Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, such as a compressor and refrigeration equipment. Background Technology

[0002] A compressor includes a housing and a stator and a rotor housed within the housing. It operates and performs work through electromagnetic induction between the stator and the rotor. The stator is typically fixed to the housing using a heat-shrink fitting process, allowing for a tight interference fit between the stator and the housing.

[0003] However, the heat-shrink assembly method results in a large contact area between the inner wall of the housing and the outer wall of the stator. Because different parts of the housing cool at different rates after heating, the stator may also deform differently, affecting motor efficiency and noise. To address this issue, related technologies provide a compressor including a housing, a stator, and at least one support structure. The support structure is connected to the stator and fixedly connected to the housing, creating a gap between the outer peripheral wall of the stator and the inner peripheral wall of the housing. This prevents direct contact between the stator and the housing, reducing vibration transmission between them and thus decreasing noise generated by housing vibration.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Because the wiring angles of the power cords and compressor cover terminals differ between different devices, compressors of the same specification and model may have multiple different cover assembly angles. Furthermore, due to the wiring limitations between the stator leads and the cover terminals, the angle between the root of the stator lead and the cover terminal is within a fixed range. Therefore, the assembly angle of the stator leads needs to be adjusted to match the assembly angle of the cover. In some compressors, the stator angle cannot be adjusted after assembly with the housing, making it impossible to adjust the root angle of the stator leads. During compressor production and assembly, different stator assembly fixtures with varying angles are used, increasing assembly costs and time, thus impacting production efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a compressor and refrigeration equipment that allows the stator inside the compressor to be adjusted to a set angle, thereby adjusting the root angle of the stator lead wires, reducing the corresponding assembly cost and time cost, and thus improving production efficiency.

[0009] In some embodiments, the compressor includes a housing, a stator, and a limiting device. The housing has a first groove on its inner sidewall along its vertical direction; the stator is rotatably disposed within the housing via a rotating assembly, wherein one or more second grooves are circumferentially disposed on the outer sidewall of the stator along its vertical direction; the limiting device includes a fixing part movably disposed within the first groove and a limiting part connected to the fixing part, the fixing part and the limiting part moving synchronously, wherein when the stator rotates to a set position, moving the fixing part of the limiting device causes the limiting part to enter the second groove, and fixing the fixing part causes the limiting part to fix the stator.

[0010] In some embodiments, the fixing part is fixedly connected to the limiting part by an arc-shaped telescopic member.

[0011] In some embodiments, the arc-shaped telescopic member includes an arc-shaped inner core and an arc-shaped outer shell. The arc-shaped inner core is fixedly connected to a fixing part or a limiting part; the arc-shaped outer shell is sleeved on the arc-shaped inner core and is fixedly connected to the limiting part or the fixing part.

[0012] In some embodiments, a first fixing hole is provided on the outer side of the arc-shaped outer shell, and the arc-shaped telescopic member further includes: a first locking member, which is disposed in the first fixing hole and abuts against the arc-shaped inner core.

[0013] In some embodiments, the center of the arc-shaped telescopic member is concentric with the center of the housing.

[0014] In some embodiments, the arc-shaped telescopic member has a central angle of less than or equal to 180° in its extended state.

[0015] In some embodiments, the fixing part includes: a movable seat, which is movably disposed in the first groove;

[0016] The shape of the movable seat matches the shape of the first groove, which is a dovetail groove structure.

[0017] In some embodiments, the movable base has a second fixing hole, and the fixing part further includes a second locking member, which is disposed in the second fixing hole and abuts against the first groove.

[0018] In some embodiments, the first groove is located above the stator, or the first groove extends to the middle or bottom of the stator.

[0019] In some embodiments, the refrigeration device includes a refrigeration device body and a compressor as described in the foregoing embodiments, wherein the compressor is disposed within the refrigeration device body.

[0020] The compressor and refrigeration equipment provided in this disclosure can achieve the following technical effects:

[0021] The stator is rotatably mounted within the housing via a rotating assembly, facilitating adjustment of its angle within the housing to change the root angle of the stator leads. Simultaneously, the outer wall of the stator does not directly contact the inner wall of the housing, reducing the contact area and minimizing thermal deformation, thus improving motor efficiency and noise. Furthermore, the rotating assembly also serves a positioning function, ensuring the coaxiality of the stator and rotor. Building upon this, the inner wall of the housing has a first groove along its vertical direction, and a fixing part of a limiting device is installed within the first groove. A limiting part is connected to the fixing part, allowing it to move synchronously with the fixing part. The outer wall of the stator has one or more second grooves circumferentially arranged along its vertical direction. When the stator rotates to a set position, the fixing part of the limiting device moves, causing the limiting part to enter the second groove and fixing the limiting part to secure the stator. This allows the stator inside the compressor to be adjusted to a set angle and then fixed, improving the versatility of the stator assembly tooling, reducing the time spent switching stator assembly tooling, saving the cost of stator assembly tooling, and thus improving production efficiency.

[0038] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein.

[0040] In this disclosure, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of the embodiments of this disclosure and their implementations, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to require them to be constructed and operated in a specific orientation. Furthermore, some of the aforementioned terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this disclosure according to the specific circumstances.

[0041] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0042] Unless otherwise stated, the term "multiple" means two or more.

[0043] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] refer to Figure 1As shown, the rotary compressor includes a compressor housing 1a and a compressor cover 1e disposed on the upper part of the compressor housing 1a. A distributor 1h is also connected to the compressor housing 1a. Inside the compressor housing 1a, there is a fixedly connected motor stator 1b and a motor rotor 1c inserted into the motor stator 1b and rotatable relative to the motor stator 1b. A terminal 1I is provided on the motor stator 1b, and a cover terminal 1f and a cover exhaust pipe 1g are provided on the compressor cover 1e. One end of the motor stator lead 1d (i.e., the motor wire) is connected to the terminal 1I, and the other end of the motor stator lead 1d is electrically connected to the power supply line of other equipment through the cover terminal 1f.

[0047] Because heat fitting is used for assembly, the dimensional and positional tolerances of the components are less critical, which reduces the processing cost to some extent. Therefore, heat fitting is often used to fix the motor stator 1b in the compressor housing 1a. Furthermore, this method effectively ensures the coaxiality of the compressor housing 1a and the motor stator 1b, thereby ensuring the coaxiality of the motor stator 1b and the motor rotor 1c. Specifically, the compressor housing 1a is first heated, and its inner diameter increases as it expands. The heated compressor housing 1a is then fitted around the motor stator 1b. After the compressor housing 1a cools and contracts, its inner diameter decreases, allowing the inner wall of the compressor housing 1a to be assembled with the outer wall of the motor stator 1b using an interference fit. However, in this assembly method, because the contact area between the outer wall of the motor stator 1b and the inner wall of the compressor housing 1a is large, uneven cooling rates at different locations on the compressor housing 1a can lead to varying deformations in the motor stator 1b, affecting motor efficiency and noise.

[0048] On the other hand, because the wiring angles of the power cord and the top cover terminal 1f differ between different devices, various top cover assembly angles will occur when the same model of compressor is used in different devices. This top cover assembly angle is the angle between the axial line of the top cover terminal 1f, the axis of the distributor 1h, and the axis of the compressor housing 1a, forming a plane. If the angle of the motor stator 1b cannot be adjusted, the angle deviation between the motor terminal 1I and the top cover terminal 1f may be large, requiring a longer motor stator lead 1d. However, an excessively long motor stator lead 1d may affect the normal operation of the compressor. For example, the motor stator lead 1d may contact the inner wall of the compressor housing 1a, causing noise; contact the upper end of the motor rotor 1c, affecting motor efficiency; or block the inlet of the top cover exhaust pipe 1g, affecting the refrigerant nozzle's ability to add refrigerant oil to the compressor. Therefore, the angle between terminal 1I and the top cover terminal 1f is within a fixed range.

[0049] In order to enable the terminal 1I of the motor stator 1b to change with the assembly angle of the compressor cover 1e, a corresponding stator assembly fixture is configured for each stator heat fitting angle during compressor production assembly. That is, multiple sets of stator assembly fixtures are configured. This means that when producing and assembling compressors of the same specification and model, it is necessary to frequently switch the corresponding stator assembly fixtures, which not only increases the corresponding assembly cost and time cost, but also affects production efficiency.

[0050] Combination Figures 2 to 4 As shown, this embodiment of the present disclosure provides a compressor, including a housing 10, a stator 20, and a limiting device 40. The housing 10 has a first groove 11 arranged vertically on its inner sidewall; the stator 20 is rotatably disposed within the housing 10 via a rotating assembly 30, wherein one or more second grooves 21 arranged vertically are arranged circumferentially on the outer sidewall of the stator 20; the limiting device 40 includes a fixing part 41 movably disposed within the first groove 11 and a limiting part 42 connected to the fixing part 41. The fixing part 41 and the limiting part 42 move synchronously. When the stator 20 rotates to a set position, moving the fixing part 41 of the limiting device 40 causes the limiting part 42 to enter the second groove 21, and fixing the fixing part 41 causes the limiting part 42 to fix the stator 20.

[0051] In the compressor provided in this embodiment, the stator 20 is rotatably mounted within the housing 10 via the rotating assembly 30, facilitating adjustment of the angle at which the stator 20 is positioned within the housing 10 to change the root angle (i.e., the terminal) of the stator leads. Simultaneously, the outer wall of the stator 20 does not directly contact the inner wall of the housing 10, reducing the contact area between the stator 20 and the housing 10. This reduces deformation of the stator 20 due to heat, thereby improving motor efficiency and noise. Furthermore, the rotating assembly 30 also serves a positioning function, ensuring the coaxiality of the stator and rotor. Based on this, a first groove 11 is provided on the inner sidewall of the housing 10 along its vertical direction, and a fixing part 41 of a limiting device 40 is provided in the first groove 11. A limiting part 42 is connected to the fixing part 41, and the limiting part 42 can move synchronously with the fixing part 41. One or more second grooves 21 are provided circumferentially on the outer sidewall of the stator 20 along its vertical direction. When the stator 20 rotates to a set position, the fixing part 41 of the limiting device 40 is moved so that the limiting part 42 enters into the second groove 21, and the fixing part 41 is fixed so that the limiting part 42 fixes the stator 20. In this way, the stator in the compressor can be adjusted to a set angle and then fixed, improving the versatility of the stator assembly tooling, reducing the time for changing stator assembly tooling, saving the cost of stator assembly tooling, and thus improving production efficiency.

[0052] In this embodiment, in order to enable the stator 20 to rotate and adjust within the housing 10, a rotating assembly 30 is provided between the outer wall of the stator 20 and the inner wall of the housing 10. This assembly is combined with... Figure 5 At point D and Figure 6 As shown, the rotating assembly 30 can be disposed on the outer side wall of the stator 20 or the inner side wall of the housing 10.

[0053] Taking the rotating component 30 embedded in the outer wall of the stator 20 as an example, one or more annular grooves 22 are formed on the outer wall of the stator 20. The rotating component 30 is disposed in the annular groove 22, and a portion of the rotating component 30 protrudes from the annular groove 22 to abut against the inner wall of the housing 10. Optionally, the rotating component 30 can be rolled or slidably connected to the annular groove 22, and the rotating component 30 is fixedly connected to the inner wall of the housing 10. Optionally, the rotating component 30 can be rolled or slidably connected to the inner wall of the housing 10, and the rotating component 30 is fixedly connected to the annular groove 22. Optionally, the rotating component 30 itself has a rolling or sliding structure and is fixedly connected to the inner wall of the housing 10 and the annular groove 22, respectively. Optionally, the rotating component 30 includes at least one of ball bearings, needle rollers, and bearings.

[0054] Optionally, in some embodiments, when the rotating assembly 30 uses ball bearings and / or needle rollers, a plurality of ball bearings and / or needle rollers are arranged in the annular groove 22. The length of the ball bearings and / or needle rollers after they are in contact is greater than half the circumference of the annular groove 22, thus ensuring that both the left and right sides of the stator 20 have ball bearings and / or needle rollers that are interference-fitted with the inner wall of the housing 10.

[0055] Optionally, in some embodiments, when the stator 20 is relatively high, to avoid contact between the stator 20 and the housing 10, multiple annular grooves 22 can be provided in the vertical direction. Here, taking the annular groove 22 with several balls arranged in a ring as an example, and the balls are evenly distributed in a circular cross-section, the vertical ball spacing needs to meet the following conditions:

[0056] ΔS≤h / n;

[0057] Where ΔS is the vertical ball spacing, h is the stator height 20, and n is the number of balls on each cross-sectional circle, which is at least 3.

[0058] In this embodiment of the disclosure, when the rotating assembly 30 uses a bearing, it can be a single bearing structure or two semi-circular bearing structures. Using two semi-circular bearing structures facilitates the installation of the bearing in the annular groove 22. Optionally, the inner ring portion of the bearing is located in the annular groove 22, and the outer ring portion of the bearing is interference-fitted with the inner wall of the housing 10.

[0059] In the above embodiment, an inner wall groove that cooperates with the rotating component 30 can also be provided on the inner side wall of the housing 10. The inner wall groove cooperates with the rotating component 30 and the annular groove 22. Without the action of external force, the stator 20 will not move axially, thereby playing a positioning role and ensuring the coaxiality of the stator and the rotor.

[0060] In this embodiment of the disclosure, combined with Figure 5 As shown at point E, the inner wall of the housing 10 is interference-fitted with the outer wall of the stator 20, and the inner diameter of the housing 10 is slightly larger than the outer diameter of the stator 20. To further ensure the axial stability of the stator 20, the housing 10 is provided with an overlapping portion 12 at the bottom of the stator 20, and the bottom of the stator 20 abuts against the overlapping portion 12. The overlapping portion 12 provides axial limiting and support for the stator 20 to improve the axial stability of the stator 20.

[0061] In this embodiment of the disclosure, combined with Figure 5 As shown, the overlapping portion 12 can be achieved by enlarging the upper part of the housing 10 corresponding to the stator 20, so that the upper and lower parts of the housing 10 form two housing segments with different inner diameters. A stepped structure is formed between the two housing segments, which can axially limit and support the stator 20. This stepped structure is the overlapping portion 12. Here, by enlarging the hole, the inner diameter of the upper part of the housing 10 is increased, while the inner diameter of the lower part of the housing 10 remains unchanged. In this way, under the action of the overlapping portion 12, the axial positioning depth of the stator 20 can also be determined.

[0062] After the upper housing section is enlarged, a gap δ is formed between the outer wall of the stator 20 and the inner wall of the housing section. The value of the gap δ ranges from 0 to 1.2 mm. Here, the value of the gap δ can be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1 mm, and is not limited to any particular value, as long as it ensures that the outer wall of the stator 20 does not contact the inner wall of the housing 10.

[0063] In the above embodiments, combined with Figure 5 As shown at point F, the outer edge of the upper cover 60 is also provided with a stop 61 that overlaps with the opening of the housing 10. In this way, after the housing 10 is enlarged, the stop 61 of the upper cover 60 can overlap the upper end of the housing 10 without affecting the subsequent welding of the upper cover 60 and the housing 10.

[0064] In this embodiment, the rotating assembly 30 creates a gap between the outer wall of the stator 20 and the inner wall of the housing 10. This reduces the contact area between the stator 20 and the housing 10, decreases the deformation of the stator 20 due to heat, and reduces compressor noise during operation. The inner wall of the housing 10 and the outer wall of the rotating assembly 30 are press-fitted together via a thermal fitting, allowing the stator 20 to rotate relative to the housing 10 under external force. To limit the rotation of the stator 20, a limiting device 40 is provided on the inner wall of the housing 10. Adjusting the angle of the stator 20 allows the limiting device 40 to restrict its rotation within the housing 10.

[0065] Optionally, when the stator 20 rotates to a preset position, the terminal on the side of the stator 20 is connected to the connecting post on the upper cover 60 through the stator lead wire, and then the stator 20 is fixed by the limiting device 40 to prevent the stator 20 from rotating inside the housing 10 during the operation of the compressor.

[0066] In this embodiment, the limiting device 40 can limit and fix the stator 20 to any position it rotates to. Therefore, a first groove 11 is provided on the inner wall of the housing 10 along its vertical direction; one or more second grooves 21 are provided circumferentially on the outer wall of the stator 20 along their vertical direction. The limiting device 40 includes a fixing part 41 movably disposed within the first groove 11 and a limiting part 42 connected to the fixing part 41. The fixing part 41 and the limiting part 42 move synchronously. Thus, when the stator 20 rotates to a set position, the fixing part 41 of the limiting device 40 is moved to allow the limiting part 42 to enter the second groove 21, and the fixing part 41 is fixed to fix the limiting part 42 to fix the stator 20. Here, the fixing part 41 and the limiting part 42 are connected by an arc-shaped member of a set length. The curvature of this arc-shaped member is adapted to the inner wall of the housing 10. Therefore, the limiting device 40 can limit and fix the stator 20 to any position it rotates to.

[0067] In some alternative embodiments, the stator 20 can be fixed to the inner wall of the housing 10 by welding. Here, the fixing part 41 of the limiting device 40 is solder. After the angle of the stator 20 is adjusted, the fixing part 41 is welded to the inner wall of the housing 10 by spot welding.

[0068] In some alternative embodiments, the second groove 21 can be an oil return groove on the outer wall of the stator 20, so that the structure of the stator does not need to be modified and the existing structure of the stator 20 can be fully utilized.

[0069] Combination Figure 2 As shown, in some embodiments, the fixing part 41 is fixedly connected to the limiting part 42 by the arc-shaped telescopic member 50.

[0070] In this embodiment, the limiting device 40 includes a fixing part 41, an arc-shaped telescopic member 50 fixedly connected to the fixing part 41, and a limiting part 42 fixedly connected to the end of the arc-shaped telescopic member 50. Thus, the distance between the fixing part 41 and the limiting part 42 can be adjusted by the arc-shaped telescopic member 50. During the assembly of the stator 20 and the housing 10, the stator 20 can be rotated by the rotating assembly 30. When the stator 20 moves to a set position, the limiting device 40 is installed on the inner wall of the housing 10. The fixing part 41 moves vertically within the first groove 11, and the limiting part 42 also moves vertically. Here, based on the position of the first groove 11, the nearest second groove 21 is found. The arc-shaped telescopic member 50 extends or shortens according to the position of the second groove 21, thereby allowing the limiting part 42 to be vertically inserted into the second groove 21 to fix the stator 20.

[0071] Combination Figure 2 As shown at point A, in some embodiments, the arc-shaped telescopic member 50 includes an arc-shaped inner core 51 and an arc-shaped outer shell 52. The arc-shaped inner core 51 is fixedly connected to the fixing part 41 or the limiting part 42; the arc-shaped outer shell 52 is sleeved on the arc-shaped inner core 51 and is fixedly connected to the limiting part 42 or the fixing part 41.

[0072] In this embodiment, to enable the arc-shaped telescopic member 50 to perform its telescopic function, the arc-shaped telescopic member 50 includes an arc-shaped outer shell 52 and an arc-shaped inner core 51 that extends into and slides within the arc-shaped outer shell 52. Here, the arc-shaped inner core 51 can be an arc-shaped rod or an arc-shaped plate, and the corresponding arc-shaped outer shell 52 can be an arc-shaped sleeve or an arc-shaped housing. Wherein, when the arc-shaped inner core 51 is connected to the fixing part 41, the arc-shaped outer shell 52 is connected to the limiting part 42. Optionally, when the arc-shaped inner core 51 is connected to the limiting part 42, the arc-shaped outer shell 52 is connected to the fixing part 41.

[0073] Optionally, in some embodiments, the first groove 11 is located above the stator 20. Here, when the arc-shaped inner core 51 is an arc-shaped rod and the arc-shaped outer shell 52 is an arc-shaped sleeve, the fixing part 41 is located inside the first groove 11, which is also above the stator 20. In order to facilitate the entry of the limiting part 42 into the second groove 21, the limiting part 42 extends vertically downward from the end of the arc-shaped inner core 51. In this way, it is not only convenient to move or fix the fixing part 41 in the first groove 11, but also convenient to control the vertical limiting depth of the limiting part 42.

[0074] When the arc-shaped inner core 51 adopts an arc-shaped plate and the arc-shaped outer shell 52 adopts an arc-shaped sleeve, the fixing part 41 can be set at the upper part of one side of the arc-shaped outer shell 52, and the limiting part 42 can be set at the lower part of one side of the arc-shaped inner core 51. In this way, there is a height difference between the limiting part 42 and the fixing part 41, which still makes it convenient to move or fix the fixing part 41 in the first groove 11, and also makes it easy to control the vertical limiting depth of the limiting part 42.

[0075] Optionally, in some embodiments, the first groove 11 extends to the middle or bottom of the stator 20. In cases where multiple positioning is required, the fixing part 41 can also serve to fix the stator 20 by moving to the middle or bottom of the stator 20 through the first groove 11.

[0076] In this embodiment of the disclosure, combined with Figure 3 As shown at point B, the limiting part 42 can be a locking block structure. To ensure smooth entry of the locking block structure into the second groove, the side of the end face of the locking block structure that contacts the second groove 21 is also designed with rounded corners. This allows the rounded corners of the locking block structure to easily enter the second groove 21, preventing issues such as difficulty in entry or locking.

[0077] In some embodiments, the center of the arc-shaped telescopic member 50 is concentric with the center of the housing 10. Since the arc-shaped telescopic member 50 extends and retracts on the inner sidewall of the housing 10, in order to avoid the arc-shaped telescopic member 50 obstructing the stator 20 or other components, the center of the arc-shaped telescopic member 50 is concentric with the center of the housing 10, and the arc-shaped telescopic member 50 is in close contact with the inner sidewall of the housing 10.

[0078] In some embodiments, to facilitate the fixing of the stator 20, the arc-shaped telescopic member 50 has a central angle of less than or equal to 180° in its extended state. Since the arc-shaped telescopic member 50 extends and retracts along the inner wall of the housing 10, the limiting part 42 can enter the second groove 21 at different positions by changing the length of the arc-shaped telescopic member 50. On the other hand, since the angle of the plane is 360 degrees, if the central angle of the arc-shaped telescopic member 50 is 180° in its extended state, the limiting part 42 can enter the second groove 21 from the first side direction if it cannot enter from the first side direction. Therefore, it can be ensured that regardless of the angle to which the stator 20 rotates, the limiting part 42 can enter the second groove 21 by changing the aspect of the arc-shaped telescopic member 50.

[0079] Optionally, since the distribution of the second groove 21 is different, the center angle of the arc-shaped telescopic member 50 in the extended state can be adapted to change. Here, the angle of the center angle of the arc-shaped telescopic member 50 in the extended state can be 30°, 60°, 90°, 120°, 150° or 180°, and is not limited here.

[0080] Combination Figure 2 As shown at point A, in some embodiments, a first fixing hole 53 is provided on the outer side of the arc-shaped outer shell 52, and the arc-shaped telescopic member 50 further includes: a first locking member 54, which is disposed in the first fixing hole 53 and abuts against the arc-shaped inner core 51.

[0081] In this embodiment, the arc-shaped outer shell 52 and the arc-shaped inner core 51 are fixed by the first locking member 54 to prevent the arc-shaped outer shell 52 and the arc-shaped inner core 51 from sliding after the stator 20 is fixed. The first fixing hole 53 is a threaded through hole, and the first locking member 54 is a screw. Optionally, when the arc-shaped inner core 51 is an arc-shaped rod and the arc-shaped outer shell 52 is an arc-shaped sleeve, multiple first fixing holes 53 arranged side-by-side can be provided in the arc direction of the arc surface of the arc-shaped outer shell 52, and the first locking member 54 abuts against the arc-shaped inner core 51 through one of the first fixing holes 53. Optionally, when the arc-shaped inner core 51 is an arc-shaped plate and the arc-shaped outer shell 52 is an arc-shaped sleeve, arrayed first fixing holes 53 can be provided in both the arc direction and the vertical direction of the arc-shaped outer shell 52, and the first locking member 54 abuts against the arc-shaped inner core 51 through one of the first fixing holes 53.

[0082] Combination Figure 4 As shown at point C, in some embodiments, the fixing part 41 includes: a movable seat 411, which is movably disposed in the first groove 11; wherein the shape of the movable seat 411 matches the shape of the first groove 11, and the first groove 11 has a dovetail groove structure.

[0083] In this embodiment, to facilitate the movement of the fixing part 41, a movable seat 411 is provided in the first groove 11. Here, the movable seat 411 can slide or roll within the first groove 11, which is not limited here. To prevent the movable seat 411 from detaching from the first groove 11, the first groove 11 has a dovetail groove structure, and the shape of the movable seat 411 matches the shape of the first groove 11, so that the movable seat 411 is engaged within the first groove 11 and moves vertically.

[0084] Combination Figure 4 As shown at point C, in some embodiments, the movable seat 411 is provided with a second fixing hole 412, and the fixing part 41 further includes a second locking member 413, which is disposed in the second fixing hole 412 and abuts against the first groove 11.

[0085] In this embodiment, the movable seat 411 is fixed to the first groove 11 by a second locking member 413. Here, a second fixing hole 412 is provided on the movable seat 411, wherein the second fixing hole 412 is also a threaded through hole, and the second locking member 413 is also a screw. The second locking member 413 passes through the through hole, and its tail end abuts against the first groove 11, thus completing the fixing of the movable seat 411.

[0086] In conjunction with the above embodiments, during the actual assembly process, before the stator 20 is installed into the housing 10, the limiting device 40 is not pre-installed onto the housing 10 to ensure that the housing 10 can be heat-fitted onto the stator 20. After the stator 20 is installed into the housing 10, the stator 20 is rotated relative to the housing 10 to adjust to the set position. The fixing part 41 is inserted into the first groove 11 from the upper end of the housing 10. The length of the arc-shaped telescopic member 50 is adjusted so that the limiting part 42 is aligned with a nearby second groove 21. Then, the fixing part 41 is slid downward to insert the limiting part 42 into the second groove 21. Then, the first locking member 54 and the second locking member 413 are locked to fix the length of the arc-shaped telescopic member 50 and the vertical position of the fixing part 41, thereby fixing the circumferential position of the stator 20 and the housing 10.

[0087] In conjunction with the above embodiments, when it is necessary to readjust the angle of the stator lead wires, for example, when recycling a stock compressor of the same specification and model, the assembly angle of the upper cover terminal of the compressor cannot be adapted to the equipment. The upper cover of the stock compressor is removed from the housing 10 and the assembly angle of the upper cover terminal is adjusted. The first locking member 54 and the second locking member 413 are loosened and the limiting part 42 is disengaged from the second groove 21. Then, the stator 20 is adjusted in the above manner so that the terminal on the stator side and the terminal on the upper cover are within the set angle range.

[0088] This disclosure also provides a refrigeration device, including a compressor as described in the foregoing embodiments, wherein the refrigeration device includes an air conditioner, refrigerator, freezer, wine cabinet, etc.

[0089] In this embodiment, the refrigeration equipment includes the compressor described above. Referring to the above embodiments, it at least has the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
