Automobile cardan joint transmission shaft packaging paper box

Abstract

The invention relates an automobile cardan joint transmission shaft packaging paper box,which mainly solves the problem of easy damage owing to the low supporting strength of the existing ball cage assembly packaging paper box. The packaging paper box is characterized in that both ends of a box body (1) with a supporting paperboard (2), the middle which is provided with a through hole (3); the supporting paperboard (2) is folded, and then forms a triangulate with the end surface (5) of the box body (1); after the supporting paperboard (2) is folded, the through hole is caused to be matched with an end socket of the ball cage assembly. The cardan joint transmission shaft changes supporting form of two end sockets in the box body, adds supporting strength of the paper box on the ball cage assembly while not adding the cost of the paper box, does not change outline size of the original box body, and is characterized by convenient assembly, simple structure, low cost and being difficult to damage.

Description

Technical field: [0001] The invention relates to an outer packaging of auto parts, in particular to a packaging carton for an automobile universal joint transmission shaft. Background technique: [0002] The car universal joint drive shaft is a common part of the car, and its assembly accuracy and processing accuracy are relatively high, so its packaging is very important during transportation. At present, the known ball cage type universal joint transmission shaft (hereinafter referred to as the ball cage assembly) assembly carton is made of a piece of cardboard punched and folded according to the traces. After folding, the closed parts are inserted into each other to form a cuboid The box body, the cardboard at both ends of the box body extends into the box body and sticks to the side walls of the box body to form auxiliary supports at both ends. The support of the ball cage assembly relies on the four walls of the carton, the auxiliary supports at both ends and the "U Th...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing packaging cartons for universal joint transmission shafts of automobiles, which have low supporting strength and are easy to be damaged, the present invention provides a packaging paper box for transmission shafts of automobile universal joints. The support form at both ends of the box body does not increase the cost of the carton, and at the same time increases the support strength of the carton to the drive shaft of the car universal joint. The characteristics of damage and low cost
