Description

Technical Field

[0001] The utility model relates to the technical field of laser levels, in particular to a core structure of a laser level. Background Art

[0002] The electronic laser level is a full-space three-dimensional laser line device that can provide automatic leveling. Its working principle is that when the instrument is tilted at an angle within the working range of the level (high-precision long level or circular level), the mutually perpendicular laser lines on the compensator pendulum inside the instrument always remain perpendicular to each other under the action of gravity.

[0003] Existing level adjustment methods for spirit levels are generally divided into active and passive types. The passive type mainly uses gravity suspension or liquid buoyancy to adjust the movement state, while the active type uses mechanical drive to adjust the movement's horizontal state. Therefore, the movement assembly determines the performance and accuracy of the entire mechanical level. However, existing movement assemblies not only expose wiring, but are also too large and have low assembly efficiency. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a core structure of a laser level, which solves the problems raised in the background art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a movement structure of a laser level, including a pendulum and a horizontal and vertical dual-beam module, the pendulum and the module are detachably connected, the center line of the module is perpendicular to the center line of the pendulum, and a PCB board is installed on the upper part of the pendulum.

[0006] A cross-center coaxial shaft is installed at one end of the top of the above-mentioned pendulum body. The cross-center coaxial shaft is provided with an assembly hole for the cross-center outer ring shaft to pass through in its horizontal direction. The cross-center outer ring shaft also passes through the through hole in the horizontal direction of the cross-axis center outer ring. Horizontal protrusions are left on both sides of the top of the cross-axis center outer ring for installing the cross-axis center outer ring rubber pad.

[0007] A threaded column for installing a heavy hammer is provided in the vertical direction of the lower part of the pendulum body, and a conductive rubber ring is sleeved on the lower part of the heavy hammer.

[0008] A threaded hole for installing a counterweight is provided in the horizontal direction of the lower side of the pendulum body.

[0009] The cross center outer ring shaft and the cross shaft center outer ring are rotationally matched through a fixed bearing, a handle ring and a bushing, and the bushing is tightly attached to the cross center and coaxial in the horizontal direction.

[0010] The utility model provides a movement structure of a laser level. It has the following beneficial effects: the movement structure of the laser level is assembled in a modular manner, is compact and lightweight, and is easy to install. The module integrates both horizontal and vertical light beams, which greatly saves space and improves assembly efficiency. At the same time, since the center line of the laser module and the center line of the pendulum body are on the same plane, the overall accuracy of the instrument will be further improved. The pendulum body and the module are detachably connected, using parts with simpler size and structure and a more detailed assembly method, solving the problems of the traditional movement pendulum shaft mechanism having a complex design structure, being difficult to process and shape, increasing material costs, and being difficult to disassemble and assemble parts. The structure is simple and easy to process, thereby achieving the effect of saving manufacturing costs and facilitating disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: In conjunction with the specification Figure 1-8 It can be seen that in order to solve the problems in the prior art that the traditional laser level movement pendulum shaft mechanism has a complex design structure, is not easy to process and form, has high material cost and is not easy to disassemble and assemble parts, the present application specifically designs a movement structure of a laser level, including a pendulum body 8 and a horizontal and vertical dual-beam module 12, the pendulum body 8 and the module 12 are detachably connected, the center line of the module 12 is perpendicular to the center line of the pendulum body 8, a PCB board is installed on the upper part of the pendulum body 8, and is assembled in a modular manner. The overall size is small and light, and the installation is simple. Moreover, the module 12 integrates horizontal and vertical light beams, which greatly saves space and improves assembly efficiency. At the same time, since the center line of the laser module 12 and the center line of the pendulum body 8 are on the same plane, the overall accuracy of the instrument will be further improved; the pendulum body 8 and the module 12 are detachably connected, using parts with simpler size and structure and a more detailed assembly method, with a simple structure, easy processing, saving manufacturing costs and easy disassembly and assembly.

[0022] During the specific implementation process, a cross-center coaxial shaft 3 is installed at one end of the top of the above-mentioned pendulum body 8. The cross-center coaxial shaft 3 is provided with an assembly hole along its horizontal direction for the cross-center outer ring shaft 4 to pass through. The cross-center outer ring shaft 4 also passes through the horizontal through-hole of the cross-axis center outer ring 2, so as to achieve the effect that the movement and the pendulum body 8 can swing arbitrarily within a certain range. Horizontal protrusions are left on both sides of the top of the cross-axis center outer ring 2 for installing the cross-axis center outer ring rubber pad 1. The setting of the cross-axis center outer ring rubber pad 1 reduces the influence of factors such as vibration on the movement structure.

[0023] It should be noted that the horizontal and vertical dual beam module 12 is preferably a HOLASER-H0-S635P10-1634 level laser module;

[0024] The above-mentioned cross center outer ring shaft 4 and the cross shaft center outer ring 2 are rotatably matched through fixed bearings 7, handle rings 6 and bushings 5. In order to fix the relative position of the bearing 7, the bearing 7 is fixed with handle rings 6 and bushings 5 ​​in front and behind. The bushing 5 is horizontally close to the cross center coaxial 3 to achieve overall fixation.

[0025] A threaded column for mounting a weight 10 is vertically provided at the lower portion of the pendulum body 8 , and a conductive rubber ring 11 is sleeved at the lower portion of the weight 10 .

[0026] A threaded hole for mounting the counterweight 9 is provided horizontally on the lower side of the pendulum body 8. The center of gravity of the module 12 and the counterweight 9 are located on both sides of the center of gravity of the pendulum body 8. By adjusting the center of gravity of the module 12 and the counterweight 9, the center line position of the pendulum body 8 can be adjusted together so that the center line of the pendulum body 8 is perpendicular to the horizontal plane.

[0027] The implementation principle of the above embodiment is as follows: the cross-axis center outer ring 2 is fixed by the cross-axis center outer ring rubber pad 1, and the swing of the pendulum 8 in one horizontal direction is achieved based on the fixation of the handle ring 6, the bushing 5, and the bearing 7. The swing of the pendulum 8 in another horizontal direction is achieved based on the limit bearing and the cross center coaxial 3, thereby achieving arbitrary swing of the movement and the pendulum 8 within a certain range, facilitating cost control and the convenience of disassembly and assembly, and at the same time improving the convenience of interchangeability of the multi-line horizontal modules 12.
