Description

Technical Field

[0001] The utility model relates to the technical field of fiber optic gyroscopes, in particular to a fiber optic gyroscope housing. Background Art

[0002] The fiber optic gyroscope is a sensitive element based on an optical fiber coil. The light emitted by the laser diode propagates in two directions along the optical fiber. The change in the light propagation path determines the angular displacement of the sensitive element. Compared with the traditional mechanical gyroscope, the fiber optic gyroscope has the advantages of being fully solid-state, without rotating parts and friction parts, long life, large dynamic range, instant start, simple structure, small size, and light weight. Compared with the laser gyroscope, the fiber optic gyroscope has no locking problem, and does not need to precisely machine the optical path on the quartz block, so the cost is low. The fiber optic gyroscope consists of an outer shell and an internal optical fiber coil. The shell of the fiber optic gyroscope mainly plays a role in protecting the internal optical fiber coil. The following problems exist in the prior art:

[0003] Because the shell of the fiber optic gyroscope is mainly composed of a protective cover and a base, when installing it, you only need to install the optical fiber coil on the base, and then install the protective cover on the base. However, the existing shell protective cover and the shell base need to be positioned and tightened at the four corners by four bolts to complete the fixation. Whenever the optical fiber coil inside the shell needs to be inspected, the four bolts need to be disassembled with the help of a screwdriver. The disassembly and assembly steps are cumbersome, and the disassembled bolts are easy to lose. Utility Model Content

[0023] When assembling the fiber optic gyroscope shell, the mounting blocks 121 on the left and right sides of the cylindrical frame 11 are aligned with the two fixed slots 212 on the top of the base plate 21 by using the fixed plug-in block 122 at the bottom to be inserted for positioning, and then the disassembly knobs 1213 on the front sides of the two mounting blocks 121 are rotated at the same time, so that the positive and negative threaded rods 1212 in the control cabin 1211 can be driven to rotate, so that the two movable suspension rods 1214 on the oppositely threaded outer walls arranged on the front and rear sides of the positive and negative threaded rods 1212 move forward and backward, thereby driving the positioning card plate 1221 in the fixed plug-in block 122 to move toward the front and rear sides of the fixed plug-in block 122 , until the front and rear sides of the fixed plug block 122 are moved out and snapped into the positioning grooves 213 on the front and rear sides of the inner wall of the fixed slot 212, the fixed plug block 122 is limited, and the cylindrical frame 11 and the base plate 21 are completely combined. When the optical fiber coil in the cylindrical frame 11 needs to be inspected, the disassembly and assembly knobs 1213 on the front sides of the two mounting blocks 121 can be directly reversed to drive the forward and reverse threaded rods 1212 to reverse, so that the movable suspension rod 1214 drives the positioning card plate 1221 to move closer to each other, disengage from the positioning grooves 213 on the front and rear sides of the inner wall of the fixed slot 212 to release the limit, and then the cylindrical frame 11 can be directly removed.

[0024] like Figure 5 As shown, the positioning ring body 22 includes an annular plate 221, and a rubber ring 222 is fixedly installed on the outer ring of the annular plate 221.

At the same time, after the cylindrical frame 11 is clamped with the positioning ring body 22, several heat dissipation holes 111 on the front and rear sides of the cylindrical frame 11 and the ventilation holes 223 on the front and rear sides of the annular plate 221 will all be connected, thereby facilitating the heat dissipation inside the cylindrical frame 11.

[0026] The working principle of the fiber optic gyroscope housing is described in detail below.

[0027] like Figure 1-5 As shown, when assembling the fiber optic gyroscope shell, the mounting blocks 121 on the left and right sides of the cylindrical frame 11 are aligned with the two fixed slots 212 on the top of the base plate 21 by using the fixed plug-in block 122 at the bottom to be snapped into position, and then the disassembly and assembly knobs 1213 on the front sides of the two mounting blocks 121 are rotated at the same time, so that the positive and negative threaded rods 1212 in the control cabin 1211 can be driven to rotate, so that the two movable suspension rods 1214 on the oppositely threaded outer walls set on the front and rear sides of the positive and negative threaded rods 1212 move forward and backward, thereby driving the positioning card plate 1221 in the fixed plug-in block 122 to move toward the front and rear sides of the fixed plug-in block 122, until it moves out of the front and rear sides of the fixed plug-in block 122 and snaps into the positioning grooves 213 on the front and rear sides of the inner wall of the fixed slot 212, completing the limiting of the fixed plug-in block 122, so that the cylindrical frame 11 and the base plate 21 are completely assembled, and when the cylindrical frame 11 is assembled with the base plate 21, it will be snapped. On the positioning ring body 22, the rubber ring 222 on the outer ring of the annular plate 221 is used to make the insertion more stable, thereby facilitating the rotation and tightening of the disassembly knob 1213. At the same time, after the cylindrical frame 11 is connected to the positioning ring body 22, the several heat dissipation holes 111 on the front and rear sides of the cylindrical frame 11 and the vent holes 223 on the front and rear sides of the annular plate 221 will all be connected, thereby facilitating the heat dissipation inside the cylindrical frame 11. Finally, the four mounting holes 211 on the base plate 21 can be directly used to install and fix the cylindrical frame 11. When the optical fiber coil in the cylindrical frame 11 needs to be inspected, the disassembly knobs 1213 on the front sides of the two mounting blocks 121 can be directly reversed to drive the forward and reverse threaded rods 1212 to reverse, so that the movable suspension rod 1214 drives the positioning card plate 1221 to move closer to each other, and the positioning grooves 213 on the front and rear sides of the inner wall of the fixed slot 212 are released to release the limit, and then the cylindrical frame 11 can be directly removed.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
