Description

Technical Field

[0001] This utility model relates to the field of cargo fixing technology, and in particular to a fixing base for cargo boxes. Background Technology

[0002] In the field of freight transportation, especially in road freight scenarios, cargo boxes are usually placed in the truck bed on pallets for transshipment. Currently, to prevent cargo boxes from shifting or tipping over during vehicle start-stop and turning, straps are generally used to secure the pallets to the anchor points in the truck bed. However, straps can only fix the pallets in the truck bed, while the goods on the pallets still need to be secured to the pallets by other means. Moreover, the effectiveness of the straps depends on the force of manual operation, and the tightness is difficult to control precisely. Straps are vulnerable parts, and they are prone to aging and breakage when subjected to high tension due to long-term pulling and friction, posing a safety hazard of goods falling off.

The clamping assembly is connected to the inner wall of the base for clamping the cargo. The clamping assembly includes a first connecting member fixedly connected to the inner wall of the base, a clamping plate hinged to the first connecting member, and a telescopic top rod hinged to the end of the first connecting member away from the clamping plate. A connecting mechanism is provided between one end of the telescopic top rod and the clamping plate for enclosing the first connecting member, the clamping plate, and the telescopic top rod to form a triangular support structure. The telescopic clamping assembly includes a second connecting member connected to the outer wall of the base body via a connecting post and an extension rod threadedly connected to the second connecting member. The extension rod can be adjusted in length by screwing in the thread and abuts against the inner wall of the cargo box.

[0005] Preferably, both the first connecting member and the second connecting member include a fixed plate and a movable plate that is slidably connected to the fixed plate. The fixed plate has a plurality of positioning holes along its length extension direction, and the movable plate has a positioning pin that can be inserted into the positioning holes.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] Reference Figures 1-4As shown, a fixed base for cargo boxes includes a base 1 for placing cargo. The base 1 can be similar to a pallet used in traditional cargo transportation, and its size is not limited. The preferred material is metal to improve durability. However, unlike traditional pallets, when cargo is placed on a traditional pallet, it is necessary to separately bind the cargo to the pallet. In addition, the pallet located in the vehicle compartment needs to be secured during transportation. Therefore, this solution makes the following improvements: A clamping assembly is also provided on the inner wall of the base 1. The clamping assembly includes a first connecting member 2 fixedly connected to the inner wall of the base 1, a clamping plate 3 hinged to the first connecting member 2, and a telescopic top rod 4 hinged to the end of the first connecting member 2 away from the clamping plate 3. A connecting mechanism 5 is provided between one end of the telescopic top rod 4 and the clamping plate 3 to form a triangular support structure by enclosing the first connecting member 2, the clamping plate 3 and the telescopic top rod 4. The number of clamping assemblies can be set to multiple sets, such as two sets or four sets, which are arranged relative to each other. After the cargo box is placed on the base 1, the clamping plate 3 is first pressed against the outer wall of the cargo box, and then the telescopic top rod 4 is connected to the clamping plate 3 through the connecting mechanism 5 to form a triangular structure to clamp and fix the cargo on the base 1. In order to fix the base 1 and prevent it from shaking in the carriage during transportation, a telescopic clamping assembly is provided on the outer wall of the base 1. The telescopic clamping assembly includes a second connecting member 6 connected to the outer wall of the base 1 body through a connecting column 12 and an extension rod 7 threadedly connected to the second connecting member 6. The extension rod 7 can be adjusted in length by screwing in the thread and abuts against the inner wall of the carriage to fix the base 1. The telescopic clamping assembly is at least one set. If the carriage size is small, one side of the base 1 can abut against the carriage, and the other side can abut against the inner wall of the other side of the carriage through the telescopic clamping assembly. Multiple sets can also be provided to fix the base 1 from both sides. By cooperating with the clamping assembly, a double rigid fixation of the cargo box and the base, and the base and the carriage can be achieved.

[0016] Reference Figure 2 As shown, further, in order to accommodate the distance between the goods on the base 1 and the inner wall of the base 1, as well as the distance between the outer wall of the base 1 and the inner wall of the carriage, both the first connecting member 2 and the second connecting member 6 include a fixed plate 8 and a movable plate 9 slidably connected to the fixed plate 8. The fixed plate 8 has multiple positioning holes 10 along its length extension direction. The movable plate 9 is fitted with positioning pins 11 that can be inserted into the positioning holes 10. By inserting the positioning pins 11 into different positioning holes, the length of the first connecting member 2 and the second connecting member 6 can be adjusted so that the clamping plate 3 or the extension rod 7 is as close as possible to the cargo box or the inner wall of the carriage.

[0017] The second connecting member 6 is pivotally connected to the connecting column 12, and a retainer 13 is threaded onto the connecting column 12. When the retainer 13 moves to the outside of the second connecting member 6, the second connecting member 6 and the connecting column 12 are on the same straight line, forming a limit on the second connecting member 6. When the second connecting member 6 comes into contact with the inner wall of the carriage, it will not swing, thus improving the stability of the fixation. When the second connecting member 6 needs to be stored, the retainer 13 is rotated in the opposite direction to release it from the limit on the second connecting member 6. At this time, the second connecting member 6 can swing around the pivot point with the connecting column 12 and move towards the outer wall of the base 1. A clamp 14 is provided on the outer wall of the base 1, and the second connecting member 6 can be inserted into the clamp 14 to fix it.

[0018] Reference Figure 2 As shown, the telescopic top rod 4 further includes a fixed-length rod 15 hinged to the fixed plate 8 on the first connecting member 2 and an extension rod 16 threadedly connected to the fixed-length rod 15. After the length of the first connecting member 2 is adjusted, the extension rod 16 can be rotated to adjust its length so that the connecting mechanism 5 at the end can abut against the clamping plate 3, thereby fixing the cargo box relative to the clamping plate 3. In order to facilitate the threaded rotation of the extension rod 16 and the extension rod 7, a polygonal structure can be provided on its exterior to facilitate rotation operation with tools such as wrenches.

[0019] Reference Figure 2 As shown, the connecting mechanism 5 further includes a toothed seat 17 hinged to the end of the extension rod 16 and a toothed groove 18 provided on the clamping plate 3. When the end of the extension rod 16 is close to the clamping plate 3, the extension rod 16 can be pressed against the clamping plate 3 by the toothed seat 17 being inserted into the toothed groove 18.
