Abstract

The utility model discloses an axial lower positioning structure of an electronic expansion valve coil. The axial lower positioning structure is characterized by comprising a positioning clamp spring, a valve seat flange and a coil case. The coil case comprises an upper case and a lower case, the lower case is provided with a positioning clamp spring groove, and the positioning clamp spring is inserted into the positioning clamp spring groove, extends out of the lower case and clamps an air inlet elbow of the electronic expansion valve. The valve seat flange is provided with a convex portion. Compared with the prior art, the axial lower positioning structure has the advantages that the positioning clamp spring groove is arranged in the lower case of the coil case, and a welding process is eliminated. In addition, the axial lower positioning structure has the advantages of being energy-saving, environment-friendly, simple in structure and reasonable in design, and the coil is fixed firmly.

Description

A kind of axially lower position structure of coil of electronic expansion valve
[technical field]
The utility model relates to the electric expansion valve that frequency converting air conditioner is used, and relates in particular to a kind of axially lower position structure of coil of electronic expansion valve.
[background technique]
In the prior art, the linkage structure of electronic expansion valve body and coil mainly is to be with flexible card in lower housing welding one, in valve seat welding one positioning disk with locating slot, this kind structural manufacturing process complexity, the casing weld easily gets rusty, thereby affects stability and the valve reliability of operation of motor.
[model utility content]
The utility model provides a kind of axially lower position structure of coil of electronic expansion valve in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of axially lower position structure of coil of electronic expansion valve, it is characterized in that: comprise location jump ring, valve seat flange and coil casing, described coil casing comprises upper casing and lower housing, lower housing is provided with the location jump-ring slot, the location jump ring inserts in the jump-ring slot of location and stretches out lower housing, clamps the intake elbow of electric expansion valve; Described valve seat flange is provided with male part.
Described location jump ring comprises epimere and hypomere, and the front is Ω shape, and the side is inverted L-shaped.
The utility model advantage compared with prior art is: the jump ring locating slot on the lower housing of coil casing, saved welding procedure, and energy-conserving and environment-protective, and the utility model is simple in structure, and reasonable in design, the coil fixation.
[ Description of drawings]
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of the lower housing of coil casing;
Fig. 3 is the structural representation of location jump ring.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of axially lower position structure of coil of electronic expansion valve, it is characterized in that: comprise location jump ring 1, valve seat flange 2 and coil casing 3, described coil casing 3 comprises upper casing 31 and lower housing 32, lower housing 32 is provided with location jump-ring slot 4, described location jump ring 1 comprises epimere 11 and hypomere 12, the front is Ω shape, the side is inverted L-shaped, the hypomere 12 of location jump ring 1 inserts in the location jump-ring slot 4 and stretches out lower housing 32, epimere 11 is stuck on the lower housing 32, clamps the intake elbow 5 of electric expansion valve; Described valve seat flange 2 is provided with male part 21, supports coil casing 3.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
