[0032] The utility model provides an adjustable laser ruler.

[0033] Reference Figures 1 to 6 In this embodiment, the adjustable laser ruler comprises:

[0034] The housing 1 is provided with a mounting groove 13 extending along the length direction of the housing 1;

[0035] The laser emitter 2 is arranged in the mounting groove 13, and a plurality of laser emitters 2 are provided; the plurality of laser emitters 2 are arranged side by side along the length extension direction of the mounting groove 13, and can slide along the mounting groove 13; a light-transmitting port 111 is provided at the front end of the housing 1 so that the laser can be emitted from the light-transmitting port 111.

[0036] Optionally, in this embodiment, the adjustable laser ruler includes a housing 1 and a laser emitter 2. The housing 1 is provided with a mounting groove 13 extending along the length. A plurality of laser emitters 2 are arranged side by side in the mounting groove 13 and can slide along the mounting groove 13. Through the slidable arrangement of the plurality of laser emitters 2, when writing calligraphy or painting outdoors, the user can adjust the spacing of the lasers according to his own needs to form a plurality of light beams with different spacings. Compared with the laser ruler in the prior art, the laser emitters 2 do not need to fill the mounting groove 13. A few laser emitters 2 can achieve the change of spacing by manual adjustment. The device has a simple structure and is easy to manufacture. One of the adjustable laser rulers can only use lasers to print rows or columns. When the user needs to write a grid, two adjustable laser rulers of the present invention are placed vertically to each other, so that the vertical laser and the horizontal laser can intersect to realize the gridding of the paper, and the size of the grid can be adjusted by adjusting the spacing between the laser emitters 2.

[0037] Furthermore, in this embodiment, the inner wall of the shell 1 is also provided with two magnets 15, and the two magnets 15 are respectively arranged at the two ends of the inner wall of the shell 1. When the writer needs rows or columns of angles, multiple laser rulers can be connected together through the magnets 15 to achieve the addition of rows or columns. The combination of multiple laser rulers is convenient for assisting users to create large-scale works, and the use of magnets 15 for connection also makes the connection and disassembly of two adjacent laser rulers more flexible.

[0038] In this embodiment, the shell 1 includes a front cover 11 and a cavity 12, and the front cover 11 and the cavity 12 are detachably connected, and can be connected by a snap connection or a bolt connection, which is not limited here, so as to facilitate the rapid installation and removal of the laser emitter 2, and also facilitate the subsequent maintenance of the internal device; a movable groove 14 is formed on the front cover 11 and the cavity 12, and the laser emitter 2 is partially exposed outside the movable groove 14, that is, the upper end of the laser emitter 2 is exposed outside the movable groove 14, so that when the laser spacing needs to be adjusted, the laser emitter 2 can be moved directly at the upper end of the shell 1 to adjust the spacing, and there is no need to open the shell 1 and then adjust the laser emitter 2, so that the adjustment of the beam spacing is more convenient and quick. A coordinate scale is provided above the light-transmitting port 111. According to the coordinate scale at the upper end of the housing 1, the user can make precise length and spacing adjustments according to the coordinate scale as required, wherein the length of the coordinate scale matches the length of the light-transmitting port 111, and the maximum spacing of the laser beam is the length of the light-transmitting port 111. The length of the coordinate scale is consistent with the length of the light-transmitting port 111, which is convenient for processing and saves more materials and costs. The accuracy of the coordinate scale is set according to requirements to make the measurement accuracy as accurate as possible; wherein the height at which the laser emitter 2 emits the laser should be lower than the height of the light-transmitting port 111 to prevent the light-transmitting port 111 from blocking the emission of part of the laser, resulting in low beam brightness.

[0039] In this embodiment, a control switch 21 is provided at the upper end of the laser emitter 2, wherein the control switch 21 is electrically connected to the laser emitter 2 and is used to control the opening and closing of the laser. The control switch 21 is exposed outside the movable slot 14, which is convenient for the operator to press and operate. Furthermore, in this embodiment, a protrusion structure is integrally formed at the upper end of the control switch 21, and the protrusion structure is convenient for the user to turn the laser emitter 2, thereby conveniently adjusting the spacing of the laser beam. In other embodiments, an indicator light is also provided at the upper end of the laser emitter 2, and the indicator light is electrically connected to the control switch 21 and the laser emitter 2, and can be used to display the opening and closing state of the laser emitter 2. When the laser emitter 2 is turned on, the indicator light is on, and when the emitter is turned off, the indicator light is off, which is convenient for the operator to observe and detect the state of the laser emitter 2. Further, in the present embodiment, the laser emitter 2 further comprises a light module slider 23 and a laser emitting device 22, wherein the light module slider 23 is slidably connected to the guide rail 3, and the laser emitting device 22 is connected to the light module slider 23; the light module slider 23 comprises a linear sliding bearing 231, wherein the battery 9 is electrically connected to the guide rail 3, i.e. the guide rail 3 is conductive, and the linear sliding bearing 231 is slidably connected to the guide rail 3, and the linear sliding bearing 231 is in contact with the guide rail 3, so that the linear sliding bearing 231 is also conductive; wherein the linear sliding bearing 231 is connected to the laser emitting device 22 through a spring, and when the control switch 21 is pressed, the spring is pressed downward, and the spring is in contact with the laser emitting device 22, i.e. the linear sliding bearing 231 is electrically connected to the laser emitting device 22 through the spring, and the laser emitting device 22 emits a laser, and when the control switch 21 is pressed again, the spring returns to its original position, the connection between the linear sliding bearing 231 and the laser emitting device 22 is disconnected, the laser emitting device 22 is powered off, and the laser is turned off.

[0040] In this embodiment, a guide rail 3 is provided in the installation groove 13. A plurality of guide rails 3 are provided and are parallel to each other. The plurality of guide rails 3 are provided through the laser emitter 2, and the laser emitter 2 can reciprocate along the extension direction of the guide rail 3 to adjust the spacing of the light beam. Furthermore, two guide rails 3 are provided, and the two guide rails 3 can limit the rotation of the laser emitter 2, so that the laser emitter 2 can only move along the guide rails 3. The two guide rails 3 save materials and are convenient for installation. Furthermore, a circuit board 4 is provided in the shell 1, and the circuit board 4 is parallel to the rear side of the laser emitter 2, and the circuit board 4 is bolted to the inner wall of the front cover 11. The two guide rails 3 can limit the rotation of the laser emitter 2, but long-term movement of the laser emitter 2 may cause the guide rails 3 to bend and shift. Through the arrangement of the circuit board 4, part of the external force acts on the circuit board 4, reducing the degree of deviation of the guide rails 3, and the replacement of the circuit board 4 is more convenient than that of the guide rails 3. Through the arrangement of the circuit board 4, the deviation of the guide rails 3 is reduced, and the stability of the device is further enhanced.

[0041] In other embodiments, the connection between the guide rail 3 and the laser emitter 2 may be unstable, that is, after the spacing between the laser emitters 2 is adjusted, they will still slide on the guide rail 3 under the action of external force, resulting in errors and changes in the beam spacing. A clamping device can be set between the guide rail 3 and the laser emitter 2. After the beam spacing is adjusted, the position between the laser emitter 2 and the guide rail 3 is fixed and kept stable by the clamping device, preventing the external environment and external forces from causing errors in the adjustment of the beam spacing, which may affect the operator.

[0042] In other embodiments, a slide rail extending along the length direction of the installation groove 13 may also be provided in the installation groove 13. The lower end of the laser emitter 2 is slidably connected to the slide rail, and the laser beam spacing can also be adjusted. The slide rail and the inner wall of the installation groove 13 can be integrally formed for easy processing. Compared with the setting of the guide rail 3, the setting of the slide rail makes installation simple and convenient.

[0043] In this embodiment, a power display device 5 is also provided in the mounting groove 13, and the power display device 5 is electrically connected to the guide rail 3 and the laser emitter 2, wherein a special power supply device is provided in the mounting groove 13 to supply power to the laser emitter 2, and the power supply device supplies power to the laser emitter 2 through the guide rail 3, and the power display device 5 is used to display the remaining power of the power supply device, and the display screen of the power display device 5 is exposed outside the shell 1, reminding the user to charge or replace the power supply device, wherein the power display device 5 is not only used to display the power, but also to display the brightness and light mode, which is convenient for subsequent adjustment, wherein a charging interface 6 is provided on the side of the shell 1, and the charging interface 6 is connected to the power supply device to connect to an external power source to charge the power supply device, without replacing the power supply device, so as to better meet the use requirements. A dust cover 112 is also provided on the outside of the power display device 5, and the dust cover 112 is provided on the power display device 5 to prevent external dust or moisture from entering the device and affecting the operation and service life of the device. Furthermore, the power display device 5 and the charging interface 6 are both connected to the circuit board 4 , a battery 9 is provided at the bottom end of the shell, and the circuit board 4 is connected to the battery 9 .

[0044] Furthermore, in this embodiment, a touch master switch 7 and a light source brightness adjustment switch 8 are provided at the upper end of the cavity 12, wherein the touch master switch 7 is electrically connected to all laser emitters 2. When the user has finished writing, the master switch 7 can be pressed to turn off all laser emitters 2 at the same time, without the need to turn off the laser emitters 2 one by one, which is convenient and quick to operate; the light source brightness adjustment switch 8 is used to adjust the brightness of the light beam emitted by the laser emitter, which is convenient for the user to adjust the brightness of the light beam emitted by the ruler. A touch circuit board is provided at the bottom of the touch master switch 7 and the light source brightness adjustment switch 8, and the charging interface 6 is also connected to the touch circuit board.

[0045] In this embodiment, the light-transmitting port 111 is covered with a dust cover 112, wherein the dust cover 112 is fitted to the inner side of the light-transmitting port 111, and the dust cover 112 is located between the light-transmitting port 111 and the laser emitter 2. The dust cover 112 is fitted to prevent external moisture or dust from entering the interior of the ruler, causing damage and pollution to internal components such as the laser emitter 2 and the guide rail, thereby reducing the service life of the ruler. After a period of use, if the dust cover 112 is blurred or damaged, the shell 1 can be disassembled and the dust cover 112 can be replaced.
