CN2089500U - Rotary disk structure lock - Google Patents

Abstract

The utility model relates to a rotary disk structure lock, which is composed of a lock core, a double lock tongue, a tooth form rod, etc., formed by the overlapping of a lock body, a lock beam, and multiple rotary plates. In virtue of adopting the structure of the double lock tongue, the lock beam can endure more static tensile force after locking; the lock core has not a ball hole and has good anti-pry performance. Inside the lock core, no ball generates the pressure for a key; the key can be conveniently inserted and pulled out. The gap angle of each rotary plate is different in the lock core, and the tooth form of the key has multiple changes.

Description

Rotary disk structure lock

The utility model relates to the lock of opening with screw key.

In the prior art field, use lock cylinder structure lock widely, all be to utilize cylindric metal pellet shot from a slingshot to hinder foreign matter to unblank, have only the obstruction of getting rid of cylindric metal pellet shot from a slingshot with the suitable interior rotation of key insertion lock core to reach and open the purpose of locking.But the suffered quiet pulling force of the pellet shot from a slingshot hole of traditional cylinder lock or lock bridge is greatly all easily pried open inadequately, in a sense, since perfect inadequately on the structure, there is the factor of safety inadequately.

The purpose of this utility model is the lock core of traditional cylinder lock to be used instead a plurality of rotating disks be formed by stacking, and utilizes the different corners of each rotating disk and reaches the unlatching and the closure function of lock.

The technical solution of the utility model is: it mainly is made of lock body, lock bridge, lock core, dead bolt etc.Lock core in the lock body is formed by stacking by a plurality of rotating disks, the endoporus of each rotating disk all has key and forms a groove each other, each rotating disk outside cylinder bottom has otch, on the circumference on otch top, have the breach that angle has nothing in common with each other, rotational lock core can make breach aim at the corresponding groove of profile of tooth bar or convex shoulder is snapped in the corresponding groove of profile of tooth bar, two inclined-planes of profile of tooth bar one end contact with an end of two dead bolts respectively, the other end of two dead bolts can be respectively and two groove clutches of lock bridge, bull stick one end boss in the lock body contacts with profile of tooth bar groove, and other end flange is positioned under the convex shoulder of lock bridge bottom.Lock core generally is to be formed by stacking by 3～7 rotating disks.

The advantage that the utility model and the phase-locked ratio of the lock cylinder structure of prior art have:

1. owing to adopt the double lock tongue structure, make lock bridge bear quiet pulling force after sealed and strengthen, non-marble hole in the lock core simultaneously, the pick-proof performance is good.

2. owing to do not have pellet shot from a slingshot that key is produced pressure in the lock core, the insertion of key and extract stressed minimizing, plug makes things convenient for.

3. the breach angle of forming each rotating disk of lock core has nothing in common with each other, and the rotational angle of suppose rotating disk is 120 °, with per 12 ° be a grade, adopt lock core to form by 5 rotating disks, then the variation of key thread form can reach 10 ⁵=100,000 kind.

Below in conjunction with accompanying drawing the utility model is further described.

The structural representation of Fig. 1, turntable structure lock;

Fig. 2, rotating disk upward view;

Fig. 3, rotating disk outline drawing;

Fig. 4, Key structure figure;

Fig. 5, bull stick structure chart.

As Fig. 1, Fig. 3, shown in Figure 4, when the cylindrical key 17 with a plurality of projections is inserted the groove 12 of being made of the keyhole of lock core corresponding number rotating disk 2, key 17 is during to a certain angle, locating convex block 18 on the key is stuck in the groove of keyhole, meanwhile, key has driven rotating disk 2 and has rotated different angles, on the circumference of otch 15 top rotating disks 2, have angle breach inequality 13 and all aim at profile of tooth bar 8, one inclined-plane of its upper end is subjected to the effect of oblique dead bolt 5 upper springs 4 to make oblique dead bolt 5 inside indentations, pressure moves downward profile of tooth bar 8, lock bridge 6 is oppressed spherical dead bolt 7 inside indentations under the effect of lower end spring 11, lock bridge 6 pops up lock and is opened.Alignment pin 9 rises in the lock bridge groove decides Cheng Zuoyong, in case lock bridge is deviate from lock body 1.

As Fig. 1, Fig. 2, shown in Figure 5, when compression lock bridge 6, lock bridge 6 convex shoulders are pressed to the boss of bull stick 10 1 ends, make bull stick 10 produce counter-rotating, the boss of bull stick 10 other ends is pressed to the groove of profile of tooth bar 8, force profile of tooth bar 8 to move upward, replying pellet shot from a slingshot 3 simultaneously is subjected to the effect of spring force to insert bullet groove 16, make rotating disk 2 produce opposite spin, rotating disk 2 otch 15 top convex shoulders 14 snap in respectively in the groove of corresponding profile of tooth bar 8, at this moment two inclined-planes of profile of tooth bar 8 ends are pressed to spherical dead bolt 7 and oblique dead bolt 5 respectively and are stuck in two grooves of lock bridge 6 and are lockable, and key 17 reversed turnings take out key 17.

Claims (2)

1, a kind of turntable structure lock, it comprises lock body, lock bridge, lock core, dead bolt etc., feature of the present utility model is: the lock core in the lock body [1] is formed by stacking by a plurality of rotating disks [2], the endoporus of each rotating disk [2] all has key [12] and forms a groove mutually, each rotating disk [2] outside cylinder bottom has otch [15], have the breach [13] that angle has nothing in common with each other on the circumference on otch [15] top, rotational lock core can make the corresponding groove of breach [13] and profile of tooth bar [8] aim at or convex shoulder is snapped in the corresponding groove of profile of tooth bar [8], two inclined-planes of profile of tooth bar [8] one ends respectively with two dead bolts [7], [5] a end contacts, two dead bolts [7], [5] the other end respectively with two groove clutches of lock bridge [6], bull stick [10] one end boss in the lock body [1] contact with profile of tooth bar [8] groove, and other end flange is positioned under the convex shoulder of lock bridge [6] bottom.
