[0021] Embodiment 1:

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: an expandable bag cage for bag dust collector, comprising: a bag cage 1, a bag 2 is arranged between the bag cages 1, the bag cage 1 is connected with a fixing ring 3, the fixing ring 3 is provided with a connecting groove 5, the connecting groove 5 is connected with a movable groove 6 and a slot 12, the movable groove 6 is connected with a movable block 10, the movable block 10 is provided with a chamfer 11, the movable block 10 is connected with a spring 7 and a guide block 9, the guide block 9 is connected with a guide groove 8, the slot 12 is connected with a mounting block 13, and the mounting block 13 is connected with a positioning ring 4;

[0023] Align the mounting block 13 on the positioning ring 4 with the connecting groove 5, that is, between the movable block 10 and the connecting groove 5, and on the side away from the slot 12, and then rotate the positioning ring 4 to make the mounting block 13 contact the chamfer 11, and the movable block 10 moves away from each other through the chamfer 11. The movable block 10 compresses the spring 7 and drives the guide block 9 to move in the guide groove 8. When the mounting block 13 passes through the movable block 10 and one end of the mounting block 13 completely enters the slot 12, the movable block 10 returns to its original position under the action of the elastic force of the spring 7 itself, and the installation is completed.

[0024] Embodiment 2:

[0025] On the basis of the first embodiment, in order to facilitate the installation and fixation of the quick cloth bag 2, one side of the fixing ring 3 is fixedly connected to one end of the bag cage 1, and a connecting groove 5 is provided on the other side of the fixing ring 3. There are two connecting grooves 5, and the connecting grooves 5 are centrally symmetrical with the center of the fixing ring 3. The connecting grooves 5 are connected through a pair of movable grooves 6. The movable grooves 6 are provided inside the fixing ring 3. The movable grooves 6 are respectively on the left and right sides of the connecting grooves 5. The inner walls of the movable grooves 6 are slidably connected with movable blocks 10. The front and rear sides of one end of the movable block 10 are both provided with chamfers 11, and the chamfers 11 are at the end away from the movable groove 6. The center of the other end of the movable block 10 is respectively and One end of the spring 7 is fixedly connected, the spring 7 is in the movable groove 6 and is parallel to the movable groove 6, and the other end of the spring 7 is fixedly connected to the inner wall of the movable groove 6, the positioning ring 4 is on one side of the fixed ring 3, and the positioning ring 4 and the fixed ring 3 are in active contact, the inner wall of the positioning ring 4 and one end of the cloth bag 2 are fixedly connected, and a mounting block 13 is fixedly connected to one side of the positioning ring 4, the mounting block 13 is on the side close to the fixed ring 3, there are two mounting blocks 13, and the mounting blocks 13 are centrally symmetrical, the mounting blocks 13 are respectively connected to the connecting grooves 5, and one end of the mounting block 13 is in contact with the chamfer 11, and the other end of the mounting block 13 is slidably connected to the inner wall of the slot 12;

Since both ends of the mounting block 13 are consistent with the chamfer 11, the movement of the mounting block 13 causes the movable block 10 to move away from each other through the chamfer 11, and the movable block 10 compresses the spring 7. When the movable block 10 is not separated, the spring 7 is compressed, making the fit between the movable blocks 10 more stable. When the mounting block 13 passes through the movable block 10 and one end of the mounting block 13 completely enters the slot 12, the movable block 10 is restored to its original position under the action of the spring 7's own elastic force. After the movable block 10 is restored to its original position, without rotating the positioning ring 4, the movable block 10 can prevent the mounting block 13 from escaping from the slot 12, thereby completing the installation, thereby facilitating the rapid installation and fixation of the cloth bag 2.

[0027] Embodiment three:

[0028] On the basis of the second embodiment, in order to make the movable block 10 move more stably, the front and rear walls of one end of the movable block 10 are fixedly connected with a guide block 9, and the guide block 9 is slidably connected with a guide groove 8 at one end close to the spring 7. The guide groove 8 is provided in the fixed ring 3, and the guide groove 8 is connected with the movable groove 6 through, and the guide groove 8 is parallel to the spring 7;

[0029] During the installation process, while the movable block 10 moves away from each other, the movable block 10 drives the guide block 9 to slide in the guide groove 8, thereby achieving a more stable movement of the movable block 10.

[0030] In actual use, the mounting block 13 on the positioning ring 4 is aligned with the connecting groove 5, that is, between the movable block 10 and the connecting groove 5, and on the side away from the slot 12, and then the positioning ring 4 is rotated to make the mounting block 13 contact the chamfer 11, and the movable block 10 moves away from each other through the chamfer 11. The movable block 10 compresses the spring 7 and drives the guide block 9 to move in the guide groove 8. When the mounting block 13 passes through the movable block 10 and one end of the mounting block 13 completely enters the slot 12, the movable block 10 returns to its original position under the action of the elastic force of the spring 7 itself, and the installation is completed.
