Detailed Description

In order to facilitate better understanding of the skilled person, the technical solution of the present patent will be described in further detail below in connection with the specific embodiments.

As shown in FIG. 1, an adjustable bottom box convenient for flush wall surface installation of a panel comprises a rectangular bottom box 1, screw hole columns 2 arranged along the thickness direction of the bottom box and positioned at four inner corners of the bottom box, leveling studs 3 assembled in central screw holes of the screw hole columns, panel fixing seats symmetrically arranged on two opposite wall plates of the bottom box, and threading holes 5 formed in the wall plates of the bottom box. At least two wall plates of the bottom box are provided with threading holes 5, and each wall plate is provided with 1-2 threading holes. In this embodiment, the four wall plates are provided with threading holes. The outer side surface of the wall plate of the bottom box is provided with a reinforcing rib 7 so as to increase the strength and structural stability of the bottom box and prevent the bottom box from deforming.

The panel fixing seat is shown in fig. 4 and 5, and comprises a stop head 41 at the outer end part and a tenon 42 which is positioned at the inner side of the stop head and is vertical to the stop head, a triangular elastic wedge block 43 is arranged on the top surface or the bottom surface of the tenon, the front end of the elastic wedge block is a sharp corner, the rear end surface is an upright surface, and the distance a between the rear end surface of the elastic wedge block and the inner end surface of the stop head is not smaller than the thickness of the bottom box wall plate. Fig. 5 shows the arrangement of the resilient wedge 43 on the top surface of the tongue.

As shown in fig. 1, 2, 4 and 5, an adjusting hole 44 penetrating through the thickness of the tenon is formed in the tenon, a section of vertical sliding grooves 45 are symmetrically formed in the tenon and located on two sides of the adjusting hole, a sliding bearing lug 46 with an inner screw hole capable of sliding up and down along the sliding grooves is assembled in the sliding grooves, and two sides of the sliding bearing lug are clamped in the sliding grooves. As shown in fig. 3, a panel fixing seat mounting hole 6 is formed in the bottom case. The tenon 42 of the panel fixing seat is inserted into the panel fixing seat mounting hole 6 from the outer side of the bottom box until the rear end face of the elastic wedge 43 is clamped on the inner wall surface of the bottom box wall plate, and the stop head 41 is blocked on the outer side of the bottom box wall plate. The size of the panel fixing seat mounting hole 6 is matched with the tenon 42, the elastic wedge block is a plastic block with certain flexibility, and the elastic wedge block and the tenon are integrated, so that the panel fixing seat can be firmly clamped on the bottom box after being extruded and micro-deformed to pass through the panel fixing seat mounting hole 6. The resilient wedge may be replaced by other structures known in the art, such as a metal spring plate.

The panel fixing seat mounting hole 6 in this embodiment is a rectangular hole, and the tenon 42 is a strip tenon with a rectangular cross section, which is matched with the rectangular hole. The adjusting holes 44 are waist-shaped holes, so that the installation and adjustment are facilitated.

The bottom box 1 and the screw hole column 2 are of an integrated structure, and the leveling stud 3 and the panel fixing seat are detachable components. When in installation, as shown in fig. 6, the bottom box 1 is in hidden installation and is embedded into a groove reserved in the wall body 10, and the outer vertical surface of the bottom box is provided with a panel 9 of a switch or a socket. The front surface of the bottom box is open, and the back surface is a sealing plate. After the bottom box is embedded into a groove reserved in a wall body, a cable to be introduced penetrates into the box through a threading hole 5, the leveling studs 3 are rotated by means of an installation tool (such as a flat-mouth screwdriver), the outer end faces of the leveling studs at four corners are adjusted to the same vertical face, and the positions of the leveling studs are adjusted according to the thickness of a subsequently installed panel. Four leveling studs are used for supporting the panel, and when the panel is thicker, the leveling studs are screwed into the screw hole studs to a certain depth. When the panel is thinner, the leveling stud rotates shallower into the screw hole post. The outer vertical face of the adjusting bottom box is concaved inwards by 2-5 mm in the wall surface, then a panel 9 of the switch or the socket is covered, the back surface of the panel is attached to the outer end face of the leveling stud, the front surface is flush with the wall surface, finally, a mounting screw 8 is screwed into an inner screw hole of the sliding bearing lug 46 after penetrating through a mounting hole on the panel, the outer vertical face of the panel is kept flush with the wall surface, and then the whole socket or the switch is mounted. The sliding bearing lug 46 can slide up and down in the sliding groove 45, so that the mounting screw 8 can be aligned and screwed in. The panel is prior art structure, and processing has the mounting hole on the panel. The peripheral shape and the size of the panel are the same as those of the opening surface of the bottom box, and the panel can cover the bottom box and can be arranged in a groove reserved in the wall body.

The utility model can smoothly and firmly install the switch panel or the socket panel in the reserved groove of the wall body, is convenient and stable to install, can be matched with the switch panel or the socket panel with different thicknesses, enables the switch panel or the socket panel to be flush with the wall surface, and solves the problems that the panel in the prior art is covered on the wall surface, protrudes out of the wall surface and is easy to collect dust and is not attractive. Under the large environment of the current real estate development, the fine decoration delivery and the large-scale popularization and application of the digital intelligent panel, the characteristics of fine decoration, convenient construction and the like are exerted, the more attractive and practical adjustable installation of the switch and the socket is realized, and the intelligent panel has better market prospect.
