[0002] During the installation of sanitary ware products, an embedded box may be used. The embedded box is installed inside a wall, and the inside of the embedded box can accommodate items such as valves, pipelines, wires, etc. The embedded box mainly includes a box body and a face cover. In the prior art, the box body and the face cover of some embedded boxes are connected by a snap connection method. During the actual installation of the embedded box, the installer may need to cut off a part of the box body according to the situation of the construction site to prevent the part of the embedded box protruding outside the wall from being too much. However, due to possible errors during the cutting of the box body, all snap components may not be effectively snapped during the subsequent assembly process of the face cover and the box body. This will result in an insecure connection between the face cover and the box body, thereby causing the face cover to be easily loosened. Summary of the Utility Model

[0033] Figure 1 The embedded box 100 of an embodiment of the present utility model is shown. Figure 2 It is an exploded view of the embedded box 100. Figure 3 and Figure 5 Both show a part of the embedded box 100. The embedded box 100 includes a box body 101, a face cover 102 and a clamping component. Among them, there are multiple (at least two) clamping components, and each clamping component includes a first connecting body 109 and a second connecting body 110 that can be clamped with each other. In this embodiment, the first connecting body 109 is connected to the face cover 102 (as shown in Figure 5 ), and the first connecting body 109 is connected to the box body 101 (as shown in Figure 3 ). In some other embodiments, the positions of the first connecting body 109 and the second connecting body 110 can also be interchanged, that is, the first connecting body 109 is connected to the box body 101, and the second connecting body 110 is connected to the face cover 102. The first connecting body 109 and the face cover 102 can be integrally formed, and the second connecting body 110 and the box body 101 can also be integrally formed.

[0034] As Figure 2 shown, the box body 101 is provided with an inner cavity 106, and the inner cavity 106 includes an opening 107, and the opening 107 is located at the top end of the inner cavity 106. As Figure 3As shown in the figure, the box body 101 includes a bottom plate 112 and a plurality of side plates 111. The plurality of side plates 111 surround the edge of the bottom plate 112, so that the side plates 111 and the bottom plate 112 jointly enclose an inner cavity 106. The bottom plate 112 is arranged opposite to the opening 107, and the top edges of the plurality of side plates 111 jointly enclose the opening 107. The inner cavity 106 can accommodate items such as valves, pipelines, and cables. After the face cover 102 and the box body 101 are assembled with each other, the face cover 102 will cover the opening 107 to prevent the items accommodated in the box body 101 from being exposed. As Figure 6 shown, the box body 101 of the embedded box 100 can be embedded inside the wall body 123, and the face cover 102 can be exposed outside the wall body 123 for the user to disassemble the face cover 102. As Figure 2 shown, the face cover 102 can be provided with a first through hole 105, and the first through hole 105 communicates with the inner cavity 106. The first through hole 105 can allow pipelines and cables to pass through. Similarly, as Figure 2 shown, at least one side plate 111 is provided with a second through hole 104, and the second through hole 104 can also allow pipelines and cables to pass through. A sleeve 103 can also be installed in the first through hole 105, and the sleeve 103 is used to protect the pipeline or cable so as to prevent the hole wall of the first through hole 105 from scratching the pipeline or cable.

[0035] As Figure 7 、 Figure 8 or Figure 9 shown, the first connecting body 109 includes a plurality of first clamping parts 120, and the plurality of first clamping parts 120 are spaced apart along the orientation of the opening 107. In this embodiment, the opening 107 is arranged upward (as Figure 2 shown), the orientation of the opening 107 is the direction from bottom to top. Correspondingly, the plurality of first clamping parts 120 are spaced apart from bottom to top. A clamping groove 124 is formed between every two adjacent first clamping parts 120, and the first connecting body 109 is provided with a plurality of clamping grooves 124. The second connecting body 110 includes a second clamping part 118, and the second clamping part 118 can be clamped in the clamping groove 124 (as Figure 8 shown), so as to prevent the face cover 102 from moving along the orientation of the opening 107.

[0036] For the multiple clamping components of the embedded box 100, a part of the clamping components are the first components 121, and another part of the clamping components are the second components 122. For example, in Figure 6 , the first components 121 are located on the left side of the inner cavity 106, and the second components 122 are located on the right side of the inner cavity 106. Another example, as Figure 3 shown, D 1 、D 2 、D 3The second connectors 110 in these three regions belong to the second component 122, and the remaining three second connectors 110 belong to the first component 121; as Figure 5 shown, E 1 、E 2 、E 3 The first connectors 109 in these three regions belong to the second component 122, and the remaining three first connectors 109 belong to the first component 121.

[0037] In this embodiment, the first component 121 and the second component 122 satisfy the following conditions: the first latching portions 120 of the first component 121 are aligned with the first latching portions 120 of the second component 122 one by one, and the second latching portions 118 of the first component 121 are staggered from the second latching portions 118 of the second component 122. This condition helps to reduce the risk that all latching components are not in the latching state.

[0038] The meaning of the above conditions will be explained below. Figure 9 The first connectors 109 of the first component 121 and the first connectors 109 of the second component 122 are shown. In Figure 9 , the leftmost first connector 109 belongs to the first component 121, and the first latching portion 120 on the leftmost first connector 109 (i.e., the leftmost column of first latching portions 120) belongs to the first component 121. The rightmost first connector 109 belongs to the second component 122, and the first latching portion 120 on the rightmost first connector 109 (i.e., the rightmost column of first latching portions 120) belongs to the second component 122. As Figure 9 shown, the first latching portions 120 of the first component 121 and the first latching portions 120 of the second component 122 are the same in terms of shape, size, and quantity. If the plane where the opening 107 is located is denoted as the reference plane, and the distance between the first latching portion 120 and the above reference plane is denoted as the height of the first latching portion 120, then, as Figure 9 shown, the first first latching portion 120 on the left and the first first latching portion 120 on the right are at the same height (counting from the bottom up), and the second first latching portion 120 on the left and the second second latching portion 118 on the right are at the same height (counting from the bottom up). By analogy, the nth first latching portion 120 on the left and the nth second latching portion 118 on the right are at the same height (counting from the bottom up), which is the "first latching portions 120 of the first component 121 are aligned with the first latching portions 120 of the second component 122 one by one". Among them, the reference plane is not shown in the drawings, and the reference plane can be a horizontal plane (in Figure 2 's perspective), and the reference plane can also be understood as the plane where the top edges of all side plates 111 are located.

[0039] Figure 10Shows the second latching portion 118 of the first component 121 and the second latching portion 118 of the second component 122. In Figure 10 , the left second connecting body 110 belongs to the first component 121, and the second latching portion 118 on the second connecting body 110 belongs to the first component 121. The right second connecting body 110 belongs to the second component 122, and the second latching portion 118 on the second connecting body 110 belongs to the second component 122. If the distance between the second latching portion 118 and the above-mentioned reference plane is denoted as the height of the second latching portion 118, then the second latching portion 118 of the first component 121 and the second latching portion 118 of the second component 122 are at different heights, which is the "second latching portion 118 of the first component 121 and the second latching portion 118 of the second component 122 are staggered from each other". More intuitively, in Figure 10 , the bottom end of the second latching portion 118 (the left second latching portion 118) of the first component 121 is flush with the straight line L 2 , and its top end is flush with the straight line L 1 . While the bottom end of the second latching portion 118 (the right second latching portion 118) of the second component 122 is located below the straight line L 2 , and the top end of the second latching portion 118 of the second component 122 is located below the straight line L 1 , in this way, the second latching portion 118 of the first component 121 and the second latching portion 118 of the second component 122 are staggered from each other.

[0040] The following explains why the above conditions are beneficial to reducing the risk that all latching components are not latched.

[0041] The design of the latching components in the prior art is roughly as follows: for any two first connecting bodies 109, the first latching portion 120 of one first connecting body 109 is aligned with the first latching portion 120 of the other first connecting body 109; and, for any two second connecting bodies 110, the second latching portions 118 of both are also aligned with each other. That is, all the latching components of the prior art buried box 100 are the same, and the design of staggering the latching portions is not adopted. When one latching component is not in the latched state, the other latching components will necessarily not be in the latched state. In an ideal state, after the face cover 102 and the box body 101 of the prior art buried box 100 are assembled, any latching component is in the latched state, that is, the mating relationship between the first latching portion 120 and the second latching portion 118 is as Figure 8As shown, the second clamping portion 118 is clamped in the clamping groove 124. However, during the actual installation of the embedded box 100, the installer may need to cut off a part of the box body 101 according to the conditions of the construction site and then install the face cover 102. Due to possible errors during cutting, after the face cover 102 and the box body 101 are assembled, the following situations may occur: None of the clamping components are in a clamped state, and the mating relationship between the first clamping portion 120 and the second clamping portion 118 is as Figure 7 As shown, the second clamping portion 118 is not clamped in the clamping groove 124, and the end faces of the first clamping portion 120 and the second clamping portion 118 are in contact with each other. Since none of the clamping components are in a clamped state, the connection between the face cover 102 and the box body 101 is not firm enough, and the face cover 102 is prone to looseness.

[0042] For the embedded box 100 of the present utility model, since the second clamping portions 118 of the first component 121 and the second component 122 are staggered from each other, the states of the first component 121 and the second component 122 are not completely the same. Even if the first component 121 is not in a clamped state (the second clamping portion 118 is not clamped in the clamping groove 124), the second component 122 can be in a clamped state (the second clamping portion 118 is clamped in the clamping groove 124), and the risk that both the second component 122 and the first component 121 are not in a clamped state is relatively low. Therefore, the embedded box 100 of the present utility model can reduce the risk that all the clamping components are not in a clamped state, thereby reducing the risk of the face cover 102 loosening.

[0043] Moreover, since the clamping component is provided with a plurality of first clamping portions 120 distributed along the orientation of the opening 107, the second clamping portion 118 can be clamped in different clamping grooves 124 according to actual needs. Even if the sizes of the cut-off parts of the box body 101 may be different in different usage scenarios, the clamping component can still achieve clamping, and the applicability of the embedded box 100 is relatively wide. In addition, the face cover 102 and the box body 101 of the embedded box 100 of the present utility model are clamped by the clamping component, and the face cover 102 and the box body 101 do not need to be fixed by a sealing ring, and the embedded box 100 overcomes the problem of the face cover 102 loosening caused by the aging of the sealing ring or the dimensional error of the sealing ring.

[0044] It should be noted that in some other embodiments, the first component 121 and the second component 122 can be changed to meet the following conditions: The first clamping portions 120 of the first component 121 and the second component 122 are staggered from each other, and moreover, the second clamping portions 118 of the first component 121 and the second component 122 are aligned. This condition can also reduce the risk that all the clamping components are not in a clamped state, and its principle is similar to the principle introduced above, and will not be elaborated here.

[0045] In some embodiments, the first component 121 and the second component 122 satisfy the following: after the face cover 102 and the box body 101 are assembled, one of the first component 121 and the second component 122 is in a clamped state, and the other is in a disengaged state. Among them, for the clamped component in the clamped state, the second clamping portion 118 is clamped in one of the clamping grooves 124 (as Figure 8 shown); for the clamped component in the disengaged state, the second clamping portion 118 is disposed outside the clamping groove 124 (as Figure 7 shown). The size of the cut-off part of the box body 101 may vary due to different usage scenarios, but at least a part of the clamped components in the embedded box 100 are in the clamped state, so as to ensure the connection firmness between the face cover 102 and the box body 101.

[0046] To reduce the space occupied by the embedded box 100, all the clamped components can be arranged inside the box body 101 (i.e., arranged in the inner cavity 106). In some embodiments, the number of the first components 121 and the number of the second components 122 can be equal. In this way, no matter in which usage scenario, half of the clamped components in the embedded box 100 are in the clamped state. Even in different usage scenarios, the connection firmness between the face cover 102 and the box body 101 is basically the same.

[0047] To improve the uniformity of the connection strength between the face cover 102 and the box body 101 in each region, the first component 121 and the second component 122 can be alternately distributed. For example, the clamped components are arranged in multiple rows and multiple columns (i.e., multiple clamped components are arranged in a rectangular array); in the same row, the first component 121 and the second component 122 are alternately arranged, and in the same column, the first component 121 and the second component 122 are also alternately arranged. "Alternately arranged" means that the first component 121 and the second component 122 are adjacent to each other, and there is no situation where two first components 121 are adjacent or two second components 122 are adjacent. For example, there are a total of 6 clamped components, and the clamped components are arranged in 3 rows and 2 columns; as Figure 3 shown, the second connecting bodies 110 in the three regions of D 1 、D 2 、D 3 belong to the second component 122, and the remaining three second connecting bodies 110 belong to the first component 121; as Figure 5 shown, the first connecting bodies 109 in the three regions of E 1 、E 2 、E 3 belong to the second component 122, and the remaining three first connecting bodies 109 belong to the first component 121.

[0048] In some embodiments, a plurality of cutting grooves 108 are further provided on the outer surface of the box body 101 (as Figure 8As shown in the figure, the cutting groove 108 is arranged around the opening 107 (as Figure 2 shown), and a plurality of cutting grooves 108 are distributed along the orientation of the opening 107. The cutting groove 108 may accommodate a part of the cutting tool (such as the tip, the cutting edge, etc. of the cutting tool). When the user uses the cutting tool to cut the box body 101, the user can insert the cutting tool into the cutting groove 108 and slide the cutting tool along the cutting groove 108, so as to cut the box body 101. The cutting groove 108 has a certain guiding effect on the cutting tool, which is convenient for the user to cut the box body 101 and reduces the dimensional error when cutting the box body 101.

[0049] Next, the shapes and structures of the first connecting body 109 and the second connecting body 110 will be introduced.

[0050] As Figure 9 shown, the first connecting body 109 further includes a first main body portion 119. One end of the first main body portion 119 is connected to the face cover 102. The first clamping portion 120 is connected to the outer surface of the first main body portion 119 (for example, connected to the outer peripheral surface of the first main body portion 119), and the first clamping portion 120 protrudes relative to the outer surface of the first main body portion 119. The outer surface of the first clamping portion 120 includes an abutting surface 125, and the abutting surface 125 is located at one end of the first clamping portion 120 away from the first main body portion 119. When the clamping assembly is in the disengaged state, the abutting surface 125 abuts against the second clamping portion 118 (reference can be made to Figure 7 and Figure 9 ). More specifically, the abutting surface 125 abuts against the end face of the second clamping portion 118. In the disengaged state, although the second clamping portion 118 is located outside the clamping groove 124, the second clamping portion 118 still contacts the first clamping portion 120, and the frictional force between the two can also serve as a resistance to the movement of the first clamping portion 120, thereby reducing the risk of loosening of the face cover 102. The outer surface of the first clamping portion 120 further includes a connecting surface 126. The two ends of the connecting surface 126 are respectively connected to the abutting surface 125 and the outer surface of the first main body portion 119, and the connecting surface 126 serves as a part of the wall surface of the clamping groove 124. When the clamping assembly is in the clamped state, the connecting surface 126 abuts against the second clamping portion 118, thereby hindering the face cover 102 from moving along the orientation of the opening 107.

[0051] If one end of the first engaging portion 120 away from the first main body portion 119 is referred to as the protruding end, and one end of the first engaging portion 120 close to the first main body portion 119 is referred to as the connecting end, then, from the connecting end to the protruding end, the width of the card slot 124 gradually increases. Such a setting is beneficial to preventing excessive resistance when the second engaging portion 118 moves, thereby facilitating the installation and / or disassembly of the face cover 102. Herein, the width of the card slot 124 refers to the dimension in the orientation of the opening 107, and the width of the card slot 124 may be the dimension of the card slot 124 in the up-down direction. In the case where the first engaging portion 120 is annular and the first main body portion 119 is cylindrical, the connecting end and the protruding end may be distributed along the radial direction of the first main body portion 119. To meet the above conditions, the connecting surface 126 may be inclined.

[0052] In some embodiments, the first main body portion 119 is cylindrical, the axial direction of the first main body portion 119 is parallel to the orientation of the opening 107, the first engaging portion 120 is annular and surrounds the first main body portion 119, the first engaging portion 120 is connected to the outer peripheral surface of the first main body portion 119 (the outer peripheral surface of the first main body portion 119 is a part of the outer surface of the first main body portion 119), and the first engaging portion 120 protrudes relative to the outer peripheral surface of the first main body portion 119. Correspondingly, the card slot 124 is an annular groove. It should be noted that the first connecting body 109 is not a screw, and the first engaging portion 120 is not a thread. The plurality of first engaging portions 120 can be regarded as a group of mutually parallel rings.

[0053] As Figure 4 shown, the second connecting body 110 includes a second main body portion 113 and an enclosing portion 114. One end of the second main body portion 113 is connected to the box body 101, and the other end of the second main body portion 113 is connected to the enclosing portion 114. A plurality of enclosing portions 114 are provided, and the plurality of enclosing portions 114 are spaced apart along the circumferential direction of the first main body portion 119, and adjacent enclosing portions 114 are separated by a notch 116. The plurality of enclosing portions 114 jointly enclose an insertion space 117, and the first connecting body 109 can be inserted into the insertion space 117 (as Figure 7 and Figure 8 shown). Each enclosing portion 114 is connected to a second engaging portion 118, the second engaging portion 118 is arc-shaped, and the second engaging portion 118 protrudes relative to the surface of the enclosing portion 114 facing the insertion space 117. That is, the second engaging portion 118 is connected to the inner circumferential surface of the enclosing portion 114 and protrudes relative to the inner circumferential surface of the enclosing portion 114. Reinforcing ribs 115 may be provided on the outer peripheral surfaces of the second main body portion 113 and the enclosing portion 114. It should be noted that in the same second connecting body 110, all the second engaging portions 118 are at the same height (for the definition of the height of the position where the second engaging portion 118 is located, please refer to the above, and the height needs to refer to the reference plane).

[0054] Since adjacent enclosures 114 are arranged at intervals from each other, multiple enclosures 114 can be folded together or opened together. When the user inserts the first connector 109 into the insertion space 117, the abutting surface 125 of the first clamping portion 120 can contact the end surface of the second clamping portion 118, so that the first connector 109 pushes the enclosure 114 open, and then multiple enclosures 114 are opened, which facilitates the insertion of the first connector 109. After the abutting surface 125 of the first clamping portion 120 is staggered from the end surface of the second clamping portion 118, the enclosure 114 can be folded together under its own elasticity, so that the second clamping portion 118 enters the card slot 124. Among them, the enclosure 114 can be made of plastic, and the enclosure 114 has elasticity. In addition, since the plurality of second clamping portions 118 are clamped together in an annular clamping groove 124 , the connection between the first connecting body 109 and the second connecting body 110 is more secure, and the risk of the cover 102 loosening is lower.
