Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber loops, and particularly relates to a convenient installation and switching test platform for an optical fiber loop bare loop and a magnetic shielding encapsulation loop. Background Technique

[0002] With the large-scale application, development, and progress of fiber optic gyroscopes, the improvement of the comprehensive performance of fiber optic gyroscopes has become an important research focus. Among them, the stability of the optical fiber loop has become one of the important research focuses. The stability of the fiber optic gyroscope means that the fiber optic gyroscope has good zero-bias stability at normal temperature or certain fixed temperature environments. Existing research has shown that the zero-bias stability of the fiber optic gyroscope is most affected by optical components, especially the stability of the optical fiber loop. Therefore, it is necessary to test the performance of the zero-bias stability of the optical fiber loop at different temperatures before the optical fiber loop is encapsulated.

[0003] Currently, when testing the zero-bias performance of the optical fiber loop, the main body of the optical fiber loop is mainly placed on the test platform in the temperature control box. Since the test platform generally uses aluminum material and its heat conduction rate is too high, generally, a support seat is fixed on the test platform to support the bare loop of the optical fiber loop to be tested or the magnetic shielding encapsulation loop. However, because the types of support seats required for the bare loop of the optical fiber loop and the magnetic shielding encapsulation loop are different, when it is necessary to further test the magnetic shielding encapsulation loop after testing the bare loop of the optical fiber loop, the entire test platform in the temperature control box needs to be disassembled and replaced with a test platform specifically for testing the magnetic shielding encapsulation loop. Since the test platform is fixed to the support frame by multiple screws, the replacement process of the entire test platform is extremely cumbersome, and due to the large weight of the test platform, it is extremely inconvenient to replace. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a convenient installation and switching test platform for an optical fiber loop bare loop and a magnetic shielding encapsulation loop, and solves the technical problems that the replacement process of the entire test platform in the prior art is extremely cumbersome and it is extremely inconvenient to replace due to the large weight of the test platform.

[0005] The utility model is realized through the following technical solutions:

[0006] A convenient installation and switching test platform for an optical fiber loop bare loop and a magnetic shielding encapsulation loop includes a platform body, a first support seat for supporting the bare loop of the optical fiber loop, and a second support seat for supporting the magnetic shielding encapsulation loop. A plurality of grooves are distributed on the platform body. A plurality of first columns protrude from the side of the first support seat facing the platform body, and a plurality of second columns protrude from the side of the second support seat facing the platform body. The first columns and the second columns are all accommodated in the grooves.

[0007] Furthermore, the first support base includes a first main body portion, and the plurality of first columns are integrally formed on the first main body portion.

[0008] Furthermore, the first main body portion is in a circular ring shape.

[0009] Furthermore, the first support base further includes a plurality of first support feet evenly distributed along the direction of the first main body portion. The first support feet are integrally formed with the first main body portion and are used to support the bare fiber optic ring.

[0010] Furthermore, the first main body portion has an opening, and the first pigtail of the bare fiber optic ring passes through the opening and extends out of the platform body.

[0011] Furthermore, the second support base includes a pair of semi-circular fan-shaped pieces. The second columns protrude from the side of the fan-shaped pieces facing the platform body.

[0012] Furthermore, a gap is formed between the pair of fan-shaped pieces, and the second pigtail of the magnetic shielding encapsulation ring passes through the gap and extends out of the platform body.

[0013] Furthermore, the magnetic shielding encapsulation ring includes an upper shell, a lower shell, and an encapsulated bare ring. An installation space is formed between the upper shell and the lower shell, and the encapsulated bare ring is accommodated in the installation space.

[0014] Furthermore, the upper shell is provided with an opening through which the second pigtail passes.

[0015] Furthermore, the opening is directly above the gap.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] By designing the first support base and the second support base to be detachably connected to the platform body, when it is necessary to replace with different support bases, only the corresponding support base needs to be installed, which is simple and convenient to operate. This solves the technical problems in the prior art that the replacement process of the entire test platform is extremely cumbersome, and due to the large weight of the test platform, it is extremely inconvenient to replace.

[0025] The following further describes the technical solution of the utility model in detail and non-restrictively in conjunction with the preferred embodiments and their accompanying drawings. In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0026] As Figures 1-6As shown in the figure, a test platform for convenient switching between a bare optical fiber loop and a magnetically shielded encapsulation loop according to an embodiment of the present utility model is characterized by including a platform body 1, a first support seat 2 for supporting the bare optical fiber loop 4, and a second support seat 3 for supporting the magnetically shielded encapsulation loop 5. A plurality of grooves 10 are distributed on the platform body 1. On the side of the first support seat 2 facing the platform body 1, a plurality of first columns 20 protrude. On the side of the second support seat 3 facing the platform body 1, a plurality of second columns 30 protrude. The first columns 20 and the second columns 30 are both accommodated in the grooves 10. In the present utility model, by designing the first support seat 2 and the second support seat 3 to be detachably connected to the platform body 1, when it is necessary to replace with different support seats, only the corresponding support seat needs to be installed, and the operation is simple and convenient, solving the technical problems in the prior art that the replacement process of the entire test platform is extremely cumbersome, and due to the large weight of the test platform, it is extremely inconvenient to replace.

[0027] The first support seat 2 includes a first main body portion 21, and a plurality of first columns 20 are integrally formed on the first main body portion 21. Among them, the first main body portion 21 is in a circular ring shape. In this embodiment, the material of the first support seat 2 is bakelite.

[0028] The first main body portion 21 has an opening 210, and the first tail fiber 40 of the bare optical fiber loop 4 passes through the opening 210 and extends out of the platform body 1.

[0029] The first support seat 2 further includes a plurality of first support feet 22 evenly distributed along the direction of the first main body portion 21. The first support feet 22 are integrally formed with the first main body portion 21 for supporting the bare optical fiber loop 4. In this embodiment, the first support feet 22 are set to be 3 and are respectively located at both ends and the middle position of the first main body portion 21. The first support feet 22 are in contact with the platform body 1, and the thickness of the first support feet 22 is greater than the thickness of the first main body portion 21. Therefore, when the bare optical fiber loop 4 is placed on the first support seat 2, there is a gap between the first main body portion 21 and the bare optical fiber loop 4. The purpose of setting the first main body portion 21 is to improve the stability between the plurality of first support feet 22, and when disassembling or installing the first support seat 2, the plurality of first support feet 22 can be directly removed, and the entire installation or disassembly process is more convenient.

[0030] The second support seat 3 includes a pair of semi-circular fan blades 31, and the second columns 30 protrude on the side of the fan blades 31 facing the platform body 1. In this embodiment, the material of the second support seat 3 is aluminum alloy.

[0031] The pair of fan blades 31 are symmetrically distributed, and a gap 32 is formed between the pair of fan blades 31. The second tail fiber 54 of the magnetically shielded encapsulation loop 5 extends out of the platform body 1 through the gap 32.

[0032] The magnetic shielding encapsulation ring 5 includes an upper housing 50, a lower housing 51, and an encapsulated bare ring 52. An installation space 53 is formed between the upper housing 50 and the lower housing 51, and the encapsulated bare ring 52 is accommodated in the installation space 53.

[0033] The upper housing 50 is provided with an opening 500 for the second optical fiber stub 54 to pass through.

[0034] The opening 500 is directly above the gap 32. The purpose is to enable the second optical fiber stub 54 coming out of the opening 500 to extend out of the platform body 1 from the gap 32 without contacting the second support base 3.

[0035] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
