[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As Figures 1-6 shown, a glass fiber coated composite high-temperature filter bag that is easy to disassemble and assemble includes a bag body 1. A filter bag ring plate 2 is fixed at the top of the bag body 1. A skeleton ring plate 3 is placed in the groove at the top of the filter bag ring plate 2. The skeleton body 4 at the bottom of the skeleton ring plate 3 passes through the filter bag ring plate 2 and is inserted into the bag body 1 for fixation. Two clamping blocks 6 are symmetrically fixed on the outer wall of the skeleton ring plate 3, and the clamping blocks 6 are stuck in the L-shaped notches 5 provided at the top of the filter bag ring plate 2. A positioning ring 7 is placed on the top of the filter bag ring plate 2. The limiting block 8 fixed at the bottom of the positioning ring 7 is inserted from the top of the L-shaped notch 5, and positioning parts 9 are symmetrically arranged inside the limiting block 8. The positioning parts 9 are used to connect the limiting block 8 and the skeleton ring plate 3.

[0025] With the above structural design, during assembly, the skeleton body 4 is inserted into the bag body 1 through the filter bag ring plate 2. At this time, the skeleton ring plate 3 is stuck in the top groove of the filter bag ring plate 2, and the surface of the skeleton ring plate 3 extends beyond the top groove of the filter bag ring plate 2. At the same time, the clamping block 6 is inserted from the top of the L-shaped notch 5. Then, the skeleton ring plate 3 and the skeleton body 4 are rotated together, and the clamping block 6 immediately rotates to the horizontal part of the L-shaped notch 5. At this time, a preliminary fixation is formed between the filter bag ring plate 2 and the skeleton ring plate 3. Then, the positioning ring 7 is placed on the top of the filter bag ring plate 2 and outside the skeleton ring plate 3, and the limiting block 8 is inserted from the top of the L-shaped notch 5. At this time, the limiting block 8 and the clamping block 6 fill the L-shaped notch 5, and at the same time, the positioning part 9 connects the limiting block 8 and the skeleton ring plate 3 together, making the positioning ring 7 unable to break away. At this time, the skeleton ring plate 3 cannot rotate inside the filter bag ring plate 2 to complete the installation. In this way, the assembly is very fast and has high firmness, improving the disassembly and assembly efficiency and stability.

[0026] The top surface of the positioning ring 7 is aligned with the top surface of the skeleton ring plate 3, and the inner wall is in contact with the outer wall of the skeleton ring plate 3. The outer diameter of the positioning ring 7 is the same as the outer shape of the filter bag ring plate 2. The outer walls of the clamping block 6 and the limiting block 8 are adapted to fit the L-shaped notch 5, and the clamping block 6 and the limiting block 8 are in close contact with each other. The outer walls of the clamping block 6 and the limiting block 8 are designed in an arc shape, and the outer wall radian of the clamping block 6 and the limiting block 8 is the same as the outer wall radian of the filter bag ring plate 2.

[0027] Through the above structural design, the appearance of the positioning ring 7, the clamping block 6, and the limiting block 8 is designed to be adapted to the skeleton ring plate 3 and the filter bag ring plate 2. After the assembly is completed, a relatively complete ring plate structure is formed between the positioning ring 7, the clamping block 6, and the limiting block 8 and the skeleton ring plate 3 and the filter bag ring plate 2. There are no protruding or uneven parts as a whole, making the overall aesthetics and flatness very good, the same as the appearance of the conventional filter bag structure, thus meeting the appearance needs of most users and being very practical.

[0028] The positioning part 9 includes an insertion block 901 that slides in a rectangular opening inside the limiting block 8. The insertion block 901 is inserted into a corresponding insertion opening opened on the side wall of the skeleton ring plate 3. A spring 902 is connected between the insertion block 901 and the inner wall of the opening of the limiting block 8. A round rod 903 is fixed on one side of the insertion block 901. The round rod 903 passes through a rectangular opening inside the positioning part 9 and is inserted into a cylindrical opening designed outside the positioning part 9. A threaded cover 905 is threadedly connected to the outer end of the cylindrical opening. A cylinder rod 904 is fixed on one side of the threaded cover 905. The round rod 903 is inserted into its interior from a circular opening corresponding to one side of the cylinder rod 904. A cylindrical head 906 is fixed at one end of the round rod 903. The cylindrical head 906 is in contact with the inner wall of the cylinder rod 904, and the outer diameter of the cylindrical head 906 is greater than the outer diameter of the round rod 903. At the same time, the circular opening at one end of the cylinder rod 904 is in contact with the outer wall of the round rod 903.

[0029] By designing the positioning part 9, when the positioning ring 7 and the limit block 8 are placed to limit the clamping block 6, the insertion block 901 is first squeezed into the rectangular opening by the side wall of the skeleton ring plate 3 and compresses the spring 902. At the same time, the round rod 903 also moves a short distance into the inside of the cylinder rod 904. After the positioning ring 7 is placed, the insertion block 901 reaches the corresponding socket opened on the side wall of the skeleton ring plate 3. At this time, the insertion block 901 is ejected by the spring 902 and inserted into the opening to fix the positioning ring 7 and the clamping block 6. When disassembling, rotate the threaded cover 905 to release the threaded connection with the cylindrical opening, and then pinch the threaded cover 905 with both hands and pull it outwards. The cylinder rod 904 slides outside the round rod 903. Finally, the cylindrical head 906 fits against the inner side of the end face of the cylinder rod 904 with the circular opening. Then pull the threaded cover 905 again. The cylinder rod 904 drives the cylindrical head 906 and the round rod 903 to move. The round rod 903 pulls the insertion block 901 out of the socket on the side wall of the skeleton ring plate 3, and the positioning ring 7 can be removed to release the fixation, making the disassembly and assembly of the positioning ring 7 very convenient, and the installation is firm. Cooperating with the clamping block 6 and the L-shaped notch 5, a convenient and firm disassembly and assembly structure is formed between the filter bag and the skeleton. Moreover, the threaded cover 905 protects the round rod 903, so that the insertion block 901 will not loosen easily, and the stability is very good. It should be noted that the contact surfaces of the cylindrical head 906, the cylinder rod 904 and the round rod 903 are all designed as smooth surfaces. When rotating the threaded cover 905, the cylinder rod 904 rotates outside the cylindrical head 906 and the cylinder rod 904 without much resistance.

[0030] Two screwdriver slots 907 are provided on the outer wall of the threaded cover 905, and the screwdriver slots 907 are used to dock with the correspondingly adapted rotating screwdriver bits.

[0031] Furthermore, the outer wall of the threaded cover 905 is also designed to be aligned with the outer wall of the limit block 8. Then when disassembling it, just insert a screwdriver into the screwdriver slot 907 and rotate the threaded cover 905 to disengage it, which is very convenient.

[0032] Working principle: During assembly, the skeleton body 4 is inserted into the bag body 1 through the filter bag ring plate 2, and the skeleton ring plate 3 is stuck in the top groove of the filter bag ring plate 2. At the same time, the clamping block 6 is inserted from the top of the L-shaped notch 5. Then, the skeleton ring plate 3 is rotated, and the clamping block 6 rotates to the horizontal part of the L-shaped notch 5. Then, the positioning ring 7 is placed on the top of the filter bag ring plate 2 and outside the skeleton ring plate 3, and the limiting block 8 is inserted from the top of the L-shaped notch 5. At the same time, the plug 901 is first compressed into the rectangular opening by the extrusion of the side wall of the skeleton ring plate 3 and compresses the spring 902. At the same time, the round rod 903 also moves a short distance into the cylinder rod 904. After the positioning ring 7 is placed, the plug 901 reaches the corresponding socket opened on the side wall of the skeleton ring plate 3. At this time, the plug 901 is ejected by the spring 902 and inserted into the opening to fix the positioning ring 7 and the clamping block 6. At this time, the limiting block 8 and the clamping block 6 fill the L-shaped notch 5, and the skeleton ring plate 3 cannot rotate inside the filter bag ring plate 2 to complete the installation. When disassembling, rotate the threaded cover 905 to release the threaded connection with the cylindrical opening. Then, pinch the threaded cover 905 with both hands and pull it outwards. The round rod 903 can pull the plug 901 out of the socket on the side wall of the skeleton ring plate 3. Finally, take away the positioning ring 7 and then rotate the skeleton ring plate 3.
