[0050] The present invention will be further described below with reference to the accompanying drawings.

[0051] The compressor is a core component of refrigeration equipment, and its capabilities and characteristics determine those of the equipment. Rotary compressors, in particular, are widely used in the refrigeration field due to their high stability, high efficiency, and compact size. Rotary compressors are typically used in systems such as air conditioners and refrigerators. In some cases, the energy efficiency and noise levels of a rotary compressor meet the requirements of the application system, but the compressor's mounting angle does not meet the requirements of the different application systems. Furthermore, due to limited space within the application system, adjusting the compressor's mounting angle is inconvenient, requiring the redevelopment of the housing assembly. This results in high development frequency and high costs for the same compressor model.

[0052] Example 1

[0053] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the utility model provides a shell structure, including a shell 10, a support assembly 20 and a locking assembly 30; the support assembly 20 is rotatably arranged on the outer wall of the shell 10, so that the shell 10 can rotate axially relative to the support assembly 20, and the support assembly 20 is constructed to support the shell 10; the locking assembly 30 is constructed to be able to rotate up and down relative to the shell 10; wherein, when the locking assembly 30 is rotated upward to a locking state, it abuts against the support assembly 20 and the shell 10 respectively to fix the shell 10 and limit the relative rotation of the shell 10 and the support assembly 20; when the locking assembly 30 is rotated downward to an adjustment state, the shell 10 can rotate relative to the support assembly 20.

[0054] As can be seen from the above, by arranging a rotatable support assembly 20 on the shell 10, not only can the shell 10 be supported and loaded, but the installation angle of the shell 10 can also be adjusted by utilizing the relative rotation of the shell 10 and the support assembly 20, so that the installation angle of the shell 10 can be smoothly adjusted in a narrow space; in addition, when the shell structure is assembled in different application systems, the shell 10 can be rotated according to the assembly requirements and usage requirements so that the installation angle of the shell 10 meets the requirements of different application systems, thereby successfully completing the assembly without the need to develop a new shell structure. This not only expands the application occasions of the shell structure, but also reduces the development frequency of shell assemblies for compressors of the same model, reduces development costs, and reduces repetitive work. By setting a locking assembly 30 to fix the shell 10, the relative rotation of the shell 10 and the support assembly 20 is limited, thereby preventing the installation angle of the shell 10 from changing; when the shell 10 is rotated to the installation angle, the locking assembly 30 is rotated upward to the locking state, and the locking assembly 30 is respectively abutted against the support assembly 20 and the shell 10 to fix the position of the shell 10, thereby preventing the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system; when the locking assembly 30 is rotated downward to the adjustment state, the locking assembly 30 no longer abuts against the outer walls of the support assembly 20 and the shell 10, so that the shell 10 can be rotated relative to the support assembly 20 and the installation angle is readjusted.

[0055] It should be noted that the shell 10 includes an upper cover, on which are provided U / V / W three-phase terminals, so the rotation angle of the shell 10 also determines the angle of the upper cover, which is closely related to the wiring angle; therefore, the shell 10 can be rotated to ensure that the wiring is at a reasonable angle.

[0056] It should also be noted that a fixing seat for mounting the liquid dispenser is provided on the outer wall of the housing 10 .

[0057] Example 2

[0058] like Figure 1 As shown, the shell structure includes a shell 10, a support assembly 20 and a locking assembly 30; the support assembly 20 is rotatably arranged on the outer wall of the shell 10 so that the shell 10 can rotate axially relative to the support assembly 20, and the support assembly 20 is constructed to support the shell 10; the locking assembly 30 is constructed to be rotatable up and down relative to the shell 10; wherein, when the locking assembly 30 is rotated upward to a locking state, it abuts against the support assembly 20 and the shell 10 respectively to fix the shell 10 and limit the relative rotation of the shell 10 and the support assembly 20; when the locking assembly 30 is rotated downward to an adjustment state, the shell 10 can rotate relative to the support assembly 20.

[0059] As can be seen from the above, by arranging a rotatable support assembly 20 on the shell 10, not only can the shell 10 be supported and loaded, but the installation angle of the shell 10 can also be adjusted by utilizing the relative rotation of the shell 10 and the support assembly 20, so that the installation angle of the shell 10 can be smoothly adjusted in a narrow space; in addition, when the shell structure is assembled in different application systems, the shell 10 can be rotated according to the assembly requirements and usage requirements so that the installation angle of the shell 10 meets the requirements of different application systems, thereby successfully completing the assembly without the need to develop a new shell structure. This not only expands the application occasions of the shell structure, but also reduces the development frequency of shell assemblies for compressors of the same model, reduces development costs, and reduces repetitive work. By setting a locking assembly 30 to fix the shell 10, the relative rotation of the shell 10 and the support assembly 20 is limited, thereby preventing the installation angle of the shell 10 from changing; when the shell 10 is rotated to the installation angle, the locking assembly 30 is rotated upward to the locking state, and the locking assembly 30 is respectively abutted against the support assembly 20 and the shell 10 to fix the position of the shell 10, thereby preventing the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system; when the locking assembly 30 is rotated downward to the adjustment state, the locking assembly 30 no longer abuts against the outer walls of the support assembly 20 and the shell 10, so that the shell 10 can be rotated relative to the support assembly 20 and the installation angle is readjusted.

[0060] It should be noted that the shell 10 includes an upper cover, on which are provided U / V / W three-phase terminals, so the rotation angle of the shell 10 also determines the angle of the upper cover, which is closely related to the wiring angle; therefore, the shell 10 can be rotated to ensure that the wiring is at a reasonable angle.

[0061] It should also be noted that a fixing seat for mounting the liquid dispenser is provided on the outer wall of the housing 10 .

[0062] like Figure 1 、 Figure 2 As shown, in some embodiments, the locking assembly 30 includes a plurality of claws 310 arranged circumferentially around the shell 10, and the claws 310 include a head 3101 and a tail 3102; the head 3101 is rotatably disposed on the shell 10 or the support assembly 20; the tail 3102 is connected to the head 3101, and the tail 3102 includes a connected first clamping segment 3103 and a second clamping segment 3104; wherein the first clamping segment 3103 is a circular arc segment, and the second clamping segment 3104 is a straight line segment.

[0063] In the locked state, the tail portion 3102 abuts against the support assembly 20 and the housing 10 to fix the housing 10. The first clamping section 3103 of the circular arc segment is provided to prevent the tail portion 3102 from interfering with the housing 10 and the support assembly 20 during rotation, thereby preventing locking.

[0064] It should be noted that, in the locked state, the tail portion 3102 is in close contact with the upper end surface of the outer ring body 210 and maintains an interference fit, thereby preventing the claw 310 from loosening and rotating downward, resulting in the inability to maintain the locked state.

[0065] It should be noted that the number of the claws 310 is set according to actual needs, and the plurality of claws 310 are arranged at equal intervals around the circumference of the housing 10; Figure 1 As shown, there are three claws 310 , which are arranged at equal intervals around the housing 10 circumferentially, and the angle between two adjacent claws 310 is 120°.

[0066] It should also be noted that if Figure 2 As shown, an inclined section 3106 is provided on the side of the claw 310 opposite to the head 3101, and an angle is formed between the inclined section 3106 and the second clamping section 3104, and the angle is less than 90°; a vertical section 3107 is provided on the side of the claw 310 opposite to the tail 3102, and the vertical section 3107 is perpendicular to the second clamping section 3104.

[0067] Example 3

[0068] like Figure 1 As shown, the shell structure includes a shell 10, a support assembly 20 and a locking assembly 30; the support assembly 20 is rotatably arranged on the outer wall of the shell 10 so that the shell 10 can rotate axially relative to the support assembly 20, and the support assembly 20 is constructed to support the shell 10; the locking assembly 30 is constructed to be rotatable up and down relative to the shell 10; wherein, when the locking assembly 30 is rotated upward to a locking state, it abuts against the support assembly 20 and the shell 10 respectively to fix the shell 10 and limit the relative rotation of the shell 10 and the support assembly 20; when the locking assembly 30 is rotated downward to an adjustment state, the shell 10 can rotate relative to the support assembly 20.

[0069] As can be seen from the above, by arranging a rotatable support assembly 20 on the shell 10, not only can the shell 10 be supported and loaded, but the installation angle of the shell 10 can also be adjusted by utilizing the relative rotation of the shell 10 and the support assembly 20, so that the installation angle of the shell 10 can be smoothly adjusted in a narrow space; in addition, when the shell structure is assembled in different application systems, the shell 10 can be rotated according to the assembly requirements and usage requirements so that the installation angle of the shell 10 meets the requirements of different application systems, thereby successfully completing the assembly without the need to develop a new shell structure. This not only expands the application occasions of the shell structure, but also reduces the development frequency of shell assemblies for compressors of the same model, reduces development costs, and reduces repetitive work. By setting a locking assembly 30 to fix the shell 10, the relative rotation of the shell 10 and the support assembly 20 is limited, thereby preventing the installation angle of the shell 10 from changing; when the shell 10 is rotated to the installation angle, the locking assembly 30 is rotated upward to the locking state, and the locking assembly 30 is respectively abutted against the support assembly 20 and the shell 10 to fix the position of the shell 10, thereby preventing the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system; when the locking assembly 30 is rotated downward to the adjustment state, the locking assembly 30 no longer abuts against the outer walls of the support assembly 20 and the shell 10, so that the shell 10 can be rotated relative to the support assembly 20 and the installation angle is readjusted.

[0070] It should be noted that the shell 10 includes an upper cover, on which are provided U / V / W three-phase terminals, so the rotation angle of the shell 10 also determines the angle of the upper cover, which is closely related to the wiring angle; therefore, the shell 10 can be rotated to ensure that the wiring is at a reasonable angle.

[0071] It should also be noted that a fixing seat for mounting the liquid dispenser is provided on the outer wall of the housing 10 .

[0072] like Figure 1 、 Figure 2 As shown, in some embodiments, the locking assembly 30 includes a plurality of claws 310 arranged circumferentially around the shell 10, and the claws 310 include a head 3101 and a tail 3102; the head 3101 is rotatably disposed on the shell 10 or the support assembly 20; the tail 3102 is connected to the head 3101, and the tail 3102 includes a connected first clamping segment 3103 and a second clamping segment 3104; wherein the first clamping segment 3103 is a circular arc segment, and the second clamping segment 3104 is a straight line segment.

[0073] In the locked state, the tail portion 3102 abuts against the support assembly 20 and the housing 10 to fix the housing 10. The first clamping section 3103 of the circular arc segment is provided to prevent the tail portion 3102 from interfering with the housing 10 and the support assembly 20 during rotation, thereby preventing locking.

[0074] It should be noted that, in the locked state, the tail portion 3102 is in close contact with the upper end surface of the outer ring body 210 and maintains an interference fit, thereby preventing the claw 310 from loosening and rotating downward, resulting in the inability to maintain the locked state.

[0075] It should be noted that the number of the claws 310 is set according to actual needs, and the plurality of claws 310 are arranged at equal intervals around the circumference of the housing 10; Figure 1 As shown, there are three claws 310 , which are arranged at equal intervals around the housing 10 circumferentially, and the angle between two adjacent claws 310 is 120°.

[0076] It should also be noted that if Figure 2 As shown, an inclined section 3106 is provided on the side of the claw 310 opposite to the head 3101, and an angle is formed between the inclined section 3106 and the second clamping section 3104, and the angle is less than 90°; a vertical section 3107 is provided on the side of the claw 310 opposite to the tail 3102, and the vertical section 3107 is perpendicular to the second clamping section 3104.

[0077] like Figure 3-Figure 7 As shown, in some embodiments, the support assembly 20 includes an outer ring body 210, a plurality of rotating bodies 220 and a plurality of support seats 230; the outer ring body 210 is mounted on the outside of the shell 10; the plurality of rotating bodies 220 are arranged circumferentially at intervals around the shell 10, and the rotating bodies 220 are rotatably connected to the outer ring body 210 and the shell 10 respectively; the plurality of support seats 230 are arranged on the outer wall of the outer ring body 210, and the plurality of support seats 230 are arranged circumferentially at intervals around the outer ring body 210.

[0078] By providing multiple rotating bodies 220 that are rotatably connected to the outer ring body 210 and the housing 10, the housing 10 can rotate relative to the outer ring body 210, thereby facilitating adjustment of the installation angle of the housing 10. When the housing structure is assembled in different application systems, the housing 10 can be rotated according to assembly and use requirements to ensure that the installation angle of the housing 10 meets the requirements of different application systems. By providing multiple support bases 230, the housing structure is supported.

[0079] It should be noted that the rotating body 220 is spherical, and the number of the rotating bodies 220 is not less than 9, so as to reduce the risk of the outer ring body 210 falling off.

[0080] It should also be noted that the support seat 230 is connected to the outer wall of the outer ring body 210 by means of welding or screw connection, including but not limited to; in addition, a plurality of support seats 230 are arranged at equal intervals around the outer ring body 210, and a plurality of support seats 230 and a plurality of claws 310 are arranged at staggered intervals in the circumferential direction of the outer ring body 210, and the claws 310 are located between two adjacent support seats 230, thereby avoiding interference between the claws 310 and the support seats 230; Figure 1 As shown, there are three support seats 230 and three claws 310 , and the claws 310 are located between two adjacent support seats 230 . The angles between the claws 310 and the two adjacent support seats 230 are both 60°, thereby effectively avoiding and preventing interference.

[0081] It should also be noted that the support assembly 20 further includes a plurality of foot pads, which correspond one to one with the plurality of support seats 230, and the foot pads are mounted on the corresponding support seats 230; when the shell structure is placed vertically, the foot pads are in contact with the ground; in addition, as Figure 12 As shown, there is a distance P1 between the support base 230 and the bottom of the support assembly 20, and P1 is 8 mm.

[0082] like Figure 3 、 Figure 4 As shown, in some embodiments, an annular groove 110 is provided on the outer wall of the shell 10, and a plurality of first grooves are provided on the inner wall of the outer ring body 210. The plurality of first grooves are arranged circumferentially around the outer ring body 210 and correspond one-to-one to the plurality of rotating bodies 220 respectively; wherein, the two sides of the rotating body 220 are respectively rotatably provided in the annular groove 110 and the corresponding first grooves.

[0083] By respectively providing the annular groove 110 and the first groove on the housing 10 and the outer ring body 210 , a structural basis is provided for the rotational connection between the rotating body 220 and the housing 10 and the outer ring body 210 .

[0084] It should be noted that the cross section of the annular groove 110 is arc-shaped, and the first groove is spherical. The annular groove 110 and the first groove are respectively matched with the shapes of the rotating body 220.

[0085] It should also be noted that, in some embodiments, when the shell 10 is rotated to the installation angle in the application system, the annular groove 110 and the first groove can be welded to the rotating body 220 respectively, so as to fix the position of the shell 10 and prevent the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system. However, such locking method will make it impossible to rotate the shell 10 again to adjust the installation angle.

[0086] like Figure 5-Figure 7As shown, in some embodiments, the support assembly 20 also includes an inner ring body 240 arranged on the outer wall of the shell 10, and a plurality of second grooves 2401 are provided on the outer wall of the inner ring body 240, and the plurality of second grooves 2401 are arranged circumferentially at intervals around the inner ring body 240 and respectively correspond to the plurality of rotating bodies 220; a plurality of third grooves 2101 are provided on the inner wall of the outer ring body 210, and the plurality of third grooves 2101 are arranged circumferentially at intervals around the outer ring body 210 and respectively correspond to the plurality of rotating bodies 220; wherein, the two sides of the rotating body 220 are respectively rotatably arranged in the corresponding second grooves 2401 and third grooves 2101.

[0087] By respectively providing the second groove 2401 and the third groove 2101 on the inner ring body 240 and the outer ring body 210 , a structural basis is provided for the rotational connection between the rotating body 220 and the inner ring body 240 and the outer ring body 210 .

[0088] It should be noted that the second groove 2401 and the third groove 2101 are both spherical, and the second groove 2401 and the third groove 2101 are respectively matched with the shape of the rotating body 220; in addition, the inner ring body 240 is connected to the shell 10 including but not limited to welding.

[0089] It should also be noted that, in some embodiments, when the shell 10 is rotated to the installation angle in the application system, the second groove 2401 and the third groove 2101 can be welded to the rotating body 220 respectively, so as to fix the position of the shell 10 and prevent the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system. However, such locking method will make it impossible to rotate the shell 10 again to adjust the installation angle.

[0090] It should also be noted that if Figure 3 、 Figure 5 、 Figure 12 As shown, the inner diameter of the inner ring body 240 is d1, the outer diameter of the inner ring body 240 is d2, the inner diameter of the outer ring body 210 is d3, the outer diameter of the outer ring body 210 is d4, the diameter of the rotating body 220 is d5, the outer diameter of the housing 10 is d6, the depth of the second groove 2401 is h1, the depth of the third groove 2101 is h2, the diameters of the second groove 2401 and the third groove 2101 are both d7, the depth of the annular groove 110 is h3, and the diameter of the annular groove 110 is d8, wherein d1, d2, d3, d4, d5, d6, d7, d8, h1, h2, and h3 satisfy the following relationship:

[0091] d1=d6+0.5, d2≥d1+5, d3=d2+d5 / 3, d4≥d3+5, d5 / 4≥h1=h2≥d5 / 6, d5+3≥d7≥d5+1;

[0092] d5 / 4≥h3=h1=h2≥d5 / 6;

[0093] d5+3≥d8=d7≥d5+1;

[0094] The above relationship ensures that the installation requirements are met, which facilitates the assembly of the support assembly 20 and the matching of the support assembly 20 with the housing 10.

[0095] Example 4

[0096] like Figure 1 As shown, the shell structure includes a shell 10, a support assembly 20 and a locking assembly 30; the support assembly 20 is rotatably arranged on the outer wall of the shell 10 so that the shell 10 can rotate axially relative to the support assembly 20, and the support assembly 20 is constructed to support the shell 10; the locking assembly 30 is constructed to be rotatable up and down relative to the shell 10; wherein, when the locking assembly 30 is rotated upward to a locking state, it abuts against the support assembly 20 and the shell 10 respectively to fix the shell 10 and limit the relative rotation of the shell 10 and the support assembly 20; when the locking assembly 30 is rotated downward to an adjustment state, the shell 10 can rotate relative to the support assembly 20.

[0097] As can be seen from the above, by arranging a rotatable support assembly 20 on the shell 10, not only can the shell 10 be supported and loaded, but the installation angle of the shell 10 can also be adjusted by utilizing the relative rotation of the shell 10 and the support assembly 20, so that the installation angle of the shell 10 can be smoothly adjusted in a narrow space; in addition, when the shell structure is assembled in different application systems, the shell 10 can be rotated according to the assembly requirements and usage requirements so that the installation angle of the shell 10 meets the requirements of different application systems, thereby successfully completing the assembly without the need to develop a new shell structure. This not only expands the application occasions of the shell structure, but also reduces the development frequency of shell assemblies for compressors of the same model, reduces development costs, and reduces repetitive work. By setting a locking assembly 30 to fix the shell 10, the relative rotation of the shell 10 and the support assembly 20 is limited, thereby preventing the installation angle of the shell 10 from changing; when the shell 10 is rotated to the installation angle, the locking assembly 30 is rotated upward to the locking state, and the locking assembly 30 is respectively abutted against the support assembly 20 and the shell 10 to fix the position of the shell 10, thereby preventing the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system; when the locking assembly 30 is rotated downward to the adjustment state, the locking assembly 30 no longer abuts against the outer walls of the support assembly 20 and the shell 10, so that the shell 10 can be rotated relative to the support assembly 20 and the installation angle is readjusted.

[0098] It should be noted that the shell 10 includes an upper cover, on which are provided U / V / W three-phase terminals, so the rotation angle of the shell 10 also determines the angle of the upper cover, which is closely related to the wiring angle; therefore, the shell 10 can be rotated to ensure that the wiring is at a reasonable angle.

[0099] It should also be noted that a fixing seat for mounting the liquid dispenser is provided on the outer wall of the housing 10 .

[0100] like Figure 1 、 Figure 2 As shown, in some embodiments, the locking assembly 30 includes a plurality of claws 310 arranged circumferentially around the shell 10, and the claws 310 include a head 3101 and a tail 3102; the head 3101 is rotatably disposed on the shell 10 or the support assembly 20; the tail 3102 is connected to the head 3101, and the tail 3102 includes a connected first clamping segment 3103 and a second clamping segment 3104; wherein the first clamping segment 3103 is a circular arc segment, and the second clamping segment 3104 is a straight line segment.

[0101] In the locked state, the tail portion 3102 abuts against the support assembly 20 and the housing 10 to fix the housing 10. The first clamping section 3103 of the circular arc segment is provided to prevent the tail portion 3102 from interfering with the housing 10 and the support assembly 20 during rotation, thereby preventing locking.

[0102] It should be noted that, in the locked state, the tail portion 3102 is in close contact with the upper end surface of the outer ring body 210 and maintains an interference fit, thereby preventing the claw 310 from loosening and rotating downward, resulting in the inability to maintain the locked state.

[0103] It should be noted that the number of the claws 310 is set according to actual needs, and the plurality of claws 310 are arranged at equal intervals around the circumference of the housing 10; Figure 1 As shown, there are three claws 310 , which are arranged at equal intervals around the housing 10 circumferentially, and the angle between two adjacent claws 310 is 120°.

[0104] It should also be noted that if Figure 2 As shown, an inclined section 3106 is provided on the side of the claw 310 opposite to the head 3101, and an angle is formed between the inclined section 3106 and the second clamping section 3104, and the angle is less than 90°; a vertical section 3107 is provided on the side of the claw 310 opposite to the tail 3102, and the vertical section 3107 is perpendicular to the second clamping section 3104.

[0106] By providing multiple rotating bodies 220 that are rotatably connected to the outer ring body 210 and the housing 10, the housing 10 can rotate relative to the outer ring body 210, thereby facilitating adjustment of the installation angle of the housing 10. When the housing structure is assembled in different application systems, the housing 10 can be rotated according to assembly and use requirements to ensure that the installation angle of the housing 10 meets the requirements of different application systems. By providing multiple support bases 230, the housing structure is supported.

[0107] It should be noted that the rotating body 220 is spherical, and the number of the rotating bodies 220 is not less than 9, so as to reduce the risk of the outer ring body 210 falling off.

[0108] It should also be noted that the support seat 230 is connected to the outer wall of the outer ring body 210 by means of welding or screw connection, including but not limited to; in addition, a plurality of support seats 230 are arranged at equal intervals around the outer ring body 210, and a plurality of support seats 230 and a plurality of claws 310 are arranged at staggered intervals in the circumferential direction of the outer ring body 210, and the claws 310 are located between two adjacent support seats 230, thereby avoiding interference between the claws 310 and the support seats 230; Figure 1 As shown, there are three support seats 230 and three claws 310 , and the claws 310 are located between two adjacent support seats 230 . The angles between the claws 310 and the two adjacent support seats 230 are both 60°, thereby effectively avoiding and preventing interference.

[0109] It should also be noted that the support assembly 20 further includes a plurality of foot pads, which correspond one to one with the plurality of support seats 230, and the foot pads are mounted on the corresponding support seats 230; when the shell structure is placed vertically, the foot pads are in contact with the ground; in addition, as Figure 12 As shown, there is a distance P1 between the support base 230 and the bottom of the support assembly 20, and P1 is 8 mm.

[0111] By respectively providing the annular groove 110 and the first groove on the housing 10 and the outer ring body 210 , a structural basis is provided for the rotational connection between the rotating body 220 and the housing 10 and the outer ring body 210 .

[0112] It should be noted that the cross section of the annular groove 110 is arc-shaped, and the first groove is spherical. The annular groove 110 and the first groove are respectively matched with the shapes of the rotating body 220.

[0113] It should also be noted that, in some embodiments, when the shell 10 is rotated to the installation angle in the application system, the annular groove 110 and the first groove can be welded to the rotating body 220 respectively, so as to fix the position of the shell 10 and prevent the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system. However, such locking method will make it impossible to rotate the shell 10 again to adjust the installation angle.

[0114] like Figure 5-Figure 7 As shown, in some embodiments, the support assembly 20 also includes an inner ring body 240 arranged on the outer wall of the shell 10, and a plurality of second grooves 2401 are provided on the outer wall of the inner ring body 240, and the plurality of second grooves 2401 are arranged circumferentially at intervals around the inner ring body 240 and respectively correspond to the plurality of rotating bodies 220; a plurality of third grooves 2101 are provided on the inner wall of the outer ring body 210, and the plurality of third grooves 2101 are arranged circumferentially at intervals around the outer ring body 210 and respectively correspond to the plurality of rotating bodies 220; wherein, the two sides of the rotating body 220 are respectively rotatably arranged in the corresponding second grooves 2401 and third grooves 2101.

[0115] By respectively providing the second groove 2401 and the third groove 2101 on the inner ring body 240 and the outer ring body 210 , a structural basis is provided for the rotational connection between the rotating body 220 and the inner ring body 240 and the outer ring body 210 .

[0116] It should be noted that the second groove 2401 and the third groove 2101 are both spherical, and the second groove 2401 and the third groove 2101 are respectively matched with the shape of the rotating body 220; in addition, the inner ring body 240 is connected to the shell 10 including but not limited to welding.

[0117] It should also be noted that, in some embodiments, when the shell 10 is rotated to the installation angle in the application system, the second groove 2401 and the third groove 2101 can be welded to the rotating body 220 respectively, so as to fix the position of the shell 10 and prevent the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system. However, such locking method will make it impossible to rotate the shell 10 again to adjust the installation angle.

[0118] It should also be noted that if Figure 3 、 Figure 5 、 Figure 12 As shown, the inner diameter of the inner ring body 240 is d1, the outer diameter of the inner ring body 240 is d2, the inner diameter of the outer ring body 210 is d3, the outer diameter of the outer ring body 210 is d4, the diameter of the rotating body 220 is d5, the outer diameter of the housing 10 is d6, the depth of the second groove 2401 is h1, the depth of the third groove 2101 is h2, the diameters of the second groove 2401 and the third groove 2101 are both d7, the depth of the annular groove 110 is h3, and the diameter of the annular groove 110 is d8, wherein d1, d2, d3, d4, d5, d6, d7, d8, h1, h2, and h3 satisfy the following relationship:

[0121] d5+3≥d8=d7≥d5+1;

[0122] The above relationship ensures that the installation requirements are met, which facilitates the assembly of the support assembly 20 and the matching of the support assembly 20 with the housing 10.

[0123] like Figure 1 、 Figures 8-10 As shown, in some embodiments, a plurality of first clearance grooves 120 are provided at the bottom of the shell 10, and the plurality of first clearance grooves 120 correspond one-to-one to the plurality of claws 310, and a first mounting hole 130 is provided in each first clearance groove 120; wherein, the claw 310 is rotatably connected to the first mounting hole 130 in the corresponding first clearance groove 120 through a pin shaft 320.

By setting a locking assembly 30 to fix the shell 10, the relative rotation of the shell 10 and the support assembly 20 is limited, thereby preventing the installation angle of the shell 10 from changing; when the shell 10 is rotated to the installation angle, the locking assembly 30 is rotated upward to the locking state, and the locking assembly 30 is respectively abutted against the support assembly 20 and the shell 10 to fix the position of the shell 10, thereby preventing the shell 10 from continuing to rotate, resulting in failure to meet the installation angle requirements of the application system; when the locking assembly 30 is rotated downward to the adjustment state, the locking assembly 30 no longer abuts against the outer walls of the support assembly 20 and the shell 10, so that the shell 10 can be rotated relative to the support assembly 20 and the installation angle is readjusted.

[0133] It should be noted that the shell 10 includes an upper cover, on which are provided U / V / W three-phase terminals, so the rotation angle of the shell 10 also determines the angle of the upper cover, which is closely related to the wiring angle; therefore, the shell 10 can be rotated to ensure that the wiring is at a reasonable angle.

When the housing structure is assembled in different application systems, the housing 10 can be rotated according to assembly and use requirements to ensure that the installation angle of the housing 10 meets the requirements of different application systems. By providing multiple support bases 230, the housing structure is supported.
