The adjusting rod is a manually adjustable telescopic rod, one end of which is hinged to the middle of the first mounting plate, and the other end of which is hinged to the middle of the second mounting plate.

[0006] Furthermore, the base plate includes an outer plate and an inner plate.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] This utility model embodiment provides an electronic compass angle information calibration frame, such as Figure 1-2As shown, the system includes a base plate 1, a first mounting plate 2, a second mounting plate 3, and an adjusting rod 4. The base plate 1 is an automatically retractable plate. One end of the base plate 1 is hinged to the lower end of the first mounting plate 2, and the other end of the base plate 1 is hinged to the lower end of the second mounting plate 3. The second mounting plate 3 or the first mounting plate 2 can be used to mount an electronic compass. The upper end of the second mounting plate 3 is hinged to the upper end of the first mounting plate 2. The adjusting rod 4 is a manually adjustable telescopic rod. One end of the adjusting rod 4 is hinged to the middle of the first mounting plate 2, and the other end of the adjusting rod 4 is hinged to the middle of the second mounting plate 3. The length of the adjusting rod 4 can be adjusted manually. At the same time, the base plate 1 automatically retracts and extends, which can adjust the tilt angle of the first mounting plate 2 and the second mounting plate 3. This allows for adjustment of the tilt angle of the electronic compass mounted on the first mounting plate 2 or the second mounting plate 3, testing the output error of the electronic compass at different tilt angles, and calibrating the electronic compass through the output error. There is no need to change the test angle by replacing the inclined blocks of different angles, making the operation convenient.

[0017] In this embodiment, the base plate 1 includes an outer plate 11 and an inner plate 12. The outer plate 1 is hinged to the lower end of the first mounting plate 2. The outer plate 11 has a telescopic cavity inside. One end of the inner plate 12 is slidably disposed inside the telescopic cavity, and the other end is hinged to the lower end of the second mounting plate 3. For the base plate 1, it only needs to meet the requirement of being able to automatically extend and retract. Therefore, it is not limited to a specific structure. For example, in some embodiments, the base plate 1 includes at least three plates that are nested together in sequence. One plate is fitted inside the telescopic cavity of the adjacent plate. The first plate is hinged to the lower end of the first mounting plate 2, and the last plate is hinged to the lower end of the second mounting plate 2. In other embodiments, the base plate is other automatically extendable structures. All automatically extendable base plates 1 are within the protection scope of this utility model.

[0018] In this embodiment, the adjusting rod 4 includes an outer rod 41 and an inner rod 42. The outer rod 41 has threaded holes with opposite helical directions at both ends. The inner rod 42 includes two threaded rods, one end of which is threaded into the interior of both ends of the outer rod 41, and the other end of which is hinged to the middle of the first mounting plate 2 and the second mounting plate 3. The length of the adjusting rod 4 can be adjusted by rotating the outer rod 41. The adjusting rod 4 only needs to be able to be manually adjusted for extension and retraction; therefore, it is not limited to a specific structure. For example, in some embodiments, the adjusting rod 4 includes an outer rod 41. The outer rod 41 has a threaded hole inside and an inner rod 42. The inner rod 42 includes two rods, one of which is a threaded rod with one end threadedly connected to the inside of one end of the outer rod 41 and the other end hinged to the middle of the first mounting plate 2. The other rod is an unthreaded rod with one end rotatably connected to the inside of the other end of the outer rod 41 and the other end hinged to the middle of the second mounting plate 3. The length of the adjusting rod 4 can also be adjusted by rotating the outer rod 41. In some other embodiments, the adjusting rod 4 is a manually adjustable telescopic structure. All manually adjustable telescopic adjusting rods 4 are within the protection scope of this utility model.

[0019] In this embodiment, a locking nut 43 is threaded onto the threaded rod. After the length of the adjusting rod 4 is adjusted, the locking nut 43 can lock the threaded rod and the outer rod 41 together, preventing the threaded rod and the outer rod 41 from loosening during use and affecting the use of the calibration frame.

[0020] To make the operator feel more comfortable when rotating the outer rod 41, in this embodiment, a rubber sleeve 44 is installed on the outside of the outer rod 41, and the rubber sleeve 44 is provided with anti-slip protrusions to prevent the operator's hand from slipping when rotating the outer rod 41.

[0021] Specific principle: When calibrating the electronic compass, the electronic compass is installed on the first mounting plate 2 or the second mounting plate 3. The length of the adjusting rod 4 can be adjusted by rotating the outer rod 41. At the same time, the base plate 1 automatically extends and retracts, so that the tilt angle of the first mounting plate 2 and the second mounting plate 3 can be adjusted. After adjustment, the threaded rod and the outer rod 41 can be locked by the locking nut 43 to fix the tilt angle of the first mounting plate 2 and the second mounting plate 3. The output error of the electronic compass at different tilt angles is tested, and the calibration of the electronic compass is completed by the output error.
