Description

Guardrail fixed knot constructs and guardrail convenient to quick installation Technical Field The utility model belongs to the technical field of guardrails, relates to a spliced guardrail, and particularly relates to a guardrail fixing structure convenient to install rapidly and a guardrail. Background Guardrails are a common man-made structure, typically made of wood, metal, plastic, stone, or composite materials, etc., for demarcating boundaries, protecting security, providing privacy, or decorating environments. In the prior art, the prior art has defects in the aspects of installation process and materials, the installation process usually depends on professional tools and skills, is complex in process, consumes time and labor, and causes difficult later maintenance and adjustment, the traditional guardrail materials are easy to age or damage, the problems of excessively high installation cost caused by irregular shapes and higher weight are solved, and various solutions are proposed for long-term exploration. For example, china patent literature discloses a high-efficient concatenation rail [ application number: CN 201821476427.9], including rail main part, first bolt, rail stake main part, rail, second bolt and embedded pile, rail stake main part fixed mounting is at the inner of rail main part, first bolt fixed grafting is at the side of rail stake main part, the rail pole rotates to be connected at the side of rail stake main part, second bolt fixed grafting is at the front end bottom of rail stake main part, embedded pile fixed mounting is at the bottom of rail stake main part, rail stake main part includes rail stake head, rotation clamping axle, first bolt hole, rail stake, axis of rotation, second bolt hole and square groove, rail stake fixed mounting is at the inner of rail stake main part, rail stake head fixed mounting is at the rear end of rail stake, rotation clamping axle symmetry fixed mounting is at rail stake both ends. The high-efficiency spliced fence has the advantage of high installation efficiency of the device. The above-described solution, although having an improved installation efficiency, is not simple enough. On the other hand, the structure is complex, various components are contained, and the transportation and installation use costs are too high. Disclosure of Invention The utility model aims to solve the problems and provide a guardrail fixing structure which is simple in installation mode and convenient to install quickly. Another object of the present utility model is to provide a guardrail that facilitates quick installation of a guardrail-securing structure. In order to achieve the purpose, the guardrail fixing structure convenient to install rapidly comprises a first through hole and a second through hole which are respectively arranged on a first rod body and a second rod body, wherein the end parts of the first through hole and the second through hole are in butt joint, and clamping pieces for fixing the first rod body and the second rod body are arranged in the first through hole and the second through hole in a penetrating mode. The first through hole and the second through hole that are located on the first body of rod and the second body of rod are connected through the joint spare, with the first body of rod and the second body of rod quick connect as an organic wholely, realize the effect of guardrail quick installation. In the guardrail fixed knot that is convenient for install fast that above-mentioned, the joint spare include that the biggest external diameter is greater than the block of first through-hole aperture and second through-hole aperture, block one end be equipped with two piece at least along its circumferencial direction on the distribution can pass the bolt of first through-hole and second through-hole axially, bolt one end link to each other with the block, be equipped with on the other end and prevent the radial expansion portion of joint spare axial displacement after the bolt passes first through-hole and second through-hole, and have radial clearance of activity between two adjacent bolts at least outer ends. The bolts distributed on the circumference can uniformly share the load, so that the shearing resistance and the torsion resistance can be improved compared with a single bolt structure, and the overall reliability of the structure is enhanced. In the above guardrail fixing structure convenient for rapid installation, the radially expanding portion comprises a protrusion arranged at the other end of the bolt and radially outwards facing the bolt. The bulge and the through hole form a hard limit, and even if the bulge and the through hole are subjected to vibration or transverse load, the connection stability can be kept, and the loosening risk can be effectively avoided. In the guardrail fixing structure convenient to install fast, radial movable gaps are arranged between two adjacent bolts. Through the design of the radial movabl
