[0016] S1: bolt connection: first, insert the connecting frame into the equipment to be connected and connect it with the equipment by bolts;

[0017] S2: push insertion: then insert the main body into the inside of the connecting frame and connect it with the optical fiber equipment through the connecting frame;

[0018] S3: sliding connection: when the main body is inserted into the inside of the connecting frame, continue to push the main body to slide in the inside of the connecting frame, when the main body is completely slid into the inside of the connecting frame, the main body and the connecting frame form a complete connection structure at this time.

[0019] The present application has the following beneficial effects:

[0020] 1. The application, when the main body is inserted into the inside of the connecting frame, the inner wall of the connecting frame will extrude the triangular elastic plate, and then continue to push the main body to drive the triangular elastic plate to slide inside the connecting frame, when the inner wall of the connecting frame extrudes the triangular elastic plate, the triangular elastic plate is extruded, and one end of the triangular elastic plate close to the annular groove will slide inside the annular groove, when the triangular elastic plate slides obliquely, the arc-shaped elastic plate will be driven by the sliding frame to slide on the surface of the triangular elastic plate, and at the same time, when the triangular elastic plate slides obliquely, the sliding of the triangular elastic plate pushes the bottom of the arc-shaped elastic plate, so that the arc-shaped elastic plate pushes the oval rubber ring to expand outward, and then when the main body continues to move, the triangular elastic plate will slide into the square groove, since the four sides of the main body are provided with triangular elastic plates, when the triangular elastic plate is clamped in the square groove, the main body and the connecting frame can form close contact and interaction force in multiple directions, and at the same time, when the oval rubber ring expands outward, it also extrudes the inner wall of the connecting frame and forms a larger contact area and friction force on the inner wall of the connecting frame, so as to provide more stable connection, reduce the influence of external vibration, pulling and other factors on the connection, and reduce the possibility of loose connection.

[0021] 2. The application, when the triangular elastic plate is extruded by the inner wall of the connecting frame and slides inside the annular groove, the sliding of the triangular elastic plate will drive one end of the arc-shaped elastic plate to slide towards the triangular elastic plate through the sliding frame, and when the sliding frame slides, it will pull one side of the oval rubber ring through the square groove, then when the triangular elastic plate slides, the sliding of the triangular elastic plate will push the bottom of the arc-shaped elastic plate, so that the oval rubber ring contacts the inner wall of the connecting frame, at this time, the oval rubber ring after being pulled contacts the inner wall of the connecting frame under the pulling of the arc-shaped elastic plate and the pushing of the triangular elastic plate, the oval rubber ring after being pulled can fill the gap between the connecting frame and the main body, so as to reduce the entry of external dust and water vapor at the connection, and improve the protection efficiency of the connection.

[0022] 3. According to the present invention, when the triangular elastic plate slides into the inside of the square groove, the corner of the triangular elastic plate will squeeze the inclined plate 1, and the inclined plate 1 will drive the moving frame to slide in the direction of the main body after being squeezed. When the moving frame slides, it will squeeze the hollow ball through the inclined plate 2. After being squeezed, the hollow ball will slide inside the conical groove and contact the surface of the elliptical rubber ring. At the same time, the corner of the triangular elastic plate pushes the inclined plate 1 so that the inclined plate 1 drives the moving frame to slide. The sliding of the moving frame will also be subjected to the pulling force of the spring 1 on its side wall to react and squeeze the triangular elastic plate. At this time, the situation of excessive plugging and unplugging force and difficulty in plugging and unplugging caused by the force of the triangular elastic plate on the inner wall of the connecting frame and the squeezing and friction force of the elliptical rubber ring on the inner wall of the connecting frame can be reduced, the situation of possible damage to the main body or the connecting frame due to difficulty in plugging and unplugging can be reduced, and the operation time can be reduced while improving the connection efficiency.

[0023] 4. In the present invention, when the movement of the moving frame squeezes the hollow ball through the inclined plate 2, the hollow ball will slide inside the conical groove and squeeze the elliptical rubber ring after being squeezed, and then when the moving frame continues to slide, the sliding of the inclined plate 2 will make the flexible bag be above the hollow ball. Originally, when the hollow ball was squeezed by the inclined plate 2, the hollow ball would produce a certain contraction deformation. When the flexible bag slides to the top of the hollow ball, the hollow ball will recover under the action of the elastic force of the return spring inside it. When the hollow ball recovers, the side wall of the flexible bag will cover several air outlets on the hollow ball. Then, when the return spring continues to recover, a certain negative pressure area will be formed inside it. Under the slow recovery of the hollow ball, the negative pressure inside it will absorb the elliptical rubber ring through the air outlet. At the same time, when the hollow ball squeezes the elliptical rubber ring, it can fill the tiny gap between the elliptical rubber ring and the connecting frame and the main body. In addition, the hollow When the ball recovers, the adsorption of the elliptical rubber ring through the air outlet can further enhance the sealing effect. At the same time, the adsorption force of the elliptical rubber ring can further drive the elliptical rubber ring to contact the inside of the connection frame, further reducing the impact of external dust entering the adapter on the erosion and damage of internal components and connection parts, which is beneficial to maintaining the long-term stability of the connection performance and extending the service life of the equipment. At the same time, since the hollow ball itself has a certain elasticity, combined with the elastic force of the reset spring, the hollow ball can absorb part of the external impact force during the extrusion and deformation process, and form a buffer layer inside the device. The elastic deformation of the hollow ball and the buffering effect of the gas inside can effectively reduce the propagation of vibration in the connection part. This buffering effect can further reduce the damage to the connection structure caused by the impact force, thereby enhancing the integrity and reliability of the protective connection.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] When the triangular elastic plate 201 slides to the inside of the square slot 303, the corners on the triangular elastic plate 201 will extrude the inclined plate one 402, after the inclined plate one 402 is extruded, it will drive the moving frame 401 to slide to the direction of the main body 1, when the moving frame 401 slides, it will extrude the hollow ball 501 through the inclined plate two 404, after the hollow ball 501 is extruded, it will slide in the inside of the tapered slot 302 and contact with the surface of the elliptical rubber ring 204, at the same time, when the corners of the triangular elastic plate 201 push the inclined plate one 402 to make the inclined plate one 402 drive the moving frame 401 to slide, the sliding of the moving frame 401 will also be extruded by the pulling force of the spring one on the side wall of the moving frame 401 to the triangular elastic plate 201, at this time, it can reduce the situation that the plug-in and plug-out force is too large and it is difficult to plug-in and plug-out due to the extrusion and friction force of the elliptical rubber ring 204 to the inner wall of the connecting frame 301 and the action force of the triangular elastic plate 201 to the inner wall of the connecting frame 301, reduce the situation that the main body 1 or the connecting frame 301 may be damaged due to the difficulty of plug-in and plug-out, reduce the operation time and improve the connection efficiency.

[0055] When the movement of the moving frame 401 is extruded by the inclined plate two 404 to the hollow ball 501, the hollow ball 501 is extruded and slides in the inside of the conical groove 302 and extrudes the elliptical rubber ring 204, and then when the moving frame 401 continues to slide, the sliding of the inclined plate two 404 makes the flexible bag 403 above the hollow ball 501, and the hollow ball 501 will produce a certain shrinkage deformation when it is extruded by the inclined plate two 404, when the flexible bag 403 slides to the top of the hollow ball 501, the hollow ball 501 will be restored under the action of the restoring spring 502 inside it, and the side wall of the flexible bag 403 will cover the several air outlets 503 on the hollow ball 501 when the hollow ball 501 is restored, and then when the restoring spring 502 continues to restore, a certain negative pressure area will be formed inside it, and the negative pressure inside the hollow ball 501 will be adsorbed to the elliptical rubber ring 204 through the air outlet 503, at the same time, the hollow ball 501 can fill the small gap between the elliptical rubber ring 204 and the connecting frame 301 and the main body 1 when extruding the elliptical rubber ring 204, and the adsorption of the elliptical rubber ring 204 through the air outlet 503 when the hollow ball 501 restores can further enhance the sealing effect, and the adsorption force of the elliptical rubber ring 204 can further drive the inside of the elliptical rubber ring 204 and the connecting frame 301 to contact, further reducing the erosion and damage of external dust to the internal elements and connecting parts, which is beneficial to maintain the long-term stability of the connection performance and prolong the service life of the equipment, and at the same time, due to the elasticity of the hollow ball 501 itself, in combination with the elastic force of the restoring spring 502, the hollow ball 502 can also absorb part of the impact force from the outside during the extrusion and deformation process, and form a buffer layer inside the device, and the elastic deformation of the hollow ball 502 and the buffer effect of the gas inside can effectively weaken the propagation of vibration in the connecting part, which can further reduce the damage to the connecting structure caused by the impact force, thereby enhancing the protection of the integrity and reliability of the connection.

[0056] When the flexible bag 403 moves to the top of the hollow ball 501, the inclined plate two 404 and the inclined plate one 402 will extrude the sealing frame 305, and at this time the sealing frame 305 will seal the side wall of the inclined plate one 402 and the inclined plate two 404, so that a sealed area is formed around the hollow ball 501.
