DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] like Figures 1 to 16As shown, the automatic docking device for optical fiber adapters of the present invention comprises a first adapter end 1, a second adapter end 2 and a docking assembly 3. The first adapter end 1 and the second adapter end 2 are connected through the docking assembly 3 installed on the second adapter end 2. During docking, a driving member 4 with a triangular cross section pushes the symmetrically arranged pressing member 5 in the opposite direction, so that the pressing member 5 pushes the symmetrically arranged movable member 6 to rotate toward one end of the tension spring 7, and the movable member 6 is kept to compress the tension spring 7. The movable member 6 drives the retaining member 9 originally at a higher position of the guide slope 8 to move to the connection between the blocking surface 10 and the guide slope 8 at a lower position, so that the arc body 11 contacts the edge surface of the movable member 6, so that the distance between the locking tooth 12 and the center line of the fixed end 14 is smaller than the inner diameter of the first annular portion 13. When the retaining member 9 is placed in the docking chamber 15, the distance between the locking tooth 12 and the center line of the fixed end 14 is greater than the inner diameter of the first annular portion 13, so that the retaining member 9 is limited in the docking chamber 15 by the first annular portion 13, so that the first adapter end 1 and the second adapter end 2 will not be easily separated.

[0041] The first adapter end 1 is composed of a first connecting sleeve 16 and a first pair of joints 17. The first pair of joints 17 is hollowed out to form a docking chamber 15. The first annular portion 13 is provided in the docking chamber 15. A second annular portion 18 is provided outside the first pair of joints 17. The second annular portion 18 is used to block the sealing sleeve 19. After the docking is completed, the sealing sleeve 19 is set on the first pair of joints 17 and the second pair of joints 20 to prevent dust and impurities from entering the docking assembly 3. The inner diameter of the sealing sleeve 19 in the natural state is smaller than the outer diameter of the first pair of joints 17 and the second pair of joints 20. When the sealing sleeve 19 is installed, the sealing sleeve 19 is deformed by force to improve the sealing effect.

[0042] The second adapter end 2 is mated with the first adapter end 1, and the second adapter end 2 is composed of a second connection sleeve 21 and a second pair of joints 20. An extension section 22 is provided on the second pair of joints 20, and the extension section 22 is provided with a fixed end 14. The fixed end 14 is provided with a plurality of one-way recesses 23. A blocking surface 10 and a guide slope 8 are provided in the one-way recess 23, and the blocking surface 10 is arranged perpendicular to the guide slope 8. When the symmetrical pressing members 5 are separated by force, the retaining member 9 is at one end of the guide slope 8, and when the symmetrically arranged pressing members 5 are pushed by the tension spring 7, the retaining member 9 is at the connection between the blocking surface 10 and the guide slope 8.

[0043] The extension section 24 is located on one side of the fixed end 14 , and a blocking end 25 is provided on the other side of the fixed end 14 . The blocking end 25 is used to limit the position of the docking assembly 3 so that it remains in the docking chamber 15 .

[0044] A limit block 26 is provided on the extension section 22, the movable member 6 and one end of the movable member 6 form a compression area 27, and the other end forms an expansion area 28, the tension spring 7 is at one end of the compression area 27, the expansion area 28 is at one end of the pressing member 5, and the limit block 26 is in the compression area 27. The limit block 26 can limit the distance that the compression area 27 is compressed to prevent the tension spring 7 from being excessively compressed.

[0045] The first connection sleeve 16, the second connection sleeve 21, the extension section 22 and the blocking end 25 are all hollowed out, and the optical fiber is arranged therein. After the optical fiber is welded by professional welding equipment, the first adapter end 1 and the second adapter end 2 can protect the connection. At the same time, the first adapter end 1 and the second adapter end 2 can also be used to protect the docking optical fiber heads to avoid disconnection of the contact heads and ensure the stability of the optical fiber connection.

[0046] The docking assembly 3 is arranged on the fixed end 14, and the docking assembly 3 is composed of four movable parts 6 arranged symmetrically in pairs, and the movable parts 6 are arranged on both sides of the fixed end 14, and the movable parts 6 are installed on the fixed end 14 through the first bolts 29. Two movable parts 6 are respectively arranged on both sides of the fixed end 14, and the movable parts 6 are symmetrically arranged on both sides of the fixed end 14 in left-right and up-down directions.

[0047] The movable member 6 is provided with an arc-shaped opening 30 , which is matched and installed with the blocking end 25 and the extension section 24 .

[0048] A retaining member 9 is provided in the one-way recess 23, and both ends of the retaining member 9 are mounted on the movable members 6 on both sides of the fixed end 14. The movable members 6 on both sides of the fixed end 14 are connected to one end of the movable members 6 through a tension spring 7, and a symmetrically arranged pressing member 5 is provided at the other end.

[0049] The symmetrically arranged pressing member 5 is pushed backwards, the tension spring 7 is kept compressed, and the retaining member 9 arranged in the one-way recess 23 is moved closer to the middle of the fixed end 14, so that the distance from the locking tooth 12 to the center line of the fixed end 14 is smaller than the inner diameter of the first annular portion 13, and the docking assembly 3 can be placed in the docking chamber 15. When the pushing force of the pressing member 5 is canceled, the movable member 6 is pushed under the elastic force of the tension spring 7, the cylinder 31 is guided by the guiding inclined surface 8, and the moving body 32 is guided by the moving groove 33. The cooperation between the movable member 6 and the one-way recess 23 causes the retaining member 9 to be pushed outwards under the force, and is installed in the docking chamber 15 to complete the docking of the first adapter end 1 and the second adapter end 2.

[0050] The retaining member 9 is composed of a cylindrical body 31, a connecting body 34 and an arc-shaped body 11. The two ends of the cylindrical body 31 are provided with moving bodies 32. The connecting body 34 connects the arc-shaped body 11 and the cylindrical body 31. The arc-shaped body 11 is provided with symmetrically arranged locking teeth 12, which face two different directions, so that the first adapter end 1 and the second adapter end 2 cannot rotate after the docking is completed.

[0051] The movable member 6 is provided with a moving groove 33 that matches the moving body 32. The height of the moving body 32 is smaller than that of the moving groove 33. The cross section of the moving body 32 is square, and the cross section of the moving groove 33 is rectangular. Of course, a spring 35 can be provided between the inner wall of the moving groove 33 facing the outside and the moving body 32, so that the spring 35 pushes the moving body 32, so that the cylinder 31 can be assisted by the external force of the spring 35 to move from the higher end of the guide slope 8 to the lower end.

[0052] The movable part 6 is also provided with an arc groove 36, and the fixed end 14 is provided with a first threaded hole 37 that matches the first bolt 29. The first bolt 29 passes through the arc groove 36 and is connected to the first threaded hole 37. A gasket 38 is provided on the first bolt 29, and the first bolt 29 passes through the gasket 38 and the arc groove 36 is placed in the first threaded hole 37.

[0053] The movable member 6 is provided with a fixing column 39 , and the fixing column 39 is provided with a limiting pin 40 . The limiting pin 40 can limit the two ends of the tension spring 7 from being separated from the fixing column 39 .

[0054] The pressing member 5 is composed of a pressing body 41 and a pressing rod 42. The pressing rod 42 is arranged at one end of the pressing body 41. The other end of the pressing body 41 is provided with a mounting hole 43 and a countersunk hole 44. The mounting hole 43 is connected to the countersunk hole 44. A fixing sleeve 45 is also provided at the mounting hole 43. The outside of the fixing sleeve 45 is provided with a first tooth 46. A through hole 47 is formed in the middle of the fixing sleeve 45.

[0055] The movable member 6 is provided with a fixing hole 48 that matches with the fixing sleeve 45, and the inner wall of the fixing hole 48 is provided with a second tooth 49 that matches with the first tooth 46. A cylinder 50 is provided in the middle of the fixing hole 48, and a second threaded hole 51 is formed in the middle of the cylinder 50. A second bolt 52 that matches with the second threaded hole 51 is provided in the mounting hole 43, and the second bolt 52 passes through the mounting hole 43 and the through hole 47 and matches with the second threaded hole 51.

[0056] The pressing member 5 is mounted on the movable member 6 by the second bolt 52, and the position between the pressing member 5 and the movable member 6 is limited by the cooperation of the first tooth 46 and the second tooth 49. When the first adapter end 1 and the second adapter end 2 are docked, the second bolt 52 can be loosened, and the two pressing members 5 are rotated in opposite directions, so that the pressing rod 42 is rotated to contact the extension section 22, thereby achieving the limiting effect on the movable member 6. Since the diameter of the docking chamber 15 is small, it is impossible to push the movable member 6 by inserting a finger into the docking chamber 15, so the pressing member 5 in contact with the extension section 22 can effectively limit the position of the movable member 6, and will not cause the movable member 6 to be rotated, thereby compressing the tension spring 7.

[0057] like Fig.10 As shown, the tension spring 7 is now in a state of being compressed by the movable part 6, and the distance between the locking tooth 12 on the retaining part 9 and the center line of the fixed end 14 is smaller than the inner diameter of the first annular portion 13, and the second adapter end 2 is in a state of docking with the first adapter end 1. The symmetrically arranged pressing parts 5 are in a state of not being pushed by the driving part 4. When the driving part 4 is inserted between the pressing parts 5 and the pressing parts 5, the symmetrically arranged pressing parts 5 can be pushed by the driving part 4, so that the symmetrical pressing parts 5 rotate in opposite directions, driving the movable parts 6 connected to each other to rotate, and compressing the tension spring 7. The assembly structure is adopted and wrapped inside, which does not affect the mold opening and also improves the aesthetics of the adapter.

[0058] When the docking assembly 3 is placed in the docking chamber 15, the movable member 6 can be pushed under the elastic force of the tension spring 7, so that the symmetrical pressing members 5 are close to each other, and at the same time, the movable member 6 drives the retaining member 9 to move in the one-way recess 23, thereby guiding the lower part of the inclined surface 8 to move to the higher part, and the cylinder 31 will move outward, and the movable body 32 will move in the moving groove 33 to compress the spring 35. The elastic force of the spring 35 here is smaller than the elastic force of the tension spring 7. In this way, the locking tooth 12 can penetrate into the inner wall of the docking chamber 15, and a locking groove that cooperates with the locking tooth 12 can also be set in the inner wall of the docking chamber 15 for locking. At the same time, the locking tooth 12 is restricted in the docking chamber 15 by the first annular portion 13, which improves the stability of the connection between the first adapter end 1 and the second adapter end 2.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
