Description

Technical Field

[0001] This utility model relates to the field of plastic pallet technology, specifically to a plastic pallet that can be stacked stably. Background Technology

[0002] Plastic pallets are flat logistics tools made of plastic and used to carry and transport goods. They are one of the mainstream alternatives to wooden pallets in modern logistics. Compared with traditional wooden pallets, they are less susceptible to moisture, mold, and insects, and are more impact-resistant and have a longer service life. Their smooth surface is easy to clean and meets the hygiene standards of the food and pharmaceutical industries. They are lighter than metal pallets, making them easier to handle, and they can also be recycled.

[0003] For example, Chinese utility model patent with announcement number "CN219134847U" discloses a plastic pallet; by rotating the handwheel, its lead screw rotates and engages with the threaded plate, thereby achieving threaded lifting and lowering control of the threaded plate. Then, supported by the support rods on both sides of the bottom end of the threaded plate, the first anti-slip rubber pad is lowered and extended until it contacts the ground to achieve the anti-slip effect. At the same time, the first anti-slip rubber pad can continue to descend after wear, so that it can be replaced after use.

[0004] The aforementioned prior art has the following shortcomings in actual implementation: Although the anti-slip rubber pad makes the tray anti-slip, there is no protective structure on both sides of the tray, making the items placed on the tray easily affected by external factors. Furthermore, the tray is not placed with anti-slip measures, so the items may slide and fall due to the tilt of the placement position. Utility Model Content

[0005] One of the technical problems that this application aims to solve is that although existing plastic pallets can achieve anti-slip by using anti-slip rubber pads, they have the defects of having no protective structure on both sides and lacking effective anti-slip measures at the placement position, which makes the items on the pallet susceptible to external influences and may slide and fall off due to the tilted placement position.

[0006] To address the aforementioned technical problems, embodiments of this application provide a stable stackable plastic pallet, comprising: The first tray is rectangular in design. An adjustable placement structure includes a first sliding groove, which is formed on both sides inside the first tray; a first slider, which is disposed inside the first sliding groove; a scissor hinge, one side of which is hinged to one side of the first slider; a second slider, which is hinged to the other side of the scissor hinge; a second tray, which is disposed outside the second slider; a second sliding groove, which is formed inside the second tray; a placement groove, which is formed on the upper surfaces of the first tray and the second tray; and a rubber pad, which is fixedly connected to the bottom of the placement groove.

[0007] In some embodiments, the first slider is slidably connected to the first groove, and the second slider is disposed inside the second groove and slidably connected to the second groove. Each first groove and the second groove are provided with two first sliders and two second sliders inside.

[0008] In some embodiments, the first tray and the second tray are provided with an auxiliary protective structure, the auxiliary protective structure including: a slot, the slot being formed on both sides of the upper surface of the first tray and the second tray; a protective plate, the protective plate being slidably connected inside the slot, the protective plate extending from the slot to the upper side of the first tray and the second tray.

[0009] In some embodiments, the surfaces of the first tray, the second tray, and the rubber pad are provided with through holes, and a plurality of through holes are provided.

[0010] In some embodiments, the first tray has a positioning structure inside, the positioning structure including: a connecting plate, the connecting plate being fixedly connected to one side of the first slider and disposed inside the first slide groove and slidably connected to the first slide groove; a hidden groove, the hidden groove being formed on the side surface of the connecting plate; a locking plate, the locking plate being disposed inside the hidden groove and slidably connected to the hidden groove; a guide rod, the guide rod being fixedly connected to one side of the connecting plate; a spring, the spring being sleeved on the outside of the guide rod and disposed between the locking plate and the inner side of the hidden groove; a pull block, the pull block being fixedly connected to one end of the guide rod and disposed on the outside of the locking plate, and a fixing groove being formed on the inner surface of the first slide groove, the locking plate being adapted to the fixing groove.

[0011] In some embodiments, the interior of the first tray and the second tray is provided with an auxiliary moving structure, the auxiliary moving structure including a setting groove formed on the left and right side surfaces of the first tray and the second tray, and a handle fixedly connected to the inside of the setting groove.

[0012] In some embodiments, a support structure is provided on the lower side of the first tray, the support structure including support legs fixed at the four corners of the lower side of the first tray and rubber bases fixed to the support legs.

[0013] This utility model has at least the following beneficial effects: This structure, utilizing a combination of a chute, a slider, and a scissor hinge, allows for flexible adjustment of the distance between the first and second pallets, accommodating goods of different sizes. The scissor hinges are positioned on both sides of the first pallet. Items are primarily placed on the first pallet, allowing fragile goods to be placed on it for added stability and protection. The second pallet provides additional protection to the top of the first pallet, and can hold more robust items.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a stable stackable plastic pallet, comprising: First tray 1, first tray 1 is rectangular in design; The adjustable placement structure includes a first slide groove 101, which is formed on both sides inside the first tray 1; a first slider 102, which is disposed inside the first slide groove 101; a scissor hinge 103, one side of which is hinged to one side of the first slider 102; a second slider 104, which is hinged to the other side of the scissor hinge 103; a second tray 105, which is disposed outside the second slider 104; and a second slide groove 101. 6. The second slide groove 106 is formed inside the second tray 105; the placement groove 107 is formed on the upper surface of the first tray 1 and the second tray 105; the rubber pad 108 is fixedly connected to the bottom of the placement groove 107; the first slider 102 is slidably connected to the first slide groove 101, and the second slider 104 is set inside the second slide groove 106 and slidably connected to the second slide groove 106. Each first slide groove 101 and the second slide groove 106 are provided with two first sliders 102 and two second sliders 104.

[0018] Through the above technical solution, the pallet bearing area can be flexibly adjusted by combining "slide groove + slider + scissor hinge". The first slide groove 101 and the second slide groove 106 are respectively opened inside the first pallet 1 and the second pallet 105. The first slider 102 and the second slider 104 slide in the corresponding slide grooves, and the two ends of the scissor hinge 103 are respectively hinged to the two types of sliders. When the second pallet 105 is pulled, the scissor hinge 103 unfolds or retracts, causing the slider to slide along the slide groove, thereby changing the distance between the first pallet 1 and the second pallet 105 to adapt to the placement needs of goods of different sizes. At the same time, two sliders are set in each slide groove to ensure that the scissor hinge 103 is subjected to balanced force and avoids the pallet tilting during the adjustment process. The placement groove 107 provides positioning space for the goods, and the rubber pad 108 at the bottom can increase the friction between the goods and the pallet to prevent the goods from sliding during placement or handling.

[0019] Please see Figures 1-5 The first tray 1 and the second tray 105 are provided with auxiliary protective structures, which include: a slot 201, which is opened on both sides of the upper surface of the first tray 1 and the second tray 105; and a protective plate 202, which is slidably connected inside the slot 201 and extends from the slot 201 to the upper side of the first tray 1 and the second tray 105.

[0020] The above technical solution achieves the protective function through the detachable design of "slot + protective plate"; the slot 201 is opened on both sides of the upper surface of the first pallet 1 and the second pallet 105, and the protective plate 202 is slidably connected to the slot 201 and extends to the upper side of the pallet; when protection is needed, the protective plate 202 is slid into the slot 201, and its height can block external collisions or cargo shifting, preventing the cargo from falling due to external factors; when protection is not needed, the protective plate 202 can be pulled out from the slot 201 without occupying extra space, which is convenient for pallet stacking or storage.

[0021] Please see Figures 1-5 The surfaces of the first tray 1, the second tray 105 and the rubber pad 108 are provided with through holes 301, and there are several holes 301.

[0022] Through the above technical solution, the drain hole 301 is opened through the surface of the first pallet 1, the second pallet 105 and the rubber pad 108, and several holes are provided. This structure mainly solves the problem of water and debris accumulation on the pallet: if the goods are wet or the environment is humid, the water can be quickly discharged through the drain hole 301 to avoid the goods from getting damp and deteriorating due to residual water; at the same time, the debris and impurities generated during the handling of goods can also fall through the drain hole 301 to keep the pallet surface clean.

[0023] Please see Figures 1-5 The first tray 1 has a positioning structure inside, which includes: a connecting plate 401, which is fixedly connected to one side of the first slider 102 and is disposed inside the first slide groove 101 and slidably connected to the first slide groove 101; a hidden groove 402, which is opened on the side surface of the connecting plate 401; a locking plate 403, which is disposed inside the hidden groove 402 and slidably connected to the hidden groove 402; a guide rod 404, which is fixedly connected to one side of the connecting plate 401; a spring 405, which is sleeved on the outside of the guide rod 404 and is disposed between the locking plate 403 and the inner side of the hidden groove 402; and a pull block 406, which is fixedly connected to one end of the guide rod 404 and is disposed on the outside of the locking plate 403. A fixing groove 407 is opened on the inner surface of the first slide groove 101, and the locking plate 403 is adapted to the fixing groove 407.

[0024] Through the above technical solution, the slider position is fixed by "elastic engagement" to avoid tray displacement after adjustment; the connecting plate 401 is fixed to the first slider 102 and slides with the slider in the first slide groove 101; the hidden groove 402 is opened on the side of the connecting plate 401; the locking plate 403 slides in the hidden groove 402; one end of the guide rod 404 is fixed to the locking plate 403, and the other end is connected to the pull block 406; the spring 405 is sleeved on the outside of the guide rod 404 and located between the locking plate 403 and the inner side of the hidden groove 402; when When the slider slides, the locking plate 403 is squeezed into the hidden groove 402 by the inner wall of the slide groove, compressing the spring 405. When the slider slides to the target position, the locking plate 403 is aligned with the fixing groove 407 on the inner side of the first slide groove 101, and the spring 405 resets and pushes the locking plate 403 into the fixing groove 407 to achieve slider positioning. When adjustment is required again, pull the pull block 406, and the guide rod 404 drives the locking plate 403 to disengage from the fixing groove 407 and retract into the hidden groove 402 to release the positioning. The operation is convenient and the positioning is stable.

[0025] Please see Figures 1-5 The first tray 1 and the second tray 105 are provided with auxiliary moving structures inside. The auxiliary moving structures include setting grooves 501 opened on the left and right sides of the first tray 1 and the second tray 105, and handles 502 are fixedly connected to the inside of the setting grooves 501.

[0026] The above technical solution combines practicality and aesthetics through the concealed design of "setting groove 501 + handle 502"; the setting groove 501 is opened on the left and right sides of the first pallet 1 and the second pallet 105, and the handle 502 is fixed inside the setting groove 501; when moving the pallet, the operator can hold the handle 502 to apply force, avoiding direct contact with the edge of the pallet and thus avoiding hand wear.

[0027] Please see Figures 1-5 The first tray 1 has a support structure on its lower side, which includes support legs 601 fixed at the four corners of the lower side of the first tray 1 and rubber bases 602 fixed to the support legs 601.

[0028] The above technical solution improves the stability of the pallet by using "support legs 601 + rubber base 602". The support legs 601 are fixed to the four corners of the lower side of the first pallet 1, providing support height for the pallet and preventing the bottom of the pallet from directly contacting the ground, thus reducing the corrosion of the pallet by ground moisture. The rubber base 602 is fixed to the bottom of the support legs 601. Its material has high friction, which can increase the contact friction between the pallet and the ground, preventing the pallet from sliding due to ground tilt or external impact. At the same time, the rubber material can buffer the impact force during handling, protecting the ground and the pallet itself.

[0029] Working principle and usage procedure: In use, the scissor hinge 103 can be unfolded by pulling the second tray 105. At this time, the first slider 102 slides in the first slide groove 101, and the second slider 104 slides in the second slide groove 106, thereby adjusting the distance between the first tray 1 and the second tray 105. During the adjustment process, the positioning structure plays a role. When the first slider 102 slides, it drives the connecting plate 401 to move. The locking plate 403 is locked into the fixing groove 407 under the elastic force of the spring 405, realizing the positioning of the first slider 102, thereby fixing the position of the second tray 105. When not in use, the pull block 406 is pulled, and the guide rod... 404 drives the card plate 403 to compress the spring 405 and retract into the hidden groove 402, thus releasing the positioning; when the item is placed in the placement groove 107, the rubber pad 108 increases the friction and prevents the item from sliding; the protective plate 202 in the auxiliary protective structure can be pulled out from the card slot 201 to shield and protect the placed item from external factors; the drain hole 301 can drain the water or impurities in the placement groove 107; when the device needs to be moved, it can be moved by the handle 502 in the groove 501; the support leg 601 in the support structure supports the first tray 1, and the rubber base 602 increases the friction with the ground and improves the overall stability.
