Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and more particularly to a rotary distribution box. Background Art

[0002] Chinese Utility Model Patent with Publication No. CN202676963U discloses a rotary distribution box, which includes a bottom box and a top cover connected to the bottom box. The top cover is rotatably connected to the bottom box. A rotary drawer is rotatably connected to the bottom surface inside the bottom box, and a rotating shaft for rotatably connecting the rotary drawer is provided at the front corner of the bottom box.

[0003] By installing connection parts such as fiber optic distribution frames for connecting optical fibers on the rotary drawer, the rotary drawer can be rotated during subsequent maintenance to turn out components such as fiber optic distribution frames from the bottom box, facilitating detection and maintenance.

[0004] However, in the above solution, the rotary drawer is only supported by the rotating shaft during rotation. When the volume of the rotary drawer is small, relatively stable rotational support can be achieved only by the rotating shaft, and the connection between the rotating shaft and the rotary drawer is not easily deformed or damaged. However, when the volume of the rotary drawer is large, if it is still only rotationally supported by the rotating shaft and the rotational support needs to be relatively stable, the rotating shaft needs to be designed thicker, which will result in a large occupied space of the rotating shaft in the bottom box and may interfere with the coiling of optical fibers on the connection components of the rotary drawer. Summary of the Invention

[0005] In order to solve the problem that when the rotary drawer is supported only by the rotating shaft and the volume of the rotary drawer is large, the rotating shaft may need to be designed thicker, which may interfere with the coiling of optical fibers on the connection components of the rotary drawer, this application provides a rotary distribution box.

[0006] The rotary distribution box provided by this application adopts the following technical solutions: A rotary distribution box, comprising: A box body, used as a protective shell, with one side wall of the box body being open; A side cover, used to close the open side wall of the box body; A mounting plate, rotatably installed on the box body through a rotating shaft, used for installing optical fiber connection components. When the side cover is opened, the part for installing components can be rotated from inside the box body through the open side wall of the box body to outside the box; A limiting rod, provided on the box body; The mounting plate is provided with an arc-shaped hole running through it. The arc-shaped hole is coaxial with the rotating shaft at the rotational connection between the mounting plate and the box body. The limiting rod slides through the arc-shaped hole. When the mounting plate is inside the box, the side wall of the limiting rod abuts against one end of the arc-shaped hole. When the mounting plate rotates to a specified angle outside the box, the side wall of the limiting rod abuts against the other end of the arc-shaped hole.

[0007] Through the above technical solution, when the mounting plate rotates, the cooperation between the limiting rod and the arc-shaped hole limits and stabilizes the mounting plate. Compared with the single-point support of the rotating shaft for the mounting plate, the mounting plate is supported at two points through the mutual cooperation between the limiting rod and the rotating shaft, and the overall support is more stable. The connection between the rotating shaft and the mounting plate is not easily deformed. At the same time, the rotation stroke of the mounting plate is limited by the arc-shaped hole, so that the mounting plate will not break the welded optical fiber due to excessive rotation, or the components on the mounting plate will not vibrate when the mounting plate rebounds and hits the side wall of the box body.

[0008] Optionally, the mounting plate is provided with a baffle, the baffle is arranged in a ring along the contour of the arc-shaped hole, the baffle fits against the side wall of the limiting rod, and buffer layers are arranged at both ends of the baffle located at the arc-shaped hole.

[0012] Optionally, fixing grooves are provided on the limiting plates at both ends of the limiting groove, friction layers are provided on the side walls of the fixing grooves, fixing blocks are provided on the mounting plate at both ends of the arc-shaped side of the mounting plate, friction layers are also provided on the side walls of the fixing blocks, the fixing blocks and the fixing grooves are slidably matched, and when the mounting plate rotates to any end of the arc-shaped groove and abuts against the limiting rod, the fixing block on the corresponding side is inserted into the fixing groove in a matching manner, and the friction layer of the fixing block presses against the friction layer of the fixing groove.

[0013] Optionally, a positioning block is slidably mounted on the limiting plate, the positioning block is slidably inserted into the fixing groove, the friction layer of the fixing groove is arranged on the side wall of the positioning block, a pressing rod is rotatably mounted on the limiting plate, and a pressing spring is arranged on the limiting plate. When the fixing block is inserted into the fixing groove in a matching manner, the pressing spring pushes the pressing rod to press against the positioning block, and further pushes the positioning block to press against the fixing block.

[0014] Optionally, a gap is provided between the lower side wall of the limiting groove and the mounting plate.

[0015] Optionally, reinforcing strips are provided on the remaining sides of the mounting plate except for its arc-shaped side.

[0016] Optionally, chamfers are provided on the opposite sides of the two fixing blocks, and the chamfers are used to guide the fixing blocks to push the positioning blocks to move in the reverse direction.

[0017] In summary, when the mounting plate of the present application rotates, the cooperation between the limiting rod and the arc-shaped hole is used to limit and stabilize the mounting plate. Compared with the single-point support of the rotating shaft for the mounting plate, the mounting plate is supported at two points through the mutual cooperation between the limiting rod and the rotating shaft, and the overall support is more stable. The connection between the rotating shaft and the mounting plate is not prone to deformation. At the same time, the rotation stroke of the mounting plate is limited by the arc-shaped hole, so that the mounting plate will not pull the welded optical fiber off due to excessive rotation, or the mounting plate will not hit the side wall of the box body when reset, causing vibration of the components on the mounting plate.

Detailed implementation mode

[0028] The following further elaborates on this application in conjunction with the attached drawings Figure 1-8 and provides a more detailed description.

[0029] An embodiment of this application discloses a rotary wiring box. Refer to Figure 1 , Figure 2 and Figure 3 , which includes a box body 1 in the shape of a cuboid. Define the two side walls with the largest area of the box body 1 as the bottom wall and the top wall of the box body 1. The top wall of the box body 1 is open, and a top cover 12 is rotatably installed at the top wall of the box body 1. One of the side walls of the box body 1 is also open, and a side cover 11 is rotatably installed on the side wall of the box body 1. The top cover 12 is used to close the opening of the top wall of the box body 1, and the side cover 11 is used to close the opening of the side wall of the box body 1. A buckle is also provided between the top cover 12 and the side cover 11 for mutual connection and fixation.

[0030] Refer to Figure 2 , Figure 3 and Figure 5 , a mounting plate 2 is rotatably installed on the bottom wall of the box body 1 through a rotating shaft 13, and the rotating shaft 13 is vertical. The mounting plate 2 is used to install components for optical fiber connection. One side edge of the mounting plate 2 away from the rotating shaft 13 is arc-shaped, and the arc edge of the mounting plate 2 is coaxial with the rotating shaft 13. When the side cover 11 is opened, the part of the mounting plate 2 for installing connection components can be rotated out of the opening of the side wall of the box body 1 to the outside. The arc-shaped side enables the mounting plate 2 to be rotated out of the box body 1 while ensuring a relatively large installation area.

[0031] Refer to Figure 2 , Figure 3 and Figure 5 , an arc-shaped hole is formed through the mounting plate 2 near the rotating shaft 13, and the arc-shaped hole is coaxial with the rotating shaft 13. Baffles 22 are provided on both the upper and lower plate surfaces of the mounting plate 2. The baffles 22 are arranged along the contour of the arc-shaped hole, and the inner wall of the baffle 22 is flush with the hole wall of the arc-shaped hole.

[0032] Refer to Figure 2 , Figure 3 and Figure 5 , a limiting rod 14 is fixedly installed on the bottom wall of the box body 1. The limiting rod 14 is vertical, and the upper end of the limiting rod 14 slides through the arc-shaped hole, and the side wall of the limiting rod 14 abuts against the inner wall of the baffle 22.

[0033] Refer to Figure 2 , Figure 3 and Figure 5 , during the rotation of the mounting plate 2, through the cooperation between the limiting rod 14 and the arc-shaped hole, the mounting plate 2 has two-point limiting of the rotating shaft 13 and the limiting rod 14 during the rotation process, making the rotation process of the mounting plate 2 more stable.

[0034] Refer to Figure 2 , Figure 3 and Figure 5 , when the part of the mounting plate 2 for installing and connecting components is completely outside, the side wall of the limiting rod 14 fits and presses against one end of the arc-shaped hole. When the mounting plate 2 is completely retracted, the side wall of the limiting rod 14 fits and presses against the other end of the arc-shaped hole.

[0035] Refer to Figure 2 , Figure 3 and Figure 5 , through the limiting of the limiting rod 14 by the arc-shaped hole, when the mounting plate 2 rotates out of the box body 1, it is not easy to rotate excessively and break the optical fiber, or when the mounting plate 2 rotates back into the box body 1, it will collide with the inner wall of the box body 1, resulting in damage to the box body 1 and the mounting plate 2, as well as loosening of the components on the mounting plate 2.

[0036] Refer to Figure 2 , Figure 3 and Figure 5 , at the same time, the baffle 22 is designed to make the limiting of the mounting plate 2 by the limiting rod 14 more stable, and since the arc-shaped hole 21 is provided, the strength of the rotating connection between the mounting plate 2 and the box body 1 is reduced. Therefore, by designing the baffle 22, it is also used to reinforce the rotating connection between the mounting plate 2 and the box body 1, making the rotating connection between the mounting plate 2 and the box body 1 less likely to deform.

[0037] Refer to Figure 2 , Figure 3 and Figure 5 , buffer layers 23 are fixedly installed at both ends of the arc-shaped hole 21 where the baffle 22 is located to buffer the impact vibration between the limiting rod 14 and the baffle 22.

[0038] Refer to Figure 4 and Figure 6 , a plurality of support blocks 15 are integrally provided on the bottom wall of the box body 1, a friction layer 3 made of rubber is fixedly provided on the top of the support blocks 15, the friction layer 3 fits and presses against the lower plate surface of the mounting plate 2, the support blocks 15 are arranged along the rotation direction of the mounting plate 2, and the mounting plate 2 is supported by the support blocks 15, further improving the stability of the mounting plate 2 during the rotation process and making the rotating connection of the mounting plate 2 less likely to deform.

[0039] Moreover, due to the existence of the friction layer 3, the mounting plate 2 will be interfered by the frictional resistance of the friction layer 3 during rotation, making it difficult for the mounting plate 2 to rotate too fast. As a result, when the mounting plate 2 rotates out, if the components on it are loose, they will not directly fall off, which may cause the optical fiber to be pulled off.

[0040] Refer to Figure 5 , the mounting plate 2 is rectangular. On the other three sides of the mounting plate 2 except its arc edge, reinforcing strips 5 are bent upward to increase the strength of the mounting plate 2. On the top wall of the reinforcing strip 5 on the side of the mounting plate 2 facing the opening of the side wall of the box body 1, a reinforcing plate 51 is integrally bent. The upper end of the rotating shaft 13 is rotatably connected to the reinforcing plate 51.

[0041] Through the cooperation between the rotating shaft 13 and the reinforcing plate 51, the rotational stability of the mounting plate 2 is further improved.

[0042] Refer to Figure 6 , Figure 7 and Figure 8 , the box body 1 is fixedly provided with a mounting rod 4. A horizontal limiting plate 41 is fixedly installed on the mounting rod 4. A limiting groove 411 is opened on the side wall of the limiting plate 41 facing the mounting plate 2. The arc edge of the mounting plate 2 is located in the limiting groove 411 and fits with the upper side wall of the limiting groove 411. Through the limitation of the limiting groove 411, it is more difficult for the mounting plate 2 to jump upward during rotation.

[0043] Through the cooperation between the limiting groove 411 and the support block 15, the mounting plate 2 is more stable during rotation.

[0044] Refer to Figure 6 , Figure 7 and Figure 8 , fixing grooves 412 are provided at both ends of the limiting groove 411 on the limiting plate 41, and the fixing grooves 412 communicate with the limiting groove 411. Two mounting holes are opened on the top wall of the limiting plate 41, and the mounting holes communicate with the fixing grooves 412. Positioning blocks 42 are slidably installed in the mounting holes. The two positioning blocks 42 are fixedly connected by a connecting rod 45. The connecting rod 45 fits and presses against the top wall of the limiting plate 41. The lower end of the positioning block 42 extends into the fixing groove 412, and a friction layer 3 made of rubber is also fixedly installed on the lower end surface of the positioning block 42.

[0045] Refer to Figure 6 , Figure 7 and Figure 8, a pressing rod 43 is rotatably installed on the top wall of the limiting plate 41. One end of the pressing rod 43 extends to the pressing connecting rod 45. A pressing spring 44 is fixedly installed on the top wall of the limiting plate 41. The upper end of the pressing spring 44 presses against the pressing rod 43, thereby pushing one end of the pressing rod 43 against the connecting rod 45. Taking the rotation connection of the pressing rod 43 as the dividing line, the length of the end of the pressing rod 43 away from the connecting rod 45 is greater than the length of the end of the pressing rod 43 pressing against the connecting rod 45. Thus, it is relatively convenient to press down the end of the pressing rod 43 away from the connecting rod 45 through the lever principle to separate the pressing rod 43 from the connecting rod 45.

[0046] Refer to Figure 5 , fixing blocks 24 are fixedly provided on the mounting plate 2 at both ends of the arc-shaped side of the mounting plate 2. A friction layer 3 made of rubber is also fixedly provided on the top wall of the fixing block 24. The fixing block 24 is in sliding fit with the fixing groove 412.

[0047] Refer to Figure 6 , Figure 7 and Figure 8 , when the mounting plate 2 rotates to any end of the arc-shaped groove and presses against the limiting rod 14, the corresponding fixing block 24 is inserted into the fixing groove 412 in a matching manner. Chamfers 241 are provided on the opposite sides of the two fixing blocks 24. When the fixing block 24 is inserted into the fixing groove 412, the fixing block 24 pushes the positioning block 42 to move upward through the chamfer 241.

[0048] At this time, the resistance for the operator to rotate the mounting plate 2 increases. After the operator receives the feedback information of the increased resistance, it can be known that the pressing rod 43 needs to be pressed down to facilitate the insertion of the fixing block 24 into the fixing groove 412. Then, the pressing rod 43 is released, so that the pressing rod 43 presses against the positioning block 42 under the push of the pressing spring 44, and the friction layers 3 of the fixing block 24 and the positioning block 42 are pressed against each other to fix the mounting plate 2.

[0049] And compared with fixing the mounting plate 2 through a buckle structure, if components are to be installed on the mounting plate 2 to make the mounting plate 2 not shake, the buckle structure requires higher precision. However, the above structure of the present application has lower requirements for the installation precision of the friction layer 3, thereby making the overall manufacturing and assembly difficulty lower, and further making the overall production efficiency higher, and the subsequent use stability is also higher.

[0050] Refer to Figure 6 and Figure 7 , at the same time, there is a gap between the mounting plate 2 and the lower side wall of the limiting groove 411. When the positioning block 42 presses against the fixing block 24, it will also push the mounting plate 2 against the support block 15, further strengthening the stability after fixation.

[0051] When it is necessary to rotate the mounting plate 2 out of the box body 1, first press the end of the abutting rod 43 away from the connecting rod 45, so that after the positioning block 42 and the fixing block 24 change from abutting against each other to abutting against each other, rotate the mounting plate 2 out of the box body 1. When rotating until the fixing block 24 leaves the fixing groove 412, the abutting rod 43 can be released.

[0052] When the mounting plate 2 rotates until the limiting rod 14 abuts against the end of the arc-shaped hole 21, another fixing block 24 is inserted into the fixing groove 412, and the overall fixing of the mounting plate 2 can be completed. On the contrary, when the above operations are repeated and then the mounting plate 2 is reset so that the side wall of the limiting rod 14 abuts against the other end of the arc-shaped hole 21, the fixing block 24 is inserted into the fixing groove 412 again, and the fixing of the mounting plate 2 can be completed, making the overall rotation and fixing of the mounting plate 2 more convenient.

[0053] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
