Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, and relates to splicable guardrails, and in particular to a guardrail fixing structure and guardrail that are easy to install quickly. Background Technology

[0002] Fences are common man-made structures, typically made of wood, metal, plastic, stone, or composite materials, used to demarcate boundaries, provide security, offer privacy, or decorate the environment. Existing technologies have some shortcomings in terms of installation processes and materials. Installation often relies on specialized tools and skills, is complex, time-consuming, and labor-intensive, and makes subsequent maintenance and adjustments difficult. Traditional fence materials are prone to aging or damage, and their irregular shapes and high weight lead to excessively high installation costs. To address these issues, people have conducted extensive research and proposed various solutions.

[0003] For example, Chinese patent literature discloses a high-efficiency splicing fence [Application No.: CN 201821476427.9], including a fence body, a first pin, a fence post body, a fence rod, a second pin, and pre-embedded piles. The fence post body is fixedly installed at the inner end of the fence body, the first pin is fixedly inserted into the side end of the fence post body, the fence rod is rotatably connected to the side end of the fence post body, the second pin is fixedly inserted into the bottom front end of the fence post body, and the pre-embedded piles are fixedly installed at the bottom end of the fence post body. The fence post body includes a fence post head, a rotating retaining shaft, a first pin hole, a fence post, a rotating shaft, a second pin hole, and a square groove. The fence post is fixedly installed at the inner end of the fence post body, the fence post head is fixedly installed at the rear end of the fence post, and the rotating retaining shaft is symmetrically fixedly installed at both ends of the fence post. This high-efficiency splicing fence has the advantage of high installation efficiency.

[0004] While the above solution improves installation efficiency, the installation method is still not simple enough. Furthermore, its complex structure, containing multiple components, results in high transportation, installation, and usage costs. Summary of the Invention

[0005] The purpose of this utility model is to address the above-mentioned problems by providing a guardrail fixing structure that is simple to install and easy to install quickly.

[0006] Another objective of this invention is to provide a guardrail fixing structure that facilitates quick installation of the guardrail.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a guardrail fixing structure that is easy to install quickly, including a first through hole and a second through hole respectively provided on a first pole and a second pole, the ends of the first through hole and the second through hole being joined together, and a snap-fit ​​component for fixing the first pole and the second pole being inserted into the first through hole and the second through hole.

[0008] By connecting the first and second through holes located on the first and second poles with snap-fit ​​connectors, the first and second poles can be quickly connected into one unit, achieving the effect of rapid installation of the guardrail.

[0009] In the aforementioned guardrail fixing structure that facilitates quick installation, the snap-fit ​​component includes a cap with a maximum outer diameter larger than the diameters of the first and second through holes. One end of the cap has at least two pins distributed circumferentially, capable of axially passing through the first and second through holes. One end of each pin is connected to the cap, and the other end has a radially enlarged portion that prevents axial displacement of the snap-fit ​​component after the pin passes through the first and second through holes. Furthermore, there is a radial clearance between at least the outer ends of adjacent pins. Multiple circumferentially distributed pins can evenly distribute the load, improving shear and torsional resistance compared to a single-pin structure, thus enhancing the overall structural reliability.

[0010] In the aforementioned guardrail fixing structure that facilitates quick installation, the radially enlarged portion includes a protrusion extending radially outward at the other end of the pin. The protrusion and the through-hole form a rigid restraint, ensuring a stable connection even under vibration or lateral loads, effectively preventing the risk of loosening.

[0011] In the aforementioned guardrail fixing structure that facilitates quick installation, a radial clearance is provided between each pair of adjacent pins. This radial clearance design allows the pins to undergo an inward elastic deformation when inserted into the through-hole, enabling the enlarged portion to pass smoothly through. Once fully inserted, the pins return to their original shape due to their elasticity, and the enlarged portion automatically forms a mechanical latch, allowing for tool-free, quick installation.

[0012] This invention relates to a railing fixing structure that facilitates quick installation. The railing includes N first rods distributed vertically and arranged horizontally, where N ≥ 2. The N first rods are connected by M second rods distributed horizontally and arranged vertically. The first rods and second rods intersect, and each intersection is provided with a first through hole and a second through hole.

[0013] By connecting multiple first and second poles in a crisscross pattern, the main grid-like skeleton of the guardrail is formed, which allows external forces to be distributed and transmitted through multiple nodes, avoiding stress concentration on a single pole, and can significantly improve the bending, shear and torsional resistance.

[0014] In the above-mentioned guardrail fixing structure that facilitates quick installation, the first pole is strip-shaped and flat, and a first strength reinforcement structure is provided on both sides of the first pole.

[0015] And / or, the second rod is strip-shaped and flat, with a second strength reinforcement structure on both sides. Adding reinforcement structures to the key stress areas on both sides of the rod, rather than thickening the rod as a whole, reduces material usage while ensuring strength, achieving a balance between lightweight and high strength by lowering weight and cost.

[0016] In the guardrail fixed by the above-mentioned guardrail fixing structure that is easy to install quickly, the first strength reinforcement structure includes a first half tube that extends axially and has an arched cross bracing surface, and the first half tube is integrated with the first rod body.

[0017] And / or, the second strength reinforcement structure includes a second half-tube extending axially and having an arched cross-bracing surface, the second half-tube being integrally connected to the second rod. The geometry of the arched half-tube can evenly distribute external loads as axial pressure along the arched surface, avoiding local stress concentration, providing stronger resistance to instantaneous impacts, and making it less prone to permanent plastic deformation.

[0018] In the aforementioned guardrail fixing structure designed for quick and easy installation, both the first and second rods are flat and strip-shaped. The first reinforcement structure of the first rod faces the back of the guardrail, while the second reinforcement structure of the second rod faces the front. The flat surfaces of the first and second rods are fitted together. This flat surface fit provides a planar reference, ensuring precise alignment of the through holes. No repeated adjustments are needed when inserting the pins, facilitating quick installation.

[0019] In the aforementioned guardrail fixing structure that facilitates quick installation, an anti-climb structure is provided at the upper end of the second pole. The anti-climb structure further enhances the safety of the guardrail, and its integrated design ensures overall structural strength.

[0020] In the aforementioned guardrail fixing structure that facilitates quick installation, posts are provided on both sides of the N second poles, connected to the ends of the second poles. The ends of the second poles pass through the side holes of the posts and are engaged or fixedly connected to them. The posts fix the two ends of the second poles through the side holes, transferring the load borne by the transverse poles to the posts and then distributing it to the ground, thus preventing overload bending of the middle of the poles.

[0021] Compared with existing technologies, this easy-to-install guardrail fixing structure and the guardrail it fixes have the following advantages: 1. The snap-on pins and pre-processed poles and posts enable "plug-and-play" installation, resulting in high efficiency. 2. In case of partial damage, only the pole or pin needs to be replaced without damaging the overall structure, resulting in low maintenance costs. 3. The semi-tube cavity and thin-walled pole design reduces material density while ensuring strength, thereby lowering production and usage costs. 4. The two-way pole fitting structure makes the overall structure stronger, more robust, stable, durable, and less prone to damage. Attached Figure Description

Detailed Implementation

[0029] like Figures 1 to 6 As shown, a guardrail fixing structure that is easy to install quickly includes a first through hole 11 and a second through hole 21 respectively provided on a first rod 1 and a second rod 2. The ends of the first through hole 11 and the second through hole 21 are joined together, and a snap-fit ​​member 3 for fixing the first rod 1 and the second rod 2 is inserted into the first through hole 11 and the second through hole 21.

[0030] In this embodiment, the first rod 1 and the second rod 2 are made of metal materials such as aluminum and iron. The first through hole 11 and the second through hole 21 are connected by the snap-fit ​​3, thereby achieving the effect of connecting the first rod 1 and the second rod 2 into one unit.

[0031] More specifically, the snap-fit ​​component 3 includes a cap 31 with a maximum outer diameter larger than the diameter of the first through hole 11 and the diameter of the second through hole 21. One end of the cap 31 is provided with at least two pins 32 distributed along its circumference that can axially pass through the first through hole 11 and the second through hole 21. One end of the pin 32 is connected to the cap 31, and the other end is provided with a radially enlarged portion 33 that can prevent the snap-fit ​​component 3 from axially shifting after the pin 32 passes through the first through hole 11 and the second through hole 21. Furthermore, there is a radially movable gap 34 between at least the outer ends of two adjacent pins 32.

[0032] like Figure 5 As shown, the radially enlarged portion 33 includes a protrusion 35 disposed on the other end of the pin 32 and extending radially outward.

[0033] More specifically, a radial clearance 34 is provided between each pair of adjacent pins 32.

[0034] like Figures 1 to 5 As shown, a guardrail fixing structure that is easy to install quickly includes two first rods 1 that are distributed vertically and arranged horizontally. The two first rods 1 are connected by ten second rods 2 that are distributed horizontally and arranged vertically. The first rods 1 and the second rods 2 intersect, and a first through hole 11 and a second through hole 21 are provided at the intersection.

[0035] More specifically, the first rod 1 is strip-shaped and flat, and a first strength reinforcement structure 12 is provided on both sides of the first rod 1;

[0036] The second rod 2 is flat and strip-shaped, and a second strength reinforcement structure 22 is provided on both sides of the second rod 2.

[0037] More specifically, the first strength reinforcement structure 12 includes a first half-tube 13 extending axially and having an arched cross bracing surface, the first half-tube 13 being integrally connected with the first rod 1;

[0038] The second strength reinforcement structure 22 includes a second half-tube 23 that extends axially and has an arched cross bracing surface, and the second half-tube 23 is integrated with the second rod 2.

[0039] More specifically, both the first pole 1 and the second pole 2 are flat and strip-shaped, with the first reinforcement structure 12 of the first pole 1 facing the back of the guardrail and the second reinforcement structure 22 of the second pole 2 facing the front of the guardrail. The flat surfaces of the first pole 1 and the second pole 2 are in close contact with each other.

[0040] More specifically, an anti-climbing structure 24 is provided at the upper end of the second rod 2.

[0041] More specifically, on both sides of the two first rods 1, there are columns 4 connected to the ends of the first rods 1, and the ends of the first rods 1 are fixedly connected to the side holes 41 of the columns 4.

[0042] In this embodiment, the end of the first rod 1 forms a barb 14 at the connection with the column 4 by stamping a profile, which is directly inserted into the side hole 41 and connected to the column.

[0043] The working principle of this embodiment is that, during installation, the first rod 1 is distributed vertically and set horizontally, the second rod 2 is distributed horizontally and set vertically, the backs of the first rod 1 and the second rod 2 abut against each other, the first through hole 11 and the second through hole 21 at the intersection are aligned, and the snap-fit ​​3 is inserted from the second through hole 21 to the first through hole 11 in the positive direction.

[0044] Through the radial movement gap 34 design of the pin 32, the pin 32 can generate an inward elastic deformation when it passes through the first through hole 11 and the second through hole 21, so that the radial expansion part 33 can pass smoothly through the first through hole 11 and the second through hole 21; after it has passed through completely, the pin 32 returns to its original shape by its own elasticity, and the radial expansion part 33 automatically forms a mechanical buckle structure to connect and fix the first rod 1 and the second rod 2.

[0045] After repeatedly performing the above process to connect the first rod 1 and the second rod 2, insert the end of the first rod 1 into the side hole 41 of the column 4 to complete the installation.

[0046] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0047] Although this document frequently uses terms such as first rod, first through hole, first reinforcement structure, first half-tube, barb, second rod, second through hole, second reinforcement structure, second half-tube, anti-climb structure, snap-fit, cap, pin, radial expansion, radial clearance, protrusion, column, and side hole, the possibility of using other terms is not excluded.
