Description

Technical Field

[0001] This utility model relates to the field of shielding door technology, specifically a non-standard modular shielding door structure. Background Technology

[0002] The use of microwave weapons and electromagnetic interference technology on the battlefield can, at best, disrupt enemy communications, paralyze command, disable weapons, and render personnel incapable of working; at worst, it can detonate enemy weapons and cause mass casualties. For every spear, there must be a shield. To counter microwave weapons and electromagnetic interference, the research and development of military electromagnetically shielded bunkers with electromagnetic shielding capabilities has attracted significant attention to meet the needs of modern warfare.

[0003] When designing, fabricating, and assembling electromagnetic shielding cabins, the electrical continuity of each component must be considered. The cabin door is a crucial structural element; as the largest opening in the shielded cabin, its electromagnetic shielding performance directly determines the overall shielding performance of the cabin. Generally, the smaller the gap between the door panel and the door frame, the higher the shielding performance. Traditionally, planar shielding doors are commonly used, and the fit between a planar shielding door and its frame is easy to achieve. However, fitting irregularly shaped shielding doors and their frames is not so easy. Therefore, a special shielding door structure for irregularly shaped cabins is proposed to address the specific requirements of these cabins. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a special-shaped modular shelter shielding door structure that can meet the special installation requirements of modular shelters. An additional two-pronged lock is installed at the corner of the door panel to strengthen the fit between the door panel and the door frame at the corner, reduce gaps, and achieve the shielding function. By adding an outer protective plate and an inner protective plate at the corner of the door panel, the structural strength at the corner of the door panel is increased, and deformation at this point is prevented from weakening the shielding effect, thus ensuring the shielding effectiveness of the modular shelter door. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-standard modular shelter shielding door structure, including a door frame and a door panel, wherein the door panel is hinged to the door frame, and both the door frame and the door panel have an included angle; the side of the door panel facing the cabin is provided with a two-pronged lock and a three-pronged lock, the two-pronged lock is near the corner and is correspondingly inserted and engaged with the two opposite sides of the door frame, the three-pronged lock is near the lower part of the door frame and is correspondingly inserted and engaged with the two opposite sides and the lower side of the door frame; two gas springs are also provided between the door frame and the door panel, the gas springs are located inside the cabin, and both ends of the gas springs are respectively connected to the door frame and the door panel through gas spring support seats.

[0006] Preferably, the joint between the door frame and the door panel is provided with a waterproof strip and two shielding pads.

[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a non-standard modular shelter shielding door structure, including a door frame 2 and a door panel 3. The door panel 3 is hinged to the door frame 2 by a hinge 1. Both the door frame 2 and the door panel 3 have an included angle. The side of the door panel 3 facing the cabin is provided with a two-pronged lock 8 and a three-pronged lock 10. The two-pronged lock 8 is close to the corner and is correspondingly inserted and engaged with the two opposite sides of the door frame 2. The three-pronged lock 10 is close to the lower part of the door frame 2 and is correspondingly inserted and engaged with the two opposite sides and the lower side of the door frame 2.

[0019] The gap between the door frame 2 and the door panel 3 is the main factor affecting the electromagnetic shielding effectiveness of the cabin door. Considering that it is not easy to achieve a tight fit between the irregular door frame 2 and the door panel 3 at the corner, a set of two-pronged locks 8 is set at the corner to strengthen the fit between the door panel 3 and the door frame 2 at the corner, reduce the gap, achieve the shielding function, and meet the requirements of the irregular shielding door of the cabin.

[0020] It should be noted that two gas springs 6 are also installed between the door frame 2 and the door panel 3. The gas springs 6 are located inside the compartment, and both ends of the gas springs 6 are connected to the door frame 2 and the door panel 3 respectively through the gas spring support 5. When the door panel 3 is opened using the gas springs 6, it can be suspended at any angle for easy use.

[0021] Furthermore, a waterproof strip 11 and two shielding pads 12 are provided at the joint between the door frame 2 and the door panel 3. The waterproof strip 11 and the shielding pads 12 are installed on the edge of the door frame 2, and the shielding pads 12 are installed on the edge of the door panel 3. The door panel 3 has protrusions that correspond to and abut against the waterproof strip 11. The shielding pads 12 of the door frame 2 and the shielding pads 12 of the door panel 3 are in partial contact. The door panel 2 and the door frame 3 are reliably connected through the shielding pads 12 to achieve electrical continuity between the door and the cabin panel, thereby achieving the shielding effectiveness of the cabin door.

[0022] Furthermore, the door panel 3 is provided with an inner protective plate 9 and an outer protective plate 4 on the inner and outer sides of the corner. The inner protective plate 9 and the outer protective plate 4 are fitted to the corner of the door panel 3. Both the inner protective plate 9 and the outer protective plate 4 are aluminum profile sheet metal parts. The inner protective plate 9 and the outer protective plate 4 are riveted to the door panel 3. The door and door are frequently used, and the corner is prone to deformation. The gap between the door frame 2 and the door panel 3 will gradually increase, which will greatly weaken the shielding effect of the cabin. Therefore, the inner protective plate 9 and the outer protective plate 4 are added at the corner of the door panel 3 to strengthen the structure of the door panel 3.

[0023] Furthermore, handles 7 are provided on both sides of the door panel 3 facing the cabin, making it easy to push and pull the door panel 3;

[0024] In addition, hinge 1 is located at the top of door frame 2, and there are two hinges 1.
