Description

Technical Field

[0001] The utility model belongs to the technical field of pallets, and in particular relates to a stable pallet structure of a packaging box. Background Art

[0002] A pallet is a medium that turns static goods into dynamic goods. It is a cargo platform and a movable platform, or a movable ground. It is also often used as the bottom plate of a packaging box.

[0003] The pallets commonly used as the bottom plate of the packaging box are mostly just a rectangular block with forklift forks. Such pallets do not have good shock absorption function, and thus cannot guarantee that the carried goods can be effectively protected when they are shocked during transportation, which may cause losses. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a stable pallet structure for a packaging box.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A stable pallet structure of a packaging box, comprising a bottom plate, a plurality of sleepers are installed in parallel at the bottom of the bottom plate, a pallet is installed on the upper side of the bottom plate, a plurality of first spring shock absorbers are installed between the bottom plate and the pallet, the first spring shock absorbers are evenly installed between the bottom plate and the pallet, the first spring shock absorbers are installed in a filling manner between the bottom plate and the pallet, and right-angle fixing plates are installed at the four corners of the top of the pallet;

[0007] Two positioning mechanisms are installed between the bottom plate and the support plate, and the two positioning mechanisms are symmetrically arranged between the bottom plate and the support plate;

[0008] The positioning mechanism includes an I-shaped block fixedly installed on the base plate, the I-shaped block is integrally connected with a fixed block, second spring shock absorbers are symmetrically installed on both sides of the I-shaped block, two second spring shock absorbers are connected with L-shaped blocks, two third spring shock absorbers are parallelly installed on the side of the I-shaped block, the two third spring shock absorbers are connected with an M-shaped block, the M-shaped block is integrally connected with an ear plate, the ear plate is perpendicular to the M-shaped block, and the L-shaped block and the ear plate are fixedly installed on the lower side of the support plate.

[0009] It is further defined that the first spring shock absorber, the second spring shock absorber and the third spring shock absorber have the same specifications and models, and are all JW130-65-145-2 spring shock absorbers. Such a design allows spring shock absorbers to be purchased directly, which is conducive to batch production of spare parts.

[0010] It is further defined that the four corners and the center of the base plate and the support plate are provided with through holes corresponding to each other, and the gaps between the through holes are matched with pins. With this design, by inserting the pins into the through holes, whether the base plate and the support plate are parallel to each other can be determined by whether the pins can be fully inserted, thereby achieving the purpose of checking whether the support plates are parallel after the support plates are fixed.

[0011] It is further defined that the base plate and the support plate are both provided with avoidance openings corresponding to the positions of the positioning mechanism. Such a design facilitates the insertion of a screwdriver when installing the positioning mechanism.

[0012] It is further defined that the bottom plate is installed with side plates. Such a design can limit the edge position of the support plate so that when the support plate is subjected to force, it can only perform vertical translation to ensure stability.

[0013] The beneficial effects of adopting the utility model are:

[0014] With the structural design of the utility model, under the effect of the first spring shock absorber, the support plate can effectively buffer when subjected to force, prevent hard collision when subjected to force, effectively protect the carried goods, and enhance the safety effect of the goods;

[0015] By adopting the structural design of the utility model, under the effect of the positioning mechanism, the support plate is stably installed and does not easily move around, and the force is concentrated on the first spring shock absorber to ensure the stability of use.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 to Figure 4 As shown, a stable pallet structure of a packaging box of the utility model comprises a bottom plate 1, a plurality of sleepers 2 are installed in parallel at the bottom of the bottom plate 1, a pallet 3 is installed on the upper side of the bottom plate 1, a plurality of first spring shock absorbers 4 are installed between the bottom plate 1 and the pallet 3, the first spring shock absorbers 4 are evenly installed between the bottom plate 1 and the pallet 3, the first spring shock absorbers 4 are installed in a filling manner between the bottom plate 1 and the pallet 3, and right-angle fixing plates 5 are installed at the four corners of the top of the pallet 3;

[0026] Two positioning mechanisms 6 are installed between the bottom plate 1 and the support plate 3, and the two positioning mechanisms 6 are symmetrically arranged between the bottom plate 1 and the support plate 3;

[0027] The positioning mechanism 6 includes an I-shaped block 61 fixedly installed on the base plate 1, the I-shaped block 61 is integrally connected with a fixed block 62, second spring shock absorbers 63 are symmetrically installed on both sides of the I-shaped block 61, the two second spring shock absorbers 63 are both connected with an L-shaped block 64, two third spring shock absorbers 65 are installed in parallel on the side of the I-shaped block 61, the two third spring shock absorbers 65 are connected with an M-shaped block 66, the M-shaped block 66 is integrally connected with an ear plate 67, the ear plate 67 is perpendicular to the M-shaped block 66, and the L-shaped block 64 and the ear plate 67 are fixedly installed on the lower side of the support plate 3.

[0028] In this embodiment, when a stable pallet structure of a packaging box is used, the sleepers 2 are evenly arranged in parallel and installed on the lower side of the bottom plate 1, and then one end of the first spring shock absorber 4 is installed on the bottom plate 1, and then the support plate 3 is horizontally placed on the other end of the first spring shock absorber 4, and the first spring shock absorber 4 is fixed;

[0029] The I-shaped block 61 is installed on the bottom plate 1, and then the L-shaped blocks 64 on both sides are installed on the pallet 3. Under the effect of the second spring shock absorber 63, the bottom plate 1 completes the pulling of the pallet 3 on both sides of the I-shaped block 61, so that the pallet 3 is not easy to move in these two directions. Then, the M-shaped block 66 is installed on the pallet 3 through the ear plate 67. Under the effect of the third spring shock absorber 65 on both sides, the bottom plate 1 pulls and limits the pallet 3 on the other two sides, that is, under the effect of the positioning mechanism 6, the displacement of the peripheral side of the pallet 3 is limited, so that most of the force of the pallet 3 when carrying goods acts on the first spring shock absorber 4 on the lower side, thereby ensuring the stability of the pallet 3;

[0030] After placing the goods on the pallet 3, use the right-angle fixing plate 5 to fix the four corners of the goods, and fix the right-angle fixing plate 5 on the pallet 3. The right-angle fixing plate 5 can be fixed with self-tapping screws to adapt to the four corners of goods of different specifications.

[0031] Preferably, the first spring shock absorber 4, the second spring shock absorber 63 and the third spring shock absorber 65 have the same specifications and models, all of which are JW130-65-145-2 spring shock absorbers. Such a design allows the spring shock absorbers to be purchased directly, which is conducive to batch spare parts. In fact, the specifications and models of the first spring shock absorber 4, the second spring shock absorber 63 and the third spring shock absorber 65 can also be considered according to specific circumstances.

[0032] Preferably, the four corners and the center of the base plate 1 and the support plate 3 are provided with through holes 7 that correspond to each other, and the gaps of the through holes 7 are matched with pins. With this design, by inserting the pins into the through holes 7, it is possible to determine whether the base plate 1 and the support plate 3 are parallel to each other by whether the pins can be fully inserted, thereby achieving the purpose of checking whether the support plates 3 are parallel after the support plates 3 are fixed. In fact, measures to check whether the support plates 3 are parallel after the support plates 3 are fixed can also be considered according to specific circumstances.

[0033] Preferably, both the base plate 1 and the support plate 3 are provided with an avoidance opening 8 corresponding to the position of the positioning mechanism 6. Such a design facilitates the insertion of a screwdriver when installing the positioning mechanism 6. In fact, a structure that facilitates the installation of the positioning mechanism 6 can also be considered according to specific circumstances.

[0034] Preferably, the bottom plate 1 is installed with a side plate 9. Such a design can limit the edge position of the support plate 3 so that when the support plate 3 is subjected to force, it can only perform vertical translation to ensure stability. In fact, the height dimension of the side plate 9 can also be considered according to specific circumstances.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
