Abstract

The external hinge consists of a fixed hinge, a rotating hinge and a hinge shaft. The fixed hinge and the rotating hinge have mounting screw holes and hinge holes arranged alternately and coaxially. The rotating hinge is a joint connected by a connecting body. For the splint parallel to the hinge axis, the mounting screw holes are located on the inner splint, the hinge holes are located in the outwardly extending end of the connecting body, and the fixed hinge has a groove corresponding to the rotating hinge connecting body. The splint type installation method is adopted between the rotating hinge and the door body, which does not need to weld special profiles to fix the hinge, which reduces the design workload and simplifies the door body structure and processing technology; the fasteners for installing the hinge are located on the rotating hinge The inner splint avoids being exposed on the outside of the door body. It is simple and beautiful, and the installation is firm and reliable. It is especially suitable for the doors of thinner chassis and cabinets; the rotating hinge has no dead angle during its rotation, and the opening angle reaches 180 degrees. Improve the man-machine operating environment.

Description

external hinge

technical field

The utility model relates to a hinge, in particular to an external hinge used for metal cabinet doors such as cabinets and cabinets.

Background technique

The hinges are used to rotate and open the doors of the chassis and cabinets. At present, there are two types of hinges commonly used: built-in and external. The external hinge is installed on the outside of the door body and consists of a fixed hinge, a rotating hinge and a hinge shaft. The fixed hinge and the rotating hinge are respectively connected to the box body and the door through screws. The body is fixedly connected, and there are hinge holes arranged alternately and coaxially for the insertion of the hinge shafts, and the opening and closing of the door body is realized through the cooperation of the hinge shafts and the hinge holes. Most of the external hinges need to open holes at corresponding positions on the door body to assemble with the hinge body, so that the assembly fasteners of the hinge can be mostly seen on the appearance of the door body, which affects the appearance. There are also profiles welded inside the door body, and the hinge assembly relationship is reflected on the profiles. Although this meets the aesthetic requirements, it increases the workload of the design, and the profiles need to be designed separately. Moreover, for thinner chassis and cabinet doors, it is difficult to ensure the quality of profile welding and assembly, which will lead to unreliable connections. In addition, the opening angle of the external hinges that are common at present is not large, and generally cannot exceed 140 degrees, which brings some inconvenience to the operation.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide an external hinge which is beautiful and practical, which is firmly assembled and whose opening angle can reach 180 degrees.

The technical scheme adopted by the utility model to solve the technical problem is as follows: an external hinge, which consists of a fixed hinge, a rotating hinge and a hinge shaft, and the fixed hinge and the rotating hinge have mounting screw holes and alternate and The hinge hole set coaxially is characterized in that the rotating hinge is a pair of splints parallel to the hinge axis connected by the connecting body, the mounting screw holes are located on the inner splint, and the hinge holes are located on the outwardly extending splint of the connecting body. In the end part, the fixed hinge has a groove corresponding to the connecting body of the rotating hinge.

The beneficial effects of the utility model are as follows: the splint-type installation method is adopted between the rotating hinge and the door body, so there is no need to weld special profiles to fix the hinge, which reduces the design workload and simplifies the door body structure and processing technology; The fasteners for installing the hinge are set on the inner splint of the rotating hinge to avoid being exposed on the outside of the door body. It is simple and beautiful, and the installation is firm and reliable. It can realize the limit of the rotating hinge and the fixed hinge in the up and down direction during the rotating process. , especially suitable for thin chassis and cabinet doors; the unique design of the rotating hinge makes it have no dead angle during the rotation process, and the opening angle can reach 180 degrees, thereby improving the man-machine operating environment.

Detailed ways

The utility model will be described in further detail below with reference to the accompanying drawings and in conjunction with the embodiments. However, the invention is not limited to the examples given.

As shown in Figure 1, the external hinge of the utility model is composed of a fixed hinge 1, a rotating hinge 2 and a hinge shaft 3. The fixed hinge 1 and the rotating hinge 2 have mounting screw holes 11, 21 and alternately And coaxial hinge holes 12, 13, 22, wherein the rotating hinge 2 is a pair of splints 24, 25 parallel to the hinge axis connected by a connecting body 23, and its mounting screw hole 21 is located on the inner splint 24, and its hinge The hole 22 is located in the outwardly extending end of the connecting body 23 , and the fixed hinge 1 has a groove 14 corresponding to the connecting body 23 of the rotating hinge 2 .

During installation, the fixed hinge is first fixed on the inner wall of the cabinet by screws, and then the door leaf is placed between the splints 24 and 25 of the rotating hinge 2, and then screwed in from the mounting screw hole 21 to make the door leaf firmly Fixed between the splints 24, 25, will not fall off, then insert the connecting body 23 of the rotating hinge 2 into the groove 14 of the fixed hinge 1, and make their hinge holes 12, 13, 22 align, and finally the hinge shaft 3 Insert the hinge hole from top to bottom and fix it, and the installation is completed. For the convenience of positioning when the door leaf is installed, screw holes can be provided at the corresponding position of the door leaf, so that the screws passing through the installation screw hole 21 of the rotating hinge 2 can enter to improve the installation accuracy.

Fig. 2 and Fig. 3 are structural schematic diagrams of the utility model in the open state and closed state respectively, and the symbols in the figures are consistent with those in Fig. 1 .
