Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model discloses a support device for a civil defense door, including a civil defense door body 1 and a sealing strip 2 disposed on the edge of the civil defense door body 1, and also includes a wall fixing component 3, a rotating component 4, a support component 5, a civil defense door locking component 6, and an auxiliary support component 7, wherein:

[0025] The wall fixing assembly 3 includes a fixing back plate 31, which is symmetrically fixed to the wall by bolts. A horizontal plate 32 is welded to one side of the fixing back plate 31.

[0026] Please refer to the appendix. Figure 2 The rotating component 4 includes a rotating shaft 41, with both ends of the rotating shaft 41 passing through the horizontal plate 32 and rotating in cooperation. A connecting rod 42 is welded onto the rotating shaft 41, with one end of the connecting rod 42 being fitted and limited in the rotating component 43 and rotating in cooperation. The rotating component 43 is fixed to the edge of the air defense door body 1 by screws. Specifically, the rotating component 43 fixed to the upper and lower parts of the edge of the air defense door body 1 is connected with the connecting rod 42, and together with the rotating shaft 41, it forms a preliminary positioning support for the air defense door body 1.

[0027] The auxiliary support component 7 includes an auxiliary plate 71, which is penetrated by a spiral shaft 72 and rotates in a spiral manner. The upper end of the spiral shaft 72 is connected to a knob 73, and the lower end is provided with a disc 74. The disc 74 is embedded in the bottom column 75 and slides in a sliding manner. The auxiliary plate 71 is welded to the bottom of the back of the air defense door body 1.

[0028] Please refer to the appendix. Figure 3 The support component 5 includes a support frame 51, which is fastened to the edge of the air defense door body 1 by bolts. A rotating shaft 41 passes through the support frame 51 and rotates in cooperation with it. The bottom surface of the support frame 51 abuts against a pad 52. A pad tube 53 is provided below the pad 52. The pad 52 and the pad tube 53 are welded to the rotating shaft 41. Specifically, the support frame 51 can share the pressure of the connecting rod 42. The pressure is transmitted to the fixed back plate 31 through the pad 52 and the pad tube 53.

[0029] In this embodiment, rotating the knob 73 drives the spiral shaft 72 to rotate in the auxiliary plate 71. The spiral shaft 72 and the auxiliary plate 71 move downward relative to each other through the spiral action, and then the disc 74 drives the bottom column 75 to abut against the ground to form support and horizontal friction. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 4 as well as Figure 5 A bearing 33 is fitted into the horizontal plate 32, and a pressure plate 34 is covered above the bearing 33. The pressure plate 34 is fastened to the horizontal plate 32 by screws. Specifically, the bearing 33 facilitates the rotation of the rotating shaft 41.

[0031] The rotating shaft 41 has support plates 35 at both ends, and the support plates 35 abut against the top surface of the inner ring of the bearing 33.

[0032] An L-shaped plate 36 is fixed to one side of the fixed back plate 31 located below by bolts. A limiting tube 37 is provided on the top surface of the L-shaped plate 36. The limiting tube 37 is fitted into the rotating shaft 41. Specifically, the L-shaped plate 36 supports the bottom end of the rotating shaft 41 to further strengthen the support function.

[0033] The air defense door locking assembly 6 includes a locking disc 61, which is fixedly connected to a rotating gear 62. The rotating gear 62 engages with a toothed plate 63 and meshes with it. One end of the toothed plate 63 is connected to a horizontal shaft 64.

[0034] The horizontal shaft 64 is fixedly connected to the transmission component 65. The transmission component 65 is fitted into the fixing component 66 and rotates with it. The fixing component 66 is fastened to the front of the air defense door body 1 by bolts. A locking shaft 67 is welded to one end of the transmission component 65. The locking shaft 67 passes through the stabilizing tube 68. The stabilizing tube 68 is symmetrically installed on the side of the air defense door body 1 by bolts.

[0035] In this embodiment, rotating the locking disc 61 drives the rotating gear 62 to rotate counterclockwise. The rotating gear 62 drives the toothed plate 63 to move to the left, which in turn drives the horizontal shaft 64 to press the transmission member 65. The transmission member 65 rotates around the fixed member 66, which in turn pushes the locking shaft 67 upward. The locking shaft 67 passes through the stabilizing tube 68 and is inserted into the lock hole of the wall to lock the body of the blast door 1.

[0036] The working principle and usage process of this utility model are as follows: First, the fixed back plate 31 is fixed to the wall with multiple sets of bolts to form a basic support point. Then, the rotating shaft 41 is supported by the support plate 35 to form a limiting support. At the same time, the support plate 35 abuts against the inner ring of the bearing 33 and rotates using the rotating shaft 41.

[0037] Subsequently, the rotating parts 43 fixed on the upper and lower parts of the edge of the air defense door body 1 are connected with the connecting rod 42, and the rotating shaft 41 forms a preliminary positioning support for the air defense door body 1. At the same time, the air defense door body 1 rotates when it is opened and closed. The support frame 51 can share the pressure of the connecting rod 42. The pressure is transmitted to the fixed back plate 31 through the pad 52 and the pad tube 53. The L-shaped plate 36 on one side of the fixed back plate 31 further strengthens the support function.

[0038] When the main body 1 of the air defense door is closed, the locking disc 61 can be rotated to drive the rotating gear 62 to rotate counterclockwise. The rotating gear 62 drives the tooth plate 63 to move to the left, which in turn drives the horizontal shaft 64 to press the transmission component 65. The transmission component 65 rotates around the fixed component 66, which in turn pushes the locking shaft 67 upward. The locking shaft 67 passes through the stabilizing tube 68 and is inserted into the lock hole of the wall to lock the main body 1 of the air defense door. The sealing strip 2 can isolate harmful gases from the outside.

[0039] When the main body 1 of the air defense door is opened, the rotatable knob 73 drives the spiral shaft 72 to rotate in the auxiliary plate 71. The spiral shaft 72 and the auxiliary plate 71 move downward relative to each other through the spiral action. Then, the disc 74 drives the bottom column 75 to abut against the ground to form support and horizontal friction, reducing the support pressure of the support component 5 and preventing its deformation from causing the main body 1 of the air defense door to sag.
