Abstract
The utility model discloses a hanging hole structure of a wall-mounted rear cover, which mainly solves the problem that a hanging hole of a traditional wall-mounted rear cover is not firmly connected with a plastic expansion screw. The hanging hole structure comprises a positioning hole with a large aperture and a hanging hole with a small aperture; two backstop bulges are arranged at the transition position between the positioning hole and the hanging hole in a staggered mode. The hanging hole is integrally formed on a wall-mounted cover plate. When the cover plate with the hanging hole is connected in a wall hanging mode, the plastic expansion screw on the wall penetrates into the positioning hole, and then the cover plate is moved to enable the plastic expansion screw to slide into the hanging hole. Due to the existence of the two staggered retaining bulges, after the cover plate is hung, the plastic expansion screw cannot easily slide out and fall off, so that the whole wall-mounted rear cover is hung and connected more stably. Meanwhile, the suspension hole is formed by one-step punch forming or injection molding, so that the suspension hole is simple in overall process, low in manufacturing cost and suitable for popularization and application.

The slope that the dog was faced locating hole one end is less than the slope of hanging hole one end towards, and the plastics inflation screw can slide easily like this and hang in the hole, but can not withdraw from easily, ensures the stability that wall-hanging back lid articulates.
In this embodiment, the distance between the hanging hole resisting block 8 and the rear cover is greater than the distance between the positioning hole resisting block 7 and the rear cover; the abutting block 4 is connected with the positioning hole 1 and the hole edge of the hanging hole 2. The positioning hole 1 and the hanging hole 2 are formed in a one-step stamping or injection molding mode, and the abutting block 4 is directly formed by stamping or injection molding. The abutting block 4 can prevent the plastic expansion screw from being excessively matched with the rear cover and wearing other parts arranged in the rear cover.
In this embodiment, the positioning hole 1 has a circular-like shape with an opening, and the opening of the positioning hole 1 gradually narrows towards one end of the hanging hole; the positioning hole abutting block 7 is connected with the hole edge of the positioning hole 3 through the first connecting block 5. Correspondingly, the hanging hole 2 is in a rectangular shape with an opening, and one end of the opening of the hanging hole 2 is connected with the opening of the positioning hole 1 after passing through the backstop protrusion 3; the hanging hole abutting block 8 is connected with the hole edge of the hanging hole 2 through a second connecting block 6. After the end of the plastic expansion screw is clamped in through the positioning hole 1, the plastic expansion screw rod with the smaller diameter slides into the hanging hole through the gradually narrowed opening, and the connection mode is more stable and reliable.
Through the design, due to the existence of the two staggered retaining protrusions, after the cover plate is hung, the bolt cannot easily slide out, so that the whole wall-mounted rear cover is hung and connected more stably. Meanwhile, the suspension hole is manufactured by adopting a one-step stamping or injection molding mode, the whole process is simple, the manufacturing cost is low, and the suspension hole is suitable for popularization and application.
