[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] See Figures 1 to 5To further elaborate on this application: Combination Figure 1 and Figure 2 A bag filter dust collector housing door locking mechanism includes a housing 10, a pressing mechanism 30, and a top cover 20. The housing 10 has a mounting groove 100 for mounting the top cover 20. The pressing mechanism 30 is arranged around the top cover 20. In this embodiment, the housing 10 has a placement groove 110, and the pressing mechanism 30 is located within the placement groove 110. The placement groove 110 is formed on the side wall of the mounting groove 100 and communicates with it.

[0017] Combination Figure 3 and Figure 4 The clamping mechanism 30 includes a driving component 40 and a plurality of clamping blocks 50, the clamping blocks 50 being rotatably connected to the housing 10; the top cover 20 is provided with a slot 200 for placing the clamping blocks 50; wherein, the slot 200 is located on the side of the top cover 20, and the driving component 40 is used to drive the clamping blocks 50 to engage or disengage from the slot 200.

[0018] It also includes a connecting rod assembly 60 connecting the driving component 40 and the clamping block 50. The connecting rod assembly 60 is used to drive the clamping block 50 to rotate synchronously. By driving the connecting rod assembly 60 through the driving component 40, the clamping block 50 is driven to rotate synchronously into or out of the slot 200, thereby locking and unlocking the top cover 20.

[0019] Combination Figure 5 In this embodiment, the linkage assembly 60 includes a plurality of linkages 610 and a hinge plate 620 rotatably connecting the linkages 610 and the housing 10. The clamping block 50 is slidably connected to the linkages 610, and the driving component 40 is rotatably connected to the linkages 610. Adjacent linkages 610 are rotatably connected via the hinge plate 620, forming a closed-loop linkage structure with interconnected ends.

[0020] This application enables the drive component 40 to drive the connecting rod assembly 60 to rotate the clamping block synchronously, thereby pressing and fixing the top cover 20 onto the housing 10. This allows for quick unlocking or locking of the top cover 20, greatly reducing operational difficulty and shortening maintenance and replacement time.

[0021] Combination Figure 5The aforementioned clamping block 50 is slidably connected to the connecting rod 610; wherein, the clamping block 50 is provided with a sliding groove 500, and the connecting rod 610 is provided with a sliding shaft that moves along the sliding groove 500. When the driving component 40 drives the connecting rod assembly 60 to move, the sliding shaft moves along the sliding groove 500, simultaneously driving the clamping block 50 to rotate, causing the clamping block 50 to move into the slot 200 to press the top cover 20, or to move out of the slot 200 to release the top cover 20.

[0022] Combination Figure 5 The clamping block 50 includes a movable part 510 and a locking part 520. The movable part 510 has a length greater than that of the locking part 520. A hinge hole is provided at the connection between the movable part 510 and the locking part 520 for rotatably connecting the housing 10. When the connecting rod 610 drives the locking part 520 to rotate via the movable part 510, the lever principle makes it easier to operate the clamping block 50.

[0023] In one embodiment, an elastic sealing component is provided between the housing 10 and the top cover 20 to seal the housing 10. The elastic sealing component may be a rubber gasket. When the pressing block 50 presses against the top cover 20, the top cover 20 compresses the elastic sealing component, which fills the gap between the top cover 20 and the housing 10, preventing smoke leakage.

[0024] Combination Figure 5 The driving component 40 includes a driving handle 410 and a driving plate 420, with a connecting shaft 430 connecting the driving plate 420 and the driving handle 410. The length of the driving handle 410 is greater than the length of the driving plate 420. The driving plate 420 is slidably connected to the linkage assembly 60. The driving handle 410 makes it easier to drive the linkage assembly 60, reducing operational difficulty. In this embodiment, there is one driving component 40; however, there can be multiple driving components 40, which is not limited here. In embodiments not shown, the driving handle 410 can be replaced by a motor, with the motor connected to the connecting shaft 430 via a transmission connection.

[0025] In one embodiment, a guide structure is also included, the guide structure including a first guide portion disposed on the locking portion 520 and a second guide portion disposed on the slot 200; wherein the guide portions are both arc-shaped; the guide structure can guide the locking portion 520 to move into the slot 200.
