The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and functions of the present invention from the disclosure of the present disclosure.

It is to be understood that the structure, the proportions, the size and the like of the drawings are only used in conjunction with the disclosure of the specification for the understanding and reading of those skilled in the art, and are not intended to limit the implementation of the present invention. The qualifications are not technically meaningful, the modification or proportion of any structure Changes in the relationship or adjustment of the relationship should not fall within the scope of the technical content disclosed in this creation without affecting the effectiveness of the creation and the purpose for which it can be achieved. In the meantime, the terms "upper" and "one" as used in this specification are for convenience of description only, and are not intended to limit the scope of implementation of the creation, and the relative relationship is changed or adjusted. Under the technical content of no substantive change, it is also regarded as the scope of implementation of this creation.

Figures 2A and 2B are schematic views of the pre-embedded box 2 of the present invention. As shown in FIG. 2A, the pre-embedded box 2 includes a box body 2a and a frame assembly 2b.

The box body 2a is, for example, a cube, and has an accommodating space S formed therein, and a rectangular box body opening for connecting the accommodating space S to the outside is formed on the box body 2a, and the box body opening edge is At least one adapter portion 22 is formed, and the adapter portion 22 has a through hole 220.

The frame assembly 2b includes a frame body 20 and at least one adjusting member 21.

The frame body 20 has an opening 200 and at least one connecting portion 201 at the edge of the opening 200.

In the present embodiment, the frame body 20 is rectangular in shape corresponding to the opening of the rectangular box body of the box body 2a, and the connecting portion 201 is a rectangular sheet. For example, the connecting portion 201 is from the frame body 20. Extends and is integrally formed. Specifically, the projected area of the opening 200 of the frame body 20 is smaller than the projected area of the opening of the box body, and the outer edge size of the frame body 20 is slightly smaller than or equal to the opening size of the box body of the box body 2a.

Furthermore, the frame body 20 has a plurality of fixing holes 202, the position and number of which are eight (as shown) and the position and number of the holes 220 of the box body 2a (eight as shown). correspond. Specifically, a fixing member (not shown) such as a self-tapping screw can be used to pass through the fixing holes 202 and the through holes 220 to fix the box body 2a and the frame body 20.

Moreover, the connecting portion 201 has a plurality of positioning holes 203 for fixing an electronic device 3 (such as a switch, a smart switch, a control panel, etc.) as shown in FIG. 3A. Specifically, the position of the positioning hole 203 is aligned with the position of the opening 30 of the electronic device 3.

The adjustment member 21 is a self-tapping screw that is displaceably disposed on the connecting portion 201.

In this embodiment, the length L of the adjusting member 21 is at least greater than the distance H between the bottom edge of the frame body 20 and the top edge of the electronic device 3 (as shown in FIG. 3B), so that the adjusting member is 21 passes through the opening 30 of the electronic device 3 and the positioning hole 203 to fix the electronic device 3 to the connecting portion 201.

Furthermore, as shown in FIG. 4, a schematic perspective view of the electronic device 3 is shown, wherein the side of the electronic device 3 has a recess 31 for sliding through the connecting portion 31 when the assembly is assembled. 201 causes the electronic device 3 to enter the accommodating space S of the cartridge body 2a.

When the pre-embedded box 2 is used, as shown in FIGS. 3A to 3C, the box body 2a is first mounted to a fixed position (as in the fixed structure of the interior of the wall 9 shown in FIG. 3B, the fixing structure can be, for example, light a steel frame, and the bottom surface of the box body 2a may or may not contact the bottom wall 9a), and the frame body 20 is further Self-tapping screws (not shown, which are disposed in the fixing holes 202 and the through holes 220) are mounted on the box body 2a. Then, after completing the line configuration and other wall works for the electronic device 3 such as the smart switch, a light partition plate 9b is disposed on the bottom wall 9a, so that the frame body 20 and the box body 2a are buried in the wall surface. Inside (as shown in Figures 3C and 3B, the wall 9 is formed by the bottom wall 9a and the partition 9b). Next, a cavity 90 (for example, a rectangular hole) corresponding to the size of the opening 200 is dug in the partition plate 9b, and the connecting portion 201 is exposed outside, and the electronic device 3 is placed. Then, the adjusting member 21 is passed through the opening 30 of the electronic device 3 and the positioning hole 203 of the connecting portion 201 to fix the electronic device 3 to the frame body 20 (the partition 9b is clamped thereto) The gap between the upper portion of the frame body 20 and the lower edge of the opening 30 of the electronic device 3 can be complemented by the adjusting member 21. Finally, a panel 4 is attached to the electronic device 3.

Therefore, in the pre-embedded box 2 of the present invention, a large-sized electronic device (not shown) can be installed in the accommodating space S by using the box body 2a, and the small-sized electronic device 3 can be used by the frame assembly 2b. The opening 200 of the frame body 20 and the accommodating space S are installed, so that the convenience of use of the embedded box 2 can be improved.

Furthermore, at the time of assembly, the frame body 20 is enclosed in the wall surface together with the box body 2a, and thus is different from the conventional mounting method.

Moreover, the connecting portion 201 and the electronic device 3 are fixed by an adjusting member 21 such as a self-tapping screw, so as to facilitate freely disposing a space between the surface of the embedded box 2 and the wall surface, that is, as long as the adjusting member 21 is The length L is greater than the bottom edge of the frame body 20 after the installation is completed (as shown in FIG. 3B) and the electron The distance H between the top edges of the device 3 can be fixed. It should be understood that the distance H must include the thickness t of the partition plate 9b. Therefore, when selecting the adjusting member 21, the thickness of the partition plate 9b should be considered, thereby embedding the pre-embedded box 2 in the wall 9. The depth of the electronic device 3 can be fixed as long as the length of the selected adjusting member 21 is long enough.

In addition, the adjusting member 21 can adjust the height position of the electronic device 3, but the adjusting member 21 can be screwed between the frame body 20 (or the partition plate 9b) and the electronic device 3 as needed. The nut 23 is adapted to adjust the height position of the electronic device 3.

In summary, the pre-embedded box of the present invention, in combination with the design of the frame assembly, can accommodate electronic devices of different specifications, and the frame assembly is not only easy to manufacture and fast in production, but also saves design and manufacture of different specifications. Time and cost of electronic devices.

In addition, when installing, use an adjusting piece such as a self-tapping screw to fix it. As long as a self-tapping screw of sufficient length is selected for installation, the error distance of the embedded box from the surface of the frame body to the wall after installation can be compensated.

The above embodiments are intended to illustrate the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone who is familiar with the art may modify the above embodiments without departing from the spirit and scope of the creation. Therefore, the scope of protection of this creation should be as listed in the scope of patent application described later.
