[0022] The utility model discloses a foundation pit guardrail that is easy to assemble and transport. It is mainly used in scenarios where installation or disassembly is complicated, occupies a large space, is inconvenient to transport, and has high transportation or storage costs, which is not conducive to quickly responding to the needs of different construction scenarios.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 A foundation pit guardrail that is easy to assemble and transport, comprising a base 1, a first column 2, and a first crossbar 4, and further comprising:

[0024] Assembly mechanism: The assembly mechanism is arranged on the outer walls on both sides of the first column 2. The outer walls on both sides of the first column 2 are connected to the second column 3. Both ends of the second column 3 are provided with assembly grooves 16. A limiting hole 12 is provided on the inner wall of one side of the assembly groove 16. A push block is connected to the bottom inner wall of the assembly groove 16 through a spring. The top outer wall and one side outer wall of the push block are respectively connected to a fixing rod 10 and a push rod 11. A fixing groove is provided on the bottom outer wall of the first cross bar 4. The fixing rod 10 is inserted into the inner wall of the fixing groove.

[0025] Folding mechanism: The folding mechanism is arranged on the bottom outer wall of the first cross bar 4.

[0026] In a specific embodiment, a modular design is adopted, and a spring is used to push a push block to push the fixing rod 10 into the assembly groove 16 to achieve vertical fixation between the first cross bar 4 and the second column 3. It is both stable and fast, and can be quickly assembled and disassembled without complicated tools or professional skills, thereby improving work efficiency. During transportation or storage, the various components of the guardrail can be disassembled into smaller units for packaging, thereby saving space, reducing floor space, and reducing costs.

[0027] Reference Figure 2 and Figure 3 In a preferred embodiment, slots 9 are opened on the outer walls of both sides of the first column 2, and both ends of the first cross bar 4 are connected with insertion rods 14, which are inserted into the inner walls of the slots 9, and the length of the insertion rods 14 is adapted to the depth of the slots 9.

[0028] Through the close cooperation between the slot 9 and the insertion rod 14 in the assembly mechanism, the transverse connection between the first column 2 and the first cross bar 4 is achieved, which enhances the structural stability of the entire foundation pit guardrail, simplifies the installation process of the foundation pit guardrail, and improves construction efficiency.

[0029] Reference Figure 3 In a preferred embodiment, the push rod 11 is slidably inserted into the inner wall of the limiting hole 12 , and the diameter of the push rod 11 is adapted to the width of the limiting hole 12 .

[0030] When separating the first cross bar 4 and the second column 3, no additional tools are required and no complicated operating steps are required. The operator only needs to push the push rod 11 to automatically disengage the fixing rod 10 from the fixing groove by squeezing the spring, thereby completing the separation. This greatly simplifies the separation process and improves work efficiency.

[0031] Reference Figure 2 、 Figure 3 and Figure 4In a preferred embodiment, the folding mechanism includes four frames 7, and mounting grooves 13 are opened on the top and bottom outer walls of the four frames 7, and the connection points of two adjacent frames 7 are hinged to each other. The bottom outer wall of the first cross bar 4 is connected to the second cross bar 5, and the second cross bar 5 is inserted into the inner wall of the mounting groove 13. A threaded hole is opened at one end of the second cross bar 5, and a fixing sleeve 6 is installed at the end of the second cross bar 5 close to the threaded hole.

[0032] The second crossbar 5 and the four frames 7 are used in conjunction with each other.

[0033] Through the hinged design between the frames 7, the entire foundation pit guardrail can be folded when not in use, which greatly reduces the volume of the guardrail and facilitates transportation and storage. At the construction site where a foundation pit guardrail needs to be set up, the operator can quickly unfold the folded frame 7 and insert the second cross bar 5 into the installation groove 13 for fixation, thereby quickly forming an effective safety protection barrier and improving construction efficiency.

[0035] The screw 15 passes through the mounting hole and is screwed into the threaded hole to fix the second cross bar 5 to the frame 7. This mechanical connection method ensures the stability of the connection point and prevents safety hazards caused by loosening or falling off during use.

[0036] Reference Figure 4 In a preferred embodiment, baffles 8 are fixed on the inner walls of the four frames 7, and a plurality of ventilation holes arranged at equal distances are opened on the outer wall of one side of the baffle 8.

[0037] The design of the ventilation holes allows the wind to be dispersed when passing through the guardrail, reducing the concentrated effect of wind pressure on a certain part of the guardrail, helping to reduce the risk of damage to the guardrail due to excessive wind force, thereby improving the stability of the guardrail.

[0038] Working principle: When in use, the staff first unfolds the folded frame 7, and inserts the second cross bar 5 into the mounting groove 13, uses the screw 15 to pass through the mounting hole and screw it into the threaded hole to fix it, and then pushes the push rod 11 to drive the fixing rod 10 back to the assembly groove 16, aligns the insertion rod 14 with the slot 9 and inserts it, then releases the push rod 11, and the fixing rod 10 is pushed into the fixing groove to be fixed, and the overall guardrail assembly is completed.
