[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0018] like Figure 1 As shown, the utility model provides a ballast fixing device for a flue gas treatment light box, including an adapter plate 4, which is fixed to the inner wall of the flue gas treatment light box through threaded holes 12. Two ballasts 1 are symmetrically fixed on the adapter plate 4, and the narrower side wall of each ballast 1 is fixed to the adapter plate 4 by screws 5. A space is left between the two ballasts 1, and heat dissipation holes 2 are provided on the opposite side walls; the heat dissipation holes 2 are in the shape of long strips, and the distribution direction is arranged along the vertical direction, and the ballast 1 is provided with a plurality of line sockets 3. By providing the heat dissipation holes 2, the heat dissipation speed of the ballast 1 can be improved and the service life of the ballast 1 can be extended.

[0019] The model of ballast 1 is VOCs ballast-Zike-PH2.

[0020] like Figure 2 As shown in FIG. 3 , the adapter plate 4 is provided with a through hole, a pipe sleeve 7 is fixedly connected to the adapter plate 4, at least two notches 8 are provided on the side wall of the pipe sleeve 7, a clamping member 10 is slidably fitted in the notch 8, a screw 5 passes through the through hole, a thread is provided on the inner side wall of the pipe sleeve 7, the screw 5 matches the thread, and an end of the screw 5 extending into the pipe sleeve 7 is provided with an inclination angle 9, and the axis of the screw 5 is aligned with the contact surface of at least two clamping members 10.

[0021] The adapter plate 4 is provided with a groove 6. When in use, the pipe sleeve 7 is inserted into the groove 6 on the adapter plate 4, and the screw 5 is tightened. The screw 5 moves along the axis of the pipe sleeve 7 toward the clamping member 10, so that the inclination angle 9 at the end of the screw 5 presses against the end surface of the clamping member 10, pushing the clamping member 10 to move outward, and finally the outer end of the clamping member 10 is clamped with the side wall of the groove 6 to achieve the fixing function. The clamping member 10 can be pressed with the screw 5, so that the clamping member 10 can continue to press the inner wall of the groove 6, and will not be disengaged. This enhances the firmness of its fixing.

[0022] The cross section of the notch 8 is a triangular structure or a square structure. By setting the notch 8 to a triangular structure or a square structure, the clamping member 10 is prevented from rotating, which affects the pushing of the clamping member 10 by the screw 5. A cone 11 is provided at one end of the clamping member 10 away from the screw 5. By providing the cone 11 at the end of the clamping member 10, the clamping performance of the clamping member 10 and the groove 6 can be improved.

[0023] The opposite surfaces of adjacent clamping members 10 are provided with inclined surfaces, and the angle of the inclined surfaces matches the angle of inclination 9. The inclined surfaces make it easier for the screw 5 to push the clamping member 10 to move. The length of the clamping member 10 is equal to the radius of the outer wall of the sleeve 7, the thread length of the screw 5 is greater than the sum of the length of the sleeve 7 and the thickness of the ballast 1, and the outer diameter of the sleeve 7 is smaller than the inner diameter of the groove 6.

[0024] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
