Abstract

The invention relates to the technical field of automobile parts, in particular to a urea cover device which comprises a lock body, a lock cylinder is arranged in the lock body, a rotating disc is arranged on the lower end face of the lock body, a clamping base is arranged on the rotating disc, and a spring bolt is arranged between the lock body and the clamping base. The lock cylinder is driven to rotate, linkage between the lock body and the clamping base can be achieved, a tooth opening check ring is arranged on the lock cylinder through a clamping ring, and the tooth opening check ring isin clearance fit with the lock cylinder. The urea cover device is simple in structure, can seal a filling opening of a urea tank, and can also play an anti-theft role at the same time.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a urea cover device. Background technique [0002] With the upgrading of automobile emission regulations, many vehicles adopt the intelligent control of selective catalytic reduction system to treat nitrogen oxides in vehicle exhaust and convert them into harmless nitrogen and water. This technology generally uses urea solution as a reducing agent , so the vehicle needs to be equipped with a urea tank. When the urea solution in the urea tank, in order to prevent the urea solution from leaking out, a urea cover with good sealing performance is required to seal the urea tank. [0003] In the prior art, when assembling the urea cover, the tooth gap retaining ring and the lock cylinder are in an interference fit, which is difficult to assemble. When the urea cover is pressed together, several scratches will be left on the contact surface of the tooth gap retaining ring and ...
