The present invention is related to the loading capacity of the cargo box, which automatically opens and closes the loading box cover, and in particular, it prevents overloading of trucks and prevents damage to roads and bridges and prevents accidents caused by overload. It also has strong structural advantages against external shocks.

Conventionally, as in the present invention, the structure of the cargo box is improved, and the height is fixed without the structure of the Kabatan Jibong (300, 400, 500), which is assembled and laid down and unfolded. Kabatan jibong of the form gathered on one side and the structure is expanded in the opposite direction or the pipe or round rod mounted to the upper side of the body frame 200 of the stacking box 100, and then hang the loops at both ends of the length of the loading box cover and the rings There is a structure in which the loading box cover that floats in the air while acting as a bushing is gathered forward and gathered back and unfolds again, and the cover plate which is hinged and folded on the loading box 100 is connected. Is not very practical due to the high rate of failure due to the high complexity of the parts and the incidence of breakdowns.They have two or three steps in operation, which is inconvenient.In particular, it is inconvenient to use gravel, stone, sand If the fork lane's bucket is hit when loading the car, There was a problem that the teeth were damaged, so it was not possible to obtain advantages in use, and when the soil, sand, gravel, etc. were caught in the device, the operation became difficult or the parts were broken, so the durability of the device was poorly confused. .

In addition, the conventional device has a complicated structure and a lot of difficulties in the installation, so the problem that the equipment cost is very high cannot be ignored.

Accordingly, the present invention is described in detail by the accompanying drawings as a configuration devised to provide a new loading capacity of the cargo box is automatically opened and closed the cover box cover to solve the shortcomings and problems of the conventional apparatus described above.

In front of the loading box 100, the reduction motor 17 is placed in the center, and on the left and right sides thereof, the winch drum 20 having the screw 27 formed on the extended shaft is fixed by each chain. A chain is attached to the gears 18, 19, and 22 to drive and drive the power, and the moving plate 28 is screwed into the extension shaft screw 27 of the winch drum 20 described above, By installing the stoppers 25 and 23 with the limit switches 26 and 24, the limit switch 26 and 24 are moved while the moving plate 28 moves up and down as the winch drum 20 rotates forward and backward. Interfering with the power to cut off the power supply to form the driving unit,

After attaching the reinforcement frame 1 having the cutout portion 2 formed to the outside on both sides of the body frame 200, and speaking inside the rail rod 4 supported by the lower support 3, The guides 7 of the shifters 5, 5a and 5b each having guides 7 supported by the braces 6 are assembled in sequence so as to be inserted into the rail rods 4, but the rearmost Attach the wire connector 9 to the iron 5b so as to bind both ends of the wire 8 returned to the winch drum 20 so that both ends of the wire 8 are firmly fixed as the wire anchor 10, and the vehicle body After the two sieves 16 are installed in the front left of the frame 200, the screw rod 13 having the hexagonal head 15 is provided by the support 14 in the rear inner side of the reinforcement frame 1. While supporting, pull the pull 12 and assembling the sheave 11 to the pull 12 so that the wire 8 returned to the winch drum 20 supports the front sheave 16. B. As the winch drum 20 is operated by the driving unit by passing through the sieve 11 at the rear side, the rear shifter 5b on which the wire 8 is bound rides on the rail rod 4. As the left and right shifting levers 5 and 5a move left and right as they move to the left and right, the rear shifting lever 5b pushes the other shifting levers 5 and 5a when they are gathered to the left and moves when they are unfolded to the right. As the iron 5b moves to the right, the shifter 5 is pulled by the freight carbatan support rods 300 and 400 assembled to each shifter 5, 5a and 5b and connected to each other. The present invention is characterized in that the cargo carbatan support rods 300, 400, and 500 are folded so as to be pulled and unfolded (5a).

When the deceleration motor 17 is operated, the winch drum 20 is rotated, and the upper part of the wire 8 returned to it is released and the lower part is wound.

Accordingly, the shifting rod 5b having the both ends of the wire 8 bound to the right moves in the state of FIG. 1, but is smoothly moved on the rail rod 4.

When the shifter 5b moves to some extent, the cargo carbane support rods 300 and 400 are extended to the right, and the other two shifters 5a and 5 are naturally pulled to move to the right.

At this time, the moving plate 28 is gradually moved upward by taking the screw 27 formed on the extension shaft of the winch drum 20, and the moving plate 5 when the moving bars 5, 5a and 5b are properly unfolded. ) Interrupts the upper limit switch 26 to cut off the power of the reduction motor 17 and the operation of the device is stopped so that the cargo cover tank rods 300, 400 and 500 are well shown. Unfold and cover the cargo to achieve the desired bar.

Next, take off the cargo cover to get off the cargo, and when the deceleration motor (17) is to be reversed, the operation of the device is moved to the left by the reverse mechanism 5b by the opposite way to the unfolding.

At this time, the remaining shifting levers 5 and 5a remain until the shifting lever 5b moves to the left and pushes them, and then the shifting lever 5b moves to the left in order from the start of the push, eventually moving as shown in FIG. All are gathered to the far left and accordingly, the cargo cover is 300, 400, and 500 are also folded to the left, so the cargo cover is peeled off. It is economical, convenient, powerful and safe with no balance, simple installation and easy maintenance.

The present invention, which operates with the structure as described above, is a rail-type structure that is robust and not complicated, so there is no failure, the installation cost is low, and there is little risk of parts being broken, and there is no noise using the winch drum 20. It has the advantage of being operated as fast, accurate and powerful power.

In addition, by making the protrusions of the cargo carbatan support rods 300 and 400 slightly higher than the height of the loading box 100, the effect of preventing overload can be achieved, and the contents of the contents are well protected by utilizing the strong structural features. It has the effect of preventing lungs from falling or flying.

The present invention is cheaper than conventional loading box cover automatic switchgear, has no trouble, and is strong, so it is very durable, beautiful in appearance, strong in impact, and prevents foreign substances from getting caught in devices or accessories. It has a number of useful new effects, such as to extend the operation and to obtain a smooth operation effect to maximize the work efficiency.
