[0002] An inertial navigation device is an autonomous navigation device that does not rely on external information and does not radiate energy to the outside. Its basic working principle is based on Newton's laws of mechanics. By measuring the acceleration of the carrier in the inertial reference system, integrating it over time, and transforming it into the navigation coordinate system, it is possible to obtain information such as speed, yaw angle, and position in the navigation coordinate system. At present, inertial navigation devices have been widely used in transportation tools such as airplanes, submarines, and space shuttles, as well as missiles. Among them, fiber optic navigation, as a common inertial navigation device, is often used in precision navigation equipment such as ships and aviation due to its small size, light weight, and high reliability. Since fiber optic navigation has high requirements for the relative stability of the installation platform, it is necessary to monitor it regularly for looseness.

The bottom end of the navigation module body is fixed to the inner side of the four lower fixing mechanisms, and the tops of the four lower fixing mechanisms are embedded with upper fixing mechanisms. The tops of the four upper fixing mechanisms are fixed with top covers. The utility model prevents the navigation module body from being damaged by a large impact force by means of a shock absorbing assembly.

[0029] Optionally, in the above technical solution, the fixed box body 2 includes a main box body 21 and a burr 22 , the main box body 21 and the burr 22 are integrally formed, and the laser emitter 33 and the laser receiver 34 are both fixedly connected to the burr 22 .

[0030] Optionally, in the above technical solution, a heat dissipation hole 211 is provided on the side wall of the main box body 21 .

[0031] Optionally, in the above technical solution, the laser emitter 33 and the laser receiver 34 are on the same straight line, the laser emitter 33 and the laser receiver 34 are arranged on both sides of the locking bolt 31, and the number of the laser emitter 33 and the number of the laser receiver 34 are both 4.
