[0018] An embodiment of the present utility model provides an installation and protection structure for an inertial navigation device. As Figure 1-2 shown, it includes an equipment base 11, an extension base 12, an installation push plate 15, and an auxiliary installation structure. The extension base 12 is arranged on the four sides of the equipment base 11. An installation slot 13 is opened on the lower inner side of the extension base 12. The equipment base 11 abuts against the inner wall of the installation slot 13. A hinge joint 14 is fixedly arranged on the extension base 12. The installation push plate 15 is hinged between the hinge joints 14. The installation push plate 15 is used to abut against the outer surface of the inertial navigation device. The auxiliary installation structure is arranged between the installation push plate 15 and the vertical part of the extension base 12.

[0019] A groove is formed in the vertical portion of the extension base 12, and the auxiliary installation structure is arranged between the groove of the extension base 12 and the installation push plate 15.

[0020] As Figure 2 shown, the auxiliary installation structure includes a connection head 16, a connection swing arm 20 and a connecting rod 22. The connection head 16 is fixedly arranged on one side of the installation push plate 15 close to the vertical portion of the extension base 12. The connection swing arm 20 is hinged between the inner walls of the groove of the extension base 12. The tail of the connection swing arm 20 extends to the outside of the extension base 12. The connecting rod 22 is hinged between the connection head 16 and the connection swing arm 20.

[0021] When the connection swing arm 20 and the connecting rod 22 maintain an axis - coincident state, the installation push plate 15 maintains a vertical state.

[0022] An electro - hydraulic push rod 21 is arranged between one end of the connection swing arm 20 far from the installation push plate 15 and the extension base 12. The electro - hydraulic push rod 21 is electrically connected to the vehicle body.

[0023] When the inertial navigation device needs to be installed, the installation slot 13 in the extension base 12 and the device base 11 are installed with bolts. The electro - hydraulic push rod 21 is started. The power output end of the electro - hydraulic push rod 21 abuts against the tail of the connection swing arm 20 and jacks it up to a horizontal state. The connection swing arm 20 drives the connecting rod 22 to rotate to a horizontal state through the hinge point, and further makes the installation push plate 15 swing to a vertical state. The surrounding installation push plates 15 push the housing of the inertial navigation device located on the base of the inertial navigation device and limit it, thereby assisting in the installation and protecting the housing of the inertial navigation device after the installation is completed.
