Description

Technical Field

[0001] This utility model relates to the field of home decoration equipment, specifically to a suspended floor locking structure. Background Technology

[0002] Commonly used floating flooring typically consists of a core layer, a decorative layer, a wear layer, and a click-lock system. The click-lock system generally has tongues and grooves, and may also have a chamfered design, usually made of HDF or SPC. It is typically installed using either a flat-lock or snap-lock method, with an installation angle between 15-30 degrees, using glue or a glue-free design. However, existing flooring structures have insufficient structural strength, making them prone to cracking. For example, stress concentration at the base of the click mechanism can easily lead to breakage under temperature differences. Water resistance is poor, with water seepage at the joints causing expansion, especially if the joints are not sealed. Installation efficiency is low, requiring repeated tapping, and misalignment necessitates rework. Furthermore, it has poor stability, producing abnormal noises due to thermal expansion and contraction, and is difficult to maintain, requiring replacement of the entire floor when partially damaged.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0004] The purpose of this invention is to provide a suspended floor locking structure to overcome the aforementioned shortcomings and deficiencies of the prior art.

[0005] A suspended floor locking structure includes: a base plate, a tongue, a groove, a reinforcing structure, a sealing structure, an elastic locking mechanism, a positioning auxiliary structure, a detachable structure, and an expansion compensation structure. The tongue is connected to the long side of the base plate, the groove is connected to the short side of the base plate, and the tongue and groove are interference-fitted. The reinforcing structure is internally fitted to the base plate and connected to the root of the tongue. The sealing structure is located on the inner wall of the groove. The elastic locking mechanism is connected to the top of the tongue. The positioning auxiliary structure is connected to the edge of the splicing surface of the base plate. The detachable structure passes through the groove and connects to the tongue. The expansion compensation structure is connected to the bottom of the base plate.

[0006] The elastic locking mechanism includes a first-stage guide ramp, a second-stage locking platform, a third-stage safety groove, an elastic pin, and a return spring. The first-stage guide ramp, the second-stage locking platform, and the third-stage safety groove are adapted to the axial direction of the tenon. The elastic pin engages with the inner wall of the tenon groove, and the return spring is connected to the internal cavity of the second-stage locking platform.

[0007] Furthermore, the reinforcing structure includes: an X-shaped cross-elastic reinforcing rib and a fiberglass skeleton. The X-shaped cross-elastic reinforcing rib is connected to the substrate, and the fiberglass skeleton is pre-embedded in the direction of the tenon axis. The X-shaped cross-elastic reinforcing rib and the fiberglass skeleton have an included angle of 30°-45°.

[0008] Furthermore, the sealing structure includes a first retaining wall, a second retaining wall, and a third retaining wall, wherein the second retaining wall is connected to the outer side of the first retaining wall, and the third retaining wall is connected to the inner side of the first retaining wall, and the sealing structure is a three-dimensional sealing structure.

[0023] The elastic locking mechanism 600 includes a first-stage guide slope 610, a second-stage locking platform 620, a third-stage safety groove 630, an elastic pin 640, and a return spring 650. The first-stage guide slope 610, the second-stage locking platform 620, and the third-stage safety groove 630 are adapted to the axial direction of the tenon 200. The elastic pin 640 is engaged with the inner wall of the tenon 300, and the return spring 650 is connected to the internal cavity of the second-stage locking platform 620.

[0024] The reinforcing structure 400 includes: X-shaped cross elastic reinforcing ribs 410 and fiberglass skeleton 420. The X-shaped cross elastic reinforcing ribs 410 are connected to the substrate 100, and the fiberglass skeleton 420 is pre-embedded in the axial direction of the tenon 200. The X-shaped cross elastic reinforcing ribs 410 and the fiberglass skeleton 420 have an included angle of 30°-45°.

[0025] The sealing structure 500 includes a first barrier wall 510, a second barrier wall 520 and a third barrier wall 530. The second barrier wall 520 is connected to the outside of the first barrier wall 510, and the third barrier wall 530 is connected to the inside of the first barrier wall 510. The sealing structure 500 is a three-dimensional sealing structure.

[0026] The positioning auxiliary structure 700 includes a neodymium iron boron magnet 710 and a magnetic conductive sheet 720. The neodymium iron boron magnet 710 is embedded and connected to the long side end face of the substrate 100, and the magnetic conductive sheet 720 is connected to the short side end face of the substrate 100.

[0027] The principle of this invention is as follows: Through the coordinated work of multiple functional modules, efficient installation, stable connection, excellent sealing, and environmental adaptability of the flooring are achieved. The tongue and groove (200 and 300) employ an interference fit, ensuring the stability and firmness of the flooring joint through a tight fit, while preventing loosening and displacement. The reinforcing structure (400) consists of X-shaped cross-elastic reinforcing ribs (410) and a fiberglass skeleton (420), providing excellent mechanical strength and resistance to deformation. The reinforcing ribs disperse external forces through elastic design, while the fiberglass skeleton (420) further enhances the fracture resistance of the tongue and groove (200). The sealing structure (500) adopts a three-dimensional sealing design, consisting of three layers of retaining walls. This multi-layered protection effectively blocks the intrusion of dust, moisture, and dirt, significantly improving the flooring's waterproof and dustproof performance, making it suitable for complex environments.

[0028] The elastic locking mechanism 600 achieves automatic locking and dynamic adaptability through a multi-stage structure. The first-stage guide ramp 610 guides the tenon 200 smoothly into the mortise 300; the second-stage locking platform 620 provides initial fixation; and the third-stage safety slot 630 further locks the tenon 200 in place. The design of the elastic pin 640 and return spring 650 allows the floor to maintain a certain degree of elasticity during thermal expansion and contraction, thereby preventing damage to the joint. Furthermore, the positioning auxiliary structure 700, through the cooperation of neodymium iron boron magnets 710 and magnetic conductive sheets 720, achieves automatic alignment and rapid splicing during installation, significantly improving installation efficiency and reducing errors.

[0029] The detachable structure 800, connecting the tongue and groove 200, allows for easy disassembly and reinstallation of the flooring when needed, increasing its flexibility and maintainability. The expansion compensation structure 900 at the bottom, with its elastic design, absorbs the expansion and contraction of the flooring caused by changes in temperature and humidity, preventing warping or cracking due to environmental changes.

[0030] This utility model adds a multi-level elastic locking structure, with multiple locking latches evenly distributed along the tenon axis, which can provide multi-point locking and enhance stability. At the same time, the combination of elastic pins and return springs allows for easier alignment during installation, maintains the locked state when subjected to external force, and resets when needed.

[0031] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
