Description
Technical Field
[0001] The utility model relates to the field of pallets, in particular to a molded pallet with enhanced lateral strength. Background Art
[0002] Existing molded pallets are rectangular in shape. During transportation, a fork is inserted under the pallet from one side and then lifts the pallet together with the goods on top.
[0003] In actual use, it is impossible for the operator to ensure that the fork does not touch the pallet every time before inserting it under the pallet, so the fork often collides with the side of the pallet.
[0004] The existing pallet structure design direction is designed to withstand the vertical gravity of the cargo. For example, the foot pier at the corner is directly connected to the foot pier at the opposite side through reinforcing ribs. This design has a good load-bearing capacity, but the strength of the longer reinforcing ribs at the side is low, which is not conducive to bearing lateral impact force.
[0005] Currently, the design for lateral collision usually adopts the method of thickening the lateral reinforcement ribs and the thickness of the load-bearing part. However, the method of thickening the pallet performs poorly in improving the pallet's ability to resist lateral collision, and requires more waste of raw materials, resulting in an increase in the material cost of the pallet.

[0010] Based on the above technical solution, the bearing part is formed with internal reinforcing ribs, the foot pier in the middle of the bearing part is connected to one end of multiple internal reinforcing ribs, and the end of the internal reinforcing rib away from the foot pier in the middle is connected to the foot pier at the corner.
[0011] Based on the above technical solution, the bearing portion is formed with a first reinforcing rib, the foot pier at the side is connected to the first reinforcing rib near the corner, and one end of the first reinforcing rib away from the foot pier at the side is closed.
[0012] Based on the above technical solution, the first reinforcing rib and the first side reinforcing rib are located on the same straight line or are parallel to each other.
[0013] Based on the above technical solution, the bearing portion is formed with a second reinforcing rib, the side foot pier close to the middle foot pier and / or the foot pier away from the middle foot pier is connected to the second reinforcing rib, the corner foot pier away from the middle foot pier is connected to the second reinforcing rib, and the second reinforcing rib is closed at one end away from the foot pier connected thereto.

[0031] Preferably, the side edge 11 is a straight line or an arc.
[0032] Preferably, the bearing portion 1 and the footrest 2 are integrally molded from wood fiber.
[0033] On the basis of the above technical solution, the side reinforcing rib 3 includes a first side reinforcing rib 31, a second side reinforcing rib 32 and a third side reinforcing rib 33. The two ends of the third side reinforcing rib 33 are respectively connected to the second side reinforcing rib 32. The two ends of the first side reinforcing rib 31 are respectively connected to one end of the second side reinforcing rib 32 away from the third side reinforcing rib 33 and the foot pier 2 at the corner 12. The third side reinforcing rib 33 is located on the inner side of the foot pier 2 at the side 11. The first side reinforcing rib 31 directly bears the force of the lateral collision. The length of the first side reinforcing rib 31 is smaller than the distance from the foot pier 2 at the corner 12 to the foot pier 2 at the side 11. Compared with the reinforcing ribs in the prior art that directly connect the foot pier 2 at the corner 12 and the foot pier 2 at the side 11, the smaller length of the first side reinforcing rib 31 brings better strength. Among them, the second side reinforcing rib 32 and the third side reinforcing rib 33 are at the bending part.
[0034] Preferably, the first side reinforcing rib 31 , the second side reinforcing rib 32 and the third side reinforcing rib 33 are straight-line or arc-line shaped.
[0035] On the basis of the above technical solution, the first side reinforcing rib 31 is parallel to the third side reinforcing rib 33, and the first side reinforcing rib 31 is parallel to the side edge 11, which is beneficial to enhancing the bending strength of the pallet; the angle between the second side reinforcing rib 32 and the first side reinforcing rib 31 is 90 degrees to 130 degrees, and the effect of the second side reinforcing rib 32 is better at this angle. It should be noted that when the first side reinforcing rib 31 and the third side reinforcing rib 33 are parallel, the angle between the third side reinforcing rib 33 and the second side reinforcing rib 32 is the same as the angle between the second side reinforcing rib 32 and the first side reinforcing rib 31. The second side reinforcing rib 32 bears the lateral force and the force of the first side reinforcing rib 31, and transmits the force to the third side reinforcing rib 33.
[0036] Preferably, the included angle between the second side reinforcing rib 32 and the first side reinforcing rib 31 is 118 degrees.

[0039] Based on the above technical solution, the first reinforcing rib 5 and the first side reinforcing rib 31 are located on the same straight line or are parallel to each other.
[0040] Based on the above technical solution, the bearing portion 1 is formed with a second reinforcing rib 6, the foot pier 2 at the side 11 is connected to the second reinforcing rib 6 at a position close to the middle foot pier 2 and / or away from the middle foot pier 2, the foot pier 2 at the corner 12 is connected to the second reinforcing rib 6 away from the middle foot pier 2, and the second reinforcing rib 6 is closed at one end away from the foot pier 2 connected thereto.
[0041] On the basis of the above technical solution, the bearing portion 1 is formed with a guide protrusion 7, the guide protrusion 7 is connected with the first side reinforcing rib 31, and a guide surface 71 is formed on the side of the guide protrusion 7 close to the side edge 11, and the lower side of the guide surface 71 is inclined away from the side edge 11. The inclined guide surface 71 is used to guide the fork of the forklift to prevent the fork from directly contacting the side of the reinforcing rib that is close to the vertical direction, causing the fork to pierce the first side reinforcing rib 31.
[0042] On the basis of the above technical solution, the bearing part 1 is formed with a limiting protrusion 8 and a limiting groove 81.

The limiting protrusion 81 is connected with the inner reinforcing rib 4, and the bottom surface of the limiting protrusion 81 and the bottom surface of the inner reinforcing rib 4 are located in the same plane, thereby increasing the contact area between the lower end of the pallet and the fork, reducing the pressure, and avoiding damage to the pallet.
[0043] Based on the above technical solution, there are four sides 11 and four corners 12, each corner 12 has a foot pier 2, and all the foot piers 2 are arranged in a lattice; the foot pier 2 is integrally formed with the bearing portion 1.

Preferably, the spacing between the lower protrusions 21 is greater than the spacing between the upper protrusions.
[0046] When in use, the cargo is placed on the load-bearing part 1, and the lower end of the footrest 2 is in contact with the ground. Each fork is guided by the corresponding guide surface 71 and is under the pallet. The forks move upward, and each fork contacts the lower end of three side reinforcing ribs 3 and two inner reinforcing ribs 4. The side reinforcing ribs 3 and the inner reinforcing ribs 4 support the part of the pallet that is not in contact with the forks, so as to prevent the part of the pallet that is not in contact with the forks from bending due to the pressure of the cargo without support.
[0047] When the fork collides with the side edge 11 or the side reinforcing rib 3 at the non-guide surface 71, the side reinforcing rib 3 is stressed to prevent the pallet from being changed or damaged.
[0048] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
