Abstract
The utility model discloses a spring hinge, which comprises a rotating shaft and two hinge plates that are articulated with the rotating shaft. The middle part of the rotating shaft is circled with a return spring, while the terminal tip of the return spring is lapped on the two hinge plates. The utility model has a reasonable design and a simple structure, which can let the door be at a normal open state under the function of spring load.
Description
Technical field
The utility model relates to the hinge that a kind of building door uses, particularly a kind of spring hinge.
Background technology
Usually the employed hinge of building door is to be with the page or leaf sheet and the rotating shaft of screw holes to be formed by connecting by two.In some cases, when requiring door to be in the normally open position, then need to install in addition door-inhale or other fastening devicess, use this kind hinge obviously can't be competent at above-mentioned functions separately.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provide a kind of reasonable in design, simple in structure, can make door be in a kind of spring hinge of normally open position.
The technical solution of the utility model is: a kind of spring hinge, comprise the page or leaf sheet 2 that rotating shaft 1 and two and rotating shaft 1 are hinged, and it is characterized in that: the middle part that is positioned at rotating shaft 1 is wound with a spring 3, and the two ends of described spring 3 are overlapped on respectively on two page or leaf sheets 2.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, and is simple in structure, under the effect of spring force, can make door be in normally open.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises the page or leaf sheet 2 that a rotating shaft 1 and two and rotating shaft 1 are hinged, the middle part of described rotating shaft 1 is wound with the back-moving spring 3 of a helix, on the surface of two page or leaf sheets 2, be suppressed with groove 4, back-moving spring 3 two ends 5 embed and are arranged in two grooves 4 on the page or leaf sheet 2, and are connected and fixed by bonding agent 6 and groove 4.
During the utility model work,, two page or leaf sheets 2 are set to often open shape by back-moving spring 3 is set.Under interim external force effect, owing to overcome the elastic force of back-moving spring 3, two page or leaf sheets 2 can be closed and close, door is closed, in case the external force of losing, under the effect of elastic force, back-moving spring 3 forces two page or leaf sheets 2 to reopen, thereby makes door keep normally open.
Claims (3)
