Description

Technical Field

[0001] The utility model relates to the field of optical fiber distribution cabinet equipment, in particular to an internal interconnection structure of an optical fiber distribution cabinet. Background Art

[0002] A fiber optic distribution cabinet is a transmission device used to realize functions such as distribution, scheduling and backup of optical fiber connectors and optical cables in a fiber optic communication system. It is a key device that is connected to a main control device and a terminal device by one or more optical cables, and ultimately realizes the transmission of optical signals to the terminal device. The interconnection structure inside the fiber optic distribution cabinet refers to the components used to arrange the optical fibers inside the fiber optic distribution cabinet, including guide rails, trays and wiring boards. When using guide rails for optical fiber arrangement operations, a plurality of through holes are usually opened on the surface of the guide rails. The optical fibers are arranged by passing the through holes opened on the surface of the guide rails, thereby facilitating the fiber laying operation of the optical fiber units inside the fiber optic distribution cabinet.

[0003] At present, when installing the guide rail inside the optical fiber distribution cabinet, the two ends of the guide rail are generally connected to the two sides inside the optical fiber distribution cabinet by multiple bolts, so as to facilitate the optical fiber to pass through the through hole on the surface of the guide rail. When the optical fiber unit inside the optical fiber distribution cabinet is used for fiber laying operation, it is necessary to adjust the installation position of the guide rail according to the position of the optical fiber unit inside the optical fiber distribution cabinet. When adjusting the position of the guide rail, it is necessary to remove multiple bolts before adjusting the position of the guide rail. Such operation is relatively cumbersome, which reduces the convenience of using the guide rail and reduces the operating efficiency of the staff when laying the fiber.

[0004] Therefore, it is necessary to provide a new fiber optic wiring cabinet internal interconnection structure to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a fiber optic wiring cabinet internal interconnection structure.

[0006] The fiber optic wiring cabinet internal interconnection structure provided by the utility model comprises a fiber optic wiring cabinet body and a guide rail for arranging optical fibers, and is characterized in that a clamping assembly for limiting the guide rail is provided inside the fiber optic wiring cabinet body;

[0007] The clamping assembly includes a support member and two limit rods, both ends of the support member are respectively fixedly connected to the top and bottom ends inside the fiber optic wiring cabinet body, both sides inside the support member are provided with sliding grooves matching one end of the limit rods, the limit rods are arranged in an L-shape, one end of the two limit rods are respectively located inside the two sliding grooves, the ends of the two limit rods away from the sliding grooves are respectively fixedly connected to one side of the guide rail, the end of the limit rod located inside the sliding groove is provided with a storage groove, and an elastic member is fixedly connected to the inner side of the storage groove, the other end of the elastic member is fixedly provided with a clamping block, and a plurality of clamping grooves matching the clamping block are provided on the inner side of the sliding groove, and the top of the end of the clamping block away from the elastic member is inclined.

[0008] Preferably, the elastic member is a spring, one end of the spring is fixedly connected to the inner side of the receiving groove, and the other end of the spring is fixedly connected to one end of the locking block.

[0009] Preferably, the support member includes two support rods of the same structure, both ends of the support rods are respectively fixedly connected to the top and bottom ends inside the fiber optic distribution cabinet body, and one side of the support rod is provided with a slide groove matching one end of the limit rod, and the inner side of the slide groove is provided with a plurality of card grooves matching the locking block.

[0010] Preferably, a reset member is provided on the top of the locking block, and the reset member includes a connecting rod, the bottom of the connecting rod is fixedly connected to the top of the locking block, and the top of the limiting rod is provided with a fixing groove for the connecting rod to move, and the fixing groove is communicated with the storage groove.

[0011] Preferably, a pull rod is provided on the top of the connecting rod.

[0012] Preferably, a wiring board is provided between the two support rods, and a plurality of through grooves for optical fibers to pass through are provided on the surface of the wiring board.

[0013] Compared with the related art, the interconnection structure in the optical fiber distribution cabinet provided by the utility model has the following beneficial effects:

[0014] The guide rail is pulled upward so that one end of the two limit rods provided on one side of the guide rail slides in the two slide grooves respectively, and at the same time, the inclined surface provided at one end of the engaging block contacts the top of the inner side of the engaging groove. Because one end of the engaging block is connected to the elastic member, when the inclined surface provided at one end of the engaging block contacts the top of the inner side of the engaging groove, the engaging block will move toward the inside of the storage groove due to being squeezed, so that one end of the limit rod can move upward in the slide groove, thereby adjusting the position of the guide rail. The above structure can be used to quickly adjust the position of the guide rail, which improves the convenience of using the guide rail to a certain extent, and at the same time improves the operating efficiency of the staff when laying fibers.
