Description

Technical Field

[0001] The utility model relates to a hinge arm structure, which belongs to hardware products. Background Art

[0002] Hinges are a crucial component of door systems. The hinge arm is the primary component of these systems. These hinges are typically concealed, with a single pivot axis located within the doorframe. These simple hinges are widely used in security doors. Single-axis hinges or hinges, especially concealed hinges, have a limited opening angle and generally cannot reach a full 180-degree angle. Furthermore, the hinge is fixed to the doorframe and cannot be removed. Therefore, developing a concealed hinge arm capable of achieving a full 180-degree opening angle is becoming increasingly important. Summary of the Invention

[0003] Based on the above product defects and requirements, the technical problem to be solved by the present invention is to provide a double-axis hole hinge arm structure, which can increase the opening angle of the hinge or hinge and realize the hinge or hinge opening 180 degrees.

[0004] The following is the technical solution adopted by this utility model:

[0006] The rotating arm A is composed of the rolled shaft hole A, the extended edge A of the rolled shaft hole A, the R bent outer corner A, the straight edge or arc surface, the R bent outer corner B straight surface, the bent outer corner C and the connecting part A from the shaft hole A; the rotating arm B is composed of the rolled shaft hole B, the extended edge B of the rolled shaft hole B, the bent outer corner D, the vertical edge or arc edge, the bent outer corner E and the connecting part B from the shaft hole B.

[0007] The positioning device includes a tubular device body, a compression spring and a positioning steel ball. The tubular device body and the rotating arm A are fixed by welding, riveting or screw connection.

[0008] In addition, the arm structure has the following options:

[0009] Further: the hinged arm structure of the pivot arm A and the pivot arm B connected by screws is in the shape of a pivot arm Ca of an integral structural design, and the integral structural pivot arm Ca is composed of a rolled shaft hole A, an extended edge A of the rolled shaft hole A, an R-bent outer angle A, a straight edge or arc surface, an R-bent outer angle B straight surface, a bent outer angle C, an oblique straight edge, a bent outer angle F, a vertical edge or arc edge a, a bent outer angle D, an extended edge B of the rolled shaft hole B and the rolled shaft hole B from the shaft hole A, and a concave structured space slot A and a space slot B are formed between the shaft hole A and the shaft hole B.

[0011] In summary, the advantage of this hinge or hinge arm is its dual-axis hole structure. The hinge or hinge, through the space slots A and B of the arm, can increase the door leaf's opening angle, even achieving a 180-degree opening. Furthermore, because the arms A and B can be separated, the door leaf and door frame can be easily installed and removed. BRIEF DESCRIPTION OF THE DRAWINGS
