Description

A three-way connector with filtering function

Technical Field

The utility model relates to the technical field of three-way joints, in particular to a three-way joint with a filtering function.

Background Art

Most of the installation materials for household water pipes use hoses as the inlet and outlet pipes. There is only one water pipe entering the house from the outside, and multiple joints are required to meet the needs of home use. Most of them use straight pipe tees.

The utility model patent application document with publication number "CN201803041U" discloses a three-way joint, in which a reducing pipe opening is arranged at the inlet of the water inlet pipe of the three-way joint, and reducing pipe openings are arranged at the pipe openings of the two water outlet pipes. The angle between the two water outlet pipes is less than 60°. The reducing pipe opening is arranged at the joint of the three-way joint mainly to facilitate the connection with the plastic hose, which is firm and leak-proof after connection; the angle between the two water outlet pipes is less than 60°, which can meet the requirement of inserting the same plastic pipe, saving raw materials, and no need to open extra grooves, saving labor.

The three-way joint disclosed in the above document has the following defects: the technical solution cannot filter impurities from the water source during use and has relatively low practicality.

It can be seen from this that the existing three-way joint does not have a good filtering structure, and it is necessary to improve the existing shortcomings and provide a three-way joint with a filtering function.

Utility Model Content

The purpose of the utility model is to provide a three-way connector with a filtering function to solve the problems raised in the above background technology.

In order to solve the above technical problems, the utility model is realized by the following technical solutions:

The utility model discloses a three-way joint with a filtering function, comprising a main pipe body, a fixed structure is arranged inside the main pipe body, a filtering assembly is arranged inside the fixed structure, the filtering assembly comprises a fixed plate, a cylinder, a clamping block, a spring, a movable block, a sealing plate, an outer shell, a filter plate, an activated carbon filter layer and a pull ring, a cylinder is fixedly installed on the lower surface of the fixed plate, the number of the cylinders is fixed to two, a clamping block is fixedly installed on one end of the cylinder, a spring is sleeved on the circumferential side surface of the cylinder, a movable block is movably installed on the circumferential side surface of the cylinder, the movable block is connected to the spring, a sealing plate is fixedly installed on the lower surface of the fixed plate, the inner wall of the fixed plate is fixedly installed on the outer shell, the filter plate is fixedly installed on the upper surface of the outer shell, the inner wall of the outer shell is provided with an activated carbon filter layer, and a pull ring is arranged on the upper surface of the fixed plate.

Furthermore, the fixed structure includes a mounting ring, a cavity, a slide groove and an expansion hole. The mounting ring is fixedly installed inside the main body, and a clamping block is slidably connected inside the mounting ring. The mounting ring has a cavity inside, and a slide groove is provided on the upper surface of the mounting ring, and the slide groove is connected to the cavity. The upper surface of the mounting ring has an expansion hole, and the expansion hole is connected to the slide groove and the expansion hole.

Furthermore, a groove is formed on the upper surface of the main pipe body, and a sealing gasket is movably installed inside the groove.

Furthermore, a thread groove is formed at one end of the main pipe body.

Furthermore, a shunt pipe is provided at the other end of the main pipe body, and connecting pipes are provided at both ends of the shunt pipe.

Furthermore, the circumferential side surfaces of the two connecting pipes are provided with limiting grooves, and the number of the limiting grooves is fixed at three.

The utility model has the following beneficial effects:

(1) The utility model inserts the outer shell into the inner wall of the mounting ring by fitting it to the outer shell, and then aligns the two clamping blocks with the expansion holes and inserts them into the interior of the cavity. When the clamping blocks fit the bottom of the cavity, the movable block presses against the upper surface of the mounting ring and moves upward, thereby squeezing the spring to contract. The elastic force of the spring presses the movable block tightly, and then the fixing plate is rotated to complete the installation of the filter assembly. When disassembling the filter assembly, the pull ring is pulled to rotate the clamping block to the expansion hole and then pulled upward to disassemble it. While achieving the filtering effect, the filter layer can also be disassembled and replaced. The use cost is also low, which improves practicality.

Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time.

Please refer to Figures 1 to 4. The utility model is a three-way joint with a filtering function, including a main body 1, a fixed structure 2 is provided inside the main body 1, a filter assembly 3 is provided inside the fixed structure 2, and the filter assembly 3 includes a fixed plate 301, a cylinder 302, a block 303, a spring 304, a movable block 305, a sealing plate 306, an outer shell 307, a filter plate 308, an activated carbon filter layer 309 and a pull ring 310. The lower surface of the fixed plate 301 is fixedly mounted with a cylinder 302, and the number of the cylinders 302 is fixed to two. A clamping block 303 is fixedly installed at one end of the cylinder 302, a spring 304 is sleeved on the circumferential side of the cylinder 302, a movable block 305 is movably installed on the circumferential side of the cylinder 302, and the movable block 305 is connected to the spring 304. A sealing plate 306 is fixedly installed on the lower surface of the fixed plate 301, an outer shell 307 is fixedly installed on the inner wall of the fixed plate 301, a filter plate 308 is fixedly installed on the upper surface of the outer shell 307, an activated carbon filter layer 309 is provided on the inner wall of the outer shell 307, and a pull ring 310 is provided on the upper surface of the fixed plate 301;

Put the outer shell 307 into the inner wall of the mounting ring 201, and then align the two blocks 303 with the expansion holes 204 and put them into the cavity 202. When the block 303 fits with the bottom of the cavity 202, the movable block 305 presses the upper surface of the mounting ring 201 and moves upward, thereby squeezing the spring 304 to contract. The elastic force of the spring 304 presses the movable block 305 tightly, and then the fixed plate 301 is rotated to complete the installation of the filter assembly 3.

The fixed structure 2 includes a mounting ring 201, a cavity 202, a slide groove 203 and an expansion hole 204. The mounting ring 201 is fixedly installed inside the main body 1, and a clamping block 303 is slidably connected inside the mounting ring 201. The cavity 202 is opened inside the mounting ring 201, and the slide groove 203 is opened on the upper surface of the mounting ring 201. The slide groove 203 is connected to the cavity 202. The expansion hole 204 is opened on the upper surface of the mounting ring 201, and the expansion hole 204 is connected to the slide groove 203 and the expansion hole 204.

When the block 303 fits with the bottom of the cavity 202, the movable block 305 presses the upper surface of the mounting ring 201 and moves upward, thereby squeezing the spring 304 to contract. The elastic force of the spring 304 presses and tightens the movable block 305. Then, the fixing plate 301 is rotated to complete the installation of the filter component 3. Then, the whole is installed on the external connecting piece through the threaded groove 5 tee and it can be used. When disassembling the filter component 3, pull the pull ring 310 to rotate the block 303 to the expansion hole 204 and pull it upward to disassemble it.
