As shown in fig. 1-5, the embodiment of the application discloses a building civil air defense foundation pit support structure, which comprises a limit seat 1, a slide bar 12, a protection frame 2, a protection net 21, a slide block 3, a first spring 31, a driving assembly 4, a limit rod 5, a first magnet block 6, a second magnet block 61 and a second spring 7. The limiting seat 1 is of a rectangular rod-shaped structure, and sliding grooves 11 are formed in two opposite side walls of the limiting seat 1. The slide bar 12 is of a rectangular rod-shaped structure, and the slide bar 12 is arranged in the slide groove 11 in a sliding way. The protection frame 2 is a platy structure with a square annular cross section, and the side walls of the protection frame 2 and the two slide bars 12, which are close to each other, are mutually fixed. The protection net 21 is disposed on the inner wall of the protection frame 2 for improving the protection effect of the protection frame 2. Two mutually symmetrical clamping grooves 22 are formed in two opposite inner walls of the sliding groove 11, sliding grooves 23 corresponding to the clamping grooves 22 one by one are formed in two opposite side walls of the sliding rod 12, the sliding block 3 is of a rectangular block structure, and the sliding block 3 is arranged in the sliding grooves 23 in a sliding mode. One end of the first spring 31 is fixed on the side wall of the slider 3 away from the clamping groove 22, and the other end of the first spring 31 is fixed on the inner wall of the sliding groove 23.

The upper surface of slide bar 12 has offered the rotation groove 32, and drive assembly 4 sets up on slide bar 12 for four sliders 3 of simultaneous drive, drive assembly 4 include dwang 41 and fixed rope 42. The rotating lever 41 has a circular lever-like structure, and the rotating lever 41 is rotatably provided in the rotating groove 32. The four fixing ropes 42 are provided, one ends of the fixing ropes 42 are fixed on the side wall of the rotating rod 41, and the other ends of the four fixing ropes 42 are respectively fixed on the side walls of the four sliding blocks 3 away from the clamping grooves 22.

When the staff needs to dismantle the protection frame 2, the staff only needs to rotate the rotating rod 41, so that four fixed ropes 42 can be wound on the rotating rod 41 simultaneously, and then the four sliding blocks 3 can move towards the direction close to the axis of the rotating rod 41 under the action of the four fixed ropes 42, so that the sliding blocks 3 are separated from the clamping grooves 22, at the moment, the staff only needs to slide the sliding rod 12 upwards to enable the sliding rod 12 to be separated from the sliding groove 11, and the operation difficulty of the staff is reduced.

The limiting rod 5 is of a rectangular rod-shaped structure, the limiting rod 5 is fixed on the bottom surface of the rotating rod 41, and a limiting groove 51 matched with the limiting rod 5 is formed in the inner bottom wall of the rotating groove 32.

After the staff makes slider 3 and draw-in groove 22 mutually separate through dwang 41, the staff only need downwardly sliding dwang 41, can make gag lever post 5 and spacing groove 51 interconnect, and then makes spacing groove 51 carry out spacingly to dwang 41 to make dwang 41 keep stable, need not the staff and continuously exert the effort that makes it keep stable to dwang 41, and then reduced the operation degree of difficulty of staff.

In order to reduce the difficulty of the operation of the staff, the bottom surface of the slide 3 is provided with an inclined surface 52 on the edge intersecting with the side wall thereof remote from the slide rod 12. When the staff needs to make the slide bar 12 and the slide groove 11 interconnect, the staff only needs to make the slide groove 11 and the slide bar 12 right opposite to each other and slide the slide bar 12 downwards, so that the slide bar 12 can be abutted against the inclined surface 52, and the staff is not required to start the driving assembly 4 in advance, thereby reducing the operation difficulty of the staff.

The first magnet block 6 is of a rectangular block structure, and the first magnet block 6 is embedded in the bottom surface of the sliding block 3. The second magnet 61 has a rectangular block-like structure, and the second magnet 61 is fitted to the inner bottom wall of the slide groove 23.

When the worker needs to install the protection frame 2, the worker needs to slide the slider 3 in a direction approaching to the axis of the rotation lever 41, so that the first magnet block 6 and the second magnet block 61 are attracted to each other, and the slider 3 is kept stable, and at this time, the part of the slider 3 where the inclined surface 52 is not opened is completely located in the sliding groove 23. Subsequently, when the worker slides down the slide bar 12, the slide bar 12 abuts against the inclined surface 52, and the slide block 3 is further slid in a direction approaching the axis of the rotating rod 41, in which process the first spring 31 is further compressed. Subsequently, when the sliding block 3 is aligned with the clamping groove 22, the sliding block 3 is quickly reset and moves into the clamping groove 22 under the action of the first spring 31, and at this time, part of the upper surface of the sliding block 3 abuts against the inner top wall of the clamping groove 22, so that the limiting effect of the sliding block 3 on the sliding rod 12 is improved.

One end of the second spring 7 is fixed to the inner bottom wall of the rotation groove 32, and the upper end of the second spring 7 abuts against the bottom surface of the rotation lever 41. When the staff needs to make gag lever post 5 and spacing groove 51 mutually separate, the staff only need to press down dwang 41, can make second spring 7 continuously compressed, and at this moment, the staff only need loosen dwang 41, can make dwang 41 upwards move under the effect of second spring 7, and then makes gag lever post 5 and spacing groove 51 mutually separate to the operation degree of difficulty of staff has been reduced.

In order to improve the stability of the device, the inner wall of the rotary groove 32 is provided with a receiving groove 8 for receiving the fixing rope 42.

In order to reduce the difficulty of the worker to rotate the rotating rod 41, the upper end of the rotating rod 41 is provided with a groove 9.
