[0033] In addition, it should also be noted that in the description of this invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this invention can be understood according to specific circumstances.

[0034] The wiring junction box provided in this embodiment can be Figure 1 or Figure 2 the type shown with only one installation cavity, or it can also be Figure 5 the type shown with multiple installation cavities, such as Figure 1 the switch 61 is provided on the wiring junction box shown in Figure 5 one switch 61 and two sockets 62 are provided on the wiring junction box shown in. And this embodiment does not limit the number of installation cavities for electrical accessory products such as the wall switch 61 and the wall socket 62, and can be selected during implementation. That is, this wiring junction box can be of a single or multi - gang style.

[0035] When installing electrical accessory products such as the wall socket 62 and the wall switch 61, the wiring junction box provided in this embodiment will be used. During the house decoration process, generally, the wiring junction box is first embedded in the wall, and then, when the decoration is almost completed, the electrical accessory products are installed on the junction box. Generally, the electrical accessory products can be connected to the installation holes 311 on the wiring junction box through screws to achieve the fixed connection between the electrical accessory products and the wiring junction box.

[0036] Refer to Figure 3 、 Figure 4, Figure 6 and Figure 7 , the wiring base box provided in this embodiment includes a base box body 1 and at least a pair of ear members 3. At least one installation cavity is formed inside the base box body 1, and a stepped peripheral surface 11 is formed on the opening side of the installation cavity. A plurality of adjusting screws 2 are arranged on the stepped peripheral surface 11. A pair of ear members 3 are respectively arranged on opposite sides of an installation cavity of the base box body 1 and are lower than the stepped peripheral surface 11. An installation hole 311 for connecting an electrical accessory product is further formed on the ear member 3.

[0037] During decoration, the wiring base box can be first installed in the wall by means of decoration materials, and then the installation holes 311 of the electrical accessory product and the installation holes 311 on the ear member 3 are connected by screws, so that the electrical accessory product can be perfectly installed on the wall. Among them, when an electrical accessory product such as a switch 61 or a socket 62 is installed in the wiring base box, since the top end of the adjusting screw 2 supports on the bottom wall of the electrical accessory product, by pre-changing the height of the adjusting screw 2, the electrical accessory product can be made to closely adhere to the wall surface after installation or only a very thin part protrudes from the wall surface. In this way, it is not easy for the installed electrical accessory product to accumulate dust.

[0038] Exemplarily, referring to Figure 4 , a metal nut 111 is embedded at each of the four corners of the stepped peripheral surface 11 inside the base box body 1 in each installation cavity. The metal nut 111 is used to connect the adjusting screw 2. Among them, the metal nut 111 can be embedded on the stepped peripheral surface 11 of the base box body 1 to increase the connection strength between the base box body 1 and the adjusting screw 2, so that the base box body 1 is not easily damaged when the screw is tightened.

[0039] In a preferred implementation manner of the wiring base box in this embodiment, an installation groove 12 is respectively arranged on the stepped peripheral surfaces 11 on opposite sides of an installation cavity of the base box body 1, a cover plate 13 is arranged at a position corresponding to the installation groove 12 on the outer wall of the base box body 1, and a backing plate is further arranged on one side of the outer wall of the base box body 1 opposite to the cover shell. The ear member 3 is bent and forms a horizontal plate 31 and a vertical plate 32. An installation hole 311 is arranged on the horizontal plate 31, and an elastic claw 321 is further arranged on the vertical plate 32. Among them, the vertical plate 32 passes through the installation groove 12 and is clamped between the cover plate 13 and the backing plate, and the elastic claw 321 is also clamped at the bottom end of the backing plate. In this way, the ear member 3 is easily installed on the base box body 1 in a detachable manner, and the ear member 3 is easily replaced after being damaged.

[0040] The base box body 1 generally reserves a wire passing hole so that the wire can extend from the outside of the base box body 1 into the base box body 1, and then the wire is connected to the electrical accessory product. In Figure 1 , Figure 2 and Figure 5In the example, at least one wire passing hole is arranged on both the bottom wall and the side wall of the bottom box body 1, and a knock-off plate 14 is connected in the wire passing hole. In this way, the bottom box body 1 can select which surface of the wire passing hole to use according to the need of the reserved wire orientation, and then only need to break the knock-off plate 14. Among them, when the wiring bottom box is embedded, since the knock-off plate 14 closes the peripheral surface of the bottom box body 1, it can effectively prevent concrete from entering the cavity of the bottom box body 1.

[0041] In a preferred implementation manner of the wiring bottom box in this embodiment, a necking portion is further provided on the end cap of the adjusting screw 2. The wiring bottom box further includes at least a pair of support members 4, and a pair of support members 4 are respectively located on opposite sides of an installation cavity position. A connection hole 41 is further provided on the support member 4, and a notch is formed on one side of the connection hole 41 so that the necking portion of the end cap enters the connection hole 41 through the notch. And, a convex portion 42 flush with the end cap is further provided on the top surface of the support member 4. In this way, by providing the support member 4, in addition to the end face of the adjusting screw 2 supporting the bottom wall of the electrical accessory product, the convex portion 42 of the support member 4 also plays a role in supporting the bottom wall of the electrical accessory product, so as to provide a more stable and effective supporting effect on the electrical accessory product.

[0042] For example, an increase in the local thickness of the support member 4 can form the convex portion 42. In addition, the convex portion 42 on the support member 4 can also be a convex rib formed by pressing from the back surface to the front surface of the support member 4. In this way, the purpose of forming the convex portion 42 can be achieved by a more material-cost-saving method.

[0043] Figures 1 to 4 The bottom box body 1 shown in [the figure] has only one installation cavity position, and a support member 4 is respectively provided on the stepped peripheral surfaces 11 on opposite sides of the installation cavity position.

[0044] In another preferred implementation manner, the wiring bottom box can be provided with a plurality of installation cavity positions, and a vertical plate 15 is provided between adjacent installation cavity positions. Figure 6 and Figure 7 The bottom box body 1 shown in [the figure] has three installation cavity positions. A support member 4 is provided on the top surface of each vertical plate 15, and two convex ribs are formed on the support member 4. One convex rib corresponds to the installation cavity position on its left side, and the other convex rib corresponds to the installation cavity position on its right side. In this way, the support member 4 located on the top surface of the vertical plate 15 can substantially play the role of two support members 4 by providing two convex ribs, and at the same time, it is also convenient for installation. And, as can be seen from Figure 6 and Figure 7 In [the figure], an ear support member 3 is further provided on both sides of the top end of the vertical plate 15, and each installation cavity position can independently install electrical accessory products such as a switch 61 or a socket 62.

[0045] In a preferred embodiment of the wiring base box of the present embodiment, continue to refer to Figure 1 and Figure 6 , the wiring base box further includes a shielding frame member 5, which is arranged on the stepped peripheral surface 11 of the base box body 1, and a bottom periphery 51 corresponding to each installation cavity position is also formed thereon. The bottom periphery 51 is provided with through holes 511 corresponding to the adjusting screws 2, and the peripheral side walls of the shielding frame member 5 extend out of the installation opening of the base box body 1.

[0046] In this way, when embedding the wiring base box, a screwdriver can be used to operate the adjusting screw 2 through the through hole 511 on the shielding frame member 5 to adjust the shielding frame member 5 to a position flush with the wall. In effect, it is equivalent to adjusting the overall depth of the wiring base box. After installing the electrical accessory product, the electrical accessory product can be directly installed through the shielding frame member 5, so that the distance of the electrical accessory product relative to the wall can be well controlled, and at the same time, the requirement that the protruding part of the electrical accessory product from the wall is thinner can be met.

[0047] Preferably, referring to Figure 1 , the outer end of the shielding frame member 5 is further provided with an outward flange 52 for tightly attaching to the wall. In this way, it can also ensure that the protruding part of the electrical accessory product from the wall is thinner than that of the traditional installation method.

[0048] The present application relates to the technical field of the installation of electrical accessory products such as switches 61 and sockets 62, and particularly to a wiring base box. The wiring base box includes a base box body 1 and at least a pair of ear members 3. Among them, when electrical accessory products such as switches 61 or sockets 62 are installed in the wiring base box, since the top end of the adjusting screw 2 supports on the bottom wall of the electrical accessory product, by pre-changing the height of the adjusting screw 2, the electrical accessory product can be made to closely adhere to the wall surface after installation or only a very thin part protrudes from the wall surface. In this way, the installed electrical accessory product is not easy to accumulate dust.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The nouns and pronouns related to people in this patent application are not limited to specific genders.
