Description

Technical Field

[0001] The utility model belongs to the technical field of cargo stoppers and relates to a cargo stopper. Background Art

[0002] In land transportation, it is very common to transport goods by road and truck. For goods in container trucks or vans, ordinary ropes cannot achieve the purpose of fixing the goods for transportation, causing the goods to move during transportation, resulting in damage to the goods.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses a cargo support device [patent application number: 201410441159.7; application announcement number: CN104192050B]. The cargo support device includes an outer tube and an inner tube partially located inside the outer tube, the inner tube extends outward from the outer end of the outer tube, a handle is hinged on the outer tube, and a ratchet is provided at the inner end of the handle, a rack is fixed at the outer end of the inner tube by a fastener, and a plurality of teeth that can mesh with the ratchet are provided on the rack along its axial direction, an extension tube is provided on the outer tube sleeve, and a plurality of opposite adjustment holes are arranged along its axial direction on the side of the extension tube, and opposite positioning holes are correspondingly provided on the inner end side of the outer tube, and a positioning member is provided between the outer tube and the extension tube for connecting the two or separating the two when the positioning hole is opposite to one of the adjustment holes.

[0004] The cargo supporter of this structure can be adjusted in length, so that the foot pad can be closely attached to the inner wall of the container, so that the cargo supporter is positioned, and the cargo supporter can support the cargo. However, the outer wall of the foot pad of the cargo supporter of this structure has a concave and convex anti-skid surface, and the inner wall of the container is a relatively flat surface. The anti-skid surface of the foot pad is closely attached to the inner wall of the container, so that the cargo supporter is positioned, which is a surface-to-surface contact. However, during the transportation of the truck, there is a problem that the cargo supporter as a whole slides down from top to bottom, so that the cargo supporter leaves the set position, fails to play the role of supporting the cargo, and has low stability.
