[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0033] The vibration reduction weight block 100 according to an embodiment of the present utility model is described below with reference to the accompanying drawings. Figure 1-Figure 7 As shown, the vibration-damping weight 100 according to the embodiment of the utility model includes a body 1 and a protrusion 2 .

[0034] The body 1 has a matching hole 11. The clamping protrusion 2 is provided on the body 1, and at least a part of the clamping protrusion 2 is located in the matching hole 11. At least a part of the clamping protrusion 2 is movably provided along the radial direction of the matching hole 11.

[0035] According to the embodiment of the utility model, the vibration-damping weight block 100 enables at least a portion of the locking protrusion 2 to be movably arranged along the radial direction of the matching hole 11, so that the matching hole 11 can accommodate pipelines 200 of different diameters, thereby improving the versatility of the vibration-damping weight block 100.

[0036] Specifically, the diameter of the matching hole 11 is D, and when the matching hole 11 does not accommodate the pipeline 200, the size of the clamping protrusion 2 in the radial direction of the matching hole 11 is L, then the matching hole 11 can accommodate the pipeline 200 with a diameter greater than or equal to (DL) and less than or equal to D. When the diameter of the pipeline 200 is equal to (DL), after the pipeline 200 is accommodated in the matching hole 11 (that is, after the pipeline 200 passes through the matching hole 11), the at least part of the clamping protrusion 2 will not move outward in the radial direction of the matching hole 11; when the diameter of the pipeline 200 is greater than (DL) and less than or equal to D, after the pipeline 200 is accommodated in the matching hole 11, the at least part of the clamping protrusion 2 moves outward in the radial direction of the matching hole 11, and the larger the diameter of the pipeline 200, the greater the displacement of the at least part of the clamping protrusion 2 in the radial direction of the matching hole 11, until the inner edge of the clamping protrusion 2 is substantially flush with the wall surface of the matching hole 11.

[0037] Therefore, the vibration-damping counterweight 100 according to the embodiment of the utility model has the advantages of strong versatility and is conducive to production control.

[0038] like Figure 1-Figure 7 As shown, the vibration-damping counterweight 100 according to the embodiment of the utility model comprises a body 1 and a cam 2. The body 1 has a matching hole 11, and the matching hole 11 passes through the body 1, so that the vibration-damping counterweight 100 can be sleeved on the pipeline 200 of the compressor, that is, the pipeline 200 of the compressor can pass through the matching hole 11 of the vibration-damping counterweight 100.

[0039] The clamping protrusion 2 is provided on the body 1, and at least a part of the clamping protrusion 2 is located in the matching hole 11. At least a part of the clamping protrusion 2 is movably provided along the radial direction of the matching hole 11.

[0040] In one embodiment of the utility model, the wall surface of the matching hole 11 is provided with a receiving hole extending in the radial direction of the matching hole 11. A part of the clamping protrusion 2 is located in the receiving hole. Alternatively, the clamping protrusion 2 is opposite to the receiving hole in the radial direction of the matching hole 11, that is, the clamping protrusion 2 is located outside the receiving hole. The vibration-damping counterweight 100 further includes an elastic member, one end of which is connected to the clamping protrusion 2, and the other end of the elastic member is matched with the wall surface of the receiving hole.

[0041] When the diameter of the pipeline 200 is equal to (DL), after the pipeline 200 is accommodated in the matching hole 11, the clamping protrusion 2 will not move outward in the radial direction of the matching hole 11, and the elastic member will not be compressed. When the diameter of the pipeline 200 is greater than (DL) and less than or equal to D, after the pipeline 200 is accommodated in the matching hole 11, the clamping protrusion 2 will move outward in the radial direction of the matching hole 11, and the elastic member will be compressed. The larger the diameter of the pipeline 200, the greater the displacement of the clamping protrusion 2 in the radial direction of the matching hole 11, until the entire clamping protrusion 2 is accommodated in the accommodation hole, at which time the inner edge of the clamping protrusion 2 is roughly flush with the wall surface of the matching hole 11.

[0042] In another embodiment of the utility model, the clamping protrusion 2 is arranged on the wall surface of the matching hole 11, and the clamping protrusion 2 is an elastic clamping protrusion. In this way, the structure of the vibration-damping counterweight 100 can be made simpler and more reasonable. When the diameter of the pipeline 200 is equal to (DL), the clamping protrusion 2 will not be compressed after the pipeline 200 is accommodated in the matching hole 11. When the diameter of the pipeline 200 is greater than (DL) and less than or equal to D, the clamping protrusion 2 is compressed after the pipeline 200 is accommodated in the matching hole 11, and the larger the diameter of the pipeline 200, the greater the degree of compression of the clamping protrusion 2.

[0043] like Figure 5-Figure 7 As shown, the body 1 is provided with a receiving chamber 12, and the receiving chamber 12 is opposite to the clamping protrusion 2 in the radial direction of the matching hole 11, and the receiving chamber 12 is adjacent to the clamping protrusion 2 in the radial direction of the matching hole 11. In other words, the receiving chamber 12 is located outside the clamping protrusion 2. Thus, the receiving chamber 12 can be used to accommodate the clamping protrusion 2 compressed outward, so that the compression amount of the clamping protrusion 2 can be effectively increased. In other words, a clamping protrusion 2 with a larger size in the radial direction of the matching hole 11 can be arranged on the wall surface of the matching hole 11, so that the matching hole 11 can accommodate a pipeline 200 with a larger diameter range, so as to further improve the versatility of the vibration-damping counterweight 100.

[0044] Optionally, the clamping protrusion 2 may include a plurality of sub-clamping protrusions, which are arranged at intervals along the circumference of the matching hole 11. Therefore, when the pipeline 200 is accommodated in the matching hole 11, the plurality of sub-clamping protrusions surround and abut against the pipeline 200, so that the vibration-damping counterweight 100 can be more firmly assembled on the pipeline 200, thereby improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100 and improving the assembly consistency of the vibration-damping counterweight 100.

[0045] Accordingly, the accommodating cavity 12 may include a plurality of sub-accommodating cavities, which are arranged at intervals along the circumference of the matching hole 11. The plurality of sub-accommodating cavities and the plurality of sub-clamping protrusions are opposite to and adjacent to each other in the radial direction of the matching hole 11. This can make the structure of the vibration-damping counterweight 100 more reasonable.

[0046] like Figure 6 As shown, the clamping protrusion 2 is annular. The circumference of the clamping protrusion 2 is consistent with the circumference of the matching hole 11. Therefore, when the pipeline 200 is accommodated in the matching hole 11, the clamping protrusion 2 surrounds and abuts against the pipeline 200, so that the vibration-damping counterweight 100 can be more firmly assembled on the pipeline 200, thereby improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100 and improving the assembly consistency of the vibration-damping counterweight 100.

[0047] Accordingly, the accommodating cavity 12 is annular, and the circumferential directions of the accommodating cavity 12, the circumferential directions of the clamping protrusion 2 and the circumferential directions of the matching hole 11 are consistent with each other, thereby making the structure of the vibration-damping counterweight 100 more reasonable.

[0048] like Figure 5 and Figure 6 As shown, there are multiple clamping protrusions 2, and the multiple clamping protrusions 2 are arranged at intervals along the extension direction of the matching hole 11. There are multiple accommodating cavities 12, and the multiple accommodating cavities 12 are arranged at intervals along the extension direction of the matching hole 11. The multiple clamping protrusions 2 and the multiple accommodating cavities 12 are opposite to each other and adjacent to each other in the radial direction of the matching hole 11. Therefore, when the pipeline 200 is accommodated in the matching hole 11, the multiple clamping protrusions 2 surround and abut against the pipeline 200, so that the vibration-damping counterweight 100 can be more firmly assembled on the pipeline 200, thereby improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100 and improving the assembly consistency of the vibration-damping counterweight 100.

[0049] like Figure 5-Figure 7 As shown, the clamping protrusion 2 includes a clamping portion 21, a first connecting portion 22 and a second connecting portion 23. The clamping portion 21 is located in the matching hole 11, and the clamping portion 21 has a first end 211 and a second end 212 opposite to each other in the extending direction of the matching hole 11. Figure 5-Figure 7 As shown by arrow C in FIG.

[0050] Each of the first connection portion 22 and the second connection portion 23 is arranged obliquely relative to the extension direction of the matching hole 11, that is, each of the first connection portion 22 and the second connection portion 23 is not parallel to the extension direction of the matching hole 11. The outer end 221 of the first connection portion 22 and the outer end 231 of the second connection portion 23 are both connected to the wall surface of the matching hole 11, the inner end 222 of the first connection portion 22 is connected to the first end 211 of the engaging portion 21, and the inner end 232 of the second connection portion 23 is connected to the second end 212 of the engaging portion 21. In other words, the engaging portion 21 is located between the first connection portion 22 and the second connection portion 23 in the extension direction of the matching hole 11. In the inner and outer directions as Figure 6 As shown by the arrow D in FIG. In which, inward refers to the direction along the radial direction of the matching hole 11 adjacent to the central axis of the matching hole 11, and outward refers to the direction along the radial direction of the matching hole 11 away from the central axis of the matching hole 11.

[0051] When the pipeline 200 is accommodated in the matching hole 11, the engaging portion 21 abuts against the pipeline 200, and the first connecting portion 22 and the second connecting portion 23 move toward the direction of the adjacent accommodating cavity 12 (move outward) so that the engaging portion 21 moves toward the direction of the adjacent accommodating cavity 12, thereby making it easier for the locking protrusion 2 to be compressed, so that the vibration damping counterweight 100 and the pipeline 200 can be assembled together more easily.

[0052] Optionally, the engaging portion 21 is parallel to the extending direction of the matching hole 11. This can increase the contact area between the engaging portion 21 and the pipeline 200, so that the vibration-damping counterweight 100 can be more stably assembled on the pipeline 200, thereby improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100 and improving the assembly consistency of the vibration-damping counterweight 100.

[0053] like Figure 6 and Figure 7 As shown, the wall surface of the accommodating cavity 12 includes a first wall surface 121, a second wall surface 122, a third wall surface 125, a fourth wall surface 126, an inner wall surface 123, and an outer wall surface 124. The first wall surface 121 and the second wall surface 122 are opposite to each other in the extension direction of the matching hole 11, and the inner wall surface 123 and the outer wall surface 124 are opposite to each other in the radial direction of the matching hole 11. The inner wall surface 123 is opposite to the engaging portion 21 in the radial direction of the matching hole 11, so that the inner wall surface 123 is located between the engaging portion 21 and the outer wall surface 124 in the radial direction of the matching hole 11.

[0054] Each of the third wall surface 125 and the fourth wall surface 126 is arranged obliquely relative to the extension direction of the matching hole 11, that is, each of the third wall surface 125 and the fourth wall surface 126 is not parallel to the extension direction of the matching hole 11. The third wall surface 125 is connected to each of the first wall surface 121 and the inner wall surface 123, and the fourth wall surface 126 is connected to each of the second wall surface 122 and the inner wall surface 123.

[0055] That is, the outer end of the third wall surface 125 is connected to the inner end of the first wall surface 121, the inner end of the third wall surface 125 is connected to the inner wall surface 123, the outer end of the fourth wall surface 126 is connected to the inner end of the second wall surface 122, and the inner end of the fourth wall surface 126 is connected to the inner wall surface 123. The third wall surface 125 and the first connecting portion 22 are opposite to each other in the radial direction of the matching hole 11, and the fourth wall surface 126 and the second connecting portion 23 are opposite to each other in the radial direction of the matching hole 11.

[0056] Therefore, when assembling the vibration-damping weight block 100 and the pipeline 200, the first connecting portion 22 and the second connecting portion 23 can be more easily moved toward the direction adjacent to the accommodating cavity 12, so that the locking protrusion 2 can be more easily compressed, so that the vibration-damping weight block 100 and the pipeline 200 can be assembled together more easily.

[0057] like Figure 1-Figure 7 As shown, there are two fitting holes 11, one of which is located in the middle of the body 1 to form a central fitting hole 11a, and the other fitting hole 11 is located between the middle of the body 1 and the edge of the body 1 to form an offset fitting hole 11b. The pipeline 200 passes through one of the central fitting hole 11a and the offset fitting hole 11b.

[0058] When the gap between the pipeline 200 and other components is large, the center matching hole 11a matches with the pipeline 200, that is, the pipeline 200 passes through the center matching hole 11a. Since the center matching hole 11a is located in the middle of the body 1, even if the vibration-damping counterweight 100 rotates due to the vibration of the pipeline 200, the vibration-damping counterweight 100 rotates around its own central axis, so that the position of the center of gravity of the vibration-damping counterweight 100 will not be changed. In addition, since the center matching hole 11a is located in the middle of the body 1, no matter at which angle the vibration-damping counterweight 100 is installed, the position of the center of gravity of the vibration-damping counterweight 100 will not be changed.

[0059] By setting a central matching hole 11a in the middle of the main body 1, not only there is no problem of assembly consistency when assembling multiple vibration-damping counterweights 100, thereby improving the assembly efficiency of the vibration-damping counterweights 100, but also the position of the center of gravity of the vibration-damping counterweight 100 will not be changed due to the vibration of the pipeline 200, thereby further improving the shock-absorbing and noise-reducing effect of the vibration-damping counterweight 100.

[0060] In most cases, the central fitting hole 11a fits with the pipe 200. Only when the clearance between the pipe 200 and other components is small, the offset fitting hole 11b fits with the pipe 200, that is, the pipe 200 passes through the offset fitting hole 11b.

[0061] Correspondingly, there are two clamping protrusions 2, one clamping protrusion 2 is located in the central matching hole 11a, and the other clamping protrusion 2 is located in the offset matching hole 11b. In other words, the two clamping protrusions 2 are located in the two matching holes in a one-to-one correspondence.

[0062] The shapes, structures, and matching relationships between the protrusions 2 in the central matching hole 11a and the protrusions 2 in the offset matching hole 11b and other parts are as described above, and will not be described again. For example, the body 1 is provided with two accommodating cavities 12, one accommodating cavity 12 is opposite to and adjacent to the protrusions 2 in the central matching hole 11a in the radial direction of the central matching hole 11a, and the other accommodating cavity 12 is opposite to and adjacent to the protrusions 2 in the offset matching hole 11b in the radial direction of the offset matching hole 11b.

[0063] like Figure 1-Figure 5 As shown, the body 1 also has a balancing hole 13, and the balancing hole 13 and the offset matching hole 11b are symmetrically arranged relative to the central matching hole 11a. Therefore, when the central matching hole 11a is matched with the pipeline 200, the eccentricity of the vibration-damping counterweight 100 can be further avoided, thereby further improving the vibration and noise reduction effect of the vibration-damping counterweight 100.

[0064] Optionally, the balancing hole 13 passes through the body 1 along the extension direction of the matching hole, so as to further improve the symmetry between the balancing hole 13 and the offset matching hole 11b. Thus, when the central matching hole 11a is matched with the pipeline 200, the eccentricity of the vibration-damping counterweight 100 can be further avoided, thereby further improving the vibration and noise reduction effect of the vibration-damping counterweight 100.

[0065] Optionally, there are three clamping protrusions 2, which are respectively located in the central matching hole 11a, the offset matching hole 11b and the balancing hole 13. In other words, a clamping protrusion 2 is also provided in the balancing hole 13 to further improve the symmetry of the balancing hole 13 and the offset matching hole 11b. Therefore, when the central matching hole 11a is matched with the pipeline 200, the eccentricity of the vibration-damping counterweight 100 can be further avoided, thereby further improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100.

[0066] Further optionally, the shape, structure, and matching relationship between the protrusion 2 in the balancing hole 13 and other parts are as described above, and will not be described again here. For example, the body 1 is further provided with a third accommodating cavity 12, and the third accommodating cavity 12 is opposite and adjacent to the protrusion 2 in the balancing hole 13 in the radial direction of the balancing hole 13. In this way, the symmetry between the balancing hole 13 and the offset matching hole 11b can be further improved, so that when the central matching hole 11a is matched with the pipeline 200, the eccentricity of the vibration-damping counterweight 100 can be further avoided, thereby further improving the vibration-damping and noise-reducing effect of the vibration-damping counterweight 100.

[0067] The utility model also discloses a compressor. According to an embodiment of the utility model, the compressor comprises a vibration-damping counterweight block 100 and a pipeline 200. The pipeline 200 passes through the matching hole 11 of the vibration-damping counterweight block 100, and the clamping protrusion 2 of the vibration-damping counterweight block 100 abuts against the pipeline 200.

[0068] The compressor according to the embodiment of the utility model has the advantages of being easy to control in production, etc.

[0069] The utility model also discloses a refrigeration device. The refrigeration device according to an embodiment of the utility model comprises the compressor of the utility model.
