Description

Technical Field

[0001] The utility model relates to a novel door opener, in particular to a swing arm type door opener. Background Art

[0002] Currently, most door openers on the market are magnetic or claw-type rebounders with a relatively simple structure, requiring manual resetting and a short service life. Or they are more complicated door openers that are difficult to install and use hydraulic buffering, which is costly. Summary of the invention

[0003] The utility model aims to provide a novel door opener, which adopts a trigger-type driving swing arm to complete the door opening and closing operations, and fully adopts springs as power sources, so that the manufacturing cost is lower.

[0004] The technical solution of the utility model is based on a shell, a swing arm, a swing arm reset spring, a touch rod, a touch rod reset spring, a Thomas lever, a pressure head, a pressure head spring, a trigger, a trigger reset spring, and a lever reset spring, and is characterized in that the trigger touch rod is installed at the left end inside the shell, and the top protrudes out of the shell, the Thomas lever is installed in the shell below the touch rod by a middle hinge, and the bottom of the touch rod is vertically opposite to the left end of the Thomas lever; the trigger is installed in the middle of the shell, the right end of the Thomas lever extends to the bottom of the left end of the trigger, and a slider and a sliding rod are respectively installed at the left and right ends of the top of the trigger through a slide groove, a spring is installed between the slider and the sliding rod, and a convex tooth is raised in the middle of the top of the sliding rod; the tail end of the swing arm is hingedly installed in the shell, the right end is above the trigger, and an inverted Y-shaped bayonet is provided at the bottom of the tail end of the swing arm, and the bayonet of the swing arm and the convex teeth of the sliding rod can engage with each other.

[0005] The top of the touch rod of the utility model is provided with an adjusting nut; when the right end of the Thomas lever is tilted, the trigger can be lifted up to drive the sliding rod to make the convex teeth snap into or slide out of the snap-in opening of the swing arm.

[0006] The touch rod reset spring of the utility model is sleeved on the bottom end of the touch rod, the trigger reset spring is installed on the right end of the trigger, the swing arm tail end is installed with a swing arm reset spring, and the lever reset spring is installed on the bottom of the left end of the Thomas lever.

[0007] The pressure head of the utility model is installed in the shell and above the trigger. A pressure head spring is installed on the top of the pressure head. The bottom of the pressure head is vertically in contact with the top and bottom of the slider of the trigger.

[0008] The utility model discloses a swing arm reset spring which is installed at the tail end of the swing arm in a tilted manner with the left side higher and the right side lower.

[0009] The working principle of the utility model is that when the touch rod is squeezed by external force, it will sink and touch the left end of the Thomas lever. When the right end of the Thomas lever is tilted, it will lift the trigger, and the trigger will move forward, and the sliding rod will move in the opposite direction. The convex teeth on the sliding rod and the Y-shaped bayonet of the swing arm are engaged with each other, and the swing arm is ejected, so as to pop open the cabinet door. When opening the door, it is opened about 20 to 30 degrees. When the cabinet door is opened more than 60 degrees, it can be closed automatically. When the swing arm is opened at an angle less than 30 degrees, it will be pushed back by the rebound force. At this time, the swing arm returns to its original position without manual pushing. From 60 degrees to 30 degrees, it needs human push. After it is less than 30 degrees, it does not need human push and it will close automatically.

[0010] The utility model has the advantages of simple and reasonable structure, low manufacturing cost, the adjusting nut on the top of the touch rod can conveniently adjust the touch door opening force, the door is opened by adopting the mechanical principle and the lever principle, and can be automatically reset, and the service life is longer.
