Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hinges, and more specifically, to a hinge that can be positioned. Background Art
[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. Hinge joints are mainly installed on doors and windows, while hinges are more installed on cabinets. Classified by material, they are mainly divided into stainless steel hinges and iron hinges.
[0003] Currently, a hinge usually consists of a movable hinge and a stationary hinge. The stationary hinge is fixed on the frame, and the movable hinge is fixed on the door panel to achieve the function of opening and closing the door. When the hinge is applied to the door panel, it is necessary to distinguish the directions of the stationary hinge and the movable hinge during the assembly process to assemble. However, most of the existing stationary hinges and movable hinges are not easy to distinguish the directions during assembly, are prone to being installed incorrectly during assembly, and the assembly production efficiency is low. Moreover, during the use of the hinge, under the slight action of external force, the door panel will move, and it cannot be positioned according to actual needs. Summary of the Utility Model

[0006] 2. Technical Solutions
[0007] To solve the above problems, the utility model adopts the following technical solutions:
[0008] A hinge that can be positioned includes a stationary hinge and a movable hinge. The movable hinge is movably hinged inside the stationary hinge. A hinge shaft is detachably connected to the stationary hinge, and the movable hinge is rotatably connected to the circumferential surface of the hinge shaft. A screw hole is formed in the movable hinge. A stop shaft is slidably connected in the screw hole, and one end of the stop shaft penetrates to the outside of the movable hinge and corresponds to the stationary hinge. A spring is arranged in the screw hole. A machine screw is threadedly connected in the screw hole, and the spring is located between the stop shaft and the machine screw. A set of positioning holes are formed in both symmetric side walls of the stationary hinge, and both sets of positioning holes match the stop shaft.
[0009] As a preferred embodiment of the present utility model, the hinge shaft includes a threaded shaft and two nuts. The threaded shaft is movably inserted into the static hinge, and the two nuts are respectively threadedly connected to the two ends of the threaded shaft corresponding to the static hinge.
[0010] As a preferred embodiment of the present utility model, a limiting protrusion is fixedly connected inside the static hinge, and the limiting protrusion corresponds to the moving hinge.
[0011] As a preferred embodiment of the present utility model, a set of mounting holes are provided on both the static hinge and the moving hinge, and each set of mounting holes is set to four.
[0012] 3. Beneficial effects
[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] (1) In this solution, the static hinge and the moving hinge are hinged through a hinge shaft. The assembly between the moving hinge and the static hinge does not need to be in a specific direction, so it will not be misassembled during assembly, and the assembly production efficiency is high. After the static hinge and the moving hinge are assembled, the stop shaft corresponds to any set of positioning holes, and the machine screw restricts the stop shaft and the spring in the screw hole. The elastic force of the spring acts on the stop shaft. When the static hinge and the moving hinge rotate, they are clamped by the stop shaft and a set of positioning holes, which can be positioned to keep the door panel stable and prevent the door panel from being accidentally closed under slight external force.

A screw hole 4 is formed in the moving hinge 2. A stop shaft 5 is slidably connected in the screw hole 4, and one end of the stop shaft 5 penetrates to the outside of the moving hinge 2 and corresponds to the static hinge 1. A spring 6 is arranged in the screw hole 4. A machine screw 7 is threadedly connected in the screw hole 4, and the spring 6 is located between the stop shaft 5 and the machine screw 7. A set of positioning holes 8 are formed in both symmetric side walls of the static hinge 1, and both sets of positioning holes 8 match the stop shaft 5.
[0025] In this embodiment, the stop shaft 5, the spring 6 and the machine screw 7 are sequentially placed in the screw hole 4. The machine screw 7 is threadedly connected in the screw hole 4 to limit the stop shaft 5 and the spring 6 in the screw hole 4, so that the elastic force of the spring 6 acts on the stop shaft 5. One end of the stop shaft 5 penetrates to the outside of the moving hinge 2. The static hinge 1 is installed on the frame body, and the moving hinge 2 is installed on the door panel. The moving hinge 2 is movably hinged inside the static hinge 1 through the hinge shaft 3. One end of the stop shaft 5 corresponds to a set of positioning holes 8. Under the action of the elastic force of the spring 6, when the door panel rotates, the stop shaft 5 can be clamped into a set of positioning holes 8 to limit the rotation between the static hinge 1 and the moving hinge 2, thereby positioning the door panel.
[0026] Specifically, the hinge shaft 3 includes a threaded shaft 31 and two nuts 32. The threaded shaft 31 is movably inserted into the static hinge 1, and the two nuts 32 are respectively threadedly connected to the two ends of the threaded shaft 31 corresponding to the static hinge 1.

[0028] Specifically, a limiting protrusion 9 is fixedly connected within the static hinge 1, and the limiting protrusion 9 corresponds to the moving hinge 2.
[0029] In this embodiment, the limiting protrusion 9 limits the rotation angle between the static hinge 1 and the moving hinge 2 to prevent the door panel from rotating excessively.
[0030] Specifically, a set of mounting holes 10 are formed on both the static hinge 1 and the moving hinge 2, and each set of mounting holes 10 is provided with four.
[0031] In this embodiment, the static hinge 1 and the moving hinge 2 are fixedly installed and fixed by two sets of mounting holes 10 in cooperation with bolts. Each set of mounting holes 10 is provided with four, so that the static hinge 1 and the moving hinge 2 can be evenly stressed during installation and fixing, ensuring the installation effect.
[0032] Working principle: The static hinge 1 is installed on the frame body, and the moving hinge 2 is installed on the door panel. A stop shaft 5, a spring 6 and a machine screw 7 are sequentially placed into the screw hole 4. The machine screw 7 is threadedly connected within the screw hole 4 to limit the stop shaft 5 and the spring 6 within the screw hole 4. The elastic force of the spring 6 acts on the stop shaft 5, so that one end of the stop shaft 5 penetrates to the outside of the moving hinge 2. The moving hinge 2 is placed into the static hinge 1. The threaded shaft 31 passes through the static hinge 1 and the moving hinge 2, and then is fixed by the two nuts 32, so that the moving hinge 2 is movably hinged within the static hinge 1. One end of the stop shaft 5 corresponds to a set of positioning holes 8. Under the action of the elastic force of the spring 6, when the door panel rotates, the stop shaft 5 can be clamped into the set of positioning holes 8 to limit the rotation between the static hinge 1 and the moving hinge 2, thereby positioning the door panel.
