Description

A quick-opening and closing auxiliary device for a single-leaf airtight partition door in an area Technical Field

[0001] This utility model provides a rapid opening and closing auxiliary device, belonging to the technical field of single-leaf airtight partition doors for intervals, and particularly relates to a rapid opening and closing auxiliary device for single-leaf airtight partition doors for intervals. Background Technology

[0002] A single-leaf airtight partition door is a protective device installed within subway tunnels. Its primary purpose is to prevent the spread of shockwaves from nuclear and conventional weapon explosions, as well as various chemical agents, through the tunnel during wartime, protecting personnel and equipment. Existing single-leaf airtight partition doors typically consist of a door leaf, door frame, movable threshold, locking device, and hinges, using mechanical transmission to open and close the door leaf. However, existing devices have the following shortcomings: First, the opening and closing speed is slow, making it difficult to meet the demands of rapid response; second, the door leaf movement during opening and closing is limited, usually relying only on rotation or translation, resulting in unstable opening and closing actions that affect the sealing effect; third, operation is complex, requiring significant opening, closing, and locking forces, and problems such as jamming and abnormal noises can occur, impacting the user experience.

[0003] To address the shortcomings of existing technologies, this application provides a rapid opening and closing auxiliary device for a single-leaf airtight partition door. This device achieves rapid opening and closing of the sealed movable door through the coordinated action of a hydraulic telescopic device, a gear transmission mechanism, and a crank-slider structure. The hydraulic telescopic device serves as the power source, driving a drive gear to rotate via a gear plate. The drive gear simultaneously drives an L-shaped rotating plate and a transmission gear. The rotation of the L-shaped rotating plate causes the sealed movable door to rotate and open or close, while the transmission gear, through the crank-slider structure, drives a slider to slide along a rail, further assisting the sealed movable door in completing a translational movement. This dual motion of rotation and translation not only improves the speed of door opening and closing but also ensures the stability and sealing of the door during the opening and closing process. Furthermore, the device's design, combining hydraulic drive and gear transmission, avoids the complexity and noise problems of traditional mechanical transmissions, while enhancing the system's reliability and durability. Through this innovative structural design, this device can quickly respond to the opening and closing needs of the partition door, significantly improving the efficiency and safety of the partition door's use. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this application provides a rapid opening and closing auxiliary device for a single-leaf airtight partition door, which solves the problems of slow opening and closing speed, poor stability and insufficient sealing of the existing device, and achieves a fast, stable and reliable opening and closing effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick opening and closing auxiliary device for a single-leaf airtight partition door, including a wall, the interior of which is provided with a sealed movable door, and a drive gear is fixedly connected to one side of the sealed movable door via an L-shaped rotating plate that is movably connected, and gear plates and transmission gears that mesh with themselves are respectively provided on both sides of the drive gear.

[0006] One end of the gear plate is fixedly connected to a hydraulic telescopic device, which is fixedly installed in a slide rail located inside the wall. The slide rail is equipped with a slider that is movably connected to the sealed movable door.

[0007] A crank-slider structure is fixedly connected above the transmission gear and is also fixedly connected to the slider.

[0008] Preferably, the slider and the slide rail correspond, and the sealed movable door is provided with a movable rod that passes through itself and is inserted into the slider, so as to ensure that the sealed movable door adapts to the rotation of the rotating plate during the movement.

[0009] Preferably, the sealed movable door has a rectangular fitting groove on the side near the rotating plate, the fitting groove corresponds to the rotating plate, one end of the rotating plate is movably connected to the midpoint of the fitting groove, and the other end is fixedly connected to the drive gear.

[0010] Preferably, a support rod is fixedly connected below both the drive gear and the transmission gear, and the support rod is movably located inside the wall.

[0011] Preferably, the crank-slider structure includes a driving rod fixedly connected to a transmission gear, a driven rod movably connected to the other end of the driving rod, and a driven rod movably connected to the other end of the driven rod, which pulls the slider to move horizontally in the slide rail.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This invention utilizes a hydraulic telescopic device for activation, which moves a gear plate along the meshing direction with a drive gear, causing the drive gear to rotate. Simultaneously, the rotation of the drive gear drives the rotation of a transmission gear meshing with it on the other side. The crank-slider structure above the transmission gear operates accordingly, with the crank driving the slider to slide along a slide rail. The sliding of the slider, in turn, causes the movably connected sealing door to slide along one side of the wall. At the same time, the rotation of the drive gear also drives the L-shaped rotating plate fixedly connected to it to rotate, further assisting the sealing door in its rotational action. Under the combined effects of rotation and sliding, the sealing door quickly moves to one side of the wall, completing the opening action. When it is necessary to close the sealing door, the hydraulic telescopic device reverses its action, causing the gear plate to move in the opposite direction. The drive gear and transmission gear then rotate in the opposite direction, and the crank-slider structure causes the slider to slide in the opposite direction along the slide rail. The sealing door, under the combined effects of reverse rotation and sliding, returns to its original position, tightly fitting against the wall to achieve its sealing function. Throughout the entire process, all components work together to ensure the rapid and smooth opening and closing of the sealing door.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] As shown in Figures 1 and 2, a rapid opening and closing auxiliary device for a single-leaf airtight partition door is disclosed. This device achieves rapid opening and closing of the sealed movable door through the coordinated action of a hydraulic telescopic device, a gear transmission mechanism, and a crank-slider structure. The device includes a wall 1, inside which a sealed movable door 2 is installed. The sealed movable door 2 is connected to a drive gear 4 via an L-shaped rotating plate 3. The drive gear 4 meshes with a gear plate 5 and a transmission gear 6 on both sides, respectively. The gear plate 5 is connected to a hydraulic telescopic device 7, which is fixed to a slide rail 8 within the wall 1. A slider 9 connected to the sealed movable door 2 is located within the slide rail 8. A crank-slider structure 10 is connected above the transmission gear 6, enabling the sealed movable door 2 to translate via the slider 9. This device, through the combination of hydraulic drive and gear transmission, ensures that the door can both rotate and translate during opening and closing, meeting the rapid opening and closing requirements of the partition door.

[0026] In this embodiment, the hydraulic telescopic device 7 serves as the core power source, driving the drive gear 4 to rotate via the gear plate 5. The drive gear 4 simultaneously drives the L-shaped rotating plate 3 and the transmission gear 6. The rotation of the L-shaped rotating plate 3 enables the sealed movable door 2 to open or close, while the transmission gear 6, through the crank-slider structure 10, drives the slider 9 to slide along the slide rail 8, further assisting the sealed movable door 2 in completing the translational movement. This dual motion of rotation and translation not only improves the speed of door opening and closing but also ensures the stability and sealing of the door during the opening and closing process. Furthermore, the device employs a design combining hydraulic drive and gear transmission, avoiding the complexity and noise problems of traditional mechanical transmission while enhancing the system's reliability and durability. Through this innovative structural design, this device can quickly respond to the opening and closing needs of the partition door, significantly improving the efficiency and safety of the partition door.

[0027] As shown in Figures 3 and 4, the detailed design of the device ensures the stability and sealing of the opening and closing action. The slider 9 cooperates with the slide rail 8, and the sealed movable door 2 is connected to the slider 9 via the movable rod 11, adapting to the rotation of the rotating plate 3. The sealed movable door 2 has a fitting groove 12 on the side near the rotating plate 3, and the rotating plate 3 is movably connected to the midpoint of the fitting groove 12, with the other end fixed to the drive gear 4. A support rod 13 is provided below the drive gear 4 and the transmission gear 6 to enhance structural stability. The crank-slider structure 10 consists of a driving rod and a driven rod. The driving rod is fixed to the transmission gear 6, and the driven rod is movably connected to the slider 9, enabling the translation of the slider 9. When the hydraulic telescopic device 7 is activated, the gear plate 5 drives the drive gear 4 to rotate, and simultaneously, the transmission gear 6 drives the slider 9 to move along the slide rail 8 via the crank-slider structure 10, completing the rapid opening and closing action of the sealed movable door 2.

[0028] The innovation of this implementation plan is mainly reflected in the following aspects:

[0029] 1. The combination of the hydraulic telescopic device 7 and the gear transmission mechanism enables the rapid opening and closing of the sealed movable door 2, improving the opening and closing speed and efficiency.

[0030] 2. The coordinated action of the gear transmission mechanism and the crank-slider structure 10 enables the sealed movable door 2 to both rotate and translate during the opening and closing process, ensuring the stability and sealing of the opening and closing action.

[0031] 3. The hydraulic telescopic device 7 uses a small-stroke hydraulic cylinder to drive the X-type telescopic mechanism, which can achieve a telescopic range much greater than the stroke of the hydraulic cylinder. The structure is stable and easy to maintain.

[0032] Key implementation points include:

[0033] 1. The model selection of the hydraulic telescopic device 7 should be determined according to actual needs. For example, a certain model of hydraulic cylinder can be selected, with a maximum stroke of 300mm and a maximum thrust of 10kN, to meet the technical parameter requirements of opening and closing force not exceeding 150N and locking operation force not exceeding 250N.

[0034] 2. In the gear transmission mechanism, the module of the drive gear 4 and the transmission gear 6 can be designed to be 2mm, with 20 and 30 teeth respectively, to ensure a reasonable transmission ratio and achieve smooth transmission.

[0035] 3. In the crank-slider structure 10, the lengths of the driving rod and the driven rod can be designed according to the actual space and motion requirements. For example, the length of the driving rod is 150mm and the length of the driven rod is 200mm, so that the translation distance of the slider 9 meets the opening and closing requirements of the sealed movable door 2.

[0036] 4. In the specific implementation process, the installation example of a protective airtight partition door in a subway section can be referred to. The door opening and closing force is no more than 150N, the locking operation force is no more than 250N, and there is no jamming or abnormal noise when opening, closing and locking, which meets the main technical parameters and performance indicators.

[0037] In operation, firstly, the hydraulic telescopic device 7 is activated. The hydraulic telescopic device 7 pushes the gear plate 5 to move along the meshing direction with the drive gear 4, causing the drive gear 4 to rotate. Simultaneously, the rotation of the drive gear 4 drives the transmission gear 6, which meshes with it on the other side, to rotate. The crank-slider structure 10 above the transmission gear 6 operates accordingly, with the crank driving the slider 9 to slide along the slide rail 8. The sliding of the slider 9 further drives the movably connected sealing door 2 to slide along one side of the wall 1. At the same time, the rotation of the drive gear 4 also drives the L-shaped rotating plate 3, which is fixedly connected to it, to rotate. The rotation of the L-shaped rotating plate 3 further assists the sealing door 2 in achieving its rotational action. Under the combined action of rotation and sliding, the sealing door 2 quickly moves to one side of the wall 1, completing the opening action. When it is necessary to close the sealing door 2, the hydraulic telescopic device 7 reverses its action, causing the gear plate 5 to move in the opposite direction. The drive gear 4 and transmission gear 6 then rotate in the opposite direction. The crank-slider structure 10 drives the slider 9 to slide in the opposite direction along the slide rail 8. Under the action of reverse rotation and sliding, the sealing door 2 resets, tightly fitting against the wall 1, achieving the sealing function. Throughout the process, all components work together to ensure the rapid and smooth opening and closing of the sealed movable door 2.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
