Description

Technical Field

[0001] The utility model relates to a stator screw wrap, in particular to a stator screw wrap used for a compressor motor. Background Art

[0002] The stator screw ring in the motor can protect the stator screws and fixing screws, and ensure the safety of the stable operation of the motor. The general stator screw ring structure is a metal sleeve structure with a hole in the middle. When it is matched with the motor, due to the complexity of the external structure of the motor, in order to make the ring structure more stable, it is generally connected by welding. Since the outer part of the ring is a circular structure, there are many gaps between it and the motor, so there are many welding points, which increases the local weight of the motor and affects the performance of the motor. Summary of the Invention

[0003] In order to overcome the above-mentioned deficiencies, the present invention provides a stator screw wrap, which has better fit with the motor, reduces the overall weight, and ensures a stable structure.

[0004] To achieve this purpose, the structure adopted by the utility model is: the stator screw ring includes a body, which is a metal strip structure with a screw hole in the center, a base provided at the bottom edge of the body, and a protruding rectangular block structure. Sides are symmetrically provided on both sides of the body above the base, and a boss is provided in the center, with two grooves formed between the side and the boss.

[0005] A missing block is provided on the top of the main body, and the missing block is located above the boss.

[0006] The side cross section is wedge-shaped, with a wider end connected to the body, and two side edges forming a notch with a narrow center and wide sides.

[0007] The beneficial effects are as follows: the structural design of the utility model is reasonable and ingenious, the grooves formed by the side and the boss can make the body fit more closely with the motor, reduce the gap, and thus reduce the welding points, the missing block on the top is used to avoid the protruding part of the motor, and the bottom base has a certain protection and support function, the overall structure is lightened, and after being connected to the motor, the stability of the stator screws is guaranteed while reducing the influence of the dead weight on the running performance of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0009] Figure 1 It is a three-dimensional structural diagram of the utility model;

[0010] Figure 2 It is a top view structural diagram of the present utility model. DETAILED DESCRIPTION

[0011] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0012] In the description of the utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; 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 internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0014] like Figure 1 、 Figure 2 The stator screw ring shown includes a body 1, which is a metal strip structure. It is formed by pressing and sintering copper, carbon, iron and other powders in a certain proportion. A screw hole 2 is provided in the center. A base 3 is provided at the bottom edge of the body 1. The base 3 is a protruding rectangular block structure. Sides 4 are symmetrically provided on both sides of the body 1 above the base 3. A boss 5 is provided in the center. Two grooves 6 are formed between the side 4 and the boss 5.

[0015] The groove 6 formed by the side 4 and the boss 5 can make the main body 1 fit more closely with the motor, reduce the gap, and thus reduce the number of welding points. The bottom base 3 has a certain protection and support function, and the weight of the overall structure is reduced. After being connected to the motor, the stability of the stator screws is guaranteed while reducing the influence of the dead weight on the motor's operating performance.

[0016] The main body 1 has a side with one side being inwardly concave and the other side being arc-shaped, and the entire edge is rounded.

[0017] A missing block 6 is provided at the top of the body 1, above the boss 5. The missing block 6 is 1 / 3 to 1 / 2 of the overall length and extends from the outside to the screw hole 2, leaving the screw hole 2 open in this section. The missing block 6 avoids the protruding portion of the motor and allows the body 1 to have a certain reduced space at this location, making the body more closely fit the motor surface while further reducing the overall weight.

[0018] The side edges 4 are wedge-shaped in cross-section, with the wider end connected to the main body 1. The two sides form a notch that is narrow in the center and wide at the sides. The notch increases the contact area between the main body 1 and the motor when in contact. The outwardly expanding notch also provides support, increasing overall strength and rigidity, and reducing the number of solder joints required for motor connection.

[0019] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
