Technical Field

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

[0002] Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are classified in a relatively clear manner, 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, etc. In order to improve the safety performance of the teaching environment, they are often used in educational parks.

[0003] However, in the existing technology, air defense doors are mainly civil defense protection equipment proposed to prevent and mitigate the harm of disasters. However, some air defense doors cannot be opened normally when encountering sudden or unexpected situations (such as fire or rust on internal parts), which may pose certain safety hazards. Therefore, it is necessary to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, civil defense doors are mainly civil defense protection equipment proposed to prevent and mitigate the harm of disasters. However, some civil defense doors cannot be opened normally when encountering sudden or unexpected situations (such as fire or rust on internal parts), which may pose certain safety hazards.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a civil defense door structure, comprising: a door frame; a door body, with hinges disposed inside the door frame; and further comprising:

[0006] The buckle box is installed inside the door frame via a mounting shaft bearing, and a positioning hole is provided on one side surface of the buckle box;

[0007] A limiting groove is formed inside the door frame. A limiting post is slidably embedded inside the limiting groove. An inclined groove is formed on the surface of the limiting post. A positioning post is provided on one side surface of the limiting post. One end of the positioning post is movably embedded inside the positioning hole.

[0008] Limiting groove two is formed inside the door frame. A pressing block is slidably embedded inside the limiting groove two. A push rod is provided at one end of the pressing block. A round shaft is provided on the surface of the push rod. The round shaft is slidably embedded inside the positioning post. One end of the push rod is connected to the inner wall of limiting groove one by a spring.

[0009] Preferably, a pressing plate is installed inside the door body via a mounting shaft bearing, and a spring is provided on one side surface of the pressing plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the door provides a limiting function for the pressing plate, while the pressing plate fixes the second spring.

[0011] Preferably, one end of the second spring is disposed on the inner wall of the door body, and the door body has an inner cavity.

[0012] The technical effect of adopting the above-mentioned further solution is that the spring is connected to the inner wall of the door to provide a reset function for the pressing plate, and at the same time, the inner cavity of the door facilitates the installation of parts.

[0013] Preferably, a locking tongue is slidably embedded inside the inner cavity, and a connecting rope is provided on one end surface of the locking tongue.

[0014] The technical effect of adopting the above-mentioned further solution is that the locking tongue is limited by the inner cavity, which makes it convenient for one end of the locking tongue to be embedded in the inside of the buckle box for locking, and at the same time provides a connection for the connecting rope, which facilitates movement.

[0015] Preferably, one end of the connecting rope is disposed on the surface of the pressing plate, and a spring is disposed symmetrically on one side of the locking tongue.

[0016] The technical effect of adopting the above-mentioned further solution is that when the pressing plate moves, the connecting rope drives the second spring to move, thereby performing the opening and closing work, while the locking tongue provides a fixing function for the third spring.

[0017] Preferably, one end of each of the two springs is disposed on the inner wall of the inner cavity, and a handle is movably disposed on the surface of the door.

[0018] The technical effect of adopting the above-mentioned further solution is that: one end of the spring is connected to the inner wall of the inner cavity, which facilitates the reset of the lock tongue, and the door surface is provided with a handle for easy opening and closing.

[0019] Preferably, the inner wall of the handle is provided with a connector, which is movably sleeved on the surface of the connecting rope.

[0020] The technical effect of adopting the above-mentioned further solution is that when the handle is rotated, the connecting part is driven to rotate around the handle as a fixed point, which drives the internally embedded connecting rope to move, so that the locking tongue moves and performs the opening and closing work.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, by pressing the pressing block and moving it along the inside of the limiting groove two, the round shaft on the surface of the push rod moves along the inside of the inclined groove, causing the positioning post on the surface of the limiting post to disengage from the inside of the buckle box, thereby directly pushing the buckle box so that the buckle box contacts the inclined part on the surface of the locking tongue. This also allows for quick control of the opening and closing operation. The spring one provides a reset function for easy repeatable operation, thereby improving the versatility of the opening and closing of the equipment and avoiding the situation where the equipment cannot be opened and closed quickly due to a problem with a single part.

[0023] 2. In this utility model, rotating the handle causes the connecting piece to rotate around the handle as a fixed point, which in turn moves the internally embedded connecting rope, causing the locking tongue to move along the inside of the cavity, thereby disengaging from the inside of the snap box and enabling opening and closing. The two ends of the spring are respectively connected to the surface of the locking tongue and the inner cavity, facilitating the reset operation. In addition, pressing the pressing plate causes the pressing plate to move around the mounting shaft as the center, which in turn moves the locking tongue away from the inside of the snap box via the connecting rope, enabling opening and closing. The opening and closing are controlled in multiple ways, and the operation is simple. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] Example 1, as Figure 1-4 As shown, this utility model provides a structure for a civil defense door, including: a door frame 1; a door body 2, with hinges disposed inside the door frame 1; and further including: a latch box 101, which is disposed inside the door frame 1 via a mounting shaft bearing, with a positioning hole 1011 on one side surface of the latch box 101; a limiting groove 102, which is disposed inside the door frame 1, with a limiting post 1021 slidably embedded inside the limiting groove 102, and a slanted groove 1022 on the surface of the limiting post 1021, with a fixed groove 1022 on one side surface of the limiting post 1021. Positioning post 1023, one end of which is movably embedded inside positioning hole 1011; limiting groove 103, which is opened inside door frame 1, and pressing block 1031 is slidably embedded inside limiting groove 103. A push rod 1032 is provided at one end of pressing block 1031. A round shaft 1033 is provided on the surface of push rod 1032. The round shaft 1033 is slidably embedded inside positioning post 1023. One end of push rod 1032 is connected to the inner wall of limiting groove 102 by spring 1034.

[0033] In this embodiment, by pressing the pressing block 1031 and moving it along the inside of the limiting groove 103, the round shaft 1033 on the surface of the push rod 1032 moves along the inside of the inclined groove 1022, causing the positioning post 1023 on the surface of the limiting post 1021 to disengage from the inside of the buckle box 101, thereby directly pushing the buckle box 101, so that the buckle box 101 contacts the inclined part on the surface of the locking tongue 2021, which can also quickly control the opening and closing operation. With the spring 1034 providing reset for easy repeated operation, the versatility of the device's opening and closing is improved, and the inability to quickly open and close due to a problem with a single part is avoided.

[0034] In embodiment 2, a pressing plate 201 is installed inside the door body 2 via a mounting shaft bearing. A second spring 2011 is provided on one side surface of the pressing plate 201, and one end of the second spring 2011 is provided on the inner wall of the door body 2. An inner cavity 202 is opened inside the door body 2, and a locking tongue 2021 is slidably embedded inside the inner cavity 202. A connecting rope 2012 is provided on one end surface of the locking tongue 2021, and one end of the connecting rope 2012 is provided on the surface of the pressing plate 201. A third spring 2022 is provided symmetrically on one side surface of the locking tongue 2021, and one end of the two third springs 2022 is provided on the inner wall of the inner cavity 202. A handle 203 is movably provided on the surface of the door body 2, and a connector 2031 is provided on the inner wall of the handle 203. The connector 2031 is movably sleeved on the surface of the connecting rope 2012.

[0035] In this embodiment, rotating the handle 203 causes the connector 2031 to rotate around the handle 203, which in turn moves the internally embedded connecting rope 2012. This causes the locking tongue 2021 to move along the inside of the inner cavity 202, thereby disengaging from the inside of the buckle box 101 and opening / closing. The two ends of the spring 2022 are respectively connected to the surfaces of the locking tongue 2021 and the inner cavity 202, facilitating the reset process. Additionally, pressing the pressing plate 201 causes it to move around the mounting shaft, which in turn moves the locking tongue 2021 away from the inside of the buckle box 101 via the connecting rope 2012, allowing for opening / closing. The opening and closing are controlled in multiple ways, and the operation is simple.

[0036] Working principle: In use, rotating the handle 203 causes the connecting piece 2031 to rotate around the handle 203, moving the internally embedded connecting rope 2012. This causes the locking tongue 2021 to move along the inside of the inner cavity 202, thus disengaging from the inside of the latch box 101 for opening and closing. The two ends of the spring 2022 are respectively connected to the surfaces of the locking tongue 2021 and the inner cavity 202 for easy reset. Additionally, pressing the pressing plate 201 causes it to move around the mounting shaft, which, via the connecting rope 2012, moves the locking tongue 2021 away from the inside of the latch box 101, allowing for opening and closing. Multiple opening and closing methods are available, and the operation is simple. In addition, when a fault occurs inside the door body 2, pressing the pressing block 1031 moves it along the inside of the limiting groove 103, causing the round shaft 1033 on the surface of the push rod 1032 to move along the inside of the inclined groove 1022, causing the positioning post 1023 on the surface of the limiting post 1021 to disengage from the inside of the latch box 101, thereby directly pushing the latch box 101, so that the latch box 101 contacts the inclined part on the surface of the lock tongue 2021, which can also quickly control the opening and closing operation. With the spring 1034, a reset is provided to facilitate repeated operation, thereby improving the versatility of the device's opening and closing and avoiding the situation where the device cannot be opened and closed quickly due to a problem with a single part.

[0037] 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.
