Pre-tightening assembly for preventing goods from overturning in large luggage

Abstract

The invention relates to the technical field of luggage storage, and discloses a pre-tightening assembly for preventing articles from overturning in a large luggage, the pre-tightening assembly comprises a shell, a slide rail is arranged on the left side in the shell, a movable ball is movably inserted in the slide rail, the lower end of the movable ball is fixedly connected with a support spring, and the right end of the movable ball is fixedly connected with a bottom plate, a support is fixedly connected to the front end of the bottom plate, and a pre-tightening spring is movably inserted into the support. By rotating a rotating rod, the rotating rod drives a piston to move downwards along the interior of a liquid storage tank under the action of tangential force of threads between the rotating rod and a shell, so that water liquid in the liquid storage tank enters a guide rod, the water liquid pushes a driving rod to compress a reset spring to move downwards, and the driving rod drives a push plate to move leftwards through a connecting rod; and goods in the shell are fixed, so that the effects that the goods can be pre-tightened conveniently and rapidly, and damage caused by shaking in the walking process is avoided are achieved.
