Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to the accompanying drawings the screw 100 for compressor according to the utility model embodiment is described.
As Figure 1-Figure 4, the hand of spiral of the first external screw thread 110 and the second external screw thread 120, first external screw thread 110 and the second external screw thread 120 is provided with according to the screw 100 for compressor of the utility model embodiment contrary.
According to the screw 100 for compressor of the utility model embodiment, by arranging the first external screw thread 110 and the second external screw thread 120 on screw 100, and the hand of spiral of the first external screw thread 110 and the second external screw thread 120 is contrary, screw 100 is utilized to install described compressor like this, when a generation in the first external screw thread 110 and the second external screw thread 120 loosens, because the hand of spiral of the first external screw thread 110 and the second external screw thread 120 is contrary, another in first external screw thread 110 and the second external screw thread 120 can be locked, in other words, when the first external screw thread 110 occurs to loosen, second external screw thread 120 can be locked, when the second external screw thread 120 loosens, first external screw thread 110 can be locked, thus the self-locking of screw 100 can be realized, ensure the positional precision of the parts connected by screw 100, such as, frame and the stator of described compressor is connected by screw 100, the positional precision of the stator of described compressor can be ensured, prevent described compressor because of vibration or be subject to shock and cause screw loosening and cause rotor gap to change, ensure the reliability of described compressor.
And, described compressor only need be undertaken installing the positional precision that can ensure the parts connected by screw 100 by screw 100, and without the need to additionally arranging other structures for positioning described compressor, the structure of compressor can be made simpler, cost is lower, and due to screw 100 can not because using for a long time time vibration and loosen, the frequency of maintenance of described compressor can be reduced, improve the service life of described compressor.
Therefore, auto-lock function can be realized according to the screw 100 for compressor of the utility model embodiment, improve the reliability of compressor, have and not easily loosen, connect the advantages such as reliable.
Below with reference to the accompanying drawings the screw 100 for compressor according to the utility model specific embodiment is described.
In specific embodiments more of the present utility model, as Figure 1-Figure 4, the hand of spiral being provided with the first external screw thread 110 and the second external screw thread 120, first external screw thread 110 and the second external screw thread 120 according to the screw 100 for compressor of the utility model embodiment is contrary.
One end of screw 100 can have nut 130, and the first external screw thread 110 can be positioned at the other end of screw 100.Nut 130 can be utilized thus to position, facilitate the use screw 100 and connect, and can so that control the length of screw 100.
Particularly, as shown in Figure 1, the second external screw thread 120 can be connected with the first external screw thread 110.Thus not only can so that the installation of screw 100, and can so that control the length of screw 100.
Advantageously, as shown in Figure 1, the external diameter of the first external screw thread 110 can be less than the internal diameter of the second external screw thread 120.Part screw 100 with the first external screw thread 110 can be enable thus to pass through the screw thread coordinated with the second external screw thread 120, thus can so that the installation of screw 100.
Alternatively, as shown in Figure 1, the first external screw thread 110 can be equal with the moment of torsion of the second external screw thread 120.Not only can make the stressed more even of screw 100 thus, and can at described vibration of compressor or when being subject to impacting, when loosening second external screw thread 120 of the first external screw thread 110 is locked, the pitch that first external screw thread 110 is lost is equal with the pitch that the second external screw thread 120 obtains, the first external screw thread 110 lock the second external screw thread 120 loosen time, the pitch that first external screw thread 110 is obtained is equal with the pitch that the second external screw thread 120 loses, thus make stressed the remaining unchanged of screw 100 entirety, thus improve stability and the reliability of described compressor further.
Specifically, the first external screw thread 110 and the second external screw thread 120 also can lay respectively at the two ends of screw, can realize equally connecting the parts of described compressor,
Compressor 1 according to the utility model embodiment is described below.Frame 200, stator 300, nut 400 and screw is comprised according to the compressor 1 of the utility model embodiment.
At least one in frame 200 and stator 300 is provided with the second internal thread.Nut 400 has the first internal thread.Described screw is the screw 100 for compressor according to the utility model above-described embodiment.Frame 200 is connected with nut 400 by screw 100 with stator 300, the first external screw thread 110 and described first screw-internal thread fit, the second external screw thread 120 and described second screw-internal thread fit.
According to the compressor 1 of the utility model embodiment, by utilizing the screw 100 for compressor according to the utility model above-described embodiment, the positional precision of stator 300 in frame 200 can be ensured, thus ensure the stability in rotor gap, have that reliability is strong, rotor gap is stable, low cost and other advantages.
Below with reference to the accompanying drawings compressor 1 according to the utility model specific embodiment is described.
In specific embodiments more of the present utility model, as Figure 1-Figure 4, frame 200, stator 300, nut 400 and screw is comprised according to the compressor 1 of the utility model embodiment.
One end of screw 100 can have nut 130, and the other end of screw 100 can be engaged in nut 400 through frame 200 and stator 300, and frame 200 and stator 300 can be clamped between nut 130 and nut 400.Nut 130 and nut 400 pairs of frames 200 and stator 300 can be utilized thus to position, not only can improve the bonding strength of stator 300 and frame 200, and the stability of stator 300 in frame 200 can be improved further.
Particularly, as shown in figs 2-4, stator 300 can be provided with screw via hole, frame 200 can be provided with screw mounting hole, described second internal thread can be formed on the internal perisporium of described screw mounting hole, and screw 100 can pass described screw via hole and the second external screw thread 120 and described second screw-internal thread fit.Thus not only can so that the formation of described second internal thread, and can so that the described other end of screw 100 through described screw via hole and described screw mounting hole to make the first external screw thread 110 and described first screw-internal thread fit, make the second external screw thread 120 and described second screw-internal thread fit.
Alternatively, as shown in figs 2-4, screw 100 can be that multiple and multiple screw 100 can be arranged along the circumferential interval of stator 300.Specifically, nut 400 can be multiple, and each nut 400 is engaged in the described other end of each screw 100 respectively.Multiple screw 100 and nut 400 pairs of frames 200 and stator 300 can be utilized thus to be fixed, not only can improve the bonding strength of frame 200 and stator 300, and the stressed more even of stator 300 can be made, thus improve the stability of stator 300 in frame 200 further.
