[0002] An optical modem, also known as an optical optical signaling modem, is a terminal device used in fiber optic communication networks. Its main function is to convert between optical signals and electrical signals, thereby enabling data transmission in the fiber optic network.

[0003] When repairing optical modems, testing devices are frequently used. While existing testing devices can perform basic testing functions, they generally lack protection for the display screen and buttons. Operators may accidentally press buttons while carrying the device, which can easily activate it and cause error codes during use. Additionally, friction between the display screen and metal objects can cause screen distortion, affecting the operator's ability to view the testing information. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a testing device for repairing optical modems, which has the advantage of protecting the display screen and buttons.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for optical modem repair, comprising a testing device body, a display screen fixedly installed inside the front of the testing device body, a button movably installed below the display screen on the front of the testing device body, a mounting plate fixedly connected to the front of the testing device body and located above the display screen, a protective cover movably sleeved inside the mounting plate, the back of the protective cover movably connected to the front of the testing device body, a first threaded rod threadedly connected to the bottom end of the testing device body, a movable plate movably sleeved on the outer surface of the other end of the first threaded rod, the outer surface of the movable plate movably connected to the inner surface of the testing device body, a connecting rod hinged to the outer surface of the movable plate, and an L-shaped plate hinged to the other end of the connecting rod, the number of L-shaped plates being two, and the outer surfaces of both L-shaped plates movably connected to the inner surface of the testing device body.

[0006] As a preferred embodiment of this utility model, both L-shaped plates are movably fitted with limit rods inside, and the limit rods are fixedly installed inside the detection device body.

[0007] As a preferred embodiment of this utility model, a handle is fixedly connected to the bottom of the front of the protective cover, and the outer surface of the handle is rough.

[0008] As a preferred embodiment of this utility model, the mounting plate has a second threaded rod connected to its internal thread on the front side, and the protective cover has a circular hole located directly above the handle on its front side, the diameter of which is the same as the diameter of the second threaded rod.

[0009] As a preferred technical solution of this utility model, a detection head is fixedly connected to the top of the detection device body. The number of detection heads is two, the two detection heads are the same size, and the two detection heads are symmetrical about the center of the detection device body.

[0010] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the back of the detection device body, a round rod is movably sleeved inside the fixing block, a bracket is fixedly sleeved on the outer surface of the round rod, and the outer side of the bracket is movably connected to the inner side of the fixing block.

[0011] As a preferred technical solution of this utility model, a mounting box located directly below the round rod is fixedly connected to the back of the detection device body. A spring is fixedly connected inside the mounting box, and a pin is fixedly connected to the other end of the spring. The outer surface of the pin is movably connected to the inner surface of the mounting box. A gear is meshed with the outer surface of the top of the pin, and the inner surface of the gear is fixedly sleeved with the outer surface of the round rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a protective cover, a first threaded rod, a movable plate, a connecting rod, and an L-shaped plate, firstly rotates the second threaded rod outward to release the fixing effect on the protective cover. Then, pulling the handle moves the protective cover downward to protect the display screen and buttons. Subsequently, rotating the first threaded rod inward will move the movable plate forward, thereby causing the two connecting rods to rotate and move the two L-shaped plates in opposite directions to insert into the interior of the protective cover to fix it. This achieves the purpose of protecting the display screen and buttons and improves the service life of the detection device body.

[0014] 2. This utility model uses a spring, a pin, and a gear. Pulling the pin downward will compress the spring and separate it from the gear, releasing the fixing effect on the round rod. At this time, rotating the bracket can achieve the function of tilting and supporting the detection device body. Then, releasing the pin will cause the pin to reset and mesh with the gear due to the elasticity of the spring, fixing the round rod. This makes the bracket support more stable and less prone to tipping over due to external forces. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a testing device for optical modem repair, including a testing device body 1. A display screen 2 is fixedly installed inside the front of the testing device body 1. A button 3 located directly below the display screen 2 is movably installed on the front of the testing device body 1. A mounting plate 4 located directly above the display screen 2 is fixedly connected to the front of the testing device body 1. A protective cover 5 is movably sleeved inside the mounting plate 4. The back of the protective cover 5 is movably connected to the front of the testing device body 1. A first threaded rod 6 is threadedly connected to the bottom end of the testing device body 1. A movable plate 7 is movably sleeved on the outer surface of the other end of the first threaded rod 6. The outer surface of the movable plate 7 is movably connected to the inner surface of the testing device body 1. A connecting rod 8 is hinged to the outer surface of the movable plate 7. An L-shaped plate 9 is hinged to the other end of the connecting rod 8. There are two L-shaped plates 9, and the outer surfaces of both L-shaped plates 9 are movably connected to the inner surface of the testing device body 1.

[0024] Rotating the first threaded rod 6 inward will drive the movable plate 7 forward, which in turn causes the two connecting rods 8 to rotate, causing the two L-shaped plates 9 to move in opposite directions and insert into the interior of the protective cover 5 to fix the protective cover 5, thus achieving the purpose of protecting the display screen 2 and the buttons 3.

[0025] Among them, the interior of each of the two L-shaped plates 9 is movably fitted with a limiting rod 10, and the limiting rod 10 is fixedly installed inside the detection device body 1.

[0026] The design of the limit rod 10 serves to limit the movement of the two L-shaped plates 9, ensuring the stability of the horizontal movement of the L-shaped plates 9.

[0027] The bottom of the front of the protective cover 5 is fixedly connected to a handle 11, and the outer surface of the handle 11 is rough.

[0028] The handle 11 is designed to allow operators to slide the protective cover 5 up and down by pulling the handle 11.

[0029] The mounting plate 4 has a second threaded rod 13 connected to its internal thread on the front side, and the protective cover 5 has a round hole 12 located directly above the handle 11 on its front side. The diameter of the round hole 12 is the same as the diameter of the second threaded rod 13.

[0030] With this design, when the protective cover 5 is removed from the display screen 2 and the buttons 3, rotating the second threaded rod 13 downwards can insert it into the round hole 12 to fix the entire protective cover 5, thus making it easier for operators to use the detection device body 1.

[0031] The top of the detection device body 1 is fixedly connected to a detection head 14. There are two detection heads 14, which are the same size and are symmetrical about the center of the detection device body 1.

[0032] The design of the two detection heads 14 serves to connect with the optical modem, thereby enabling the optical modem to be tested and repaired.

[0033] The back of the detection device body 1 is fixedly connected to a fixing block 15, a round rod 16 is movably sleeved inside the fixing block 15, a bracket 17 is fixedly sleeved on the outer surface of the round rod 16, and the outer side of the bracket 17 is movably connected to the inner side of the fixing block 15.

[0034] With this design, the bracket 17 can rotate around the circular rod 16 as the axis, which serves to provide tilt support for the main body 1 of the detection device.

[0035] The back of the detection device body 1 is fixedly connected to a mounting box 18 located directly below the round rod 16. A spring 19 is fixedly connected inside the mounting box 18. A pin 20 is fixedly connected to the other end of the spring 19. The outer surface of the pin 20 is movably connected to the inner surface of the mounting box 18. A gear 21 is meshed with the outer surface of the top of the pin 20. The inner surface of the gear 21 is fixedly sleeved with the outer surface of the round rod 16.

[0036] Pulling the pin 20 downwards will compress the spring 19 and separate it from the gear 21, thereby releasing the fixing effect on the round rod 16.

[0037] Working principle and usage process of this utility model:

[0038] When protecting the display screen 2 and the button 3, firstly, rotate the second threaded rod 13 outward to release the fixing effect on the protective cover 5. Then, pull the handle 11 to move the protective cover 5 downward to protect the display screen 2 and the button 3. Subsequently, rotate the first threaded rod 6 inward, which will drive the movable plate 7 forward. This will cause the two connecting rods 8 to rotate, driving the two L-shaped plates 9 to move in opposite directions and insert into the interior of the protective cover 5 to fix the protective cover 5. This achieves the purpose of protecting the display screen 2 and the button 3 and improves the service life of the detection device body 1.

[0039] When the detection device body 1 is tilted and supported, first pull the pin 20 downwards, which will compress the spring 19 and separate it from the gear 21, thus releasing the fixing effect on the round rod 16. At this time, rotating the bracket 17 can achieve the function of tilting and supporting the detection device body 1. Then, release the pin 20. Due to the elasticity of the spring 19, the pin 20 resets and meshes with the gear 21 to fix the round rod 16, making the bracket 17 support more stable and less likely to tip over due to external forces.
