[0059] A concealed box 10 suitable for mounting and fixing to a solid wall 20 or a wooden wall or a false wall, the concealed box 10 comprising a box body 1, a mounting plate 2 and a fastening screw 3;

[0060] Referring to Figure 1 The box body 1 comprises a first part 11 and a second part 12, the first part 11 is located in front of the second part 12, the first part 11 is usually used to install components such as panels, and the second part 12 is usually used to install valve cores and the like, which occupies a large space, so its size is generally designed to be larger than that of the first part 11. In this embodiment, the front refers to the direction in which the operating panel of the box body 1 faces, and the operating panel is arranged forward when the mounting box 10 is installed on a solid wall and a wooden wall 30, a false wall, and the surface of the operating panel is the front surface of the box body 1, or it can also be said that the side of the solid wall facing the user is the front. The diameter of the first part 11 is smaller than the diameter of the second part 12, and the side wall of the second part 12 is provided with a first fixing part 13, a pipe part 14 and a second fixing part 15 arranged in front to back order.

[0061] The first fixing part 13 and the second fixing part 15 are both provided with a receiving groove 131, and the receiving groove 131 is also provided with a limiting surface 1313 opposite to the groove bottom, and the groove bottom of the receiving groove 131 is at an angle with the front-back direction 40. In this embodiment, the receiving groove 131 has two openings communicating with each other, one opening of the receiving groove 131 of the first fixing part 13 is on the front surface of the second part 12, and the other opening is on the side wall of the second part 12, and one opening of the receiving groove 131 of the second fixing part 15 is on the rear surface of the second part 12, and the other opening is on the side wall of the second part 12. The receiving groove 131 comprises a first groove 1311 and a second groove 1312, and the side wall of the first groove 1311 forms a second stop surface 1314. The second groove 1312 is opened on the groove bottom of the first groove 1311, and the groove bottom of the second groove 1312 is the groove bottom of the receiving groove 131, and the second groove 1312 also extends in the circumferential direction to form the limiting surface 1313 opposite to the groove bottom of the receiving groove 131.

[0062] Both the first fixing part 13 and the second fixing part 15 are also provided with a limiting part 132. The limiting part 132 protrudes radially from the first groove 1311. The limiting part 132 is provided with a guide slope 1321 and a first anti-rotation surface 1322, with the first anti-rotation surface 1322 facing the second anti-rotation surface 1314. In this embodiment, since the mounting plate 2 needs to be flipped during installation, the guide slope 1321, the first anti-rotation surface 1322, and the second anti-rotation surface 1314 of the first fixing part 13 are oriented oppositely to the guide slope 1321, the first anti-rotation surface 1322, and the second anti-rotation surface 1314 of the second fixing part 15.

[0063] refer to Figure 2 , Figure 3 The mounting plate 2 has a ring-shaped structure and is fitted onto the box body 1. The mounting plate 2 includes a body 21, a flexible locking part 22, and an unlocking part 23.

[0064] refer to Figure 2 , Figure 3 The main body 21 includes a mounting hole and a mounting portion 211 protruding from the wall of the mounting hole. The mounting hole is adapted to be fitted onto the housing 1. The mounting portion 211 is strip-shaped and adapted to be detachably fixed to the first fixing portion 13 or the second fixing portion 15, so that the mounting plate 2 is detachably fixed to the first fixing portion 13 or the second fixing portion 15 and adapted to be placed into the receiving groove 131. In this embodiment, reference is made to... Figure 4 When the mounting part 211 is fixed to the first fixing part 13, the front surface of the box body 1, the mounting plate 2, and the pipe part 14 are arranged sequentially from front to back to accommodate the installation of the wooden wall 30 or the false wall. The mounting plate 2 is used to fit and fix to the wooden wall 30, and the pipe part 14 is located behind it. The pipe connected to the pipe part 14 is also located in the rear direction, thereby achieving concealment. The front surface of the box body 1 is in front of the mounting plate 2, so that it can pass through the hole on the wooden wall 30 and be exposed on the front surface of the wooden wall 30, which is convenient for users to use.

[0065] Pipe section 14 is used to connect to a water pipe to achieve functions such as water inlet or outlet, as in this embodiment, refer to Figure 9 The upward-facing water pipe can be used to connect to the overhead shower, the water pipes on both sides can be used to connect to hot and cold water, and the downward-facing water pipe can be used to connect to the faucet. Of course, in addition to the above methods, there can be other numbers of pipe sections 14, which will not be elaborated on here.

[0066] refer to Figure 5 When the mounting part 211 is fixed to the second fixing part 15, the mounting plate 2 has a surface that is flush with or located behind the rear surface of the box body 1 to adapt to solid wall installation. The surface of the mounting plate 2 that is flush with or located behind the rear surface of the box body 1 fits and is fixed to the bottom of the groove on the solid wall, which makes it easier to position and install. At the same time, the front surface of the box body 1 can also be exposed on the front surface of the solid wall 20, which is convenient for users.

[0067] In the present embodiment, the mounting plate 2 is connected to the first fixing part 13 or the second fixing part 15 by a rotating clamping manner. When the mounting plate 2 is mounted on the first fixing part 13 and the second fixing part 15, the posture of the mounting plate 2 is opposite. Specifically, the body 21 of the mounting plate 2 is provided with a first mounting surface 212 perpendicular to the front-rear direction 40. When the mounting part 211 is fixed to the first fixing part 13, the front surface of the box body 1, the first mounting surface 212 and the duct part 14 are arranged in sequence from front to back, and the first mounting surface 212 faces forward. Figure 4 Figure 5 When the mounting part 211 is fixed to the second fixing part 15, the first mounting surface 212 is flush with the rear surface of the box body 1 or located behind the rear surface of the box body 1, and the first mounting surface 212 faces backward. Taking the case that the mounting plate 2 is fixed to the second fixing part 15 as an example, the first mounting surface 212 is the rear surface of the mounting plate 2.

[0068] The mounting plate 2 is sleeved on the box body 1, and is inserted into the box body 1 along the front-rear direction 40 to make the mounting part 211 enter the containing groove 131, and then is rotationally matched with the box body 1 around the rotation axis parallel to the front-rear direction 40, so that the mounting part 211 respectively abuts against the limiting surface 1313 and the groove bottom of the containing groove 131 along the front-rear direction 40, thereby preventing the mounting plate 2 from being separated from the box body 1 along the front-rear direction 40.

[0069] As shown in Figure 2 or Figure 3 The body 21 is further provided with a plurality of screw through holes 213 penetrating the mounting plate 2 along the front-rear direction 40.

[0070] As shown in Figure 3 There is a gap between the unlocking part 23 and the body 21 along the radial direction of the mounting plate 2, which is used for deforming the unlocking part 23 in the direction of the body 21 when the unlocking part 23 is pressed. The unlocking part 23 extends along the front-rear direction, one end of the unlocking part 23 is fixedly connected with the body 21, and the other end is a free end. The flexible locking part 22 protrudes in the direction of the rotation axis, and is located between the two ends of the unlocking part 23, and in the present embodiment, is located in the middle part of the unlocking part 23. In this way, the flexible locking part 22 and the free end of the unlocking part 23 form an "L" shape, forming a space for the finger or the nail to press the unlocking part 23.

[0071] ​The guide slope 1321 and the first rotation-stopping surface 1322 are arranged in sequence along the rotating mounting direction of the mounting plate 2, and the rotating mounting direction is the direction of assembling and fixing the mounting plate 2 with the first fixing part or the second fixing part. The flexible locking part 22 is adapted to be acted on by the guide slope 1321 to pass the limiting part 132, and is adapted to abut against the first rotation-stopping surface 1322 and the second rotation-stopping surface 1314, thereby preventing the mounting plate 2 from being reversed and rotated after being mounted, and ensuring the stability during use, and preventing the mounting plate 2 from running. Specifically, when the flexible locking part 22 abuts against the guide slope 1321, the flexible locking part 22 will deform to drive the unlocking part 23 towards the gap between the unlocking part 23 and the body 21 under the action of force, until the flexible locking part 22 passes the limiting part 132, and the unlocking part 23 drives the flexible locking part 22 to reset under the action of the elastic force, so that the flexible locking part 22 is adapted to abut against the first rotation-stopping surface 1322 and the second rotation-stopping surface 1314, respectively. When the flexible locking part 22 is subjected to force in a direction away from the rotation axis, the flexible locking part 22 is driven to move in a direction away from the rotation axis, so that the flexible locking part 22 is separated from the abutment with the first rotation-stopping surface 1322 and the second rotation-stopping surface 1314, thereby realizing unlocking, and then the mounting plate 2 is disassembled through forward rotation or reverse rotation of the mounting plate 2.

[0072] As shown in Figure 4 , when mounted on the first fixing part 13, the mounting plate 2 is inserted from front to back, and the mounting plate 2 is rotated along the first circumferential direction, and after the mounting is completed, the free end of the unlocking part 23 faces forward, and the free end of the unlocking part 23 and the side wall of the first part 11 form an operation space 4 for the finger to extend into, so as to increase the operation space 4 of the unlocking part 23 and facilitate unlocking. Figure 11 After the mounting plate 2 and the box body 1 are mounted, the first mounting surface 212 faces forward, and the first mounting surface 212 of the mounting plate 2 is attached to the rear surface of the wooden wall 30, the front surface of the box body 1 extends forward from the hole on the wooden wall 30, then the screw penetrates through the mounting plate 2 and is screwed with the wooden wall 30, thereby realizing mounting, and finally the ceramic tile is attached to complete the installation. Figure 12 .

[0073] When mounted on the second fixing part 15, the mounting plate 2 is inserted from back to front, and the mounting plate 2 is rotated in the opposite direction of the first circumferential direction, and after the mounting is completed, the free end of the unlocking part 23 faces backward, and since the force is not blocked by the box body 1, the unlocking is facilitated. Figure 8 After the mounting plate 2 and the box body 1 are mounted with the water pipe, as shown in Figure 9 , the first mounting surface 212 faces backward, and the first mounting surface 212 of the mounting plate 2 is attached to the groove bottom of the solid wall 20, and the front surface of the box body 1 extends forward from the groove of the solid wall 20, then the screw penetrates through the screw through hole 213 of the mounting plate 2 and is screwed with the groove bottom of the solid wall 20, thereby realizing mounting, as shown in Figure 10Because the above structure has a locking function, the screw through hole 213 will not move during the assembly process, making it easy to align with the mounting position on the solid wall 10 or wooden wall 30, thus facilitating assembly.

[0074] Of course, the mounting plate 2 can also be installed with the solid wall 20 and the wooden wall 30 by gluing.

[0075] Example 2

[0076] Unlike Embodiment 1, in this embodiment, the mounting plate 2 is in the same posture when it is mounted on the first fixing part 13 and the second fixing part 15.

[0077] The guide slope 1321, the first anti-rotation surface 1322, and the second anti-rotation surface 1314 of the first fixing part 13 have the same orientation as the guide slope 1321, the first anti-rotation surface 1322, and the second anti-rotation surface 1314 of the second fixing part 15.

[0078] Mounting plate 2 has a second mounting surface 214 and a third mounting surface 215 that are perpendicular to the front-rear direction 40° and opposite to each other. (Reference) Figure 13 When the mounting part 211 is fixed to the first fixing part 13, the front surface of the box body 1, the second mounting surface 214, the third mounting surface 215 and the pipe part 14 are arranged in sequence from front to back; the second mounting surface 214 is used to fit and fix to the wooden wall 30, the pipe part 14 is located behind it, and the pipe connected to the pipe part 14 is also located in the rear direction, thereby achieving concealment. The front surface of the box body 1 is in front of the mounting plate 2, so that it can pass through the hole on the wooden wall 30 and be exposed on the front surface of the wooden wall 30, which is convenient for users to use.

[0079] refer to Figure 14 When the mounting part 211 is fixed to the second fixing part 15, the pipe part 14, the second mounting surface 214 and the third mounting surface 215 are arranged sequentially from front to back. The third mounting surface 215 is flush with the rear surface of the box body 1 or located behind the rear surface of the box body 1. The third mounting surface 215 is attached to the bottom of the groove on the solid wall, which makes it easier to position and install. At the same time, the front surface of the box body 1 can also be exposed on the front surface of the solid wall 20, which is convenient for users.

[0080] In this embodiment, the second mounting surface 214 is always forward, the third mounting surface 215 is always backward, and the mounting plate 2 does not need to consider the scene when assembling, and can be installed in the same posture, but relatively, when the mounting plate 2 has the same unlocking part 23 and flexible locking part 22 as in Embodiment One, its disassembly will be difficult in some cases, for example, when the free end of the unlocking part 23 is all directed backward, when fixed with the second fixed part 15, there is enough space without the obstruction of the box body 1, and disassembly is not a problem, but when fixed with the first fixed part 13, since the free end of the unlocking part 23 is backward, there is a problem that the space between the free end of the unlocking part 23 and the second part 12 is too small to operate, or the pipe part 14 may interfere, and the user needs to put his hand into the space between the pipe part 14 and the free end of the unlocking part 23, which is not easy to operate.

[0081] In addition to the above-mentioned Embodiment One and Embodiment Two, the mounting part 211 can also be screwed with the first fixed part 13 or the second fixed part 15 to realize assembly, so as to realize the assembly of the mounting plate 2 and the first fixed part 13 or the second fixed part 15, for example, the mounting hole is a threaded hole, which is simple and convenient, but relatively, the threaded structure has the risk of reverse rotation and loosening when subjected to a reverse force, and must be provided with another part to prevent reverse loosening, which requires an additional part to prevent loosening, increasing the cost, and in the aspect of preventing loosening, it is not as stable and convenient as the above-mentioned Embodiment One and Embodiment Two.

[0082] The mounting plate 2 can also be directly inserted with the first fixed part 13 or the second fixed part 15 to realize assembly, and the first fixed part 13 and the second fixed part 15 can be provided with an insertion limiting surface to limit the mounting plate, which is simple and convenient.

[0083] The above description of the specification and embodiments is used to explain the protection scope of the present application, but does not constitute a limitation on the protection scope of the present application. Through the inspiration of the present application or the above-mentioned embodiments, the modification, equivalent replacement or other improvement of the embodiments of the present application or one part of the technical features can be obtained by the ordinary skilled in the art combining with the common knowledge, the ordinary technical knowledge in the art and / or the prior art through logical analysis, reasoning or limited test, which should be included in the protection scope of the present application.
