Description
Technical field
The utility model relates to a kind of door hinge.
Background technology
Existing door hinge comprises first rotating shaft of first hinge seat, second hinge seat, first hinge seat; And second rotating shaft of second hinge seat; What first rotating shaft was rotated is enclosed within second rotating shaft.During installation, this door hinge has directionality, and second hinge seat can only be installed on the doorframe, and first hinge seat can only be installed on the door, installs, uses inconvenience, can not automatically reset after opening the door.
The utility model content
Of the present utility model is to overcome the deficiencies in the prior art and provide that a kind of first hinge seat or second hinge seat can be random be installed on the doorframe or on the door, do not have directionality, install, easy to use, and can automatically reset a kind of door hinge after opening the door.
In order to achieve the above object, the utility model is achieved in that it is a kind of door hinge, comprises first rotating shaft of first hinge seat, second hinge seat, first hinge seat and second rotating shaft of second hinge seat; It is characterized in that: also comprise back-moving spring and pivot pin; The interlude of first rotating shaft is provided with an opening, thereby first rotating shaft is divided into upper and lower diaxon, is provided with axis hole on last axle, and lower shaft is a blank pipe; Second rotating shaft is inserted in the opening of first rotating shaft, in second rotating shaft, be provided with axis hole, second rotating shaft and last axle are rotationally connected by pivot pin, in second rotating shaft, be provided with a cavity that is communicated with the blank pipe of lower shaft, back-moving spring is located in the blank pipe and cavity of lower shaft, one end of back-moving spring and the base of cavity are fixed, and the blank pipe inwall of the other end and lower shaft is fixed.
Also comprise the end cap friction tight in the blank pipe that is located at lower shaft, on end cap, also be provided with the insertable groove of back-moving spring one end with it.
At the anti-skidding raised line more than two of being axially arranged with of the blank pipe inwall of described lower shaft, at the anti-skidding convex tendon more than two of being axially arranged with of end cap outer wall, thereby anti-skidding raised line and anti-skidding convex tendon are worked in coordination and are prevented that end cap from rotating.
The tail end of described pivot pin is provided with the friction tight anti-skidding raised line of axis hole that makes itself and last axle.
Be provided with a jack on the base of the cavity of described second rotating shaft, the other end of back-moving spring inserts in this hole.
The utility model advantage compared with prior art is, first hinge seat or second hinge seat can be random is installed on the doorframe or on the door, does not have directionality, installs, easy to use, and can automatically reset after opening the door, and is simple in structure, low price.
Description of drawings
Fig. 1 explosive view of the present utility model;
Fig. 2 is second hinge seat of Fig. 1 and the stereogram that pivot pin cooperates.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in the figure, it is a kind of door hinge, comprises first rotating shaft of first hinge seat 1, second hinge seat 4, first hinge seat, second rotating shaft 41, back-moving spring 2 and the pivot pin 5 of second hinge seat.The interlude of first rotating shaft is provided with an opening 14, thereby first rotating shaft is divided into upper and lower diaxon 11,13, is provided with axis hole 111 on last axle, and lower shaft is a blank pipe; Second rotating shaft is inserted in the opening of first rotating shaft, in second rotating shaft, be provided with axis hole 411, pivot pin 5 passes axis hole 111 and axis hole 411 second rotating shafts and last axle and is rotationally connected, in second rotating shaft, be provided with a cavity that is communicated with blank pipe 413, back-moving spring is located in the cavity of the blank pipe of lower shaft and second rotating shaft, one end of back-moving spring and the base of cavity are fixed, and the blank pipe inwall of the other end and lower shaft is fixed.In the present embodiment, also comprise the end cap friction tight 3 in the blank pipe that is located at lower shaft 13, on end cap, also be provided with back-moving spring one end 22 insertable grooves 31 with it; At the anti-skidding raised line 131 more than two of being axially arranged with of lower shaft blank pipe inwall, at the anti-skidding convex tendon 32 more than two of being axially arranged with of end cap outer wall, thereby anti-skidding raised line and anti-skidding convex tendon work in coordination and prevent that end cap from rotating, make an end 22 location of back-moving spring.Be provided with a jack 412 on the base of the cavity 413 of second rotating shaft, the other end 21 of back-moving spring inserts in these holes, makes the back-moving spring location, thereby produces torsion.The tail end of pivot pin 5 is provided with the axis hole 111 friction tight anti-skidding raised lines 51 that make itself and last axle, thereby prevents that pivot pin from rotating.
