[0005] The technical solution adopted by the present invention to solve its technical problems is: a laterally adjustable support device for door frames, comprising a civil air defense door frame, a support plate fixedly mounted on the top of the civil air defense door frame, a first support rod movably mounted on the left and right ends of the support plate, a support foot assembly movably mounted on the bottom end of the first support rod, the support foot assembly comprising a connecting seat, the connecting seat being movably connected to the first support rod, a bottom of the connecting seat being liftably mounted with a foot, second support rods being horizontally arranged on the left and right side walls of the civil air defense door frame, adjacent second support rods and first support rods being connected to each other via a connecting assembly.

[0006] Furthermore, connecting parts are provided at both ends of the first support rod, and ear plate seats are fixedly installed on the support plate and the connecting seat. The connecting part at the top end of the first support rod is hinged to the ear plate seat on the support plate, and the connecting part at the bottom end of the first support rod is hinged to the ear plate seat on the connecting seat.

[0007] Furthermore, the connecting assembly includes a locking collar, a collar seat is fixedly connected to the side wall of the locking collar, a locking piece is cooperatively installed on the side wall of the locking collar away from the collar seat, and another set of connecting assemblies is symmetrically provided on the side of the collar seat away from the locking collar, the collar seats of the two sets of connecting assemblies are rotatably connected by a connecting pin, and the two sets of locking collars are respectively sleeved on the first support rod and the second support rod.

[0008] Furthermore, a fixing seat is fixedly installed on the end of the second support rod, and the fixing seat is fixedly installed on the left and right inner walls of the civil air defense door frame.

[0009] Furthermore, an adjusting bolt is installed at the front end of the connecting seat, and a T-shaped block is fixedly connected to the bottom end of the adjusting bolt. A T-shaped slot matching the T-shaped block is provided on the front side wall of the base foot, and the T-shaped block is installed in the T-shaped slot. Several groups of guide columns are fixedly installed at the rear end of the base foot, and the guide columns are slidably connected to the connecting seat. Side ears are fixedly connected to the left and right side walls of the base foot, and mounting holes are provided on the side ears.

[0010] The beneficial effect of the present invention is that the design of the present invention is that the first support rod is movably installed at the left and right ends of the support plate. By adjusting the angle between the first support rod and the ground to adapt to civil defense doors of different heights, and fixing the base to the ground by fixing bolts, the first support rod is fixed. When fixing, the first support rod can be adjusted more flexibly by adjusting the distance between the base and the connecting seat, thereby improving the convenience of installing the support device. In addition, the first support rod is auxiliary supported and fixed by the second support rod, which is beneficial to improving the overall stability of the support device.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0020] according to Figure 1-6 As shown, a laterally adjustable support device for door frame installation includes a civil air defense door frame 1, a support plate 2 is fixedly installed on the top of the civil air defense door frame 1 by bolts, a first support rod 3 is movably installed on the left and right ends of the support plate 2, a support foot assembly is movably installed on the bottom end of the first support rod 3, the support foot assembly includes a connecting seat 11, the connecting seat 11 is movably connected to the first support rod 3, and a base foot 12 is installed on the bottom of the connecting seat 11 in a liftable manner, second support rods 5 are horizontally arranged on the left and right side walls of the civil air defense door frame 1, and adjacent second support rods 5 and first support rods 3 are connected to each other through a connecting assembly.

[0021] In this embodiment, a connecting portion 31 is provided at both ends of the first support rod 3, and an ear plate seat 4 is fixedly installed on the support plate 2 and the connecting seat 11. The connecting portion 31 at the top of the first support rod 3 is hinged to the ear plate seat 4 on the support plate 2, and the connecting portion 31 at the bottom end of the first support rod 3 is hinged to the ear plate seat 4 on the connecting seat 11. The end of the second support rod 5 is fixedly installed with a fixing seat 6, and the fixing seat 6 is fixedly installed on the left and right inner walls of the civil air defense door frame 1 by bolts. The connecting assembly includes a locking collar 7. A collar seat 8 is fixedly connected to the side wall of the locking collar 7. A locking piece 9 is installed on the side wall of the locking collar 7 away from the collar seat 8.
