Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the present utility model provides an embodiment of a flare fitting, comprising: the connector 1 and the cover 2 are provided with a sleeved part 12 and an installation part 11, the installation part 11 is fixedly connected with the sleeved part 12, the installation part 11 and the sleeved part 12 are integrally cast in production, and a fixing ring 3 is fixedly arranged at the joint of the installation part 11 and the sleeved part 12.

As shown in fig. 1-3, the mounting portion 11 is provided with a first internal thread 111 for mounting the connector 1 in the gauge, the telescoping portion 12 is provided with an external thread 121, and the telescoping portion 12 is provided with a sealing portion 122.

Further, as shown in fig. 1-2, the cover 2 is fixedly provided with a plurality of ribs 4, the cover 2 is provided with a second internal thread 21, the cover 2 is fixedly provided with a sealing ring 22, and the cover 2 is sleeved outside the glass tube.

Specifically, as shown in fig. 4 to 5, the sealing ring 22 is provided with a clamping part 221 and an outward expansion part 222, the sealing part 122 is matched with the clamping part 221 to seal the glass tube, the sealing ring 22 is made of silica gel material, and the silica gel has good elasticity, so that the glass tube can be sealed when the sealing part 122 is attached to the clamping part 221.
