Abstract
Description
Technical Field
[0001] The utility model relates to the field of door hinge structures, and more particularly to a push-pull hinge for internal installation. Background Art
[0002] Hinge is a linking device widely used in daily life and industrial production. It is mainly used to connect objects such as doors and windows to enable them to rotate freely. The opening and closing size of the hinge, also known as the rotation angle of the hinge, refers to the maximum angle that the door or lid can rotate when opening or closing. The existing internally installed hinges can only open the door or lid to a certain angle due to the limitation of the installation position. The maximum opening and closing of ordinary internal hinges is generally 90°, which has certain limitations. If the door or lid is too thick or has protrusions, it will also affect the passability. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a push-pull hinge for internal installation, which can reduce the restrictions on the installation position, increase the opening and closing angle of the hinge, and effectively prevent the door or cover from being too thick to affect the passability.
[0004] The purpose of the utility model is achieved through the following technical solutions.
[0005] The utility model is a push-pull hinge for internal installation, comprising a slide rail with a through slot, a guide block sliding along the through slot is arranged on the slide rail, and one end of the slide rail is connected with a mounting angle through a rotating shaft.
[0006] Furthermore, a screw mounting hole is provided at the bottom of the guide block, the lower part of the guide block is located in the through slot of the slide rail, and is fixed to the inner side of the box or door frame by a No. 1 screw, and the relative sliding of the guide block and the slide rail is achieved by pulling the slide rail.
[0007] Furthermore, the installation angle is provided with a screw installation hole, which is fixed to the inner side of the door or cover by a No. 2 screw, and the door or cover can be rotated outward to open at an angle greater than 90 degrees through the rotating shaft.
[0008] Compared with the prior art, the beneficial effects brought about by the technical solution of the utility model are:
[0009] In the utility model, the slide rail and the guide block are fixed on the inner side of the box or door frame, the installation angle is fixed on the inner side of the door or cover, the guide rail and the installation angle are rotatably connected, the door or cover can be pulled out horizontally under the action of the slide rail and the guide block, and when pulled to the limit position, the door or cover can be flipped outwards under the action of the rotating shaft to open at an angle greater than 90 degrees, so that the protrusion on the door or cover is completely outside the box or door frame outlet, and will not affect the entrance passability. The utility model can reduce the restrictions on the installation position, increase the opening and closing angle of the hinge, and effectively prevent the door or cover from being too thick to affect the passability.
[0010] The utility model has the characteristics of simple structure, convenient assembly, safety and reliability, low production cost, internal installation, concealed and beautiful appearance, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] like Figure 1 and Figure 2 As shown, the utility model proposes a push-pull hinge for internal installation, which is mainly composed of a slide rail 1, a guide block 2, a rotating shaft 3, and an installation angle 4. The slide rail 1 is provided with a through groove along the length direction, and the slide rail 1 is provided with a guide block 2 that can slide along the through groove. One end of the slide rail 1 is connected to the installation angle 4 through the rotating shaft 3.
[0021] In the above hinge, a screw mounting hole is provided at the bottom of the guide block 2, the lower part of the guide block 2 is located in the through slot of the slide rail 1, and is fixed to the inner side of the box or door frame 9 by a No. 1 screw 5. By pulling the slide rail 1, the guide block 2 and the slide rail 1 can slide relative to each other. Figure 3 shown.
[0022] In the above hinge, the installation angle 4 is similarly arranged in an L shape, and is provided with a screw installation hole, and is fixed to the inner side of the door or cover 7 by a No. 2 screw 6, and the door or cover 7 is rotated outward by the rotating shaft 3 to open at an angle greater than 90 degrees. Figure 4 shown.
[0023] When using, the user first uses the No. 1 screw 5 to fix the slide rail 1 and the guide block 2 to the inner side of the box or door frame 9, and then fixes the door or cover 7 to the end of the installation angle 4 with the No. 2 screw 6. When opening the door or cover 7, first pull the door or cover 7 out horizontally, such as Figure 5 As shown, when pulled to the limit position, the door or cover 7 is flipped outward to open, as shown in FIG. Figure 6 As shown, at this time, the protrusion 8 on the door or cover 7 is completely outside the outlet of the box body or door frame 9 and will not affect the accessibility of the entrance.
[0024] Although the functions and working processes of the utility model are described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific functions and working processes, and the above-mentioned specific implementation methods are merely illustrative rather than restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the utility model and the claims, which are all within the protection of the utility model.
