DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 A conveniently connected energy-saving copper-plated pipe fitting comprises a pipe 1, a ring-shaped slot 2 is provided on one side of the pipe 1, one side of the surface of the pipe 1 is in a groove-less arrangement, a blocking ring 3 which can move laterally is provided on one side of the pipe 1, and the blocking ring 3 is adapted to the ring-shaped slot 2.

[0020] See also Figure 1-4 An annular fixed shell 4 is fixedly connected in the notch, a driving ring 5 capable of transverse movement is arranged on one side of the annular fixed shell 4 , and the blocking ring 3 is fixedly connected to the driving ring 5 .

[0021] See also Figure 1-4 A slider 6 is provided in the annular fixed shell 4, one side of the slider 6 is fixedly connected to a connecting rod 7, one end of the connecting rod 7 away from the slider 6 is fixedly connected to the driving ring 5, and one side of the slider 6 is fixedly connected to a push block 16, which is provided to facilitate the staff to push the slider 6.

[0022] See also Figure 1-4 A sealing ring 1 8 is fixedly connected to the inner wall of the blocking ring 3, and a sealing ring 2 9 is fixedly connected to the inner wall of the driving ring 5. The sealing ring 1 8 and the sealing ring 2 9 are both made of rubber. The inner wall of the sealing ring 1 8 is inclined, and one side of the inner wall of the annular slot 2 is also inclined. This arrangement is to ensure that the sealing ring 1 8 has good sealing performance when it is squeezed into the annular slot 2. A locking plate 17 is arranged in the groove on one side of the blocking ring 3, and a locking block 18 is fixedly connected to one side of the locking plate 17. A spring 2 19 is fixedly connected to the other side of the locking plate 17. One end of the spring 2 19 away from the locking plate 17 is fixedly connected to the blocking ring 3. The locking block 18 arranged on one pipe 1 is movably plugged into another pipe 1. Figure 1 It is a cross-sectional view of two pipes 1 being snap-fitted and assembled.

[0023] See also Figure 1-4 A limit ring 10 is fixedly connected to the inner wall of the annular fixed shell 4, and a plurality of positioning grooves 11 are opened on the limit ring 10. A clamping plate 12 is slidably connected in the groove on one side of the slider 6, and a clamping block 13 is fixedly connected to the bottom of the clamping plate 12, and the clamping block 13 is movably inserted in the corresponding positioning groove 11.

[0024] See also Figure 1-4 A track 14 is fixedly connected in the groove on one side of the slider 6, and the clamping plate 12 is slidably connected to the surface of the track 14. The surface of the track 14 is sleeved with a spring 15, a blocking ring 3, an annular fixed shell 4, a driving ring 5, a slider 6, a connecting rod 7, a sealing ring 1 8, a sealing ring 2 9, a limiting ring 10, a positioning groove 11, a clamping plate 12, a clamping block 13, a track 14, a spring 15, a push block 16, a locking plate 17, a locking block 18 and a spring 2 19 cooperate to form a clamping mechanism. The docking method of the technical solution thus arranged also helps to alleviate the problem of installation accuracy. There can be a certain distance between the two pipes, and they can still be well docked. However, for existing pipes, two pipes need to be seamlessly docked, and then subsequent welding or other connection treatments are performed, which is inconvenient to use.

[0025] When in use, the two pipes are butted together so that the sealing ring 3 on one pipe is inserted into the annular slot 2 on the other pipe. The slider 6 is pushed hard by the push block 16. The slider 6 will drive the driving ring 5 to move through the connecting rod 7, and the driving ring 5 will drive the sealing ring 3 to move tightly, so that the inner wall of the sealing ring 8 will be squeezed and the sealing effect will be improved. At this time, the clamping block 13 is just aligned with the positioning groove 11, and then the clamping block 13 will be inserted into the positioning groove 11, and then each pipe is fixed by using structures such as clamps and mounting seats, so that the pipes are butted together. The setting of the locking plate 17, the locking block 18 and the spring 19 plays the role of locking. The two pipes can be locked. When the two pipes need to be separated, the locking plate 17 is pressed, the spring 19 is compressed, and the locking plate 17 drives the locking block 18 to move. In this way, the two pipes are unlocked first, but since they are fixed separately, the blocking ring 3 set on one pipe is inserted into the annular slot 2 set on the other pipe. The staff moves the card plate 12, the spring 15 is compressed, and the card plate 12 drives the card block 13 to disengage from the positioning groove 11. Then the slider 6 can be pulled by the push block 16, and the slider 6 will drive the drive ring 5 to move through the connecting rod 7, and the drive ring 5 will drive the blocking ring 3 to disengage from the annular slot 2.
