Simpled electronic lock handle reversing structure

Abstract

An electronic lock handle reversing structure comprises a front panel 10 and a handle 20 with a fingerprint sensor, and a front handle head 12 which is inserted through a mounting base 11 and is fixedly connected to the handle, a reset block 13 is provided on a top of the front handle head, and at least one reset spring 14 is provided between the reset block and a side wall of the mounting base. When an unlocking direction of the handle needs to be changed, the handle is directly turned by 180 degrees which moves the reset block, against the bias from the springs, from engagement with the front handle head in a first position into engagement with the front handle head in a second, reversed position. Preferably the mounting base has an arc shaped groove (15 Fig 4) in which a limiting member (17 Fig 3) on the front handle head such that when the handle is rotated to be unlocked the limiting member abuts the end of the groove preventing over rotation.

Description

1. The disclosure pertains to the field of locks, and specifically pertains to an electronic lock handle reversing structure. BACKGROUND 2. During installation of an electronic lock, due to different opening directions of a door, an unlocking direction of a handle of a lock body needs to match the opening direction of the door in order to be unlocked by turning the handle. However, when the handle of the existing electronic lock is reversed, due to a fingerprint head provided on a front surface of the handle and connected to a circuit board through a wire, the handle needs to be disassembled from the lock body to change the direction before being fixed mounted in the lock body. The disassembly and assembly can easily cause the wire to rub back and forth at an edge of a threading hole on the handle, causing damage and wasting labor and time costs. SUMMARY 3. The disclosure solves the problems of waste of labor and time costs due to inconvenient operation of changing an unlocking direction of a handle of an existing lock body. 4. The disclosure adopts the following technical solution: an electronic lock handle reversing structure, comprises a front panel and a handle, a fingerprint head is provided in the handle, a mounting base, a front handle head and a reset block are provided in the front panel, one side of the front handle head inserts through the mounting base and is fixedly connected to the handle, the reset block is provided on a top of the front handle head, and a reset spring is provided between the reset block and a side wall of the mounting base. 5. Further, the mounting base is provided with an arc-shaped groove, a limiting portion is provided in the arc-shaped groove, the front handle head is provided with a protruding limiting member, the limiting member is arranged in the arc-shaped groove, and when the handle is turned to be unlocked, the limiting member abuts against the limiting portion in the arc-shaped groove for limiting. 6. Further, a reset block pressing plate is provided on a surface of the mounting base, and the reset block pressing plate is arranged on a surface of the reset block and is fixedly connected with the mounting base by a connecting component. 7. The disclosure achieves the following beneficial effects compared with the prior art: when an unlocking direction of the handle needs to be changed, the handle is directly turned by 180 degrees to complete reversing of the unlocking direction, avoiding the waste of labor and time costs due to repeated assembly and disassembly of the handle, and reducing damage to the fingerprint head. BRIEF DESCRIPTION OF THE DRAWINGS 8. FIG. 1 is a front view of the disclosure; 9. FIG. 2 is an exploded view of the disclosure; 10. FIG. 3 is an exploded view of a mounting base and a front handle head of the disclosure; 11. FIG. 4 is a structural schematic view of the mounting base of the disclosure; 12. FIG. 5 is a schematic view of movement of a limiting member of the front handle head in the arc-shaped groove of the base of the disclosure; and 13. FIG. 6 is a schematic view of changing an unlocking direction of the handle of the disclosure. 14. Reference numerals: front panel 10, handle 20, fingerprint head 21, mounting base 11, front handle head 12, reset block 13, reset spring 14, arc-shaped groove 15, limiting portion 16, limiting member 17, and reset block pressing plate 18. DESCRIPTION OF THE EMBODIMENTS 15. As shown in FIGS. 1 to 6, an electronic lock handle reversing structure, comprises a front panel 10 and a handle 20, a fingerprint head 21 is provided in the handle 20, a mounting base 11, a front handle head 12 and a reset block 13 are provided in the front panel 10, one side of the front handle head 12 inserts through the mounting base 11 and is fixedly connected to the handle 20, the reset block 13 is provided on a top of the front handle head 12, and a reset spring 14 is provided between the reset block 13 and a side wall of the mounting base 11. 16. When an unlocking direction of the handle 20 needs to be changed, the handle 20 is turned by 180 degrees to change from the original leftward unlocking to rightward unlocking or from the original rightward unlocking to the leftward unlocking. When the handle 20 is turned, the handle 20 drives the front handle head 12 to turn. When the front handle head 12 turns, the reset block 13 is pushed to move upwards, so that the reset spring 14 between the reset block 13 and the side wall of the mounting base 11 retracts. After reversing of the handle 20 is completed, the retracted reset spring 14 is released to push the reset block 13 against the top of the front handle head 12. 17. A surface of the mounting base 11 facing the front handle head 12 is provided with an arc-shaped groove 15, and a limiting portion 16 is provided in the arc-shaped groove 15. A surface of the front handle head 12 facing the mounting base 11 is provided with a protruding limiting member 17, and the limiting member 17 is arranged in the arcshaped groove 15. During use, when the handle 20 is turned to be unlocked, the limiting member 17 abuts against the limiting portion 16 in the arc-shaped groove 15 for limiting. When the unlocking direction of the handle 20 needs to be changed, the limiting member 17 of the front handle head 12 is driven by the handle 20 to move from one side of the arc-shaped groove 15 to the other side of the arc-shaped groove 15. 18. A reset block pressing plate 18 is provided on the surface of the mounting base 11, and the reset block pressing plate 18 is arranged on a surface of the reset block 13 and is fixedly connected with the mounting base 11 by a connecting component, so that the reset block 13 is fixedly mounted in the mounting base 11. 19. In summary, for the electronic lock handle reversing structure of the disclosure, when the unlocking direction of the handle 20 needs to be changed, the handle 20 is directly turned by 180 degrees to complete the reversing of the unlocking direction, avoiding the waste of labor and time costs due to repeated assembly and disassembly of the handle, and reducing damage to the fingerprint head 21.
