Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, and in particular to a PE square carpet edge anti-rolling fixing structure. Background Technology

[0002] PE carpet tiles are square-shaped carpets made of polyethylene. They are used in indoor spaces and have good wear resistance, water resistance, and easy cleaning. They can create a comfortable and beautiful floor environment and effectively enhance the interior decoration effect.

[0003] The PE carpet edge anti-curling fixing structure is a device specifically designed to prevent the edges of PE carpet tiles from curling. Its function is to firmly connect and fix the edges of the carpet tiles to the ground base structure, so that the edges of the carpet tiles remain flat during long-term use, avoiding the impact of curling on aesthetics and safety.

[0004] Traditional fixed structures use pressure strips fixed at only a few points, which cannot evenly transmit and distribute forces from different directions. This causes excessive stress on the edges of the carpet tiles, resulting in localized overload and accelerated edge curling. To solve this problem, existing technologies use a flexible buffer layer at the edges of the carpet tiles and a multi-point uniform fixing method. The flexible buffer layer disperses external forces, and the multi-point fixing ensures that the force is evenly distributed at the edges of the carpet tiles. However, in actual use, existing PE carpet tiles are fixed by adhesive. During installation, the adhesive needs to be carefully applied, resulting in low installation efficiency. When disassembling, residual adhesive is difficult to clean, which can damage the carpet tiles and the edges of the floor, wasting time and effort and increasing the cost of use.

[0020] Reference Figure 1 , Figure 2 and Figure 6 The splicing mechanism 3 includes multiple splicing dovetail blocks 301. These dovetail blocks 301 are used to engage with dovetail grooves 302 on another mounting base 201 for splicing and positioning. One side of each of the multiple splicing dovetail blocks 301 is equidistantly fixed to the front and left sides of the mounting base 201, providing a splicing interface in a specific direction. Multiple dovetail grooves 302 are equidistantly provided on the right and rear sides of the mounting base 201. These grooves provide suitable sliding space for the splicing dovetail blocks 301. The inner walls of the multiple dovetail grooves 302 are slidably connected to the outer walls of the corresponding splicing dovetail blocks 301, enabling the two mounting blocks to be joined. In the initial assembly of the base 201, multiple screws 303 are equidistantly arranged at the bottom of the inner wall of multiple dovetail grooves 302. The screws 303 are used to further tighten the splice. The outer wall of the multiple screws 303 passes through the top of the corresponding splicing dovetail block 301 and is threaded to the inner wall of the mounting base 201 to enhance the splice's firmness. The outer wall of the multiple screws 303 is slidably connected with washers 304. The washers 304 increase the contact area to distribute pressure. The multiple washers 304 are respectively attached to the top of the corresponding splicing dovetail block 301 to protect the splicing dovetail block 301 from damage by the screws 303. Specifically, the sliding connection design of the dovetail block 301 and the dovetail groove 302 makes the splicing and positioning between the installation bases 201 of the carpet tiles 1 convenient and allows for quick initial splicing. The screw 303 passes through the dovetail block 301 and is threaded to the inner wall of the installation base 201, which greatly enhances the splicing firmness and prevents the carpet tiles 1 from shifting during use. The gasket 304 protects the dovetail block 301 and distributes the pressure, ensuring that the splicing structure is stable and durable, effectively improving the laying effect and performance of the carpet tiles 1.

[0021] Reference Figure 3 , Figure 5 and Figure 6 Multiple magnetic flip covers 202 are fixedly connected to the inner side with sealing strips 4. The sealing strips 4 are used to enhance the sealing between the carpet tiles 1 and the magnetic flip covers 202, preventing dust and debris from entering the fixed structure. The bottom of the multiple sealing strips 4 is in contact with the top of the carpet tiles 1 to ensure the sealing effect. Multiple toothed grooves 5 are equally spaced around the bottom of the inner side of the mounting base 201. The toothed grooves 5 provide sliding tracks and positioning space for the toothed blocks 6. Multiple toothed blocks 6 are fixedly connected to the bottom of multiple fixing plates 203 at equal intervals. The toothed blocks 6 cooperate with the toothed grooves 5 to further enhance the connection stability between the fixing plates 203 and the mounting base 201. The outer wall of block 6 is slidably connected to the inner wall of the corresponding toothed groove 5, making the installation of the fixing plate 203 on the mounting base 201 more precise and firm. Anti-slip blocks 7 are fixedly connected to both sides of multiple positioning blocks 205. The anti-slip blocks 7 increase the friction of the positioning blocks 205 in the positioning groove 204 and prevent the positioning blocks 205 from sliding. Anti-slip grooves 8 are provided on both sides of the inner wall of multiple positioning grooves 204. The anti-slip grooves 8 and the anti-slip blocks 7 cooperate with each other to further stabilize the position of the positioning blocks 205 in the positioning groove 204. The inner wall of multiple anti-slip grooves 8 is slidably connected to the outer wall of the corresponding anti-slip blocks 7, ensuring that the positioning blocks 205 can be installed smoothly without shifting. Specifically, the sealing strip 4 enhances the seal between the carpet tile 1 and the magnetic flip cover 202, effectively preventing dust and debris from entering. The toothed groove 5 and toothed block 6 cooperate to strengthen the connection stability between the fixing plate 203 and the mounting base 201, making the installation more secure. The anti-slip block 7 and anti-slip groove 8 interact to prevent the positioning block 205 from sliding in the positioning groove 204, improving the reliability and durability of the fixing structure.

[0022] Working principle: When using the PE carpet edge anti-rolling fixing structure, first fix the mounting base 201 to the ground or base layer with multiple screws 2101 and washers 2102. Then, place the carpet 1 on the mounting base 201, align the positioning block 205 with the positioning groove 204 on the fixing plate 203 and insert it to initially determine the position of the carpet 1. Insert the limiting shaft 206 and its fixedly connected locking block 207 through the fixing plate 203 into the positioning block 205. When inserted into place, the locking ball head 2081, under the action of the spring 2082, locks into the locking groove 2083 of the locking block 207, completing the fixing of the limiting shaft 206. After the limiting shaft 206 is fixed, the positioning groove 204 on the outside of the fixing plate 203 and the positioning block 205 are fixed in place. Under the action of shaft 206, the two cannot slide against each other. The carpet tile 1 is constrained in four directions, which also completes the fixation of the carpet tile 1 and effectively prevents the carpet tile 1 from shifting and curling. Then, rotate the magnetic flip cover 202 so that its bottom is attached to the top of the positioning block 205. The bottom of the magnetic flip cover 202 is attracted to the top of the positioning block 205. When disassembling, simply pull the unlock handle 2092 to move the slide bar 2091, compress the spring 2082, and make the locking ball head 2081 disengage from the locking groove 2083. Then rotate the magnetic flip cover 202 to open it. After pulling out the limiting insert shaft 206, the carpet tile 1 can be removed from the mounting base 201. The whole process does not require the treatment of glue residue, will not damage the carpet tile and the edge of the ground, improves installation efficiency and reduces usage costs. Furthermore, when it is necessary to increase the laying area of ​​the carpet tiles 1, firstly, align the mounting base 201 with the dovetail block 301 with the dovetail groove 302 on another mounting base 201. The shape of the dovetail block 301 matches the dovetail groove 302, facilitating accurate insertion. During insertion, the dovetail block 301 slides along the inner wall of the dovetail groove 302, initially achieving the splicing and positioning of the two mounting bases 201, providing better stability and fit. Then, by sequentially passing multiple screws 303 through the splice... The top of the dovetail block 301 is threaded to the inner wall of the mounting base 201, thereby further securing the splice. The second washer 304 is placed between the second screw 303 and the splicing dovetail block 301, which can increase the contact area, distribute pressure, and prevent damage to the splicing dovetail block 301 when tightening the second screw 303. At the same time, it can also enhance the tightness and firmness of the splice, making the splicing operation of the square carpet convenient. Moreover, the structure after splicing is stable, effectively avoiding the problems of square carpet displacement and edge warping caused by poor splicing.
