Description

Technical Field

[0001] This utility model belongs to the field of fence technology, and relates to splicable fences, and in particular to a quick-installation fence. 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 drawbacks 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.: CN201821476427.9], 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 invention is to address the aforementioned problems by providing a quick-assembly type fence.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A quick-installation fence includes several intersecting first and second poles. The intersections of the first and second poles are fixed by quick-installation structures. The quick-installation structure includes a semi-circular hoop that hugs the first pole. The two ends of the semi-circular hoop are respectively provided with positioning ears that abut against the second poles. The positioning ears are fixed to the second poles by snap-fit ​​members. The snap-fit ​​members pass through the first snap-fit ​​hole of the positioning ear and the second snap-fit ​​hole of the second pole and are axially limited and connected.

[0007] The first and second rods are connected in an alternating manner, ensuring structural strength while facilitating assembly. Furthermore, the quick-assembly structure uses pin-type snap-fit ​​connectors to fix the first and second rods, further simplifying rapid assembly.

[0008] In the aforementioned quick-installation fence, the snap-fit ​​component includes a cover plate located outside the first snap-fit ​​hole, with its inner periphery able to abut against a positioning ear. The inner end of the cover plate is provided with N pins, where N≥1. One end of each pin is connected to the cover plate, and the other end has an enlarged portion. This enlarged portion is located at the end of the second snap-fit ​​hole furthest from the first snap-fit ​​hole and has a diameter larger than the second snap-fit ​​hole. The enlarged portion of the pin adopts a gradually expanding tapered design, undergoing elastic deformation upon insertion to pass through the second snap-fit ​​hole. After passing through, the end of the enlarged portion forms a mechanical stop surface, enabling automatic locking after insertion.

[0009] In the aforementioned quick-installation fence, the N pins are distributed circumferentially along the cover plate, where N≥2, and a radial clearance is provided between adjacent pins. The circumferentially distributed N≥2 pins form a ring-shaped moment-bearing structure, which can decompose the load, making the load borne by each pin smaller, achieving stress dispersion, and helping to improve the overall stability and durability of the structure.

[0010] In the aforementioned quick-installation fence, the enlarged portion includes a radially outward protrusion located on the other end of the pin. This radial protrusion forms a one-way anti-reverse structure after the snap-fit ​​component is inserted into the snap-fit ​​hole, eliminating the need for manual secondary locking and simplifying the assembly process.

[0011] In the aforementioned quick-installation fence, the first pole has a columnar cross-section, and the second pole has a flat cross-section. The columnar first pole provides axial compressive strength, while the flat second pole provides planar bending strength. Both have regular structural shapes that facilitate transportation, thus saving on transportation costs.

[0012] In the aforementioned quick-installation fence, the second pole is equipped with a pole strength reinforcement structure. This reinforcement structure further increases the structural strength of the second pole, thereby enhancing the overall stability of the system.

[0013] In the aforementioned quick-installation fence, the pole reinforcement structure includes semi-circular tubes on both sides of the second pole, which are integrally connected to the second pole. The flat pole and the semi-circular tubes form an I-beam-like cross-section, and the semi-circular tubes on both sides provide symmetrical support, which can improve the torsional stiffness and overall strength of the second pole.

[0014] In the aforementioned quick-installation fence, the semicircular tube is an open semicircular tube with the opening facing the first pole. The open semicircular tube structure reduces material density, thereby lowering production and user costs.

[0015] In the aforementioned quick-installation fence, the positioning ears are provided with positioning protrusions located on both sides of the second pole. These positioning protrusions not only facilitate installation but also ensure installation accuracy, preventing structural strength reduction due to improper installation.

[0016] In the aforementioned quick-assembly fence, several first poles are distributed laterally and arranged axially, while several second poles are distributed axially and arranged laterally. The first and second poles are staggered to form an orthogonal grid layout, ensuring structural strength while facilitating assembly.

[0017] Compared with existing technologies, the advantages of this quick-installation fence are: 1. The quick-installation structure and poles are connected by pins, resulting in high installation efficiency. 2. In case of partial damage, the poles or quick-installation structure can be replaced individually without damaging the overall structure, resulting in low maintenance costs. 3. The semi-circular tube structure and flat pole design reduce production and usage costs while ensuring strength. 4. The columnar vertical pole structure makes the overall structure stronger, more stable, durable, and less prone to damage. Attached Figure Description

Detailed Implementation

[0025] like Figures 1 to 6As shown, this quick-installation fence includes several intersecting first poles 1 and second poles 2. The intersections of the first poles 1 and second poles 2 are fixed by quick-installation structures 3. The quick-installation structure 3 includes a semi-circular hoop 31 that hugs the first pole 1. The two ends of the semi-circular hoop 31 are respectively provided with positioning ears 32 that abut against the second pole 2. The positioning ears 32 are fixed to the second pole 2 by snap-fit ​​members 4. The snap-fit ​​members 4 pass through the first snap-fit ​​hole 33 of the positioning ear 32 and the second snap-fit ​​hole 21 of the second pole 2 and are axially limited and connected.

[0026] In this embodiment, the first rod 1, the second rod 2, the quick-release structure 3, and the snap-fit ​​component 4 are all made of high-strength composite materials. They are connected by the snap-fit ​​component 4 through the first snap-fit ​​hole 33 of the positioning ear 32 and the second snap-fit ​​hole 21 of the second rod 2. The first rod 1 and the second rod 2 are then controlled to abut together by the semi-circular hoop 31 that fits the shape of the first rod 1, so as to achieve the effect of connecting the first rod 1 and the second rod 2 into one.

[0027] More specifically, the snap-fit ​​component 4 includes a cover plate 41 located outside the first snap-fit ​​hole 33 and whose inner periphery can abut against the positioning ear 32. The inner end of the cover plate 41 is provided with four pins 42. One end of the pins 42 is connected to the cover plate 41, and the other end is provided with a bulge 43. The bulge 43 is located on the end of the second snap-fit ​​hole 21 away from the first snap-fit ​​hole 33 and its diameter is larger than that of the second snap-fit ​​hole 21.

[0028] like Figure 5 As shown, four pins 42 are distributed upwards around the cover plate 41, and a radial movable gap 44 is provided between two adjacent pins.

[0029] More specifically, the enlarged portion 43 includes a radially outward protrusion 45 disposed on the other end of the pin 42.

[0030] More specifically, the first rod 1 has a columnar cross-section, while the second rod 2 has a flat cross-section.

[0031] More specifically, the second rod 2 is provided with a rod strength reinforcement structure 22.

[0032] More specifically, the rod strength reinforcement structure 22 includes semi-circular tubes 23 disposed on both sides of the second rod 2, and the semi-circular tubes 23 are integrated with the second rod 2.

[0033] More specifically, the semicircular tube 23 is an open semicircular tube with the opening facing the first rod 1.

[0034] like Figure 6 As shown, the positioning ear 32 is provided with positioning protrusions 34 located on the two side walls of the second rod 2 respectively.

[0035] In this embodiment, the positioning protrusion 34 is located on both sides of the positioning ear 32, protruding outward and locking onto the two side walls of the second rod body 2, and the positioning protrusion 34 extends partially into the opening of the semi-circular tube 23.

[0036] More specifically, a number of first rods 1 are distributed laterally and arranged axially, and a number of second rods 2 are distributed axially and arranged laterally.

[0037] The working principle of this embodiment is that, during installation, the first rod 1 is distributed laterally and set axially, the second rod 2 is distributed axially and set laterally, the first rod 1 and the second rod 2 abut against each other, and a quick-installation structure 3 is set at the intersection. The first snap-fit ​​hole 33 of the positioning ear 32 and the second snap-fit ​​hole 21 of the second rod 2 are aligned, and the snap-fit ​​piece 4 is inserted from the second snap-fit ​​hole 21 to the first snap-fit ​​hole 33 in the forward direction.

[0038] The radial movement gap 44 of the pin 42 allows the pin 42 to undergo an inward elastic deformation when it enters the first locking hole 33 and the second locking hole 21, so that the enlarged part 43 can pass smoothly through the first locking hole 33 and the second locking hole 21. After it has passed through completely, the pin 42 returns to its original shape by its own elasticity, and the enlarged part 43 automatically forms a mechanical buckle structure to connect and fix the first rod 1 and the second rod 2.

[0039] After repeatedly performing the above process to connect the first rod 1, the second rod 2, and the quick-connect structure 3, the installation is complete.

[0040] 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.
