Abstract

The utility model relates to a modified insurance door lock, which is composed of a master lock and two auxiliary locks. When external key is used to switch master lock via the motion between handspike and driven link meanwhile auxiliary lock is caused to be switched, so that the separated latch with three points is formed on doorframe. Consequently, the utility model has a very high latch intensity and an insurance effect.

Description

Separating type door lock with three bolt

The utility model is a kind of door lock of improved daily living article.

No matter existing door lock is single tongue lock or two tongue lock, all is mounted among the same lock box.Dead bolt is stretched the people and is contained within the keeper on the doorframe, to whole doorframe, only is that locking is lived a bit, and not only intensity difference, and locking point exposes, and still easily by stranger's strong destruction, loses the effect of security insurance.

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of separate type three dead bolt door locks of designing, can on doorframe, form three locking points, and wherein two locking points do not expose, thereby improve locking intensity greatly, reach the effect of security insurance.

The purpose of this utility model realizes by following way: separate type three dead bolt door locks are by a main lock, on, following two pair lock composition, open, when closing the dead bolt of main lock, drive the interior lever of secondary lock by drive link, the dead bolt of secondary lock is also opened, close, such three dead bolts stretch into or withdraw from keeper separately simultaneously, main lock can be as required with secondary lock, becoming at 3 by different distances is distributed on the doorframe, increased the locking intensity of door, and three dead bolts can not be pried open by foreign matter simultaneously, should not be by stranger's strong destruction, thus play the effect of security insurance.

The utility model is simple in structure, and locking intensity is big, and is safe and reliable, is easy to promote the use of.

Below in conjunction with accompanying drawing the separate type three dead bolt door locks that the utility model proposed are further described:

Fig. 1 is the structural representation of the separate type three dead bolt door locks that propose of the utility model.

As seen from Figure 1, separate type three dead bolt door locks are by main lock (A), on, following secondary lock (B) (C) three parts is formed, ((C) structure is identical for secondary lock (B), only represent among Fig. 1) with (B), main lock (A) is by lock box (4), drive link (3), disk (2), helix guide groove (1) on the disk (2), shifting block (6), bearing pin (7), dead bolt junction plate (5), dead bolt (8), keeper (9), lock body base plate, tapered end transmission bar compositions such as (not drawing among these two figure), secondary lock (B) or (C) by lock box (10), lever (11) dead bolt junction plate (12), dead bolt (13), keeper compositions such as (14), when the keyhole of the external application key main lock of insertion (A) turns clockwise, tapered end transmission bar is also turned clockwise, stretch in the slot of disk (2) owing to tapered end transmission bar again, disk (2) is also turned clockwise, when turning clockwise 180 ° the time, shifting block (6) the promotion dead bolt junction plate (5) that is contained on the disk (2) moves to left, in moving to left, the dead bolt (8) that makes the master lock (A) contracts, door is opened, because the bb of the helix guide groove (1) on the disk (2) ¹Section is a semi arch, so drive link this moment (3) does not move, thereby pair is locked (B) or dead bolt (C) (13) is motionless, all be recessed in the lock box (10), when the external application key is rotated counterclockwise 360 °, disk (2) also is rotated counterclockwise 360 °, helix guide groove (1) on the disk (2) moves down bearing pin (7), bearing pin (7) drives drive link (3) again and moves down, moving down of drive link (3) makes lever (11) motion, secondary lock (B) or dead bolt junction plate (12) (C) are all moved to right, dead bolt (13) also all moves to right and stretches in the secondary lock keeper (14), meanwhile, the dead bolt junction plate (5) that shifting block (6) on the disk (2) also promotes main lock (A) moves to right, dead bolt (8) is also moved to right stretch into main like this lock (A) in the main lock keeper (9), secondary lock (B) or (C) all be locking states reaches the effect of 3 lockings insurances.

Otherwise as, the external application key turns clockwise 360 °, pair can be locked (B) or dead bolt (C) (13) and contract in moving to left earlier, when the external application key continues to turn clockwise 180 ° again, contract in the dead bolt (8) of main lock (A) moves to left, 3 lockings are removed, and door is opened.

Claims

1, separate type three dead bolt door locks are made up of lock box (4), dead bolt junction plate (5), dead bolt (8), keeper (9) and lock body base plate, tapered end transmission bar etc., it is characterized in that:

A, door lock divide between main lock (A), secondary lock (B), (C) three parts, the major and minor lock and connect by drive link (3);

B, main lock (A) have disk (2), bearing pin (7), the drive link (3) of band helix guide groove (1), during disk (2) rotation, helix guide groove (1) also rotates and promotes bearing pin (7) and makes the upper and lower motion of drive link (3);

C, secondary lock (B) or (C) each is made up of lock box (10), lever (11), dead bolt junction plate (12), dead bolt (13), lever (11) then drives and makes dead bolt junction plate (12) move left and right by drive link (3).
