Description

Carrying box door for truck with rope connector and door hinge

The present invention relates to an aluminum-integrated vehicle loading box door provided with a rope hanger and a hinge, and more particularly, provided by extrusion molding the vehicle loading box door in an aluminum-integrated type, but having a rope hanger and a hinge provided so that the luggage is loaded and then tied with a rope. The present invention relates to an aluminum-integrated vehicle loading box door provided with a rope hanger and a hinge, which enables it to be securely tied and to facilitate hinge connection with the vehicle loading box.

In general, the loading box of a truck, such as a truck, is provided at the rear of the truck, and by installing a loading box door that can be opened and closed on both sides and the rear of the loading box, the cargo can be easily accessed when loading and unloading various cargoes.

The loading box of such a truck is in a state where the upper part of the loading box is opened except for vehicles for special purposes such as refrigeration vehicles, and a separate cover device is additionally installed to protect the cargo loaded in the loading box.

The loading box door of such a freight car is made of steel, but it is manufactured by combining a number of parts by press forming, bending and welding, and it is mounted integrally with the loading box and painted and then the outer plate is painted and heat treated in a specific color. It is commercially available.

However, there is a problem in that the loading box of a truck made of a conventional steel material is frequently exchanged due to deterioration in appearance quality and reduction in durability, and accordingly, the operating cost is increased.

Looking at the prior art, a door structure of a commercial vehicle loading box, which is No. 20-1997-0001981 for public office, has been devised, which is welded to the floor and has a set member having a hinge bracket at a predetermined position, and a hinge pin inserted into the hinge bracket. In the door structure of a loading box for a commercial vehicle consisting of a loading box door panel equipped with a reinforcing bead and a stiffener on the inner side and provided with a hinge to be rotatable through the medium, the inner surface of the loading box door panel provided with the bead and the stiffener A plastic molded product in a roughly U shape to wrap the upper part of the brim and the outer side of the brim is fixed to the loading box door panel through a plurality of fixing means.

This prior art is to obtain the effect of preventing rust inside the door and alleviating damage to cargo impact by means of a plastic molding attached to the loading box door panel via a fixing means, but it is used for a long time because the loading box door panel is made by welding a steel plate. In the case of rust, there is a problem in that productivity decreases due to corrosion or complexity of assembly work.

In addition, a structure of a loading box door for a freight vehicle, which is registered patent No. 10-1705282, has been devised, and this is a structure of a loading box door that is vertically erected and rotatably installed on both sides and rear of the bottom of the top open loading box of the freight vehicle, An inner plate portion having a predetermined cross-sectional thickness and extending by a predetermined height from the inside of the loading box door, an upper frame portion formed at an upper end of the inner plate portion to form an upper support of the loading box door, and a lower end spaced apart from the inner plate portion by a predetermined width The inner plate portion and the outer plate portion that is continuously connected to the inner plate portion and extends by a predetermined height from the outside of the loading box door, and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the inner plate portion and the A plurality of reinforcing ribs connecting the outer plate portions are extruded out of aluminum to form an integral door frame.

This conventional technology is extruded from aluminum to make the door frame as an integral body, thereby greatly improving moldability and corrosion resistance, reducing the number of parts and assembling man-hours, resulting in cost reduction, as well as lightening the vehicle's fuel economy. I'm looking forward to it.

However, in the case of the prior art, a hinge connector connected to the hinge of a freight vehicle is provided by welding on the inner surface of the extension part integrally provided with the door frame, and a rope that hangs a rope to bind the loaded cargo after loading the cargo. As the ring is provided on the inner surface of the curved portion integrally provided with the door frame by welding, there is a problem in that the hinge connector and the rope ring fall when used for a long period of time.

In other words, the rope ring connected to the inner surface of the curved part by welding is connected to the inner surface of the curved part by welding as the pulling force is repeatedly applied to the rope ring in the process of strongly pulling the rope by hooking the loaded cargo. There is a problem that the rope ring falls off.
