[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a fixed-length fixture for stripping optical fibers, including a fixed base 1 and an adjusting base 2. The fixed base 1 is provided with a first channel 3. The adjusting base 2 is arranged opposite to the fixed base 1 and is provided with a second channel 4. The first channel 3 is provided with a mounting groove 20. The mounting groove 20 has rectangular openings 21 on both sides that communicate with the outside. An upper cutting seat 5 and a lower cutting seat 17 are arranged one above the other in the mounting groove 20. Pressure blocks 6 are installed on both sides of the upper cutting seat 5 and the lower cutting seat 17 facing the rectangular openings 21. The other end of each pressure block 6 passes through the rectangular openings 21. The fixed base 1 has compression plates 12 on both sides that drive the pressure blocks 6 to move inward. The upper cutting seat 5 is provided with a fixing plate 7 on its outside. Multiple connecting rods 10 are installed on the fixing plate 7. The other end of each connecting rod 10 is installed on the fixing base 1 through a hinge. Each fixing plate 7 is provided with an elastic component connected to the upper cutting seat 5.
[0022] In this embodiment, the elastic component includes a positioning post, a hand-tightening bolt 9, and a compression spring 8. The middle of the fixing plate 7 is provided with a positioning hole. One end of the positioning post passes through the positioning hole and is installed on the upper cutting seat 5. The other end of the positioning post is provided with a screw hole. The hand-tightening bolt 9 is threaded into the screw hole. The compression spring 8 is sleeved on the outside of the positioning post. One end of the compression spring 8 abuts against the fixing plate 7, and the other end abuts against the end of the hand-tightening bolt 9.
[0023] During disassembly, the hand-tightening bolt can be rotated. After the hand-tightening bolt is unscrewed from the screw hole, the compression spring can be removed, and the upper cutting seat can be lifted up so that the positioning pin can be taken out along the positioning port. After the upper cutting seat is no longer obstructed, the lower cutting seat can be poured out directly from the mounting slot to complete the replacement of the two.
[0024] In this embodiment, the opposite side of the pressure block 6 is provided with a first guide section at an inclination, and one end of the extrusion plate 12 forms a second guide section with a figure-eight structure. The second guide section is in contact with the first guide section. The fixed seat 1 is provided with a longitudinal plate at the end away from the adjustment seat 2. Multiple horizontal plates 11 are installed between the longitudinal plate and the extrusion plate 12. A first push block 13 is installed at one end of the longitudinal plate, and a second push block 14 is installed on the fixed seat 1.
[0025] In this embodiment, the fixed base 1 is provided with a guide groove at the end away from the adjusting base 2, and a guide plate 16 is movably arranged in the guide groove. One end of the guide plate 16 extends to the outside and is installed on the longitudinal plate, so that the first push block can only move stably along the guide groove, avoiding the situation of deviation.
[0026] In this embodiment, the fixed base 1 is provided with an adjustment groove at one end facing the adjustment base 2. An adjustment plate 15 is movably arranged in the adjustment groove. One end of the adjustment plate 15 extends to the outside and is installed on the adjustment base 2. A rubber layer is embedded in the inner wall of the adjustment groove and is in frictional contact with the adjustment plate 15.
[0027] The rubber layer increases the damping effect between the adjustment plate and the adjustment groove, thereby positioning the moved adjustment seat to change the length during cutting.
[0028] In this embodiment, grooves 19 are provided on the opposite surfaces of the upper cutting seat 5 and the lower cutting seat 17, and blades 18 for cutting optical fibers are longitudinally installed on the grooves 19.
[0029] The upper cutting seat has an arc-shaped surface at the end away from the adjustment seat. Therefore, after the connecting rod is lifted with the hinge as the center, the fixing plate and the upper cutting seat can be driven simultaneously. The arc-shaped surface allows the upper cutting seat to be lifted smoothly. After being lifted, the optical fiber can be put into the first channel, and one end of the light can enter the second channel until it contacts the end face of the second channel.
[0030] The stripping length can be controlled by changing the position of the adjusting seat. After the above is completed, the connecting rod is pressed down to make the upper cutting seat enter the mounting groove. At this time, the thumb is pressed against the outside of the first push block and the index finger is pressed against the outside of the second push block. After applying force inward, the horizontal plate and the extrusion plate can be moved. The second guide part can squeeze the first guide part, so that the pressure block can drive the upper cutting seat and the lower cutting seat to move inward along the inner wall of the mounting groove to complete the cutting operation.
[0031] When the upper cutting seat moves, it can compress the spring. Therefore, after the extrusion plate returns to its original position, the upper cutting seat can be automatically lifted by the rebound of the compression spring, and the upper cutting seat can also be opened smoothly so that the optical fiber can be taken out smoothly, avoiding contact with the blade on the upper cutting seat.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
