Such a detector is usually used for on-site testing to help technicians quickly diagnose problems in the optical fiber link and ensure the reliability and performance of the network.

[0003] Chinese Patent Publication No. CN218920430U, published on April 25, 2023, discloses a portable optical fiber tester, including: a fuselage and a protective plate; optical fiber interfaces are symmetrically arranged on the left and right sides of the fuselage, the protective plate is installed outside the optical fiber interfaces, and rubber-coated protrusions are installed around the protective plate; a wavy pattern is provided at the hand-held part of the outer wall of the fuselage; a wristband is provided on the side of the fuselage.

[0004] For example, the existing portable detector for testing the transmission performance of optical fibers realizes the test of the optical fiber transmission performance by connecting an external optical fiber connector to the optical fiber interface on the fuselage. In the specific implementation process, the optical fiber interface is mostly set in an exposed manner, and the optical fiber interface is prone to attaching impurities and being impacted by external forces, which in turn affects the normal use of the detector. Therefore, it is urgent to propose a corresponding portable detector for testing the transmission performance of optical fibers to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to: in order to solve the above problems, a portable detector for testing the transmission performance of optical fibers is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A protective frame fixedly connected to the fuselage is arranged outside the optical fiber interface. A top seat is fixedly connected to the top of the fuselage. A cross plate is slidably connected to the outer surface wall of the top seat. A sealing plate fixedly connected to the bottom of the cross plate is slidably connected to the inner surface wall of the protective frame. A positioning component for positioning the cross plate is arranged between the cross plate and the top seat.

[0008] Preferably, a reinforcing rod is screwed to the inner surface wall of the protective frame, and a rubber sleeve is sleeved on the open end of the reinforcing rod.

[0009] Preferably, the cross section of the sealing plate is in a rectangular structure, and the outer surface wall of the sealing plate is slidably connected to the inner surface wall of the top of the protective frame through a card slot.

[0010] Preferably, the positioning component includes a positioning rod, the outer surface of the positioning rod is screwed to the inner surface of the cross plate, and the open end of the positioning rod abuts against the outer surface of the top seat.

The cross plate drives the sealing plate until the top seat abuts against the bottom of the limiting piece. Rotate the positioning rod so that it is screwed to the inner surface of the cross plate, and the open end of the positioning rod abuts against the outer surface of the top seat, thereby realizing the fixation of the cross plate. At this time, the sealing plate cancels the shielding of the fiber optic interface, and connect the external fiber optic connector to the fiber optic interface, thus starting the test of the fiber optic transmission performance. Similarly, after the fiber optic performance test is completed, push the cross plate downward until its bottom abuts against the top of the mounting piece, and also fix the cross plate through the positioning rod. At this time, the sealing plate completely shields the outside of the fiber optic interface. At this time, the closed cover formed by the sealing plate and the protective frame can effectively protect the fiber optic interface.

In this application, after connecting the external fiber optic connector to the fiber optic interface on the fuselage, the reinforcing rod can be rotated so that it is screwed to the inner surface of the protective frame until the reinforcing rod abuts against the outer surface of the external fiber optic connector. The frictional force generated by the contact between the reinforcing rod and the external fiber optic connector can effectively limit the loosening of the fiber optic connector, thereby further improving the stability of the portable detector used for the fiber optic transmission performance test.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A portable detector for testing the performance of optical fiber transmission includes a body 1 and an optical fiber interface 2. A protective frame 3 fixedly connected to the body 1 is arranged outside the optical fiber interface 2. A top seat 7 is fixedly connected to the top of the body 1. A horizontal plate 5 is slidably connected to the outer surface of the top seat 7. A sealing plate 6 fixedly connected to the bottom of the horizontal plate 5 is slidably connected to the inner surface of the protective frame 3. A positioning component for positioning the horizontal plate 5 is arranged between the horizontal plate 5 and the top seat 7;

[0025] Move the horizontal plate 5 upward so that it slides along the outer surface of the top seat 7. The horizontal plate 5 drives the sealing plate 6 until the top seat 7 abuts against the bottom of the limiting piece 8. Rotate the positioning rod 9 so that it is screwed with the inner surface of the horizontal plate 5. The open end of the positioning rod 9 abuts against the outer surface of the top seat 7, thereby realizing the fixation of the horizontal plate 5. At this time, the sealing plate 6 cancels the shielding of the optical fiber interface 2. Connect the external optical fiber connector to the optical fiber interface 2, thereby starting the test of the optical fiber transmission performance. Similarly, after the optical fiber performance test is completed, push the horizontal plate 5 downward until its bottom abuts against the top of the mounting piece 11, and also fix the horizontal plate 5 through the positioning rod 9. At this time, the sealing plate 6 completely shields the outside of the optical fiber interface 2. At this time, the closed cover body formed by the sealing plate 6 and the protective frame 3 can effectively protect the optical fiber interface 2.

[0026] Specifically, as Figure 2 and Figure 4 shown, a reinforcing rod 4 is screwed to the inner surface of the protective frame 3, and a rubber sleeve is sleeved on the open end of the reinforcing rod 4. After connecting the external optical fiber connector to the optical fiber interface 2 on the body 1, the reinforcing rod 4 can be rotated to be screwed with the inner surface of the protective frame 3 until the reinforcing rod 4 abuts against the outer surface of the external optical fiber connector. The frictional force generated by the contact between the reinforcing rod 4 and the external optical fiber connector can effectively limit the loosening of the optical fiber connector, thereby further improving the stability of the portable detector for testing the performance of optical fiber transmission.

[0027] Specifically, asFigure 2 As shown in Figure 3 , the cross-section of the sealing plate 6 is a rectangular structure, and the outer surface wall of the sealing plate 6 is slidably connected to the inner surface wall of the top of the protective frame 3 through the card slot 10, so as to ensure the stability of the vertical movement of the sealing plate 6. The positioning assembly includes a positioning rod 9. The outer surface wall of the positioning rod 9 is screwed with the inner surface wall of the cross plate 5, and the open end of the positioning rod 9 abuts against the outer surface wall of the top seat 7. Rotate the positioning rod 9 to make it screwed with the inner surface wall of the cross plate 5, and the open end of the positioning rod 9 abuts against the outer surface wall of the top seat 7, so as to fix the cross plate 5. A limiting piece 8 is fixedly connected to the top of the top seat 7, so that the rising position of the cross plate 5 can be quickly determined, and the cross plate 5 can be prevented from completely separating from the top seat 7. An installation piece 11 is fixedly connected to the bottom of the top seat 7, and the installation piece 11 is fixedly connected to the top of the fuselage 1 through a locking rod 12, so as to ensure the convenience of disassembly and assembly of the top seat 7.

[0028] Working principle: Move the cross plate 5 upward so that it slides along the outer surface wall of the top seat 7. The cross plate 5 drives the sealing plate 6 until the top seat 7 abuts against the bottom of the limiting piece 8. Rotate the positioning rod 9 to make it screwed with the inner surface wall of the cross plate 5, and the open end of the positioning rod 9 abuts against the outer surface wall of the top seat 7, so as to fix the cross plate 5. At this time, the sealing plate 6 cancels the shielding of the optical fiber interface 2. Connect the external optical fiber connector to the optical fiber interface 2, and then start the test of the optical fiber transmission performance. Similarly, after the optical fiber performance test is completed, push the cross plate 5 downward until its bottom abuts against the top of the installation piece 11, and the cross plate 5 is also fixed by the positioning rod 9. At this time, the sealing plate 6 completely shields the outside of the optical fiber interface 2. At this time, the closed cover body composed of the sealing plate 6 and the protective frame 3 can effectively protect the optical fiber interface 2. After connecting the external optical fiber connector to the optical fiber interface 2 on the fuselage 1, the reinforcing rod 4 can be rotated to make it screwed with the inner surface wall of the protective frame 3 until the reinforcing rod 4 abuts against the outer surface wall of the external optical fiber connector. The frictional force generated by the contact between the reinforcing rod 4 and the external optical fiber connector can effectively limit the loosening of the optical fiber connector, thereby further improving the stability of the portable detector used for the optical fiber transmission performance test.

[0029] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
