Description

Technical Field

[0001] This utility model relates to the field of lock picking technology, specifically a peephole lock picking tool. Background Technology

[0002] A peephole unlocking tool is a tool that allows you to unlock a door by extending it through the peephole. It does not damage the door or the lock, enabling non-destructive unlocking. However, existing peephole unlocking tools can only open locks with horizontal door handles. For example, existing patents with publication numbers CN204590825U and CN106437305A require that after extending the unlocking tool through the peephole, a lever or handle applies a downward push to the horizontal door handle, causing it to turn. However, not all locks have horizontal door handles. For example, some smart locks have vertical door handles, which cannot be turned by pressing down on the handle. Instead, the handle can only be turned by flicking it. Existing peephole unlocking tools are difficult to use to flick the handle, making them ineffective for unlocking. Utility Model Content

The vertical section 11, the arc section 12 and the connecting section 13 can be integrated into a single structure and can be formed by bending a single stainless steel rod. The end of the connecting segment 13 away from the arc segment 12 is hinged to the drive rod 2 via the first hinge 61. The end of the drive rod 2 away from the connecting segment 13 is hinged to the connecting rod 3 via the second hinge 62. The end of the connecting rod 3 away from the drive rod 2 is hinged to the pull rod 4 via the third hinge 63. The pull rod 4 is provided with a connecting hook 5, which is hinged to the pull rod 4 via the fourth hinge 64. The fourth hinge 64, the third hinge 63, the second hinge 62, and the first hinge 61 can all be hinge shafts. The axis of the fourth hinge 64 is parallel to the axis of the first hinge 61. The axis of the fourth hinge 64 is perpendicular to the axis of the third hinge 63. The axis of the third hinge 63 is parallel to the axis of the second hinge 62.

[0019] In use, the pull rod 4, connecting rod 3, drive rod 2, and part of the control rod 1 are extended into the room through the peephole on the door. The connecting hook 5 on the pull rod 4 is used to hook the door handle. The arc-shaped section 12 is located inside the peephole. Using the contact part between the arc-shaped section 12 and the door as a fulcrum, lifting the bottom end of the control rod 1 will cause the end of the connecting section 13 away from the arc-shaped section 12 to move down, thereby driving the drive rod 2 to move down. When the drive rod 2 moves down, it can pull the pull rod 4 through the connecting rod 3, so that the door handle can be rotated, which can effectively unlock the door, saving time and effort.

[0020] Preferably, in order to facilitate the operation of the control lever, a handle 14 is provided at the bottom of the vertical section 11, and a secondary handle 15 is provided on the side of the handle 14 near the connecting section 13. The secondary handle 15 is rod-shaped and fixed on the outer wall of the handle 14.

[0021] Preferably, the length of the drive rod 2 is adjustable, which can reduce the space occupied during storage and make it suitable for locks with different installation heights by adjusting the length of the drive rod 2.

[0022] The drive rod 2 can be a telescopic rod with a locking structure. Specifically, the drive rod 2 includes a connecting pipe 21 hinged to the connecting section 13, an adjusting rod 22 hinged to the connecting rod 3, and a locking member 23 for locking the relative position between the connecting pipe 21 and the adjusting rod 22. The connecting pipe 21 is provided with several adjusting holes adapted to the locking member 23. One end of the adjusting rod 22 is inserted into the connecting pipe 21. Both the adjusting rod 22 and the connecting pipe 21 can be made of stainless steel.
