Description

Technical Field

[0001] This utility model relates to the field of container manufacturing technology, and in particular to a container door end reinforcement structure. Background Technology

[0002] As a core carrier of logistics transportation, the door structure of a container must withstand vibration, impact, and cargo compression loads during long-term transport. Existing container door structures mostly use a single frame structure, with the lintel, sill, and uprights only fixed by simple welding. This presents the following problems: insufficient overall rigidity of the door frame, leading to lintel sagging and upright bending after long-term use, making door closure difficult; the door lock installation area is a stress concentration point, and existing structures lack targeted reinforcement, making cracks easily form around the lock hole, affecting locking reliability; due to structural deformation, the sealing mating surface between the door and the container door is prone to uneven compression of the sealing strip, leading to rainwater leakage. Therefore, a reinforced container door structure is needed. Utility Model Content

A guide block 6 is arranged on the front side of the container door body 2 located on the right side, corresponding to the position of each mounting block 3. The container door body 2 and the guide block 6 are fixedly connected. Two sliding grooves are opened through each guide block 6. A connecting rod 7 is slidably arranged on the side of the two sliding grooves that are far apart from each other to facilitate the guiding and limiting of the operation of the connecting rod 7. A limit block 20 is arranged on the front side of the container door body 2 located on the right side of each connecting rod 7. The container door body 2 and the limit block 20 are fixedly connected. Each connecting rod 7 has a T-block 21 on its right side, with the right side of the connecting rod 7 fixedly connected to the left side of the T-block 21. A T-slot is provided on the left side of the limiting block 20 at the position of each T-block 21, with the T-block 21 slidingly connected to the T-slot for guiding and limiting the connecting rod 7. Each connecting rod 7 has a pin 8 on its left side, with the left side of the connecting rod 7 fixedly connected to the right side of the pin 8. Each pin 8 engages with a corresponding arc-shaped slot 5, ensuring a stable connection between the left and right container doors 2. Each connecting rod 7 has an L-shaped wrench 9 on one side close to each other. The connecting rod 7 and the L-shaped wrench 9 are fixedly connected to each other, which makes it easy to remove the pin 8 from the inside of the arc-shaped slot 5. A telescopic rod 10 is provided between the two connecting rods 7. The telescopic rod 10 is fixed between the corresponding two connecting rods 7. A spring 11 is sleeved on the outer ring of the telescopic rod 10. The spring 11 can be guided and limited by the telescopic rod 10. A reinforcing rod 12 is provided on the front side of each container door 2. The front side of the container door 2 is fixedly connected to the rear side of the reinforcing rod 12. Each reinforcing rod 12 has a knob 13 rotatably mounted on its top and bottom surfaces. Both the top and bottom surfaces of the reinforcing rod 12 have L-shaped annular grooves. Each knob 13 has an L-shaped ring 22 near the reinforcing rod 12. The knob 13 is fixedly connected to the L-shaped ring 22, while the L-shaped ring 22 is rotatably connected to its corresponding L-shaped annular groove. This allows for limiting the movement of the L-shaped ring 22, thereby limiting the movement of the knob 13. Each knob 13 has a threaded rod 14 threadedly connected to its inner ring. Each reinforcing rod 12... Rectangular grooves are provided inside the top and bottom of rod 12. A rectangular block 23 is provided at one end of each threaded rod 14 near the reinforcing rod 12. The threaded rod 14 is fixedly connected to the rectangular block 23, and the rectangular block 23 is slidably connected to the rectangular groove. This facilitates the guiding and limiting of the threaded rod 14, allowing it to run in a straight line. A positioning block 15 is provided on the front side of the container door frame 1 corresponding to the top and bottom of each reinforcing rod 12. The container door frame 1 is fixedly connected to the positioning block 15. Each threaded rod 14 is slidably connected to its corresponding positioning block 15, facilitating reinforcement of the container door 2. Each container door 2 has a reinforcing rod 16 on its front side, which is fixedly connected to the front of the container door 2. A knob 17 is rotatably mounted on the side of each reinforcing rod 16 that is furthest from each other. An L-shaped annular groove is formed on the side of each reinforcing rod 16 that is furthest from each other, and an L-shaped ring is formed on the side of each knob 17 that is close to each other. 24. Knob 27 is fixedly connected to L-shaped ring 24. L-shaped ring 24 is rotatably connected to the corresponding L-shaped ring groove 2, which facilitates limiting the L-shaped ring 24 and thus limiting the knob 27. The inner ring of each knob 27 is threadedly connected to a threaded rod 28. Each reinforcing rod 26 has a rectangular groove 2 inside. A rectangular block 25 is provided at the end of each of the two threaded rods 28 that are close to each other. The threaded rod 28 and the rectangular block 25 are fixedly connected. Rectangular block 25 is slidably connected to rectangular groove 2, which facilitates the guiding and limiting of threaded rod 18, ensuring that threaded rod 18 always moves in a straight line. Positioning block 19 is provided on the front side of container door frame 1 at the position of each reinforcing rod 16. Container door frame 1 is fixedly connected to positioning block 19, and each threaded rod 18 is slidably connected to the corresponding positioning block 19, which facilitates the reinforcement of container door 2.

[0019] In this embodiment, when using this device, if longitudinal reinforcement of the container door 2 is required, knob 13 can be rotated. Rotating knob 13 will drive threaded rod 14 to move up and down, thereby installing threaded rod 14 into the corresponding positioning block 15. If lateral reinforcement of the container door 2 is required, knob 2 can be rotated. Rotating knob 2 will drive threaded rod 18 to move, thereby installing threaded rod 18 into the corresponding positioning block 19. When locking the two container doors 2, simply close the left container door 2 first, then press the right container door 2 against the left container door 2, so that pin 8 is installed into the corresponding arc-shaped slot 5 through the inclined surface of trapezoidal groove 4, thereby ensuring the stability of the installation of the two container doors 2. When opening, simply move the two L-shaped wrenches 9 to the side that is closer to each other to bring the two pins 8 closer together, thereby moving the pins 8 out of the arc-shaped slot 5, thus completing the opening and closing.

[0020] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
