[0021] like Figure 1 , Figure 3 and Figure 4As shown, a municipal engineering construction protection device comprises at least two columns 1 and a protection plate 2 arranged between two adjacent columns 1, the upper and lower ends of the protection plate 2 are respectively provided with cross beams 3, two opposite surfaces of the column 1 are provided with slots 5 which cooperate with the cross beam 3, the bottom of the column 1 is provided with a first fixing plate 7, and the four corners of the fixing plate are provided with first fixing holes 71; the protection plate 2 comprises two mutually hinged plate bodies, the back sides of the two plate bodies close to one end are correspondingly provided with connecting blocks 4, the two connecting blocks 4 are provided with card slots 41 at one end away from each other, the two connecting blocks 4 are locked by U-shaped card blocks 6 which can be inserted into the two card slots 41, and retractable elastic locking tongues 62 are provided on both sides of the U-shaped card block 6, and locking grooves 42 which cooperate with the elastic locking tongue 62 to lock are provided on the two side walls of the card slot 41, and pressing elastic components for controlling the retractable activity of the elastic locking tongue 62 are provided on the upper sides of the U-shaped card block 6.

[0022] like Figure 2 As shown, the cross beam 3 is a hollow T-shaped profile 31, the lower part of the T-shaped profile 31 is provided with a fixing groove 32 that cooperates with the protective plate, and the inner cavity of the T-shaped profile 31 is provided with transverse and vertical ribs 33. The cross beam 3 can be formed by plastic material, which is a hollow structure with light weight. By arranging transverse and vertical ribs 33 inside, the overall strength is enhanced.

[0023] like Figure 5 and Figure 6 As shown, the pressing elastic component includes a pressing sheet 61, a spring 65 and a guide rod 64. The interior of the U-shaped block 6 is divided into an upper chamber and a lower chamber. The pressing sheet 61 is slidably arranged on both sides of the upper chamber, and the elastic lock tongue 62 is arranged on both sides of the lower two ends of the lower chamber. The guide rod 64 is transversely arranged on both sides of the upper part of the upper chamber. The spring 65 is sleeved on the outside of the guide rod 64.

By installing the oblique support rod 8, the fixation is strengthened, and it can be used according to needs.

[0025] When in use, the two plates can be unfolded through the hinge points of the two plates, and then the U-shaped block 6 is inserted into the slots 41 of the two connecting blocks 4, so that the elastic locking tongue 62 of the U-shaped block 6 extends out and is inserted into the locking slot 42 to achieve locking, forming an unfolded protective plate 2, and then the crossbeam 3 is inserted into the upper and lower ends of the protective plate 2 respectively, so that the two ends of the crossbeam 3 are inserted into the slots 5 on the column 1, and the first fixing plate 7 on the column 1 is fixed to the construction plane with fixing nails, and the operation is reversed when disassembling. The combined structure of the column 1 and the protective plate 2 is easy to install and disassemble, and the protective plate 2 is foldable, smaller in size, and convenient for handling and transportation.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
