Abstract
The utility model relates to a closing limiting device of a spring lock, comprising a door body (1); the door body (1) is internally provided with a lock hole (6) with horizontal displacement; the lock hole (6) is internally provided with a spring bolt (5) of the spring lock in a sliding manner; the door body (1) is also internally provided with a guiding groove (2) which is vertical to a lock hole (6) in displacement and is positioned above the lock hole (6); the lower end of the guiding groove (2) is communicated with the lock hole (6); the guiding groove (2) is internally provided with a limiting plate (4) which can slide up and down; and the upper end of the limiting plate (4) is connected with a hook (3) for suspending a key. When the limiting plate is operated, the key is carried, and a door can be automatically locked. Therefore, the closing limiting device solves the problem that a person forgets to carry the key when going out and is locked out of the house.
Description
(1), technical field
Thereby the utility model relates to the isolated plant that a kind of latch bolt position by the restraining spring lock limits automatic blocking, and this device mainly is installed on the security door.
(2), background technology
Existing security door generally adopts latch lock, and dead bolt ejects automatically door lock is closed at closing time.A lot of people often leave behind key when going out, and after shutting the door after you oneself are locked in outside the room.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of latch lock restriction shutoff device is provided, and has the locking limitation function, and dead bolt can't eject when leaving behind key, and then solves the problem that existing lockset does not have the automatic blocking limiting mechanism to cause.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of latch lock restriction shutoff device, comprise a body, in the door body, offer the lock of level trend, be slidingly fitted with dead bolt in the lockhole, it is characterized in that: also offer trend and move towards orthogonal with lockhole and be positioned at gathering sill above the lockhole in the door body, this gathering sill lower end is communicated with lockhole; Can slide up and down to be equipped with limiting plate in gathering sill, the upper end of this limiting plate is connected with the hook that is used to hang key.
Good effect of the present utility model is: carry key in passing during the operation limiting plate, door can automatic blocking.Therefore solved because of going out and left behind key the problem that oneself locks in outdoors.The utility model also has simple in structure, the characteristics of dependable performance.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
(5), the specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, present embodiment comprises a body 1, offers the lockhole 6 of level trend in door body 1, is slidingly fitted with the dead bolt 5 of latch lock in the lockhole 6.Also offer trend and move towards orthogonal with lockhole 6 and be positioned at gathering sill 2 above the lockhole 6 in door body 1, these gathering sill 2 lower ends are communicated with lockhole 6.Can slide up and down to be equipped with limiting plate 4 in gathering sill 2, the upper end of this limiting plate 4 is connected with the hook 3 that is used to hang key.
Upwards pull up limiting plate 4, dead bolt 5 can eject, and realizes the locking of door body 1; Unclamp limiting plate 4, it blocks dead bolt 5 latter can't be ejected by the downward landing of deadweight, the restriction locking.
When using the utility model, generally key is hung on the described hook 3.Carry key when upwards pulling up limiting plate 4 when going out smoothly, this moment, door can locking, that is to say, inoperation limiting plate 4, door can not be by automatic blockings, solved leave behind because of going out key with oneself about outdoors problem.
Claims (1)
1. a latch lock limits shutoff device, comprise a body (1), in door body (1), offer the lock (6) of level trend, be slidingly fitted with the dead bolt (5) of latch lock in the lockhole (6), it is characterized in that: also offer the gathering sill (2) that trend is moved towards orthogonal with lockhole (6) and is positioned at lockhole (6) top in door body (1), this gathering sill (2) lower end is communicated with lockhole (6); Can slide up and down to be equipped with limiting plate (4) in gathering sill (2), the upper end of this limiting plate (4) is connected with the hook (3) that is used to hang key.
