DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, the vertical guardrail 1 and the horizontal guardrail 2 are both pipe profiles, the vertical guardrail 1 and the horizontal guardrail 2 are staggered and fixed by a pipe connector 3 to form a guardrail structure with a vertical surface, the material of the pipe profile can be an aluminum profile, the quick-release base corresponds to the lower end of the vertical guardrail close to the ground, the quick-release base includes a base 4, the bottom end of the base 4 is fixedly connected to the ground, the quick-release base also includes a guardrail connecting part 5 and a quick-release assembly, the guardrail connecting part 5 and the quick-release assembly are arranged at the upper end of the base, the guardrail connecting part 5 is a column vertical in the length direction, and has an opening facing upward, a recessed The first groove portion 501 is directed vertically downward, and the shape of the first groove portion 501 is adapted to the cross-sectional shape of the vertical guardrail 1. The bottom end of the vertical guardrail 1 can be inserted into the first groove portion 501. The quick-release component connects the vertical guardrail 1 and the first groove portion 501 in an operable limit connection, that is, the position of the vertical guardrail 1 relative to the first groove portion 501 can be fixed by operating the quick-release component state, and the relative fixed state of the vertical guardrail 1 relative to the first groove portion 501 can be released by operating the quick-release component state, thereby completing the quick disassembly and assembly between the vertical guardrail 1 and the base 4.

[0026] In some embodiments, Figures 2 to 6As shown, the quick-release assembly has a limiting rod 6 and a limiting connection part 7. The limiting connection part 7 protrudes from the side surface of the guardrail connection part 5. The limiting hole 8 horizontally penetrates the end of the limiting connection part 7 away from the guardrail connection part 5 and the end of the first groove part 501 close to the limiting connection part 7. The limiting rod 6 is horizontally penetrated in the limiting hole 8. A positioning hole 101 is provided on one side of the bottom end of the vertical guardrail 1. The shape of the positioning hole 101 is adapted to the cross-section of the limiting rod 6. When the bottom end of the vertical guardrail 1 is placed in the first groove part 501, the limiting rod 6 is in the first position, that is, the limiting rod 6 is penetrated in the limiting hole 8 and at least partially passes through the limiting hole 8 and is placed in the positioning hole 101. The limiting rod 6 limits the vertical direction of the vertical guardrail 1, and the first groove part 501 limits the horizontal direction of the vertical guardrail 1. The vertical guardrail 1 is in a fixed state relative to the base 4 and the ground. When the limiting rod 6 is located at the second position, that is, one end of the limiting rod 6 is not placed in the positioning hole 101, the limiting effect of the limiting rod 6 on the vertical guardrail 1 is released, and the vertical guardrail 1 can be moved out of the first groove portion 501 in the vertical direction, thereby releasing the fixed state of the vertical guardrail 1 relative to the base 4 and the ground, and completing the disassembly of the vertical guardrail 1.

[0027] In some embodiments, Figures 2 to 6 As shown, the limiting connection part 7 has a second groove part 701 which is recessed downward, and the spring 9 is placed in the second groove part 701 and is limited in the second groove part 701 in the horizontal direction. The spring 9 is sleeved on the limiting rod 6, and one end of the spring 9 is limitedly connected to one end of the limiting rod 6 close to the guardrail connection part 5. The spring 9 is in a compressed state in the second groove part 701, that is, the spring 9 has a thrust on the limiting rod 6 toward the guardrail connection part 5. When the bottom end of the vertical guardrail 1 is placed in the first groove part 501 and adjusted to the positioning hole 101 opposite to the limiting hole 8, the limiting rod 6 moves toward the positioning hole 101 in the limiting hole 8 under the action of the spring 9 and is placed in the positioning hole 101, which is convenient for installation. If the limiting rod 6 needs to be moved out of the positioning hole 101, a reverse force that overcomes the restoring force of the spring 9 needs to be applied, which effectively prevents misunderstanding of the connection state and improves safety.

[0028] In some embodiments, Figures 2 to 6 As shown, a thread is provided at one end of the limiting rod 6 close to the guardrail connecting portion 5, and a nut 10 is provided on the thread. The diameter of the nut 10 is larger than the diameter of the limiting rod 6 and larger than the diameter of the spring 9. The nut 10 limits the spring 9 to the end of the limiting rod 6 where the nut 10 is provided, that is, the nut 10 limits the spring 9 to the end of the limiting rod 6 close to the guardrail connecting portion 5. The diameter of the nut 10 is smaller than the diameter of the positioning hole 101, so that when the limiting rod 6 is in the first position, the nut 10 is placed in the positioning hole 101, thereby completing the limitation of the vertical guardrail 1 in the vertical direction.

[0029] In some embodiments, Figures 2 to 6As shown, the gasket 11 is placed in the second groove portion 701 and is limited in the horizontal movement direction range in the second groove portion 701. The gasket 11 is provided with a through hole penetrating the two surfaces. The limiting rod 6 passes through the through hole and passes through the gasket 11. The aperture of the through hole is smaller than the outer diameter of the spring 9, and the aperture of the through hole is smaller than the aperture of the nut 10. One side of the gasket 11 abuts against one end of the spring 9 close to the guardrail connecting portion 5, and the other side of the gasket 11 abuts against the nut 10, that is, the gasket 11 is clamped between the spring 9 and the nut 10. This embodiment is suitable for when the diameter of the spring 9 is larger than the diameter of the nut 10, then the gasket 11 is used to ensure that the spring 9 is limited at one end of the limiting rod 6 close to the guardrail connecting portion 5.

[0030] In some embodiments, Figures 2 to 6 As shown, the end of the limit rod 6 away from the guardrail connection part 5 is provided with a bent portion 601, and the bent portion 601 is located outside the limit connection part 7, so that the limit rod 6 can be at least partially limited outside the limit connection part 7, preventing the limit rod 6 from being completely placed in the limit connection part 7, and avoiding the problem that the limit rod 6 cannot be manually pulled out. At the same time, the surface of the bent portion 601 is provided with a continuous raised anti-slip structure, which is convenient for the operator to pull the limit rod 6 and prevent it from being pulled loose.

[0031] In some embodiments, Figures 2 to 6 As shown, the end of the first groove portion 501 away from the ground is provided with a circumferential guide portion 5011 in the shape of an inclined surface, and the inclination direction of the circumferential guide portion 5011 is downward from the surrounding to the center direction. The bottom end of the vertical guardrail 1 is guided by the circumferential guide portion 5011 and then enters the first groove portion 501, so as to facilitate the vertical guardrail 1 to be inserted into the guardrail connecting portion 5.

[0032] In some embodiments, Figures 2 to 6 As shown, vertical mounting holes 12 are provided on both sides of the base 4 relative to the guardrail connecting part 5. Bolts pass through the vertical mounting holes 12 and are screwed to the ground. The bolt connection facilitates the installation and disassembly of the base 4, and the position of the base 4 can be fixed according to actual needs.

[0033] In some embodiments, the base 4, the guardrail connection portion 5 and the limiting connection portion 7 can be integrally formed to improve structural strength and reduce the number of parts.
