US12760996 - Laser sight device
The patent describes a laser sight device featuring a housing, an inner core, and a fine-tuning spring that allows for precise angle adjustments. The design includes elastic pieces that provide balanced force during adjustments and ensure the inner core resets when the force is removed.
Claim 1
1 . A laser sight device, comprising a laser sight device housing, a laser sight device inner core arranged in the laser sight device housing, and a fine-tuning spring sleeved at an end of the laser sight device inner core; wherein the laser sight device housing is provided with two openings extending from back to front, the two openings being arranged on side walls of the laser sight device housing perpendicular to each other, and the laser sight device housing is provided with a limit hole on a side wall of a rear end of the laser sight device housing; the fine-tuning spring comprises a first arc-shaped elastic piece, a second arc-shaped elastic piece, and a protrusion, the first arc-shaped elastic piece and the second arc-shaped elastic piece are respectively inserted into the laser sight device housing from corresponding openings, and the protrusion is inserted into the limit hole; the first arc-shaped elastic piece and the second arc-shaped elastic piece are both provided with spherical protrusions on inner sides of top surfaces thereof, and the spherical protrusions are configured to abut on a front end of the laser sight device inner core; and the first arc-shaped elastic piece and the second arc-shaped elastic piece are configured to cause a continuous and balanced force on the laser sight device inner core when adjusting an angle of the laser sight device inner core, and to reset the laser sight device inner core when the force is withdrawn. the laser sight device housing is provided with two openings extending from back to front, the two openings being arranged on side walls of the laser sight device housing perpendicular to each other, and the laser sight device housing is provided with a limit hole on a side wall of a rear end of the laser sight device housing; the fine-tuning spring comprises a first arc-shaped elastic piece, a second arc-shaped elastic piece, and a protrusion, the first arc-shaped elastic piece and the second arc-shaped elastic piece are respectively inserted into the laser sight device housing from corresponding openings, and the protrusion is inserted into the limit hole; the first arc-shaped elastic piece and the second arc-shaped elastic piece are both provided with spherical protrusions on inner sides of top surfaces thereof, and the spherical protrusions are configured to abut on a front end of the laser sight device inner core; and the first arc-shaped elastic piece and the second arc-shaped elastic piece are configured to cause a continuous and balanced force on the laser sight device inner core when adjusting an angle of the laser sight device inner core, and to reset the laser sight device inner core when the force is withdrawn.
