When the devices to be connected to the fiber optic distribution box are of various types and the models of the connected optical fibers are different, it is necessary to set up multiple different fiber optic distribution boxes for separate connections. The required installation space is large, which is not conducive to the installation of optical fibers in a smaller space. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following is combined with Figures 1 to 5 This application is described in further detail.

[0029] The present application embodiment discloses an expandable multi-cavity distribution box, referring to Figure 1 and Figure 2 , including a rectangular box 1, a rectangular mounting plate 2 and several mounting seats 3. The mounting plate 2 is fixedly installed in the box 1. The box 1 is placed vertically. The side wall of the box 1 is provided with an open mounting port 11. The box 1 is rotatably installed with a door body 13 for closing the mounting port 11 of the box 1.

[0030] Reference Figure 2 and Figure 5 Two vertical guide rails 12 are fixedly mounted on both sides of the mounting plate 2. Several slide rails 4 are provided between the two guide rails 12. The slide rails 4 are horizontal and the two ends of the slide rails 4 are slidably mounted on the guide rails 12. Several mounting seats 3 are slidably mounted on each slide rail 4. The mounting seats 3 are provided with connecting posts 31 for connecting to the optical fiber distribution frame.

[0031] Reference Figure 2 、 Figure 3 and Figure 5 For different types of optical fiber distribution frames, adaptive installation can be carried out through the sliding rails 4 and the sliding mounting seats 3, so that when welding optical fibers of multiple devices, the corresponding optical fiber distribution frames can be installed in the box 1 in advance, so that when connecting optical fibers of multiple different devices, only one box 1 is needed, which reduces the space occupied by the box 1. At the same time, later maintenance can be carried out in the same box 1, which is more convenient.

[0032] Reference Figure 2 、 Figure 3 and Figure 5The enclosure 1 is divided into several areas for installing fiber optic distribution frames. These areas are separated by partitions 8, which are provided with mounting holes 81 for securing pigtail cable connectors. In this embodiment, the enclosure 1 has two areas for installing fiber optic distribution frames. The partitions 8 allow different fiber optic distribution frames to be located in separate areas, preventing interference between the fibers of each frame. The pigtail cables are also connected separately through the partitions 8. This makes subsequent maintenance easier, with clear and concise information available, making it easier to identify the equipment corresponding to each area.

[0033] Reference Figure 2 、 Figure 3 and Figure 5 The mounting plate 2 for mounting a fiber optic distribution frame has an installation window 21 formed therethrough. The mounting seat 3 is located within the installation window 21. The mounting seat 3 is adjusted in the XY coordinate system within the installation window 21 by the cooperation between the slide rail 4 and the guide rail 12. This allows the mounting seat 3 to slide to the appropriate position for installation of various types of fiber optic distribution frames.

[0034] Reference Figure 2 、 Figure 3 and Figure 5 Both ends of the slide rail 4 are provided with a fixing mechanism 5 for fixing with the guide rail 12. The fixing mechanism 5 includes a first top block 51 slidably installed at the end of the slide rail 4 and a second top block 52 slidably sleeved on the first top block 51. A mounting cavity 511 is provided in the connecting part of the first top block 51 and the second top block 52. A tightening spring 53 is provided in the mounting cavity 511. A friction block 54 is fixed on the end surface of the second top block 52. The tightening spring 53 pushes the friction block 54 of the second top block 52 to press against the guide rail 12.

[0035] Reference Figure 2 、 Figure 3 and Figure 5 The slide rail 4 is further provided with a pushing mechanism 6, which is used to push the friction block 54 of the second top block 52 tightly against the friction block 54 and the guide rail 12 until the friction force between the friction block 54 and the guide rail 12 is increased to fix the slide rail 4.

[0036] When the pushing mechanism 6 does not push the second top block 52 to slide, the friction force generated by the friction block 54 that pushes the second top block 52 against the guide rail 12 is used to support the optical fiber distribution frame installed on the mounting seat 3. The slide rail 4 is pre-positioned by the second top block 52 and the friction block 54 in the initial state, so that when the optical fiber distribution frame is installed, the slide rail 4 is not easy to slip due to the action of installing the optical fiber distribution frame, which is beneficial to the installation and positioning of the optical fiber distribution frame, making the installation of the optical fiber distribution frame more convenient and quick.

[0037] Reference Figure 2 、 Figure 3 and Figure 5 The pushing mechanism 6 includes a push plate 61 slidably installed in the slide rail 4.

[0038] In this embodiment, the push block 61 is designed to be two pieces. The two push plates 61 are parallel to each other, and the two push plates 61 slide in opposite directions or toward each other along the width direction of the slide rail 4 .

[0039] Both ends of the push plate 61 are provided with inclined first guide surfaces 62 . The first top block 51 is provided with two guide blocks 55 corresponding to the two push plates 61 . The guide block 55 is provided with a second guide surface 56 that is in contact with the first guide surface 62 .

[0040] Reference Figure 2 、 Figure 3 and Figure 5 When the two push plates 61 slide back to back, the push plate 61 can push the guide block 55 toward the second top block 52 through the cooperation between the first guide surface 62 and the second guide surface 56, thereby pushing the first top block 51 to squeeze the pressing spring 53, and then pushing the second top block 52 and the friction block 54 to further press against the guide rail 12 through the pressing spring 53 until the slide rail 4 is fixed.

[0041] Reference Figure 3 、 Figure 4 and Figure 5 A plurality of pushing members 7 are provided between the two push plates 61. The pushing members 7 include a cylindrical slider 71 slidably installed between the two push plates 61. The side wall of the slider 71 is provided with two protrusions 72. The two protrusions 72 are both cylindrical and arranged opposite to each other. The end surface of the protrusion 72 away from the slider 71 is a hemispherical protrusion.

[0042] Under normal circumstances, the two push plates 61 are pressed against the side wall of the slider 71 under the reaction force of the pressing spring 53. When the two push plates 61 need to be pushed to move away from each other, it is only necessary to rotate the slider 71 to push the two push plates 61 to move away from each other through the protrusion 72 of the slider 71.

[0043] When the end of the protrusion 72 presses against the surface of the push plate 61, the push plate 61 pushes the guide block 55 and the first top block 51 until the pressing spring 53 is compressed. At this time, the second top block 52 and the friction block 54 press against the guide rail 12 under the push of the pressing spring 53 to generate a friction force that meets the requirement for fixing the slide rail 4.

[0044] Reference Figure 3 、 Figure 4 and Figure 5Since the opposite surface of the push plate 61 is relatively smooth, the pushing stability of the protrusion 72 on the push plate 61 is poor. Therefore, a plurality of positioning holes 63 are provided on the opposite surface of the two push plates 61 at intervals along the length direction of the push plate 61. The positioning holes 63 are embedded in the ends of the protrusions 72. When the slider 71 rotates to press against the push plate 61 through the protrusions 72, the ends of the protrusions 72 can be embedded in the positioning holes 63 to complete the fixation between the protrusions 72 and the push plate 61.

[0045] The spacing between the positioning holes 63 is the same as the difference between the mounting holes 81 of various fiber optic distribution frames. The length of the slider 71 is greater than the diameter of the positioning holes 63. The slider 71 is rotated until the protrusions 72 abut against the push plate 61. The slider 71 is then slid. When the end of one protrusion 72 is located at the positioning hole 63, the end of the other protrusion 72 remains in abutment with the surface of the push plate 61.

[0046] Through the above design, when the slider 71 passes through the positioning hole 63 during the sliding process, the positioning hole 63 will not interfere with the sliding of the slider 71 due to the support at both ends of the slider 71.

[0047] At the same time, during the sliding process of the slider 71, since the slider 71 is cylindrical, it may rotate during the sliding process, and then the two protrusions 72 may be aligned with the two positioning holes 63 and embedded in the positioning holes 63 at the same time, causing the sliding of the slider 71 to be blocked. Through the above design, there is always a protrusion 72 maintained in contact with the push plate 61, so that when the slider 71 slides, the sliding of the slider 71 will not be blocked due to the protrusion 72 being mistakenly embedded in the positioning hole 63.

[0048] The sliders 71 are rotatably mounted on the mounting base 3 in a one-to-one correspondence. The mounting base 3 can be positioned by the sliders 71 to facilitate the adaptation between the mounting base 3 and the distribution frame.

[0049] Reference Figure 2 、 Figure 3 and Figure 5 The slider 71 is coaxially fixedly connected to the connecting post 31. A nut is threadedly mounted on the connecting post 31, and the connecting post 31 secures the optical fiber distribution frame to the mounting base 3 via the nut. The cross-section of the positioning hole 63 is semicircular, and a blocking surface 64 is provided on one side of the positioning hole 63. The blocking surface 64 is located on the side of the connecting post 31 in the tightening direction of the nut, and is used to prevent the protrusion 72 from rotating out of the positioning hole 63.

[0050] Reference Figure 2 、 Figure 3 and Figure 5At the same time, because the push plate 61 is pressed against the slider 71, the slider 71 and the mounting base 3 connected to the slider 71 are not easy to move when no external force is applied, so that the position of the mounting base 3 is not easy to shift after the adjustment is completed, so that when the connecting column 31 and the slider 71 are rotated subsequently, the protrusion 72 can be aligned and embedded in the positioning hole 63.

[0051] After rotating the connecting post 31 until the protrusion 72 fits into the positioning hole 63, align the mounting hole 81 of the optical fiber distribution frame with the connecting post 31, then hang the optical fiber distribution frame on the connecting post 31, and finally tighten the nut to fix the optical fiber distribution frame on the mounting base 3.

[0052] Since the positioning hole 63 is provided with a blocking surface 64 on one side of the tightening direction of the nut, when the nut is tightened on the connecting column 31, the connecting column 31 and the slider 71 are in a stationary state, which facilitates the tightening of the nut and also makes it difficult for the protrusion 72 to be turned out of the positioning hole 63 during tightening.

[0053] The end of the connecting post 31 away from the slider 71 is provided with a rotating surface 311, and the rotating surface 311 is used to cooperate with a wrench to rotate the connecting post 31. When the connecting post 31 needs to be rotated or fixed, the connecting post 31 can be fixed more conveniently by a wrench.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
