Description
Technical Field
[0001] This utility model relates to the field of interlocking carpet technology, specifically to a snap-on quick-installation interlocking carpet. Background Technology
[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass, or chemical synthetic fibers, through hand or mechanical processes of weaving, tufting, or spinning. Carpets are the most common floor decoration and protection materials in home decoration, office layout, or temporary event venue construction.
[0003] In existing technologies, carpets rely on adhesive or heavy objects to press the edges during installation and splicing. This not only requires multiple people to precisely align the edges of the floor, consuming significant manpower, but also requires 4-8 hours for the adhesive to cure, during which time the area is completely unusable, greatly extending the construction period. More importantly, if there are minor unevenness issues on the floor, such as tile joints or warped wood flooring edges, the adhesive can easily create localized hollow areas, causing the carpet edges to frequently lift later. This necessitates repeated disassembly and repair, further increasing maintenance and time costs, resulting in extremely low overall installation efficiency. Even when using interlocking carpets, the snaps on each carpet edge only use a single groove and groove for alignment, lacking auxiliary positioning and error compensation structures. This makes it easy for deviations to occur during splicing, and as the number of spliced pieces increases, the errors accumulate, eventually leading to obvious wavy protrusions on the surface of the spliced carpet. This not only damages the overall aesthetics of the floor decoration but also creates obstacles for walking on, affecting comfort. Utility Model Content
[0004] The purpose of this invention is to provide a snap-on type of quick-installation interlocking carpet to solve the problems mentioned in the background art, which are that traditional whole carpets rely on glue or heavy objects for fixing, require multiple people to work together to align them, wait for the glue to cure, have long periods of idle space and high labor costs, and are prone to hollowing and lifting due to slight unevenness of the ground, requiring repeated repairs; and that snap-on interlocking carpets rely on a single groove and protrusion for alignment, lacking auxiliary positioning and error compensation structures, making it easy for the splicing to be misaligned and the error to accumulate with the number of pieces, eventually causing the carpet surface to have a wavy bulge, which affects both the appearance and the comfort of walking on it.

[0017] 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.
[0018] Please see Figure 1-5 This utility model provides an embodiment of a snap-fit quick-installation interlocking carpet, including a support frame 1, a carpet assembly mounted on the support frame 1, a first fixing strip 21 and a second fixing strip 22 fixedly connected to the support frame 1, an alignment component and an installation block 23 detachably mounted on the second fixing strip 22, an installation component mounted on the installation block 23, an insert block 27 fixedly connected to one side of the installation block 23, a semi-circular locking block 28 slidably connected to the insert block 27, a limiting disc 29 fixedly connected to the inner side of the semi-circular locking block 28, and an elastic unit mounted on the insert block 27. The insert block 27 is detachably mounted on the first fixing strip 21 of another set of support frames 1, the limiting disc 29 is slidably connected to the insert block 27, the semi-circular locking block 28 is locked onto the first fixing strip 21 of another set of support frames 1, and the elastic unit is used to connect the semi-circular locking blocks 28 on both sides to the limiting disc 29. The disc 29 moves outward, and the installation component is used to install or remove the installation block 23. The alignment component is used to align the two sets of support frames 1 when splicing them. Through the cooperation of the insert block 27, the semi-circular locking block 28, the limiting disc 29 and the elastic unit, the semi-circular locking block 28 can be quickly locked into the slot of the first fixing strip 21 of the other set of support frames 1, realizing the rapid splicing between support frames 1 without relying on glue or multiple people to align, which greatly improves the efficiency of modular carpet installation and shortens the construction cycle. The installation component allows for convenient installation or removal of the installation block 23. Combined with the detachable design of the alignment component and the installation block 23 on the outermost second fixing strip 22, it not only facilitates the maintenance or replacement of local carpet components in the later stage, reducing maintenance costs, but also allows the removal of excess parts after installation, further improving the overall aesthetics of the carpet installation.
[0019] Please see Figure 5A further solution based on this embodiment is as follows: the first fixing strip 21 has a slot at the corresponding position of the insert 27. The insert 27 is detachably installed in the slot of the first fixing strip 21. By opening a slot on the first fixing strip 21 that is compatible with the insert 27, a clear positioning guide can be provided for the installation of the insert 27, avoiding lateral or longitudinal displacement of the insert 27 during the splicing process, ensuring that the insert 27 can be accurately embedded in the first fixing strip 21, thereby ensuring the positional accuracy when splicing the two sets of support frames 1, laying a stable foundation for the subsequent snapping of the semi-circular snap-fit block 28, and reducing splicing rework caused by misalignment of the insert 27.
[0020] Please see Figure 5 A further solution based on this embodiment is as follows: one end of the semicircular locking block 28 is set to a semicircular shape, the first fixing strip 21 contacts the arc end of the semicircular locking block 28, and the first fixing strip 21 has a slot at the corresponding position of the semicircular locking block 28. The semicircular locking block 28 is locked into the slot of the first fixing strip 21. By setting one end of the semicircular locking block 28 to a semicircular shape, when the two sets of support frames 1 are close to each other, the semicircular end can form a smooth contact with the first fixing strip 21, reducing the frictional resistance during splicing and allowing the semicircular locking block 28 to slide more smoothly into the slot position. In addition, with the slot on the first fixing strip 21, the semicircular locking block 28 can be accurately locked in and locked, avoiding relative displacement of the two sets of support frames 1 after splicing, improving the overall stability of the carpet after splicing, preventing the splicing from loosening due to vibration or stepping during later use, and improving the convenience of disassembly by forming a smooth contact between the semicircular end and the first fixing strip 21.
[0021] Please see Figure 5 A further solution based on this embodiment is as follows: The elastic unit includes a spring 210 fixedly connected between the semicircular locking block 28 and the insert block 27. The spring 210 is used to move the limiting discs 29 on both sides and the semicircular locking block 28 outward in a linear motion. By setting the spring 210 between the semicircular locking block 28 and the insert block 27, the spring 210 can continuously provide an outward elastic push force to the semicircular locking block 28 and the limiting disc 29. When the insert block 27 is inserted into the slot of the first fixing strip 21, the spring 210 can automatically push the semicircular locking block 28 outward to unfold, so that the semicircular locking block 28 can quickly lock into the slot of the first fixing strip 21 without manual pressing or adjustment, simplifying the splicing operation steps; at the same time, the elastic effect of the spring 210 can keep the semicircular locking block 28 and the slot tightly fitted. Even if slight wear occurs after long-term use, the spring 210 can compensate for the wear and maintain the locking stability.
[0022] Please see Figure 4A further embodiment of this solution is as follows: the mounting assembly includes a first threaded rod 24 rotatably connected to the mounting block 23, a knob 25 fixedly connected to one end of the first threaded rod 24, and a fixing plate 26 fixedly connected to the center of the first threaded rod 24. The fixing plate 26 is rotatably connected to the mounting block 23. The first threaded rod 24 is threadedly connected to the second fixing strip 22. The mounting block 23 is mounted on the second fixing strip 22. The knob 25 is used to rotate the first threaded rod 24. By rotating the first threaded rod 24 through the knob 25, the first threaded rod 24 is engaged with the first threaded rod. The threaded connection between the first threaded rod 24 and the second fixing strip 22, as well as the limiting effect of the fixing plate 26 on the mounting block 23, can easily achieve the fixing or separation of the mounting block 23 and the second fixing strip 22: turning the knob 25 clockwise can screw the first threaded rod 24 into the second fixing strip 22 and firmly insert the mounting block 23 into the square groove for fixing; turning the knob 25 counterclockwise can remove the mounting block 23. The whole process does not require special tools, and the operation is simple and convenient, which facilitates the maintenance or replacement of components such as the mounting block 23 and the insert 27 in the later stage, reducing the difficulty of maintenance.
[0023] Please see Figure 4 A further solution based on this embodiment is as follows: the second fixing strip 22 has a square groove at the corresponding position of the mounting block 23, and the mounting block 23 is set at the square groove of the second fixing strip 22. By opening a square groove on the second fixing strip 22, the square groove can adapt and limit the shape of the mounting block 23, preventing the mounting block 23 from rotating or shifting on the second fixing strip 22, ensuring that the mounting block 23 always maintains the correct position and posture after installation, thereby ensuring that the insert block 27, semi-circular locking block 28 and other components on the mounting block 23 can accurately correspond to the first fixing strip 21; at the same time, the structure of the square groove can increase the contact area between the mounting block 23 and the second fixing strip 22, improve the stability of the connection between the two, and prevent the mounting block 23 from loosening due to external force collision.
[0024] Please see Figure 3 A further solution based on this embodiment is as follows: the alignment component includes a second threaded rod 31 threadedly connected to the second fixing strip 22, a tapered positioning pin 32 fixedly connected to one end of the second threaded rod 31, and an alignment hole 33 opened on the first fixing strip 21. The tapered positioning pin 32 is detachably installed at the alignment hole 33. The second threaded rod 31 is used to disassemble and install the tapered positioning pin 32. Through the cooperation between the tapered positioning pin 32 and the alignment hole 33 on the first fixing strip 21, the guiding nature of the tapered structure allows the two sets of support frames 1 to be quickly aligned during splicing without repeated position adjustments, greatly shortening the alignment time and improving splicing efficiency. At the same time, the tapered positioning pin 32 can be easily disassembled and installed through the second threaded rod 31. After splicing is completed, the tapered positioning pin 32 can be removed to prevent it from being exposed and affecting the overall aesthetics of the carpet. It can also be quickly disassembled and reused when the splicing position needs to be readjusted, improving the reusability of the component.
[0025] Please see Figure 2 A further embodiment of this solution is as follows: the carpet assembly includes a waterproof pad 41 fixedly connected to the support frame 1 on one side, a sound-absorbing pad 42 fixedly connected to the other side of the waterproof pad 41, a Velcro 43 fixedly connected to the side of the sound-absorbing pad 42 away from the waterproof pad 41, a Velcro 44 attached to the Velcro 43, and a skin-friendly pad 45 fixedly connected to the side of the Velcro 44 away from the Velcro 43. The Velcro 43 and Velcro 44 are used to install and remove the skin-friendly pad 45. The waterproof pad 41 can prevent ground moisture from rising upwards. The sound-absorbing pads 42 and 45 are prevented from becoming moldy due to moisture, thus extending the lifespan of the carpet assembly. The sound-absorbing pads 42 absorb some of the noise in the environment, improving the quietness of the indoor environment and enhancing user comfort. At the same time, the skin-friendly pads 45 can be quickly installed and removed through the adhesive of the Velcro 43 and Velcro 44. When the skin-friendly pads 45 are dirty or worn, they can be directly torn off for replacement or cleaning without disassembling the entire carpet assembly, reducing maintenance costs. Different styles of skin-friendly pads 45 can also be replaced as needed, increasing the flexibility of use.
[0026] Working principle: When multiple sets of carpets need to be spliced, the tapered positioning pin 32 is first installed onto the second fixing strip 22 using the second threaded rod 31. Then, the tapered positioning pin 32 is aligned with the alignment hole 33 on the first fixing strip 21 of the other set of support frames 1 and inserted to quickly calibrate the relative position of the two sets of support frames 1 and avoid splicing misalignment. After alignment, the two sets of support frames 1 are pushed closer to each other, so that the insert 27 on one side of the mounting block 23 installed in the square groove of the second fixing strip 22 is slowly inserted into the slot of the first fixing strip 21. During the insertion process, the first fixing strip 21 contacts and squeezes the arc end of the semi-circular locking block 28. The semi-circular locking block 28 drives the limiting plate 29 to slide inward toward the insert 27, while compressing the spring 210 of the elastic unit. When the insert 27 is fully embedded in the slot, the spring 210 releases the elastic thrust, pushing the limiting plate 29 and the semi-circular locking block 27 into the slot. Move 8 outwards to precisely engage the semi-circular locking block 28 into the slot of the first fixing strip 21, achieving a stable splicing of the two sets of support frames 1 without relying on glue or multiple people working together; then, through the adhesive cooperation of the Velcro 43 and Velcro 44, install the skin-friendly soft pad 45 onto the sound-absorbing soft pad 42 to form a single carpet structure that can be used independently; if it is necessary to change the carpet surface style, simply tear off the skin-friendly soft pad 45 and replace it with a new skin-friendly soft pad 45 through the Velcro 43 and Velcro 44. After splicing, the tapered positioning pin 32 can be removed through the second threaded rod 31, and then the first threaded rod 24 can be rotated through the knob 25 of the installation component. By utilizing the threaded engagement between the first threaded rod 24 and the second fixing strip 22, the installation block 23 can be removed from the square slot, avoiding its exposure and affecting the overall aesthetics. The whole process is convenient to operate, taking into account both installation efficiency and flexibility of later maintenance.
