AI Technical Summary
Technical Problem
The existing fuel tank clamp forgings have weak metal-to-metal friction, which makes them prone to loosening when the fuel tank vibrates, thus reducing safety.
Method used
An arc-shaped groove is made on the inner wall of the fuel tank band and rubber and nylon strips are bonded together to enhance friction. The elastic locking structure protects the connection ends of the fastening bolts and nuts, improving the fastening and shock absorption effect.
Benefits of technology
It increases the friction between the fuel tank clamp and the fuel tank, reduces loosening caused by vibration, enhances safety and stability, and has a buffering and shock absorption function, extending service life.

Abstract
The utility model belongs to the technical field of fuel tank strap forgings, and particularly relates to a high-tightness fuel tank strap forgings, which comprise a first fuel tank strap and a second fuel tank strap, the first fuel tank strap and the second fuel tank strap are symmetrically distributed, and fastening bolts penetrate through the ends of the first fuel tank strap and the second fuel tank strap. The penetrating end of the fastening bolt is in threaded connection with a fastening nut. The two first arc-shaped grooves and the second arc-shaped groove are formed in the inner wall of the first oil tank strap body and the inner wall of the second oil tank strap body respectively, then the rubber strips are bonded in the first arc-shaped grooves, the nylon strips are bonded in the second arc-shaped grooves, and when the first oil tank strap body and the second oil tank strap body are arranged on the outer wall of an oil tank in a sleeving mode and bolts are tightened, the rubber strips can be tightened. The first oil tank strap and the second oil tank strap extrude the rubber strip and the nylon strip, so that the friction force and the fastening performance between the strap forge piece and the oil tank are improved, the buffering and damping effects can be achieved, and the situation that the strap forge piece is loosened due to vibration is reduced.
