Description

Technical Field

[0001] This utility model relates to the field of metal pallet box technology, specifically to a metal pallet box for logistics. Background Technology

[0002] Metal pallet boxes for logistics, also known as metal mesh boxes or mesh pallet boxes, are a modern type of packaging for warehousing and logistics transportation. They are widely used in industrial production, heavy machinery, food, pharmaceuticals, and many other fields. Made primarily of iron, steel, stainless steel, and other metal materials, metal pallet boxes have a sturdy structure that effectively protects the items stored inside. They have a strong load-bearing capacity and are suitable for storing and transporting heavy objects, castings, forgings, etc. They are acid and alkali resistant, durable, oil-resistant, non-toxic, and odorless, making them suitable for food storage as well. Compared to wooden or plastic pallets, metal pallet boxes have a longer service life and lower maintenance costs.

[0003] In existing technologies, metal pallet boxes are used in logistics transportation to load and transport goods. Most metal pallet boxes have fixed storage space. However, in practical applications, if there are many goods, one metal pallet box may not be enough to hold them all, leaving a small amount of goods. Using another metal pallet box would increase the area occupied and the number of times forklifts would handle the goods. Furthermore, most metal pallet boxes do not have any limiting components for the goods. During transportation, if the road is bumpy, the goods may collide with each other.

[0004] Therefore, a metal pallet box for logistics is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a metal pallet box for logistics in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A metal pallet box for logistics includes a base plate, a fixing rod at the bottom of the base plate, a support column at the top of the base plate, a fixing plate at the top of the support column, two fixing boxes at the top of the fixing plates, a clamping mechanism for clamping and limiting goods on the fixing plates, an expansion mechanism for expanding the storage space of goods on the two fixing boxes, and the expansion mechanism is set on the clamping mechanism. The expansion mechanism is provided with mounting holes, and the fixing rod is slidably installed on the inner wall of the mounting hole.

[0008] Furthermore, the clamping mechanism includes two fixed frames, which are symmetrically fixedly installed at the bottom of the fixed plate. A bidirectional lead screw is rotatably installed inside the left fixed frame, and a cylinder is fixedly installed inside the right fixed frame. Two movable boxes are threadedly installed on the outer wall of the bidirectional lead screw, and the movable boxes are slidably installed on the outer wall of the cylinder. The movable boxes are slidably installed on the fixed plate. The front end of the bidirectional lead screw extends outside the fixed frame, and a handle is fixedly installed on the surface of the fixed frame at the extended end.

[0009] Furthermore, the expansion mechanism includes two mounting frames, which are fixedly mounted on the surface of the fixed box plate. A double-acting lead screw is rotatably mounted inside each of the two mounting frames. Two sliding rods are threaded onto the outer walls of each of the two double-acting lead screws, and the sliding rods are slidably mounted on the inner walls of the mounting frames.

[0010] Furthermore, each of the four sliding rods is rotatably mounted with a double ring rod, and each of the two fixed box plates is slidably mounted with an expansion box plate, with mounting holes penetrating the expansion box plate. Each of the two expansion box plates is mounted with a connector, and the double ring rod is rotatably mounted on the connector.

[0011] Furthermore, an extension box second is slidably mounted on both of the movable box plates, and the extension box second is slidably mounted on the extension box first.

[0012] Furthermore, the front ends of both bidirectional lead screws extend outside the mounting frame, and synchronous pulleys are fixedly installed on the surfaces of both extended ends of the bidirectional lead screws. Synchronous belts are meshed on the outer walls of the two synchronous pulleys, and a handle is fixedly installed on the surface of one of the synchronous pulleys.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the arrangement of movable boxes, expansion boxes one, and expansion boxes two, etc., allows for easy operation. Turning handle two rotates the connected synchronous pulley, causing the two synchronous pulleys to rotate synchronously. This, in conjunction with the synchronous belt, causes the two double-acting screws two to rotate, resulting in four sliding rods moving closer together in pairs. This, in turn, causes four double-ring rods to rotate on the four sliding rods and two connecting parts, creating an angle change. This causes expansion boxes one to move upwards, and expansion boxes two to move accordingly, expanding the storage space and increasing the amount of goods that can be stored. Turning handle one rotates the double-acting screw one, causing the two movable boxes to move closer together, and expansion boxes two to move accordingly, clamping and limiting the goods to prevent collisions. This design facilitates easy clamping and limiting of goods, prevents collisions, and allows for easy expansion of storage space. It is simple to operate and highly practical.

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1 , Figure 3 As shown, a metal pallet box for logistics includes a base plate 1, a fixing rod 7 at the bottom of the base plate 1, a support column 2 at the top of the base plate 1, a fixing plate 3 at the top of the support column 2, and two fixing boxes 4 at the top of the fixing plate 3. The fixing plate 3 is equipped with a clamping mechanism 5 for clamping and limiting the position of goods, and the two fixing boxes 4 are equipped with an expansion mechanism 6 for expanding the storage space. The expansion mechanism 6 is mounted on the clamping mechanism 5 and has mounting holes 8. The fixing rod 7 is slidably mounted on the inner wall of the mounting holes 8. In this embodiment, during use, the storage space can be expanded through the expansion mechanism 6, increasing the number of goods that can be stored. The clamping mechanism 5 can clamp and limit the position of goods, preventing collisions between goods during transportation. The fixing rod 7 and the mounting holes 8 can be used to position multiple pallet boxes when stacked, thus facilitating the clamping and limiting of goods, preventing collisions between goods, and easily expanding the storage space. The operation is simple and highly practical.

[0025] like Figure 1-3 As shown, the clamping mechanism 5 includes two fixed frames 501, which are symmetrically fixedly installed at the bottom of the fixed plate 3. A bidirectional lead screw 502 is rotatably installed inside the left fixed frame 501, and a cylinder 503 is fixedly installed inside the right fixed frame 501. Two movable boxes 504 are threadedly installed on the outer wall of the bidirectional lead screw 502, and the movable boxes 504 are slidably installed on the outer wall of the cylinder 503. The movable boxes 504 are slidably installed on the fixed plate 3. The front end of the bidirectional lead screw 502 extends outside the fixed frame 501, and a handle 505 is fixedly installed on the surface of the extended end of the fixed frame 501. In this embodiment, by rotating the handle 505, the bidirectional lead screw 502 is rotated, causing the two movable boxes 504 to move closer to each other, clamping and limiting the goods, and preventing collisions between the goods.

[0026] like Figure 1 , Figure 3As shown, the expansion mechanism 6 includes two mounting frames 603, which are fixedly mounted on the surface of the fixed box plate 4. A double-acting lead screw 604 is rotatably mounted inside each of the two mounting frames 603. Two sliding rods 605 are threadedly mounted on the outer walls of the two double-acting lead screws 604, and the sliding rods 605 are slidably mounted on the inner walls of the mounting frames 603. In this embodiment, when the double-acting lead screw 604 rotates, it drives the two sliding rods 605 to move closer to each other or further away from each other, thereby adjusting the distance between the two sliding rods 605.

[0027] like Figure 3 As shown, double ring rods 606 are rotatably mounted on each of the four sliding rods 605, and expansion boxes 602 are slidably mounted on each of the two fixed boxes 4. Mounting holes 8 are provided through the expansion boxes 602. Connectors 607 are mounted on the surfaces of the two expansion boxes 602, and double ring rods 606 are rotatably mounted on the connectors 607. In this embodiment, when the four sliding rods 605 move closer to each other in pairs, they will drive the four double ring rods 606 to rotate on the four sliding rods 605 and the two connectors 607 respectively, resulting in an angle change, causing the two expansion boxes 602 to move upward, thereby adjusting the height of the expansion boxes 602.

[0028] like Figure 3 As shown, an extension box 601 is slidably mounted on each of the two movable box plates 504, and the extension box 601 is slidably mounted on the extension box 602. In this embodiment, when the extension box 602 moves upward, it causes the extension box 601 to move accordingly. When the two movable box plates 504 move closer to each other, the two extension box plates 601 move accordingly.

[0029] like Figure 3 As shown, the front ends of both bidirectional lead screws 604 extend outside the mounting frame 603. Synchronous pulleys 608 are fixedly mounted on the surfaces of both extended bidirectional lead screws 604. Synchronous belts 609 are meshed on the outer walls of the two synchronous pulleys 608. A handle 610 is fixedly mounted on the surface of one of the synchronous pulleys 608. In this embodiment, rotating the handle 610 drives the synchronous pulley 608 connected to it to rotate. With the cooperation of the synchronous belt 609, the two synchronous pulleys 608 rotate synchronously, and the two bidirectional lead screws 604 rotate accordingly.

[0030] In summary, during use, the storage space can be expanded through the expansion mechanism 6, increasing the number of goods that can be stored. The clamping mechanism 5 can clamp and limit the goods, preventing collisions during transport. The fixed rod 7 and mounting hole 8 allow for positioning when multiple pallets are stacked, facilitating clamping and limiting of goods to prevent collisions and expanding storage space. The operation is simple and highly practical. Rotating the handle 505 drives the bidirectional lead screw 502 to rotate, causing the two movable box plates 504 to move closer together, clamping and limiting the goods to prevent collisions. When the bidirectional lead screw 604 rotates, it drives the two sliding rods 605 to move closer or further apart, thus... The distance between the two slide rods 605 is adjusted. When the four slide rods 605 move closer to each other in pairs, they will drive the four double ring rods 606 to rotate on the four slide rods 605 and the two connecting parts 607 respectively, producing an angle change, causing the two expansion box plates 602 to move upward, thereby adjusting the height of the expansion box plates 602. When the expansion box plates 602 move upward, they drive the expansion box plates 601 to move accordingly. When the two movable box plates 504 move closer to each other, the two expansion box plates 601 move accordingly. Turning the handle 610 drives the synchronous pulley 608 connected to it to rotate. With the cooperation of the synchronous belt 609, the two synchronous pulleys 608 rotate synchronously, and the two double-acting screws 604 rotate accordingly.
