Description
TECHNICAL FIELD
[0001] The utility model relates to a device for refrigeration refrigerator or refrigerator. BACKGROUND
[0002] At present, the refrigeration pipeline of the refrigerator is mostly thin-walled pipe, such as copper pipe, aluminum pipe and iron pipe. The strength of the connection between the two kinds of pipes is very poor, and the refrigeration pipeline is easy to crack, resulting in leakage of refrigerant and loss of refrigeration function of the whole machine. Some factories currently use heat shrink sleeves to strengthen. Since the heat shrink sleeve material is very soft and has limited strength, it is time-consuming and labor-intensive, and cannot fundamentally solve the problem, resulting in a high proportion of internal leakage after the workers operate the pipeline.

[0003] The utility model aims to provide a fastening device for the refrigeration pipeline of a refrigerator or refrigerator, which has the characteristics of convenient use and high strength.
[0004] The utility model is implemented in the following manner: a fastening device for the refrigeration pipeline of a refrigerator or refrigerator, characterized in that it comprises an optimal arc-shaped ring body, a female connecting seat and a male connecting piece,
[0005] The female connecting seat and the male connecting seat are inserted.
[0006] Preferably, one side of the female connecting seat is connected to one end of the optimal arc-shaped ring body and is provided with a check connecting cavity,
[0007] The male connecting piece comprises a seat plate and a check connecting plate provided on the seat plate,
[0008] The check connecting plate is inserted into the check connecting cavity, and the seat plate and the female connecting seat are attached.
[0009] Preferably, check ratchet grooves are provided on the two side wall plates of the check connecting cavity.
[0010] Check ratchets are provided on the check connecting plate, and the check ratchets and the check ratchet grooves are embedded.
[0011] Preferably, a triangular cavity is provided at the closed end of the check connecting cavity.
[0012] A triangular head is provided at the end of the check connecting plate.
[0013] Preferably, wrenches are respectively provided on the seat plates of the female connecting seat and the male connecting piece.
[0014] Preferably, the optimal arc-shaped ring body, the female connecting seat and the male connecting piece are integrally formed by using an extrusion process of plastic material.
[0015] The utility model relates to a fastening device of refrigerator or freezer refrigeration pipeline, and the optimal arc-shaped ring body has certain bendable performance, is convenient to assemble and wraps the pipeline connection when using, effectively protects the connection. BRIEF DESCRIPTION OF DRAWINGS
[0016] Figure 1 It is the front view of the utility model.
[0017] Figure 2 It is the perspective view of the utility model. DETAILED DESCRIPTION
[0018] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as the limitation of the utility model.
[0019] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting" and "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0020] As Figure 1 The utility model relates to a fastening device of refrigerator or freezer refrigeration pipeline, and the optimal arc-shaped ring body has certain bendable performance, is convenient to assemble and wraps the pipeline connection when using, effectively protects the connection.
[0021] The sub-connector 3 and the female connector seat 2 are inserted.
[0022] One side of the female connector seat 2 is connected with one end of the optimal arc-shaped ring body 1 and is provided with a check connection cavity 21,
[0023] The sub-connector 3 includes a seat plate 31 and a check connection plate 32 provided on the seat plate 31,
[0024] The check connection plate 32 is inserted into the check connection cavity 21, and the seat plate 31 and the suspended end of the female connector seat 2 are attached.
[0025] As a further improvement of the utility model: the two side wall plates of the check connection cavity 21 are provided with check ratchet grooves 211;
[0026] The check connection plate 32 is provided with check ratchet teeth 321; the check ratchet teeth 321 and the check ratchet grooves 211 are groove fitted.
[0027] As further improvement of the utility model: the closed end of the check connection cavity 21 is equipped with a triangular cavity 212;
[0028] The end of the check connecting plate 32 is equipped with a triangular head 322, and the triangular head 322 and the triangular cavity 212 are embedded.
