Description

[Detailed Description of the Invention] The present invention relates to the structure of assembling a swivel for a truck bed.

Conventionally, in order to raise the loading platform of a luggage vehicle, the upper metal fitting of the hinge that connects the loading body and the loading platform is extended upward and brought into contact with the outer surface of the loading body, and a bolt with a semicircular head is connected to the upper metal fitting of the hinge that connects the loading platform. The structure is such that the fan body and hinge metal fitting are fastened together with a threaded nut, and when tightening bolts and nuts, the bolt head should be positioned inside the fan to avoid damage to the load. is common.

For this reason, in traditional agitation, Natsuto is placed outside the agitation (
It will stick out, which is both dangerous and unsightly.

The present invention was developed to eliminate the above-mentioned disadvantages.The nut does not protrude outward, so it is safe and looks good as it does not catch clothes etc. The lorry assembly of the truck bed provides a structure that avoids damage to the cargo.

Hereinafter, embodiments of the fanning structure of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the lift A of the truck platform is installed on the side edge of the platform 1 so that it can be raised and folded.

The fan main body 2 is constructed by combining a plurality of wooden boards, its outer surface is covered with a decorative board 21, and a plurality of outer reinforcements 3 are vertically arranged on the outer surface at predetermined intervals. It is set up.

As shown in FIGS. 2 to 4, the outer reinforcement 3 has a cylindrical shape with a flat hollow cross section, and a slit 31 is provided in the vertical direction in one plane part.

A plurality of T-nuts 4 are welded to the inside of the flat part so as to straddle the slits 31, and the outer reinforcement 3 has a decorative plate 2 on the flat side where the T-nuts 4 are provided.
It is in contact with 1.

The fan body 2 is provided with a through hole 22 at a position corresponding to the screw hole 41 of each T-nut 4 of the outer reinforcement 3 disposed as described above, and the decorative plate 21 is also provided with a through hole 22 at the same position. A through hole is provided.

On the inner surface of the fan body 2, an inner reinforcement 5, which has substantially the same shape as the outer reinforcement 3 and is slightly smaller, is vertically arranged at a position corresponding to the outer reinforcement 3.

A through hole 51 is provided in the flat surface of the inner reinforcement 5 on the loading platform side at a position corresponding to each of the through holes 21, and the circumference of the through hole 51 is bent to form a dish-shaped opening.

When assembling each member configured as described above, insert the bolts 6 from the loading platform side into the inner reinforcement 50 through holes 51. Each member is tightened by inserting it into the through hole 22 of the fan body 2, the through hole of the decorative plate 21, and the slit 31 of the outer reinforcement 3, and screwing it into the screw hole 41 of the tip 'kT nut 4 and tightening. Unify.

Among them, on the lower inner surface of each outer reinforcement 3,
The upper metal fitting 71 of the hinge 7 that connects the sight rail 11 of the loading platform 1 and the fan A is welded.

Of the through holes 51 of each inner reinforcement 5, the bolts 6 inserted into the through holes 21 of the fan body 2 from the lowermost through hole pass through the lower rail 8ak of the fan, and are screwed into the upper metal fitting 71. It is screwed into the hole and tightens the lower part of fan A and hinge 7.

The upper end of the outer IJ-7 forcement 3 is welded to the upper rail 8b.

As explained above with reference to the embodiments, the structure of the fan assembly of the present invention is to form a flat hollow cross section, provide a slit, and attach the reinforcement member fixed to the inside of the fan body to the outside of the fan body. Since the bolt is inserted from the inside and screwed into the nut, the nut and the tip of the bolt are hidden within the reinforcement, which prevents accidents due to contact, making it safe and aesthetically pleasing. It also looks good.

In addition, the head of the bolt does not protrude even inside the fan, making it possible to avoid damage to the load during loading and unloading during cargo transportation.

Claims (1)

[Scope of utility model registration request] It has a cylindrical shape with a flat hollow cross section, and has a longitudinal slint (1) approximately in the center of one plane part, and a reinforcement (k) with a nut fixed to it so as to straddle the slit on the hollow part side, and a reinforcement k that stretches the plane part with the slit. The fan body is arranged vertically in contact with the outer surface of the fan body, and a through hole is provided in the fan body at a position corresponding to the nut, and the bolt is inserted into the through hole and slit from the inner side of the fan body to tighten the nut. A structure for assembling a fan for a truck loading platform is characterized in that the reinforcement is screwed together to tighten the reinforcement and the fan main body.
