[0002] Communication network cable distribution equipment, commonly known as communication cable distribution box or distribution box, is a device used to realize the branching and distribution of cable lines in communication networks. It can divert signals from the main cable so that the signals can enter different terminal devices or branch lines respectively. At the same time, it can also merge the signals of multiple branch lines to form one or more signals to enter the next level equipment or trunk cable.

[0003] However, existing communication network cable distribution equipment has problems and shortcomings during use. During long-term use, the cable connection will become loose under the action of external force, or the cable connection will become loose without being tightly connected, which will lead to poor contact and affect use. Loose cable connections will lead to poor contact, resulting in poor current transmission, affecting the normal operation of the cable distribution equipment. Loose connections will increase resistance and generate excessive heat. As time goes by, heat continues to accumulate and the temperature gradually rises, which may damage the insulation layer of the cable and generate electric sparks or discharge. If the ignition point of the objects around the cable connection is reached, a fire may occur. Loose cable connections require frequent tightening and repair, which increases maintenance costs. Due to damage caused by looseness, damaged cables or equipment may need to be replaced, further increasing costs. Summary of the invention

[0030] In addition, a plurality of filter screens 201 are fixedly connected inside the bottom plate 200 , and a circular hole 202 is opened inside the bottom plate 200 .

[0031] Specifically, the tightening mechanism 300 includes an air pump 301, the lower end of the air pump 301 is fixedly connected to the bottom plate 200, the output end of the air pump 301 is fixedly connected to an air inlet pipe 302, the inside of the air inlet pipe 302 is fixedly connected to a one-way valve 303, one end of the air inlet pipe 302 is fixedly connected to an air bag 304, the top of the air bag 304 is fixedly connected to the cable connector 101, and the surface of the air bag 304 is fixedly connected to an air core 305; the air pump 301 is started at an interval by the controller, and the air pump 301 will produce gas flowing out from the air inlet pipe 302. A one-way valve 303 is arranged on the air inlet pipe 302 so that air can only be input into the airbag 304. When the air pressure inside the airbag 304 reaches a certain value, it will flow out through the pressure relief valve 402 arranged on the air outlet pipe 401. The airbag 304 is annularly provided with a conductor on the inner surface connected to the cable connector 101. When the airbag 304 expands, it will wrap the cable inside it, so that the conductor inside the airbag 304 fits tightly with the end of the cable, and at the same time can improve the cable fixing effect.

[0032] Furthermore, the cleaning mechanism 400 includes an air outlet pipe 401, one end of which is fixedly connected to the airbag 304 and communicates with the interior thereof, a pressure relief valve 402 is fixedly connected to the interior of the air outlet pipe 401, the upper end of the air outlet pipe 401 is fixedly connected to a box body 403, a first baffle 404 is fixedly connected to the inner surface of the box body 403, a tension spring 407 is fixedly connected to the upper end of the first baffle 404, an opening 4041 is opened inside the first baffle 404, and a second baffle 405 is also fixedly connected to the inner surface of the box body 403.

The high-pressure gas will be discharged from the hollow groove 4081 and will enter the interior of the nozzle 411 through the hose 410. The high-pressure gas ejected downward from the nozzle 411 will clean the dust attached to the bottom of the filter 201. When the high-pressure gas in the bellows 406 is almost exhausted, the internal pressure will decrease. When the internal air pressure of the bellows 406 is lower than the tension spring 407, the bellows 406 will reset. The bellows 406 will reset and move downward, which will drive the lower end of the first sliding block 408 to move downward. The lower end of the first sliding block 408 will move downward, which will drive the hollow groove 4081 away from the opening 4041 inside the bellows 406. The first sliding block 40 The downward movement of the lower end of the device 8 will also drive the suction cup 409 to move downward. The downward movement of the suction cup 409 will be away from the lower end surface of the second partition 405 and disconnect the adsorption. After the high-pressure gas accumulates pressure inside the box 403, it will be ejected to clean the dust attached to the bottom of the filter 201, so as to avoid the filter 201 at the bottom of the device being blocked and affecting the ventilation of the device. The heat dissipation performance of the device will be greatly reduced, and the internal temperature may rise rapidly. The high temperature environment may cause the performance of the device to decline, or even cause malfunctions. In serious cases, it may cause safety problems such as device damage or fire. ;

[0033] It should be noted that the fixing mechanism 500 includes a first ring 501, the upper end of the first ring 501 is fixedly connected to the bottom end of the airbag 304, the surface of the first ring 501 is fixedly connected to a second sliding block 502, the outer portion of the second sliding block 502 is sleeved with a sleeve 503 and elastically connected to the sleeve through a spring, the lower end of the second sliding block 502 is fixedly connected to a second ring 504, the lower end of the second ring 504 is fixedly connected to a rubber ring 505, and the lower end of the rubber ring 505 is in contact with the bottom plate 200; the airbag 304 will expand after being inflated, and since the top end of the airbag 304 is fixedly connected to the cable connector 101, when the airbag 304 expands, it will drive the first ring 501 to move downward, and the downward movement of the first ring 501 will drive the second sliding block 502 to move downward The second sliding block 502 moves downward to compress the spring inside the sleeve 503 to move downward, and the second sliding block 502 moves downward to drive the second ring 504 to move downward, and the second ring 504 moves downward to squeeze the rubber ring 505 downward, and the rubber ring 505 is squeezed and deformed to block the gap between the cable and the circular hole 202. When the airbag 304 expands, it drives the second ring 504 to move downward, and the second ring 504 moves downward to squeeze the rubber ring 505 downward, and the rubber ring 505 is squeezed and deformed to block the gap between the cable and the circular hole 202. Blocking the gap between the cable and the circular hole 202 can prevent external dust from entering the device without being filtered. Secondly, the rubber ring 505 is squeezed to further fix the cable.

[0034] It is worth mentioning that a bolt 601 is meshed inside the nut 600, and the outer surface of the nut 600 is fixedly connected to the airbag 304. One end of the bolt 601 is fixedly connected to a rubber block 602. A nut 600 is provided on the surface of the airbag 304. Before the device is used, the bolt 601 is screwed into the nut 600, and the rubber block 602 at the front end of the bolt 601 will tightly fit and press the conductor on the inner surface of the airbag 304 and the cable.

[0035] Working principle: When the present invention is in use, the cable is inserted from the lower end of the bottom plate 200 through the circular hole 202, and the cable enters the interior of the airbag 304 through the circular hole 202.

[0036] At this time, the controller starts the inflation pump 301 at an interval, and the inflation pump 301 will generate gas flowing out from the air inlet pipe 302. A one-way valve 303 is provided on the air inlet pipe 302 so that air can only be input into the airbag 304. When the air pressure inside the airbag 304 reaches a certain value, it will flow out through the pressure relief valve 402 provided on the air outlet pipe 401. The airbag 304 is annularly provided with a conductor on the inner surface connected to the cable connector 101. When the airbag 304 expands, it will wrap the cable inside it, so that the conductor in the airbag 304 fits tightly with the end of the cable, and at the same time, it can also improve the cable fixing effect. Through the set structure, the inflation pump 301 can be started at an interval to tighten the cable and the cable connector 101.

[0037] The gas flowing out of the airbag 304 will enter the interior of the box 403 through the air outlet pipe 401, and the gas will enter the interior of the bellows 406 through the opening 4041 in the box 403. When a large amount of gas enters the interior of the bellows 406, it will expand. The expansion of the bellows 406 will stretch the tension spring 407. When the bellows 406 expands and moves upward to a certain extent, it will contact the upper end of the first sliding block 408 and drive it to move upward. The upward movement of the upper end of the first sliding block 408 will drive the suction cup 409 to move upward, and the suction cup 409 will move upward.

It should be noted that the elastic force of the tension spring 407 is greater than the suction force of the suction cup 409. The first sliding block 408 is C-shaped. The upward movement of the first sliding block 408 will drive the lower end to move upward. The upward movement of the lower end of the first sliding block 408 will drive the hollow groove 4081 to enter the interior of the bellows 406. At this time, the high-pressure gas inside the bellows 406 will be discharged from the hollow groove 4081. The high-pressure gas will be discharged from the hollow groove 4081 and will enter the interior of the nozzle 411 through the hose 410. The high-pressure gas ejected downward from the nozzle 411 will clean the dust attached to the bottom of the filter 201. When the high-pressure gas in the bellows 406 is almost exhausted, the internal pressure will decrease. When the internal air pressure of the bellows 406 is lower than the tension spring 407, the bellows 406 will reset. The bellows 406 will reset and move downward, which will drive the lower end of the first sliding block 408 to move downward. The lower end of the first sliding block 408 will move downward, which will drive the hollow groove 4081 away from the opening 4041 inside the bellows 406. The first sliding block 40 The downward movement of the lower end of 8 will also drive the suction cup 409 to move downward. The downward movement of the suction cup 409 will move away from the lower end surface of the second partition 405 and disconnect the adsorption. After the high-pressure gas accumulates pressure inside the box 403, it will be ejected to clean the dust attached to the bottom of the filter 201, so as to avoid the filter 201 at the bottom of the equipment being blocked and affecting the ventilation of the equipment. The heat dissipation performance of the equipment will be greatly reduced, and the internal temperature may rise rapidly. The high temperature environment may cause the performance of the equipment to decline, or even cause malfunctions. In severe cases, it may cause safety problems such as equipment damage or fire.

[0038] After the airbag 304 is inflated, it will expand. Since the top of the airbag 304 is fixedly connected to the cable connector 101, when the airbag 304 expands, it will drive the first ring 501 to move downward. The downward movement of the first ring 501 will drive the second sliding block 502 to move downward. The downward movement of the second sliding block 502 will compress the spring inside the sleeve 503 to move downward. The downward movement of the second sliding block 502 will drive the second ring 504 to move downward. The downward movement of the second ring 504 will squeeze the rubber ring 505 downward. The rubber ring 505 will be deformed by being squeezed to block the gap between the cable and the circular hole 202. When the airbag 304 expands, it will drive the second ring 504 to move downward. The downward movement of the second ring 504 will squeeze the rubber ring 505 downward. The rubber ring 505 will be deformed by being squeezed to block the gap between the cable and the circular hole 202. Blocking the gap between the cable and the circular hole 202 can prevent external dust from entering the device without being filtered. Secondly, the rubber ring 505 can be further fixed by being squeezed.

[0039] A nut 600 is provided on the surface of the airbag 304. Before the device is used, the bolt 601 is screwed into the nut 600. The rubber block 602 at the front end of the bolt 601 will tightly fit and press the conductor on the inner surface of the airbag 304 and the cable. When the bolt 601 is screwed out, the gas in the airbag 304 can be released, thereby facilitating the removal of the cable.
