The traditional interlocking mechanism has the defects of complex structure, high failure rate, difficult maintenance and the like. Accordingly, the present utility model further improves upon the door closing interlocking mechanism, and referring to fig. 1 to 2, a door closing interlocking mechanism of the present utility model makes the following embodiments:
In some embodiments, a door closing interlock mechanism is applied to a double door comprising a first door 500 and a second door 600, the first door 500 and the second door 600 being a left door and a right door, respectively, in other embodiments, the first door 500 and the second door 600 may also be a right door and a left door, respectively.
The pulling rod 100 is provided with a central shaft 200, the central shaft 200 is fixed on a doorframe, the pulling rod 100 is rotatably arranged around the central shaft 200, two ends of the pulling rod 100 are respectively provided with a gravity block 300 and a locking rod 400, the locking rod 400 is correspondingly provided with a clamping groove 610 arranged at the top of the second door 600, and the gravity block 300 is arranged at the top of the first door 500.
In the double door condition, the second door 600 is closed, the top edge of the first door 500 is closed again, and the gravity block 300 acts on the top edge of the rear door, so that the pulling rod 100 rotates through the central shaft 200 to clamp the door top clamping groove 610 of the second door 600, and the double doors are interlocked. When the door is opened, the first door 500 is opened first, the pulling rod 100 sags due to gravity, the locking rod 400 is separated from the locking groove 610, and the second door 600 is opened. The door opening sequence is limited, the interlocking function is achieved, and the structure is simple. When the door is opened, the first door 500 needs to be opened first to open the second door 600, so as to meet the door opening requirement of special occasions. For example, when the second door 600 is a normally closed door, a person can be prevented from opening the second door 600 by mistake.
Further improved, the double door comprises a first door 500 and a second door 600, the gravity block 300 is arranged at the top of the first door 500, and the clamping groove 610 is arranged at the top of the second door 600.
Further improved, the gravity block 300 has a cylindrical shape, so as to facilitate the opening and closing of the first door 500. When the first door 500 is opened, the gravity block 300 rubs against the top of the first door 500, so that the door needs to be opened against the friction force, and the contact surface with the top of the first door 500 is reduced in a cylindrical shape, thereby reducing the friction force, and facilitating the opening of the first door 500. Meanwhile, when the first door 500 is closed, the gravity block 300 needs to be pushed upwards, and the arc surface of the cylindrical block plays a certain guiding role, so that the first door 500 is closed conveniently. In other embodiments, the gravity block 300 may have a shape of a cake or a sphere, which is not particularly limited in the present utility model.
Further improved, the outer side of the gravity block 300 is wrapped with an anti-collision layer, and the anti-collision layer is an elastic layer. The anti-collision layer can be made of plastic or rubber materials.
Further improved, the device also comprises a mounting plate 700, the central shaft 200 is arranged on the mounting plate 700, the pulling rod 100 is arranged on the mounting plate 700 in a sliding manner, so that the pulling rod 100 rotates on the same plane, and the failure of the interlocking structure is prevented. The failure condition is a condition in which the lock lever 400 cannot be aligned with the card slot 610, and thus cannot be locked. Wherein, the pulling rod 100 is slidably disposed on the mounting plate 700, so as to have a better anti-collision effect. Specifically, the mounting plate 700 is provided with an arc-shaped chute, the pulling rod 100 is rotationally provided with balls, and the balls slide on the chute slideway to play a role in limiting the pulling rod 100 to rotate on the same plane. In other embodiments, the chute is provided with a flange, and the ball is snapped into the flange.
In other embodiments, the gravity block 300 and the lock bar 400 are provided with sliding parts slidably provided on the mounting plate 700, so that the central shaft 200 rotates on the same plane, preventing the failure of the interlocking structure.
In order to limit the movement track of the sliding portion, the mounting plate 700 is provided with an arc-shaped slot, the sliding portion is slidably disposed in the arc-shaped slot, and the sliding portion is rotatably disposed in the gravity block 300 or the lock lever 400. The sliding portion may comprise a planar ball bearing or a ball.
Further improved, the lock lever 400 is vertically adjustable to the pulling rod 100. The position of the lock lever 400 is adjusted according to the actual installation situation, so that the second door 600 is conveniently opened. Specifically, the locking bar 400 is threadedly coupled to the pulling bar 100. The length of the downward extension of the lock lever 400, i.e., the depth of the engagement, is adjusted according to the width of the double door.
While the preferred embodiments of the present utility model have been illustrated and described, the present utility model is not limited to the examples, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present utility model, and these equivalent modifications and substitutions are intended to be included in the scope of the present utility model as defined in the appended claims.
