Description

A kind of hinge

Technical field

The utility model relates to a kind of hinge joining means, especially relates to a kind of hinge.

Background technology

The hinge that uses is generally formed by hinge axis with around two hing straps of hinge axis at present.But existing this hinge has following defective: 1) hinge axis is loosening easily, and hing straps come off easily; 2) friction between the hing straps is serious, influences the life-span; 3) prize easily with common screwdriver, dangerous.

The utility model content

The technical problems to be solved in the utility model provide a kind of be difficult for loosening, friction is little, the life-span long and hinge safe in utilization.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: it comprises hinge axis and around left and right two hinges of hinge axis; It also comprise with hinge axis up and down two ends by the fixing nut of screw thread; Described left and right hinge is provided with pad between each contact end face of hinge axis.

For better reducing the friction between the hinge, between the contact end face of hinge axis, have at least a contact surface also to be provided with plain besring at left and right hinge.

For preventing to strengthen safety, establishing " it " font ladder on a slice hinge at least with the prizing of screwdriver.

The utility model is provided with hinge axis and makes it be difficult for becoming flexible by the fixing nut of screw thread in two ends up and down; Be provided with plain besring and pad between the hinge contact surface, can reduce friction, increase the life-span; Establish " it " font ladder on a slice hinge and can increase safety.
