Abstract

The utility model relates to a closed box cover of a folding freight car, which is composed of slot-shaped tracks, rolling wheels, rolling wheel shafts, supporting shafts, connecting rods, hinge shafts, a folding sealing layer, chain ropes, chain wheels, a swinging link, a rocking handle, a locking hook rack, a front supporting shaft, a rear supporting shaft, a handle, a fixing plate and a fixing hoop, wherein, the outsides of the upper parts of the left side and the right side of a cargo box with an opening are provided with the slot-shaped tracks; the rolling wheels are installed in the slot-shaped tracks and are capable of leading the cargo box to slide and frontward and backward; the supporting shafts are installed on the rolling wheel shafts; the supporting shafts are connected with the hinged shafts through the connecting rods; the folding sealing layer is fixed on the supporting shafts and the hinge shafts; the supporting shafts are connected with the chain wheels through the chain ropes. Under the condition that the whole sealing layer is pulled flat to seal the opening of the cargo box, the supporting shafts on both end parts of the folding sealing layer are separately fixed with the front end of the cargo box and the chain ropes; the sealing layer can be pulled flat or folded by rocking the rocking bar so that the purposes of sealing or opening the opening of the cargo box can be achieved.

Description

Collapsible lorry sealing case lid

Affiliated technical field

The utility model relates to the upper shed of a kind of sealing lorry, the collapsible lorry sealing case lid that can upwards fold.

Background technology

At present, the sealing of known lorry upper shed is to adopt canvas or hydraulic pressure opening hardcoat, need manually get on the bus with the canvas sealing, has dangerous and shortcoming such as bad sealing; The hydraulic pressure opening hardcoat has the manufacturing cost height, opens and closes shortcomings such as easy clashing and breaking.

Summary of the invention

For shortcomings such as the top cover bad sealing that overcomes existing lorry or manufacturing cost height, the utility model provides a kind of collapsible lorry sealing case lid, and this case lid is easy to use, be difficult for clashing and breaking.

The technical scheme that its technical matters that solves the utility model adopts is: the outside vertical installation grooved track in top, the upper shed container left and right sides, roller is installed in the grooved track and makes it scroll forward and backward, pivot shaft is installed on the roller shaft, brace rod is connected pivot shaft with hinge axis, collapsible sealing layer is bound up on pivot shaft and the hinge axis, the chain rope is connected pivot shaft with sprocket wheel, even up under the sealing container situation suitable for reading at whole collapsible sealing layers, collapsible sealing layer both ends pivot shaft is fixed with compartment front end and chain rope respectively, rotate bull stick and make collapsible sealing layer even up or fold, to reach sealing or to open container purpose suitable for reading.

The beneficial effects of the utility model are, the upper shed platform cover is opened convenient, reduce clashing and breaking, seal tightly, and cost is low, and is simple in structure.
