The rear side of the placing cabinet 10 is rotatably connected with symmetrically distributed cabinet doors 11. Every two symmetrically distributed cabinet doors 11 seal the placing spaces at the same height. The cabinet doors 11 are opened A first groove 111 is provided for increasing the force application area, a tray 13 for storing articles is placed inside the placement space, a second groove 131 is provided on the tray 13 for increasing the force application area, the upper and lower sides of the cabinet door 11 are connected with fan gears 12 by welding, the left and right sides of the tray 13 are connected with symmetrically distributed racks 14 by welding, the adjacent fan gears 12 and racks 14 are meshed with each other, left and right slide grooves 16 are provided inside the placement cabinet 10, a slider 15 is slidably connected inside the slide groove 16, the slider 15 is installed and connected to the tray 13 in contact with each other through a connecting piece, and the length of the slide groove 16 is shorter than the length of the placement cabinet 10, so that the slider 15 is limited inside the placement cabinet 10.

[0029] Another aspect of the utility model provides a delivery robot, comprising a weighing device, wherein the weighing device is arranged on the delivery robot.

[0030] A delivery robot, see Figure 1-Figure 2 As shown, it includes a base 1, a moving wheel 2, a smart display screen 3, a camera 4, a first spring 501 and a buffer sheet 5. The lower part of the base 1 is connected to the moving wheel 2 by bolts, and the upper front side of the base 1 is connected to the smart display screen 3 and the camera 4 by bolts. The camera 4 is located below the smart display screen 3, and the camera 4 and the weighing seat 6 are electrically connected to the smart display screen 3. The four corners of the lower part of the base 1 are connected to the buffer sheet 5 by the first spring 501, and the buffer sheet 5 completely covers the corresponding corners of the base 1.

[0031] First, the staff turns on the weighing seat 6, inserts the fingers into the first groove 111 to grab the cabinet door 11, and then rotates the cabinet door 11 backward to open the placement cabinet 10. When the cabinet door 11 rotates, it drives the fan gear 12 to rotate and mesh with the rack 14, so that the rack 14 drives the tray 13 to move backward to the outside of the placement cabinet 10, and then inserts the fingers into the second groove 131 to grab the tray 13, pulls it out of the placement cabinet 10, and then puts the items to be delivered into the tray 13. After the placement is completed, the weighing seat 6 runs to weigh the weight of the placement cabinet 10 after peeling, and the weighed value is displayed on the smart display screen 3 for the staff to view, so that the staff can know the specific weight of the items, and then add or reduce items according to the carrying capacity of the delivery robot. In the process of the delivery robot delivering items, when the base 1 collides with an external wall or obstacle, the buffer sheet 5 is pre-extruded and moves inward to compress the first spring 501, thereby playing a buffering role and reducing the collision force between the base 1 and the external wall or obstacle.

[0032] Example 2: Based on Example 1, refer to Figure 2-Figure 7 As shown, it also includes a wedge-shaped block 7, a second spring 8 and a pull rod 9. The weighing seat 6 is slidably connected to the inside with wedge-shaped blocks 7 distributed on the left and right. At least two second springs 8 are connected between the wedge-shaped block 7 and the weighing seat 6. The two sides of the wedge-shaped blocks 7 that are away from each other are connected to the pull rod 9 by welding. The second spring 8 is sleeved on the outside of the pull rod 9. The left and right sides of the lower part of the storage cabinet 10 are provided with slots 101. The wedge-shaped block 7 is engaged with the corresponding slot 101, so that the storage cabinet 10 is reinforced on the weighing seat 6. By pulling the pull rod 9 outward, the wedge-shaped block 7 moves outward and disengages from the slot 101.

[0033] When it is necessary to replace a storage cabinet 10 of a different specification, the staff holds the pull rod 9 by hand to pull the wedge-shaped block 7 outward, and the second spring 8 is compressed, thereby disengaging the wedge-shaped block 7 from the slot 101, and then replaces the storage cabinet 10. After the replacement is completed, the pull rod 9 is released, and the second spring 8 returns to its original state, thereby moving the wedge-shaped block 7 inward to engage with the slot 101 to reinforce the replaced storage cabinet 10, thereby improving the stability of the storage cabinet 10.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
