Description

Technical Field

[0001] This application relates to the field of PVC decorative sheets, and more particularly, to polymer PVC decorative sheets. Background Art

[0002] PVC decorative sheets have the characteristics of light weight, heat insulation, heat preservation, moisture resistance, beauty, and simple construction. There are a wide variety of specifications, colors, and patterns, which are extremely decorative. They can be used for the decoration of interior walls and ceilings, and are one of the most widely used decorative materials among plastic materials. They are usually pasted on the installation plane. In special occasions, in order to ensure flame retardancy, the PVC decorative sheets used usually adopt a composite structure, with a flame retardant material inserted between the PVC materials. However, the flame retardant material will increase the cost and weight, and the existing flame retardant materials of PVC decorative sheets cannot be flexibly disassembled and assembled, resulting in the problem of insufficient versatility.

[0003] The structure of the product can refer to a flame-retardant PVC board disclosed in the Chinese patent document with the publication number: CN213927273U. The board body has a plurality of equally spaced filler grooves integrally formed on the surface of the board body, and a flame retardant is filled in the filler grooves, and a film layer is adhered to the surface layer of the board body.

[0030] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings and in combination with embodiments.

[0031] Refer to Figures 1-4, a polymer PVC decorative sheet, comprising: a substrate 100, a decorative sheet 101, a cover 102, a flame retardant member 103, a mounting assembly 104, and a fastening assembly 105. The substrate 100 is fixedly mounted on the mounting plane. In one embodiment, the substrate 100 is provided with mounting holes, and screws are passed through the mounting holes and installed on the mounting surface. One end of the cover 102 is rotatably connected to the decorative sheet 101, and a lock 106 is provided at the other end of the cover 102. A protrusion 107 cooperating with the lock 106 is provided on the decorative sheet 101, and the cover 102 is fastened to the decorative sheet 101 through the cooperation of the lock 106 and the protrusion 107. A plurality of partitions 108 are provided on the cover 102, and a placement space is formed between the partitions 108, the cover 102, and the decorative sheet 101. The flame retardant member 103 is placed in the placement space. The flame retardant member 103 is made of a flame retardant material having the same cross-sectional shape as the placement space.

[0032] The fastening assembly 105 includes: a first buckle 109, a second buckle 110, and a connecting rod 111. The first buckle 109 is provided on the connecting portion 112, and the first buckle 109 and the third buckle 114 are respectively located on both sides of the connecting portion 112. The second buckle 110 is movably connected to the decorative sheet 101 and is used for buckling with the first buckle 109. One end of the second buckle 110 is hinged to the decorative sheet 101, so that the second buckle 110 can deflect relative to the decorative sheet 101. The connecting rod 111 is provided on the decorative sheet 101 and passes through the decorative sheet 101. One end of the connecting rod 111 is inserted into the placement space, and the other end of the connecting rod 111 is connected to one side of the second buckle 110. A sound insulation cotton 113 is provided in the placement space, and one end of the connecting rod 111 is inserted into the sound insulation cotton 113. The second buckle 110 has a first state in which it does not buckle with the first buckle 109 and a second state in which it buckles with the first buckle 109. When in the first state, the decorative sheet 101 is installed only by buckling the third buckle 114 and the fourth buckle 115, and at this time, it is convenient to disassemble the decorative sheet 101. When the second buckle 110 is in the second state, the second buckle 110 buckles with the first buckle 109 to improve the installation fastening property of the decorative sheet 101.

[0033] The mounting assembly 104 includes: side edges 116, a connecting portion 112, a third buckle 114, and a fourth buckle 115. The side edges 116 are provided on both sides of the decorative sheet 101. The connecting portion 112 is located on both sides of the substrate 100 and is in a corresponding position with the side edges 116. The third buckle 114 is fixedly provided on the connecting portion 112, and the fourth buckle 115 is fixedly provided on the side edge 116 and is used for buckling with the third buckle 114. Through the cooperation of the third buckle 114 and the fourth buckle 115, the decorative sheet 101 is installed on the substrate 100.

[0034] When the flame retardant member 103 is not placed in the placement space, the sound insulation cotton 113 is filled inside the placement space to achieve a sound insulation effect. When the flame retardant member 103 is placed in the placement space, the sound insulation cotton 113 is squeezed, and the connecting rod 111 is pushed. The connecting rod 111 pushes the second buckle 110 to engage with the first buckle 109, so that the second buckle 109 is in the second state, improving the installation firmness of the decorative piece 101.

[0035] In one embodiment, a notch 117 is formed on the decorative piece 101. The connecting rod 111 passes through the notch 117. A connecting column 118 is fixedly arranged on the connecting rod 111. A connecting hole 119 is formed on the side wall of the notch 117. The connecting column 118 is inserted into the connecting hole 119, so that the connecting rod 111 can rotate around the axis of the connecting column 118 to squeeze and deflect the second buckle 109.

[0036] In one embodiment, a boss 120 is arranged at one end of the substrate 100, and a slot 121 for inserting the boss 120 is formed at the other end of the substrate 100, which is used for connecting the PVC decorative pieces end to end, facilitating the assembly of multiple PVC decorative pieces.

[0037] The decorative piece 101 is made of polyvinyl chloride polymer material.

[0038] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles.
