Description

A cover structure for loacding box of truck}

The present invention relates to a structure of a cover for a truck loading box, and more particularly, to a structure of a cover for a truck loading box to facilitate replacement of the cover frame.

Conventionally, as shown in FIG. 1, the first cover part and the second cover part are configured, and the second cover part is folded by a folding means, and a coil is formed on the lower cover frame 21 of the second cover part 20. The spring 40 is mounted to be wound, and one bent portion 41 of the coil spring 40 is hung on the support 22 of the second cover portion 20, and the other bent portion 42 is formed on the first portion of the coil spring 40. The cover 1 can be folded by being caught by the bar 12 of the cover 10 so that the second cover 20 is pulled inward by the elastic force of the coil spring 4.

The cover frame is a portion covered with a cloth for covering the loading box, and in the case of a two-stage folding type cover, two cover frames are provided. However, since the cover frame of the second cover part located on the upper part of the cover frame is exposed to the outside of the vehicle, there is a great disadvantage of damage due to the rough working characteristics of the trucks carrying aggregates or rocks.

However, the cover frame 21 of the second cover portion 20 is directly coupled to the second cover folding means 30, as shown in Figure 1, the coil spring 40 is also attached to the cover frame 21 Since the structure that is directly coupled to the carburizing action, if the second cover portion 20 is broken, it will have a closed end that eventually needs to replace the entire cover 1.

Thus, the conventional cover is the first cover part and the second cover part is integrally combined, so even if only the second cover part is repaired, the entire cover must be removed once, and after the second cover part is repaired, it is combined with the first cover part again. It is very unreasonable not only for the operator but also for the vehicle owner, because it takes a lot of time and effort to repair the cover.

The present invention is designed to improve the disadvantages of the lid for the conventional truck loading box is coupled to rotate by the drive shaft, the shaft formed on the end of the bar, and coupled to the shaft rotatably coupled to the cover folding means A second cover frame including a rotating hole connected to the connecting hole and a through hole coupled to one end of the rotating hole, and having a cover frame formed in one piece by means of fastening means. It is to provide a cover for a truck loading box that can be easily separated and combined from the cover.

A: Cargo Carrier

Referring to the configuration of the subject innovation in detail as follows.

The present invention is composed of a first cover portion and a second cover portion, the second cover portion in the cover for the truck load is folded in two stages by the cover folding means in the drive shaft 800 for driving the cover 100 Combined bar 700, the shaft 710 formed at the end of the bar, the coil spring 500 to be fitted to the shaft to act on the bar 600, 700 and rotatable to the shaft 710 A bar 600 having a rotating hole 720 coupled to one end thereof and connected to the cover folding means 200, and a through hole 411 coupled to one end of the rotating hole, and a fastening means 900 at the bar. It is composed of a cover frame 410 formed integrally detachable by.

The coil spring 500 is applied to the elastic force so that the bar 600 and the bar 700 can be folded inward with respect to the shaft 710.

In the present invention, a bolt 910 and a nut 920 are formed on one side of the cover frame 410 by punching the through hole 411 at a position facing the through hole 610 of the bar 600. It is preferable to be coupled by the same fastening means 900, but the method of coupling the cover frame 410 to the bar 600 by direct welding will also be included in the scope of the claims of the present invention.

In addition, the nut 920 is preferably used to prevent the loosening nut is configured to tighten as the vibration is applied in the characteristics of the present invention utilized in the rough work.

Effects of the present invention as described above are as follows.

That is, the configuration of the second cover portion 400 in the present invention cover 100 is composed of a bar 600 and the cover frame 410, the cover frame 410 of the second cover portion 400 is a conventional cover Like the cover frame 21 of (1) is not integrally formed to be separated from the first cover portion, it is to be freely separated from the bar 600 supporting the cover frame 410.

This is of course the cover frame 410 of the present invention is not formed integrally with the first cover portion 300, but is manufactured in an independent state to be detachable at any time from the bar 600 supporting the cover frame 410 at any time It will be possible to remove and install.

Due to this, the present invention cover 100 is the most frequently damaged second cover portion 400 is easy to install and detach easily by the fastening means 900, so repair and replacement can be made quickly, the second Since the work can be performed without removing the cover from the first cover, the difficulty of the work is also significantly reduced.

In addition, the present invention is possible to remove the second cover portion only by the fastening means, so that the cover and the second cover portion can be repaired and replaced even when attached to the loading box of the truck.

As such, the present invention has a structure in which the cover frame of the second cover part is detachable from the immediate state, and thus the structure of the second cover part is easy to repair and replace, which is the most frequently damaged part of the cover of the present invention. After the repair, the second cover part is no longer required to be coupled to the first cover part, etc., thereby making it possible to perform a quick and easy operation, thereby facilitating the convenience and benefit of both the operator and the driver.

In addition, the present invention had to work after removing the entire cover from the vehicle unconditionally, even if only a part of the cover, such as the conventional cover, the present invention can also remove the second cover by the fastening means, and the cover is also loaded in the truck It is a very useful design that can be repaired and replaced only the second cover part even when attached to the.
