Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom, more specifically, it relates to a new structure's closestool cement flange. BACKGROUND

[0002] Traditional closestool installation usually relies on a flange ring (also known as a sealing ring or gasket) to achieve connection and sealing with the sewer pipe. The main function of the flange ring is to prevent sewage leakage and odor upwelling, and at the same time, it positions the closestool during installation to avoid the sewage outlet from deviating from the sewage pipe. During installation, cement needs to be applied on both the upper and lower sides of the flange ring, and after the flange ring is fixed at the bottom of the closestool, the flange ring is inserted into the sewage pipe.

[0003] However, the traditional flange ring is usually made of wax or high polymer material, and under the condition of being squeezed with great force, it may be damaged, affecting its sealing performance. In addition, due to the lack of sufficient deformation space, the flange ring cannot effectively disperse the force when it is under pressure, resulting in insufficient shock resistance and poor durability.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arrange", "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] A new structure of toilet cement flange, as shown in Figure 1 and Figure 2 , including a cylindrical flange body 1, a sewage passage 2 for connecting the toilet drain and the sewage pipeline is arranged in the flange body 1, the flange body 1 bottom protrudes a connecting pipe 3, the connecting pipe 3 is used to penetrate into the sewage pipeline, the peripheral side of the flange body 1 is provided with an adhesive ring 4, the upper end face of the adhesive ring 4 is connected with the bottom of the toilet through the cement 12, the lower end face of the adhesive ring 4 is connected with the ground around the sewage pipeline through the cement 12, realizing the connection of the toilet bottom and the sewage pipeline, the sewage flows into the sewage pipeline after passing through the sewage passage 2 and the connecting pipe 3, the cement adopts butyl rubber.

[0028] A ring groove 5 is formed on the peripheral wall of the adhesive ring 4, the ring groove 5 is formed from the outermost side of the adhesive ring 4 to the inside, so that when the adhesive ring 4 is extruded by external force, it can be elastically deformed in the area of the ring groove 5, increasing the flexibility of the flange ring, so that it can better absorb and disperse the impact force when facing the uneven or slight vibration of the toilet bottom, thereby avoiding damage caused by excessive extrusion of the material.

[0029] While a deeper groove 5 improves elasticity, it also leads to excessive deformation of the adhesive ring 4 under pressure, affecting its structural strength. Therefore, the width of the groove 5 is set to be less than half the width of the adhesive ring 4. This design balances the relationship between elastic deformation and structural strength, ensuring the stability and durability of the flange ring during use.

[0030] The upper end of the adhesive ring 4 has a downward-facing groove 6, which runs around the circumference of the adhesive ring 4. A first frosted surface 9 is provided at the bottom of the groove 6, covering the bottom of the groove 6. A second frosted surface 10 is provided at the lower end of the adhesive ring 4, covering the lower end of the adhesive ring 4. By providing the first frosted surface 9 and the second frosted surface 10, the friction between the upper and lower end surfaces of the adhesive ring 4 and the adhesive putty 12 is increased, making the adhesive putty 12 less likely to fall off.

[0031] A connecting groove 7 is formed at the bottom of the groove 6, running along the axial direction of the adhesive ring 4. The connecting groove 7 is located at the bottom of the groove 6 near the drain channel 2. Several reinforcing ribs 8 are evenly spaced within the connecting groove 7, dividing it into several compartments. Adhesive mortar 12 can be filled into the connecting groove 7 to further enhance the connection with the upper surface of the adhesive ring 4. Since the connecting pipe 3 at the bottom of the flange ring penetrates the drain pipe for positioning, the flange ring is less likely to deviate or detach from the ground. However, since the top of the flange ring is only fixed to the toilet by adhesive mortar 12, the connection between the adhesive mortar 12 and the upper surface of the adhesive ring 4 requires even higher precision.

[0032] A sealing ring 11 is provided on the periphery of the connecting pipe 3. The sealing ring 11 is coaxial with the connecting pipe 3 and is integrally formed with the connecting pipe 3. When the connecting pipe 3 is inserted into the sewage pipe, the sealing ring 11 is press-fitted with the inner wall of the sewage pipe, which increases the sealing between the connecting pipe 3 and the sewage pipe, preventing water leakage and backflow of odor.

[0033] At least two sealing rings 11 are provided on the periphery of the connecting pipe 3. Multiple sealing rings 11 are arranged in a vertical direction. An O-ring is provided between adjacent sealing rings 11. The O-ring is an elastic rubber ring that is directly fitted between two sealing rings 11 and is deformed by compression to increase the sealing performance.

[0034] In this embodiment, the connecting pipe 3 is coaxially arranged with the flange body 1, and the connecting pipe 3 and the flange body 1 are integrally formed. The sewage discharge channel 2 is connected to the connecting pipe 3. The connection between the sewage discharge channel 2 and the connecting pipe 3 is inclined downward so that sewage is not easy to remain at the connection.

[0035] like Figure 3 and Figure 4As shown, in this embodiment, the ratio between the width L1 of the annular groove 5 and the width L2 of the adhesive ring 4 is 5 to 13.8, which maximizes its performance. The annular groove 5 can be opened according to this ratio when the size of the flange ring increases or decreases.

[0036] In this embodiment, the ratio between the height of the annular groove 5 and the thickness of the adhesive ring 4 is 3 to 7.5. Furthermore, in the thickness of the adhesive ring 4, the ratio of the upper part H1 of the annular groove 5, the height H2 of the annular groove 5, and the lower part H3 of the annular groove 5 is 3 to 3 to 1.5. Since the upper end face of the adhesive ring 4 needs to be provided with a groove 6, the upper part of the annular groove 5 will be thicker than the lower part of the annular groove 5.

[0037] The installation process of this utility model is as follows:

[0038] like Figure 5 As shown, glue 12 is connected to the upper and lower end faces of the adhesive ring 4 respectively. The sewage channel 2 of the flange body 1 is aligned with the sewage pipe at the bottom of the toilet. The flange ring is fixed to the bottom of the toilet by pressing hard. Then the connecting pipe 3 at the bottom of the flange body 1 is aligned and inserted into the sewage pipe. Finally, glue 12 is filled at the edge of the bottom of the toilet.

[0039] 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 design concept of the present utility model should be included within the protection scope of the present utility model.
