Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a rotary connector for a drain. Background Art

[0002] A drain is a drainage device used for a bathtub, a vegetable sink or a kitchen sink. The outlet of the drain is usually connected to a drain pipe and a sewage pipe outlet.

[0003] Before purchasing a drain seat and connector, users often find it difficult to determine whether they need horizontal drainage or downward drainage. Existing fixed drain connectors are usually suitable for either horizontal drainage or downward drainage. As shown in the Chinese utility model patent with patent publication number CN221855694U and patent name "Deodorant Drain", it includes a drain seat with a connector threaded on one side of the drain seat. The end of the connector away from the drain seat is fixedly connected to a drain pipe. This structure facilitates the horizontal discharge of wastewater, but is less suitable for downward drainage. For downward drainage, the drain pipe needs to be bent vertically downward. After installation, the drain pipe can only be bent vertically downward. Existing drain pipes are easily deformed or drooped and shifted during use after bending, making it difficult to maintain the initially adjusted position. Sewage easily accumulates at the outlet of the connector and the deformed elbow of the drain pipe, which is not conducive to the smooth discharge of wastewater. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a drain rotary connector, which is provided with a connecting seat and a rotating connecting elbow that can rotate relative to each other and maintain the rotation angle position. It is easy to install and use, can better connect the drain and the sewage pipe outlet, ensure that the wastewater discharged from the drain can be discharged smoothly, and an odor-proof baffle is provided in the connector to prevent back-odor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rotary connection part for a water drain comprises a connecting seat and a rotary connection elbow, characterized in that: a connecting ring is provided on the connecting seat, the connecting ring is used to be connected to the water drain, a water outlet connection port is provided on the side of the connecting seat, an odor-proof baffle is provided in the water outlet connection port, a sealing ring and a mounting flange are provided outside the water outlet connection port, a sealing ring is provided in the sealing ring, a connecting sleeve and a positioning flange are provided at one end of the rotary connection elbow, the connecting sleeve is rotatably arranged outside the sealing ring and is sealed and connected by the sealing ring, and a connecting thread is provided at the other end of the rotary connection elbow.

[0007] Furthermore, a positioning hole is provided in the mounting flange, a spring and a positioning pin are provided in the positioning hole, a circle of evenly arranged positioning grooves is provided on the positioning flange, and the spring pushes the head of the positioning pin to fit into the positioning groove to enable the rotating connecting elbow to maintain a relative rotation angle with the connecting seat.

[0008] Furthermore, the end of the water outlet connection port is provided with a positioning groove and a positioning ring, the positioning ring is provided with two notches, and the connecting sleeve is provided with two positioning protrusions. After the positioning protrusions are inserted into the notches, the rotation angle in the positioning groove deviates from the notches to limit the separation of the connecting seat and the rotating connecting elbow.

[0009] Furthermore, the two notches are symmetrically arranged on the positioning clamp ring.

[0010] Furthermore, two partition mounting seats are provided in the water outlet connection port, mounting holes are provided on the partition mounting seats, and ear shafts corresponding to and matching the mounting holes are provided on the odor-proof partition.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] See also Figure 1-6 As shown, a rotary connector for a drain comprises a connecting seat 1 and a rotary connecting elbow 2. The connecting seat 1 is provided with a connecting ring 11, and the connecting ring 11 is used to be connected to the drain. A water outlet connecting port 12 is provided on the side of the connecting seat 1, and an odor-proof baffle 3 is provided in the water outlet connecting port 12. The odor-proof baffle 3 prevents the occurrence of odor return. A sealing ring 13 and a mounting flange 14 are provided outside the water outlet connecting port 12, and a sealing ring 4 is provided in the sealing ring 13 to ensure that the connection is sealed to avoid overflow. A connecting sleeve 21 and a positioning flange 22 are provided at one end of the rotary connecting elbow 2. The connecting sleeve 21 is rotatably arranged outside the sealing ring 13 and is sealed and connected through the sealing ring 4. A connecting thread 24 is provided at the other end of the rotary connecting elbow 2 for easy sealing connection with the drain pipe. The rotary connecting elbow 2 is used to avoid excessive bending of the drain pipe, which is conducive to smooth discharge of waste water.

[0026] The mounting flange 14 is provided with a positioning hole 15, in which a spring 5 and a positioning pin 6 are installed. The positioning flange 22 is provided with a circle of evenly spaced positioning grooves 23. When no external rotational force acts on the rotating connecting elbow 2, the spring 5 pushes the head of the positioning pin 6 into the positioning groove 23 to enable the rotating connecting elbow 2 to maintain the relative rotation angle with the connecting base 1. During installation, users can flexibly choose horizontal or vertical installation according to the spatial layout. The rotating connecting elbow 2 can be arbitrarily changed in direction relative to the connecting base 1, making the installation of the entire drainage system more flexible and adaptable.

[0027] The end of the water outlet connection port 12 is provided with a positioning groove 16 and a positioning snap ring 17, and the positioning snap ring 17 is provided with two symmetrically arranged notches 18. The connecting sleeve 21 is provided with two positioning protrusions 25. After the positioning protrusions 25 are inserted into the notches 18, they are rotated in the positioning groove 16 to deviate from the notches 18. Using the positioning snap ring 17 to block the positioning protrusions 25 can limit the separation of the connecting seat 1 and the rotating connecting elbow 2 from each other, ensuring that the connecting seat 1 and the rotating connecting elbow 2 will not loosen during operation.

[0028] The water outlet connection port 12 is provided with two baffle mounting brackets 19, each with mounting holes 191. The odor-proof baffle 3 is provided with trunnions 31 that correspond to the mounting holes 191. To ensure that the odor-proof baffle 3 is securely mounted on the water outlet connection port 12, each trunnion 31 is designed to be inserted into a corresponding mounting hole 191, allowing for easy removal and replacement of the odor-proof baffle 3 when necessary. This design not only improves the product's maintenance convenience, but also ensures that the odor-proof baffle 3 will not easily fall off during use, effectively preventing the backflow of sewer odors. To further enhance the deodorizing effect.

[0029] The water outlet connection port 12 is provided with a sealing step 121 that dynamically seals with the odor-proof baffle 3. The sealing step 121 is designed to be inclined toward the outside of the outlet to facilitate the sealing surface of the odor-proof baffle 3 to fit therewith to ensure a sealing effect.

[0030] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
