Description
Technical Field
[0001] This utility model relates to the field of container locking bar technology, and in particular to a folding multi-condition adaptive 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.
[0003] With the rapid development of global logistics and multimodal transport, the proportion of container transport in international trade continues to increase, placing higher demands on the security, adaptability, and operational efficiency of container locks. Existing locking bars are mostly fixed structures, making it difficult to adapt to different specifications and varying lock hole positions on containers. To address these issues, a length-adjustable, foldable, multi-condition adaptive locking bar is proposed. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a folding multi-condition adaptive locking bar.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A foldable multi-condition adaptive locking bar includes a locking bar body, with adjustable extension rods at both ends of the locking bar body, and a lock head detachably connected to the outer end of the extension rod;
[0007] The locking rod body has a fixing groove at both ends, and the fixing groove is slidably connected to one end of the extension rod. The locking rod body has a fixing block rotatably connected at both ends of the fixing groove, and the end of the fixing block abuts against the circumferential side wall of the extension rod.
[0008] Preferably, the side wall of the locking rod body is provided with external threads near both ends, and the locking rod body is connected to a fixing sleeve through the external threads, with the top of the fixing sleeve abutting against the fixing block.
[0009] Preferably, the locking rod body has rotating grooves at both ends located at the fixed grooves, and the fixed block is rotatably connected to the rotating groove.
[0010] Preferably, a limiting groove is provided on the side wall of the fixing groove, and a limiting block is provided at one end of the side wall of the extension rod near the main body of the locking rod, and the limiting block is slidably connected to the limiting groove.
[0011] Preferably, the end of the extension rod away from the main body of the locking rod has a connecting groove, and the lock head has a threaded connecting rod, which is inserted into the connecting groove.
[0012] Preferably, a second fixing sleeve is rotatably connected to the side wall of the extension rod near the outer end, and the second fixing sleeve is threadedly connected to the threaded connecting rod.
[0013] Preferably, a rotating groove is provided on the side wall of the extension rod near the outer end, a limiting ring is provided at the bottom of the second fixing sleeve, the limiting ring is rotatably connected in the rotating groove, and a threaded ring is provided on the upper part of the second fixing sleeve, the threaded ring is threadedly connected to the threaded connecting rod.
[0014] Preferably, the outer end of the extension rod is provided with a second limiting groove at the connecting groove, and a second limiting block is provided on the circumferential side wall of the threaded connecting rod near the bottom end, and the second limiting groove and the second limiting block are slidably connected.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Place the extension rod in the fixing slot and adjust its extension length. Rotating the fixing sleeve will cause the rotating sleeve to move upward. The top of the fixing sleeve pushes the fixing block to rotate and clamp the extension rod. At this time, the extension rod is clamped and fixed. Through this structural design, the overall length of the locking rod can be adjusted, making it more applicable.
[0017] 2. The threaded ring is connected to the threaded connecting rod by a thread, which can push the threaded connecting rod to move downward. When the threaded connecting rod moves downward to the bottom of the connecting groove, the lock head is fixed. The same applies when the lock head needs to be removed, which facilitates the installation and removal of the lock head and makes it easy to replace the lock head.
[0018] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and adjusts the overall length of the locking rod by extending and retracting the extension rod within the locking rod body to adapt to containers of different specifications. It has a wide range of applications and high social value and application prospects. Attached Figure Description

[0029] Both ends of the locking rod body 1 are provided with fixing grooves 101, which are slidably connected to one end of the extension rod 2. A limiting groove 14 is provided on the side wall of the fixing groove 101. A limiting block 201 is provided on the side wall of the extension rod 2 near the locking rod body 1, and the limiting block 201 is slidably connected to the limiting groove 14 to limit the rotational freedom of the extension rod. Rotation grooves 12 are provided at both ends of the locking rod body 1 at the fixing grooves 101, and fixing blocks 13 are rotatably connected within the rotation grooves 12. The ends of the fixing blocks 13 are connected to the extension rod. The lock rod body 1 has external threads 15 near both ends on the side wall of the lock rod body 1. The lock rod body 1 is connected to a fixing sleeve 16 through the external threads 15. The extension rod 2 is placed in the fixing groove 101 and its extension length is adjusted. Rotating the fixing sleeve 16 can drive the rotating sleeve 16 to move upward. The top of the fixing sleeve 16 pushes the fixing block 13 to rotate and clamp the extension rod 2. At this time, the extension rod 2 is clamped and fixed. Through this structural design, the overall length of the lock rod can be adjusted, making it more applicable.
[0030] The extension rod 2 has a connecting groove 202 at the end away from the locking rod body 1. The lock head 3 has a threaded connecting rod 31, which is inserted into the connecting groove 202.
