Description

Technical Field

[0001] The utility model relates to the technical field of toilet covers, in particular to a polypropylene cover plate with an acrylic decorative plate. Background Art

[0002] With the rapid progress of the design and manufacturing technology of toilet covers, the market has put forward higher requirements for the surface treatment of toilet cover products. Among the existing toilet covers, attaching a decorative film for decoration on the surface of the toilet cover as a new decorative scheme has gradually gained the favor of consumers due to its unique visual effect.

[0003] Although this decoration method improves the aesthetics of the product to a certain extent, it is also accompanied by several significant technical limitations:

[0004] Firstly, due to the certain flexibility of the decorative film itself, it is difficult to completely avoid the occurrence of bubbles or edge warping during the actual installation process. These problems will directly affect the flatness and overall appearance of the toilet cover surface.

[0005] Secondly, the decorative film usually uses a fully covered adhesive to ensure its adhesion. However, this design will cause the problem of adhesive residue when the decorative film needs to be replaced, increasing the cleaning difficulty and possibly damaging the original smooth surface of the toilet cover, thus affecting the aesthetics.

[0006] Finally, the edges of the decorative film exposed to the environment for a long time are easily eroded by moisture and discolor or warp. This not only reduces the aesthetic degree of the toilet cover, but also may shorten its service life.

[0007] In view of this, the inventor specifically designed a polypropylene cover plate with an acrylic decorative plate, and this case was thus generated. Content of the Utility Model

It includes a seat ring 10, a cover plate 20 hinged to the seat ring 10, and an acrylic decorative panel 30 similar in shape to the cover plate 20. A number of adhesive units 40 are provided on the back of the acrylic decorative panel 30, and it is detachably bonded to the upper end surface of the cover plate 20 through a number of adhesive units 40. A decorative strip 50 distributed along its edge is detachably connected to the upper end surface of the cover plate 20. The decorative strip 50 and the acrylic decorative panel 30 are closely paved on the upper end surface of the cover plate 20.

[0037] In this embodiment, the seat ring 10 and the cover plate 20 are hinged through a special toilet lid rotating shaft structure, which is prior art and will not be elaborated here. The seat ring 10 and the cover plate 20 are a polypropylene seat ring 10 and a polypropylene cover plate 20. The acrylic decorative panel 30 is a composite decorative panel with a transparent acrylic layer covering the surface and having decorative patterns inside. The overall shape of the acrylic decorative panel 30 is designed to be similar to the upper end surface of the cover plate 20 and slightly smaller than the upper end surface of the cover plate 20, so as to reserve a certain gap at the edge of the upper end surface of the cover plate 20 for the installation of the decorative strip 50 to form an overall structural shape.

[0038] Preferably, the decorative strip 50 is a deformable flexible strip. In this embodiment, the decorative strip 50 is a polyurethane strip or a silicone strip, and its color is adjusted to be close to the colors of the cover plate 20 and the seat ring 10, such as milky white, etc., so as to be able to form an integral surface visual effect with the seat ring 10 and the cover plate 20, and the decorative strip 50 made of silicone and polyurethane materials is also convenient for a certain amount of deformation, so as to better adapt to and fill the gap between the acrylic decorative panel 30 and the cover plate 20.

[0039] Preferably, as Figure 4 shown, a continuous groove 21 is provided on the upper end surface of the cover plate 20 along its edge. The lower end of the decorative strip 50 protrudes to form a block portion 51 that is continuously distributed along its extending direction and is snap-fitted with the groove 21.

[0040] Specifically, the groove 21 includes a first channel 22 extending downward from the upper end surface of the cover plate 20 and a second channel 23 connected to the bottom of the first channel 22. The horizontal extension distance of the second channel 23 is greater than that of the first channel 22. The block portion 51 includes a connecting section 52 fitted with the first channel 22 and a buckling section 53 fitted with the second channel 23. Arc-shaped protrusions (not shown in the figure) protrude from the two side walls of the first channel 22 towards the direction of approaching each other. Arc-shaped grooves (not shown in the figure) are formed on both sides of the connecting section 52 to be adapted to the shape of the arc-shaped protrusions.

[0041] Thus, a preliminary stop for the latch portion 51 can be formed through the first channel 22, and it can be snapped into the second channel 23 only after being deformed, so that the latch portion 51 is fully snapped and limited within the card slot 21, completing the stable installation process of the decorative strip 50. Among them, the arc-shaped protrusion and the arc-shaped groove can form a more stable snap connection structure between the connecting section 52 and the first channel 22.

[0042] Preferably, as Figure 4 shown, the corners of the snap section 53 are provided with arc-shaped chamfers.

[0043] Preferably, as Figure 4 shown, the upper end surface of the decorative strip 50 forms an arc-shaped transition surface so that an arc-shaped continuous transition surface 54 is formed between the upper end surface of the acrylic decorative plate 30 and the side wall of the cover plate 20. Thus, by forming the arc-shaped continuous transition surface 54, the transition between the edge of the acrylic decorative plate 30 and the cover plate 20 can be made more harmonious, increasing the overall aesthetics.

[0044] Preferably, as Figure 5 shown, in this embodiment, the adhesive unit 40 is in a horizontal strip shape, and a plurality of adhesive units 40 are arranged in an array along the same direction on the back surface of the acrylic decorative plate 30. In this embodiment, a plurality of adhesive units 40 are arranged at equal intervals along the direction close to the axial direction of the cover plate 20 after the acrylic decorative plate 30 is installed, and both sides of them extend to the vicinity of the edge position of the acrylic decorative plate 30.

[0045] Thus, through the arrayed adhesive units 40, the stability of the bonding of the acrylic decorative plate 30 can be maintained, and the damage to the surface of the cover plate 20 caused by adhesive residue can be reduced, facilitating the replacement of the acrylic decorative plate 30 by the user.

[0046] In this embodiment, the adhesive unit 40 is selected as 3M glue. Embodiment 2

The difference from the first embodiment is that the adhesive unit 40 is in a zigzag shape, and a plurality of adhesive units 40 are arranged in an array along the same direction on the back surface of the acrylic decorative plate 30.

[0048] By using the zigzag adhesive unit 40, while reducing the influence of adhesive residue, the bonding stability of the acrylic decorative plate 30 can be further enhanced. Embodiment 3

[0049] Please refer to Figure 7, which is a polypropylene cover plate with an acrylic decorative plate as the second embodiment of the present utility model. The difference from the first embodiment is that the adhesive unit 40 is in an X shape, and several adhesive units 40 are densely paved in a matrix on the back of the acrylic decorative plate 30.

[0050] By using the X-shaped adhesive unit 40, it is possible to further enhance the bonding stability of the acrylic decorative plate 30 while reducing the influence of adhesive residue.

[0051] The beneficial effects of the present utility model are as follows:

[0052] The present utility model uses a rigid acrylic decorative plate 30 to replace the traditional decorative film to achieve the decoration of the surface of the cover plate 20, and realizes the detachable bonding with the cover plate 20 through several adhesive units 40. This method avoids common problems such as bubbles, edge warping, and adhesive residue during the installation of the traditional decorative film, and significantly improves the surface flatness and overall aesthetics.

[0053] In addition, the present utility model uses the decorative strip 50 to shield and protect the edge of the acrylic decorative plate 30, reduces the exposed area of the edge of the acrylic decorative plate 30, enhances the close fit between the decorative plate and the cover plate 20, effectively prevents water vapor from invading, thereby reducing the possibility of edge discoloration or warping, and prolonging the service life of the product.

[0054] The adhesive unit 40 adopts a partial adhesive design instead of a full coverage design, reducing the risk of adhesive residue when replacing the decorative plate, facilitating cleaning and subsequent maintenance work, and at the same time ensuring that the smoothness of the surface of the cover plate 20 is not damaged.

[0055] The decorative strip 50 is made of a flexible material, and through the snap-fit structure of the card slot 21 and the card block portion 51, it ensures the simplicity and stability of installation. At the same time, the upper end surface of the decorative strip 50 adopts an arc transition surface design, forming a smooth transition between the acrylic decorative plate 30 and the side wall of the cover plate 20, further improving the overall aesthetics.
