Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a handle lock and a handle structure thereof. The handle structure comprises a panel provided with an installation through hole, a handle seat and a handle, wherein the handleseat is rotationally installed in the installation through hole; the handle seat extends in the axial direction of the installation through hole; one end of the handle seat is an installation part and the other end of the handle seat is a connection part; the handle comprises a handle body and a sleeve connected with the handle body; the installation part is detachably inserted into the sleeve, wherein any one of the outer wall of the installation part and the inner wall of the sleeve is provided with a convex part, and the other corresponding position is provided with a concave part, and thecorresponding position on the other one of the outer wall of the installation part and the inner wall of the sleeve is provided with a concave part; and the convex part is engaged with the concave part. In the actual use process, even if the handle is subject to great torque, the convex part and the concave part are engaged with each other, and the handle can be prevented from rotating in the circumferential direction relative to the handle seat, so that the probability of the handle loosening is greatly reduced, and the reliability of the handle structure is effectively improved. Therefore,by setting the convex part and the concave part, the handle structure and the handle lock are more reliable.

Description

technical field [0001] The invention relates to the technical field of door and window hardware, in particular to a handle lock and its handle structure. Background technique [0002] With the development of the economy, handle locks, as a relatively common lockset, are used more and more widely, such as being applied to doors and windows of buildings, safe doors, wardrobes, storage boxes, etc. The traditional handle lock includes a handle structure, and the handle structure includes a panel, a handle seat rotatably installed on the panel, and a handle connected with the handle seat in transmission. In practical application, people only need to turn the handle so that the handle is rotated at a certain angle relative to the panel to realize the opening or locking of the door and window. [0003] However, if the torque of turning the handle is too large, the handle is likely to rotate relative to the handle seat, thereby causing the handle to become loose, which greatly affe...
