Description

Technical Field

[0001] This utility model relates to the field of civil defense door equipment technology, and in particular to a novel sliding rail civil defense door. Background Technology

[0002] Civil defense doors refer to the doors at the entrances and exits of civil defense projects. Civil defense doors have functions such as waterproofing, explosion-proofing, and air pollution resistance, and play a vital role, especially in dangerous situations. Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are clearly classified, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, and other civil defense equipment.

[0003] In practice, existing technologies for opening air-raid shelter doors that require manual pulling present several problems: the lack of limiters when multiple doors slide makes it difficult to manually control the sliding speed, posing safety hazards; it also makes it inconvenient for remote staff to monitor and handle the situation on-site at any time, resulting in low overall flexibility of the equipment.

[0004] Therefore, this utility model provides a novel sliding rail type air defense door. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a new type of sliding rail-type air defense door.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel sliding rail type air defense door, including a fixed base plate,

[0007] The top of the fixed base plate is equipped with a first security wall and a second security wall. The second security wall is located on one side of the first security wall. A first limiting frame is installed on one side of both the first and second security walls. A limiting slide rail is installed inside each of the two first limiting frames. A security door is slidably connected inside the limiting slide rail. A security net is installed inside the security door. Movable rollers are installed at equal intervals at the bottom of the security door and are located inside the limiting slide rail. The sliding trajectory of the movable rollers is limited by the limiting slide rail.

[0008] A second limiting frame is installed on the top of the fixed base plate and on the outside of the security door. The second limiting frame is located between the two first limiting frames. Mounting clamps are installed inside the two first limiting frames and on both sides of the security door. Limiting rollers for use with the security door are installed on the top of the mounting clamps. Mounting clamps and limiting rollers of the same structure are installed inside the second limiting frame. The sliding trajectory of the security door is limited by the limiting rollers.

[0009] The top of the first security wall is equipped with a mounting bracket, and a surveillance camera is installed inside the mounting bracket;

[0010] A limiting mechanism is installed on the side of the security door away from the second security wall. This limiting mechanism includes a positioning frame. An installation frame is installed on the side of the security door away from the second security wall, and the positioning frame is installed on one side of the installation frame. The positioning frame has an L-shaped structure, which facilitates equipment connection. A movable slider is fitted onto the outer side of the installation frame. An installation plate is installed inside the movable slider, located on one side of the installation frame. A limiting roller for use with the installation frame is installed inside the installation plate. A connecting rod is fixedly connected to the bottom of the installation plate, and a fixing block is fixedly connected to one end of the connecting rod. One side of the fixing block is fixedly connected to the security door. The positioning frame has a sliding plate inside, one side of which is connected to a sliding block. The outer side of the sliding block is threaded with a third positioning bolt that matches the positioning of the mounting sleeve. The third positioning bolt positions the mounting sleeve and the sliding block, ensuring that when the security door slides, the fixed block will slide to one side. With the connection of the connecting rod, the sliding block will slide outside the mounting frame, the limit roller will roll on one side of the mounting frame, and the sliding plate will slide inside the positioning frame. Through multiple sliding, the device has a buffering effect when the security door slides, and it is convenient for subsequent normal reset. The overall structure does not use a lot of electrical equipment, saving the overall use and installation costs.

[0011] In a preferred embodiment, the top of the positioning frame and the side away from the movable slide plate are provided with equally spaced mounting slots. Each mounting slot is threaded with a second positioning bolt extending into the fixed base plate. These second positioning bolts secure the positioning frame to the fixed base plate, improving the stability of the limiting rollers during movement. The second positioning bolts can be tightened all the way into the mounting slots during installation, preventing collisions during the movable slide plate's movement and extending the equipment's service life. The bottom of each of the first limiting frames is fitted with symmetrically distributed first mounting base plates, all connected to the top of the fixed base plate. Similarly, the bottom of each of the second limiting frames is fixedly connected with symmetrically distributed second mounting base plates, all connected to the top of the fixed base plate. The second mounting base plates provide auxiliary support for the entire second limiting frame, while the first mounting base plates provide auxiliary support for the entire first limiting frame.

[0012] In a preferred embodiment, a battery storage compartment is fixedly connected to the top of the first security wall, located on the side away from the mounting frame. A lighting lamp is fixedly connected to the top of the battery storage compartment. The top of the second security wall is equipped with a battery storage compartment and a lighting lamp of the same structure. Both battery storage compartments contain batteries. The battery storage compartments and batteries work together with the power supply of the overall power equipment. The lighting lamp provides auxiliary lighting to facilitate nighttime operations. A positioning side plate is fixedly connected to one side of each of the two mounting frames. The positioning side plate is located on one side of the first security wall. The outer side of the positioning side plate is threaded with a first positioning bolt extending into the interior of the first security wall. The positioning side plate and the first security wall are positioned and installed by the first positioning bolt, thereby achieving the installation effect of the mounting frame and the first security wall. The top of the second security wall is equipped with a mounting frame and a monitoring camera of the same structure.

[0013] In a preferred embodiment, each of the two mounting brackets has a connecting plate fixedly connected inside. One side of each of the two connecting plates is fixedly connected to a positioning side plate, and the other side of each of the two connecting plates is connected to a monitoring camera. The monitoring camera is rotatably connected to the connecting plate, and the installation position of the monitoring camera is limited by the connecting plate, which facilitates the adjustment of the monitoring position during use.

[0014] In a preferred embodiment, a fixing rod is installed inside the second limiting frame, and a counterweight is fixedly connected to the top of the fixing rod. A wireless transceiver is installed on the top of the counterweight, and a main control board is installed inside the wireless transceiver. A control chip is fixedly connected to the outside of the main control board. The battery compartment, lighting, monitoring camera, and wireless transceiver are all electrically connected to the control chip. The control chip is used to control the operation of the battery compartment, lighting, monitoring camera, and wireless transceiver, thereby realizing unified management of power equipment.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] By setting up a fixed base plate, a first security wall, a second security wall, and a limiting mechanism, both battery compartments are equipped with batteries during use. The power supply from the battery compartments and batteries, along with auxiliary lighting, facilitates nighttime operations. The second limiting frame contains a similarly structured mounting plate and limiting rollers. These rollers limit the sliding trajectory of the security door. A third positioning bolt positions the mounting plate and the movable slider, ensuring that when the security door slides, it drives the fixed block to slide to one side. Connected by a connecting rod, this causes the movable slider to slide outside the mounting frame, and the limiting rollers... The rolling and moving slide plate on one side of the mounting frame slides inside the positioning frame. Through multiple sliding mechanisms, it provides a buffering effect when the security door slides, while also facilitating subsequent normal reset. The overall structure does not use a large amount of electrical equipment, saving on overall usage and installation costs. Multiple second positioning bolts are used to position the positioning frame and the fixed base plate, improving the stability of the limit roller movement. The connecting plate limits the installation position of the surveillance camera, facilitating the adjustment of the monitoring position during use. This achieves normal security while also enabling convenient remote monitoring of the site. The multiple limiting sliding mechanisms prevent excessive speed during sliding, thus avoiding potential safety hazards, and also facilitate subsequent normal reset. Attached Figure Description

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.

[0031] like Figures 1-6 As shown, this embodiment provides a technical solution: a novel sliding rail type air-raid shelter door, including a fixed base plate 1, a first security wall 2 and a second security wall 3 installed on the top of the fixed base plate 1, the second security wall 3 located on one side of the first security wall 2, a first limiting frame 41 installed on one side of both the first security wall 2 and the second security wall 3, a limiting rail 4 installed inside each of the two first limiting frames 41, an air-raid shelter door 5 slidably connected inside the limiting rail 4, an air-raid shelter door 51 equidistantly distributed inside the air-raid shelter door 5, and an air-raid shelter door 51 equidistantly distributed inside the limiting rail 4 installed at the bottom of the air-raid shelter door 5. The movable roller 52 is limited by the limiting slide rail 4; a second limiting frame 43 is installed on the top of the fixed base plate 1 and on the outside of the security door 5. The second limiting frame 43 is located between two first limiting frames 41. The two first limiting frames 41 are installed inside and on both sides of the security door 5. The top of each of the mounting clamps 48 is equipped with a limiting roller 49 for use with the security door 5. The second limiting frame 43 is equipped with mounting clamps 48 and limiting rollers 49 of the same structure. The limiting rollers 49 limit the sliding trajectory of the security door 5.

[0032] In this solution, a mounting bracket 23 is installed on the top of the first security wall 2, and a surveillance camera 27 is installed inside the mounting bracket 23;

[0033] In this design, a limiting mechanism is installed on the side of the security door 5 away from the second security wall 3. This limiting mechanism includes a positioning frame 6. A mounting frame 61 is installed on the side of the security door 5 away from the second security wall 3. The positioning frame 6 is installed on one side of the mounting frame 61.

A fixing block 62 is fixedly connected to one end of the connecting rod 66. One side of the fixing block 62 is fixedly connected to the security door 5. The positioning frame 6... The device is slidably connected to a movable slide plate 64. One side of the movable slide plate 64 is connected to a movable slider 63. The outer side of the movable slider 63 is threaded with a third positioning bolt 691 that matches the positioning of the mounting sleeve plate 65. The third positioning bolt 691 positions and installs the mounting sleeve plate 65 and the movable slider 63, ensuring that when the security door 5 slides, it will drive the fixed block 62 to slide to one side. With the connection of the connecting rod 66, the movable slider 63 will slide outside the mounting frame 61, the limit roller 67 will roll on one side of the mounting frame 61, and the movable slide plate 64 will slide inside the positioning frame 6. Through multiple sliding, the device has a buffering effect when the security door 5 slides, and at the same time, it is convenient for subsequent normal reset. The overall structure does not use a lot of electrical equipment, saving the overall use and installation costs.

[0034] Going a step further, such as Figures 1-6 As shown: In this solution, the top of the positioning frame 6 and the side away from the moving slide plate 64 are provided with equally spaced mounting slots 69. The inside of each mounting slot 69 is threaded with a second positioning bolt 68 extending into the inside of the fixed base plate 1. The positioning frame 6 and the fixed base plate 1 are positioned and installed by multiple second positioning bolts 68, which improves the stability of the limiting roller 67 when it moves. The second positioning bolts 68 can be screwed all the way into the mounting slot 69 during installation, which avoids collision when the moving slide plate 64 moves and extends the service life of the equipment.

[0035] Going a step further, such as Figure 4As shown: In this scheme, the bottom of the first limiting frame 41 is equipped with symmetrically distributed first mounting base plates 42, and the first mounting base plates 42 are all connected to the top of the fixed base plate 1. The bottom of the second limiting frame 43 is fixedly connected with symmetrically distributed second mounting base plates 44, and the second mounting base plates 44 are all connected to the top of the fixed base plate 1. The second mounting base plates 44 provide auxiliary support for the second limiting frame 43 as a whole, and the first mounting base plates 42 provide auxiliary support for the first limiting frame 41 as a whole.

[0036] Going a step further, such as Figures 1-6 As shown, in this scheme, the top of the first security wall 2 is fixedly connected to a battery storage compartment 21, which is located on the side away from the mounting frame 23. A lighting lamp 22 is fixedly connected to the top of the battery storage compartment 21. The top of the second security wall 3 is equipped with a battery storage compartment 21 and a lighting lamp 22 of the same structure. Both battery storage compartments 21 are equipped with batteries. The battery storage compartments 21 and batteries work together to supply power to the overall power equipment. The lighting lamp 22 provides auxiliary lighting to facilitate nighttime operations.

[0037] In this scheme, a fixing rod 45 is installed inside the second limiting frame 43. A counterweight 46 is fixedly connected to the top of the fixing rod 45. A wireless signal transceiver 47 is installed on the top of the counterweight 46. A main control board is installed inside the wireless signal transceiver 47. A control chip is fixedly connected to the outside of the main control board. The battery compartment 21, the lighting lamp 22, the monitoring camera 27 and the wireless signal transceiver 47 are all electrically connected to the control chip. The control chip is used to control the operation of the battery compartment 21, the lighting lamp 22, the monitoring camera 27 and the wireless signal transceiver 47, realizing unified management of power equipment.

[0038] Going a step further, such as Figures 1-2 , Figure 6 As shown, in this scheme, a positioning side plate 24 is fixedly connected to one side of each of the two mounting brackets 23. The positioning side plate 24 is located on one side of the first security wall 2. The outer side of the positioning side plate 24 is threaded with a first positioning bolt 25 extending into the interior of the first security wall 2. The positioning side plate 24 and the first security wall 2 are positioned and installed by the first positioning bolt 25, thereby achieving the installation effect of the mounting bracket 23 and the first security wall 2. The top of the second security wall 3 is equipped with a mounting bracket 23 of the same structure and a monitoring camera 27.

[0039] In this solution, both mounting brackets 23 are fixedly connected to the inside of the connecting plate 26. One side of each connecting plate 26 is fixedly connected to the positioning side plate 24, and the other side of each connecting plate 26 is connected to the monitoring camera 27.

The installation position of the monitoring camera 27 is limited by the connecting plate 26, which facilitates the adjustment of the monitoring position during use.

[0040] Working principle:

[0041] like Figures 1-6 As shown:

[0042] By setting up a fixed base plate 1, a first security wall 2, a second security wall 3, and a limiting mechanism, both energy storage compartments 21 are equipped with batteries during use. The energy storage compartments 21 and batteries work together with the power supply of the overall power equipment, and the lighting 22 provides auxiliary lighting to facilitate nighttime operations.

[0043] The control chip is used to control the operation of the energy storage compartment 21, the lighting 22, the monitoring camera 27 and the wireless signal transceiver 47, realizing unified management of power equipment.

[0044] The security door 5 is manually pulled, and it slides towards the second security wall 3 within the limiting slide rail 4 until a space for entry and exit is left between the first security wall 2 and the second security wall 3. To facilitate pulling the security door 5, a handle can be installed on one side of the security door 5, making the pulling process easier and saving the installation and use costs of the equipment. At the same time, to ensure the stability of the security door 5 when it is normally closed, corresponding set screws can be installed on the outside of the two first limiting frames 41 to help the security door 5 to be positioned.

[0045] The second limiting frame 43 has an installation clamp 48 and a limiting roller 49 with the same structure installed inside. The limiting roller 49 limits the sliding trajectory of the security door 5. The third positioning bolt 691 positions and installs the installation sleeve 65 and the movable slider 63, ensuring that when the security door 5 slides, it will drive the fixed block 62 to slide to one side. With the connection of the connecting rod 66, the movable slider 63 will slide outside the installation frame 61, the limiting roller 67 will roll on one side of the installation frame 61, and the movable slide plate 64 will slide inside the positioning frame 6. Through multiple sliding, the device has a buffering effect when the security door 5 slides, and at the same time, it is convenient for subsequent normal reset. The overall structure does not use a lot of electrical equipment, saving the overall use and installation costs.

[0046] The positioning frame 6 and the fixed base plate 1 are positioned and installed by multiple second positioning bolts 68, which improves the stability of the limit roller 67 when it moves. The second positioning bolts 68 can be tightened all the way into the mounting groove 69 during installation, which avoids collision when the moving slide plate 64 moves and extends the service life of the equipment.

[0047] The second mounting base plate 44 provides auxiliary support for the second limiting frame 43 as a whole, the first mounting base plate 42 provides auxiliary support for the first limiting frame 41 as a whole, and the first positioning bolt 25 positions and installs the positioning side plate 24 and the first security wall 2, thereby achieving the installation effect of the mounting frame 23 and the first security wall 2.

[0048] The top of the second security wall 3 is equipped with a mounting bracket 23 and a monitoring camera 27 of the same structure. The installation position of the monitoring camera 27 is limited by the connecting plate 26, which facilitates the adjustment of the monitoring position during use. It realizes normal security while facilitating remote monitoring of the site. Through multiple limit sliding, it avoids the safety hazards caused by excessive speed during sliding, and also facilitates normal reset afterward.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
