DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0017] Embodiment. A laser receiving type contour ruler, comprising: Figure 1-3 As shown, it includes a contour ruler body 23 and a laser receiver 26 that can be adjusted up and down relative to the contour ruler body 23 and fixed in height. The contour ruler body 23 is provided with a vertically arranged mounting groove 7, and the laser receiver 26 is provided with a claw 8 for cooperating with the mounting groove 7.

[0018] The contour ruler body 23 includes a base 1, a vertically arranged and hollow rear cover 2 is provided on the upper side of the base 1, an opening 4 for mounting a scale plate 3 is provided at the front end of the rear cover 2, a mounting groove 7 is provided on one side of the opening 4 and parallel to the opening 4, and a top cover 6 is provided inside the rear cover 2 for fixing the rear cover 2 and the scale plate 3.

[0019] Limiting grooves 20 corresponding to the openings 4 are provided at both ends of the scale plate 3 .

[0020] The top cover 6 includes a support tube 21 corresponding to the internal shape of the rear cover 2 , and a top plate 22 corresponding to the rear cover 2 and the scale plate 3 is provided on the upper end of the support tube 21 .

[0021] The clamping claw 8 includes a gear portion 11 , a connecting arm 12 corresponding to the mounting slot 7 is provided on one side of the gear portion 11 , and a mounting hole 13 is provided in the gear portion 11 .

[0022] The laser receiver 26 includes a base plate 5, which is provided with a symmetrically arranged mounting shaft 9 corresponding to the mounting hole 13. A guide sleeve 10 corresponding to the mounting shaft 9 is provided on the side of the mounting shaft 9 facing away from the scale plate 3. A trip button 14 is provided in the guide sleeve 10, and a tooth 15 corresponding to the gear part 11 is provided on one side of the trip button 14. A connecting spring 16 is provided between the two groups of trip buttons 14. A main control board 17 is provided on one side of the base plate 5, and a light sensing component 28 is provided on the side of the main control board 17 facing away from the base plate 5. A front cover 18 is provided outside the main control board 17 and the base plate 5. A panel 19 is provided at the front end of the front cover 18. A light-transmitting plate 27 corresponding to the light-sensing component 28 is provided in the panel 19. A buzzer 24 and an indicator light 25 are connected to the main control board 17. The light-transmitting plate 27 can be made of an acrylic plate.

[0023] The working principle of this application is that the existing contour ruler uses light emitted by a laser level to illuminate the contour ruler. The position of the light on the contour ruler is observed to make appropriate adjustments to the height of the floor tiles to achieve the purpose of laying flat. Such a contour ruler does not have a feedback function and cannot provide feedback on the flatness of the tile laying. This application is also used in conjunction with an external laser level. This application realizes laser detection by providing a laser receiver 26. The laser receiver of this application is an improvement on the existing laser receiver, with the addition of a clamping claw 8. The provision of the clamping claw 8 enables the laser receiver 26 to move up and down along the contour ruler body 23, which improves its applicability. When moving the laser receiver 26 relative to the contour scale body 23, the trip button 14 is pressed, causing it to compress the connecting spring 16. As the trip button 14 moves relative to the guide sleeve 10, the teeth 15 on one side of the trip button 14 engage with the gear portion of the pawl 8, causing the pawl 8 to rotate relative to the mounting shaft 9 and separating the connecting arm 12 from the mounting slot 7. This allows the laser receiver 26 to move relative to the contour scale body 23. Furthermore, the laser receiver is provided with a scale to facilitate comparison with the contour scale body. Once the position is determined, releasing the trip button 14 resets the trip button under the action of the connecting spring, causing the pawl 8 to engage with the mounting slot 7, allowing the laser receiver 26 to be installed. The laser receiver can receive laser signals. If the laser signal level is too low or too high, the indicator light 25 illuminates or changes color, and a buzzer is triggered to alert, providing improved reliability. The contour ruler body 23 and the laser receiver are detachable, and if they are damaged, they can be easily replaced and repaired. In addition, the two can be disassembled and used according to construction needs, which improves applicability.
