Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hardware hinge lock. Background Art

[0002] A hinge is a mechanical device used to connect two solid bodies and allow them to rotate relative to each other. It is generally composed of two components that can rotate relative to each other. Some household cabinets, wardrobes, etc. all require hinges. The hinges can be installed between the cabinet body and the cabinet door, which can provide a buffering function when the cabinet door is closed, reduce the noise caused by the collision between the cabinet door and the cabinet body when closing, and avoid pinching fingers, etc.

[0003] Existing hinges can generally only facilitate the opening and closing of cabinet doors, but cannot lock the cabinet doors. It is also necessary to set special locks on the side or upper and lower ends of the cabinet door away from the hinges to lock the cabinet door and increase safety. However, setting locks on cabinet doors generally takes up a certain space on the cabinet doors. Some cabinet doors also require lock holes and handles to be set on the front of the cabinet doors. When patterns need to be set on the cabinet doors, it is easy to affect the appearance of the cabinet doors. For this reason, we provide a hardware hinge lock to solve the above problems.

[0026] A sloping plate 7 is provided on one side of the movable plate 3, and the cross-sectional shape of the sloping plate 7 is a triangle. When the sloping plate 7 squeezes the block 602, the two blocks 602 can be squeezed into the inside of the fixed box 601. When the sloping plate 7 passes over the block 602, the block 602 can clamp the sloping plate 7 under the action of the first spring 603. At the same time, the sloping plate 7 moves into the groove in the middle of the supporting plate 5, and the stability of the sloping plate 7 is increased by the groove. A rebound mechanism 8 is provided at one end of the sloping plate 7, and an adjusting plate 9 is provided at the end of the rebound mechanism 8 away from the sloping plate 7. The rebound mechanism 8 includes a circular hole 801, and the circular hole 801 is opened inside the movable plate 3. A round rod 802 is slidably connected to the inner wall of the circular hole 801, and one end of the round rod 802 is fixedly connected to a fixed The fixed block 803, a side of the fixed block 803 away from the round rod 802 is fixedly connected to the inclined plate 7, one end of the round rod 802 away from the fixed block 803 is threadedly connected to the adjusting plate 9, the end of the round rod 802 is provided with a thread, the adjusting plate 9 is composed of a pull ring and a cylinder, the round rod 802 is inserted into the inside of the cylinder, and the insertion length of the round rod 802 inside the cylinder can be adjusted by rotating the adjusting plate 9.

When no external force is applied, the second spring 804 can keep the inclined plate 7 in the support plate 5 to prevent the inclined plate 7 from detaching.

[0027] Working principle: During installation, the adjusting plate 9 is screwed off from the end of the round rod 802, and the round rod 802 is pulled out from the round hole 801. The fixed plate 1 is fixed to the inner side of the cabinet body by bolts, and the movable plate 3 is fixed to the inner side of the cabinet door. The cabinet door is drilled at the position of the round rod 802, and then the round rod 802 passes through the round hole 801 and the hole on the cabinet door in sequence, and at the same time, the second spring 804 is squeezed between the fixed block 803 and the movable plate 3 to fix the inclined plate 7. The adjusting plate 9 is screwed to the end of the round rod 802 so that the adjusting plate 9 squeezes the front of the cabinet door and is adjusted according to the thickness of the cabinet door. When the adjusting plate 9 is screwed for more circles, the inclined plate 7 is closer to the movable plate 3, thereby adjusting the position of the inclined plate 7, which is suitable for cabinet doors of different thicknesses and achieves the effect of increasing applicability. The inclined plate 7 is adjusted to the designed position, and when the inclined plate 7 is rotated 90 degrees, it can enter between the two self-locking mechanisms 6.

When the cabinet door is closed, the cabinet door drives the movable plate 3 to rotate, and the movable plate 3 drives the inclined plate 7 to move close to the block 602, so that the inclined plate 7 squeezes the block 602. Under the action of the inclined surface, the two blocks 602 squeeze the first spring 603 upward and downward respectively to move. When the inclined plate 7 passes over the block 602, the first spring 603 drives the block 602 to reset, and the block 602 is stuck, thereby achieving the effect of automatic locking.

[0029] When opening, pull the adjustment plate 9, which drives the inclined plate 7 to move closer to the movable plate 3, so that the inclined plate 7 is pulled out from the supporting plate 5. Under the action of the torsion spring 402, the cabinet door is automatically opened, and there is no need to set a handle on the cabinet door to increase the beauty of the cabinet door surface.
