Description

Technical Field

[0001] The present invention relates to the technical field of optical transmission equipment protection, and in particular to an optical transmission access protection mechanism. Background Art

[0002] Optical terminal is the terminal equipment for optical signal transmission. It adopts PFM modulation technology to transmit image signals in real time. The transmitter first performs PFM modulation on the analog video signal, and then performs electrical / optical conversion. After the optical signal is transmitted to the receiver, it performs optical / electrical conversion, and then performs PFM demodulation to restore the video signal. Due to the use of PFM modulation technology, its transmission distance can reach 50Km or more. By using wavelength division multiplexing technology, it can also realize two-way transmission of image and data signals on one optical fiber, meeting the actual needs of monitoring projects.

[0003] As a transmission medium, optical fiber patch cords will have necessary bends and turns according to wiring requirements. The bends and turns will directly arrange the optical fiber patch cord into an L shape. The right-angle turn will cause the optical fiber to be excessively bent. Excessive bending will change the transmission path of light, from the transmission mode to the radiation mode, so that part of the light energy penetrates into the cladding or passes through the cladding to become a radiation mode and leak out, thereby causing loss. At the same time, excessive bending will also affect the stress and cause breakage problems.

[0004] At the same time, the optical terminal will generate heat during operation. As the weather temperature increases, the heating rate will also increase. Therefore, heat dissipation ports will be opened on both sides for heat dissipation. The setting of the heat dissipation ports will connect the inside of the optical terminal with the outside world, and a large amount of dust will enter, which may cause short circuit and burnout of components. In order to solve this problem, filter cotton will be pasted on the inside of the heat dissipation port, but the filter cotton originally hinders the air circulation rate, and with the adsorption of dust, the air circulation rate will drop sharply again, and thus the heat dissipation effect will not be effective.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1

[0037] Reference Figure 1 , provides a schematic diagram of the overall structure of an optical transmission access protection mechanism, such as Figure 1-4 , an optical transmission access protection mechanism, comprising:

[0038] Optical transceiver body 100;

[0039] The optical fiber jumper 200 is connected to the port on the back side of the optical terminal body 100 for signal transmission;

[0040] The anti-fracture bending turning part 300 is arranged at the turning point of the fiber jumper 200 wiring, and the anti-fracture of the fiber jumper 200 is achieved by adjusting the bending degree;

[0041] Furthermore, the anti-breakage bending turning portion 300 includes an outer ring component 301 and an inner ring component 302 disposed inside the outer ring component 301 .

[0042] Furthermore, the outer ring assembly 301 includes a fixed disk 301a and an outer ring 301b. The fixed disk 301a and the outer ring 301b are fixedly connected by a plurality of connecting columns 301c distributed in a ring array. The space between two adjacent connecting columns 301c serves as a threading channel 301d for the optical fiber jumper 200 to pass through in and out. This structure has good heat dissipation between the fixed disk 301a and the outer ring 301b of the optical fiber jumper 200.

[0043] Specifically, the back side of the fixing plate 301a is pasted with double-sided tape. When wiring, one end of the optical fiber jumper 200 is passed through one of the threading channels 301d, and then passed out from the other threading channel 301d. The optical fiber jumper 200 is arranged according to the original line and fixed to the wall through C-type line clips section by section. When encountering a turn, the double-sided tape on the back side of the fixing plate 301a is torn off and pasted at the turn.

[0044] Furthermore, the inner ring assembly 302 includes a rotating disk 302a, a semi-annular groove 302b is opened on the outer side of the rotating disk 302a, a long arc plate 302c is arranged in the semi-annular groove 302b, and a short arc plate 302d is arranged on one side of the long arc plate 302c in the semi-annular groove 302b, and the long arc plate 302c and the short arc plate 302d rotate relative to each other through the adjusting member 302e.

[0045] Specifically, the short arc plate 302d corresponds to the inlet position and has a "7" structure. When rotated 90°, the upper end surface of the short arc plate 302d is horizontal, which is used to hold up the horizontally arranged optical fiber jumper 200. The end of the long arc plate 302c is located at the outlet position, which is used to reduce the bending angle of the optical fiber jumper 200 through the arc structure to avoid the problem of breakage and affecting the transmission rate due to excessive folding;

[0046] Furthermore, the adjusting member 302e includes a large gear 302e-1 and a small gear 302e-2. The rotating shafts of the large gear 302e-1 and the small gear 302e-2 are both rotatably connected to the inner side of the semi-annular groove 302b, and the large gear 302e-1 and the small gear 302e-2 are meshingly connected.

[0047] Specifically, the number of teeth of the small gear 302e-2 is less than that of the large gear 302e-1. When the small gear 302e-2 rotates 90°, the large gear 302e-1 can only rotate 30°. One end of the long arc plate 302c and the short arc plate 302d are respectively fixed on the rotating shafts of the large gear 302e-1 and the small gear 302e-2, wherein one end of the rotating shaft of the small gear 302e-2 passes through the rotating disk 302a and is fixed with a knob 302e-3. When adjusting, the knob 302e-3 is turned by hand, and the rotation angle is 90°. When the knob 302e-3 is turned 90°, the small gear 302e-2 will be driven to rotate 90° synchronously. Since the short arc plate 302d is fixed on the rotating shaft of the small gear 302e-2, The short arc plate 302d rotates synchronously by 90°. After rotating by 90°, the upper end of the short arc plate 302d is horizontal, which lifts the fiber optic patch cord 200 entering the threading channel 301d, so that the fiber optic patch cord 200 at the entrance is restricted by the short arc plate 302d and the connecting column 301c, and the long arc plate 302d rotates in the opposite direction by 30° under the action of the small gear 302e-2, so that the long arc plate 302d rotates slightly outward to open, thereby increasing the curvature. The long arc plate 302d with increased curvature is used to bend the fiber optic patch cord 200 in an arc to achieve a steering effect. The larger the outer diameter of the arc, the smaller the curvature of the fiber optic patch cord 200 along its arc. Therefore, the stress damage to the fiber optic patch cord 200 can be reduced, and there will be no problem of excessive bending and breakage.

[0048] Specifically, the other end of the rotating shaft of the pinion 302e-2 is sleeved and fixed with a ratchet 302e-4, and a spring sheet 302e-5 is fixed to the outer side of the rotating disk 302a. The other end of the spring sheet 302e-5 is placed on the outer teeth of the ratchet 302e-4. The ratchet 302e-4 rotates with the rotation of the pinion 302e-2. When rotating clockwise, the spring sheet 302e-5 will tilt upward along with the inclined surface of the outer teeth of the ratchet 302e-4. When the inclined surface of the outer teeth is no longer in contact with the ratchet 302e-4, the spring sheet 302e-5 will reset. For reversal, the spring sheet 302e-5 needs to be manually bent up, otherwise the outer teeth of the ratchet 302e-4 will abut against the end of the spring sheet 302e-5. At this time, the spring sheet 302e-5 will not tilt, so it can prevent reversal.

[0049] The outer ring assembly 301 and the inner ring assembly 302 are movably connected by a stretching rotating assembly, which includes a toothed ring a1 fixed to the inner side of the fixed disk 301a, a guide rod a2 fixed to the inner axis of the fixed disk 301a, and an inner groove a3 opened at the axis of the rotating disk 302a. A toothed ring a4 is fixed to the inner side of the inner groove a3, and a movable disk a5 is fixed to the axis of the inner groove a3. The movable disk a5 is fixed in the inner groove a3 by a connecting rod, and a through hole is opened at the axis of the movable disk a5 for the guide rod a2 to pass through. A spring a6 is sleeved on the outer side of the guide rod a2 to pull the rotating disk outward. When the rotating disk 302a is moved, the movable disk a5 in the inner groove a3 will be displaced along the axial direction of the guide rod a2, and the spring a6 will be compressed during the displacement. At this time, the gear ring a4 in the inner groove a3 will be separated from the gear ring a1, so the rotating disk 302a can be rotated. According to the position of the optical fiber jumper 200 entering the threading channel 301d and moving out of the threading channel 301d, the rotating disk 302a is rotated until the short arc plate 302d and the long arc plate 302c are respectively moved to the inlet and outlet positions of the optical fiber jumper 200. This structure can be adjusted from the bottom according to the threading inlet and outlet positions, which reduces the difficulty of operation and improves the wiring efficiency.

[0050] Operation process: When wiring, pass one end of the optical fiber jumper 200 through one of the threading channels 301d, and then pass it out from the other threading channel 301d. Arrange the optical fiber jumper 200 according to the original line and fix it to the wall section by section through C-type line clips. When encountering a turn, tear off the double-sided tape on the back of the fixing plate 301a and stick it on the turn;

[0051] During adjustment, the knob 302e-3 is turned by hand, and the turning angle is 90°. When the knob 302e-3 is turned 90°, the pinion 302e-2 will be driven to turn 90° synchronously. Since the short arc plate 302d is fixed on the rotating shaft of the pinion 302e-2, it will turn 90° synchronously. After turning 90°, the upper end of the short arc plate 302d is horizontal, and the optical fiber jumper 200 entering the threading channel 301d is lifted, so that the optical fiber jumper 200 at the entrance passes through the short arc plate 302d and the connecting The connecting column 301c is limited, and the long arc plate 302d rotates in the opposite direction by 30° under the action of the small gear 302e-2, so that the long arc plate 302d rotates slightly outward to open, thereby increasing the curvature. The long arc plate 302d with increased curvature is used to bend the optical fiber jumper 200 in an arc to achieve a turning effect. The larger the outer diameter of the arc, the smaller the curvature of the optical fiber jumper 200 along its arc. Therefore, the stress damage to the optical fiber jumper 200 can be reduced, and the problem of excessive bending and breakage will not occur.

[0052] Example 2

[0053] Reference Figure 5-7 This embodiment is different from the first embodiment in that the optical transmission access protection mechanism of this embodiment further includes:

[0054] The dustproof and ventilating parts 400 are installed on both sides of the optical terminal body 100 to achieve ventilation and dustproof.

[0055] The dustproof and ventilating part 400 includes a housing component 401 and an air supply and dustproof component 402 installed inside the housing component.

[0056] Furthermore, the housing assembly 401 includes a wind collecting cover 401a and an air duct 401b disposed on one side of the wind collecting cover 401a, and a dust filter plate 401c is installed on the rear side of the air duct 401b.

[0057] Furthermore, the air supply and dust prevention component 402 includes a motor frame 402a installed inside the air duct 401b, a motor 402b is installed on one side of the motor frame 402a, and a fan blade 402c is arranged on the other side of the motor frame 402a, and a transmission shaft of the motor 402b passes through the motor frame 402a and is fixedly connected to the fan blade 402c.

[0058] Specifically, the motor frame 402a is composed of a mounting plate and support rods equidistantly arranged outside the mounting plate. The wind hood 401a, the motor frame 402a and the air duct 401b are integrally formed by injection molding, and have high stability. The motor 402b is connected to an external power supply to run, thereby driving the fan blades 402c to rotate, introducing external airflow, and blowing the airflow through the heat dissipation port on one side of the optical terminal body 100, and then entering the interior of the optical terminal body 100, driving the heat source generated by the work inside, and finally discharged from the heat dissipation port on the other side, which can achieve the effect of rapid cooling;

[0059] Specifically, a gear ring 1 402d is sleeved and fixed on the transmission shaft of the motor 402b, a gear ring 2 402e is arranged on one side of the gear ring 1 402d, the central axis of the gear ring 2 402e is rotatably connected to the housing assembly 401, a rotating rod 402f is arranged on the outer side of the gear ring 1 402d and the gear ring 2 402e, the rotating rod 402f is rotatably connected to the inner wall of the air duct 401b through a bearing seat 402g, and driven gears 402h are fixed at both ends of the rotating rod 402f, which are respectively meshed and connected with the gear ring 1 402d and the gear ring 2 402e, and a cleaning bristle 402i that fits the housing assembly 401 is arranged on the inner side of the gear ring 2 402e. When the motor 402b rotates, it will drive the ring gear 1 402d to rotate, and the ring gear 1 402d will drive one of the driven gears 402h to rotate. After the driven gear 402h rotates, the rotating rod 402f will rotate synchronously. At the same time, the other driven gear 402h will drive the ring gear 2 402e to rotate. After the ring gear 2 402e rotates, the cleaning hair 402i on its inner side will quickly push out the dust adsorbed in the filter holes of the dust filter plate 401c, thereby playing a dust-proof role, preventing dust from entering the interior of the optical terminal body 100 from the heat dissipation port to cause safety hazards, and solving the problem of traditional methods of affecting airflow by sticking filter cotton on the heat dissipation port.

[0060] The rest of the structure is the same as that of Example 1.

[0061] Operation process: The motor 402b is connected to an external power source to run, thereby driving the fan blade 402c to rotate, introducing external airflow, and blowing the airflow into the optical terminal body 100 through the heat dissipation port on one side, and then entering the optical terminal body 100, driving the heat source generated by the work inside, and finally discharged from the heat dissipation port on the other side, so as to achieve the effect of rapid cooling;

[0062] When the motor 402b rotates, it will drive the ring gear 1 402d to rotate, and the ring gear 1 402d will drive one of the driven gears 402h to rotate. After the driven gear 402h rotates, the rotating rod 402f will rotate synchronously. At the same time, the other driven gear 402h will drive the ring gear 2 402e to rotate. After the ring gear 2 402e rotates, the cleaning hair 402i on its inside will quickly push out the dust adsorbed in the filter holes of the dust filter plate 401c, thereby playing a dust-proof role, preventing dust from entering the interior of the optical terminal body 100 from the heat dissipation port to cause safety hazards, and solving the problem of traditional methods of affecting airflow by sticking filter cotton on the heat dissipation port.

[0063] Example 3

[0064] Reference Figure 8 This embodiment is different from the above embodiments in that the dustproof ventilation part 400 also includes a quick-release component 403, which is respectively arranged at both ends of the wind collecting cover 401a, and is used to quickly install the wind collecting cover 401a on the heat dissipation side of the optical terminal body 100.

[0065] Specifically, the quick-release assembly 403 includes two fixing seats 403a that are symmetrically arranged in an upper and lower manner. The two fixing seats 403a are fixed to the ends of the wind condenser 401a, and displacement rods 403b are inserted relatively on the two fixing seats 403a. The far ends of the two displacement rods 403b are fixed with clamping blocks 403c, and the proximal ends of the two displacement rods 403b are fixed with threaded rods 403d. The two threaded rods 403d are threadedly connected by threaded sleeves 403e. During installation, the wind condenser 401a is attached to the outer side of the optical terminal body 100 and corresponds to the position of the heat dissipation port. At this time, ensure that the two clamping blocks 403c are respectively located on the optical terminal body 100, further rotate the threaded sleeve 403e, the threaded sleeve 403e is provided with positive / negative internal threads at both ends with the center line as the boundary, and the screw teeth of the two threaded rods 403d are respectively adapted to the positive / negative internal threads, so through the thread characteristics, the two threaded rods 403d will be screwed into the threaded sleeve 403e after rotation, and the threaded rods 403d will drive the displacement rod 403d to move synchronously and relatively during the screwing process. Since the displacement rod 403d is a hexagonal prism structure, its rotation can be restricted, and it can only be forced to move up and down, so that the two clamping blocks 403c are clamped on the upper and lower sides of the optical terminal body 100 and form a clamping force to complete the installation;

[0066] During disassembly, the threaded sleeve 403e is reversed so that the screwed-in threaded rod 403d is screwed out from the inside, so that the two clamping blocks 403c are moved away from each other, and the clamping of the optical terminal body 100 is released to complete the disassembly. This structure has the advantage of fast disassembly and assembly, and can meet the use of optical terminal bodies 100 of different thicknesses. It has strong practicality, and the disassembly and assembly are simple and fast, which reduces the disassembly and assembly time.

[0067] The rest of the structure is the same as that of Example 2.
