Description

Quick door structure

Technical Field

The utility model relates to the technical field of rolling doors,

more particularly, the present invention relates to a quick door structure.

Background

The rolling door is a door which is connected in series by a plurality of movable door sheets, can be contracted and extended by rotating up and down in a fixed slideway by taking a scroll above the door as a center, and is widely applied to the society by a simple structure and low cost. At present, because the rolling door and the track are in sliding contact in use, the resistance received when the rolling door is rolled is large, the rolling speed is reduced, and meanwhile, the rolling door and the track are abraded due to mutual friction, so that the service life is shortened. The fast coiling device for the hard roller shutter door as introduced in the Chinese patent CN211598455U comprises a shell, wherein supports are bolted at the left side and the right side of the bottom of the shell, a coiling device is installed below the inside of the shell, a roller shutter door body matched with the coiling device is installed below the coiling device, notches are arranged on the surface of one side, opposite to the supports, of each support, a track groove is formed in each support, a plurality of connecting rods are bolted at the left side and the right side of the roller shutter door body, one ends, far away from the roller shutter door body, of the connecting rods extend to the inside of the track groove and are bolted with a sliding block, a first pulley is bolted at one side, far away from the connecting rods, of each sliding block, vertical tracks are bolted at the positions, close to the notches, at the front side and the rear side of the inside of the track groove, a plurality of second pulleys are rotatably connected to the inner wall of each vertical track, and the surface of one side, opposite to the second pulleys, is respectively connected with the front surface and the rear surface of each sliding block in a rolling manner, the inner wall of the track groove, which is far away from one side of the connecting rod, is provided with a vertical sliding groove, the first pulley is in rolling connection with the inner wall of the vertical sliding groove, and a power mechanism and a driving mechanism are respectively arranged inside the shell; the utility model discloses a can reduce the frictional force between rolling door and the track, promote the rolling speed, promote and batch efficiency, can reduce wearing and tearing between rolling door and the track simultaneously, increase the life of rolling door, solved present stereoplasm rolling door in use, because be sliding contact between its rolling door and the track, the resistance that receives when leading to its rolling is bigger, the rolling speed descends, friction each other makes rolling door and track receive wearing and tearing simultaneously, reduce life's problem.

However, the inner wall of the vertical track introduced in the scheme is rotatably connected with a plurality of second pulleys, the surfaces of the opposite sides of the second pulleys are respectively in rolling connection with the front surface and the rear surface of the sliding block, the inner wall of the track groove and the inner wall of the side far away from the connecting rod are provided with vertical sliding grooves, the first pulleys are in rolling connection with the inner walls of the vertical sliding grooves, namely, the sliding blocks at the end parts of the rolling door slide on the pulleys between the tracks to reduce friction force, which means that the tracks need very dense pulleys to ensure the working stability, so that the number of the pulleys is large, and each pulley must be ensured to be on the same straight line, thereby bringing inconvenience to manufacture and installation and being difficult to maintain; when the slider passes from one pulley to another pulley, the slider constantly leaves a pulley to with another pulley contact, can produce little collision, once open the door or close the door, every slider can carry out once contact collision with a plurality of pulleys, and is more serious to the friction of slider and pulley, and can produce the noise.
