Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an optical fiber loss testing device. Background Art

[0002] After the pipeline is bent, the transmission light inside the optical fiber core can no longer be transmitted under the condition of total reflection, resulting in a certain amount of loss. Therefore, it is necessary to test the optical fiber bending loss. Traditional testing equipment requires manual movement of the light source after the angle of the optical fiber is changed, which makes operation inconvenient.

[0003] Prior art CN218381541U discloses an optical fiber bending loss test device, comprising a plate body and a bending cylinder. The plate body is mounted with a power meter. The bending cylinder is arranged parallel to one side of the power meter and can be guided and moved along the thickness direction of the plate body. The cylinder body is provided with at least two grooves of different depths from top to bottom. The grooves are concentric and coaxial with the bending cylinder and are used to change the orientation of the optical fiber connected to the power meter. The utility model allows the cable clamp that fixes the light source to rotate in a regular circular motion. When it is necessary to test the bending loss of the optical fiber at different angles, only the position of the cable clamp needs to be changed to easily achieve the angle change of the optical fiber. The orientation of the optical fiber point connected to the light source remains unchanged, avoiding the variable factors caused by changes in the angle and position of the optical fiber during the test.

[0004] The above device can conveniently adjust the angle of the light source. At the same time, by adjusting the height of the cylinder, the optical fiber can enter different grooves to adjust the degree of tension of the optical fiber, avoiding excessive or insufficient tension of the optical fiber. However, the process of adjusting the cylinder needs to be performed manually, which is cumbersome and reduces test efficiency. Utility Model Content

[0020] See also Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the optical fiber loss test device. Figure 2 It is a structural diagram of the regulating component. Figure 3 yes Figure 2 Enlarged view of point A.

[0021] The present invention provides an optical fiber loss test device, including a workbench 101 and an adjustment assembly 102, wherein the adjustment assembly 102 includes a mounting tube 103, a lifting seat 104, a winding cone 105, a sliding seat 106, a mounting plate 107, a driving member 108, a clamping member 109 and a guide rod 114, and the driving member 108 includes a connecting rod 110, a driving ball 111, a driving seat 112 and a tension spring 113. The optical fiber is bent by rotating the mounting plate 107, and the sliding seat 106 is rotated during the rotation of the mounting plate 107, thereby driving the driving member 108 to move, so that the driving member 108 drives the lifting seat 104 and the winding cone 105 to descend, thereby preventing the optical fiber from being too tight or loose during the bending process, and achieving the purpose of conveniently adjusting the tension of the optical fiber and improving the measurement efficiency. It can be understood that the above-mentioned scheme can be used to facilitate the adjustment of the tension of the optical fiber and improve the measurement efficiency, and can also be used to solve the problem of clamping the optical fiber.

[0022] According to this specific embodiment, two adjustment components 102 are provided, two slide grooves are provided on the workbench 101 to cooperate with the two sliding seats 106 , and two power meters 115 are also installed on the workbench 101 .

[0023] Among them, the mounting cylinder 103 is fixedly connected to the workbench 101 and is located on one side of the workbench 101. The lifting seat 104 is slidably connected to the mounting cylinder 103 and is located inside the mounting cylinder 103. The winding cone 105 is fixedly connected to the lifting seat 104 and is located at one end of the lifting seat 104. The sliding seat 106 is slidably connected to the workbench 101 and is set on the workbench 101. The mounting plate 107 is fixedly connected to the sliding seat 106 and is set on the sliding seat 106. The driving member 108 is arranged on the sliding seat 106, and the clamping member 109 is arranged on the mounting plate 107; the winding cone 105 is conical, and its diameter gradually increases from top to bottom. The driving member 108 can drive the lifting seat 104 to move up and down, and the clamping member 109 can clamp the optical fiber. The mounting plate 107 is also provided with a light source 116. The sliding seat 106 can slide in the slide groove on the workbench 101, thereby driving the mounting plate 107 to rotate with the winding cone 105 as the center of the circle; when in use, One end of the optical fiber is connected to the power meter 115, and the other end of the optical fiber is clamped and fixed by the clamping member 109 and connected to the light source 116. First, the optical fiber is not bent, and the input and output powers of the optical fiber are measured by the power meter 115. Then, by rotating the mounting plate 107, the light source 116 and one end of the optical fiber are driven to rotate, so that the optical fiber is bent. At this time, the light source 116 is turned on to measure the input power and output power of the optical fiber again, so as to calculate the loss. When the mounting plate 107 rotates, the driving member 116 is driven to rotate. 08 rotates, so that the driving member 108 drives the lifting seat 104 to descend, thereby driving the winding cone 105 to descend, so that the winding cone 105 descends during the bending process of the optical fiber, thereby reducing the diameter of the part of the winding cone 105 in contact with the optical fiber, thereby avoiding excessive tension of the optical fiber during the bending process; when the bending angle of the optical fiber is reduced, the driving member 108 drives the lifting seat 104 and the winding cone 105 to rise, thereby tightening the optical fiber, realizing automatic adjustment of the tensioning length of the optical fiber, and avoiding the problem of cumbersome operation caused by manual adjustment.

[0024] Secondly, the connecting rod 110 is fixedly connected to the sliding seat 106 and is located on one side of the sliding seat 106; the driving ball 111 is fixedly connected to the connecting rod 110 and is located at the end of the connecting rod 110 away from the sliding seat 106; the driving seat 112 is fixedly connected to the lifting seat 104, abuts against the driving ball 111, and is located on one side of the lifting seat 104.

[0025] At the same time, both ends of the tension spring 113 are connected to the lifting seat 104 and the installation tube 103 respectively, and the tension spring 113 is located inside the installation tube 103 .

[0026] The driving seat 112 is provided with an inclined surface, and the driving ball 111 abuts against the inclined surface on the driving seat 112. When the mounting plate 107 rotates, it drives the sliding seat 106 to rotate, so that the sliding seat 106 drives the connecting rod 110 and the driving ball 111 to rotate, and then the driving ball 111 moves along the inclined surface on the driving seat 112. At this time, the driving seat 112 and the lifting seat 104 descend under the action of the tension spring 113, so that the driving seat 112 always abuts against the driving ball 111; the same applies when the mounting plate 107 rotates in the opposite direction, thereby achieving the purpose of driving the lifting seat 104 to move up and down.

[0027] In addition, the guide rod 114 is fixedly connected to the mounting tube 103 and slidably connected to the lifting seat 104, and is located inside the mounting tube 103; the lifting seat 104 is guided by the guide rod 114, so that the lifting seat 104 can only be lifted in the vertical direction, thereby preventing the lifting seat 104 from rotating and driving the driving seat 112 to rotate, affecting the lifting and lowering of the winding cone 105.

[0028] When using the optical fiber loss testing device of this embodiment, when the mounting plate 107 rotates, it drives the sliding seat 106, the light source 116 and one end of the optical fiber to rotate, thereby bending the optical fiber; while the sliding seat 106 rotates, it also drives the connecting rod 110 to rotate, and then the connecting rod 110 drives the driving ball 111 to rotate, so that the driving seat 112 rises and falls under the action of the driving ball 111 and the tension spring 113, so that when the bending angle of the optical fiber increases, the winding cone 105 descends, and when the bending angle of the optical fiber decreases, the winding cone 105 rises, thereby facilitating the adjustment of the tension of the optical fiber and improving the measurement efficiency.

[0030] Based on the first embodiment, please refer to Figure 4 , Figure 42 is a schematic diagram of the installation structure of the bidirectional screw of the second embodiment. The clamping member 109 of this embodiment includes a bidirectional screw 201 and a clamping plate 202.

[0031] According to this specific embodiment, the bidirectional screw 201 is rotatably connected to the mounting plate 107 and is located inside the mounting plate 107; the clamping plate 202 is slidably connected to the mounting plate 107, and is threadedly connected to the bidirectional screw 201, and is sleeved on the bidirectional screw 201; a knob is also installed at one end of the bidirectional screw 201, and the thread directions on both sides of the bidirectional screw 201 are opposite. There are two clamping plates 202, which are respectively located on both sides of the bidirectional screw 201.
