Description

Technical Field

[0001] The utility model relates to the field of optical fiber distribution box equipment, in particular to an optical fiber distribution box which is easy to disassemble. Background Art

[0002] The optical fiber distribution box (ODB) is suitable for the wiring connection between optical cables and optical communication equipment. Through the adapter in the distribution box, the optical signal is led out with an optical jumper to realize the optical wiring function. It is suitable for the protective connection between optical cables and wiring pigtails, and is also suitable for use at optical fiber terminal points in optical fiber access networks. During the use of existing optical fiber distribution boxes, most of the distribution boxes are installed outdoors and are often fixed to the wall by bolts and other means. The outdoor environment is relatively harsh. Bolts and other exposed metal components will cause certain rust when they are blown by wind and snow. As a result, when the distribution box is disassembled for maintenance, the rusted bolts are not convenient for disassembly of the distribution box, causing inconvenience to the maintenance work. For this reason, we propose an optical fiber distribution box that is easy to disassemble. Utility Model Content

[0003] In view of this, the utility model provides an optical fiber distribution box that is easy to disassemble. The driving rod can be rotated to drive the round table to move back and forth in the connecting sleeve. The diameter of the round table increases from small to large. The limit baffle can be squeezed by moving the round table to squeeze the limit baffle out of the connecting sleeve so that the limit baffle is stuck in the groove to limit the connecting sleeve. When disassembling, the reset plate squeezes the limit baffle to make the limit baffle re-enter the connecting sleeve.

[0004] In order to solve the above technical problems, the utility model provides an easily disassembled optical fiber distribution box, including a box body, which is used to connect optical fibers. A connecting sleeve is connected to one side of the box body, and the connecting sleeve is connected to a mounting plate. Limit baffles are symmetrically arranged in the connecting sleeve, and the limit baffles are used to fix the connecting sleeve in the mounting hole. A round table is slidably arranged in the connecting sleeve, and the round table is used to squeeze the symmetrically arranged limit baffles, squeeze the limit baffles out of the connecting sleeve, and support the limit baffles to prevent the limit baffles from falling into the connecting sleeve during use. The round table is located in the middle position of the symmetrically arranged limit baffles. A driving rod for driving the round table to slide is rotatably provided on the box body, and the driving rod is used to drive the round table to move in the connecting sleeve, and push the limit baffle out of the connecting sleeve. A mounting plate is provided on one side of the box body, and the mounting plate is used to set the mounting hole.

[0005] A limiting groove matching the limiting baffle is provided on the connecting sleeve, the limiting groove is used to limit the limiting baffle to prevent the limiting baffle from deviating when moving up and down, and the limiting baffle is slidably arranged in the limiting groove.

[0006] The connecting sleeve is provided with sliding grooves symmetrically on the left and right sides, and the sliding grooves are used to limit the connecting block, so that when the driving rod drives the round table to move, the round table can move with the sliding grooves. A connecting block is connected to the round table, and the connecting block is used to connect the round table and limit the round table so that the round table is located in the middle position of the baffle, and the connecting block is slidably set in the sliding groove.

[0007] A thread is provided at one end of the driving rod, and a threaded hole matching the thread is provided on the round table. The thread is used to cooperate with the round table. When the driving rod rotates, the round table can move with the thread. The round table is rotatably set on the thread. The other end of the driving rod is set in a box body and a rotating handle is connected to the driving rod set in the box body. The rotating handle facilitates the driving rod to rotate.

[0008] A mounting hole is provided on the mounting plate. The mounting hole is concentrically arranged with the connecting sleeve. The mounting hole is used to place the connecting sleeve. A groove matching the length and width of the limit baffle is provided at the rear end of the mounting hole. The groove is used to clamp the limit baffle to prevent the connecting sleeve from rotating in the mounting hole.

[0009] Slots are symmetrically arranged on both sides of the groove, and the slots are used to limit the reset plate. A reset plate is slidably arranged in the slot, and the reset plate is used to squeeze the limit baffle into the connecting sleeve. The reset plate is fitted with the outer surface of the connecting rod.

The reset spring is used to provide a rebound elastic force to the reset plate so that the reset plate is always in contact with the surface of the connecting sleeve. One end of the reset spring is connected to the reset plate, and the other end of the reset spring is connected to the groove.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. Connect a connecting sleeve on the box body, insert the connecting sleeve into the mounting hole on the mounting plate, use the connecting sleeve to connect with the mounting hole to facilitate replacement of the box body, and slide a limit baffle in the connecting sleeve to fix the connecting sleeve with the mounting hole.

[0013] 2. A driving rod is provided for rotation inside the connecting sleeve. The driving rod is used to drive the round table to move, so that the limit baffle can be squeezed so that the limit baffle is stuck in the groove. The round table can support the limit baffle to prevent the limit baffle from falling into the connecting sleeve, and the connecting sleeve cannot be limited.

[0014] 3. When the box needs to be disassembled, rotate the driving rod to move the table to the side close to the box. The limit baffle loses the extrusion of the table. The reset plate in the groove returns to the connecting sleeve under the rebound of the reset spring, and then the connecting sleeve is pulled out of the mounting hole.

[0031] like Figure 2 , 3 , as shown in 4:

[0032] A mounting hole 106 is provided on the mounting plate 105, and the mounting hole 106 is clearance-matched with the connecting sleeve 101. The mounting hole 106 and the connecting sleeve 101 are concentrically arranged, and the mounting hole 106 is used to place the connecting sleeve 101. A groove 112 matching the length and width of the limit baffle 102 is provided at the rear end of the mounting hole 106, and the groove 112 is used to clamp the limit baffle 102 to prevent the connecting sleeve 101 from rotating in the mounting hole 106.

[0033] like Figure 5 , 6 As shown:

[0034] Slots 113 are symmetrically provided on both sides of the groove 112. The slots 113 are used to allow a certain amount of movable space for the reset plate 114. The slots 113 are used to limit the reset plate 114. A reset plate 114 is slidably provided in the slot 113.

The diameter of the round table 103 is from small to large. First, make the round table 103 straight. The end surface with a small diameter squeezes the limit baffle 102 from small to large until the limit baffle 102 is squeezed into the connecting sleeve 101, so that the limit baffle 102 is completely inserted into the groove 112, and the connecting sleeve 101 is limited and fixed to prevent the limit sleeve connected to the box body 100 from shaking in the mounting hole 106. When the box body 100 needs to be disassembled, the driving rod 104 is rotated to move the table 103 to the side close to the box body 100, and the limit baffle 102 loses the squeezing of the table 103. The reset plate 114 in the groove 112 returns the limit baffle 102 to the connecting sleeve 101 under the rebound of the reset spring 115, and then the connecting sleeve 101 is pulled out of the mounting hole 106.
