Description

Technical Field

[0001] This utility model relates to the technical field of protective doors, specifically a protective sealing door. Background Technology

[0002] Protective sealing doors, also known as protective airtight doors, are protective devices installed on buildings. They are primarily used to block shock waves and isolate toxic gases. In the event of an emergency, closing the protective airtight door can provide protection and ensure personnel safety. Protective airtight doors can be classified into two types based on materials: steel and reinforced concrete. Steel protective airtight doors are lighter and easier to open and close, and are typically used for larger vehicle entrances and exits. Reinforced concrete doors, due to their greater weight, are generally used for relatively smaller personnel entrances and exits. These doors can be single-leaf or double-leaf designs, depending on the size of the entrance or exit. For example, single-leaf doors are typically used for smaller personnel entrances and exits, while double-leaf doors are used for larger vehicle entrances and exits, as shown below.

[0003] A search revealed a patent document with authorization announcement number CN214786972U, which discloses a sealing structure for a double-leaf protective sealing door, relating to the construction field. The structure includes a door frame, with a first sealing strip fixedly connected to the four sides of the inner wall of the door frame. A first door panel is movably connected to the left side of the inner wall of the front of the door frame, and a second door panel is movably connected to the right side of the inner wall of the front of the door frame. Square grooves are symmetrically formed in the center of the front of the first and second door panels, and a rotating shaft is positioned in the center of the front of each square groove. This invention's sealing structure for a double-leaf protective sealing door prevents gaps from appearing at the top, bottom, and opposite sides of the first and second door panels through the first sealing strip. A first limiting block prevents a first push rod from sliding from the second groove into the first groove. A second limiting block restricts the movement distance of the first push rod. An arc-shaped turntable, by rotating the rotating shaft, pushes the first push rod to eliminate the gap between the two door seams.

[0004] However, existing protective sealing doors still have the following areas for improvement:

[0005] The sealing mechanism used to seal the gap between the protective door body and the door frame mostly uses a sealing gasket that is directly glued and fixed to the protective door body or the door frame. After the protective door body is closed and locked with the door frame, the sealing gasket will be locked in the gap between the protective door body and the door frame to form a seal. However, with the long-term use of the protective door and the increase in the number of opening and closing, the sealing gasket will wear down due to the long-term pressure between the protective door body and the door frame, causing the sealing gasket to become thinner and thinner, or even break and be damaged. At this time, the sealing effect between the protective door body and the door frame after closing will be greatly reduced. Furthermore, the sealing gasket near the hinge components of the protective door body and the door frame is more susceptible to severe pressure and wear. Therefore, its structure needs to be improved and its practicality needs to be enhanced. Utility Model Content

[0006] Technical problems to be solved

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a protective sealing door.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a protective sealing door, including a door frame, a protective door body is hinged to one side of the front of the door frame via a hinge assembly, the front of the protective door body is flush with the front of the door frame, a first sealing mechanism is fixedly installed on the front of the protective door body near its top and bottom ends, the position of the first sealing mechanism matches the top, one side and bottom door gap positions between the protective door body and the door frame, a second sealing mechanism is fixedly installed on the front of the protective door body, the second sealing mechanism is near the hinge assembly, and the position of the second sealing mechanism matches the door gap position between the protective door body and the door frame.

[0010] Furthermore, the protective door body is equipped with a door lock mechanism inside, and the inner side of the door frame is equipped with a locking groove that matches the position of the door lock mechanism.

[0011] Furthermore, the first sealing mechanism includes a mounting plate, spring plates, and an abutment plate. There are two mounting plates, each L-shaped. There are two sets of spring plates, one end of each set of spring plates being fixedly connected to one side of the interior of the two mounting plates. The abutment plate is U-shaped, and one side of the abutment plate is fixedly connected to the end of the two sets of spring plates away from the mounting plate.

[0012] Furthermore, the two mounting plates are respectively fixedly installed on the front of the protective door body near its top and bottom ends. The abutment plate is tightly abutted against the top, one side and bottom door seam positions between the protective door body and the door frame, and a sealing gasket layer is abutted on the side of the abutment plate away from the spring sheet.

[0013] Furthermore, the second sealing mechanism includes a fixed plate, an adjusting wheel rod, a transmission plate, a first sealing plate, and a second sealing plate. One end of the adjusting wheel rod passes through the fixed plate via a screw connection. A plurality of telescopic guide rods are fixedly connected to one side of the transmission plate, and one end of each telescopic guide rod is fixedly connected to the fixed plate. The end of the adjusting wheel rod that passes through the fixed plate is rotatably connected to the transmission plate via a rotating connector. One side of the first sealing plate is fixedly connected to the transmission plate. There are two second sealing plates, and a U-shaped transmission rod is fixedly connected to the top of each of the two second sealing plates. The end of each transmission rod away from the second sealing plate is fixedly connected to the first sealing plate. There is a gap between the second sealing plate and the first sealing plate.

[0014] Furthermore, the fixing plate is fixedly installed on the front of the protective door body. The distance between the first sealing plate and the second sealing plate matches the position of the hinge assembly. Both the first sealing plate and the second sealing plate are close to the door gap between the protective door body and the door frame. Both the first sealing plate and the second sealing plate are fitted with a sealing gasket on the side away from the transmission rod. The sealing gasket on one side of the first sealing plate and the second sealing plate is fitted with the front of the protective door body.

[0015] Beneficial effects:

[0016] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0017] This invention, by incorporating a first sealing mechanism and a second sealing mechanism, ensures that when the protective door is closed, the rebound force generated by the two sets of spring plates in the first sealing mechanism, combined with the two mounting plates, guarantees that the abutment plate can abut and tighten against the top, the side near the door lock mechanism, and the bottom of the door gap between the protective door body and the door frame. This, along with the sealing gasket on one side of the abutment plate, seals the top, the side near the door lock mechanism, and the bottom of the door gap between the protective door body and the door frame. Furthermore, by rotating the adjusting wheel rod in the second sealing mechanism, in conjunction with the telescopic guide rod, the transmission plate moves, thereby moving the first sealing plate. When in use, two transmission rods can be used to drive the two second sealing plates to move synchronously until both the first and second sealing plates move to the door gap between the protective door body and the door frame. At this point, the door gap near the hinge assembly between the protective door body and the door frame can be sealed by the sealing gaskets on one side of the first and second sealing plates. Since the abutment plate, the first sealing plate, and the sealing gaskets on one side of the second sealing plate are located outside the door gap between the protective door body and the door frame, the sealing gaskets will not be subjected to significant wear due to the opening and closing of the protective door body, greatly extending the service life of the sealing gaskets. This effectively avoids the situation where the protective door body and the door frame have poor sealing performance.

[0018] 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] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a protective sealing door, including a door frame 1, a protective door body 3 is hinged to one side of the front of the door frame 1 via a hinge assembly 2, the front of the protective door body 3 is flush with the front of the door frame 1, a first sealing mechanism 4 is fixedly installed on the front of the protective door body 3 near its top and bottom ends, the position of the first sealing mechanism 4 matches the top, one side and bottom door gap positions between the protective door body 3 and the door frame 1, a second sealing mechanism 5 is fixedly installed on the front of the protective door body 3, the second sealing mechanism 5 is near the hinge assembly 2, and the position of the second sealing mechanism 5 matches the door gap position between the protective door body 3 and the door frame 1.

[0026] The protective door body 3 is equipped with a door lock mechanism 6 inside. The door frame 1 has a locking groove 7 on one side inside that matches the position of the door lock mechanism 6, so that the protective door body 3 can be locked and fixed by engaging the door lock mechanism 6 with the locking groove 7.

[0027] The first sealing mechanism 4 includes a mounting plate 401, spring plates 402, and an abutment plate 403. Two mounting plates 401 are provided, each L-shaped. Two sets of spring plates 402 are provided, with one end of each set fixedly connected to the inner side of the two mounting plates 401. The abutment plate 403 is U-shaped, with one side fixedly connected to the end of each set of spring plates 402 away from the mounting plate 401. This ensures that when the protective door body 3 is closed, the rebound force formed by the two sets of spring plates 402 and the two mounting plates 401 guarantees that the abutment plate 403 can be pressed against the top of the protective door body 3 and the door frame 1, close to the door lock. The door gap at one side and bottom of the mechanism 6 is abutted and tightened, thereby cooperating with the sealing gasket on one side of the abutment plate 403 to seal the door gap at the top, the side near the door lock mechanism 6, and the bottom between the protective door body 3 and the door frame 1. Since the sealing gasket on one side of the abutment plate 403 is located outside the door gap between the protective door body 3 and the door frame 1, the sealing gasket on one side of the abutment plate 403 will not be subjected to significant wear due to the opening and closing of the protective door body 3, greatly extending the service life of the sealing gasket on one side of the abutment plate 403. This effectively avoids the situation where the protective door body 3 and the door frame 1 have a poor sealing effect.

[0028] Two mounting plates 401 are fixedly installed on the front of the protective door body 3 near its top and bottom ends respectively. The abutment plate 403 is closely abutted against the top, one side and bottom door seam positions between the protective door body 3 and the door frame 1. The abutment plate 403 is provided with a sealing gasket on the side away from the spring plate 402.

[0029] The second sealing mechanism 5 includes a fixed plate 501, an adjusting wheel rod 502, a transmission plate 503, a first sealing plate 504, and a second sealing plate 505. One end of the adjusting wheel rod 502 passes through the fixed plate 501 via a screw connection. Multiple telescopic guide rods 506 are fixedly connected to one side of the transmission plate 503, with one end of each telescopic guide rod 506 fixedly connected to the fixed plate 501. One end of the adjusting wheel rod 502, passing through the fixed plate 501, is rotatably connected to the transmission plate 503 via a rotating connector. One side of the first sealing plate 504 is fixedly connected to the transmission plate 503. Two second sealing plates 505 are provided, and each of the two second sealing plates 505 has a U-shaped transmission rod 507 fixedly connected to its top. The end of the transmission rod 507 away from the second sealing plate 504 is connected to the first sealing plate 505. A sealing plate 504 is fixedly connected, and a gap is provided between the second sealing plate 505 and the first sealing plate 504. When the protective door body 3 is closed, the adjusting wheel rod 502 can be rotated, and in conjunction with the telescopic guide rod 506, the transmission plate 503 can be moved, thereby moving the first sealing plate 504. When the first sealing plate 504 moves, it can cooperate with the two transmission rods 507 to move the two second sealing plates 505 synchronously until both the first sealing plate 504 and the second sealing plate 505 have moved to the door gap position between the protective door body 3 and the door frame 1. At this time, the door gap near the hinge assembly 2 between the protective door body 3 and the door frame 1 can be sealed by the sealing gasket layer on one side of the first sealing plate 504 and the second sealing plate 505.

[0030] The fixing plate 501 is fixedly installed on the front of the protective door body 3. The spacing between the first sealing plate 504 and the second sealing plate 505 matches the position of the hinge assembly 2. The first sealing plate 504 and the second sealing plate 505 are both close to the door gap between the protective door body 3 and the door frame 1. The side of the first sealing plate 504 and the second sealing plate 505 away from the transmission rod 507 is fitted with a sealing gasket. The sealing gasket on the side of the first sealing plate 504 and the second sealing plate 505 is fitted with the front of the protective door body 3.

[0031] Working principle: When the protective door body 3 is closed, the rebound force formed by the two sets of spring plates 402 and the two mounting plates 401 ensures that the abutment plate 403 can abut and tighten against the top, the side near the door lock mechanism 6, and the bottom of the door gap between the protective door body 3 and the door frame 1. This, combined with the sealing gasket on one side of the abutment plate 403, seals the top, the side near the door lock mechanism 6, and the bottom of the door gap between the protective door body 3 and the door frame 1. Furthermore, rotating the adjusting wheel rod 502, in conjunction with the telescopic guide rod 506, moves the transmission plate 503, thereby moving the first sealing plate 504. When the first sealing plate 504 moves, it can cooperate with the two transmission rods 507 to move the two second sealing plates 504. The sealing plates 505 move synchronously until both the first sealing plate 504 and the second sealing plate 505 move to the door gap between the protective door body 3 and the door frame 1. At this time, the door gap between the protective door body 3 and the door frame 1 near the hinge assembly 2 can be sealed by the sealing gaskets on one side of the first sealing plate 504 and the second sealing plate 505. Since the sealing gaskets on one side of the abutment plate 403, the first sealing plate 504, and the second sealing plate 505 are located outside the door gap between the protective door body 3 and the door frame 1, the sealing gaskets will not be subjected to significant wear due to the opening and closing of the protective door body 3, greatly extending the service life of the sealing gaskets. This effectively avoids the situation where the protective door body 3 and the door frame 1 have poor sealing performance.
