DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0020] like Figure 1-5 The illustrated embodiment of an axis element positioning structure and door lock comprises a handle 1 (preferably a cylindrical handle 1, but not limited to this shape. A detachable panel 15 is provided on one side of the cylindrical handle 1 to facilitate the subsequent installation of internal parts. This is a prior art and is therefore not described in detail) and an axis element 2 partially inserted into the handle 1. A guide groove 3 is provided in the handle 1 at a position corresponding to the axis element 2. A locking piece 4 and a fastener 5 for fixing the locking piece 4 in the guide groove 3 are provided in the guide groove 3. A threaded hole 6 threadedly matched with the fastener 5 is provided in the handle 1. A guide bevel 7 is provided on the inner wall of the guide groove 3. A matching bevel 8 slidingly matched with the guide bevel 7 is provided on the locking piece 4. Tightening the fastener 5 can drive the locking piece 4 to move along the direction of the guide bevel 7 and press the axis element 2.

[0021] A mounting portion 9 is fixed or integrally formed inside the handle 1, and an axial hole 10 for mounting the axial element 2 is provided through the mounting portion 9. The guide groove 3 is opened on the mounting portion 9 and is located above or below the axial hole 10. An opening for installing the locking member 4 is provided on the outer side of the guide groove 3. In this embodiment, the axial element 2 is a square shaft, and the axial hole 10 is a square hole.

[0022] A movable hole 11 is provided between the guide groove 3 and the axial hole 10, the locking member 4 has a positioning protrusion 12 located in the movable hole 11, the matching bevel 8 is provided at one end of the locking member 4 opposite to the positioning protrusion 12, and the guide bevel 7 is provided on the side of the movable groove away from the movable hole 11.

[0023] The threaded hole 6 is formed on the inner wall of the guide groove 3 and is parallel to the shaft element 2 . The locking member 4 is provided with an oblong hole 13 corresponding to the threaded hole 6 . The fastener 5 passes through the oblong hole 13 and is threadedly connected to the threaded hole 6 .

[0024] A positioning sleeve 14 is provided on one side of the locking member 4 opposite to the threaded hole 6. A through hole is provided on the positioning sleeve 14 for the fastener 5 to pass through. The head of the outer end of the fastener 5 can abut against the positioning sleeve 14 to prevent the fastener 5 from being screwed too deep.

[0025] A door lock, comprising the above-mentioned shaft element positioning structure, can be applied to locks such as ecological locks or handle locks.
