Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and in particular relates to a hinge with a locking mechanism. Background Art

[0002] A hinge is a common component used to connect two objects so that they can rotate relative to each other. Generally speaking, this type of hinge consists of a cup-shaped component (hinge cup) mounted on the door and a hinge body mounted on the cup-shaped component via a folded connecting rod component (or arm component). The hinge body is mounted on the inner wall surface of a frame for storing objects such as furniture, and the connecting rod component is embedded in the cup-shaped component when the door is closed.

[0003] In the prior art, during the use of hinges, the hinges are fixed to the inside of a door or door frame by bolts, so that the door or door frame can be fixed; however, when the door or window is opened, the hinge is in an open state, and when the door or window is accidentally hit, the hinge will drive the door or window to close or move. If the door or window automatically closes or moves when accidentally hit, fingers or other body parts may be pinched, which may cause accidental injuries to people or damage to items, resulting in inconvenience during use. Utility Model Content

[0004] The purpose of the utility model is to provide a hinge with a locking mechanism to solve the problems raised in the above background technology.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3 A hinge with a locking mechanism is shown, comprising:

[0020] A front cover 1, a rear cover 2 being screwed to the surface of the front cover 1 by screws;

[0021] A frame 3, wherein the frame 3 is integrally formed and disposed between the front cover 1 and the rear cover 2, wherein a lever sheet 4 is rotatably connected inside the frame 3, wherein a main rotating arm 15 is fixedly connected to a surface of the lever sheet 4, and the main rotating arm 15 is rotatably connected to the frame 3;

[0022] The locking assembly is arranged in the frame 3 and is used to limit the rotation of the lever piece 4. The slider 5 of the locking assembly limits the rotation of the lever piece 4 so that the slider 5 limits the main rotating arm 15 fixed on the surface of the lever piece 4.

[0023] The locking assembly includes an adjusting bolt 6, the slider 5 is slidably connected in the frame 3, the adjusting bolt 6 is rotatably connected to the top of the slider 5, a slot 7 is provided on one side of the slider 5, the slot 7 is matched and engaged with one end of the lever piece 4 to limit the lever piece 4 so that the lever piece 4 cannot rotate.

[0024] The surface of the slider 5 is rotatably connected to an eccentric nail 8, and a pressure cover 9 is provided on the surface of the slider 5 and on the top of the eccentric nail 8. The surface of the lever piece 4 is fixedly connected to two groups of springs 10, and the other end of the spring 10 is fixedly connected to the skeleton 3. The spring 10 can enable the main rotating arm 15 to generate an elastic reaction to the lever piece 4 when force is applied, thereby providing stability during the rotation of the lever piece 4.

[0025] A secondary rotating arm 11 is rotatably connected inside the skeleton 3, and the other ends of the secondary rotating arm 11 and the main rotating arm 15 are rotatably connected to the adjusting piece 12. An adjusting screw 13 is provided in the middle of the adjusting piece 12, and a pressing block 16 is provided at the other end of the adjusting screw 13. The pressing block 16 is screwed into the upper cover 14 by screws, and the main rotating arm 15 and the secondary rotating arm 11 can drive the adjusting piece 12 to follow the movement when rotating, and the pressing block 16 is screwed to the adjusting piece 12 by the adjusting screw 13, so that when the main rotating arm 15 and the secondary rotating arm 11 drive the adjusting piece 12 to follow the movement, the upper cover 14 can be driven to move by the pressing block 16, thereby driving the doors and windows to move through the upper cover 14, thereby realizing the opening and closing of the doors and windows.

[0026] The hinge with a locking mechanism is fixed to the door and window through the upper cover 14, and the rear cover 2 is fixed to the door and window frame. When the door and window are closed, the door and window drive the upper cover 14 to move, and the upper cover 14 drives the main rotating arm 15 and the auxiliary rotating arm 11 to rotate on the surface of the frame 3 toward the end close to the rear cover 2, and the main rotating arm 15 can drive the lever piece 4 to rotate in the frame 3 while rotating, so that the door and window can be closed. When the door and window are opened, the door and window drive the upper cover 14, and the upper cover 14 drives the main rotating arm 15 and the auxiliary rotating arm 11 to rotate on the surface of the frame 3 away from the rear cover 2. After the door and window are opened, the adjusting bolt 6 can be screwed to drive the slider 5 to slide upward, and while the adjusting bolt 6 drives the slider 5 to continue to move, one end of the lever piece 4 is clamped into the clamping groove 7 at one end of the slider 5, so as to limit the lever piece 4 so that the lever piece 4 cannot rotate. When the lever piece 4 cannot rotate, the main rotating arm 15 and the auxiliary rotating arm 11 cannot rotate the upper cover 14 under the action of the limitation of the lever piece 4, so that the door and window remain in the open locked state to avoid accidental closing when the door and window are hit;

[0027] The frame 3 is integrally formed, so that the frame 3 has higher strength and stability, and greatly enhances the load-bearing capacity, so that when the door or window is accidentally closed, the main rotating arm 15 and the auxiliary rotating arm 11 rotate in the frame 3, they can withstand the force of the collision and avoid hinge breakage.
