Abstract
The utility model discloses a capillary tube capable of being easily assembled. The capillary tube capable of being easily assembled comprises a body. Drop prevention steps are arranged on the outer surface of the end opening portion of the body. Preferably, the drop prevention steps are in a reverse tooth structure. A thickening layer is arranged on the end opening portion of the body. The drop prevention steps are arranged on the outer surface of the thickening layer. The capillary tube capable of being easily assembled has the advantages of being simple in assembly and high in success rate of the assembly.
Description
Technical field
The present invention relates to the air supply rate technical field, especially relate to a kind of easy assembling type capillary.
Background technology
Capillary is the vitals of air-conditioner throttling step-down.This capillary can adopt diameter to be no more than the copper pipe preparation of 6mm, also can be the other materials preparation.Their common feature is wall thin (generally being no more than 0.9mm), when carrying out connection capillaceous or capillary being connected to the miscellaneous part of air-conditioning, how to be undertaken by the modes of welding.Because capillary is thin and wall is thin, thereby in the process of welding, be easy to cause port capillaceous to be burned, increased material cost and the preparation cost of air-conditioning.For this reason, the inventor preferably resolves the problem that port is easy to burn out by the mode that the wall thickness with port part capillaceous increases.But, in when welding, be easy to port part occur owing to weld the defective of stopping up, thus assemble loaded down with trivial details, success rate is lower.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of easy assembling type capillary, and it is simple that it has assembling, and the higher characteristics of assembly yield.
To achieve these goals, the technical solution adopted in the present invention is: the easy assembling type capillary, comprise body, and the port part outer surface of described body is provided with the anticreep step.
Described anticreep step is the pawl shape.
The port part of described body is provided with thickening layer, and the anticreep step is positioned at the outer surface of this thickening layer.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: assembling is simple, and assembly yield is higher.Easy assembling type of the present invention port part capillaceous is provided with the anticreep step.Like this, only need in the port part inboard of connected capillary or miscellaneous part corresponding anticreep groove to be set, and this anticreep groove and anticreep step cooperate, when then assembling, can by with between the capillary or capillary dock to form with other attaching parts and be connected.Because such docking mode has been avoided the situation of capillary welding, thereby the obstruction of Capillary oral area can not appear, so simple to operate, success rate is higher.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks half sectional view.
Among the figure: 10, body, 11, thickening layer, 12, the anticreep step.
The specific embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as shown in Figure 1: the easy assembling type capillary, comprise the body 10 that is cast, the port part outer surface of body 10 is provided with anticreep step 12.Certainly, anticreep step 12 can be multi-turn.Like this, the connected mode that must weld in the time of can avoiding assembling, thus assembling is simple, success rate is higher.
Optimize, anticreep step 12 is the pawl shape.So-called pawl shape, the cross section that refers to anticreep step 12 can be that vertical edges is at the right angled triangle of body 10 inboards.Like this, be beneficial to smooth assembling, and after assembling finishes, be difficult between the capillary that links together or between capillary and the miscellaneous part throwing off.
Further, the port part of body 10 is provided with thickening layer 11, and anticreep step 12 is positioned at the outer surface of this thickening layer 11.Like this, be beneficial to the preparation of anticreep step 12, and capillary caves inward can avoid connecting the time.
Claims (3)
