Problems solved by technology

[0003] Because the operating environment of the line throwing instrument is relatively harsh and the dust is relatively large, during the use of the above-mentioned laser line throwing instrument, the bearing that hangs the gravity hammer will enter the dust, resulting in increased friction, and the gravity hammer cannot accurately reach the horizontal position. lasers tend to have bias
Secondly, the gravity hammer of the existing line throwing instrument is often surr

Embodiment Construction

[0020] Below, in conjunction with accompanying drawing and specific embodiment, the invention is described in further detail:

[0021] refer to Figure 1-3 As shown, the laser line throwing instrument in this embodiment includes a base 1 and a rotating base 21 rotatably connected to the base 1 , and the rotating base 21 is arranged parallel to the base 1 . Manually rotate the rotating seat 21 to realize the rough adjustment of the line-throwing position, and then use the screw nut knob 9 to realize the precise adjustment of the line-throwing position. The base 1 includes an adjustment component, which can adjust the angle between the base 1 and the horizontal plane to ensure that the base 1 is parallel to the horizontal plane or forms a certain angle in a certain direction. The casing (not shown) that is connected with the swivel base 21 is provided with a battery compartment 23, and a power supply such as a lithium battery can be placed in the battery compartment 23 to provi...

Abstract

The invention discloses a laser demarcation device, which comprises a base, a battery bin, a shell, a laser window located on the shell, a supporting seat located in the shell, a laser head, a controller, a display unit and a switch, wherein the supporting seat is arranged on a rotating seat, the laser head, the controller and the switch are arranged on the supporting seat, the controller comprises an inclination angle sensor, at least one measuring axis of the inclination angle sensor is parallel to at least one laser ray emitted by the laser head, and the base is an angle-adjustable base. According to the demarcation device, the assembly process is simplified, the production cost is greatly saved, and the function of projecting oblique lines can be achieved.

Description

[technical field] [0001] The invention relates to a line throwing instrument, in particular to a laser line throwing instrument. [Background technique] [0002] In the process of construction and decoration, in order to perform leveling and / or marking, it is often necessary to set a horizontal or vertical datum line as a reference. The laser line instrument has been widely used instead of traditional ink cartridges, plumb weights and other tools. The existing line throwing instruments basically use the gravity hammer for horizontal and vertical laser projection. The laser head is set on the gravity hammer, and the gravity hammer is supported on the hinged frame through the bearing. Throws a horizontal or vertical laser line when the Gravity Hammer is in a plumb position. [0003] Because the operating environment of the line throwing instrument is relatively harsh and the dust is relatively large, during the use of the above-mentioned laser line throwing instrument, the be...
