For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The specific structure of a bottom box provided by an embodiment of the utility model and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0037] by Figure 2 For reference, it should be noted that in this embodiment, the width direction refers to the a direction, the length direction refers to the b direction, the depth direction of the cavity refers to the c direction, and the width direction a, the length direction b and the depth direction of the cavity are perpendicular to each other. Figure 1-Figure 3 The bottom box 100 provided by the embodiment of the utility model includes a box body 110, and the box body 110 has a cavity for installing a functional component 200. The cavity includes a first cavity 111 and a second cavity 112 arranged in sequence along its depth direction, and the bottom of the cavity is the bottom wall of the second cavity 112, that is, the second cavity 112 is closer to the bottom of the box body 110 relative to the first cavity 111. The radial dimension of the first cavity 111 is greater than the radial dimension of the second cavity 112. The first cavity 111 is used to install a frame 210 of the functional component 200, and the second cavity 112 is used to install a functional component 220 of the functional component 200.

[0038] In detail, an outer edge convex edge 120 is provided at one end of the outer wall of the first cavity 111 away from the second cavity 112, and the side of the outer edge convex edge 120 close to the second cavity 112 is used to fit with the wall. That is to say, after the base box 100 of this embodiment is inserted into the installation cavity of the wall 2, the side of the outer edge convex edge 120 close to the second cavity 112 fits with the wall, and a convex rib 130 is provided on the side of the outer edge convex edge 120 away from the second cavity 112.

[0039] When the bottom box 100 is embedded in the wall 2, the side of the outer edge convex edge 120 close to the second cavity 112 is in contact with the wall surface, and the side of the outer edge convex edge 120 away from the second cavity 112 is provided with a convex rib 130. Therefore, during the process of scraping putty, the putty surface 3 can be made flush with the end of the convex rib 130 away from the outer edge convex rib, so that the wall opening product 1 can achieve the effect of embedded installation. In addition, the convex rib 130, the outer edge convex edge 120 and the box body 110 are integrally formed. In this embodiment, there is no need to install an additional outer frame, so that the assembly efficiency of the bottom box 100 and the wall 2 can be improved.

[0040] Furthermore, the convex rib 130 , the outer convex edge 120 and the box body 110 in this embodiment are integrally formed, which can ensure the connection strength between the convex rib 130 , the outer convex edge 120 and the box body 110 .

[0041] In detail, in the present embodiment, the direction of the rib 130 away from the outer edge convex edge 120 is parallel to the depth direction of the cavity, that is, after the box body 110 is installed in the wall 2, the side of the rib 130 is relatively perpendicular to the wall surface, thereby ensuring that it is easier for the user to scrape the putty surface 3 and ensuring that the putty on the side of the rib 130 is relatively uniform.

[0042] Of course, the above-mentioned parallelism should not be understood as parallelism in a strict sense, as long as they are roughly parallel.

[0043] In some optional embodiments, the direction of the rib 130 away from the outer edge convex edge 120 may also form an angle with the depth direction of the cavity.

[0044] Furthermore, in the present embodiment, a plurality of hollow holes 125 are provided on the outer edge convex edge 120. It can be understood that when scraping the putty surface 3, since a plurality of hollow holes 125 are provided on the outer edge convex edge 120, the putty can be buried in the plurality of hollow holes 125, thereby improving the adhesion between the putty layer and the outer edge convex edge 120 and the wall, and effectively avoiding the situation where the putty surface 3 is cracked due to insufficient adhesion.

[0045] It can be understood that the bottom box 100 of the wall socket can include multiple box bodies 110, and the multiple box bodies 110 can be arranged along the length direction. The multiple box bodies 110 can be integrated box bodies 110 or split box bodies 110. Please continue to refer to Figure 3-Figure 4For the non-side box bodies 110 among the multiple split-arranged box bodies 110, the outer edge convex edge 120 includes a first convex edge 121 and a second convex edge 122 arranged at intervals in the width direction, and the first cavity 111 has a first outer side wall and a second outer side wall arranged oppositely. It should be noted that the first outer side wall and the second outer side wall are arranged at intervals in the width direction, the first convex edge 121 is connected to the first outer side wall, and the second convex edge 122 is connected to the second outer side wall. The rib 130 is connected to at least one of the first convex edge 121 and the second convex edge 122, and the width direction and the depth direction form an angle. In detail, in this embodiment, the width direction is perpendicular to the depth direction.

[0046] It can be understood that when the box body 110 is embedded in the wall 2, the two first flanges 121 and the second flanges 122 arranged along the first interval can effectively ensure that the box body 110 is stably attached to the wall surface, so as to ensure stable assembly of the box body 110 and the wall 2.

[0047] Of course, the convex rib 130 includes a first convex rib 131 and a second convex rib 132 arranged at intervals along the width direction, the first convex rib 131 is connected to the first convex edge 121, and the second convex rib 132 is connected to the second convex edge 122. It can be understood that by providing the first convex rib 131 on the first convex edge 121 and the second convex rib 132 on the second convex edge 122, it can be ensured that the putty surface 3 on the first outer side wall and the second outer side wall of the first cavity 111 of the user is relatively flush.

[0048] For the outermost box body 110 among the multiple boxes 110, please refer to Figure 5 The outer flange 120 also includes a third flange 123 , both ends of which are connected to the first flange 121 and the second flange 122 , respectively, and the rib 130 is connected to at least one of the first flange 121 , the second flange 122 and the third flange 123 .

[0049] In detail, in this embodiment, the convex rib 130 further includes a third convex rib 133, two ends of the third convex rib 133 are respectively connected to the first convex rib 131 and the second convex rib 132, and the third seed crystal is arranged on the third convex edge 123. In other words, for the outermost box body 110 among the multiple box bodies 110, since the third convex edge 123 is also provided with the third convex rib 133, it can be ensured that the putty surface 3 on the third convex edge 123 is flush with the putty surfaces 3 of the second convex edge 122 and the first convex edge 121.

[0050] Of course, in some other optional embodiments, in the outermost box body 110 among the plurality of box bodies 110 , the first rib 131 may be provided only on the first convex edge 121 and the second rib 132 may be provided only on the second convex edge 122 .

[0051] It can be understood that, for the plurality of box bodies 110, there are two outermost box bodies 110 on both sides in the length direction, and the third convex edges 123 on the two outermost box bodies 110 are arranged opposite to each other, and similarly, the third convex ribs 133 are also arranged opposite to each other.

[0052] For details, please continue to refer to Figure 3 In some optional embodiments, the number of the box bodies 110 is three, and the three box bodies 110 are arranged at intervals along the length direction.

[0053] It should be noted that, in order to ensure the adhesion between the putty layer and the outer flange 120 and the wall, a plurality of hollow holes 125 are provided on the first flange 121 , the second flange 122 and the third flange 123 .

[0054] Of course, please refer to Figure 6 For the integrated multiple box bodies 110, the outer flange 120 includes a first flange 121, a third flange 123, a second flange 122 and a fourth flange 124 connected end to end in sequence, the first cavity 111 has a first outer side wall, a second outer side wall, a third outer side wall and a fourth outer side wall connected end to end in sequence, the first flange 121 is connected to the first outer side wall, the second flange 122 is connected to the second outer side wall, the third flange 123 is connected to the third outer side wall, the fourth flange 124 is connected to the fourth outer side wall, and the rib 130 is connected to at least one of the first flange 121, the second flange 122, the third flange 123 and the fourth flange 124.

[0055] In detail, the first outer wall and the second outer wall are spaced apart along the width direction by an interval a, the third outer wall and the fourth outer wall are spaced apart along the length direction b, and the first cavity 111 is a rectangular cavity.

[0056] In detail, in the present embodiment, the width direction is perpendicular to the length direction. Of course, this perpendicularity should not be understood as perpendicular in a strict sense, as long as they are approximately perpendicular.

[0057] In order to ensure that the putty surface 3 around the box body 110 is relatively flush, the ribs 130 include a first rib 131, a third rib 133, a second rib 132 and a fourth rib 134 connected end to end in sequence. The first rib 131 is connected to the first flange 121, the second rib 132 is connected to the second flange 122, the third rib 133 is connected to the third flange 123, and the fourth rib 134 is connected to the fourth flange 124.

[0058] Similarly, in order to ensure the adhesion between the putty layer and the outer flange 120 and the wall, a plurality of hollow holes 125 are provided on the first flange 121 , the second flange 122 , the third flange 123 and the fourth flange 124 .

[0059] In detail, the cavity includes a first cavity 111 and a second cavity 112 arranged in sequence along the depth direction. The radial dimension of the first cavity 111 is larger than the radial dimension of the second cavity 112 and is close to the outer edge convex edge 120. That is, the outer edge convex edge 120 is arranged on the side wall of the first cavity 111 away from the second cavity 112.

[0060] The bottom surface of the first cavity 111 is provided with support ribs 113 for supporting the functional component 200, that is, the functional component 200 is at least partially accommodated in the second cavity 112 and partially abuts against the support ribs 113. Under the action of the support ribs 113, the depth of the functional component 200 inserted into the second cavity 112 can be limited.

[0061] The present utility model embodiment also provides a wall opening product 1, including a functional component 200 and the above-mentioned bottom box 100, please refer to Figure 7 The functional component 200 includes a frame 210 and a functional component 220 connected to each other. The frame 210 is installed in the first cavity 111, and the functional component 220 is installed in the second cavity 112.

[0062] In detail, in order to ensure that the wall opening product 1 is flush with the putty surface 3, the side of the frame 210 away from the functional part 220 is flush with the convex rib 130. In other words, after the side of the frame 210 close to the functional part 220 abuts against the support rib 113, the side of the frame 210 away from the functional part 220 is flush with the end of the convex rib 130 away from the second cavity 112, ensuring that the wall opening product 1 does not protrude from the putty surface, ensuring the aesthetics of the product after installation.

[0063] Of course, in some other embodiments, the side of the frame 210 away from the functional part 220 is closer to the second cavity 112 relative to the rib 130 in the depth direction. That is to say, the side of the frame 210 away from the functional part 220 has a spacing with the rib 130 in the depth direction, and this spacing can facilitate the user to install the cover plate in the first cavity 111. It should be noted that the spacing between the side of the frame 210 away from the functional part 220 and the rib 130 in the depth direction is equal to the thickness of the cover plate, so as to ensure that after the cover plate is covered on the frame 210, the side of the cover plate away from the frame 210 is flush with the putty surface. It should be noted that the wall switch product 1 provided in this embodiment can be a wall switch or a wall socket, that is, the functional component 200 can be a socket or a switch, and the above-mentioned functional part 220 and the frame 210 can be integrally formed, or the functional part 220 and the frame 210 can also be a split structure.
