[0027] Example 1
[0028] Combined with Figure 1-5 , this embodiment provides a connection structure, including:
[0029] Thin-walled shell 1;
[0030] A connecting ring 2 threadedly sleeved in the thin-walled shell 1;
[0031] A plurality of first fasteners 31 are all threadedly connected to the connecting ring 2, and one end of the plurality of first fasteners 31 is in contact with the inner wall of the thin-walled shell 1;
[0032] The end cover 4 is detachably connected to one end of the connecting ring 2 , and the end cover 4 contacts one end of the thin-walled shell 1 . The other ends of the first fasteners 31 are all arranged corresponding to the side ends of the end cover 4 .
[0033] Specifically, due to the threaded connection between the connecting ring 2 and the thin-walled shell 1, it is convenient for the connecting ring 2 and the thin-walled shell 1 to achieve relative axial limitation; a plurality of first fasteners 31 are used to achieve relative circumferential limitation between the connecting ring 2 and the thin-walled shell 1, which is equivalent to preventing the connecting ring 2 and the thin-walled shell 1 from rotating relative to each other. The specific number of the plurality of first fasteners 31 is not limited, and can be two, three, etc., preferably two. The first fasteners 31 can be headless screws, countersunk screws, etc., preferably headless screws; since the other ends of the plurality of first fasteners 31 are all arranged corresponding to the side ends of the end cover 4, it is convenient for the end cover 4 to produce a radial limiting effect on the plurality of first fasteners 31, thereby preventing the plurality of first fasteners 31 from separating from the connecting ring 2, thereby ensuring the high reliability of the connection between the connecting ring 2 and the thin-walled shell 1, to ensure the high reliability of the connection between the end cover 4 and the thin-walled shell 1.
[0034] Further, such as Figure 3 , and also includes a plurality of radial threaded holes 21 circumferentially arranged in the connecting ring 2, and the plurality of radial threaded holes 21 and the plurality of first fasteners 31 are correspondingly threadedly connected.
[0035] Specifically, the plurality of radial threaded holes 21 are used to correspondingly accommodate a plurality of first fasteners 31 .
[0036] Further, such as Figure 3 A plurality of radial threaded holes 21 are evenly distributed along the circumference of the connecting ring 2 .
[0037] Specifically, it is equivalent to that a plurality of first fasteners 31 are evenly distributed along the circumference of the connecting ring 2 , so as to facilitate the uniformity of the interaction between the connecting ring 2 and the thin-walled shell 1 .
[0038] Further, such as Figure 3-5 , and also includes a plurality of second fasteners 32 , which are all threadedly connected to one end of the connecting ring 2 , and the plurality of second fasteners 32 are all matched with the end cover 4 .
[0039] Specifically, a plurality of second fasteners 32 facilitate the detachable connection between the connecting ring 2 and the end cover 4. The specific number of the plurality of second fasteners 32 is not limited and may be three, four, etc., preferably three. The second fasteners 32 may be countersunk screws, semi-countersunk screws, etc.
[0040] Further, such as Figure 5 , and also includes a plurality of axial step holes 41 circumferentially arranged on the end cover 4, the rod portions 321 of the plurality of second fasteners 32 correspondingly pass through the plurality of axial step holes 41, and the heads 322 of the plurality of second fasteners 32 are in corresponding contact with the step portions 411 of the plurality of axial step holes 41.
[0041] Specifically, the plurality of axial step holes 41 are used to correspondingly accommodate a plurality of second fasteners 32 .
[0042] Further, such as Figure 5 The heights of the heads 322 of the second fasteners 32 are all lower than the height of the end of the end cover 4 away from the connecting ring 2 .
[0043] Specifically, the height of the heads 322 of the second fasteners 32 is relatively small, and the height of the end of the end cover 4 away from the connecting ring 2 is relatively large, so as to ensure the flatness of the plane where the end of the end cover 4 away from the connecting ring 2 is located.
[0044] Further, such as Figure 5 , the plurality of axial step holes 41 are all waist-shaped along the circumferential direction.
[0045] Specifically, the plurality of waist-shaped axial step holes 41 facilitate adjustment of the installation position of the end cover 4 according to needs.
[0046] This embodiment also provides a thin-walled shell motor, including a connection structure in this embodiment.
[0047] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
