Description

Technical Field

[0001] This utility model relates to optical line protection equipment technology, specifically an optical line protection device. Background Technology

[0002] Optical communication networks are the foundation of current information communication networks. Due to the advantages of large capacity, low loss, and strong anti-interference capabilities, optical fiber has become the core foundation of the entire information communication network. Generally, because the failure rate of optical fiber lines is much higher than that of communication equipment, multi-route line protection methods are often adopted to meet the requirements of stable communication services. Currently, optical fiber line protection devices are installed inside the casing. When a fault occurs, workers typically open the top cover for repair. Since the cover is installed on the top of the casing with several screws, disassembly and reassembly are cumbersome, thus reducing the efficiency of repair work.

[0003] Chinese Patent CN210274088U discloses an optical fiber line protection device, including a housing and a display screen, cable socket, and control buttons mounted on the side wall of the housing. The top of the housing has an opening, and a first cover plate and a second cover plate are located at the opening. The first cover plate is positioned above the second cover plate. Support columns are located at the four corners of the lower surface of the first cover plate, and the lower ends of the four support columns are fixedly connected to the four corners of the upper surface of the second cover plate. A rolling bearing is embedded in the center of the upper surface of the second cover plate, and a rotating column is rotatably connected to the upper surface of the second cover plate via the rolling bearing. Through holes are opened on the lower surface of the first cover plate at positions corresponding to the rotating columns. This invention allows for quick assembly and disassembly of the first and second cover plates from the housing, facilitating maintenance of the optical fiber line protection device by personnel.

[0004] The existing technical solutions described above have the following drawbacks: when disassembling the first cover plate and the second cover plate from the housing, the bolts need to be unscrewed first and then the rotating column needs to be rotated to unlock the first cover plate and the second cover plate before they can be disassembled from the housing. This makes it difficult to quickly disassemble the housing and facilitate workers' maintenance of the optical line protection equipment inside the housing. In view of the above, technical innovation is carried out on the basis of the existing optical line protection equipment. Utility Model Content

[0005] The purpose of this invention is to provide an optical line protection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical line protection device, comprising:

[0007] A cover plate has a through-hole on its front side, within which a wiring panel is installed. A circuit protection circuit board is connected to the rear side of the wiring panel. Two sets of pull plates are evenly placed on the inner side of the cover plate. Two sets of fixing holes are evenly opened through the front side of each pull plate. Two sets of pins and two sets of second springs are evenly arranged on the outer side of each pull plate. The second springs are located on the outer ring of the pins. A set of mounting holes is opened on both the front and rear sides of each pin. A third spring is installed in each mounting hole. A round-headed pin is installed on the outer side of each third spring. A limit component is installed on the outer side of the circuit protection circuit board.

[0008] Preferably, two sets of slots are evenly provided on the rear side of the cover plate, and a set of storage grooves are provided on both the left and right sides of the cover plate. The storage grooves penetrate the front and rear sides of the cover plate. Two sets of countersunk holes are evenly provided on the inner side of the storage grooves. The countersunk holes are connected to the slots. The pull plate is set in the storage groove. The side of the pin away from the pull plate passes through the countersunk hole and is inserted into the slot. The second spring is fixedly set in the countersunk hole.

[0009] Preferably, a housing is placed on the rear side of the cover plate, the circuit protection circuit board is located inside the housing, and two sets of insert plates are evenly arranged on the front side of the housing, the insert plates being inserted into slots.

[0010] Preferably, two sets of insertion holes are evenly provided on opposite sides of the two sets of insertion plates, and two sets of locking holes are evenly provided on the inner sidewall of the insertion holes. The side of the pin away from the pull plate is inserted into the insertion hole, and the round head part of the round head pin is inserted into the locking hole.

[0011] Preferably, the limiting component includes an L-plate, with connecting rods evenly arranged on the rear side of the L-plate, and a first spring arranged on the rear side of the connecting rods.

[0012] Preferably, the inner sidewall of the outer casing is uniformly provided with grooves, the first spring is fixedly disposed in the groove and is in a fully compressed state, the connecting rod groove is disposed in the groove, the rear side of the circuit protection circuit board is in contact with the rear side of the inner sidewall of the L plate, and the top of the circuit protection circuit board is in contact with the top of the inner sidewall of the L plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a second spring to drive a pin into the insertion hole of the insertion plate, thereby fixing the outer shell to the rear side of the cover plate. After the pin is inserted into the insertion hole of the insertion plate, a third spring drives a round-headed pin into the locking hole of the insertion plate, thereby improving the insertion stability between the pin and the insertion plate, and thus improving the connection stability between the cover plate and the outer shell. When the circuit protection circuit board is inserted into the outer shell, the L-plate limits the outer side of the circuit protection circuit board, ensuring the stability of the circuit protection circuit board within the outer shell, thereby improving the overall reliability of the device.

[0015] When it is necessary to disassemble the outer casing, simply pull the pull plate outward to separate the pin from the plate. Then, using the rebound force of the first spring, the outer casing can be automatically moved backward to separate from the cover plate, thereby achieving the effect of quickly disassembling the outer casing and facilitating workers to inspect and repair the circuit protection circuit board.

[0016] By using bolts to thread through the fixing holes and connect them to the threaded holes on the external frame, the equipment can be fixedly installed on the external frame. At the same time, because the pull plate is fixed by the bolts, it cannot move outward, thus locking the pull plate and improving the overall stability of the equipment during use.

[0023] 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.

[0024] Please see Figures 1-5An optical line protection device includes a cover plate 12. A notch is provided through the front of the cover plate 12, and a wiring panel 1 is fixedly installed within the notch. A line protection circuit board 15 is connected to the rear of the wiring panel 1. Two sets of pull plates 13 are evenly arranged on the inner side of the cover plate 12. Two sets of fixing holes 14 are evenly provided through the front of the pull plates 13. By using bolts to thread through the fixing holes 14 and connect them to threaded holes on an external frame, the device can be fixedly installed on the external frame. Once the device is fixed to the external frame with bolts, the pull plates 13 cannot move outward due to the bolt fixation, thus locking the pull plates 13 and improving the overall stability of the device during use. Two sets of inserts are evenly fixed on the outer side of the pull plates 13. The circuit includes a pin 21 and two sets of second springs 22, with the second springs 22 located on the outer ring of the pin 21. A set of mounting holes is provided on both the front and rear sides of the pin 21, and a third spring 24 is fixedly installed in each mounting hole. A round-headed pin 23 is fixedly installed on the outer side of the third spring 24. A limit assembly is placed on the outer side of the circuit protection circuit board 15. Two sets of slots are evenly provided on the rear side of the cover plate 12. A set of storage grooves is provided on both the left and right sides of the cover plate 12, penetrating the front and rear sides of the cover plate 12. Two sets of countersunk holes are evenly provided on the inner side of the storage grooves, communicating with the slots. A pull plate 13 is slidably disposed within the storage groove. The side of the pin 21 away from the pull plate 13 passes through the countersunk hole and is inserted into the slot. The second spring 22 is fixedly disposed within the countersunk hole. A housing 11 is placed on the rear side of the cover plate 12. The circuit protection circuit board 15 is located inside the housing 11. Two sets of insert plates 2 are evenly fixed on the front side of the housing 11. The insert plates 2 are inserted into slots. Two sets of insertion holes are evenly opened on the opposite sides of the two sets of insert plates 2. Two sets of locking holes are evenly opened on the inner sidewall of the insertion holes. The side of the pin 21 away from the pull plate 13 is inserted into the insertion hole. The round head of the round-headed pin 23 is inserted into the locking hole. The second spring 22 drives the pin 21 to be inserted into the insertion hole of the insert plate 2, thereby fixing the insert plate 2 into the slot of the cover plate 12, and thus fixing the housing 11 to the rear side of the cover plate 12. In this way, the cover plate 12 and the housing 11 cooperate to form a complete housing to protect the circuit protection circuit board 15. When the pin 21 is inserted into the insertion hole of the insert plate 2, the third spring drives the pin 21 to be inserted into the insertion hole of the insert plate 2. 24 drives the round-headed pin 23 to insert into the locking hole of the insert plate 2, thereby improving the insertion stability between the pin 21 and the insert plate 2, and thus improving the connection stability between the cover plate 12 and the outer shell 11. The limiting component includes an L-plate 16, with connecting rods 17 evenly fixed on the rear side of the L-plate 16, and a first spring 18 fixedly fixed on the rear side of the connecting rod 17. Grooves are evenly opened on the rear side of the inner wall of the outer shell 11, and the first spring 18 is fixedly installed in the groove and is in a fully compressed state. The connecting rod 17 is slidably installed in the groove. The rear side of the circuit protection circuit board 15 is in contact with the rear side of the inner wall of the L-plate 16. When the circuit protection circuit board 15 is inserted into the outer shell 11, it will push the L-plate 16 backward, thereby increasing the connecting rod 17 to press the first spring 18 backward.The L-plate 16 limits the rear and top of the circuit protection circuit board 15, ensuring its stability within the housing 11. When the housing 11 needs to be disassembled, simply pull the pull plate 13 outwards to separate the pin 21 from the insert plate 2. Then, the return force of the first spring 18 allows the connecting rod 17 to push the L-plate 16 forward. Since the worker holds the pull plate 13, the cover plate 12 is not pushed forward by the L-plate 16. Therefore, the housing 11 is pushed backward by the L-plate 16, automatically separating from the cover plate 12. This allows for quick disassembly of the housing 11, facilitating the worker's inspection of the circuit protection circuit board 15. The top of the circuit protection circuit board 15 is flush with the top of the inner wall of the L-plate 16.

[0025] Working principle: The second spring 22 drives the pin 21 to insert into the socket of the insert plate 2, thereby fixing the insert plate 2 into the slot of the cover plate 12, and thus fixing the outer shell 11 to the rear side of the cover plate 12. The cover plate 12 and the outer shell 11 cooperate to form a complete housing that protects the circuit protection circuit board 15. When the pin 21 is inserted into the socket of the insert plate 2, the third spring 24 drives the round-headed pin 23 to insert into the locking hole of the insert plate 2, thereby improving the insertion stability between the pin 21 and the insert plate 2, and thus improving the connection stability between the cover plate 12 and the outer shell 11. When the circuit protection circuit board 15 is inserted into the outer shell 11, it pushes the L-plate 16 backward, thereby raising the connecting rod 17 backward. The first spring 18 is squeezed, and the L-plate 16 limits the rear and top of the circuit protection circuit board 15, thereby ensuring the stability of the circuit protection circuit board 15 inside the housing 11. When it is necessary to disassemble the housing 11, simply pull the pull plate 13 outward to separate the pin 21 from the insert plate 2. At this time, the rebound force of the first spring 18 can be used to push the L-plate 16 forward through the connecting rod 17. Since the worker holds the pull plate 13 at this time, the cover plate 12 will not move forward due to the pushing force of the L-plate 16. Therefore, the housing 11 will be pushed backward by the L-plate 16 and automatically separate from the cover plate 12. This achieves the effect of quickly disassembling the housing 11 and facilitating the worker to inspect the circuit protection circuit board 15.

[0026] By using bolts to thread through the fixing hole 14 and connect them to the threaded hole on the external frame, the equipment can be fixedly installed on the external frame. After the equipment is fixed to the external frame by bolts, the pull plate 13 cannot move outward because it is fixed by the bolts, thereby locking the pull plate 13 and improving the overall stability of the equipment during use.
