[0002] All-terrain vehicles are vehicles that can travel on any terrain and can move freely on terrain that is difficult for ordinary vehicles to maneuver. They are commonly known as beach cars in China. Because their structure is very similar to that of motorcycles and many of their parts are common to motorcycles, some people also call them "four-wheeled motorcycles". This type of vehicle has multiple uses and is not restricted by road conditions. It is widely used in North America and Western Europe, and its use is increasing year by year.

[0003] In the prior art, all-terrain vehicles often travel on bumpy roads, and the fuel tank at the bottom is prone to collide with hard objects on the ground. At the same time, the shaking during driving and the high temperature will cause the pressure in the fuel tank to continue to increase. Failure to release the pressure in time will lead to excessive air pressure, which is prone to explosion during collision. For this reason, we propose an explosion-proof fuel tank structure for all-terrain vehicles. Utility Model Content

The weight block 67 is fixedly installed at the upper end of the sealing plug 66. The number of the weight blocks 67 can be increased according to actual needs. When the air pressure in the fuel tank 1 is too high, the gas flows upward through the pressure relief channel 63 of the pressure relief pipe 61. Since the telescopic spring 64 and the weight block 67 are designed according to the limit pressure, when the pressure reaches the limit value, the telescopic spring 64 can begin to stretch, thereby causing the sealing plug 66 to slide upward along the pressure relief channel 63, and the gas is released along the pressure relief channel 63. After the pressure returns to normal, the telescopic spring 64 shrinks and recovers, and the seal is restored through the sealing sleeve 68, which can relieve the pressure in time to avoid the explosion of the fuel tank 1 due to excessive pressure, thereby improving the safety of the fuel tank 1 of the all-terrain vehicle.
