Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, specifically a cargo securing device for road freight transportation. Background Technology

[0002] In the field of road freight transport, the stable securing of goods during transportation is a key aspect of ensuring transport safety and preventing damage to goods. Currently, common methods of securing goods on the market mainly rely on manual binding straps, wooden supports, or simple buckle structures. These methods generally have the following problems: Manual binding straps rely on manual tightening, making it difficult to precisely control the tension. They also lack a reliable self-locking structure. During long-distance transportation, the binding straps are prone to loosening due to road conditions such as bumps and sudden braking, causing goods to shift or tip over. This can result in minor damage to the goods or even traffic accidents. Simple buckle structures have limited load-bearing capacity and are prone to breakage when dealing with heavy goods, failing to provide continuous and stable restraint. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cargo securing device for road freight transport, which has the advantages of adjustable tension and self-locking. This solves the problems of existing manual binding straps having difficulty in controlling tension and being prone to loosening, and simple buckle structures having limited load-bearing capacity and being prone to breakage, leading to easy displacement and damage of goods during transportation and even causing safety accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cargo fixing device for road freight transport, including a slide rail, which can be fixedly installed with a cargo box, a fixing block slidably installed on the top of the slide rail, a fixing seat slidably installed on the top of the slide rail, and a roll-up assembly, which is arranged on the front and rear sides of the slide rail and is used to bind the cargo. The self-locking drive assembly is located inside the fixed base and is used to adjust and lock the unwinding and take-up assemblies.

[0005] As a preferred embodiment of this utility model, the slide rail has a sliding groove inside, and a slider that slides and engages with the sliding groove is slidably installed inside the slide rail. The bottom of the fixing block is fixedly installed with the top of the slider. A bolt is threadedly connected to the rear side of the slider, and a knob is fixedly installed at the top of the bolt.

[0006] As a preferred embodiment of this utility model, a second slider that slides and engages with a sliding groove is slidably installed inside the slide rail. The bottom of the fixed seat is fixedly installed with the top of the second slider. A second bolt is threadedly connected to the front side of the second slider, and a second knob is fixedly installed at the top of the second bolt.

[0007] As a preferred embodiment of this utility model, the slide rail has a positioning hole inside, and a positioning bolt is threaded into the positioning hole. The slide rail can be fixedly installed to the inner wall of the cargo box through the positioning hole and the positioning bolt.

[0008] In a preferred embodiment of this utility model, the self-locking drive assembly includes a mounting plate, a worm gear, a knob, and a worm wheel. The mounting plate is fixedly mounted on the top of the fixed base. The surface of the worm gear is rotatably mounted to the mounting plate. A knob is fixedly mounted on the top of the worm gear through the mounting plate. The worm wheel is located on the rear side of the worm gear and meshes with the worm gear.

[0009] As a preferred embodiment of this utility model, the winding and unwinding assembly includes a fixed shaft, a winding reel, and a binding rope. The fixed shaft is fixedly installed at the center of the worm gear, and both ends of the fixed shaft pass through the fixed seat and are fixedly installed with the winding reel. The binding rope is wound around both sides of the surface of the fixed shaft and is located inside the winding reel.

[0010] As a preferred embodiment of this utility model, a number of fixing rods are fixedly installed inside the fixing block, and the end of the binding rope away from the winding reel is fixedly installed with the fixing rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model solves the problems of existing manual binding straps, such as difficulty in controlling tension and easy loosening, and simple buckle structures with limited load-bearing capacity and easy breakage, which lead to easy displacement and damage of goods during transportation and even safety accidents, by setting up a slide rail, fixing block, fixing seat, winding and unwinding assembly and self-locking drive assembly.

[0012] This invention features a self-locking drive assembly. On one hand, the fixed connection between knob three and the worm, and the meshing between the worm and the worm wheel, allow the worm wheel to be easily driven to rotate simply by turning knob three, providing stable power to the winding and unwinding assembly and reducing operational difficulty. On the other hand, utilizing the self-locking characteristic of the worm and the worm wheel, the worm wheel cannot drive the worm to rotate in the reverse direction after knob three is stopped, automatically locking its own state. This provides a reliable guarantee for the tensioning and locking of the subsequent winding and unwinding assembly, preventing reverse power transmission due to vibration during transportation.

[0013] This utility model, through the setting of a winding and unwinding assembly, with a fixed shaft fixed to the center of the worm gear and both ends connected to the winding reel, can rotate synchronously with the worm gear, driving the winding reel to realize the winding and unwinding operation of the binding rope—rotating forward to release the binding rope to adapt to the size of the goods, and rotating in the reverse direction to tighten the binding rope to fit the surface of the goods; at the same time, the binding rope is wound around both sides of the fixed shaft and located inside the winding reel, which can prevent the binding rope from shifting, tangling and knotting during the winding and unwinding process, ensuring smooth winding and unwinding of the binding rope, and adapting to the binding needs of goods of different heights and widths.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Example 1 Reference Figure 1-4 The first embodiment of this utility model adopts the following technical solution, including a slide rail 1, which can be fixedly installed with the cargo box, a fixing block 31 slidably installed on the top of the slide rail 1, a fixing seat 5 slidably installed on the top of the slide rail 1, and also includes a roll-up assembly, which is set on the front and rear sides of the slide rail 1 and is used to tie up the goods. The self-locking drive component is located inside the fixed base 5 and is used to adjust and lock the unwinding and winding components.

[0021] Specifically, slide rail 1 serves as the installation base. Based on the internal length of the cargo box and the usual cargo placement area, the installation position and quantity of slide rail 1 can be determined. Slide rail 1 can be fixed on both sides of the bottom of the cargo box inner wall, ensuring that the length direction of slide rail 1 is consistent with the direction of force during cargo transportation (such as the front-to-back direction), and that the two slide rails 1 are parallel and the spacing is adapted to the width of the cargo. If the cargo needs to be fixed vertically or the bottom space is limited, two sets of slide rail 1 can be installed vertically on both sides of the cargo box inner wall (the height is adjusted according to the height of the cargo). Then, according to the size and placement of the cargo, push the fixing block 31 to slide on the top of slide rail 1, and at the same time push the fixing seat 5 to slide on the top of slide rail 1, thereby adjusting the relative position of the two with respect to the cargo. The unwinding length of the winding and unwinding assembly can be controlled by the drive component, thereby adapting to cargo of different heights and widths. After the cargo is fixed, the self-locking drive component can automatically lock the state of the winding and unwinding assembly.

[0022] Example 2 The second embodiment of this utility model adopts the following technical solution: a sliding groove is provided inside the slide rail 1, and a slider 3 that slides and engages with the sliding groove is slidably installed inside the slide rail 1. The bottom of the fixing block 31 is fixedly installed with the top of the slider 3. A bolt 33 is threadedly connected to the rear side of the slider 3. A knob 331 is fixedly installed at the top of the bolt 33. A slider 4 that slides and engages with the sliding groove is slidably installed inside the slide rail 1. The bottom of the fixing seat 5 is fixedly installed with the top of the slider 4. A bolt 41 is threadedly connected to the front side of the slider 4. A knob 411 is fixedly installed at the top of the bolt 41. A positioning hole 11 is provided inside the slide rail 1, and a positioning bolt 2 is threadedly connected inside the positioning hole 11. The slide rail 1 can be fixedly installed with the inner wall of the cargo box through the positioning hole 11 and the positioning bolt 2.

[0023] Specifically, slider 3 and slide rail 1 are slidably engaged via a sliding groove. Fixing block 31 moves freely along slide rail 1 with slider 3. After adjusting to the position suitable for the goods, knob 331 is tightened, and bolt 33 is threadedly connected to slider 3, causing the bottom of bolt 33 to press against the inner wall of slide rail 1, thus fixing slider 3 and slide rail 1 relative to each other and locking the position of fixing block 31. Slider 4 is similarly slidably engaged with slide rail 1 via a sliding groove. Fixing seat 5 slides along slide rail 1 with slider 4. After adjusting its position according to the needs of goods binding, knob 411 is tightened, and bolt 41 is used to connect slider 4 to the slider. The threaded connection of bolt 241 allows the bottom end of bolt 241 to press against the inner wall of slide rail 1, thereby fixing the slider 24 and slide rail 1 relative to each other and locking the position of the fixing seat 5. The positioning hole 11 on slide rail 1 can be flexibly set according to the spacing of the reserved installation holes on the inner wall of the cargo box, so that the adaptation and installation can be completed without additional modification to the cargo box. At the same time, this structure supports the installation of slide rail 1 at multiple positions on the bottom or sides of the cargo box without replacing slide rail 1 itself. It can adapt to different cargo placement requirements such as flat or vertical placement by simply adjusting the installation position of positioning bolt 2, which greatly improves the compatibility of the device with different cargo box structures and cargo types.

[0024] Example 3 The third embodiment of this utility model adopts the following technical solution: the self-locking drive assembly includes a mounting plate 51, a worm gear 52, a knob 3 521, and a worm wheel 53. The mounting plate 51 is fixedly installed on the top of the fixed base 5. The surface of the worm gear 52 is rotatably installed with the mounting plate 51. The knob 3 521 is fixedly installed through the top of the mounting plate 51. The worm wheel 53 is located on the rear side of the worm gear 52 and meshes with the worm gear 52. The take-up and unwinding assembly includes a fixed shaft 54, a take-up reel 6, and a binding rope 61. The fixed shaft 54 ​​is fixedly installed at the center of the worm wheel 53. Both ends of the fixed shaft 54 ​​pass through the fixed base 5 and are fixedly installed with the take-up reel 6. The binding rope 61 is wound around both sides of the surface of the fixed shaft 54 ​​and is located inside the take-up reel 6. Several sets of fixing rods 32 are fixedly installed inside the fixing block 31. The end of the binding rope 61 away from the take-up reel 6 is fixedly installed with the fixing rod 32.

[0025] Specifically, by rotating knob 3 521, the worm 52 rotates synchronously with knob 3 521. Since the worm 52 meshes with the worm wheel 53, it can drive the worm wheel 53 to rotate, thereby driving the fixed shaft 54 ​​fixed at its center to rotate. When the fixed shaft 54 ​​rotates, the winding reels 6 at both ends rotate synchronously, realizing the winding and unwinding operation of the binding rope 61 wound on both sides of the fixed shaft 54. The winding reel 6 rotates forward to release the binding rope 61, and rotates in the opposite direction to tighten the binding rope 61. The end of the binding rope 61 away from the winding reel 6 is connected and fixed to the fixed rod 32 in the fixed block 31, thereby binding the goods. The tension of the binding rope 61 is adjusted by rotating the winding reel 6. At the same time, by utilizing the self-locking characteristic of the meshing of the worm 52 and the worm wheel 53, after the knob 3 521 is stopped, the worm wheel 53 cannot rotate in the opposite direction, so that the binding rope 61 maintains its current tension.

[0026] Working principle: Using the slide rail 1 as the core mounting carrier, the positioning holes 11 inside it form a threaded engagement structure with the positioning bolts 2. This structure allows the slide rail 1 to be reliably fixed to the inner wall of the cargo box. During actual installation, the corresponding installation method is selected according to the cargo box structure and cargo placement requirements. If the cargo is stacked flat and there is sufficient space at the bottom of the cargo box, the installation positions of the two sets of slide rails 1 are determined based on the internal length of the cargo box and the usual cargo placement area. They are then placed parallel to each other on both sides of the bottom of the inner wall of the cargo box, aligning the positioning holes 11 on the slide rail 1 with the pre-drilled mounting holes on the bottom inner wall of the cargo box. The positioning bolts 2 are then passed through the positioning holes 11 and threadedly connected to the mounting holes at the bottom of the cargo box. The positioning bolts 2 are gradually tightened until the slide rail 1 is tightly fitted to the bottom of the cargo box without any looseness, forming a symmetrical bottom mounting reference. Furthermore, ensure that the length direction of slide rail 1 is consistent with the direction of force applied during cargo transportation (such as the front-to-back direction) to provide stable support for subsequent component sliding. If the goods need to be fixed vertically (such as long strips of pipe) or the space at the bottom of the cargo box is limited, then the two sets of slide rails 1 are vertically attached to both sides of the inner wall of the cargo box. Adjust the installation height of slide rail 1 according to the height of the goods so that the positioning holes 11 on slide rail 1 are aligned with the pre-reserved installation holes on both sides of the inner wall of the cargo box. Similarly, fix them by threaded connection with positioning bolts 2. After tightening, check the verticality and stability of slide rail 1 to ensure that the height of slide rail 1 on both sides is consistent, parallel and the length direction is consistent with the height direction of the cargo box, forming a vertical installation benchmark to meet the vertical fixing requirements of goods. Through the cooperation of positioning holes 11 and positioning bolts 2, the overall displacement of slide rail 1 during transportation is effectively prevented. After slide rail 1 is fixed, the component position adjustment stage begins to adapt to goods of different sizes. The sliding groove inside slide rail 1 provides a sliding track for slider 3 and slider 4. The bottom of fixing block 31 is fixedly connected to the top of slider 3, and the bottom of fixing seat 5 is fixedly connected to the top of slider 4. The position adjustment of fixing block 31 and fixing seat 5 is achieved through the cooperation of slider and sliding groove. When adjusting fixing block 31, pushing fixing block 31 will drive slider 3 to move smoothly along the sliding groove until fixing block 31 reaches the position that matches one side of the goods. At this time, tighten knob 331 on the back of slider 3 to drive the bolt fixed to it. 33 moves downward along the thread, so that the bottom end of bolt 33 is tightly pressed against the inner wall of slide rail 1. The friction force fixes slider 3 to slide rail 1, thereby locking the position of fixing block 31 and preventing displacement during subsequent binding. When adjusting fixing seat 5, push fixing seat 5 to drive slider 4 to move synchronously along the sliding groove. Adjust the spacing of fixing seat 5 according to the position of the other side of the goods. After adjustment, tighten knob 411 on the front side of slider 4, so that the bottom end of bolt 41 presses against the inner wall of slide rail 1, thereby fixing slider 4 to slide rail 1 and locking the position of fixing seat 5. Finally, fixing seat 5 and fixing block 31 form a symmetrical constraint on the goods. Finally, the cargo binding and locking are completed through the linkage of the self-locking drive assembly and the take-up and unwinding assembly. The mounting plate 51 in the self-locking drive assembly is fixed to the top of the fixed base 5. The worm gear 52 is rotatably connected to the mounting plate 51, with its top end passing through the mounting plate 51 and fixed to the knob 521. The worm wheel 53 is located behind the worm gear 52 and meshes with it. The fixed shaft 54 ​​of the take-up and unwinding assembly is fixed at the center of the worm wheel 53, with both ends passing through the fixed base 5 and fixed to the take-up reel 6. The binding rope 61 is wound around both sides of the fixed shaft 54 ​​and located inside the take-up reel 6. Its end away from the take-up reel 6 is fixedly connected to the fixed rod 32 inside the fixed block 31. During operation, rotating the knob 521 drives the worm gear 52 to rotate synchronously. Because the worm gear 52 meshes with the worm wheel 53, the worm wheel 53 is... The drive rotates and drives the fixed shaft 54 ​​to rotate. The fixed shaft 54 ​​further drives the winding reels 6 at both ends to rotate synchronously, realizing the winding and unwinding operation of the binding rope 61. When the winding reel 6 rotates forward, the binding rope 61 is released, and when it rotates in reverse, the binding rope 61 is tightened. After connecting the binding rope 61 to the fixed rod 32, the knob 3 521 is rotated to make the winding reel 6 rotate in the reverse direction, tightening the binding rope 61 until it is tightly attached to the surface of the goods and reaches the preset tension. At this time, the knob 3 521 is stopped. Utilizing the meshing and self-locking characteristics of the worm gear 52 and the worm wheel 53, the worm wheel 53 remains stationary, thereby stopping the rotation of the fixed shaft 54 ​​and the winding reel 6. The binding rope 61 always maintains the current tension and will not loosen due to the vibration of the goods or the action of external forces, ultimately achieving stable fixation of the goods.

[0027] In summary, by combining the slide rail, fixing block, fixing seat, winding and unwinding assembly, and self-locking drive assembly, the problems of difficult tension control and easy loosening of existing manual binding straps, and the limited load-bearing capacity and easy breakage of simple buckle structures have been solved, which lead to easy displacement and damage of goods during transportation and even safety accidents.
