TECHNICAL FIELD
[0001] The utility model belongs to the packaging field, concretely relates to a packing box lining and packing box of inverter. BACKGROUND
[0002] The inverter is an auxiliary device for power supply, mainly used for converting direct current into alternating current, and is widely applied to various electric appliances requiring alternating current, such as air conditioners, home theaters, electric tools, computers, televisions and the like. Before the inverter is completed and shipped, it needs to be packaged for convenient transportation,
[0003] At present, the existing inverter packaging box is usually a simple carton structure, or is filled with foam packaging. During long-distance transportation, if the inverter is simply packaged by the carton, when the carton is shaken due to external force, the inverter in the carton is prone to damage due to collision, which may cause fire or explosion risk and economic loss. The foam packaging is prone to breakage due to its brittleness, so that the foam packaging has poor buffering effect and cannot stably protect the inverter when the carton is impacted. SUMMARY
[0004] The technical problem to be solved by the utility model is to provide a packing box lining and packing box of inverter to solve the problem of poor buffering effect of the packaging structure of the inverter.
[0005] To solve the above technical problem, the utility model adopts the following technical scheme: a packing box lining of inverter, comprising a supporting part for abutting against the bottom of the inverter and a buffering part for abutting against the outer circumferential side of the inverter, the supporting part and the buffering part jointly form a packaging groove for accommodating the inverter, and the packing box lining is integrally folded by paperboard to form a double-layer structure with a hollow interlayer. The technical scheme has the following technical effects:
[0006] The packing box lining is integrally folded by paperboard to form a double-layer structure with a hollow interlayer, which can provide space for the deformation of the buffering part. When the inverter is placed in the packaging groove of the packing box lining, if the side of the packing box is impacted and the buffering part is extruded, the outer layer structure of the buffering part deforms towards the hollow interlayer, without colliding with the inner layer structure of the buffering part abutting against the inverter, so as to avoid the impact being transmitted to the inverter and effectively protect the inverter. If the packing box is shaken to drive the inverter to shake left and right and extrude the buffering part, the inner layer structure of the buffering part deforms towards the hollow interlayer to buffer the inverter, so as to avoid the inverter from colliding with external objects due to shaking, thereby avoiding the inverter from being damaged due to collision and causing fire or explosion, and achieving good buffering effect. Since the packing box lining is folded by paperboard, the production and processing difficulty of the packing box lining is reduced, and the packing box lining is more environmentally friendly than the foam packaging.
[0007] In the above-mentioned inner liner of the packaging box of the inverter, the buffer part comprises a ring-shaped connecting plate surrounding a packaging groove slot, a plurality of first buffer plates connected to the inner ring of the ring-shaped connecting plate, and a plurality of second buffer plates connected to the outer ring of the ring-shaped connecting plate, the first buffer plates and the second buffer plates are folded downward to form the buffer part. By horizontally arranging the ring-shaped connecting plate, and then folding the first buffer plates and the second buffer plates downward, the first buffer plates and the second buffer plates are longitudinally extended and arranged in parallel, so that the buffer part with a hollow sandwich is formed, which is simple in structure and convenient for production and processing.
[0008] In the above-mentioned inner liner of the packaging box of the inverter, the support part is provided with a socket, the bottom of the first buffer plate is provided with a plug-in protrusion, and the plug-in protrusion is plugged into the socket to limit the bottom of the first buffer plate. The first buffer plate is kept in a vertical state, so that the first buffer plate can effectively support the inverter, ensuring that the first buffer plate can stably buffer the inverter and avoiding collision damage of the inverter.
[0009] In the above-mentioned inner liner of the packaging box of the inverter, the length of the plug-in protrusion is greater than the depth of the socket, and when the plug-in protrusion is plugged into the socket, the bottom of the plug-in protrusion protrudes out of the socket. When the first buffer plate is impacted by the inverter to bend and deform towards the hollow sandwich, even if the plug-in protrusion moves upward with the first buffer plate by a certain distance, the plug-in protrusion is always plugged into the socket, ensuring the stable plugging of the plug-in protrusion and the socket, and further ensuring the stable buffering of the first buffer plate to the inverter.
[0010] In the above-mentioned inner liner of the packaging box of the inverter, one side of the support part is provided with a limiting plate, and the limiting plate is folded upward to be stacked with the second buffer plate. The limiting plate not only limits the second buffer plate stacked therewith, but also enhances the strength of the second buffer plate stacked therewith, so that the impact resistance of the second buffer plate is better.
[0011] In the above-mentioned inner liner of the packaging box of the inverter, the support part comprises a bottom plate for abutting against the inverter and a support plate connected to the bottom plate, and when the inner liner of the packaging box is arranged in the packaging box, the support plate abuts against the packaging box to form a buffer gap between the bottom plate and the packaging box below the bottom plate. When the bottom of the packaging box is impacted by external force, the buffer gap can reserve a deformation space for the packaging box, so that the packaging box deforms towards the buffer gap without directly contacting the bottom plate, thereby avoiding the inverter abutting against the bottom plate impacted by external force. If the packaging box vibrates to drive the inverter to impact the bottom plate, the bottom plate deforms towards the buffer gap to buffer the inverter, avoiding the inverter from colliding with external objects, thereby avoiding the inverter from being damaged due to collision and causing fire or explosion, and the buffering effect is good.
[0012] In the above-mentioned inner lining of the packaging box of the inverter, the support plate is provided with two, and the two support plates are connected to the two sides of the bottom plate respectively, and the support plate is folded to form a support protrusion protruding from the lower part of the bottom plate. Two support protrusions simultaneously support the two sides of the bottom plate, so that the height of the buffer gap can be kept stable, the structure is simple, the supporting effect is good, and the buffering effect of the buffer gap is good.
[0013] In the above-mentioned inner lining of the packaging box of the inverter, a crease line is arranged on the support plate, and the support plate is bent along the crease line, and the end of the support plate is abutted on the bottom of the bottom plate, so that a cavity is formed in the inside of the support protrusion. The cavity makes the support protrusion have a certain deformation amount, and when the support protrusion is impacted by the inverter or the outside of the packaging box, the cavity can be deformed to achieve buffering.
[0014] The utility model also provides a kind of packaging box of inverter, including box body and the box cover of covering on box body, also include above-mentioned packaging box lining, packaging box lining is set in box body. When packaging, first, the folding completed packaging box lining is placed into box body, then the inverter is placed into the packaging groove of packaging box lining, finally, cover box cover, the packaging of inverter can be completed, structure is simple and reliable.
[0015] In the above-mentioned packaging box of inverter, the height of the packaging box lining is the same as the depth of the box body, when the box cover is covered on the box body, the box cover is abutted with the top of the buffer part, to form covering on the top of the packaging groove. So that the buffer part can support the box cover to a certain extent, when the box cover is impacted by external force, the buffer part can be deformed to the hollow interlayer to offset part of the impact of external force, and the buffering effect is better.
