Protective screening device for semi-trail trailer

Abstract

The invention discloses a protective screening device for a semi-trail trailer. The protective screening device comprises a storage box and a connecting shaft. Through holes are formed at upper and lower ends of the storage box, bearing sleeves are installed in the through holes, the connecting shaft is installed in the storage box through the bearing sleeves, a coil spring is arranged on the lower portion of the connecting shaft, one end of the coil spring is fixed to the inner wall of the storage box, and the other end of the coil spring is fixed to the outer wall of the connecting shaft. Ascreening collecting wheel is further fixed to the outer wall of the connecting shaft, the outer wall of the screening collecting wheel is wrapped with a protective screening, one end of the protective screening is fixed to the screening collecting wheel, and a handle is fixed to the other end of the protective screening. The protective screening device for the semi-trail trailer has the advantages of reasonable structure design and convenient use, through the combination of the storage box, the connecting shaft and the screening collecting wheel, the storage of the protective screening is realized, the feeding and discharging of goods are facilitated, in addition, the handle is designed to be in a tubular shape, the grasping is more convenient, and the fixation more firm.

Description

technical field [0001] The invention relates to the technical field of protective net equipment for a semi-trailer, in particular to a protective net device for a semi-trailer. Background technique [0002] With the rapid development of semi-trailers, the semi-trailer manufacturing industry has achieved unprecedented development. After a long period of development, my country's semi-trailer manufacturing industry has become more and more specialized, with higher and higher technological content, and more intense competition. Therefore, every enterprise must improve its own production technology in order to be competitive in the market. In the existing semi-trailer, after the goods are placed, the operator needs to cover the goods with a protective net to prevent the goods from falling off the trailer during transportation, and the protective net structure usually needs to be pulled and recovered manually , the operator needs to climb onto the cargo to operate, which is inc...
