[0028] like Figure 1-Figure 3 The self-locking pallet of the present invention is shown in FIG. 1 , which is mainly used for stably and conveniently placing and extracting goods in warehousing and logistics operations, and is particularly suitable for forklift and automation equipment operation scenarios. The pallet includes a pallet body 1 and a self-locking mechanism 2 .

[0029] The pallet body 1 is a U-shaped structure, with two sides for lifting goods, and a placement slot 11 is provided in the middle of the top of the two sides. The placement slot 11 opens upward, and the placement slot 11 is a through slot for placing cargo pillars, thereby supporting the cargo, and achieving stable lifting through the symmetrical design on both sides. The pallet body 1 is provided with a self-locking mechanism 2 on the outer side wall.

[0030] The self-locking mechanism 2 includes a mounting platform 5 , a first hanging ring 6 , a self-locking rod 13 , a sliding block 14 , a push rod 4 , a spring 7 , a single hook 10 and an axle pin 12 .

[0031] Among them: the front end of the outer side wall of the tray body 1 near the bottom is fixedly connected to the mounting platform 5, the mounting platform 5 is located obliquely below the placement groove 11, the first hanging ring 6 is fixedly connected to the mounting platform 5, the push rod 4 is provided with a second hanging ring 8, the spring 7 is horizontally arranged, and the hooks at both ends of the spring 7 are respectively hung on the first hanging ring 6 of the tray body mounting platform 5 and the second hanging ring 8 of the push rod 4. When the push rod 4 is away from the mounting platform 5, the spring 7 is stretched.

[0032] Design of push rod 4: push rod 4 is arranged horizontally, and a long hole is arranged at one end of self-locking rod 13. A slider 14 is connected to push rod 4, and slider 14 can be slidably connected in the long hole. When push rod 4 moves horizontally, self-locking rod 13 rotates around slider 14, and slider 14 moves in the long hole, thereby increasing the rotational freedom of self-locking rod 13 and avoiding rotation jam.

[0033] The single hook 10 and the axle pin 12 are arranged as follows: the axle pin 12 is located directly below the placement slot 11 and is fixedly connected to the outer wall of the pallet body 1. The bottom of the single hook 10 is rotatably connected to the axle pin 12, and the top is higher than the bottom of the placement slot 11, which can block the cargo support extending out of the placement slot 11 and play a limiting role. One side of the single hook 10 is open, and the other side is connected to the other end of the self-locking rod 13. When the self-locking rod 13 rotates, the single hook 10 is driven to rotate around the axle pin 12.

[0034] Top design of the single hook 10: The top of the single hook 10 is provided with an inclined surface inclined downward toward the opening side, so that when the cargo pillar falls, the cargo pillar can squeeze the inclined surface, causing the single hook 10 to rotate toward the self-locking rod 13 to achieve automatic unlocking.

[0035] In another embodiment of the present application, the push rod 4 is a straight rod structure, one end of which is located on the opposite side of the mounting platform 5 and extends out of the outer wall of the tray body 1, and a second hanging ring 8 is provided at the other end. The slider 14 is located at the other end of the push rod 4, and the push rod 4 is pulled outward to unlock the self-locking mechanism 2.

[0036] In another embodiment of the present application, the push rod 4 is a Z-shaped structure, the end of the bottom horizontal rod is located on the same side of the mounting platform 5 and extends out of the outer wall of the tray body 1, a stop platform 3 is provided at the end of the bottom horizontal rod, the second hanging ring 8 is located at the top of the vertical rod, and the slider 14 is located at the end of the top horizontal rod, pushing the push rod 4 inward to unlock the self-locking mechanism 2.

[0037] Self-locking mechanisms 2 are provided on the outer side walls of both sides of the pallet body 1, thereby improving the stability of cargo placement.

[0038] Cavities are provided on both sides of the tray body 1 for accommodating the self-locking mechanism 2. The self-locking mechanism 2 is located in the cavity, thereby effectively reducing bumps and accidental touches, increasing service life and reducing maintenance costs.

[0039] A limiting groove is provided on the middle top surface of the pallet body 1. The limiting groove has the same shape as the bottom of the cargo and is used to limit the cargo to prevent the cargo from shaking or tipping over after being placed. This design provides additional support for the cargo, thereby further improving the overall stability of the pallet.

[0040] A forklift access hole is provided at the middle bottom of the pallet body 1, so that the forklift can insert the pallet from the bottom and stably lift the goods. This design is particularly suitable for automated warehousing systems, which improves the compatibility and operating efficiency of the pallet with automated equipment.

[0041] The spring 7 and the push rod 4 are always arranged horizontally. Figure 2 As shown, when the spring 7 is in the reset state, the self-locking rod 13 is vertically arranged, and the top of the single hook 10 is located on the front side of the placement slot 11; Figure 3As shown, when the push rod 4 is moved away from the mounting platform 5, the bottom of the self-locking rod 13 rotates around the slider 14, and the top of the self-locking rod 13 drives the single hook 10 to rotate around the axle pin 12, and the slider 14 moves in the long hole, thereby increasing the rotation freedom of the self-locking rod 13 and avoiding rotation jamming. At this time, the top of the single hook 10 is located on the oblique side of the placement groove 11, and cannot limit the cargo pillar extending from the placement groove 11. The self-locking mechanism 2 is in an unlocked state, and the cargo can be taken out or put in; after releasing the push rod 4, the spring 7 drives the push rod 4 to reset, and then the single hook 10 resets. At this time, the top of the single hook 10 is located on the front of the placement groove 11, limiting the cargo pillar extending from the placement groove 11, realizing self-locking, and the overall linkage forms a self-locking mechanism 2.

[0042] like Figure 3 The figure shows a cross-sectional view of a self-locking pallet in a self-locking state. When storing goods, the cargo pillar is dropped into the placement groove 11 by manual or automated equipment. Under the action of gravity, the cargo pillar can squeeze the inclined surface, causing the single hook 10 to rotate toward the self-locking rod 13, and the goods fall. At this time, the stopper 9 drives the self-locking rod 13 to rotate, and the push rod 4 connected by the slider 14 moves and retracts accordingly, and the spring 7 stretches and extends.

[0043] like Figure 2-Figure 3 As shown, after the cargo falls and is placed, there is no external force acting on it, at which time the stretched spring 7 is reset, the push rod 4 moves out accordingly, the self-locking rod 13 connected by the slider 14 moves accordingly, the linkage shaft pin 12 rotates, the single hook 10 is reset, and the self-locking mechanism 2 is locked.

[0044] like Figure 1-Figure 3 As shown, the present invention needs to cooperate with the transfer equipment when in use. The direction of the push rod 4 is consistent with the direction of travel. The push rod 4 is gradually pushed toward the transfer equipment. When the goods are transported to the specified position, the push rod 4 is pushed in the opposite direction by the power of the transfer equipment that transports the pallet body 1. The self-locking rod 13 is driven to move through the slider 14, the axle pin 12 rotates, and the single hook 10 rotates to realize the automatic unlocking function, so that the goods can be taken out.

[0045] When the push rod 4 is pushed inward, the spring 7 is stretched accordingly. After the goods are taken out, the pallet body 1 leaves the transfer equipment. At this time, there is no external force, and the spring 7 automatically resets, driving the self-locking mechanism 2 to reset and self-lock again.

[0046] The application scenarios and advantages of the self-locking pallet described in this application: Automation adaptability: This pallet can be used in conjunction with automated warehousing and retrieval equipment. Through the design of the push rod 4 and the spring 7, the goods can be automatically unlocked and reset at a specific position, reducing manual intervention and improving logistics automation efficiency.

[0047] High stability: Self-locking mechanisms 2 are provided on both sides of the pallet body 1. After the goods are placed, the self-locking structure limits and fixes the cargo pillars, effectively preventing the goods from shaking and tipping over during transportation.

[0048] Safety and durability: The cavity design of the tray body 1 can prevent the self-locking mechanism 2 from being exposed, reduce damage caused by external force or bumps, extend the service life of the self-locking tray, and ensure safe use in various complex environments.
