[0036] The inventor found in practice that the locking piece needs to be fixed by multiple bolts during use, and the two right-angle surfaces of the support block also need to be adjusted to be flush with the two right-angle surfaces of the convex edge, which increases the construction procedure and reduces the construction efficiency, and the four support devices are separately provided, which can only ensure that the door frame is perpendicular to each other, and cannot support the door frame.

[0037] Based on the above finding, the application provides a civil air defense construction door frame support device, which can simplify the construction process, improve work efficiency, and support the door frame to ensure the stability of the door frame during construction. Embodiments

[0038] Referring to Figures 1-8 The application discloses a civil air defense construction door frame support device, which comprises a door frame 1, clamping assemblies arranged at four corners of the door frame 1, and telescopic assemblies fixedly connected with the clamping assemblies.

[0039] The door frame 1 comprises a rectangular frame formed by two mutually parallel cross beams 101 and two mutually parallel longitudinal beams 102 connected end to end in sequence.

[0040] Specifically, the clamping assembly comprises a right-angle support 2, a right-angle constraint block 3 sliding in the right-angle support 2, and a fixer connecting and fixing the right-angle support 2 and the right-angle constraint block 3, wherein the fixer is a bolt 302 and a nut 303, the bolt 302 passes through two waist grooves 201 and a through hole 301, and the nut 303 is tightened and fixed.

[0041] Further, the right-angle constraint block 3 is provided with a through hole 301 in the center, and the bolt 302 can pass through the through hole 301 to provide conditions for fixing the right-angle support 2 and the right-angle constraint block 3.

[0042] Further, the right-angle support 2 is a triangular cavity matched with a right-angle part of the door frame 1, the right-angle support 2 is provided with waist grooves 201 in a direction extending towards and bisecting the right-angle, and the waist grooves 201 respectively pass through two opposite surfaces of the right-angle support 2, so that the position of the right-angle constraint block 3 can be adjusted to make the clamping assembly adapt to door frames 1 of different thicknesses. The right-angle support 2 wraps the four corners of the door frame 1 and has excellent stability. When in use, only the right-angle support 2 matched with the size of the door frame 1 needs to be customized, and then a pair of right-angle supports 2 and the right-angle constraint block 3 are fixed by using the fixer, thereby obviously improving work efficiency.

[0043] As an example, when in use, the cross beams 101 and the longitudinal beams 102 perpendicular to each other of the door frame 1 are loaded into the right-angle support 2, the right-angle constraint block 3 is then put into the right-angle of the door frame 1 to be constrained, and finally the bolt 302 and the nut 303 are used for fixing, that is, the four corners of the door frame 1 are fixed by the clamping assembly, thereby simplifying the installation procedure of the clamping assembly and improving work efficiency.

[0044] The telescopic assembly comprises two pairs of vertical longitudinal telescopic rods 4 and transverse telescopic rods 5, the longitudinal telescopic rods 4 and the transverse telescopic rods 5 are both fixed on the right-angle constraint block 3, and form a rectangular frame.

[0046] When the longitudinal telescopic rod 4 is used, the first motor 403 is started to drive the first screw rod 404 to rotate, the rotation of the first screw rod 404 causes the first nut 405 to move forward relative to the first screw rod 404, and the first bracket inner tube 402 is synchronously driven to extend out of the first bracket outer tube 401.

[0047] The transverse telescopic rod 5 comprises a second bracket outer tube 501, two second bracket inner tubes 502 symmetrically arranged with respect to the second bracket outer tube 501, the second bracket inner tubes 502 being slidingly arranged in the second bracket outer tube 501, a second motor 503 fixedly arranged at the middle of the second bracket outer tube 501, a second screw rod 504 arranged on the second motor 503, and two second nuts 505 respectively sleeved on two ends of the second screw rod 504, the second nuts 505 being arranged in the second bracket inner tubes 502 and being in overfitting cooperation with the second bracket inner tubes 502.

[0048] When the transverse telescopic rod 5 is used, the second motor 503 is started to drive the second screw rod 504 to rotate, the rotation of the second screw rod 504 causes the two second nuts 505 at the two ends to move forward relative to the second screw rod 504, and the two second bracket inner tubes 502 are synchronously driven to extend out of the second bracket outer tube 501.

[0049] It is worth noting that the telescopic assembly has high speed, large power, and high precision, and can be automatically controlled through an externally arranged controller.
