Description

A modular egg storage and transportation pallet Technical Field

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

[0002] During storage and transportation, eggs are easily damaged by bumps, shaking, and other factors. Traditional egg trays have a fixed structure, and the material in contact with the eggs is relatively hard. Once the egg tray is formed, its shape and size are fixed. When eggs are placed in the tray, the contact force between the eggs and the tray is unevenly distributed. When the transport vehicle travels on bumpy roads, the eggs are prone to displacement and collision within the tray. In addition, the structural design of traditional egg trays is relatively simple. In order to reduce costs and material usage, their overall structure is relatively thin. For example, some egg trays made of thin cardboard or plastic are prone to overall denting and deformation after bearing a certain number of eggs. This leads to a reduction in the distance between the eggs, causing them to squeeze together and increasing the risk of breakage. During stacking or handling, uneven force can also cause deformation, making it impossible to effectively secure the eggs and affecting the normal use of the tray. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Referring to Figures 1-7, a modular egg storage and transportation pallet includes: a base plate 6, a top plate 1 on the top of the base plate 6, and the top plate 1 being fastened to the base plate 6;

[0031] One end of the bottom surface of the top plate 1 is provided with a first positioning groove 11, in which a detachable upper tray 4 is installed for easy replacement of a damaged upper tray 4. The upper tray 4 is provided with a plurality of inverted first egg slots 41, and the top of the plurality of first egg slots 41 is provided with a first elastic expansion hole 42 penetrating through the first egg slots 41. One end of the top surface of the bottom plate 6 is provided with a second positioning groove 61, in which a detachable lower tray 5 is installed. The lower tray 5 is provided with a plurality of second egg slots 51 corresponding one-to-one with the first egg slots 41. The bottom end of the second egg tray 51 is provided with a second elastic expansion hole 52 that penetrates the second egg tray 51. When the top plate 1 and the bottom plate 6 are fastened together, the bottom surface of the upper tray 4 abuts against the top surface of the upper tray 4, and an elastic storage space is formed between the first egg tray 41 and the second egg tray 51. In use, the top plate 1 and the bottom plate 6 are fastened together to form an overall external frame for carrying eggs for transportation and wrapping and protecting the eggs from bumps. The detachable upper tray 4 is installed in the first positioning groove 11 at one end of the bottom surface of the top plate 1. A detachable lower tray 5 is installed in the second positioning groove 61 at one end of the top surface. When the top plate 1 and the bottom plate 6 are fastened together, the bottom surface of the upper tray 4 and the top surface of the lower tray 5 abut against each other. The first egg groove 41 and the second egg groove 51 form an elastic storage space. After the egg is placed in the storage space, the upper and lower parts of the egg press the first egg groove 41 and the second egg groove 51 outward respectively. This causes the corresponding first elastic expansion hole 42 and second elastic expansion hole 52 on the first egg groove 41 and the second egg groove 51 to be subjected to an outward expansion force. Under the action of elasticity, they form a reverse fixing force on the egg, thereby wrapping the egg and playing a buffering role during transportation. This prevents the egg from shaking significantly during transportation and colliding with the tray, which could cause damage. This can minimize the risk of egg breakage during transportation. Furthermore, since the elastic component has a fatigue strength limit, by setting up modular and easily detachable upper tray 4 and lower tray 5 to be connected to the top plate 1 and the bottom plate 6 respectively, it is easy to replace the elastically failed components, thereby improving the service life of the tray.

[0032] The bottom surface of the base plate 6 is provided with a support structure protruding from the bottom surface of the base plate 6, and the top surface of the top plate 1 is provided with a recessed snap-fit ​​groove 9. The cross-sectional shape of the snap-fit ​​groove 9 matches the cross-sectional shape of the support structure. In use, the support structure is used to support and strengthen the load-bearing capacity of the base plate 6, and to support the weight of the entire pallet and the eggs, so that the eggs can be placed stably and transported, and the pallet can be prevented from deforming due to gravity during transportation. The cross-sectional shape of the snap-fit ​​groove 9 matches the cross-sectional shape of the support structure, so that the snap-fit ​​groove 9 between two adjacent pallets can form a stable limiting snap-fit ​​relationship with the support structure, thereby realizing the longitudinal stacking of multiple pallets.

[0033] Furthermore, the top surface of the first positioning groove 11 is deepened towards the inside of the top plate 1 and is provided with first storage holes 12 corresponding to a plurality of first egg slots 41. The plurality of first egg slots 41 are fitted and connected to the first storage holes 12. In use, the first storage holes 12 are set in a one-to-one correspondence with the first egg slots 41. The plurality of first storage holes 12 are used to separate the plurality of first egg slots 41 and to support the upper tray 4, thereby improving the connection stability between the upper tray 4 and the top plate 1, preventing the first egg slots 41 from shifting during use, and avoiding deformation of the upper tray 4 under force.

[0034] Furthermore, the depth of the first storage hole 12 is greater than the height of the first egg groove 41. The top of the interior of the first storage hole 12 is filled with a first buffer medium 13. The other end of the first buffer medium 13 abuts against the first elastic expansion hole 42 at the top of the first egg groove 41. During use, when the top of the egg is connected to the first egg groove 41, the first elastic expansion hole 42 is squeezed outward by the egg to adapt to the size of the egg, so that the upper part of the egg is wrapped and connected to the first egg groove 41. After the top of the egg passes through the first elastic expansion hole 42, it squeezes the first buffer medium 13. The first buffer medium 13 fills between the tip of the egg and the top wall of the first storage hole 12, preventing the egg from being shaken during transportation and collided with the top wall of the first storage hole 12, thus playing a buffering role.

[0035] Furthermore, the bottom surface of the second positioning groove 61 is deepened towards the interior of the base plate 6 and is provided with second storage holes 62 corresponding to a plurality of second egg slots 51. The plurality of second egg slots 51 are fitted and connected to the second storage holes 62. In use, the second storage holes 62 are set in a one-to-one correspondence with the second egg slots 51. The plurality of second storage holes 62 are used to separate the plurality of second egg slots 51 and to support the lower tray 5, thereby improving the connection stability between the lower tray 5 and the base plate 6, preventing the second egg slots 51 from shifting during use, and avoiding the lower tray 5 from undergoing concave deformation after bearing eggs, which would cause the plurality of second egg slots 51 to shift and approach each other, causing them to collide and break the eggs placed inside.

[0036] Furthermore, the depth of the second storage hole 62 is greater than the height of the second egg groove 51. The top of the interior of the second storage hole 62 is filled with a second buffer medium 63. The other end of the second buffer medium 63 abuts against the second elastic expansion hole 52 at the top of the second egg groove 51. In use, the bottom of the egg is connected to the second egg groove 51, and the second elastic expansion hole 52 is squeezed outward by the egg to adapt to the size of the egg, so that the lower half of the egg is wrapped and connected to the second egg groove 51. After the bottom tip of the egg passes through the second elastic expansion hole 52, it squeezes the second buffer medium 63. The second buffer medium 63 is filled between the bottom of the egg and the top wall of the second storage hole 62 to prevent the egg from shaking and colliding with the bottom wall of the second storage hole 62 during transportation, thus playing a buffering role.

[0037] Furthermore, the top plate 1 has connecting pins 3 at the four corners of its bottom surface, and the bottom plate 6 has connecting holes 7 at the four corners of its top surface that are connected to the connecting pins 3. Through the insertion and engagement of the connecting pins 3 and the connecting holes 7, the top plate 1 and the bottom plate 6 are tightly connected, preventing the top plate 1 and the bottom plate 6 from separating during transportation.

[0038] Furthermore, the connecting pin 3 includes a guide post 31 extending longitudinally downward along the bottom surface of the top plate 1. The diameter of the guide post 31 is the same as the diameter of the connecting hole 7. The guide post 31 can guide the top plate 1 and the bottom plate 6 to accurately align and insert the connecting pin 3 into the connecting hole 7 to form an integral connection, thereby improving the accuracy and reliability of the connection.

[0039] Furthermore, the middle section of the guide post 31 is provided with an elastic retaining ring 32 with a ring diameter larger than that of the guide post 31. The connecting hole 7 is provided with a limiting ring that abuts against the retaining ring 32. During the insertion stage of the guide post 31, the elastic retaining ring 32 at its middle end abuts against the limiting ring inside the connecting hole 7, thereby generating a contraction deformation that allows the elastic retaining ring 32 to pass through the limiting ring. After passing through the limiting ring, the elastic retaining ring 32 abuts against the limiting ring to form a locking structure that interlocks with each other, which can prevent the connecting pin 3 from loosening and falling off in the connecting hole 7, thereby ensuring a firm connection between the top plate 1 and the bottom plate 6.

[0040] Furthermore, both sides of the top plate 1 and the bottom plate 6 in the width direction are provided with openings 2 that are recessed towards the inside of the side end of the top plate 1 or the bottom plate 6. Support rods 21 are provided between the two sides of the openings 2. There is a gap between the support rods 21 and the side wall of the top plate 1 or the bottom plate 6. The support rods 21 are used to increase the structural strength of the pallet and prevent the pallet from deforming during transportation. The gap between the support rods 21 and the side wall of the top plate 1 or the bottom plate 6 can be used for gripping, so as to facilitate the handling of the whole pallet or to apply force to change the connection state between the top plate 1 and the bottom plate 6 by gripping the support rods 21 provided on the top plate 1 and the bottom plate 6 respectively.

[0041] Furthermore, the support structure includes two support ridges 8 distributed along the two diagonals of the base plate 6. The two support ridges 8 are integrally connected through the central intersection point. The two support ridges 8 are used to enhance the load-bearing capacity of the base plate 6, ensuring that the pallet can be placed stably and support the weight of the eggs. One end of the bottom surface of the two support ridges 8 is provided with an anti-slip strip 81. During use, the anti-slip strip 81 can prevent the pallet from sliding during handling or transportation, ensuring the stability of transportation.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
