Description

A hook structure in truck's carrying room}

The present invention relates to a hook structure of a truck loading box, in particular, in a hook structure installed inside the truck loading box, the hook is installed on the truck loading box using a rotating shaft so as not to be exposed to the outside when not in use. It relates to a hook structure of a truck loading box to be exposed to the outside.

Cargo truck loading boxes are designed to hold a large amount of cargo, so when loading cargo below the height of the side gates and tail gates of the cargo box, ropes are not normally used, but the height of the side gates and tail gates In the case of high cargo loading, ropes are used to support the cargo in the cargo box.

At this time, in order to ensure the fixing of the rope hook-shaped hook is installed on the side gate and tail gate. In addition, depending on the size of the cargo, a hook for fixing a rope may be conveniently installed inside the side gate and the tail gate, depending on the size of the cargo. As shown in FIG. 1A, the side gate 1 and A hook 4 is provided on the inner side of the tail gate 5.

FIG. 1B is a detailed view of the portion a of FIG. 1A, showing that one end of the hook 4 formed in the shape of a ring is provided close to the reinforcing bar 2 of the side gate 1. At this time, the hook 4 is fixed to the lower frame 3 by a welding method.

In the case of the hook structure described above, there is no problem when the hook 4 is used, but when the hook is not used, the cargo loaded by the hook 4 exposed to the outside is damaged.

In addition, since the hook 4 is fixed by the welding method, corrosion occurs at the welded part, and the corrosive material is deposited on the surface of the loaded cargo, and when the welding is not performed properly, the hook is separated from the lower frame. There was this.

The present invention was devised to solve the above problems, the hook is installed on the inside of the truck loading box when the hook is not used is built into the reinforcement and exposed to the outside when used and the angle of the hook according to the use state It is an object of the present invention to provide a hook structure of a truck loading box so that is changed.

Figure 2 is an exploded perspective view showing the configuration of an embodiment of the hook structure of the truck loading box according to the present invention, in the truck loading compartment divided into the side gate and the tail gate, through holes 16 are formed on both sides, respectively, First and second fixing pins 20 and 30 inserted into the side gate reinforcement 10 having the opening hole 14 formed therein, and inserted into the through holes 16 of the side gate reinforcement 10, respectively. The part is formed in a ring shape and the other end is shown to be composed of a hook 40 formed in the form of a rotating shaft so that the first and second fixing pins (20, 30) can be inserted.

End portions of the first and second fixing pins 20 and 30 which are coupled to each other, the ends of the first and second fixing pins 20 and 30 are formed in the form of bolts and nuts, respectively, and the first ends of the first and second fixing pins 20 and 30 are formed at the other ends thereof. And the locking end (22, 32) is preferably formed so that the second fixing pins (20, 30) are coupled to each other so as not to be separated.

In addition, after the first and second fixing pins 20 and 30 are coupled, the return spring 50 may be additionally installed on the outer circumferential surface, so that when the hook 40 is not used, the inner side of the side gate reinforcement 10 is provided. It is desirable to be built into.

When explaining the embodiment of the present invention configured as described above with reference to the drawings as follows.

Opening holes 14 are formed in the vertical direction on the front surface of the reinforcing bar 10 of the side gate constituting the truck loading box, and through holes 16 are formed at the same height on both lower sides of the reinforcing bar 10, respectively. It is. After the hook 40 is positioned inside the reinforcing rod 10, the first and second fixing pins 20 and 30 are inserted through the through holes 16 on both sides, and the inserted first and second fixing pins ( 20 and 30 are in contact with both ends of the first and second fixing pins (20, 30) through the rotating shaft formed on one end of the hook (40), and rotates each of the fixing pins in the form of bolts and screws The formed first and second fixing pins 20 and 30 are coupled to each other.

When the first and second fixing pins 20 and 30 are coupled to each other, the return spring 50 is installed on the outer circumferential surface of the fixing pins. One end of the return spring 50 is fixed to the first fixing pin 20 or the second fixing pin 30 side and the other end is fixed to the hook 40 so that when no external force is applied to the hook 40 It is preferable that the hook 40 is configured to move inside the reinforcing bar 10.

After loading the cargo into the truck's loading box, the cargo is fixed by using a rope to prevent the cargo from falling due to the vibration generated during the driving of the vehicle. In this case, in order to facilitate the fixing operation using the rope, a hook installed on the side gate and the tail gate of the loading box is used.

To use the hook according to the present invention in the following order.

While not using the hook 40, the hook 40 is positioned inside the side gate reinforcement 10 by the elastic force of the return spring 50. In order to proceed with the fixing operation using the rope after loading the cargo in the stacker, the hook 40 is pulled by a worker's manual work, so that the hook 40 is positioned in the A portion as shown in FIG. 3.

The hook 40 pulled by the operator is exposed to the outside through the opening hole 14 of the side gate reinforcement 10. At this time, the operator to hang the rope on the hook portion of the exposed hook 40. When the hook is hooked to the hook 40, the angle of the hook 40 may be changed according to the height of the cargo loaded in the loading box.

In order for the truck to arrive at the destination and unload the loaded cargo, the rope hanging on the hook 40 is removed. The hook 40 from which the rope is removed is built into the position B of FIG. 3, that is, the inner side of the side gate reinforcement 10 by the elastic force of the return spring 50, so that the rope 40 is not visible from the outside.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to these embodiments, and has been claimed by those of ordinary skill in the art to which the invention pertains. It includes all the various forms of embodiments that can be carried out without departing from the spirit.

According to the present invention configured as described above, when fixing the cargo in the truck loading box using a rope, the cargo fixed operation is exposed to the outside can be used, but when not in use so as not to be exposed inside It has the effect of enhancing the aesthetics and enhancing the safety of use.

Figure 1a is a perspective view showing the shape of the truck loading box according to the prior art.

1B is a detailed view of the portion a in FIG. 1A.
