[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, it is a structural diagram of an optical fiber quick connector provided by an embodiment of the present invention, including a socket 1 and a plug 2, the socket 1 is installed with a first optical fiber 11, the plug 2 is installed with a second optical fiber 21, the side wall of the socket 1 is provided with a socket 3 that cooperates with the plug 2, a plurality of groups of positioning blocks 4 distributed in an annular shape are fixedly installed on the surface of the plug 2, the socket 3 is provided with a positioning groove 5 that cooperates with the positioning block 4, the positioning groove 5 is composed of a transverse groove 51 and a longitudinal groove 52, the transverse groove 51 is provided with a plurality of groups and is distributed in an annular shape on the side wall of the socket 3, the longitudinal groove 52 is distributed on the side wall of the socket 3 and is connected with one end of the transverse groove 51 facing the inside of the socket 3, a clamping column 7 is provided in the longitudinal groove 52, the side wall of the positioning block 4 is provided with a clamping groove 8 that cooperates with the clamping column 7, a disassembly and assembly mechanism 6 that cooperates with the plug 2 is provided in the socket 1, and the disassembly and assembly mechanism 6 includes a fixing component 61 and a disassembly component Component 62, the fixing component 61 includes a clamping portion 611 and a first adjusting portion 612, the clamping portion 611 is located in the longitudinal groove 52 and is connected to the clamping column 7, the first adjusting portion 612 is located in the socket 1 and is connected to the clamping portion 611, when the positioning block 4 moves in the longitudinal groove 52, the first adjusting portion 612 controls the clamping column 7 to move in the longitudinal groove 52 by cooperating with the clamping portion 611, and thus adjusts the relative position of the clamping column 7 and the clamping groove 8, the disassembly component 62 includes a push plate 621, a telescopic portion 622 and a second adjusting portion 623, the push plate 621 is slidably installed in the clamping groove 8, the telescopic portion 622 is located at the bottom of the clamping groove 8, the second adjusting portion 623 is located in the plug 2 and is connected to the telescopic portion 622, and the second adjusting portion 623 controls the push plate 621 to slide in the clamping groove 8 by cooperating with the telescopic portion 622.

[0025] Initially, the socket 1 is separated from the plug 2. When the first optical fiber 11 and the second optical fiber 21 need to be connected, the positioning block 4 on the surface of the plug 2 is aligned with the transverse groove 51 on the surface of the socket 1, and the plug 2 is inserted into the jack 3. At this time, the positioning block 4 moves synchronously in the transverse groove 51. When the plug 2 moves to the limit depth in the jack 3, the plug 2 is rotated on the surface of the socket 1. The positioning block 4 on the surface of the plug 2 moves from the transverse groove 51 to the longitudinal groove 52 and moves synchronously in the longitudinal groove 52. When the positioning block 4 moves in the longitudinal groove 52, the first adjustment portion 612 cooperates with the clamping portion 611. The clamping column 7 is controlled to move to the outside of the longitudinal groove 52 in a manner. After the positioning block 4 rotates to the limit position in the longitudinal groove 52, the plug 2 stops rotating on the surface of the socket 1. The first adjusting portion 612 controls the clamping column 7 to be inserted into the clamping groove 8 on the surface of the positioning block 4 by cooperating with the clamping portion 611. The clamping column 7 cooperates with the clamping groove 8 to conveniently fix the positioning block 4 in the longitudinal groove 52, and then the plug 2 can be stably fixed in the socket 3. The plug 2 will not loosen in the socket 3, and even if the plug 2 is subjected to external tension, the plug 2 will not fall out of the socket 3. When the plug 2 needs to be pulled out from the surface of the socket 1, the second adjustment portion 623 cooperates with the telescopic portion 622 to control the push plate 621 to slide in the socket 3. The push plate 621 pushes the clamping column 7 to move toward the outside of the socket 3 and thus controls the clamping column 7 to separate from the clamping groove 8. At this time, the clamping column 7 releases the restriction on the positioning block 4 and rotates the plug 2 in the opposite direction on the surface of the socket 1. At this time, the positioning block 4 moves synchronously in the longitudinal groove 52 toward the transverse groove 51. When the positioning block 4 moves to the transverse groove 51, the positioning block 4 moves in the transverse groove 51, and the plug 2 can be easily pulled out from the socket 1.

[0026] like Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the clamping portion 611 includes a telescopic hole 6111 opened on the side wall of the longitudinal groove 52, the clamping column 7 is slidably installed in the telescopic hole 6111, and a first extrusion spring 6112 is fixedly installed in the telescopic hole 6111, and the telescopic end of the first extrusion spring 6112 is connected to the clamping column 7.

[0027] Initially, the first extrusion spring 6112 applies a thrust to the clamping column 7, and the clamping column 7 extends into the longitudinal groove 52. When the positioning block 4 slides from the transverse groove 51 to the longitudinal groove 52, the first adjustment portion 612 first applies a pulling force to the clamping column 7 and then moves the clamping column 7 as a whole into the telescopic hole 6111. When the positioning block 4 slides in the longitudinal groove 52, the clamping column 7 will not interfere with the positioning block 4. When the positioning block 4 moves to the extreme position in the longitudinal groove 52, the first adjustment portion 612 releases the pulling force on the clamping column 7. The first extrusion spring 6112 applies a thrust to the clamping column 7, and the clamping column 7 extends into the longitudinal groove 52. The clamping column 7 is inserted into the clamping groove 8 on the surface of the positioning block 4. The clamping column 7 cooperates with the clamping groove 8 to conveniently fix the positioning block 4 in the longitudinal groove 52, and then fix the plug 2 in the socket 3.

[0028] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the first adjusting portion 612 includes an arc-shaped slide groove 6121 opened on the side wall of the longitudinal groove 52, and a control block 6124 is slidably installed in the slide groove 6121, and the control block 6124 is made of magnetic material. The inner wall of the telescopic hole 6111 is provided with a first wire groove 6122 connected with the slide groove 6121 toward the socket 1, and the end of the clamping column 7 located in the telescopic hole 6111 is fixedly installed with a first traction rope 6123, the first traction rope 6123 passes through the first wire groove 6122 and extends into the slide groove 6121 and is connected to the control block 6124, the first traction rope 6123 is made of elastic material, and a second extrusion spring 6125 is fixedly installed at one end of the slide groove 6121 close to the clamping column 7, and the telescopic end of the second extrusion spring 6125 is connected to the control block 6124, and a magnetic sheet 6126 that cooperates with the control block 6124 is fixedly installed on the surface of the clamping column 7.

[0029] Initially, the second extrusion spring 6125 applies a thrust to the control block 6124, and the control block 6124 is at one end of the longitudinal groove 52 close to the transverse groove 51. When the positioning block 4 slides from the transverse groove 51 into the longitudinal groove 52, the magnetic sheet 6126 on the surface of the positioning block 4 is connected to the control block 6124 as a whole through magnetic attraction. When the positioning block 4 moves, it drives the control block 6124 to move synchronously in the slide groove 6121. The control block 6124 cooperates with the first traction rope 6123 to pull the card. The connecting column 7 moves toward the telescopic hole 6111. When the positioning block 4 moves to the extreme position in the longitudinal groove 52, the magnetic sheet 6126 on the surface of the positioning block 4 is separated from the control block 6124, and the control block 6124 moves back to its original position in the slide groove 6121. At this time, the first extrusion spring 6112 applies a thrust to the clamping column 7, and the clamping column 7 is inserted into the clamping groove 8 on the surface of the positioning block 4, so that the positioning block 4 can be conveniently fixed in the longitudinal groove 52, and then the plug 2 can be fixed in the socket 3.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the telescopic portion 622 includes a mounting hole 6221 formed in the bottom wall of the clamping slot 8, a push rod 6222 is slidably installed in the mounting hole 6221, a bottom groove 6223 is formed in the bottom wall of the mounting hole 6221, a connecting block 6224 is slidably installed in the bottom groove 6223, the connecting block 6224 extends into the mounting hole 6221 and is connected to the push rod 6222, a third extrusion spring 6225 is fixedly installed at one end of the bottom groove 6223 close to the clamping slot 8, and the telescopic end of the third extrusion spring 6225 is connected to the connecting block 6224.

[0031] Initially, the locking column 7 is inserted into the locking groove 8. When the plug 2 needs to be unplugged, the second adjustment portion 623 applies a pulling force to the connecting block 6224, thereby controlling the connecting block 6224 to move in the bottom groove 6223. The connecting block 6224 drives the push rod 6222 to move toward the locking groove 8. At this time, the push rod 6222 applies a thrust to the push plate 621, and the push plate 621 slides in the locking groove 8. The push plate 621 pushes the locking column 7 to move toward the outside of the locking groove 8, thereby controlling the locking column 7 and the positioning block 4 to separate from each other.

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, as a preferred embodiment of the present invention, the second adjustment part 623 includes a second wire groove 6231 opened in the plug 2 and connected with the bottom groove 6223, a second traction rope 6232 is fixedly installed on the side wall of the connecting block 6224, and a control ring 6233 is slidably installed on the surface of the plug 2, and the second traction rope 6232 passes through the second wire groove 6231 and extends to the outside of the plug 2 and is connected to the control ring 6233.

[0033] When the plug 2 needs to be pulled out, the control ring 6233 is pulled to slide on the surface of the plug 2 , and the control ring 6233 cooperates with the second traction rope 6232 to pull the connecting block 6224 to move in the bottom groove 6223 .

[0034] like Figure 2 , Figure 4 As shown, as a preferred embodiment of the present invention, a guide wheel 9 that cooperates with the second traction rope 6232 is rotatably installed in the second wire groove 6231.

[0035] like Figure 2 , Figure 4 As shown, as a preferred embodiment of the present invention, the side wall of the clamping groove 8 is provided with a limiting groove 10, and the side wall of the push plate 621 is fixedly installed with a limiting block 12 that is slidably connected to the limiting groove 10. The limiting block 12 cooperates with the limiting groove 10 to effectively improve the stability of the push plate 621 when sliding.

[0036] The working principle of the present invention is as follows: initially, the socket 1 is separated from the plug 2. When the first optical fiber 11 and the second optical fiber 21 need to be connected, the positioning block 4 on the surface of the plug 2 is aligned with the transverse groove 51 on the surface of the socket 1, and the plug 2 is inserted into the socket 3. At this time, the positioning block 4 moves synchronously in the transverse groove 51. When the plug 2 moves to the limit depth in the socket 3, the plug 2 is rotated on the surface of the socket 1, and the positioning block 4 on the surface of the plug 2 moves from the transverse groove 51 to the longitudinal groove 52 and moves synchronously in the longitudinal groove 52. When the positioning block 4 moves in the longitudinal groove 52, the magnetic sheet 6126 on the surface of the positioning block 4 is connected to the control block 6124 as a whole through magnetic attraction. When the positioning block 4 moves, it drives the control block 6124 to move synchronously in the slide groove 6121. The control block 6124 cooperates with the first traction rope 6123 to pull the clamping column 7 toward the telescopic hole 6111 and move the clamping column 7 as a whole into the telescopic hole 6111. When the positioning block 4 slides in the longitudinal groove 52, the clamping column 7 will not interfere with the positioning block 4. When the positioning block 4 moves to the limit position in the longitudinal groove 52, the magnetic sheet 6126 on the surface of the positioning block 4 and the control block 6124 are separated from each other, and the control block 6124 moves back to the original position in the slide groove 6121. At this time, the first extrusion spring 6112 applies a thrust to the clamping column 7, and the clamping column 7 is inserted into the clamping groove 8 on the surface of the positioning block 4, so that the positioning block 4 can be conveniently fixed in the longitudinal groove 52, and then the plug 2 is fixed in the socket 3. The plug 2 will not be loose in the socket 3, and even if the plug 2 is subjected to external tension, the plug 2 will not fall from the socket 3.

[0037] When the plug 2 needs to be pulled out from the surface of the socket 1, the control ring 6233 is pulled to slide on the surface of the plug 2, and the control ring 6233 cooperates with the second traction rope 6232 to pull the connecting block 6224 to move in the bottom groove 6223. The connecting block 6224 drives the push rod 6222 to move into the clamping groove 8. At this time, the push rod 6222 applies a thrust to the push plate 621, and the push plate 621 slides in the clamping groove 8. The push plate 621 pushes the clamping column 7 to move toward the outside of the clamping groove 8, thereby controlling the clamping column 7 and the positioning block 4 to separate from each other. At this time, the clamping column 7 releases the restriction on the positioning block 4, and the plug 2 is rotated in the opposite direction on the surface of the socket 1. At this time, the positioning block 4 moves synchronously in the longitudinal groove 52 toward the direction of the transverse groove 51. When the positioning block 4 moves to the transverse groove 51, the positioning block 4 moves in the transverse groove 51, and the plug 2 can be easily pulled out from the socket 1.

[0038] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
