Description

Technical Field

[0001] This utility model relates to the field of fiber optic delay line equipment, specifically a precision adjustable microwave fiber optic delay line device. Background Technology

[0002] As a key component in optical information processing technology, fiber optic delay lines have multiple signal processing functions. The principle is that when an optical signal propagates in a medium, the change in the free optical path causes a time delay in the optical signal. The delay time is proportional to the length of the free optical path. Existing adjustment methods increase the friction between the sliding structure and the fixed structure, making precise adjustment impossible.

[0003] According to the patent document CN117891027A, a high-precision, fast-response adjustable fiber optic delay line includes a housing, which is barrel-shaped; a transmitter fixed to the end of the housing for transmitting and receiving light; a reflector slidably disposed within the housing for reflecting light emitted from the transmitter; and a drive unit disposed at the end of the housing away from the transmitter for driving the reflector to move. In this technical solution, the slider is connected to the drive unit, and the reflector is fixed to the slider. The movement of the drive unit can drive the slider to move, thereby driving the reflector to move, which facilitates the adjustment of the distance between the reflector and the transmitter. However, although this technical solution achieves distance adjustment, it does not allow for quick opening of the device for subsequent maintenance during position adjustment, which is inconvenient in use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a precision adjustable microwave fiber delay line device to solve the problems mentioned in the background technology. This utility model has a novel structure. In use, the fine adjustment rod moves out from the inside of the slot. The up and down movement of the fine adjustment rod completes the adjustment of the distance between the transmitter and the reflector. When the fine adjustment rod loses its limit on the movable plate, the movable plate moves to the side to achieve quick opening, which facilitates later maintenance.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precision adjustable microwave fiber delay line device, including a fixed box, a movable plate movably mounted on the top of the fixed box, a sliding groove opened on the side of the fixed box, a tension mechanism fixed inside the sliding groove, a slider fixed at one end of the tension mechanism, a movable frame fixed on the slider, an opening opened on the movable frame, a movable plate movably mounted inside the opening, a sealing gasket fixed on the inner wall of the opening, and a lifting mechanism fixedly mounted on the movable frame.

[0006] Furthermore, a fine-tuning rod is fixedly installed on the lifting mechanism, and a fixing column is fixedly installed between the fine-tuning rods.

[0007] Furthermore, a transmitter is fixed to one end of the fixed box, and a cable is fixedly installed on the transmitter.

[0008] Furthermore, the movable plate has a slot, which is movable in conjunction with a fine-tuning rod, and a fixing frame is fixed on the inner wall of the movable plate.

[0009] Furthermore, a limiting groove is formed on the inner wall of the fixed box, and a support mechanism is fixed inside the limiting groove. A limiting block is fixed at one end of the support mechanism, and the limiting block moves to cooperate with the fixed frame.

[0010] Furthermore, a positioning component is fixedly installed inside the fixed box, and a movable seat is fixedly installed at one end of the positioning component.

[0011] Furthermore, a fixing block is fixed to the bottom of the movable seat, one end of the fixing block is in contact with the inner wall of the fixed box, and a damper is fixedly installed on the fixing block.

[0012] Furthermore, a reset mechanism is movably mounted on the side of the damper, and a reflector is mounted on the movable seat, which cooperates with the transmitting end.

[0013] The beneficial effects of this utility model are:

[0014] This precision adjustable microwave fiber optic delay line device allows for the adjustment of the distance between the transmitter and the reflector by moving the fine adjustment rod out of the slot during use. When the fine adjustment rod loses its limit on the movable plate, the movable plate moves to the side to achieve rapid opening, facilitating subsequent maintenance.

[0015] This precision adjustable microwave fiber delay line device has a movable frame that loses its fixing force after the fine adjustment rod is moved out of the slot. The pulling mechanism drives the slider to move the movable frame to one end of the fixed box. The movable frame moves without limiting the movable plate, which facilitates the removal of the movable plate later.

[0016] This is a precision adjustable microwave fiber optic delay line device. The lifting mechanism controls the up and down movement of the fine adjustment rod. The up and down movement of the fine adjustment rod is supported by the inclined plane. The lifting mechanism can adjust the distance to the millimeter. Precise micro-adjustment can be achieved by controlling the fine adjustment rod through the lifting mechanism. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a precision adjustable microwave fiber delay line device, including a fixed box 1, a movable plate 2 movably mounted on the top of the fixed box 1, a sliding groove 5 on the side of the fixed box 1, a tension mechanism 6 fixed inside the sliding groove 5, a slider 12 fixed at one end of the tension mechanism 6, a movable frame 3 fixed on the slider 12, an opening on the movable frame 3, the movable plate 2 movably mounted inside the opening, a sealing gasket fixed on the inner wall of the opening, a lifting mechanism 4 fixedly mounted on the movable frame 3, a fine adjustment rod 10 fixedly mounted on the lifting mechanism 4, a fixed column 11 fixedly mounted between the fine adjustment rods 10, the lifting mechanism 4 is a linear reciprocating electric push rod, the lifting mechanism 4 pushes the fine adjustment rod 10 up and down to complete the adjustment of the position of the reflector 18.

[0024] In this embodiment, a transmitter 7 is fixed to one end of the fixed box 1, and a cable 8 is fixedly installed on the transmitter 7. A slot 9 is opened on the movable plate 2, and the slot 9 is movable and cooperates with the fine adjustment rod 10. A fixed frame 13 is fixed on the inner wall of the movable plate 2. A limit groove 14 is opened on the inner wall of the fixed box 1. A support mechanism 16 is fixed inside the limit groove 14. A limit block 15 is fixed to one end of the support mechanism 16. The limit block 15 is movable and cooperates with the fixed frame 13. Both the support mechanism 16 and the tension mechanism 6 are springs. The support mechanism 16 pushes the limit block 15 to move, and the limit block 15 pushes the movable frame 3 to move outward from the inside of the fixed box 1, so that the fixed frame 13 loses its limit on the movable plate 2.

[0025] In this embodiment, a positioning component 22 is fixedly installed inside the fixed box 1. A movable seat 17 is fixedly installed at one end of the positioning component 22. A fixing block 19 is fixed at the bottom of the movable seat 17. One end of the fixing block 19 contacts the inner wall of the fixed box 1. A damper 20 is fixedly installed on the fixing block 19. A reset mechanism 21 is movably installed on the side of the damper 20. A reflector 18 is installed on the movable seat 17. The reflector 18 cooperates with the transmitting end 7. The reset mechanism 21 is a reset spring. The reset spring pushes the fixing block 19 and the movable seat 17 to move horizontally and vertically to complete the subsequent adjustment.

[0026] When in use, the lifting mechanism 4 is activated to push the fine-tuning rod 10 up and down inside the slot 9. The millimeter-level movement of the fine-tuning rod 10 adjusts the inclined plane to the support point of the movable seat 17. As the support point moves, the movable seat 17 moves towards the positioning assembly 22. The movement of the movable seat 17 changes the distance between the reflector 18 and the transmitter 7, controlling the stopping position of the reflector 18, i.e., the delay of the fiber optic delay line. The positioning assembly 22 includes a positioning post and a positioning tube. The movable seat 17 moves horizontally inside the positioning tube via the positioning post. The power source for the movement of the movable seat 17 is... Provided by the reset mechanism 21 and the damper 20, the damper 20 and the reset mechanism 21 provide secondary limit support for the horizontal movement of the movable seat 17. Later, when the fine adjustment rod 10 is moved out of the slot 9, the limit block 15 pushes the fixed frame 13 to move under the drive of the support mechanism 16. The movable frame 3 loses its fixing force, and the pulling mechanism 6 drives the slider 12 to move towards the launching end 7. The movable frame 3 loses its limit on the movable plate 2. After the movable plate 2 moves upward, it is removed, and the space inside the fixed box 1 is opened, which facilitates the quick maintenance and use of the internal equipment.
