[0047] When the filter 4 is installed at the top of the bracket 3 and the bracket 3 is slidably installed on the support plate 2, the filter 4 is installed in the cabinet 1, the sliding strip 6 and the sliding groove one 9 can ensure that the bracket 3 remains stable during movement and avoids shaking or deviating from the track, the matched sliding groove one 9 and sliding strip 6 can reduce the friction area, thereby reducing the friction resistance, making the movement of the bracket 3 more labor-saving and smooth, the limiting column 13 is arranged, the limiting column 13 also slides in the sliding groove four 14 when the bracket 3 slides on the top of the support plate 2, when the limiting column 13 slides to the outermost end of the sliding groove four 14, the surface thereof abuts against the outer end surface of the inner cavity of the sliding groove four 14, thereby limiting the limiting column 13 at the position and preventing the limiting column 13 from continuously sliding outward, thereby preventing the bracket 3 from continuously sliding outward and preventing the filter 4 from falling and being damaged;

[0048] When the limiting column 13 slides to the outermost end of the sliding groove four 14, the bracket 3 is dragged out by two-thirds, and the filter 4 can maintain the original height when being removed from the cabinet 1, so that the filter 4 does not need to be placed on the ground or supported by other personnel for maintenance, and the maintenance work of the maintenance personnel is facilitated.

[0049] Refer to Figures 6-8The buckle piece A5 is provided with two and is fixedly installed on the left and right sides of the filter 4 respectively, the buckle piece A5 comprises a fixed plate one 51 fixedly connected on the left and right sides of the filter 4, three U-shaped protrusions 52 are arranged at equal intervals and are fixedly installed on the bottom of the fixed plate one 51, a sliding groove two 53 is formed on the left and right sides of the U-shaped protrusion 52, a clamping block one 55 is located in the sliding groove two 53, and the surface of the clamping block one 55 is in abutment with the inner wall of the sliding groove two 53, the length of the sliding groove two 53 is greater than the length of the clamping block one 55, so that the clamping block one 55 can slide transversely in the sliding groove two 53, the outer surface of the clamping block one 55 is arc-shaped, and a spring one 54 is fixedly connected to the inner side of the central part of the clamping block one 55.

[0050] By moving the filter 4 downward to be installed in the bracket 3, the buckle piece A5 is aligned with the buckle piece B10 in the process of moving downward, and then the U-shaped protrusion 52 is inserted into the U-shaped groove 102, in the process of inserting, the outer side surface of the clamping block one 55 is in abutment with the surface of the fixed plate two 101, and then the outer side surface of the clamping block one 55 is subjected to the extrusion force of the fixed plate two 101, because the outer side of the clamping block one 55 is arc-shaped, through force decomposition, the clamping block one 55 is subjected to the component force in the direction of the sliding groove two 53, and then the clamping block one 55 slides into the sliding groove two 53 while compressing the spring one 54, when the filter 4 is moved downward to the bottom and is in abutment with the bottom of the inner cavity of the bracket 3, the bottom of the fixed plate one 51 is not in abutment with the top of the fixed plate two 101, the bottom of the U-shaped protrusion 52 is in abutment with the bottom of the inner cavity of the U-shaped groove 102, and the clamping block one 55 located on the left and right sides of the U-shaped protrusion 52 is just in the position corresponding to the clamping groove two 103, and then the clamping block one 55 is clamped in the clamping groove two 103 under the action of the spring one 54;

[0051] The top of the U-shaped protrusion 52 is a horizontal section and is in abutment with the top of the inner cavity of the clamping groove two 103, when the filter 4 is pulled upward, the top of the clamping block one 55 is subjected to the force perpendicular to the force receiving surface, the clamping block one 55 is clamped in the clamping groove two 103 and cannot be pulled out, and then the filter 4 cannot be taken out of the bracket 3, so that the filter 4 is clamped and fixed to the bracket 3, and the stability during installation is improved.

[0052] The connecting rod 56 is L-shaped and includes a horizontal rod fixedly connected to the inner top of the clamping block 55 and a vertical rod fixedly connected to the end of the horizontal rod away from the clamping block 55. The U-shaped protrusion 52 is internally provided with a sliding groove 57 on each of the left and right sides and in communication with the sliding groove 53 on the same side. The vertical rod is located in the sliding groove 57 and abuts against the inner wall of the sliding groove 57. The length of the sliding groove 57 is greater than the width of the vertical rod, so that the vertical rod can slide horizontally in the sliding groove 57. The electromagnet 58 is fixedly installed in the center of the inner part of the U-shaped protrusion 52 and corresponds to the two connecting rods 56. The two connecting rods 56 are made of a material that can be magnetized, such as iron. When the electromagnet 58 is energized, an electric current will pass through the coil, and then a magnetic field will be generated. The two connecting rods 56 will slide in the sliding groove 57 towards the electromagnet 58. The size of the electric current can be adjusted so that the two connecting rods 56 can be attracted by the electromagnet 58.

[0053] When it is necessary to remove the filter 4 from the bracket 3, the switches for controlling the three electromagnets 58 are turned on through the control panel. When the electromagnet 58 is energized, an electric current will pass through the coil, and then a magnetic field will be generated. The two connecting rods 56 will slide in the sliding groove 57 towards the electromagnet 58 and be attracted to the electromagnet 58. When the connecting rod 56 is attracted to the electromagnet 58, the connecting rod 56 drives the clamping block 55 to completely slide into the sliding groove 53 and is no longer clamped in the clamping groove 103. Thus, the U-shaped protrusion 52 can be pulled out of the U-shaped groove 102, and the filter 4 can be removed from the bracket 3. The disassembly is simple and convenient. After the disassembly is completed, the switches of the electromagnets 58 are turned off.

[0054] With reference to Figures 3-5 The clamping assembly 7 is fixedly installed at the bottom center of the bracket 3. The cavity 8 is formed at the top of the support plate 2 and in communication with the two sliding grooves 9. The clamping assembly 7 is located in the cavity 8.

[0056] When the bracket 3 needs to be pulled out of the cabinet 1, the hemispherical clamping block 74 clamped in the square clamping groove one 75 is subjected to force, and through force decomposition, the hemispherical clamping block 74 is subjected to a force in the direction of the through hole 76, and then the V-shaped spring sheet 72 is deformed under force, and then the slide column 73 drives the hemispherical clamping block 74 to slide in the through hole 76 in the direction away from the square clamping groove one 75, and then the hemispherical clamping block 74 slides out of the square clamping groove one 75, and the bracket 3 is limited by the cooperation of the limiting column 13 and the sliding groove four 14, and when the bracket 3 is pulled to the point where it cannot be pulled, the hemispherical clamping block 74 just slides to correspond to the square clamping groove one 75 on the outer side, and then the hemispherical clamping block 74 is clamped in the square clamping groove one 75 under the action of the V-shaped spring sheet 72, and when the hemispherical clamping block 74 is clamped in the square clamping groove one 75, the bracket 3 cannot slide up and down in the support plate 2, avoiding the bracket 3 from shaking in the support plate 2 due to vibration, and improving the stability of the device.
