[0002] Electronic level is a modern measuring tool used to accurately measure the elevation difference between ground points. Compared with traditional optical levels, electronic levels have higher accuracy, efficiency and automation. The main components of electronic level: Electronic level host: contains digital sensor, processor and display. Barcode ruler: a specially designed ruler with barcodes that can be recognized by the instrument. Tripod: used to stably support the instrument. Data storage and transmission device: such as built-in memory, SD card or interface for connecting to a computer. Its working principle: The instrument reads the information on the barcode ruler through the built-in CCD or CMOS sensor, and the processor analyzes the image data and calculates the distance and height difference between the instrument and the ruler.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0018] See also Figure 1-Figure 2, an electronic leveling device with precise measurement function, comprising an electronic leveling instrument 10, a bracket 11, and a protective shell 12; the electronic leveling instrument 10 is fixedly installed inside a measuring instrument installation box 13 with an opening on one side, the measuring instrument installation box 13 is placed in the protective shell 12 and flipped inside and outside to move, one side of the protective shell 12 is set to an opening shape, and two groups of flipping components are symmetrically arranged between the upper and lower sides of the measuring instrument installation box 13 and the upper and lower inner walls of the protective shell 12, and the flipping components are used to control the measuring instrument installation box 13 to swing inside and outside along the opening of the protective shell 12 to adjust the placement angle, and the measuring end of the electronic leveling instrument 10 faces the opening side of the measuring instrument installation box 13. When measuring, the measuring instrument installation box 13 is rotated with the cooperation of the flipping component. The opening end of the measuring instrument 10 is directed toward the outside of the protective shell 12 to perform level measurement within a certain angle range. When it is necessary to store it, the measuring instrument installation box 13 is rotated to rotate the measuring end of the electronic level measuring instrument 10 toward the inside of the protective shell 12. At the same time, a circle of elastic sealing ring 21 is arranged on the outer wall of the opening end of the measuring instrument installation box 13. The elastic sealing ring 21 rotated to the inner wall of the protective shell 12 is forced to contact the inner wall of the protective shell 12. At this time, the opening side of the measuring instrument installation box 13 is fully sealed, thereby the electronic level measuring instrument 10 is sealed and stored in the measuring instrument installation box 13, that is, the electronic level measuring instrument 10 in the unused state is effectively protected, thereby realizing the adjustable level measurement and safe storage function of the electronic level measuring instrument 10.
[0019] In the embodiment of the present invention, a mounting base 14 is fixedly mounted at the bottom of the protective housing 12, and a bracket 11 is connected to the middle of the bottom of the mounting base 14. The mounting base 14 is supported by the bracket 11 to control the measuring instrument installation box 13, the electronic level measuring instrument 10 and other structures inside the protective housing 12 to be stably placed and operated;
[0020] The structure and operation of the electronic level measuring instrument 10 have been described in the background technology and will not be described in detail here.
[0021] In one embodiment of the present invention, see Figure 1-Figure 4The flip assembly includes a slide rail 15 arranged on the upper and lower walls inside the protective shell 12, and a slider 16 is installed at the ends of the upper and lower walls of the measuring instrument installation box 13, which is slidably connected along the inside of the slide rail 15. At the same time, a rotating shaft 17 is rotatably connected at the middle position of the upper and lower sides of the measuring instrument installation box 13, and a swing rod 18 is connected to one end of the rotating shaft 17 facing the slide rail 15. The end of the swing rod 18 is connected to a swing shaft 20 rotatably connected to the end of the slide rail 15. The slider 16 slides horizontally along the inside of the slide rail 15, and the two ends of the swing rod 18 are connected with the rotating shaft 17 on the measuring instrument installation box 13 and the swing shaft 20 at the end of the slide rail 15, so as to stably control the measuring instrument installation box 13 to flip and swing inside and outside along the opening of the protective shell 12, so as to achieve the angle adjustment and flip storage of the measuring instrument installation box 13;
[0022] Specifically, when the measuring instrument mounting box 13 swings to an angle parallel to the inner wall of the protective shell 12, the swing rod 18 will contact the slider 16. At this time, the slider 16 will partially hinder the horizontal swing of the swing rod 18, causing it to be unable to fully swing to a horizontal angle. Therefore, an axis groove 19 is opened on the inner wall of the swing rod 18 near the swing axis 20. The setting of the axis groove 19 ensures that a moving space is provided for the slider 16, thereby maintaining the horizontal swing of the swing rod 18.
[0023] As a preferred embodiment of the present invention, in order to facilitate the user to smoothly pull the measuring instrument installation box 13 to flip and swing it, a plurality of pull ring grooves 22 are opened on the front and rear side walls of the measuring instrument installation box 13, and a pull ring 23 is installed inside the pull ring groove 22. The pull ring 23 is used to provide a pulling point for the operator. At the same time, it is arranged inside the measuring instrument installation box 13 and will not affect the contact between the measuring instrument installation box 13 and the inner wall of the protective shell 12.
[0024] As a preferred embodiment of the present invention, refer to Figure 5 The elastic sealing ring 21 includes a circle of mounting ring 27 installed on the outer wall of the open end of the measuring instrument installation box 13. A circle of telescopic ring groove 25 is opened in the inner wall of the mounting ring 27. The inside of the telescopic ring groove 25 is connected to a sealing ring 24 through multiple evenly distributed springs 26. When the open end of the measuring instrument installation box 13 is transferred to the inner wall relative to the open end of the protective shell 12, the spring 26 is compressed by force, and the sealing ring 24 is fully in contact with the inner wall of the protective shell 12, thereby sealing the electronic level measuring instrument 10 in the measuring instrument installation box 13.
[0025] The working principle of the utility model is: in the idle position of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical components are electrically connected in a sequential working order. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, the pull ring 23 is manually controlled to slide in the slider 16 and the slide rail 15, and the swing of the swing rod 18, so that the open end of the measuring instrument installation box 13 is flipped outward. At this time, the electronic level measuring instrument 10 is started to perform leveling measurement of the corresponding angle. When not in use, the above operation is repeated again to transfer the open end of the measuring instrument installation box 13 to the inner wall of the protective shell 12, so that it is horizontal with the inner side relative to the open end of the protective shell 12, and then the open end of the measuring instrument installation box 13 is sealed under the contact of the elastic sealing ring 21, thereby sealing the electronic level measuring instrument 10 in the measuring instrument installation box 13.
[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
