[0001] This utility model relates to the field of container locking bar technology, and in particular to a container locking bar that can be quickly disassembled and assembled. 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 commonly used container locking bar device is to fix the locking bar to the outside of the container door panel through two large upper and lower brackets and a small middle bracket. The locking bar is a locking bar body made of steel pipe in the middle. Lock heads are welded to the upper and lower ends of the locking bar body. A limiting sleeve is fixed on the locking bar body to prevent the locking bar body from moving axially in the large bracket, as well as a handle for rotating and locking the locking bar body.

[0003] In maritime container shipping, the efficiency of port loading and unloading has a significant impact on the timeliness of the entire logistics chain. Traditional container locking bars are cumbersome to assemble and disassemble, and the overall weight of the locking bars is relatively large, making installation time-consuming and labor-intensive for workers. To shorten container turnaround time, improve port operational efficiency, and meet the urgent needs of the logistics industry for efficient transportation, a container locking bar that can be quickly assembled and disassembled is proposed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a container locking bar that can be quickly assembled and disassembled.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-assembly and disassembly container locking bar includes a locking bar body, with end bars detachably and fixedly connected to both ends of the locking bar body. The end of the end bar away from the locking bar body is provided with a lock head. The locking bar body has connecting grooves at both ends, and the end of the end bar near the locking bar body is provided with a connecting block. The connecting block engages with the connecting groove.

[0007] A sliding block is movably connected to the side wall of the connecting block, and a sliding groove is provided on the inner side wall of the connecting groove. A fixed ring is provided in the sliding groove, and a movable ring is slidably connected above the fixed ring in the sliding groove.

[0008] Preferably, a limiting block is provided on the side wall of the connecting groove near the top, and a limiting groove is formed on the side wall of the connecting block, and the limiting block slides within the limiting groove.

[0009] Preferably, the side wall of the connecting block is provided with a sliding groove, and the sliding block is movably connected in the sliding groove.

[0010] Preferably, a spring is provided in the groove, and the movable end of the spring is fixedly connected to the sliding block.

[0011] Preferably, the outer wall of the end rod is connected to a limiting sleeve by an external thread, and the side wall of the locking rod body is provided with a limiting ring, with the bottom end of the limiting sleeve abutting against the top end of the limiting ring.

[0012] Preferably, the main body of the locking rod is provided with a small bracket, and the end rod is provided with a large bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: when the connecting block is inserted into the connecting groove, the top of the sliding block abuts against the top of the sliding groove, and the bottom of the limiting sleeve abuts against the top of the limiting ring. At this time, the connecting block and the connecting groove are fixed. Rotating the limiting sleeve moves it to both sides. Pressing the end rod allows the connecting block to detach from the connecting groove, thereby realizing the quick installation and disassembly of the locking rod and improving the efficiency of port operations.

[0014] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and can reduce port loading and unloading time through the quick assembly and disassembly characteristics of the prefabricated locking bar, thus having high social use value and application prospects.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] Reference Figure 1-6 A quick-release container locking bar includes a locking bar body 1, with end bars 2 detachably and fixedly connected to both ends of the locking bar body 1. A lock head 3 is provided at the end of the end bar 2 away from the locking bar body 1. The lock head 3 is engaged with a lock seat on the container door frame to lock the container door. A small bracket 102 is provided on the locking bar body 1, which is fixedly connected to the container door. A large bracket 21 is provided on the end bar 2, which is fixedly connected to the container door.

[0026] The locking rod body 1 has connecting grooves 12 at both ends, and the end rod 2 has a connecting block 23 at one end near the locking rod body. The connecting block 23 is engaged with the connecting groove 12.

[0027] A limiting block 121 is provided on the side wall of the connecting groove 12 near the top. A limiting groove 2301 is provided on the side wall of the connecting block 23. The limiting block 121 slides in the limiting groove 2301. With this design, the connecting block 23 is inserted into the connecting groove 12, preventing the connecting block 23 from rotating relative to the connecting groove 12.

[0028] The connecting block 23 has a sliding groove 231 on its side wall, and a sliding block 232 is slidably connected in the sliding groove 231. The outer end face of the sliding block 232 is inclined. A spring 233 is provided in the sliding groove 231. The movable end of the spring 233 is fixedly connected to the sliding block 232. The inner side wall of the connecting groove 12 has a sliding groove 123. The outer side wall of the end rod 2 is threaded with a limit sleeve 241 through an external thread 24. The side wall of the locking rod body 1 has a limit ring 101. The bottom end of the limit sleeve 241 abuts against the top end of the limit ring 101. When the connecting block 23 is inserted into the connecting groove 12, the top end of the sliding block 232 abuts against the top end of the sliding groove 123, and the bottom end of the limit sleeve 241 abuts against the top end of the limit ring 101. At this time, the connecting block 23 is fixed to the connecting groove 231.

[0029] A fixed ring 1231 is provided in the sliding groove 123. A movable ring 1232 is slidably connected above the fixed ring 1231 in the sliding groove 123. The cross-section of the movable ring 1232 is a right trapezoid, and the side near the connecting block 23 is a sloping side. When the locking rod needs to be disassembled, the end rod 2 is pressed down, and the top of the movable ring 1232 abuts against the sloping surface of the sliding block 232. The sliding block 232 moves toward the sliding groove 231. When the sliding block 232 moves below the fixed ring 1231, it is reset by the spring 233. The force ejects the sliding block 232. At this time, the top of the sliding block 233 abuts against the inclined surface of the connecting block 23. As the connecting block 23 moves upward, the friction between the top of the sliding block 233 and the inclined surface of the connecting block 23 can drag the movable ring 1232 upward. When the movable ring 1232 moves above the sliding groove 123, the connecting block 23 continues to move upward. At this time, the sliding block 233 is pushed into the sliding groove 231, and the connecting block 23 can be disengaged from the connecting groove 12, thereby realizing the quick installation and disassembly of the locking rod.

[0030] Working principle: When installing the locking bar, first fix the main body 1 of the locking bar to the container door through the small bracket 102. When the connecting block 23 is inserted into the connecting groove 12, the top of the sliding block 232 abuts against the top of the sliding groove 123, and the bottom of the limiting sleeve 241 abuts against the top of the limiting ring 101. At this time, the connecting block 23 and the connecting groove 231 are fixed, realizing the quick and labor-saving installation of the locking bar.

[0031] During disassembly, rotate the limiting sleeve 241 and move it to both sides. At this time, the end rod 2 has space to move towards the locking rod body 1. Press the end rod 2, and the top of the movable ring 1232 abuts against the inclined surface of the sliding block 232. The sliding block 232 moves towards the slide groove 231. When the sliding block 232 moves below the fixed ring 1231, the sliding block 232 is popped out by the restoring force of the spring 233. At this time, the top of the sliding block 233 abuts against the inclined surface of the connecting block 23. While the connecting block 23 moves upward, the friction between the top of the sliding block 233 and the inclined surface of the connecting block 23 can drag the movable ring 1232 upward. When the movable ring 1232 moves above the sliding groove 123, the connecting block 23 continues to move upward. At this time, the sliding block 233 is pushed into the slide groove 231, and the connecting block 23 can be separated from the connecting groove 12, thereby realizing the quick installation and disassembly of the locking rod.
