Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an optical fiber installation device. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total internal reflection of light". Often, the two terms optical fiber and optical cable are confused. Most optical fibers must be covered with several layers of protective structure before use. The covered cable is called optical cable. Household optical fiber is generally installed on routers and optical modems, and optical modems are usually placed inside multimedia boxes.

[0003] When optical fiber is in use, one end of the optical fiber is usually fixed with a connector, which makes it convenient to connect the connecting device to the optical fiber line. However, when not in use, the connector is exposed to the outside. If it is not covered, dust may enter the connector and cause poor contact or damage to the connector. Utility Model Content

[0004] The purpose of the present utility model is to provide an optical fiber installation device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An optical fiber installation device includes an optical fiber body, a connector is fixedly installed on the left side of the optical fiber body, a protective mechanism is provided on the outer wall of the connector, and a clamping mechanism is provided on the left side of the connector. The protective mechanism includes:

[0007] A support rod, the back of which is fixedly mounted on the front of the connector, a positioning spring being fixedly mounted in the hole of the support rod, capable of causing the positioning block to reset after being squeezed, so that it is inserted into the positioning hole, thereby fixing the protective cover to the support rod, a positioning block being fixedly mounted on one end of the positioning spring away from the support rod, and an outer wall of the positioning block being slidably mounted in the hole of the support rod;

[0008] The protective cover is slidably mounted on the back of the support rod, and a positioning hole is provided on the top of the protective cover groove.

[0009] Preferably, a fixed block is fixedly installed on the left side of the protective cover to facilitate rotation and fix the initial position of the torsion spring to prevent the rotating rod from driving the torsion spring to rotate when rotating. A rotating rod is rotatably installed on the front of the fixed block, and a torsion spring is fixedly installed on the front of the fixed block. When the shield is not stuck by the connecting head, the torsion spring drives the rotating rod to reset and the shield is reset at the same time to block the left side of the connecting head.

[0010] Preferably, one end of the torsion spring away from the fixing block is fixedly mounted on the outer wall of the rotating rod, and a shield is fixedly mounted on the outer wall of the rotating rod.

[0011] Preferably, the clamping mechanism comprises: a mounting frame, the left side of the mounting frame is fixedly mounted on the right side of the support rod, and a moving rod is slidably mounted in a groove of the mounting frame.

[0012] Preferably, the top of the moving rod is hinged with a connecting rod, and the end of the connecting rod away from the moving rod is hinged with a pushing telescopic rod. Because the distance that the protective cover moves is too long and the distance between the arc-shaped clamping plate and the optical fiber body is short, the pushing telescopic rod can be retracted first and then the arc-shaped clamping plate can be pushed to move. The left side of the pushing telescopic rod is fixedly installed on the right side of the protective cover.

[0013] Preferably, a telescopic rod is fixedly mounted on the left side of the movable rod, an extrusion spring is fixedly mounted inside the telescopic rod to reset the compressed telescopic rod, and an arc-shaped splint is fixedly mounted on the left side of the telescopic rod.

[0014] Compared with the prior art, the present invention provides an optical fiber installation device with the following beneficial effects:

[0015] 1. When the connector needs to be used, pull the protective cover to disengage the positioning block from the current positioning hole and move it to the next positioning hole for fixation. During the movement, the shield will be squeezed by the connector, causing the rotating rod to rotate and the torsion spring to twist, so that the place where the connector is inserted into the connecting device is exposed. Conversely, move the protective cover back, the torsion spring will reset the rotating rod, and the shield will cover the connector. This can prevent dust from entering the interior of the connector, preventing the connector from poor contact or direct damage during use.

[0016] 2. By moving the protective cover as described above to open the shutter, the protective cover will push the telescopic rod, which will first shrink, and then push the connecting rod to move the two sets of moving rods toward the middle, while driving the arc-shaped clamping plate to clamp the optical fiber body. This can prevent the connector and the optical fiber body from excessive bending during installation, causing the optical fiber body to break. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an optical fiber installation device, comprising an optical fiber body 1, a connector 2 is fixedly installed on the left side of the optical fiber body 1, a protective mechanism 3 is provided on the outer wall of the connector 2, and a clamping mechanism 4 is provided on the left side of the connector 2.

[0024] Specifically, the protective mechanism 3 includes: a support rod 31, a positioning spring 32, a positioning block 33, a protective cover 34, a positioning hole 35, a fixing block 36, a rotating rod 37, a torsion spring 38, and a shield 39. The back of the support rod 31 is fixedly installed on the front of the connecting head 2, and a positioning spring 32 is fixedly installed in the hole of the support rod 31. The positioning spring 32 is fixedly installed on the end of the positioning spring 32 away from the support rod 31. The outer wall of the positioning block 33 is slidably installed in the hole of the support rod 31, the protective cover 34, and the protective cover 34 is slidably installed on the back of the support rod 31. A positioning hole 35 is provided on the top of the protective cover 34 groove. When the connecting head 2 needs to be used, the positioning block 33 is squeezed by pulling the protective cover 34, so that it moves into the hole of the support rod 31, and the positioning spring 32 is compressed. At this time, the positioning block 33 will be separated from the current positioning hole 35. When the protective cover 34 moves to the most When the cam 35 is in the closed position, the locking cam 36 is engaged with the locking cam 37 and the locking cam 38 is engaged with the locking cam 37. When the cam 35 is in the closed position, the locking cam 36 is engaged with the locking cam 37 and the locking cam 37 is engaged with the locking cam 37. When the cam 35 is in the closed position, the locking cam 36 is engaged with the locking cam 37 and the locking cam 37 is engaged with the locking cam 37.

[0025] Specifically, the clamping mechanism 4 includes: a mounting frame 41, a moving rod 42, a connecting rod 43, a pushing telescopic rod 44, a moving telescopic rod 45, an extrusion spring 46, and an arc-shaped clamping plate 47. The left side of the mounting frame 41 is fixedly mounted on the right side of the support rod 31. The moving rod 42 is slidably mounted in the groove of the mounting frame 41. The top of the moving rod 42 is hinged with a connecting rod 43. The end of the connecting rod 43 away from the moving rod 42 is hinged with a pushing telescopic rod 44. By moving the protective cover 34 in the above manner, the shield 39 is opened, and the protective cover 34 will push the telescopic rod 44. The pushing telescopic rod 44 will first retract, and then Then push the connecting rod 43 to make the two groups of moving rods 42 move toward the middle at the same time in the groove of the mounting frame 41, push the left side of the telescopic rod 44 to be fixed on the right side of the protective cover 34, and the left side of the moving rod 42 is fixedly installed with a moving telescopic rod 45, and the interior of the moving telescopic rod 45 is fixedly installed with an extrusion spring 46, and the left side of the moving telescopic rod 45 is fixedly installed with an arc-shaped clamping plate 47. When the moving rod 42 moves, it will drive the moving telescopic rod 45 to move, so that the arc-shaped clamping plate 47 clamps the optical fiber body 1, so as to prevent the connector 2 and the optical fiber body 1 from being excessively bent during installation.

[0026] Working principle: When the connector 2 needs to be used, the protective cover 34 is pulled to squeeze the positioning block 33, causing it to move into the hole of the support rod 31, and the positioning spring 32 is compressed. At this time, the positioning block 33 will disengage from the current positioning hole 35. When the protective cover 34 moves to the farthest end, the positioning block 33 is aligned with the positioning hole 35, and the positioning spring 32 will reset the positioning block 33 so that it is inserted into the aligned positioning hole 35, fixing the protective cover 34. When the protective cover 34 moves, the shield 39 will be squeezed by the connector 2, causing it to drive the rotating rod 37 to rotate, and the torsion spring 38 to twist until the shield 39 no longer blocks the insertion position of the connector 2. Conversely, the protective cover 34 is moved back, and the torsion spring 38 will reset the rotating rod 37, causing the shield 39 to cover the connector 2. This can prevent dust from entering the interior of the connector 2 and prevent the connector 2 from poor contact or direct damage during use.

[0027] By moving the protective cover 34 as described above, the shield 39 is opened, and the protective cover 34 will push the telescopic rod 44. The telescopic rod 44 will be retracted first, and then the connecting rod 43 will be pushed, so that the two sets of movable rods 42 will move toward the middle in the groove of the mounting frame 41 at the same time. When the movable rod 42 moves, it will drive the movable telescopic rod 45 to move, so that the arc-shaped clamping plate 47 clamps the optical fiber body 1. When the optical fiber body 1 is thicker, the arc-shaped clamping plate 47 has clamped the outer wall of the optical fiber body 1. At this time, the telescopic rod 44 is pushed and continued to be pushed, so that the movable rod 42 can squeeze the movable telescopic rod 45, compressing the movable telescopic rod 45 and compressing the extrusion spring 46. This can prevent the connector 2 and the optical fiber body 1 from being excessively bent during installation, causing the optical fiber body 1 to break.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
