Description

Technical Field

[0001] This invention relates to the field of hatch sealing technology, specifically to a vertically pressing push-pull sealing door. Background Technology

[0002] The design of the sealing structure is a crucial part of pressure vessels and oxygen chambers. Common sealing methods include forced sealing and self-tightening sealing. Forced sealing structures, such as flange connections, are typically used in low and medium pressure vessels. These rely on tightening bolts to generate a pre-tightening force on the gaskets, achieving an initial seal. As pressure increases, the gaskets generate sufficient rebound force to maintain a seal under operating conditions. Self-tightening seals are commonly used in high-pressure vessels, but under high-pressure conditions, this leads to a shorter lifespan for the seals and unreliable sealing performance. With the increasing size of pressure vessels and the diversification of their applications, uneven sealing gaps between the door panels and frames can occur due to machining errors and assembly precision issues, resulting in poor sealing.

[0003] To minimize the space occupied by the door when open, existing sliding doors on the market, using the existing sliding door structure, have the following main problems during use: First, they lack a sealing function, only having an opening and closing function; when closed, gaps of varying sizes exist between the door panel and the door frame. Second, the sliding door has a downward sliding track, which causes great inconvenience and safety hazards for people walking and transporting goods, especially as the pressure vessel of a medical air pressurization oxygen chamber. Due to the existence of the downward sliding track, it is extremely inconvenient for the elderly, weak, sick, disabled, and stretcher vehicles to enter and exit, and the safety hazards are extremely high. Third, when the sliding door is closed, it still needs to be manually or by other locking methods to achieve a seal, which results in poor sealing effect and consumes manpower.

[0004] Sealed doors, designed to prevent the leakage of gases, liquids, or solid particles from one area to another, are widely used in numerous fields such as industrial equipment, medical equipment, and food processing, including cleanrooms, medical oxygen chambers, and food processing rooms. Sliding sealed doors, on the other hand, are designed with a sliding opening mechanism. To ensure the door's airtightness, traditional sliding sealed doors often have the sealing strip and sealing surface designed very close together, even overlapping. This causes the door body and sealing strip to easily scrape against each other during opening and closing, resulting in the following problems: firstly, the sealing strip wears, deforms, or even falls off; secondly, excessive resistance during opening and closing can easily cause jamming, leading to noise problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the problems existing in the background art, thereby providing a sealing door structure with good sealing performance, reliable operation and convenient operation, specifically a vertical pressing type push-pull sealing door.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a vertically pressing push-pull sealing door, including a door body and a door frame, and further including a door opening and closing mechanism and a sealing assembly. The door opening and closing mechanism is provided in two sets, which are respectively installed on the upper and lower sides of the door frame. The door body is connected to the door frame through the two sets of vertically arranged door opening and closing mechanisms. The door opening and closing mechanism includes a mounting plate, a slide rail assembly, a follower shaft, a connecting rod, a bearing, a door hinge, and a locking mechanism. Multiple sets of bearings are provided. The mounting plate is disposed on the door frame, and the slide rail assembly is disposed on... The mounting plate has mounting holes corresponding to the door hinges on the upper and lower sides of the door body. The follower shaft is mounted in the mounting plate via bearings and connected to the slide rail assembly. One end of the connecting rod is mounted on the slide rail assembly, and the other end is connected to the door hinge mounted on the door body. One end of the door hinge is mounted in the mounting plate via bearings, and the other end is connected to the door hinge via the mounting holes on the door body. The locking mechanism is mounted on the follower shaft to limit the rotation direction of the follower shaft. The sealing assembly is mounted on the door frame to seal the door body when it is closed.

[0007] Furthermore, in the vertical pressing type push-pull sealing door of the present invention, the slide rail assembly includes a slide rail, a slider and a mounting base. The slide rail is disposed on the mounting plate, and the slider is installed in the slide rail. The slider can move linearly on the slide rail. The mounting base is fixedly installed on the slider. One end of the follower shaft is connected to the mounting base, and the other end is disposed in the mounting plate through a bearing.

[0008] Furthermore, in the vertically pressing push-pull sealing door of the present invention, the slide rail on the mounting plate includes a first slide rail and a second slide rail, the length of the first slide rail is greater than the length of the second slide rail, and the first slide rail and the second slide rail form an L-shaped structure.

[0009] Furthermore, in the vertical pressing type push-pull sealing door of the present invention, the locking mechanism includes a locking plate, a return torsion spring, and a mounting shaft. The locking plate is mounted on the follower shaft via the mounting shaft, and the return torsion spring is installed between the locking plate and the mounting shaft. The locking plate can rotate around the mounting shaft and has a top pressing notch in the locking plate. When the door is closed, the return torsion spring located between the locking plate and the mounting shaft, under the action of the spring force, causes the top pressing notch on the locking plate to lock onto the follower shaft, restricting the rotation of the follower shaft.

[0010] Furthermore, in the vertical pressing type push-pull sealing door of the present invention, the sealing assembly includes a sealing strip and a pressure plate. The sealing strip is bonded to the door frame with quick-drying adhesive. The other side of the sealing strip can be tightly attached to the door body. Screw holes are also provided on the door frame. The pressure plate is screwed into the screw holes through the sealing strip to fix the sealing strip on the door frame.

[0011] Furthermore, in the vertical pressing type push-pull sealing door of the present invention, the connecting rod is provided in two sets, and the two sets of connecting rods are symmetrically distributed on the upper and lower sides of the mounting plate. One end of each set of connecting rods is fixedly connected to the mounting seat in the slide rail assembly, and the other end is connected to the follower shaft. The follower shaft, which is fixedly connected to the mounting seat in the slide rail assembly, is rotatably connected to the connecting rod and the mounting plate respectively through bearings.

[0012] Furthermore, in the vertical pressing type push-pull sealing door of the present invention, the bearing is provided in six sets, and the six sets of bearings are respectively installed between the follower shaft and the connecting rod, between the connecting rod and the door hinge, between the follower shaft and the mounting plate, and at the connection between the door hinge and the mounting plate.

[0013] Furthermore, in the vertically pressing push-pull sealing door described in this invention, the door hinge is fixedly connected to the door body through mounting holes on the door body.

[0014] Furthermore, in the vertically pressing push-pull sealing door described in this invention, the two sets of door opening and closing mechanisms are installed in a staggered state on the upper and lower sides of the door frame, and the door body is connected to the door frame through the two sets of door opening and closing mechanisms.

[0015] Compared with the prior art, the vertical pressing type push-pull sealing door of the present invention has the following advantages: The door body and door frame are connected through the configured opening and closing mechanism. Because the slide rail on the mounting plate is L-shaped, the cooperation between the L-shaped slide rail and the locking plate to press against the follower shaft ensures good sealing performance between the door body and the door frame. Simultaneously, the two slide rails arranged vertically and vertically, along with multiple sets of bearings, not only ensure smooth opening and closing of the door but also reduce noise and resistance during opening and closing. Furthermore, the configured sealing components ensure that the door body and the sealing strip are only pressed together in the normal direction, preventing wear and deformation of the sealing strip and effectively avoiding scratching problems.

[0016] Therefore, the push-pull sealing door described in this invention, through the configured opening and closing mechanism and the cooperation of the slide rail assembly and the locking mechanism, can not only enable the door to move on the door frame, but also prevent jamming during the movement. Furthermore, the sealing component can improve its sealing performance. Its overall structure is compact, occupies little space, and is reasonably designed, making it suitable for widespread application. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] It should be noted that the term "comprising" or any other variation is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Example 1

[0024] like Figures 1 to 8 As shown, this embodiment provides a vertically pressing push-pull sealing door, including a door body 1, a door frame 2, a sealing assembly, and a door opening and closing mechanism. One side of the sealing assembly is fastened to the door frame, and the other side of the sealing structure is tightly attached to the door body. Two sets of door opening and closing mechanisms are provided, respectively installed on the upper and lower sides of the door frame 2. The door body 1 is connected to the door frame 2 through the two sets of vertically arranged door opening and closing mechanisms. The door opening and closing mechanism includes a mounting plate 3, a slide rail assembly, a follower shaft 7, a connecting rod 8, a bearing 9, a door hinge 10, and a locking mechanism. The mounting plate 3 is fastened to the door frame 2, and the mounting plate 3 is designed with an L-shaped movement track. The slide rail assembly includes a slide rail 4, a slider 5, and a mounting base 6. The slide rail... 4. The slider 5 is mounted on the slide rail 4 and the mounting seat 6 is mounted on the slider 5 in the motion track on the mounting plate 3; one end of the follower shaft 7 is connected to the mounting seat 6; one end of the connecting rod 8 is mounted on the follower shaft 7; the middle of the follower shaft 7 is located in the motion track on the mounting plate 3; one end of the door hinge 10 is connected to the connecting rod 8 and the other end of the door hinge 10 is connected to the door body 1; the middle of the door hinge 10 is located in the motion track in the mounting plate 3; the locking mechanism includes a locking plate 11, a return torsion spring 12 and a mounting shaft 13; the locking plate 11 is mounted on the follower shaft 7 through the mounting shaft; the return torsion spring 12 is installed between the locking plate 11 and the mounting shaft 13; the locking plate 11 presses against the follower shaft 7 when the door body 1 is closed.

[0025] In the specific manufacturing process, the push-pull sealing door provided in this embodiment is adopted. The door body 1 has good rigidity and strength and is not easy to deform. Mounting holes corresponding to the door hinge 10 are provided on the upper and lower sides of the door body 1.

[0026] The door frame 2 has good rigidity and strength and is not easily deformed. The door frame 2 is provided with threaded holes at the top and bottom for installing the mounting plate 3. At the same time, the door frame 2 is provided with threaded holes on the front for installing the sealing component.

[0027] like Figure 7 As shown, the sealing assembly includes a sealing strip 14 and a pressure plate 15. The sealing strip 14 is bonded to the door frame 2 with quick-drying adhesive, and the pressure plate 15 and the sealing strip 14 are firmly installed on the door frame 2 with screws to prevent the sealing strip 14 from falling off due to unstable quick-drying adhesive bonding. The mounting plate 3 in the door opening and closing mechanism is mounted on the door frame 2 by screws, and the slide rail assembly is mounted on the mounting plate 3 by screws, as shown below. Figure 4 As shown, the slide rail assembly includes a slide rail 4, a slider 5, and a mounting base 6. The slide rail 4 is mounted on the mounting plate 3, and the slider 5 is mounted on the slide rail 4, allowing the slider 5 to move linearly along the slide rail 4. The mounting base 6 is fixedly mounted on the slider 5. The follower shaft 7 is fixedly connected to the mounting base 6; the right side of the connecting rod 8 is fixedly connected to the mounting base 6, while the left side is connected to the follower shaft 7.

[0028] like Figure 6 As shown, the locking mechanism includes a locking plate 11, a return torsion spring 12, and a mounting shaft 13. The locking plate 11 is mounted on the follower shaft 7 via the mounting shaft 13, while the return torsion spring 12 is installed between the locking plate 11 and the mounting shaft 13. The locking plate 11 can rotate around the mounting shaft 13, and a pressing notch is provided in the locking plate 11. When the door 1 is closed, since the return torsion spring 12 is installed between the locking plate 11 and the mounting shaft 13, the spring force of the return torsion spring 12 can cause the pressing notch on the locking plate 11 to be stuck on the follower shaft 7, thereby preventing the follower shaft 7 from continuing to rotate.

[0029] Furthermore, in the vertically pressing push-pull sealing door provided in this embodiment, the two sets of door opening and closing mechanisms are installed in a staggered state on the upper and lower sides of the door frame 2. The door body 1 is connected to the door frame 2 through the two sets of door opening and closing mechanisms in a staggered state, which can improve the overall stability of the door body 1 during movement. At the same time, in order to ensure the accuracy of the position of the mounting plate 3 and the door frame 2, as well as the accuracy of the position of the door hinge 10 and the door body 1, the mounting holes on the door body 1 are designed as elongated oval holes, and the door hinge 10 is fixedly connected to the door body 1 through the mounting holes on the door body 1. Example 2

[0030] This embodiment is based on Embodiment 1. To ensure the stability of the door opening and closing mechanism, and to guarantee good performance between the follower shaft 7 and the connecting rod 8, between the follower shaft 7 and the mounting plate 3, and between the door hinge 10 and the mounting plate 3, as follows... Figure 5 As shown in this embodiment, a vertically pressing push-pull sealing door is adopted. Two sets of connecting rods 8 are provided, symmetrically distributed on the upper and lower sides of the mounting plate 3. One end of each connecting rod 8 is fixedly connected to the mounting seat 6 in the slide rail assembly, while the other end is connected to the follower shaft 7. The follower shaft 7, fixedly connected to the mounting seat 6 in the slide rail assembly, is rotatably connected to both the connecting rod 8 and the mounting plate 3 via bearings 9. Six sets of bearings 9 are provided, respectively installed between the follower shaft 7 and the connecting rod 8, between the connecting rod 8 and the door hinge 10, between the follower shaft 7 and the mounting plate 3, and at the connection points between the door hinge 10 and the mounting plate 3.

[0031] The opening process of the vertically pressing sliding sealing door described in this invention is as follows: like Figure 3 and Figure 4 As shown, when the door is opened, pushing the door body 1 to the left causes the bearing 9 to engage in the "L"-shaped track 4 within the mounting plate 3. Due to the action of the track 4, as the bearing 9 moves along the normal direction of the door body 1, it drives the door body 1, causing the door hinge 10 to move along the normal direction of the door body 1. Figure 2 As shown, under the action of the door hinge 10, the follower shaft 7 overcomes the action of the return torsion spring 12 and pushes the lock plate 11 to rotate counterclockwise. The follower shaft 7 loses its limit and moves to the left. At the same time, the door body 1 separates along the door frame 2, and the door body 1 and the sealing strip 14 are completely separated. As the follower shaft 7 continues to move, it drives the door hinge 10 to move to the left, and then drives the door body 1 to open to the left, completing the door opening action.

[0032] The closing process is as follows: like Figure 3 and Figure 4 As shown, when the door 1 is pushed to the right, the gap between the door 1 and the sealing strip 14 is relatively large. As it continues to move to the right, the bearing 9 moves to the rightmost end of the "L"-shaped track 4 in the mounting plate 3 and can no longer move to the right. Under the action of the pushing force, the sealing strip 14 is pressed tightly along the normal direction of the door 1. As it continues to press, the follower shaft 7 pushes open the lock plate 11 and continues to press. The follower shaft 7 passes over the lock plate 11. Under the action of the return torsion spring 12, the lock plate 11 returns to the limit position of the top pressing notch, blocking the follower shaft 7 and preventing it from moving to the left. At this time, the door 1 has pressed the sealing strip 14 tightly, and the closing process is completed.

[0033] Therefore, the push-pull sealing door described in this invention connects the door body 1 and the door frame 2 through the configured opening and closing mechanism. Since the slide rail 4 on the mounting plate 3 is set in an L-shaped structure, the cooperation between the L-shaped slide rail 4 and the locking plate 11 presses against the follower shaft 7, resulting in good sealing performance between the door body 1 and the door frame 2. At the same time, the two slide rails arranged vertically and the multiple sets of bearings not only ensure the smooth opening and closing of the door body 1, but also reduce the noise and resistance of opening and closing the door. In addition, the configured sealing components ensure that the door body 1 and the sealing strip 14 are only pressed in the normal direction, preventing the sealing strip 14 from wearing and deforming, and effectively avoiding the problem of scratching.

[0034] In summary, the push-pull sealing door described in this invention, through the configured opening and closing mechanism and the cooperation of the slide rail assembly and the locking mechanism, not only can the door body 1 move on the door frame 2, but it can also prevent jamming during the movement. Furthermore, the sealing component can improve its sealing performance. Its overall structure is compact, occupies little space, and has a reasonable design, making it suitable for widespread application.

[0035] Other aspects of this invention that are not detailed herein are conventional techniques known to those skilled in the art, and therefore are not described in detail.

[0036] The scope of protection of this invention is not limited to the technical solutions disclosed in the specific embodiments. The above description is only a preferred embodiment of this invention and does not limit this invention. Any minor modifications, equivalent substitutions and improvements made based on the technical solutions of this invention should be included within the scope of protection of the technical solutions of this invention.
