AI Technical Summary

Technical Problem

Existing fuel tanks are easily stolen by thieves using rechargeable drills and metal hole openers to drill holes, especially in scenarios such as cargo vehicles and engineering vehicles.

Method used

A honeycomb metal structure is arranged at the interlayer part of the oil tank, and the structure is rigidly connected to the inner and outer box shells, and the structural height exceeds the working depth of the hole opener on the market. When the hole opener tries to break the outer box, the honeycomb structure will be pushed against the bottom surface of the hole opener, preventing further penetration, thereby preventing theft.

Benefits of technology

It effectively prevents theft and protects the safety of the inner oil tank by preventing the deep penetration of the hole opener.

Abstract

Aiming at the problem that oil is stolen when an electric tool tapper is used for punching, the vehicle oil tank capable of preventing oil theft adopts the design of an inner shell and an outer shell, and a honeycomb-shaped metal structural body (the hole diameter is about 5.5 mm) or a column / needle array is arranged in an interlayer and is rigidly connected with a tank body. When an oil stealer breaks the outer-layer box body through the tapper, the honeycomb-shaped structural body can abut against the inner bottom face of the tapper to prevent the tapper from rotating downwards, the inner-layer box body is prevented from being damaged, and theft prevention is achieved. The fuel tank structure can adapt to different vehicle types, the interlayer mainly covers the attacked faces (the upper side, the outer side, the front portion and the rear portion), and the fuel tank structure is suitable for trucks, engineering vehicles and other scenes.

Description

[0001] 1. The purpose of the double-layer fuel tank of the present invention is mainly to prevent thieves from using a rechargeable hand drill to drill holes in the fuel tank and extract the stolen oil with a metal hole opener. The main application scenarios are cargo vehicles, engineering vehicles, etc.

[0002] 2. The double-layer box body is mainly arranged on the top, outside, front and rear parts of the oil tank which are easy to punch holes.

[0003] 3. Working principle: A honeycomb metal (column or needle type) structure is set in the sandwich between the double-layer oil tanks. The structure is rigidly connected to the inner and outer tank shells (firmly connected). The structure height is 50mm (can also be adjusted in actual application). This height exceeds the working depth of the hole openers on the market. When the hole opener breaks the outer tank, the honeycomb structure will press against the bottom surface of the hole opener, preventing it from turning downward and thus unable to damage the inner tank, thus achieving the purpose of anti-theft.

[0004] 4. The inner hole diameter of the honeycomb structure is about 5.5mm (can be adjusted appropriately according to actual conditions). The honeycomb structure is just one of the structural forms, and column or needle structures can also be used.

[0005] 5. The size of the fuel tank is determined according to different models. The appearance of the fuel tank can be adjusted appropriately as needed, and the internal structure can also be adjusted along with the external shape. Description of the drawings: Figure 1 This is the plan view of the fuel tank. Figure 2 This is the elevation view of the E and F sides of the fuel tank. Figure 3 This is a cross-sectional view of the E and F sides of the fuel tank. Figure 4 The fuel tank is a C and B elevation view. Figure 5 This is the elevation view of the B and C sides of the fuel tank. Figure 6 This is the cross-sectional view of the fuel tank on the B and C sides. Figure 7 It is a cross-sectional view of the C and B sides of the fuel tank.

Claims

1. An oil tank with a drilling hole structure for preventing oil theft is provided with an inner and outer shell and a honeycomb (column, needle) type structure between the two shells.

2. The device with anti-theft function according to claim 1, characterized in that A honeycomb (column, needle) type structure between two layers of box shells.
