Abstract

The utility model relates to an external hinge, including a hinge base and a hinge body, one side of the hinge base is provided with a cylindrical cavity, the lower end of the hinge body is provided with a cylindrical hinge axis, the hinge axis can be inserted into the cylindrical cavity of the hinge base and can be rotated in the cylindrical cavity. The utility model does not need a door body to make a special shape to place the hinge body, so the utility model can simplify the structure of the door body and the processing techniques; furthermore, the utility model can avoid the appearance defect of exposing a fastener by the front surface installation, the utility model has no dead angle during the rotation process, the open angle can achieve 180 degrees, the rapid installation of the door body can be achieved, compared with the current external hinges, the utility model can save about 30 percent of the installation time.

Description

A kind of External hinge

Technical field

The utility model relates to a kind of hinge, particularly a kind of External hinge that can be used for cabinet, rack.

Background technology

All to use hinge in the door body rotation folding of cabinet, rack.Hinge commonly used at present has built-in and external two kinds.External hinge is meant on the door body visible, mainly is installed in the outside of a body; Corresponding is built-in hinge with it, claims blind hinge again.The External hinge design is comparatively flexible, and outward appearance is had higher requirements.It generally is made up of two parts, and a part is installed on the cabinet framework, and another part and cabinet door body link, and by cooperating of hinge axis and pan, realizes the function of door body folding.External hinge need be made the relevant position of door body special shape mostly to place hinge bodies, and the processing of door body is just very complicated like this.And, on the door body External hinge is installed after, the Qianmen is dismounting difficulty relatively when engineering and debugging need, and can not assemble fast.In addition, at present common External hinge opening angle is little, generally can not be above 140 °.

Summary of the invention

The technical problems to be solved in the utility model be exactly existing External hinge when installing the opposite house shape specific shape need is arranged and install, dismounting inconvenience and the little problem of folding angle.

The utility model comprises hinge seat and hinge bodies.One side of hinge seat is provided with a cylindrical cavity, and there is a columniform hinge axis lower end of hinge bodies, and this hinge axis can insert in the cylindrical cavity of hinge seat and rotate in this cylindrical cavity.

The utility model advantage specific as follows:

1, do not need a body to make special shape and place hinge bodies, thereby can simplify the structure and the processing technology of a body;

2, the utility model connects with door sports association by the side, has avoided positive installation to expose the open defect of securing member;

3, do not have the dead angle in the rotation process, opening angle can reach 180 °;

4, can realize the Fast Installation of existing door body, compare, can save the set-up time about 30% with adopting existing External hinge.

The specific embodiment

As shown in Figure 1, the utility model comprises hinge seat (1) and hinge bodies (2).Hinge seat (1) comprises orthogonal cabinet installing plate (3) and hinge fixed page (4), has installing hole (5) on the cabinet installing plate (3), and hinge fixed page (4) is provided with a cylindrical cavity (6) away from an end end of cabinet installing plate (3).One side of hinge bodies (2) is provided with installing hole (7), and the thickness of opposite side is thick than the thickness of hinge bodies body, makes the upper end section of hinge bodies (2) be " b " font.Lower end in the thicker side of hinge bodies (2) thickness is provided with a columniform hinge axis (8), and this hinge axis (8) can insert the interior and rotation in this cylindrical cavity (6) of cylindrical cavity (6) of hinge seat fixed hinge page or leaf (4).

In order to limit vertically moving of hinge bodies (2), the installing plate (3) of hinge seat (1) is provided with a limited block (9) parallel with fixed hinge page or leaf (4), corresponding with it, hinge bodies (2) is located at the lower end of installing hole (7) one sides and stretches out a hinge bodies body part, form a projection (10), when hinge seat (1) and hinge bodies (2) when being in the close position (as shown in Figure 2), this projection (10) just in time can stretch into hinge bodies (2) limited block (9) and fixed hinge page or leaf (4) between.

To shown in Figure 6, hinge seat of the present utility model (1) and hinge bodies (2) are installed in the side of cabinet and door body respectively by securing member as Fig. 3.When the door body is installed, only need the hinge axis (8) of hinge bodies (1) is inserted in the cylindrical cavity of hinge seat (2), can rely on the gravity of a body self to finish installation, also only need during dismounting Men Tizhuan angle can be separated the Men Tiyu cabinet.When the door body is in closed condition, because the existence of limited block (9) has promptly limited the degree of freedom that the door body moves up and down, even flat time transportation of rack can not make a body deviate from yet like this.And, because a side of hinge seat (1) and hinge bodies (2) all adopts columned moulding, the opening angle of the door body that so just increases.Do not have the dead angle of rotation in door body rotation process between hinge seat and the hinge bodies, rotational angle can reach 180 °, and then has improved the human-machine operation environment.

Claims

1, a kind of External hinge comprises hinge seat and hinge bodies, it is characterized in that a side of hinge seat is provided with a cylindrical cavity, and there is a columniform hinge axis lower end of hinge bodies, and this hinge axis can insert in the cylindrical cavity of hinge seat and rotate in this cylindrical cavity.

2, External hinge as claimed in claim 1 is characterized in that hinge seat comprises orthogonal cabinet installing plate and hinge fixed page, has installing hole on the cabinet installing plate, and cylindrical cavity promptly is located at the side of hinge fixed page away from the cabinet installing plate.

3, External hinge as claimed in claim 1 is characterized in that a side of hinge bodies is provided with installing hole, and the thickness of opposite side is thick than the thickness of hinge bodies body, and hinge axis promptly is positioned at the lower end of this side.
