[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment

[0025] Please refer to Figures 1 to 4 , which is an embodiment of the present utility model. This embodiment provides a technical solution: a foundation pit guardrail, including

[0026] The guardrail components 1 arranged on both sides of the foundation pit, including a plurality of triangular brackets and two cross rails 14 penetrating through the plurality of triangular brackets;

[0027] The triangular bracket includes a diagonal brace 11, a vertical brace 12 and a bottom brace 13 fixed together by bolts. One end of the bottom brace 13 is fixed to the bottom end of the vertical brace 12 by bolts. The top end of the diagonal brace 11 is fixed to the vertical brace 12 by bolts. The other end of the bottom brace 13 is fixed to the bottom end of the diagonal brace 11 by bolts;

[0028] The two cross rails 14 are installed one above the other on one side of the vertical brace 12;

[0029] A disassembly and assembly structure 16 is arranged between the cross rail 14 and the vertical brace 12, including a connecting pin 161 that penetrates through the vertical brace 12 and the cross rail 14 at the same time, an end block 162 welded and fixed on the surface of one end of the connecting pin 161 and located on one side of the cross rail 14, a limit insertion block 164 slidably installed on the surface of one side of the vertical brace 12, and a limit hole 168 opened on the surface of the other end of the connecting pin 161. The bottom end of the limit insertion block 164 penetrates through the limit hole 168 to the bottom of the connecting pin 161, which can realize the limitation of the connecting pin 161 and the quick plug-in assembly of the cross rail 14 and the vertical brace 12.

[0030] Among them, the disassembly and assembly structure 16 further includes a pressure pad 163. The pressure pad 163 is made of rubber material. The pressure pad 163 is located between the end block 162 and the cross rail 14, and the pressure pad 163 is sleeved on the connecting pin 161, so that the end block 162 can be pressed tightly against the cross rail 14 to ensure the tightness after subsequent assembly.

[0031] Among them, pin holes corresponding to the connecting pin 161 are opened on the surfaces of the cross rail 14 and the vertical brace 12 to facilitate the smooth penetration of the connecting pin 161.

[0032] Among them, the disassembly and assembly structure 16 further includes a strip-shaped slideway 167 opened on the side surface of the vertical strut 12, an inner slide seat 166 arranged on the inner wall of the vertical strut 12, and a strip-shaped slider 165 welded and fixed between the inner slide seat 166 and the limit insertion block 164. The strip-shaped slider 165 is slidably located in the strip-shaped slideway 167, so that the limit insertion block 164 can slide smoothly up and down on the side surface of the vertical strut 12.

[0033] Among them, the disassembly and assembly structure 16 further includes an inner groove 169 opened inside the bottom end of the limit insertion block 164, a spring 1610 and a triangular clamping block 1611 installed in the inner groove 169. The triangular clamping block 1611 is movably installed in the inner groove 169 through the spring 1610, and the end of the triangular clamping block 1611 pops out to the outside of the limit insertion block 164 and is stuck at the bottom of the connecting pin 161, realizing the clamping limit of the limit insertion block 164, ensuring that the limit insertion block 164 can stably limit the connecting pin 161, guaranteeing the connection stability between the vertical strut 12 and the horizontal railing 14. Subsequently, when the horizontal railing 14 and the vertical strut 12 need to be disassembled, only need to press the end of the triangular clamping block 1611 into the inner groove 169 first, so that the triangular clamping block 1611 no longer limits the limit insertion block 164. At this time, the limit insertion block 164 can be slid up, so that the limit insertion block 164 is separated from the connecting pin 161, and the limit on the connecting pin 161 can be released. Then, the connecting pin 161 is pulled out, and the horizontal railing 14 and the vertical strut 12 can be directly disassembled. When assembling the horizontal railing 14 and the vertical strut 12 in the early stage, it is the same. First, the connecting pin 161 penetrates through the horizontal railing 14 and the vertical strut 12, and the pressure pad 163 is squeezed to undergo elastic deformation until the limit hole 168 is aligned with the limit insertion block 164. Then, the limit insertion block 164 is slid down, so that the bottom end of the limit insertion block 164 is inserted into the limit hole 168 and the bottom end of the triangular clamping block 1611 is squeezed into the inner groove 169 until the bottom end of the limit insertion block 164 smoothly penetrates to the bottom of the connecting pin 161, so that the end of the triangular clamping block 1611 pops out under the push of the spring 1610 and is stuck on the bottom surface of the connecting pin 161, thus ensuring the position stability of the connecting pin 161.

[0034] Among them, one end of the spring 1610 is fixed on the inner wall of the inner groove 169, and the other end of the spring 1610 is fixedly connected to the triangular clamping block 1611, ensuring the installation stability of the spring 1610.

[0035] Among them, a pop-up hole communicating with the inner groove 169 is opened on the bottom surface of the limit insertion block 164, and the pop-up hole is adapted to the triangular clamping block 1611 for the smooth pop-up of the end of the triangular clamping block 1611.

[0036] Among them, U-shaped anchor reinforcement bars 15 are arranged on the surfaces at both ends of the bottom strut 13, and the U-shaped anchor reinforcement bars 15 are anchored in the ground.

[0037] Although embodiments of the present utility model have been shown and described (see the above detailed description), those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
