[0024] Among them, one side of the outer wall of the sealing cover plate 2 is rotatably connected to one side of the outer wall of the housing 1, the input port 3 is installed at one end of the inner wall of the housing 1, and the distribution plate 4 is embedded at the other end of the inner wall of the housing 1

[0025] It should be noted that a clamping bin is provided at the bottom of the sealing cover plate 2 described in this embodiment, and when the sealing cover plate 2 is clamped on the housing 1, there is still a gap between the top of the input port 3 and the inner top of the clamping bin

[0026] It should be understood that a lock is installed on the outer wall of the housing 1, and a buckle matching the lock is installed on the outer wall of the sealing cover plate 2

[0027] The convenient maintenance mechanism 5 includes a support bottom plate 51, folding arms 52, a support top plate 53, a wire management component 54, and a pop-up component 55.

[0028] Among them, the support bottom plate 51 is symmetrically and fixedly connected to the inner bottom of the housing 1. There are two groups of folding arms 52. One ends of the two groups of folding arms 52 are symmetrically and fixedly connected to the top of the support bottom plate 51, and the support top plate 53 is fixedly connected to the other ends of the folding arms 52.

[0029] It should be noted that in this embodiment, the folding arms 52 described include a plurality of connecting arms, and the ends of the plurality of connecting arms are hinged to each other. Hinge seats are fixedly connected to the top of the support bottom plate 51 and the bottom of the support top plate 53, and the ends of the connecting arms are rotatably connected in the hinge seats.

[0030] The wire management component 54 is installed on the top of the support top plate 53, and the pop-up component 55 is installed at the bottom of the wire management component 54.

[0031] It should be noted that the wire management component 54 described in this embodiment can respectively limit multiple wire harnesses, ensuring more convenient subsequent maintenance. And through the pop-up component 55, under the action of the folding arms 52, the wire management component 54 can be conveniently popped out.

[0032] Specifically, after the wire splitter box for radio and television network transmission has been used for a long time, when the wire harness inside the splitter box needs to be maintained, since the support bottom plate 51 is symmetrically and fixedly connected to the inner bottom of the housing 1, there are two groups of folding arms 52, one ends of the two groups of folding arms 52 are symmetrically and fixedly connected to the top of the support bottom plate 51, the support top plate 53 is fixedly connected to the other ends of the folding arms 52, the wire management component 54 is installed on the top of the support top plate 53, and the pop-up component 55 is installed at the bottom of the wire management component 54. First, the sealing cover plate 2 is opened. During the opening process, the top of the wire management component 54 is not limited by the sealing cover plate 2. Subsequently, the wire management component 54 can be popped out under the action of the pop-up component 55 and located outside the splitter box, so that the wire harness can be placed outside the splitter box from the inside of the housing 1. Thus, it is more convenient for maintenance personnel to find the corresponding wire harness, effectively reducing the maintenance difficulty and improving the maintenance efficiency at the same time.

[0033] In an embodiment of the present invention, as Figures 1 - 4As shown in the figure, the wire management component 54 includes a limit bottom plate 541, a limit top plate 542, a contact head 543, a guide hole 544, and a fixed bottom plate 545. Among them, both ends of the fixed bottom plate 545 are fixedly connected to the top of the support top plate 53. The limit bottom plate 541 is fixedly connected to the top of the fixed bottom plate 545. The limit top plate 542 is clamped to the top of the limit bottom plate 541 by bolts. The guide holes 544 are equally spaced and opened on the top of the limit bottom plate 541 and the bottom of the limit top plate 542. The contact head 543 is fixedly connected to the top of the limit top plate 542.

[0034] Furthermore, as Figure 1 shown, the top of the contact head 543 is covered with a soft rubber pad, and the edge of the contact head 543 is arc-shaped.

[0035] It should be noted that the guide holes 544 opened on the top of the limit bottom plate 541 and the bottom of the limit top plate 542 described in this embodiment correspond to each other one by one, and a damping pad is installed on the inner wall of the guide hole 544.

[0036] Specifically, in order to make the later maintenance of the wire harness more convenient, since both ends of the fixed bottom plate 545 are fixedly connected to the top of the support top plate 53, the limit bottom plate 541 is fixedly connected to the top of the fixed bottom plate 545, the limit top plate 542 is clamped to the top of the limit bottom plate 541 by bolts, the guide holes 544 are equally spaced and opened on the top of the limit bottom plate 541 and the bottom of the limit top plate 542, and the contact head 543 is fixedly connected to the top of the limit top plate 542. Thus, multiple wire harnesses can be respectively placed inside different guide holes 544. When maintenance is required later, by screwing the bolts, the limit top plate 542 can be opened, so as to facilitate taking out the corresponding wire harness. At the same time, when the sealing cover plate 2 is clamped on the housing 1, the contact head 543 abuts against the sealing cover plate 2.

[0037] In an embodiment of the present utility model, as Figures 1 - 4 shown, the pop-up component 55 includes a support sleeve 551, a support rod 552, and a support spring 553. Among them, the support sleeves 551 are symmetrically and fixedly connected to the bottom of the fixed bottom plate 545. One end of the support spring 553 is fixedly connected to the inner top of the support sleeve 551. One end of the support rod 552 slidably penetrates through the end of the support sleeve 551 and is fixedly connected to the other end of the support spring 553. The other end of the support rod 552 is fixedly connected to the inner bottom of the housing 1.

[0038] Specifically, in order to further improve the maintenance efficiency, since the support sleeve 551 is symmetrically and fixedly connected to the bottom of the fixed base plate 545, one end of the support spring 553 is fixedly connected to the inner top of the support sleeve 551, one end of the support rod 552 slidably penetrates through the end of the support sleeve 551 and is fixedly connected to the other end of the support spring 553, and the other end of the support rod 552 is fixedly connected to the inner bottom of the housing 1. Thus, when the sealing cover plate 2 is opened, since the abutting head 543 is released from the restraint of the sealing cover plate 2, under the action of the support spring 553, the fixed base plate 545 can be quickly lifted under the action of the folding arm 52. Thereby, the limit base plate 541 and the limit top plate 542 can be placed outside the distribution box, so that the maintenance space is increased and the maintenance efficiency is effectively improved.

[0039] A plurality of distribution holes 41 are arranged in an array on the distribution plate 4, and damping pads are fixedly connected to the inner walls of the distribution holes 41 in a circumferential array. When the wire harness passes through the distribution holes 41 and exits, under the action of the damping pads, a certain length of the wire harness can be reserved inside the housing 1, so as to ensure that when the fixed base plate 545 pops out, the wire harness has a certain length of pulling space to avoid damage to the wire harness.

[0040] In summary, for the network cable distribution box for radio and television network transmission according to the embodiment of the present invention, first, the sealing cover plate 2 is opened. During the opening process, the top of the wire management assembly 54 is not limited by the sealing cover plate 2. Subsequently, the wire management assembly 54 can pop out under the action of the popping assembly 55 and be located outside the distribution box, so that the wire harness can be placed outside the distribution box from the inside of the housing 1. Thereby, it is more convenient for maintenance personnel to find the corresponding wire harness, effectively reducing the maintenance difficulty and improving the maintenance efficiency at the same time.
