Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-3 This utility model provides a technical solution: a container door curtain assembly, including a container body 1, two door bodies 2 installed on the surface of the container body 1, and a door curtain structure 3 provided on the inner wall of the container body 1. The door curtain structure 3 includes a servo motor 301, which is fixedly connected to the inner wall of the container body 1. A drive rod 302 is fixedly connected to the output end of the servo motor 301. A plurality of wire reels 303 are fixedly connected to the surface of the drive rod 302. Steel wire ropes 304 are wound and fixedly fixed on the surface of the wire reels 303. The plurality of steel wire ropes 304 are located away from the wire reels 303. A curtain body 306 is fixedly connected to one end, and a fixing rod 305 is fixedly connected to the inner wall of the container 1. The curtain body 306 is attached to the surface of the fixing rod 305, and a curtain structure 3 is set up. The curtain is raised and lowered by a combination of servo motor 301, drive rod 302, coil 303 and wire rope 304. This effectively improves the overall strength and sealing of the curtain. In addition, the curtain body 306 does not require additional space to accommodate the folding part during the raising and lowering process, which is more suitable for containers with limited space and improves the utilization rate of the container's internal space.

[0030] Reference Figure 4 - Figure 6As shown in this embodiment: several bolts 308 penetrate the surface of the curtain body 306. Two counterweights 307 are fitted at one end of the curtain body 306. The counterweights 307 are fixedly connected to the surface of the curtain body 306 using bolts 308. The counterweights 307 on the curtain body 306 will fit against the bottom surface inside the container 1, and the counterweights 307 serve to prevent the curtain body 306 from being lifted by the wind. A rectangular hole 309 is opened on the surface of the curtain body 306. Magnetic strips A310 and B311 are fixedly connected to both sides of the inner wall of the rectangular hole 309, respectively. Magnetic strips A310 and B311 are magnetically attracted to each other. By opening a rectangular hole 309 on the surface of the curtain body 306, the need to lift the entire curtain body 306 is avoided when personnel enter the container. Magnetic strips A310 and B311 facilitate sealing at the rectangular hole 309. An extension rod 312 is fixedly connected to one end of the counterweight 307 near the inner wall of the housing 1. Rectangular grooves 313 are provided on both sides of the inner wall of the housing 1. The extension rod 312 slides along the inner wall of the rectangular grooves 313. When the curtain body 306 is raised, the counterweight 307 drives the extension rod 312 to slide along the inner wall of the rectangular grooves 313. The rectangular grooves 313 restrict the movement path of the extension rod 312, thereby restricting the movement path of the counterweight 307. This prevents the counterweight 307 from swinging during the raising of the curtain body 306, which would increase the resistance to lifting. A cylinder 314 is fitted onto the arc surface of the fixing rod 305. During the raising and lowering of the curtain body 306, the cylinder 314 on the fixing rod 305 reduces the friction between the curtain body 306 and the fixing rod 305, making the raising and lowering of the curtain smoother. The arc surface of the drive rod 302 is fitted with several brackets 315, which are fixedly connected to the inner wall of the box 1. The brackets 315 support the drive rod 302, ensuring its stable rotation. A protective plate 316 is fixedly connected to the inner wall of the box 1. The protective plate 316 covers part of the curtain structure 3, protecting the components of the curtain structure 3 and preventing damage from collisions with goods.

[0031] Working principle: When the curtain body 306 is used to seal the container door, it covers the container opening. The counterweight strip 307 on the curtain body 306 adheres to the bottom surface inside the container body 1, preventing the curtain body 306 from being lifted by the wind. When it is necessary to enter the container, the curtain body 306 is pushed, and it unfolds through the rectangular hole 309 in the middle. The magnetic strips A310 and B311 inside the rectangular hole 309 disengage, facilitating entry for personnel. The curtain body 306 then returns to its original position due to inertia, at which point the magnetic strips A310 and B311 attract each other. The rectangular hole 309 on the surface of the curtain body 306 prevents the entire curtain body 306 from being lifted when entering the container. The magnetic strips A310 and B311 seal the rectangular hole 309. When it is necessary to open the container curtain body 306... 06 When loading and unloading goods, the servo motor 301 is started to reverse, and the drive rod 302 drives the reel 303 to rotate in the opposite direction. The reel 303 releases the wire rope 304, and the curtain body 306 moves upward along the fixed rod 305 under its own weight and the action of the wire rope 304 until it is fully retracted. During the raising and lowering of the curtain body 306, the cylinder 314 on the fixed rod 305 reduces the friction between the curtain body 306 and the fixed rod 305, making the raising and lowering of the curtain smoother. The bracket 315 provides support. Drive rod 302 to ensure stable rotation. Protective plate 316 protects the components of curtain structure 3 and prevents damage caused by collision with goods. When curtain body 306 is raised, counterweight 307 will drive extension rod 312 to slide along the inner wall of rectangular groove 313. Rectangular groove 313 restricts the movement path of extension rod 312, thereby restricting the movement path of counterweight 307. This avoids the counterweight 307 from swinging when curtain body 306 is raised, which would increase the lifting resistance.
