Description

Technical FieldThe present invention relates to the technical field of toilet seat covers, and more particularly to a polypropylene cover with acrylic decorative plate.Prior ArtWith the rapid development of design and manufacturing technologies for toilet seat lids, higher demands are placed on the surface treatment of toilet seat lid products. In existing toilet seat lids, the decorative sheet material attached to the surface of the toilet seat lid has gained consumers' skill as a new type of decorating solution due to its unique visual effects. Although this decoration method improves the aesthetic nature of the product to a certain extent, it simultaneously has several distinct technical limitations:First, due to the inherent flexibility of the decorative sheet, it is practically impossible to completely avoid the generation of air bubbles or ragged edges during the actual installation process. These problems directly affect the flatness of the toilet seat surface and the overall appearance.Secondly, decorative films usually use back-side bonding covering the entire surface in order to ensure their adhesion. However, this design causes problems with adhesive residue when the decorative sheet is replaced, increases the difficulty of cleaning, and may damage the originally smooth surface of the toilet seat lid, which in turn impairs the aesthetic.Finally, the edges of the decorative film tend to develop discolorations or bulges due to moisture under long-term environmental exposure. This not only reduces the pleasing appearance of the toilet seat lid, but can also shorten its life.Against this background, the inventor has specifically developed a polypropylene cover with an acrylic decorative plate, and thus the present invention can be seen.Content of the Utility ModelIn order to solve the above problems, the technical solutions of the present invention are as follows:An acrylic decorative panel-equipped polypropylene cover includes a seat ring, a cover hinged to the seat ring, and an acrylic decorative panel corresponding to the outer shape of the cover, wherein a plurality of back side adhesive units are disposed on the back side of the acrylic decorative panel, and the acrylic decorative panel is detachably connected to the top surface of the cover by the plurality of back side adhesive units.Preferably, a covering trim distributed on the upper surface of the lid along the edge thereof is detachably connected, the covering trim and the acrylic trim are arranged without gaps on the upper surface of the lid, and the covering trim is a deformable flexible cover trim.Preferably, a latching groove is formed which is distributed continuously on the upper surface of the cover along its edge, and a latching block unit which is distributed continuously along its extension direction and which cooperates with the latching groove in a positive-locking manner projects on the underside of the covering decorative strip. Preferably, the locking groove comprises a first channel extending downward from the top surface of the lid and a second channel connected to the bottom of the first channel, wherein the second channel has a greater horizontal extension than the first channel, and the locking block unit comprises a connecting portion positively connected to the first channel and a locking portion positively connected to the second channel.Preferably, the two side walls of the first channel have curved projections towards each other, and the two sides of the connecting portion form curved grooves, the shape of which corresponds to the curved projections.Preferably, the edges of the latching section have curved guide slopes.Preferably, the upper surface of the covering decorative strip forms a curved transitional surface, so that an arcuate, continuous transitional surface is formed between the upper surface of the acrylic decorative plate and the side wall of the cover.Preferably, the back side adhesive units are strip-shaped, and a plurality of back side adhesive units are arranged in a unidirectional arrangement on the back side of the acrylic decorative plate.Preferably, the back side adhesive units are zigzag-shaped, and a plurality of back side adhesive units are arranged in a unidirectional arrangement on the back side of the acrylic decorative plate.Preferably, the back side adhesive units are X-shaped, and a plurality of back side adhesive units are arranged in a matrix form without gaps on the back side of the acrylic decorative sheet.Advantageous effects of the present invention are as follows:The present invention replaces the conventional decorative sheet with a rigid acrylic decorative sheet for decorating the surface of the lid and realizes a detachable connection to the lid by means of a plurality of back side adhesive units. This solution avoids the problems frequently occurring in conventional decorative films, such as air pockets, cast-on edges and adhesive residues, as a result of which the flatness of the surface and the overall aesthetic effect are significantly improved.In addition, the edge of the acrylic decorative panel is covered and protected by the covering decorative molding. This reduces the exposed area of the edge of the acrylic decorative panel, promotes the sealing between the decorative panel and the lid, and effectively prevents the ingress of moisture. This reduces discoloration or bulging at the edge and extends the service life of the product.The back side adhesive units are arranged only partially (not covering the surface), which minimizes the risk of adhesive residues during the replacement of the decorative panel. This facilitates cleaning and subsequent maintenance while ensuring that the smoothness of the surface of the lid is not impaired.The covering decorative strip is made of a flexible material and is mounted easily and stably by the latching connection between the latching groove and the latching block unit. At the same time, the upper surface of the covering trim strip has a curved transitional surface which forms a smooth, arcuate transition between the acrylic trim panel and the side wall of the cover, which further increases the aesthetic quality of the overall appearance.DESCRIPTION OF THE ACCOMPANYING DRAWINGSThe accompanying drawings are for the purpose of better understanding the present invention and form a part thereof.

It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.Embodiment 1As shown in FIGS. 1 to 6, an acrylic decorative sheet polypropylene cover which is the best embodiment of the present invention comprises a seat ring 10, a cover 20 hinged to the seat ring 10, and an acrylic decorative sheet 30 corresponding to the outer shape of the cover 20, wherein a plurality of back side adhesive units 40 are disposed on the back side of the acrylic decorative sheet 30, and the acrylic decorative sheet 30 is detachably connected to the upper surface of the cover 20 by the plurality of back side adhesive units 40. A covering decorative board 50 spread on the upper surface of the lid 20 along the periphery thereof is detachably connected, and the covering decorative board 50 and the acrylic decorative board 30 are disposed on the upper surface of the lid 20 without gaps.In this embodiment, the seat ring 10 and the lid 20 are hinged by a special toilet seat pivot structure, which is considered as prior art and will not be explained further here. The seat ring 10 and the cover 20 are designed as a polypropylene seat ring 10 and a polypropylene cover 20, respectively. The acrylic decoration panel 30 is a combined decoration panel whose surface is covered with a transparent acrylic layer and which has a decoration pattern inside. The overall contour of the acrylic decorative panel 30 is similar to the top surface of the lid 20, but is made slightly smaller than the top surface of the lid 20 to provide a mounting clearance for the covering decorative trim 50 at the edges of the top surface of the lid 20 and to form a unitary structural shape.Preferably, the covering trim 50 is a deformable flexible covering trim. In this exemplary embodiment, the covering decorative strip 50 consists of a polyurethane or silicone strip, the color of which is matched to that of the cover 20 and seat ring 10, for example white of milk, so that it can form an optically integrated surface effect with the seat ring 10 and the cover 20. The flexible nature of silicone and polyurethane also allows some deformation of the covering trim 50 which enables it to better conform to and fill the gap between the acrylic trim panel 30 and the lid 20. Preferably, as shown in FIGS. 4 and 5, a latching groove 21 is formed which is distributed continuously on the upper surface of the cover 20 along the edge thereof, and a latching block unit 51 which is distributed continuously along the direction of extension thereof and which cooperates with the latching groove 21 in a positive-locking manner protrudes on the underside of the covering decorative strip 50.Specifically, the latch groove 21 includes a first channel 22 extending downward from the upper surface of the lid 20 and a second channel 23 connected to the bottom of the first channel 22, the second channel 23 having a greater horizontal dimension than the first channel 22, and the latch block unit 51 includes a connecting portion 52 positively connected to the first channel 22 and a latch portion 53 positively connected to the second channel 23. the two side walls of the first channel 22 have protrusions curved toward each other not shown in the figures, and the two sides of the connecting portion 52 form curved grooves whose shape corresponds to the curved protrusions not shown in the figures.The first channel 22 achieves a first locking of the latching block unit 51, which can only be latched into the second channel 23 after deformation.As a result, the latch block unit 51 is fully latched and fixed in the latch groove 21, which ensures a stable mounting process of the covering decorative molding 50. The curved projections and curved grooves ensure additional stabilization of the latching connection between connecting section 52 and first channel 22.Preferably, as shown in FIG. 5, the edges of the latching section 53 have curved guide slopes.Preferably, as shown in FIG. 5, the top surface of the covering trim 50 forms a curved transitional surface such that an arcuate continuous transitional surface 54 is formed between the top surface of the acrylic trim panel 30 and the side wall of the lid 20. The arcuate continuous transition surface 54 allows for a harmonic transition between edges of the acrylic decorative panel 30 and the lid 20, which enhances the aesthetic quality of the overall appearance.Preferably, as shown in FIG. 6, in this embodiment, the back side bonding units 40 are strip-shaped, and a plurality of back side bonding units 40 are arranged in a unidirectional arrangement on the back side of the acrylic decorative plate 30. In this embodiment, the plurality of back side adhesive units 40 are arranged along a direction that is close to the axial direction of the lid 20 after the acrylic decorative plate 30 is installed, and are distributed at regular intervals in an arrangement with both sides thereof extended to the vicinity of the edge positions of the acrylic decorative plate 30, respectively.Thus, with the back side adhesive units 40 arranged in one arrangement, both the adhesive stability of the acrylic decorative panel 30 can be maintained and the damage to the surface of the lid 20 by adhesive residues can be reduced, which facilitates the replacement of the acrylic decorative panel 30 by the user.In this embodiment, 3M adhesive is used as the material for the back side adhesive units 40.Embodiment 2As shown in FIG. 7, an acrylic decorative panel polypropylene cover that is Embodiment 2 of the present invention is different from Embodiment 1 in that the back side adhesive units 40 are zigzag-shaped and a plurality of back side adhesive units 40 are arranged in a rectified arrangement on the back side of the acrylic decorative panel 30.The use of zigzag-shaped back side adhesive units 40 makes it possible to reduce the influence of adhesive residues and at the same time further enhance the adhesive stability of the acrylic decorative sheet 30.Embodiment 3As shown in FIG. 8, an acrylic decorative panel polypropylene cover that is Embodiment 3 of the present invention is different from Embodiment 1 in that the back side adhesive units 40 are X-shaped and a plurality of back side adhesive units 40 in a matrix form are arranged without gaps on the back side of the acrylic decorative panel 30.The use of X-shaped back side adhesive units 40 makes it possible to reduce the influence of adhesive residues and at the same time further enhance the adhesive stability of the acrylic decorative sheet 30.Advantageous effects of the present invention are as follows:The present invention replaces the traditional decorative sheet with a rigid acrylic decorative panel 30 for decorating the surface of the lid 20 and realizes a detachable connection to the lid 20 by means of several back-side adhesive units 40.In addition, the edge of the acrylic decorative plate 30 is covered and protected by the covering decorative molding 50. This reduces the exposed area of the edge of the acrylic decorative panel 30, promotes the sealing between the decorative panel and the lid 20, and effectively prevents the ingress of moisture. This reduces discoloration or bulging at the edge and extends the service life of the product.The back side adhesive units 40 are only partially arranged not covering the surface, which minimizes the risk of adhesive residues during the replacement of the decorative panel. This facilitates cleaning and subsequent maintenance while still ensuring that the smoothness of the surface of the lid 20 is not impaired.The covering trim 50 is made of a flexible material and is easily and stably mounted by the snap-fit connection between the snap-fit groove 21 and the snap-fit block unit 51. At the same time, the top surface of the covering trim 50 has a curved transitional surface which forms a smooth, arcuate transition between the acrylic trim panel 30 and the side wall of the lid 20, which further enhances the aesthetic quality of the overall appearance.The above explanation has exemplarily described the present utility model with reference to the drawings. Obviously, the concrete implementation of the present invention is not limited to the methods described above. Any kind of non-essential improvements made using the concept and technical solutions of the present invention, or the direct application of the concept and technical solutions of the present invention in other cases without improvements, are all within the scope of the present invention.
