[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a dust removal filter bag which is easy to disassemble and assemble. Figure 1 、 Figure 2 and Figure 3 As shown, the dust filter bag includes a mounting plate 1, a first connecting end 2 fixedly mounted on the mounting plate 1, a second connecting end 3 movably mounted on the first connecting end 2, and a filter bag body 4 fixedly mounted on the second connecting end 3. The bottom of the second connecting end 3 is fixedly connected to a plug ring 5, the inner wall of the plug ring 5 is fixedly connected to a clamping block 6, the interior of the first connecting end 2 is provided with a slot 7 adapted to the plug ring 5, and the interior of the first connecting end 2 is provided with an L-shaped clamping groove 8.

[0027] The first connection end 2 and the second connection end 3 are both annular, and the filter bag body 4 and the second connection end 3 are an integrated structure. When installing the filter bag body 4, it is first necessary to make the filter bag body 4 pass through the first connection end 2, and then manually align the plug ring 5 and the card block 6 on the second connection end 3 with the slot 7 and the L-shaped card slot 8 on the first connection end 2, and then move the second connection end 3 so that the plug ring 5 and the card block 6 are respectively inserted into the slot 7 and the L-shaped card slot 8, wherein the L-shaped card slot 8 is L-shaped as a whole. After the block 6 comes into conflict with the inner wall of the L-shaped slot 8, it is necessary to rotate the second connecting end 3 horizontally so that the block 6 continues to move a certain distance inside the L-shaped slot 8 until the block 6 comes into secondary conflict with the inner wall of the L-shaped slot 8. At this time, the inner wall of the L-shaped slot 8 will fix the block 6, and then fix the filter bag body 4 to complete the installation of the filter bag body 4. When disassembling the filter bag body 4, you only need to rotate it in the opposite direction and pull up the second connecting end 3 to remove the filter bag body 4 from the first connecting end 2.

[0028] Furthermore, in order to improve the firmness of the filter bag body 4 when it is installed on the first connecting end 2, as shown in FIG. Figure 2 、 Figure 4 and Figure 6 As shown, a fixed shell 11 is fixedly connected to the first connecting end 2, and an insertion rod 12 is movably connected inside the fixed shell 11. The insertion rod 12 passes through the fixed shell 11, and one end of the insertion rod 12 is rotatably connected to an adjustment handle 14, and one side of the adjustment handle 14 is in contact with the side of the fixed shell 11 away from the second connecting end 3.

[0029] A through hole 16 is provided on the first connecting end 2, and the end of the insertion rod 12 away from the adjustment handle 14 is movably connected inside the through hole 16. The through hole 16 is connected to the slot 7, and a socket 15 adapted to the insertion rod 12 is provided on the side surface of the insertion ring 5.

[0030] The adjusting handle 14 can be rotated ninety degrees on the fixed shell 11. When the staff bends the adjusting handle 14, the adjusting handle 14 can drive the plug rod 12 connected thereto to move. The plug rod 12 will present two states under the pull of the adjusting handle 14. The first state is that the plug rod 12 extends through the through hole 16 to the inside of the slot 7, and the second state is that the plug rod 12 is retracted inside the fixed shell 11 and the through hole 16.

[0031] When installing the filter bag body 4, you first need to bend the adjusting handle 14 so that the insertion rod 12 is retracted inside the fixed shell 11 and the through hole 16, and then align the plug ring 5 on the second connecting end 3 with the block 6 to the slot 7 and the L-shaped slot 8 on the first connecting end 2, and then move the second connecting end 3 so that the plug ring 5 and the block 6 are respectively inserted into the slot 7 and the L-shaped slot 8. When the block 6 and the inner wall of the L-shaped slot 8 come into conflict, the second connecting end 3 is rotated horizontally so that the block 6 continues to move a distance inside the L-shaped slot 8 until the block 6 and the inner wall of the L-shaped slot 8 come into conflict again. At this time, the socket 15 on the plug ring 5 also just comes to the insertion rod 12, and then by bend the adjusting handle 14, the adjusting handle 14 can drive the insertion rod 12 to move, so that the insertion rod 12 is inserted into the socket 15, thereby improving the firmness of the filter bag body 4 and the second connecting end 3 installed on the first connecting end 2.

[0032] In order to improve the stability of the adjustment handle 14 during operation, Figure 2 、 Figure 4 and Figure 6 As shown, a second spring 13 is sleeved on the side surface of the insertion rod 12 , one end of the second spring 13 is fixedly connected to the insertion rod 12 , and the other end of the second spring 13 is fixedly connected to the inside of the fixed shell 11 .

[0033] The state of the inserting rod 12 is controlled by the adjusting handle 14, and through the arrangement of the second spring 13, a pushing force can be applied to the inserting rod 12, so that the adjusting handle 14 is tightly attached to the fixing shell 11, thereby effectively improving the stability of the adjusting handle 14, and the adjusting handle 14 can better adjust the position of the inserting rod 12.

[0034] It should be noted that, in order to facilitate the staff to install the filter bag body 4, as shown in Figure 2 、 Figure 4 and Figure 5 , the inside of the inserting slot 7 is provided with a pressing plate 9, the side surface of the pressing plate 9 is in sliding contact with the inner wall of the inserting slot 7, the inside of the inserting slot 7 is provided with a first spring 10, one end of the first spring 10 is fixedly connected to the bottom of the pressing plate 9, and the other end of the first spring 10 is fixedly connected to the bottom inner wall of the inserting slot 7.

[0035] When installing the filter bag body 4, the inserting ring 5 on the second connecting end 3 is inserted into the inserting slot 7 on the first connecting end 2, in this process, the inserting ring 5 will come into contact with the pressing plate 9, with the continuous movement of the inserting ring 5, the inserting ring 5 will drive the pressing plate 9 to move inside the inserting slot 7, and compress the first spring 10, and the first spring 10 will always apply a pushing force to the pressing plate 9, when the clamping block 6 comes into contact with the inner wall of the L-shaped clamping slot 8 again, the adjusting handle 14 needs to be moved, so that the inserting rod 12 is inserted into the inserting hole 15, and at this time, due to the existence of the first spring 10, the pressing plate 9 will push the inserting ring 5 tightly, thereby reducing the possibility that the inserting hole 15 and the inserting rod 12 are misaligned due to the rotation of the inserting ring 5, so as to ensure that the inserting rod 12 can be smoothly inserted into the inserting hole 15.

[0036] Further, in order to improve the stability of the movement of the pressing plate 9, as shown in Figure 2 、 Figure 4 and Figure 5 , the top of the pressing plate 9 is movably connected to the bottom of the inserting ring 5, and the first spring 10 is provided in a plurality of, and the plurality of first springs 10 are arranged in a ring array.

[0037] The arrangement of the plurality of first springs 10 helps to reduce the possibility of tilting or deviation of the pressing plate 9 during movement, thereby improving the stability of the movement of the pressing plate 9.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
