Description

Technical Field

[0001] This utility model specifically relates to a pressure-resistant PVC tablecloth. Background Technology

[0002] Tablecloths are everyday household items. For environmental reasons, practical tablecloths are usually used in homes. They are generally made of plastic and come in relatively simple colors. Practical tablecloths are mostly made of PVC. PVC tablecloths are popular in my country because of their low price and good quality, and are welcomed by many families.

[0003] Traditional PVC tablecloths typically consist of a single or multiple layers of PVC material laminated onto a base fabric to achieve waterproofing and easy cleaning. However, these tablecloths are prone to denting and deformation when subjected to point pressure or heavy loads, making them difficult to spring back, and may even suffer internal structural damage resulting in indentations. Furthermore, the insufficient bonding strength between the layers in the multi-layered composite structure makes them susceptible to delamination after repeated pressure or bending, affecting their lifespan. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure-resistant PVC tablecloth.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A pressure-resistant PVC tablecloth includes a base fabric layer, a first PVC layer laminated to the upper surface of the base fabric layer, a PVC pressure-resistant layer laminated to the upper surface of the first PVC layer, a second PVC layer laminated to the upper surface of the PVC pressure-resistant layer, and a face fabric layer laminated to the upper surface of the second PVC layer; the PVC pressure-resistant layer includes a pressure-resistant layer body, trapezoidal protrusions evenly distributed on the lower surface of the pressure-resistant layer body, a lower trapezoidal insert groove formed between adjacent trapezoidal protrusions, an upper trapezoidal insert groove formed directly above the trapezoidal protrusions, and pressure-resistant buffer cavities provided on both sides of the trapezoidal protrusions.

[0007] Preferably, the pressure-resistant buffer cavity is a prismatic pressure-resistant buffer cavity.

[0008] Furthermore, the symmetrical inclined side of the rhomboid-shaped pressure-resistant buffer cavity has an inclination angle of 45°-60°.

[0009] Preferably, the upper surface of the first PVC layer is provided with upper protrusion grooves corresponding to the embedded trapezoidal protrusions at equal intervals, and an upper embedding protrusion embedded in the lower trapezoidal groove is formed between the two upper protrusion grooves.

[0010] Preferably, the lower surface of the second PVC layer is equidistantly formed with lower insert protrusions that are embedded in the upper trapezoidal insert groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The pressure-resistant buffer cavity in the PVC pressure-resistant layer is a prismatic pressure-resistant buffer cavity. Through a unique pressure conversion mechanism from vertical force to bidirectional diagonal extrusion, it can efficiently absorb the initial impact energy and prevent stress concentration. At the same time, it provides rigid support when under deep pressure, and the trapezoidal protrusions themselves also increase the strength of the pressure-bearing points.

[0013] 2. The upper convex groove and the upper convex strip cooperate with the trapezoidal convex strip and the lower trapezoidal groove, and the lower convex strip cooperates with the upper trapezoidal groove, which can firmly anchor the composite layers together, greatly improve the interlayer bonding strength and the ability to resist peeling, and greatly extend the service life of the tablecloth under repeated pressure and bending.

[0014] 3. The rhomboid-shaped pressure-resistant buffer cavity can effectively disperse pressure and promote elastic recovery after being compressed, reducing the formation of permanent indentations. Moreover, the trapezoidal composite embedding method can enhance the rigidity of the overall structure and prevent large deformations. Attached Figure Description

However, the embodiments are not intended to limit the present invention.

[0018] Example

[0019] A type of pressure-resistant PVC tablecloth, such as Figure 1-2 As shown, it includes a base fabric layer 1, a first PVC layer 2 laminated to the upper surface of the base fabric layer 1, a PVC compression-resistant layer 3 laminated to the upper surface of the first PVC layer 2, a second PVC layer 4 laminated to the upper surface of the PVC compression-resistant layer 3, and a top fabric layer 5 laminated to the upper surface of the second PVC layer 4.

[0020] The PVC compression-resistant layer 3 includes a compression-resistant layer body 31, trapezoidal protrusions 32 evenly distributed on the lower surface of the compression-resistant layer body 31, a lower trapezoidal insert groove 33 opened between adjacent trapezoidal protrusions 32, an upper trapezoidal insert groove 34 opened directly above the trapezoidal protrusions 32, and compression-resistant buffer cavities 35 provided on both sides of the trapezoidal protrusions 32.

[0021] In this embodiment, the pressure-resistant buffer cavity 35 is a prismatic pressure-resistant buffer cavity, and the symmetrical hypotenuse of the prismatic pressure-resistant buffer cavity 35 has an inclination angle of 45°-60°.

[0022] It should be further explained that, since the pressure-resistant buffer cavity 35 is a rhomboid pressure-resistant buffer cavity, and the symmetrical inclined side structure inside the cavity can convert the vertical pressure into bidirectional diagonal extrusion force, avoiding stress concentration, the short diagonal of the rhombus is compressed when under pressure, the inclined side deforms rapidly to absorb the initial impact, and the long diagonal extends to resist large deformation, providing high-strength support.

[0023] The upper surface of the first PVC layer 2 is provided with upper protrusion grooves 21 corresponding to the embedded trapezoidal protrusions 31 at equal intervals, and an upper protrusion 22 embedded in the lower trapezoidal groove 33 is formed between the two upper protrusion grooves 21.

[0024] The lower surface of the second PVC layer 4 is equidistantly formed with lower insert protrusions 41 that are embedded in the upper trapezoidal insert groove 34.

[0025] It should be further explained that the upper convex groove 21 and the upper convex 22 cooperate with the trapezoidal convex 32 and the lower trapezoidal groove 33, and the lower convex 41 cooperates with the upper trapezoidal groove 34, which can firmly anchor the composite layers together, greatly improve the interlayer bonding strength and the ability to resist peeling, and greatly extend the service life of the tablecloth under repeated pressure and bending.
