Abstract
Description
Technical Field
[0001] The utility model relates to a retractable upward-opening door mechanism, belonging to the technical field of upward-opening door mechanisms. Background Art
[0002] Upward-opening doors are relatively common in some equipment in production, processing and real life. However, in the prior art, the door body of the upward-opening door mostly uses a gas spring strut device for supporting the door body. This method occupies a relatively large space and is not suitable for narrow environments such as underground mines.
[0003] Therefore, there is an urgent need for a retractable upward-opening door mechanism that can complete the storage of the upward-opening door, reduce the space occupied by the upward-opening door, and make it applicable to narrow environments such as underground roadways. Summary of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a retractable upward-opening door mechanism. The upward-opening door mechanism completes the storage of the upward-opening door panel through the cooperation among a hook, a bearing and a track, greatly reducing the space occupied by the upward-opening door and making it applicable to narrow environments such as underground roadways.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] A retractable upward-opening door mechanism includes a door panel, a bearing and a track. Hooks are fixedly connected to both sides of the door panel. An installation hole is provided at one end of the track close to the door panel. A shoulder screw is connected in the installation hole. The bearing is installed in the installation hole of the track through the shoulder screw and an elastic gasket. The cross section of the hook is arc-shaped, and the hook covers the outer circumference of part of the bearing.
[0007] In an embodiment of the utility model, the hook is installed on the door panel through a fastening screw.
[0008] In an embodiment of the utility model, limiting plates are provided on both sides of the hook. The limiting plates are fixedly connected to the door panel, and the bearing is located between the two limiting plates.
[0009] In an embodiment of the utility model, the shoulder screw is located on the side of the limiting plate away from the door panel.
[0010] In an embodiment of the utility model, a washer is also installed between the bearing and the track through a shoulder screw.
[0011] In an embodiment of the utility model, the bearing is a plastic bearing.
[0012] In an embodiment of the utility model, the door panel is of a plate-shaped structure.
[0013] In an embodiment of the present utility model, the track is a rod-shaped structure.
[0014] The retractable upward-opening door mechanism provided by the present utility model has the following beneficial effects:
[0015] 1. For the retractable upward-opening door mechanism provided by the present utility model, its bearing is installed in the corresponding mounting hole of the track through a shoulder screw and an elastic gasket. When installing the bearing, the washer is installed between the bearing and the track through the shoulder screw to prevent friction between the bearing and the track when the bearing rolls. During use, after the door panel is opened, it can be rotated through the hook. After the door panel rotates 90°, the door panel is pushed forward, and the door panel slides along the track to complete the storage. This upward-opening door mechanism completes the storage of the upward-opening door panel through the cooperation among the hook, the bearing, and the track, greatly reducing the space occupied by the upward-opening door, and enabling it to be used in narrow environments such as underground roadways.
[0016] 2. For the retractable upward-opening door mechanism provided by the present utility model, the limiting plates on both sides of the bearing are used to limit both sides of the bearing, avoiding the offset and detachment of the bearing caused by the insecure fixation of the shoulder screw. Among them, the cross-section of the hook is arc-shaped, which can cover most of the outer periphery of the hook, so that the bearing can be stuck in the arc-shaped hook. When the bearing moves towards the door panel, the limiting plate plays a limiting role on the shoulder screw, avoiding further movement of the shoulder screw and the bearing towards the door panel, thereby preventing the bearing from detaching from the notch of the hook.
[0017] 3. For the retractable upward-opening door mechanism provided by the present utility model, the structural design in which the hook covers the outer periphery of part of the bearing facilitates the disassembly and assembly of the upward-opening door mechanism. When the shoulder screw is removed, without the limiting effect of the limiting plate on the shoulder screw, the bearing can move a certain distance further towards the door panel, enabling the bearing to pass through the notch of the hook, facilitating the disassembly and installation of the bearing, and increasing the convenience of use and maintenance of the flap door mechanism.
[0018] 4. For the retractable upward-opening door mechanism provided by the present utility model, when installing the bearing, the washer is installed between the bearing and the track through the shoulder screw to prevent friction between the bearing and the track when the bearing rolls.
