Abstract
The utility model discloses a stop rod pivoting structure for an electronic expansion valve. The stop rod pivoting structure comprises a stop rod and a screw sleeve, and is characterized in that: the stop rod comprises a rod body and a base, and is L-shaped; the base is provided with a through hole in which an inwardly-concave incision is formed; and the screw sleeve is provided with a boss. Compared with the prior art, the stop rod pivoting structure has the advantages: the stop rod is connected with the screw sleeve of a rotor component in a riveting connection way, so that the influence of a welding way on a product is avoided, and the process is relatively simple and convenient. The inwardly-concave incision on the base of the stop rod is matched with the boss of the screw sleeve, so that rotation and loosening between the stop rod and the screw sleeve are prevented effectively.
Description
[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 stop rod riveting assembling structure that is used for electric expansion valve.
[background technique]
The retainer of electric expansion valve generally adopts welding manner to connect with rotor part at present; And rotor part generally is injected with magnetic material; Damage magnetic material during welding easily, technology is comparatively complicated, and soldering point can produce the phenomenon of getting rusty under the long-term corrosion of fluid (refrigerant); Novel stop rod riveting assembling structure cancellation welding procedure; Overcome existing stop rod and adopt the existing above-mentioned defective of welding, and a kind of riveting connecting mode of being convenient to assemble is provided, can reach the effect that stop rod is not loosening, do not rotate.
[model utility content]
The utility model provides a kind of stop rod riveting assembling structure that is used for electric expansion valve in order to solve the above-mentioned deficiency of existing technology.
The above-mentioned purpose of the utility model realizes through following technological scheme: a kind of stop rod riveting assembling structure that is used for electric expansion valve, comprise stop rod and silk braid, and it is characterized in that: said stop rod comprises the body of rod and base, is the L type; Said base is provided with through hole, and the inboard facade of through hole is provided with the indent otch, and said silk braid is provided with boss.
Said indent otch can be different shapes such as square, circular, fan-shaped, triangle.
Said indent otch is at least one.
Said silk braid boss exceeds stop rod base 1.0-4.0mm.
The utility model advantage compared with prior art is: the utility model characteristics adopt the connecting mode of riveting that stop rod is connected with the silk braid of rotor part, have avoided the influence of welding manner to product, and technology is simple and convenient relatively.The indent otch of stop rod base and the cooperation of silk braid boss have effectively prevented rotation between stop rod and the silk braid and loosening.

[embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
To shown in Figure 4, a kind of stop rod riveting assembling structure that is used for electric expansion valve comprises stop rod 1 and silk braid 2, it is characterized in that: said stop rod 1 comprises the body of rod 11 and base 12, is the L type like Fig. 1; Said base 12 is provided with through hole 121, and through hole 121 inboard facades are provided with indent otch 122, and said silk braid 2 is provided with boss 21.
As shown in Figure 2, said indent otch 122 can be different shapes such as square, semicircle, fan-shaped, triangle, and the indent otch 122 that present embodiment provides is semicircular, and quantity is four.
As shown in Figure 4, said silk braid boss 21 exceeds stop rod base 12 parts, and the height of this part is 1.0-4.0mm.
The utility model practical implementation process is following: electric expansion valve stop rod 1 is one-body molded through die stamping with sheet material, and sheet metal thickness is generally at 0.7mm-1.2mm, shape such as Fig. 1, shown in Figure 2.The rotor part silk braid 2 of electric expansion valve; Be injected with magnetic substance; Rotation needs scope and limits; So electric expansion valve generally has stopping device, adopt stop rod 1 and electric expansion valve stopper 3 to constitute stopping device (as shown in Figure 5) here, stop rod 1 connects (as shown in Figure 4) with rotor part silk braid 2;
Like Fig. 2, shown in Figure 4; Through the riveting mode; Pressure head frock head is the small outstanding plum blossom shape corresponding with base indent otch 122 shapes of stop rod 1, when pressure head is stamped into the center hole 211 of silk braid boss 21 of rotor part in the riveting process, because the pressure head profile of frock is corresponding with the indent otch 122 of stop rod 1 base plate through holes 121; Make the cylindrical distortion of boss 21 and be pressed against 122 li at the indent otch of stop rod base plate through holes 121; No longer be cylindrical, form engagement, effectively prevented the rotation of stop rod.Simultaneously, because through punching press, silk braid boss 21 exceeds the part of stop rod base 12 by expanding distortion, pushes down stop rod, has prevented the loosening of stop rod.
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 done anyly be equal to change or modify, all fall into the scope that this patent comprises.
