Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement in a method for attaching an engagement fitting of a locking hook member to a tilt plate of a truck bed.

(Prior Art) Conventionally, as a means for attaching the engagement fitting of the locking hook member on one of the tilt plates of a truck bed to the other tilt plate, a plurality of insertion holes are formed through the tilt plate at required locations. On the other hand, an engaging recess for the locking hook member of the gate plate is provided at one end, and the engagement fitting of the hook member, which has an insertion hole penetrated at a position corresponding to each of the insertion holes, is inserted into the outer surface of the gate plate. A method is adopted in which the engagement fittings are directly fastened to the gate plate by inserting and fastening blind rivets into each of the insertion holes so that the respective insertion holes are aligned with each other.

(Problem to be Solved by the Invention) However, the tilt plate of the truck bed is made of a lightweight metal plate such as aluminum in order to facilitate the lifting and lowering rotation operation that is frequently performed each time the cylinder is raised and lowered. Although it is excellent in lightness, it is insufficient in strength such as load resistance and bending resistance. Therefore, due to the load and impact of the loaded material applied to the above-mentioned engagement fittings, the gate plate is likely to swell and deform from the hole edge of the insertion hole of the blind rivet that fastens the engagement fittings, or to be easily torn or damaged. While the truck is running, the alloy tool unexpectedly detaches from the swing plate and becomes unlocked from the hook member attached to the other swing plate, causing the swing plate to droop and release the loaded cylindrical material onto the road. There were serious problems such as the occurrence of dangerous accidents.

The present invention was developed with the aim of solving the above-mentioned problems, and provides a method for strongly attaching the engagement fitting of the locking hook member to the tilt plate of a truck bed by a simple means. The purpose is to provide.

(Means for Solving the Problems) As a means for solving the above problems, in the present invention, reinforcing metal plates are bonded to required locations on the inner surface of the tilt plate, and the bonding positions of the reinforcing metal plates are matched to the bonding positions of the reinforcing metal plates. When the locking hook member of the tilting plate is in contact with the outer surface of the tilting plate, the engaging fitting is integrally fastened to the tilting plate together with the reinforcing metal plate using a fastening member such as a blind rivet. This method adopts a method for attaching an engaging fitting for a locking hook member on a truck bed tilt plate, which is characterized by the following: More specifically, reinforcing metal plates are bonded to required locations on the inner surface of the tilt plate. a step of penetrating the reinforcing metal plate and the tilting plate at multiple locations with common insertion holes;
An engagement recess for the locking hook member of the tilting plate is provided at one end, and the engaging fitting of the hook member, which has an insertion hole penetrated at a position corresponding to each of the above-mentioned insertion holes, is brought into contact with the outer surface of the tilting plate. A truck bed tilting system comprising the steps of aligning the insertion holes, and inserting and fastening blind rivets into each of the through holes to integrally fasten the engaging fittings to the tilting plate together with a reinforcing metal plate. This method adopts a method of attaching an engaging fitting of a locking hook member to a plate.

(Function) According to the above-mentioned method of attaching the engagement fitting of the locking hook member to the truck bed swing plate according to the present invention,
The gate plate where the engaging metal fittings are attached is reinforced with a reinforcing metal plate, so even if the gate plate is made of a lightweight metal plate with relatively low hardness, such as aluminum, it will not be difficult to tighten the locking metal fittings. This has the effect of preventing the gate plate from expanding, deforming, or tearing from the edge of the blind rivet insertion hole. Therefore, while the truck is running, the engagement tool unexpectedly detaches from the swing plate and becomes unlocked from the hook member attached to the other swing plate, causing the swing plate to unexpectedly fall down and cause the cylinders loaded on the loading platform to be removed. This has the effect of preventing the occurrence of dangerous accidents where materials are released.

Furthermore, the above-mentioned effects can be reliably achieved by adding one simple step, which is simply bonding the reinforcing metal plate to the flap plate, compared to the steps of the conventional method.

(Embodiment) Below, embodiments of the present invention will be described based on the attached drawings. As shown in the figure, reinforcing metal plates 2 made of steel are bonded to required locations on the inner surface of the tilting plate with a strong adhesive, and are also bonded under strong pressure to the inner surface of the tilting plate 1 using Yatco.

Next, as shown in FIG. 2, common insertion holes 3 are drilled at multiple locations in the tilting plate 1 and the reinforcing metal plate 2 using a drill D, and then, as shown in FIGS. An engagement recess 4 for a locking hook member (not shown) for the tilt plate is provided on the side edge of the
At the same time, the steel engagement fittings 6 of the hook member, which have insertion holes 5 through them at positions corresponding to the insertion holes 3 of the tilting plate 1 and the reinforcing metal plate 2, must be brought into contact with the outer surface of the plate 1. The insertion holes 3 and 5 are brought into contact with each other and aligned. Next, a plurality of (two in this embodiment) blind rivets 7.7 are inserted into each of the matched insertion holes 3.5 from the engaging metal tool 6 side, and each blind rivet 7.7 is inserted using a blind rivet (not shown). By fastening the blind rivets 7.7, the engaging metal fittings 6 and the reinforcing metal plate 2 are integrally fastened to the outer surface of the plate 1, as shown in FIG.

Therefore, the engaging metal fitting 6 attached to the tilting plate 1 of the truck bed as described above has a structure in which the hinged plate 1 is lined and reinforced with the reinforcing metal plate 2 at the attachment point. When the locking hook member (not shown) of the flap plate 1 is engaged with the engagement recess 4 of the alloy tool 6, the load and impact of the cylindrical material loaded on the truck bed are applied to the flap plate 1. Therefore, even if the load and impact are applied to the engaging metal fittings 6, the tilting plate 1 may swell and deform from the hole edge of the insertion hole 3.3 of the blind force bed 7.7, or be torn and damaged. It is possible to effectively prevent the engagement fitting 6 from unexpectedly detaching from the plate 1.

(Effects of the Invention) As is clear from the above description, according to the method for attaching the engaging fitting of the locking hook member to the swinging plate of a truck bed according to the present invention, it is possible to attach the locking hook member to the swinging plate at the attachment point of the engaging fitting. The mechanical and physical strength of the steering wheel can be significantly improved, so that if the engaging tool accidentally detaches from the steering wheel while the truck is running, it will not be able to engage with the hook member attached to the other steering wheel (the steering wheel It is possible to reliably prevent the occurrence of serious dangerous accidents such as when the lock state of the vehicle is released and the gate plate is fenced off, causing cargo etc. to be released onto the road.

In addition, since the reinforcing metal plate is only used in a very limited area of the tilt plate, it is possible to reduce the weight of the tilt plate, which is required in order to maintain ease of lifting and rotation operations that are frequently performed. There is no damage in the slightest, and the method for attaching the engagement fittings is simple and easy, and there are advantages in that it can be implemented economically and at low cost.
