Description

Technical Field

[0001] This utility model belongs to the field of storage racks, specifically relating to a multi-layer trolley with interlayer leak prevention. Background Technology

[0002] Storage trolleys typically feature multiple storage trays to increase storage capacity, save space, and improve handling efficiency. However, these trolleys present significant drawbacks when used to carry containers containing liquids. Accidental bumps or jolting during movement can cause containers to shake or even tip over, easily spilling liquid onto the trays. If the trays lack drainage holes, spilled liquid remains, leading to prolonged contact with other containers on that tray, severely impacting container cleanliness and making the trays difficult to clean. If the trays have drainage holes, spilled liquid from the upper trays can drip onto the ground or lower trays, contaminating lower items. Even with lids, drips onto lids can contaminate the openings and, consequently, the contents. Therefore, it is necessary to isolate different liquids between the upper and lower layers of the trolley to prevent interlayer leakage and contamination. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a multi-layer trolley with interlayer leakage prevention. When liquid is spilled on the upper storage tray, it can guide the liquid to the bottom of the trolley for collection, preventing the liquid from dripping onto the lower storage tray and causing contamination of items, thereby improving the cleanliness of the surrounding environment.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A multi-layer leak-proof trolley includes a frame-shaped support and a set of storage trays. The storage trays are arranged sequentially at intervals along the vertical direction on the frame-shaped support. Crucially, the multi-layer trolley also includes a set of drip trays and a collection hopper. Each storage tray has a leakage hole. The drip trays and collection hoppers are arranged sequentially below each storage tray from top to bottom. A main pipe is provided on the frame-shaped support. The lower end of each drip tray is movably connected to one end of a connecting pipe. The drip trays are connected to the main pipe via the connecting pipe and to the collection hopper via the main pipe. Both the drip trays and collection hoppers have the freedom to be pulled back and forth on the frame-shaped support.

[0006] The leakage holes are arranged in an array along a straight line, and adjacent rows of leakage holes are alternately arranged along the array direction.

[0007] The storage tray is provided with a set of recessed guide grooves, and two adjacent leakage holes are connected to the ends of the guide grooves.

[0008] The connecting pipe is inserted into the through hole at the lower end of the liquid receiving tray.

[0009] The storage tray is provided with guide plates at both ends, and the overhanging ends of the guide plates are inclined downward and connected to the liquid receiving tray or liquid collection hopper.

[0010] The volume of the liquid collecting hopper is greater than the volume of the liquid receiving tray.

[0011] The beneficial effects of this utility model are:

[0012] This invention employs a drain hole on the storage tray and a receiving tray or hopper below each storage tray. Spilled liquid flows along the drain hole to the receiving tray or hopper below the storage tray and is collected, preventing liquid from accumulating on the storage tray or leaking from the upper storage tray onto the items on the lower storage tray, thus avoiding contamination of the items on the storage tray.

[0013] The liquid on the receiving tray enters the main pipeline along the connecting pipe and flows with the main pipeline to the liquid collection hopper located at the bottom of the frame support. This prevents the liquid from overflowing from the receiving tray to the lower storage tray when the receiving tray is carrying too much liquid, and further prevents the liquid on the upper storage tray from overflowing and leaking to the lower storage tray.

[0014] The alternating arrangement of two adjacent rows of drainage holes along the array direction helps liquid flow out of the storage tray, reduces liquid accumulation on the storage tray, and also enhances the strength of the bottom of the storage tray.

[0015] The end of the guide channel is connected to the drain hole. The guide channel collects the liquid at the bottom of the storage tray and flows out of the storage tray through the drain hole, further reducing the contact between the spilled liquid and the items on the storage tray.

[0021] In the attached diagram, 1 is a frame-type support, 2 is a storage tray, 3 is a liquid receiving tray, 4 is a main pipe, 5 is a connecting pipe, 6 is a liquid collecting hopper, 7 is a leakage hole, 8 is a flow guide channel, and 9 is a guide plate. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Specific implementation examples Figure 1 As shown, this utility model relates to a multi-layer leak-proof trolley, including a frame-type support 1, a set of storage trays 2, a set of drip trays 3, and a drip collection hopper 6. The storage trays 2 are arranged vertically at intervals on the frame-type support 1, and each storage tray 2 is provided with a leakage hole 7. The drip trays 3 and the drip collection hopper 6 are arranged from top to bottom below each storage tray 2; Figures 3-5 As shown, a main pipe 4 is provided on the frame support 1. The lower end of the liquid receiving tray 3 is movably connected to the upper end of the connecting pipe 5. The lower end of the connecting pipe 5 is connected to the main pipe 4. The liquid receiving tray 3 is connected to the liquid collecting hopper 6 through the main pipe 4. Both the liquid receiving tray 3 and the liquid collecting hopper 6 have the freedom to be pulled back and forth on the frame support 1.

[0024] The storage tray 2 at the top middle and bottom of the frame bracket 1 is provided with clearance holes for the main pipe 4 to pass through. The clearance holes are located at the corners of the storage tray 2 to reduce the interference of the main pipe 4 on the storage space of the storage tray 2.

[0025] When containers on the trolley shake or tip over, causing liquid to spill onto storage tray 2, the liquid quickly flows along the leakage hole 7 to the drip tray 3 or collection hopper 6 below the storage tray 2 for collection. This prevents liquid from accumulating on storage tray 2 or leaking from the upper storage tray 2 onto items on the lower storage tray 2, thus avoiding contamination of the items on storage tray 2. Liquid on drip tray 3 flows along connecting pipe 5 into main pipe 4 and then flows with main pipe 4 to collection hopper 6 located at the bottom of frame bracket 1. This prevents liquid from overflowing from drip tray 3 onto the lower storage tray 2 when it is overloaded, further preventing liquid from overflowing and leaking from the upper storage tray 2 onto the lower storage tray 2.

[0026] On the other hand, the liquid receiving tray 3 drains liquid into the liquid collecting hopper 6, which can reduce the setting height of the liquid receiving tray 3. When the total height of the trolley is fixed, it helps to increase the spacing between the storage trays 2 and increase the storage space.

[0027] The liquid collecting hopper 6 is spaced apart from the storage tray 2 above it to prevent liquid from flowing back into the storage tray 2 when the liquid collecting hopper 6 is full. This also makes it easier for staff to observe the amount of liquid in the liquid collecting hopper 6 and further prevents the liquid from overflowing.

[0028] The frame bracket 1 is provided with support plates for supporting the liquid receiving tray 3 and the liquid collecting hopper 6. The liquid receiving tray 3 and the liquid collecting hopper 6 can slide on the support plates and be pushed and pulled, thereby realizing the assembly and disassembly of the liquid receiving tray 3 and the liquid collecting hopper 6 on the frame bracket 1, which facilitates the cleaning of the liquid receiving tray 3 and the liquid collecting hopper 6. The frame of the frame bracket 1 limits the left and right sides of the liquid receiving tray 3 and the liquid collecting hopper 6 to prevent the liquid receiving tray 3 and the liquid collecting hopper 6 from tilting relative to the storage tray 2, so that the liquid on the upper storage tray 2 will leak onto the lower storage tray 2.

[0029] A first magnet is provided on the lower end surface of the support plate. An iron block or a second magnet matching the first magnet is provided on the bottom of the liquid receiving tray 3 and the bottom of the collection hopper 6, respectively. The iron block or the second magnet is flush with the bottom of the liquid receiving tray 3 and the bottom of the collection hopper 6, respectively. When the liquid receiving tray 3 and the collection hopper 6 are installed in place, the first magnet attracts the iron block or the second magnet, which fixes the liquid receiving tray 3 and the collection hopper 6 and prevents the liquid receiving tray 3 and the collection hopper 6 from shaking on the trolley when the trolley is bumpy.

[0030] Preferably, the drain holes 7 are arranged in a straight line array on the storage tray 2. The storage tray 2 has multiple rows of drain holes 7, and adjacent rows of drain holes 7 are alternately arranged along the array direction. The drain holes 7 can be round holes, elongated holes, polygonal holes, or irregularly shaped holes. In this embodiment, the drain holes 7 are elongated holes. The alternately arranged drain holes 7 help the liquid flow out of the storage tray 2, reduce the accumulation of liquid on the storage tray 2, and also enhance the strength of the bottom of the storage tray 2, preventing the bottom of the storage tray 2 from sinking when bearing heavy objects.

[0031] like Figure 2 As shown, the storage tray 2 is provided with a set of downwardly recessed guide grooves 8. Two adjacent leakage holes 7 are connected to the ends of the guide grooves 8. In this embodiment, the guide grooves 8 are arranged perpendicular to the long side of the leakage holes 7. The guide grooves 8 are used to collect the liquid at the bottom of the storage tray 2 where there are no leakage holes 7 and let it flow out of the storage tray 2 along the leakage holes 7, further reducing the contact between the spilled liquid and the items on the storage tray 2 and improving the cleanliness of the items on the storage tray 2.

[0032] Furthermore, a through hole is provided at the lower end of the liquid receiving tray 3. The connecting pipe 5 is inserted into the through hole at the lower end of the liquid receiving tray 3. By pulling the connecting pipe 5 out of the through hole at the lower end of the liquid receiving tray 3, the liquid receiving tray 3 can be removed from the frame bracket 1 for cleaning, saving the length of the connecting pipe 5. After the liquid receiving tray 3 is cleaned, it is reset and the connecting pipe 5 is quickly connected to the liquid receiving tray 3 by insertion.

[0033] Preferred, such as Figure 4 , Figure 5As shown, guide plates 9 are respectively provided at the left and right ends of the storage tray 2. The overhanging ends of the guide plates 9 are inclined downward and connected to the liquid receiving tray 3 or the liquid collecting hopper 6. The liquid left at the left and right ends of the storage tray 2 falls onto the liquid receiving tray 3 or the liquid collecting hopper 6 under the guidance of the guide plates 9, preventing the liquid on the storage tray 2 from leaking out of the liquid receiving tray 3 and the liquid collecting hopper 6 through the leakage holes 7 at the left and right ends. Guide plates 9 can also be provided at the front and rear ends of the storage tray 2 to further reduce interlayer leakage between the storage trays 2.

[0034] Among them, the volume of the liquid collection hopper 6 is larger than that of the liquid receiving tray 3. As the final liquid storage container, the liquid collection hopper 6 can store the liquid collected from multiple liquid receiving trays 3, which helps to reduce the frequency of pouring the liquid collection hopper 6 and also prevents the liquid from overflowing from the liquid collection hopper 6 and polluting the ground, thus ensuring the cleanliness and safety of the surrounding environment.
