Abstract

The utility model relates to a door hinge device, which is especially used for a hinge leaf type general hinge for cabinet doors and furniture doors. The utility model combines the advantages of a simplified hinge and a composite hinge and overcomes the defects of the simplified hinge and the composite hinge; the utility model comprises a fixed hinge seat, a movable hinge seat, a tension spring and a pin shaft. The utility model is characterized in that the tension spring is arranged at the middle end of the fixed hinge seat, so, the fixed hinge seat and the movable hinge seat are automatically returned to form the position relation of 90DEG under the function of the tension spring and the match of the pin shaft, and the upper end of the movable hinge seat is provided with a pair of corresponding locking holes. With the structure and the mutual function of the positioning, the displacement and the tension spring, a door leaf has the advantages of reasonable structure, multiple opening angles, automatic return and locking, convenient installation, etc., when the door leaf is used.

Description

The hinge type universal hinge

The utility model is the hinge that is applied to cabinet door, furniture door.

The hinge that uses has simple type and compound two big classes at present.Simple type such as traditional hinge are made up of bearing pin and two location page or leaf, and it simple in structure can not self-return, the supporting magnetic device of needs.But its advantage is arranged, and open angle is big, arbitrarily decides angle.Another kind of compound hinge then changes traditional structure, as the tobacco pipe hinge, is formed by connecting by parts such as base, adjustment seat, elasticity butt hooks.Though it has the self-return function, open angle is installed trouble less than 90 degree.

The purpose of this utility model is: collects the advantage of above-mentioned two class hinges, overcomes their shortcoming, provide a kind of rational in infrastructure, and self-return, easy for installation, the hinge type universal hinge that open angle is many.

The purpose of this utility model is achieved by the following technical solution: the hinge type universal hinge includes and decides free bearing, free bearing alive, tension spring and bearing pin composition.Live free bearing by bearing pin with decide free bearing and be connected, it is characterized in that: decide the free bearing middle-end tension spring is housed,, decide the positions that free bearing and free bearing formation 90 alive spends and concern under the effect of tension spring and under the cooperation of bearing pin.Also open a pair of respective pin hole in the free bearing upper end of living.

Fig. 9 is the schematic diagram that the utility model self-return becomes 90 degree positions.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.

Referring to accompanying drawing 1-9, present embodiment mainly is to constitute by deciding free bearing 2, free bearing 1 alive, tension spring 3 and bearing pin 4,5,6.The two ends of deciding free bearing 2 and free bearing 1 alive are formed by connecting similar traditional hinge structure by bearing pin 4,5,6.Key is to decide free bearing 2 middle-ends tension spring 3 is housed; When Men Yi was opened to certain angle, the free bearing 1 of living lost stressed outside rotation in a flash, under the effect of tension spring 3, and the free bearing 1 self-return locking of living; Open when the door wing, make tension spring 3 elongations, the free bearing 1 of living is stressed outwards to turn to and decide free bearing 2 in line the time, becomes 180 and spends; At the same time, also rotation 30 degree of free bearing 1 of living, open angle is just greater than 180 degree; When bearing pin 6 shifted out insertion pin-and-hole 7, the door wing starts made tension spring 3 elongations.The free bearing 1 of living is stressed outwards to go to decide 2 one-tenth one of free bearings parallel, will become stepped 180 and spend.

In sum, the utlity model has obvious superiority:

1. decide free bearing and live free bearing mutually under the constraint of tension spring, auto back The position locking, not arbitrarily folding.

2. arbitrarily get angle, angle flare up 180 is spent or is spent greater than 180 degree and stepped 180.More convenient during use.

3. traditional magnetic device without the mortise mouth, is saved in the installation saving working hour.

Claims

1. the hinge type universal hinge includes and decides chain seat, free bearing, tension spring and bearing pin alive, and the two ends of deciding free bearing and free bearing alive are formed by connecting by bearing pin, it is characterized in that deciding the free bearing middle-end tension spring is housed.Under the tension spring effect and under the cooperation of bearing pin, decide free bearing and form the 90 position relations of spending with the free bearing of living.Open the pin-and-hole of a pair of correspondence in the free bearing upper end of living.

2. hinge type universal hinge according to claim 1 is characterized in that deciding the free bearing middle-end tension spring is housed, and can make free bearing self-return locking alive.

3. hinge type universal hinge according to claim 1, the pin-and-hole of a correspondence is opened in the free bearing upper end that it is characterized in that living, and can allow the rotational angle of free bearing alive become stepped 180 degree.

4. hinge type universal hinge according to claim 1 is characterized in that deciding the free bearing middle-end tension spring is housed, and the free bearing of living outwards rotates into 180 degree or spends greater than 180.
