Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a flush-mounted box with a test protection function. Background Art

[0002] When installing the flush-mounted box, it needs to be installed into a preset hole in the wall, and generally, the embedded hole is then covered by a decorative cover to form an invisible installation effect of the faucet control switch. Since the flush-mounted box is installed by embedding, the installation difficulty is relatively large and it is not easy to maintain. Therefore, after many flush-mounted boxes are installed, high-pressure water is introduced for testing to test the installation tightness and ensure that there will be no water leakage problem during subsequent use. However, during the test, the high-pressure water may damage the valve core, which will bring a poor product quality experience to consumers. Therefore, the utility model provides a flush-mounted box structure with a test protection function to solve the above technical problems. Content of the Utility Model

[0003] The utility model provides a flush-mounted box structure with a test protection function to solve the above technical problems.

[0004] A flush-mounted box with a test protection function includes a flush-mounted box body and a test protection cover. Specifically,

[0005] The flush-mounted box body is provided with a valve core installation cavity for installing a valve core, and the valve core installation cavity is provided with an installation opening for the valve core to be inserted.

[0006] In the test stage, after the flush-mounted box body is installed into the embedded opening, the test protection cover is installed on the flush-mounted box body and blocks the installation opening. At this time, a closed space is formed between the flush-mounted box body and the water supply pipeline, and the flush-mounted box body can be tested by high-pressure water to check whether it is assembled in place and whether there is water leakage. If no water leakage is detected, the test protection cover can be removed and the valve core assembly can be installed to complete the assembly of the flush-mounted box.

[0007] The flush-mounted box provided by the utility model is equipped with a test protection cover, which can replace the valve core to block the installation opening of the valve core installation cavity when the flush-mounted box is subjected to a sealing test, thus avoiding damage to the valve core during the high-pressure test of the flush-mounted box. On the other hand, the valve core can also avoid the high-pressure test and extend its service life.

[0008] Preferably, the test protection cover is locked on the flush-mounted box body by screws, and the installation is firm and reliable.

[0009] Preferably, four screw holes are provided around the installation opening, and the four sides of the test protection cover are locked on the screw holes around the installation opening by four screws. The locking force is uniform, which can avoid water leakage of the test protection cover during the test.

[0010] Preferably, the test protection cover includes a pressing plate and a plug. The pressing plate seals the end of the installation opening, and the plug extends into the installation opening to improve the sealing degree of the installation opening.

[0011] Preferably, an annular groove is provided on the periphery of the plug, and a sealing ring is sleeved in the annular groove to further reduce the water leakage at the installation position of the test protection cover.

[0012] Preferably, a hollowing is provided at one end of the test protection cover away from the installation cavity, which can reduce the weight and material cost of the test protection cover.

[0013] Preferably, a cross-shaped reinforcing rib is provided in the hollowing of the test protection cover to strengthen the strength of the test protection cover.

[0014] Preferably, to avoid the situation of water leakage due to the insecure installation of the test protection cover, a test sealing cover is further included. The test sealing cover seals the concealed installation box body and seals the test protection cover, thereby forming a second seal to avoid the situation of water spraying during the test.

[0015] Preferably, the test sealing cover is locked on the concealed installation box body by screws, with high sealing performance.

[0016] Preferably, the test sealing cover is a transparent shell, through which the internal test situation can be observed in real time, whether the test protection cover leaks water, and where the end face of the concealed installation box body leaks water.

[0017] Preferably, a valve core assembly is further included. The valve core assembly includes a valve core, a pressing seat, a decorative plate and a handle. After the sealing test is completed, the test protection cover is disassembled, the valve core is installed in the valve core installation cavity, and is pressed and fixed by the pressing seat. The decorative plate seals the concealed installation box body and is provided with a relief hole for the pressing seat, and the handle is connected to the valve rod of the valve core.

[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0019] The concealed installation box provided by the present invention is provided with a test protection cover, which can replace the valve core to block the installation opening of the valve core installation cavity when the concealed installation box is subjected to a sealing test, thereby avoiding the situation of damaging the valve core when the concealed installation box is subjected to a high-pressure test. On the other hand, the valve core can also avoid high-pressure tests and extend its service life;

[0020] The test protection cover is locked on the concealed installation box body by screws, with firm and reliable installation. At the same time, the same set of screw holes can also be used for the valve core assembly, reducing the design of the assembly structure;

[0021] One end of the test protection cover away from the installation cavity is provided with a hollowing-out, which can reduce the weight and material cost of the test protection cover. At the same time, a cross-shaped reinforcing rib is also adopted to strengthen the strength of the test protection cover;

[0022] A test sealing cover is also equipped to prevent the situation of water leakage or water spraying caused by the insecure installation of the test protection cover. Brief Description of the Drawings
