Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a foldable modular wooden pallet. Background Technology

[0002] Pallets are a fundamental tool in logistics, warehousing, and transportation used for the centralized stacking, handling, and storage of goods. Through standardized design, they enable goods to be moved efficiently using equipment such as forklifts and pallet trucks. They are an indispensable part of the modern supply chain, and their main components include the base plate, railings, and foot blocks.

[0003] Existing technologies, such as the utility model patent with publication number CN203228999U, disclose a foldable storage pallet. This utility model discloses a foldable storage pallet including a square base. The base is characterized by having uprights fixedly connected to the uprights, wall mesh on two opposite sides of the base fixedly connected to the base and uprights, and door mesh on the other two opposite sides of the base movably connected to the base and detachably connected to the uprights. This utility model features standardized specifications, fixed capacity, high strength, easy inventory counting, long service life, and the ability to stack multiple pallets for three-dimensional storage and space saving. It can be used with forklifts, trolleys, and other equipment for efficient operation. Its foldable structure results in low recycling costs, making it a replacement for wooden packaging boxes.

[0004] The following defects were found in response to the above: In the prior art, pallets are usually used for stacking, handling and storing goods. When moving goods to pallets, it is often necessary to quickly place heavy or fragile goods into the pallet due to the high railings. Existing pallets do not fold or lower the railings when it is necessary to move heavy or fragile goods into the pallet, which reduces the efficiency of moving goods and increases the difficulty of moving. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing pallets, which cannot fold or lower the fence when heavy or fragile goods need to be moved onto the pallet, thus reducing the efficiency of goods handling and increasing the difficulty of handling. Therefore, a foldable modular wooden pallet is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a foldable modular wooden pallet, including a base, four folding devices are provided at the four corners of the base, each of the four folding devices includes a support column, the support column is fixedly connected to the base, the upper surface of the support column has a concave groove, both sides of the concave groove have elliptical holes, both sides of the concave groove have several positioning holes, the inner walls of two elliptical holes are slidably connected to the same round rod, the arc surface of the round rod is rotatably connected to a rectangular column, each folding device is provided with a rectangular column, the four rectangular columns are grouped in pairs, each pair of rectangular columns is adjacent to the other. A horizontal column is fixedly connected to one side of the column. Both ends of the circular rod are fixedly connected to a disc. A pin is slidably connected to one side of the disc and is slidably connected to a positioning hole. Rectangular bars are fixedly connected to both sides of the support column. A retaining plate is slidably connected to one side of the two rectangular bars and is slidably connected to the support column. A screw is threaded to one side of the retaining plate. Two first annular plates are fixedly connected to one side of each set of support columns. A rod is slidably connected to the inner wall of the two first annular plates. A baffle is fixedly connected to the end of the rod away from the annular plate. A second annular plate is fixedly connected to one side of each of the four rectangular columns.

[0007] The aforementioned components achieve the following effects: when heavy goods need to be moved and placed on a pallet, the pallet can be slid down, causing the rectangular column to rotate around the round rod to both sides. The height of the rectangular column can be adjusted by inserting and removing the pins on the disc, and the baffle can be pulled out from the first ring plate and inserted into the second ring plate on the rectangular column to raise the height of the baffle. This facilitates the movement of heavy goods onto the pallet and prevents goods from falling off the pallet.

[0008] Preferably, a rubber pad is fixedly connected to one end of the screw near the rectangular post, and the rubber pad can completely wrap the end of the screw near the rectangular post.

[0009] The effect achieved by the above components is as follows: when the screw compresses the rectangular column to prevent the rectangular column from shifting, the rubber pad can reduce the degree of wear between the rectangular column and the screw.

[0010] Preferably, a limiting plate is fixedly connected to the arc surface of the pin, a limiting rod is fixedly connected to one side of the disc, and the limiting rod is slidably connected to the limiting plate.

[0011] The effect achieved by the above components is as follows: when the pin is pulled outward, the limiting plate slides outward along the limiting rod, and the limiting rod prevents the pin from falling off the disc when it is pulled out.

[0012] Preferably, a spring is fitted on the arc surface of the pin, and the spring is fixedly connected to the disc and the limiting plate respectively.

[0013] The effect achieved by the above components is that when the pin is pulled outward, the spring is compressed by pressure, and after the height is adjusted, the pin can automatically insert into the positioning hole after being released.

[0014] Preferably, the upper surface of the chassis is provided with a cleaning device, the cleaning device including two rectangular grooves, the two rectangular grooves are opened on the upper surface of the chassis, two sliders are slidably connected to the inner walls of the two rectangular grooves, two support rings are fixedly connected to the upper surfaces of the two sliders, a rotating rod is rotatably connected to the inner walls of the two support rings, a rectangular plate is fixedly connected to the arc surface of the rotating rod, the rectangular plate is made of iron, and a cleaning brush is fixedly connected to one side of the rectangular plate.

[0015] The effect achieved by the above components is that after goods have been transported, there will inevitably be goods residue or dust on the pallet. The rectangular plate and rotating rod can be rotated to be parallel to the chassis, and the chassis can be cleaned with a cleaning brush.

[0016] Preferably, a pad is fixedly connected to one side of the crossbar, and a magnet is fixedly connected to one side of the pad.

[0017] The effect achieved by the above components is that after cleaning, the rectangular plate is rotated to the vertical base and attracted to the magnet, preventing damage during cargo handling.

[0018] Preferably, a circular ring rod is fixedly connected to one side of the support column, and the inner wall of the circular ring rod is provided with a brush.

[0019] The effect achieved by the above components is that when the cleaning brush sweeps, some dust and impurities will fall into the rectangular groove, which is then cleaned by the brush and placed into the circular rod after cleaning.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by setting an adjustment device, when goods need to be moved onto the chassis, the two rods fixedly connected to the baffle can be pulled out from the ring of the second annular plate, and then the rods of the baffle can be inserted into the ring of the first annular plate to lower the height of the baffle. Then, when the screw of the clamping plate is rotated outward, the rubber pad separates from the rectangular column, and the four clamping plates slide downward to the bottom. At this point, because the round rod and the rectangular column are rotatably connected, the rectangular column can rotate around the round rod until it is perpendicular to the clamping plate. The horizontal column between the two rectangular columns will also rotate with the support column until it is parallel to the chassis. If the rectangular and horizontal columns still obstruct or hinder the handling of goods, the pin slidably connected to the disc can be pulled outwards. During this process, the pin can be moved by pulling the limiting plate outwards. Because the spring on the pin is fixedly connected to the disc and the limiting plate, it deforms and compresses under pressure when the pin is pulled outwards. Since the limiting plate and the limiting rod are slidably connected, the distance the limiting plate can slide on the limiting rod is sufficient to pull the pin out of the positioning hole without pulling it out of the disc, thus preventing the spring from twisting and deforming. After the pin is successfully pulled out, the operator can hold the disc and slide the support column and the round rod downwards along the elliptical groove. When it reaches the appropriate position, the pin is released, and the spring's elasticity allows the pin to return along its original path and insert into the positioning hole, fixing the rectangular column. This makes handling goods much easier. The rubber pad reduces wear between the screw and the support column.

[0022] In this invention, a cleaning device is provided to prevent dust or residue buildup in various grooves of the device, such as rectangular and elliptical grooves, from hindering smooth sliding if the pallet is not cleaned for an extended period. The specific operating steps are as follows: When cleaning dust or impurities is required, the rectangular iron plate can be separated from the magnet fixedly connected to the pad plate, which is also fixedly connected to the crossbar. After the rectangular plate is separated from the magnet, it rotates within the support rings along with the rotating rod, stopping when it is parallel to the chassis. At this point, the cleaning brush fixedly connected to the rectangular plate will contact the chassis. Because there are two rectangular slots on the chassis, and a slider is slidably connected in the rectangular slots, and the slider is fixedly connected to the support ring, when the cleaning brush comes into contact with the chassis, the slider can slide in the rectangular slot, thereby driving the cleaning brush to sweep back and forth on the chassis. After cleaning is completed, the rectangular plate is rotated again to attract the rectangular plate to the magnet to prevent the goods from being moved. A brush is placed in the circular rod fixedly connected to the support column, and the brush is used to clean the dust and impurities that fall into the rectangular slot. Attached Figure Description

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a foldable combination wooden pallet, including a chassis 1, four folding devices 2 at the four corners of the chassis 1, and a cleaning device 3 on the upper surface of the chassis 1.

[0031] The specific setup and function of its folding device 2 and cleaning device 3 will be explained below.

[0032] Reference Figure 2 and Figure 3As shown in this embodiment: each of the four folding devices 2 includes a support column 201, which is fixedly connected to the base 1. A concave groove 202 is formed on the upper surface of the support column 201. Elliptical holes 203 are formed on both sides of the concave groove 202. Several positioning holes 204 are formed on both sides of the concave groove 202. The inner walls of two elliptical holes 203 are slidably connected to the same round rod 205. A rectangular column 206 is rotatably connected to the arc surface of the round rod 205. Each folding device 2 is provided with a rectangular column 206. The four rectangular columns 206 are arranged in pairs. A horizontal column 207 is fixedly connected to the side of each pair of rectangular columns 206 that is close to each other. A disc 2 is fixedly connected to both ends of the round rod 205. 08. A pin 209 is slidably connected to one side of the disc 208. The pin 209 is slidably connected to the positioning hole 204. Rectangular bars 210 are fixedly connected to both sides of the support column 201. A retaining plate 211 is slidably connected to one side of the two rectangular bars 210. The retaining plate 211 is slidably connected to the support column 201. A screw 212 is threadedly connected to one side of the retaining plate 211. Two first annular plates 217 are fixedly connected to one side of each set of support columns 201. Insert rods 218 are slidably connected to the inner walls of the two first annular plates 217. A baffle 219 is fixedly connected to the end of the insert rod 218 away from the annular plate. A second annular plate 220 is fixedly connected to one side of each of the four rectangular columns 206. When heavy goods need to be placed on a pallet, the clamping plate 211 can be slid downwards, causing the rectangular post 206 to rotate around the circular rod 205. The height of the rectangular post 206 can be adjusted by inserting and removing the pin 209 on the disc 208. The baffle 219 can also be pulled out from the first annular plate 217 and inserted into the second annular plate 220 on the rectangular post 206 to raise its height. This facilitates the transfer of heavy goods onto the pallet and prevents goods from falling off. A rubber pad 213 is fixedly connected to one end of the screw 212 near the rectangular post 206, completely encasing that end. When the screw 212 presses against the rectangular post 206 to prevent it from shifting, the rubber pad 213 reduces wear between the rectangular post 206 and the screw 212. A limiting plate 215 is fixedly connected to the arc surface of the pin 209, and a limiting rod 216 is fixedly connected to one side of the disc 208. The limiting rod 216 is slidably connected to the limiting plate 215. When the pin 209 is pulled outward, the limiting plate 215 slides outward along the limiting rod 216, preventing the pin 209 from falling off the disc 208 when pulled out. A spring 214 is fitted on the arc surface of the pin 209, and the spring 214 is fixedly connected to both the disc 208 and the limiting plate 215. When the pin 209 is pulled outward, the spring 214 is compressed under pressure. After adjusting the height, the pin 209 automatically inserts into the positioning hole 204 when released.

[0033] Reference Figure 4 , Figure 5 and Figure 6As shown in this embodiment: a cleaning device 3 is provided on the upper surface of the chassis 1. The cleaning device 3 includes two rectangular grooves 301, which are formed on the upper surface of the chassis 1. Two sliders 302 are slidably connected to the inner walls of the two rectangular grooves 301. Two support rings 303 are fixedly connected to the upper surfaces of the two sliders 302. A rotating rod 304 is rotatably connected to the inner walls of the two support rings 303. A rectangular plate 305 is fixedly connected to the arc surface of the rotating rod 304. The rectangular plate 305 is made of iron. A cleaning brush 306 is fixedly connected to one side of the rectangular plate 305. After goods have been transported, there will inevitably be goods residue or dust on the pallet. The rectangular plate 305 and the rotating rod 304 can be rotated to be parallel to the chassis 1, and the cleaning brush 306 can be used to clean the chassis 1. A pad 307 is fixedly connected to one side of the crossbar 207, and a magnet 308 is fixedly connected to one side of the pad 307. After cleaning, the rectangular plate 305 is rotated onto the vertical base 1 and attached to the magnet 308 to prevent damage during cargo handling. A circular rod 309 is fixedly connected to one side of the support column 201, and a brush 310 is provided on the inner wall of the circular ring of the rod 309. When the cleaning brush 306 cleans, some dust and impurities fall into the rectangular groove 301, are cleaned by the brush 310, and then placed back into the circular rod 309.

[0034] Working principle: In this invention, by setting an adjustment device, when goods need to be moved onto the chassis 1, the two insert rods 218 fixedly connected to the baffle 219 can be pulled out from the ring of the second annular plate 220. Then, the insert rods 218 of the baffle 219 are inserted into the ring of the first annular plate 217, lowering the height of the baffle 219. Subsequently, the screw 212 of the clamping plate 211 is rotated outward to separate the rubber pad 213 from the rectangular post 206. Then, the four clamping plates 211 are slid downward to the bottom. At this time, because the round rod 205 is rotatably connected to the rectangular post 206, the rectangular post 206 can rotate around the round rod 205 until it is perpendicular to the clamping plate 211. The horizontal post 207 between the two rectangular posts 206 will also rotate with the support post 201 until it is parallel to the chassis 1. If the rectangular column 206 and the horizontal column 207 still obstruct or make handling inconvenient when transporting goods, the pin 209, which is slidably connected to the disc 208, can be pulled outward. During the process of pulling out the pin 209, the pin 209 can be moved by pulling the limiting plate 215 outward. Since the spring 214 on the pin 209 is fixedly connected to the disc 208 and the limiting plate 215, the spring 214 will be deformed and compressed when the pin 209 is pulled outward. Since the limiting plate 215 is slidably connected to the limiting rod 216, and the distance that the limiting plate 215 can slide on the limiting rod 216 is sufficient to allow the pin 209 to be pulled out of the positioning hole 204 without pulling the pin 209 out of the disc 208, the pin 209 is prevented from being pulled out of the disc 208, thus preventing the spring 214 from twisting and deforming. After the pin 209 is successfully pulled out, the operator can hold the disc 208 by hand and slide the support column 201 and the round rod 205 downwards along the elliptical groove. When it slides to the appropriate position, the pin 209 is released, and the spring 214 uses its elasticity to make the pin 209 return along the original path and insert into the positioning hole 204, fixing the rectangular column 206. This makes it more convenient to handle goods. The rubber pad 213 reduces the wear between the screw 212 and the support column 201.

[0035] In this invention, a cleaning device is provided to prevent dust or residue buildup in various grooves of the device, such as rectangular groove 301 and elliptical groove, from hindering smooth sliding. The cleaning device 3 is designed to address this issue. Specifically, when cleaning dust or impurities is required, the rectangular iron plate 305 is detached from the magnet 308, which is fixedly connected to the pad 307, which is also fixedly connected to the crossbar 207. After detachment, the rectangular plate 305 rotates within the support rings 303, as it is fixedly connected to the rotating rod 304, which in turn rotates to the two support rings 303. The plate stops when parallel to the base 1, at which point the cleaning brush 306, fixedly connected to the rectangular plate 305, contacts the base 1. Since two rectangular grooves 301 are provided on the chassis 1, and a slider 302 is slidably connected in the rectangular grooves 301, and the slider 302 is fixedly connected to the support ring 303, when the cleaning brush 306 contacts the chassis 1, the slider 302 can slide in the rectangular grooves 301, thereby driving the cleaning brush 306 to sweep back and forth on the chassis 1. After the cleaning is completed, the rectangular plate 305 is rotated again to attract the rectangular plate 305 to the magnet 308 to prevent the handling of goods. A brush 310 is placed in the ring rod 309 fixedly connected to the support column 201, and the brush 310 is used to clean the dust and impurities that fall into the rectangular grooves 301.
