Description

Position, four directions door lock

The utility model relates to lock, key, the particularly lock of usefulness key.

Now, cell gate to the room, the locking function of the door of security door and public place is had higher requirement, existing lock, as two insurances, though the locks of three insurances are the function that can be relevant can be barred up by dead bolt to the doorstep, but it can only have locking bolt in an orientation, and can not be on door, down, a left side, the right side all has locking bolt to stretch out and door lock is lived, and is very dangerous, though and the lock of security door can three orientation be promptly gone up, down, the side of opening the door can have locking bolt to stretch out and lock, but promptly use key to drive lock, also must just can make locking bolt withdrawal, just can open door with the hand swing handle, at closing time also must with the hand swing handle just can shut the door or bolt on, therefore very inconvenient, and in the hinge side of door, owing to there is not locking bolt, intensity is low, easily destroyed, also dangerous.

The purpose of this utility model provides a kind of easy to operate, safe and reliable position, four directions door lock that can have locking bolt to stretch out at upper and lower, the side of opening the door, the hinge side four direction of door leaf.

Another purpose of the present utility model provides position, four directions door lock a kind of as above-mentioned and have dead bolt in the side of opening the door.

The purpose of this utility model realizes by following technical scheme, position, four directions door lock has lock housing, panel, the side chain bolt movably opens the door in lock housing, tapered end, it is characterized in that having projection on the tapered end, has the groove that cooperates with this projection on the locking bolt, when tapered end is used key turns, can handle that locking bolt stretches out or the indentation lock housing, also have triangle revolving part and the semicircle revolving part that drives by locking bolt in the lock housing, they all can be around the axle rotation of self, and the triangle revolving part drives in lock housing movably downside pin, pin and hinge side pin on the semicircle revolving part drives in lock housing movably, thereby stretch out or during indentation when the side chain bolt that opens the door, on, down, the hinge side pin also stretches out or indentation simultaneously, and the locking bolt that drives everywhere pins Men Zaisi orientation, also has card that locks the side chain bolt that opens the door and the spring that suppresses card in the lock housing, make locking bolt when locking or withdrawal, can not be shifted.

In lock housing, can have movably dead bolt, the pulling dead bolt makes it to be in the spring of normal extended position and the handle axle sleeve of control dead bolt withdrawal, can be at the equal jug in the medial and lateral of door, also jug in door only moves dead bolt and also have in the lock housing, the S shape connecting rod of being handled by tapered end, must could withdraw dead bolt and opening the door this moment outdoors with key, increased by one and locked gear.

Position, four directions of the present utility model door lock, upper and lower, the side of opening the door and the hinge side of Men Zaimen can be pinned door simultaneously, increased the locking of hinge side direction, thereby increased the safety of door, and can have dead bolt simultaneously, can increase a locking gear again, with same key, can handle locking bolt and dead bolt, easy to operate, safe and reliable.

Below, in conjunction with the accompanying drawings and embodiments position, four directions of the present utility model door lock is described in detail.

Fig. 1 is that position, four directions of the present utility model door lock is installed in the schematic diagram on the door leaf;
