Description

Technical Field

[0001] The utility model relates to the technical field of inertial navigation devices, in particular to a novel inertial navigation device structure. Background Art

[0002] After searching, Chinese Patent No. 202223442531.5 discloses a new inertial navigation device structure. The utility model is provided with a shell in which the inertial navigation can be installed, so that the inertial navigation can be used for protection. At the same time, the rotation of the rotating motor can drive the fan blades to rotate, and through the rotation of the fan blades, the heat generated by the inertial navigation in the shell can be discharged through the connecting pipe, thereby ensuring that the inertial navigation can work normally in the shell. Then, the temperature sensor can be used to detect the working temperature of the inertial navigation. When the temperature of the inertial navigation is too high, the temperature information can be detected and transmitted to the controller. The controller can turn on the electric cooling plate for cooling, thereby reducing the temperature of the inertial navigation, further protecting the inertial navigation, and using the work of the monitor, the staff can observe the working status of the inertial navigation in real time, thereby achieving the effect of protection and monitoring.

[0003] Under the existing technology, in the field of aerospace, workers often use inertial navigation devices, but the shells of some existing inertial navigation devices are flat and smooth. Therefore, when workers need to carry them, they can only pick them up with both hands to carry them, which always occupies the workers' hands, is time-consuming and laborious, and it is not easy for workers to change hands and rest, which makes it inconvenient for workers to carry the inertial navigation devices.

[0022] See also Figure 1-3The utility model provides a technical solution: a novel inertial navigation device structure, including an inertial navigation device body 1 and a fixing plate 2, the upper surface of the inertial navigation device body 1 is fixedly connected with the fixing plate 2, the rear side of the outer side of the fixing plate 2 is provided with a first limiting hole 3, the top of the outer side of the fixing plate 2 is provided with a second limiting hole 4, the bottom of the outer side of the fixing plate 2 is fixedly plugged with a fixing shaft 5, the outer surface of the fixing shaft 5 is movably sleeved with a connecting plate 6, the rear side of the outer side of the connecting plate 6 is fixedly plugged with a connecting rod 7, and the connecting rod 7 is fixedly plugged with a connecting rod 7. The inner side of the plate 6 is fixedly connected with a fixing rod 8, and the top of the outer surface of the fixing rod 8 is provided with a through groove 9. The outer side of the fixing rod 8 is movably connected with a limiting rod 10, which passes through the outer side of the connecting plate 6 and then is movably connected with the first limiting hole 3. The inner end of the limiting rod 10 is fixedly connected with a moving block 11, and the top of the outer surface of the moving block 11 is fixedly connected with a hand-held block 12. The hand-held block 12 is controlled to drive the limiting rod 10 to move out of the first limiting hole 3, and then the connecting plate 6 is controlled to rotate ninety degrees to the front side. The limiting rod 10 is then controlled to be inserted into the interior of the second limiting hole 4 to fix it. Then, the staff uses one hand to hold the connecting rod 7 and the sponge layer 18 to apply an upward pulling force to the device, and the device can be lifted and carried, which saves time and effort, realizes the function that the staff can change hands and rest, and is convenient for the staff to carry the inertial navigation device body 1. The hand-held block 12 is slidably connected to the through groove 9, and the inner side of the moving block 11 is fixedly connected with a short rod 13, and the outer surface of the short rod 13 is sleeved with a return spring 14. The reaction force generated by the extrusion of the return spring 14 can continuously squeeze the moving block 11 outward, so that the moving block 11 can drive the limiting rod 10 to move outward along the inside of the fixed rod 8 until the limiting rod 10 passes through the outer side of the fixed rod 8 and the connecting plate 6, and finally is firmly inserted into the first limiting hole 3 or the second limiting hole 4, effectively improving the fixing effect between the connecting plate 6 and the fixing plate 2, and indirectly ensuring the stability of the connecting rod 7 when it is in use.

[0023] In order to facilitate the staff to fix the device on the designated position, the utility model has connection holes 15 on the outer side of the inertial navigation device body 1, and the number of the connection holes 15 is set to four groups. The staff can control the electric screwdriver prepared in advance to drive the screw to rotate downward along the inside of the connection hole 15 until part of the screw passes through the inside of the connection hole 15, and finally firmly rotate it into the inside of the designated position, so that the installation of the device can be completed. This process has fewer operating steps, saves time and effort, and is convenient for the staff to install the device on the designated position.

[0024] In order to realize the heat dissipation function of the device, the utility model provides heat dissipation holes 16 at the tops of the left and right sides of the inertial navigation device body 1, thereby realizing the heat dissipation function of the device.

[0025] In order to improve the stability of the connection between the fixing plate 2 and the inertial navigation device body 1, the utility model has a triangular plate 17 fixedly connected to the bottom of the front side of the fixing plate 2, the lower surface of the triangular plate 17 is fixedly connected to the upper surface of the inertial navigation device body 1, the triangular plate 17 increases the connection area between the fixing plate 2 and the inertial navigation device body 1, and improves the stability of the connection between the fixing plate 2 and the inertial navigation device body 1.

[0026] In order to achieve a buffering function between the palm of the staff and the connecting rod 7, the utility model has a sponge layer 18 fixedly sleeved on the outer surface of the connecting rod 7. The thickness of the sponge layer 18 is set to two millimeters. Since the texture of the sponge layer 18 is relatively soft, a buffering function is achieved between the palm of the staff and the connecting rod 7.

[0027] In order to facilitate the staff to insert the limit rod 10 into the interior of the second limit hole 4, the utility model sets the number of the second limit holes 4 to two groups, and the inner diameters of the two groups of second limit holes 4 are adapted to the outer diameter of the limit rod 10, which facilitates the staff to insert the limit rod 10 into the interior of the second limit hole 4.

[0028] 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.

[0029] When in use, due to the provision of the heat dissipation holes 16, the heat generated inside the inertial navigation device body 1 can be discharged to avoid damage to the internal components of the inertial navigation device body 1 due to excessive temperature. When the staff needs to carry the device, the staff controls the hand-held block 12 to drive the moving block 11 and the limiting rod 10 to move inward along the inside of the fixed rod 8. At the same time, the moving block 11 drives the short rod 13 to squeeze the return spring 14 inward until the limiting rod 10 is moved out of the first limiting hole 3, thereby releasing the fixation between the connecting plate 6 and the fixing plate 2, and then controls the connecting plate 6 to drive the fixing rod 8 and the connecting plate 2 along the outer surface of the fixed shaft 5. The rod 7 and the sponge layer 18 are rotated ninety degrees to the front side, so that the fixed rod 8 drives the limiting rod 10 to move to a position horizontal to the second limiting hole 4, and then the control of the hand-held block 12 is released. At the same time, the reaction force generated by the compression of the reset spring 14 can drive the movable block 11 and the limiting rod 10 to move outward along the inside of the fixed rod 8 until the limiting rod 10 is inserted into the inside of the second limiting hole 4, and the connecting plate 6 and the fixing plate 2 can be re-fixed. Then the staff holds the connecting rod 7 and the sponge layer 18 with one hand, and then applies an upward pulling force to the device to lift the inertial navigation device body 1, and then the staff can carry the device.
