Description

Technical Field

[0001] The utility model relates to the technical field of turnover pallets, in particular to a turnover pallet with a limit and anti-drop function. Background Art

[0002] The processing and manufacturing process in the factory is inseparable from the turnover of raw materials and the transportation of various finished materials in order to complete the various processing procedures of the same item. Pallets are indispensable as a temporary turnover tool. Pallets can be used as a platform for supporting goods and products during the process of containerization, stacking, handling and transportation. They can not only be used in warehouses, but also in various types of truck transportation and material and unit transportation, so that materials and items can be circulated to facilitate the processing of items. However, when transporting items, existing turnover pallets are prone to sliding on the pallet due to uneven stacking or bumpy roads, and eventually cause the items to slip off the pallet, resulting in damage to the materials or the need for restacking, which is very inconvenient. Utility Model Content

[0003] The utility model aims to provide a turnover pallet with a limit and anti-dropping function, so as to solve the problem in the above background technology that articles slide on the pallet and thus easily fall out of the pallet.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a turnover pallet with a limit and anti-slip function, comprising a base, an outer surface of one side of the base is provided with a block-shaped protrusion, and a threaded hole is provided on the side of the base away from the block-shaped protrusion, a plate surface is provided at one end of the base away from the block-shaped protrusion, and bolts are installed through the outer surface of the plate surface, and the bolts are threadedly connected to the base, the side surface of the base is fitted with the side surface of the plate surface, and the outer surface of the plate surface is fitted with the outer surface of the bolt, an insertion port is opened inside the side of the base close to the plate surface, and a sliding mechanism is provided on the outer surface of the plate surface, and the movement of items placed on the plate surface is limited by the sliding mechanism.

[0005] Preferably, the sliding mechanism includes: a slide groove, which is opened on a side of the plate away from the base, and a card block is slidably installed inside the slide groove, and the card block is T-shaped, a pull block is rotatably installed on the end of the card block away from the plate surface, and the pull block and the card block are eccentrically designed, and a sliding block is installed through the inside of the card block, one end of the sliding block is in contact with the side surface of the pull block, and the sliding block and the card block are slidably connected, and one end of the sliding block is in contact with the side surface of the slide groove.

[0006] By adopting the above technical solution, the transported items can be placed above the board surface, and then the card block can be adjusted so that the side surface of the card block fits with the side surface of the item. Then, the pull block is pressed to make the pull block squeeze the sliding block so that the sliding block fits with the side surface of the slide groove, and the card block is lifted up. The card block is fixed through the squeezing of the sliding block and the friction between the card block and the slide groove, so that the items do not slide on the board surface during transportation, reducing the risk of items falling.

[0007] Preferably, a limiting groove is fixedly mounted on one end of the plate surface close to the base, and the side surface of the limiting groove is in contact with the side surface of the base, and the limiting groove is located inside the insertion port.

[0008] By adopting the above technical solution, the inserting teeth of the forklift can be separated through the limiting groove when the forklift is inserted into the insertion port, and the base can be easily removed and replaced after being worn.

[0009] Preferably, a rotating mechanism is provided inside the limiting groove, and the rotating mechanism is used to fix the base when the base is inserted into the insertion port and transported using a forklift, so that the base is not easy to fall off from the forklift.

[0010] By adopting the above technical solution, the forklift's inserting teeth can be inserted into the insertion port, and after the plate surface is lifted, the base cannot be directly pulled out, thereby reducing the probability of the base slipping off the forklift's inserting teeth when it is far away from the ground.

[0011] Preferably, the rotating mechanism includes: a rotating wheel, which is rotatably installed inside the limiting groove, and the rotating wheels protrude from the outer surfaces on both sides of the limiting groove, a ratchet is fixedly installed on the outer surface of the rotating wheel on the side away from the blocking block, and the ratchet and the rotating wheel are concentrically designed, a ratchet is rotatably installed inside the limiting groove, and the ratchet is engaged with the ratchet, and a first spring is arranged between the side surface of the ratchet and the limiting groove.

[0012] By adopting the above technical solution, when the forklift's spline is inserted into the base from the insertion port, the rotating wheel will rotate and cling to the side surface of the forklift's spline. After that, when the base is lifted by the forklift, the ratchet wheel and the ratchet will engage with each other, so that the rotating wheel cannot rotate in the opposite direction, thereby reducing the chance of the base accidentally slipping off the forklift's spline and preventing the transported items from falling and being damaged.

[0013] Preferably, a sliding mechanism is provided inside the limiting groove, and the sliding mechanism enables the forklift to be smoothly withdrawn from the insertion opening of the base when the base falls.

[0014] By adopting the above technical solution, when the base contacts the ground, the weight of the base and the items on the board will press the slider into the limited groove, causing the slider to push the push rod out, allowing the ratchet wheel to disengage from the ratchet teeth, allowing the rotating wheel to rotate freely, and automatically releasing the anti-slip lock after the base falls to the ground.

[0015] Preferably, the sliding mechanism includes: a pushing rod, which is fixedly mounted on the end of the ratchet away from the rotating wheel, a slider is slidably mounted inside the limiting groove, and the side of the slider close to the pushing rod is inclined, and the side surface of the pushing rod is in contact with the side surface of the slider, and a second spring is arranged between the slider and the limiting groove, one end of the slider passes through the outer surface of the base, and the base and the slider are slidably connected, and a roller is rotatably mounted on the end of the slider located outside the base.

[0016] By adopting the above technical solution, the roller can reduce the wear caused by the forklift inserting teeth pushing the base when entering the insertion port, and the direct friction between the slider and the ground is changed into rolling friction, thereby extending the service life of the slider.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the turnover pallet with position limiting and anti-dropping function:

[0018] 1. Place the items to be transported on the board, then adjust the position of the card block on the board so that the side surface of the board fits with the side surface of the transported items, then press the pull block, and the eccentric design of the pull block will press the sliding block down so that one end of the sliding block fits with the side surface of the chute, so that the chute fits tightly with the side surface of the card block. The friction generated by the card block and the chute, and the force of the sliding block pushing the chute, fix the card block, so that the transported items cannot slide on the board, reducing the risk of the transported items falling;

[0019] 2. When the forklift for transportation inserts the spline into the interior of the base through the insertion port, the spline will drive the rotating wheel to rotate, and the rotating wheel and the side surface of the insertion port will clamp the spline. When the base is lifted, the first spring pushes the ratchet to rotate, so that the ratchet is engaged with the ratchet wheel. At this time, the rotating wheel cannot rotate, and the spline cannot easily slide out of the insertion port, reducing the risk of the base sliding out when it is lifted for transportation;

[0020] 3. When the base lands on the ground, the weight of the goods, the board and the base will push the slider into the limited groove, and the second spring will be compressed. At this time, the side surface of the slider will push the push rod out, so that the ratchet wheel and the ratchet teeth are disengaged, so that the forklift teeth can be pulled out. When the base is off the ground, the second spring pushes the slider back to its original position, allowing the ratchet teeth to be pushed back by the first spring, so that the ratchet teeth are engaged with the ratchet wheel, so that the rotating wheel can be automatically unlocked after the base lands on the ground, and the rotating wheel can be automatically locked when the base is off the ground.

There is a sliding mechanism, which limits the movement of items placed on the board 2. The sliding mechanism includes: a slide groove 3, the slide groove 3 is opened on the side of the board 2 away from the base 1, and a block 5 is slidably installed inside the slide groove 3, and the block 5 is T-shaped, and a pull block 6 is rotatably installed on the end of the block 5 away from the board 2, and the pull block 6 and the block 5 are eccentrically designed, and a sliding block 7 is installed through the inside of the block 5, one end of the sliding block 7 is in contact with the side surface of the pull block 6, and the sliding block 7 is slidably connected to the block 5, and one end of the sliding block 7 is in contact with the side surface of the slide groove 3.

[0030] Place the items to be transported on the top of the board 2, and then adjust the position of the card block 5 on the board 2 so that the side surface of the card block 5 fits with the outer surface of the placed items to clamp the items, and then press the pull block 6 to push the sliding block 7 out through the eccentricity of the pull block 6, so that the sliding block 7 contacts the side surface of the slide groove 3, so that the card block 5 is lifted up, and the friction force generated by the contact and extrusion between the card block 5 and the slide groove 3 and the thrust generated by the contact between the sliding block 7 and the slide groove 3 fix the card block 5, and when the extrusion force between the sliding block 7 and the slide groove 3 becomes weak, the sliding block 7 can be pulled out and replaced, thereby reducing the damage caused by the transported items sliding and falling on the board 2 due to bumps and the like.

[0031] A limiting groove 9 is fixedly mounted on one end of the plate surface 2 close to the base 1 , and the side surface of the limiting groove 9 is in contact with the side surface of the base 1 , and the limiting groove 9 is located inside the insertion port 8 .

[0032] The base 1 can be separated from the plate 2 by limiting the separation of the groove 9 and the base 1 and unscrewing the bolt 4. The base 1 that is severely worn after long-term use can be replaced, avoiding the need to replace the entire tray after the base 1 is worn and damaged.

[0033] A rotating mechanism is provided inside the limiting groove 9, and the rotating mechanism is used to fix the base 1 when it is inserted into the insertion port 8 and transported using a forklift, so that the base 1 is not easy to fall off from the forklift.
