Description

TECHNICAL FIELD

[0001] The present application relates to the field of plastic pallets, in particular to a plastic pallet with anti-falling buckle structure. BACKGROUND

[0002] The pallet is a medium for converting static goods into dynamic goods, a cargo carrying platform, and a movable platform, or a movable ground. Even if the goods lose flexibility when placed on the ground, they immediately gain mobility and become flexible mobile goods as soon as they are loaded onto the pallet. Because the goods loaded on the pallet are always in a state of readiness to enter motion at any time, this dynamic loading and unloading method using a pallet as a basic tool is called pallet operation.

[0003] As disclosed in the patent with the patent publication number CN208233623U, a buckle type plastic pallet, still has the following deficiencies in actual use:

[0004] The goods that need to be transported have different volumes. The device fixes the first clamping strip, the second clamping strip, the third clamping strip, the fourth clamping strip, the fifth clamping strip and the sixth clamping strip on the top of the pallet board through the first rope and the second rope, and firmly controls the goods within a limited range. It cannot limit goods of different volumes, and has limitations. CONTENT OF THE UTILITY MODEL

[0006] The plastic pallet with anti-falling buckle structure provided by the present application adopts the following technical scheme:

[0007] A plastic pallet with anti-falling buckle structure, comprising a pallet two movably connected with a pallet one, the top of the pallet one and the top of the pallet two are movably connected with a side plate perpendicular thereto through a hinge one on the side away from each other, the top of the pallet one and the top of the pallet two are provided with a cavity, the two cavities are movably connected with a clamping strip at both ends of the top through a hinge two, the hinge two is movably installed in the cavity, the two cavities are provided with a driving assembly, the driving assembly comprises a lead screw screwedly connected between the two hinge twos, the lead screw is provided with a thread one and a thread two with opposite rotation directions at both ends of the surface respectively, when the lead screw rotates, the pair of clamping strips screwedly connected with the lead screw have the trend of approaching or moving away from each other;

[0008] One end of each of the two lead screws is fixedly connected with a T-shaped rotating handle, the other end of which is movably penetrated through the side wall of the tray 1 and the tray 2 and extends to the outside, the inside of the tray 1 and the tray 2 is provided with a limiting assembly corresponding to the position of the T-shaped rotating handle, the limiting assembly comprises a friction block movably arranged in the inside of the tray 1 and the tray 2, and the side of the surface of the friction block close to the T-shaped rotating handle abuts against the surface of the T-shaped rotating handle.

[0009] By adopting the above technical scheme, the card strip is movably connected in the cavity through the hinge two, which allows the card strip to be unfolded to clamp the goods when needed, and to be folded and stored in the cavity when not needed, thereby saving space and facilitating transportation. When the lead screw rotates, the pair of card strips connected with the lead screw have a tendency to move close to each other or move away from each other, so that the distance between the card strips can be flexibly adjusted according to the volume of the goods. The side plates are movably connected to the top of the tray 1 and the tray 2 through the hinge one, and are arranged perpendicularly to the tray. The side plates on both sides can clamp the goods on both sides, and the tray 1 and the tray 2 can move relative to each other to adapt to goods of different volumes, thereby firmly controlling the goods within a limited range, achieving the purpose of preventing the goods from falling and toppling over;

[0010] During transportation, the side plates and the card strips provide support for the goods, preventing the goods from falling and toppling over during transportation, ensuring work efficiency and safety, and solving the problem of easy falling and toppling over of goods in the prior art.

[0011] The friction block is movably arranged in the inside of the tray 1 and the tray 2, and abuts against the surface of the T-shaped rotating handle, effectively preventing the T-shaped rotating handle from rotating by itself when not subjected to external force, thereby ensuring the stability of the buckle structure.

[0012] Preferably, a sliding groove one is formed in the top of each of the two cavities, the two groups of hinge two are located in the corresponding sliding groove one and realize horizontal sliding, and the two ends of the lead screw are threaded through the side wall of the two ends of the hinge two and are respectively rotatably connected in the inside of the sliding groove one.

[0013] By adopting the above technical scheme, the shape of the sliding groove one is matched with the hinge two, and the hinge two can smoothly slide in the sliding groove one without being hindered or generating unnecessary friction.

[0014] Preferably, a through hole is formed in one side of the tray 1 and the tray 2, the shape of the through hole is matched with the T-shaped rotating handle, a sliding groove two is formed in the tray 1 and the tray 2 and communicates with the through hole, the sliding groove two is matched with the shape of the friction block, and the friction block is located in the sliding groove two and realizes horizontal sliding.

[0016] Preferably, the friction block is fixed on one side of the T-shaped rotating handle, and the other end of the friction block is fixed on one side of the spring in the inner cavity of the sliding groove.

[0017] By adopting the above technical scheme, through the close fit of the friction block and the T-shaped rotating handle and the resetting action of the spring, stable positioning of the T-shaped rotating handle is realized. This helps to prevent accidental movement or loosening of the tray during adjustment, improving the overall stability of the tray structure.

[0018] Preferably, a right-angled triangular groove is formed in the center of one end of the friction block, and a threaded rod extending into the right-angled triangular groove is threadedly connected to the corresponding right-angled triangular groove position on one side of the tray one and the tray two.

[0019] By adopting the above technical scheme, the right-angled triangular groove formed in the center of one end of the friction block cooperates with the threaded rod threadedly connected on one side of the tray one and the tray two. The user can adjust the position of the threaded rod in the right-angled triangular groove by rotating the threaded rod, thereby changing the contact pressure and positioning effect between the friction block and the T-shaped rotating handle.

[0020] Preferably, a limiting disc is fixedly sleeved on the surface of the threaded rod, a threaded hole two is formed on one side of the tray one and the tray two, and the shape of the threaded hole two is adapted to the shape of the threaded rod, a sliding groove three is formed on the surface of the inner cavity of the threaded hole two, and the shape of the sliding groove three is adapted to the shape of the limiting disc.

[0021] By adopting the above technical scheme, the limiting disc on the surface of the threaded rod realizes horizontal sliding in the sliding groove three, which ensures that the threaded rod remains stable during rotation and prevents it from falling out of the threaded hole two.

[0022] Preferably, a plurality of slide rods are fixedly connected to one side of the tray one at equal intervals, a plurality of sliding grooves four are formed on one side of the tray two, and the shape of the sliding grooves four is adapted to the shape of the slide rods.

[0025] By adopting the above technical scheme, the design of the limiting block helps to prevent the sliding rod from accidentally falling out of the sliding groove during the sliding process. Even under external force, the sliding rod will remain in the sliding groove due to the presence of the limiting block, ensuring that the connection between tray one and tray two will not be interrupted.

[0042] The following will be described in detail in combination with the accompanying drawings Figures 1-9 The application is further described in detail.

[0043] The embodiment of the application discloses a plastic tray with anti-falling buckle structure.

[0044] Reference Figures 1-4 The plastic tray with anti-falling buckle structure comprises a plurality of sliding rods 12 fixed on one side of a tray one 1, the plurality of sliding rods 12 are arranged at equal intervals, a plurality of sliding grooves four 13 are formed on the side of a tray two 2 corresponding to the positions of the plurality of sliding rods 12, the plurality of sliding rods 12 are located in the corresponding sliding grooves four 13, and the periphery of the sliding rod 12 surface abuts against the periphery of the sliding groove four 13 inner wall, the length of the sliding groove four 13 is equal to the length of the sliding rod 12, and the end of the sliding groove four 13 close to the tray one 1 is an opening, so that the sliding rod 12 can realize horizontal sliding when located in the sliding groove four 13, a plurality of limiting blocks 14 are fixedly sleeved on the same position of the surface of the plurality of sliding rods 12, a plurality of sliding grooves five 15 are formed in the tray two 2 corresponding to the positions of the plurality of sliding grooves four 13, and the sliding groove five 15 is communicated with the sliding groove four 13, the limiting block 14 is located in the sliding groove five 15 and the periphery of the limiting block 14 surface abuts against the periphery of the sliding groove five 15 inner wall, and the length of the sliding groove five 15 is greater than the height of the limiting block 14, so that the limiting block 14 can horizontally slide in the sliding groove five 15.

[0045] The hinge one 3 is provided with two groups, each group is provided with two, the hinge head of one group of the hinge one 3 is fixed on the top of the tray one 1 away from the tray two 2, the hinge head of the other group of the hinge one 3 is fixed on the top of the tray two 2 away from the tray one 1, the base of the same group of the hinge one 3 is fixed with one side of the same side plate 4, and the side plate 4 is rotated by 90 degrees through the hinge one 3, so that the side plate 4 is perpendicular to the tray one 1 and the tray two 2.

[0046] When the relative position between tray one 1 and tray two 2 needs to be adjusted, the user can push tray one 1 or tray two 2 to make the slide rod 12 slide in the slide groove four 13. The sliding of the limiting block 14 in the slide groove five 15 ensures the stable connection between tray one 1 and tray two 2, preventing the slide rod 12 from falling off. When the goods need to be enclosed, the user can turn the side plate 4 through the hinge one 3 by 90 degrees, making it perpendicular to tray one 1 and tray two 2. In this way, the side plate 4, tray one 1 and tray two 2 together form a closed enclosure structure, which can effectively prevent the goods from scattering or toppling over during transportation.

[0047] Referring to Figures 5-7 , the cavity 5 is opened at the top of tray one 1 and tray two 2, the slide groove one 9 is opened at the top of the cavity 5, the hinge two 7 is respectively located at the top of the slide groove one 9, and the bottom and both sides of the hinge two 7 respectively abut the bottom and both sides of the slide groove one 9, and the length of the slide groove one 9 is greater than the length of the hinge head of the hinge two 7, so that the hinge two 7 can slide horizontally in the slide groove one 9, the bases of the two hinge two 7s on the same side are fixedly connected to the inner side of the clamping strip 6, and the drive assembly 8 is arranged in the slide groove one 9. The drive assembly 8 includes a lead screw 81 rotatably connected at the center of both ends of the inner cavity of the slide groove one 9, and the surface of the lead screw 81 is provided with a thread one 82 and a thread two 83 at both ends. The thread one 82 and the thread two 83 are opposite in rotation direction, and the hinge head side of both ends of the hinge two 7 is respectively provided with a thread hole one 10 matched in shape with the thread one 82 and the thread two 83. The hinge head of the hinge two 7 is threadedly connected to both ends of the lead screw 81 through the thread hole one 10. When the lead screw 81 rotates clockwise, the two hinge two 7s are close to each other, and when the lead screw 81 rotates counterclockwise, the two hinge two 7s are away from each other. The side of the tray one 1 and the side of the tray two 2 corresponding to the position of the lead screw 81 are respectively provided with a through hole 85, and the horizontal rod 86 of the T-shaped rotating handle 84 passes through the through hole 85 and is fixedly connected to one end of the lead screw 81. The surface of the horizontal rod 86 abuts the inner wall of the through hole 85.

[0048] The shape of the cavity 5 is matched with the shape of the clamping strip 6. When the clamping strip 6 is folded and stored through the hinge two 7, it is just located in the cavity 5, and at this time, the top of the clamping strip 6 is flush with the top of the tray one 1 and the tray two 2. When the clamping strip 6 is turned by 90 degrees through the hinge two 7, the clamping strip 6 is perpendicular to the tray one 1 and the tray two 2.

[0049] In order to prevent the clamping strip 6 from being damaged or deformed due to excessive extrusion when clamping the goods, a buffer layer (such as a rubber pad, a foam pad, etc.) can be arranged on the contact surface of the clamping strip 6. This not only improves the durability of the clamping strip 6, but also protects the goods from damage.

[0050] In its initial state, the card strip 6 is cleverly folded and stored in the cavity 5 via hinge 2 7. At this time, the top of the card strip 6 is perfectly flush with the tops of pallet 1 and pallet 2, forming a flat and continuous surface. This design not only saves a lot of space but also ensures the stability and compactness of the pallet during transportation or storage.

[0051] In use, the locking strip 6 is rotated 90 degrees by hinge 2 7 so that it is perpendicular to pallet 1 and pallet 2 2. Then, the screw 81 is driven by rotating the T-shaped rotating handle 84. Rotating the T-shaped rotating handle 84 clockwise causes the screw 81 to rotate clockwise, so that the hinge 2 7 threaded at both ends of the screw 81 moves closer to each other, thereby causing the locking strip 6 fixed on the hinge 2 7 to move closer to each other. This allows the locking strips 6 on both sides to clamp the goods. The distance between the locking strips 6 on both sides can be flexibly adjusted according to the volume of the goods. In this way, the side plates 4 on both sides, pallet 1, pallet 2 2 and the locking strips 6 on both sides together form a closed enclosure structure, which can effectively prevent the goods from scattering or tipping over during transportation.

[0052] Reference Figure 8 , Figure 9 The limiting component 11 is disposed inside the first tray 1 and the second tray 2. The limiting component 11 includes a friction block 111 that is movably disposed inside the first tray 1 and the second tray 2. It is advisable to use more wear-resistant and stable materials to manufacture the friction block 111 and optimize its structural design to reduce wear and failure rate. Friction block 111 abuts against the surface of the horizontal plate on the side near the crossbar 86 to generate friction. The inner wall of the through hole 85 is provided with a sliding groove 112 that matches the shape of friction block 111. The length of sliding groove 112 is greater than the length of friction block 111, so that friction block 111 can slide laterally in sliding groove 112. A spring 113 is fixedly connected to the center of the side of friction block 111 away from the crossbar 86. The end of spring 113 away from friction block 111 is fixedly connected to the center of the inner cavity of sliding groove 112 away from the crossbar 86. A right-angled triangular groove 114 is opened at the center of the end of friction block 111 away from the lead screw 81. A threaded hole 117 is opened on the side of tray 1 and tray 2 corresponding to the right-angled triangular groove 114. Threaded hole 117 is connected to sliding groove 112. Threaded rod 115 is threadedly connected in threaded hole 117. The inner end of threaded rod 115 extends into right-angled triangular groove 114.

[0053] The limiting plate 116 is fixedly sleeved on the surface of the threaded rod 115. The sliding groove 118 is opened on the inner wall of the threaded hole 117. The limiting plate 116 is located in the sliding groove 118 and its surface abuts against the inner wall of the sliding groove 118. The lateral depth of the sliding groove 118 is greater than the height of the limiting plate 116, so that the limiting plate 116 can slide laterally in the sliding groove 118.

[0054] When no external force is applied, the friction block 111 remains in its initial position under the restoring force of the spring 113. At this time, there is friction between the friction block 111 and the crossbar 86, generating sufficient friction to restrict the movement or rotation of the crossbar 86. When it is necessary to release the limit, the threaded rod 115 is rotated clockwise so that its inner end abuts against the inclined surface of the right-angled triangular groove 114. The threaded rod 115 then pushes the friction block 111 to slide within the slide groove 112. As the friction block 111 slides, it no longer abuts against the surface of the crossbar 86, and the friction between them disappears, allowing the crossbar 86 to rotate freely again. When it is necessary to restore the limit, the threaded rod 115 is rotated counterclockwise again so that its inner end exits from the right-angled triangular groove 114. Under the restoring force of the spring 113, the friction block 111 will return to its initial position, at which point the crossbar 86 cannot rotate.

[0055] To ensure the stability and durability of the pallet when carrying heavy loads, consider adding reinforcing ribs to key parts of the pallet (such as hinge connections, cavity edges, etc.) or using stronger materials.

[0056] Hinges 1-3 and 2-7 are preferably 90-degree self-locking folding support hinges. Since this is existing technology, its structural principle will not be described in detail. Its model number is CN-ZD0006.

[0057] The implementation principle of a plastic pallet with an anti-detachment buckle structure in this application embodiment is as follows: The user can rotate the side plate 4 to a vertical position using hinge 3, and then rotate the locking strip 6 to a vertical position using hinge 7. When adjusting the relative position between the pallets, the user can do so by sliding the slide bar 12 within the slide groove 13. The position of the locking strip 6 is adjusted by the drive assembly 8, so that it, together with the pallet and side plate 4, forms a closed enclosure structure. The limiting assembly 11 restricts the rotation of the crossbar 86 through the friction between the friction block 111 and the crossbar 86, ensuring the stability of the enclosure structure. When it is necessary to release the limit, the user can rotate the threaded rod 115 to push the friction block 111 to slide, thereby releasing the crossbar 86.

[0058] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
