1st, hinge for furniture：Difference according to combination is installed is divided into direct insertion and self-tipping type and is divided into 90 according to door-plate opening angle Degree, 100 degree, 110 degree, 180 degree, 270 degree etc., according to cabinet assemble need difference be divided into entirely cover (straight panel) partly lid (small curved) and Do not cover (big curved or embedded).

2nd, bathroom cabinet hinge bathroom, cabinet on-off times are up to thousands of up to ten thousand times, door hinge has quality just to seem particularly significant. Hinge is exactly the hinge that we are commonly called as, in usually bathroom cabinet door frequently switching process, and it is exactly hinge to stand severe tests most. The hinge seen in the market is mostly dismountable, is divided into two parts of pedestal and buckle.Hinge typically has 2 screens With 3 screens, the hinge of 3 screens is certainly better.

3rd, buffering hydraulic hinge, buffering hydraulic hinge is intended to provide a kind of shock-absorbing capacity of utilization liquid, buffering effect A kind of preferable hydro-cushion hinge.

Existing hinge when mounted, is substantially after being first hinged hinge shaft sleeve and hinge axis, then again by certainly Attack that screw will be hinged axle sleeve and hinge axis is fixed, so that being hinged for door and doorframe is realized, but using compression more than existing door-plate Plate, but the self tapping number of times between tapping screw and compression plate is very limited, i.e., on same screw, the number of times of automatic screw tapping Only 3-4 times, therefore it is unfavorable for very much the replacing of door-plate.

Utility model content

The purpose of this utility model is to provide a kind of door hinge, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides following technical scheme：A kind of door hinge, including door pivot set and door Rotating shaft, the door pivot may be rotatably mounted at the door pivot and put, and the door pivot includes rotating shaft and installs housing, the rotating shaft One end of installation housing, which is offered, is set with locking lid on external screw thread, the external screw thread, the other end of housing is installed in the rotating shaft Limited step is provided with, the two ends that housing is installed in the rotating shaft are mounted on rotating shaft, spring is provided between two rotating shafts, One end that the rotating shaft is located at rotating shaft installation housing sets the restricted rotating shaft to depart from the convex of the rotating shaft installation housing Edge, the rotating shaft is installed and guide groove is further opened with housing sidewall, and the side of the guide groove is provided with for positioning described turn Pulling block is connected with the locating slot of axle, the flange, the pulling block is slidably disposed in the guide groove.

In the utility model optional embodiment, the door pivot set is fixedly connected with articulated body, the one of the articulated body End offers mounting hole through being bent to form twice on installing plate, the installing plate.

In the utility model optional embodiment, the quantity of the locating slot is two, and is respectively used to turn described in two The positioning of axle.

In the utility model optional embodiment, the inner chamber that the flange installs housing with the rotating shaft is slidably matched.

In the utility model optional embodiment, when the pulling block is located at the corresponding locating slot, the rotating shaft is complete It is located at entirely in the rotating shaft mounting shell body.
