Description

Technical Field

[0001] This invention relates to the field of storage cabinet door structure technology, specifically to a sliding door structure suitable for intelligent storage cabinets that has sealing and locking functions. Background Technology

[0002] Currently, most existing smart lockers (such as parcel lockers, vending machines, and file storage cabinets) use structures like double doors, sliding doors, or roller shutters. These doors often rely solely on simple mechanical locks or magnetic closures, resulting in insufficient sealing and clamping force. This is especially problematic outdoors or in environments with large temperature differences, where inadequate sealing and the intrusion of dust or moisture can easily occur. Furthermore, existing sliding doors lack an effective clamping mechanism during closure, leading to gaps between the door and the cabinet body, affecting insulation, moisture resistance, and security. Therefore, it is necessary to provide a door structure that automatically achieves a tight seal when closed, thereby improving the overall performance and lifespan of the locker. Summary of the Invention

[0003] The present invention aims to solve the problems of poor sealing and loose closing of existing intelligent storage cabinet doors, and provides an automatic sealing door for storage in special gas environments that is simple in structure, reliable in operation, and can achieve automatic sealing and clamping.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic sealing door for storage in special gas environments, comprising: The door frame has an opening at the top; The first guide rail is arranged parallel to both sides of the opening. The first guide rail is provided with an upper guide groove and a lower guide groove respectively. The top of the upper guide groove and the lower guide groove are bent towards the door frame. A sliding door, slidably mounted on the first guide rail, has upper and lower guide wheels respectively located at its upper and lower ends on both sides. The upper guide wheel is movably mounted in the upper guide groove, and the lower guide wheel is movably mounted in the lower guide groove. A drive assembly that drives the sliding door to rise or fall. When the drive assembly drives the sliding door to rise to the top of the first guide rail, the upper guide wheel and the lower guide wheel move to the top of the upper guide groove and the lower guide groove respectively, thereby driving the sliding door to press against the door frame and achieve a sealing and locking.

[0005] Furthermore, the drive assembly includes a drive motor, a rotating shaft, a timing belt, a mounting base, and connecting components. The drive motor and the rotating shaft are fixed to the upper part of the door frame opening. The drive motor drives the rotating shaft to rotate in both directions. The two ends of the rotating shaft are respectively connected to the first end of the timing belt. The fixed base is located directly below the end of the rotating shaft and is connected to the second end of the timing belt. The first end of the connecting component is fixedly connected to the timing belt, and the second end of the connecting component is fixedly connected to the sliding door.

[0006] Furthermore, the connecting assembly includes a second guide rail, an upper movable seat, a lower movable seat, a fixing block, a guide rod, and a spring. The second guide rail is located outside the first guide rail. The upper movable seat and the lower movable seat are respectively located at the upper and lower ends of the second guide rail. The guide rods are respectively connected to the upper movable seat and the lower movable seat. The first end of the fixing block is sleeved on the guide rod, and the second end is fixedly connected to the timing belt. The spring is sleeved on the guide rod and located between the fixed block and the lower movable seat, serving to reduce shock.

[0007] Furthermore, connecting plates extend outward from the top of both sides of the sliding door, extending above the upper moving seat and the lower moving seat. The connecting plates are fixedly connected to the upper moving seat and the lower moving seat respectively by bolts, thereby realizing the detachable connection between the sliding door and the connecting assembly.

[0008] Furthermore, the first guide rail is in the shape of a right angle, its bottom is fixedly connected to the door frame, and its side wall is provided with the upper guide groove and the lower guide groove.

[0009] Furthermore, it also includes an upper contact switch and a lower contact switch. The upper contact switch is located above the door frame opening. When it detects that the sliding door has reached the top position, it controls the sliding door to stop moving. The lower contact switch is located below the door frame opening. When it detects that the sliding door has reached the bottom position, it controls the sliding door to stop moving.

[0010] Furthermore, the bending angles of the upper guide groove and the lower guide groove are 90° to 150° to ensure that the sliding door can be tightly pressed together when it rises to the top.

[0011] Furthermore, a sealing strip is provided at the edge where the sliding door contacts the door frame.

[0012] Furthermore, it also includes a controller that receives signals from the upper and lower contact switches and controls the start and stop of the drive motor.

[0013] The present invention has the following beneficial effects: 1. The present invention uses a bending design at the top of the guide groove to automatically achieve a tight seal when the sliding door is raised to the top. The structure is simple and reliable, and the sealing performance is good.

[0014] 2. It adopts synchronous belt and connecting components for drive, which ensures smooth transmission, low noise and long service life.

[0015] 3. A spring damping structure is set in the connecting components to reduce the impact during the movement of the sliding door and improve the stability of the system.

[0016] 4. Install upper and lower contact switches to achieve precise control of the sliding door position, thereby improving safety and automation.

The first guide rail 2 is right-angled, and its sidewalls have an upper guide groove 21 and a lower guide groove 22, both of which are bent inwards towards the door frame 1 at their tops. Upper guide wheels 31 and lower guide wheels 32 are installed on the upper and lower sides of the sliding door 3, respectively, and are embedded in the upper guide groove 21 and lower guide groove 22. A sealing strip is provided on the edge of the sliding door 3 that contacts the door frame 1.

[0023] The drive assembly 4 includes a drive motor 41, a rotating shaft 42, a timing belt 43, a fixed base 44, and a connecting assembly 45. The drive motor 41 drives the rotating shaft 42 to rotate, and the timing belt 43 pulls the connecting assembly 45, thereby causing the sliding door 3 to slide up and down along the first guide rail 2.

[0024] When the sliding door 3 rises to the top, the upper guide wheel 31 and the lower guide wheel 32 slide into the bent portion of the guide groove, forcing the sliding door 3 to move towards the door frame 1, thus achieving a tight seal. The bending angle of the bent portion is 90° to 150° to ensure that the sliding door 3 can be tightly pressed together when it rises to the top.

[0025] The door frame 1 is also equipped with an upper contact switch 11 and a lower contact switch 12 for detecting the position of the sliding door and controlling the motor to stop. Furthermore, it also includes a controller that receives signals from the upper contact switch 11 and the lower contact switch 12 and controls the start and stop of the drive motor 41.

[0026] The connecting assembly 45 includes a second guide rail 451, an upper movable seat 452, a lower movable seat 453, a fixing block 454, a guide rod 455, and a spring 456. The upper movable seat 452 and the lower movable seat 453 are fixedly connected by the guide rod 455 and slidably mounted on the second guide rail 451. The spring 456 is sleeved on the guide rod 455 to provide a buffering effect. Connecting plates 33 extend from the top of both sides of the sliding door 3 and are fixed to the connecting assembly 45 by bolts for easy disassembly and maintenance.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
