Description

Technical Field

[0001] This utility model relates to a laser marking instrument, belonging to the technical field of laser marking instruments. Background Technology

[0002] Laser line markers emit vertical or horizontal visible laser light. They are commonly used with laser levels to measure baselines and mark horizontal or vertical lines on target surfaces. Existing laser line markers consist of a housing and a core assembly housed within it, with the laser module mounted on the core assembly. Current laser crosshair markers (cylindrical lens diffusion method) are limited by a small wide-angle projected laser line, uneven brightness, a bright center line, and a gradually dimming trailing line with poor visibility. These limitations prevent traditional laser line markers from meeting the requirements of situations demanding a wide-angle projected line and uniform brightness. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a laser marking instrument.

[0004] To achieve the aforementioned objectives, the present invention adopts the following technical solution: a laser marking instrument, comprising a housing and a mechanism assembly installed within the housing, the mechanism assembly comprising a mechanism support and a mechanism pendulum, the mechanism pendulum being suspended on the mechanism support, and a conical mirror laser module mounted on the mechanism pendulum; characterized in that:

[0005] The conical laser module includes an upper conical laser module and a front conical laser module. The upper conical laser module is installed on the top of the movement body and extends out of the top of the movement support. The front conical laser module is installed on the front side of the bottom of the movement body. The upper conical laser module is used to project vertical lines with a range of greater than 100 degrees and less than 360 degrees, uniform light brightness, and no darkening tail lines. The front conical laser module is used to project horizontal lines with a range of greater than 100 degrees and less than 360 degrees, uniform light brightness, and no darkening tail lines. The projection lines of the upper and front conical laser modules intersect at a cross.

[0006] The top of the movement body is provided with an upper conical laser module mounting base, and the upper conical laser module mounting base is provided with an upper conical laser module mounting through hole. The upper conical laser module mounting through hole is located on the upper side of the movement support, and the hole direction of the upper conical laser module mounting through hole is parallel to the top of the movement support, and the hole direction of the upper conical laser module mounting through hole is perpendicular to the two sides of the movement body; the upper conical laser module is inserted into and installed in the upper conical laser module mounting through hole;

[0007] The bottom front side of the movement body is provided with a front conical laser module mounting base, and the front conical laser module mounting base is provided with a front conical laser module mounting through hole. The hole direction of the front conical laser module mounting through hole is perpendicular to the horizontal direction of the movement bracket. The front conical laser module is inserted into and installed in the front conical laser module mounting through hole, and the laser head of the front conical laser module is located on the top of the front conical laser module mounting base.

[0008] A copper weight is installed at the bottom of the movement's pendulum body.

[0009] The movement body is equipped with a first counterweight screw and a second counterweight screw.

[0010] This utility model has a reasonable and simple structure and is easy to use. Structurally, it includes a shell, a mechanism assembly, a conical laser module, an upper conical laser module, and a front conical laser module, wherein the shell protects the internal components. The mechanism assembly includes a mechanism support and a mechanism swing body, with the swing body suspended on the mechanism support. The conical laser module includes an upper conical laser module and a front conical laser module; the upper conical laser module is installed on the top of the mechanism swing body, and the front conical laser module is installed on the front side of the bottom of the mechanism swing body.

[0011] In terms of projection relationship, the laser lines projected by the upper cone-shaped laser module and the front cone-shaped laser module intersect in a cross shape.

[0012] During installation, the cone-shaped laser module mounting base is located on the top of the mechanism's swing body and has a mounting through hole. The direction of the through hole is parallel to the top of the mechanism's support and perpendicular to both sides of the mechanism's swing body.

[0013] Front cone mirror laser module mounting base: Located on the front side of the bottom of the movement body, it has a mounting through hole, the direction of which is perpendicular to the horizontal direction of the movement bracket.

[0014] Installation of the cone-shaped laser module: Insert the upper cone-shaped laser module and the front cone-shaped laser module into their respective mounting holes.

[0015] Furthermore, a copper counterweight is installed at the bottom of the mechanism's pendulum body to maintain its balance and stability. A first counterweight screw and a second counterweight screw are also installed on the mechanism's pendulum body to fine-tune its center of gravity and ensure the accuracy of laser projection.

[0016] The design of the upper and front conical laser modules ensures uniform light brightness without any darkening trails. It can project horizontal lines greater than 100 degrees and less than 360 degrees, as well as vertical lines greater than 100 degrees and less than 360 degrees, meeting the needs of applications requiring wide-angle projection and uniform brightness to improve overall visibility. The use of a copper weight and counterweight screws ensures the balance and stability of the mechanism's pendulum, improving the accuracy of laser projection.

[0017] The conical mirror laser module is fixed by through-hole mounting, which facilitates assembly and maintenance.

[0018] In summary, the present invention has a conical laser module (an upper conical laser module and a front conical laser module) set at the upper end and the front end of the mechanism pendulum body, respectively. The upper conical laser module projects a plumb bob, and the front conical laser module projects a horizontal line. The projection lines of the upper conical laser module and the front module are set as cross lines.

[0019] The function of the magnetic damping module is to generate a damping effect between the magnetic force and the copper pendulum when the movement body is in a self-diving state, thereby shortening the time of pendulum stop.

[0020] In summary, the laser line marker provided by this utility model, through its unique conical lens laser module design, can project light with uniform brightness and without producing a darkening tail line. It can also project horizontal lines greater than 100 degrees and less than 360 degrees and vertical lines greater than 100 degrees and less than 360 degrees, thus meeting the needs of marking lines requiring a wide-angle projection, uniform brightness, and improved overall visibility of the projected light. This enhances the applicability and measurement accuracy of the laser line marker. Attached Figure Description
