Embodiment Construction

[0011] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0012] Examples, see figure 1 As shown: an easy-to-install capillary tube, including a tubular body 10 , and an anti-falling step 12 is provided on the outer surface of the port portion of the body 10 . Of course, the anti-off step 12 can be multi-turn. In this way, it is possible to avoid the necessary welding connection during assembly, so that the assembly is simple and the success rate is high.

[0013] Optimally, the anti-off step 12 is in the shape of inverted teeth. The so-called inverted tooth shape means that the cross section of the anti-escape step 12 can be a right triangle with the vertical side inside the body 10 . In this way, smooth assembly is beneficial, and after the assembly is completed, it is not easy to disengage between the capillary tubes connected together or between the capillary tub...

Abstract

The invention discloses an easily assembled capillary tube, which comprises a body, wherein an anti-detachment step is arranged on the external surface of a port part of the body. Preferably, the anti-detachment step is in the shape of a reverse tooth; and the port part of the body is provided with a thickened layer, and the anti-detachment step is located on the external surface of the thickened layer. The easy assembly capillary tube provided by the invention has the advantages that assembly is easy and assembly success rate is high.

Description

technical field [0001] The invention relates to the technical field of air-conditioning components, in particular to an easy-to-install capillary. Background technique [0002] Capillary is an important part of air conditioning regulation and pressure reduction. The capillary can be made of a copper tube with a diameter not exceeding 6mm, or it can be made of other materials. Their common feature is that the wall is thin (generally no more than 0.9mm), and when connecting the capillary or connecting the capillary to other parts of the air conditioner, it is mostly done by welding. Since the capillary is thin and its wall is thin, the end of the capillary is likely to be burned out during the welding process, which increases the material cost and manufacturing cost of the air conditioner. For this reason, the inventors have better solved the problem that the port is easy to burn out by increasing the wall thickness of the port portion of the capillary. However, during weld...
