Description

Technical Field

[0001] This invention relates to the field of fiber optic testing equipment technology, and more specifically, to a fiber optic testing equipment for network security. Background Technology

[0002] Fiber optic testing equipment for network security utilizes optical fibers to transmit optical signals and converts these signals into electrical signals via photoelectric converters. It features high precision and strong anti-interference capabilities, enabling the measurement of optical fibers and the detection of the operational status of fiber optic lines. Since optical signals are unaffected by electromagnetic interference during transmission, it provides early warning of equipment malfunctions.

[0003] However, the testing requires connecting both ends of the line and detecting any abnormalities in the flow by transmitting signals. The interface of the testing equipment is usually exposed on the outside, and the exposed interface is prone to dust and other small debris. As a result, the line connection is prone to breakage due to the resistance of dust. Furthermore, when the fiber optic connector is connected to the testing equipment, due to the gravity of the fiber optic line and the fact that the fiber itself is relatively flexible and easy to bend, the fiber optic line connector is prone to bending downwards after being fixed at the connection position. This can cause frequent large-angle bending and compression of the line at the connector, resulting in damage to the internal circuitry of the fiber optic line and affecting the flow detection of the closed loop of the fiber optic cable.

The center position of the locking structure is located on the horizontal line of the contact position of the access end.

[0006] As a further improvement of the present invention, the elastic structure is provided with a limiting shaft, a slide rail, an inclined block, and an arc plate. The arc plate is embedded in the upper end of the limiting shaft, and the limiting shaft slides within the slide rail. The inclined block is installed at the lower end of the limiting shaft and is movably engaged with the access end. The slide rail is embedded in the inner side of the housing, and the arc plate is embedded in the inner side of the housing. The arc plate is made of aluminum alloy, which has the characteristics of high toughness and easy bending. The limiting shaft is provided with a circular rod, which limits the movement within the slide rail.

[0007] As a further improvement of the present invention, the force-bearing plate is provided with a movable plate, a flat plate, and a rubber block. The rubber block is attached to the side of the flat plate, the flat plate is embedded in the upper end of the movable plate, and the movable plate is installed on the side of the access end. The movable plate is made of rubber and has a sealed hollow interior, which makes it easy to deform under stress. The flat plate is made of plastic and has a smooth surface.

[0008] As a further improvement of the present invention, the engaging structure includes a corrugated plate, an extension structure, a blocking structure, a movable rod, and a spring rod. The spring rod is fixedly embedded in the side of the extension structure, the corrugated plate is installed on the side of the extension structure, the blocking structure is fixedly embedded in the side of the extension structure, the movable rod slides within the blocking structure, the spring rod is fixedly embedded in the side of the access end, and a spring connection is provided on the left side of the movable rod, while the spring is installed within the blocking structure.

[0009] As a further improvement of the present invention, the blocking structure is provided with a limiting plate, a blocking plate, and a bending block. The bending block is embedded in the inner side of the inclined plate and slides inside the limiting plate. The inclined plate and the blocking plate are engaged with each other. The limiting plate and the blocking plate slide together on the side. The blocking plate is embedded in the side of the extension structure. The limiting plate is installed on the side of the access end. The bending block is made of rubber and has the characteristic of being easily deformable.

[0010] As a further improvement of the present invention, the extended structure includes a connecting block, a threaded rod, a bearing rod, a sponge block, a threaded ring, and a support ring.

The connecting block and the threaded ring are located on the same central axis. The spring rod is embedded in the side of the support ring. There are six connecting blocks, which are evenly distributed in a ring. The threaded rod is connected and fixed to the bearing rod by a connecting rod. Beneficial effects

[0011] 1. In this invention, the fiber optic connector contacts the access end during connection. The connector, through a snap-fit ​​structure, presses against the elastic structure and the force plate, causing the elastic structure and the force plate to open and close to both sides. Subsequently, the fiber optic connector presses against the inclined block and the flat plate. After the flat plate is pressed by the fiber optic, it drives the rubber block to rotate and compress towards the movable plate, thereby providing space for the fiber optic connector to pass through. At the same time, the connector drives the limiting shaft to compress the arc plate, causing the limiting shaft to drive the inclined block to move upward within the slide rail. The inclined block rotates outside the limiting shaft, allowing the connector to fit against the access end through the elastic structure, thereby producing a line connection effect. The elastic structure prevents dust from entering the access device when it is not in use, avoiding dust from affecting the resistance of the fiber optic line.

[0012] 2. In this invention, manually pressing the movable rod causes the bending block to move to the left, thereby disengaging the inclined plate from the blocking plate and pulling the extension structure to move horizontally. Under the elastic force of the spring rod, the extension structure is extended. At the same time, the blocking plate moves horizontally with the extension structure, sliding horizontally outside the limiting plate. After releasing the movable rod, under the elastic force of the spring on the left side of the movable rod, the inclined plate is pressed inward against the blocking plate again, thus achieving the effect of deformation limiting and blocking, and fixing the distance of the extended structure.

[0013] 3. In this invention, rotating the threaded ring drives the threaded rod to rotate, which in turn causes the connecting rod on the threaded rod to rotate, making the bearing rod move outward. This causes the connecting block to expand and contract around the support ring, thereby fixing the line at the fiber optic connector position inside the connecting block to prevent it from bending under gravity. This extends and fixes the line at the fiber optic connector, preventing the fiber optic cable at the connector position from bending and damaging the internal line. Attached Figure Description

Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings: Example

[0024] As attached Figure 1 To be continued Figure 5 As shown: This invention discloses a fiber optic testing device for network security. Its structure includes an exhaust vent 1, a switch 2, an output terminal 3, and a testing mechanism 4. The exhaust vent 1 is embedded in the upper part of the testing mechanism 4. The switch 2 is installed on the side of the testing mechanism 4. The output terminal 3 is embedded in the side of the testing mechanism 4. The testing mechanism 4 includes a connector 41, a detector 42, a housing 43, and an access device 44. The connector 41 is embedded in the side of the detector 42, and the detector 42 is installed inside the housing 43. The access device 44 is embedded in the side of the housing 43 and connected to the internal wiring of the detector 42. The exhaust vent 1 is embedded in the upper part of the housing 43, and the connector 41 is connected to the output terminal 3. A gap is provided on the outer side of the detector 42 for hot air circulation, allowing the access device 44 to connect to the fiber optic line. The fiber optic cable is output through the connector 41 on the side of the detector 42, forming a loop at the output terminal 3, thereby enabling the detection of the line within the detector 42.

[0025] The access device 44 includes a spring structure w1, a snap-fit ​​structure w2, a fixing plate w3, an access end w4, and a force-bearing plate w5. The access end w4 is embedded in the side of the fixing plate w3, and the force-bearing plate w5 is installed on the side of the access end w4. The force-bearing plate w5 is movably engaged with the spring structure w1. The snap-fit ​​structure w2 is embedded in the side of the access end w4. The access end w4 and the fixing plate w3 are embedded in the side of the housing 43. The access end w4 is connected to the internal circuitry of the detector 42. The force-bearing plate w5 is fixed. The center of the snap-fit ​​structure w2 is located on the horizontal line at the contact point of the access end w4. Thus, the optical fiber line is squeezed by the snap-fit ​​structure w2 against the spring structure w1 and the force-bearing plate w5, so that the connector of the optical fiber line fits against the access end w4, thereby producing a line connection effect. The spring structure w1 prevents dust from entering the access device 44 when it is not in use.

[0026] The elastic structure w1 includes a limiting shaft w11, a slide rail w12, an inclined block w13, and an arc-shaped plate w14. The arc-shaped plate w14 is fixed to the upper end of the limiting shaft w11, and the limiting shaft w11 slides within the slide rail w12. The inclined block w13 is installed at the lower end of the limiting shaft w11 and is movably engaged with the access end w4. The slide rail w12 and the arc-shaped plate w14 are both fixed to the inner side of the housing 43. The arc-shaped plate w14 is made of aluminum alloy, which has the characteristics of high toughness and easy bending. The limiting shaft w11 is provided with a circular rod, which limits the movement within the slide rail w12. Then, the fiber optic connector presses against the tilting block w13, which drives the limiting shaft w11 to compress the arc-shaped plate w14. At the same time, the limiting shaft w11 drives the tilting block w13 to move upward within the slide rail w12, and the tilting block w13 rotates outside the limiting shaft w11, so that the connector enters the access end w4 for connection through the elastic structure w1.

[0027] The force-bearing plate w5 includes a movable plate w51, a flat plate w52, and a rubber block w53. The rubber block w53 is attached to the side of the flat plate w52, and the flat plate w52 is embedded in the upper end of the movable plate w51. The movable plate w51 is installed on the side of the access end w4. The movable plate w51 is made of rubber and has a sealed hollow interior, making it easy to deform under stress. The flat plate w52 is made of plastic and has a smooth surface. When the flat plate w52 is squeezed by the optical fiber, it causes the rubber block w53 to rotate and compress towards the movable plate w51, thereby providing space for the optical fiber connector to pass through. The specific usage and function of this embodiment are as follows: In this invention, the access device 44 is connected to the optical fiber line, so that the optical fiber is output through the connector 41 on the side of the detector 42, so that the optical fiber output connection at the outlet 3 forms a loop, and then the line is detected in the detector 42. The optical fiber line connector squeezes the elastic structure w1 and the force plate w5 through the locking structure w2, so that the elastic structure w1 and the force plate w5 open and close to both sides. Then the optical fiber connector squeezes the inclined block w13 and the flat plate w52. After the flat plate w52 is squeezed by the optical fiber, it drives the rubber block w53. The movable plate w51 is rotated and compressed, thus providing space for the fiber optic connector to pass through. At the same time, the connector drives the limiting shaft w11 to compress the arc plate w14, causing the limiting shaft w11 to drive the tilting block w13 to move upward within the slide rail w12. The tilting block w13 is limited to rotate outside the limiting shaft w11, so that the connector fits with the access end w4 through the elastic structure w1, thus producing a line connection effect. The elastic structure w1 prevents dust from entering the access device 44 when it is not in use, avoiding dust from affecting the resistance of the fiber optic route. Example

[0028] As attached Figure 6 To be continued Figure 8 As shown: The engaging structure w2 includes a corrugated plate a1, an extension structure a2, a blocking structure a3, a movable rod a4, and a spring rod a5. The spring rod a5 is embedded in the side of the extension structure a2, the corrugated plate a1 is installed on the side of the extension structure a2, the blocking structure a3 is embedded in the side of the extension structure a2, the movable rod a4 slides within the blocking structure a3, and the spring rod a5 is embedded in the side of the access end w4. The movable rod a4 has a spring connection on its left side, and the spring is installed inside the blocking structure a3, thereby pulling the extension structure a2 to move horizontally, causing the blocking structures a3 to engage with each other. Then, under the elastic force of the spring rod a5, the extension structure a2 is extended, and the optical fiber route is horizontally fixed to prevent bending at the joint.

[0029] The blocking structure a3 includes a limiting plate a31, a blocking plate a32, and a bending block a33. The bending block a33 is embedded inside the inclined plate a34. The w34 slides inside the limiting plate a31. The inclined plate a34 and the blocking plate a32 are engaged with each other. The limiting plate a31 and the blocking plate a32 slide together on their sides. The blocking plate a32 is embedded on the side of the extension structure a2. The limiting plate a31 is installed on the side of the access end w4. The bending block a3... 3 is made of rubber and has the characteristic of easy deformation. Pressing the movable rod a4 causes the bending block a33 to move to the left, thereby causing the inclined plate a34 to disengage from the blocking plate a32. This allows the blocking plate a32 to slide horizontally outside the limiting plate a31 and then follow the extension structure a2. After releasing the movable rod a4, the inclined plate a34 is pressed against the blocking plate a32 again by the elastic force of the spring on the left side of the movable rod a4. This deformation and limiting effect fixes the extension distance.

[0030] The extension structure a2 includes a connecting block a21, a threaded rod a22, a bearing rod a23, a sponge block a24, a threaded ring a25, and a support ring a26. The threaded ring a25 is threadedly engaged with the threaded rod a22. The threaded rod a22 is embedded in the surface of the support ring a26. The bearing rod a23 is embedded in the side of the threaded rod a22 and is installed on the outside of the connecting block a21. The sponge block a24 is attached to the side of the connecting block a21. The connecting block a21 and the threaded ring a25 are located on the same central axis. Above, the spring rod a5 is embedded in the side of the support ring a26. There are six connecting blocks a21, which are evenly distributed in a ring. The threaded rod a22 is connected and fixed to the bearing rod a23 by a connecting rod. Rotating the threaded ring a25 will drive the threaded rod a22 to rotate, and then the connecting rod on the threaded rod a22 will rotate, causing the bearing rod a23 to move outward. This will cause the connecting block a21 to produce a scaling effect around the support ring a26. As a result, the line at the fiber optic connector position is fixed inside the connecting block a21 to prevent it from bending under gravity. The specific usage and function of this embodiment are as follows: In this invention, manually pressing the movable rod a4 causes the bending block a33 to move to the left, thereby disengaging the tilting plate a34 from the blocking plate a32, which in turn pulls the extension structure a2 to translate. Under the elastic force of the spring rod a5, the extension structure a2 is extended, and simultaneously the blocking plate a32 follows the translation of the extension structure a2, causing the blocking plate a32 to slide and translate outside the limiting plate a31. After releasing the movable rod a4, under the elastic force of the spring on the left side of the movable rod a4, the tilting plate a34 is again pressed inwards towards the blocking plate a32 to block the deformation limit. The blocking effect fixes the distance of the extended structure a2, and the rotating threaded ring a25 drives the threaded rod a22 to rotate, which in turn rotates the connecting rod on the threaded rod a22, causing the bearing rod a23 to move outward. This causes the connecting block a21 to produce a scaling effect around the support ring a26, thereby fixing the line at the fiber optic connector position inside the connecting block a21 to prevent it from bending under gravity. This extends and fixes the line at the fiber optic connector, avoiding damage to the internal line caused by the bending of the fiber at the connector position. Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
