Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a concealed box. Background Art

[0002] The concealed box is a water switch component pre-buried in the wall. It has the effect of hiding the switch body and is loved by many consumers. At present, there are two main types of concealed boxes on the market. One includes a box body and a water-passing part, wherein the water-passing part is a copper part and is mostly installed in the box body by screws. The other includes only a copper water-passing part, and its water-passing joint is formed by rubber coating. The above two concealed box structures both have the problem of heavy weight of the water-passing part (thicker walls are set to increase strength), which leads to high costs. In addition, the first structure has many assembly steps and cumbersome use. The second structure has the problem of rubber coating at the position. Due to the small range of rubber coating, gaps and water leakage are prone to occur. For this reason, the utility model provides a low-cost and quickly installed concealed box. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a concealed box structure which is low in cost and can be quickly installed.

[0004] A concealed box, comprising a water-permeable core body and a covering box body, wherein:

[0005] The water flow core body comprises a connected valve core installation cavity, a water inlet joint and a water outlet joint. The valve core installation cavity is used to install the valve core, and the water inlet joint and the water outlet joint are used to install an external water flow pipe.

[0006] The covering box body is formed on the outside of the water passing core body by means of rubber coating, and leaves the installation openings of the valve core installation cavity, the water inlet joint and the water outlet joint free to avoid being unable to use.

[0007] The concealed box provided by the utility model adopts a rubber-coated method to inject and shape the covering box body on the outside of the water-passing core body, which not only reduces the steps required for installation when the concealed box is used and improves the convenience and quickness of use, but also allows the covering box body to strengthen the strength of the water-passing core body through the rubber-coated method, so that the wall thickness of the water-passing core body can be made thinner, thereby reducing the use of high-cost materials and reducing the cost of the concealed box.

[0008] Preferably, the water flow core includes two mounting seats, the valve core mounting cavity includes a temperature control mounting cavity and a flow cutting mounting cavity, and is respectively arranged on the two mounting seats.

On the one hand, the material used for the water flow core body can be reduced, and on the other hand, the relative limiting effect between the water flow core body and the covering box body can be improved, especially at the position where the valve core is installed, to avoid looseness between the covering box body and the water flow core body during subsequent use.

[0012] Preferably, the covering box body is provided with an extension hole in the extension direction of the screw hole of the water core body. When the screw fixing the valve core pressure cover is screwed into the screw hole, the exceeding part enters the extension hole, which can prevent the screw from pressing against the covering box body and prevent the screw from pushing open the covering box body and the water core body.

[0013] Preferably, the base of the covering box body is provided with an extending mounting ear, and the mounting ear is provided with a mounting hole for installing the concealed box in the embedded space.

[0014] Preferably, an outer ring in the middle of the covering box body is provided with an extending assembly ear, and the assembly ear is provided with an assembly hole to provide an installation and fixing position for the closing cover of the covering box body.

[0015] Preferably, the bottom and / or the periphery of the covering box body are provided with a hollowing out for reducing weight, which can not only reduce the weight of the concealed box but also reduce the material cost.

[0016] Preferably, the covering box body forms a mounting groove on the surface where the mounting opening of the valve core mounting cavity is located, and an annular groove for mounting a sealing ring is provided on the outer periphery of the mounting groove.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] The concealed box provided by the utility model adopts a coating method to be injection-molded and formed on the outside of the water-passing core body, which not only reduces the steps required for installation when the concealed box is used, and improves the convenience and quickness of use, but also allows the coating box body to strengthen the strength of the water-passing core body through the coating method, so that the wall thickness of the water-passing core body can be made thinner, thereby reducing the use of high-cost materials, and reducing the cost of the concealed box;

[0019] The water-passing core is an integrally formed metal part with high overall strength;

[0020] The periphery of the mounting plate is provided with a notch, and the covering box body forms a limiting protrusion at the notch position, which can reduce the material of the water-passing core body on the one hand, and improve the relative limiting effect between the water-passing core body and the covering box body on the other hand, especially at the position where the valve core is installed, to avoid the loosening between the covering box body and the water-passing core body during subsequent use;

[0021] The covering box body is provided with an extension hole in the extension direction of the screw hole of the water passing core body. When the screw fixing the valve core gland is screwed into the screw hole, the protruding part enters the extension hole, which can prevent the screw from pressing against the covering box body and prevent the screw from pushing open the covering box body and the water passing core body.

[0022] The bottom and / or the periphery of the covering box body are provided with a hollowing out for reducing weight, which can not only reduce the weight of the concealed box, but also reduce the material cost. BRIEF DESCRIPTION OF THE DRAWINGS
