Durable draw-bar box

Abstract

The invention discloses a durable draw-bar box, which comprises a box body and rollers. The rollers are rotatably connected to the left side and the right sides of the bottom end of the box body, inserting grooves are formed in the left side and the right sides in the box body, inserting rods bars are inserted into the inserting grooves, horizontal barsrods are fixedly connected to the upper endsand the lower ends of the inner walls of the inserting barsrods, sliding barrods sleeve the outer walls of the horizontal barrods, and clamping blocks are fixedly connected to the bottom ends of the right sides of the sliding barrods. According to the durable draw-bar box, a button, a pressing plate and first springs are matched to enable the sliding barrods to be quickly opened, the inserting barrods can be quickly pulled out of the box body, through cooperation between the sliding barrods, the horizontal barrods and the clamping blocks, the inserting bar rods can be quickly clamped and meanwhile the heights of the inserting barrods can be adjusted, the inserting barrods can be more stable and be prevented from shaking when pulled out of the box body, the heights of the inserting barrodscan be adjusted according to users with different body heights, using is simple, and the service life of the draw-bar box can be prolonged.

Description

technical field [0001] The invention relates to the technical field of durable trolley cases, in particular to a durable trolley case.

It is widely used because of its convenient use. At the same time, the trolley case is also equipped with a trolley, which can be divided into single-tube trolley and double-tube trolley. Greatly reduce the burden, the trolley case can be carried or dragged, the wheels of the trolley case we usually use are basically located at the bottom of the case, and modern people have designed a new form of trolley case, which is designed as a cylinder The shape and the wheels are completely outsourced on the outside of the box. This roller design makes this trolley box better adapt to different terrains. For example, you can easily go up and down the stairs by directly pulling the box. The trolley of the existing trolley box is very easy to damage. , the button of the trolley has a short service life, and the trolley of the trolley case shakes, which makes the trolley case extremely undurable
