[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the position of the corresponding component or structure in the direction of gravity. Figure 1The directions of the drawings shown. "Inside and outside" refer to the inside and outside of the corresponding component outline. In addition, it should be noted that the terms used, such as "first, second", etc., are to distinguish one element from another and have no order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0031] For ease of understanding, please refer to the attached Figures 1 to 3 , the specific structure and working principle of the drainage riser connector disclosed in the present invention are explained in detail in combination with the embodiments.

[0032] The present disclosure relates to a drainage riser connector, which is used to connect adjacent first drainage risers 4 and second drainage risers 5, so as to avoid the second drainage riser 5 being blocked by the upper receiving interface 61 of the drainage riser below during the connection process, making it difficult to select a suitable length and seal, resulting in leakage. Figure 1 and Figure 2 The drainage riser connector disclosed in the present invention includes a connecting pipe section 1 and a sliding pipe section 2, wherein the connecting pipe section 1 can be detachably connected to and communicated with the first drainage riser 4, and one end of the sliding pipe section 2 is connected to the connecting pipe section 1 and extends downward in a vertical direction for a certain distance to provide a sliding space for the second drainage riser 5.

[0033] When connecting the adjacent first drainage riser 4 and the second drainage riser 5, the connecting pipe section 1 can be first fixedly connected to the first drainage riser 4, and then the upper end of the second drainage riser 5 is placed in the sliding pipe section 2, so that the second drainage riser 5 can slide along the extension direction of the sliding pipe section 2, so as to adjust the position of the second drainage riser 5 in the sliding pipe section 2, and avoid the second drainage riser 5 from interfering with the drainage riser with the socket 61 below. Then, the drainage riser with the socket 61 is placed below the second drainage riser 5. After the placement is completed, the second drainage riser 5 is slid downward in the sliding pipe section 2, so that the end of the second drainage riser 5 is inserted into the socket 61 of the drainage riser below, and the connection can be completed, thereby solving the problem that the position of the drainage riser with the socket below is fixed, and the height of the first drainage pipe 4 above is also fixed, and if the second drainage riser 5 uses a suitable pipe material, the lower end cannot enter the drainage riser with the socket.

[0034] The drainage riser connector of the present invention is provided with a sliding pipe section 2, so that the second drainage riser 5 can be placed in the sliding pipe section 2 and slide upward for a certain distance before installation to avoid interference with the drainage riser with the socket 61 below. After the drainage riser with the socket 61 below is placed, it slides downward along the sliding pipe section 2 to complete the connection, thereby avoiding the interference with the socket 61 of the drainage riser below due to the length of the second drainage riser 5 being too long and making it difficult to connect. Since the length of the second drainage riser 5 is appropriate, after installation, the second drainage riser 5 will not be difficult to seal or leak due to the length of the second drainage riser 5 being too short.

[0035] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A transition pipe 3 is also provided between the connecting pipe section 1 and the sliding pipe section 2. One end of the transition pipe 3 is fixedly connected to the connecting pipe section 1, and the other end is fixedly connected to the sliding pipe section 2. The diameters of the two ends of the transition pipe 3 are smaller than the diameter in the middle, so that the pipe wall of the transition pipe 3 is in an arc shape. By providing the transition pipe 3, on the one hand, the distance that the second drainage riser 5 can slide in the vertical direction can be increased, so that the length of the second drainage riser 5 can be set more flexibly to adapt to different installation conditions. On the other hand, since the pipe wall of the transition pipe 3 is in an arc shape, when the second drainage riser 5 slides in the transition pipe 3, the outer wall of the second drainage riser 5 will not contact the transition pipe 3, thereby reducing the friction between the transition pipe 3 and the outer wall of the second drainage riser 5, and also preventing the second drainage riser 5 from being stuck in the transition pipe 3 due to tilting, shaking, etc.

[0036] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A flow guide 31 is provided on the inner wall of the transition pipe 3. The flow guide 31 can guide the fluid to flow in the transition pipe 3, thereby preventing the fluid from being blocked, swirling and forming a vacuum, and preventing the air flow from being discharged smoothly and causing high noise. Figure 2 In this embodiment, the flow guide 31 is a spiral groove disposed on the inner wall of the transition pipe 3. The spiral groove can guide the flow of the fluid in the transition pipe 3 to avoid the above situation. Of course, in other embodiments, the flow guide 31 can also be a spiral protrusion disposed on the inner wall of the transition pipe 3, or other shapes that can be used for drainage, etc., which can be determined according to actual conditions, such as the length and shape of the transition pipe 3, etc., and the present disclosure does not limit this.

[0037] According to a second aspect of the present disclosure, a drainage riser assembly is further provided, comprising a first drainage riser 4, a second drainage riser 5, a third drainage riser 6, a connection assembly 7, and the drainage riser connector described above. The first drainage riser 4 and the third drainage riser 6 can be connected via the drainage riser connector via the second drainage riser 5, and the connection assembly 7 is used to fix the connection pipe section 1 in the drainage riser connector to the first drainage riser 4.

[0038] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The connection assembly 7 includes a first connection block 71 and a second connection block 72, wherein the first connection block 71 is located in the floor slab and can be fixedly connected to the first drainage riser 4, and the second connection block 72 is fixedly connected to the connection pipe section 1 of the drainage riser connection piece. A first connection groove 711 is provided on the first connection block 71, through which the head of the bolt 8 can be clamped in the first connection block 71, and a second connection groove 721 is provided on the second connection block 72, so that the tail of the bolt 8 can pass through the second connection block 72 and cooperate with the external nut 9 when the first connection block 71 and the second connection block 72 are fixedly connected, thereby completing the fixed connection of the first connection block 71 and the second connection block 72.

[0039] Specifically, the first connection groove 711 includes a first part and a second part. The first part has a wider diameter and is larger than the diameter of the head of the bolt 8. The second part has a narrower diameter and is smaller than the diameter of the head of the bolt 8, but larger than the diameter of the tail of the bolt, so that the bolt 8 can be inserted into the first connection block 71 through the first part, and then slide along the first connection groove 711 to the second part for clamping. When the second connection block 72 is connected, it is only necessary to align the second connection groove 721 with the tail of the bolt 8 and move it upward, so that the tail of the bolt 8 passes through the second connection block 72, and then screw the nut 9 into the tail of the bolt 8, so as to complete the fixed connection between the first connection block 71 and the second connection block 72. Of course, in other embodiments, the connection assembly 7 can also be of other structures, as long as it can play the role of connecting the first drainage riser 4 and the drainage riser connector. The specific structure can be determined according to actual conditions, and the present disclosure does not limit this.

[0040] In one embodiment of the present disclosure, see Figure 2 and Figure 3 A plurality of first connection blocks 71 and second connection blocks 72 are provided, and are evenly distributed along the circumference of the connecting pipe section 1 and the first drainage riser 4. By providing a plurality of first connection blocks 71 and second connection blocks 72, the stability of the connection between the drainage pipe connector and the first drainage riser 4 can be ensured, and leakage of fluid between the drainage pipe connector and the first drainage riser 4 during use and other installation hazards can be avoided.

[0041] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The connection assembly 7 also includes a sealing portion 73. By setting the sealing portion 73, after the drainage riser connector and the first drainage riser 4 are fixedly connected together through the first connection block 71 and the second connection block 72, the connection portion can be sealed to prevent the fluid in the first drainage riser 4 from leaking when flowing through the gap between the first drainage riser 4 and the drainage riser connector, as well as other safety hazards.

[0042] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The sealing portion 73 includes a sealing ring groove 731 located on the opposite side of the first connection block 71 and the second connection block 72, and a sealing member 732 is arranged in the sealing ring groove 731. In this embodiment, the cross section of the sealing ring groove 731 is arc-shaped, and the two oppositely arranged sealing ring grooves 731 enclose a sealing cavity for placing the sealing member 732. The sealing member 732 is located on the outer wall of the end surface of the first drainage riser 4 and the connecting pipe section 1, so as to seal the connection between the first drainage riser 4 and the connecting pipe section 1.

[0043] In other embodiments of the present disclosure, a sealing protrusion 7321 protruding axially along the connecting pipe section 1 may be provided on the sealing member 732, the upper end face of the sealing protrusion 7321 contacts the end face of the first drainage riser 4, and the lower end face contacts the end face of the connecting pipe section 1, and a better sealing effect can be achieved through the cooperation between the sealing protrusion 7321 and the part of the sealing member 732 that is attached to the outer wall of the end face where the first drainage riser 4 and the connecting pipe section 1 are connected. Of course, in other embodiments, the sealing portion 73 may also be of other structures, as long as it can seal the connection between the first drainage riser 4 and the drainage riser connector, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0044] In one embodiment of the present disclosure, see Figure 2 and Figure 3 A plurality of mounting grooves 51 are provided on the outer wall of the second drainage riser 5. The plurality of mounting grooves 51 are arranged at intervals in the vertical direction, and a sealing ring 511 is installed in the mounting groove 51. By providing the mounting grooves 51 and the sealing ring 511, the second drainage riser 5 can play a sealing role after installation, thereby preventing the fluid in the drainage riser from leaking when flowing through the gap between the second drainage riser 5 and the sliding pipe section 2, as well as other safety hazards.

[0045] When assembling the drainage riser assembly of the present disclosure, it is first necessary to connect the drainage riser connector to the first drainage riser 4. The connection process is to first clamp the bolt 8 in the first connection block 71, and then move the connection pipe section 1 with the second connection block 72 upward, so that the tail of the bolt 8 passes through the second connection block 72 and cooperates with the nut 9 to complete the connection between the drainage riser connector and the first drainage riser 4. Then, insert the second drainage riser 5 into the sliding pipe section 2 of the drainage riser connector and slide it upward for a certain distance, and finally place the third drainage riser 6. After the placement is completed, slide the second drainage riser 5 downward to connect with the socket 61 on the third drainage riser 6, and the assembly of the drainage riser assembly can be completed. After the assembly is completed, other sealing and installation work known to those skilled in the art can also be performed, which will not be repeated here.

[0046] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0048] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
