The utility model mainly comprises two metal plates which adopt flexible connection, a shaft which is used to connect with the two metal plates, and a spring which is sheathed on the shaft. The utility model is characterized in that the shaft which is used to connect with the two metal plates is added with the spring at the middle, one end of the spring and the metal plates are fixed with each other and are fixed on the same shaft, and the other end of the spring and the metal plates can be fixed with each other and can release the fixation. When the room door is needed to be in a normally closed state, by using the utility model, a special man or a passing man does not need to close the door even if the man passes through, and the self-closing function of the room door can be realized; when the room door is in a normally open state, the requirement can be satisfied by releasing the spring action; thereby, the beautiful appearance is realized, the convenient use is realized, and the requirement of the people daily living and work can be satisfied.
Description
The utility model relates to a kind of door hinge, particularly about a kind of door hinge that has spring.
Existing door hinge is to adopt two metal sheets mostly, connects with a metal shaft.When closing, must if personnel come in and go out,, conveniently door not closed, cause interior temperature reduction or sound transmission, must door be shut the special messenger with manually door being closed especially at office or dwelling house, very inconvenient.The door of many dwelling houses or office has to be nailed on extension spring or leather strap is closed door automatically, but seems that like this room utmost point is not attractive in appearance.Though existing free swinging door hinge can be closed door automatically, this hinge can only use in the gate of office building etc., and is very inconvenient.
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of common door hinge that has spring to be provided.
Technical solution of the present utility model is: a kind of swinging door hinge is two metal sheets that flexibly connect by adopting substantially, the axle and the spring in the middle of axle that connect two metal sheets constitute, and it is characterized in that: the centre at the axle that connects two metal sheets is added with spring.
Above-described centre at the axle that connects two metal sheets be added with spring be with spring housing on axle.
Described spring one end is fixing with the axle bottom, and the other end and a sheet metal join, and can insert on the metal sheet of being with the pin sheet it is fixed.
The utility model is compared with existing door hinge, when the room need be in normally off, even there is flow of personnel also must the special messenger not close the door or the mobile personnel shuts the door after you; When door need often be opened, can remove fixing at pin sheet upper spring one end, make the utility model just the same with existing door hinge function, be easy to use, attractive in appearance.
Accompanying drawing 1 is an assembling schematic diagram of the present utility model.
Accompanying drawing 2 is the utility model spring and jackshaft connection diagram.
Embodiment:
Hinge plate 1 adopts iron plate processing respectively with hinge plate 2, hinge plate 1 Lower Half left side turnup is made hollow cylinder 3, iron central axis 4 is fixed in the hollow cylinder, at central axis 4 outer rim shock mounts 5, the lower end of spring 5 is fixed in the slit 6 of the hollow cylinder that rolls 3 and central axis 4, the fixedly connected sheet metal 7 in the upper end of spring 5, make hollow cylinder 8 at hinge plate 2 first half right side turnups, its top half is clipped, sheet metal 7 is passed, be fixed in the pin sheet 9 that the upper left corner of hinge plate 2 suppresses, be shaped on screw hole 10 on the hinge plate 1 and 2 and hinge plate 1 and 2 can be respectively fixed on door and the doorframe.When the needs door is closed automatically, sheet metal 7 is fixed in the pin sheet 9, because the effect of spring lumps together hinge plate 1 and 2, reach the effect of closing door.When not needing to close, sheet metal 7 is separated with pin sheet 9, make spring not the effect of producing get final product.
