Abstract
Description
Technical Field
[0001] The utility model relates to a cross-tube protective sleeve for an evaporator. Background Art
[0002] Conventional household air conditioner indoor units all use copper tubes + fins as heat exchange mechanisms. However, during transportation, the copper tubes may collide with the assembly base, causing the copper tubes to be dented and affecting the performance of the entire unit. In order to protect the cross-tubes close to the assembly base, it is usually necessary to install cross-tube covers on the cross-tubes. The conventional cross-tubes of general double-row evaporators are straight cross-tubes and oblique cross-tubes. The sizes of the two cross-tubes are different, so different sizes of cross-tube covers are required. However, since the sizes of the cross-tubes are relatively close, the size of the cross-tube covers cannot be quickly judged by the naked eye during installation, and it is easy to use the wrong ones when selecting them, which will greatly reduce production efficiency. Utility Model Content
[0003] In view of the above problems, the present invention provides a cross-tube jacket for an evaporator, which effectively solves the problems pointed out in the background technology.
[0004] The technical solution adopted in this utility model is:
[0005] A cross-tube protective sleeve for an evaporator includes an annular column, one end of the annular column is a large ring fitting opening, and the other end is a small ring fitting opening. A notch is opened on the side of the annular column and passes through both ends of the annular column. An inwardly protruding triangular limit buckle is provided on the inner side of the annular column at the connection between the large ring fitting opening and the small ring fitting opening. The triangular limit buckle plays a bidirectional guiding role when assembling and snapping in.
[0006] Preferably, the annular column and the triangular limiting buckle are integrally formed.
[0007] The one-piece structure can ensure the overall strength while simplifying the production process and reducing production costs.
[0008] Preferably, the annular column is flat in shape, and the left and right sides of the large ring fitting opening are beveled toward the middle of the annular column.
[0009] Since the large ring mating opening is large in size, in order to avoid the large ring mating opening occupying a large space when facing outward, a bevel angle can be set to avoid other components.
[0010] Preferably, the triangular limiting buckle is located close to the notch.
[0011] The triangular limit buckle is arranged near the notch, and can produce a small deformation when the cross-tube cover is inserted into the cross-tube, thereby ensuring that the cross-tube cover can be inserted quickly and easily.
[0012] The utility model provides a large ring fitting opening and a small ring fitting opening at both ends of the annular column, so that the two ends of the cross-tube sheath can be used for straight cross-tubes and oblique cross-tubes respectively, thereby avoiding mistakes during assembly and quickly selecting the large ring fitting opening or the small ring fitting opening for use, thereby greatly improving production efficiency.

[0016] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.
[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0018] In addition, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.
[0020] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0022] The present invention will be described in further detail below through specific embodiments with reference to the accompanying drawings.
[0023] like Figure 1 As shown, a cross-tube sleeve for an evaporator includes an annular column 1, one end of the annular column 1 is a large ring fitting opening 2, and the other end is a small ring fitting opening 3. The side of the annular column 1 is provided with a notch 4 that passes through both ends of the annular column 1, and the inner side of the annular column 1 is provided with an inwardly protruding triangular limit buckle 5 at the connection between the large ring fitting opening 2 and the small ring fitting opening 3.
[0024] The annular column 1 and the triangular limiting buckle 5 are integrally formed.
[0025] The annular column 1 is flat in shape, and the left and right sides of the large ring fitting opening 2 are beveled angles 6 inclined toward the middle of the annular column 1 .
[0026] The triangular limiting buckle 5 is located near the notch 4 .
[0027] like Figure 2-3 As shown, when protecting the straight span pipe and the oblique span pipe closest to the assembly base, since the width of the oblique span pipe is smaller and the width of the straight span pipe is larger, the large ring matching port 2 of the sampling utility model is used to protect the straight span pipe, and the small ring matching port 3 is used to protect the oblique span pipe. The working principle of the assembly card is:
[0028] To protect the straight span pipe: the large ring matching port 2 of the utility model is directed toward the straight span pipe and inserted. When inserted, the annular column 1 is slightly deformed under the guidance of the triangular limit buckle 5. After the insertion is completed, the shape of the annular column 1 is restored, and the assembly of the span pipe sheath is completed at this time;
[0029] To protect the diagonal cross-tube: point the small ring fitting port 3 of the utility model toward the diagonal cross-tube and snap it in. When snapping it in, under the guidance of the triangular limit buckle 5, the annular column 1 produces a small deformation. After the snapping is completed, the shape of the annular column 1 is restored, and the assembly of the cross-tube sheath is completed.
[0030] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and is subject to numerous variations. All variations that can be directly derived or conceived by a person of ordinary skill in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
