Technical Field

[0001] This application relates to the technical field of self-warning air defense doors, and specifically to a self-warning air defense door with a vertical support function. Background Art

[0002] An air defense door refers to a specially designed door product, whose main function is for personal safety and response to emergencies. It is usually used in public places, commercial buildings, residential areas, etc. Most of them have the functions of fire and explosion prevention, air and water blocking, to prevent illegal intrusion and protect the safety of internal personnel. Modern air defense doors will install a self-warning function to enhance safety and provide timely warnings and responses in case of threats or emergencies.

[0003] For example, the Chinese patent (Publication No.: CN221256562U) discloses a self-warning air defense door, including a base. The right side of the base is fixedly connected with a door shaft column, the left side of the base is filed and connected with a door column, the left side of the door shaft column is fixedly connected with a cross beam, the inner wall of the door shaft column is rotatably connected with a rotating shaft, the outside of the rotating shaft is fixedly connected with a housing, the front end of the housing is fixedly connected with a door panel, the middle of the rear side of the housing is rotatably connected with a rotating rod, the front side of the outside of the rotating rod is fixedly connected with a gear, the rear end of the rotating rod is fixedly connected with a turntable, and both the left and right sides of the inner wall of the housing are fixedly connected with partitions. The inner walls of the opposite sides of the two partitions are both slidably connected with lifting blocks, realizing the fixed function of the self-warning air defense door in the vertical direction, improving the protection intensity, realizing the buffering function of the front and rear sides of the door panel and the housing, and improving the service life of the self-warning air defense door.

[0004] However, there are still some deficiencies in the above-mentioned retrieved patent. When in use, it needs to manually operate the switch component to lock and fix the door panel, which reduces the convenience of using the air defense door and is somewhat inconvenient to use. Therefore, this application proposes a self-warning air defense door with a vertical support function to solve the above problems. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, this application provides a self-warning air defense door with a vertical support function, which has the advantages of automatically opening and closing the door panel and better operation convenience, and solves the problem that the device disclosed in the above-mentioned retrieved patent needs manual operation and has poor convenience.

[0006] To achieve the above object, the present application provides the following technical solutions: An autonomous warning civil air defense door with vertical support function, comprising a door frame, two connecting rods hinged to the front of the door frame, a door panel fixed to the ends of the two connecting rods away from the door frame, a storage bin fixed to the top surface of the door frame, a hydraulic cylinder hinged to the inner top wall of the storage bin and having one end hinged to the front of the door panel, a locking mechanism arranged on the door frame, and a sealing mechanism arranged on the door frame;

[0007] The locking mechanism includes cylinders fixed to the left and right sides of the door frame, a connecting plate fixed to the opposite sides of the two cylinders, a horizontal support rod fixed to the opposite sides of the two connecting plates, a pressing block fixed to the opposite sides of the two connecting plates, a vertical support rod slidably connected to the inner walls of the upper and lower sides of the door frame, and a reset assembly arranged on the vertical support rod. Two U-shaped grooves for accommodating the locking mechanism are formed in the door frame. Support grooves are formed on the upper and lower sides and the left and right sides of the door panel.

[0008] With the above technical solutions, during use, the hydraulic cylinder can drive the door panel to flip to achieve autonomous opening and closing. When the door panel flips to the inner side of the door frame, the locking mechanism can automatically control the horizontal support rod and the vertical support rod to move and insert into the door panel, which not only plays a role in limiting and fixing the door panel but also enhances the support effect on the door panel, improves the support force of the door panel, and ensures the stability of the door panel. It has better practicability and is more convenient for popularization and use.

[0009] Further, the reset assembly includes a guide plate fixed to the side of the vertical support rod facing the pressing block, a guide rod fixed to the inner wall of the U-shaped groove and slidably connected to the guide plate, and a tension spring sleeved on the outer peripheral wall of the guide rod.

[0010] With the above technical solutions, the horizontal support rod and the vertical support rod play a role in limiting and fixing and supporting the door panel. When the door panel needs to be opened, the cylinders contract to drive the horizontal support rods on both sides to move away from each other, and at the same time, the tension spring drives the guide plate to move to the side away from the door panel, thereby driving the vertical support rod to disengage from the door panel so that the hydraulic cylinder can control the door panel to flip open.

[0011] Further, the sealing mechanism includes a pressing rod fixed to the opposite sides of the two connecting plates, a piston plate fixed to the end of the pressing rod away from the connecting plate, a compression chamber slidably connected to the outer peripheral wall of the piston plate and fixed to the inner wall of the U-shaped groove, a connecting pipe fixed to the side of the compression chamber away from the connecting plate, and a sealing capsule fixed between the connecting pipes on both sides. Two sealing grooves are formed on the inner wall of the door frame.

[0012] With the above technical solution, when the locking mechanism needs to lock the door panel, the cylinder drives the connecting plates on both sides to move relative to each other. The connecting plates on both sides will also cause the piston plate to press the air inside the two compression chambers into the sealing bag, so that the sealing bag expands and contacts the side wall of the door panel better for sealing.

[0013] Furthermore, the connecting rod is a U-shaped rod, the bottom surface of the storage bin is open, the storage bin is connected to the door frame in an L shape, the hydraulic cylinder, the storage bin and the door panel are connected in a right triangle, and the hydraulic cylinder is the hypotenuse of the right triangle.

[0014] With the above technical solution, it is convenient to drive the door panel to flip through the set hydraulic cylinder and the connecting rod, so as to achieve the effect of automatically opening and closing the civil air defense door.

[0015] Furthermore, the two U-shaped grooves are opposite to each other left and right. The opposite ends of the two cylinders respectively extend into the two U-shaped grooves, and the connecting plate and the two extrusion blocks are connected in a U shape.

[0016] With the above technical solution, it is convenient to drive the connecting plates on both sides to move relative to or away from each other inside the U-shaped groove through the two set cylinders, so as to realize the locking or unlocking effect of the door panel.

[0017] Furthermore, sliding holes for the horizontal support rod and the vertical support rod to penetrate are formed on the inner wall of the door frame. The U-shaped groove is communicated with the sliding hole, and four horizontal support rods and four vertical support rods are provided.

[0018] With the above technical solution, it is convenient to support and limit the upper, lower, left and right four sides of the door panel through the set horizontal support rod and vertical support rod, and improve the stability of the door panel.

[0019] Furthermore, the guide rod is vertically arranged. The tension spring is arranged on the side of the guide plate away from the extrusion block. One end of the tension spring is fixed to the guide plate and the other end is fixed to the inner wall of the U-shaped groove.

[0020] With the above technical solution, it is convenient to stretch the tension spring while the extrusion block squeezes the vertical support rod to move towards the door panel side, so as to facilitate the reset of the vertical support rod by the tension spring when the door panel is opened.

[0021] Furthermore, a sealing ring is fixed on the outer peripheral wall of the piston plate. The sealing bag is an annular rubber air bag, the sealing groove is an annular groove, two sealing bags are provided and are respectively located in the two sealing grooves, and eight connecting pipes are provided and are respectively communicated with the two sealing bags.

[0022] With the above technical solution, it is convenient to form two seals on the outer peripheral wall of the door panel through the two set sealing bags, effectively improving the sealing effect between the door panel and the door frame.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] 1. When the self-warning civil air defense door with vertical support function is in use, the hydraulic cylinder can drive the door panel to flip to achieve automatic opening and closing. When the door panel flips to the inner side of the door frame, the locking mechanism can automatically control the horizontal support rod and the vertical support rod to move and insert into the door panel, which not only limits and fixes the door panel but also enhances the support effect on the door panel, improves the support force of the door panel, ensures the stability of the door panel, has better practicability, and is more convenient for popularization and use.

[0025] 2. When the locking mechanism locks the door panel, it will also drive the piston plate of the sealing mechanism to move, and then inflate the sealing capsule through the cooperation of the piston plate and the compression chamber, so that the sealing capsule expands and better contacts the side wall of the doorknob, effectively improving the sealing effect between the door panel and the door frame, increasing the fire and explosion prevention, airtight and water-proof effects of the civil air defense door, and enhancing the safety of the civil air defense door.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0033] Please refer to Figures 1 to 2 , a self-warning civil air defense door with a vertical support function in this embodiment, includes a door frame 1, two connecting rods 2 hinged to the front of the door frame 1, a door panel 3 fixed to the ends of the two connecting rods 2 away from the door frame 1, a storage bin 4 fixed to the top surface of the door frame 1, a hydraulic cylinder 5 hinged to the inner top wall of the storage bin 4 and having one end hinged to the front of the door panel 3, a locking mechanism 6 provided on the door frame 1, and a sealing mechanism 7 provided on the door frame 1. When in use, the hydraulic cylinder 5 can drive the door panel 3 to flip to achieve automatic opening and closing. When the door panel 3 flips to the inside of the door frame 1, the locking mechanism 6 can automatically limit and fix the door panel 3 while enhancing the support effect on the door panel 3, improving the support force of the door panel 3 to ensure the stability of the door panel 3. When the locking mechanism 6 locks the door panel 3, it will also drive the sealing mechanism 7 to seal the side wall of the door panel 3, effectively improving the sealing effect between the door panel 3 and the door frame 1, increasing the fire and explosion prevention, air blocking and water isolation effects of the civil air defense door, and enhancing the safety of the civil air defense door.

[0034] It should be noted that the control mode of the present application is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present application is mainly used to protect mechanical devices, so the control mode and circuit connection of the present application will not be explained in detail.

[0035] The connecting rod 2 is a U-shaped rod. The bottom surface of the storage bin 4 is open. The storage bin 4 is connected to the door frame 1 in an L shape. The hydraulic cylinder 5, the storage bin 4 and the door panel 3 are connected in a right triangle, and the hydraulic cylinder 5 is the hypotenuse of the right triangle.

[0036] Please refer to Figures 1 to 3, the locking mechanism 6 includes cylinders 601 fixed to the left and right sides of the door frame 1, a connecting plate 602 fixed to the opposite sides of the two cylinders 601, a horizontal support rod 603 fixed to the opposite sides of the two connecting plates 602, a pressing block 604 fixed to the opposite sides of the two connecting plates 602, a vertical support rod 605 slidably connected to the inner walls of the upper and lower sides of the door frame 1, and a reset assembly provided on the vertical support rod 605. Two U-shaped grooves 606 for accommodating the locking mechanism 6 are formed in the door frame 1. Support grooves 607 are formed on the upper and lower sides and the left and right sides of the door panel 3. When the door panel 3 is in a vertically closed state, the cylinders 601 push the connecting plates 602 on both sides to move relatively. The connecting plates 602 drive the horizontal support rods 603 on the left and right sides to move relatively and insert into the support grooves 607 on the left and right sides of the door panel 3. At the same time, the connecting plates 602 drive the pressing blocks 604 to move. The pressing blocks 604 press the vertical support rods 605 on the upper and lower sides, so that the vertical support rods 605 on the upper and lower sides move relatively and insert into the support grooves 607 on the upper and lower sides of the door panel 3. Thus, the horizontal support rods 603 and the vertical support rods 605 play a role in limiting and fixing the door panel 3 and supporting it.

[0037] In this embodiment, the two U-shaped grooves 606 are opposite to each other left and right. The opposite ends of the two cylinders 601 respectively extend into the two U-shaped grooves 606. The connecting plate 602 and the two pressing blocks 604 are connected in a U shape. Such a structure facilitates the cylinders 601 to drive the connecting plate 602 to move left and right inside the U-shaped grooves 606, thereby completing the locking and unlocking operations of the door panel 3. Slide holes for the horizontal support rod 603 and the vertical support rod 605 to penetrate are formed on the inner wall of the door frame 1. The U-shaped grooves 606 are communicated with the slide holes. Four horizontal support rods 603 and four vertical support rods 605 are provided. The horizontal support rods 603 and the vertical support rods 605 provided play a role in supporting and limiting the upper, lower, left, and right four sides of the door panel 3, increasing the stability of the door panel 3.

[0038] Please refer to Figure 3, in this embodiment, the reset assembly includes a guide plate 608 fixed to the side of the vertical support rod 605 facing the extrusion block 604, a guide rod 609 fixed to the inner wall of the U-shaped groove 606 and slidably connected to the guide plate 608, and a tension spring 610 sleeved on the outer peripheral wall of the guide rod 609. The guide rod 609 is vertically arranged, and the tension spring 610 is arranged on the side of the guide plate 608 away from the extrusion block 604. One end of the tension spring 610 is fixed to the guide plate 608 and the other end is fixed to the inner wall of the U-shaped groove 606. When the vertical support rod 605 moves towards the door panel 3, it will drive the guide plate 608 to slide along the guide rod 609 and simultaneously stretch the tension spring 610. When it is necessary to open the door panel 3, the cylinder 601 contracts, driving the two side horizontal support rods 603 to move away from each other. At the same time, the extrusion block 604 disengages from the vertical support rod 605. Since the tension spring 610 is stretched, it will generate an elastic force. After losing the extrusion force of the extrusion block 604, it will drive the guide plate 608 to move towards the side away from the door panel 3, thereby driving the vertical support rod 605 to disengage from the door panel 3, so that the hydraulic cylinder 5 can control the door panel 3 to flip and open.

[0039] Please refer to Figures 4 to 5 , in this embodiment, the sealing mechanism 7 includes an extrusion rod 701 fixed to the opposite sides of the two connecting plates 602, a piston plate 702 fixed to the end of the extrusion rod 701 away from the connecting plate 602, a compression chamber 703 slidably connected to the outer peripheral wall of the piston plate 702 and fixed to the inner wall of the U-shaped groove 606, a connecting pipe 704 fixed to the side of the compression chamber 703 away from the connecting plate 602, and a sealing bladder 705 fixed between the two connecting pipes 704. Two sealing grooves 706 are opened on the inner wall of the door frame 1. When the locking mechanism 6 needs to lock the door panel 3, the cylinder 601 drives the two side connecting plates 602 to move relatively. The two side connecting plates 602 will also drive the two side piston plates 702 to slide relatively inside the two compression chambers 703 through the extrusion rods 701. As a result, the piston plate 702 presses the air inside the two compression chambers 703 into the sealing bladder 705 through the connecting pipe 704, causing the sealing bladder 705 to expand and better contact the side wall of the door panel 3 for sealing.

[0040] In this embodiment, a sealing ring is fixed to the outer peripheral wall of the piston plate 702. The sealing bladder 705 is an annular rubber air bladder. The sealing groove 706 is an annular groove. There are two sealing bladders 705 and they are respectively located in the two sealing grooves 706. There are eight connecting pipes 704 in total and they are respectively communicated with the two sealing bladders 705.

[0041] The working principle of the above embodiment is:

[0042] (1)During use, the hydraulic cylinder 5 is activated. The hydraulic cylinder 5 extends and retracts, thereby driving the door panel 3 to flip in cooperation with the connecting rod 2 to achieve the effect of automatic opening and closing. When the door panel 3 is in a vertically closed state, the air cylinder 601 pushes the connecting plates 602 on both sides to move relatively. The connecting plates 602 drive the horizontal support rods 603 on the left and right sides to move relatively and insert into the inner parts of the support grooves 607 on the left and right sides of the door panel 3. At the same time, the connecting plates 602 drive the extrusion blocks 604 to move. The extrusion blocks 604 extrude the vertical support rods 605 on the upper and lower sides, causing the vertical support rods 605 on the upper and lower sides to move relatively and insert into the inner parts of the support grooves 607 on the upper and lower sides of the door panel 3. Thus, the horizontal support rods 603 and the vertical support rods 605 play a role in limiting, fixing, and supporting the door panel 3. When the vertical support rods 605 move towards the door panel 3, they will drive the guide plates 608 to slide along the guide rods 609 and stretch the tension springs 610 simultaneously. When it is necessary to open the door panel 3, the air cylinder 601 contracts, driving the horizontal support rods 603 on both sides to move away from each other. At the same time, the extrusion blocks 604 are separated from the vertical support rods 605. Since the tension springs 610 are stretched, they will generate elastic force. After losing the extrusion force of the extrusion blocks 604, they will drive the guide plates 608 to move towards the side away from the door panel 3, thereby driving the vertical support rods 605 to disengage from the door panel 3, so that the hydraulic cylinder 5 can control the door panel 3 to flip open;

[0043] (2)When the locking mechanism 6 needs to lock the door panel 3, the air cylinder 601 drives the connecting plates 602 on both sides to move relatively. The connecting plates 602 on both sides will also drive the piston plates 702 on both sides to slide relatively inside the two compression chambers 703 through the extrusion rods 701. Thus, the piston plates 702 press the air inside the two compression chambers 703 into the sealing capsule 705 through the connecting pipes 704, causing the sealing capsule 705 to expand and better contact the side wall of the door panel 3 for sealing.
