the sliding assembly 9 comprises slidingplates 91 fixedly connected to the bottom of the distributormain body 1, the cross-sectional shapes of the two slidingplates 91 are in a convex shape, slidingrails 92 are sleeved outside the two slidingplates 91 in a sliding mode, mountingplates 93 with screw holes are symmetrically arranged on the sides, away from each other, of the two slidingrails 92 respectively, the two mountingplates 93 are designed to be integrated with the slidingrails 92 respectively, slidingblocks 94 are fixedly connected to the bottoms of the two slidingblocks 94, and slidinggrooves 95 matched with the slidingblocks 94 for use are formed in the bottoms of the two slidingrails 92;

one side of thedistributor body 1 is provided with an automatic wirelength adjusting mechanism 10 matched with the sliding assembly 9;

the automatic wirelength adjusting mechanism 10 comprises a T-shapedrod 101 fixedly connected to one end of theworm 88, the T-shapedrod 101 consists of a round rod and a disc with a convex block, around pipe 102 is sleeved on the outer portion of the T-shapedrod 101 in a sliding mode, aguide groove 103 connected with the T-shapedrod 101 in a sliding mode along the radial direction is formed in the inner portion of theround pipe 102, asecond spring 104 is movably sleeved on the outer portion of the T-shapedrod 101 in a sleeved mode, thesecond spring 104 is arranged in theround pipe 102, apull ring 105 is arranged on one side of theround pipe 102, thepull ring 105 and theround pipe 102 are designed in an integrated mode, a secondtoothed ring 106 is fixedly sleeved on the outer portion of theround pipe 102, and arack 107 meshed with the secondtoothed ring 106 is fixedly connected to the top of one slidingrail 92;

thesnap ring 85 is made of a plastic material with certain elasticity;

the length of eachsecond gear 86 is less than or equal to that of the wire take-up rod 81 (thesecond gears 86 are meshed with thefirst gear ring 84, and can limit the slidingsupport 83 from rotating around thebidirectional screw rod 82, so that the slidingsupport 83 can only linearly displace back and forth along the bidirectional screw rod 82), the square rods 71 and thewire leading plate 6 are arranged in parallel, and the square rods 71 are arranged below the plurality of wire inserting holes 3;

when the plug terminal is plugged, the plug terminal sequentially passes through the wire outlet groove 4, the first toothed ring 84 and the groove on the lead plate 6, then the limiting clamp 73 is opened to insert the plug terminal into the wire inserting hole 3, the T-shaped plate (78) is loosened to clamp the plug terminal, the connecting cable at the tail end of the plug terminal is clamped into the snap ring 85 on the inner side of the first toothed ring 84 (the connecting cable can slide in the snap ring 85), it is confirmed that all the connecting cables are completely placed into the wire outlet groove 4, finally the sealing cover 5 is closed, the pull ring 105 pulls the circular tube 102, the circular tube 102 drives the second toothed ring 106 to move radially, the circular tube 102 slides outside the T-shaped rod 101 and extrudes the second spring 104, so that the second toothed ring 106 moves to a position where the second toothed ring 106 is not meshed with the rack 107, at this time, the circular tube 102 can be rotated by the pull ring 105, the T-shaped rotating rod 101 is driven to rotate synchronously by the circular tube 102, so that the T-shaped rod 101 drives the worm gears 86 to rotate synchronously, the second toothed ring 84 is wound around the first toothed ring 81, and the connecting cable is connected to the first toothed ring 81;

it should be noted that, since thesecond gear 106 is moved out of engagement with therack 107 by pulling thepull ring 105 outward, thedispenser body 1 does not slide back and forth relative to theslide rail 92 when the connecting cable is wound around the take-upshaft 81 by rotating thepull ring 105.

When thesecond gear 86 rotates, thebelt 87 is driven to synchronously rotate, so that thebidirectional screw 82 is driven to rotate, thebidirectional screw 82 drives the slidingbracket 83 to slide back and forth along thebidirectional screw 82, and the connecting cable is uniformly wound outside the whole cable take-uprod 81;

when the multifunctional audio and video distributor is installed, the multifunctional audio and video distributor is placed at a proper position in the cabinet, then a plurality of bolts penetrate through theinstallation plate 93 and the screw holes in the cabinet, and the bolts are screwed tightly, so that the multifunctional audio and video distributor can be installed;

when the multifunctional audio and video distributor needs to be overhauled, only the distributormain body 1 needs to be pulled, the two slidingplates 91 can be driven to slide in the slidingrails 92 through the distributormain body 1, the slidingplates 91 drive the slidingblocks 94 to synchronously slide in the slidinggrooves 95, and therefore the distributormain body 1 is pulled out of a cabinet for overhauling;

in the process of pulling out the distributor main body 1, the distributor main body 1 drives the circular tube 102 and the second toothed ring 106 to synchronously move, and drives the circular tube 102 to move and rotate at the same time through the meshing action between the second toothed ring 106 and the rack 107, so that the circular tube 102 drives the T-shaped rod 101 to synchronously rotate through the guide groove 103 on the inner side, so that the T-shaped rod 101 drives the worm 88 to synchronously rotate, and thus the first toothed ring 84 is driven to reversely rotate and reciprocate outside the wire take-up rod 81 through the cooperation between the structures, and when the distributor main body 1 is pulled out, the connecting cable wound outside the wire take-up rod 81 is released (namely, when maintenance is not needed, the redundant length of the connecting cable is all wound on the wire take-up rod 81, when maintenance is needed, as long as the distributor main body 1 is pulled out, the first toothed ring 84 is automatically driven to rotate and pay off in the process that the second toothed ring 106 advances along the rack 107, so as to avoid the connecting cable being short in length and unable to pull out the distributor main body 1);

when the maintenance of thedistributor body 1 is finished, thedistributor body 1 is directly pushed into the cabinet, at this time, the secondtoothed ring 106 reversely rotates in the pushing-in process of thedistributor body 1 through the meshing action between the second toothed ring and therack 107, and the connecting cable released when thedistributor body 1 is pulled out is wound outside the take-uprod 81 again through the matching between the structures;

according to the invention, the take-upmechanism 8 is arranged, so that the connecting cable of the plug terminal can be wound, and the phenomena that the connecting cable is exposed outside, disordered and inconvenient to overhaul are avoided; by arranging the sliding assembly 9, the multifunctional audio and video distributor can be pulled out of the cabinet body under the condition that the multifunctional audio and video distributor is not detached, so that the overhauling convenience of the multifunctional audio and video distributor can be effectively improved; through being equipped with line length automatically regulatedmechanism 10, can use sliding assembly 9 to pull out distributormain part 1 when overhauing, realize the automatically regulated of connecting cable length, release the connecting cable when pulling out, when overhauing the end and restoreing distributormain part 1, the connecting cable rolling of will releasing, the phenomenon that connecting cable winding is difficult to the clearance appears when both can avoiding overhauing, to the arrangement effect of connecting cable when guaranteeing distributormain part 1 to overhaul, can prevent again to appear being difficult to the phenomenon of pulling out because of the connecting cable restriction when pulling out distributormain part 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
