The utility model will be further described in detail below in conjunction with the accompanying drawings.

Embodiment 1: This embodiment discloses a capillary joint. Referring to Figures 1 and 2, it includes a joint body 1, a pagoda joint 2 that is detachably connected to the joint body 1, and a capillary joint used for connection between the pagoda joint 2 and the joint body 1. The connection device 4, the pagoda joint 2 is connected to the capillary tube 3, one end of the pagoda joint 2 is sleeved with the joint body 1, and a sealing ring is provided at the end of the pagoda joint 2. The number of the specific sealing rings is set according to the actual situation. In this embodiment There are two sealing rings in it for sealing the connection between the pagoda connector 2 and the connector body 1. The other end of the pagoda connector 2 is sleeved with the capillary tube 3. There is a limiter on the outer wall of the pagoda connector 2 that offsets the connector body 1. The limit block 5 is used to limit the connection between the pagoda joint 2 and the joint body 1. The limit block 5 is annular and is integrally formed with the pagoda joint 2.

Referring to FIG. 2 , the connecting device 4 includes a connecting sleeve 41 that is detachably connected to the connector body 1 , a clamping portion disposed inside the connecting sleeve 41 that can resist the limiting block 5 , and a clamping portion disposed inside the connecting sleeve 41 for the capillary tube 3 The pressing part that is pressed tightly with the pagoda joint 2. The connecting sleeve 41 and the joint body 1 can be connected by threads but are not limited to them. The clamping part offsets the limiting block 5 and is mainly used for limiting the connecting sleeve 41. The clamping part includes a stepped block provided on the inner wall of the connecting sleeve 41. 6. The pressing part includes an annular pressing block 7 arranged on the inner wall of the connecting sleeve 41 .

Working principle: Pass the capillary tube 3 through the connecting sleeve 41, then sleeve the end on the pagoda connector 2, and then insert one end of the pagoda connector 2 into the interface of the connector body 1 until the interface between the limit block 5 and the connector body 1 offset each other, and then move the connecting sleeve 41 upward, and thread the connecting sleeve 41 with the joint of the joint body 1, and rotate the connecting sleeve 41 until the step block 6 and the limit block 5 offset to realize the connection between the capillary tube 3 and the joint body 1. When the annular pressure block 7 keeps squeezing the wall of the capillary tube 3, the connection between the capillary tube 3 and the pagoda connector 2 is closer. In this embodiment, there are three interfaces on the connector body 1, corresponding to the number of pagoda connectors 2. For three, three capillary tubes 3 can be connected. The installation of the capillary tube 3 is not limited by space, and there is no need to install the capillary tube 3 in a narrow space, making disassembly and assembly more convenient; at the same time, the connector body 1 can be used as a standard part, and there is no inappropriate size of the pagoda connector 2 question.

Embodiment 2: Referring to Figures 3 and 4, this embodiment discloses a capillary tube joint. The main difference from the capillary tube 3 joint in Embodiment 1 is that an inner chamfer surface 8 is provided at one end of the connecting sleeve 41 away from the joint body. Under the action of the inner chamfered surface 8, the capillary tube 3 passes through the connecting sleeve 41 more smoothly.

Embodiment 3: Referring to Figures 5-7, this embodiment discloses a capillary joint. The main difference from the capillary 3 joint in Embodiment 1 is that the structure of the connecting device 4 is different. In this embodiment, the clamping part includes a connecting device. The elastic compression ring 9 inside the sleeve 41 is provided with a break 91. One end of the elastic compression ring 9 offsets the connecting sleeve 41, and the other end forms a clamping portion to offset the limiting block 5. The elastic compression ring 9 is 9 The inner wall forms a pressing part; during the connection process of the capillary tube 3, it is necessary to first pass the capillary tube 3 through the connecting sleeve 41 and the elastic compression ring 9. During the rotation of the connecting rod, the elastic compression ring 9 and the limit block 5 are offset. , at this time, one end of the elastic compression ring 9 is against the limit, and the other end is against the connecting sleeve 41. Therefore, when the connecting sleeve 41 continues to be rotated, the elastic compression ring 9 will shrink under the pressure (the gap at the fracture 91 is reduced) , squeeze the capillary tube 3 so that the capillary tube 3 and the pagoda joint 2 are connected more closely.
