[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] The utility model provides a television back panel with a dustproof structure, comprising a back panel body 1, a mounting groove 2 being provided on one side of the back panel body 1, a plurality of line ports 3 being installed on one side of the mounting groove 2, a plurality of first slide grooves 4 being provided on one side of the mounting groove 2, a blocking block 5 being slidably installed in the first slide groove 4, and one end of the blocking block 5 extending to the outside of the first slide groove 4, a heat dissipation port 6 being provided on one side of the back panel body 1, and a dustproof component being installed in the heat dissipation port 6.

[0027] The positions of the plurality of first sliding slots 4 are respectively parallel to the positions of the plurality of circuit ports 3 , so that the blocking block 5 can block the circuit ports 3 when extended.

[0028] One side of each shielding block 5 is in close contact with the circuit port 3 at a parallel position, so that the shielding block 5 can shield the circuit port 3 when extended.

[0029] Among them, the blocking block 5 is installed with a compression spring 7 on one side located inside the first slide groove 4, and the other end of the compression spring 7 is connected to one side of the first slide groove 4. Through the rebound of the compression spring 7, the blocking block 5 can always block the line port 3 when the line port 3 is idle.

[0030] Among them, the dustproof component includes a dustproof net 8 and a pair of second slide grooves 9. A pair of limiting grooves 10 are symmetrically provided on both sides of the dustproof net 8. A pair of second slide grooves 9 are symmetrically opened on both sides of the heat dissipation port 6. A pair of second slide grooves 9 are symmetrically installed with a pair of trapezoidal limiting blocks 11 on the opposite side. A pair of trapezoidal limiting blocks 11 extend to the outside of the second slide groove 9 and are slidably connected to the second slide groove 9. The size of the trapezoidal limiting blocks 11 matches the size of the limiting groove 10. A pair of trapezoidal push blocks are slidably installed in the second slide grooves 9. Block 12, and a pair of trapezoidal pushing blocks 12 are symmetrically arranged. When installing the dustproof net 8, the user first places the dustproof net 8 into the heat dissipation port 6, and then rotates the rotating block 14 to make the rotating block 14 rotate and move into the second slide groove 9, thereby pushing the trapezoidal pushing block 12 to move. The inclined surface of the trapezoidal pushing block 12 is tightly attached to the inclined surface of the trapezoidal limiting block 11. At this time, the trapezoidal pushing block 12 will squeeze the trapezoidal limiting block 11, so that the trapezoidal limiting block 11 extends from the second slide groove 9 and enters the limiting groove 10, thereby fixing the dustproof net 8.

[0031] Among them, a pair of trapezoidal limit blocks 11 are symmetrically installed with a pair of tension springs 13 on the opposite side, and the other ends of the pair of tension springs 13 are respectively connected to the side of the pair of second slide grooves 9 away from each other. When removing the dustproof net 8, the user rotates the rotating block 14 in the opposite direction, and the rotating block 14 pulls the trapezoidal push block 12 so that the trapezoidal push block 12 no longer squeezes the trapezoidal limit block 11. At this time, under the action of the rebound of the tension spring 13, the trapezoidal limit block 11 slides into the second slide groove 9, so that the trapezoidal limit block 11 is disengaged from the limit groove 10 and no longer limits the dustproof net 8.

[0032] Among them, one side of the back panel body 1 is threadedly connected with a rotating block 14 at a position close to a pair of second sliding grooves 9, and the pair of rotating blocks 14 respectively extend into the inside of the second sliding grooves 9 and are rotatably connected to the trapezoidal push block 12, so as to facilitate pushing the trapezoidal push block 12 to move.

[0033] The size of the dustproof net 8 matches the size of the heat dissipation port 6 , making it easy to insert the dustproof net 8 into the heat dissipation port 6 .

[0034] The working principle of this embodiment: When the TV back panel with a dustproof structure is in use, the blocking block 5 can block the idle line port 3 to prevent dust from entering the idle line port 3. When the line port 3 needs to be used, the user pushes the line port 3 into the first slide 4 and inserts the line into the line port 3. When the user installs the dustproof net 8, the user first puts the dustproof net 8 into the heat dissipation port 6, and then rotates the rotating block 14 to rotate and move the rotating block 14 into the second slide 9, thereby pushing the trapezoidal push block 12 to move, and the inclined surface of the trapezoidal push block 12 and the inclined surface of the trapezoidal limit block 11 are aligned. When the dust net 8 needs to be disassembled and cleaned, the user rotates the rotating block 14 in the opposite direction, and the rotating block 14 pulls the trapezoidal pushing block 12 so that the trapezoidal pushing block 12 no longer squeezes the trapezoidal limiting block 11. At this time, under the action of the rebound of the tension spring 13, the trapezoidal limiting block 11 slides into the second slide groove 9, so that the trapezoidal limiting block 11 disengages from the limiting groove 10 and no longer limits the dust net 8. Then the rotating block 14 can be pulled to remove the dust net 8.

Many modifications and variations will be apparent to those skilled in the art.
