Description

Technical Field

[0001] The invention belongs to the technical field of pipeline connection, and in particular is a multi-channel water inlet interface structure for a pump. Background Art

[0002] A water pump is a mechanical device for conveying liquid or pressurizing liquid, and its water inlet is provided with a corresponding interface to connect with the external pipe. The existing multi-channel water inlet interface of the water pump is designed with multiple channels, so that multiple external pipes can be smoothly connected to the water pump, and the liquid can be introduced and multiple liquids can be mixed. The pagoda interface at its connection end is usually fixed in design, which can only meet the clamping installation of hoses of the same diameter. When it is necessary to install and connect pipes of other sizes, it is necessary to replace other interfaces with matching diameters, which greatly reduces the scope of use of a single interface, so it needs to be improved.

Subsequently, when the second pagoda ring, the second connecting frame and the second push column move toward each other, the gas in the second air cavity can be compressed to push the second spring to move toward each other. Finally, the gas can enter the second air cylinder through the second connecting pipe to push the second piston rod and the second switching interface to contract alone, so that the pipeline can switch the diameter more smoothly.

[0035] The present invention sets a first fixing component and a second fixing component. When the pipeline is installed on the two end surfaces of the three-way pipeline interface, the first pagoda ring is engaged to drive it and the first connecting frame, the positioning ring and the first magnetic ring to move toward each other as a whole, until the first magnetic ring and the second magnetic ring are fit and fixed. At that time, the pipeline is installed on the outer end surface of the first pagoda ring and the second pagoda ring is engaged to push it and the second connecting frame and the first magnetic block to move toward each other as a whole. Subsequently, the first magnetic block and the second magnetic block can be fit and fixed.

[0074] The above scheme is adopted: by providing a second piston rod 8012, through the second connecting frame 8023 and the second push column 8022 moving toward each other, the gas on the inner wall of the second air chamber 8021 can be compressed to push the second spring 8032 to move toward each other, so that the gas can smoothly flow through the second connecting pipe 8033 to the inner wall of the second gas cylinder 8011 to push the second piston rod 8012 and the second switching interface 504 to contract.

[0081] like Figure 1 and Figure 2 As shown, there are two auxiliary handles 3 , and the two auxiliary handles 3 have the same size.

[0082] By adopting the above solution, the auxiliary handles 3 are provided, and the operator can grasp the two auxiliary handles 3 by hand to drive the bottom of the mounting end 1 to rotate and be spirally mounted and connected with the water inlet of the water pump.

[0083] The working principle and use process of the present invention:

[0084] First, the operator can rotate the installation end 1 to correspond to the water inlet of the water pump, and can fit and press the bottom of the three-way pipe interface 2 against the auxiliary handle 3. Then, when the pipe needs to be installed, the pipes with different inner diameters can be fit into the three-way pipe interface 2, the first switching interface 502 and the second switching interface 504 for adaptation and switching installation, thereby increasing the scope of use.

[0085] When installed at the three-way pipe interface 2, the inner wall of the pipe can be fitted with the first pagoda ring 501 to push the two to move toward each other with the first connecting frame 7023 and the first push column 7022, so that the gas pushes the first spring 7032 to move toward each other, and then flows to the first gas cylinder 7011 and the inner wall of the connecting pipe 901, and the gas will push the first air cavity 7021 and the first switching interface 502 to shrink, and the gas on the inner wall of the connecting pipe 901 will push the third valve column 903 to move away from each other and flow into the inner wall of the second gas cylinder 8011 to drive the second piston rod 8012 and the second switching interface 504 to shrink synchronously, until the first magnetic ring 7042 and the second magnetic ring 7043 are fitted and fixed by magnetic attraction, and the pipe is successfully installed at the outer end of the three-way pipe interface 2.

[0086] When it is necessary to install it at the first switching interface 502, the second pagoda ring 503 can be engaged and pushed to move the second connecting frame 8023 and the second push column 8022 toward each other, so that the gas inside the second air chamber 8021 can be compressed to push the second spring 8032 to move toward each other, and then flow to the inside of the second air cylinder 8011 through the second connecting pipe 8033. At this time, the second piston rod 8012 and the second switching interface 504 can be pushed alone to contract, so that the pipeline can be successfully installed at the outer end of the first switching interface 502.

[0087] Finally, when it is necessary to install at the second switching interface 504 , the surface of the third pagoda ring 505 is directly engaged and the inner end is fitted and fixed to the outer end of the first switching interface 502 to achieve installation at the second switching interface 504 .

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
