Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy shell die-castings for pull-arm door openers, in particular to an aluminum alloy shell die-casting for pull-arm door openers. Background Art

[0002] The arm door opener is a device used in the automatic door system. Its working principle is to use an electric motor or a pneumatic motor to drive one or more arm pulls to open or close the door. During its installation, it needs to be installed inside the aluminum alloy shell die-casting for protection. However, the existing aluminum alloy shell die-casting of the arm door opener still has certain defects when used, such as;

[0003] For example, a pull-arm type electric horizontal switch mechanical lock with publication number CN206000290U fixes the moving bracket seat on the door frame, and the electric door opener pushes and pulls the bracket plate to slide on the moving bracket seat, the bracket plate drives the brake belt, and the brake belt drives the bolt to rise and retract. Since one end of the bolt spring is fixed to the bolt seat, the other end of the bolt spring is sleeved in the small diameter step of the bolt, and the manual release L-shaped component is fixed in the middle groove of the bolt seat by using a fixing pin, and the bolt seat is fixed on the door head column. When the electric door opener opens the door, the bolt retracts in the bolt seat, and the striker pin is stuck in the bolt under the action of the striker pin spring; when the electric door opener closes the door, the striker pin touches the other door body, releasing the bolt to rise in the bolt seat and be bolted to the other door body or the ground.

[0004] However, the arm-type electric flat switch mechanical lock still has the following disadvantages in actual use:

[0005] By fixing the arm rod on a motion bracket seat for installation, in actual use, a larger motion bracket seat needs to be set up for connection, which requires a larger installation space as a whole. Therefore, it may be limited by the door frame structure, thereby affecting the door opening speed and force, making the overall door opening operation inconvenient, and when installed on a motion bracket seat, the outer side of the arm rod cannot be protected, making the outer side of the arm rod susceptible to collision, wear or other damage by external objects, thereby affecting its normal operation and reducing the durability and life of the arm rod.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original aluminum alloy shell die-casting of the arm door opener. Therefore, we proposed that the aluminum alloy shell die-casting of the arm door opener can solve the above problems well. Utility Model Content
