Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and in particular to a double-layer composite blister tray. Background Technology

[0002] In the current logistics, warehousing and packaging industry, pallets are key tools for carrying and transporting goods, and their design and function directly affect the efficiency of stacking, handling and storing goods; however, traditional pallets mostly have problems such as fixed height and poor air permeability, making it difficult to meet the diverse needs of modern warehouse management;

[0003] First, the height of traditional pallets is usually fixed, which limits their flexible application in different scenarios. In warehouse space, the different heights of shelves and storage requirements require pallets to have adjustable height characteristics in order to make more efficient use of space and increase storage density. However, existing fixed-height pallets cannot adapt to this change, resulting in low warehouse space utilization and increased operating costs for enterprises.

[0004] Secondly, traditional pallets have significant shortcomings in terms of breathability; many pallets adopt a closed design and lack sufficient ventilation gaps or holes, making it easy for items to become damp, moldy, or deteriorate during storage; especially in humid or temperature-fluctuating environments, such poorly breathable pallets will exacerbate the quality problems of the items and cause economic losses to enterprises.

[0005] Therefore, it is necessary to provide a new double-layer composite blister tray to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a double-layer composite blister tray.

[0007] The double-layer composite blister tray provided by this utility model includes: a base plate, a ventilation seam, and a lifting assembly. A liftable top plate is installed on the top of the base plate. Supports are fixedly connected at equal intervals to the bottom of the base plate. Placement slots for storing the supports are opened at equal intervals on the top of the top plate. Ventilation seams for ventilation are opened at equal intervals inside the placement slots. A connecting protrusion is fixedly connected to the top of the top plate. A lifting assembly for adjusting the distance between the base plate and the top plate is installed between the base plate and the top plate.

[0008] Preferably, the lifting assembly includes: a first connecting rod, a second connecting rod, an upper crossbar, a lower crossbar, and a threaded rod. The top of the base plate is symmetrically and rotatably connected to the first connecting rod, and the bottom of the top plate is symmetrically and rotatably connected to the second connecting rod. The two first connecting rods and the two second connecting rods are rotatably connected at their middle parts. The ends of the two first connecting rods away from the base plate are rotatably connected to the upper crossbar, and the ends of the two second connecting rods away from the top plate are rotatably connected to the lower crossbar. The upper crossbar is slidably connected to the bottom of the top plate, and the lower crossbar is slidably connected to the top of the base plate. The top of the base plate is rotatably connected to the threaded rod, and the threaded rod is threadedly connected to the middle part of the lower crossbar.

[0009] Preferably, one end of the threaded rod has an internal hexagonal groove.

[0010] Preferably, both sides of the bottom plate and the top plate are provided with grooves, and nuts are fixedly connected inside the grooves, one of which is threaded with a bolt.

[0011] Preferably, a wear-resistant bearing is provided at the rotating connection between connecting rod one and connecting rod two to reduce frictional loss of the connecting rod during rotation, thereby improving the service life and rotational flexibility of the connecting rod.

[0012] Preferably, the outer surface of the nut is provided with an anti-rust coating to improve the nut's corrosion resistance and extend its service life.

[0013] Compared with related technologies, the double-layer composite blister tray provided by this utility model has the following beneficial effects:

[0014] Height adjustable, high space utilization:

[0015] This utility model's pallet features an innovative lifting component design, allowing the top plate to move vertically relative to the bottom plate, thus enabling flexible height adjustment.

This maximizes storage space utilization, reduces waste, and lowers operating costs for businesses.

[0016] Good breathability and strong protection for items:

[0017] The placement slots on the top plate are equidistantly spaced with ventilation gaps. These gaps not only ensure air circulation and effectively prevent quality loss of items due to moisture, mold, or deterioration during storage, but also enhance the ventilation performance of the tray, keeping the items dry and clean and extending their storage life.

[0018] Stable structure, safe and reliable:

[0019] The pallet is made of double-layer composite thermoforming material, combined with internal reinforced steel pipes, which greatly enhances the overall structural strength and stability. Meanwhile, the linkage mechanism and threaded rod in the lifting assembly are rationally designed, and wear-resistant bearings are installed at the rotating connections to reduce friction loss, improve service life, and ensure the pallet's smoothness and safety during lifting.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1-3A double-layer composite blister tray includes: a base plate 1, ventilation seams 5, and a lifting assembly. A liftable top plate 2 is mounted on the top of the base plate 1. Supports 3 are fixedly connected at equal intervals to the bottom of the base plate 1. Placement slots 4 for accommodating the supports 3 are equidistantly opened on the top of the top plate 2. Ventilation seams 5 for ventilation are equidistantly opened inside the placement slots 4. Connecting protrusions 6 are fixedly connected to the top of the top plate 2. A lifting assembly for adjusting the distance between the base plate 1 and the top plate 2 is installed between the base plate 1 and the top plate 2. Both sides of plate 1 and top plate 2 are provided with grooves 13, and nuts 14 are fixedly connected inside the grooves 13. One of the nuts 14 is threaded with a bolt 15. Steel pipes for reinforcement are installed inside the bottom plate 1 and top plate 2 respectively. Wear-resistant bearings are provided at the rotating connection of connecting rod 1 7 and connecting rod 2 8 to reduce friction loss of the connecting rod during rotation, improve the service life of the connecting rod and the flexibility of rotation. The outer surface of the nut 14 is provided with an anti-rust coating to improve the corrosion resistance of the nut 14 and extend its service life.

[0027] Please see Figure 2-3 The lifting assembly includes: connecting rod 7, connecting rod 8, upper crossbar 9, lower crossbar 10, and threaded rod 11. Connecting rod 7 is symmetrically and rotatably connected to the top of the base plate 1, and connecting rod 8 is symmetrically and rotatably connected to the bottom of the top plate 2. The two connecting rods 7 and the two connecting rods 8 are rotatably connected in the middle. The upper crossbar 9 is rotatably connected to the end of the two connecting rods 7 away from the base plate 1, and the lower crossbar 10 is rotatably connected to the end of the two connecting rods 8 away from the top plate 2. The upper crossbar 9 is slidably connected to the bottom of the top plate 2, and the lower crossbar 10 is slidably connected to the top of the base plate 1. The threaded rod 11 is rotatably connected to the top of the base plate 1, and the threaded rod 11 is threadedly connected to the middle of the lower crossbar 10. One end of the threaded rod 11 is provided with an internal hexagonal groove 12.

[0028] It should be noted that:

[0029] Due to the cross-connection of the linkage mechanism, when the lower crossbar 10 moves, it drives the second connecting rod 8 and the first connecting rod 7 to rotate. This rotation further propels the top plate 2 to move up and down. Specifically, when the threaded rod 11 rotates clockwise, the lower crossbar 10 moves towards one end of the threaded rod 11, pushing the second connecting rod 8 and the first connecting rod 7 to rotate, thereby raising the top plate 2. Conversely, when the threaded rod 11 rotates counterclockwise, the lower crossbar 10 moves towards the other end of the threaded rod 11, the second connecting rod 8 and the first connecting rod 7 rotate in the opposite direction, and the top plate 2 descends.

[0030] The working principle of the double-layer composite blister tray provided by this utility model is as follows:

[0031] Working principle of the liftable roof panel 2:

[0032] The pallet consists of a base plate 1 and a top plate 2. The top plate 2 is installed on top of the base plate 1 via a lifting assembly and can move up and down as needed.

[0033] The lifting range of the top plate 2 is determined by the structural design of the lifting assembly and the degree of rotation of the threaded rod 11;

[0034] Working principle of the lifting assembly:

[0035] The lifting assembly is the core of the pallet height adjustment, and it is mainly composed of components such as connecting rod 1 (7), connecting rod 2 (8), upper crossbar (9), lower crossbar (10), and threaded rod (11).

[0036] Linkage 7 and link 8 are rotatably connected to the bottom plate 1 and the top plate 2 at their respective positions, forming a cross linkage mechanism. This design allows link 7 and link 8 to cooperate with each other during rotation, jointly pushing the top plate 2 to rise and fall.

[0037] The lower crossbar 10 is rotatably connected to the end of the connecting rod 2 away from the top plate 2, while the upper crossbar 9 is rotatably connected to the end of the connecting rod 1 away from the bottom plate 1; this connection method enables the linkage mechanism to maintain a certain stability and coordination during movement.

[0038] The threaded rod 11 is rotatably connected to the top of the base plate 1 and is threadedly connected to the middle of the lower crossbar 10; when the threaded rod 11 rotates, the lower crossbar 10 will move along the axial direction of the threaded rod 11 due to the action of the thread.

[0039] Due to the cross-connection of the linkage mechanism, when the lower crossbar 10 moves, it will drive the second link 8 and the first link 7 to rotate. This rotation will further drive the top plate 2 to move up and down. Specifically, when the threaded rod 11 rotates clockwise, the lower crossbar 10 moves towards one end of the threaded rod 11, pushing the second link 8 and the first link 7 to rotate, thereby causing the top plate 2 to rise. Conversely, when the threaded rod 11 rotates counterclockwise, the lower crossbar 10 moves towards the other end of the threaded rod 11, the second link 8 and the first link 7 rotate in the opposite direction, and the top plate 2 descends.

[0040] Operation and adjustment:

[0041] Users can adjust the height of the tray by rotating the threaded rod 11; one end of the threaded rod 11 has an internal hexagonal groove 12, which makes it convenient to use tools such as an internal hexagonal wrench to rotate it.

[0042] During the adjustment process, the upper crossbar 9 and the lower crossbar 10 slide on the top plate 2 and the bottom plate 1 respectively to ensure that the top plate 2 can be raised and lowered smoothly.

[0043] Meanwhile, the design of the connecting protrusion 6 on the top plate 2 and the support 3 on the bottom plate 1 enables the top plate 2 to maintain a stable posture during the lifting process, avoiding tilting or swaying.

[0044] Additional features and design:

[0045] Wear-resistant bearings and other components can be installed at the rotating connection between connecting rod 7 and connecting rod 8 to reduce friction loss and improve rotational flexibility.

[0046] The outer surface of the nut 14 may be provided with protective measures such as an anti-rust coating to improve corrosion resistance and extend service life.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
