In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The utility model is further described below in conjunction with embodiments.

[0039] Example:

[0040] This solution provides a horizontal light leveling structure and a measuring instrument having the same, refer to the attached Figure 1-7 The present solution mainly includes three parts: a fixed panel 1, a laser instrument 2 and a horizontal lamp 3. The fixed panel 1 is cylindrical as a whole, and the laser instrument 2 is movably installed on the fixed panel 1, and a lamp hole for emitting laser is set on the side of the laser instrument 2.

[0041] Specifically, the lamp hole on the laser instrument 2 for emitting laser is arranged at one end of the laser instrument 2 away from the axial direction of the fixed panel 1, the distance between the lamp hole and the outer circumferential side surface of the fixed panel 1 is smaller than the distance between the lamp control and the center of the fixed panel 1, and the angle between the direction of the lamp hole of the laser instrument 2 and the upper end surface of the fixed panel 1 is adjustable.

[0042] In the present case, a fixed seat 11 is provided at the upper end of the fixed panel 1, and the side of the laser instrument 2 away from the axial direction of the fixed panel 1 is hinged on the fixed seat 11, and the other side of the laser instrument 2 is movably connected to the fixed panel 1 through an adjusting member 21. The fixed seat 11 includes a horizontal part fixed on the fixed panel 1 and vertical parts vertically arranged on both sides of the horizontal part, and the laser instrument 2 is rotatably installed between the two vertical parts.

[0043] The adjusting member 21 can adjust the angle between the laser device 2 and the fixed panel 1 .

[0044] Specifically, the adjusting member 21 includes a fixed shaft column 211 and a cross piece 212. The fixed shaft column 211 is vertically fixed to the upper end of the fixed panel 1, and the cross piece 212 is vertically fixed to the upper end of the fixed shaft column 211. Specifically, the cross piece 212 is provided with a first opening and a second opening whose axes are parallel to each other, and the first opening is fixed above the fixed shaft column 211 by a connecting screw, and the second opening is directly opposite to the upper end of the laser instrument 2.

[0045] A screw hole 213 is provided on one side of the upper end of the laser instrument 2 corresponding to the second opening, and an adjusting screw 214 is fitted in the screw hole 213. The adjusting screw 214 passes through the second opening and fits with the screw hole 213, and a return spring 215 is also sleeved on the outside of the adjusting screw 214. The return spring 215 is arranged between the cross piece 212 and the upper end surface of the laser instrument 2.

[0046] Therefore, when the emission angle of the laser device 2 needs to be adjusted, the adjusting screw 214 is turned to drive the laser device 2 to swing around its hinge point.

[0047] Optionally, in order to facilitate maintenance and disassembly, the laser instrument 2 and the fixing base 11 in this case can be quickly disassembled.

[0048] Specifically, two U-shaped grooves 111 with openings upward are provided on the fixing seat 11, and the two U-shaped grooves 111 are respectively arranged on the two vertical parts. An axle pin 22 is vertically provided on both sides of the laser instrument 2, and each axle pin 22 protrudes from the U-shaped groove 111. The axle pins 22 are respectively inserted into the two U-shaped grooves 111. Therefore, during installation, the two axle pins 22 can be aligned with the upper part of the two U-shaped grooves 111 and pressed downward. In order to ensure the smooth rotation of the laser instrument 2, a small gap is provided between the axle pin 22 and the U-shaped groove 111 in this case, and a certain amount of lubricating oil can be applied if necessary.

[0049] In order to prevent the laser instrument 2 from being displaced due to excessive rotation speed, an elastic band 112 is provided on the fixing seat 11 . The elastic band 112 is attached to the upper end of the laser instrument 2 , and both sides thereof are detachably connected to the fixing seat 11 .

[0050] In this case, holes are provided on both sides of the elastic band 112, and a hook is vertically provided on the end faces of the two vertical parts. During assembly, the two sides of the elastic band 112 are put on the hook through the holes to achieve elastic binding of the laser instrument 2.

[0051] However, most similar products on the market do not have a leveling structure for the horizontal light 3. Most of them are based on manual or artificial judgment of whether the annular rays formed by the horizontal light 3 are in the same plane as the laser instrument 2. Such a setting is not only of low precision but also quite inconvenient. Therefore, when the instrument rotates, the annular rays of the horizontal light 3 will fluctuate and will not be in the same plane as the scanning of the laser instrument 2, which will result in the horizontal light 3 having little actual effect and can only be used as a reference. The leveling of the whole machine still has to be based on the laser instrument 2, which will inevitably produce certain errors.

[0052] In the present solution, a leveling structure related to the horizontal lamp 3 is specially added to keep the annular ray plane of the horizontal lamp 3 parallel to the scanning plane of the laser instrument 2, so that the instrument will not fluctuate when rotating.

[0053] Specifically, in this case, the horizontal lamp 3 is vertically arranged above the fixed panel 1 through a leveling bracket 31, and the end faces of the leveling bracket 31 and the fixed panel 1 on the opposite side are always kept parallel. Three support modules 32 are arranged between the leveling bracket 31 and the fixed panel 1, and the three support modules 32 are arranged in a circle in the axial direction of the fixed panel 1. In this case, the distance between the leveling bracket 31 and the fixed panel 1 is also adjustable.

[0054] Each supporting module 32 includes a stud 321, which is vertically installed on the upper end of the fixed panel 1. The leveling bracket 31 is fixed on the stud 321 and is parallel to the end face of the fixed panel 1, and a spring 322 is sleeved on the outer side of each stud 321. The leveling bracket 31 is sleeved on the stud 321 and abuts against the top of the spring 322. Under the action of the three springs 322, the same thrust will always be applied to the bottom end of the leveling bracket 31, so that the horizontal light 3 always remains on the same plane.

[0055] Moreover, in the present case, a nut matching with the stud 321 is arranged above the leveling bracket 31. In practice, the distance between the leveling bracket 31 and the fixed panel 1 can be adjusted by screwing the nut. This limiting method not only facilitates the adjustment of the horizontal light, but also the connection method which is not a fixed connection also provides convenience for assembly.

[0056] In combination with actual needs, a driving structure for driving the fixed panel 1 to rotate along its axial direction is provided at the bottom end of the fixed panel 1 .

[0057] It is worth mentioning that the fixing structures such as the leveling bracket 31 and the fixing seat 11 in the leveling structure of this case are all made of full metal structure, which greatly reduces the misalignment problem caused by the deformation of the plastic material (extrusion deformation and thermal expansion and contraction).

[0058] The utility model also provides a measuring instrument, including a main body 4 and the above-mentioned horizontal light leveling structure, the horizontal light leveling structure is rotatably mounted on the main body 4, a motor 41 is provided inside the main body 4, and the output shaft of the motor 41 passes through an encoder 42 located above it and is connected to the bottom end of the fixed panel 1.

[0059] The motor 41 in this case is a servo motor, which avoids the stepper motor commonly used on the market. As we all know, the stepper motor vibrates once every few dozen degrees of rotation, and each vibration produces a large number of abnormal points. The servo motor can not only adjust the speed in real time to adapt to different measurement needs during use, but also generate more measurement points at a slow speed, making the results more accurate and greatly reducing manual corrections after measurement.

[0060] The encoder 42 in this case uses a high-precision encoder to replace the low-precision encoder integrated in the traditional motor, which not only makes the measurement result more accurate, but also does not impose too many restrictions on the placement of the instrument.

[0061] For example, taking the cabinet countertop measured indoors as an example, in order to meet the precision requirement, the error within a radius of 3 meters must reach plus or minus 2mm, and when the laser distance accuracy is plus or minus 1mm, the angle accuracy must be within plus or minus 0.1. However, most of the encoders integrated in the motors that directly drive the measuring instrument 2 to rotate are unevenly calibrated, and the angle error can be as high as plus or minus 0.5 or more, resulting in a final result error of more than 20 times, affecting the measurement accuracy. The additional high-precision encoder 42 can meet the angle accuracy requirement of plus or minus 0.1.

[0062] In addition, according to geometric principles, when the angle error is large, if the angle between two points is close to 180 degrees, the error of the calculated distance result is not large. Similar products on the market that use motor integrated encoders require that the instrument must be placed at a specified position during measurement (such as the first corner where the scan starts) so that the important turning points of the measured space are close to 180 degrees, thereby reducing the distance error between the two points. However, the errors at other positions cannot meet the precision requirements, and the errors are more obvious for special-shaped spaces.

[0063] If a professional high-precision encoder is added, there is no requirement for the placement position. If there is an obstacle in the corner, the instrument can be placed in the center of the room. If there is an obstacle in the center of the room, it can be placed in the corner or against the wall. It is very flexible and can produce very accurate measurement results at each position. If the measured space is not blocked, the measuring instrument 2 can be rotated once to complete the measurement operation at one time.

[0064] Specifically, the measuring instrument in this case consists of two parts, namely a main body 4 and the above-mentioned horizontal light leveling structure. The inside of the main body 4 is arranged from bottom to top with a battery 43, a motor 41, an encoder 42 and a fixed panel 1. Two circuit boards 411 are also arranged in the main body 4. The fixed panel 1 is driven to rotate periodically by the output shaft on the motor 41. A charging hole and a switch are also arranged at the outer end of the main body 4. A bearing is arranged between the fixed panel 1 and the main body 4. The main body 4 is also detachable and has a main unit cover, which is mounted on the outside of the fixed panel 1, and a glass cover is fixed on the main unit cover, which is mounted on the outside of the horizontal light to prevent moisture and dust.

[0065] It should be noted that before use, the angle of the laser instrument 2 and the level 3 need to be adjusted, and the host cover needs to be removed for adjustment, or a through hole needs to be directly opened on the host cover (not shown in the figure), which is a well-known technology and will not be elaborated here.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
