Description

Technical Field

[0001] This invention relates to the field of recessed mounting box installation, and more specifically to a mounting plate for a recessed mounting box. Background Technology

[0002] In existing technologies, concealed boxes are typically installed on solid walls, false walls, and display panels. For solid walls and display panels, grooves are usually cut into them, and the concealed box is then attached to the bottom of the groove. When installed on a solid wall, grout is filled into the groove to cover most of the water pipes and the concealed box, leaving only the box panel exposed. This ensures aesthetics and avoids excessive grouting that wastes bathroom space. However, during construction, if the bottom of the groove is not vertical, the concealed box will also be uneven, causing the water pipes connected to it to be tilted. This can lead to problems such as the water outlet components (e.g., the overhead shower) being misaligned or unable to be installed. For solid walls, this can also cause the grout to fall off under pressure during sealing. While no grouting is needed on display panels, the tilted water pipes and misaligned water outlet components can negatively impact the display effect.

[0003] For installations on solid walls, while universal joints can solve assembly issues using existing technology, they cannot guarantee installation when the tilt is too large. For installations on solid walls and display panels, a level can be installed on the concealed box, or the box can be calibrated multiple times during installation to ensure the correct installation posture. However, this assembly method is cumbersome and inefficient. Furthermore, for display panels, different grooves need to be cut for different concealed boxes, leading to high grooving costs. While false walls also have grooves on their back surface, the larger grooves and easier verticality assurance prevent this problem during installation. Large grooves on solid walls and display panels significantly increase costs. Summary of the Invention

[0024] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0025] 1. In Scheme 1 and its preferred embodiments, to solve the assembly problem in the installation of solid walls and display panels, and the problem that display panels need to be cut with different grooves for different concealed boxes, resulting in high grooving costs, this scheme proposes an installation plate for concealed boxes. The concealed boxes are installed on the installation plate; the installation plate is fixed to the solid wall or display panel, thereby fixing the concealed boxes relative to the installation plate and the solid wall or display panel; when the installation plate is fixed to the solid wall, compared to the bottom surface of the solid wall, the verticality of the outer surface of the solid wall is determined by plumb bob during processing, thus ensuring verticality. During installation, the outer surface of the solid wall is used as a reference, and the first mounting surface of the installation plate is attached to the outer surface of the solid wall for installation. After installation, the verticality of the installation plate is guaranteed, thereby ensuring the verticality of the concealed boxes and ensuring assembly; since the bottom surface of the first mounting groove is behind the first mounting surface, the first mounting groove and the concealed box are mostly hidden in the groove of the solid wall, preventing excessive occupation of shower space; there is no need to significantly change the size of the groove of the solid wall, as long as the groove of the solid wall can accommodate the first mounting groove.

[0026] Similarly, when the mounting plate is fixed to the display panel, the outer surface of the display panel can be used as a reference during installation. The second mounting surface of the mounting plate is then attached to the outer surface of the display panel before installation. After installation, the verticality of the mounting plate is guaranteed, thereby ensuring the verticality of the concealed box and ensuring assembly. Since the second mounting surface is behind the bottom surface of the first mounting groove, the first mounting groove and the concealed box are located in front of the display panel. The display panel does not need to be slotted to hide the first mounting groove and the concealed box, reducing the cost of slotting the display panel. Furthermore, with the bottom surface of the first mounting groove facing forward, the front of the concealed box is always in front after installation, making it convenient for users.

[0027] 2. In Scheme 2 and its preferred embodiments, the verticality of the outer surface of the false wall is guaranteed. The third mounting surface faces forward and is suitable for fitting against the outer surface of the false wall. After installation, the verticality of the mounting plate is guaranteed, thereby ensuring the verticality of the concealed box. The first mounting surface, the bottom surface of the first mounting groove, and the second mounting surface are all behind the third mounting surface and will not affect the installation.

[0028] 3. In Scheme 3 and its preferred embodiments, the second mounting groove is located above the first mounting groove in the vertical direction. The concealed box is usually equipped with a top spray pipe, which is placed in the second mounting groove. Since the bottom surface of the second mounting groove is behind the first mounting surface, when the mounting plate is installed on a solid wall, the second mounting groove can also be mostly located in the groove of the solid wall to prevent occupying too much shower space. The bottom surface of the second mounting groove faces forward, that is, the opening of the second mounting groove faces forward, so that the top spray pipe can be installed in the second mounting groove from the front.

[0029] 4. In Scheme 4 and its preferred embodiments, it includes a first plate, a second plate, and a third plate, with the second plate forming an angle with the first and third plates; the two opposing surfaces of the second plate are respectively connected to the first and third plates, and the second and third plates enclose each other to form a first mounting groove, so the left and right ends and the bottom of the first mounting groove are hollowed out, and the left and right water pipes and the bottom water pipe on the concealed box can extend out from the hollowed-out parts; the first mounting surface and the third mounting surface are provided on the first plate, and the second mounting surface is provided on the third plate; the first plate is provided with a second mounting groove. This structure is more material-saving and can realize installation on false walls, solid walls, and display panels.

[0030] 5. In Scheme 5 and its preferred embodiments, the mounting plate includes two first plates, two second plates, and a third plate. The two first plates are spaced apart in the vertical direction, and the two second plates are also arranged in the vertical direction, forming an angle with the first and third plates. The two ends of the third plate in the vertical direction are connected to the two second plates respectively. The end of each first plate closest to the other first plate is connected to the end of the second plate away from the third plate. The two second plates and the third plate together form a first mounting groove. Therefore, the left and right ends of the first mounting groove are hollowed out, allowing the left and right water pipes on the concealed box to extend out through the hollowed-out areas. The upper first plate has a second mounting groove, allowing the installation of the top spray pipe. The first mounting surface and the third mounting surface are located on the first plate, and the second mounting surface is located on the third plate. This structure is simple and convenient, and can be installed on false walls, solid walls, and display panels. The number of first plates is two, increasing strength.

[0031] 6. In Scheme 6 and its preferred embodiments, the first plate is provided with a first clearance hole extending in the vertical direction and opening on the front surface of the first plate, and the second plate is provided with a second clearance hole communicating with the first clearance hole and penetrating the second plate in the vertical direction. This allows the top spray pipe and the bottom water pipe to be inserted into the first clearance hole and the second clearance hole from the front when installed in the first mounting groove with the concealed box, and to extend upward or downward from the second clearance hole, so as to facilitate wall-mounted installation and reduce the overall space occupied.

[0032] 7. In Scheme 7 and its preferred embodiments, the first plate with the second mounting groove is also provided with a second mounting surface. When the mounting plate is installed on the display plate, the upper end is suspended. When the top spray pipe is locked, the force on this end will cause the first plate to bend, affecting the use and installation of the top spray pipe. Therefore, the second mounting surface is also provided on the first plate to play a supporting role.

[0033] 8. In Scheme 8 and its preferred embodiments, the first plate with the second mounting groove includes two first parts, two second parts, and a third part. The two first parts are arranged at intervals along the left and right directions perpendicular to the up-down and front-back directions. The two second parts are arranged along the left and right directions, and the second parts form an angle with the first and third parts. The two ends of the third part along the left and right directions are respectively connected to the two second parts. The end of each first part near the other first part is respectively connected to the end of the second part away from the third part. The two second parts and the third part enclose each other to form the second mounting groove. The second mounting groove is hollowed out at the top and bottom, so as to accommodate the top water spray pipe. The first mounting surface and the third mounting surface are provided on the first part, and the second mounting surface is provided on the third part, so as to realize installation in multiple scenarios and provide support when locking the top water spray pipe.

[0034] 9. In Scheme Nine and its preferred embodiments, since the first plate body only needs to have a second mounting surface when the mounting plate is installed on the display plate, it is not needed when the mounting plate is installed on the false wall and the solid wall. However, setting a second mounting surface on the first plate body would result in a longer length of the second part connected to the third part in the front-back direction, increasing the cost. Therefore, by making the support member detachable from the plate part, the mounting plate is only used when there is a display plate. For the false wall and the solid wall, the mounting plate that can be removed from the support member can be used to reduce the cost. Furthermore, when the mounting plate is installed on the solid wall, the groove depth of the second mounting groove is shallower, which can accommodate the top spray pipe. When the groove is cut on the solid wall corresponding to the first plate body, the groove depth can be even smaller, reducing the processing cost.

[0035] 10. In Scheme 10 and its preferred embodiments, both first parts are connected to the second plate, and the second and third parts are spaced apart from the second plate, reducing the connection with the second plate and saving costs.

[0036] 11. In Scheme 11 and its preferred embodiments, the first part includes a first segment, a second segment and a third segment. The first segment and the third segment are arranged from back to front. The second segment connects the first segment and the third segment. The third segment connects the second part. The first segment is provided with a first mounting surface. The third segment is provided with a third mounting surface. By setting a bending segment in the first part, the strength is increased and the bending resistance is improved.

[0037] 12. In Scheme Twelve and its preferred embodiments, the first plate, the second plate, and the third plate all have bending sections. By setting the bending sections, the strength is increased and the bending resistance is improved.

[0038] 13. In Scheme Thirteen and its preferred embodiments, the mounting plate is further provided with a plurality of first screw through holes, second screw through holes and third screw through holes that penetrate the mounting plate in the front-back direction. One end of the first screw through hole opens into the first mounting surface, one end of the second screw through hole opens into the second mounting surface, and one end of the third screw through hole opens into the third mounting surface. Each of them has a screw through hole to prevent the assembly from being affected when the projections of the first mounting surface, the second mounting surface and the third mounting surface do not overlap.

[0039] 14. In Scheme Fourteen and its preferred embodiments, the mounting plate is further provided with a plurality of second screw through holes and fourth screw through holes that penetrate the mounting plate in the front-back direction. One end of the second screw through hole opens into the second mounting surface; the two ends of the fourth screw through hole are respectively opened into the first mounting surface and the third mounting surface. In this embodiment, the projections of the first mounting surface and the third mounting surface overlap, and the fourth screw through hole can be opened into the first mounting surface and the third mounting surface at both ends, making the structure simpler.

[0040] 15. In Scheme 15 and its preferred embodiments, the first screw through hole, the second screw through hole and the third screw through hole are all strip holes, and the installation position can be adjusted to reduce assembly accuracy.

[0041] 16. In Scheme Sixteen and its preferred embodiments, the bottom wall of the second mounting groove is provided with a fixing hole for locking the top spray pipe.

[0042] 17. In Scheme 17 and its preferred embodiments, the mounting plate is made of at least two plates spliced ​​together, which facilitates the transportation and packaging of the mounting plate. Attached Figure Description

[0072] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0073] Example 1

[0074] refer to Figures 1-2 A mounting plate 10 for a concealed box is suitable for attaching to the outer surface of a solid wall 20, a display panel 30, and a false wall 40 and for fixing the solid wall 20, the display panel 30, and the false wall 40.

[0075] The mounting plate 10 includes two first plates 1, two second plates 2, and a third plate 3. The two first plates 1 are spaced apart along the vertical direction 91, and the two second plates 2 are also spaced apart along the vertical direction 91. The second plates 2 form an angle with the first plates 1 and the third plates 3. In this embodiment, the second plates 2 are perpendicular to the first plates 1 and the third plates 3. The vertical direction is perpendicular to the ground.

[0076] The two second plates 2 and the two first plates 1 are all located in front of the third plate 3. The front-back direction 93 is perpendicular to the up-down direction 91. Taking the mounting plate 10 installed on a solid wall as an example, the direction facing the solid wall is the rear, and the direction away from the solid wall is the front.

[0077] The third plate 3 is connected to the two second plates 2 at both ends along the vertical direction 91, so that the two second plates 2 and the third plate 3 enclose each other to form a first mounting groove 4. The bottom surface of the first mounting groove 4 faces forward. The concealed box is installed on the mounting plate 10 and is suitable for being placed in the first mounting groove 4. Since the first mounting groove 4 is formed by only three plates, its left and right ends are hollowed out to allow water pipes, such as hot and cold water pipes, to pass through. The left and right direction 92 is perpendicular to the front and back direction 93 and the vertical direction 91. In this embodiment, the third plate 3 has several studs 31 protruding forward. The concealed box is provided with a first through hole. The studs 31 pass through the first through hole and are screwed with nuts to realize the installation of the concealed box. Of course, in addition to the above method, the third plate 3 can also be provided with threaded holes, or the second plate 2 can be provided with snap-fit ​​parts, etc. The detachable connection method helps to disassemble and replace the concealed box. For example, when used on the display plate 30, different concealed boxes can be displayed by disassembling and replacing them from the mounting plate 10. Of course, it can also be fixed in a non-removable way, such as by attaching a concealed box to the third plate 3. The second plate 2 is provided with a second clearance hole 21, which penetrates the second plate 2 along the vertical direction 91.

[0078] refer to Figure 2 The third plate 3 is also provided with a second mounting surface 32 perpendicular to the front-back direction 93. The second mounting surface 32 is the rear surface of the third plate 3, facing the rear, and is suitable for adhering to the outer surface of the display plate 30.

[0079] Each first plate 1 has its end near the other first plate 1 connected to the end of the second plate 2 away from the third plate 3. That is, the lower end of the upper first plate 1 is connected to the upper second plate 2, and the upper end of the lower first plate 1 is connected to the lower second plate 2.

[0080] refer to Figure 2 The first plate 1 has a first mounting surface 11 and a third mounting surface 12 perpendicular to the front-rear direction 93. The first mounting surface 11 is the rear surface of the first plate 1, facing rearward, and is suitable for fitting against the outer surface of the solid wall 20. The third mounting surface 12 is the front surface of the first plate 1, facing forward, and is suitable for fitting against the outer surface of the false wall 40. Furthermore, the third mounting surface 12, the first mounting surface 11, the bottom surface of the first mounting groove 4, and the second mounting surface 32 are arranged sequentially from front to back. The first plate 1 has a first clearance hole 13 extending along the vertical direction 91 and opening on the front surface of the first plate 1. The first clearance hole 13 communicates with the second clearance hole 21. When the first clearance hole 13 is in the form of a through hole, it saves more material. The first clearance hole 13 can also be in the form of a countersunk hole. In this form, since the water pipe needs to extend from the deeper first mounting groove 4, the water pipe may need to be bent to a certain extent. This allows the top spray pipe and the bottom water pipe to be inserted into the first clearance hole 13 and the second clearance hole 21 from the front when the concealed box is installed in the first mounting groove 4, and to extend upward or downward from the second clearance hole 21. The top spray pipe can extend upward, and the faucet water pipe can extend downward, so as to facilitate wall-mounted installation and reduce the overall space occupied.

[0081] The first plate 1 located above is also provided with a second mounting groove 14. The bottom surface of the second mounting groove 14 faces forward, that is, the opening of the second mounting groove 14 faces forward, so that the top spray pipe can be installed in the second mounting groove 14 from the front. The bottom surface of the second mounting groove 14 is located behind the first mounting surface 11. Therefore, when the mounting plate 10 is installed on the solid wall 20, the second mounting groove 14 can also be mostly located in the groove of the solid wall 20, preventing excessive occupation of shower space. The second mounting groove 14 is located above the first mounting groove 4 in the vertical direction. The bottom surface of the second mounting groove 14 is located in front of the second mounting surface 32. In this way, when the mounting plate 10 is installed on the display plate 30, the bottom wall of the second mounting groove 14 is located in front of the display plate 30, and there is no need to cut grooves on the display plate 30 to hide the second mounting groove 14, reducing the cost of cutting grooves on the display plate 30. As mentioned above, when the first clearance hole 13 is also in the form of a countersunk hole, the bottom of the first clearance hole 13 can be flush with the bottom surface of the second mounting groove 14.

[0082] refer to Figure 1The first plate 1 with the second mounting groove 14 includes two first parts 15, two second parts 16, and a third part 17. The two first parts 15 are arranged at intervals along the left-right direction 92 so that a first clearance hole 13 is formed between the two first parts 15. The two second parts 16 are arranged along the left-right direction 92. The first parts 15 and the second parts 16 are both located in front of the third part 17. The second part 16 forms an angle with the first part 15 and the third part 17. In this embodiment, the second part 16 is perpendicular to the first part 15 and the third part 17.

[0083] The third part 17 is connected to the two second parts 16 at both ends along the left-right direction 92. The end of each first part 15 near the other first part 15 is connected to the end of the second part 16 away from the third part 17. The two second parts 16 and the third part 17 enclose each other to form a second mounting groove 14. Since the second mounting groove 14 is formed by the two second parts 16 and the third part 17, the second mounting groove 14 is hollowed out vertically, which is suitable for the installation of the top spray water pipe extending upward from the concealed box. The first mounting surface 11 and the third mounting surface 12 are provided on the first part 15, and the front and rear surfaces of the first part 15 respectively form the third mounting surface 12 and the first mounting surface 11.

[0084] Both first parts 15 are connected to the second plate 2, and the second part 16 and the third part 17 are spaced apart from the second plate 2, thereby reducing the connection between the first plate 1 and the second plate 2, reducing materials, and saving costs.

[0085] The third part 17 (i.e., the bottom wall of the second mounting groove 14) is also provided with a fixing hole 171 that runs through the third part 17 in the front-back direction 93. There are two fixing holes 171, which are strip-shaped holes that extend in the left-right direction 92 and in the up-down direction 91, respectively, so as to facilitate the fixing of top spray water pipes of different sizes. The top spray is relatively heavy and the top spray water pipe extends upward, which is easy to bend. After fixing through the fixing hole 171, it can be ensured that the top spray water pipe is vertical. The specific fixing method can be to fix it by using a half ring sleeve. The half ring sleeve is fitted on the front end of the top spray water pipe, the screw passes through the half ring sleeve and then through the fixing hole 171, and then is locked by a nut.

[0086] The first plate 1 located below also has two first parts 15 and a first clearance hole 13, but does not have a second part 16 and a third part 17.

[0087] Mounting plate 10 is also provided with a plurality of second screw through holes 5 and fourth screw through holes 6 that pass through the mounting plate 10 in the front-rear direction 93. The second screw through holes 5 pass through the plate having the second mounting surface 32 and one end of the second screw through hole 5 opens into the second mounting surface 32. The two ends of the fourth screw through holes 6 are respectively opened into the first mounting surface 11 and the third mounting surface 12 (the projections of the first mounting surface 11 and the third mounting surface 12 coincide, such as the front and rear surfaces of a plate forming the first mounting surface 11 and the third mounting surface 12 respectively, or having two parallel plates, the rear plate having the first mounting surface 11 and the front plate having the second mounting surface 32, and the second screw through holes 5 passing through both plates at the same time). After passing through the second screw through hole 5 and the fourth screw through hole 6, the screws are locked to the nuts on the solid wall 20, the false wall 40, and the display plate 30. The second screw through hole 5 and the fourth screw through hole 6 are strip-shaped holes extending in the vertical direction 91, which facilitates the adjustment of the installation height of the mounting plate 10, reduces the precision of the nut position, and makes assembly easier. This method facilitates disassembly and adjustment. It should be understood that if the left and right position of the mounting plate 10 is to be easily adjusted, each screw through hole can also be a strip-shaped hole extending in the left and right direction 92. In addition, if it is necessary to adjust the left and right position and height of the mounting plate 10, it can be a strip-shaped hole extending at an angle relative to the left and right direction 92 and the vertical direction 91.

[0088] The structure is simple and convenient, enabling the mounting plate 10 to be installed on the false wall 40, solid wall 20, and display panel 30, and the assembly is simple.

[0089] Example 2

[0090] In this embodiment, the mounting plate 10 is integrally formed. When the mounting plate 10 is installed on the display plate 30, since the second mounting surface 32 is only present at the third plate body 3 and not at the second mounting groove 14, when the top spray pipe is locked onto the mounting plate 10 through the fixing hole 171, the force on that end will cause the first plate body 1 to bend, affecting its use and the installation of the top spray pipe. Therefore, in this embodiment, based on the first embodiment, referring to... Figure 3 The first plate 1 with the second mounting groove 14 is also provided with a second mounting surface 32. The rear surface of the first plate 1 with the second mounting groove 14 forms the second mounting surface 32; that is, the second mounting surface 32 is provided in the third part 17, and the rear surface of the third part 17 forms the second mounting surface 32, thereby playing a supporting role.

[0091] Example 3

[0092] Since the first plate body 1 only needs to have a second mounting surface 32 when the mounting plate 10 is installed on the display plate 30 (as required by the manufacturer), it is not needed when the mounting plate 10 is installed on the false wall 40 and the solid wall 20 (as required by the user). However, setting a second mounting surface 32 for the first plate body 1 would result in a longer length of the second part 16 connected to the third part 17 in the front-rear direction 93, which would increase the cost.

[0093] Therefore, this embodiment is based on Embodiment 2, with reference to... Figures 4-6 The third part 17 is disassembled, and includes a plate 172 and a support member 173. The plate 172 is connected to the second part 16 and is integrally formed. A fixing hole 171 is provided in the plate 172, and the support member 173 is provided with a second screw through hole 5. The support member 173 and the plate 172 are detachably fixed. In this embodiment, they are connected by screws. The through hole on the plate 172 for connecting with the support member 173 can be processed later. The support member 173 forms a second mounting surface 32 on the surface opposite to the plate portion 172. The second screw through hole 5 opens into the second mounting surface 32. Therefore, the support member 173 is detachable from the plate portion 172. The mounting plate 10 of this embodiment is only used when there is a display plate 30. The false wall 40 and the solid wall 20 can use the mounting plate 10 of this embodiment, which reduces costs. When the mounting plate 10 is installed on the solid wall 20, the second mounting groove 14 is shallower in this embodiment, which can accommodate the top spray pipe. When the groove is cut on the solid wall 20 corresponding to the first plate 1, the groove depth can be smaller, reducing processing costs. The top spray pipe can have a bent pipe to turn from the deeper first mounting groove 4 to the shallower second mounting groove 14.

[0094] Example 4

[0095] Based on the above embodiments one to three, when the mounting plate 10 is used, since some top sprayers are quite heavy, the weight of the top sprayers will be transferred to the mounting plate 10 through the top spray water pipe. If the mounting plate 10 is not strong enough, it will cause problems such as deformation of the mounting plate 10, affecting subsequent use.

[0096] Therefore, this embodiment is based on the above embodiments one to three, and refers to... Figure 7 The first plate 1, the second plate 2, and the third plate 3 are provided with backward bending sections, thereby increasing the strength of the mounting plate 10.

[0097] refer to Figure 7Specifically, in the first plate 1, the first part 15 of the first plate 1 has a bent section. The first part 15 includes a first segment 151, a second segment 152 and a third segment 153. The first segment 151 and the third segment 153 are arranged from back to front. The second segment 152 connects the first segment 151 and the third segment 153. The third segment 153 connects the second part 16. The first segment 151 is provided with a first mounting surface 11. The rear surface of the first segment 151 forms the first mounting surface 11. The third segment 153 is provided with a third mounting surface 12. The front surface of the third segment 153 forms the third mounting surface 12.

[0098] Similarly, the second plate 2 and the third plate 3 also have three bending segments to increase strength. Of course, more bending segments can be added, but we will not go into details here.

[0099] During installation, the concealed box is installed on the mounting plate 10; the mounting plate 10 is fixed to the solid wall 20, the display panel 30, or the false wall 40, thereby fixing the concealed box relative to the mounting plate 10 and the solid wall 20, the display panel 30, or the false wall 40.

[0100] When the mounting plate 10 is installed and fixed to the solid wall 20, a groove is cut into the solid wall 20. The first mounting surface 11 of the mounting plate 10 fits against the outer surface of the solid wall 20, and the remaining part is embedded in the groove of the solid wall 20. Then, the mounting plate 10 is fixed to the solid wall 20 with screws. After the concealed box and water pipe are assembled, they are installed in the first mounting groove 4 and then locked. The installation is carried out with the outer surface of the solid wall 20 as a reference. After the installation is completed, the verticality of the mounting plate 10 is guaranteed, thereby ensuring the verticality of the concealed box and ensuring assembly. Since the bottom surface of the first mounting groove 4 is behind the first mounting surface 11, the first mounting groove 4 and the concealed box are mostly hidden in the groove of the solid wall 20, preventing excessive occupation of shower space. There is no need to significantly change the size of the groove of the solid wall 20, as long as the groove of the solid wall 20 can accommodate the first mounting groove 4.

[0101] When the mounting plate 10 is installed and fixed to the display plate 30, the outer surface of the display plate 30 is used as a reference. First, the support member 173 is fixed to the display plate 30, and the second mounting surface 32 under the mounting plate 10 is attached to the outer surface of the display plate 30. Then, the plate part 172 and the support member 173 are locked together to complete the installation of the mounting plate 10. After the concealed box and water pipe are assembled, they are installed in the first mounting groove 4 and then locked. After the second mounting surface 32 of the mounting plate 10 is attached to the outer surface of the display plate 30, it is installed by screws passing through the second screw through hole 5. After installation, the verticality of the mounting plate 10 is guaranteed, thereby ensuring the verticality of the concealed box and ensuring assembly. Since the second mounting surface 32 is behind the bottom surface of the first mounting groove 4, the first mounting groove 4 and the concealed box are located in front of the display plate 30. There is no need to cut grooves on the display plate 30 to hide the first mounting groove 4 and the concealed box, reducing the cost of cutting grooves on the display plate 30. And the bottom surface of the first mounting groove 4 faces forward, which ensures that the front of the concealed box is in front after installation, which is convenient for users.

[0102] When the mounting plate 10 is installed and fixed to the false wall 40, the concealed box and water pipe are assembled and installed in the first mounting groove 4, and then locked. The concealed box hole is opened on the wall surface of the false wall 40, and then it is installed from back to front, so that the third mounting surface 12 is attached to the outer surface of the false wall 40 and locked. The third mounting surface 12 is suitable for being attached to the outer surface of the false wall 40 and then installed by screws through the third screw through hole. After the installation is completed, the verticality of the mounting plate 10 is guaranteed, thereby ensuring the verticality of the concealed box. The first mounting surface 11, the bottom surface of the first mounting groove 4, and the second mounting surface 32 are all behind the third mounting surface 12 and will not affect the installation.

[0103] Example 5

[0104] Based on Embodiment 4, to increase strength, in the case of integral bending molding, the first mounting surface 11 and the third mounting surface 12 are staggered, and the openings at both ends of the screw through hole cannot be respectively opened on the first mounting surface 11 and the third mounting surface 12. If the screw through hole is only provided in the first segment 151, and the screw through hole opens in the first mounting surface 11, then when the mounting plate 10 is installed on the false wall 40, since there is a distance between the first segment 151 and the outer surface of the false wall 40, it is suspended. Therefore, when the force is applied to the first segment 151 when the screw is tightened, it will cause the first segment 151 to bend. If the screw through hole is only provided in the third segment 153, when the mounting plate 10 is installed on the solid wall 20, the third segment 153 is also easy to bend under the force of the screw. After bending, it will affect subsequent use.

[0105] Therefore, in this embodiment, reference Figure 8The mounting plate 10 is also provided with a number of first screw through holes 7, second screw through holes 5 and third screw through holes 8 that pass through the mounting plate 10 in the front-back direction 93. One end of the first screw through hole 7 opens into the first mounting surface 11, one end of the second screw through hole 5 opens into the second mounting surface 32, and one end of the third screw through hole 8 opens into the third mounting surface 12. Specifically, the first screw through hole 7 passes through the first segment 151, the third screw through hole 8 passes through the third segment 153, and the second screw through hole 5 passes through the third plate body 3.

[0106] When the mounting plate 10 is installed on the false wall 40, it can be installed directly through the third screw through hole 8. Since the third section 153 will directly adhere to the outer surface of the false wall 40, the third section 153 will not deform during locking. Each of them has a screw through hole to prevent the first mounting surface 11, the second mounting surface 32, and the third mounting surface 12 from not overlapping and affecting the assembly.

[0107] The first screw through hole 7, the second screw through hole 5, and the third screw through hole 8 are strip-shaped holes extending in the vertical direction 91, which facilitates the adjustment of the installation height of the mounting plate 10, reduces the accuracy of the nut position, and makes assembly easier.

[0108] When the mounting plate 10 is installed and fixed to the solid wall 20, the first mounting surface 11 of the mounting plate 10 is attached to the outer surface of the solid wall 20 and then installed by screws passing through the first screw hole 7.

[0109] When the mounting plate 10 is installed and fixed to the display plate 30, the outer surface of the display plate 30 is used as a reference during installation. After the second mounting surface 32 of the mounting plate 10 is attached to the outer surface of the display plate 30, the installation is carried out by screws passing through the second screw through hole 5.

[0110] When the mounting plate 10 is installed and fixed to the false wall 40, the third mounting surface 12 is adapted to fit against the outer surface of the false wall 40 and then installed by screws passing through the third screw through hole 8.

[0111] Example 6

[0112] refer to Figure 18 , Figure 19 The difference between this embodiment and embodiments one to five is that the mounting plate 10 includes only a first plate 1, a second plate 2, and a third plate 3. The second plate 2 forms an angle with the first plate 1 and the third plate 3. The two opposing surfaces of the second plate 2 are respectively connected to the first plate 1 and the third plate 3. The second plate 2 and the third plate 3 enclose each other to form a first mounting groove 4. The first mounting surface 11 and the third mounting surface 12 are provided on the first plate 1, and the second mounting surface 32 is provided on the third plate 3. The first plate 1 is provided with a second mounting groove 14. This structure is more material-saving, but its strength will be slightly lower compared to having two first plates 1.

[0113] Example 7

[0114] In the above embodiments, the mounting plate 10 is mostly integrally bent and formed. In Embodiment 3, except for the support member 173, it is also integrally formed. Both of these will result in the mounting plate 10 being relatively long, which will make transportation and packaging more troublesome. In this embodiment, the mounting plate 10 can be formed by splicing at least two plates. Splicing is connecting multiple plates into one piece, including but not limited to the following methods: screw connection, plug connection, snap connection, hinge connection.

[0115] For example, taking the mounting plate 10 as an example where it is composed of two plates joined together, in this embodiment, refer to Figure 20 The joint line between the two plates is Figure 20 As shown, the lower plate includes a first mounting groove 4, a third mounting surface 12, a first mounting surface 11, and a second mounting surface 32, while the upper plate includes a second mounting groove 14, a third mounting surface 12, and a first mounting surface 11. It should be understood that, depending on the splitting of the mounting plate 10, in addition to the above possibilities, the joint position of the mounting plate 10 may be different. The lower plate may only have a first mounting groove 4 and a second mounting surface 32, which will not be elaborated further here.

[0116] Mounting plate 10 is assembled from two plates and a hinge. The hinge connects the two plates, allowing them to rotate relative to each other and fold, reducing space occupation. Alternatively, mounting plate 10 can be assembled by inserting two plates together. To ensure stability after insertion, the two plates can be secured with screws. Another option is to assemble mounting plate 10 by snapping two plates together. Or, mounting plate 10 can be assembled by screwing two plates together, with one plate having a nut and the other having a threaded portion. Mounting plate 10 can also be assembled by securing the two plates with screws. When assembling by rotation, the first mounting surface 11, the third mounting surface 12, and the second mounting surface 32 may not be parallel to each other. To solve this problem, an anti-rotation positioning surface can be provided on one plate. When the other plate rotates to abut against the anti-rotation positioning surface, the first mounting surface 11, the third mounting surface 12, and the second mounting surface 32 will be parallel to each other. Similarly, to prevent the two plates from rotating relative to each other after installation, they can also be secured with screws. The above connection structures are not specifically shown in the figure.

[0117] It should be understood that mounting plate 10 can be formed by splicing together a larger number of plates to achieve a simpler effect in terms of transportation and packaging. However, it is more difficult to ensure that the first mounting surface 11, the third mounting surface 12, and the second mounting surface 32 are parallel to each other. Therefore, in this embodiment, it is preferred to use 2 or 3 plates to splice together to form mounting plate 10, which can ensure that they are parallel to each other, facilitate transportation and installation, reduce processing trouble, and increase splicing efficiency.

Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
