Description

Technical Field

[0001] This utility model relates to the field of container locking bar technology, and in particular to a modular quick-release 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 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, port loading and unloading efficiency has a significant impact on the timeliness of the entire logistics chain. Traditional container locking bars are cumbersome to assemble and disassemble, consuming a lot of time and manpower. In contrast, modular quick-release locking bars can be quickly assembled and disassembled, significantly shortening container turnaround time, improving port operational efficiency, and meeting the logistics industry's urgent need for efficient transportation. The quick-assembly and disassembly characteristics of modular quick-release locking bars can reduce port loading and unloading time, increase ship turnaround rate, and reduce port operating costs. At the same time, its modular structure, which allows for partial replacement, also helps to reduce maintenance costs and extend the service life of the locking bars. Therefore, a modular quick-release container locking bar capable of rapid assembly and disassembly is proposed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a modular quick-release container locking bar.

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

[0006] A modular quick-release container locking bar includes a bar body, with assembly rods detachably and fixedly connected to both ends of the bar body. The assembly rods are provided with lock heads on the sides away from the bar body, and a handle is provided on the bar body.

[0007] Both ends of the locking rod body are provided with connecting grooves. The side end of the assembly rod near the rod body body is provided with a connecting block. The connecting block is engaged with the connecting groove. The side wall of the connecting block is provided with a sliding groove. A slider is slidably connected inside the sliding groove. The side wall of the connecting groove is provided with a limiting groove. The slider is engaged with the limiting groove.

[0008] Preferably, a spring is provided inside the sliding groove, and the movable end of the spring is fixedly connected to the slider and maintains a spring pressure on the slider in the outward direction.

[0009] Preferably, a sliding sleeve is slidably connected to the side wall of the rod body, and a driving block is provided at the top of the sliding sleeve, the driving block extending into the limiting groove.

[0010] Preferably, the main body of the rod has a groove located below the groove on its side wall, and the sliding sleeve is slidably connected in the groove.

[0011] Preferably, a limiting ring is provided at the bottom of the side wall of the sliding sleeve, and a limiting sleeve is connected to the side wall of the assembly rod near the connecting block by an external thread, and the limiting sleeve abuts against the limiting ring.

[0012] Preferably, the assembled rod is provided with a bracket, and the bracket is fixedly connected to the container door frame;

[0013] Preferably, the rod body is provided with a fixed seat, and the handle is connected to the fixed seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When the connecting block is fully inserted into the connecting groove, the spring's restoring force will eject the slider. At this point, the slider engages with the limiting groove, fixing the rod body to the assembly rod. As the drive block moves upward, it pushes the slider into the sliding groove, releasing the engagement between the slider and the limiting groove. The assembly rod can then be removed from the rod body. The locking rod is easy to disassemble and install, reducing port loading and unloading time, increasing ship turnaround rate, and lowering port operating costs. Furthermore, its modular structure, allowing for partial replacement, also helps reduce maintenance costs and extend the locking rod's service life.

[0016] 2. The limiting sleeve can be fixed by abutting against the limiting ring, which increases the connection strength between the assembly rod and the main body of the rod, and at the same time can prevent the assembly rod from accidentally touching the limiting sleeve and causing it to detach from the main body of the rod.

[0017] 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

[0027] 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.

[0028] Example 1

[0029] Reference Figure 1-7 A modular quick-release container locking bar includes a bar body 1, with assembly rods 2 detachably and fixedly connected to both ends of the bar body 1. The side end of the assembly rod 2 away from the bar body 1 is provided with a lock head 3, which is engaged with a lock seat on the container door frame to fix the container door. A handle 4 is provided on the bar body 1.

[0030] Both ends of the locking rod body 1 are provided with connecting grooves 13. The side end of the assembly rod 2 near the rod body body 1 is provided with a connecting block 23. The connecting block 23 is engaged with the connecting groove 13. By inserting the connecting block 23 into the connecting groove 13 and fixing the two, the assembly of the rod body body 1 and the assembly rod 2 can be completed.

[0031] The connecting block 23 has a sliding groove 231 on its side wall. A slider 233 is slidably connected inside the sliding groove 231. The outer end face of the slider 233 is inclined. A spring 232 is provided inside the sliding groove 231. The movable end of the spring 232 is fixedly connected to the slider 233 and keeps pressing the slider 233 outward. A limiting groove 131 is provided on the side wall of the connecting groove 13. The slider 233 is engaged with the limiting groove 131. When the connecting block 23 is inserted into the connecting groove 13, the slider 233 will abut against the top of the side wall of the connecting groove 13, pushing the slider 233 to slide into the sliding groove 231. At this time, the spring 232 is in a compressed state. When the connecting block 23 is fully inserted into the connecting groove 13, the restoring force of the spring 232 can pop out the slider 233. At this time, the slider 233 is engaged with the limiting groove 131, which can fix the rod body 1 and the assembly rod 2. The assembly of the locking rod can be achieved simply by inserting the connecting block 23 into the connecting groove 13.

[0032] Furthermore, a slide groove 14 is provided on the side wall of the rod body 1 below the slide groove 131. A slide sleeve 141 is slidably connected to the side wall of the slide groove 14. A drive block 143 is provided at the top of the slide sleeve 141. The drive block 143 extends into the limiting groove 131. When it is necessary to disassemble the locking rod, the slide sleeve 141 is pushed upward so that it moves towards the limiting groove 131 in the slide groove 14. While the drive block 143 moves upward, it can push the slider 233 into the slide groove 231. At this time, the slider 233 is disengaged from the limiting groove 131, and the assembly rod 2 can be removed from the rod body 1, which facilitates the disassembly of the locking rod.

[0033] Furthermore, a limiting ring 142 is provided at the bottom of the side wall of the sliding sleeve 141. A limiting sleeve 241 is threadedly connected to the side wall of the assembly rod 2 near the connecting block 23 via an external thread 24. The limiting sleeve 241 abuts against the limiting ring 142. When installing the assembly rod 2, the limiting sleeve 241 can be fixed by abutting against the limiting ring 142. This increases the connection strength between the assembly rod 2 and the rod body 1, while preventing accidental contact with the limiting sleeve 241 that could cause the assembly rod 2 to detach from the rod body 1.

[0034] Furthermore, the assembly rod 2 is provided with a bracket 11, which is fixedly connected to the container door frame.

[0035] Furthermore, a fixed seat 12 is provided on the main body 1 of the rod, and the handle 4 is connected to the fixed seat 12.

[0036] Working principle: When assembling the locking rod, when the connecting block 23 is inserted into the connecting groove 13, the slider 233 will abut against the top of the side wall of the connecting groove 13, pushing the slider 233 to slide into the sliding groove 231. At this time, the spring 232 is in a compressed state. When the connecting block 23 is fully inserted into the connecting groove 113, the restoring force of the spring 232 can pop out the slider 233. At this time, the slider 233 is engaged with the limiting groove 131, which can fix the rod body 1 and the assembly rod 2. When the limiting sleeve 241 is rotated, the limiting sleeve 241 abuts against the limiting ring 142. While increasing the connection strength between the assembly rod 2 and the rod body 1, it can prevent the assembly rod 2 from being separated from the rod body 1 due to accidental contact with the limiting sleeve 241.

[0037] When disassembling the locking rod, rotate the limiting sleeve 241. The limiting sleeve 241 moves towards both ends of the locking rod. At this time, push the sliding sleeve 141 so that it moves towards the limiting groove 131 in the sliding groove 14. While the driving block 143 moves upward, it can push the slider 233 into the sliding groove 231. At this time, the slider 233 and the limiting groove 131 are disengaged. The assembly rod 2 can then be removed from the rod body 1.
