Tool box

Abstract

The invention discloses a tool box comprising an upper frame solid, a lower frame solid and a thin-wall assembly. The tool box comprises an assembly bracket, a partial circular ring solid, a big plane and a hollow cone. A first belt body, a second belt body, a third belt body, a first curved surface solid, a second curved surface solid, a third curved surface solid, a big supporting plane and a first reinforcing convex body are fixedly connected to the lower end of the conical surface of the hollow cone in an integrated mode. The lower portion of the assembly bracket is connected with the lower frame solid in a pulling mode. The upper portion of the assembly bracket is connected with the thin-wall assembly in a pulling mode. A first curved surface, a second curved surface and a third curved surface are arranged between the first belt body and the big supporting plane. The tool box is provided with a jack upper right arm lateral bearing convex body and a jack upper left arm lateral bearing convex body. A third reinforcing convex body and the thin-wall assembly are provided with tire lever flange locating holes. The tool box is further provided with semicircular holes, hoops and related lock catches as needed and also provided with a plurality of economical holes for lowering cost. The overall tool box is made of polypropylene plastic.

Description

technical field [0001] The invention relates to a tool box, in particular to a car tool box for maintaining vehicles. Background technique [0002] There are traditional car on-board tools, and their storage conditions are not particular. From the initial on-board tools for vehicle maintenance, such as jacks, tire wrenches, towing shackles, screwdrivers and other tools, are randomly put into the toolbox. The car rattled, and now the EPP foamed plastic tray is used as the tool box for storing tools. It has undergone many improvements and has made progress in the design of car accessories and tools to further meet people's needs. However, many aspects of automobile design improvement are reflected in the reduction of cost and the improvement of the cost performance of its parts. After careful market research and product analysis by professional engineers, with the help of CAD-aided design, especially the analysis and comparison of 3D model design, industry personnel It is inc...

However, many aspects of automobile design improvement are reflected in the reduction of cost and the improvement of the cost performance of its parts. After careful market research and product analysis by professional engineers, with the help of CAD-aided design, especially the analysis and comparison of 3D model design, industry personnel It is increasingly felt that the older generation of on-board tool trays are made of EPP foamed plastics, which have insufficient strength and rigidity, are fragile, heavy, and large in size, occupying more space in the limited trunk of the car, and are expensive. High cost is a big disadvantage. Moreover, the tool is placed in the EPP tray for a long time, and the paint on the metal surface is easy to bond with the plastic tray, which affects the appearance and service life of the tool.
