A self-pressurizing lifting door at the end face

Abstract

This utility model provides a self-clamping lifting door, characterized by including a lifting structure and a closing structure. The closing structure is provided on one side of the lifting structure, and the lifting structure and the closing structure are connected by welding. This utility model improves the closing structure, which is composed of connecting parts, fixing bolts, springs, a plate, a door panel, and a cabin. The closing structure can achieve the clamping and sealing of the cabin and the door panel through fixing bolts and springs, replacing the existing technology that uses a cylinder to provide clamping force, reducing procurement costs. The bolt and spring structure is simple, and only periodic checks are needed to check whether the bolts are loose and whether the springs have lost their elasticity, significantly reducing maintenance costs. Once the bolts and springs are installed and adjusted, as long as their materials and specifications are selected appropriately, they can provide stable clamping force, unaffected by external factors such as air sources, and can be used in high-temperature and high-pressure environments, reducing the occurrence of failure points.

Description

Technical Field

[0001] This utility model relates to the field of lifting door technology, and in particular to a lifting door with self-pressurizing end face. Background Technology

[0002] Currently, material transfer between glove boxes and other compartments is usually achieved through internal revolving doors. However, these revolving doors require manual operation with gloves, which is inconvenient and poses safety hazards. Furthermore, ensuring the stability of the environment inside the glove box is crucial for some experimental or production processes with strict environmental requirements.

[0003] Existing patent CN212385513U provides an automatic lifting and sealing door, comprising: a cylinder assembly, a door panel assembly, a first valve plate, and a second valve plate; the first valve plate and the second valve plate are arranged opposite to each other, and each has a first through hole positioned opposite to the other at its lower part; the door panel assembly is located between the first valve plate and the second valve plate; the cylinder assembly is connected to the door panel assembly and is used to drive the door panel assembly to move downward or upward, so that the door panel assembly completely covers or exposes the first through hole. In this invention, by controlling the lifting and lowering movement of the door panel assembly through the cylinder assembly, the automatic opening and closing of the sealing door can be achieved, solving the problem that the revolving door on the glove box in the prior art requires manual operation with gloves, which is inconvenient.

[0004] Problems identified in existing technologies: The cylinder itself and its supporting air circuit system, such as air source processing components, air pipes, valves, etc., have high overall procurement costs in existing technologies; the cylinder system in existing technologies is relatively complex, requiring regular checks for air circuit leaks and cylinder piston wear, etc., making maintenance cumbersome and costly; the operation of the cylinder in existing technologies depends on a stable air source and control system. If the air source fails or the air pressure is unstable, it may lead to insufficient or unstable clamping force, affecting the sealing effect of the door. Utility Model Content

[0005] In view of the above technical problems, the present invention provides a self-pressurizing lifting door, characterized in that it includes a lifting structure and a sealing structure, wherein a sealing structure is provided on one side of the lifting structure, and the lifting structure and the sealing structure are connected by welding.

[0006] The lifting structure consists of a fixed base and a rodless cylinder. The rodless cylinder is provided on one side of the fixed base, and the fixed base and the rodless cylinder are connected by a threaded nut.

[0007] The enclosed structure comprises a connector, fixing bolts, springs, a plate, a door panel, and a cabin. A plate is located on one side of the connector, and the connector and plate are movably connected by fixing bolts. Springs are fitted onto the fixing bolts. A door panel is located on one side of the plate, and the plate and door panel are connected by welding. A cabin is located below the door panel, and the door panel is movably connected to the cabin. A hole is formed on one side of the connector, and the connector is connected to the lifting structure by threads and nuts. The bottom of the door panel is wedge-shaped. A groove is formed on one side of the cabin, and the groove is the same wedge shape as the bottom of the door panel.

[0008] The beneficial effects of this utility model are as follows:

[0009] This utility model improves the closed structure, which consists of connectors, fixing bolts, springs, a plate, a door panel, and a cabin. The closed structure can achieve the tight sealing of the cabin and the door panel through fixing bolts and springs, replacing the existing technology that uses a cylinder to provide clamping force. This reduces procurement costs. The bolt and spring structure is simple, and only periodic checks are needed to check whether the bolts are loose and whether the springs have lost their elasticity. Maintenance costs are greatly reduced. Once the bolts and springs are installed and adjusted, as long as their materials and specifications are selected appropriately, they can provide stable clamping force, unaffected by external factors such as air sources. This allows it to be used in high-temperature and high-pressure applications, reducing the occurrence of failure points. Attached Figure Description

[0015] Example 1

[0016] This utility model provides a self-closing lifting door with an end face, characterized in that the lifting structure consists of a fixed base 15 and a rodless cylinder 16, and the sealing structure consists of a connector 10, fixing bolts 11, a spring 9, a plate 8, a door panel 7, and a cabin 6.

[0017] A rodless cylinder 16 is provided on one side of the fixed base 15. The fixed base 15 and the rodless cylinder 16 are connected by a threaded nut. A plate 8 is provided on one side of the connecting part 10. The connecting part 10 and the plate 8 are movably connected by a fixing bolt 11. A spring 9 is sleeved on the fixing bolt 11. A door panel 7 is provided on one side of the plate 8. The plate 8 and the door panel 7 are connected by welding. A cabin 6 is provided below the door panel 7. The door panel 7 and the cabin 6 are movably connected.

[0018] Example 2

[0019] When using this utility model, first install the fixing seat 15 and the cavity on the glove box. When the door needs to be opened, the rodless cylinder 16 drives the door panel 7 upward through the connector 10 and the plate 8. The door panel 7 disengages from the groove on one side of the cabin 6. At this time, the spring 9 unfolds during the cylinder's ascent. The spring 9 between the connector 10 and the fixing bolt 11 pushes the door panel 7 outward. After the door panel 7 is fully raised, the door opening action is completed. When the door needs to be closed, the rodless cylinder 16 drives the door panel 7 downward through the connector 10 and the plate 8. The door panel 7 enters the groove on one side of the cabin 6. At this time, the spring 9 is compressed during the cylinder's ascent. The spring 9 between the connector 10 and the fixing bolt 11 presses the door panel 7 inward. The spring 9 provides the power to create distance between the two sealing surfaces of the door panel 7 and the cabin 6. After the gap between the door panel 7 and the cavity is completely closed, the door closing action is completed.

The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
