[0002] With the development of optoelectronic science, optical fibers have replaced the original cable transmission as the main medium for signal transmission and are widely used. Moreover, with the progress of materials science, the attenuation rates of optical fibers made of different materials and installed in different ways are different. An optical power meter is an instrument for detecting the relative loss of optical power passing through a section of optical fiber.

[0003] According to the utility model patent with the authorization announcement number CN213879825U, a device for detecting signal attenuation of a power communication optical fiber proposed therein relates to the field of signal detection.

A connector is arranged on the side surface of the optical power meter body, and a protection component is fixedly connected to the side surface of the optical power meter body and located at the connector. The protection component adapted to the connector is arranged on the side surface of the existing device to protect the connector.

[0004] However, when the existing optical power meter is carried, it is necessary to carry the machine itself and the power cord separately, which is rather troublesome. Summary of the Invention

A hollow shell is fixedly connected to the back of the optical power meter body. A sliding tube is fixedly connected to the bottom of the hollow shell. A power cord is led out from the back of the optical power meter body. The power cord passes through the sliding tube and extends to the outside of the sliding tube. A rotating shaft is installed in the inner side wall of the hollow shell through a bearing. One end of the rotating shaft located inside the hollow shell is fixedly connected to a wire winding roller, and the wire winding roller is in contact with the power cord. One end of the rotating shaft located outside the hollow shell is fixedly connected to a limiting block. A knob is fixedly connected to the end of the limiting block away from the rotating shaft. A locking mechanism is arranged outside the hollow shell and below the limiting block.

[0008] In addition, the preferred structure is that two wire winding rods are fixedly connected to the outside of the wire winding roller, and the wire winding rods are in contact with the power cord. Through the arrangement of the wire winding rods, it is convenient to wind the power cord on the wire winding roller.

[0009] In addition, a preferred structure is that an elastic clip is fixedly connected to the upper part of the outer side of the hollow shell, and the elastic clip is made of stainless steel. Through the arrangement of the elastic clip, it is convenient to carry the whole device.

[0010] In addition, a preferred structure is that the locking mechanism includes a fixed sleeve fixedly connected to the hollow shell. A locking pin is slidably connected inside the fixed sleeve. The locking pin is inserted into a limiting block, and a spring is arranged inside the fixed sleeve. Through the arrangement of the locking mechanism, in cooperation with the limiting block, it has a locking effect on the rotating shaft.

[0011] In addition, a preferred structure is that one end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner surface of the fixed sleeve. Through the arrangement of the spring, elastic force can act on the locking pin.

[0012] In addition, a preferred structure is that a lever is fixedly connected to the middle section of the pin body of the locking pin. The lever penetrates through the fixed sleeve and is slidably connected to the fixed sleeve. Through the arrangement of the lever, it is convenient to pull the locking pin.

[0013] The beneficial effects of the present utility model are as follows: By providing a hollow shell on the back of the optical power meter body, the power cord of the optical power meter body can pass through the bottom of the hollow shell. In addition, a rotatable rotating shaft is provided on the side wall of the hollow shell, and a wire winding roller is provided on the rotating shaft.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 , a real-time monitoring device for signal attenuation of an optical and electrical composite cable includes an optical power meter body 1. A hollow shell 2 is fixedly connected to the back of the optical power meter body 1. A sliding tube 3 is fixedly connected to the bottom of the hollow shell 2. A power cord 4 is led out from the back of the optical power meter body 1, and the power cord 4 penetrates through the sliding tube 3 and extends to the outside of the sliding tube 3. A rotating shaft 5 is installed inside the side wall of the hollow shell 2 through a bearing. One end of the rotating shaft 5 located inside the hollow shell 2 is fixedly connected to a wire take-up roller 6, and the wire take-up roller 6 is in contact with the power cord 4. Two wire take-up rods 7 are fixedly connected to the outside of the wire take-up roller 6, and the wire take-up rods 7 are in contact with the power cord 4. Through the arrangement of the wire take-up rods 7, it is convenient to wind the power cord 4 on the wire take-up roller 6. One end of the rotating shaft 5 located outside the hollow shell 2 is fixedly connected to a limit block 9, and one end of the limit block 9 away from the rotating shaft 5 is fixedly connected to a knob 10. An elastic clip 11 is fixedly connected to the upper part outside the hollow shell 2, and the elastic clip 11 is made of stainless steel. Through the arrangement of the elastic clip 11, it is convenient for overall carrying.

[0023] Referring to Figures 2-5, a locking mechanism 8 is provided on the outer side of the hollow shell 2 and below the limiting block 9. Through the setting of the locking mechanism 8, in cooperation with the limiting block 9, it has a locking effect on the rotating shaft 5. The locking mechanism 8 includes a fixed sleeve 81 fixedly connected to the hollow shell 2. A locking pin 82 is slidably connected inside the fixed sleeve 81. The locking pin 82 is inserted into the limiting block 9. A spring 83 is arranged inside the fixed sleeve 81. One end of the spring 83 is fixedly connected to the locking pin 82, and the other end of the spring 83 is fixedly connected to the inner surface of the fixed sleeve 81. Through the setting of the spring 83, elastic force can act on the locking pin 82. A lever 84 is fixedly connected to the middle section of the pin body of the locking pin 82. The lever 84 penetrates the fixed sleeve 81 and is slidably connected to the fixed sleeve 81. Through the setting of the lever 84, it is convenient to pull the locking pin 82.

[0024] The specific implementation process of the present utility model is as follows: When in use, first pull down the locking pin 82 through the lever 84, so that the locking pin 82 is separated from the limiting block 9, thereby releasing the restriction on the rotating shaft 5. Then pull the power cord 4 outwards. After connecting the power cord 4 to the power supply, the optical power meter body 1 can be used to monitor the signal of the cable;

[0025] After use, rotate the rotating shaft 5 through the knob 10. The rotating shaft 5 drives the wire winding roller 6 and the wire winding rod 7 to rotate, and then the power cord 4 can be wound onto the wire winding roller 6. Then control the locking pin 82 through the lever 84 to make it re-insert into the limiting block 9, so that the rotating shaft 5 and the wire winding roller 6 can be locked and fixed, thereby preventing the loosening of the power cord 4 after being wound.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
