Description

Technical Field

[0001] The utility model belongs to the technical field of civil air defense call, in particular to a call button for civil air defense projects. Background Art

[0002] Civil air defense projects are underground structures used for air defense during wartime. The call button is installed on the outside of the air defense sealed door, with the bottom edge 1.4 meters from the ground. It is used to call the on-duty personnel inside the civil air defense project and open the sealed door to enter the civil air defense project. Therefore, although small, the call button serves as a vital link between internal and external communication within the civil air defense project.

[0003] The prior art discloses a civil air defense call button, with publication number CN204360936U, application date 2015-01-26, and publication date 2015-05-27. The button comprises a turntable, a first lining plate, a second lining plate, a button, a button holder, and a button compartment, all connected in sequence. The sidewall of the button compartment has a wiring port. Rotating the turntable exposes a through-hole in the second lining plate, allowing a finger to be inserted into the button compartment to press the button. The button compartment also includes several steel bar fasteners, which secure the compartment to steel bars in the wall via mounting holes in the base of the compartment. However, the button can only be pressed after the turntable is rotated a certain angle to fully align the through-hole on the turntable with the through-hole on the second lining plate. However, in dimly lit environments, it is difficult to clearly see whether the two through-holes are fully aligned, requiring considerable time to align the two holes. This impacts response time and delays operational opportunities. Utility Model Content

[0004] The purpose of the utility model is to provide a call button for civil air defense projects, which does not require time and effort to align the through holes on the turntable and the through holes on the second lining plate, is easy to operate, and ensures timely response.

[0005] The purpose of the present utility model is achieved as follows: a call button for civil air defense projects, comprising a first lining plate, a turntable, a second lining plate, a button and a button seat arranged in sequence from the outside to the inside, a first through hole is provided on the turntable and is rotatably arranged on the second lining plate, a second through hole is provided on the second lining plate corresponding to the button, a weight block is provided on the inward side of the turntable, and limiting grooves are provided at both ends of the second lining plate corresponding to the weight block, and when the end face of the weight block abuts against any limiting groove, the first through hole overlaps with the second through hole.

[0006] In a natural state, under the action of the gravity of the weight block, the first through hole will deviate from the second through hole around the center of the turntable until the weight block is at the lowest point and the turntable is in a balanced state. At this time, the button is completely hidden behind the turntable. The turntable is manually rotated until the end face of the weight block abuts against any limit slot, and the first through hole overlaps with the second through hole, thereby exposing the button, making it convenient for the on-duty personnel to press the button. Compared with the prior art, the beneficial effect of the utility model is that the design of the limit slot and the weight block is used to limit the maximum rotation angle of the turntable. There is no need to manually align the first through hole and the second through hole. The turntable only needs to be rotated until the weight block abuts against the limit slot to expose the button. The operation is quick and convenient, and the response time is guaranteed.

[0007] As a further improvement of the present invention, the load-bearing block is a left-right symmetrical arc-shaped structure, the left and right end faces are both arc-shaped surfaces, and the limiting groove is an arc-shaped structure adapted to the arc-shaped surface.

[0008] As a further improvement of the present invention, the number of the first through holes is two, and the two first through holes are symmetrically distributed on the turntable.

[0009] As a further improvement of the present invention, a rotating handle is provided on the outward side of the turntable.

[0010] As a further improvement of the present invention, the height of the rotating handle is not greater than the thickness of the first lining plate.

[0011] As a further improvement of the present invention, the turntable is rotatably arranged on the front side of the second lining plate through a rotating shaft.

[0012] As a further improvement of the present invention, an operation window is provided on the first lining plate, and the first through hole and the rotating handle are always located within the exposed range of the operation window.

[0013] As a further improvement of the present invention, the operating window is a circular structure.

[0014] As a further improvement of the present invention, the first lining plate is provided with first mounting holes at four corners, the second lining plate is provided with second mounting holes corresponding to the first mounting holes, and the button seat is provided with a third mounting hole corresponding to the first mounting hole.
