A pull-out support

Abstract

The invention provides a withdrawing tomming device, and belongs to the technical field of machines. The problem that an existing tomming device is inconvenient to use is solved. The withdrawing tomming device comprises a connecting piece, a main supporting beam and a telescopic short beam, wherein the main supporting beam comprises a first supporting beam and a second supporting beam, the telescopic short beam is connected with the first supporting beam, the first supporting beam is inserted into the second supporting beam and can slide back and forth, and a locking structure is arranged between the first supporting beam and the second supporting beam; the second supporting beam is hinged to the connecting piece and can swing toward the lower side, a receding notch is formed between the end face of the end, close to the connecting piece, of the second supporting beam and the lower side face, and a limiting structure capable of limiting the second supporting beam from swinging toward the upper side when the second supporting beam and the connecting piece are kept in the same straight line state. When not used, the tomming device can swing downwards, is tightly attached to the inner wall of a carriage and therefore does not affect loading and unloading of the carriage, the whole process can be completed just by one person, goods are not lost easily, and use convenience is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a pull-out cargo support. Background technique [0002] Cargo on a motor vehicle must be secured during transport to prevent shifting. For ordinary trucks, ropes can be directly used for binding. But for the goods in the container or box truck, common rope just can't reach the purpose of fixed transportation goods, in order to solve this problem, people have designed various fixing tools, and the cargo support is exactly one of them. [0003] Guide rails are installed on the inner walls of some existing containers, and the two ends of the pull-type cargo holders have locking pieces, which can be clipped and positioned on the guide rails to realize the positioning of the cargo holders. For example, the U.S. Patent Application (Application No. US005941667A) discloses a structure of a pull-type cargo support, including connectors, support beams and telescopic short beams, the conn...

AI Technical Summary

Problems solved by technology

The above-mentioned cargo support has the following defects: 1. During the installation and disassembly of the cargo support, one person needs to hold the cargo support first, and then another person clamps the two ends of the cargo support into the guide rails on the inner wall of the carriage Lock and lock, that is to say, the whole process requires the cooperation of at least two people to complete, and the operation is troublesome and inconvenient

2. When there is no need to use the cargo support, it is necessary to remove the entire cargo support from the carriage, which is more troublesome. Moreover, it is easy to cause loss of the cargo support after being removed and stored separately, which is more inconvenient
