Description

Technical Field

[0001] This utility model relates to the technical field of plastic pallet devices, specifically a plastic pallet with a pearl cotton cushioning structure. Background Technology

[0002] Plastic pallets with pearl cotton cushioning structure are composite logistics packaging equipment that combines pearl cotton with plastic pallets. They are designed to improve the cushioning and shock absorption performance of traditional plastic pallets and are suitable for scenarios with high requirements for impact and vibration resistance during transportation.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a plastic tray with a pearl cotton cushioning structure.

[0026] According to the appendix Figure 1-7 As shown, the system includes a first plastic tray 1 and a second plastic tray 2. The second plastic tray 2 is installed at the bottom of the first plastic tray 1 via a connecting component 3. The first plastic tray 1 and the second plastic tray 2 are composed of the same components. The double-layer plastic tray can simultaneously support and place two sets of items. The first plastic tray 1 consists of a main tray 101, a secondary tray 102, and a connecting plate 103. The connecting plate 103 is fixedly installed on the outer wall of the main tray 101 and slidably connected to the bottom of the secondary tray 102. The outer walls on both sides of the secondary tray 102 are respectively provided with a first locking rod 4 and a second locking rod 5. One end of the first locking rod 4 and the second locking rod 5 passes through the outer wall of the secondary tray 102 and is inserted into the interior of the connecting plate 103. During use, the size of the two sets of plastic trays can be adjusted according to the size of the items to be placed, so that the two sets of plastic trays can support and place items of different sizes, and the position of the adjusted plastic trays can be limited and fixed by the two sets of locking rods.

[0027] Two sets of main trays 101 are each equipped with a drive assembly 6 on their outer walls. The two sets of drive assemblies 6 are connected by a connecting rod assembly 7. The drive assembly 6 is connected to a first locking rod 4. A transmission assembly 8 is provided between the first locking rod 4 and the second locking rod 5. The drive assembly 6 is connected to the second locking rod 5 through the transmission assembly 8. Items to be carried are placed inside the two sets of plastic trays, and the distance between the two sets of plastic trays can be adjusted according to the height of the items to meet usage needs. When adjusting the distance between the two sets of plastic trays, the first plastic tray 1 is pulled upwards, causing the telescopic rod 302 at the bottom of the first plastic tray 1 to slide inside the telescopic cylinder 303, thus achieving the work of adjusting the distance between the two sets of plastic trays. For details, please refer to the appendix. Figure 2 .

[0028] Multiple sets of locking holes 1031 are provided on the bottom outer wall of the connecting plate 103. The multiple sets of locking holes 1031 are equidistantly distributed along the axial direction of the connecting plate 103. The main support plate 101 and the auxiliary support plate 102 are respectively equipped with cushioning cotton 1021. The cushioning cotton 1021 structure can effectively disperse the vibration and collision energy during transportation and avoid damage caused by direct contact between the items and the rigid plastic frame. When adjusting the length of the two sets of plastic support plates, first pull the connecting rod assembly 7 outward, so that the drive assembly 6 on one side can simultaneously drive the two sets of first locking rods 4 to disengage from the inside of the connecting plate 103. With the cooperation of the transmission assembly 8, the other two sets of second locking rods 5 can be simultaneously driven to disengage from the inside of the connecting plate 103, and the position of the connecting plate 103 is no longer limited. Then, pull the main support plate 101 to one side, so that the length of the two sets of plastic support plates can be adjusted at the same time, improving the convenience of adjustment.

[0029] The connecting assembly 3 includes connecting ears 301, telescopic rods 302, and telescopic cylinders 303. Multiple sets of connecting ears 301 are fixedly installed on both sides of the outer wall of the main support plate 101 and the auxiliary support plate 102. The connecting ears 301 on both sides of the first plastic support plate 1 and the second plastic support plate 2 are symmetrically arranged. One end of the telescopic rod 302 and the telescopic cylinder 303 are fixedly connected to the upper and lower sets of connecting ears 301, respectively. The telescopic rod 302 is slidably connected inside the telescopic cylinder 303. After adjusting the size of the two sets of plastic support plates, the connecting rod assembly 7 is released. Under the reset of the drive spring 603, the two sets of first locking rods 4 and two sets of second locking rods 5 can be automatically driven to insert into the locking holes 1031 inside the connecting plate 103, thereby fixing the position of the two sets of connecting plates 103 after adjustment.

[0030] The drive assembly 6 includes a fixed frame 601, a drive rod 602, a drive spring 603, and a limiting plate 604. The fixed frame 601 is fixedly installed on the outer wall of the upper and lower sets of auxiliary support plates 102. The outer walls of the first locking rod 4 and the second locking rod 5 are respectively fixedly connected to the first mounting plate 401 and the second mounting plate 501. The first mounting plate 401 and the second mounting plate 501 are respectively attached to the outer walls of the two sides of the auxiliary support plate 102. By pulling the connecting rod assembly 7 outward, the drive rod 602 on one side of the two sets of auxiliary support plates 102 can simultaneously drive the first locking rod 4 to slide inside the fixed frame 601, and drive the drive spring 603 to deform. This allows the two sets of first locking rods 4 to simultaneously disengage from the two sets of connecting plates 103. With the cooperation of the transmission assembly 8, the other two sets of second locking rods 5 can simultaneously disengage from the connecting plates 103, improving the convenience of operation and facilitating the size adjustment and subsequent locking operation of the two sets of plastic support plates.

[0031] The drive rod 602 is slidably connected inside the fixed frame 601, and the limiting plate 604 is attached to the outer wall of the fixed frame 601. The two ends of the drive rod 602 are fixedly connected to the limiting plate 604 and the first mounting plate 401, respectively. The drive spring 603 is sleeved on the outer peripheral wall of the drive rod 602. One end of the drive spring 603 is fixedly connected to the first mounting plate 401, and the other end is fixedly connected to the inner wall of the fixed frame 601. The first locking rod 4 and the second locking rod 5 are respectively set on both sides of the connecting plate 103 and inserted into the inner sides of the connecting plate 103. This can improve the firmness of the installation and locking of the connecting plate 103. At the same time, it is easy to disengage the two sets of locking rods from the inner sides of the connecting plate 103 by simply pulling the connecting rod assembly 7 outward. The operation is simple, easy to adjust, and can ensure the firmness of the two sets of plastic trays after adjustment.

[0032] The connecting rod assembly 7 consists of a first connecting rod 701 and a second connecting rod 702. One end of the first connecting rod 701 and the second connecting rod 702 are respectively fixedly connected to the upper and lower limit plates 604. The first connecting rod 701 is slidably connected inside the second connecting rod 702. When adjusting the distance between the two sets of plastic support plates, the first connecting rod 701 can slide inside the second connecting rod 702, ensuring that the connecting rod assembly 7 and the two sets of drive assemblies 6 are always in a connected state.

[0033] The transmission assembly 8 includes a lower toothed plate 801, an upper toothed plate 802, and a drive gear 803. The lower toothed plate 801 and the upper toothed plate 802 are slidably connected to the bottom of the sub-support plate 102. One end of the lower toothed plate 801 and the upper toothed plate 802 are fixedly connected to the first mounting plate 401 and the second mounting plate 501, respectively. The drive gear 803 is rotatably connected to the bottom of the sub-support plate 102 and meshes between the lower toothed plate 801 and the upper toothed plate 802. When the connecting rod assembly 7 is pulled outward to slide the first locking rod 4 away from the inside of one side of the connecting plate 103, the first mounting plate 401 can drive the lower toothed plate 801 to slide inside the sub-support plate 102. Through the meshing action between the lower toothed plate 801, the upper toothed plate 802, and the drive gear 803, the upper toothed plate 802 can simultaneously drive the second locking rod 5 to disengage from the other side of the connecting plate 103, thereby realizing the disengagement of multiple sets of locking rods.
