Description

Technical Field

[0001] The utility model relates to the technical field of frame structures, and particularly relates to a frame structure of a new type of curtain-sided semi-trailer. Background Technique

[0002] The curtain-sided semi-trailer, also known as a side curtain vehicle, demonstrates its advantages in multiple fields with its unique structure and functions. This vehicle type consists of a chassis, columns, crossbeams, and curtain cloth. The curtain cloth on both sides can be quickly opened, making it very convenient to load and unload goods. Therefore, it has a wide range of applications in multimodal transport, transportation of household appliances, transportation of beverages, etc.

[0003] During the use of the existing curtain-sided semi-trailer, when the curtain cloth is folded, the sliding support frame at one end provides power traction to fold the curtain cloth. However, the middle fixing frame only slides along with the support frame. After the curtain cloth is closed, the middle fixing frame cannot be fixed, resulting in the middle fixing frame sliding by itself during the driving of the curtain-sided semi-trailer. Over time, it is easy to cause damage to the curtain cloth, increasing the maintenance cost. In view of the above problems, the inventor proposes a frame structure of a new type of curtain-sided semi-trailer to solve the above problems. Content of the Utility Model

[0004] In order to solve the problem that after the curtain cloth is closed, the middle fixing frame cannot be fixed, resulting in the middle fixing frame sliding by itself during the driving of the curtain-sided semi-trailer and being prone to damage the curtain cloth over time; the purpose of the present utility model is to provide a frame structure of a new type of curtain-sided semi-trailer.

[0005] To solve the above technical problems, the present utility model adopts the following technical solutions: A frame structure of a new type of curtain-sided semi-trailer, including a carriage body.

A threaded portion is fixedly arranged on the outer surface of the sleeve. A threaded ring is threadedly sleeved on the outer surface of the threaded portion. A rubber pad is fixedly arranged on one side of the threaded ring. First, when the electric slide rail is turned on, the electric slider can be controlled to slide in the electric slide rail, so that the support frame drives the curtain body and a plurality of fixed frames to move, opening or closing the curtain body. After the curtain body is closed, the fixed frame drives the fixing plate to coincide with the limiting block. By pressing the movable rod, the fixed ring slides in the movable groove and compresses the spring. At the same time, the movable rod abuts against the L-shaped plate to rotate on the outer surface of the fixed shaft and is stored in the storage groove. Then the sleeve is inserted into the fixing plate and the limiting block. Then the movable rod is released, so that the spring resets. Then the L-shaped plate slides in the limiting groove. Then the threaded ring is rotated on the outer surface of the threaded portion so that the threaded ring fits against one side of the fixing plate, prompting the L-shaped plate to be stuck in the limiting groove, thereby being able to fix the fixed frame, avoiding the fixed frame from moving during driving and causing the curtain body to be torn, reducing the maintenance cost.

[0006] Preferably, a movable rod is slidably inserted into the sleeve. One end of the movable rod is fixedly provided with a connecting rod.

[0018] Embodiment: As Figures 1-5As shown in the figure, the present utility model provides a frame structure of a new type of curtained box semi-trailer, including a carriage body 1. A support frame 12 and a fixed frame 13 are slidably arranged in the carriage body 1. A curtain body 14 is fixedly arranged between the support frame 12 and the fixed frame 13. One side of the fixed frame 13 is fixedly provided with a fixing plate 2. A sleeve 21 is movably inserted into the fixing plate 2. A limiting block 15 is fixedly arranged in the carriage body 1. The sleeve 21 is movably inserted into the limiting block 15. A receiving groove 211 is opened in the sleeve 21. A fixed shaft 26 is fixedly arranged in the receiving groove 211. An L-shaped plate 27 is rotatably sleeved on the outer surface of the fixed shaft 26. A limiting groove 151 is opened in the limiting block 15. The L-shaped plate 27 is movably arranged in the limiting groove 151. A threaded portion 22 is fixedly arranged on the outer surface of the sleeve 21. A threaded ring 23 is threadedly sleeved on the outer surface of the threaded portion 22. A rubber pad 24 is fixedly arranged on one side of the threaded ring 23. The number of the fixed frames 13 is set to three groups. After the curtain body 14 is closed, the fixed frame 13 drives the fixing plate 2 to coincide with the limiting block 15. Then the sleeve 21 is inserted into the fixing plate 2 and the limiting block 15. Then the L-shaped plate 27 slides in the limiting groove 151. Then the threaded ring 23 is rotated on the outer surface of the threaded portion 22 to make the threaded ring 23 fit against one side of the fixing plate 2, so that the L-shaped plate 27 is stuck in the limiting groove 151, thereby being able to fix the fixed frame 13, avoiding the fixed frame 13 from moving during driving, causing the curtain body 14 to be torn, and reducing the maintenance cost.

[0019] A movable rod 25 is slidably inserted into the sleeve 21. One end of the movable rod 25 is fixedly provided with a connecting rod 28. One end of the connecting rod 28 is fixedly provided with a fixing ring 29. The fixing ring 29 is slidably arranged in the sleeve 21. An activity groove 212 is opened in the sleeve 21. The fixing ring 29 is slidably arranged in the activity groove 212. A spring 292 is fixedly connected between the activity groove 212 and the fixing ring 29. One side of the fixing ring 29 is fixedly provided with a plug rod 291. The plug rod 291 is slidably inserted into the sleeve 21. A slot 213 is opened in the sleeve 21. The plug rod 291 is movably inserted into the slot 213.

[0020] By adopting the above technical solution, by pressing the movable rod 25, the fixing ring 29 slides in the activity groove 212 and compresses the spring 292. At the same time, the movable rod 25 abuts against the L-shaped plate 27 to rotate on the outer surface of the fixed shaft 26 and is received in the receiving groove 211.

[0021] An electric slide rail 11 is fixedly arranged in the carriage body 1. Electric sliders are fixedly arranged at both ends of the support frame 12. The electric sliders are slidably arranged in the electric slide rail 11.

[0022] By adopting the above technical solution, two sets of electric slide rails 11 are provided and are synchronously opened. When the electric slide rails 11 are opened, the electric sliders can be controlled to slide within the electric slide rails 11, so that the support frame 12 drives the curtain body 14 and multiple fixing frames 13 to move, thereby opening or closing the curtain body 14.

[0023] Working principle: First, when the electric slide rail 11 is opened, the electric slider can be controlled to slide within the electric slide rail 11, so that the support frame 12 drives the curtain body 14 and multiple fixing frames 13 to move, thereby opening or closing the curtain body 14. After the curtain body 14 is closed, the fixing frame 13 drives the fixing plate 2 to coincide with the limiting block 15. By pressing the movable rod 25, the fixing ring 29 slides within the movable slot 212 and compresses the spring 292. At the same time, the movable rod 25 abuts against the L-shaped plate 27 to rotate on the outer surface of the fixed shaft 26 and is received within the receiving slot 211. Then, the sleeve 21 is inserted into the fixing plate 2 and the limiting block 15. Then, the movable rod 25 is released, so that the spring 292 resets. Then, the L-shaped plate 27 slides within the limiting slot 151. Then, the threaded ring 23 is rotated on the outer surface of the threaded portion 22, so that the threaded ring 23 fits against one side of the fixing plate 2, prompting the L-shaped plate 27 to be stuck within the limiting slot 151, thereby enabling the fixing frame 13 to be fixed, such that during driving, the fixing frame 13 is prevented from moving, causing the curtain body 14 to be torn, and reducing the maintenance cost.

[0024] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model.
