DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1 - 3 shown, an embodiment of the present utility model provides a fiber optic angular velocity sensor that is easy to assemble, including:

[0021] A lower cover 1 and an upper cover 4, and a velocity sensor is installed inside the lower cover 1;

[0022] A connecting mechanism; the connecting mechanism includes four first mounting blocks 3 fixed to the lower cover 1 and four second mounting blocks 5 fixed to the upper cover 4. Both the lower cover 1 and the upper cover 4 are circular in shape. The four first mounting blocks 3 are integrally formed with the lower cover 1, and the four first mounting blocks 3 are arranged in a circular array on the lower cover 1; the second mounting blocks 5 are integrally formed with the upper cover 4, and the four second mounting blocks 5 are arranged in a circular array on the upper cover 4 and are correspondingly arranged with the first mounting blocks 3.

[0023] The upper end of the lower cover 1 is provided with an annular groove 2, and a rubber sealing ring 9 is installed in the annular groove 2. A connecting ring 13 is fixed to the bottom of the upper cover 4. When the upper cover 4 is installed on the lower cover 1, the connecting ring 13 slides in the annular groove 2 and presses the sealing ring 9, so as to ensure the sealing performance between the upper cover 4 and the lower cover 1.

[0024] The upper end of the first mounting block 3 is provided with a mounting groove 6. Two blocking blocks 7 are fixed to the inner wall of the mounting groove 6. The upper ends of the two blocking blocks 7 are flush with the upper end of the lower cover 1, and there is a gap between the two blocking blocks 7. The width of the gap is slightly larger than the thickness of the connecting block 11. Here, the slightly larger means slightly larger. The connecting block 11 can slide between the two blocking blocks 7.

[0025] A connecting block 11 is fixed to the bottom of the second mounting block 5, and a limiting block 10 is fixed to the bottom of the connecting block 11. The width of the mounting groove 6 is matched with the width of the limiting block 10, that is to say, the limiting block 10 can be installed in the mounting groove 6 and move; the limiting block 10 is slidably installed in the mounting groove 6 and abuts against the bottom of the blocking block 7. When the upper cover 4 is installed on the lower cover 1, in order to increase the friction between the upper cover 4 and the lower cover 1 and make it not easy to loosen, a plurality of first rubber particles 8 are fixed to the bottom of the blocking block 7, and a plurality of second rubber particles 12 are fixed to the upper end of the limiting block 10. When the upper cover 4 is installed on the lower cover 1, the first rubber particles 8 and the second rubber particles 12 are arranged in an alternating manner.

[0026] During installation, the limiting block 10 is placed in the mounting groove 6. At this time, the connecting ring 13 is slidably connected in the annular groove 2, and at this time, the connecting ring 13 abuts against the sealing ring 9. The staff manually installs the upper cover 4 and the lower cover 1 relatively. At this time, the sealing ring 9 is squeezed and deformed, and the relative movement between the upper cover 4 and the lower cover 1 can be realized. Then, the upper cover 4 and the lower cover 1 are rotated to make the limiting block 10 rotate to the inner side of the mounting groove 6, that is to say, the connecting block 11 is moved between the two blocking blocks 7 until the limiting block 10 abuts against the inner wall of the mounting groove 6 and cannot move. At this time, the first mounting block 3 and the second mounting block 5 are facing each other. The lower cover 1 and the upper cover 4 are released, and the sealing ring 9 is squeezed and reset, so that the upper cover 4 is away from the lower cover 1. At this time, between the limiting block 10 and the blocking block 7, and the first rubber particles 8 and the second rubber particles 12 are abutted against each other in an alternating manner, so as to realize the assembly of the upper cover 4 and the lower cover 1;

[0027] For the present utility model, only by installing the limiting block 10 in the mounting groove 6, relatively squeezing the upper cover 4 and the lower cover 1 and rotating until it cannot move, the assembly of the upper cover 4 and the lower cover 1 can be realized. It is simple and fast, without the need to use tools, and improves the assembly efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
