[0002] During the decoration and construction process, measuring instruments are the core tools to ensure construction accuracy and quality. They can accurately measure key parameters such as the size, angle, levelness and verticality of a space. Among them, panoramic laser scanners, as an advanced measuring device, are widely used in decoration and construction, architectural surveying, cultural relic protection and industrial inspection. Utilizing a laser emission and reception system, combined with a panoramic camera and multiple sensors, it can quickly complete an all-round scan of an object or space and generate a high-precision three-dimensional point cloud model, thereby providing comprehensive and accurate spatial data support for construction.

[0003] When using a panoramic laser scanner, to ensure the accuracy and reliability of the scanned data, the scanner must be kept level. The usual procedure is to firmly mount the scanner on a tripod and secure it by matching the screws on the bottom of the tripod with the screw holes of the scanner, and then perform leveling. However, when performing multi-point scanning or moving scans, the flatness of the ground directly affects the levelness of the scanner. Therefore, leveling needs to be re-calibrated after each movement. Traditional calibration methods require extensive experience and a lot of time, making them unsuitable for multi-point scanning. Therefore, to address the above problems, a measuring instrument for decoration and construction is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] A measuring instrument used in decoration construction includes a surface scanning measuring instrument 1 and a tripod 6. A leveling component 2 is fixedly connected to the bottom of the surface scanning measuring instrument 1. A counterweight component 3 is fixedly connected to the bottom of the leveling component 2 by bolts. A load-bearing component 4 is installed on the outside of the leveling component 2, and a fixing component 5 is installed on the inside of the load-bearing component 4. The leveling component 2 includes a housing 21, and a fixing groove 22 is formed on the inside of the housing 21. The inside of the fixing groove 22 is fixedly connected to the housing of a servo motor 23. The servo motor 23 has a support column 24 fixedly connected to the end of its spindle. The bottom of the housing 21 has a ball 26, an extension rod 27 and a first flange 28 fixedly connected in sequence. The load-bearing component 4 includes a base 41. A folded plate 42 is fixedly connected to the top of the base 41. A ball-supporting ring 43 is fixedly connected to one side of the folded plate 42. A first ball groove 44 is opened on the inner side of the ball-supporting ring 43. A guide hole 45 and a threaded hole 46 are opened on the inner side of the ball-supporting ring 43. A mounting groove 47 is opened on the inner side of the base 41.

[0031] As a further implementation of this solution, the top of the support column 24 is fixedly connected to the scanning measuring instrument 1, the support column 24 extends to the inner side of the mounting slot 22, and a bearing 25 is fixedly connected to the outer side of the support column 24. The outer side of the bearing 25 is fixedly connected to the inner side of the mounting slot 22. The support column 24 is rotatably connected to the mounting housing 21 through the bearing 25. With the above settings, the scanning measuring instrument 1 can be stably driven to rotate, ensuring the stability of the scanner during horizontal correction and scanning, and improving scanning accuracy and reliability.

[0032] As a further implementation of this solution, the outer side of the ball 26 is fitted with the inner side of the first ball groove 44, the extension rod 27 is embedded in the interior of the mounting groove 47, and the first flange 28 is located at the lower end of the base 41. With the above arrangement, the ball-supporting ring 43 supports the surface scanning measuring instrument 1, the horizontal correction component 2 and the counterweight component 3, and at the same time allows the ball 26 to move at multiple angles inside the first ball groove 44, so that the surface scanning measuring instrument 1 is not limited by angle during horizontal correction. The opening of the mounting groove 47 provides space for the movement of the extension rod 27.

[0033] As a further implementation of this solution, the counterweight assembly 3 includes a second flange 31, a connecting rod 32 fixedly connected to the bottom of the second flange 31, and a counterweight metal block 33 fixedly connected to the bottom of the connecting rod 32. The second flange 31 is fixedly connected to the first flange 28 by bolts. With the above arrangement, under the counterweight action of the counterweight metal block 33, the levelness of the scanning measuring instrument 1 can be automatically corrected. At the same time, the counterweight assembly 3 can be flexibly replaced according to the weight of the scanner to adapt to scanners of different weights, thereby enhancing the versatility and applicability of the device.

[0034] As a further implementation of this solution, the fixing component 5 includes a positioning ring plate 51, a second ball groove 52 is provided on the inner side of the positioning ring plate 51, a guide post 53 is fixedly connected to the bottom end of the positioning ring plate 51, a shaft hole is provided at the front end of the positioning ring plate 51, a screw 54 is rotatably connected to the inner side of the shaft hole of the positioning ring plate 51, the outer side of the screw 54 is spirally connected to the inner side of the threaded hole 46, the outer side of the guide post 53 is slidably connected to the inner side of the guide hole 45, and the inner side of the second ball groove 52 is in close contact with the outer side of the ball 26. Through the above settings, the screw 54 can move up and down by simple rotation, thereby quickly completing the fixing of the scanner and preventing the calibrated scanning measuring instrument 1 from twisting again.

[0035] As a further implementation of this scheme, the bottom end of the base 41 is fixedly connected to the tripod 6, and a gap is provided between the top end of the base 41 and the bottom end of the ball-supporting ring 43. Through the above arrangement, the tripod 6 plays a supporting role for the device, and the gap between the base 41 and the ball-supporting ring 43 provides a gap for the operating screw 54.

[0036] Workflow: When calibrating the level of the surface measuring instrument 1, the tripod 6 is placed on the ground. The weight of the counterweight metal block 33 is three times the combined weight of the upper part of the ball 26. Simultaneously, the counterweight assembly 3 can be replaced entirely based on the weight of the surface measuring instrument 1. Under the influence of the counterweight metal block 33's gravity, it remains vertical. The counterweight metal block 33, through the connecting rod 32, the second flange 31, the first flange 28, and the extension rod 27, causes the ball 26 to rotate. The ball 26 rotates inside the first ball groove 44. The inside of groove 44 is coated with lubricating oil to reduce friction between ball 26 and ball support ring 43. The surface sweeping measuring instrument 1 is rotated via the housing 21, bearing 25, and support column 24. At this time, both the surface sweeping measuring instrument 1 and the counterweight metal block 33 remain vertical, allowing for rapid adjustment of the surface sweeping measuring instrument 1's horizontal position. Rotating the screw 54 through the gap between the base 41 and the ball support ring 43 causes the screw 54 to rotate inside the positioning ring plate 51. Since the screw 54 is helically connected to the inner side of the threaded hole 46, the screw 54 will move downwards. The screw 54 drives the positioning ring plate 51 to move downward. The positioning ring plate 51 slides inside the guide hole 45 through the guide post 53, which limits the movement direction of the positioning ring plate 51. When the positioning ring plate 51 is in close contact with the ball 26 through the second ball groove 52, the ball 26 is fixed under the action of friction, thereby preventing the surface measuring instrument 1 from moving and realizing the horizontal correction of the surface measuring instrument 1. When the surface measuring instrument 1 is scanning, the servo motor 23 is started to drive the support shaft 24 to rotate. The support shaft 24 passes through The bearing 25 rotates inside the mounting groove 22, which can improve the stability of the support column 24 driving the surface scanning measuring instrument 1 to rotate. Through the rotation of the surface scanning measuring instrument 1, the effect of scanning the house 360 ​​degrees can be achieved. Based on the above principles, when scanning multiple points, the device can automatically and quickly correct the level of the surface scanning measuring instrument 1. This correction method can significantly reduce the experience requirements of the staff, improve the applicability, and the convenience of level correction of the surface scanning measuring instrument 1. At the same time, this correction does not affect the surface scanning measuring instrument 1 from performing 360-degree scanning.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
