Description

Technical Field

[0001] This utility model relates to the field of PVC flooring technology, specifically to a PVC flooring edge sealing structure. Background Technology

[0002] PVC flooring is a multi-layer composite roll or sheet flooring made of polyvinyl chloride resin as the main raw material through calendering, extrusion or coating processes. The surface is covered with a wear-resistant layer and a printed layer, and the bottom often has a glass fiber stabilizing layer or a foam cushioning layer. It has the characteristics of being non-slip, waterproof, flame retardant, easy to clean, rich in colors and patterns, and quick to install. It is widely used in hospitals, schools, shopping malls and homes. After the sheet PVC flooring is spliced, it needs to be sealed at the edges. The traditional method is to directly squeeze silicone or polyurethane sealant into the seam after the two boards are spliced ​​together, and use the elasticity and adhesion of the cured adhesive to seal the gap and prevent moisture and dust from entering. While traditional methods can achieve a sealing effect, this sealing method requires a second sealing process after installation. This construction process increases the operation steps and thus significantly reduces construction efficiency. Therefore, to address the above problems, a PVC floor edge sealing structure is proposed. Utility Model Content

[0014] 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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A PVC flooring edge sealing structure includes a board body 1. Two adjacent sidewalls of the board body 1 are male ends, and two other adjacent sidewalls of the board body 1 are female ends. A positioning component 2 is provided between the male and female ends. First sealing components 3 are provided on the upper and lower sides of the positioning component 2. A second sealing component 4 is provided between the male and female ends. The first sealing component 3 includes a first sealing groove 31 and a second sealing groove 32. The first sealing groove 31 and the second sealing groove 32 are longitudinally symmetrically arranged on the male and female ends of the board body 1. The first sealing groove 31 and the second sealing groove 32 are of the same specifications and are positioned correspondingly. A sealing strip 33 is provided between the first sealing groove 31 and the second sealing groove 32.

[0017] As a further implementation of this solution, the positioning component 2 includes multiple sets of positioning heads 21 and positioning slots 22. The multiple sets of positioning heads 21 and positioning slots 22 are arranged in a regular array. The positioning heads 21 are fixedly connected to the outer side of the male end of the plate 1, and the positioning slots 22 are opened on the outer side of the female end of the plate 1. The number of positioning heads 21 and positioning slots 22 are equal, their positions are corresponding, and their specifications are matched. The positioning heads 21 are arrow-shaped with a wider top and a narrower bottom and forked sides. A return spring 23 is fixedly connected to the inner wall of the forked part of the positioning head 21. The above configuration can provide good positioning capability between the two plates 1 during splicing and prevent positional displacement between the two plates 1 during splicing.

[0018] As a further implementation of this solution, the sealing strip 33 has a dumbbell-shaped cross-section with rounded protrusions at both ends and a flat middle section. The two ends of the sealing strip 33 are respectively connected to the first sealing groove 31 and the second sealing groove 32 with an interference fit. The above configuration can provide good sealing ability after the two plates 1 are spliced ​​together, so as to ensure the performance and service life of the plates 1.

[0019] As a further implementation of this solution, the second sealing assembly 4 includes a compression protrusion 41 and a pressure-receiving groove 42. The compression protrusion 41 is fixedly connected to the outer side of the male end of the plate 1, and the pressure-receiving groove 42 is opened on the outer side of the female end of the plate 1. The compression protrusion 41 and the pressure-receiving groove 42 are equal in number, corresponding in position, and matched in specifications. The inner and outer sides of the pressure-receiving groove 42 are provided with a matching protective baffle 43. The inner cavity of the pressure-receiving groove 42 is provided with a sealing capsule 44, which is hollow inside, and the inner cavity of the sealing capsule 44 is filled with... The sealing capsule 44 is filled with sealant, and the two ends of the sealing capsule 44 are symmetrically provided with sealant discharge covers 45. A first sealing channel 46 is horizontally opened at the center of the outer side of the male end of the plate 1, and a second sealing channel 47 is horizontally opened at the center of the outer side of the female end of the plate 1. The second sealing channel 47 is connected to the pressure groove 42. The first sealing channel 46 and the second sealing channel 47 are positioned correspondingly and matched in specifications. The above configuration can automatically squeeze out sealant after the two plates 1 are spliced ​​together, thus improving the sealing effect after the two plates 1 are spliced ​​together.

[0020] Workflow: When the plates 1 are spliced ​​together, the male end of one plate 1 is first placed on the female end side of the other plate 1, and the male end of one plate 1 is brought close to the female end of the other plate 1. At this time, the positioning component 2 can provide good positioning capability between the two plates 1 during splicing, preventing positional misalignment between the two plates 1 during splicing. The positioning head 21 on the male end side of one plate 1 will be inserted into the positioning slot 22 opened on the female end side of the other plate 1. The forked expansion ends on both sides of the positioning head 21 will deform inward due to the pressure of the inner wall of the positioning slot 22, and at the same time, it will compress the return spring 23. 23 uses its own rebound force to drive the forked expansion ends on both sides of the positioning head 21 to expand and reset, so that the positioning head 21 is locked in the positioning slot 22. One end of the sealing strip 33 in the first sealing assembly 3 will be pre-interfered and connected to the first sealing groove 31 opened on the male end side of a plate 1. While the positioning assembly 2 positions the two plates 1, the other end of the sealing strip 33 will be inserted into the second sealing groove 32 opened on the female end side of another plate 1 and interfered. The first sealing assembly 3 can provide good sealing ability between the two spliced ​​plates 1 to ensure the use effect and service life of the plates 1. While positioning component 2 positions the two plates 1, the extrusion protrusion 41 on the male end side of one plate 1 extrudes the protective baffle 43 and inserts it into the pressure-bearing groove 42 on the female end side of the other plate 1. The protective baffle 43 provides a certain degree of protection for the sealing capsule 44 inside the pressure-bearing groove 42, preventing accidental breakage during transportation. After the extrusion protrusion 41 is inserted into the pressure-bearing groove 42, it will extrude pressure on the sealing capsule 44. The increased pressure on the sealing capsule 44 forces the glue discharge cover 45 to open, causing the sealant filling the sealing capsule 44 to be squeezed out. When the male end of plate 1 is fully attached to the female end of another plate 1, the first sealing channel 46 and the second sealing channel 47 will adhere to each other to form a complete channel. The extruded sealant will flow in the complete channel and fill the entire channel. The sealant can be initially cured within five minutes and completely cured after twenty-four hours. Therefore, the second sealing component 4 can improve the sealing effect between the two plates 1. Furthermore, this method eliminates the need for a sealing process after the two plates 1 are installed. This construction process reduces the number of steps and thus greatly improves construction efficiency.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
