Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0019] Referring to the accompanying drawings, a valve body mounting structure for a concealed panel includes a concealed housing assembly, within which a valve body 10 is installed. It also includes a knob 20 adapted to the concealed housing assembly. A valve stem 11, capable of controlling the valve body, is provided on the outer periphery of the valve body. The knob, in conjunction with the valve stem, rotates the valve stem to control the valve body's operation, such as flow control. A protruding mating portion 21 is provided on the inner periphery of one end of the knob that extends into the concealed housing assembly. This mating portion engages with the valve stem to control the valve body. A clearance space is formed between the inner periphery of the knob facing the other end of the mating portion and the valve stem. This clearance space can be a recessed portion 30 on the inner periphery of the knob, which can be a relatively convex portion. Regarding the mating parts, this utility model mainly utilizes the principle of inner convex and outer concave (based on the inner and outer sides of the wall) to allow the innermost end of the knob to mate with the valve stem. This mating can be achieved using threads or keyways, enabling the knob to drive the valve stem to rotate. A small gap can exist between the mating parts and the valve stem. A larger clearance (which can be called a large gap) is formed between the inner circumference of the knob and the valve stem, excluding the mating parts. This ensures that even if the knob and valve stem are not highly coaxial, the clearance allows the knob to be inserted into the outer circumference of the valve body, preventing interference between the valve stem and the knob. Simultaneously, it ensures the coaxiality of the panel 41 of the concealed box assembly and the knob, guaranteeing that the overall appearance after installation will not exhibit any tilting or other inconsistencies.

[0020] Furthermore, the panel 41 and bushing 42 that cooperate with the recessed box assembly also include the box body (not shown in the figure) placed inside the wall. The knob can be fitted onto the inner circumference of the bushing, and the bushing can engage with the knob. The knob has a locking interface 22 on the side wall inside the recessed box assembly, and the inner circumference of the bushing has a locking protrusion 43 that can engage with the locking interface. The inner side of the snap-fit ​​protrusion is provided with a first guide slope 44, and the outer periphery of the knob is provided with a second guide slope 23 that can be adapted to the first guide slope. In one embodiment, the periphery of the bushing can be composed of multiple pieces. The snap-fit ​​protrusion is located on the inner periphery of the pieces. The pieces can deform when subjected to force, and the inner periphery of the pieces can be attached to the outer periphery of the knob. When the knob is installed, the first guide slope and the second guide slope abut against each other, causing the pieces to deform and expand outward until the snap-fit ​​protrusion is located at the snap-fit ​​interface. Due to the springback property of the pieces themselves, the snap-fit ​​protrusion snaps into the snap-fit ​​interface, realizing the mating connection between the knob and the bushing.

[0021] Preferably, the mating part is located radially inside the second guide slope. Referring to the accompanying drawings, the mating part and the second guide slope are located inside the card interface.

[0022] More specifically, this invention addresses the following: After the valve body is installed in the concealed mounting box, the connection point between the knob on the panel and the valve stem of the valve body has only a small size and clearance. This means that the mating part engages or mates with the valve stem. However, the outer end of the valve stem, where the valve stem might interfere with the knob due to the valve body's tilted installation, has been given ample space to allow for this clearance. If the concealed mounting box is tilted horizontally or vertically relative to the wall, this small gap ensures a normal connection, allowing the knob to drive the valve stem and control the valve body. The ample clearance prevents interference between the valve stem and the knob, thus ensuring proper assembly and rotation of the knob and valve body.

[0023] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
