Description

  The present invention relates to a panel assembling type rear car that is assembled by connecting means such as bolts without welding an aluminum panel.

  In a conventional rear car, a skeleton frame is formed by welding means in order to constitute a rear car bed, and a rear car bed is manufactured by welding a panel to the frame.

JP 2018-143458 A

  However, since the conventional rear car forms a skeleton frame by welding, it takes time to manufacture, and if aluminum material is used for weight reduction, welding of aluminum material is difficult compared to iron material, and it is difficult to do The problem was that welding was required. In addition, since the welded portion has weld fatigue, there is a problem that the strength is remarkably deteriorated when used for a long time. Furthermore, fixing by welding makes it difficult to replace parts, and eventually increases the cost of the product.

  The present invention provides a panel-assembled rear car that solves the problems of the prior art, has a small number of parts, has no fixed parts by welding, is easy to assemble, is lightweight, durable, and can be easily replaced. Objective.

  In order to solve the above problems, the panel-assembled rear car of the present invention has a floor plate in which a reinforcing member is fixed to a lower surface with screws, and a wheel cover whose side is covered with a reinforcing frame and side cover members in a central portion is fixed with screws. 5 loading platform components consisting of left and right side plates, a rear plate, and a front plate with a traction handle fixing member fixed to the front by bolts, and a connecting portion having bolt insertion holes at the ends of the adjacent loading platform configuration members A loading platform formed by fixing the loading platform component adjacent to the connecting portion with bolts, an axle fixed between the left and right side plates and the side cover member, and a wheel rotatably supported on the axle, A traction handle fixed to a traction handle fixing member fixed to the front plate, and a grounding leg fixed to the front side of the loading platform to which the traction handle is fixed.

  The panel-assembled rear car of the present invention is characterized in that L-shaped reinforcing members are fixed to the upper four corners of the loading platform.

  In the panel assembly type rear car of the present invention, the floor plate, the left and right side plates, the rear plate, and the front plate are made of aluminum, and the reinforcing plate fixed to a part of the side cover member that passes through the reinforcing frame and the axle is made of stainless steel. It is characterized by that.

  The panel-assembled rear car according to the present invention includes an opening / closing lid that is hinged to one side plate upper portion of the left and right side plates.

Floor plate with reinforcement frame fixed with bolts and nuts on the bottom, left and right side plates with wheel cover with reinforcement frame and side cover covered with side cover members at the center, rear plate, and traction handle fixed on the front Forming a connecting portion having a connecting bolt insertion hole at the end of an adjacent loading platform constituting member, and forming the connecting loading plate constituting member adjacent to the connecting portion with bolts. It is fixed to a loading platform formed by fixing, an axle fixed between the left and right side plates and the side cover member, a wheel rotatably supported on the axle, and a traction handle fixing member fixed to the front plate. By having a tow handle and a grounding leg that is fixed to the front side of the loading platform to which the tow handle is fixed, the number of parts is small, there is no fixed part by welding, and it is easy to assemble, is lightweight, durable, and replaces parts. It is possible to provide an easy panel prefabricated Carts.
By fixing the L-shaped reinforcing members to the upper four corners of the loading platform, the strength of the loading platform can be improved.
The floor plate, left and right side plates, rear plate, and front plate are made of aluminum, and the reinforcement plate fixed to a part of the side cover member that inserts the reinforcement frame and axle is made of stainless steel, reducing the weight of the rear car and using it By using a high-strength member at the portion to which the intermediate stress is applied, it becomes possible to obtain a panel-assembled rear car that is lightweight and durable.
