Compared with prior art, shop front hinge in the technical solution of the utility model and doorframe hinge are step-like, like this, when the people attempts hinge pried open, step has served as the defence line one, and the burglar also must pry open the part of crossing step on the hinge except the planar section of hinge being pried open, this has just increased the difficulty of prying open greatly, has strengthened the function of pick-proof.

Step on shop front hinge and the doorframe hinge all has only one, a step also can play the effect of anti-sledge, and as long as described moved end face and residing of quiet end face leave the gap between the end face away from bearing pin when shutting state when being in, just can eliminate extruding elasticity, simple in structure.

On the hinge after the improvement, shoulder height on shoulder height on the shop front hinge cross section and the doorframe hinge cross section is inequality, this makes when the shop front is in closed condition, the latter half of shop front hinge and doorframe hinge, just away between the shop front hinge of bearing pin and the doorframe hinge certain clearance being arranged, like this, even the angle between the side door face and the preceding shop front can not produce the problem that extruding takes place between the doorframe and the shop front when closing the door greater than 90 degree yet, therefore make the processing of door more convenient.

Described shop front hinge and doorframe hinge on bearing pin for arranging up and down, its with the pin joint of bearing pin also for arranging that up and down such structure is comparatively simple, easy processing.

In addition, between the pin joint of described shop front hinge and bearing pin and the pin joint of doorframe hinge and bearing pin pad is installed, can makes rotation more flexible like this.

The beneficial effects of the utility model are: the shop front hinge after 1, improving becomes step with the doorframe hinge design, has strengthened the function of pick-proof; Even the angle between the 2 side door faces and the preceding shop front is greater than 90 ° of problems that also can not produce extruding, therefore the processing of door is convenient; 3, simple in structure, performance attractive in appearance is good.
