Description

Technical Field

[0001] This utility model relates to the technical field of protective door sealing structure, specifically a multi-layer composite protective door sealing assembly. Background Technology

[0002] A protective door is a type of door with special protective functions. It is mainly used to block or resist specific environmental factors (such as radiation, gas, liquid, dust, noise, impact, etc.) to ensure the safety or environmental stability of a specific space. The main function of a protective door is to block specific substances or energy. However, gaps can easily appear at the connection between the door and the door frame due to installation errors, door deformation, or wear and tear during opening and closing. Therefore, sealing components are needed to fill these gaps.

[0003] Typical protective door sealing components consist of solid or hollow rubber strips made of elastic materials such as rubber, silicone, and EPDM. These strips fill gaps through compression deformation when the door is closed. Relying solely on the elasticity of the materials themselves, they cannot compensate for larger installation errors or deformations. If the gaps are too small, excessive compression can easily lead to accelerated aging of the rubber strips, while if the gaps are too large, it can cause seal failure. Therefore, a multi-layer composite protective door sealing component is needed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer composite protective door sealing assembly to solve the problem of poor sealing effect mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite protective door sealing assembly, comprising a door frame, a protective door body, a sealing strip, and an airbag.

An adaptive sealing unit is provided inside the sealing groove, and the adaptive sealing unit is provided with an airbag and a sealing strip from the inside to the outside. A boss is provided at the edge of the door frame near the protective door body, and pressure sensors are evenly distributed on the side of the sealing strip near the boss. A miniature air pump is provided at the top of one side of the protective door body, and the output end of the miniature air pump is connected to the airbag via an air guide pipe. A solenoid valve is provided on the air guide pipe.

[0006] As a further technical solution of this utility model, a control box is provided at the center of one side of the protective door body, and a motherboard is provided at the center of the control box. A microprocessor and a wireless communication module are respectively provided on the motherboard.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-6 The present invention provides an embodiment of a multi-layer composite protective door sealing assembly, comprising a door frame 1, a protective door body 2, a sealing strip 10 and an airbag 12, wherein the protective door body 2 is rotatably connected to one side of the inside of the door frame 1 via a hinge 16.

[0024] When closing the protective door body 2, rotate the protective door body 2 so that the protective door body 2 rotates towards the door frame 1 via the hinge 16 until the protective door body 2 is close to the door frame 1;

[0025] A sealing groove 3 is provided on the edge of the protective door body 2 near the door frame 1, and an adaptive sealing unit 7 is provided inside the sealing groove 3.

[0026] The adaptive sealing unit 7 includes a sealing strip 10 and an airbag 12, and a protrusion 4 is provided on the edge of the door frame 1 near the protective door body 2.

[0027] The sealing strip 10 is made of rubber. As the protective door body 2 and the door frame 1 gradually approach each other, the protrusion 4 on the door frame 1 gradually embeds into the sealing groove 3 on the edge of the protective door body 2 and contacts the sealing strip 10 in the adaptive sealing unit 7 in the sealing groove 3. The sealing strip 10 itself serves as the first layer of sealing barrier. It adheres to the protrusion 4 on the door frame 1 with its elasticity, forming the first layer of sealing protection.

[0028] The outer side of the sealing strip 10 is provided with a wear-resistant layer 11, and the wear-resistant layer 11 is a polytetrafluoroethylene coating to improve wear resistance.

[0029] The airbag 12 is located inside the sealing strip 10. A miniature air pump 13 is provided at the top of one side of the protective door body 2. The output end of the miniature air pump 13 is connected to the airbag 12 through the air guide tube 14. A solenoid valve 15 is provided on the air guide tube 14.

[0030] After the airbag 12 is inflated, it can apply pressure to the sealing strip 10 from the inside, making the sealing strip 10 fit more tightly with the boss 4, forming a second layer of sealing protection.

[0031] Pressure sensors 8 are evenly distributed on the side of the sealing strip 10 near the boss 4. The boss 4 is embedded in the sealing groove 3 and contacts the sealing strip 10. The pressure sensors 8 are all thin-film pressure sensors used to sense the pressure brought by the boss 4.

[0032] A control box 17 is provided at the center of one side of the protective door body 2, and a motherboard 18 is provided at the center of the control box 17. A microprocessor 20 and a wireless communication module 19 are respectively provided on the motherboard 18.

[0033] The pressure sensor 8 transmits the pressure signal to the microprocessor 20 on the main board 18 inside the control box 17. The microprocessor 20 analyzes the pressure signal transmitted from the pressure sensor 8.

[0034] If the pressure value does not reach the preset optimal sealing pressure value, a command is sent to the solenoid valve 15 on the micro air pump 13 and the air guide tube 14. After receiving the command, the solenoid valve 15 opens, the micro air pump 13 starts, and inflates the air bag 12 inside the sealing strip 10 through the air guide tube 14. The air bag 12 inflates and expands, generating outward pressure on the sealing strip 10, making the sealing strip 10 fit more tightly with the boss 4.

[0035] Pressure sensor 8 continuously monitors the pressure value and feeds it back to microprocessor 20. When the pressure value monitored by pressure sensor 8 reaches the preset optimal sealing pressure value, microprocessor 20 sends a stop command to micro air pump 13 and solenoid valve 15. Micro air pump 13 stops working, solenoid valve 15 closes, and the pressure in airbag 12 remains stable, ensuring that sealing strip 10 and boss 4 are in the best fit and sealing state. Through the multi-layer composite sealing mechanism, the sealing reliability of the protective door body 2 is greatly improved.

[0036] The door frame 1 has slots 6 on all four sides of one side, and the protective door body 2 has clips 9 on all four sides of the side of the door frame 1.

[0037] As a further technical solution of this utility model, a magnetic part 5 is provided at each of the four corners of the door frame 1 near the protective door body 2, and a magnet piece 22 matching the magnetic part 5 is provided at each of the four corners of the protective door body 2 near the door frame 1.

[0038] After the protective door body 2 is closed, the clips 9 on one side and the slots 6 on one side of the door frame 1 engage with each other. At the same time, the magnetic parts 5 at the four corners of the door frame 1 near the protective door body 2 attract each other with the corresponding magnetic pieces 22 of the protective door body 2, further enhancing the connection and sealing between the protective door body 2 and the door frame 1.

[0039] The wireless communication module 19 inside the control box 17 can wirelessly transmit the working status information of the sealing assembly, such as pressure value and equipment operating status, to an external terminal for remote monitoring.

[0040] The inner wall of the control box 17 is provided with a shielding layer 21, which is made of metal wire braiding, effectively shielding external electromagnetic interference and ensuring the stable operation of internal electronic components such as the motherboard 18.

[0041] The specific models and specifications of the pressure sensor 8, solenoid valve 15, micro air pump 13, microprocessor 20 and wireless communication module 19 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail.

[0042] Working principle: In this embodiment, when the protective door body 2 is closed, the protective door body 2 is rotated, causing it to rotate towards the door frame 1 via the hinge 16 until it approaches the door frame 1. As the protective door body 2 gradually approaches the door frame 1, the protrusion 4 on the door frame 1 gradually embeds into the sealing groove 3 at the edge of the protective door body 2, and contacts the sealing strip 10 in the adaptive sealing unit 7 within the sealing groove 3. The sealing strip 10 itself acts as the first layer of sealing barrier, and its elasticity allows it to adhere to the protrusion 4 on the door frame 1, forming the first layer of sealing protection. At the same time, the air bladder 12 inside the sealing strip 10 expands after inflation, which can protect the sealing strip from the inside. Pressure is applied to make the sealing strip 10 fit more tightly with the boss 4, forming a second layer of sealing protection. The pressure sensors 8, which are evenly distributed on the side of the sealing strip 10 near the boss 4, sense the pressure from the boss 4 and transmit the pressure signal to the microprocessor 20 on the main board 18 inside the control box 17. The microprocessor 20 analyzes the pressure signal from the pressure sensor 8. If the pressure value does not reach the preset optimal sealing pressure value, it sends a command to the solenoid valve 15 on the micro air pump 13 and the air guide tube 14. After receiving the command, the solenoid valve 15 opens, the micro air pump 13 starts, and inflates the air bag 12 inside the sealing strip 10 through the air guide tube 14. The airbag 12 inflates, exerting outward pressure on the sealing strip 10, making the sealing strip 10 fit more tightly against the boss 4. The pressure sensor 8 continuously monitors the pressure value and feeds it back to the microprocessor 20. When the pressure value monitored by the pressure sensor 8 reaches the preset optimal sealing pressure value, the microprocessor 20 sends a stop command to the micro air pump 13 and the solenoid valve 15. The micro air pump 13 stops working, the solenoid valve 15 closes, and the pressure inside the airbag 12 remains stable, ensuring that the sealing strip 10 and the boss 4 are in the optimal sealing state. Through the multi-layer composite sealing mechanism, the reliability of the sealing of the protective door body 2 is greatly improved. During this process, the protective... The latches 9 on one side of the door body 2 and the slots 6 on one side of the door frame 1 engage with each other. At the same time, the magnetic parts 5 at the four corners of the door frame 1 near the protective door body 2 attract each other with the corresponding magnetic pieces 22 of the protective door body 2, further enhancing the sealing between the protective door body 2 and the door frame 1. The wireless communication module 19 in the control box 17 can wirelessly transmit the working status information of the sealing components, such as pressure value and equipment operating status, to an external terminal for remote monitoring. The shielding layer 21 made of woven metal wire on the inner wall of the control box 17 can effectively shield external electromagnetic interference and ensure the stable operation of internal electronic components such as the main board 18.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
