Description

Technical Field

[0001] The present invention relates to the technical field of packaging, in particular to a packaging structure of a compressor, a bottom plate component of the packaging structure, and a packaging product provided with the packaging structure. Background Art

[0002] Since the compressor contains high-precision parts and needs to be used in conjunction with the system, in order to ensure that the compressor is not damaged during storage and transportation, a special packaging structure is usually designed to package and protect the compressor. The existing packaging structure includes a cover plate and a bottom plate. A sleeve portion is provided on the cover plate to fix the top of the compressor, and a cavity matching the sleeve portion is provided on the bottom plate to accommodate the bottom of the compressor; wherein, in order to prevent the compressor from rotating relative to the bottom plate and the cover plate, three positioning columns are provided in the cavity, so that when the bottom of the compressor is placed in the cavity, the three positioning columns are inserted into the connecting holes of the three brackets at the bottom of the compressor to limit the rotation of the compressor relative to the bottom plate and improve the protection effect. However, the existing bottom plate design has the following defects: The positioning column is fixed in the cavity, resulting in extremely limited adjustable placement angles for the compressor on the base plate. In addition, the compressor is usually equipped with a liquid storage tank, and the relative positions of the liquid storage tank and the bracket on the compressor may be different for different models of compressors. The defects caused by the fixed design of the positioning column result in poor versatility and a small scope of application of the existing base plate, which also increases the packaging costs of manufacturers.

[0003] Secondly, since there is a certain height difference between the upper bracket and the bottom part of the compressor, and the height difference is small, in order to ensure that the cavity can support the bottom of the compressor when the positioning column is inserted into the connecting hole of the compressor bracket, the depth of the cavity cannot be too deep. This also leads to the cavity wrapping and supporting area of ​​the compressor body being extremely limited, thereby increasing the risk of the compressor tipping over. Summary of the invention

[0004] The first object of the present invention is to provide a base plate assembly which has strong versatility and wraps around the compressor body and has a large supporting area.

[0005] A second object of the present invention is to provide a packaging structure provided with the above-mentioned bottom plate assembly.

[0006] The third object of the present invention is to provide a packaging product provided with the above packaging structure.

[0007] To achieve the first object of the present invention, the present invention provides a bottom plate assembly, including a bottom plate, on which a cavity is provided. Among them, a first connecting portion and more than two positioning grooves are formed on the bottom plate, and the more than two positioning grooves are distributed around the cavity; the bottom plate assembly further includes a fixed sleeve, the fixed sleeve has a side wall, the side wall encloses a positioning cavity and more than two support grooves, the more than two support grooves are distributed around the positioning cavity, and a second connecting portion and a positioning buckle are formed on the fixed sleeve; when the fixed sleeve is assembled with the bottom plate, the second connecting portion is detachably connected to the first connecting portion, the positioning buckle is snap-fitted with one positioning groove, and the positioning cavity communicates with the cavity.

[0008] As can be seen from the above, adding a fixed sleeve enables the positioning cavity of the fixed sleeve to surround and support the body of the compressor, and the support grooves of the positioning sleeve can be used to limit and surround and support the support of the compressor, thereby reducing the risk of the compressor tipping over; in addition, by adjusting the snap connection between the positioning buckle on the fixed sleeve and different positioning grooves, the installation angle position between the fixed sleeve and the bottom plate can be adjusted, and then the placement angle position of the compressor placed on the bottom plate can be adjusted, effectively improving the versatility of the bottom plate assembly, expanding the applicable range of the bottom plate assembly, and at the same time reducing the packaging cost of the manufacturer.

[0009] A preferred solution is that a bottom wall is provided at the bottom of each support groove.

[0010] As can be seen from the above, the setting of the bottom wall can increase the structural strength of the fixed sleeve, avoid the fixed sleeve from being deformed by force and / or reduce the cracking probability of the fixed sleeve; in addition, based on the surrounding support of the positioning cavity for the body of the compressor, the setting of the bottom wall can also reduce the thickness of the bottom plate, thereby reducing the weight of the bottom plate and the production cost.

[0011] A further solution is that a supporting boss is formed at the top of the bottom wall, and there is a limiting gap between the supporting boss and the side wall.

[0012] As can be seen from the above, the supporting boss can better support the compressor, thereby reducing the pressure borne by the bottom wall and protecting the fixed sleeve; at the same time, since the supports of some compressors are in an inverted "U" shape, by forming a limiting gap between the supporting boss and the side wall, further limiting and fixing of the supports of the compressor can be achieved.

[0013] A further solution is that the positioning buckle is formed at the bottom of the bottom wall; the number of positioning grooves is an integer multiple of the number of positioning buckles, and each positioning buckle can be snap-fitted with one positioning groove.

[0014] As can be seen from the above, the above design makes the structure of the fixed sleeve more reasonable, and can ensure that no matter which set installation angle position the fixed sleeve is in, the cooperation between the positioning buckle and the positioning groove can always ensure the relative fixation between the fixed sleeve and the bottom plate.

[0015] A further solution is that the positioning groove and the positioning buckle both extend in an arc shape, and the arc is arranged concentrically with the cavity.

[0016] As can be seen from the above, the above design makes the structure of the fixing sleeve and the bottom plate more reasonable and facilitates the positioning buckle to be inserted into the positioning groove.

[0017] Another preferred solution is that the first connection part is snap-connected to the second connection part; or the first connection part is threadedly connected to the second connection part.

[0018] As can be seen from the above, the above designs can realize quick disassembly and assembly of the fixed sleeve and the base plate.

[0019] Another further solution is that there is a height difference between the bottom of the bracket groove and the bottom of the positioning cavity and an insertion portion is formed; when the fixing sleeve and the base plate are assembled, the insertion portion is inserted into the cavity and abuts against the inner wall of the cavity.

[0020] As can be seen from the above, inserting a portion of the fixed sleeve into the cavity can improve the connection strength between the fixed sleeve and the base plate, so as to better support and limit the compressor, and is also beneficial to improving the structural strength of the fixed sleeve and the base plate.

[0021] A further solution is that when the first connecting part and the second connecting part are snap-connected: the number of first connecting parts is between two and eight, more than two first connecting parts are evenly distributed at the opening along the opening of the cavity, and a first notch is formed between two adjacent first connecting parts; the second connecting part is located at the insertion part, and the number of the second connecting parts is less than or equal to the number of the first connecting parts; when the fixed sleeve is assembled with the base plate, each second connecting part can be inserted into the cavity from a first notch, and a second connecting part can be rotated to snap-connect with a first connecting part.

[0022] Another further solution is that when the first connection part is threadedly connected to the second connection part: the first connection part is an internal thread provided on the inner wall of the cavity, and the second connection part is an external thread provided on the outer periphery of the insertion part.

[0023] As can be seen from the above, the above design can ensure a reliable connection between the fixing sleeve and the base plate, and facilitates quick disassembly and assembly of the two.

[0024] A further solution is that a drainage hole and a drainage groove are provided on the bottom wall of the cavity, the drainage hole is located at the lowest point of the cavity and penetrates the bottom plate, and the drainage groove is connected to the drainage hole.

[0025] As can be seen from the above, the arrangement of the drainage holes and drainage grooves enables the water droplets condensed from water vapor to be discharged from the bottom plate through the drainage grooves and drainage holes, so as to ensure the dryness of the compressor and prevent water vapor from entering the compressor and causing quality problems.

[0026] A further solution is that a first positioning portion is provided on the bottom plate, and the first positioning portion is a second notch or a first direction mark.

[0027] As can be seen from the above, the first positioning portion is used to quickly identify the installation matching position when the bottom plate assembly is matched with other packaging components (such as the cover plate assembly), thereby ensuring the accurate matching position of the bottom plate assembly with other packaging components and reliably fixing the compressor.

[0028] A further solution is that the base plate is made of polypropylene or high-density polyethylene; and / or the fixing sleeve is made of polypropylene or high-density polyethylene.

[0029] It can be seen from the above that the above design can improve the chemical stability of the bottom plate assembly, so that the bottom plate assembly has the advantages of high strength and toughness, thereby effectively reducing transportation losses, improving recycling rates, and thus reducing packaging costs.

[0030] In order to achieve the second purpose of the present invention, the present invention provides a packaging structure, including a cover plate assembly, the cover plate assembly includes a cover plate, and a sleeve portion is formed on the cover plate, wherein the packaging structure also includes the above-mentioned bottom plate assembly, and a fixed position is formed between the sleeve portion and the mold cavity, the positioning cavity and the bracket groove.

[0031] As can be seen from the above, the packaging structure provided with the above-mentioned bottom plate assembly has the advantages of good support, strong versatility, and a wide range of applications, which is conducive to reducing the packaging costs of manufacturers.

[0032] A further solution is that the cover assembly also includes a relay sleeve, which is detachably connected to the sleeve portion, the relay sleeve and the sleeve portion are coaxially arranged, and a fixed position is formed between the relay sleeve, the sleeve portion and the cavity, the positioning cavity and the bracket groove.

[0033] As can be seen from the above, by adding a relay sleeve, the packaging structure can be adapted to compressors of different models and specifications through the relay sleeve, thereby further improving the versatility and practicality of the packaging structure and further reducing the manufacturer's packaging costs.

[0034] Another preferred solution is that the relay sleeve is threadedly connected to the sleeve portion; or the relay sleeve is snap-connected to the sleeve portion.

[0035] As can be seen from the above, the above design is conducive to the rapid disassembly and assembly between the relay sleeve and the sleeve portion.

[0036] A further solution is that when the relay sleeve is threadedly connected to the sleeve part: the sleeve part extends out of the bottom of the cover plate, the outer circumference of the sleeve part is provided with an external thread, and the inner ring of the relay sleeve is provided with an internal thread; or the inner ring of the sleeve part is provided with an internal thread, and the outer circumference of the relay sleeve is provided with an external thread.

[0037] As can be seen from the above, the above design makes the position between the relay sleeve and the sleeve portion adjustable, and the adjustment is convenient and easy to operate.

[0038] A further solution is that the packaging structure also includes a pressing plate, which is roughly in the shape of a chamfered pyramid, and the angle between the top surface of the pressing plate and the side surface of the pressing plate is between 60° and 85°, and the bottom surface of the pressing plate is adjacent to the top surface of the cover plate; and / or the cover plate is in the shape of a chamfered pyramid, and the angle between the top surface of the cover plate and the side surface of the cover plate is between 60° and 85°.

[0039] As can be seen from the above, the pressure plate can prevent the subsequent packaging belt from squeezing the cover plate, thereby protecting the cover plate and allowing the cover plate to be recycled to reduce packaging costs; and by designing the angle between the top and side surfaces of the pressure plate, the pressure-bearing capacity of the pressure plate can be improved, and the pressure plate can be prevented from bending the edge of the package due to uneven force under the squeezing of the packaging belt, thereby reducing the risk of damage to the compressor; through the design of the cover plate, the pressure-bearing capacity of the cover plate can be improved, and the cover plate can be prevented from bending the edge of the package due to uneven force under the squeezing of the packaging belt or the pressure plate, thereby reducing the risk of damage to the compressor.

[0040] A further solution is that a second positioning portion is provided on the cover plate, and the second positioning portion is a third notch or a second direction mark.

[0041] As can be seen from the above, this design enables the cover plate assembly and the bottom plate assembly to cooperate with each other to package the compressor, thereby realizing rapid identification of the installation and matching positions of the components, thereby ensuring the accurate matching positions of the components and reliably fixing the compressor.

[0042] A further solution is that the cover plate is made of polypropylene or high-density polyethylene; and / or the relay sleeve is made of polypropylene or high-density polyethylene.

[0043] It can be seen from the above that the above design can improve the chemical stability of the cover plate assembly, so that the bottom plate assembly has the advantages of high strength and toughness, thereby effectively reducing transportation losses, improving recycling rates, and thus reducing packaging costs.

[0044] In order to achieve the third objective of the present invention, the present invention provides a packaging product, including a compressor, which also includes the above-mentioned packaging structure, and the compressor is fixed in a fixed position.

[0045] As can be seen from the above, packaging products use the above packaging structure to package the compressor, which can not only better support and protect the compressor, but also reduce packaging costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] First embodiment of packaging structure The packaging structure 100 provided by the present invention can be used to package the compressor 10, so as to facilitate the storage and transportation of the compressor 10 and protect the compressor 10. Figure 1 and Figure 2 , including a base plate assembly 1, a cover plate assembly 2 and a pressure plate 3.

[0064] Combination Figure 3 The bottom plate assembly 1 includes a bottom plate 11 and a fixing sleeve 12. The fixing sleeve 12 is detachably connected to the bottom plate 11, and the mounting angle position of the fixing sleeve 12 relative to the bottom plate 11 is adjustable, so that the placement angle position of the packaged compressor 10 relative to the packaging structure 100 is adjustable.

[0065] Combination Figure 4 and Figure 5 The bottom plate 11 is provided with a cavity 111, and the cavity 111 is used to accommodate the bottom of the compressor 10. The number of cavities 111 is preferably more than two, so as to facilitate the packaging of more than two compressors 10, realize batch packaging of the compressors 10, and also help reduce packaging costs. The cavity 111 is concave from the top surface of the bottom plate 11 to the bottom surface of the bottom plate 11. Preferably, the supporting surface of the cavity 111 on the bottom of the compressor 10 can be set to a spherical crown surface or a plane according to the bottom surface shape of the compressor 10. For example, in this embodiment, the supporting surface of the cavity 111 on the bottom of the compressor 10 is a spherical crown surface.

[0066] The bottom wall 122 of the cavity 111 is provided with a drainage hole 1111 and a drainage groove 1112. The drainage hole 1111 is located at the lowest point of the support surface of the cavity 111 supporting the compressor 10, and the drainage hole 1111 penetrates the bottom plate 11 in the thickness direction of the bottom plate 11; the drainage groove 1112 is recessed from the above-mentioned support surface to the bottom of the bottom plate 11, and the drainage groove 1112 extends from the side wall of the cavity 111 to the drainage hole 1111 and is connected to the drainage hole 1111. By providing the drainage hole 1111 and the drainage groove 1112 in the cavity 111, the water droplets condensed by water vapor can be discharged from the bottom plate 11 through the drainage groove 1112 and the drainage hole 1111, so as to ensure the dryness of the compressor 10 and prevent water vapor from entering the compressor 10 to cause quality problems. Among them, the number of drainage grooves 1112 is preferably two to four, and the two to four drainage grooves 1112 are preferably evenly distributed along the circumference of the cavity 111, and the depth of the drainage grooves 1112 is preferably between 5 mm and 10 mm to ensure that water can smoothly flow through the drainage grooves 1112 to the drainage holes 1111; the diameter of the drainage holes 1111 is preferably between 10 mm and 20 mm to ensure that water can be discharged from the cavity 111 through the drainage holes 1111.

[0067] Combination Figure 5A first connecting portion 112 and a positioning groove 113 are also formed on the bottom plate 11. The first connecting portion 112 and the positioning groove 113 are both used to cooperate with the fixed sleeve 12 so that the fixed sleeve 12 can be firmly installed on the bottom plate 11 and the fixed sleeve 12 can be kept at a set installation angle position without moving, thereby ensuring the reliability of the packaged compressor 10 being fixed.

[0068] Combination Figure 6 The fixing sleeve 12 has a side wall 121, and the side wall 121 is surrounded by a positioning cavity 1211 and two or more bracket grooves 1212. The bracket groove 1212 is used to accommodate the bracket 101 on the compressor 10 and limit the bracket 101. The two or more bracket grooves 1212 are distributed around the positioning cavity 1211. In addition, a second connecting portion 1213 and a positioning buckle 1221 are formed on the fixing sleeve 12. When the fixing sleeve 12 is assembled with the bottom plate 11, the second connection portion 1213 is detachably connected with the first connection portion 112, a positioning buckle 1221 is engaged with a positioning groove 113, and the positioning cavity 1211 is connected with the mold cavity 111; wherein, the inner cavity wall of the positioning cavity 1211 is cylindrical, and matchingly, the inner cavity wall of the mold cavity 111 is also cylindrical, so that when the fixing sleeve 12 is assembled to the bottom plate 11, the inner cavity wall of the positioning cavity 1211 and the inner cavity wall of the mold cavity 111 are roughly coaxially arranged. In addition, the number of bracket grooves 1212 can be adjusted and designed according to the number of brackets 101 on the packaged compressor 10; generally, the number of bracket grooves 1212 is between two and four, and two to four bracket grooves 1212 are evenly distributed around the positioning cavity 1211; for example, in the present embodiment, the number of bracket grooves 1212 is three.

[0069] Preferably, there is a height difference between the bottom of the bracket groove 1212 and the bottom of the positioning cavity 1211 and an insertion portion 120 is formed; when the fixed sleeve 12 is assembled with the bottom plate 11, the insertion portion 120 is inserted into the cavity 111 and abuts against the inner wall of the cavity 111. By inserting a portion of the fixed sleeve 12 after installation into the cavity 111, the connection strength between the fixed sleeve 12 and the bottom plate 11 can be improved, so as to better support and limit the compressor 10, and it is also beneficial to improve the structural strength of the fixed sleeve 12 and the bottom plate 11.

[0070] In addition, in the present embodiment, a snap-on connection is preferably adopted between the second connection portion 1213 of the fixing sleeve 12 and the first connection portion 112 on the base plate 11; wherein, the number of the first connection portions 112 and the number of the second connection portions 1213 are preferably adapted to the number of the bracket slots 1212, that is, the number of the first connection portions 112 and the number of the second connection portions 1213 are preferably between two and eight, and more than two first connection portions 112 are evenly distributed along the circumference of the cavity 111, and more than two second connection portions 1213 are evenly distributed along the circumference of the positioning cavity 1211. Preferably, the number of the first connection portions 112 and the number of the second connection portions 1213 are both twice the number of the bracket slots 1212; as in the present embodiment, the number of the first connection portions 112 and the number of the second connection portions 1213 are both six; of course, the number of the second connection portions 1213 may also be less than the number of the first connection portions 112.

[0071] The first connection part 112 is preferably in the shape of a first hook, and the second connection part 1213 is in the shape of a second hook that matches the first hook, so that when the first connection part 112 and the second connection part 1213 are matched and connected, the first connection part 112 and the second connection part 1213 are hooked together to improve the firmness of the connection between the fixed sleeve 12 and the bottom plate 11. Among them, two adjacent first connection parts 112 form a first notch 1121 for the second connection part 1213 to pass through and enter the cavity 111, and the second connection part 1213 is located at the insertion part 120, so that the structure of the fixed sleeve 12 is more optimized and reasonable. When the fixed sleeve 12 is assembled with the bottom plate 11, each second connection part 1213 is inserted into the cavity 111 from a first notch 1121, and then the fixed sleeve 12 is rotated and adjusted to the desired installation angle position, so that a second connection part 1213 is rotated to be snap-fitted and connected with a first connection part 112.

[0072] The number of the positioning grooves 113 on the bottom plate 11 is more than two. Preferably, the number of the positioning grooves 113 is between two and eight, and the more than two positioning grooves 113 are preferably evenly distributed around the cavity 111. The number of the positioning buckles 1221 on the fixed sleeve 12 can be equal to the number of the positioning grooves 113, or less than the number of the positioning grooves 113. Preferably, the number of the positioning grooves 113 is an integer multiple of the number of the positioning buckles 1221, but each positioning buckle 1221 can be snap-connected with one positioning groove 113. For example, in this embodiment, there are six positioning grooves 113 and three positioning buckles 1221.

[0073] like Figure 6As shown, the fixed sleeve 12 preferably has a bottom wall 122 at the bottom of each bracket groove 1212, and the positioning buckle 1221 is preferably formed on the bottom wall 122; preferably, one positioning buckle 1221 is formed on one bottom wall 122. Further, both the positioning groove 113 and the positioning buckle 1221 extend in an arc, and the arc is concentric with the cavity 111, so that the structures of the fixed sleeve 12 and the bottom plate 11 are more reasonable, and at the same time, it is also convenient for the positioning buckle 1221 to be snapped into the positioning groove 113. Among them, the setting of the bottom wall 122 can increase the structural strength of the fixed sleeve 12, prevent the fixed sleeve 12 from deforming under force and / or reduce the cracking probability of the fixed sleeve 12; in addition, based on the surrounding support of the positioning cavity 1211 for the body of the compressor 10, the setting of the bottom wall 122 can also reduce the thickness of the bottom plate 11, thereby reducing the weight of the bottom plate 11 and the production cost. When it is necessary to adjust the installation angle position of the fixed sleeve 12 to adjust the placement angle position of the bracket 101 of the compressor 10, the positioning buckle 1221 on the fixed sleeve 12 is switched from the currently engaged positioning groove 113 to another positioning groove 113 that matches the same cavity 11 and is engaged, and the adjustment of the installation angle position of the fixed sleeve 12 can be completed.

[0074] In addition, a support boss 1222 is preferably formed at the top of the bottom wall 122. The support boss 1222 can better support the compressor 10, thereby reducing the pressure on the bottom wall 122 and playing a protective role for the fixed sleeve 12. Further, there is a limiting gap 12221 between the support boss 1222 and the side wall 121. Since the brackets 101 of some compressors 10 are in an inverted "U" shape, by forming a limiting gap 12221 between the support boss 1222 and the side wall 121, further limiting and fixing of the brackets 101 of the compressor 10 can be achieved.

[0075] By setting the fixed sleeve 12 to cooperate with the bottom plate 11, the positioning cavity 1211 of the fixed sleeve 12 can surround and support the body of the compressor 10, and the bracket groove 1212 of the positioning sleeve can be used to limit and surround and support the bracket 101 of the compressor 10, thereby reducing the risk of the compressor 10 tipping over; in addition, by adjusting the snap connection between the positioning buckle 1221 on the fixed sleeve 12 and different positioning grooves 113, the installation angle position between the fixed sleeve 12 and the bottom plate 11 can be adjusted, and then the placement angle position of the compressor 10 placed on the bottom plate 11 can be adjusted, effectively improving the versatility of the bottom plate assembly 1, expanding the applicable range of the bottom plate assembly 1, and at the same time, it can also reduce the packaging cost of the manufacturer.

[0076] Combined with Figure 7 , the cover assembly 2 includes a cover 21 and a relay sleeve 22. Combined with Figure 8A sleeve portion 211 is formed on the cover plate 21, and the number of the sleeve portions 211 is preferably more than two, and the more than two sleeve portions 211 correspond one-to-one to the more than two cavities 111 on the base plate 11, so that a sleeve portion 211 and a corresponding cavity 111 on the base plate 11, a positioning cavity 1211 of the fixed sleeve 12 matching the cavity 111, and a bracket groove 1212 form a fixed position, which is used to support and fix the compressor 10.

[0077] Combination Fig. 9 The number of relay sleeves 22 is preferably more than two, and more than two relay sleeves 22 correspond to more than two sleeve parts 211 one by one; one relay sleeve 22 is detachably connected to a corresponding sleeve part 211. When the relay sleeve 22 is installed on the sleeve part 211, the relay sleeve 22 and the sleeve part 211 are coaxially arranged; when the relay sleeve 22 participates in packaging the compressor 10, a fixed position is formed between the relay sleeve 22, the sleeve part 211, a corresponding cavity 111 on the bottom plate 11, a positioning cavity 1211 of the fixed sleeve 12 matching the cavity 111, and the bracket groove 1212.

[0078] Among them, the detachable connection method between the relay sleeve 22 and the sleeve portion 211 can be a threaded connection or a snap connection. For example, in the present embodiment, the connection method between the relay sleeve 22 and the sleeve portion 211 is a threaded connection; specifically, in the present embodiment, the sleeve portion 211 extends out from the bottom of the cover plate 21 (that is, the sleeve portion 211 extends toward the bottom plate 11), and the outer periphery of the sleeve portion 211 is provided with an external thread 2111, and the inner ring of the relay sleeve 22 is provided with an internal thread 221. When the relay sleeve 22 and the sleeve portion 211 are assembled, the relay sleeve 22 is sleeved on the sleeve portion 211, and the external thread 2111 is threadedly connected with the internal thread 221. This design makes the position between the relay sleeve 22 and the sleeve portion 211 adjustable, and the adjustment is convenient and easy to operate.

[0079] The arrangement of the relay sleeve 22 enables the packaging structure 100 to adapt to compressors 10 of different models and specifications through the relay sleeve 22, thereby further improving the versatility and practicality of the packaging structure 100 and further reducing the packaging cost of the manufacturer. For example, when the body diameter of the compressor 10 is small and / or the height of the upper cover is low, the relay sleeve 22 can be fixed on the sleeve portion 211, and the relay sleeve 22 does not participate in the packaging of the compressor 10. At this time, the main working part is the sleeve portion 211; when the body diameter of the compressor 10 is large and / or the height of the upper cover is high, the relay sleeve 22 can be used to move downward. At this time, the distance between the bottom of the relay sleeve 22 and the bottom plate 11 is smaller than the distance between the bottom of the sleeve portion 211 and the bottom plate 11, so that the relay sleeve 22 is still fixed on the sleeve portion 211 and participates in the packaging of the compressor 10, so as to form a fixed cavity with a higher height and a larger diameter, thereby improving the versatility of the packaging structure 100 and reducing the packaging cost. In order to ensure that the relay sleeve 22 can reliably and stably limit and fix the top of the compressor 10, a limiting slot 222 is preferably provided at the bottom of the relay sleeve 22 to limit and fix the top of the compressor 10.

[0080] In addition, the height of the relay sleeve 22 is between 30 mm and 60 mm. This size design can ensure that the relay sleeve 22 and the sleeve portion 211 can have a stable connection structure, and can enable the relay sleeve 22 to effectively position and support the top of the compressor 10. It can also ensure the structural strength of the relay sleeve 22 and avoid the relay sleeve 22 occupying space in the packaging structure 100 due to its excessive height, thereby facilitating the storage and transportation of packaging products using the packaging structure 100.

[0081] In this embodiment, the sleeve portion 211 preferably extends out of the main body of the base plate 11. Therefore, in order to increase the structural strength of the main body of the base plate 11 and the structural strength between the sleeve portion 211 and the main body of the base plate 11, reinforcing ribs 213 are provided on the main body of the base plate 11 and between the main body of the base plate 11 and the sleeve portion 211.

[0082] Combination Fig.10, the pressing plate 3 is roughly in the shape of an inverted pyramid; wherein the pressing plate 3 includes a plurality of pressurizing strips 31 distributed side by side, the plurality of pressurizing strips 31 are arranged closely together, and the plurality of pressurizing strips 31 are arranged in the shape of an inverted pyramid; preferably, the pressing plate 3 also includes two or more fixed strips 32, the distribution direction of the two or more fixed strips 32 is perpendicular to the distribution direction of the plurality of pressurizing strips 31, and the fixed strips 32 are perpendicular to the pressurizing strips 31. There is preferably a spacing between two adjacent fixed strips 32 to reduce the weight of the pressing plate 3. The fixed strips 32 can be used to improve the overall structural strength of the pressing plate 3, and can also play a role in connecting the plurality of pressurizing strips 31. The pressing plate 3 can prevent the subsequent packaging belt from squeezing the cover plate 21, thereby protecting the cover plate 21, so that the cover plate 21 can be recycled to reduce the packaging cost.

[0083] Furthermore, the angle a between the top surface of the pressing plate 3 and the side surface of the pressing plate 3 is preferably between 60° and 85°, that is, the optimal inward inclination angle b of the side surface of the pressing plate 3 is between 5° and 30°. When the pressing plate 3 cooperates with the cover plate assembly 2 to package the compressor 10, the bottom surface of the pressing plate 3 is adjacent to the top surface of the cover plate 21. This design can improve the pressure bearing capacity of the pressing plate 3, avoid the bending of the packaging edge due to uneven force of the pressing plate 3 under the compression of the packaging belt, and thus reduce the risk of damage to the compressor 10. Among them, the pressure slats 31 and the fixed slats 32 are preferably both wooden boards; the bottom plate 11 is preferably made of polypropylene or high-density polyethylene, and the fixed sleeve 12 is preferably made of polypropylene (PP) or high-density polyethylene (HDPE), so as to improve the chemical stability of the bottom plate assembly 1, so that the bottom plate assembly 1 has the advantages of high strength and toughness, thereby effectively reducing transportation losses, improving recycling rates, and thus reducing packaging costs; the cover plate 21 is preferably made of polypropylene or high-density polyethylene; the relay sleeve 22 is preferably made of polypropylene or high-density polyethylene, so as to improve the chemical stability of the cover plate assembly 2, so that the bottom plate assembly 1 has the advantages of high strength and toughness, thereby effectively reducing transportation losses, improving recycling rates, and thus reducing packaging costs.

[0084] In addition, the bottom plate 11 is preferably provided with a first positioning portion 114, which is preferably a second notch; the cover plate 21 is preferably provided with a second positioning portion 212, which is preferably a third notch; this design enables the cover plate assembly 2 and the bottom plate assembly 1 to cooperate in packaging the compressor 10, and to quickly identify the installation and matching positions of the components, thereby ensuring the accurate matching positions of the components and reliably fixing the compressor 10. Of course, other optional solutions, in other embodiments, the first positioning portion 114 can also be a first direction mark; similarly, the second positioning portion 212 can be a second direction mark.

[0085] Preferably, the packaging structure 100 may also include at least one set of relay components, which include a partition, a fixed sleeve 12 (consistent with the fixed sleeve 12 structure of the bottom plate assembly 1) and a relay sleeve 22 (consistent with the relay sleeve 22 structure of the cover plate assembly 2); wherein the top surface of the partition is provided with a cavity 111, a first connecting portion 112 and a positioning groove 113 (consistent with the cavity 111, the first connecting portion 112 and the positioning groove 113 structure on the bottom plate 11), and the bottom surface of the partition is provided with a sleeve portion 211 (consistent with the sleeve portion 211 structure on the cover plate 21). The relay components enable the packaging structure 100 to better stack the compressor 10 in multiple layers and ensure the stability of the multi-layer stacked compressor 10.

[0086] In summary, it can be seen that through the design of the packaging structure 100 of the present invention, the types of compressors 10 that can be packaged by the packaging structure 100 are increased, the packaging commonality is improved, and the packaging cost is reduced; at the same time, under the premise that the packaging stability is guaranteed, the packaging material is selected from plastic materials with higher hardness and strength (polypropylene or high-density polyethylene and other materials), so that the chemical stability and wear resistance are good, the recycling and reuse rate is improved, and the stress resistance can be increased, thereby further improving the packaging strength, and the transportation loss can also be further improved to reduce pollution and save costs; further, the structural design of the pressure plate 3 makes the force more concentrated and uniform, avoiding the risk of deformation of the packaging edge.

[0087] Second embodiment of packaging structure Reference Fig.11 and Fig.12 The difference between this embodiment and the first embodiment of the packaging structure lies in the connection structure of the first connection part and the second connection part. In this embodiment: The first connection part 411 and the second connection part 421 are not assembled in a snap-fit ​​connection manner, but in a threaded connection manner, specifically: The first connection part 411 is an internal thread provided on the inner wall of the cavity 40, and the second connection part 421 is an external thread provided on the outer periphery of the insertion part of the fixed sleeve 42; when the fixed sleeve 42 is assembled with the bottom plate, the insertion part is inserted into the cavity 40, and the external thread on the insertion part is threadedly connected with the internal thread in the cavity 40. This design enables reliable connection between the fixed sleeve 42 and the bottom plate 41, and also facilitates quick disassembly and assembly of the two.

[0088] The remaining structures of this embodiment are the same as those of the first embodiment of the packaging structure, so they will not be described again here.

[0089] The third embodiment of the packaging structure Reference Figures 13 to 16 The difference between this embodiment and the above-mentioned embodiment lies in the structure of the cover plate assembly. Specifically, in this embodiment: The sleeve portion 511 on the cover plate 51 no longer extends out of the cover plate 51, but is built into the cover plate 51, and since the sleeve portion 511 no longer extends out of the cover plate 51, the sleeve portion 511 no longer has an outer circumferential wall. In order to adapt to the current design of the sleeve portion 511, an internal thread 5111 is provided on the inner circumferential wall of the sleeve portion 511; correspondingly, the relay sleeve 52 no longer has an internal thread on the inner circumferential wall, but an external thread 521 is provided on the outer circumferential wall of the relay sleeve 52.

[0090] When the relay sleeve 52 is assembled with the sleeve portion 511, the sleeve portion 511 is inserted into the relay sleeve 52, so that the external thread 521 of the relay sleeve 52 is threadedly connected with the internal thread 5111 of the sleeve portion 511; when the relay sleeve 52 is not needed to package the compressor 50, the relay sleeve 52 can be screwed into the sleeve portion 511 to be hidden, or the relay sleeve 52 can be removed from the sleeve portion 511; when the relay sleeve 52 is needed to package the compressor 50, a part of the relay sleeve 52 is threadedly connected to the sleeve portion 511 with a sufficient length, and the other part of the relay sleeve 52 extends out of the sleeve portion 511 to limit and fix the top of the compressor 50.

[0091] Preferably, since the sleeve portion 511 is embedded in the cover plate 51, the cover plate 51 can be hollowed out 512 between adjacent sleeve portions 511 to reduce the weight of the cover plate 51, save materials for making the cover plate 51, and prevent the compressor 50 from being damaged due to excessive pressure exerted on the compressor 50 due to the excessive weight of the cover plate 51. Preferably, the sleeve portion 511 penetrates the cover plate 51.

[0092] In addition, the cover plate 51 is in the shape of a chamfered pyramid, and the angle between the top surface of the cover plate 51 and the side surface of the cover plate 51 is between 60° and 85°. This design can improve the pressure-bearing capacity of the cover plate 51, and avoid the bending of the packaging edge of the cover plate 51 due to uneven force under the squeezing of the packaging belt, thereby reducing the risk of damage to the compressor 50; at the same time, based on the fact that the cover plate 51 is set to be in the shape of a chamfered pyramid, the use of a pressure plate can be eliminated when packaging the compressor 50, thereby reducing the packaging cost.

[0093] The remaining structures of this embodiment are the same as those of the first embodiment or the second embodiment of the packaging structure, and thus will not be described again here.

[0095] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
