Embodiment Construction
[0022] Examples such as Figures 1 to 11 As shown, a fuel tank cap locking structure includes a housing 2 , a bottom cover 10 matched with the housing 2 , a lock cylinder 6 arranged in the housing 2 , a lock housing 5 and a blade 4 . The housing 2 is provided with a boss at the installation place of the lock housing 5, the boss is covered with a fixed block 7, and both the boss and the fixed block 7 are provided with a positioning structure, so that the fixed block 7 cannot rotate on the boss. The fixed block 7 is covered with a relatively rotatable block 9 , and a return torsion spring 8 is arranged between the fixed block 7 and the block 9 . The outer wall of the stopper 9 is oppositely provided with two stopper bosses 91, the fixed block 7 is provided with two deformable rotating arms 71, the rotating arm 71 is connected with the fixed block 7 through one end, and the rotating arm 71 The end of the arm is provided with the arm hook 711 that cooperates with the block boss 9...

The invention discloses a fuel tank cover locking structure which comprises a shell, a bottom cover matched with the shell, a lock cylinder, a lock shell and blades. A fixed block and a check block installed on the fixed block in a sleeving mode are fixedly installed in the shell. A reset torsional spring is arranged between the fixed block and the check block. A check block boss is arranged on the outer wall of the check block. Rotary arms are arranged on the fixed block. Rotary arm clamping hooks are arranged at the ends of the rotary arms. A locking block is further arranged in the shell. A set of locking block bosses are arranged on the inner circle of the locking block. A set of locking clamping teeth are arranged at the bottom of the locking block. A set of locking clamping hooks matched with the locking clamping teeth are arranged on the end face, matched with the locking block, of the bottom cover. According to the fuel tank cover locking structure, through cooperation of the fixed block, the locking block and the check block, the functions of automatic locking, locking prompt and idle antitheft of a fuel tank lock are achieved, and the fuel tank cover locking structure has the advantages that the structure is simple, the design is ingenious, and the number of parts is small, and can be widely applied to the field of fuel tank cover locks.
Description
technical field [0001] The invention relates to the field of automobile fuel tank caps, in particular to a fuel tank cap locking structure. Background technique [0002] The fuel tank cap of a vehicle has the functions of preventing fuel leakage and ensuring the pressure balance in the fuel tank. It is frequently used, requires easy use, stable performance, and high requirements for anti-theft and sealing. The existing fuel tank structure has a simple structure, but due to the simple structure, it cannot arrange a locking anti-theft structure, so that the anti-theft performance of the fuel tank is greatly weakened. If a locking and anti-theft structure is added, the existing structure is too complicated, inconvenient to assemble and high in cost. And the increase of the anti-theft structure makes the unlocking operation complicated, which greatly reduces the operational convenience of the fuel tank cap. Contents of the invention [0003] The object of the present inventi...
