[0063] Example

[0064] This embodiment provides an optical fiber mount, such as Figures 1 to 3 As shown, it includes a base 1, a base shell 2, an end cap 4, a top block 5, a locking element 6, a seat sleeve 7, an elastic element 8, and a top ring 9. The optical fiber 3 passes through the end cap 4 and is inserted into the base shell 2. The direction from the end cap 4 to the base 1 is the insertion direction of the optical fiber 3.

[0065] Among them, such as Figure 2 As shown, the base 1 has an annular through hole in the middle, the seat sleeve 7 is located in the annular through hole and can rotate freely in the annular through hole, and the bottom outer surface of the base 1 extends outward to increase the stability of the base 1.

[0066] like Figure 3 As shown, the bottom of the seat sleeve 7 is annular and located within the annular through hole in the middle of the base 1. The second fixing part 71 on the upper part of the seat sleeve 7 is columnar and located in the middle of the annular bottom of the seat sleeve 7. The top ring 9 has an annular through hole inside, and the top ring 9 is fitted onto the seat sleeve 7 through the annular through hole and can rotate relative to the seat sleeve 7. Three second claws 92 are provided around the top ring 9, and the second claws 92 are elastic elements. The upper surface of the top ring 9 has three equally spaced second arc-shaped grooves 91, and there is a gap between two adjacent second arc-shaped grooves 91. Along the insertion direction of the optical fiber 3, that is... Figure 3The upper surface of the middle top ring 9 is directed to the lower surface direction, and the starting end of any second arc-shaped groove 91 is lower than the ending end, that is, the second arc-shaped groove 91 is sloped, and the starting end and the ending end of the adjacent two second arc-shaped grooves 91 are close to each other.

[0067] As shown in Figure 3 and Figure 11 , the bottom of the locking piece 6 is provided with three second protrusions 63, and the three second protrusions 63 are arranged in the three second arc-shaped grooves 91 respectively, so that there is a gap between the first fixing part 61 at the top of the locking piece 6 and the second fixing part 71 at the upper part of the seat sleeve 7. It can be understood that by arranging the starting end of any second arc-shaped groove 91 to be lower than the ending end, when the top ring 9 is rotated, the second arc-shaped groove 91 will slide with the second protrusion 63 and lift the second protrusion 63, thereby lifting the locking piece 6.

[0068] As shown in Figure 2 and Figure 4 , the middle of the top block 5 is provided with a through hole, and the top block 5 is sleeved on the locking piece 6 through the through hole. The inner wall of the top end of the top block 5 is protruded inward to form an annular stop block, as shown in Figure 10 , the outer surface of the bottom of the locking piece 6 is protruded outward to form a bottom flange, and a placing cavity is formed between the bottom flange and the annular stop block. The elastic piece 8 is sleeved on the outer surface of the locking piece 6 and arranged in the placing cavity. One end of the elastic piece 8 abuts against the annular stop block, and the other end of the elastic piece 8 abuts against the bottom flange. By arranging the elastic piece 8, when the top block 5 moves in the direction of inserting the optical fiber 3, the elastic piece 8 will be compressed, so that the elastic piece 8 has an elastic force to drive the locking piece 6 to move in the direction of inserting the optical fiber 3, thereby driving the locking piece 6 to move in the direction of inserting the optical fiber 3.

[0069] As shown in Figure 9 and Figure 10 , three limiting blocks 53 are arranged on the side wall of the through hole in the middle of the top block 5, and three first limiting grooves 62 are arranged on the outer surface of the locking piece 6 correspondingly. When the top block 5 is installed, the three limiting blocks 53 are inserted into the three first limiting grooves 62 respectively, so that the top block 5 can move up and down relative to the outer surface of the locking piece 6, while the rotation of the top block 5 relative to the locking piece 6 is limited. Further, the bottom of the through hole in the middle of the top block 5 is provided with three first clamping claws 52. When installed, the top block 5 is pressed in the direction of inserting the optical fiber 3 until the first clamping claws 52 are clamped into the lower surface of the bottom flange of the locking piece 6, thereby preventing the top block 5 from moving in the direction of pulling out the optical fiber 3 without driving the locking piece 6 to move together, and preventing the top block 5 from separating from the locking piece 6.

[0070] As shown in Figure 3 , Figure 10 and Figure 11As shown, the locking member 6 is provided with a rectangular through hole in the middle, the seat cover 7 is provided with a rectangular groove, the rectangular through hole and the rectangular groove are the same shape as the fixed part on the optical fiber 3, when the optical fiber 3 needs to be inserted, the locking member 6 is rotated to align the rectangular through hole with the rectangular groove, and then the fixed part on the optical fiber 3 can be inserted into the rectangular through hole and placed in the rectangular groove, so that the fixed part on the optical fiber 3 is between the first fixed part 61 of the locking member 6 and the second fixed part of the seat cover 7, and then the locking member 6 is rotated again to misalign the rectangular through hole with the fixed part on the optical fiber 3, thereby preventing the optical fiber 3 from sliding out.

[0071] As shown in Figure 2 and Figure 9 , the top block 5 is provided with a driving adapter on the top surface of the top block 5, the driving adapter is three first arc-shaped grooves 51 arranged at equal intervals, and there is a gap between any two adjacent first arc-shaped grooves 51, along the direction of insertion of the optical fiber 3, that is Figure 9 , the top surface of the top block 5 points to the lower surface, the starting end height of any first arc-shaped groove 51 is lower than the ending end height, that is, the first arc-shaped groove 51 is sloped, and the starting end and the ending end of the adjacent two first arc-shaped grooves 51 are close to each other.

[0072] As shown in Figure 2 , Figure 7 and Figure 8 , the base shell 2 is provided with a through hole inside, and the lower opening of the through hole is larger than the upper opening, the base shell 2 is provided with three stoppers 23, the stopper 23 is a through hole provided on the side surface of the base shell 2, during installation, the base shell 2 is buckled on the outer surface of the top block 5 through the lower opening, and the stopper 23 is clamped with the second claw 92 on the top ring 9, thereby realizing synchronous rotation of the base shell 2 and the top ring 9.

[0073] As shown in Figure 8 , the base shell 2 is provided with a driving part, the driving part is three first protrusions 22 provided on the inner wall above the base shell 2, the three first protrusions 22 are arranged at equal intervals, and the three first protrusions 22 are arranged in the three first arc-shaped grooves 51. It can be understood that, since the starting end height of any first arc-shaped groove 51 is lower than the ending end height, when the base shell 2 rotates, the first protrusion 22 will push the top block 5 to move in the direction of insertion of the optical fiber 3 during the movement of the first protrusion 22 from the starting end to the ending end in the first arc-shaped groove 51, so that the movement of the top block 5 in the direction of insertion of the optical fiber 3 will compress the elastic member 8, so that the elastic member 8 has the elastic force of driving the locking member 6 to move in the direction of insertion of the optical fiber 3, thereby driving the locking member 6 to move in the direction of insertion of the optical fiber 3, so that the first fixed part 61 is close to the second fixed part 71 to clamp the fixed end of the optical fiber 3. By arranging three first protrusions 22 and first arc-shaped grooves 51 at equal intervals, the force on the top block 5 is uniform. The base shell 2 is also provided with a clamping part 21, the clamping part 21 is three third claws provided on the outer surface of the base shell 2.

[0074] AsFigure 5 and Figure 6 As shown in the figure, the end cover 4 includes a clamping adapter 41 for connecting with the clamping part 21, the clamping adapter 41 is three through slots provided on the end cover 4, and the end cover 4 and the base shell 2 can be fixed in the direction of the optical fiber 3 insertion by clamping the third clamping jaw with the through slot. The end cover 4 is also provided with a limiting part 42 inside, which is three protrusions provided on the side wall of the end cover 4. Figure 7 As shown in the figure, the outer surface of the base shell 2 is also provided with three second limiting grooves 24, which are inserted with the protrusions, thereby ensuring that the end cover 4 can drive the base shell 2 to rotate together. The outer side of the end cover 4 is provided with a plurality of patterns to improve the friction of the outer side of the end cover 4, and a flat thrust bearing is provided below the top ring 9, which can make the top ring 9 rotate lightly and reduce resistance.

[0075] As shown in the figure, Figure 1 , Figure 3 and Figure 4 The seat sleeve 7 is provided with a through hole in the middle, and one end of the contact sheet 101 is fixed to the side wall of the through hole, and the other end of the contact sheet 101 extends out of the base 1. Since the head of the optical fiber 3 is metal and can conduct electricity, the contact sheet 101 is provided inside the optical fiber seat, and the line can be turned on and off during the plugging and unplugging of the optical fiber 3.

[0076] The optical fiber seat provided in the embodiment, when assembled, first place the seat sleeve 7 in the base 1, then set the top ring 9 on the seat sleeve 7 and place the flat thrust bearing between them, then set the elastic piece 8 on the surface of the locking piece 6, then install the locking piece 6 above the top ring 9, and the second protrusion 63 is at the starting end of the second arc-shaped groove 91, the rectangular hole on the locking piece 6 is aligned with the rectangular groove on the seat sleeve 7, then set the top block 5 on the surface of the locking piece 6, then set the base shell 2 on the surface of the top block 5, and the stopper 23 of the base shell 2 is connected with the second clamping jaw 92 of the top ring 9, then clamp the end cover 4 on the base shell 2, thus completing the assembly of the optical fiber seat. This scheme completely realizes the buckle type connection, without the need for screw tightening, making the assembly more convenient and fast.

[0077] When fixing the optical fiber 3, first rotate the end cover 4 to drive the base shell 2 to rotate, and the base shell 2 drives the top ring 9 to rotate so that the second protrusion 63 is at the starting end of the second arc-shaped groove 91, and then continue to rotate the end cover 4 to drive the locking piece 6 to rotate through the cooperation of the second protrusion 63 and the second arc-shaped groove 91 until the rectangular through hole on the locking piece 6 is aligned with the rectangular groove on the seat sleeve 7; then place the fixed end of the optical fiber 3 through the rectangular through hole in the rectangular groove on the seat sleeve 7, at this time the fixed end of the optical fiber 3 is arranged between the first fixing part 61 and the second fixing part 71, and then continue to rotate the end cover 4 to drive the base shell 2 to rotate until the rectangular through hole is misaligned with the fixed end of the optical fiber 3; then rotate the end cover 4 in the opposite direction of the above rotation direction to make the first protrusion 22 move from the starting end to the ending end of the first arc-shaped groove 51, so that the top block 5 moves in the direction of insertion of the optical fiber 3 and is compressed by the elastic piece 8, so that the elastic piece 8 has an elastic force to drive the locking piece 6 to move in the direction of insertion of the optical fiber 3, and then drive the locking piece 6 to move in the direction of insertion of the optical fiber 3, so that the first fixing part 61 moves close to the second fixing part 71 to clamp the fixed end of the optical fiber 3.

[0078] When pulling out the optical fiber 3, rotate the end cover 4 to drive the base shell 2 to rotate so that the first protrusion 22 moves from the ending end to the starting end of the first arc-shaped groove 51, and since the top ring 9 rotates at the same time, the second arc-shaped groove moves from the starting end to the ending end, and then the locking piece 6 is lifted by the second protrusion 63, and then the first fixing part 61 moves away from the second fixing part 71 to loosen the optical fiber 3, which is convenient for pulling out.

[0079] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
