Technical field
The utility model relates to a kind of nut, relates in particular to a kind of fixing spot welding nut of using of the fixing air condition compressor of compressor part that is used for.
Background technique
Air conditioner is in transportation process, because various jolting can cause the vibration that is installed in the compressor in the aircondition, thereby influence the soundness that compressor is connected with pipe arrangement, therefore need between compressor and aircondition, load onto fixing device, to solve the vibration problem of air condition compressor in transportation process, what prevent to be connected between compressor and its accessory is loosening, this shows, has increased the parts of fixing device.
In order to address the above problem, the prior art air condition compressor adds solder joint weldering nut on the upper shell cover of compressor, and the fixing bolt of compressor top and the spot welding nut that compression case covers are tightened mutually, prevents the vibration about the air condition compressor.
See also shown in Figure 1ly, this is the fixing structural representation with the spot welding nut of prior art air-conditioning air condition compressor, and nut top 1 is a round structure, and the bottom 3 of nut is a square structure; Lower end surface in the square bottom 2 of nut forms lower end surface extension 3, and the solder joint 4 of nut is positioned at extension 3 places, nut lower end surface, thereby nut is welded on compressor on the upper shell cover of aircondition by the pressure welding mode.But, in the actual welding of nut, find to exist following point:
Since prior art spot welding nut after pressure welding, screw thread 5 gross distortions in the nut, wherein, preceding two teeth of nut top are easy deformation more;
2. because the solder joint of prior art spot welding nut is positioned at square bottom 2 of nut and lower end surface extension 3 places thereof, thus make welding slag after the welding be deposited in easily nut around, therefore influence the appearance quality of compressor;
Since prior art spot welding nut after cap and nut weld, also must carry out application, but because all seal with cap in welding back nut bottom, the application liquid that produces when making application will remain in the nut, thereby it is a large amount of attached on the screw thread that oven dry back paint is easier to, and therefore influenced the practical effect of nut.
Summary of the invention
The purpose of this utility model is to provide a kind of improved air condition compressor to fix and uses the spot welding nut, and it can prevent the distortion of nut inner thread, and the application liquid when stoping application remains in the nut, thereby guarantees the outward appearance of compressor.
The purpose of this utility model is achieved in that
A kind of air condition compressor is fixing uses the spot welding nut, and comprising: nut top, this nut top are round structure; Outside and the nut bottom that extend downwards along the nut top downside; Be arranged on the internal thread in the nut; Be positioned at the solder joint of nut bottom face; Be characterized in: in described nut bottom one groove is set, this groove is from the setting that caves inward of nut bottom face; Be that the nut top inside bottom is positioned at the internal thread medial extremity nut top step is set in described nut.
In above-mentioned air condition compressor was fixed with the spot welding nut, wherein, the described groove that is arranged on nut lower base inboard was positioned at the diametrical position of nut bottom face.
In above-mentioned air condition compressor was fixed with the spot welding nut, wherein, the described width range that is arranged on the groove of nut lower base inboard was 70 30 percent to percent of the interior circular diameter of nut.
In above-mentioned air condition compressor was fixed with the spot welding nut, wherein, the described width range that is arranged on the nut top step in the nut top was the distance of 1 circle to the screw thread periodontals of 3 circles.
In above-mentioned air condition compressor is fixed with the spot welding nut, wherein, the rounded structure in described nut bottom.
In above-mentioned air condition compressor was fixed with the spot welding nut, wherein, described nut bottom face was a plane.
The utility model air condition compressor fixing with the spot welding nut owing to having adopted technique scheme, make it compared with prior art, have following advantage and good effect:
1. the utility model is owing to open by a groove in nut bottom, thereby can prevent to paint residual on screw thread when application, makes application liquid reserve nut from the fluting source, and the spiral shell that therefore can guarantee the actual use of nut is effect admittedly;
The utility model since with the nut bottom by the square round structure that changes into, thereby can determine number of welds as required, adjust bond pad locations, the even bond pad locations that distributes easily, and, circular nut bottom make solder joint can in move, thereby can reduce the welding slag around the nut, guarantee the outward appearance of compressor;
3. the utility model is owing to be that the nut top inside bottom promptly is positioned at the internal thread medial extremity nut top step is set in nut, thereby reduced the distortion of welding rear thread when making spot welding, thereby makes nut keep original shape.
Description of drawings
To the fixing description of using an embodiment of spot welding nut in conjunction with its accompanying drawing of the utility model air condition compressor, can further understand the purpose of this utility model, specific structural features and advantage by following.Wherein, accompanying drawing is:
Fig. 1 is the fixing structural representation with the spot welding nut of prior art air condition compressor;
Fig. 2 is the fixing side-looking structural representation with the spot welding nut of Fig. 1 prior art air condition compressor;
Fig. 3 is according to the fixing structural representation with the spot welding nut of the air condition compressor that the utility model proposes;
Fig. 4 is the fixing side-looking structural representation with the spot welding nut of the utility model air condition compressor among Fig. 3.
Embodiment
See also Fig. 3 and shown in Figure 4, they are fixing structural representation and side views with the spot welding nut of the utility model air condition compressor.The fixing structure with the spot welding nut of the utility model air condition compressor comprises, nut top 10, nut bottom 20, is arranged on the interior internal thread 30 of nut, is positioned at the solder joint 40 of 20 bottom surfaces, nut bottom.Wherein,
Described nut top 10 is a round structure; Described nut bottom 20 is outside and formation that extend downwards along nut top 10 downsides, and this nut bottom 20 can be square, it also can be other shape, in the present embodiment, nut bottom 20 is round structures, it has changed in the past, and nut bottom 20 is square shape, thereby can determine number of welds as required, also can adjust the bond pad locations and the bond pad locations that can evenly distribute easily, in addition, circular nut bottom 20 make solder joint can in move, thereby can reduce the welding slag around the nut, guarantee the outward appearance of compressor;
