1. A door lock for a sectional door, said sectional door comprising a door leaf and a door frame which are hinged to each other, said door leaf being selectively rotatable horizontally relative to the door frame in a closing direction for closing the sectional door or rotatable relative to the door frame in an opening direction opposite to the closing direction for opening the sectional door, characterized in that: comprises a lock tongue arranged on a door leaf and a lock hole arranged on a door frame; the door leaf can selectively enable the lock tongue to penetrate into the lock hole through rotation along the closing direction or enable the lock tongue to be separated from the lock hole through rotation along the opening direction;

the lock tongue comprises a stopping part and a hinge part extending along the horizontal direction perpendicular to the rotation center line of the lock tongue, and when the lock tongue is positioned in the lock hole, the hinge part is closer to the lock hole than the stopping part along the opening direction;

The lock ring can naturally fall down and is hung on the hinge part; when the locking ring is in a natural falling state, the locking ring can selectively rotate around the hinge part along a first direction to move to a first position where the locking ring can pass through the locking hole along with the locking tongue, or rotate around the hinge part along a second direction opposite to the first direction to move to a second position where the locking ring abuts against the abutting part; when the lock ring is in a natural falling state or in a second position, the lower edge of the lock ring is positioned below the lower edge of the lock hole.

2. A door lock for a sectional door as claimed in claim 1, wherein: the pivot part is in a shaft shape.

3. A door lock for a sectional door as claimed in claim 2, wherein: the cross section of the pivot part is circular.

4. a door lock for a sectional door as claimed in claim 1, wherein: the stopping part is in a bent shaft shape, and two ends of the stopping part are respectively connected with the pivot part.

5. A door lock for a shutter door according to claim 4, characterized in that: the hinge part and the stopping part are integrally formed.

Technical Field

The invention relates to the technical field of enclosure structures, in particular to a door lock for an enclosure movable door.

Background

With the continuous development of infrastructure in China, the requirement of construction standardization of construction sites is higher and higher, and various construction products are continuously pushed out. And the enclosure structure is used as an essential important component in construction engineering, and has a good development prospect. For the existing enclosure structure, a sliding movable door is often left for the business personnel to enter and exit. However, at present, for the movable door of the enclosure, no matched special lock is provided, and the movable door is mainly locked by using a purchased common door lock. When the door is opened and closed each time, the door lock needs to be opened by a key, which is complicated and inconvenient.

disclosure of Invention

In summary, the technical problems solved by the present invention are: the door lock is convenient to lock and unlock and is suitable for the enclosure movable door.

The scheme adopted by the invention for solving the technical problems is as follows:

A door lock for a sectional door, said sectional door comprising a door leaf and a door frame which are hinged to each other, said door leaf being selectively rotatable horizontally relative to the door frame in a closing direction for closing the sectional door or rotatable relative to the door frame in an opening direction opposite to the closing direction for opening the sectional door, characterized in that: comprises a lock tongue arranged on a door leaf and a lock hole arranged on a door frame; the door leaf can selectively enable the lock tongue to penetrate into the lock hole through rotation along the closing direction or enable the lock tongue to be separated from the lock hole through rotation along the opening direction;

The lock tongue comprises a stopping part and a hinge part extending along the horizontal direction perpendicular to the rotation center line of the lock tongue, and when the lock tongue is positioned in the lock hole, the hinge part is closer to the lock hole than the stopping part along the opening direction;

The lock ring can naturally fall down and is hung on the hinge part; when the locking ring is in a natural falling state, the locking ring can selectively rotate around the hinge part along a first direction to move to a first position where the locking ring can pass through the locking hole along with the locking tongue, or rotate around the hinge part along a second direction opposite to the first direction to move to a second position where the locking ring abuts against the abutting part; when the lock ring is in a natural falling state or in a second position, the lower edge of the lock ring is positioned below the lower edge of the lock hole.

further, the hinge part is in a shaft shape.

Furthermore, the cross section of the hinge part is circular.

Furthermore, the stopping part is in a bent shaft shape with two ends respectively connected with the pivot part.

Further, the hinge part and the stopping part are integrally formed.

In conclusion, due to the adoption of the technical precaution, the invention has the beneficial effects that: according to the invention, the lock hole and the lock tongue which are matched with each other are arranged on the movable door of the enclosure, so that the locking and the unlocking between the door frame and the door leaf in the movable door of the enclosure are realized, and the movable door can effectively replace a common door lock in the traditional mode; compared with the common door lock in the traditional mode, the door lock structure provided by the invention is more convenient and faster in opening and locking, and is particularly suitable for construction sites with frequent access.
