Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a civil air defense door with an anti-collision structure. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. Doors, as a safety protection barrier, are often used to block the connectivity of different areas with various protection requirements.

[0003] For example, an anti-collision door disclosed in publication number CN216641885U forms a gap between the anti-collision plate and the door panel at the arched part, and the gap near the middle of the door is the largest, which provides a reliable buffering area for buffering collision.

[0004] However, the anti-collision device has certain limitations during use. Since the main structure of the door adopts an integral structure, the interior of the door body is solid, and there is no reserved gap for shock absorption and buffering. When the door is hit, it cannot effectively buffer the impact force, which can easily cause damage to the door and reduce the anti-collision effect of the door, and cannot meet the use requirements. In view of this, we propose a civil defense door with an anti-collision structure. Utility Model Content

[0005] The purpose of the utility model is to provide a human defense door with an anti-collision structure to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a civil air defense door with an anti-collision structure, comprising a civil air defense door body, the side wall of the civil air defense door body is provided with an anti-collision structure, and the anti-collision structure comprises:

[0007] A buffer groove is provided inside the civil air defense door body, one end of a first buffer spring is fixedly installed on four sides of the inner wall of the buffer groove, the other end of the first buffer spring is elastically connected to a slider, a connecting rod is hinged on the side wall of the slider, and a sliding plate is fixedly installed on the upper end of the connecting rod;

[0008] The two groups of sliding rods are respectively fixedly mounted on both sides of the side walls of the sliding plate, one end of the sliding rod away from the sliding plate penetrates the civil air defense door body and is fixedly mounted with an anti-collision plate, and a second buffer spring is arranged on the surface of the sliding rod;

[0009] A protective structure is provided on the side wall of the impact plate.

[0010] Preferably, the protection structure includes a protection airbag fixedly mounted on the side wall of the anti-collision plate, an air storage airbag fixedly mounted on the inner wall of the buffer groove, one end of a ventilation hose is provided on both sides of the upper end of the air storage airbag, and the other end of the ventilation hose is connected to the side wall of the protection airbag.

[0011] Preferably, one end of the second buffer spring is fixedly connected to the side wall of the civil defense door body, and the other end of the second buffer spring is fixedly connected to the side wall of the anti-collision plate.

[0012] Preferably, friction pads are fixedly mounted on both sides of the inner wall of the buffer groove, and two groups of side walls of the friction pads are in contact with both sides of the sliding plate respectively.

[0013] Preferably, sealing rings are provided at the connections between the civil air defense door body, the sliding rod and the ventilation hose.

[0014] Preferably, the protection airbag is filled with one third of the gas volume, and the air storage airbag is in a state of sufficient gas.

[0015] Compared with the prior art, the utility model provides a human air defense door with an anti-collision structure, which has the following beneficial effects:

[0016] 1. The civil air defense door with an anti-collision structure is conveniently designed to improve the practicality of the civil air defense door body by setting up an anti-collision structure. When the surface of the civil air defense door body is about to be impacted, it will first hit the anti-collision plate on its surface. At this time, the anti-collision plate can move inward by squeezing two sets of sliding rods and the second buffer springs, and at the same time squeeze the two sets of first buffer springs to displace the two sets of first buffer springs and provide buffering capacity, thereby reducing the impact force and avoiding damage to the civil air defense door body by impact.

[0017] 2. The civil air defense door with anti-collision structure is conveniently provided with a protective structure to provide certain protection to the colliding objects. When the anti-collision plate moves due to impact, the sliding plate moves inward to squeeze the air storage airbag. At this time, the gas stored in the air storage airbag enters the protective airbag through the ventilation hose, so that the protective airbag quickly inflates to provide certain protection to the colliding objects.

[0024] Specifically, the anti-collision structure 2 of the technical solution of the utility model includes: a buffer groove 21, a first buffer spring 22, a slider 23, a connecting rod 24, a sliding plate 25, a sliding rod 26, an anti-collision plate 27, and a second buffer spring 28.

[0025] In one embodiment of the utility model, a buffer groove 21 is opened inside the civil defense door body 1, and one end of a first buffer spring 22 is fixedly installed on all four sides of the inner wall of the buffer groove 21, and the other end of the first buffer spring 22 is elastically connected to a slider 23. A connecting rod 24 is hinged on the side wall of the slider 23, and a sliding plate 25 is fixedly installed on the upper end of the connecting rod 24. Two groups of sliding rods 26 are fixedly installed on both sides of the side walls of the sliding plate 25. One end of the sliding rod 26 away from the sliding plate 25 passes through the civil defense door body 1 and is fixedly installed with an anti-collision plate 27. A second buffer spring 28 is arranged on the surface of the sliding rod 26. By setting the anti-collision structure 2, it is convenient to improve the practicality of the civil defense door body 1. When the surface of the civil defense door body 1 is about to be impacted, the anti-collision of its surface will be firstly performed. The plate 27 collides with the anti-collision plate 27, and at this time, the anti-collision plate 27 moves inwardly under the impact to squeeze the two groups of sliding rods 26. At this time, the sliding rods 26 move inwardly and compress the second buffer springs 28 on their surface, and the sliding rods 26 move to drive the sliding plate 25 of its side wall to move. The movement of the sliding plate 25 drives the connecting rod 24 of its side wall to move, thereby squeezing the slider 23 and the first buffer spring 22 hinged to the connecting rod 24, so that the two groups of first buffer springs 22 are displaced and provide buffering capacity, and the sliding plate 25 moves inwardly to rub on the surface of the friction pad 4, thereby reducing the impact force, thereby preventing the civil defense door body 1 from being damaged by impact, and a protective structure 3 is provided on the side wall of the anti-collision plate 27.

[0026] Please continue reading Figure 1-Figure 4 The protective structure 3 includes a protective airbag 31 fixedly mounted on the side wall of the anti-collision plate 27, and an air storage airbag 32 is fixedly mounted on the inner wall of the buffer groove 21. Both sides of the upper end of the air storage airbag 32 are provided with one end of a ventilation hose 33, and the other end of the ventilation hose 33 is connected to the side wall of the protective airbag 31. By setting up the protective structure 3, it is convenient to provide a certain protection for the impacted object. When the anti-collision plate 27 is impacted and moved, the sliding plate 25 will squeeze the air storage airbag 32 on the inner wall of the buffer groove 21 when it moves inward. At this time, the gas stored in the air storage airbag 32 enters through the ventilation hose 33. The airbag 31 is filled with one third of the gas, and the air storage bag 32 is filled with sufficient gas.

[0027] When the surface of the civil defense door body 1 is about to be impacted, it will first hit the anti-collision plate 27 on its surface. At this time, the anti-collision plate 27 will move inwards under the impact to squeeze the two groups of sliding rods 26. At this time, the sliding rod 26 moves inwards and compresses the second buffer spring 28 on its surface. The movement of the sliding rod 26 drives the sliding plate 25 of its side wall to move. The movement of the sliding plate 25 drives the connecting rod 24 of its side wall to move, thereby squeezing the slider 23 and the first buffer spring 22 hinged to the connecting rod 24, so that the two groups of first buffer springs 22 are displaced and provide buffering capacity, and the sliding plate 25 moves inwards to rub on the surface of the friction pad 4, thereby reducing the impact force, and the sliding plate 25 moves inwards to squeeze the air storage bag 32 on the inner wall of the buffer groove 21. At this time, the gas stored in the air storage bag 32 enters the protective air bag 31 through the ventilation hose 33, so that the protective air bag 31 quickly swells to provide a certain protection for the impacted object, thereby improving the practicality of the device.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
