Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example:
[0021] Please see Figures 1 to 2 This utility model provides a technical solution:
[0022] A cushioned metal tray includes a connecting plate 1, a base 2, a cushioning assembly 3, and a carrying plate 4. At least two bases 2 are arrayed between two connecting plates 1. The connecting plates 1 are used to connect all the bases 2 in series, so that the bases 2 can be fixed to the connecting plates 1. The cushioning assembly 3 is provided inside the base 2, wherein:
[0023] The buffer assembly 3 includes a secondary buffer assembly 31, a primary buffer assembly 32, and a tertiary buffer assembly 33. The secondary buffer assembly 32 is located inside the base 2, the primary buffer assembly 32 is located at the upper end of the lifting part of the primary buffer assembly 32, and the tertiary buffer assembly 33 is located between the secondary buffer assembly 31 and the base 2. The buffer assembly 3 adopts a multi-stage buffering form to reduce the impact force when goods are placed on the pallet.
[0024] The loading plate 4 is located at the buffer end of the primary buffer assembly 32. The loading plate 4 serves as the loading end of the tray.
[0025] In a preferred embodiment, the secondary buffer assembly 31 includes a movable support plate 311 and a spring I 312. The movable support plate 311 is vertically and movably installed in the mounting groove of the base 2. The movable support plate 311 forms a vertical sliding pair in the mounting groove of the base 2. The spring I 312 is provided between the movable support plate 311 and the lower end face of the mounting groove of the base 2.
[0026] In a preferred embodiment, the primary buffer assembly 32 includes a movable block 321, a passage groove 322, and a spring II 323. The movable block 321 is vertically movably mounted within the passage groove 322 on the movable support plate 311. The movable block 321 moves vertically within the passage groove 322. When the carrying plate 4 moves downwards under the weight of the cargo, the movable block 321 compresses the spring II 323 downwards, achieving primary buffering. When the movable block 321 moves to be flush with the upper surface of the movable support plate 311, the carrying plate 4 pushes the movable support plate 311 downwards within the base 2, compressing the spring I 312. At this point, secondary buffering begins. The spring II 323 is located within the passage groove 322 of the movable block 321 and is connected to the slider 321.
[0027] In a preferred embodiment, the three-stage buffer assembly 33 includes a movable plate 331 and a cross-shaped bracket 332. The movable plate 331 is vertically movable within the passage groove 322, forming a vertical sliding joint within the passage groove 322. The movable plate 331 is connected to a spring II 323, which is located within the passage groove 322 and connected at both ends to the movable plate 331 and the movable block 321, respectively. The base 2 has a cross-shaped bracket 332 inside, with its top facing the movable plate 331 and the passage groove 322. The top of the cross-shaped bracket 332 can enter the passage groove 322. When the movable support plate 311 moves downward, causing the top of the cross-shaped bracket 332 to enter the passage groove 322 and contact the movable plate 331, and the movable support plate 311 continues to be pressed down, the top of the cross-shaped bracket 332 will push the movable plate 331 upward to compress the spring II 323, thus achieving the purpose of three-stage buffering.
[0028] In a preferred embodiment, a baffle 3221 is provided inside the groove 322 to restrict the downward movement of the movable plate 331. By providing the baffle 3221, the spring II 323 can be compressed during the first-stage buffering.
[0029] In a preferred embodiment, the horizontally positioned straight plate portion of the cross-shaped bracket 332 is parallel to the bottom of the movable support plate 311, and the horizontally positioned straight plate portion cannot pass through the through slot 322. When the movable support plate 311 moves to the top and bottom of the cross-shaped bracket 332, the side brackets of the cross-shaped bracket 332 will abut against the movable support plate 311, thereby preventing the movable support plate 311 from continuing to move downward. At this time, the elastic buffer becomes a rigid support. This can prevent the springs I 312 and II 323 from being compressed to their maximum elastic modulus and causing spring failure.
[0030] The working principle of this utility model:
[0031] In use, when the transported goods are placed on the carrying plate 4, the carrying plate 4 moves downwards under the weight of the goods, causing the movable block 321 to compress the spring II 323, achieving primary buffering. When the movable block 321 moves to be flush with the upper surface of the movable support plate 311, the carrying plate 4 pushes the movable support plate 311 downwards within the base 2, compressing the spring I 312, thus initiating secondary buffering. When the movable support plate 311 moves downwards, causing the top of the cross-shaped bracket 332 to enter the slot 322 and contact the movable plate 331, it continues to press down on the movable support plate 311. At this point, the top of the cross-shaped bracket 332 pushes the movable plate 331 upwards, compressing the spring II 323, thus achieving tertiary buffering. When the movable support plate 311 moves to the top and bottom of the cross-shaped bracket 332, the side brackets of the cross-shaped bracket 332 will abut against the movable support plate 311, preventing it from moving further downwards. At this point, the elastic buffering becomes rigid support. This can prevent springs I 312 and II 323 from being compressed to their maximum elastic modulus, which would cause the springs to fail.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
