[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a foundation pit protection railing for construction engineering, comprising a support column 1, a railing body 2, a reflector 3, and a fixing structure 4. Four fixing plates 11 are fixedly connected to both sides of the support column 1. Two railing bodies 2 are provided, rotatably connected by hinges 22. Two fixing plates 24 are fixedly connected to the side of the railing body 2 furthest from the center. A sliding rod 23 is fixedly connected to the bottom of the railing body 2. A guide rail 31 is provided at the top of the reflector 3, and the two sliding rods 23 are slidably connected to the guide rail 31. The fixing structure 4 includes a first insertion rod 43, which inserts into the first fixing plate 11 and the second fixing plate 24. The rear end of the first insertion rod 43 is engaged with a second insertion rod 46. The railing body 2 and the reflector 3 allow for quick installation and disassembly, improving portability, facilitating storage and transportation, and providing convenient and quick assembly. The fixing structure 4 allows for quick and easy fixing of the railing body 2 to the support column 1, eliminating the need for bolts and tools.

[0024] Furthermore, a groove 21 is provided on one side of the guardrail body 2 near the middle, and both ends of the hinge 22 are fixedly connected to the inner wall of the groove 21. The two guardrail bodies 2 can be folded for easy storage and transportation. The two guardrail bodies 2 can be rotated through the hinge 22 to make the two guardrail bodies 2 flat.

[0025] Furthermore, the reflector 3 has insertion holes 32 on both the front and rear sides of the right end. The reflector 3 includes a pin 33, which is inserted into the insertion hole 32. Inserting the pin 33 limits the position of the slide bar 23, thereby completing the assembly of the guardrail body 2 and the reflector 3.

[0026] Furthermore, the front side of the insertion rod 43 is fixedly connected to the limiting plate 42, and the insertion rod 43 is slidably connected to the sliding plate 45. When the insertion rod 43 is inserted, the sliding plate 45 abuts against the fixed plate 11, and the pull ring 41 is pressed, so that the spring 44 is deformed by pressure.

[0027] Furthermore, a pull ring 41 is fixedly connected to the front side of the limiting plate 42. The surface of the pull ring 41 is provided with an anti-slip coating to prevent slippage when holding the pull ring 41, making the pull ring 41 easier to hold.

Pressing the pull ring 41 causes the spring 44 to deform under pressure. Releasing the pull ring 41 causes the elastic force of the spring 44 to push the insertion rod 43 forward.

[0029] Furthermore, the second insertion rod 46 is an L-shaped insertion rod, and a slot is provided in the middle of the second insertion rod 46. The slot engages with the rear end of the first insertion rod 43. When the second insertion rod 46 is inserted, the second insertion rod 46 engages with the rear end of the first insertion rod 43. The first insertion rod 43 moves forward, so that the rear end of the first insertion rod 43 engages in the slot of the second insertion rod 46.

[0030] Working Principle: During use, when installation is required, the two guardrail bodies 2 can be folded for easy storage and transportation. The two guardrail bodies 2 are rotated via hinge 22 to lay flat, allowing the sliding rod 23 to slide into the guide rail 31. The reflector 3 fixes the position of the two guardrail bodies 2, preventing further rotation. A pin 33 is inserted to limit the position of the sliding rod 23, thus completing the assembly of the guardrail bodies 2 and reflector 3. The guardrail bodies 2 and reflector 3 allow for quick installation and disassembly, improving portability, facilitating storage and transportation, and simplifying assembly. Quick and easy to use: When installing two guardrail bodies 2, align the fixing plate 24 with the fixing plate 11, insert the first rod 43, so that the sliding plate 45 rests against the fixing plate 11, press the pull ring 41 to deform the spring 44 under pressure, then insert the second rod 46 so that the second rod 46 is engaged with the rear end of the first rod 43, release the pull ring 41, and the elastic force of the spring 44 pushes the first rod 43 forward so that the rear end of the first rod 43 is engaged in the slot of the second rod 46. The guardrail body 2 can be quickly fixed to the support post 1 through the fixing structure 4. The installation is convenient and quick, and no fixing bolts or tools are required, making it easy to use.
