Description

Technical Field

[0001] The utility model relates to a laser marking instrument window rotating device, belonging to the technical field of laser marking instrument design. Background Art

[0002] Laser marking instruments, also known as laser level and vertical instruments or laser projection instruments, can emit vertical or horizontal visible lasers. They are more common in engineering construction and are mainly used to mark horizontal or vertical lines on the target surface. The current laser marking instruments are all structurally provided with a laser window, a window cover on the laser window, a number of light outlets on the window cover, glass installed on the light outlets, and the part of the window cover between the light outlets forms a window column; the laser head extends the laser window and the window cover from the body of the laser marking instrument in sequence. When in use, the laser emitted by the laser head passes through the glass on the light outlet. The part of the window cover between the light outlets forms a window column. Affected by the obstruction of the window column, when the laser line is transmitted to the target surface, the laser projection line transmitted to the target surface must have a breakpoint, resulting in discontinuity of the laser projection line, affecting the user's use, especially when the position of the breakpoint is exactly the position where the user needs to work, so it will cause a certain working error in the actual work, affecting the measurement and marking accuracy.

[0009] The number of the light outlets is 4.

[0010] An upper sealing gasket and a lower sealing gasket are also provided; the upper sealing gasket is arranged between the inner wall at the top of the rotating window cover and the top of the window glass; the lower sealing gasket is arranged between the bottom of the window glass and the base.

[0011] The bottom of the base is fixed to the window of the laser marking instrument, and the rotating window cover is rotated, and the rotating window cover and the rotating pressing plate rotate differently on the base.

[0014] The utility model has a reasonable structure. Through the utility model, when in use: the laser emitted by the laser head passes through the glass on the light outlet. When the light outlet and the window column of the light outlet affect the laser projection line transmitted to the target surface and the laser projection line has a breakpoint, the window cover can be rotated, and the rotating window cover and the rotating pressure plate rotate synchronously on the base. When the rotating window cover rotates, the window column on the rotating window cover is driven to move, so that the breakpoint of the laser projection line transmitted to the target surface can be moved to another place, which is convenient for measuring, marking and working at the previously existing breakpoint, thereby avoiding work errors generated in actual work.

[0015] The utility model device is suitable for the projection window of the laser marking instrument, and the rotating device eliminates the blind area where the laser projection light is broken and fixed. In the utility model, the base is fixed to the existing laser marking instrument window, and the sealing ring is used to eliminate the matching gap between the base and the laser marking instrument window to play a sealing and dustproof role. The rotating window cover and the rotating pressure plate can be used as a 360-degree rotating component.

[0016] Through the utility model, the user can conveniently adjust the position of the interruption point of the laser projection line, which can effectively reduce the error and improve the accuracy, and has great market application and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
