Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, and more specifically, to a quick-locking civil air defense door. 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.

[0003] When opening the current civil air defense door, it is necessary to rotate the wheel several times before the door body and the door frame can be locked. The function is relatively slow and not fast enough. Therefore, in order to solve the above problem, a quick locking civil air defense door is specially proposed. Utility Model Content

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides a quick-locking civil defense door, including a door frame and a civil defense door body, one side of the door frame is hinged to the civil defense door body, a slide groove is provided on the civil defense door body, a limit plate is fixedly connected in the slide groove, a circular hole is provided on the limit plate, a fixed rod is slidably connected in the circular hole, a spring is sleeved on the fixed rod, one end of the spring is fixedly connected to a sliding block, the sliding block is provided with an arc groove, a rotating plate is slidably connected in the slide groove, a rotating plate is integrally connected to the rotating plate, a bearing is embedded in the civil defense door body, the rotating rod is movably inserted into the bearing, a through hole is provided on the civil defense door body, one end of the fixed rod is inserted in the through hole.

[0008] When using a quick-locking civil defense door of the present technical solution, through the joint action of the spring, limit plate, rotating plate, rotating rod and fixing hole, the fixing rod can be stuck into the fixing hole by twisting the rotating plate, so that the civil defense door can be quickly fixed to the door frame, thereby achieving the effect of quickly locking the door.

[0009] Furthermore, one end of the rotating rod is fixedly connected with a rotating wheel.

[0010] Furthermore, fixing holes are symmetrically provided at the upper and lower ends of the door frame.

[0011] Furthermore, an indicator arrow is integrally connected to the civil air defense door, and the indicator arrow is located near the rotating wheel.

[0012] Furthermore, the sliding block is slidably connected in the sliding groove, and there are two sliding blocks, and the rotating plate is located between the two sliding blocks.

[0013] (III) Beneficial effects

[0014] In summary, the utility model has the following beneficial effects:

[0015] Under the joint action of the spring, limit plate, rotating plate, rotating rod and fixed hole, the rotating plate is turned. When the rotating plate is rotated to 90°, the spring is compressed, and the sliding block slides in the slide groove, moving with the fixed rod, so that the fixed rod can be stuck in the fixed hole, quickly fixing the civil air defense door to the door frame, thereby achieving the effect of quickly locking the door.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0023] Example:

[0024] The following is combined with Figure 1—3 The utility model is further described in detail.

[0025] See also Figure 1-3 The utility model provides a technical solution: a quick-locking civil defense door, including a door frame 2 and a civil defense door body 3. The upper and lower ends of the door frame 2 are symmetrically provided with fixing holes 1. One side of the door frame 2 is hinged with the civil defense door body 3.
