[0023] 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.

[0024] Embodiment 1:

[0025] See also Figure 1-4 A connection structure of a brass joint, comprising a joint body 1, a split ring 4 is fixed in the middle of the joint body 1, a replaceable component 2 is sleeved on the outside of the joint body 1, and an extension component 3 is arranged inside the replaceable component 2;

[0026] The replaceable component 2 includes a replaceable joint 21, an external thread 22 is provided on the inner wall of the replaceable joint 21, a third sealing ring 25 is fixed to the middle of the inner part of the replaceable joint 21, a first internal thread 26 is provided on the other side of the third sealing ring 25 away from the external thread 22, a sleeve body 23 is threadedly connected to the first internal thread 26, and a first external thread 24 is provided at the position where the sleeve body 23 and the first internal thread 26 are threadedly connected;

[0027] The external thread 22 is different from the first internal thread 26 in that the first internal thread 26 is matched with the first external thread 24;

[0028] The inner diameter of the sleeve body 23 is equal to the outer diameter of the joint body 1 .

[0029] In this embodiment, the replaceable joint 21 is threadedly connected to the sleeve body 23 by threading the first internal thread 26 and the first external thread 24. After the first external thread 24 and the first internal thread 26 are threadedly connected, the first external thread 24 and the first internal thread 26 are sealed by the third sealing ring 25 fixed between the external thread 22 and the first internal thread 26. When the diameter of the pipe fitting is different, the replaceable joint 21 is replaced. The external thread 22 in the replaced replaceable joint 21 is larger than the diameter of the first internal thread 26, so that the first internal thread 26 corresponds to the first external thread 24, and the external thread 22 corresponds to the pipe fitting interface.

[0030] Embodiment 2:

[0031] See also Figure 1-4 This embodiment provides a technical solution based on the first embodiment: the extension component 3 includes a second external thread 31, the second external thread 31 is provided on the outer surface of the joint body 1, a second internal thread 32 is provided on the inner wall of the replaceable component 2, a first sealing ring 33 is fixed on the left side of the second internal thread 32, and a second sealing ring 34 is fixed on the right side of the second internal thread 32;

[0032] The second internal thread 32 matches the thread of the second external thread 31;

[0033] The first sealing ring 33 and the second sealing ring 34 are both made of rubber material, and the first sealing ring 33 and the second sealing ring 34 are tightly fitted to the outer surface of the joint body 1 .

[0034] In this embodiment, the replaceable component 2 is fixed to the outer wall of the connector body 1 by threaded connection between the second outer thread 31 and the second inner thread 32. When the brass connector needs to be changed according to the distance of the pipe diameter, the replaceable component 2 is threaded out from the second outer thread 31 to the outer side of the connector body 1 by a suitable length so that the brass connector can be connected to the pipe diameter. When the replaceable component 2 is threaded out, the sealing performance of the replaceable component 2 will decrease. The first sealing ring 33 and the second sealing ring 34 can seal the gap between the replaceable component 2 and the connector body 1 when the replaceable component 2 is turned out.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] During operation, first, according to the distance between the pipes, the replaceable component 2 is threadedly connected to the second external threads 31 opened on the outer surfaces of the two ends of the joint body 1 through the second internal threads 32, and the replaceable component 2 is extended to the appropriate positions on both sides of the joint body 1 according to the appropriate distance, and the extended joint is sealed by the first sealing ring 33 and the second sealing ring 34. If the diameter of the pipe is large and the diameter of the replaceable component 2 does not match the pipe, the replaceable joint 21 is threaded out from one end of the sleeve body 23 through the first internal threads 26 and the first external threads 24, and the replaceable joint 21 is sealed. For replacement, a replaceable joint 21 of matching diameter is installed and fixed through the first internal thread 26 and the first external thread 24, and is connected to the pipe fitting through the external thread 22 provided in the replaceable joint 21. The threaded connection between the replaceable joint 21 and the sleeve body 23 is sealed by the third sealing ring 25, so that when the joint body 1 is docked with the pipe fitting, the joint body 1 is in a completely sealed state. When the diameter of the pipe fitting matches that of the joint body 1, the replaceable component 2 is threadedly connected with the second internal thread 32 and the second external thread 31 and is removed from both ends of the joint body 1, so that the joint body 1 can be directly connected to the pipe fitting.
