Description

Cargo box structure of Truck}

The present invention relates to a cargo moving device that can transport the loaded cargo in the cargo box of the lorry, in more detail, the loading compartment tail gate panel is capable of horizontal movement along the side gate panel, regardless of the moved position The present invention relates to a storage box structure capable of rotating, capable of loading a heavy cargo forward and safely transporting a cargo according to a change in the size of the storage box.

In general, various types of cargo are loaded into the cargo trays, which are classified into two types according to the type of cargo to be loaded, and are typically structured such as dump trucks and boxes mainly carrying irregular cargoes such as gravel or sand. There is a general van that carries mainly cargo.

The dump-type cargo is provided with a driving device such as a hydraulic cylinder at the bottom of the loading box, so that the cargo can be easily unloaded. However, the general cargo truck has a fixed loading box in which a driving device for loading or loading the cargo is removed. Is installed.

FIG. 1 is a perspective view illustrating a conventional loading box structure of a small freight vehicle, in which a side panel 2 and a tailgate panel 3 are hinged to a flat loading box bottom 1 as shown in the drawing.

Therefore, there is no choice but to rely on manpower to load or unload cargo without using a separate cargo transfer device such as a crane.

Therefore, not only waste of manpower and time can be wasted, but also when the heavy cargo is dragged out of the loading box, there is a risk of damage to the loading box and the lower end of the cargo. Cargo must be moved back to the front, if the heavy load has a problem that it is not easy to load sequentially from the front of the vehicle.

The present invention devised to solve the problems as described above is to enable the safe transport of cargo by reducing the length of the cargo compartment when the bulky and heavy cargo easily move in the cargo compartment, the amount of cargo is small.

In order to achieve the above object of the present invention, in the state in which the tail gate panel formed at the end of the loading box is opened, the loading container structure can be horizontally moved forward and backward, the length can be changed, and can be rotated at any point of the side gate panel. To provide.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the stacker structure according to an embodiment of the present invention.

FIG. 2 is a perspective view illustrating a stacker structure according to an embodiment of the present invention, FIG. 3 is a cross-sectional view illustrating a portion AA of FIG. 2, and FIG. 4 is a tail gate panel of the stacker structure according to an embodiment of the present invention. Is a perspective view showing a portion BB of FIG. 4.

As shown in the figure, the side gate panel 20 and the tail gate panel 30 are hinged at both ends and one end of the loading box formed at the rear of the vehicle body 10 to prevent the departure of cargo during operation of the vehicle. .

A plurality of first fastening holes 22 having a predetermined interval are formed at the upper side and the lower side of the side gate panel 20, and the moving rail 40 is mounted in the longitudinal direction in the mounting groove 24 formed at the lower end thereof. .

The moving rail 40 has a cross-sectional shape of a 'c' shape and a plurality of second fastening holes 42 are formed at regular intervals in the center thereof.

In the lower end side of the tail gate panel 30, a protruding lower roller assembly 80 inserted into the moving rail 40 is installed and moved along the side gate panel 20 to the front and rear of the loading box and in an open state at the upper end side. The upper roller assembly 70 is installed to facilitate separation and engagement.

The upper and lower roller assemblies 70 and 80 are inserted with a rotating shaft 84 having a bearing 88 mounted on the outside in a hole formed in the center of the roller 82 to facilitate smooth rotation. The rotating shaft 84 It is formed by fixing the inserted roller 82 to the fixing bracket 86.

A fixing lever 100 and a fixing lever support bracket 90 are mounted at upper and lower ends of the outer side of the tail gate panel 30, respectively, and the fixing lever 100 is disposed at a lower end of the tail gate panel 30. The third fastening hole 32 through which is formed is formed.

The tail gate panel 30 is 'Top plate 50 having a cross-sectional shape of a' 'Separated into a lower plate 60 having a cross-sectional shape of the' shape is coupled to change the length.
