[0019]

Please also refer to Fig. 1 and Fig. 2, which is an exploded view of the handle structure of the present invention, and Fig. 2 is a schematic view of the first embodiment of the handle structure of the present invention. As can be seen from the figure, the handle structure 100 is mounted in a door lock to drive the door latch assembly, allowing the user to conveniently rotate and open the door leaf for access. The handle structure 100 includes a handle 10, a positioning plate 20 and an elastic return member 30. The handle 10 includes a rotating shaft 11 and a grip portion 12 , and the rotating shaft 11 is coupled to the grip portion 12 . In practice, the grip portion 12 is in the form of a rod-shaped handle or a round handle.

[0020]

The positioning plate 20 includes two limiting slots 21, a flange 22 and a coupling hole 23, wherein the limiting slot 21 is symmetrically disposed on the two sides of the positioning plate 20 with the flange 22 as a reference, and the length of the limiting slot 21 Then it is close to the angle at which the handle 10 can rotate to achieve the effect of the limit. Furthermore, the coupling hole 23 is disposed at the center of the positioning plate 20, and has two latching portions 231 for facilitating the engagement of the rotating shaft 11. When the rotating shaft 11 rotates, the positioning plate 20 can be rotated.

[0021]

The elastic returning member 30 and the positioning plate 20 are fastened to the rotating shaft 11 by a buckle assembly 40 to avoid loosening during operation. In practice, the buckle assembly 40 can be buckled on the rotating shaft by using a common C-shaped buckle. The snap groove of the 11 is used to limit the relative position of the elastic return member 30 and the positioning plate 20.

[0022]

The elastic returning member 30 has two abutting portions 301. The abutting portion 301 is placed on both sides of the flange 22 of the positioning plate 20 during installation, and the abutting portion 301 is adjusted according to the required rotation angle of the handle 10. Relative position. In practice, the elastic returning member 30 can be a torsion spring. When the handle 10 is excessively rotated, the elastic returning member 30 utilizes its own elasticity and rigidity to prevent the handle 10 from continuing to rotate, so as to achieve the effect of the limit stop, and thus the original The block components are simplified.

[0023]

When the handle 10 is rotated, the flange 22 of the positioning plate 20 can press the elastic returning member 30 against the abutting portion 301 of the elastic returning member 30 in the rotational direction to store the elastic restoring force, and synchronously actuate the latch assembly. Retract into the door lock to open the door leaf. When the user releases the handle 10, the elastic return member 30 releases the stored restoring force to return the handle 10 to the home position, and also resets the door latch assembly to the actuating position for the purpose of returning the handle structure 100.

[0024]

Please refer to FIG. 3, which is a schematic view of a second embodiment of the handle structure of the present invention. As can be seen from the figure, the operating direction of the handle 10 of the second embodiment is different from that of the first embodiment, and the mounting manner of the positioning plate 20 is correspondingly adjusted according to the direction in which the handle 10 is actuated. In practice, the handle structure 100 can further include the block unit 50. When the block unit 50 is matched with the limiting slot 21 of the positioning plate 20, the rotation angle of the handle 10 can be further restricted to avoid excessive twisting of the elastic return member 30. The fatigue damage of the elastic return member 30 is caused, resulting in a device failure problem.
