[0015] like Figure 1 As shown, a civil air defense door frame fixing device includes a support rod 1, which is arranged in a semi-cylindrical shape, and also includes a clamping support mechanism 2, which is arranged at the bottom of the support rod 1. The support rod 1 is arranged horizontally so that the clamping support mechanism 2 is distributed horizontally, providing symmetrical support points or clamping points for the civil air defense door frame, so that the connection between the door frame and the device is stable.

[0016] like Figure 1-3 As shown, in order to realize the support of the bottom of the door frame and the connection between the steel bar and the door frame, the clamping support mechanism 2 includes a connecting sleeve 3, a supporting plate 4 and an adjusting component 5. The connecting sleeve 3 is arranged at the bottom of the support rod 1, and the connecting sleeve 3 is arranged symmetrically. The supporting plate 4 is arranged on the outer side wall of the connecting sleeve 3. The upper part of the supporting plate 4 is connected to the side wall of the support rod 1. The adjusting component 5 penetrates the support rod 1 and is movably connected in the connecting sleeve 3. The connecting sleeve 3 supports the support rod 1, and the supporting plate 4 increases the supporting width of the support rod 1 and cooperates with the adjusting component 5 to realize the clamping and support of the civil air defense door frame;

[0017] The adjusting assembly 5 comprises a stud 6, an adjusting block 7, a pressing plate 8 and a fixing plate 9. The stud 6 passes through the support rod 1 and is arranged in the connecting sleeve 3. The stud 6 is threadedly connected to the connecting sleeve 3. The adjusting block 7 is arranged on the upper part of the stud 6. The pressing plate 8 can be rotatably arranged on the upper part of the adjusting block 7. The fixing plate 9 can be rotatably arranged at the bottom of the stud 6. The door frame is supported by the support rod 1 and the support plate 4 to disperse the supporting strength of the bottom of the door frame. The adjusting block 7 is rotated to rotate the stud 6 in the connecting sleeve 3. The position of the connecting sleeve 3 between the pressing plate 8 and the fixing plate 9 is adjusted. The distance between the pressing plate 8 and the support plate 4 and the support plate 4 is adjusted to achieve clamping of the bottom wall of the door frame. The connecting sleeve 3 is vertically distributed with the support rod 1. The support plate 4 is at the same horizontal height as the upper part of the support rod 1. The support plate 4 is arranged in an inverted trapezoidal shape. The support plate 4 is symmetrically arranged with the connecting sleeve 3 as the center. The connecting sleeve 3 supports the support rod 1, and the support rod 1 and the support plate 4 stably support the bottom of the door frame.

[0018] Among them, a fixing hole 10 is provided in the fixing plate 9, and the fixing holes 10 are symmetrically arranged. The fixing holes 10 are used for positioning and installing the fixing plate 9, and can be bolted to the ground. The inner wall of the fixing hole 10 is provided with a groove 11, and the groove 11 is symmetrically arranged in the fixing hole 10. The steel wire is inserted into the grooves 11 on both sides to tighten the fixing plate 9 to achieve fixation of the device.

[0019] When in use, the operator places the device vertically through the fixing plate 9, so that the support plate 4 and the upper wall of the support plate 4 are in contact with the bottom wall of the door frame, and the support strength of the steel bars at the bottom of the door frame is dispersed. The adjusting block 7 is rotated to adjust the connection sleeve 3, the support rod 1 and the support plate 4 up and down, so as to achieve different support height adjustments of the support plate 4 and the support rod 1. At the same time, the adjusting block 7 is rotated to clamp the pressing plate 8 and the support plate 4 to the bottom of the door frame, so as to fix the door frame.

[0020] The device is also applicable to both sides and the upper part of the door frame. Steel wires are inserted through the fixing holes 10 and the grooves 11 on both sides of the fixing holes 10 to connect and fix the fixing plates 9 to the steel bars. The door frame is clamped and fixed by adjusting the distance between the pressing plate 8 and the supporting plate 4.
