[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0026] As Figures 1 to 7 shown

[0027] A maintenance device for a communication transmission device, comprising a chassis 1 and a casing 2. The casing 2 is slidably arranged at the top of the chassis 1. A limit clamping plate 7 is slidably arranged on one side of the casing 2. A fixing seat 8 with a wedge-shaped structure is fixedly installed on the outer wall of one side of the chassis 1. A limit groove 9 is opened at the top of the fixing seat 8. The limit clamping plate 7 is adapted to the limit groove 9. Symmetrically arranged movable grooves 15 are opened on both sides of the limit clamping plate 7. Wedge-shaped clamping blocks 10 are slidably connected to the inner walls of the two movable grooves 15. Spring 16 are fixedly connected to the inner walls of one side of the two movable grooves 15. One ends of the two springs 16 are respectively connected to the outer walls of one side of the two wedge-shaped clamping blocks 10. Symmetrically arranged clamping grooves 17 are opened on both sides of the limit groove 9. Pressing blocks 11 are slidably connected to the inner walls of the two clamping grooves 17. The two wedge-shaped clamping blocks 10 are respectively adapted to the two clamping grooves 17. Dust-proof net plates 5 are symmetrically fixedly connected to both sides of the bottom of the casing 2. When it is necessary to repair the inside of the chassis 1 after long-term work, press the two pressing blocks 11 to move relatively. The two pressing blocks 11 push the two wedge-shaped clamping blocks 10 to move relatively until the two wedge-shaped clamping blocks 10 respectively disengage from the two clamping grooves 17, and the two wedge-shaped clamping blocks 10 respectively move into the two movable grooves 15. Then lift the limit clamping plate 7 to make the limit clamping plate 7 disengage from the limit groove 9. When the limit clamping plate 7 disengages from the limit groove 9, pull the casing 2 to move, realizing the disassembly effect of the casing 2. When the casing 2 moves, it can drive the two dust-proof net plates 5 to move until the two dust-proof net plates 5 respectively disengage from the two slide rails 3, so that the two dust-proof net plates 5 can be disassembled to clean the accumulated dust when the casing 2 is disassembled. After the casing 2 is disassembled, the staff can repair the inside of the chassis 1, realizing the quick disassembly of the casing 2.

[0028] In the specific implementation manner, symmetrically arranged slide rails 3 are opened at the top of the chassis 1. Slide plates 4 are slidably connected to the inner walls of the bottoms of the two slide rails 3. The bottom ends of the two dust-proof net plates 5 are respectively fixedly connected to the outer walls of the tops of the two slide plates 4. The two dust-proof net plates 5 are respectively slidably arranged on the inner walls of the two slide rails 3. Ventilation holes 6 are arranged at equal intervals on both sides of the chassis 1. The ventilation holes 6 penetrate through the slide rails 3. By arranging the ventilation holes 6 on both sides of the chassis 1, the function of ventilation and heat dissipation can be achieved. By arranging the dust-proof net plates 5 in the two slide rails 3, the function of effectively preventing dust can be achieved.

[0029] Further, a T-shaped guiding groove 12 is formed in the middle of one side of the casing 2. A guiding plate 13 with a T-shaped structure is fixedly connected to the middle of one side of the limiting clamping plate 7. The guiding plate 13 is slidably connected to the inner wall of the guiding groove 12. When it is necessary to connect the chassis 1 and the casing 2 together, the casing 2 is pushed to move horizontally through the arranged slide rail 3 and the sliding plate 4. At this time, under the action of the guiding groove 12 and the guiding plate 13, the limiting clamping plate 7 can slide on the top of the fixed seat 8 until the top of the casing 2 is in contact with the top of the chassis 1. At this time, press the limiting clamping plate 7 to move downward, and the limiting clamping plate 7 can be pressed into the limiting groove 9. After the bottom end of the limiting clamping plate 7 contacts the bottom inner wall of the limiting groove 9, under the action of the two movable grooves 15 and the two springs 16, the two wedge-shaped clamping blocks 10 can be respectively pushed into the two clamping grooves 17 to realize the limiting effect on the limiting clamping plate 7, thereby playing a stabilizing role on the casing 2 and realizing the stable connection between the chassis 1 and the casing 2. A symmetrically arranged anti-disengagement plate 14 is fixedly connected to the top of the limiting clamping plate 7. The bottoms of the two anti-disengagement plates 14 are both in contact with the outer wall of the top of the casing 2.

[0030] The implementation principle of a maintenance device for a communication transmission device in this embodiment is as follows:

[0031] When it is necessary to connect the chassis 1 and the casing 2 together, the casing 2 is pushed to move horizontally through the arranged slide rails 3 and the sliding plate 4. At this time, under the action of the guiding groove 12 and the guiding plate 13, the limit clamping plate 7 can slide on the top of the fixed seat 8 until the top of the casing 2 fits with the top of the chassis 1. At this time, press the limit clamping plate 7 to move downward, and the limit clamping plate 7 can be pressed into the limit groove 9. After the bottom end of the limit clamping plate 7 contacts the inner wall of the bottom of the limit groove 9, under the action of the two movable grooves 15 and the two springs 16, the two wedge-shaped clamping blocks 10 can be respectively pushed into the two clamping grooves 17 to realize the limiting effect on the limit clamping plate 7, thereby playing a stabilizing role on the casing 2 and realizing the stable connection between the chassis 1 and the casing 2. Then, through the ventilation holes 6 arranged on both sides of the chassis 1, the functions of ventilation and heat dissipation can be achieved. By arranging the dust-proof net plates 5 in the two slide rails 3, the function of effectively preventing dust can be achieved. When it is necessary to overhaul the inside of the chassis 1 after working for a long time, press the two pressing blocks 11 to move relatively. The two pressing blocks 11 push the two wedge-shaped clamping blocks 10 to move relatively until the two wedge-shaped clamping blocks 10 are respectively disengaged from the two clamping grooves 17, and the two wedge-shaped clamping blocks 10 respectively move into the two movable grooves 15. Then, lift the limit clamping plate 7 to make the limit clamping plate 7 disengage from the limit groove 9. After the limit clamping plate 7 disengages from the limit groove 9, through the arranged slide rails 3 and the sliding plate 4, the casing 2 can be pulled to move, realizing the disassembly effect of the casing 2. When the casing 2 moves, the two dust-proof net plates 5 can be driven to move until the two dust-proof net plates 5 are respectively disengaged from the two slide rails 3, so that the two dust-proof net plates 5 can be disassembled when the casing 2 is disassembled to clean the accumulated dust. After the casing 2 is disassembled, the staff can overhaul the inside of the chassis 1, realizing the rapid disassembly of the casing 2 and reducing the overhaul difficulty.
