Description

Technical Field

[0001] This utility model belongs to the field of transfer box technology, specifically relating to a vegetable transfer box that is easy to fold. Background Technology

[0002] Transfer boxes are commonly used tools in vegetable transportation and distribution. However, traditional vegetable transfer boxes are usually structurally fixed and bulky, taking up a lot of space when not in use, making them inconvenient for storage and transportation. Existing vegetable transfer boxes have made some progress in folding technology, aiming to improve transfer efficiency, save storage space, and reduce transportation costs. These transfer boxes typically achieve folding functionality through structures such as hinges, sliding rails, or folding panels. However, while these designs meet the folding requirements to some extent, some shortcomings remain. The design of existing folding transfer boxes is too complex, making the folding and unfolding process cumbersome, sometimes even requiring tools. This not only increases the difficulty of operation but may also affect transfer efficiency. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a foldable vegetable transport box, solving the problem that the design of existing foldable transport boxes is too complicated, resulting in a cumbersome folding and unfolding process that may even require tools. This not only increases the difficulty of operation but may also affect the transport efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a foldable vegetable transport box, comprising a base plate, with inner rods fixed at the center of the upper part of both ends of the base plate, and three sets of guide rods equidistantly arranged on both sides of the inner rods. The guide rods are fixed on the upper sides of the base plate. The top of the inner rods is slidably connected to a T-shaped connecting frame. The top of the main rod of the T-shaped connecting frame is fixedly connected to the center of the lower part of both ends of the mounting frame, and the two ends of the T-shaped connecting frame are connected by support rods. Two sets of connecting rods are equidistantly arranged on both sides of the main rod of the T-shaped connecting frame, and the two ends of the connecting rods are respectively connected to the T-shaped connecting frame and the mounting frame. A sliding opening is provided on the side of the main rod of the T-shaped connecting frame facing the inner rod. The sliding cavity has an inner rod that is fitted and slidably installed within it. Both ends of the inner rod have limit slots that connect to a limiting component. The limiting component is located on one side of the main rod of the T-shaped connecting frame. The limiting component consists of a sleeve, a handle, a sliding rod, and a plug rod. Both ends of the main rod of the T-shaped connecting frame have sleeves, which are arranged vertically. A sliding rod is slidably installed inside each sleeve. One end of the sliding rod passes through the sleeve and is slidably connected to it. The other end of the sliding rod in the lower sleeve has a plug rod that passes through the T-shaped connecting frame and is slidably connected to it. The plug rod is fitted and connected to the limit slot. The top side of the mounting frame is hinged to the door.

[0005] The beneficial effects of this utility model are:

[0006] The simple yet effective structural combination of inner rods, guide rods, T-shaped connecting frames, and support rods enables convenient folding of the transport box. This not only reduces the difficulty of folding and unfolding but also improves operational efficiency. The sliding connection between the inner rod and the T-shaped connecting frame, along with the design of the limiting components, ensures the stability of the transport box in both folded and unfolded states. This helps reduce shaking during transportation and protects vegetables from damage.

[0007] The limiting component allows the insertion rod to slide by pulling the handle, thus disengaging the insertion rod from the limiting slot. When the device is folded or unfolded, releasing the handle allows the insertion rod to engage with the limiting slot, completing the unfolded or folded limiting operation. The operation is simple.

[0008] To improve the stability of this device during unfolding and folding:

[0009] As a further improvement to the above technical solution: the top end of the guide rod passes through the T-shaped connecting frame and is slidably connected to it.

[0010] The beneficial effects of this improvement are: the guide rods improve the stability of the device during unfolding and folding, and the gaps between adjacent guide rods allow vegetables to breathe better during transportation, preventing the vegetables from rotting due to accumulated moisture.

[0011] To limit the maximum range of this device's deployment:

[0012] As a further improvement to the above technical solution: a limiting plate is fixedly provided at the top of each guide rod.

[0013] The beneficial effect of this improvement is that the limiting plate limits the maximum range of the device's unfolding.

[0014] To provide additional support and stability:

[0015] As a further improvement to the above technical solution: one end of the second baffle is rotatably connected to the upper sides of both sides of the base plate, and the other end of the second baffle is rotatably connected to one end of the first baffle, and the other end of the first baffle is rotatably connected to the lower sides of both sides of the mounting bracket, and the maximum angle between the first baffle and the second baffle is 170 degrees.

[0016] The benefits of this improvement are that it makes the device more compact when folded, while providing additional support and stability during use.

[0017] To limit the movement of this device after folding and unfolding:

[0018] As a further improvement to the above technical solution: a spring is sleeved on the outer side of the sliding rod, and the two ends of the spring are connected to the inner wall of one end of the sliding rod and the sleeve, and the other end of the sliding rod is connected to a handle.

[0019] The beneficial effects of this improvement are as follows: The user can hold the handle with both hands and pull it outward. At this time, the sliding rod slides inside the sleeve, the spring is compressed and contracts, and the insert rod slides into the sleeve, thus disengaging from one set of limiting slots. If the device is unfolded to a suitable height, the handle can be released. At this time, the elastic potential energy of the spring will cause the insert rod to slide into the sliding cavity and engage with another set of limiting slots, thereby completing the unfolding limitation of the device. Similarly, when folding the device, the handle can be pulled outward and then pulled downward. At this time, the T-shaped connecting frame drives the mounting frame to move downward. When the device is folded to a suitable height, the handle can be released and the insert rod engages with the limiting slot in the appropriate position, thereby completing the folding limitation of the device.

[0020] To quickly complete the deployment of this device:

[0021] As a further improvement to the above technical solution: a second spring is fixedly provided at the top of the sliding cavity, and one end of the second spring is connected to the top of the inner rod.

[0022] The beneficial effects of this improvement are as follows: when the device is in a folded state, the second spring is compressed into an elastic contraction state, and when it needs to be unfolded, the elastic potential energy of the second spring can make the T-shaped connecting frame slide upward quickly, thus quickly completing the unfolding of the device.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] like Figure 1-3 As shown, the easily foldable vegetable transport box includes a base plate 1. Inner rods 3 are fixed at the center of the upper part of both ends of the base plate 1. Three sets of guide rods 2 are equidistantly spaced on both sides of the inner rods 3. The guide rods 2 are fixed on the upper sides of the base plate 1. A T-shaped connecting frame 4 is slidably connected to the top of the inner rod 3. The top of the main rod of the T-shaped connecting frame 4 is fixedly connected to the center of the lower part of both ends of the mounting frame 6. The two ends of the T-shaped connecting frame 4, which are arranged opposite each other, are connected by support rods 7. Two sets of connecting rods 601 are equidistantly arranged on both sides of the main rod of the T-shaped connecting frame 4. The two ends of the connecting rods 601 are respectively connected to the T-shaped connecting frame 4 and the mounting frame 6. A sliding cavity is opened on the side of the main rod of the T-shaped connecting frame 4 facing the inner rod 3, and the inner rod 3 is fitted and slidably installed in the sliding cavity. Limiting slots 3 are opened through both ends of the inner rod 3. 01, the limiting slot 301 is connected to the limiting component 10, and the limiting component 10 is set on one side of the main rod of the T-shaped connecting frame 4. The limiting component 10 is composed of a sleeve 1001, a handle 1002, a sliding rod 1003, and an insert rod 1004. Sleeves 1001 are provided at both ends of one side of the main rod of the T-shaped connecting frame 4. The two sets of sleeves 1001 are arranged vertically, and a sliding rod 1003 is slidably installed in each sleeve 1001. One end of the sliding rod 1003 passes through the sleeve 1001 and is slidably connected to it. The other end of the sliding rod 1003 in the lower sleeve 1001 is provided with an insert rod 1004, and the insert rod 1004 passes through the T-shaped connecting frame 4 and is slidably connected to it. The insert rod 1004 is fitted into the limiting slot 301. The top side of the mounting frame 6 is hinged to the box door 5.

[0030] The top end of the guide rod 2 passes through the T-shaped connecting frame 4 and is slidably connected to it; the guide rod 2 improves the stability of the device during unfolding and folding, and the gap between adjacent guide rods 2 allows vegetables to breathe better during transportation, preventing the vegetables from rotting due to accumulated moisture.

[0031] Each guide rod 2 has a limiting plate 201 fixed at its top end; the limiting plate 201 limits the maximum range of the device's unfolding.

[0032] Both sides of the base plate 1 are rotatably connected to one end of the second baffle 9, and the other end of the second baffle 9 is rotatably connected to one end of the first baffle 8. The other end of the first baffle 8 is rotatably connected to the lower sides of the mounting bracket 6, and the maximum angle between the first baffle 8 and the second baffle 9 is 170 degrees; this makes the device more compact when folded, and at the same time provides additional support and stability when in use.

[0033] A spring is sleeved on the outer side of the sliding rod 1003, and the two ends of the spring are connected to the inner wall of one end of the sliding rod 1003 and the sleeve 1001. The other end of the sliding rod 1003 is connected to the handle 1002. When the user holds the handle 1002 with both hands and pulls it outward, the sliding rod 1003 slides inside the sleeve 1001. The spring is compressed and contracts, and at the same time, the insertion rod 1004 slides into the sleeve 1001, thus disengaging from one of the limiting slots 301. If the device is unfolded to a suitable height, it can... When handle 1002 is released, the elastic potential energy of spring 1 allows the insert rod 1004 to slide into the sliding cavity and engage with another set of limiting slots 301, thus completing the unfolding limitation of the device. Similarly, when folding the device, handle 1002 can be pulled outward and then pulled downward. At this time, the T-shaped connecting frame 4 drives the mounting frame 6 to move downward. When the device is folded to a suitable height, handle 1002 is released and the insert rod 1004 engages with the limiting slot 301 in the appropriate position, thus completing the folding limitation of the device.

[0034] A second spring is fixed at the top of the sliding cavity, and one end of the second spring is connected to the top of the inner rod 3. When the device is in a folded state, the second spring is compressed into an elastic contraction state. When it needs to be unfolded, the elastic potential energy of the second spring can make the T-shaped connecting frame 4 slide upward quickly, so as to quickly complete the unfolding of the device.

[0035] The working principle and usage of this utility model are as follows: The user can hold the handle 1002 with both hands and pull it outward. At this time, the sliding rod 1003 slides inside the sleeve 1001, and the spring is compressed and contracts. At the same time, the insertion rod 1004 slides into the sleeve 1001, thus disengaging from one set of limiting slots 301. If the device is unfolded to a suitable height, the handle 1002 can be released. At this time, the elastic potential energy of the spring will cause the insertion rod 1004 to slide into the sliding cavity and engage with another set of limiting slots 301, thereby completing the unfolding limitation of the device. Similarly, when folding the device, it can be pulled outward. Move handle 1002, then pull handle 1002 downwards. At this time, T-shaped connecting frame 4 drives mounting frame 6 to move downwards. When the device is folded to a suitable height, release handle 1002 and insert rod 1004 into the appropriate position limit slot 301, thereby completing the limiting of the device after folding. Spring 2 is compressed into an elastic contraction state when the device is folded. When it needs to be unfolded, the elastic potential energy of spring 2 can make T-shaped connecting frame 4 slide upwards quickly, thus quickly completing the unfolding of the device. The gap between adjacent guide rods 2 can allow vegetables to breathe better during transportation, preventing the accumulation of moisture from causing the vegetables to rot.
