Summary of the invention
The utility model purpose provides a kind of locate mode hinge means, its position structure is a recessive type position structure of being located at hinge means inside, can avoid the in use ubiquitous lubricated phenomenon that has some setbacks that causes because of dust engaging friction face of exposed structure, and then improve working life; The utility model compact structure is easy to assembly simultaneously, can reduce production, assembly cost.
The technical solution of the utility model is: a kind of locate mode hinge means, comprise rotating shaft, described rotating shaft one end is fixed with support, the other end of described rotating shaft is provided with fixed block, also be provided with the bolster that can rotate with respect to rotating shaft in the described rotating shaft, take turns with fixing recessed of bolster and with the fixing cam of rotating shaft, also be provided with in the described rotating shaft and the fixing locating piece of bolster, be provided with radially outstanding locator protrusions with the locating piece position corresponding part in the described rotating shaft, described locating piece is provided with the positioning runner that cooperates slip with locator protrusions.
The further technological scheme of the utility model is: a kind of locate mode hinge means, comprise rotating shaft, described rotating shaft one end is fixed with support, the other end of described rotating shaft is provided with fixed block, also be provided with the bolster that can rotate with respect to rotating shaft in the described rotating shaft, take turns with fixing recessed of bolster and with the fixing cam of rotating shaft, also be provided with in the described rotating shaft and the fixing locating piece of bolster, be provided with radially outstanding locator protrusions with the locating piece position corresponding part in the described rotating shaft, described locating piece is provided with the positioning runner that cooperates slip with locator protrusions.
Described rotating shaft is provided with mounting hole radially, is mounted with locating stud in the described mounting hole, and described locating stud radially protrudes in the outer outer end of rotating shaft and forms described locator protrusions.
Described positioning runner is the arc groove that locating piece is provided with, and described arc groove radially inner side is communicated with the rotating shaft perforation of locating piece.
The utility model advantage is:
1. position structure of the present utility model is a recessive type position structure of being located at hinge means inside, can avoid the in use ubiquitous lubricated phenomenon that has some setbacks that causes because of dust engaging friction face of exposed structure, and then improve working life.
2. the utility model compact structure is easy to assembly, can reduce production, assembly cost.
3. the utility model can reduce concavo-convex friction stroke of taking turns, thereby has effectively reduced the concavo-convex degree of wear of taking turns, and prolongs its working life.
