Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a drain device. Background Technology

[0002] A drain assembly generally refers to a drainage device installed on a washbasin. The drain assembly mainly includes a water outlet base, a connecting base, and an outer sleeve. The water outlet base usually has a threaded straight pipe integrally formed, which connects to the connecting base for locking and positioning. However, the current outer sleeve is generally integrally formed with the connecting base. After installation, the water pipe is installed on the outer sleeve. When disassembling, the water pipe needs to be removed first, which is inconvenient, affects the efficiency of disassembly and assembly, and is not convenient for subsequent maintenance and initial installation. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a drain device.

[0004] To achieve the above objectives, the present invention provides a drain device, comprising: a water outlet seat inserted into a drain outlet, an outer sleeve rotatably mounted on the water outlet seat via a positioning device, and a drain pipe mounted on the side wall of the outer sleeve.

[0005] A further improvement is made to the positioning device, which includes a connecting pipe threaded to the water outlet seat, an abutment plate disposed at the bottom of the connecting pipe, an outer sleeve sleeved on the connecting pipe, one end abutting against the abutment plate and the other end abutting against the outer wall of the drain outlet, a first sealing ring being disposed between the abutment plate and the outer sleeve, and a water outlet being disposed between the connecting pipe and the abutment plate.

[0006] A further improvement is that the abutment plate is also provided with a limiting platform that matches the outer sleeve.

[0007] A further improvement is that the limiting platform is also equipped with an anti-slip strip for the connecting pipe, which is easy to twist.

[0008] A further improvement is that the height of the drain pipe is located above the water outlet to form a water cover.

[0009] A further improvement is that the outer tube is also provided with a limiting ring that matches the outer tube, and several reinforcing ribs are provided between the limiting ring and the outer tube.

[0010] A further improvement is that the height of the connecting tube is higher than the height of the outer tube.

[0011] A further improvement is that the drain pipe is also equipped with a rotatable guide elbow.

[0012] A further improvement is that: a connecting sleeve is locked onto the drain pipe, a first engaging ring is provided on the connecting sleeve, a second engaging ring is provided on the guide elbow to engage with the first engaging ring, and a second sealing ring is also provided between the guide elbow and the drain pipe.

[0013] The advantages and beneficial effects of this utility model are as follows: With a simple structure and convenient use, the outer sleeve and the drain itself are positioned by connecting the connecting pipe to the water outlet seat. During installation and disassembly, there is no need to rotate the outer sleeve, which improves the convenience of installation, greatly improves the installation efficiency, and reduces the space occupied by the drain. Moreover, the outer sleeve can be rotated after being positioned, which improves the functionality of the drain. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figures 1-4 As shown, a drain device includes: a water outlet seat 101 inserted into a drain outlet, an outer sleeve 102 rotatably mounted on the water outlet seat 101 via a positioning device, and a drain pipe 103 mounted on the side wall of the outer sleeve 102.

[0017] To facilitate the installation of the outer sleeve 102 and the positioning drain, the positioning device includes: a connecting pipe 104 threadedly connected to the outlet seat 101, and an abutment plate 105 disposed at the bottom of the connecting pipe 104. The outer sleeve 102 is sleeved on the connecting pipe 104, with one end abutting against the abutment plate 105 and the other end abutting against the outer wall of the drain outlet. A first sealing ring 106 is also provided between the abutment plate 105 and the outer sleeve 102. An outlet 107 is also provided between the connecting pipe 104 and the abutment plate 105.

[0018] To facilitate the installation of the outer sleeve 102, the abutment plate 105 is also provided with a limiting platform 108 that matches the outer sleeve 102.

[0019] To facilitate the twisting of the connecting pipe, the limiting platform 108 is also provided with an anti-slip strip 109 for the connecting pipe 104.

[0020] In order to form a water cover inside the drain and prevent backflow of odors, the height of the drain pipe 103 is located above the outlet 107 to form a water cover.

[0021] To enhance the strength of the outer tube 102, a limiting ring 110 matching the outer tube 102 is also provided on the outer tube 102, and several reinforcing ribs 111 are provided between the limiting ring 110 and the outer tube 102.

[0022] To reduce production costs, the water outlet is usually made of stainless steel, which is more expensive, while the connecting pipe is made of plastic, which is less expensive. Therefore, increasing the height of the connecting pipe can effectively reduce production costs. The height of the connecting pipe is higher than the height of the outer sleeve 102.

[0023] To facilitate control of the fluid discharge direction, a guide elbow 112 is rotatably provided on the drain pipe 103.

[0024] To facilitate the installation of the guide elbow 112, a connecting sleeve 113 is locked onto the drain pipe 103. A first engaging ring platform 114 is provided on the connecting sleeve 113. The guide elbow 112 is provided with a second engaging ring platform 115 that engages with the first engaging ring platform 114. A second sealing ring is also provided between the guide elbow 112 and the drain pipe 103.

[0025] Both the first sealing ring 106 and the second sealing ring are rubber rings or silicone rings.

[0026] Working principle: During installation, insert the water outlet seat into the drain outlet. At this time, place the outer sleeve 102 on the abutment plate 105. By connecting the water outlet seat with the connecting pipe, the connecting pipe gradually pushes the outer sleeve 102 against the outer wall of the drain outlet and makes it abut against the outer wall, thereby completing the fixation of the outer sleeve 102 and the drain device. When in use, fluid flows from the outlet seat into the connecting pipe and out from the outlet 107, gradually overflowing the outer sleeve 102 until the water level is higher than the drain pipe 103. At this time, the fluid is discharged from the drain pipe 103, completing the drainage.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
