Description

Technical Field

[0001] This utility model relates to the field of tomato transportation technology, and in particular to a foldable dwarf tomato transport packaging rack. Background Technology

[0002] Currently, dwarf tomatoes are often transported using fixed metal or plastic transport racks, with tiered pallets supporting the tomatoes. Some transport racks will have foam pads or cardboard placed on the pallets for simple protection. Others will pack the tomatoes into cardboard boxes, layer by layer, and then stack them on ordinary shelves for transport.

[0003] During use, the fixed transport rack cannot be folded, and it takes up a lot of space when the rack is empty for return transport or when it is not in use, which greatly increases the storage and transportation costs. At the same time, the cushioning effect of simple protective measures such as foam pads and cardboard is limited and it is difficult to cope with the bumps and impacts during transportation. Tomatoes are still easily damaged by collisions and squeezing, and the dual needs of efficient space utilization and transportation protection cannot be met. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a foldable dwarf tomato transport packaging rack. It connects to a folding plate via a rotating head, and is equipped with a tow bar, a placement platform with vents, an air cushion, and a stable support with a lifting plate. It also adds a protective mechanism with an air pump and a ventilation component with a solenoid valve. The top placement platform can be secured with a sealing cover. This solution achieves folding and storage of the packaging rack through the cooperation of the folding plate and the rotating head, solving the problems of large space occupation and high warehousing and transportation costs associated with existing fixed transport racks. Furthermore, by utilizing the air cushion for cushioning and the air circulation of the ventilation component, it addresses the issues of poor cushioning effect and the ease with which tomatoes are damaged and spoiled due to bumps or excessive heat in existing simple protective measures.

[0006] To achieve the above objectives, this utility model proposes a foldable dwarf tomato transport packaging rack, comprising a support frame, rotating heads, folding plates, a drag bar, a placement platform, an air cushion, and a stabilizing bracket. Two support frames are provided, each with a folding groove on one side. Multiple rotating heads are rotatably connected at equal intervals to the inner wall of the folding groove. One end of the folding plate is fixedly connected to the outer wall of the rotating head. The drag bar is fixedly connected to the inner wall of the folding plate. The bottom ends of the placement platform are engaged with the tops of the drag bar. The air cushion is fixedly connected to the bottom of the placement platform. One end of the stabilizing bracket is engaged with the side wall of the support frame. Multiple lifting plates are fixedly connected at equal intervals to the inner wall of the stabilizing bracket, with the tops of the lifting plates abutting against the bottom of the folding plate.

[0007] This utility model discloses a foldable dwarf tomato transport packaging rack. In use, the folding plate is rotated out of the folding slot of the support frame by rotating the head, engaging the stabilizing bracket, and using its inner wall support plate to support the folding plate. The placement tray is then engaged with the folding plate's support rod and secured with the stabilizing bracket's limiting bolts. After the dwarf tomatoes are placed on the placement tray, a sealing cover is engaged at the top. The protective mechanism's air pump is activated, and gas is injected into the air cushion through the output pipe, connecting hose, and air injection head for cushioning. The ventilation component opens a solenoid valve at regular intervals, allowing the gas in the air cushion to be discharged through the exhaust port of the placement tray via the output head, connecting pipe, and input head for ventilation. When not in use, the folding plate is rotated back into the folding slot for storage. This solution addresses the problems of large space occupation and high warehousing and transportation costs associated with existing fixed transport racks by using the folding plate, rotating head, and folding slot; it solves the problem of poor cushioning effect and easy damage to tomatoes caused by simple protective measures by using an inflatable air cushion; and it solves the problem of tomato spoilage due to stuffy conditions during transport by using the ventilation component and exhaust port.

[0008] In addition, the foldable dwarf tomato transport packaging rack proposed above according to this utility model may also have the following additional technical features: Specifically, it also includes a protective mechanism, which includes a placement plate, an air pump, an output pipe, an air injection head, and a connecting hose. The placement plate is snapped onto the bottom inner wall of the two support frames. The air pump is installed on the top of the placement plate. One end of the output pipe is fixedly connected to the output end of the air pump. The air injection head is installed on the outer wall of the air cushion. The connecting hose is provided between the air injection head and the output pipe, and they are connected through the connecting hose.

[0009] Specifically, it also includes a ventilation assembly, which includes an output head, an input head, a connecting pipe, and a solenoid valve. The output head is fixedly connected to the outer wall of the air cushion, the input head is fixedly connected to the outer wall of the placement platform, the two ends of the connecting pipe are respectively threaded onto the output head and the input head, and the solenoid valve is installed on the input head.

[0010] Specifically, the inner wall of the placement platform is provided with multiple vent holes.

[0011] Specifically, the outer wall of the stabilizing bracket is threaded with multiple limiting bolts at equal intervals, and the end of the placement platform is provided with threaded holes that match the limiting bolts.

[0012] Specifically, the top of the placement platform located at the very top is fitted with a sealing cover.

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The following describes a foldable dwarf tomato transport packaging rack according to an embodiment of the present invention, with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the foldable dwarf tomato transport packaging rack of this utility model embodiment may include a support frame 1, a rotating head 2, a folding plate 3, a drag bar 4, a placement drag table 5, an air cushion 6, and a stabilizing bracket 7.

[0019] Among them, there are two support frames 1. A folding groove 11 is opened on one side of the support frame 1. Multiple rotating heads 2 are rotatably connected to the inner wall of the folding groove 11 at equal intervals. One end of the folding plate 3 is fixedly connected to the outer wall of the rotating head 2.

[0020] It should be noted that the inner wall of the folding groove 11 described in this embodiment can be provided with a wear-resistant layer to reduce the wear caused by repeated contact between the folding plate 3 and the groove wall. At the same time, the outer wall of the folding plate 3 can be smoothed to ensure that it can be smoothly expanded and contracted in the folding groove 11, further improving the convenience of folding operation and the structural durability of the support frame 1 and the folding plate 3.

[0021] The tow bar 4 is fixedly connected to the inner wall of the folding plate 3, the bottom ends of the tow platform 5 are snapped into the top of the tow bar 4, and the air cushion 6 is fixedly connected to the bottom of the tow platform 5.

[0022] It should be noted that the top of the tow bar 4 described in this embodiment may be provided with anti-slip protrusions that are adapted to the bottom of the tow platform 5, which, together with the groove at the bottom of the tow platform 5, form a snap-fit, ensuring that the tow platform 5 is installed firmly and does not slide easily, and is easy to install and remove quickly. At the same time, the air cushion 6 may be made of a flexible and puncture-resistant material, and its connection with the bottom of the tow platform 5 may be achieved by using sealant bonding and edge pressing, ensuring that it fits tightly against the tow platform 5 after inflation, evenly distributing the pressure brought by the weight of the tomato, and improving the cushioning and shock absorption effect of the air cushion 6 on the tow platform 5 and the tomato.

[0023] One end of the stabilizing bracket 7 is snapped into the side wall of the support frame 1. Multiple lifting plates 71 are fixedly connected at equal intervals on the inner wall of the stabilizing bracket 7. The top of the lifting plate 71 abuts against the bottom of the folding plate 3.

[0024] It should be noted that the snap-fit ​​part between the stabilizing bracket 7 and the support frame 1 described in this embodiment can be provided with an elastic buckle, which automatically locks after the stabilizing bracket 7 is snapped into the support frame 1, preventing the stabilizing bracket 7 from falling off due to transportation bumps. In addition, the top of the lifting plate 71 can be covered with an elastic buffer pad, which can enhance the friction when it comes into contact with the bottom of the folding plate 3 to prevent the folding plate 3 and the lifting plate 71 from sliding relative to each other, and can also absorb some vibration through the buffer pad to avoid wear caused by hard contact between the folding plate 3 and the lifting plate 71. At the same time, the contact points between the multiple lifting plates 71 and the folding plate 3 are evenly distributed, which can evenly bear the weight of the folding plate 3 and the platform 5 and tomatoes placed on it, thereby improving the load-bearing stability of the stabilizing bracket 7 for the overall structure.

[0025] Specifically, in use, the folding plate 3 is rotated out of the folding groove 11 of the support frame 1 to a suitable angle by rotating the head 2, and the stabilizing bracket 7 is snapped into the side wall of the support frame 1. The lifting plate 71 on the inner wall of the stabilizing bracket 7 abuts against the bottom of the folding plate 3 to support the folding plate 3. The placement platform 5 is installed by snapping the bottom of both ends of the platform onto the drag bar 4 on the inner wall of the folding plate 3. The air cushion 6 is fixed to the bottom of the placement platform 5 to provide cushioning. The wear-resistant layer on the inner wall of the folding groove 11 and the smooth treatment on the outer wall of the folding plate 3 ensure smooth folding. The anti-slip protrusion on the top of the drag bar 4 cooperates with the groove at the bottom of the placement platform 5 to ensure its stability. The elastic buckle at the snapping part of the stabilizing bracket 7 and the support frame 1 prevents it from falling off. The cushioning pad on the top of the lifting plate 71 reduces wear. When not in use, the folding plate 3 is rotated back into the folding groove 11 by rotating the head 2 to achieve folding and storage. This solution achieves the folding of the packaging rack through the cooperation of the folding plate 3, the rotating head 2, and the folding groove 11. It solves the problem that the existing fixed transport rack cannot be folded and occupies a lot of space, resulting in high warehousing and transportation costs. At the same time, through the cushioning effect of the air cushion 6 and the stable design of the towing rod 4 and the stabilizing bracket 7, it solves the problem that the existing simple protective measures have poor cushioning effect and tomatoes are easily damaged by bumps.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, it also includes a protective mechanism 8, which includes a placement plate 81, an air pump 82, an output pipe 83, an air injection head 84, and a connecting hose 85. The placement plate 81 is snapped onto the bottom inner wall of the two support frames 1. The air pump 82 is installed on the top of the placement plate 81. One end of the output pipe 83 is fixedly connected to the output end of the air pump 82. The air injection head 84 is installed on the outer wall of the air cushion 6. A connecting hose 85 is provided between the air injection head 84 and the output pipe 83, and they are connected through the connecting hose 85.

[0027] It should be noted that the connecting hose 85 described in this embodiment can be made of a flexible and aging-resistant material. Its length can be adapted to the height of the air cushion 6 corresponding to different layers of the placement platform 5, ensuring that the air pump 82 can stably inject air into the air cushion 6 at any position. At the same time, the air pump 82 can integrate a pressure sensing module to monitor the air pressure inside the air cushion 6 in real time, avoiding overcharging that could cause damage to the air cushion 6 or undercharging that could affect the cushioning effect. The bottom of the placement plate 81 can be equipped with an anti-slip rubber pad to enhance its friction with the inner wall of the bottom of the support frame 1, preventing the placement plate 81 from shifting due to the operation of the air pump 82 or the vibration of the frame during transportation, and further improving the overall stability of the protective mechanism 8.

[0028] Specifically, after the placement plate 81 is snapped onto the inner wall of the bottom of the two support frames 1, the air pump 82 on the placement plate 81 is started. The gas generated by the air pump 82 is delivered to the connecting hose 85 through the output pipe 83, and then injected into the air cushion 6 through the air injection head 84, so that the air cushion 6 expands and fits tightly against the bottom of the placement tray 5. During this process, the pressure sensing function of the air pump 82 can ensure that the air cushion 6 maintains a suitable buffering pressure, and the flexibility of the connecting hose 85 ensures that the multiple layers of air cushion 6 can be effectively inflated. This solves the problem that the simple protective measures of foam pads and cardboard have limited buffering effect and cannot cope with the damage to tomatoes caused by bumps and impacts in the background technology. At the same time, the anti-slip design of the placement plate 81 ensures that the air pump 82 operates stably and that the protective mechanism 8 continues to play its role.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, it also includes a ventilation assembly 86, which includes an output head 861, an input head 862, a connecting pipe 863, and a solenoid valve 864. The output head 861 is fixedly connected to the outer wall of the air cushion 6, the input head 862 is fixedly connected to the outer wall of the placement platform 5, the two ends of the connecting pipe 863 are respectively threaded onto the output head 861 and the input head 862, and the solenoid valve 864 is installed on the input head 862.

[0030] It should be noted that the connecting pipe 863 described in this embodiment can be made of food-grade sealing material. Sealing tape can be wrapped around the threaded connections at both ends of the pipe to the output head 861 and the input head 862 to prevent gas leakage from affecting the ventilation effect. The solenoid valve 864 can be connected to a timer control module to set the ventilation interval and duration according to the storage requirements of dwarf tomatoes, without the need for frequent manual operation. At the same time, the connection between the input head 862 and the placement tray 5 is reinforced by welding to prevent the input head 862 from falling off after long-term use, which would cause the ventilation component 86 to fail.

[0031] Specifically, when ventilation is needed for the tomatoes placed on the tray 5, the solenoid valve 864 installed on the input head 862 is opened. The gas in the air cushion 6 enters the input head 862 through the output head 861 and the connecting pipe 863 in sequence, and finally exits from the exhaust hole on the inner wall of the tray 5, forming a gas circulation. The sealing design of the connecting pipe 863 ensures efficient gas delivery, and the timed control of the solenoid valve 864 realizes automated ventilation. This component, together with the exhaust hole of the tray 5, solves the problem of tomatoes easily spoiling due to the hot and humid environment during transportation in the background technology. At the same time, the gas circulation process can also remove some of the heat generated by the tomatoes' respiration, further ensuring the freshness of the tomatoes.

[0032] It should be understood that the solenoid valve 864 opens intermittently, not continuously, thus ensuring that the air cushion 6 provides stable protection for the tomatoes below.

[0033] In one embodiment of this utility model, such as Figures 1-4As shown, the inner wall of the platform 5 is provided with multiple vent holes.

[0034] It should be noted that the multiple vent holes on the inner wall of the placement tray 5 described in this embodiment can be evenly distributed in a matrix to ensure that tomatoes at each position on the placement tray 5 can come into contact with circulating gas, avoiding local ventilation dead zones. The diameter of the vent holes can be set to be smaller than the minimum diameter of dwarf tomatoes to prevent tomatoes from falling out of the vent holes during transportation. At the same time, the inner wall of the vent holes can be smoothly polished to avoid generating large noise when the airflow passes through, and also to prevent residual impurities on the hole wall from contaminating the tomatoes.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, the outer wall of the stabilizing bracket 7 is threaded with multiple limit bolts 72 at equal intervals, and the end of the platform 5 is provided with threaded holes that match the limit bolts 72.

[0036] It should be noted that the limiting bolt 72 described in this embodiment can be made of stainless steel, which has good rust resistance, adapts to the humid environment that may be encountered during transportation, and extends service life. The fit between the limiting bolt 72 and the screw hole at the end of the placement platform 5 can adopt a fine thread design to enhance the tightness of the threaded connection and prevent the bolt from loosening due to long-term bumps. At the same time, the head of the limiting bolt 72 can be provided with anti-slip texture, which is convenient for manual tightening operation and can be fixed and disassembled without additional tools.

[0037] It should be understood that the top of the topmost placement platform 5 is fitted with a sealing cover.

[0038] In summary, the foldable dwarf tomato transport packaging rack of this utility model embodiment is used by rotating the head 2 to rotate the folding plate 3 out of the folding groove 11 of the support frame 1, engaging the stabilizing bracket 7 and using its inner wall support plate 71 to support the folding plate 3, engaging the placement tray 5 on the drag bar 4 of the folding plate 3, and fixing the placement tray 5 with the limiting bolt 72 of the stabilizing bracket 7. After the dwarf tomatoes are placed on the placement tray 5, the sealing cover is engaged at the top. The air pump 82 of the protective mechanism 8 is started, and the gas is injected into the air cushion 6 through the output pipe 83, the connecting hose 85, and the air injection head 84 to achieve buffering. The ventilation component 86 opens the solenoid valve 864 at timed intervals, so that the gas in the air cushion 6 is discharged from the exhaust hole of the placement tray 5 through the output head 861, the connecting pipe 863, and the input head 862 for ventilation. When not in use, the folding plate 3 is rotated back into the folding groove 11 for storage. This solution addresses the problems of large space occupation and high warehousing and transportation costs associated with existing fixed transport racks by using the folding plate 3 in conjunction with the rotating head 2 and the folding groove 11. It also solves the problem of poor cushioning effect and easy damage to tomatoes caused by simple protective measures by using the air cushion 6 for cushioning. Finally, it solves the problem of tomatoes spoiling due to stuffy conditions during transportation by using the ventilation component 86 in conjunction with the exhaust vent.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
