Description

Technical Field

[0001] The utility model relates to the technical field of an inertial navigation calibrator installation structure, in particular to an inertial navigation calibrator installation structure. Background Art

[0002] After searching, Chinese Patent No. 202222464184.X discloses an inertial navigation calibrator installation structure and an inertial navigation calibrator. When the inertial navigation calibrator is installed through the inertial navigation calibrator installation structure of the utility model, on the one hand, the inertial navigation calibrator can be quickly installed to the specified position and facilitate subsequent maintenance. On the other hand, the vibration resistance of the inertial navigation calibrator is significantly improved.

[0003] Under the existing technology, inertial navigation calibrators are often used in the field of aerospace, and the staff will install them in the specified position through the installation structure. However, the existing installation structure is basically fixed by multiple groups of screws. When the inertial navigation calibrator is damaged, the staff needs to disassemble it. Because it is fixed with screws, the staff can only screw the screws one by one to complete the disassembly of the inertial navigation calibrator. This process has many operating steps, which is time-consuming and labor-intensive. It is not easy for the staff to quickly install and disassemble it, which prolongs the working time of the staff and indirectly affects the labor intensity of the staff. Utility Model Content

The outer surfaces of the first short rod 6 and the second short rod 7 are sleeved with a return spring 8. The reaction force generated by the extrusion of the return spring 8 can continuously squeeze the moving block 3 inward, so that the moving block 3 can drive the limit block 2 along the inner wall of the mounting seat 1. The mounting seat 1 is moved inwardly until the limit block 2 passes through the inner wall of the mounting seat 1 and is finally firmly inserted into the inner part of the limit hole 15, which effectively improves the fixing effect between the mounting seat 1 and the mounting plate 14, and indirectly ensures the stability of the inertial navigation calibrator body 16. A sliding groove 9 is provided inside the mounting seat 1, and an extrusion spring 10 is fixedly connected to the inner wall at the bottom of the sliding groove 9. The reaction force generated by the extrusion of the extrusion spring 10 can indirectly drive the moving plate 13 to move upward, so that the moving plate 13 can drive the mounting plate 14 and the inertial navigation calibrator body 16 to move upward until the mounting plate 14 is lifted out of the mounting seat 1. The interior of the device saves time and effort, and is convenient for the staff to take the inertial navigation calibrator body 16, which speeds up its disassembly. The extrusion spring 10 is in an extruded state, and the top of the extrusion spring 10 is fixedly connected to the sliding block 11, and the upper surface of the sliding block 11 is fixedly connected to the connecting rod 12. The top of the connecting rod 12 passes through the inner wall of the bottom of the mounting seat 1, and the top of the connecting rod 12 is fixedly connected to the moving plate 13.

[0025] In order to enable the staff to install the mounting base 1 on the specified position, the utility model has a connecting block 17 fixedly connected to the bottom of the outer side of the mounting base 1, and a connecting hole 18 is opened on the outer side of the connecting block 17. The staff controls the electric screwdriver prepared in advance to drive the screw to rotate downward along the inside of the connecting hole 18 until part of the screw passes through the inside of the connecting hole 18 and finally rotates firmly into the inside of the specified position, thereby enabling the staff to install the mounting base 1 on the specified position.

[0027] In order to extend the service life of the return spring 8 and the extrusion spring 10, the utility model sets the number of the return spring 8 and the extrusion spring 10 to four groups, and the manufacturing materials of the return spring 8 and the extrusion spring 10 are both set to silicon-manganese spring steel. The springs made of silicon-manganese spring steel have good return effect and are not easy to deform, thereby extending the service life of the return spring 8 and the extrusion spring 10.

[0028] In order to facilitate the movement of the moving block 3 along the inside of the mounting seat 1, the utility model provides a moving groove inside the mounting seat 1, and the inner diameter of the moving groove is matched with the outer diameter of the moving block 3, so as to facilitate the movement of the moving block 3 along the inside of the mounting seat 1.

[0029] In order to ensure that the limit block 2, the moving block 3, the transmission plate 4, the hand-held rod 5, the first short rod 6 and the second short rod 7 are not easily damaged when being used, the utility model sets the limit block 2, the moving block 3, the transmission plate 4, the hand-held rod 5, the first short rod 6 and the second short rod 7 as the manufacturing materials. The stainless steel has a high hardness and is not easy to deform, thereby ensuring that the limit block 2, the moving block 3, the transmission plate 4, the hand-held rod 5, the first short rod 6 and the second short rod 7 are not easily damaged when being used.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0031] When in use, the staff places the mounting base 1 on the designated position in advance, and then controls the electric screwdriver prepared in advance to drive the screw to rotate downward along the inside of the connecting hole 18 until part of the screw passes through the inside of the connecting hole 18, and finally firmly rotates it into the inside of the designated position, thereby completing the installation of the mounting base 1. When the staff needs to disassemble the inertial navigation calibrator body 16, the staff controls the hand-held rod 5 to drive the transmission plate 4 and the moving block 3 to move outward along the inside of the mounting base 1, and at the same time, the moving block 3 drives the limit block 2 to move outward, and at the same time, the moving block 3 drives the first short rod 6 to squeeze the reset spring 8 outward until the limit block 2 is moved out of the limit hole 15, thereby releasing the fixation of the mounting plate 14.
