In order to solve the above problems, referring to fig. 1 and 2, an embodiment of the present application provides a package base, including: the device comprises a supporting plate component 1, a buffer block component 3 and a fixing strip component 2, wherein the buffer block component 3 and the fixing strip component 2 are arranged on the supporting plate component 1, the supporting plate component 1 is a medium density fiberboard and/or a hard fiberboard, the buffer block component 3 is made of buffer plastic and/or rubber, the buffer block component 3 comprises a first angle buffer block 301 and a second angle buffer block 302, the fixing strip component 2 comprises a transverse fixing strip 402 and a longitudinal fixing strip 401, and the two first angle buffer blocks 301 are connected through the transverse fixing strip 402; the two second corner buffer blocks 302 are connected through a transverse fixing strip 402, the first corner buffer block 301 is connected with the second corner buffer blocks 302 through a longitudinal fixing strip 401, a first fixing groove 3011 is formed in the first corner buffer block 301 and used for fixing supporting feet of a refrigerator, a second fixing groove 3021 is formed in the second corner buffer blocks 302 and used for fixing a compressor support of the refrigerator.

In some embodiments, the support plate assembly 1 comprises a support plate 101, the support plate 101 being a medium density fiberboard and a hard fiberboard, the medium density fiberboard having a density of 0.4-0.8g/cm ³ The density of the hard fiber board was 0.8g/cm ³ . The medium-density fiberboard has uniform internal structure, moderate density, good dimensional stability and small deformation, and can reduce the deformation phenomenon of the supporting plate component 1 caused by the overlarge weight or the overlarge size of the refrigerator; in addition, the medium density fiberboard has a larger width, the thickness of the board can be changed within the range of 2.5-35 mm, the thickness of the supporting board assembly 1 can be selected according to different requirements, in the embodiment, the thickness of the supporting board assembly 1 is 3-10mm, the thickness can be selected according to the size and the weight of the refrigerator, and the thickness of the supporting board 101 can be selected as 10mm for the refrigerator with a heavier size.

If the refrigerator packaged by the packaging base is a large-volume refrigerator, the refrigerator is larger in size and heavier in weight, at the moment, the hard fiberboard can be selected as the supporting plate 101, the hard fiberboard has the characteristics of high density, high strength, difficult expansion, deformation and the like, and the high-strength characteristic of the hard fiberboard can provide a better supporting effect for the refrigerator, so that the falling probability of the refrigerator is reduced. In addition, the hard fiber board also has the characteristics of moisture resistance, antibacterial property, corrosion resistance and the like, and the probability of mildew of the package base can be reduced when the hard fiber board is stored for a long time or in a wet place.

Due to the relative positions of the two support feet of the refrigerator, in some embodiments, the two first corner buffer blocks 301 are symmetrically disposed.

Because the supporting leg needs to be fixed, a first fixing groove 3011 can be formed on the first corner buffer block 301, wherein the first fixing groove 3011 is a cylindrical stepped groove or the first fixing groove 3011 is a cylindrical groove, and a buckle is arranged in the first fixing groove 3011 and used for fixing the supporting leg of the refrigerator. Because the refrigerator supporting legs have different shapes, when the cross section of the supporting legs is T-shaped, the supporting legs can be placed in the cylindrical stepped grooves, when the supporting legs are universal wheels or cylindrical supporting legs, the supporting legs can be placed in the cylindrical grooves, and the refrigerator supporting legs are rotatable, so that the refrigerator supporting legs are more firm in packaging, and when the supporting legs are universal wheels, other fixing grooves can be formed in the first corner buffer blocks 301 for independently placing the universal wheel supporting legs. After the supporting legs are placed in the first fixing grooves 3011, the supporting legs can be bound through the buckles, so that the connection between the package base and the refrigerator is more stable.

Referring to fig. 3, in some embodiments, the second fixing groove 3021 includes a clamping plate having a C-shaped structure. Other clamping plates can be arranged according to requirements due to different shapes of compressor supports of different refrigerators. To accommodate the compressor rack of different shapes, the clamping plate is detachably connected with the second fixing groove 3021.

In order to reduce the sliding of the refrigerator on the first fixing groove 3011 and the second fixing groove 3021, fixing blocks can be arranged on the inner wall of the first fixing groove 3011 and the surface of the second fixing groove 3021, wherein the fixing blocks can be made of rubber or mineral fibers, and the rubber has strong toughness and elasticity and can improve the friction coefficient between the refrigerator and the packaging base; the mineral fiber has extremely high wear resistance and corrosion resistance, can bear high-strength friction force and friction heat in the friction process, and is not easy to break or fall off. And further, the connection between the supporting legs of the refrigerator and the compressor bracket and the first and second fixing grooves 3011 and 3021 is more stable.

To increase the utilization of the package base, the first corner bumper 301 and the second corner bumper 302 also use non-EPS materials, and in some embodiments, the cushioning Plastic is one or more of EPP (Expanded polypropylene ) Plastic, EPE (Expandable Polyethylene, polyethylene foam) Plastic, EVA (Ethylene Vinyl Acetate Copolymer, ethylene-vinyl acetate copolymer) Plastic, and the Rubber material is one or more of TPR (thermoplastic-Rubber), TPV (Thermoplastic Vulcanizate ).

The EPP plastic is an environment-friendly degradable material, and can degrade the used EPP material, so that the harm to the environment is reduced. Moreover, EPP is a closed-cell structural material, has rebound resilience, and can effectively buffer pressure received from the outside so as to reduce damage to the refrigerator.

EPE plastic can also keep good toughness and elasticity without brittle fracture when the ambient temperature is higher, and can keep soft and not become hard when the ambient temperature is lower. Moreover, the EPE plastic has good hydrolysis resistance and is not easy to be decomposed by water molecules, so that the EPE plastic can be used for a long time, and does not volatilize any harmful substances, so that the EPE plastic does not pollute the environment. EPE plastics also have good resistance to uv light and are not prone to ageing. EPE plastics are also well-tolerated by a wide variety of chemicals and do not deteriorate by exposure to chemicals.

EVA plastic has good elasticity, and can effectively reduce the impact of the outside on the refrigerator. EVA plastic has good wear resistance, can withstand long-time use and friction, and is not easy to damage. EVA plastic has good chemical corrosion resistance and can prevent corrosion from chemical substances. EVA plastic also has good waterproof performance, and can effectively prevent moisture penetration.

In the actual use process, the materials of the first corner buffer block 301 and the second corner buffer block 302 can be selected according to the environment and the requirement of the transport refrigerator, and for example, because the second corner buffer block 302 is connected with the compressor bracket, in order to keep the second corner buffer block 302 in a relatively dry environment, the second corner buffer block 302 can be made of EVA plastic, and the EVA plastic has good waterproof performance and can be timely processed after the second corner buffer block 302 is found to have moisture. Again by way of example, since the first corner bumper 301 is in contact with the support foot, there may be a bump, the first corner bumper 301 may be selected from SPP plastic, which is resilient and may reduce damage due to a bump with the support foot. When the transportation environment is winter, EPE plastic can be selected as the materials of the first corner buffer block 301 and the second corner buffer block 302, and when the environment temperature is low, the EPE plastic can be soft and cannot become hard, so that the refrigerator can be better protected.

In some embodiments, the first corner bumper 301 and the second corner bumper 302 have a thickness of 30-60mm, for example: the length of the first corner buffer block 301 may be set according to the length of the support leg of the refrigerator to maintain the refrigerator in balance.

In some embodiments, the transverse fixing strips 402 and the longitudinal fixing strips 401 are one or more of honeycomb paperboard and corrugated paperboard, and the heights of the transverse fixing strips 402 and the longitudinal fixing strips 401 are lower than the first corner buffer blocks 3012-10mm. The honeycomb paperboard has a flat surface and is not easy to deform, and can provide better support for the first corner buffer block 301 and the second corner buffer block 302. And the shock resistance and the buffer property are good, the side edge of the refrigerator can be well protected, and the refrigerator is not easy to damage. The honeycomb paperboard is made of recyclable paper, has no pollution and can be recycled. The corrugated board has good buffering performance: because the corrugated board has a special structure, 60-70% of the volume in the board structure is empty, so the corrugated board has good damping performance, and the impact of the refrigerator can be effectively reduced. In addition, no pollutant and chemical substance are discharged in the manufacturing process of the corrugated board, the material can be recycled, and the influence on the environment is small. The honeycomb paper board and the corrugated paper board can be recycled, so that the utilization rate of the package base is increased. The transverse fixing bars 402 and the longitudinal fixing bars 401 of different widths are provided according to the shapes of the refrigerator supporting legs and the compressor bracket.

Wherein, the stretching plate is located the intermediate position of backup pad 101, and the stretching plate divide into first end and second end with backup pad 101, and first end and second end are connected the first end and the second end of another backup pad 101 respectively, and first end, second end are equipped with stretching groove with the position that other connecting plates are not connected, and stretching plate can stretch out and draw back in stretching groove to reach the effect of extension and/or widening package base, just can be adjusted in a flexible way through the refrigerator of equidimension, in order to improve package base's utilization ratio from the on the other hand.

Specifically, in some embodiments, the stretching plate includes fixed plate and movable plate, is equipped with the connecting hole on the fixed plate, and two movable plates pass through the threaded rod and connect, and the surface of threaded rod is equipped with the external screw thread, is equipped with the internal screw thread in the connecting hole, and external screw thread and internal screw thread meshing still are equipped with the swivel becket on the threaded rod, and the swivel becket is used for controlling the relative position of movable plate and fixed plate. Illustratively, when it is desired to extend the package base, the rotating ring is rotated clockwise to gradually distance the external threads from the internal threads, i.e., by increasing the length of the threaded rod and the fixed plate, to extend the package base. Again, by way of example, when it is desired to widen the package base, the position of the fixed and movable plates below the longitudinal fixing bar 401 is similarly extended to widen the package base.

After fixed completion of packing base and refrigerator, in order to be convenient for remove the package subassembly, in some embodiments, still include the removal subassembly, remove the subassembly and keep away from the backup pad subassembly 1 of buffer block subassembly 3 and dismantle and be connected, remove the subassembly and include connecting plate, fixed foot and spring, the fixed plate is connected to the one end of spring, the fixed foot is connected to the other end of spring, is equipped with fixed knot on the connecting plate, fixed knot and backup pad 101 joint.
