Description
Technical field
The utility model relates to a kind of draw-bar box, and hard draw-bar box is strengthened on especially a kind of surface.
Background technology
Draw-bar box is as the important tool of people's go off daily, and application widely.Existing draw-bar box is usually more dull in structural design; There is very large defect in much soft draw-bar box, especially in the process of long-distance travel, be easy to owing to raining, collision and extruding etc. cause article in case to damage in resistance to compression, shock-resistant, waterproof and protectiveness.There is the defects such as weight is large in the hard draw-bar box of existing PVC.
Summary of the invention
The purpose of this utility model is to provide a kind of novel in structural design, the good and hard draw-bar box of carrying convenience of crushing resistance, resistance to impact, water proofing property and practicality.
What the utility model solved is that the structural design that existing draw-bar box exists is dull, and resistance to compression, shock-resistant, waterproof and protectiveness are poor, and the defect of heaviness is carried in trip.
The technical scheme that the utility model technical solution problem adopts is: hard draw-bar box is strengthened on a kind of surface, comprises pull bar, case lid and casing, and described case lid is connected with casing by case lid slide fastener; Described case lid surface is provided with concave inward structure, and described concave inward structure comprises concave inward structure, left concave inward structure and right concave inward structure; Described upper concave inward structure is positioned at the middle and upper part of case lid, in " convex " font; Described left concave inward structure is positioned at the left side of case lid, and in " river " font, described right concave inward structure is positioned at the right side of case lid, and in " river " font, described left and right concave inward structure is symmetrical; Four feets are provided with on the right side of described casing; Four rollers are provided with bottom described draw-bar box; Described casing top intermediate lateral is provided with carrying handle, and carrying handle rear is provided with pull bar, is provided with button in the middle part of pull bar handle.The case lid of described draw-bar box and casing adopt ABS material, have good resistance to compression, shock-resistant, water resistance, and lighter in weight, facilitates trip to carry simultaneously.
Preferably, described carrying handle two ends are equipped with fixed block, and carrying handle firmly can be fixed on casing, when avoiding beginning a new line weight, carrying handle comes off, and impact uses.
Preferably, described feet is elliptical cylinder-shape, and for being arranged above and below between two, when draw-bar box side direction is placed, cylindroid cross section and earth surface, place more steady, safety.
Preferably, described roller and draw-bar box junction are provided with cornerite, roller are combined more firm with draw-bar box; Described roller is universal wheel, convenient and strength-saving when towing.
Preferably, described case lid slide fastener is two-way separating zip, is convenient to article and picks and places.
The beneficial effects of the utility model are: hard draw-bar box provided by the utility model, owing to having concave inward structure in surface design, make case lid surface spatially structure, improve the intensity of case lid, be conducive to the resistance to compression of draw-bar box and shock-resistant, this structure is comparing with the hard draw-bar box of same intensity, and weight is lighter, is convenient to trip and carries.
