Description

TECHNICAL FIELD

[0001] The present application relates to the packaging technical field, in particular, it relates to a packaging structure of a compressor, and a bottom plate assembly of the packaging structure, and a packaging product provided with the packaging structure. BACKGROUND

[0002] Since the compressor contains high-precision parts and needs to be used with a 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 part is arranged on the cover plate to fix the top of the compressor. The bottom plate is provided with a cavity matched with the sleeve part to accommodate the bottom of the compressor. In order to prevent the compressor from rotating relative to the bottom plate and the cover plate, three positioning columns are arranged in the cavity. When the bottom of the compressor is placed in the cavity, the three positioning columns are inserted into the connecting holes of the three supports on 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:

[0003] The setting position of the positioning column in the cavity is fixed, which limits the adjustable placement angle position of the compressor placed on the bottom plate. In addition, the compressor usually has a liquid storage tank, and the relative position between the liquid storage tank and the support on the compressor may be different for different models of compressors. The defects caused by the fixed design of the foregoing positioning column result in poor universality and small application range of the existing bottom plate, thereby increasing the packaging cost of the manufacturer.

[0004] Secondly, since the support on the compressor has a certain height difference with the bottom part, 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 support on the compressor, the depth of the cavity cannot be too deep, which also limits the wrapping and supporting area of the cavity to the body of the compressor, thereby increasing the risk of the compressor falling. SUMMARY

[0005] The first object of the present application is to provide a bottom plate assembly with strong universality and large wrapping and supporting area to the body of the compressor.

[0006] The second object of the present application is to provide a packaging structure provided with the foregoing bottom plate assembly.

[0007] The third object of the present application is to provide a packaging product provided with the foregoing packaging structure.

[0008] In order to achieve the first object of the present application, the present application provides a bottom plate assembly, comprising a bottom plate, wherein the bottom plate is provided with a cavity, the bottom plate is formed with a first connecting portion and two or more positioning grooves, and the two or more positioning grooves are distributed around the cavity; the bottom plate assembly further comprises a fixing sleeve, the fixing sleeve has a side wall, the side wall surrounds a positioning cavity and two or more support grooves, the two or more support grooves are distributed around the positioning cavity, the fixing sleeve is formed with a second connecting portion and a positioning buckle, when the fixing sleeve is assembled with the bottom plate, the second connecting portion is detachably connected with the first connecting portion, the positioning buckle is clamped and connected with one of the positioning grooves, and the positioning cavity is communicated with the cavity.

[0009] As can be seen from the above, the fixing sleeve is additionally provided, so that the positioning cavity of the fixing sleeve can surround and support the body of the compressor, and the support groove of the fixing sleeve can be used for limiting and surrounding the support of the compressor, thereby reducing the risk of the compressor falling; in addition, by adjusting the clamping connection between the positioning buckle on the fixing sleeve and different positioning grooves, the installation angle position adjustment between the fixing sleeve and the bottom plate can be realized, and then the placement angle position adjustment of the compressor placed on the bottom plate can be realized, thereby effectively improving the universality of the bottom plate assembly, expanding the application range of the bottom plate assembly, and also reducing the packaging cost of manufacturers.

[0010] A preferred scheme is that a bottom wall is arranged at the bottom of each support groove.

[0011] As can be seen from the above, the arrangement of the bottom wall can increase the structural strength of the fixing sleeve, avoid stress deformation of the fixing sleeve and / or reduce the cracking probability of the fixing sleeve; in addition, based on the surrounding support of the body of the compressor by the positioning cavity, the arrangement of the bottom wall can also reduce the thickness of the bottom plate, thereby reducing the weight and production cost of the bottom plate.

[0012] A further scheme is that a supporting boss is formed at the top of the bottom wall, and a limiting gap is formed between the supporting boss and the side wall.

[0013] As can be seen from the above, the supporting boss can better support the compressor, thereby reducing the pressure intensity on the bottom wall and protecting the fixing sleeve; at the same time, since the support of part of the compressors is in the shape of an inverted "n", by forming the limiting gap between the supporting boss and the side wall, the support of the compressor can be further limited and fixed.

[0014] A still further scheme is that the positioning buckle is formed at the bottom of the bottom wall; the number of the positioning grooves is an integer multiple of the number of the positioning buckles, and each positioning buckle can be clamped and connected with one of the positioning grooves.

[0015] As can be seen from the above, the above design makes the structure of the fixing sleeve more reasonable, and can ensure that no matter which installation angle position the fixing sleeve is in, the cooperation between the positioning buckle and the positioning groove can always ensure the relative fixation between the fixing sleeve and the bottom plate.

[0016] Further, the positioning slot and the positioning buckle are both arc-shaped, and the arcs are concentric with the cavity.

[0017] As can be seen from the above, the design makes the structure of the fixing sleeve and the bottom plate more reasonable and facilitates the positioning buckle to be clamped into the positioning slot.

[0018] Another preferred embodiment is that the first connecting part is clamped with the second connecting part, or the first connecting part is screwed with the second connecting part.

[0020] Another further embodiment is that the bottom of the bracket slot and the bottom of the positioning cavity have a height difference and form an insertion part; when the fixing sleeve and the bottom plate are assembled, the insertion part is inserted into the cavity and abuts with the inner cavity wall of the cavity.

[0021] As can be seen from the above, the insertion of a part of the fixing sleeve into the cavity can improve the connection strength between the fixing sleeve and the bottom plate, so as to better support and limit the compressor, and also improve the structural strength of the fixing sleeve and the bottom plate.

[0022] A further embodiment is that when the first connecting part is clamped with the second connecting part: the number of the first connecting part is between two and eight, and two or more first connecting parts are evenly distributed at the opening of the cavity; the second connecting part is located at the insertion part, and the number of the second connecting part is less than or equal to that of the first connecting part; when the fixing sleeve and the bottom plate are assembled, each second connecting part can be inserted into the cavity from a first gap, and one second connecting part can be rotated to be clamped with one first connecting part.

[0023] Another further embodiment is that when the first connecting part is screwed with the second connecting part: the first connecting part is an internal thread arranged on the inner cavity wall of the cavity, and the second connecting part is an external thread arranged on the outer periphery of the insertion part.

[0024] As can be seen from the above, the design can reliably connect the fixing sleeve and the bottom plate, and facilitate quick assembly and disassembly of the two.

[0025] A further embodiment is that the bottom wall of the cavity is provided with a drainage hole and a drainage groove, the drainage hole is located at the lowest part of the cavity and penetrates the bottom plate, and the drainage groove is in communication with the drainage hole.

[0026] As can be seen from the above, the arrangement of the drainage hole and the drainage groove can make the water droplets condensed from water vapor flow out of the bottom plate through the drainage groove and the drainage hole, so as to ensure the dryness of the compressor and avoid the water vapor entering the compressor to cause quality problems.

[0027] Further, the bottom plate is provided with a first positioning part, and the first positioning part is a second gap or a first direction mark.

[0028] As can be seen, the first positioning part is used to quickly identify the installation and cooperation position when the bottom plate assembly cooperates with other packaging assemblies (such as a cover plate assembly), so as to ensure that the bottom plate assembly cooperates with other packaging assemblies at an accurate position and reliably fixes the compressor.

[0029] Further, the bottom plate is made of polypropylene or high-density polyethylene; and / or the fixing sleeve is made of polypropylene or high-density polyethylene.

[0030] As can be seen, 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 high toughness, thereby effectively reducing transportation loss, improving recycling rate, and further reducing packaging cost.

[0031] In order to achieve the second object of the application, the application provides a packaging structure, which comprises a cover plate assembly, and the cover plate assembly comprises a cover plate, and a sleeve part is formed on the cover plate, wherein the packaging structure further comprises the above-mentioned bottom plate assembly, and the sleeve part, the cavity, the positioning cavity and the support groove form a fixing position.

[0032] As can be seen, the packaging structure provided with the above-mentioned bottom plate assembly has the advantages of good support, strong universality and wide application range, which is beneficial to reduce the packaging cost of manufacturers.

[0034] As can be seen, by additionally arranging the relay sleeve, the packaging structure can adapt to compressors of different models and specifications through the relay sleeve, so as to further improve the universality and practicability of the packaging structure and further reduce the packaging cost of manufacturers.

[0035] Another preferred scheme is that the relay sleeve is threadedly connected with the sleeve part; or the relay sleeve is buckle-connected with the sleeve part.

[0036] As can be seen, the above design is beneficial to quickly disassemble and assemble the relay sleeve and the sleeve part.

[0037] Further, when the relay sleeve is threadedly connected with the sleeve part: the sleeve part protrudes from the bottom of the cover plate, the outer periphery of the sleeve part is provided with external threads, and the inner circle of the relay sleeve is provided with internal threads; or the inner circle of the sleeve part is provided with internal threads, and the outer periphery of the relay sleeve is provided with external threads.

[0040] From the above, the pressing plate can avoid the later packaging belt extruding the cover plate, thereby protecting the cover plate and enabling the cover plate to be recycled to reduce the packaging cost; the design of the included angle between the top surface and the side surface of the pressing plate can improve the pressure bearing capacity of the pressing plate, avoid the bending of the packaging edge due to uneven stress under the extrusion of the packaging belt, and reduce the damage risk of the compressor; the design of the cover plate can improve the pressure bearing capacity of the cover plate, avoid the bending of the packaging edge due to uneven stress under the extrusion of the packaging belt or the pressing plate, and reduce the damage risk of the compressor.

[0041] Further, the cover plate is provided with a second positioning part, and the second positioning part is a third notch or a second direction mark.

[0042] From the above, the design enables the cover plate assembly and the bottom plate assembly to quickly identify the installation and cooperation position between the components when the compressor is packaged, thereby ensuring the accurate cooperation position of the components and reliably fixing the compressor.

[0043] Further, the cover plate is made of polypropylene or high-density polyethylene; and / or the relay sleeve is made of polypropylene or high-density polyethylene.

[0044] From the above, the design can improve the chemical stability of the cover plate assembly, and the bottom plate assembly has the advantages of high strength and high toughness, thereby effectively reducing the transportation loss, improving the recycling rate, and further reducing the packaging cost.

[0064] First embodiment of the packaging structure

[0065] The packaging structure 100 provided by the present application can be used to package the compressor 10, so as to facilitate storage and transportation of the compressor 10 and protect the compressor 10. Figure 1 and Figure 2 , comprising a bottom plate assembly 1, a cover plate assembly 2 and a pressing plate 3.

[0066] In combination Figure 3 , the bottom plate assembly 1 comprises a bottom plate 11 and a fixing sleeve 12. The fixing sleeve 12 is detachably connected with the bottom plate 11, and the installation 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.

[0067] In combination Figure 4 and Figure 5 , the bottom plate 11 is provided with a cavity 111 for accommodating the bottom of the body of the compressor 10. The number of the cavities 111 is preferably more than two, so as to package more than two compressors 10, realize batch packaging of the compressors 10, and also facilitate reduction of packaging cost. 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 support surface of the cavity 111 for the bottom of the body of the compressor 10 can be provided as a spherical cap surface or a plane according to the shape of the bottom surface of the body of the compressor 10. In the present embodiment, the support surface of the cavity 111 for the bottom of the body of the compressor 10 is a spherical cap surface.

[0068] The bottom wall 122 of the cavity 111 is provided with a drain hole 1111 and a drain groove 1112. The drain hole 1111 is located at the lowest part of the support surface of the cavity 111 for supporting the compressor 10, and penetrates the bottom plate 11 in the thickness direction of the bottom plate 11. The drain groove 1112 is recessed from the aforementioned support surface to the bottom of the bottom plate 11, and extends from the side wall of the cavity 111 to the drain hole 1111 and communicates with the drain hole 1111. By providing the drain hole 1111 and the drain groove 1112 in the cavity 111, water droplets condensed from water vapor can be discharged out of the bottom plate 11 through the drain groove 1112 and the drain hole 1111, so as to ensure drying of the compressor 10 and avoid water vapor entering the compressor 10 to cause quality problems. The number of the drain grooves 1112 is preferably two to four, which are preferably uniformly distributed along the circumference of the cavity 111. The depth of the drain groove 1112 is preferably between 5 mm and 10 mm, so as to ensure that water can flow to the drain hole 1111 through the drain groove 1112. The diameter of the drain hole 1111 is preferably between 10 mm and 20 mm, so as to ensure that water can be discharged out of the cavity 111 through the drain hole 1111.

[0069] In combination Figure 5The bottom plate 11 is further formed with a first connecting part 112 and a positioning slot 113, which are used to connect with the fixing sleeve 12, so that the fixing sleeve 12 can be firmly installed on the bottom plate 11 and kept at a set installation angle position, thereby ensuring the reliability of the fixed packaged compressor 10.

[0070] In combination Figure 6 The fixing sleeve 12 has a side wall 121, which surrounds a positioning cavity 1211 and two or more support grooves 1212 for accommodating and limiting the support 101 on the compressor 10. The two or more support grooves 1212 are distributed around the positioning cavity 1211. In addition, the fixing sleeve 12 is formed with a second connecting part 1213 and a positioning buckle 1221. When the fixing sleeve 12 is assembled with the bottom plate 11, the second connecting part 1213 is detachably connected with the first connecting part 112, one positioning buckle 1221 is connected with one positioning slot 113, and the positioning cavity 1211 is communicated with the cavity 111; wherein the inner cavity wall of the positioning cavity 1211 is cylindrical, and the inner cavity wall of the cavity 111 is also cylindrical, so that when the fixing sleeve 12 is assembled on the bottom plate 11, the inner cavity wall of the positioning cavity 1211 and the inner cavity wall of the cavity 111 are substantially coaxially arranged. In addition, the number of support grooves 1212 can be adjusted according to the number of supports 101 on the packaged compressor 10; usually, the number of support grooves 1212 is between two and four, and the two to four support grooves 1212 are evenly distributed around the positioning cavity 1211; as in the embodiment, the number of support grooves 1212 is three.

[0071] Preferably, the bottom of the support groove 1212 and the bottom of the positioning cavity 1211 have a height difference and form an insertion part 120; when the fixing sleeve 12 is assembled with the bottom plate 11, the insertion part 120 is inserted into the cavity 111 and abuts with the inner cavity wall of the cavity 111. By inserting a part of the installed fixing sleeve 12 into the cavity 111, the connection strength between the fixing sleeve 12 and the bottom plate 11 can be improved, so as to better support and limit the compressor 10, and also help to improve the structural strength of the fixing sleeve 12 and the bottom plate 11.

[0072] In addition, in the embodiment, the second connecting portion 1213 of the fixing sleeve 12 and the first connecting portion 112 on the bottom plate 11 are preferably connected by a snap connection; wherein the number of the first connecting portion 112 and the number of the second connecting portion 1213 are preferably adapted to the number of the bracket groove 1212, that is, the number of the first connecting portion 112 and the number of the second connecting portion 1213 are preferably between two and eight, more than two first connecting portions 112 are uniformly distributed along the circumference of the cavity 111, and more than two second connecting portions 1213 are uniformly distributed along the circumference of the positioning cavity 1211, and more preferably, the number of the first connecting portion 112 and the number of the second connecting portion 1213 are both twice the number of the bracket groove 1212; in the embodiment, the first connecting portion 112 and the second connecting portion 1213 are both six; of course, the number of the second connecting portion 1213 can also be less than the number of the first connecting portion 112.

[0073] The first connecting portion 112 is preferably in a first hook shape, and the second connecting portion 1213 is in a second hook shape cooperating with the first hook shape, so that when the first connecting portion 112 and the second connecting portion 1213 are connected, the first connecting portion 112 and the second connecting portion 1213 are hooked together to improve the firmness of the connection between the fixing sleeve 12 and the bottom plate 11. Among them, the two adjacent first connecting portions 112 form a first gap 1121, so that the second connecting portion 1213 passes through and enters the cavity 111, and the second connecting portion 1213 is located at the insertion portion 120, so that the structure of the fixing sleeve 12 is more optimized and reasonable. When the fixing sleeve 12 and the bottom plate 11 are assembled, each second connecting portion 1213 is inserted into the cavity 111 from a first gap 1121, and then the fixing sleeve 12 is adjusted to the desired installation angle position by rotating, so that one second connecting portion 1213 is rotated to be connected with one first connecting portion 112.

[0074] The number of the positioning groove 113 on the bottom plate 11 is more than two, and more preferably, the number of the positioning groove 113 is between two and eight, and the more than two positioning grooves 113 are preferably uniformly distributed around the cavity 111. The number of the positioning buckle 1221 on the fixing sleeve 12 can be equal to the number of the positioning groove 113, or can be less than the number of the positioning groove 113, and more preferably, the number of the positioning groove 113 is an integer multiple of the number of the positioning buckle 1221, but each positioning buckle 1221 can be connected with a positioning groove 113, such as in the embodiment, the number of the positioning groove 113 is six, and the number of the positioning buckle 1221 is three.

[0075] As Figure 6As shown, the fixing sleeve 12 preferably has a bottom wall 122 at the bottom of each support groove 1212, and the positioning buckle 1221 is preferably formed on the bottom wall 122; more 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 shape, and the arc shape is concentric with the cavity 111, so that the structure of the fixing sleeve 12 and the base plate 11 is more reasonable, and it is also convenient for the positioning buckle 1221 to be engaged in the positioning groove 113. The bottom wall 122 can increase the structural strength of the fixing sleeve 12, avoid deformation of the fixing sleeve 12 under stress and / or reduce the probability of cracking of the fixing sleeve 12; in addition, based on the surrounding support of the compressor body by the positioning cavity 1211, the bottom wall 122 can also reduce the thickness of the base plate 11, thereby reducing the weight of the base 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, so as to complete the adjustment of the installation angle position of the fixed sleeve 12.

[0076] Furthermore, 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 protecting the fixing sleeve 12. Further, a limiting gap 12221 is formed between the support boss 1222 and the side wall 121. Since the bracket 101 of part of the compressor 10 is inverted "U" shape, by forming a limiting gap 12221 between the support boss 1222 and the side wall 121, the bracket 101 of the compressor 10 can be further limited and fixed.

[0077] By setting the fixed sleeve 12 to cooperate with the base plate 11, the positioning cavity 1211 of the fixed sleeve 12 can surround and support the body of the compressor 10, while the bracket groove 1212 of the positioning sleeve can be used to limit and surround the support 101 of the compressor 10, thereby reducing the risk of the compressor 10 tipping over. In addition, by adjusting the positioning buckle 1221 on the fixed sleeve 12 and the engagement connection between different positioning grooves 113, the installation angle position between the fixed sleeve 12 and the base plate 11 can be adjusted, thereby adjusting the placement angle position of the compressor 10 on the base plate 11. This effectively improves the versatility of the base plate assembly 1, expands the application range of the base plate assembly 1, and also reduces the packaging costs for manufacturers.

[0078] Combination Figure 7 The cover plate assembly 2 includes a cover plate 21 and a relay sleeve 22. Combined Figure 8The sleeve part 211 is formed on the cover plate 21, and the number of the sleeve part 211 is preferably two or more, and the two or more sleeve parts 211 correspond to the two or more cavities 111 on the bottom plate 11 one by one, so that a fixing position is formed between one sleeve part 211, one corresponding cavity 111 on the bottom plate 11, the positioning cavity 1211 and the support groove 1212 of the fixing sleeve 12 matched with the cavity 111, and the fixing position is used to support and fix the compressor 10.

[0079] In combination Figure 9 The number of the relay sleeve 22 is preferably two or more, and the two or more relay sleeves 22 correspond to the two or more sleeve parts 211 one by one; one relay sleeve 22 is detachably connected with one 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, the relay sleeve 22, the sleeve part 211, one corresponding cavity 111 on the bottom plate 11, the positioning cavity 1211 and the support groove 1212 of the fixing sleeve 12 matched with the cavity 111 form a fixing position.

[0080] The detachable connection between the relay sleeve 22 and the sleeve part 211 can be threaded connection or buckle connection. In this embodiment, the connection between the relay sleeve 22 and the sleeve part 211 is threaded connection. Specifically, in this embodiment, the sleeve part 211 protrudes from the bottom of the cover plate 21 (i.e. the sleeve part 211 protrudes towards the bottom plate 11), the outer periphery of the sleeve part 211 is provided with an external thread 2111, and the inner circle of the relay sleeve 22 is provided with an internal thread 221. When the relay sleeve 22 is assembled with the sleeve part 211, the relay sleeve 22 is sleeved on the sleeve part 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 part 211 adjustable, and the adjustment is convenient and easy to operate.

[0081] The setting 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 manufacturers. For example, when the body diameter of the compressor 10 is small and / or the upper cover height is low, the relay sleeve 22 can be fixed on the sleeve part 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 part 211; when the body diameter of the compressor 10 is large and / or the upper cover height 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 less than the distance between the bottom of the sleeve part 211 and the bottom plate 11, so that the relay sleeve 22 is still fixed on the sleeve part 211 and participates in the packaging of the compressor 10, to form a fixed cavity with higher height and 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 groove 222 is preferably arranged at the bottom of the relay sleeve 22 to limit and fix the top of the compressor 10.

[0082] In addition, the height of the relay sleeve 22 is between 30 mm and 60 mm, which can ensure that the relay sleeve 22 and the sleeve part 211 have a stable connection structure, can effectively position and support the top of the compressor 10, can ensure the structural strength of the relay sleeve 22, and can avoid the relay sleeve 22 from occupying space due to being too high, thereby facilitating the storage and transportation of the packaging product using the packaging structure 100.

[0083] In the embodiment, the sleeve part 211 preferably extends out of the main body of the bottom plate 11, therefore, in order to increase the structural strength of the main body of the bottom plate 11 and the structural strength between the sleeve part 211 and the main body of the bottom plate 11, a reinforcing rib 213 is arranged on the main body of the bottom plate 11 and between the main body of the bottom plate 11 and the sleeve part 211.

[0084] In combination with Figure 10The pressing plate 3 is substantially in the shape of an inverted truncated pyramid; the pressing plate 3 comprises a plurality of pressing strips 31 arranged side by side, the plurality of pressing strips 31 are closely arranged, and the plurality of pressing strips 31 are arranged in the shape of an inverted truncated pyramid; preferably, the pressing plate 3 further comprises two or more fixing strips 32, the distribution direction of the two or more fixing strips 32 is perpendicular to the distribution direction of the plurality of pressing strips 31, and the fixing strips 32 are perpendicular to the pressing strips 31. The two adjacent fixing strips 32 preferably have a spacing to reduce the weight of the pressing plate 3. The fixing strips 32 can be used to improve the overall structural strength of the pressing plate 3, and can also be used to connect the plurality of pressing strips 31. The pressing plate 3 can avoid the later packaging belt from extruding the cover plate 21, thereby protecting the cover plate 21, so that the cover plate 21 can be recycled to reduce the packaging cost.

[0085] Further, the included 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 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 of the pressing plate 3 due to uneven stress under the extrusion of the packaging belt, thereby reducing the risk of damage to the compressor 10

[0086] Preferably, the pressing strips 31 and the fixing strips 32 are both wooden plates; the bottom plate 11 is preferably made of polypropylene or high-density polyethylene, and the fixing sleeve 12 is preferably made of polypropylene (PP) or high-density polyethylene, 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 high toughness, thereby effectively reducing transportation loss, improving recycling rate, and further reducing packaging cost; 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 high toughness, thereby effectively reducing transportation loss, improving recycling rate, and further reducing packaging cost.

[0087] In addition, the first positioning part 114 is preferably a second notch on the bottom plate 11, and the second positioning part 212 is preferably a third notch on the cover plate 21; this design enables the cover plate assembly 2 and the bottom plate assembly 1 to quickly identify the installation and cooperation position between the components when packaging the compressor 10, thereby ensuring the accurate cooperation position of the components and reliably fixing the compressor 10. Of course, other optional solutions, in other embodiments, the first positioning part 114 can also be a first direction mark; similarly, the second positioning part 212 can be a second direction mark.

[0088] Preferably, the packaging structure 100 can further comprise at least one set of relay assembly, which comprises a partition, a fixed sleeve 12 (consistent with the structure of the fixed sleeve 12 of the bottom plate assembly 1) and a relay sleeve 22 (consistent with the structure of the relay sleeve 22 of the cover plate assembly 2); wherein the top surface of the partition is provided with a cavity 111, a first connecting part 112 and a positioning groove 113 (consistent with the structure of the cavity 111, the first connecting part 112 and the positioning groove 113 on the bottom plate 11), and the bottom surface of the partition is provided with a sleeve part 211 (consistent with the structure of the sleeve part 211 on the cover plate 21). The relay assembly enables the packaging structure 100 to better package the compressors 10 in multiple layers, and ensures the stability of the multiple layers of compressors 10.

[0089] As can be seen from the above, through the design of the packaging structure 100 of the present application, the packaging structure 100 can package more types of compatible compressors 10, improve packaging universality, and reduce packaging cost; at the same time, under the premise of ensuring packaging stability, the packaging material is selected to be a plastic material (such as polypropylene or high-density polyethylene) with higher hardness strength, which has good chemical stability, wear resistance, high recycling rate, and can withstand increased stress, thereby further improving the packaging strength and further improving the transportation loss to reduce pollution and save cost; in addition, the structural design of the pressing plate 3 makes the stress more concentrated and uniform, avoiding the risk of deformation of the packaging edge.

[0090] Packaging structure second embodiment

[0091] Referring to Figure 11 and Figure 12 The difference between the present embodiment and the first embodiment of the packaging structure is the connection structure of the first connecting part and the second connecting part. In the present embodiment:

[0092] Instead of the snap connection assembly mode between the first connecting part 411 and the second connecting part 421, a threaded connection assembly mode is adopted, specifically:

[0093] The first connecting part 411 is an internal thread provided on the inner cavity wall of the cavity 40, and the second connecting 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 can reliably connect the fixed sleeve 42 and the bottom plate 41, and also facilitates quick disassembly and assembly of the two.

[0094] The rest of the structure of the present embodiment is the same as that of the above-mentioned first embodiment of the packaging structure, and therefore will not be repeated here.

[0095] Packaging structure third embodiment

[0096] Referring to Figures 13 to 16The difference between the embodiment and the above-mentioned embodiments is the structure of the cover plate assembly. Specifically, in the embodiment:

[0097] The sleeve part 511 of the cover plate 51 is no longer protruding from the cover plate 51 but is embedded in the cover plate 51. Since the sleeve part 511 is no longer protruding from the cover plate 51, the sleeve part 511 no longer has an outer peripheral wall. In order to adapt to the current design of the sleeve part 511, an internal thread 5111 is arranged on the inner peripheral wall of the sleeve part 511. Correspondingly, the relay sleeve 52 no longer has an internal thread on the inner peripheral wall but has an external thread 521 on the outer peripheral wall of the relay sleeve 52.

[0098] When the relay sleeve 52 is assembled with the sleeve part 511, the sleeve part 511 is sleeved on the relay sleeve 52, and the external thread 521 of the relay sleeve 52 is threadedly connected with the internal thread 5111 of the sleeve part 511. When the relay sleeve 52 is not needed to package the compressor 50, the relay sleeve 52 can be screwed into the sleeve part 511 to be hidden or can be detached from the sleeve part 511. When the relay sleeve 52 is needed to package the compressor 50, a part of the relay sleeve 52 is threadedly connected with the sleeve part 511 for a sufficient length, and the other part of the relay sleeve 52 protrudes from the sleeve part 511 to limit and fix the top of the compressor 50.

[0099] Preferably, since the sleeve part 511 is embedded in the cover plate 51, the cover plate 51 can be designed with a hollow part 512 between adjacent sleeve parts 511 to reduce the weight of the cover plate 51, save the material for manufacturing the cover plate 51, and prevent the compressor 50 from being damaged due to excessive pressure applied to the compressor 50 caused by the excessive weight of the cover plate 51. More preferably, the sleeve part 511 penetrates the cover plate 51.

[0100] In addition, the cover plate 51 is in the shape of an inverted truncated pyramid, and the included 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, avoid the bending of the packaging edge caused by uneven stress when the cover plate 51 is pressed by the packaging belt, and thus reduce the risk of damage to the compressor 50. At the same time, based on the design of the cover plate 51 in the shape of an inverted truncated pyramid, the use of a pressing plate can be cancelled when the compressor 50 is packaged, thereby reducing the packaging cost.

[0101] The rest of the structure of the embodiment is the same as that of the first or second packaging structure of the above-mentioned embodiments, and thus is not repeated here.
