[0027] As Figures 1-3The utility model provides a kind of optical fiber patch cord dynamic bending resistance and self-adapting curl structure shown, including protective box 1 and the box cover 2 connected on protective box 1, wire body 3 is placed in protective box 1, curling piece 5 is provided in protective box 1, and wire body 3 is curled and is received by curling piece 5.

[0028] In the utility model, the curling piece 5 in the protective box 1 can receive the wire body 3, to improve the convenience and protection of the wire body 3 during use.

[0029] In an optional embodiment, the curling piece 5 includes a rotating rod 51 that penetrates the protective box 1 at one end and is rotatably connected to the protective box 1. A winding drum 55 is slidably connected to the rotating rod 51. An abutting block 52 extends into the winding drum 55 from the outer side of the rotating rod 51. The wire body 3 is wound in the winding drum 55, and the end of the wire body 3 penetrates the protective box 1. A protective rubber sleeve 54 is fixedly connected to the end of the wire body 3 and is sleeved on the wire body. Two groups of mounting blocks 56 are fixedly connected to the inner wall of the protective box 1 and are used to support the protective rubber sleeve 54. A guide rod 53 is fixedly connected to the inner wall of the protective box 1 and is used to guide the wire body 3.

[0030] In this embodiment, the wire body 3 is dynamically curled and received in the protective box 1 by rotating the winding drum 55, which avoids damage to the wire body 3 during non-use and improves the protection of the wire body 3 in the protective box 1. When any end of the wire body 3 is pulled out to be used, the wire body 3 that extends out of the protective box 1 can be dynamically sleeved on the outer surface of the wire body 3 by extruding the protective rubber sleeve 54, which improves the bending resistance of the wire body 3 during use and improves the convenience and protection of the entire patch cord during use.

[0031] It should be noted that the protective rubber sleeve 54 is C-shaped, and the two groups of mounting blocks 56 are distributed in a staggered and symmetrical manner on the inner wall of the protective box 1. Support grooves are formed in the mounting blocks 56 for the sliding of the protective rubber sleeve 54. The support grooves are C-shaped, which allows the protective rubber sleeve 54 to be supported by the mounting blocks 56 while the winding drum 55 is lifted from the rotating rod 51. The protective rubber sleeve 54 and the wire body 3 can be pulled out together, which facilitates the replacement of different types of wire bodies 3 in the protective box 1 by the operator.

[0032] During the curling of the wire body 3 on the winding drum 55, the middle part of the wire body 3 is pressed on the winding drum 55 in a U-shaped manner, and the two ends are wound on the winding drum 55 in the same direction. During the forward rotation of the winding drum 55, the two ends of the wire body 3 can be wound, and during the reverse rotation, the two ends of the wire body 3 can be unwound.

[0033] The inner wall of the winding drum 55 is provided with a butt joint groove, and the butt joint groove is matched with the butt joint block 52 in size, so that the winding drum 55 on the rotating rod 51 can rotate together with the rotating rod 51 through the butt joint of the butt joint block 52 and the butt joint groove.

[0034] In addition, the inner wall of the protective box 1 is provided with a groove 57 for sliding of the wire body 3, and the groove 57 is U-shaped, so that the wire body 3 can slide through the groove 57 after penetrating the protective box 1, and the wire body 3 can slide out of the protective box 1 through the groove 57 after the box cover 2 is opened. The box cover 2 and the protective box 1 can be fixed by a conventional bolt connection.

[0035] Secondly, the curling piece 5 further comprises a push block 58 fixedly connected to one end of the rotating rod 51 penetrating the protective box 1, and the push block 58 is fixedly connected to an insertion block 59 extending into the protective box 1 on the side close to the protective box 1. A plurality of insertion slots are provided below the protective box 1, and the insertion slots are annularly and equidistantly distributed. The size of the insertion slot is matched with the size of the insertion block 59. The rotating rod 51 is supported and limited by the insertion block 59 extending into the insertion slot. Conversely, pulling the push block 58 drives the insertion block 59 to separate from the insertion slot, so that the rotating rod 51 is no longer limited, and the rotating rod 51 is rotated.

[0036] In an optional embodiment, the protective box 1 is provided with a support 4 for supporting. The support 4 comprises a support block 41 fixedly connected to the protective box 1, a clamping block 43 threadedly connected to the support block 41 above the box cover 2, and a vertical rod 44 fixedly connected to the support block 41 and penetrating the clamping block 43.

[0037] In this embodiment, when the clamping block 43 moves towards the side close to the protective box 1 through the threaded rod 42 on the protective box 1, the protective box 1 can be clamped and fixed around the optical modem, i.e. clamped on a conventional plate or block-shaped object. The stability of the protective box 1 and the wire body 3 is improved to improve the stability of the wire body 3 during use, thereby further improving the protection of the wire body 3.

[0038] It should be noted that a threaded hole is provided at the connection between the clamping block 43 and the threaded rod 42, and the threaded hole is matched with the threads on the outer side of the threaded rod 42, so that the rotating threaded rod 42 can adjust the up and down movement of the clamping block 43 on the vertical rod 44 along the vertical horizontal plane.

[0039] The working principle of the above embodiment is as follows:

[0040] The wire body 3 wound on the winding drum 55 can be wound on the winding drum 55 by the rotating winding drum 55, and is located in the protective box 1 to avoid the wire body 3 located in the protective box 1 from being bent by external force extrusion. After the push block 58 drives the plug block 59 to separate from the plug slot on the protective box 1, one end of the wire body 3 can be pulled to drive the winding drum 55 to rotate reversely, so that both ends of the wire body 3 can be simultaneously extended out of the protective box 3 for plug-in use. In the process of extending out of the protective box 3, the C-shaped protective rubber sleeve 54 can be extended out together, and the extended protective rubber sleeve 54 can be extruded and dynamically sleeved on the outer surface of the wire body 3 by the groove 57 to sleeve and protect the part of the wire body 3 extended out of the protective box 1, thereby improving the bending resistance of the part of the wire body 3 extended out of the protective box 1. After the both ends of the wire body 3 are plugged in, the push block 58 is pushed to drive the plug block 59 to be plugged into the plug slot of the protective box 1 to limit and support the rotating rod 51, so that the wire body 3 is more stable after plugging in to improve the protection of the wire body 3 in the protective box 1 and outside the protective box 1.

[0041] In the process of maintaining the wire body 3, the push rod 58 is pulled again, and then the winding drum 55 is rotated to rotate forward to wind the wire body 3. The end of the wire body 3 can be pulled to make the operator more convenient to find the end of the wire body 3 and pull out the end of the wire body 3, and the box cover 2 is opened to maintain or replace the wire body 3.

[0042] When the clamping block 43 moves towards the side close to the protective box 1 through the threaded rod 42 on the protective box 1, the protective box 1 can be clamped and fixed around the optical modem, that is, clamped on a regular plate or block-shaped object to stably support the protective box 1 and the wire body 3 to improve the stability of the wire body 3 in use. When it is not convenient to clamp and support, the protective box 1 can be directly placed.

[0043] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
