When testing the core accuracy of a laser level, a precision testing device is required, hence the urgent need for a multi-purpose laser level core precision testing device.
[0003] Currently, testing the core accuracy of laser levels requires taking the laser levels to the construction site for on-site testing, which is time-consuming and labor-intensive.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a multi-purpose laser level core accuracy testing device, including a testing base plate 1, a mounting platform 2 at the top of the testing base plate 1, a fixing seat 3 at the top of the mounting platform 2, a fixing rod 4 at the top of the inner wall of the fixing seat 3, and an instrument base 5 at the top of the fixing rod 4. The instrument base 5 is threadedly connected to the fixing seat 3 via the fixing rod 4, and both the outer wall of the fixing rod 4 and the inner wall of the instrument base 5 are threaded. An instrument body 6 is located at the top of the instrument base 5, and the instrument body 6 is vertically positioned relative to the testing base plate 1. The combination of the testing base plate 1, fixing seat 3, instrument base 5, and instrument body 6 facilitates core accuracy testing of the laser level. The instrument body 6 can be easily fixed by rotating and tightening the fixing rod 4 at the top of the fixing seat 3 via the bottom of the instrument base 5. Then, the laser level is turned on to project a cross laser beam, simulating the levelness of the building's ground through the ground calibration axis 7 on the testing base plate 1, thus testing the balance of the laser level and improving the functionality of the device.
[0019] The surface of the testing base plate 1 is marked with a ground calibration axis 7, and both ends of the outer wall of the testing base plate 1 are provided with a rotating shaft 8. The outer wall of the rotating shaft 8 is connected to a testing panel 9. The testing panel 9 forms a rotating structure with the testing base plate 1 through the rotating shaft 8. The testing panel 9 is symmetrical about the central axis of the testing base plate 1, and the surface of the testing panel 9 is marked with a wall calibration axis 10. Connecting blocks 11 are installed on both sides of the top of the testing base plate 1, and limit rods 12 are installed on the inner wall of the connecting blocks 11. The connecting blocks 11 and the limit rods 12 are connected by threads, and the shape of the connecting blocks 11 is "L". With the rotating shaft 8, testing panel 9 and connecting blocks 11, it is convenient to simulate the wall of a building when performing core accuracy testing on the laser level. The core accuracy of the laser level is calibrated and tested through the wall calibration axis 10 on the testing panel 9. It is convenient and quick. The rotating shaft 8 can be used to fold and store the testing panel 9. At the same time, the connecting blocks 11 can be used to fix the testing panel 9 for easy installation.
[0020] Working Principle: When performing core accuracy testing on a laser level, firstly, the instrument body 6 is fixed by rotating and tightening the bottom plate 5 and the top fixing rod 4 of the fixed base 3. Then, the laser level is turned on to project a cross laser beam. By detecting the ground calibration axis 7 on the detection base plate 1, the levelness of the building ground is simulated, and the balance of the laser level is tested, thereby improving the functionality of the device. Then, the detection panels 9 at both ends are rotated to be perpendicular to the detection base plate 1 via the rotating shaft 8, and the detection base plate 1 and the detection panel 9 are fixed by the connecting block 11 and the limiting rod 12. The cross laser beam projected by the instrument body 6 is used to calibrate and mark the wall calibration axis 10 on one detection panel 9. By rotating the instrument body 6, the cross laser beam projected by the instrument body 6 is driven to project. On the other end of the detection panel 9, calibration marks are made. The cross laser projection marks on both ends of the detection panel 9 are compared, and the error is calculated by using the wall calibration axis 10. If the error is greater than 3mm, the accuracy of the laser level needs to be readjusted and calibrated to test the core accuracy of the laser level. In addition, the setting of the rotating shaft 8, detection panel 9 and connecting block 11 makes it convenient and quick to test the core accuracy of the laser level by simulating the wall of the building through the detection panel 9 and calibrating the core accuracy of the laser level through the wall calibration axis 10 on the detection panel 9. The rotating shaft 8 can be used to fold and store the detection panel 9, and the connecting block 11 can be used to fix the detection panel 9 for easy use.
