Cargo fixing and binding device for logistics transportation

Abstract

This utility model provides a cargo securing strap device for logistics transportation, comprising: a hook assembly, a locking disc assembly rotatably connected to the inner wall of the hook assembly, a dynamic limiting component installed on the inner wall of the hook assembly, and a clamping and positioning component installed on the inner wall of the locking disc assembly. Limiting structures are symmetrically installed on the inner walls at both ends of the hook assembly and the locking disc assembly. The cargo securing strap device provided by this utility model, through the combined use of the dynamic limiting component and the clamping and positioning component, can perform structural positioning when the buckle is closed and positioned, forming a structural positioning guide. This can directly offset the positional displacement of the buckle caused by installation operation deviations or minor deformations of components. Furthermore, after the buckle is positioned and installed, the clamping and positioning component can immediately apply a sliding locking force to the buckle, forming a dual structural constraint of positioning and clamping, effectively preventing slight loosening of the workpiece due to the buckle not being fixed before clamping.

Description

Technical Field

[0001] This utility model relates to the field of locking strap technology, and in particular to a cargo securing strap device for logistics transportation. Background Technology

[0002] In the logistics and transportation sector, cargo securing straps are a core component for ensuring cargo safety. They are widely used in trucks, containers, engineering vehicles, and other scenarios. Their core function is to generate restraint through the cooperation of buckles and straps to prevent cargo from shifting or loosening during transportation due to bumps or turns.

[0003] The existing device lacks a dynamic limiting structure, and the locking position relies entirely on manual operation. During installation, if the operator applies force at an off-angle or the locking housing undergoes slight deformation due to long-term use, the locking may fail to accurately engage with the preset slot, resulting in misalignment. Furthermore, the single locking direction can easily cause the strap to loosen.

[0004] Therefore, it is necessary to provide cargo securing devices for logistics transportation to solve the above-mentioned technical problems. Summary of the Invention

[0005] This utility model provides a cargo securing strap device for logistics transportation, which solves the problems of frequent positioning deviations of existing locks, the need for repeated structural calibration, and asynchronous positioning and clamping.

[0006] To solve the above-mentioned technical problems, the cargo securing strap device for logistics transportation provided by this utility model includes: a hook assembly, a locking disc assembly rotatably connected to the inner wall of the hook assembly, the hook assembly cooperating with the locking disc assembly for positioning the strap, a dynamic limiting component installed on the inner wall of the hook assembly, a clamping positioning component installed on the inner wall of the locking disc assembly, the dynamic limiting component cooperating with the clamping positioning component for structural positioning of the locking disc assembly, and limit structures symmetrically installed on the inner walls of both ends of the hook assembly and the locking disc assembly.

[0007] Preferably, the locking hook assembly includes a limiting lock member, an installation structure is installed on the inner wall of the front end of the limiting lock member, the installation structure is used for installing the strap structure, and a ratchet structure is installed on the inner wall of the rear end of the limiting lock member.

[0008] Preferably, the locking disc assembly includes a connecting plate, an inner wall of which is fitted with a safety buckle structure for positioning and securing the strap, and an inner wall of the connecting plate is fitted with a wrapping element.

[0009] Preferably, the dynamic limiting component includes a support frame, an installation frame is installed on the inner wall of the support frame, guide structures slide on the inner walls at both ends of the installation frame, a first wedge is installed on the side end of the guide structure, an elastic support is installed on the inner wall of the first wedge, the elastic support is used for elastic support of the first wedge, a fixing block is installed on the side end of the guide structure, a positioning structure is installed on the top of the fixing block, and the positioning structure is used for structural positioning of the locking disc assembly.

[0010] Preferably, the clamping and positioning component includes an extension mounting member, a support frame is mounted on the inner wall of the extension mounting member, second wedge-shaped members are symmetrically mounted at both ends of the support frame, and a slot structure is symmetrically opened on the inner wall at both ends of the support frame. The slot structure is used to dynamically restrict the structural clamping of the component.

[0011] Preferably, the limiting structure includes a support plate, a guide frame structure is installed on the inner wall of the bottom support plate, and a guide rod structure is installed on the inner wall of the top support plate. The guide frame structure, in conjunction with the guide rod structure, can be used for position guidance of the locking hook assembly and the locking disc assembly.

[0012] Compared with related technologies, the cargo securing strap device for logistics transportation provided by this utility model has the following advantages: This utility model provides a cargo securing strap device for logistics transportation. During installation and use, to reduce loosening of the strap, a dynamic limiting component and a clamping positioning component work together to perform structural positioning when the buckle is closed and positioned, forming a structural positioning guide. This directly counteracts positional shifts caused by installation deviations or minor component deformations, eliminating the need for repeated manual calibration and significantly reducing the probability of buckle misalignment. It ensures that the buckle is in the preset working position after each installation, providing a precise benchmark for subsequent fixing. Furthermore, after the buckle is positioned and installed, the clamping positioning component immediately applies a sliding locking force to the buckle, forming a dual structural constraint of positioning and clamping. This effectively prevents slight loosening of the workpiece before clamping due to the buckle not being securely fixed. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the cargo securing strap device for logistics transportation provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the locking disc assembly.

[0018] When installing and using the strap, one end of the strap can be installed on the inner wall of the mounting structure 12 to form a stable installation adjustment, and the ratchet structure 13 set on the right end can facilitate the rotation and locking of the locking disc assembly 2.

[0021] When the strap is closed, the wrapping member 23 on the inner wall can ensure that the strap is securely fastened. At the same time, when the strap is used for binding, the hook at one end can be fastened to the safety buckle structure 22 to ensure the stability of the strap.

[0022] Among them, the lock disk assembly 2 includes, but is not limited to, a mechanical limit lock disk and a combination lock disk; in this embodiment, the lock disk assembly 2 is preferably a mechanical limit lock disk.

[0023] The dynamic limiting component 3 includes a support frame 31, an installation frame 32 is installed on the inner wall of the support frame 31, guide structures 33 slide on the inner walls at both ends of the installation frame 32, a first wedge 34 is installed on the side end of the guide structure 33, an elastic support 35 is installed on the inner wall of the first wedge 34, the elastic support 35 is used for elastic support of the first wedge 34, a fixing block 36 is installed on the side end of the guide structure 33, and a positioning structure 37 is installed on the top of the fixing block 36, the positioning structure 37 is used for structural positioning of the locking disc component 2.

[0024] When the locking hook assembly 1 and the locking disc assembly 2 are closed and locked, the clamping and positioning assembly 4 will contact the first wedge 34 in advance to limit the structure, and the guide structure 33 will slide on its side. When the guide structure 33 slides, the positioning structure 37 on the right end will slide and clamp onto the inner wall of the clamping and positioning assembly 4, forming the function of limiting the structure and sliding clamping, ensuring the accurate positioning of the structure.

[0025] The dynamic limiting component 3 includes, but is not limited to, a spring-type dynamic limiting component and a hydraulic dynamic limiting component; in this embodiment, the dynamic limiting component 3 is preferably a spring-type dynamic limiting component.

[0030] When the locking hook assembly 1 and the locking disc assembly 2 are structurally closed, the guide rod structure 53 on the inner wall will be synchronously positioned inside the guide frame structure 52 to reduce the installation deviation of the structure.

[0031] The limiting structure 5 includes, but is not limited to, the sliding groove limiting type and the sleeve limiting type; in this embodiment, the limiting structure 5 is preferably the sleeve limiting type.

[0032] The working principle of the cargo securing strap device for logistics transportation provided by this utility model is as follows: During installation and use, the securing strap is first installed on the inner wall of the left end of the hook assembly 1 and then tied to the goods. Next, the strap is clamped onto the inner wall of the disc assembly 2. After the securing strap is installed, the hook assembly 1 and disc assembly 2 are rotated to close. When the disc assembly 2 is closed, the clamping and positioning component 4 on the inner wall automatically positions itself onto the inner wall of the dynamic restraint component 3, forming a clamping mechanism. This reduces the possibility of loosening during use and transportation. Furthermore, when the clamping and positioning component 4 contacts the dynamic restraint component 3, a sliding clamping mechanism is simultaneously formed to further reduce the possibility of loosening and improve the stability of the lock installation.

[0033] Compared with related technologies, the cargo securing strap device for logistics transportation provided by this utility model has the following advantages: During installation and use, to reduce the loosening of the straps, the dynamic limiting component 3 and the clamping positioning component 4 work together to perform structural positioning when the buckle is closed and positioned, forming a structural positioning guide. This directly offsets the positional displacement of the buckle caused by installation operation deviations or minor deformation of components, eliminating the need for repeated manual calibration and significantly reducing the probability of buckle misalignment. This ensures that the buckle is in the preset working position after each installation, providing a precise benchmark for subsequent fixing. Furthermore, after the buckle is positioned and installed, the clamping positioning component 4 can immediately apply a locking force in the sliding direction to the buckle, forming a dual structural constraint of positioning and clamping. This effectively prevents slight loosening of the workpiece due to the buckle not being fixed before clamping.
