Referring to fig. 4 to 9, in order to more vividly and accurately describe a partial structure of the two-line laser 100, fig. 7 to 9 are provided, fig. 7 is a perspective view of the partial structure of the two-line laser 100, fig. 8 is another angle view of fig. 7, and fig. 9 is a partial structure view of the horizontal laser and the vertical laser assembled inside the housing. Specifically, the position of the second rotation adjusting screw 42 in fig. 7 and 8 is different from the position of the second rotation adjusting screw 42 in fig. 4, that is, the specific setting positions of the second rotation adjusting screw 42 and the first rotation adjusting screw 41 can be selected according to actual needs, and only the limited range of the second rotation adjusting screw 42 and the first rotation adjusting screw 41 in the following embodiments is required. The adjustment element 40 comprises a rotation adjustment screw comprising a first rotation adjustment screw 41 and a second rotation adjustment screw 42, and a swinging adjustment screw comprising a first swinging adjustment screw 43 and a second swinging adjustment screw 44. Wherein, a pair of the first rotating adjusting screws 41 is used for adjusting the rotation angle of the first surface light emitted by the horizontal laser 31, a pair of the second rotating adjusting screws 42 is used for adjusting the rotation angle of the second surface light emitted by the vertical laser 32, a pair of the first swinging adjusting screws 43 is used for adjusting the pitching swinging angle of the first surface light of the horizontal laser 31, and a pair of the second swinging adjusting screws 44 is used for adjusting the horizontal swinging angle of the second surface light of the vertical laser 32, and the two-line laser 100 can emit surface light to a designated position by respectively adjusting the first rotating adjusting screws 41, the second rotating adjusting screws 42, the first swinging adjusting screws 43 and the second swinging adjusting screws 44.
The laser seat 20 is provided with a first rotation adjusting hole 213 and a second rotation adjusting hole 214 for respectively installing the first rotation adjusting screw 41 and the second rotation adjusting screw 42.
The pair of first rotation adjusting holes 213 are linearly arranged, perpendicular to the central axis of the horizontal laser mounting hole 211, and located on one side of any central axial plane of the horizontal laser 31. The first rotation adjusting holes 213 penetrate through the mounting base 21 from the side surface and communicate with the horizontal laser mounting hole 211, and the two first rotation adjusting holes 213 are respectively located at two sides of the horizontal laser mounting hole 211. The two first rotation adjusting screws 41 are respectively disposed at two ends of the first rotation adjusting hole 213, and can be respectively screwed in or out along the first rotation adjusting hole 213 relative to the mounting base 21, so that one end of the first rotation adjusting screw 41 abuts against the horizontal laser 31 or is separated from the horizontal laser 31, thereby adjusting the rotation angle of the horizontal laser 31.
Preferably, the horizontal laser 31 is provided with two first abutment surfaces 311, the two first abutment surfaces 311 are arranged substantially in line with the first rotation adjusting hole 213, and one first abutment surface 311 corresponds to one end of the first rotation adjusting hole 213, that is, one first abutment surface 311 corresponds to one first rotation adjusting screw 41. One of the first rotation adjusting screws 41 is screwed in the axial direction of the first rotation adjusting hole 213 to abut against a corresponding one of the first abutment surfaces 311. The first contact surface 311 is a groove recessed in the horizontal laser 31, so that the first rotation adjusting screw 41 can easily adjust the rotation angle of the horizontal laser 31 through the groove, thereby maximizing the moment generated by the first rotation adjusting screw 41 on the horizontal laser 31 and preventing slippage between the first rotation adjusting screw 41 and the horizontal laser 32. Referring to fig. 4, in particular, when the central axes of the horizontal laser 31 and the horizontal laser installation hole 211 are coincident, the bottom surface of the groove is located below the first rotation adjusting hole 213, and the bottom surface of the groove is perpendicular to the first rotation adjusting hole 213 by a predetermined distance, so that the first rotation adjusting screw 41 can rotate the horizontal laser 31 within a predetermined angle range. When one of the first rotation adjusting screws 41 rotates the horizontal laser 31 to a limit angle, the bottom surface of the groove abuts against the first rotation adjusting screw 41, so that the first rotation adjusting screw 41 cannot move further in the direction of rotating the horizontal laser 32. It is understood that the preset distance between the bottom surface of the groove and the first rotation adjusting hole 213 may be set as required to correspondingly change the angular range of the rotation of the horizontal laser 31.
The horizontal laser 31 can rotate in a first direction relative to the horizontal laser installation hole 211 by screwing one first rotation adjusting screw 41 along the first rotation adjusting hole 213 to make the first rotation adjusting screw abut against a corresponding first abutting surface 311; the other first rotation adjusting screw 41 is screwed along the first rotation adjusting hole 213 to abut against the other first abutment surface 311, so that the horizontal laser 31 can be rotated in the second direction with respect to the horizontal laser mounting hole 211. The first direction and the second direction are opposite in direction. When the horizontal laser 31 rotates, one of the first rotation adjusting screws 41 is in a separated state from the corresponding one of the first contact surfaces 311, and the other one of the first rotation adjusting screws 41 contacts the corresponding other one of the first contact surfaces 311, so that the horizontal laser 31 rotates. The two first rotation adjusting screws 41 are screwed into the centers of the first rotation adjusting holes 213, so that the two first rotation adjusting screws 41 are respectively abutted against the two first abutting surfaces 311, and at this time, the rotation angle of the horizontal laser 31 is fixed.
When the rotation angle of the horizontal laser 31 is specifically adjusted, one of the first rotation adjusting screws 41 may be first screwed out along the first rotation adjusting hole 213 to keep a certain distance from the corresponding one of the first abutting surfaces 311, and then another one of the first rotation adjusting screws 41 may be screwed into another one of the first rotation adjusting holes 213 to abut against the corresponding another one of the first abutting surfaces 311, and the horizontal laser 31 may abut against another one of the first rotation adjusting holes 213, at this time, since the tail end of the horizontal laser 31 is elastically clamped to the edge of the horizontal laser mounting hole 211 by the elastic clamping member 23, the horizontal laser 31 may rotate around its own central axis under the action of the moment. The horizontal laser 31 can be rotated to a desired angle by repeatedly screwing in or screwing out the two first rotation adjusting screws 41 along the two ends of the first rotation adjusting hole 213, respectively, and finally, the two first rotation adjusting screws 41 are screwed in simultaneously, so that the two first rotation adjusting screws 41 simultaneously abut against the horizontal laser 31, and the horizontal laser 31 is fixed at the desired angle.
The pair of second rotation adjusting holes 214 are linearly arranged, are perpendicular to the central axis of the vertical laser mounting hole 211, and are located on one side of any one of the central axial planes of the vertical laser 32. The second rotation adjusting holes 214 penetrate through the mounting base 21 from the side surface and communicate with the vertical laser mounting holes 212, and the two second rotation adjusting holes 214 are respectively located on two sides of the vertical laser mounting holes 212. The two second rotation adjusting screws 42 are respectively disposed at two ends of the second rotation adjusting hole 214, and can be respectively screwed in or out relative to the mounting base 21 along the second rotation adjusting hole 214, so that one end of the second rotation adjusting screw 42 abuts against the vertical laser 32 or is separated from the vertical laser 32, thereby adjusting the rotation angle of the vertical laser 32.
Preferably, the vertical laser 32 is provided with two second abutting surfaces 321, the two second abutting surfaces 321 are arranged in a substantially straight line with the second rotation adjusting hole 214, and one second abutting surface 321 corresponds to one end of the second rotation adjusting hole 214, that is, one second abutting surface 321 corresponds to one second rotation adjusting screw 42. One of the second rotation adjusting screws 42 is screwed in the axial direction of the second rotation adjusting hole 214 to abut against a corresponding one of the second abutment surfaces 321. The second abutting surface 321 is a groove concavely formed on the vertical laser 32, and the arrangement manner of the groove of the vertical laser 32 is the same as that of the groove of the horizontal laser 31, which is not described herein again.
The principle of adjusting the rotation angle of the vertical laser 32 by the second rotation adjusting screw 42 is the same as the principle of adjusting the horizontal laser 31 by the first rotation adjusting screw 41, and is not described herein again.
The mounting base 21 is provided with a first swing adjusting hole 215 for mounting the first swing adjusting screw 43.
A pair of the first swinging adjusting holes 215 are linearly arranged and horizontally arranged on the mounting base 21, and the first swinging adjusting holes 215 are located on the central axis plane of the horizontal laser 31 and are vertically arranged with respect to the horizontal emitting port 111. The first swing adjusting holes 215 penetrate through the mounting base 21 from the side surface and communicate with the horizontal laser mounting hole 211, and the two first swing adjusting holes 215 are respectively located on two sides of the horizontal laser mounting hole 211. The two first swing adjusting screws 43 are respectively disposed at two ends of the first swing adjusting hole 215, and can be respectively screwed in or out relative to the mounting base 21 along the first swing adjusting hole 215, so that one end of the first swing adjusting screw 43 abuts against the horizontal laser 31 or is separated from the horizontal laser 31, thereby adjusting the pitch swing angle of the horizontal laser 31.
When the pitching oscillation angle of the horizontal laser 31 is specifically adjusted, one of the first oscillation adjusting screws 43 may be first screwed out along the first oscillation adjusting hole 215 to keep a certain distance from one side of the horizontal laser 31, and then another first oscillation adjusting screw 43 may be screwed into the other end of the first oscillation adjusting hole 215 to abut against the other side of the horizontal laser 31 and abut the horizontal laser 31 against the opposite side, at this time, since the tail end of the horizontal laser 31 is elastically clamped to the edge of the horizontal laser mounting hole 211 by the elastic clamping member 23, the horizontal laser 31 is swung to the opposite side under the thrust force. The horizontal laser 31 can be fixed at a desired angle by repeatedly screwing in and out the two first swing adjusting screws 43 along the first swing adjusting holes 215 to swing the horizontal laser 32 to a desired angle, and finally screwing in the two first swing adjusting screws 43 simultaneously to press the two first swing adjusting screws 43 against the horizontal laser 31 simultaneously. In this embodiment, the first surface light of the horizontal laser 31 is emitted perpendicularly to the ground through the horizontal emission port 1121.
A second swing adjusting hole 216 is formed in the mounting base 21, and is used for mounting the second swing adjusting screw 44.
A pair of the second swing adjusting holes 216 are linearly arranged and horizontally arranged in the mounting base 21, and the second swing adjusting holes 216 are located on a central axial plane of the vertical laser 32 and are vertically arranged with respect to the vertical emitting port 112. The second swing adjusting holes 216 penetrate through the mounting base 21 from the side surface and communicate with the vertical laser mounting holes 212, and the two second swing adjusting holes 216 are respectively located on two sides of the vertical laser mounting holes 212. The two second swing adjusting screws 44 are respectively disposed at two ends of the second swing adjusting hole 216, and can be respectively screwed in or out relative to the mounting base 21 along the second swing adjusting hole 216, so that one end of the second swing adjusting screw 44 abuts against the vertical laser 32 or is separated from the vertical laser 32, thereby adjusting the pitch swing angle of the vertical laser 32.
The adjustment principle of the second swing adjustment screw 44 for the swing angle of the vertical laser 32 is the same as that of the first swing adjustment screw 43 for the horizontal laser 31, and is not described herein again. In the present embodiment, the second surface ray of the vertical laser 32 is emitted perpendicularly to the ground opposite to the vertical emission port 112, and the second surface ray intersects with the first surface ray.
It is understood that, in the above embodiment, the two elastic clamping members 23 are respectively sleeved on the tail ends of the horizontal laser 31 and the vertical laser 32, and the first swing adjusting screw 43 and the second swing adjusting hole 216 are respectively arranged on the head ends of the horizontal laser 31 and the vertical laser 32.
