Description

Technical Field

[0001] This utility model relates to the field of trailer accessories, specifically a container trailer fixing device. Background Technology

[0002] Container trailers play a crucial role in the global logistics system as an important carrier of goods. The performance of their securing devices directly affects the safety and stability of cargo transportation.

[0003] Conventional container securing devices typically employ simple mechanical locking mechanisms, relying solely on the rotation of a handle for locking and unlocking. However, in actual transportation, the frequent bumps and undulations of the road and the severe vibrations generated by the trailer can easily cause the handle to rotate unexpectedly. Once the container door opens, the cargo faces a significant risk of falling out, potentially causing severe damage and even triggering a serious traffic accident, endangering road safety and the lives and property of those nearby. Utility Model Content

[0004] The purpose of this utility model is to provide a container trailer fixing device to solve the problem of insufficient structural reliability of traditional container fixing devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a container trailer fixing device, including a lock box, a lock body and a lock handle, wherein a U-shaped rod is movably installed on the side wall of the lock box through a pair of pivots, and an elastic member is connected between the U-shaped rod and the lock box, and the lock handle is provided with a pair of slots for accommodating the U-shaped rod so that the U-shaped rod abuts against the lock handle to limit and protect it.

[0006] Preferably, the rotating shaft is rotatably mounted on the side wall of the lock box, and the side wall of the rotating shaft is provided with a round hole for the U-shaped rod to pass through. Both ends of the U-shaped rod pass through the round hole of the rotating shaft and are threaded with nuts.

[0007] Preferably, a positioning clip is fixedly sleeved on the side wall of the rotating shaft, and the elastic member is a torsion spring sleeved on the rotating shaft, with both ends of the torsion spring contacting the positioning clip and the lock box, respectively.

[0008] Preferably, the lock box has U-shaped grooves on both sides for accommodating the torsion spring.

[0009] Preferably, the front side of the lock box is integrally formed with a protrusion, and the protrusion is provided with a groove for accommodating the U-shaped rod.

[0010] Preferably, the corners of the lock box are all smoothly transitioned by rounding.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model installs a limiting assembly on the lock box, consisting of a rotating shaft, a U-shaped rod, a torsion spring, and a positioning card. Under the elastic force of the torsion spring, the U-shaped rod in the limiting assembly tightly abuts against the lock handle, forming a strong resistance. This effectively prevents the lock handle from rotating due to external forces such as vibration and collision, ensuring that the fixing device is always in a locked state, protecting the safety of goods inside the container throughout the transportation process, and reducing the probability of transportation accidents.

[0018] 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.

[0019] Please see Figures 1-4This utility model provides a technical solution: a container trailer fixing device, including a lock box 1, a lock body 2, and a lock handle 3. The lock box 1 and lock body 2 are existing technologies, and their principles will not be elaborated here. A U-shaped rod 5 is movably mounted on the side wall of the lock box 1 via a pair of rotating shafts 4. The rotating shafts 4 are rotatably mounted on the side wall of the lock box 1. The side wall of the rotating shafts 4 has a circular hole through which the U-shaped rod 5 passes. Both ends of the U-shaped rod 5 pass through the circular hole of the rotating shaft 4 and are threaded with nuts. An elastic component connects the U-shaped rod 5 and the lock box 1. A positioning clip 7 is fixedly sleeved on the side wall of the rotating shaft 4. The end of the positioning clip 7 has a limiting groove. The elastic component is a torsion spring 6 sleeved on the rotating shaft 4. Both ends of the torsion spring 6 contact the limiting groove of the positioning clip 7 and the lock box 1, respectively. U-shaped grooves for accommodating the torsion spring 6 are provided on both sides of the lock box 1. The corners of the lock box 1 are smoothly transitioned by rounding. The advantage of this design is to avoid scratching the skin at the corners. The lock handle 3 is provided with a pair of slots 8 for accommodating the U-shaped rod 5, so that the U-shaped rod 5 abuts against the lock handle 3 to limit its movement. The front side of the lock box 1 is integrally formed with a protrusion, and the protrusion is provided with a groove 9 for accommodating the U-shaped rod 5. When it is necessary to release the restriction of this fixing device on the container, the U-shaped rod 5 is rotated upward to its groove 9 position, and then the U-shaped rod 5 is pushed towards the rotating shaft 4, so that the U-shaped rod 5 and the groove 9 are engaged and limited. At this time, the lock handle 3 is rotated in conjunction with the lock body 2 to release the restriction on the container. This application installs a limiting component on the lock box 1, which is composed of a rotating shaft 4, a U-shaped rod 5, a torsion spring 6 and a positioning card 7. Under the elastic force of the torsion spring 6, the U-shaped rod 5 in the limiting component is tightly abutted against the lock handle 3, forming a strong resistance, which effectively prevents the lock handle 3 from rotating due to external forces such as vibration and collision, ensuring that the fixing device is always in a locked state, ensuring the safety of the goods in the container throughout the transportation process, and reducing the probability of transportation accidents.
