[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-4 As shown, the plastic pallet for circular mechanical parts provided in the embodiment of the present application includes a pallet body 100, a coil spring 500, and a support plate 600. The pallet body 100 is the main structure of the plastic pallet and has a hollow structure with a cavity 200 defined therein. The upper surface of the pallet body 100 is also provided with a plurality of trapezoidal grooves 300, each extending along the length of the pallet body 100 and equidistantly distributed across the upper surface of the pallet body 100.

[0029] In this embodiment, the outer diameter of the upper opening of each trapezoidal groove 300 is larger than the outer diameter of the lower opening, so that circular mechanical parts can be placed and fixed in the trapezoidal groove 300. The bottom surface of each trapezoidal groove 300 is provided with a plurality of notches 400, which are evenly spaced along the length of the trapezoidal groove 300 and can be equal in width to the width of the trapezoidal groove 300.

[0030] A plurality of coil springs 500 are fixedly disposed in the cavity 200 of the disk body 100. Specifically, the bottom end of the coil spring 500 is fixedly connected to the bottom surface of the disk body 100, and the top end of the coil spring 500 passes through the notch 400 and is located outside the cavity 200 of the disk body 100. That is, the coil spring 500 is located below the notch 400, and the two are in a one-to-one correspondence.

[0031] like Figure 2As shown, the support plate 600 is disposed at the notch 400 of the trapezoidal groove 300. The support plate 600 is slidably disposed at the notch 400, and the bottom surface of the support plate 600 is fixedly connected to the top of the coil spring 500. The outer diameter and shape of the support plate 600 are adapted to the outer diameter and shape of the notch 400, so that the support plate 600 can squeeze the coil spring 500 and move up and down within the notch 400.

[0032] In the plastic pallet for circular mechanical parts provided in the embodiment of the present application, the circular mechanical part is placed in the trapezoidal groove 300 of the tray body 100 and placed on the support plate 600. Due to the weight of the circular mechanical part, the circular mechanical part presses downward on the support plate 600 and the coil spring 500, creating a height difference between the support plate 600 and the bottom surface of the trapezoidal groove 300, thereby securing the circular mechanical part in the space formed by the notch 400 and the support plate 600. This structural design can secure the circular mechanical part within the predetermined space, preventing it from shaking or colliding during transportation.

[0033] In some embodiments, the width between adjacent notches 400 within the trapezoidal groove 300 is equal to the width of the notches 400 themselves. This allows the circular mechanical components to be placed on the support plate 600 and between the support plates 600, thereby staggering the hollow rotor bearings vertically. This placement structure design not only improves the space utilization of the tray but also ensures the stability of the circular mechanical components.

[0034] In some embodiments, the lower surface of the disk body 100 is provided with an arc groove 700 adapted to a circular mechanical part, such as Figure 3 As shown, when multiple trays 100 are stacked one on top of the other, the upper tray 100 will abut against the circular mechanical parts fixed to the lower tray 100 through the arc groove 700. This not only ensures the stability of the circular mechanical parts during transportation, but also prevents the stacked trays from sliding relative to each other.

[0035] In some embodiments, a T-bar 800 is provided between adjacent notches 400. The T-bar 800 consists of a vertical portion 810 and a horizontal portion 900. The vertical portion 810 of the T-bar 800 is fixedly connected to the bottom surface of the trapezoidal groove 300, and the horizontal portion 900 of the T-bar 800 is inserted into the inner ring of the circular mechanical part, which can further ensure the stability of the circular mechanical part during transportation.

[0036] Preferably, if Figure 4As shown, the transverse portion 900 of the T-bar 800 includes a fixed rod 910, a connecting spring 920, and a movable rod 930. One end of the fixed rod 910 is fixedly connected to the vertical portion 810 of the T-bar 800, the other end of the fixed rod 910 is fixedly connected to the connecting spring 920, and the other end of the connecting spring 920 is fixedly connected to the movable rod 930. Pushing the movable rod 930 compresses the connecting spring 920, thereby facilitating movement of the movable rod 930 so that it can be inserted into the inner ring of the circular mechanical part.
