Description

Technical Field

[0001] This utility model relates to the field of folding grille technology, and in particular to a modular folding grille. Background Technology

[0002] Currently, the ground gratings widely used in road administration and municipal engineering projects mainly suffer from two major technical bottlenecks. First, traditional fixed or unitized gratings are bulky and rigidly connected, leading to inconvenient transportation and storage, cumbersome on-site assembly, and an inability to flexibly adapt to site shapes. Second, and more prominently, even the few existing folded gratings are designed based on ideally flat foundations. When laid on real uneven ground, the lack of an effective adaptive adjustment mechanism easily causes grating units to become suspended and unstable, resulting in a "seesaw" effect. This not only seriously threatens pedestrian and operational safety but also accelerates structural damage due to stress concentration, greatly limiting its application scenarios and service life.

[0003] Therefore, there is an urgent need for a solution that can simultaneously achieve rapid assembly, convenient storage and transportation, and fundamentally solve the problem of stable laying on uneven ground, thereby meeting the usage requirements under complex working conditions.

[0004] Therefore, we propose a modular folding grille to address the aforementioned issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular folding grille with good practicality, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular folding grille, comprising: multiple modular units, each modular unit being movably connected by at least two grille plates via a hinge arranged along its central portion, allowing the unit to switch between a folded state and an unfolded state around the hinge axis; a connecting mechanism, disposed around the periphery of the modular unit, comprising a male connecting portion and a female connecting portion, for connecting the grille plates and mounting brackets on both sides; and a support and leveling mechanism, comprising multiple support feet fixed to the bottom of the grille plates and elastic compensation pads attached to the bottom of the support feet; the support feet are used to provide a stable support height and form drainage gaps, and the elastic compensation pads absorb local unevenness of the ground through their elastic deformation, thereby achieving stable leveling of the grille plates.

[0007] Preferably, the male connecting part is a hinge disposed on both sides of the grating plate, and the female connecting part is a pivot that connects to the adjacent hinge.

[0008] Preferably, the surface of the grid plate is provided with anti-slip texture, and multiple drainage holes are formed through the grid plate.

[0009] Preferably, the support foot is integrally formed with the grid plate.

[0010] Preferably, the elastic compensation pad is made of rubber, thermoplastic polyurethane, or silicone and is bonded to the support foot by adhesive or embedded wrapping.

[0011] Preferably, the thickness of the elastic compensation pad is 5 mm to 15 mm.

[0012] Preferably, the hinge is a one-piece molded shaft structure made of engineering plastic.

[0013] Preferably, the overall outer contour shape of the modular unit is rectangular.

[0014] Preferably, a handle is provided on the outer side of the mounting bracket.

[0015] Compared with the prior art, the present invention provides a modular folding grille, which has the following advantages: 1. By designing the grille as a unit composed of multiple modular units, each unit consisting of at least two grille plates connected by hinges, the entire grille can be folded up, greatly reducing the product's volume when not in use, facilitating warehousing and transportation, and reducing logistics costs; when needed, it can be quickly unfolded to cover a large area.

[0016] 2. The support feet fixed to the bottom of the grid provide a uniform reference support height and form the necessary drainage gap. The key is the elastic compensation pad attached to the bottom of the support feet. It can automatically compensate for and absorb the unevenness of the ground through its own elastic deformation. This effectively avoids the swaying, warping or "seesaw" phenomenon of the grid due to uneven ground, and improves the safety of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Please see Figure 1 and combined Figure 3 This application provides a modular folding grille, comprising: multiple modular units, each modular unit consisting of at least two grille plates 1 connected by a hinge 2 arranged along its middle, allowing the unit to switch between a folded state and an unfolded state around the hinge axis; a connecting mechanism 3 disposed around the periphery of the modular unit, comprising a male connecting part 301 and a female connecting part 302, for connecting the grille plate 1 and mounting brackets 4 on both sides; and a support and leveling mechanism, comprising multiple support feet 5 fixed to the bottom of the grille plate 1 and elastic compensation pads 8 attached to the bottom of the support feet 5; the support feet 5 are used to provide a stable support height and form a drainage gap, and the elastic compensation pads 8 absorb local unevenness of the ground through their elastic deformation, thereby achieving stable leveling of the grille plate 1.

[0022] The present invention aims to provide a modular folding grille, the working principle of which is as follows: Figures 1 to 3As shown, the modular units are connected by hinges 2, and the hinges 1 can be rotated around the hinges 2 to achieve folding. Adjacent units are connected by connecting mechanisms 3 to form an overall grid structure. The modular units in the folded state are transported to the construction site and unfolded. Then, by inserting the pivot into the hinges (male connecting part 301 and female connecting part 302) of the adjacent units, they are quickly spliced ​​into a grid array of the required size. The spliced ​​array is fixed to the ground on both sides by mounting brackets 4. During the laying process, the elastic compensation pads 8 at the bottom automatically adapt to the undulations of the ground to complete the leveling. After use, the process is reversed, and it can be quickly disassembled and folded for recycling. This utility model, by designing the grid to be composed of multiple modular units, each unit being connected by at least two hinges, allows the entire grid to be folded and stored, greatly reducing the volume of the product in the non-use state, facilitating warehousing and transportation, and reducing logistics costs; when needed, it can be quickly unfolded to cover a large area. The support feet fixed to the bottom of the grid provide a uniform reference support height and form the necessary drainage gap. The key is the elastic compensation pad attached to the bottom of the support feet. It can automatically compensate for and absorb the unevenness of the ground through its own elastic deformation. This effectively avoids the swaying, warping or "seesaw" phenomenon of the grid due to uneven ground, and improves the safety of use.

[0023] Please see Figure 3 The male connecting part 301 is a hinge disposed on both sides of the grid plate 1, and the female connecting part 32 is a pivot connecting adjacent hinges. The conversion between the folded and unfolded states of multiple modular units is achieved by rotating adjacent hinges around the pivot.

[0024] Please see Figure 1 The surface of the grid plate 1 is provided with anti-slip texture 6, and multiple drainage holes 7 are drilled through the grid plate 1. The anti-slip texture design increases the friction between the sole of the foot and the surface of the grid plate, effectively preventing the risk of slipping due to water accumulation. The drainage holes can quickly drain liquid from the plate, avoiding the risk of slipping due to water accumulation, accelerating the drying process of the grid itself, reducing the possibility of water stains and microbial growth, and extending its service life.

[0025] In this embodiment of the invention, the support foot 5 and the grid plate 1 are integrally formed. The integral forming of the support foot and the grid plate brings extremely high structural integrity and strength, eliminates the risk of loosening, breakage or corrosion that may occur between the support foot and the grid plate due to the connection (such as welding, screw fixing), makes the support more robust and durable, and can withstand greater local loads. At the same time, it also reduces production and assembly steps and lowers manufacturing costs.

[0026] In this invention, the elastic compensation pad 8 is made of rubber, thermoplastic polyurethane, or silicone, and is bonded to the support foot 5 by adhesive bonding or embedded encapsulation. The use of materials such as rubber, thermoplastic polyurethane, or silicone ensures that the pad possesses excellent elasticity, wear resistance, and weather resistance; the bonding or embedded encapsulation method ensures a firm connection, preventing the pad from falling off or shifting during use, thus enabling it to perform its leveling function sustainably and stably.

[0027] Based on this, the thickness of the elastic compensation pad 8 is 5mm to 15mm. The thickness range of 5mm to 15mm is a reasonable range that takes into account both leveling ability and structural stability. It is sufficient to compensate for common ground unevenness and provide effective cushioning. At the same time, it avoids the problem of the grid being too soft and unstable due to the pad being too thick.

[0028] In this invention, hinge 2 is a one-piece molded engineering plastic pivot structure. The one-piece molded engineering plastic hinge has advantages such as light weight, corrosion resistance, fatigue resistance, and self-lubrication, avoiding the disadvantages of metal hinges that are prone to rusting and require maintenance. It is particularly suitable for humid or corrosive environments, and the one-piece molded structure ensures smooth rotation and long-term reliable execution of folding actions.

[0029] In this invention, the overall outer contour of the modular unit is rectangular. Designing the modular unit as a rectangle allows for seamless and regular planar laying during assembly, maximizing the coverage area and eliminating waste or irregular gaps. A handle 9 is provided on the outer side of the mounting bracket 4, greatly facilitating the handling, movement, and installation of each modular unit. When adjustment or storage is required, operators can easily lift the unit, avoiding the difficulty of applying force by hand or damaging the grid edges, thus improving operational efficiency and user experience.
