[0002] Pipe fittings are a collective term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, sealing, and support.

[0003] Existing technologies often employ a novel pipe fitting disclosed in CN203703412U. This technology includes a pipe body, a small pipe fitting mounted on the pipe body, a large pipe fitting mounted on the pipe body, and a filter body installed within the pipe body. The small pipe fitting is connected to the large pipe fitting, the filter body is installed near the large pipe fitting, a sealing ring is provided near the small pipe fitting, a frosted layer is provided on the inner wall of the small pipe fitting, and a wear-resistant layer is provided on the outer surface of the pipe body. This technology has a simple structure, is convenient to use and install, easy to operate, has a good sealing effect, a tight connection, a wide range of applications, a long service life, and a safe and reliable function. However, the above technology still has problems in use due to structural limitations.

[0004] When installing the filter body, the above technology lacks a locking component. Since the filter body needs to be fixedly connected to the pipe, external tools are used to weld the filter body and the pipe, which is a non-removable connection method. This installation process is not only time-consuming and labor-intensive, but also makes it impossible to completely disassemble the filter body afterwards. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of the lack of locking components in the filter body in the prior art, and to propose an internal filter type pipe fitting.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An internal filter type pipe fitting includes a pipe fitting body, on which the following are provided:

[0008] The mounting base, the flow chamber, and the filter mesh are provided. The mounting base is disposed in the main body of the pipe fitting. The flow chamber is opened in the mounting base. Two sets of filter mesh are respectively opened at the left and right ends of the mounting base, and both sets of filter mesh are connected to the flow chamber.

[0009] A fixed circular groove and two movable circular arc blocks are provided. The fixed circular groove is located inside the main body of the pipe fitting, and the two movable circular arc blocks are respectively located at the upper and lower ends of the mounting base plate, and the two movable circular arc blocks are movably disposed in the fixed circular groove.

[0010] A locking mechanism is provided on the mounting base and is used to lock two movable arc blocks located in a fixed circular groove.

[0011] Preferably, the mounting base has discharge holes at both ends, and the discharge holes are used to discharge water and impurities in the flow chamber, and a movable plug is movably installed in the discharge hole.

[0012] Preferably, the mounting base is a cylindrical structure, the fixed circular groove is located at the middle of the pipe body, and the two movable arc blocks are both semi-circular block structures.

[0013] Preferably, the locking mechanism includes:

[0014] The mounting base is provided with a circular arc groove, a first sliding groove, and a second sliding groove. The two circular arc grooves are respectively opened at the upper and lower ends of the mounting base. The two movable circular arc blocks are respectively slidably disposed in the two circular arc grooves. The two first sliding grooves are respectively opened at the upper and lower ends of the mounting base. The two second sliding grooves are respectively opened at the upper and lower ends of the mounting base. An adjacent first sliding groove and a second sliding groove are connected to a circular arc groove.

[0015] Preferably, the locking mechanism further includes:

[0016] The movable rod, the rotating rod, and the locking threaded hole are respectively fixedly connected to two movable arc blocks, and the two movable rods extend to the outside of the mounting base through two first sliding grooves. The two rotating rods are respectively pin-connected to the extension ends of the two movable rods.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 An internal filtration pipe fitting includes a pipe fitting body 1. The left and right ends of the pipe fitting body 1 can be threaded to facilitate threaded connection between the pipe fitting body 1 and other pipe fittings. The pipe fitting body 1 is provided with a mounting base 2, a flow chamber 3 and filter mesh 4. The mounting base 2 is disposed in the pipe fitting body 1, the flow chamber 3 is opened in the mounting base 2, and two sets of filter mesh 4 are respectively opened at the left and right ends of the mounting base 2. The water in the pipe fitting body 1 is filtered twice through the two sets of filter mesh 4. At the same time, since both sets of filter mesh 4 are connected to the flow chamber 3, the water in the pipe fitting body 1 enters the flow chamber 3 from one set of filter mesh 4 on one side and then exits from the other set of filter mesh 4 on the other side.

[0028] The pipe fitting body 1 is also provided with a fixed circular groove 5 and two movable arc blocks 6. The fixed circular groove 5 is opened on the inner side of the pipe fitting body 1. The two movable arc blocks 6 are respectively set at the upper and lower ends of the mounting base 2. When the two movable arc blocks 6 are movably set in the fixed circular groove 5, the pipe fitting body 1 is connected to the mounting base 2. A locking mechanism is set on the mounting base 2 and is used to lock the two movable arc blocks 6 located in the fixed circular groove 5 so that the mounting base 2 is fixedly connected to the pipe fitting body 1.

[0029] Preferably, after the mounting base 2 is disassembled, the two sets of filter screens 4 can be directly rinsed with water. At this time, excess water and impurities remain in the flow chamber 3. Since the mounting base 2 has discharge holes 7 at both ends, and movable plugs 8 are installed in the discharge holes 7, the movable plugs 8 can be removed to discharge the water and impurities in the flow chamber 3. The mounting base 2 has a cylindrical structure, the fixed circular groove 5 is located at the middle of the pipe body 1, and the two movable arc blocks 6 are both semi-circular block structures.

[0030] The locking mechanism includes a circular arc groove 9, a first slide groove 10, and a second slide groove 11, as shown in the attached figure. Figure 3 and attached Figure 4 As shown, two placement arc grooves 9 are respectively opened at the upper and lower ends of the mounting base 2, and two movable arc blocks 6 are respectively slidably disposed in the two placement arc grooves 9. When the two movable arc blocks 6 are completely located in the two placement arc grooves 9, the placement arc grooves 9 are used to store the movable arc blocks 6. Two first sliding grooves 10 are respectively opened at the upper and lower ends of the mounting base 2, and two second sliding grooves 11 are respectively opened at the upper and lower ends of the mounting base 2. An adjacent first sliding groove 10 and a second sliding groove 11 are connected to a placement arc groove 9.

[0031] Preferably, the locking mechanism further includes a movable long rod 12, a rotating long rod 13, and a locking threaded hole 14. The two movable long rods 12 are respectively fixedly connected to the two movable arc blocks 6, and the two movable long rods 12 extend to the outside of the mounting base 2 through the two first sliding grooves 10. The two rotating long rods 13 are respectively pin-connected to the extended ends of the two movable long rods 12. A set of locking threaded holes 14 are formed in the inner wall of one rotating long rod 13, one movable arc block 6, and one placement arc groove 9. (See attached...) Figure 4 As shown, a first slide groove 10 is connected to an adjacent second slide groove 11 in an L-shape. When the movable arc block 6 is located in the fixed circular groove 5, the moving long rod 12 is located on the side of the first slide groove 10 close to the second slide groove 11, and the rotating long rod 13 is moved into the second slide groove 11 to initially lock the movable arc block 6. Then, the bolt is screwed into an adjacent rotating long rod 13, a movable arc block 6 and a locking threaded hole 14 placed on the inner wall of the arc groove 9 to lock the movable arc block 6 a second time.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] When the mounting base 2 needs to be installed, first place the mounting base 2 into the pipe body 1, and then move the two movable arc blocks 6 outwards to the placement arc groove 9 by the two moving long rods 12, so that the two movable arc blocks 6 enter the fixed arc groove 5. At this time, the moving long rod 12 is located on the side of the first slide groove 10 near the second slide groove 11, and the rotating long rod 13 is turned to place the rotating long rod 13 in the second slide groove 11 to initially lock the two movable arc blocks 6. Finally, screw the bolt into a set of locking threaded holes 14 to fix one rotating long rod 13, one movable arc block 6 and the inner wall of the placement arc groove 9, thereby locking the two movable arc blocks 6 a second time.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
