Detailed Description

The present invention provides a door lock for a movable door of an enclosure, which will be described in detail with reference to the accompanying drawings and embodiments.

Example 1

As shown in fig. 1 to 4, a door lock for a movable door includes a door leaf 1 and a door frame 2, which are hinged to each other, wherein the door leaf 1 can selectively rotate horizontally relative to the door frame 2 in a closing direction to close the movable door, or rotate relative to the door frame 2 in an opening direction opposite to the closing direction to open the movable door, and includes a lock tongue 3 disposed on the door leaf 1 and a lock hole 4 disposed on the door frame 2; the door leaf 1 can selectively enable the bolt 3 to penetrate into the lock hole 4 through rotation along the closing direction, or enable the bolt 3 to be separated from the lock hole 4 through rotation along the opening direction;

The bolt 3 comprises a stopping part 32 and a hinge part 31 extending along a horizontal direction perpendicular to a rotation center line of the bolt 3, and when the bolt 3 is positioned in the lock hole 4, the hinge part 31 is closer to the lock hole 4 than the stopping part 32 along an opening direction;

the lock ring 5 can naturally fall and is hung on the hinge part 31, when the lock ring 5 is in a natural falling state, the lock ring 5 can selectively rotate around the hinge part 31 along a first direction to move to a first position which can pass through the lock hole 4 along with the bolt 3, or rotate around the hinge part 31 along a second direction opposite to the first direction to move to a second position which is abutted against the abutting part 32; when the shackle 5 is in the natural falling position and in the second position, the lower edge of the shackle 5 is below the lower edge of the locking hole 4.

the movable door in this embodiment 1 is a push-pull type movable door, i.e., the movable door can be opened by a user pushing or pulling the door leaf 1 with respect to the door frame 2. As shown in fig. 1, the above opening direction means: the door leaf 1 rotates along the horizontal direction to open the movable door; as shown in fig. 2, the closing direction corresponds to: the door leaf 1 can be rotated along the horizontal direction to close the movable door. It will be appreciated that the closing direction is opposite to the opening direction.

And along with the rotation of the door leaf 1 in the opening direction or the closing direction in the movable door, the lock tongue 3, the lock ring 5 and the lock hole 4 realize the locking or the opening between the door leaf 1 and the door frame 2. Specifically, as shown in fig. 3 and 4, in the locked state, the shackle 5 is positioned in the lock hole 4, and the shackle 5 is hung on the hinge portion 31 and is in a naturally hanging state. At the moment, if someone pushes the door leaf 1 to the opening direction to drive the whole lock tongue 3 to rotate to the opening direction, the lower edge of the lock ring 5 is positioned below the lower edge of the lock hole 4, so that the lock ring 5 can not pass through the lock hole 4; meanwhile, when the bolt 3 is in the lock hole 4, the pivot portion 31 is closer to the lock hole 4 than the stopping portion 32 along the opening direction, so the lock ring 5 can make the lock ring 5 rotate to the second position thereof towards the second direction by abutting against the end surface of the lock hole 4, at this time, the lower edge thereof is also positioned below the lower edge of the lock hole 4, but because the stopping portion 32 provides stopping force to the lock ring 5 at this time, the lock ring 5 does not rotate around the pivot portion 31 any more, the bolt 3 is difficult to move relative to the lock hole 4, and the bolt cannot be separated from the lock hole 4, thereby realizing the limit between the door frame 2 and the door leaf 1. As shown in fig. 5, when the movable door needs to be opened normally, a user only needs to toggle the lock ring 5 with a hand to rotate the lock ring to the first position around the pivot along the first direction, so that the locking and the unlocking between the door frame 2 and the door leaf 1 in the enclosure movable door are realized, and the lock ring can effectively replace a common door lock in the traditional mode; compared with a common door lock in a traditional mode, the door lock structure provided by the invention omits a key assembly, is more convenient and faster to open and lock, and is particularly suitable for construction sites with frequent access.

meanwhile, it can be understood that, since the lock ring 5 is in a ring shape and is hung on the hinge portion 32, and the lower edge of the lock ring is located below the lower edge of the lock hole 4 in the naturally falling state and the second position, the lower edge of the lock ring is always located below the lower edge of the lock hole 4 in the process of moving from the naturally falling state to the second position.

When the movable door needs to be closed and locked, as shown in fig. 6, the user rotates the door leaf 1 in the closing direction to insert the bolt 3 into the door frame 2, wherein, when the movable door is closed, the abutting portion 32 is closer to the lock hole 4 than the hinge portion 31 in the closing direction, so the lock ring 5 only rotates to the first position in the first direction under the action of the end surface of the lock hole 4; at this time, the tongue 3 can be freely inserted into the lock hole 4.

Wherein the first direction is: as shown in fig. 3, the counterclockwise direction around the hinge portion 31, and the second direction corresponds to the clockwise direction around the hinge portion 31, and the natural falling refers to: the locking ring 5 is in a balanced state receiving only the self weight and the supporting force of the hinge portion 31, and its lower edge is at the lowest position. In the preferred embodiment, in the present embodiment 1, the hinge portion 31 has a shaft shape, and more specifically, has a circular cross section. This arrangement allows the locking ring 5 to be naturally returned to the initial hanging state without being subjected to an external force other than the supporting force of the hinge portion 31.

More specifically, in this embodiment 1, the stopping portion 32 is in a bent shaft shape with two ends respectively connected to the hinge portion 31, so that it and the hinge portion 31 enclose a ring buckled with the locking ring 5, thereby avoiding the loss of the locking ring 5. In addition, the hinge portion 31 and the stopping portion 32 are integrally formed to enhance the structural strength.
