Description

Technical Field

[0001] This utility model relates to the field of container locking bar technology, and in particular to an impact-resistant container locking bar. Background Technology

[0002] Containers have become a standard international transport tool for multimodal transport. Container locking devices are auxiliary equipment installed on the container doors to allow for opening and closing and to lock the doors to the container frame. Figure 1 As shown, a common container locking mechanism involves fixing the locking bar to the container door panel via two large upper and lower brackets and a small middle bracket. The locking bar itself is made of steel tubing, with lock heads welded to its upper and lower ends. A limiting sleeve is fixed to the locking bar to prevent axial movement within the large brackets, and a handle is provided for rotating and locking the locking bar. When closing and locking the door, the handle engages the lock heads with the lock seat on the container door frame, closing the door and securing the handle to the door panel to prevent the locking bar from rotating or unlocking. However, in actual use, if the cargo inside the container is heavy bulk cargo, and the proportion of bulk cargo is relatively large, when driving on slopes or bumpy roads, the bulk cargo inside the container will move due to inertia and violently impact and press against the container door. As the locking rod in the joint area of ​​the container door panel and door frame will be subjected to concentrated force, it will cause deformation of the locking rod in the joint area of ​​the container door panel and door frame. To solve the above problems, an impact-resistant container locking rod with good bending strength is provided. Utility Model Content

[0003] In order to solve the problems mentioned in the background art, the present invention provides an anti-impact container locking bar.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An impact-resistant container locking bar includes a locking bar body, with large brackets provided near both ends of the locking bar body, anti-bending components provided near both ends of the locking bar body and located outside the large brackets, and lock heads provided at both ends of the locking bar body;

[0006] The bending-resistant component includes a lower arc-shaped reinforcing plate and an upper arc-shaped reinforcing plate. Both the lower arc-shaped reinforcing plate and the upper arc-shaped reinforcing plate are in contact with the locking rod body. Both the lower arc-shaped reinforcing plate and the upper arc-shaped reinforcing plate are provided with fixing ears, and fixing bolts are provided on the fixing ears.

[0007] Preferably, a fixing seat is fixedly connected to the middle part of the locking rod, and a handle is provided on the fixing seat.

[0008] Preferably, the circumferential sidewalls of the locking rod are provided with a first limiting ring and a second limiting ring on both sides of the large bracket.

[0009] Preferably, small brackets are provided at both ends of the locking rod, and the small brackets are fixedly connected to the container door.

[0010] Preferably, the lock head is provided with a connecting rod, the connecting rod is inserted into the lock rod body, and the end of the connecting rod extends to the second limiting ring.

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

[0012] 1. Attach the lower and upper arc-shaped reinforcing plates to the side wall of the locking rod body, adjust their positions so that the joint area between the container door panel and the door frame is aligned with the middle of the lower and upper arc-shaped reinforcing plates, and fix them with fixing bolts. This strengthens the locking rod body near the lock head and can prevent the locking rod from bending due to stress impact on the door panel and door frame during cargo transportation and loading and unloading.

[0013] 2. The connecting rod is inserted into the lock rod body, and the end of the connecting rod extends to the second limiting ring. With this design, the position of the lock rod body near the lock head, that is, the joint area between the container door panel and the door frame, is no longer a hollow steel pipe. Compared with the existing lock rod, the connecting handle extends to the first limiting ring, which can greatly improve the bending strength at this point.

[0014] In summary, this utility model overcomes the shortcomings of the prior art and has a reasonable design. By setting an anti-bending component at the position where the locking rod bears the greatest shear force, it can greatly enhance the bending strength of the locking rod and has high social use value and application prospects.
