with the tee T key of cylinder lock, the method for cruciate flower shape key, Israel; More than the advantage of various locks be that key tooth flower is many, but that its weak point is the keyhole hole of lock is big, not anti-drilling, easily destroyed by drill bit and open tapered end, and size of key is still lower.For solving anti-drilling problem, improve size of key; In Chinese patent " 90226236.X ", disclose a kind of " arranging cylinder lock " more, its design feature is that the endoporus of lock core pipe is polygon cylindricality, core bar is arranged in the lock core pipe, the shape of core bar is corresponding with the shape of lock core pipe, in lock core pipe, be placed with many row's pellets shot from a slingshot, row's number of many row's pellets shot from a slingshot is identical with the limit number of lock core pipe endoporus, and the gap of lock core pipe and core bar is less, and being shaped as of employed key is double-deck polygon tubular; It is antitheft to arrange cylinder locks more, anti-drilling, its weak point is because the machining accuracy of core bar and lock core pipe is not good, easily cause the gap between lock core pipe and the core bar inhomogeneous, make when unblanking feel not good, in addition, also require the wall thickness of key pipe can not be too thick, thereby make in the lock core the long and short variation of pellet shot from a slingshot less, reduced size of key; And, because the easy abrasion pellet shot from a slingshot of thread form of employed key.For solving the pellet shot from a slingshot wear problem, simplify pellet shot from a slingshot and produce worker's treatment, a kind of " steel ball lock " disclosed in Chinese patent 92222819.1, be characterized on many row's cylinder locks, slightly making improvements, promptly replace pellet shot from a slingshot with steel ball, its shortcoming is identical with above-mentioned many rows cylinder lock.

The purpose of this utility model is that the pellet shot from a slingshot varied number is big in a kind of lock core that provides for fear of above-mentioned the deficiencies in the prior art part, size of key is high, pellet shot from a slingshot weares and teares less, antitheft, anti-drilling gear-like is arranged cylinder lock more.

The purpose of this utility model can realize by following measure:

A kind of gear-like is arranged cylinder lock more, contains tapered end pipe, lock core pipe, core bar etc.; Be provided with 4-6 longitudinal fluting at lock core pipe inwall upper edge 1-3 bar radial center line symmetry and become profile of tooth, in groove, be placed with long and short, half logical pellet shot from a slingshot respectively; The groove depth of lock core pipe is the 1-2 millimeter, and groove width is the 1-1.5 millimeter; Used gear-like is arranged the key of cylinder lock more, contain the shank of the key and key pipe, it is corresponding with the groove of lock core pipe to be provided with the vertical boss of 4-6 at key pipe outer wall upper edge 2-3 bar radial center line symmetry, the boss height is the 1-2 millimeter, wide is the 1-1.5 millimeter, and it is corresponding with long and short, partly logical pellet shot from a slingshot respectively to be provided with thread form on boss.

The purpose of this utility model also can realize by following measure:

The short pellet shot from a slingshot that gear-like is arranged in the cylinder lock more can replace with steel ball; The maximum cusp difference of used key thread form is the gap width of lock core pipe groove groove top to core bar.

The utility model has following advantage compared to existing technology:

1, is provided with groove in the lock core pipe of the present utility model, increased and be placed with the position of pellet shot from a slingshot and the gap of core bar in the lock core pipe, thereby improved the long and short varied number of pellet shot from a slingshot in the lock core pipe, promptly improved size of key.

2, the utility model is used is provided with boss on the key, and is provided with the key thread form on boss, thereby has strengthened the intensity at key thread form position.

3, the utility model adopts steel ball to replace short pellet shot from a slingshot, and has replaced the tack pellet shot from a slingshot of long marble upper end with steel ball, thereby can reduce the wearing and tearing of key and pellet shot from a slingshot.

4, the utility model is antitheft, anti-drilling, easily opens and good hand touch.

5, the utility model is applicable to various door locks, padlock, automotive lock, safety cabinet lock, storage lock etc.

Concrete structure of the present utility model is provided by the following drawings:
