The adapter 1 is a device used in an optical fiber network, usually used to connect optical fiber network devices with other types of devices. Its function is to perform signal conversion and interface matching in an optical fiber transmission system, thereby realizing connection and communication between different devices. The above is the prior art and will not be described in detail. The side wall of the adapter 1 is fixedly connected with a rectangular block 2, and the outer wall of the rectangular block 2 is slidably connected with a sliding plate 3. The inner wall of the rectangular block 2 is provided with a notch of the same size as the sliding plate 3 to meet the left and right movement of the sliding plate 3. The inner wall of the sliding plate 3 is provided with a limiting mechanism. The inner wall of the rectangular block 2 is provided with a trapezoidal groove 7, and the trapezoidal groove 7 is divided into two notches. When the guide plate 9 is closed, the trapezoidal block 5 is located The first slot, when the guide plate 9 is opened, the trapezoidal block 5 is located in the second slot, and the outer wall of the sliding plate 3 is hinged with the guide plate 9 through the hinge rod 8. The side wall of the guide plate 9 is provided with four sets of sliders to ensure that the guide plate 9 can slide up and down the outer wall of the adapter 1. The top of the guide plate 9 is elastically connected with the adjusting rod 10 through the moving spring 11. When the adjusting rod 10 is pushed upward, the moving spring 11 is in a stretched state. When resetting, the elastic force of the moving spring 11 is used to drive the adjusting rod 10 to reset. The bottom end of the adjusting rod 10 is fixedly connected with a snap-fit ​​plate 12. The arc-shaped opening of the snap-fit ​​plate 12 contacts the optical fiber body, and its contact surface is made of rubber. The top of the guide plate 9 is fixedly connected to one end of the moving spring 11, and the other end of the moving spring 11 is fixedly connected to the inner side wall of the adjusting rod 10.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The outer wall of the clamping plate 12 is fixedly connected with an outer protective sleeve 13, and the inner wall of the outer protective sleeve 13 is slidably connected with an inner protective sleeve 14. The outer protective sleeve 13 is made of metal, and the inner protective sleeve 14 is made of rubber. The friction of the rubber material limits the position of the protective sleeve after extension. The bottom end of the inner protective sleeve 14 is fixedly connected with a clamping block 15. There are two groups of outer protective sleeves 13, and the two groups of outer protective sleeves 13 are in contact with each other. There are two groups of inner protective sleeves 14, and the two groups of inner protective sleeves 14 are plugged into each other. The bottom end of the upper inner protective sleeve 14 is provided with a clamping block 15, and the top of the lower inner protective sleeve 14 is provided with a corresponding notch to ensure that the inner protective sleeves 14 can be plugged into each other.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The limit mechanism includes a paddle 6, which can bring the trapezoidal block 5 to move vertically on the inner wall of the sliding plate 3 by moving the paddle 6, and the paddle 6 is slidably connected to the inner wall of the sliding plate 3. The left end of the paddle 6 is fixedly connected to the trapezoidal block 5, and the right end of the trapezoidal block 5 is an inclined surface. When the trapezoidal block 5 moves to the right in the second notch of the trapezoidal groove 7, the notch will squeeze the inclined surface of the trapezoidal block 5 to make it move upward. The top of the trapezoidal block 5 is elastically connected to the sliding plate 3 through the movable spring 4, and the trapezoidal block 5 moves upward, which will squeeze the movable spring 4. When resetting, the trapezoidal block 5 is reset with the elastic force of the movable spring 4, and the trapezoidal block 5 is slidably connected to the inner wall of the sliding plate 3. The adjusting rod 10 penetrates and is slidably connected to the inner wall of the guide plate 9, and the top of the trapezoidal block 5 is fixedly connected to one end of the movable spring 4, and the other end of the movable spring 4 is fixedly connected to the inner wall of the bottom end of the sliding plate 3, and the trapezoidal block 5 is clamped on the inner wall of the trapezoidal groove 7.

[0035] Reference Figure 1-Figure 3 The locking plate 12 is slidably connected to the inner wall of the guide plate 9. When replacing the connector, the locking plate 12 slides upward without blocking the connector. When the replacement is completed, the locking plate 12 is closed to block the connector and fix the optical fiber body. The outer wall of the sliding plate 3 is hinged to one end of the hinged rod 8, and the other end of the hinged rod 8 is hinged to the side wall of the guide plate 9. The sliding plate 3 moves to the left with one end of the hinged rod 8, and the other end of the hinged rod 8 drives the guide plates 9 to separate from each other. The sliding plate 3 moves to the right with one end of the hinged rod 8, and the other end of the hinged rod 8 drives the guide plates 9 to move closer and close to each other. The guide plate 9 is slidably connected to the outer wall of the adapter 1, and a vertical slot is provided on the outer wall of the adapter 1 to facilitate the up and down sliding of the guide plate 9.

[0036] Working principle: First, when replacing a single connector, use your hand to move the adjusting rod 10 to separate the two groups of adjusting rods 10 from each other and stretch the moving spring 11. At the same time, the adjusting rod 10 drives the single group of snap plates 12 to separate from each other. After pulling out the connector by hand, release the adjusting rod 10. Under the reverse elastic force of the moving spring 11, the adjusting rod 10 drives the adjusting rods 10 to move closer to each other. The adjusting rod 10 will bring the snap plates 12 closer to each other. When replacing multiple connectors, use your hand to move the paddle 6 upward. The paddle 6 drives the trapezoidal block 5 to move upward and squeeze the movable spring 4. When the trapezoidal block 5 moves upward and leaves the first notch of the trapezoidal groove 7, push the sliding plate 3 to the left to move it along the horizontal notch on the rectangular block 2. The sliding plate 3 moves to the left and squeezes the hinge rod 8 to make it deviate. When the hinge rod 8 deviates, it will squeeze the two groups of guide plates 9 to separate them from each other. The two groups of guide plates 9 will move along the adapter 1. After the first notch of the trapezoidal block 5 and the second notch of the trapezoidal groove 7 are overlapped, the hand releases the paddle 6, and the reverse elastic force of the movable spring 4 is used to push the trapezoidal block 5 into the second notch to limit the guide plate 9. The replacement process is completed. When the connector is replaced, only the sliding plate 3 is pushed to the right, and the sliding plate 3 drives the trapezoidal block 5 to move to the right. At the same time, the second notch squeezes the inclined surface of the trapezoidal block 5, so that the trapezoidal block 5 moves upward and compresses the movable spring 4, and the sliding plate 3 drives the hinge rod 8 to move, and the hinge rod 8 pulls the guide plate 9 closer to each other. The two sets of guide plates 9 are closed together. When the trapezoidal block 5 coincides with the first notch of the trapezoidal groove 7, the reverse elastic force of the movable spring 4 is used to insert the trapezoidal block 5 into the first notch of the trapezoidal groove 7 to limit the guide plate 9. The replacement process is completed. When the connector is replaced again, only the above steps need to be repeated.

[0037] When the two groups of guide plates 9 are closed, the two groups of outer protective covers 13 fixedly connected to the outer walls of the locking plates 12 will also be closed together, and the blocks 15 on the two groups of inner protective covers 14 will enter the corresponding slots for insertion. When in use, it is only necessary to drag the inner protective covers 14 outward to extend the protection length of the optical fiber line. When the inner protective covers 14 need to be folded, it is only necessary to push the inner protective covers 14 inward to fold them.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
