Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber gyroscopes, in particular to a high-strength optical fiber gyroscope support frame. Background Art

[0002] Fiber optic gyroscope is a fiber optic angular velocity sensor, which is the most promising type of fiber optic sensor. Like the ring laser gyroscope, the fiber optic gyroscope has the advantages of no mechanical moving parts, no warm-up time, insensitivity to acceleration, wide dynamic range, digital output, and small size.

[0003] However, the current fiber optic gyroscope skeleton is an integrated hard shell structure. When subjected to external pressure or impact, there is no buffering measure and the shell is prone to rupture. Therefore, we propose a high-strength fiber optic gyroscope support skeleton to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength fiber optic gyroscope support frame to solve the problem that the existing fiber optic gyroscope frame proposed in the above background technology is an integrated hard shell structure, and when it is subjected to external pressure or impact, there is no buffering measure and the shell is prone to rupture.

[0005] To achieve the above object, the utility model provides the following technical solutions: a high-strength fiber optic gyroscope support frame, comprising a positioning base plate, a lower shell seat is installed on the upper end of the positioning base plate, and the lower shell seat is welded to the positioning base plate;

[0006] Also includes:

[0007] An upper shell cover, which is arranged at the upper end of the lower shell seat, and the upper shell cover is slidably connected to the lower shell seat;

[0008] A component installation cavity is arranged inside the lower shell seat, and damping rods are installed at the four corners of the component installation cavity. The upper end of the damping rod is fixedly connected to the positioning base plate through a damping rod fixing seat, and a shock absorbing spring is installed on the outer wall of the damping rod;

[0009] A lead through hole is arranged on the outer wall of the lower shell seat.

[0010] Preferably, an elastic sealing ring is installed at the edge of the upper end of the lower shell seat.

[0011] Preferably, a rubber anti-collision sleeve is provided on the outer wall of the upper shell cover.

[0012] Preferably, triangular reinforcement plates are installed around the outer wall of the lower shell seat, and four triangular reinforcement plates are provided.

[0013] Preferably, an auxiliary damping block is provided at the upper end of the triangular reinforcement plate.

[0014] Preferably, mounting through holes are provided inside the four corners of the positioning base plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the utility model is in use, since the upper shell cover and the lower shell seat are sliding structures, when the outside of the frame is subjected to pressure impact, the upper shell cover can move down along the lower shell seat, and the damping rods and shock-absorbing springs at the four corners of the cavity are installed in coordination with the components to absorb the impact force to a certain extent, thereby achieving the effect of shock-absorbing protection and preventing the shell from breaking. This solves the problem that the existing fiber optic gyroscope frame is an integrated hard shell structure, and when it is subjected to external pressure or impact, there is no buffering measure, and the shell is prone to breakage.

[0017] 2. The utility model arranges four sets of triangular reinforcement plates around the lower shell seat. On the one hand, the triangular reinforcement plates have good structural stability and improve the structural strength of the lower shell seat. On the other hand, when the upper shell cover moves downward under the pressure of external force, its edge touches the triangular reinforcement plates. The triangular reinforcement plates can limit the edge of the upper shell cover through the auxiliary damping blocks on the top to avoid excessive contraction of the damping rod, which may cause excessive deformation and disability of the shock-absorbing spring.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-3 The utility model provides an embodiment: a high-strength fiber optic gyroscope support frame, including a positioning base plate 1, a lower shell seat 2 is installed on the upper end of the positioning base plate 1, and the lower shell seat 2 is welded to the positioning base plate 1;

[0024] Also includes:

[0025] An upper shell cover 3 is arranged at the upper end of the lower shell base 2, and the upper shell cover 3 is slidably connected to the lower shell base 2;

[0026] The component installation cavity 12 is arranged inside the lower housing seat 2, and damping rods 9 are installed at the four corners inside the component installation cavity 12. The upper end of the damping rod 9 is fixedly connected to the positioning base plate 1 through the damping rod fixing seat 4, and a shock absorbing spring 10 is installed on the outer wall of the damping rod 9;

[0027] The lead wire through hole 5 is arranged on the outer wall of the lower shell base 2 .

[0028] See also Figure 3 An elastic sealing ring 13 is installed at the edge of the upper end of the lower shell seat 2. Since the lower shell seat 2 and the upper shell cover 3 are sliding structures, the setting of the elastic sealing ring 13 ensures the sealing performance of the connection between the lower shell seat 2 and the upper shell cover 3.

[0029] See also Figure 1 A rubber anti-collision sleeve 11 is arranged on the outer wall of the upper shell cover 3 , and the arrangement of the rubber anti-collision sleeve 11 further improves the anti-collision performance of the upper shell cover 3 .

[0030] See also Figure 1 and Figure 2 The outer wall of the lower shell seat 2 is surrounded by triangular reinforcement plates 7, and four triangular reinforcement plates 7 are provided. The triangular reinforcement plates 7 have good structural stability and improve the structural strength of the lower shell seat 2.

[0031] See also Figure 2 An auxiliary damping block 8 is provided at the upper end of the triangular reinforcement plate 7. When the upper shell cover 3 moves downward under the pressure of external force, after its edge touches the triangular reinforcement plate 7, the triangular reinforcement plate 7 can limit the edge of the upper shell cover 3 through the auxiliary damping block 8 on the top to avoid excessive contraction of the damping rod 9, which will cause excessive deformation and disability of the shock-absorbing spring 10.

[0032] See also Figure 1 The four corners of the positioning base plate 1 are each provided with mounting through holes 6, and the positioning base plate 1 is fixed to the mounting surface through the mounting through holes 6 and screws.

[0033] Working principle: When in use, the fiber optic gyroscope shell skeleton can be fixed to the mounting surface through the mounting through holes 6 and screws at the four corners of the bottom positioning base plate 1. When in use, because the upper shell cover 3 and the lower shell seat 2 are sliding structures, when the outside of the skeleton is subjected to pressure impact, the upper shell cover 3 can move down along the lower shell seat 2, and cooperate with the damping rods 9 and shock-absorbing springs 10 at the four corners of the component installation cavity 12 to absorb the impact force to a certain extent, thereby achieving the effect of shock-absorbing protection. Four groups of triangular reinforcement plates 7 are arranged around the lower shell seat 2. On the one hand, the triangular reinforcement plates 7 have good structural stability and improve the structural strength of the lower shell seat 2. On the other hand, when the upper shell cover 3 moves downward under the pressure of external force, after its edge touches the triangular reinforcement plate 7, the triangular reinforcement plate 7 can limit the edge of the upper shell cover 3 through the auxiliary damping block 8 on the top to avoid excessive contraction of the damping rod 9, which causes excessive deformation and disability of the shock-absorbing spring 10.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
