[0022] like Figures 1 to 6As shown, a protective shell for cable TV engineering signal transmission equipment includes a protective shell 1, through which the signal transmission equipment 3 is protected to prevent the signal transmission equipment 3 from being damaged by collision. Clamping structures 2 are provided at both ends of the shell wall on both sides of the inside of the protective shell 1, and the signal transmission equipment 3 is provided between the clamping structures 2. The signal transmission equipment 3 is fixed inside the protective shell by the clamping structure 2. A protective door 11 is rotatably connected to the top at the front end of the protective shell 1. A socket 12 compatible with the plug of the signal transmission equipment 3 is provided in the protective door 11. The protective shell 1 is closed by the protective door 11, so as to better protect the signal transmission equipment 3. Air vents 4 are provided on both sides and the top of the protective shell 1. The top of the air vent 4 on the top of the protective shell 1 is fixedly connected to a mounting frame 7, and the mounting frame 7 is provided inside A heat dissipation fan 8 and a protective net 9 are provided on the top of the mounting frame 7. The air vents 4 are used in conjunction with the heat dissipation fan to allow air to circulate inside the protective housing 1, thereby dissipating the heat generated by the signal transmission device 3 during operation. The protective net 9 and the mounting frame 7 are connected by a bolt structure, and the protective net 9 can be disassembled by the bolt structure, so as to facilitate the maintenance of the heat dissipation fan 8 or the cleaning of dust in the protective net 9. Dust removal brushes 5 are provided on the opposite sides of the air vents 4 on both sides of the protective housing 1, and a pulling structure 6 is provided between the two dust removal brushes 5. During long-term use, a certain amount of dust will accumulate in the air vents 4 on both sides of the protective housing 1. The dust is cleaned by the dust removal brush 5, and the dust removal brush can be moved by the pulling structure 6. Support legs 10 are fixedly connected to the four corners of the bottom of the protective housing 1;

[0023] The clamping structure 2 includes a fixed block 201, which is fixedly connected to the two ends of the shell wall on both sides of the inside of the protective shell 1. A movable sleeve 202 is sleeved on one end of the fixed block 201 close to the signal transmission device 3. A support spring 203 is fixedly connected between the inside of the movable sleeve 202 and the fixed block 201. An anti-slip layer is fixedly connected to the side of the movable sleeve 202 that is in contact with the signal transmission device 3. The movable sleeve 202 is supported by the support spring 203 so that the movable sleeve 202 is against the signal transmission device 3, thereby fixing the signal transmission device 3. The support spring 203 is a hard spring, which has a certain buffering effect on the signal transmission device 3 when the left and right sides of the protective shell 1 are collided, and is not easy to shake.

[0024] The pulling structure 6 includes a through slot 601, which is opened on both sides of the bottom of the protective shell 1, and the through slot 601 is located at the bottom of the dust removal brush 5. A connecting rod 602 is provided at the bottom of the protective shell 1. The connecting rod 602 is a U-shaped structure. Both ends of the connecting rod 602 are inserted in the through slot 601 and fixedly connected to the bottom of the dust removal brush 5. A fixed plate 603 is fixedly connected to the middle position of both sides of the bottom of the protective shell 1. A guide rod 604 is fixedly connected on both sides between the two fixing plates 603. The guide rod 604 is inserted in the connecting rod 602. A movable rod 605 is fixedly connected to the front end of the connecting rod 602. The movable rod 605 is inserted in the fixed plate 603 away from the end of the connecting rod 602, and is fixedly connected to a limiting plate 606. A spring 607 is fixedly connected between the front end of the rod 602 and the fixed plate 603, and the spring 607 is sleeved on the guide rod 604. When the air holes 4 on both sides of the protective shell 1 need to be cleaned, the movable rod 605 is pulled to drive the dust removal brushes 5 at both ends of the connecting rod 602, so that the dust removal brushes 5 clean the air holes 4. When the connecting rod 602 moves toward the front end along the guide rod 604, the connecting rod 602 squeezes the spring 607. After pulling the connecting rod 602, the connecting rod 602 can be reset by the tension of the spring 607. At the same time, the guide rod 604 can prevent the spring 607 from bending during the squeezing process.
