TH2979A3 - Automatic door with base lock - Google Patents

Abstract

Based on this invention, the base-lock automatic door is characterized by the Opening and closing the door will rely on the nature of the convection from the bottom door edge. By bringing up the door edge to open The door or take it down to close the door It may use a long rod, all threaded, use a chain, or use a sling to be installed all the way. Left and right side with a base lock set attached to the lower edge of the door.

Claims (3)

1. Automatic door with base lock type, consisting of a motor (6), a long threaded shaft (1) installed on both the left and right sides of the door, and a door base locking device (2) to move the door base up and down when the motor (6) rotates up and down. Its specific characteristic is that when the motor (6) starts rotating, it transmits power to the power transmission shaft (5), causing the power transmission shaft (5) to start rotating according to the driving force of the motor (6). The shaft of the power transmission shaft (5) has horizontal bevel gears (4) attached to both the left and right sides. And when the power transmission shaft (5) starts rotating, the horizontal bevel gear (4) will rotate accordingly, causing the vertical bevel gear (3) to rotate due to the gear teeth that mesh together. And at the gear shaft, the vertical bevel gear (3) is locked against the long threaded shaft (1). Therefore, when the vertical bevel gear (3) starts rotating, the long threaded shaft (1) will rotate as well. It causes the door base lock assembly (2), one end of which is locked to the door base (7), and the other end is connected to the long, continuous threaded shaft (1), so that when the long, continuous threaded shaft (1) starts to rotate, the door base lock assembly (2) will move up and down in the direction of the left or right rotation of the long, continuous threaded shaft (1), causing the door base (7) to move the door up and down as desired. 2. An automatic door opening and closing with a base locking mechanism according to claim 1, wherein a chain (31) is used to move the door edge up and down, comprising a motor (6), a motor power transmission chain (31), a power transmission chain moving the door base (11), and a door base lock assembly (2) to move the door base up and down when the motor (6) rotates up and down, characterized in that, when the motor (6) begins to rotate, power is transmitted to the motor power transmission chain (31), causing the power transmission chain moving the door base (11) to begin rotating in response to the force of the motor (6), where at the end of the motor power transmission chain (31) there is a coupling gear assembly (61) which connects the motor power transmission chain (31) and the door base power transmission chain (11), so that when the motor power transmission chain (31) rotates, it causes the power transmission chain moving the door base (11) to rotate in response, with one side of the power transmission chain The door base (11) has a door base lock assembly (2) connected to it and on the other side of the door base lock assembly (2) is locked to the door base (7), so when the power transmission chain moves the door base (11) up and down, it will cause the door base lock assembly (2) and the door base (7) to move up and down as desired. 3. An automatic door opening and closing with a locking base according to claim 1, wherein a wire rope (311) is used to move the door edge up and down, comprising a motor (6), a door base lock assembly (2), and an upper wire rope directional pulley (611) and a lower wire rope directional pulley (711), characterized by the fact that when the motor (411) starts to rotate to transmit power, the wire rope (311) wrapped around the shaft of the motor (6) moves to the left and right in the direction of rotation of the motor. When the motor (6) starts to rotate counterclockwise, the wire rope (311) starts to move to the left and the wire rope (311) passes through the upper wire rope directional pulley (611), causing the side wire rope (111) to move down, which the side wire rope (111) passes through the lower wire rope directional pulley (711), causing the outer and inner side wire ropes (111) to run in opposite directions. Therefore, when the outer side cable (111) runs down, the inner side cable (111) will run up. The inner side cable (111) has the door base lock assembly (2) attached to it, and the other side of the door base lock assembly (2) has the other side attached to the door base (7). Therefore, when the inner side cable (111) runs up, it will lift the door base lock assembly (2) and door base (7) up accordingly. And in the event that the motor (6) rotates clockwise, it will cause the inner side cable (111) to move down, which will cause the door base lock assembly (2) and door base (7) to move down accordingly as well.
