cam operated hinge assembly having improved assembling efficiency

摘要

The present invention is provided with a housing for improving the straightness of the sliding cam, and relates to a cam-operated hinge assembly configured to facilitate assembly of the rotating cam, the sliding cam and the spring for the housing, the fixing piece fixed to the cover (12) A rotary cam 10 having a guide rod 16 extending axially from its camp profile 14; The rotary cam 10 is engaged with the hill and the valley to linearly slide by interaction with the rotary cam 10, and has a through hole 26 for allowing the guide rod 16 to penetrate in the axial direction. A sliding cam 20; A housing 30 having a through structure allowing the exposure of the fixing piece 12 at one end and slidably accommodating the sliding cam 20, and having a spring supporting jaw 39 integrally formed at the other end thereof; It is interposed between the sliding cam 20 and the spring support jaw 39 while being inserted around the guide rod 16 and includes a spring for biasing the sliding cam 20 toward the rotary cam 10. The guide rod 16 is integrally provided with a radially extended coupling bundle 18 at its tip, and the housing 30 is elastically expanded by the coupling bundle 18 and then retracted to engage the coupling bundle. It is characterized in that the injection molded body provided integrally with the fracture-coupled coupling piece 34 coupled to (18).
