Description

Technical Field

[0001] This utility model relates to the field of rain-pre-embedded box technology, specifically to an adjustable pre-embedded box kit. Background Technology

[0002] In interior decoration, in order to pursue aesthetics and save space, consumers generally prefer to choose concealed shower heads in the bathroom shower area. This type of shower system embeds the pre-installed box with water flow function into the wall in advance, and only the control components such as the switch valve core and the switching valve core are exposed on the outside of the wall, thus achieving visual simplicity and integrity.

[0003] However, traditional pre-embedded boxes present several problems during construction. First, if the plumbing installers and tile installers do not fully coordinate when the box is installed in the wall, the installation depth may exceed the preset range, causing significant inconvenience for subsequent maintenance and replacement.

[0004] In existing technologies, concealed installation boxes for bathroom products are typically fixed directly to the bottom of the wall using expansion self-tapping screws. However, actual installation environments are complex and diverse, such as solid walls, hollow walls, or walls with mounting brackets, making a single wall-based fixing method unsuitable for widespread application. Construction workers often need to use other materials on-site for auxiliary fixing, which can easily lead to the following problems: the installation depth cannot be precisely controlled within the design range; the installation level is difficult to guarantee; the fixing stability is insufficient; and uneven stress causes the force to concentrate on the connection between the pipe and the main water-passing structure, posing a risk of joint leakage under long-term use.

[0005] Furthermore, if the customer's wall is thin, or if water pipes, electrical conduits, or other pipelines are pre-embedded at the bottom of the wall, using expansion self-tapping screws for bottom fixing can easily penetrate the wall or damage the internal pipelines, causing unnecessary economic losses. For walls that are too deep, there are also difficulties in installation.

[0006] Another common problem occurs during the wall tiling stage. After the embedded box is fixed at the bottom of the wall, the installer needs to cut the outer cover to make the outer edge of the embedded box flush with the tile surface. If this cutting process is not done properly, it is very easy to damage the water-passing body inside the embedded box or scratch the tile surface.

[0007] Meanwhile, the internal structure of traditional pre-embedded boxes typically relies on a large number of screws and inserts for fixation, resulting in significant space occupation. When after-sales maintenance is required, these components interfere with the disassembly and maintenance of the main water-passing structure, further increasing the difficulty of repair.

[0008] Therefore, there is currently no effective solution to the above problems. Utility Model Content

[0009] In view of the above-mentioned technical problems in related technologies, this utility model proposes an adjustable component pre-embedded box kit, which can overcome the above-mentioned shortcomings of the prior art.

[0010] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: An adjustable pre-embedded box kit includes a pre-embedded base plate, a pre-embedded outer shell, and a pre-embedded top cover. The pre-embedded base plate is snap-fitted to the inner end of the pre-embedded outer shell. The side of the pre-embedded component formed by the pre-embedded base plate and the pre-embedded outer shell is provided with a hole for the water-passing body to pass through. The opening of the pre-embedded outer shell is detachably connected to the pre-embedded top cover. The pre-embedded outer shell is provided with guide mounting structures at the four corners of the connection with the pre-embedded top cover. Each guide mounting structure has several fixed teeth perpendicular to the installation direction at its bottom end.

[0011] Furthermore, the embedded base plate is provided with rear mounting screw holes at its four corners, and rear locking structures are provided on both sides of the embedded base plate. Both the ends of the rear mounting screw holes and the ends of the rear locking structures are provided with undercut structures. The embedded outer shell is provided with undercut locking screw holes at its four corners that match the rear mounting screw holes, and the embedded outer shell is provided with undercut locking holes on both sides that match the rear locking structures.

[0012] Furthermore, when the pre-embedded box is installed later, the later installation screw hole and the undercut locking screw hole are fixed to the wall with screws.

[0013] Furthermore, when the pre-embedded box is pre-installed, the pre-embedded outer shell is sleeved on the outside of the fixed tooth position with the pre-installed mounting plate. The four corners of the pre-installed mounting plate extend out of the pre-installed mounting screw holes, and the pre-embedded box is fixed to the wall through the pre-installed mounting screw holes.

[0014] Furthermore, the front mounting plate is provided with height adjustment teeth at its front end, and the front mounting plate is fixedly engaged with the fixed teeth of the pre-embedded housing through the height adjustment teeth.

[0015] Furthermore, the four corners of the pre-embedded cover are provided with guide mounting positions that match the guide mounting structure.

[0016] Furthermore, the pre-embedded cover is also provided with a level position for installing a level.

[0017] The beneficial effects of this utility model are as follows: The pre-embedded base plate and the outer shell are connected by a snap-fit ​​mechanism, simplifying the structure and reducing the use of screws. Through the combination of the guide installation structure, fixed tooth positions, and a detachable front mounting plate, two installation methods (front and rear) and flexible adjustment of the installation depth are achieved, thus adapting to various wall types, avoiding damage to pipelines, and ensuring stable installation. The rational design of the overall structure ensures even distribution of stress, reducing the risk of leakage at pipe joints, ultimately achieving a comprehensive effect of convenient installation, strong adaptability, and high safety and reliability.

The opening of the pre-embedded outer shell 2 is detachably connected to the pre-embedded upper cover 4. The pre-embedded outer shell 2 is provided with guide installation structures 203 at the four corners of the connection with the pre-embedded upper cover 4. Each guide installation structure 203 is provided with a plurality of fixed teeth 204 perpendicular to the installation direction at its bottom end.

[0022] In this embodiment, the four corners of the embedded base plate 1 are provided with rear mounting screw holes 101, and the two sides of the embedded base plate 1 are provided with rear locking structures 102. The ends of the rear mounting screw holes 101 and the ends of the rear locking structures 102 are provided with undercut structures. The four corners of the embedded outer shell 2 are provided with undercut locking screw holes 201 that match the rear mounting screw holes 101, and the two sides of the embedded outer shell 2 are provided with undercut locking holes 202 that match the rear locking structures 102.

[0023] In this embodiment, when the pre-embedded box is installed later, the later installation screw hole 101 and the inverted snap-fit ​​screw hole 201 are fixed to the wall by screws.

[0024] In this embodiment, when the pre-embedded box is pre-installed, the pre-embedded outer shell 2 is sleeved on the outside of the fixed tooth position 204 with the pre-installed mounting plate 3. The four corners of the pre-installed mounting plate 3 extend out of the pre-installed mounting screw holes 301, and the pre-embedded box is fixed to the wall through the pre-installed mounting screw holes 301.

[0025] In this embodiment, the front mounting plate 3 is provided with an adjustment height tooth 302 at its front end, and the front mounting plate 3 is fixedly engaged with the fixed tooth 204 of the pre-embedded housing 2 through the adjustment height tooth 302.

[0026] In this embodiment, the four corners of the pre-embedded top cover 4 are provided with guide mounting positions 401 that match the guide mounting structure 203.

[0027] In this embodiment, the pre-embedded cover 4 is also provided with a level position 402 for installing a level.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0029] In practical use, according to the adjustable component pre-embedded box kit of this utility model, the four corners of the pre-embedded base plate are provided with rear-mounted mounting screw holes. These rear-mounted screw holes are designed with an inverted snap-fit ​​structure, serving as connection holes to fix the pre-embedded base plate and the pre-embedded outer shell, eliminating the need for screws and inserts in conventional pre-embedded boxes. The pre-embedded base plate and the pre-embedded outer shell are fixed together using a combination of the inverted snap-fit ​​structure and the locking structure. When the pre-embedded box is installed rear-mounted, the screws pass through the rear-mounted screw holes, fixing the pre-embedded base plate to the wall while simultaneously fixing the pre-embedded outer shell to the pre-embedded base plate.

[0030] The four corners of the pre-embedded outer shell correspond to the pre-embedded base plate, and are designed with inverted locking holes to assist in the installation of the screw holes with an inverted locking structure. Inverted locking positions are also designed on both sides of the pre-embedded outer shell to assist in fixing the pre-embedded base plate and the pre-embedded outer shell, eliminating the need for screws and inserts. The interior of the pre-embedded box kit, apart from the main water-passing body, has no other space-consuming components, ensuring no interference for customers during after-sales service. The opening of the pre-embedded outer shell has an installation position for guiding the installation of the pre-embedded top cover.

[0031] The pre-embedded outer shell and pre-embedded top cover are precisely designed and divided in size. Within the adjustable depth range of the design, after tiling the wall, the pre-embedded top cover can be removed directly without cutting the pre-embedded outer shell. If the customer's pre-embedded depth is too shallow, a portion is also reserved for cutting the pre-embedded outer shell to the required size.

[0032] The front of the pre-embedded cover is designed with a level position. The level placed there will help the installers adjust the horizontal position according to the level markings during the installation process.

[0033] The pre-embedded top cover is equipped with a guide mounting position, the size of which fits tightly with the pre-embedded outer shell. The guide mounting position of the pre-embedded top cover can be inserted into the pre-embedded outer shell. The guide mounting position is designed with fixed teeth, so it is not easy to fall out. At the same time, it is convenient for installers to remove after installation.

[0034] While retaining the standard rear-mounting design, an optional front-mounting mode is also available. A front-mounting plate is designed, with adjustable height teeth at its four lower corners creating a movable space between it and the fixed teeth at the four corners of the pre-embedded housing, allowing for adjustment of the installation depth. The front-mounting plate extends from its four corners with front-mounting screw holes, making it suitable for various installation environments, including solid walls, hollow walls, or wall-mounted brackets. Two installation methods are available for customers to choose from on one type of pre-embedded box.

[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, the structure is simplified and the use of screws is reduced through the snap-fit ​​connection between the pre-embedded base plate and the outer shell. The combination of the guide installation structure, fixed tooth position, and detachable front mounting plate allows for flexible adjustment of both front and rear installation methods and installation depth, thus adapting to various wall types, avoiding damage to pipelines, and ensuring stable installation. The rational design of the overall structure ensures even distribution of stress, thereby reducing the risk of leakage at pipe joints, ultimately achieving a comprehensive effect of convenient installation, strong adaptability, and high safety and reliability.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
