Technical Field

[0001] This invention relates to the field of measuring tools, specifically to a laser instrument capable of projecting lines, marking points, and measuring distances. Background Technology

[0002] Currently, there are levels on the market for projecting horizontal lines and laser rangefinders for measuring object distances, but there are no technical solutions for the needs of projecting lines at arbitrary angles, marking horizontal points at arbitrary distances, and leveling at specific distances. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a laser instrument capable of line projection, point marking, and distance measurement, enabling functions that cannot be achieved by existing technologies, such as distance measurement, line projection at arbitrary angles, point horizontal marking at arbitrary distances, and distance leveling.

[0004] This invention provides a laser instrument capable of projecting lines, marking points, and measuring distances.

[0005] The device includes a housing assembly, a line-projecting laser head and a range-measuring laser head arranged side by side at the front end of the housing assembly, an angle sensor placed inside the housing assembly, a display screen on the surface of the housing assembly, and a circuit board placed inside the housing assembly. The line-projecting laser head, the range-measuring laser head, the angle sensor, and the display screen are all electrically connected to the circuit board.

[0006] Furthermore, a battery is provided inside the housing assembly, and the battery is electrically connected to the circuit board.

[0007] Furthermore, the battery is a rechargeable battery, and the housing assembly is provided with a charging interface mounted on the circuit board.

[0008] Furthermore, the housing assembly is provided with control buttons mounted on the circuit board.

[0009] Furthermore, the buttons include a main button and a function selection button.

[0010] Furthermore, the laser head is mounted on a laser head bracket, and the lower part of the laser head bracket is mounted on the housing assembly via a pivot. One side of the housing assembly is provided with a self-rebound elastic element supporting the rear end of the laser head bracket. The rear end of the laser head bracket is provided with an adjustment seat. The upper side of the adjustment seat is provided with an adjustment slope that is higher on the side closer to the self-rebound elastic element and lower on the side farther from the self-rebound elastic element. The adjustment seat is provided with a strip-shaped hole that passes through the upper and lower sides of the adjustment seat and extends laterally.

[0012] Furthermore, the laser head support adopts a C-shaped clamp structure.

[0013] The beneficial effects of this invention are as follows: By arranging a line-projecting laser head and a distance-measuring laser head side by side at the same end of the housing assembly, the laser instrument can simultaneously project a line using the line-projecting laser head, measure distance using the distance-measuring laser head, and measure the angle of the projected line in real time using an angle sensor.

Detailed Implementation

[0022] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0024] like Figures 1-4 As shown, this embodiment of the invention provides a laser instrument capable of projecting lines, marking points, and measuring distances. It includes a housing assembly 100, a line-projecting laser head 200 and a distance-measuring laser head 300 arranged side by side at the front end of the housing assembly 100, an angle sensor 400 placed inside the housing assembly 100, a display screen 500 disposed on the surface of the housing assembly 100, and a circuit board 600 placed inside the housing assembly 100. The line-projecting laser head 200, the distance-measuring laser head 300, the angle sensor 400, and the display screen 500 are all electrically connected to the circuit board 600.

[0025] This application, by arranging a line-projection laser head 200 and a distance-measuring laser head 300 side-by-side at the same end of the housing assembly 100, allows for simultaneous line projection via the line-projection laser head 200 and distance measurement via the distance-measuring laser head 300. Furthermore, the angle sensor 400 can measure the angle of the projected line in real time. This enables the laser instrument to achieve distance measurement, projection of a laser line at a corresponding angle under real-time angle display, and real-time line projection under real-time distance display. Consequently, the accuracy and efficiency of line projection and distance measurement are greatly improved. It can achieve functions that cannot be realized by existing technologies, such as distance measurement, line projection at any angle, horizontal marking at any distance, and finding a specific distance.

[0026] In practical use, the side of the laser instrument a can be attached to the wall b, the laser head 200 emits a laser line and projects it onto the wall b, and the laser instrument a can be rotated on the wall b to achieve projection at any angle. At the same time, the projection angle can be displayed on the display screen 500.

[0027] like Figure 5As shown, when making a horizontal mark at any distance, rotate the laser instrument a so that it projects a horizontal line c onto the wall b. Then, move the laser instrument a horizontally on the wall b so that the horizontal line c projected by the laser instrument a passes through the target point d. If the target point d protrudes from the wall b, the distance between the laser instrument a and the target point d can be directly measured by the ranging laser head 300. Then, move the laser instrument a horizontally on the wall b to achieve a horizontal mark at any distance. If the target point is a concave hole, it is necessary to use measuring tools such as a tape measure to measure a point on the horizontal line that is at any distance from the target point d. This also achieves a horizontal mark at any distance.

[0028] like Figure 6 As shown, the principle of leveling at a specific distance is basically the same as that of leveling at a fixed point at an arbitrary distance. The difference is that leveling at a specific distance first determines the horizontal distance between the vertical side of the obstacle e (e.g., a decorative painting) and the laser instrument a as a specific distance. Then, the laser instrument a is moved up and down so that the horizontal line c projected by the laser instrument a on the wall b passes through the target point d on the obstacle.

[0029] In one embodiment, such as Figure 4 As shown, a battery 700 is housed within the housing assembly 100. The battery 700 is electrically connected to the circuit board 600 to power the laser instrument. Preferably, the battery 700 is a rechargeable battery, and the housing assembly 100 is provided with a charging interface 800 mounted on the circuit board 600 to charge the rechargeable battery 700.

[0030] In one embodiment, Figure 4 As shown, the housing assembly 100 is provided with control buttons mounted on the circuit board 600, specifically including a main button 910 and a function selection button 920.

[0031] In one embodiment, such as Figure 3 and Figure 4As shown, a line laser head 200 is mounted on a line laser head bracket 210. The lower part of the line laser head bracket 210 is mounted on a housing assembly 100 via a pivot 220. A self-rebound elastic element 230 is provided on one side of the housing assembly 100 to support the rear end of the line laser head bracket 210. An adjustment seat 240 is provided at the rear end of the line laser head bracket 210. An adjustment slope 241 is provided on the upper side of the adjustment seat 240, which is higher on the side closer to the self-rebound elastic element 230 and lower on the side farther away from the self-rebound elastic element 230. A strip hole 242 is provided on the adjustment seat 240, which passes through the upper and lower sides of the adjustment seat 240 and extends laterally. A support seat 250 is provided on the housing assembly 100 below the adjustment seat 240. An adjustment screw 260 passes through the strip hole 242 and is threadedly connected to the support seat 250. One side of the head 261 of the adjustment screw 260 abuts against the adjustment slope 241. With the above structure, when the adjusting screw 260 is tightened downwards, the head 261 of the screw pushes the adjusting seat 240 towards the self-rebound elastic member 230 through the adjusting inclined surface 241 on the adjusting seat 240, causing the rear part of the laser head support 210 to swing towards the self-rebound elastic member 230, thereby achieving clockwise rotation adjustment of the laser head 200. When the adjusting screw 260 is loosened upwards, the self-rebound elastic member 230 pushes the adjusting seat 240 away from the self-rebound elastic member 230 under its own elastic force, causing the rear part of the laser head support 210 to swing away from the self-rebound elastic member 230, thereby achieving counterclockwise rotation adjustment of the laser head 200. Therefore, this application can finely adjust the axial direction of the laser head 200 by tightening or loosening the adjusting screw 260, and can quickly and accurately calibrate the horizontality of the laser head 200.

[0032] Preferably, the rotating shaft 220 is composed of multiple claws 221 spaced apart on the same circumference. The housing assembly 100 has a rotating shaft mounting hole 270, and the mounting hole 270 contains an annular groove 271 that engages with the claws 221 of the rotating shaft 220. When installing the laser head bracket 210, the claws 221 on the rotating shaft 220 are simply inserted into the rotating shaft mounting hole 270 on the housing assembly 100, making installation convenient and quick. The laser head bracket 210 adopts a C-shaped retaining structure; when the laser head 200 is combined with the laser head bracket 210, the laser head 200 is simply inserted into the C-shaped retaining structure.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
