Abstract

The utility model provides an exterior gemel, consisting of a fixed hinge, a rotary hinge and a gemel shaft. Assembly screw holes and gemel holes alternately arranged in the same shaft. The rotary hinge is a pair of splints level with the gemel shaft and connected by a connector. The assembly screw holes are arranged in the interior splints and the gemel holes are arranged in the terminal part of the connector extending outward. A concave trough corresponding with the connector of the rotary hinge is arranged in the fixed hinge. The rotary hinge and the door leaf are connected by the splints and no special welded material is needed to fix the gemel, which saves much work and simplifies the door structure and manufacturing process. The fastening piece to assemble the gemel is arranged on the interior splints of the rotary hinge to avoid exposure to the exterior of the door body, which simplifies and beautifies the structure, fastens the assembly and is particularly applicable to doors of appliance boxes or cabinets. Besides, no trap occurs in the rotation of the rotary hinge and the unlocking angle reaches 180 degrees, which improves the conditions of human and mechanic operation.

Description

External hinge

Technical field

The utility model relates to a kind of hinge, the External hinge that metal cabinet doors such as particularly a kind of cabinet, rack use.

Background technology

The door body rotation folding of cabinet, rack all will be used hinge.Hinge commonly used at present has built-in and external two kinds, External hinge is installed in the outside of a body, form by Fixed hinge, rotation hinge and hinge axis, Fixed hinge, rotation hinge are fixedlyed connected with casing, a door body respectively by screw, the pan for the hinge axis insertion that has alternately mutual and coaxial setting on it is by the cooperate folding that realize body of hinge axis with pan.External hinge mostly need be on the door body relevant position perforate and hinge bodies assemble, at the assembling securing member that can see hinge in appearance mostly of door body, influence attractive in appearance like this.Also have at door body interior welds section bar, the hinge assemblies relation is embodied on the section bar,, but strengthened the workload of design, need design section bar separately though be the requirement that has reached attractive in appearance like this.And, be difficult to guarantee the quality of section bar welding and assembling for the cabinet of thinner thickness, the door body of rack, it is unreliable to cause connecting.In addition, at present common External hinge opening angle is little, generally can not surpass 140 degree, brings some inconvenience to operation.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of both artistic and practical, assembling firmly and opening angle can reach the External hinges of 180 degree.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of External hinge, its composition comprises Fixed hinge, rotates hinge and hinge axis, Fixed hinge, rotate and to have mounting screw hole and mutually alternately and the pan of coaxial setting on the hinge, it is characterized in that described rotation hinge for the pair of parallel that connects by connector in the clamping plate of hinge axis, its mounting screw hole is positioned on the inboard clamping plate, its pan is arranged in the outward extending end of connector, has on the described Fixed hinge and the corresponding groove of rotation hinge connector.

The beneficial effects of the utility model are as follows: rotate the mounting means that adopts clamping plate type between hinge and the door body, therefore not needing to weld special section bar fixes hinge, has reduced the workload of design, has simplified door body structure and processing technology; The securing member that hinge is installed is located on the inboard clamping plate that rotate hinge, avoid exposing the outside at the door body, succinctly attractive in appearance, install firm, reliable, spacing at above-below direction of hinge and Fixed hinge be can realize in the rotation process rotating, the cabinet of thinner thickness, a body of rack are particularly useful for; The unique design of rotating hinge makes it not have the dead angle in rotation process, and opening angle can reach 180 degree, and then has improved the human-machine operation environment.

Fig. 3 is the utility model External hinge closed condition structural representation.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.

As shown in Figure 1, the utility model External hinge, its composition comprises Fixed hinge 1, rotates hinge 2 and hinge axis 3, Fixed hinge 1, rotate and to have mounting

screw hole

11,21 and mutually alternately and the

pan

12,13,22 of coaxial setting on the hinge 2, wherein rotating hinge 2 is to pass through the pair of parallel of connector 23 connections in the

clamping plate

24,25 of hinge axis, its mounting screw hole 21 is positioned on the inboard clamping plate 24, its pan 22 is arranged in connector 23 outward extending ends, has on the described Fixed hinge 1 and rotation hinge 2 connectors 23 corresponding grooves 14.

During installation, earlier fixedly hinge by the inwall of screw at cabinet, secondly door leaf is placed between the

clamping plate

24,25 that rotate hinge 2, then tighten inwards from mounting screw hole 21, make door leaf be fixed on firmly between the

clamping plate

24,25, can not come off by screw, then the connector 23 that rotates hinge 2 is inserted in the groove 14 of Fixed hinge 1, and make their

pan

12,13,22 alignment, last hinge axis 3 insertion pan from top to bottom is also fixing, has promptly finished installation.Locate during for the ease of the installation door leaf, can offer screw,, improve installation accuracy so that allow the screw that passes the mounting screw hole 21 of rotating hinge 2 enter at the corresponding site of door leaf.

Fig. 2, Fig. 3 are respectively the utility model open mode and closed condition structural representation, and number in the figure is consistent with Fig. 1.

Claims

1, External hinge, its composition comprises Fixed hinge, rotates hinge and hinge axis, Fixed hinge, rotate and to have mounting screw hole and mutually alternately and the pan of coaxial setting on the hinge, it is characterized in that described rotation hinge for the pair of parallel that connects by connector in the clamping plate of hinge axis, its mounting screw hole is positioned on the inboard clamping plate, its pan is arranged in the outward extending end of connector, has on the described Fixed hinge and the corresponding groove of rotation hinge connector.
