Description

Technical Field

[0001] The utility model relates to the technical field of rack-type terminal boxes, in particular to a rack-type terminal box with a telescopic structure. Background Art

[0002] Fiber optic terminal box series products are auxiliary equipment for terminal wiring in fiber optic transmission communication networks. They are suitable for direct and branch connection of indoor optical fibers and protect optical fiber joints. Fiber optic terminal boxes are mainly used for fixing optical fiber terminals, splicing optical fibers with pigtails, and storing and protecting remaining fibers.

[0003] The cover of the rack-mounted terminal box is usually fixed to the shell by screws. When coiling the fiber, it is necessary to loosen the screws and remove the cover, which is time-consuming and labor-intensive, and reduces work efficiency. Utility Model Content

[0004] In view of the technical problems in the prior art, the utility model provides a rack-type terminal box with a telescopic structure, aiming to solve the above problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rack-mounted terminal box with a telescopic structure comprises a box body, a mounting frame is arranged inside the box body, a sliding cavity is opened on the front side of the box body corresponding to the mounting frame, the lower side wall of the sliding cavity is slidably connected to the bottom of the mounting frame, handles are hinged at the left and right ends of the front side of the mounting frame, and placement grooves are opened on the left and right side walls of the box body corresponding to the two handles.

[0007] Preferably, slide rails are respectively arranged horizontally and longitudinally on the left and right sides of the bottom of the mounting frame, and limiting slide grooves slidably connected thereto are respectively arranged at the bottom of the sliding cavity corresponding to the two slide rails.

[0008] Preferably, a plurality of pulleys slidably connected thereto are evenly provided at the corresponding limiting slide grooves on the lower sides of the two slide rails.

[0009] Preferably, a limit block is provided at the top of the rear side wall of the mounting frame, and a stop block is fixedly provided at the top of the sliding cavity near the corresponding limit block on the front side.

[0010] Preferably, the left and right ends of the front side of the mounting frame extend outwardly to be arranged on a baffle abutting against the front side of the box body, the handle is hinged at the end of the baffle, and the handle can be rotated along the intersection to enter the placement slot.

[0011] Preferably, a torsion spring is provided at the hinge between the handle and the baffle.

[0012] Preferably, a handle groove is provided in the middle of the handle, and a clamping block is fixedly provided in the middle of the placement groove corresponding to the handle groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a rack-type terminal box with a telescopic structure. When it is necessary to coil the fiber, it is only necessary to rotate the handles in the placement grooves on both sides of the box body along the hinges, and then pull the mounting frame out of the sliding cavity through the slide rail and the pulley, and limit it at the stop block by connecting it to the stop block to prevent the mounting frame from slipping out of the sliding groove. After the fiber is coiled, the mounting frame is pushed back into the sliding cavity until the baffles on the left and right ends of the front side of the mounting frame abut against the front side of the box body. At this time, the handle is released, and the handle is rotated along the hinge position into the placement groove under the action of the torsion spring. At this time, the handle groove in the middle of the handle is just sleeved on the clamping block, which fixes the mounting frame and prevents the mounting frame from slipping out of the box body forward. The overall design is simple, and it is convenient to telescope when performing fiber coiling, which improves work efficiency. At the same time, the installed mounting frame has good stability and high practicality. BRIEF DESCRIPTION OF THE DRAWINGS
