[0018] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] As Figures 1-4 shown, a fixing device includes a fixing column 10 and a positioning assembly. An annular notch 11 is provided on the fixing column. The positioning assembly includes a pressing plate 40, a positioning plate 20, and an elastic transition part 30 for connecting the pressing plate and the positioning plate. An opening 44 is provided on the pressing plate. The opening penetrates through the edge of the end of the pressing plate away from the elastic transition part. The positioning plate 20 is horizontally arranged and is provided with a positioning hole 21. A blocking plate 12 is fixedly provided at the bottom of the fixing column. The positioning assembly tilts the positioning plate 20 upward, so that the inner walls on both sides of the opening 44 are in tight contact with the bottom surface of the annular notch. After releasing the positioning plate, the upper part of the fixing column passes through the positioning hole, and a positioning area is formed between the pressing plate 40 and the blocking plate 12.

[0020] The installation part 1 around the refrigerator compressor has installation holes. In the prior art, when installing a refrigerator compressor, most commonly, screws and nuts are used for fixation. Using screws for fixation has good reliability but is cumbersome in operation, and it is difficult to operate the nuts near the inner side of the compressor compartment.

[0021] When fixing the installation part 1 of the refrigerator compressor in the present invention, first, the blocking plate 12 is fixedly connected to the refrigerator body, and the fixing column 10 passes through the installation hole of the refrigerator compressor, and a positioning component is used to fixedly install the refrigerator compressor; the fixing column 10 is snapped into the opening 44, and the inner walls on both sides of the opening are clamped tightly with the bottom surface of the annular notch 11. Since the elastic transition part 30 has elasticity, the positioning plate 20 can be forcefully tilted upwards. Then, the positioning component is continuously moved so that the upper part of the fixing column 10 is approximately aligned with the positioning hole 21 on the positioning plate. The positioning plate is released, and the upper part of the fixing column passes through the positioning hole 21 to complete the positioning.

[0022] The annular notch restricts the vertical movement of the pressing plate, and the positioning hole restricts the horizontal movement of the positioning plate, thereby realizing the movement of the entire positioning component in the vertical and horizontal directions; the pressing plate 40 presses tightly against the upper surface of the installation part 1, and the lower surface of the installation part 1 is in tight contact with the blocking plate 12, thus completing the positioning of the refrigerator compressor.

[0023] When disassembling the positioning component from the fixing column, only need to forcefully tilt the positioning plate upwards so that the upper part of the fixing column leaves the positioning hole, and push the positioning component to make the fixing column disengage from the opening to complete the disassembly.

[0024] The fixing device can conveniently clamp the installation part of the refrigerator compressor on the fixing column and press it tightly, with firm installation and convenient disassembly during maintenance, reducing the time cost during installation and maintenance.

[0025] As Figures 1-4 shown, the fixing device further includes a pressing plate 50. One end of the pressing plate is fixedly connected to the end of the positioning plate 20 away from the elastic transition part. The pressing plate tilts upwards and forms an obtuse angle with the positioning plate; when forcefully tilting the positioning plate, the force of a person's finger can act on the pressing plate 50, avoiding the injury to the finger caused by the edge of the positioning plate when the force is too large, and improving the safety during operation.

[0026] As Figure 4 shown, the cross-sectional shape of the elastic transition part 30 is an arc. The elastic transition part is sequentially divided into an upper transition part 31, a middle transition part 32, and a lower transition part 33 from top to bottom. One end of the lower transition part 33 close to the pressing plate is fixedly connected to one end of the pressing plate 40. The pressing plate 40 is tangent to the lower transition part at their connection. One end of the upper transition part 31 close to the positioning plate is fixedly connected to one end of the positioning plate 20. The upper transition part is higher than the upper surface of the positioning plate.

[0027] As Figure 5 shown, on the cross-section of the positioning component, the connection point between the pressing plate and the elastic transition part is point A, and the point on the inner wall of the positioning hole that is farthest from point A is point B. Under normal circumstances, the distance between point A and point B is AB, and the length of AB does not change. During the process of the positioning plate tilting up, the movement trajectory of point B is an arc BB1 on a circle with point A as the center and AB as the radius. During the process of the positioning plate tilting up, it will interfere with the upper part of the fixed column. At this time, it is difficult to disengage the upper part of the fixed column from the positioning hole, and it is necessary to move the elastic transition part upward to make point A tilt up in order to disengage the upper part of the fixed column from the positioning hole.

[0028] Since the elastic transition part in the present invention is an arc, during the process of the positioning plate tilting up, the elastic transition unit changes from an arc to a straight line, making the length AB from point A to point B continuously increase. During the process of the positioning plate tilting up, the movement trajectory of point B is a line segment BB2 parallel to the vertical direction. During the process of the positioning plate tilting up, the positioning hole will not interfere with the upper part of the fixed column, and it is possible to conveniently disengage the upper part of the fixed column from the positioning hole and detach the positioning component from the fixed column to achieve disassembly.

[0029] The lower transition part is tangent to the pressing plate at their connection point to prevent the lower transition part 33 from directly contacting the installation part 1; the upper transition part 31 is higher than the upper surface of the positioning plate 20 due to design requirements, and during the process of the positioning plate tilting up, it can prevent the movement interference between the positioning plate and the fixed column.

[0030] As Figure 4 shown, the pressing plate includes a first plane 41, a second plane 43, and an arc surface 42; one end of the arc surface is fixedly connected to one end of the first plane, and the other end is fixedly connected to one end of the second plane; the end of the second plane 43 away from the arc surface is fixedly connected to the elastic transition part 30, the bending direction of the arc surface 42 faces the positioning area, and the inner walls of the corresponding parts on both sides of the opening 44 are in tight contact with the bottom surface of the annular notch.

[0031] During the operation of the compressor, vibrations will be generated. If the pressing force between the pressing plate and the installation part of the compressor is insufficient, the vibrations will be directly transmitted to the pressing plate, generating noise.

[0032] The first plane 41 and the second plane 43 are in direct contact with the installation part, and the arc surface plays a buffering role. When the vibrations of the compressor are transmitted to the first plane and the second plane, part of the vibration energy will be absorbed by the arc surface, which can effectively reduce noise; when the arc surface deforms, it generates an elastic force and presses the installation part through the first plane and the second plane, which can improve the reliability of the present invention and can effectively reduce noise.
