Description

一种电子膨胀阀丝套螺母与磁芯的联接结构
【技术领域】
本实用新型涉及变频空调用的电子膨胀阀，尤其涉及一种电子膨胀阀丝套螺母与磁芯的联接结构。 
【背景技术】
电子膨胀阀是空调等系统上常用的控制元件，现有的丝套螺母与磁芯的螺纹配合，时日过久，螺纹磨损、振动或者是高压情况下，丝套螺母与磁芯部件容易松动。 
【实用新型内容】
本实用新型为了解决现有技术的上述不足，提供了一种电子膨胀阀丝套螺母与磁芯的联接结构。 
本实用新型的上述目的通过以下的技术方案来实现：一种电子膨胀阀丝套螺母与磁芯的联接结构，包括丝套螺母和磁芯，其特征在于：所述丝套螺母设有槽。 
所述槽的横截面为凹型。 
所述槽的横截面可以是V形、U形，也可以是梯形等形状。 
本实用新型与现有技术相比的优点是：由于采用以上技术方 案，本实用新型的电子膨胀阀丝套螺母与磁芯结构的联接结构，槽可限制丝套的相对上下自由度，螺纹可以限制丝套螺母与阀芯的相对转动，其特点主要是结构简单、丝套加工方便，可以由车床一次装夹加工。 
【附图说明】
图1为本实用新型电子膨胀阀丝套螺母结构示意图； 
图2为本实用新型电子膨胀阀丝套螺母与阀芯的联接结构示意图。 
附图中，1-丝套螺母；2-磁芯；3-槽。 
【具体实施方式】
下面结合附图对本实用新型进一步详述： 
如图1、图2所示，一种电子膨胀阀丝套螺母与磁芯的联接结构，包括丝套螺母1和磁芯2，其特征在于：所述丝套螺母1设有槽3，所述槽3的横截面为凹型，可以是V形、U形，也可以是梯形等形状，图中示例槽3的形状为V形。 
实施时，丝套螺母1置于磁芯2中，通过丝套螺母1与磁芯2注塑一体成型，为防止丝套螺母1在注塑体中相对运动松动，在磁芯2外加工有外螺纹和槽3，防止相对的转动与上下运动。 
但是，上述的具体实施方式只是示例性的，是为了更好的使本领域技术人员能够理解本专利，不能理解为是对本专利包括范 围的限制；只要是根据本专利所揭示精神的所作的任何等同变更或修饰，均落入本专利包括的范围。
