Technical Field

[0001] The utility model relates to the technical field of three-way joints, in particular to a quick-connect type three-way joint. Background Technique

[0002] A quick connector is a pipe joint that can be quickly disassembled and assembled without using tools. It has the advantages of compact structure, small size, light weight, high pressure resistance, interchangeability, etc. It is particularly suitable for pipelines that need to be frequently disassembled and assembled in an emergency. A three-way quick connector is a type of quick connector.

[0003] A leak-proof jointless quick-install U-shaped three-way pipe for domestic hot water with the publication number of CN218294865U has the following defects in use:

[0004] When the utility model is actually used, the stability of the connection between the extended auxiliary pipe and the U-shaped pipe can be increased by the corresponding setting state of the external thread and the internal thread, and at the same time, it can be adjusted according to the installation requirements. The overall sealing performance after the length adjustment of the extended auxiliary pipe and the U-shaped pipe can be increased by the corresponding setting state of the annular card slot, the sealing ring, the adapter card block, the limit card slot and the gasket. In the actual use process, the distance between the interface position of the three-way pipe and the pipeline to be connected is not necessarily equal. If the pipeline to be connected is fixed, the device cannot adjust the length of the connection part at any time and use it flexibly. For this reason, we propose a quick-connect type three-way joint. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a quick-connect type three-way joint, which solves the problem that the distance between the interface position of the three-way pipe and the pipeline to be connected is not necessarily equal.

A plurality of clamping grooves 5 are provided on the inner wall surface of the first connecting pipe 3. A through hole 6 is provided on the outer wall surface of the second connecting pipe 4. A clamping block 7 is sleeved inside the through hole 6. The clamping block 7 is composed of a cylindrical part, a hemispherical part at the top and a disc part at the bottom. Through the design of the through hole 6 and the clamping block 7, the clamping block 7 can be clamped in different through holes 6 to control the extending length of the second connecting pipe 4, thereby making the use of the device more flexible. When connecting pipes with different spacing distances around at a fixed position, through the spherical design at the top of the clamping block 7, on the premise of ensuring the clamping stability, the second connecting pipe 4 can be subjected to less resistance when changing the length;

[0023] A spring 8 is sleeved on the outer wall surface of the cylindrical part of the clamping block 7. A first sealing sleeve 9 is sleeved on the outer wall surface of the first connecting pipe 3. The first sealing sleeve 9 is located inside the fixing hole 2. Through the design of the first sealing sleeve 9, the interface between the fixing box 1 and the first connecting pipe 3 can be sealed to avoid air leakage and water leakage problems during the use of the device. The spring 8 is limited by the through hole 6 and the disc part of the clamping block 7. Through the design of the spring 8, the position of the clamping block 7 can be restricted so that when it moves to the next clamping groove 5, it can automatically pop out to perform clamping and limiting on the second connecting pipe 4. A first baffle 10 is sleeved inside the second connecting pipe 4. The outer wall surface of the first baffle 10 is in close contact with the inner surface of the second connecting pipe 4. A number of first filtering holes 11 are opened on one side of the first baffle 10. Through the design of the first baffle 10 and the first filtering holes 11, while ensuring the normal transportation of water, gas, etc. by the device, it can prevent some larger sundries from passing through and causing blockage of the device or the connected pipelines. A connecting rod 12 is fixedly installed on one side of the first baffle 10. The connecting rod 12 is composed of a cylindrical part and a disc part. A second baffle 13 is arranged on one side of the first baffle 10. A number of second filtering holes 14 are opened on one side of the second baffle 13.

The second baffle 13 is installed together through the connecting rod 12 and the connecting hole 15. Through the rotational design of the second baffle 13, the aligned area between the first filtering holes 11 and the second filtering holes 14 can be controlled by rotation, thereby adjusting the flux between different pipelines of the device. At the same time, by rotating the second baffle 13, one of the pipelines can be temporarily sealed, making the use of the device more flexible. A first contact groove 16 is opened on one side of the second baffle 13. A second contact groove 17 is opened on one side inside the first contact groove 16. Through the design of the first contact groove 16 and the second contact groove 17, on the one hand, it is convenient for users to directly adjust the states of the first baffle 10 and the second baffle 13 with tools outside, and on the other hand, the first baffle 10 and the second baffle 13 can be directly taken out with a tool with a hook at the front end, facilitating effective cleaning and replacement. A fixing plate 18 is fixedly installed on one side of the fixing box 1. A number of threaded holes 19 are fixedly installed on one side of the fixing plate 18. A bolt 20 is threadedly connected inside the threaded hole 19. Through the design of the threaded hole 19 and the bolt 20, the position of the device body can be fixed, facilitating the staff to adjust the pipelines to be connected and the device body at any time.
