Abstract
A door lock is capable of locking and positioning doors, can smoothly unlock the doors under certain external force on the doors, and is particularly adaptable to remote control gates and automatic open doors. In the door lock, the front end of a bolt is equipped with rollers, roller chutes are arranged inside a door frame or a casing, the chutes are provided with a proper inclination, and a bolt hole is concave.
Description
Affiliated technical field:
The utility model relate to a kind of can be with door lock tight and location, and masterpiece is used for also the door smooth opening to be particularly useful for remote control gate, automatic opening door when last outside.
Background technology
At present, common door lock is just made the inboard beveling of dead bolt, the outside to face directly, and the dead bolt telescopic hole is the square type.Since there is the gap between dead bolt and the dead bolt hole, can not door lock is tight; In addition, masterpiece is used for when last outside, and there are friction in dead bolt and dead bolt hole, and it is just very difficult to open the door.
Summary of the invention
Can not and external force be arranged as the time spent difficulty of opening the door with the door tight closing in order to overcome common door lock, the utility model provides a kind of dead bolt and dead bolt slideway of door lock, and is can be with door lock tight and locate, have external force to act on and also door can be opened when last.
The utility model is to deal with problems the technology side that adopted by being: the front end of dead bolt is installed roller, and the contact surface of dead bolt slideway and roller is designed to have the inclined-plane of suitable angle, capable of expansion and contraction for making dead bolt, the telescopic hole of dead bolt is designed to matrix.Like this, after door is shut since the roller on the dead bolt contact with the slide ramp zero clearance, so can be tightly and fix on this position door motionless with door lock.When opening the door,, help roller to roll, and rolling frictional resistance is very little, therefore, even the effect of external force is arranged on door, also can open the door smoothly because of the contact surface of roller and roller slideway has certain inclination angle.
The beneficial effects of the utility model are: after closing to the doorstep, can be with door lock tight and fix on this position; Even there is certain external force roof door also can open the door smoothly when opening the door.And it is simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the three-view diagram of the utility model dead bolt.
Fig. 2 is the three-view diagram of dead bolt slideway and dead bolt hole.
Fig. 3 is the sectional view of embodiment.
Among the figure, 1, roller; 2, dead bolt; 3, roller slideway; 4, dead bolt telescopic hole; 5, main lock body; 6, door; 7, doorframe.
Among Fig. 1, roller (1) is installed in the front end center of dead bolt (2).
Among Fig. 2, dead bolt telescopic hole (4) is designed to matrix, it is capable of expansion and contraction to be convenient to dead bolt (2). Roller slideway (3) design For becoming suitable inclination angle with roller (1) horizontal direction.
The specific embodiment
In Fig. 3, main lock body (5) is fixed as one with door (6), has dead bolt hole (4) on doorframe, and along roller slideway (3) is installed in the dead bolt hole doorframe, roller (1) is installed in the front end center position of dead bolt (2) by roller shaft; Dead bolt slideway (3) one ends link to each other with the minimum point of matrix dead bolt hole (4), and the other end links to each other with doorframe (7) inwall and forms suitable inclination angle.When dead bolt (2) eject in by main lock body (5) enter lockhole (4) after, roller (1) both advanced along slideway (3), eject fully until dead bolt, because the effect at roller slideway (3) inclination angle, can be pressed on slideway (3) after dead bolt ejects goes up and certain lateral displacement, door (6) locking and location is the most at last arranged.When opening the door, between roller (1) and roller slideway (3) certain angle is arranged and rolling frictional resistance is very little, power dead bolt (2) that therefore need only be very little will be retracted in the main lock body smoothly, even when effect has external force on door, also can open the door smoothly.
Claims (3)
1. a door lock can be opened the tight also location of door lock when opening the door smoothly with door.It is characterized in that: the front end of dead bolt is equipped with roller, and the roller slideway is arranged in the dead bolt hole.
2. door lock according to claim 1 is characterized in that: the front end of dead bolt is provided with groove, and roller is installed in the groove by axle, and the roller outer rim is protruded.
3. door lock according to claim 1, roller slideway be installed in doorframe or the housing that is fixed together with doorframe in, the direction of motion of slideway and dead bolt has suitable angle.
