Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber amplifiers, and particularly relates to a quick disassembly and assembly structure for an optical fiber amplifier. Background Technique

[0002] An optical fiber amplifier refers to a new type of all-optical amplifier used in optical fiber communication lines to amplify signals. It belongs to sensor components. According to its position and function in the optical fiber line, it is generally divided into three types: relay amplification, pre-amplification, and power amplification. Compared with traditional semiconductor laser amplifiers (SOA), OFA does not require complex processes such as optoelectronic conversion, electro-optical conversion, and signal regeneration, and can directly amplify signals in an all-optical manner, with good "transparency".

[0003] In the existing quick disassembly and assembly structure of an optical fiber amplifier, the cost is relatively high when removing the screws of the optical fiber amplifier. For example, a quick disassembly and assembly structure of an optical fiber amplifier shown in the authorized publication number CN217620337U includes a bottom plate, and a placement groove is provided inside the bottom plate. In the above patent, two second electric rods drive two groups of vertical electric screwdrivers to vertically drop to remove the connected screws, and separate the upper and lower covers of the amplifier. Before that, the lower cover and the upper cover need to be fixed respectively. Since the electric screwdriver and the clamping plate are independent of each other, the number of driving sources such as electric push rods in this scheme is relatively large, resulting in a high cost.

[0004] In addition, since the screw needs to be screwed out a certain distance, when the electric screwdriver continuously screws out the screw, the second electric rod needs to lift the electric screwdriver more precisely, which is difficult to control in actual use, resulting in an unsatisfactory disassembly effect.

[0005] Therefore, we propose a quick disassembly and assembly structure for an optical fiber amplifier to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problems in the prior art that the disassembly steps are relatively troublesome and the disassembly effect is unsatisfactory, and to propose a quick disassembly and assembly structure for an optical fiber amplifier.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A quick disassembly and assembly structure for an optical fiber amplifier includes a bottom plate. On both sides of the top surface of the bottom plate, lower clamping plates are slidably arranged. Inside the bottom plate, a lower driving component for driving the two lower clamping plates to move in opposite directions is provided. Above the bottom plate, a top plate is slidably arranged up and down. On both sides of the bottom surface of the top plate, upper clamping plates are slidably arranged. Inside the top plate, an upper driving component for driving the two upper clamping plates to move in opposite directions is provided;

[0009] A plurality of mounting holes are penetratingly formed in the top surface of the top plate. A plurality of mounting plates are detachably and fixedly connected to the top surface of the top plate. Vertical plates are fixedly connected to both sides of the top surface of the mounting plate. A moving plate is slidably arranged up and down between the two vertical plates. An electric screwdriver is fixedly connected through the middle of the moving plate, and the tip of the electric screwdriver passes through the mounting hole and is lower than the bottom surface of the top plate. A spring is fixedly connected between the moving plate and the mounting plate.

[0010] Preferably, a limiting groove is penetratingly formed in the vertical plate, and both sides of the moving plate extend into the limiting groove.

[0011] Preferably, the spring is always in a stretched state during the movement of the moving plate.

[0012] Preferably, a plurality of fixing holes are formed in the top surface of the top plate, and two fixing holes correspond to one mounting hole.

[0013] Preferably, a first sliding groove is formed in the middle of the bottom plate. The lower driving assembly includes a double-headed lead screw rotatably arranged inside the bottom plate, and the two lower clamping plates are respectively threadedly sleeved at both ends of the double-headed lead screw.

[0014] Preferably, the upper clamping plate and the lower clamping plate are perpendicular to each other.

[0015] Preferably, air bags and balls are fixedly connected to the opposite sides of the two lower clamping plates and the opposite sides of the two upper clamping plates.

[0016] Preferably, the balls and air bags on the upper clamping plate are lower than the bottom end of the tip of the electric screwdriver.

[0017] In summary, the technical effects and advantages of the present invention: For the quick disassembly and assembly structure of the fiber optic amplifier, the four sides of the fiber optic amplifier are rectified and fixed by the upper clamping plate and the lower clamping plate. The contact and fit between the tip of the electric screwdriver and the screw on the fiber optic amplifier are realized by the downward pressure of the top plate. The continuous downward pressure on the electric screwdriver during the process of screwing out the screw is realized by the spring. Compared with the existing device, it not only avoids the problem that the electric screwdriver and the upper clamping plate are independent of each other, resulting in a large number of driving sources such as electric push rods, and reduces the cost; but also avoids the problem that it is difficult to control the acting force due to the need for the electric screwdriver to move along with the screw being screwed out for a certain stroke, and improves the disassembly effect.

Specific embodiments

[0023] 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.

[0024] Refer to Figure 1 , Figure 3 , Figure 4 , a quick disassembly and assembly structure for an optical fiber amplifier, including a bottom plate 1. On both sides of the top surface of the bottom plate 1, a lower clamping plate 2 is slidably provided. Inside the bottom plate 1, a lower driving assembly for driving the two lower clamping plates 2 to move in opposite directions is provided. Above the bottom plate 1, a top plate 3 is slidably provided up and down. On both sides of the bottom surface of the top plate 3, an upper clamping plate 4 is slidably provided. Inside the top plate 3, an upper driving assembly 5 for driving the two upper clamping plates 4 to move in opposite directions is provided. The top plate 3 is slid up and down by an electric push rod fixedly installed on one side of the bottom plate 1. The electric push rod is a prior art and will not be described in detail here.

[0025] Refer to Figures 1-3 , a plurality of mounting holes 6 are penetrated and opened on the top surface of the top plate 3, and a plurality of mounting plates 7 are detachably and fixedly connected to the top surface of the top plate 3. On both sides of the top surface of the mounting plate 7, vertical plates 8 are fixedly connected. Between the two vertical plates 8, a moving plate 9 is slidably provided up and down. In the middle of the moving plate 9, an electric screwdriver 10 is fixedly connected through, and the tip of the electric screwdriver 10 passes through the mounting hole 6 and is lower than the bottom surface of the top plate 3. A spring 11 is fixedly connected between the moving plate 9 and the mounting plate 7.

[0026] It should be noted that in order to meet more models of optical fiber amplifiers, the number of mounting holes 6 can be relatively large. When removing a specific model of optical fiber amplifier, the mounting plate 7 can be detachably connected to the corresponding mounting hole 6.

[0027] For the quick disassembly and assembly structure of the fiber optic amplifier, during use, first place the fiber optic amplifier in the middle of the bottom plate 1, then drive two lower clamping plates 2 to move towards the fiber optic amplifier through the lower drive assembly, and align the front and rear sides of the fiber optic amplifier. After completion, press down the top plate 3 and drive two upper clamping plates 4 to move towards the fiber optic amplifier through the upper drive assembly 5, and align the left and right sides of the fiber optic amplifier. After completion, continue to press down the top plate 3 until the tip of the electric screwdriver 10 touches and tightly presses the screw of the fiber optic amplifier. At this time, the spring 11 stretches and applies a downward pressure to the electric screwdriver 10. Turn on the electric screwdriver 10 and unscrew the screw. After the screw is unscrewed, drive the top plate 3 to move upward through the electric push rod, and the top cover and bottom cover of the fiber optic amplifier can be separated.

[0028] A limiting groove 12 is penetrated and opened on the vertical plate 8, and both sides of the moving plate 9 extend into the limiting groove 12. The moving plate 9 is limited in movement through the limiting groove 12 to ensure the vertical movement of the electric screwdriver 10.

[0029] In order to facilitate the electric screwdriver 10 to disassemble the screw, the electric screwdriver 10 needs to always receive a downward pressure, and the spring 11 always remains in a stretched state during the movement of the moving plate 9.

[0030] A plurality of fixing holes 13 are opened on the top surface of the top plate 3, and two fixing holes 13 correspond to one mounting hole 6. The mounting plate 7 is detachably and fixedly connected to the top surface of the top plate 3 through the fixing holes 13 and bolts.

[0031] A first sliding groove 14 is opened in the middle of the bottom plate 1. The lower drive assembly includes a double-headed lead screw 15 rotatably arranged inside the bottom plate 1, and two lower clamping plates 2 are respectively threadedly sleeved at both ends of the double-headed lead screw 15. A lower motor for driving the double-headed lead screw 15 to rotate should also be provided inside the bottom plate 1. The motor is a prior art and will not be elaborated here. By driving the double-headed lead screw 15 to rotate through the lower motor, the reverse movement of the two lower clamping plates 2 is realized.

[0032] The upper drive assembly 5 can have the same principle as the lower drive assembly. By driving the upper lead screw to rotate through the upper motor, the reverse movement of the two upper clamping plates 4 is realized, and no more elaboration will be made here.

[0033] The upper clamping plate 4 and the lower clamping plate 2 are perpendicular to each other. The front and rear sides of the fiber optic amplifier are fixed and aligned by the lower clamping plate 2, and the left and right sides of the fiber optic amplifier are fixed and aligned by the upper clamping plate 4, thereby realizing the positioning of the fiber optic amplifier.

[0034] Since the front and back sides of the fiber optic amplifier are first aligned and fixed by the lower clamping plate 2, at this time, the lower clamping plate 2 may have a large frictional force on the side of the fiber optic amplifier, which hinders the upper clamping plate 4 from being aligned and fixed. To solve the above problems, air bags 16 and balls 17 are fixedly connected to the opposite sides of the two lower clamping plates 2 and the opposite sides of the two upper clamping plates 4. The frictional force on the side of the fiber optic amplifier is reduced by the balls 17, and the fixing after the fiber optic amplifier is aligned and positioned is achieved by the air bags 16. The air bags 16 should be equipped with an air injection device. The air injection device is a prior art and is relatively common in the field of disassembly and fixing, so it will not be elaborated here.

[0035] In order to avoid the problem that the tool bit of the electric screwdriver 10 scratches the fiber optic amplifier due to not being aligned with the screw hole during the alignment and positioning process, the balls 17 and the air bags 16 on the upper clamping plate 4 are both lower than the bottom end of the tool bit of the electric screwdriver 10.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
