Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0038] As described in the background, industries such as air conditioning and heat pumps often utilize variable-frequency compressors with enthalpy-increasing valves. These compressors are typically connected to enthalpy-increasing valves. To prevent the valves from breaking due to compressor vibration during operation or transportation, they are typically secured with pipe fixing structures. However, existing pipe fixing structures have poor vibration damping, resulting in unstable installation of the enthalpy-increasing valves.

[0039] Based on this, please refer to Figure 1-Figure 5 The embodiment of the present invention provides a pipeline fixing shock-absorbing structure 100 and a compressor 1000, which can effectively improve the above-mentioned technical problems, that is, it has a good shock-absorbing effect and can improve the installation stability of the pipeline 300.

[0040] It should be noted that the first direction mentioned in the following content is Figure 1-Figure 5 The X direction is shown in the second direction. Figure 1-Figure 5 The Y direction is shown in the figure, and the third direction is Figure 1-Figure 5 The pipeline fixing and damping structure 100 and the compressor 1000 will be described in detail below.

[0041] Please refer to Figure 1 , Figure 1 This is a partial structural diagram of the compressor 1000 provided in this embodiment. The compressor 1000 includes a compressor body (not shown), a pipeline 300 and a pipeline fixing and shock-absorbing structure 100. The compressor body is fixedly connected to the management fixing structure. The pipeline fixing and shock-absorbing structure 100 is used to fix the pipeline 300 to improve the fixing and shock-absorbing effect of the pipeline 300 and avoid its breakage due to vibration generated during transportation or during operation of the compressor body.

[0042] It should be noted that this embodiment does not limit the type of pipeline 300, which can be an enthalpy increasing tube or other pipeline structure that requires shock absorption and fixation; that is, the pipeline fixing shock absorption structure 100 provided in this embodiment can perform shock absorption and fixation on the enthalpy increasing tube or other pipeline structures.

[0043] Specifically, please refer to Figure 2 , Figure 2This is a schematic structural diagram of the first perspective of the pipeline fixing shock absorbing structure 100 provided in this embodiment, combined with Figure 1 and Figure 2 The pipeline fixing shock-absorbing structure 100 includes a base 10 and a semicircular protrusion 20. The base 10 is used to be fixedly connected to the compressor body. Specifically, in this embodiment, the base 10 is fixedly connected to the fixing plate 200 of the compressor body; the semicircular protrusion 20 is arranged on the base 10, and a circular card groove 30 is opened between the semicircular protrusion 20 and the base 10, and the circular card groove 30 is used to be clamped with the pipeline 300; wherein, the circular card groove 30 is arranged to extend along the axial direction of the semicircular protrusion 20, and the peripheral wall of the circular card groove 30 is opened with a plurality of first shock-absorbing grooves 40, and the plurality of first shock-absorbing grooves 40 are arranged at intervals along the circumference of the circular card groove 30.

[0044] In other words, the base 10 can be fixedly connected to the compressor body, thereby enabling the integral installation of the pipeline fixing and shock-absorbing structure 100 on the compressor body. The circular slot 30 extends axially along the semicircular protrusion 20, aligning the installation extension direction of the pipeline 300 with the axial direction of the semicircular protrusion 20. This ensures that the pipeline 300 is securely engaged with the circular slot 30. Furthermore, the provision of multiple first shock-absorbing grooves 40 on the peripheral wall of the circular slot 30 enhances the shock-absorbing effect while securing the pipeline 300, thereby improving the installation stability of the pipeline 300.

[0045] It should be noted that the connection between the pipeline 300 and the circular slot 30 is an interference fit. Since the circular slot 30 is formed between the semicircular protrusion 20 and the base 10, part of the circular slot 30 is located on the semicircular protrusion 20, and the other part is located on the base 10; similarly, part of the first shock-absorbing groove 40 is located on the semicircular protrusion 20, and the other part is located on the base 10. In this way, after the pipeline 300 is connected to the circular slot 30, both the semicircular protrusion 20 and the base 10 can apply a clamping force to the pipeline 300 to wrap it, thereby improving its installation stability.

[0046] Moreover, since the semicircular protrusion 20 is semicircular in shape, it can match the pipeline structure, reducing the damage to the semicircular protrusion 20 caused by the stress generated when the pipeline is pulled out, thereby reducing the risk of breakage of the pipeline fixing shock-absorbing structure 100.

[0047] It should be noted that both the base 10 and the semicircular protrusion 20 are elastic members, thereby providing a cushioning effect for the pipeline 300 to achieve a shock-absorbing effect. Specifically, in this embodiment, the base 10 and the semicircular protrusion 20 are both made of EPDM rubber. Of course, in other embodiments, the base 10 and the semicircular protrusion 20 can also be made of other elastic materials such as nitrile rubber.

[0048] Optionally, the Shore hardness of the base 10 and the semicircular protrusion 20 is 55 to 65 degrees. Within this range, the shock absorption effect is better; for example, the Shore hardness can be 55 degrees, 58 degrees, 60 degrees, 62 degrees or 65 degrees, etc.

[0049] It should be noted that, in this embodiment, the circular slot 30 is a through slot, that is, the pipeline 300 is passed through the circular slot 30; of course, in some other embodiments, the circular slot 30 can also be a blind slot, so that one end of the pipeline 300 is directly connected to the circular slot 30.

[0050] In addition, it should be noted that since the multiple first shock-absorbing grooves 40 are arranged at intervals in the circumference of the circular clamping groove 30, a clamping protrusion is formed between two adjacent first shock-absorbing grooves 40. After the pipeline 300 is passed through the clamping groove, it can be supported and fixed with the multiple clamping protrusions, and since there is a gap between two adjacent clamping protrusions, when the clamping protrusion is compressed, it can provide a buffering and shock-absorbing effect for the pipeline 300.

[0051] Please continue to combine Figure 1 and Figure 2 To enhance the shock absorption effect, the base 10 is provided with a plurality of second shock absorbing grooves 13. These grooves 13 are located on a side of the base 10 away from the semicircular protrusions 20 and are spaced apart. As will be readily understood, after the base 10 is connected and secured to the fixing plate 200, the protrusions formed between the second shock absorbing grooves 13 can also abut against the fixing plate 200, thereby providing a buffering and shock absorption effect for the overall pipeline fixing and shock absorbing structure 100.

[0052] Furthermore, to facilitate installation and removal of the pipe 300, in this embodiment, the base 10 is provided with a mounting notch 14, which communicates with the circular slot 30 and extends through the bottom surface of the base 10 in a direction away from the semicircular protrusion 20. It is understood that when the pipe 300 needs to be installed or removed, the mounting notch 14 can be directly opened, and the pipe 300 can be snapped into or removed from the circular slot 30, thereby improving assembly efficiency.

[0053] Please refer to Figure 3 , Figure 3 A schematic diagram of the structure of the pipeline fixing shock absorbing structure 100 provided in this embodiment from a second perspective, combined with Figure 2 and Figure 3In order to better fix the base 10 and the fixing plate 200, in this embodiment, the circular slot 30 extends along the first direction, and the base 10 is provided with a first fixing hole 11 and a second fixing hole 12. The first fixing hole 11 and the second fixing hole 12 are spaced apart along the second direction and are respectively located on both sides of the semicircular protrusion 20. The first fixing hole 11 and the second fixing hole 12 are both extended along the third direction; wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0054] It should be noted that the first direction mentioned above is the axis direction of the semicircular protrusion 20. Figure 1-Figure 3 , two screws 400 can pass through the first fixing hole 11 and the second fixing hole 12 respectively, and be fixedly connected to the fixing plate 200.

[0055] Furthermore, in order to facilitate the installation of the screw 400, the semicircular protrusion 20 is provided with a first avoidance groove 21 and a second avoidance groove 22. The first avoidance groove 21 and the second avoidance groove 22 are arranged at intervals along the second direction, and the first avoidance groove 21 and the second avoidance groove 22 both penetrate through the top surface of the base 10 along the third direction; wherein, the first fixing hole 11 corresponds to the first avoidance groove 21, and the second fixing hole 12 corresponds to the second avoidance groove 22.

[0056] It should be noted that, due to the setting of the installation notch 14, in order to reduce the gap of the installation notch 14 when the base 10 is fixed on the fixing plate 200, Figure 3 In this embodiment, at least a portion of the first fixing hole 11 is located in the first avoidance groove 21, and at least a portion of the second fixing hole 12 is located in the second avoidance groove 22, and the distance L between the center of the first fixing hole 11 and the center of the second fixing hole 12 is less than the diameter D1 of the semicircular protrusion 20, that is, L<D1.

[0057] In this way, when the two screws 400 pass through the first fixing hole 11 and the second fixing hole 12 and connect and fix the base 10 to the fixing plate 200, since the base 10 has a certain elasticity, the screws 400 can apply a clamping force to the base 10, so that the part of the base 10 located on both sides of the installation notch 14 has a tendency to move toward the installation notch 14 and be compressed, thereby reducing the gap of the installation notch 14, being able to better clamp and fix the pipeline 300, and also improving the shock absorption effect.

[0058] Please refer to Figure 4 , Figure 4 This is a cross-sectional view of the pipeline fixing shock absorbing structure 100 provided in this embodiment, combined with Figure 4 In this embodiment, the height H1 of the center of the circular slot 30 is smaller than the height H2 of the base 10 , that is, H1 < H2 .

[0059] It should be noted that the height H1 refers to the distance between the center of the circular slot 30 and the bottom surface of the base 10, and the height H2 refers to the distance between the top surface and the bottom surface of the base 10. Figure 2 and Figure 4 Since the horizontal line of the top surface of the base 10 is higher than the horizontal line of the center of the circular slot 30, when the two screws 400 are fixed on the fixing plate 200, a clamping force can be applied to the base 10, thereby better clamping and fixing the pipe 300 connected in the circular slot 30, further improving the installation stability.

[0060] Please refer to Figure 5 , Figure 5 for Figure 4 A partial enlarged view of the middle A, combined with Figure 4 and Figure 5 In this embodiment, the center of the circular slot 30 coincides with the center of the semicircular protrusion 20 , that is, half of the circular slot 30 is located on the semicircular protrusion 20 , and the other half is located on the base 10 .

[0061] The inventors have found that the cross-sectional thickness of the semicircular protrusion 20 is related to the shock-absorbing effect. In order to further improve the shock-absorbing effect, optionally, the cross-sectional thickness T1 between the peripheral wall of the partial circular groove 30 located on the semicircular protrusion 20 and the outer surface of the semicircular protrusion 20 is in a ratio of 1.5 to 1.8 to the diameter D2 of the circular groove 30; that is, when the cross-sectional thickness is within this range, the shock-absorbing effect is better. For example, the ratio of T1 / D2 can be 1.5, 1.6, 1.7 or 1.8, etc.

[0062] Furthermore, the ratio of the cross-sectional thickness between the bottom wall of the plurality of first shock-absorbing grooves 40 located on the semicircular protrusion 20 and the outer surface of the semicircular protrusion 20 to the diameter of the circular slot 30 is 1.4 to 1.7; that is, when the cross-sectional thickness is within this range, the shock-absorbing effect is better. For example, the ratio of T2 / D2 can be 1.4, 1.45, 1.5, 1.55, 1.6, 1.65 or 1.7, etc.

[0063] It should be noted that the cross-sectional thickness T1 can also be understood as: the difference between the radius of the semicircular protrusion 20 and the radius of the circular groove 30; the cross-sectional thickness T2 can also be understood as: the difference between the radius of the semicircular protrusion 20 and the radius of the circle formed by the bottom wall of the multiple first shock-absorbing grooves 40.

[0064] In addition, it should be noted that, in this embodiment, the base 10 and the semicircular protrusion 20 are processed as an integral unit; of course, in some implementations thereof, the base 10 and the semicircular protrusion 20 can also be processed separately and then connected and fixed.

[0065] In summary, the embodiments of the present invention provide a pipeline fixing and damping structure 100 and a compressor 1000. The pipeline fixing and damping structure 100 includes a base 10 and a semicircular protrusion 20. The base 10 is used to be fixedly connected to the compressor body. The semicircular protrusion 20 is provided on the base 10. A circular slot 30 is provided between the semicircular protrusion 20 and the base 10. The circular slot 30 is used to be clamped with the pipeline 300. The circular slot 30 is provided along the axial direction of the semicircular protrusion 20, and the peripheral wall of the circular slot 30 is provided with a plurality of first damping grooves 40. The plurality of first damping grooves 40 are arranged at intervals along the circumference of the circular slot 30. It is understood that the base 10 can be fixedly connected to the compressor body to achieve the integral installation of the pipeline fixing and damping structure 100 on the compressor body. By extending the circular slot 30 along the axial direction of the semicircular protrusion 20, the installation extension direction of the pipeline 300 is the same as the axial direction of the semicircular protrusion 20, so that the pipeline 300 is firmly connected to the circular slot 30; and by providing multiple first shock-absorbing grooves 40 on the peripheral wall of the circular slot 30, it is possible to improve its shock-absorbing effect while fixing the pipeline 300, thereby improving the installation stability of the pipeline 300.

[0066] The compressor 1000 includes the pipeline fixing and damping structure 100 , and has all the functions and beneficial effects of the pipeline fixing and damping structure 100 .
