Description

Technical Field

[0001] The utility model particularly relates to a novel plastic plate for blocking wall holes. Background Art

[0002] Chinese patent publication number CN217557798U, published on October 11, 2022, discloses a plastic sheet for sealing wall holes. The sheet can be securely inserted into the wall hole via an internal plug-in structure. Cable holes, cable troughs, and a removable circular structure organize and store cables passing through the wall hole, while also providing a beautified shield for the hole and cables. Furthermore, the plastic sheet effectively prevents oversized wall holes from negatively impacting thermal insulation and sound insulation.

[0003] However, there are still some shortcomings that need to be improved, such as:

[0004] The cable trough of the plastic sheet can be torn open, allowing the sheet to be disassembled for easy wiring or rewiring. However, while being easy to tear, it can also easily cause the sheet to accidentally open after the cables are inserted. Furthermore, regardless of whether the cable trough is torn manually or accidentally opened, it has a disadvantage: the plastic sheet can easily become loose after installation.

[0005] In addition, since the outer edge of the disc structure is in a smoothly curved state, the entire plastic plate will bulge on the wall after installation. Although the volume is not large, it will affect the flatness of the wall and cause interference when placing electrical equipment. Utility Model Content

[0006] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide a method that can solve the problem in the prior art that the plastic plate cable trough cannot be restored after being torn, so that the plastic plate can be disassembled and reinstalled; and the smoothly curved part of the plastic plate can fit the wall to avoid local bulging after installation.

[0007] In order to achieve the above object, the present invention provides the following solutions:

[0008] A new type of plastic plate for sealing wall holes, including a disc structure with an edge smoothly curved toward one side, a cable hole provided in the middle of the disc structure, and a plurality of connectors provided at the edge of the cable hole. A bite structure is provided on the disc structure to facilitate opening or closing the disc structure, and a plurality of split teeth are provided on the edge of the disc structure to allow the smoothly curved portion to be spread out flatly.

[0009] Furthermore, the bite structure of the present invention includes a stripping groove provided at the edge of the disc structure and the edge of the cable hole, and a plurality of evenly arranged bite teeth are provided on the upper and lower sides of the inner wall of the stripping groove.

[0010] Furthermore, the engaging teeth in the present invention are shaped like chain teeth.

[0011] Furthermore, in the present invention, a gap is formed between every two of the engaging teeth to accommodate the opposing engaging teeth, and the engaging teeth on the upper and lower sides of the inner wall of the stripping groove can be engaged with or disengaged from each other through the gap.

[0012] Furthermore, in the present invention, a plurality of the split teeth are arranged in a circular array on the smoothly curved portion of the edge of the disc structure.

[0013] Furthermore, the split teeth in the present invention are in a shape that gradually narrows from the outside to the inside.

[0014] Furthermore, the split teeth in the present invention extend from the smoothly curved starting end of the disc structure to the outer edge of the disc structure.

[0015] In summary, the present invention has the following beneficial effects compared to the prior art:

[0016] This utility model addresses the shortcomings of a new plastic sheet for wall hole sealing, as disclosed in Chinese Patent Publication No. CN217557798U. By enabling the previously removable portion of a cable trough to be repeatedly installed and removed through a snap-fit structure, the new sheet is prevented from becoming loose after installation, making it more secure and durable. Furthermore, the provision of split teeth allows the sheet to remain flush with the wall after installation, minimizing the bulging of the disc structure after installation. The sheet conforms more closely to the wall surface, reducing interference with the placement of electrical equipment within a room. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 4The illustrated embodiment of the present invention preferably provides a novel plastic sheet for sealing wall holes, comprising a circular disc structure 1 with a smoothly curved edge, a cable hole 11 located in the center of the disc structure 1, and several connectors 12 located at the edge of the cable hole 11. The disc structure 1 is provided with a snap-fit structure 2 to facilitate opening and closing the disc structure 1, and the edge of the disc structure 1 is provided with several split teeth 3 that allow the smoothly curved portion to spread flat. Plastic sheets in the prior art: The disc structure has a smoothly curved edge that covers the wall hole, and a central cable hole is concentrically arranged with the disc structure, allowing multiple cables to pass through. Several connectors are provided, which, when inserted into the wall hole, can be tightened therein, thereby achieving installation of the plastic sheet. In this technical solution, the snap-fit structure allows the disc structure to be equipped with a tearable peeling groove that can be peeled and re-engaged. After peeling the peeling groove, the cable can be quickly and easily inserted into the cable hole. This makes it easy to assemble and disassemble, and it can be recycled. When snapped together, it is stable and durable, and the whole body will not appear loose. The split teeth are set on the smooth curved portion of the disc structure. Their function is to divide the smooth curved portion into multiple independent curved pieces. After the plastic sheet is installed, the independent curved pieces created by the split teeth can be flattened against the wall.

[0023] The bite structure 2 described in the present invention includes a stripping groove 21 provided on the edge of the disc structure 1 and the edge of the cable hole 11, and a number of evenly arranged bite teeth 22 are provided on the upper and lower sides of the inner wall of the stripping groove 21. The stripping groove divides the disc structure so that the cable hole can be opened along the stripping groove, which is convenient for loading the cable into it, or for taking out the cable at any time when it needs to be removed. The bite teeth are used to open or close the stripping groove, allowing the disc structure to maintain a stable disc shape when closed, and facilitating the installation and removal of the cable when opened. Compared with the existing technology, the disc structure can be opened or closed so that the installation and removal of the cable will not affect the stability of the disc structure, and prevent the disc structure from being deformed and becoming loose after installation.

[0024] The engaging teeth 22 of the present invention are shaped like chain teeth. The chain teeth are similar to the teeth of a zipper on clothing, and are provided with protrusions with inwardly concave edges on both sides.

[0025] In the present invention, a gap 4 is formed between each pair of engaging teeth 22 to accommodate the opposing engaging teeth 22. Multiple engaging teeth 22 on the upper and lower sides of the inner wall of the stripping groove 21 can engage or disengage with each other through this gap 4. The inwardly recessed portions of the two protruding portions form a gap into which an opposing engaging tooth can be inserted. When multiple opposing engaging teeth are engaged, the disc structure forms a stable disc shape.

[0026] In the present invention, a plurality of the split teeth 3 are arranged in a circular array on the smooth curved portion of the edge of the disc structure 1. By setting a plurality of split teeth, a plurality of independent curved pieces are formed on the periphery of the disc structure, which can be flattened on the wall after installation.

[0027] The split teeth 3 of the present invention are in a shape that gradually narrows from the outside to the inside, so as to reduce the interference between the two independent bending parts.

[0028] The split teeth 3 in the present invention extend from the smooth curved starting end of the disc structure 1 to the outer edge of the disc structure 1. The independent curved piece formed by the split teeth will not affect the deformation of the middle part of the disc structure.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
