Draw-bar box auxiliary device capable of replacing rollers and protecting hands

Abstract

The invention relates to the technical field of draw-bar boxes, and discloses a draw-bar box auxiliary device capable of replacing rollers and protecting hands. The draw-bar box auxiliary device comprises a machine shell, a fixed block is fixedly connected in the machine shell, a first long rod is slidably connected in the fixed block, movable rods are arranged on the two sides of the first long rod, a first push rod is arranged on the upper portion of the first long rod, a second long rod is arranged on the left side of the first push rod, and a supporting rod is arranged at the bottom of the second long rod. According to the draw-bar box auxiliary device capable of replacing the rolling wheels and protecting the hands, when the fixed block is separated from the machine shell, the left end of the fixed block drives the supporting rod to slide upwards, so that a movable contact on the surface of the supporting rod is in contact with a fixed contact, meanwhile, the right end of the fixed block drives a second push rod to slide downwards by extruding an electro-rheological body, the electro-rheological fluid solution becomes solid, the position of the second push rod is fixed, and the trend that the draw-bar box continues to incline is prevented, so that a protection effect is achieved.

Description

Technical field [0001] The present invention relates to the field of trolley case, in particular a trolley case assist device that can replace the roller and protect the hand. Background technique [0002] With the continuous development of socio-economic conditions, the trolley case has generally existed among people's daily life, can alleviate people's travel or the burden of the items with the office, so the features such as convenience and practicality are deeply affected by people.
