Description
Affiliated technical field
The utility model relates to a kind of doorframe lock, and particularly a kind of do not having the no knocking door case of tapered end knocking door case to lock at closing time.
Background technology
At present, the tapered end of known doorframe lock all for stretching out outside the door limit, can produce the bump vibration to doorframe at closing time when door is in opening, and so both easy damage doorframe can produce impact noise again.
Summary of the invention
The purpose of this utility model is that proposition is a kind of is not having the no knocking door case of tapered end knocking door case to lock at closing time.
The technical scheme that its technical problem that solves the utility model adopts is: be contained in and be provided with a fixing lock shaft seat and a driver chuck axle in the door lock shell on the limit.The lock shaft kink is in the lock shaft seat, and the head of lock shaft is provided with the tapered end that magnet is housed, the locating ring that cooperates with lock shaft seat left surface, and the afterbody of lock shaft is set with and pushes away lock ring, compression spring and tail ring.Kink has a rotating driver chuck on the driver chuck axle, and driver chuck is provided with push away lock ring dead man and one that push away that lock ring abuts against and is used for the pin that connects with push rod, and moving up and down of push rod controlled by key.Be provided with a tapered end groove with the corresponding doorframe of door lock head limit, the magnet that is fixed on the doorframe is housed in the groove.At closing time, the magnet in the door frame slot holds the magnet on the tapered end, and tapered end puts in the tapered end groove, both door lock is lived; When unblanking and open the door, the rotary door key will push away on the push rod, drives dead man on the driver chuck and stirs to the right and push away lock ring, and bearing pin is moved to right, and the tapered end withdrawal is entered in the limit, and both can be implemented in does not have the tapered end knocking door case at closing time.
The beneficial effects of the utility model are, and are simple in structure, reliable in action, the vibration and the noise that do not have the tapered end knocking door case to produce at closing time.
