Description

Technical Field

[0001] This application relates to the field of civil defense door technology, and in particular to a civil defense door that is easy to open and close. Background Technology

[0002] The published patent document CN217461933U discloses a convenient-to-open and close air-raid shelter door, specifically relating to the field of air-raid shelter door technology. It includes an installation plate with a door panel rotatably mounted on its front center. A rectangular groove communicating with the rear end is formed on the left front end of the installation plate. A sealing frame is fixedly mounted on the left front end of the installation plate. An installation box is fixedly mounted on the lower front end of the installation plate. A driving device is fixedly mounted on the outer side of the bottom wall of the inner cavity of the installation box, and another driving device is fixedly mounted on the inner side of the bottom wall of the inner cavity of the installation box. This convenient-to-open and close air-raid shelter door utilizes a hydraulic cylinder to raise the height of a first concave support plate, providing stable support for the door panel. When closing the door panel is required, a motor is activated, and a second concave support plate is mechanically connected to rotate the door panel, thereby assisting the operator in closing the rectangular groove and maintaining the integrity of the hinge joint between the door and the door frame, facilitating opening and closing.

[0003] In actual use, the above devices can maintain the integrity of the hinge joint between the door and the door frame and facilitate opening and closing. However, the operators still need to manually open and close the air defense door. Since the air defense door is heavy, the amount of labor required for operators to manually open and close the air defense door is large, which is time-consuming and laborious. Therefore, this application provides an air defense door that is easy to open and close. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a blast door that is easy to open and close, overcoming the deficiencies of existing technologies. It aims to solve the problem that while the above devices can maintain the integrity of the hinge joint between the door body and the door frame and facilitate opening and closing in actual use, the blast door still requires manual operation by the operator. Due to the heavy weight of the blast door, the manual operation by the operator is labor-intensive, time-consuming, and labor-intensive.

[0005] To achieve the above objectives, this application provides the following technical solution: a blast door that is easy to open and close, comprising a mounting plate, wherein the mounting plate has an internal opening, a mounting box is fixedly mounted on one bottom side of the mounting plate, a fixing plate is fixedly mounted on the top of the mounting plate, a rotating roller is rotatably connected to the bottom of the fixing plate, a plurality of sets of hinge blocks are fixedly mounted on the outer surface of the rotating roller, a blast door body is fixedly connected to one side of the plurality of sets of hinge blocks, a groove is provided on the top of the mounting box, an opening and closing mechanism is provided in the groove, the opening and closing mechanism includes two sets of bearing seats, both sets of bearing seats are fixedly mounted in the groove, a rotating shaft is rotatably connected to the top of the bearing seats, a gear is fixedly mounted on the outer surface of the rotating shaft, a motor bracket is fixedly mounted on the bottom of the mounting plate, a reciprocating motor is fixedly mounted on the bottom of the motor bracket, the output end of the reciprocating motor is fixedly mounted to one set of rotating shafts, the other set of rotating shafts is fixedly mounted to the bottom end of the rotating roller, and a belt is connected to the two sets of gears.

[0006] By adopting the above technical solution, when it is necessary to open the air-raid shelter door, the reciprocating motor is started to rotate in the reverse direction, driving a set of rotating shafts to rotate. These shafts, through gears connected to them, mesh with a belt, which in turn drives another set of gears and rotating shafts to rotate, thereby driving a rotating roller to rotate. This roller, through several sets of hinged blocks, drives the air-raid shelter door to open around the roller as its pivot point. Through this opening and closing mechanism, the air-raid shelter door can be automatically opened and closed. This method greatly reduces the labor intensity of operators. When it is necessary to close the air-raid shelter door, starting the reciprocating motor to rotate in the forward direction will cause the air-raid shelter door to be blocked. The opening and closing mechanism then automatically opens and closes the air-raid shelter door, significantly reducing the labor intensity of operators and improving the efficiency of opening and closing the air-raid shelter door.

[0007] As a preferred technical solution of this application, an auxiliary mechanism is provided on the top of the installation box. The auxiliary mechanism includes an electric slide rail, which is fixedly installed on the top of the installation box. An electric slider is slidably connected to the sliding end of the electric slide rail, and a connecting shaft is fixedly installed between the electric slider and the body of the air defense door.

[0008] By adopting the above technical solution, during the opening or closing of the air defense door, the electric slide rail and electric slider provide additional support and guidance for the air defense door body, which improves the support effect of the air defense door body and helps to ensure the smooth opening and closing of the air defense door body.

[0009] As a preferred technical solution of this application, a sealing frame is fixedly installed on one side of the side wall of the mounting plate.

[0010] By adopting the above technical solution, and with the sealing frame located on the contact surface of the air-raid shelter door body when closed, it is beneficial to ensure the sealing between the air-raid shelter door body and the mounting plate when closed, preventing external air, moisture or harmful substances from entering the air-raid shelter area, and improving safety during use.

[0011] As a preferred technical solution of this application, a controller is fixedly installed on the top of the motor bracket, and an operator is fixedly installed on both sides of the air defense door body. The operator, auxiliary mechanism, and reciprocating motor are all electrically connected to the controller.

[0012] By adopting the above technical solution, the operator sends instructions through the operator, and the controller controls the operation of the reciprocating motor and auxiliary mechanism after receiving the instructions, which makes it easier for the operator to control the opening and closing of the air defense door body and improves the convenience of controlling the opening and closing of the air defense door body.

[0013] As a preferred technical solution of this application, an infrared sensor is fixedly installed on the top of the air defense door body, and the infrared sensor is electrically connected to the controller.

[0014] By adopting the above technical solution, when the infrared sensor detects the sealing frame, the infrared sensor will immediately send a signal to the controller, and the controller will control the reciprocating motor to stop running, thereby effectively covering the body of the air defense door.

[0015] As a preferred technical solution of this application, two sets of ultrasonic sensors are fixedly installed on both sides of the air defense door body. The ultrasonic sensors are located below the operator and are electrically connected to the controller.

[0016] By adopting the above technical solution, ultrasonic sensors are used to detect whether there are obstacles on both sides of the blast door body, preventing accidents during automatic opening and closing. When the ultrasonic sensor detects an obstacle, it will immediately send a signal to the controller, which will control the reciprocating motor to stop running, thereby stopping the movement of the blast door body and improving the safety of the blast door body during automatic opening and closing.

[0017] As a preferred technical solution of this application, an alarm is fixedly installed on the front surface of the air defense door body, located diagonally above the operator, and the alarm is electrically connected to the controller.

[0018] By adopting the above technical solution, when the ultrasonic sensor detects an abnormality, it will immediately send a signal to the controller, which will then activate the alarm, thus helping to promptly remind operators to identify and resolve the problem.

[0019] As a preferred technical solution of this application, a protective cover and a protective cover are fixedly installed on the top of the mounting box, the protective cover covering the groove above the groove and the protective cover covering the electric slide rail above the groove.

[0020] By adopting the above technical solutions, the opening and closing mechanism is protected by a protective cover, and the electric slide rail is protected by a protective cover. This helps to improve the safety of the opening and closing mechanism and the auxiliary mechanism, and extend their service life.

[0021] The beneficial effects of this application are:

[0022] 1. When the air-raid shelter door needs to be opened, the reciprocating motor is started to rotate in the reverse direction, driving a set of rotating shafts to rotate. These shafts, through connected gears, mesh with a belt, which in turn drives another set of gears and rotating shafts to rotate, thereby driving a rotating roller to rotate. This roller, through several sets of hinged blocks, opens the air-raid shelter door around its pivot point. Through this opening and closing mechanism, the air-raid shelter door can be opened and closed automatically. This method greatly reduces the workload of operators. When the air-raid shelter door needs to be closed, the reciprocating motor is started to rotate in the forward direction, which in turn drives the door to close automatically. The opening and closing mechanism further reduces the workload of operators and improves the efficiency of opening and closing the air-raid shelter door.

[0023] 2. During the opening or closing of the air-raid shelter door, the electric slide rail and electric slider provide additional support and guidance to the air-raid shelter door body, which improves the support effect of the air-raid shelter door body and helps to ensure the smooth opening and closing of the air-raid shelter door body.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A type of air-raid shelter door that is easy to open and close includes a mounting plate 1. The mounting plate 1 has an internal opening 101. A mounting box 2 is fixedly mounted on one bottom side of the mounting plate 1. A fixing plate 3 is fixedly mounted on the top of the mounting plate 1. A rotating roller 4 is rotatably connected to the bottom of the fixing plate 3. Several sets of hinge blocks 5 are fixedly mounted on the outer surface of the rotating roller 4. An air-raid shelter door body 6 is fixedly connected to one side of each set of hinge blocks 5. A groove 7 is provided on the top of the mounting box 2. An opening and closing mechanism 8 is provided in the groove 7. The opening and closing mechanism 8 includes two sets of bearing seats 801. All are fixedly installed in the groove 7. The top of the bearing seat 801 is rotatably connected to the rotating shaft 802. The outer surface of the rotating shaft 802 is fixedly installed with gear 803. The bottom of the mounting plate 1 is fixedly installed with the motor bracket 805. The bottom of the motor bracket 805 is fixedly installed with the reciprocating motor 806. The output end of the reciprocating motor 806 is fixedly installed with one set of rotating shafts 802. The other set of rotating shafts 802 is fixedly installed at the bottom end of the rotating roller shaft 4. The two sets of gears 803 are connected by a belt 804. The side wall of the mounting plate 1 is fixedly installed with a sealing frame 12 on one side of 101.

[0031] When it is necessary to open the main body 6 of the air defense door, the reciprocating motor 806 is started to rotate in the reverse direction, which drives a set of rotating shafts 802 to rotate. The rotating shafts 802 rotate through the gears 803 connected to them and mesh with the belt 804, which in turn drives another set of gears 803 and rotating shafts 802 to rotate, thereby driving the rotating roller shaft 4 to rotate. The rotating roller shaft 4 drives the main body 6 of the air defense door to open around the rotating roller shaft 4 as the axis through several sets of hinge blocks 5. Through the opening and closing mechanism 8, the main body 6 of the air defense door can be opened and closed automatically. This method greatly reduces the labor intensity of operators. When it is necessary to close the air defense door body 6, starting the reciprocating motor 806 to rotate in the forward direction will link the air defense door body 6 to block 101. The opening and closing mechanism 8 realizes the automatic opening and closing of the air defense door body 6, which greatly reduces the labor intensity of operators and improves the opening and closing efficiency of the air defense door body 6. The sealing frame 12 is located on the contact surface when the air defense door body 6 is closed, which helps to ensure the sealing between the air defense door body 6 and the mounting plate 1 in the closed state, preventing external air, moisture or harmful substances from entering the air defense area and improving the safety during use.

[0032] Reference Figure 1-3 An auxiliary mechanism 9 is provided on the top of the installation box 2. The auxiliary mechanism 9 includes an electric slide rail 901, which is fixedly installed on the top of the installation box 2. An electric slider 902 is slidably connected to the sliding end of the electric slide rail 901. A coupling 903 is fixedly installed between the electric slider 902 and the body of the air defense door 6. A controller 10 is fixedly installed on the top of the motor bracket 805. An operator 11 is fixedly installed on both sides of the air defense door body 6. The operator 11, the auxiliary mechanism 9, and the reciprocating motor 806 are all electrically connected to the controller 10.

[0033] During the opening or closing of the air-raid shelter door body 6, the electric slide rail 901 and electric slider 902 provide additional support and guidance for the air-raid shelter door body 6, improving the support effect of the air-raid shelter door body 6 and helping to ensure the smooth opening and closing of the air-raid shelter door body 6; the operator sends instructions through the operator 11, and the controller 10 controls the operation of the reciprocating motor 806 and the auxiliary mechanism 9 after receiving the instructions, which makes it easier for the operator to control the opening and closing of the air-raid shelter door body 6 and improves the convenience of controlling the opening and closing of the air-raid shelter door body 6.

[0034] Reference Figure 1-3An infrared sensor 13 is fixedly installed on the top of the air-raid shelter door body 6, and the infrared sensor 13 is electrically connected to the controller 10. An alarm 15 is fixedly installed on the front surface of the air-raid shelter door body 6, diagonally above the operator 11, and the alarm 15 is electrically connected to the controller 10. When the infrared sensor 13 detects the sealing frame 12, the infrared sensor 13 will immediately send a signal to the controller 10, and the controller 10 will control the reciprocating motor 806 to stop running, so that the air-raid shelter door body 6 can effectively cover 101. When the ultrasonic sensor 14 detects an abnormality, the ultrasonic sensor 14 will immediately send a signal to the controller 10, and the controller 10 will control the alarm 15 to start immediately, which is conducive to timely reminder to the operator to find and solve the problem.

[0035] Reference Figure 2-4 Two sets of ultrasonic sensors 14 are fixedly installed on both sides of the air-raid shelter door body 6. The ultrasonic sensors 14 are located below the operator 11 and are electrically connected to the controller 10. Protective covers 16 and 17 are fixedly installed on the top of the mounting box 2. Protective cover 16 covers the groove 7 and protective cover 17 covers the electric slide rail 901. The ultrasonic sensors 14 detect whether there are obstacles on both sides of the air-raid shelter door body 6 to prevent accidents during automatic opening and closing. When the ultrasonic sensors 14 detect an obstacle, they will immediately send a signal to the controller 10. The controller 10 will control the reciprocating motor 806 to stop running, thereby stopping the movement of the air-raid shelter door body 6 and improving the safety of the automatic opening and closing process of the air-raid shelter door body 6. The protective cover 16 protects the opening and closing mechanism 8 and the protective cover 17 protects the electric slide rail 901, which helps to improve the safety of the opening and closing mechanism 8 and the auxiliary mechanism 9 and extend their service life.

[0036] Working principle: When the air defense door body 6 needs to be opened, the reciprocating motor 806 is started to rotate in the reverse direction, driving a set of rotating shafts 802 to rotate. The rotating shafts 802 rotate through the gears 803 connected to them and mesh with the belt 804, which in turn drives another set of gears 803 and rotating shafts 802 to rotate, thereby driving the rotating roller 4 to rotate. The rotating roller 4 drives the air defense door body 6 to open around the rotating roller 4 as the pivot point through several sets of hinge blocks 5. Through the opening and closing mechanism 8, the air defense door body 6 can achieve automatic opening and closing. This method greatly reduces the labor intensity of operators. When the air defense door body 6 needs to be closed, the reciprocating motor 806 is started to rotate in the forward direction, which will drive the air defense door body 6 to block 101. During the opening or closing process of the air defense door body 6, the electric slide rail 901 and electric slider 902 provide additional support and guidance for the air defense door body 6.

[0037] The sealing frame 12 is located on the contact surface of the air defense door body 6 when it is closed, which helps to ensure the sealing between the air defense door body 6 and the mounting plate 1 when it is closed, preventing external air, moisture or harmful substances from entering the air defense area. The operator sends instructions through the operator 11, and the controller 10 controls the operation of the reciprocating motor 806 and the auxiliary mechanism 9 after receiving the instructions, so that the operator can control the opening and closing of the air defense door body 6.

[0038] Simultaneously, when the infrared sensor 13 detects the sealing frame 12, it immediately sends a signal to the controller 10. The controller 10 then controls the reciprocating motor 806 to stop running, thereby effectively covering 101 with the body of the air defense door 6. The ultrasonic sensor 14 detects whether there are obstacles on both sides of the air defense door body 6 to prevent accidents during automatic opening and closing. When the ultrasonic sensor 14 detects an obstacle, it immediately sends a signal to the controller 10, which then controls the reciprocating motor 806 to stop running, thereby stopping the movement of the air defense door body 6.

[0039] In addition, when the ultrasonic sensor 14 detects an abnormality, the ultrasonic sensor 14 will immediately send a signal to the controller 10, and the controller 10 will control the alarm 15 to start immediately; the opening and closing mechanism 8 is protected by the protective cover 16, and the electric slide rail 901 is protected by the protective cover 17.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
