Riveting type active engine hood hinge capable of preventing function failure of locking elastic pin

Abstract

The invention belongs to the technical field of hinge application, and discloses a riveting type active engine hood hinge capable of preventing function failure of a locking elastic pin, which comprises a limiting pin, a gasket is riveted at the tail end of the limiting pin, an external thread sleeve is arranged on the outer side of the limiting pin, and the middle of the inner side of the external thread sleeve is in sliding connection with the limiting pin. The tail end of the limiting pin and the gasket are arranged on the outer side of the external thread sleeve, external threads are arranged on the outer side of the external thread sleeve, the middle of the external thread sleeve protrudes to be hexagonal, and a telescopic spring is arranged on the outer side of the limiting pin and located on the inner side of the external thread sleeve. An integrated limiting pin structure is adopted, the outer diameter of the limiting pin coated with paint on the surface is completely sunk into an inner diameter hole of the external thread sleeve, the situation that the inner wall of the external thread sleeve is provided with a coating and has no coating resistance is avoided, the limiting pin can be freely popped out with the locking function, the front cover is limited to fall back, and the position of pedestrians is safely protected.

Description

technical field [0001] The invention belongs to the technical field of hinge application, and in particular relates to a riveted active hood hinge for preventing the failure of the locking spring pin function. Background technique [0002] The flattened nut of the existing active hood hinge is easy to accumulate paint coating, which increases the resistance of the flattened nut to pop out, the flattened nut cannot be ejected, and the function of the locking mechanism fails, resulting in unprotected pedestrians; the flattened nut and the internal screw thread Connection, the precision and size are poor, and the manufacturing and mold costs are high; the parts are small and inconvenient to clamp, the tightening torque needs to be set, and the installation cycle is long; the structure is complex and the process is unstable. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a riveted active hood h...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a riveted active hair cover hinge that prevents the function of the locking spring pin from failing, which solves the problem of easy accumulation of paint coating on the flattened nut of the active hair cover hinge in the prior art, which increases the The resistance of the flattened nut to eject, the pinned flat nut cannot be ejected, and the function of the locking mechanism fails, resulting in unprotected pedestrians; the threaded connection between the flattened nut and the internal screw has poor precision and size, and the manufacturing and mold costs are high; the parts are small, Inconvenient clamping, tightening torque needs to be set, and the installation cycle is longer; the structure is complex and the process is unstable
