A heavy duty packaging box for easy lifting

Abstract

This utility model belongs to the technical field of heavy-duty packaging boxes and discloses a heavy-duty packaging box that is easy to lift. It includes a box body, with a base plate fixedly connected to the bottom of the box body. Round rods are fixedly installed on both the left and right sides of the inner surface of the base plate. This utility model incorporates a movable plate, a double-threaded rod, a hinged rod, and a U-shaped ring. The U-shaped ring design allows operators to connect the lifting ring to the U-shaped ring for lifting the entire box, facilitating operation. When the position of the U-shaped ring needs adjustment, rotating the handle causes the double-threaded rod to move two movable blocks in opposite directions, which in turn causes the hinged rod to move two movable plates in opposite directions, thus adjusting the position of the U-shaped ring. This allows operators to adjust the position of the U-shaped ring according to the actual lifting situation, optimizing the lifting angle and making the lifting process more stable.

Description

Technical Field

[0001] This utility model belongs to the field of heavy-duty packaging box technology, specifically a heavy-duty packaging box that is easy to lift. Background Technology

[0002] Heavy-duty crates are robust packaging containers designed specifically for carrying and transporting heavy, large, or valuable items. They are typically made of high-strength materials such as wood, metal, or engineering plastics, and possess excellent resistance to pressure, impact, and moisture, effectively protecting the contents from damage caused by the external environment and during transportation.

[0003] Existing heavy-duty packaging boxes often require hoisting during transport. The common method for hoisting heavy-duty packaging boxes is to pass steel wire ropes through the bottom of the box, lifting it up. While this method is effective, it is cumbersome, requiring the wire ropes to pass through the bottom of the box, which reduces hoisting efficiency. Furthermore, the wire ropes can shift relative to the box, leading to instability during hoisting. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the above problems. This utility model provides a heavy-duty packaging box that is easy to lift, and has the advantage of being easy to lift.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty packaging box that is easy to hoist, comprising a box body, a bottom plate fixedly connected to the bottom of the box body, round rods fixedly installed on both the left and right sides of the inner surface of the bottom plate, mounting blocks fixedly sleeved on the inner side of the outer surface of the round rods, the bottom of the mounting blocks fixedly connected to the inner surface of the bottom plate, a movable plate movably sleeved on the outer surface of the round rods, the outer surface of the movable plate movably connected to the inner surface of the bottom plate, fixing blocks fixedly installed on both the front and rear sides of the inside of the bottom plate, two fixing blocks, a double threaded rod movably sleeved between the two fixing blocks, a movable block threadedly sleeved on both the front and rear sides of the outer surface of the double threaded rod, the top and bottom of the movable block movably connected to the inner surface of the bottom plate, hinge rods hinged to the inside of both the left and right sides of the movable block, the other end of the hinge rods hinged to the inner side of the movable plate, two movable plates, and U-shaped rings fixedly connected to the front and rear sides of the top of the two movable plates.

[0006] As a preferred embodiment of this utility model, a rotating plate is fixedly connected to the front end of the double threaded rod, and a handle is movably sleeved inside the bottom end of the rotating plate.

[0020] 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.

[0021] like Figures 1 to 5 As shown, this utility model provides a heavy-duty packaging box that is easy to lift, including a box body 1. A bottom plate 2 is fixedly connected to the bottom of the box body 1. Round rods 3 are fixedly installed on both the left and right sides of the inner surface of the bottom plate 2. Mounting blocks 4 are fixedly sleeved on the inner side of the outer surface of the round rods 3. The bottom of the mounting blocks 4 is fixedly connected to the inner surface of the bottom plate 2. A movable plate 5 is movably sleeved on the outer surface of the round rods 3. The outer surface of the movable plate 5 is movably connected to the inner surface of the bottom plate 2. Fixing blocks 6 are fixedly installed on both the front and rear sides of the bottom plate 2. There are two fixing blocks 6. A double threaded rod 7 is movably sleeved between the two fixing blocks 6. Movable blocks 8 are threadedly sleeved on both the front and rear sides of the outer surface of the double threaded rod 7. The top and bottom of the movable blocks 8 are movably connected to the inner surface of the bottom plate 2. The left and right sides of the movable blocks 8 are... The internal components are all hinged with hinge rods 9, the other end of which is hinged to the inner side of the movable plate 5. There are two movable plates 5, and U-shaped rings 10 are fixedly connected to the front and rear sides of the top of the two movable plates 5. The operator can connect the lifting rings to the U-shaped rings 10, which facilitates the hoisting of the entire box 1 and eliminates the step of passing the steel wire rope connected to the lifting ring through the bottom of the box 1. When the operator needs to adjust the position of the U-shaped rings 10, the double threaded rod 7 can be rotated. Since the threads on the front and rear sides of the outer surface of the double threaded rod 7 are opposite, the double threaded rod 7 can drive the two movable blocks 8 to move in opposite directions, thereby driving the two movable plates 5 to move in opposite directions through the hinge rods 9, thus adjusting the position of the U-shaped rings 10.

[0022] The front end of the double threaded rod 7 is fixedly connected to a rotating plate 11, and a handle 12 is movably sleeved inside the bottom end of the rotating plate 11. The operator can rotate the handle 12 to drive the rotating plate 11 to rotate, which in turn drives the double threaded rod 7 to rotate, thereby driving the two moving blocks 8 to move.

[0023] The top of the box 1 is movably connected to a cover plate 13, and the bottom of the base plate 2 is fixedly connected to a support block 14. There are three support blocks 14, and the three support blocks 14 are of the same height. By setting the support blocks 14, the support blocks 14 can support the base plate 2, thereby facilitating the forklift to transport the box 1 as a whole.

[0024] Mounting plates 15 are fixedly installed on the left and right sides of the top of the front and back of the housing 1, and crossbars 16 are fixedly connected between the mounting plates 15; by setting the mounting plates 15, the mounting plates 15 can support and fix the crossbars 16.

[0025] The crossbar 16 has sliders 17 movably sleeved on both sides of its outer surface. The sliders 17 have a first bolt 18 threaded inside. The operator can push the sliders 17 to move along the outer surface of the crossbar 16. When it is necessary to fix the position of the sliders 17, the first bolt 18 can be rotated so that the inner end of the first bolt 18 abuts against the outer surface of the crossbar 16, thereby fixing the position of the sliders 17.

[0026] The outer surface of the slider 17 is fixedly mounted with a support frame 19, and the support frame 19 is threaded with a second bolt 20. The operator can rotate the second bolt 20 to make the second bolt 20 move forward or backward inside the support frame 19.

[0027] The inner end of the second bolt 20 is movably sleeved with a circular sleeve 21, and the rear end of the circular sleeve 21 is fixedly connected with a clamping plate 22. The operator can rotate the clamping plate 22 to make the circular sleeve 21 rotate on the outer surface of the second bolt 20, thereby adjusting the tilt angle of the clamping plate 22 so that the tilt angle of the clamping plate 22 can match the tilt angle of the wire rope.

[0028] Working principle and usage process of this utility model:

[0029] When the operator needs to lift the box 1, he can first rotate the handle 12 to make the rotating plate 11 drive the double threaded rod 7 to rotate, so that the double threaded rod 7 can drive the two moving blocks 8 to move in opposite directions. Then, through the hinge rod 9, the moving plate 5 moves in opposite directions along the outer surface of the round rod 3, thereby adjusting the position of the U-shaped ring 10. This allows the operator to adjust the position of the U-shaped ring 10 according to the actual lifting situation, thereby optimizing the lifting angle and making the lifting process more stable. After the position of the U-shaped ring 10 is adjusted, the lifting ring can be connected to the U-shaped ring 10.

[0030] After the lifting ring is connected to the U-shaped ring 10, as the wire rope taut, the sliding block 17 can be moved to move the clamping plate 22 to the appropriate position. Then, by rotating the first bolt 18, the inner end of the first bolt 18 abuts against the crossbar 16, thereby fixing the position of the sliding block 17. Then, by rotating the clamping plate 22, the clamping plate 22 drives the sleeve 21 to rotate on the outer surface of the second bolt 20, thereby adjusting the tilt angle of the clamping plate 22 so that the tilt angle of the clamping plate 22 matches the tilt angle of the wire rope. Then, by rotating the second bolt 20, the second bolt 20 drives the clamping plate 22 closer to the wire rope, so that the clamping plate 22 presses the wire rope against the front of the sliding block 17, thereby fixing the position of the wire rope and preventing the wire rope from slipping during the hoisting process, which would cause the entire box 1 to shake, thus improving the stability of the hoisting.
