[0024] The utility model is further described as follows in combination with the description and specific implementation of the accompanying drawings:

[0025] As Figures 1 to 6The utility model discloses a plastic sheet piece can be fastened and blocked in the wall hole, including disc structure 1, the cable hole 11 that can insert cable, a plurality of plug -in parts 12 for connecting on the wall hole, the perforated structure 2 is arranged in the middle of disc structure 1, the connecting plate piece 3 for connecting plug -in part 12 is arranged on the perforated structure 2, the pressing structure 4 that can push the connecting plate piece 3 makes each plug -in part 12 expand outward and keep the expansion state is also arranged on the perforated structure 2. The disc structure of plastic sheet piece can be used to install on the wall hole, and the cable is passed through the cable hole to realize the storage, and the plug -in part is used for contacting the wall hole fastening plastic sheet piece. The perforated structure is arranged in the middle of disc structure and is used for accommodating connecting plate piece, plug -in part, pressing structure. The plastic sheet piece is used, first each cable is inserted into the cable hole, then all plug -in parts are inserted into the wall hole in alignment, at this moment, the whole is the loose installation state, then through the pressing structure, the connecting plate piece is pushed and curved deformation, and the plug -in part on the connecting plate piece can expand outward and top on the inner wall of the wall hole, and the stable installation is realized. And the pressing structure can keep the opening state of the connecting plate piece and plug -in piece.

[0026] The connecting plate piece 3 in the utility model is arranged between the bottom of the perforated structure 2 and the plug -in part 12. The connecting plate piece is arranged in the perforated structure and is connected with the plug -in part, and the connecting plate piece is similar to a springboard and is deformed when being stressed, therefore, the connecting plate piece at one end of the plug -in part can be curved and deformed under the action of external force, so that each plug -in part can move in the direction of outward expansion.

[0027] The connecting plate piece 3, the perforated structure 2 and the plug -in part 12 in the utility model are integrally injection molded. The integrally injection molding makes the connection of the connecting plate piece, the perforated structure and the plug -in part close, reduces the use of parts, and the stability is better during installation.

[0028] The plurality of plug -in parts 12 in the utility model are arranged around the cable hole 11 along the center of the perforated structure 2. The plurality of plug -in parts and the connecting plate piece are connected with the perforated structure in a uniform arrangement mode. The hole in the middle surrounded by the plug -in parts is the cable hole, which is used for passing through the cable hole, and since the plug -in parts expand outward during installation, the cable will not be interfered by the position after being installed in the cable hole.

[0029] The pressing structure 4 includes a plurality of column members 41 fixed on the top wall of the connecting plate member 3, and a pressing ring 42 is connected to the top of the perforated structure 2 through a plurality of connecting points 43, and the bottom wall of the pressing ring 42 abuts against the top end of the column member 41. The column member is arranged on the top wall of the connecting plate member to contact when the pressing ring is pressed down, and when the pressing ring is pressed down by hand, the connecting plate member is bent and deformed by pressing down the column member, so that each plug-in member moves outwardly and away from each other, so that the plug-in member can be fixed against the inner wall of the wall hole. The plug-in member is preferably made of plastic material with toughness, which has a certain bending when pressing against the inner wall of the wall hole, to avoid brittle fracture. The pressing ring is connected by the connecting point, so that the pressing ring has a deformable activity, and the pressing ring can be deformed from the upper side to the lower side under the force of the user.

[0030] The normal shape of the pressing ring 42 is inwardly upward and obliquely arranged towards the center. The whole pressing ring is a ring shape, and the inner edge is higher than the outer edge to form a conical ring. The pressing ring can be deformed when the user presses it, and the deformed shape is that the inner edge is lower than the outer edge.

[0031] The pressing ring 42 can be pressed downward to realize deformation and push the column member 41 to make the connecting plate member 3 bend and deform. Similar to the inflated skin, it has two states of normal and deformation, and can be maintained in any one of the two states. For this technical solution, the bending of the connecting plate member can be maintained, and the plug-in member is tightly connected to the inner wall of the wall hole.

[0032] The edge of the disc structure 1 is arranged on one side of the plug-in member 12 and is smoothly curved. The overall line is smoother, the appearance is beautiful, and the disc structure can have a slight bulge on the wall surface to adapt to the case that the wall hole is protruding.

[0033] The anti-skid convex pattern 5 is arranged on the outer wall of the plug-in member 12. When the plug-in member is tightly connected to the inner wall of the wall hole, the inner wall of the wall hole will be clamped more tightly under the action of the anti-skid convex pattern, to further avoid accidental falling out.

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the utility model

[0035] The utility model also has various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
