[0017] Preferably, an arc-shaped support plate is fixedly connected to one side of the limiting disk opposite to the rotating disk.

[0018] Preferably, the method for using the assembleable mold for producing a fire extinguisher tank comprises the following steps:

[0019] S1: When assembling the fire extinguisher tank, place the bottom of the fire extinguisher in the guide slot, and then place the fire extinguisher cylinder in the cylinder bayonet. At this time, the bottom of the fire extinguisher cylinder is coaxial with the central axis of the fire extinguisher cylinder;

[0020] Then, the motor drives the rotating disk and the pushing disk to rotate clockwise at the same time, so that the pressure plate rod is squeezed by the first arc-shaped squeezing plate and moves to the left, and pushes the connecting plate at its end to move to the left, so that the L-shaped sliding rod slides in the sliding groove and drives the L-shaped pressure plate to move to the left. At this time, the first spring telescopic rod is stretched, and the rotating tube is pulled to slide inside the rotating gear ring, pushing the fire extinguisher cylinder on the left side of the rotating tube to move left and dock with the port at the bottom of the fire extinguisher cylinder. When the fire extinguisher cylinder and the port at the bottom of the fire extinguisher cylinder are docked, the fire extinguisher cylinder bottom is pushed to move into the circular through groove and contact the pressure plate in the circular through groove. When the pressure plate is squeezed by the bottom of the fire extinguisher cylinder, it slides on the fixed rod, causing the hinged rod to deflect and drive the squeezing plate at its end to deflect and contact the side of the bottom of the fire extinguisher cylinder, so as to fix the fire extinguisher cylinder bottom internally and prevent the fire extinguisher cylinder bottom from rotating.

[0021] S2: After the L-shaped pressure plate moves leftward out of the rotating tube and moves into the fire extinguisher cylinder, the pressure plate rod continues to move leftward and under the action of the reaction force of the first spring telescopic rod, the connecting plate squeezes the L-shaped pressure plate to deflect and abut against the inner wall of the fire extinguisher cylinder, thereby fixing the fire extinguisher cylinder;

[0022] Then, when the motor drives the rotating disk and the pushing disk to continue to rotate clockwise, the rotating gear ring rotates and rolls on the inner gear ring, driving the fire extinguisher cylinder supported by the pressure plate rod to rotate, so that the connection between the fire extinguisher cylinder and the fire extinguisher cylinder bottom is rubbed to ensure the tightness of the docking assembly between the fire extinguisher cylinder and the fire extinguisher cylinder bottom;

[0023] S3: Then, when the pressure plate rod rotates and contacts the end of the second arc-shaped extrusion plate, the pressure plate rod continues to move left, pushing the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder to move left at the same time. At this time, the sliding ring tube slides leftward when the fixed rod moves leftward and squeezes the fourth spring telescopic rod to compress. When the beveled surface of the end face of the L-shaped extrusion rod is squeezed into the inclined groove, the spring compression rod contracts and the starting end moves out of the ring groove. Then, the sliding plate moves leftward and pushes the sliding flat gear ring to slide leftward and separate from the fixed flat gear under the action of the connecting rod. At this time, the rotating gear ring drives the fire extinguisher cylinder supported by the pressure plate rod to rotate, and then drives the bottom of the fire extinguisher cylinder to rotate at the same time, and cooperates with the welding machine to weld the joint between the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder;

[0024] After welding is completed, the pressure plate rod rotates and separates from the second arc-shaped extrusion plate. At this time, the pressure plate rod is reset under the action of the reset force of the first spring telescopic rod, and the L-shaped pressure plate releases the internal support of the fire extinguisher cylinder. The pressure plate is reset through the fourth spring telescopic rod, and drives the hinged rod to deflect and reset, releasing the internal support of the extrusion plate on the bottom of the fire extinguisher cylinder, completing the assembly and welding of the fire extinguisher cylinder bottom and the fire extinguisher cylinder by the device.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, the pressure plate rod is moved leftward, so that the fire extinguisher cylinder on the left side of the rotating tube is pushed to move leftward and dock with the port at the bottom of the fire extinguisher cylinder. The deflection of the hinged rod drives the extrusion plate at its end to deflect and abut against the side surface of the bottom of the fire extinguisher cylinder, thereby internally supporting and fixing the bottom of the fire extinguisher cylinder. After the L-shaped pressure plate moves leftward and moves out of the rotating tube and into the inside of the fire extinguisher cylinder, the pressure plate rod continues to move leftward and under the action of the reaction force of the first spring telescopic rod, the connecting plate squeezes the L-shaped pressure plate to deflect and abut against the inner wall of the fire extinguisher cylinder, thereby fixing the fire extinguisher cylinder, which is convenient for the subsequent docking of the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder.

[0027] In the present invention, when the rotating disk and the pushing disk continue to rotate clockwise driven by the motor, the rotating gear ring rotates and rolls on the inner gear ring, driving the fire extinguisher cylinder supported by the pressure plate rod to rotate, so that the connection between the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder is rubbed, ensuring the tightness of the docking and assembly between the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder.

[0028] In the present invention, after the pressure plate rod rotates and collides with the end of the second arc-shaped extrusion plate, the pressure plate rod continues to move left, pushing the fire extinguisher cylinder and the fire extinguisher cylinder bottom to move left at the same time, causing the sliding plate to move left and, under the action of the connecting rod, push the sliding flat gear ring to slide left and separate from the fixed flat gear. At this time, the rotating gear ring drives the fire extinguisher cylinder supported by the pressure plate rod to rotate, and then drives the fire extinguisher cylinder bottom to rotate at the same time. The welding machine is used to weld the joint between the fire extinguisher cylinder and the fire extinguisher cylinder bottom, and the operation is simple and convenient.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown:

[0058] S1: When assembling the fire extinguisher tank, after placing the bottom of the fire extinguisher cylinder in the guide slide groove 52, the fire extinguisher cylinder is placed in the cylinder bayonet 8. At this time, the bottom of the fire extinguisher cylinder is coaxial with the central axis of the fire extinguisher cylinder;

[0059] Then, the motor 2 drives the rotating disk 41 and the pushing disk 7 to rotate clockwise at the same time, so that the pressure plate rod 46 is squeezed by the first arc-shaped squeezing plate 412 and moves to the left, and pushes the connecting plate 414 at its end to move left, so that the L-shaped sliding rod 49 slides in the sliding groove 47 and drives the L-shaped pressing plate 410 to move left. At this time, the first spring telescopic rod 48 stretches and pulls the rotating tube 44 to slide inside the rotating gear ring 43, pushing the fire extinguisher cylinder on the left side of the rotating tube 44 to move left and align with the bottom of the fire extinguisher cylinder. When the fire extinguisher cylinder body and the port of the fire extinguisher cylinder bottom are connected, the fire extinguisher cylinder bottom is pushed to move into the circular groove 53 and abut against the pressure plate 518 in the circular groove 53. When the pressure plate 518 is squeezed by the fire extinguisher cylinder bottom, it slides on the fixing rod 55, causing the hinge rod 520 to deflect and drive the squeezing plate 521 at its end to deflect and abut against the side of the bottom of the fire extinguisher cylinder bottom, thereby internally supporting and fixing the fire extinguisher cylinder bottom to prevent the fire extinguisher cylinder bottom from rotating.

[0060] S2: After the L-shaped pressure plate 410 moves leftward from the rotating tube 44 and moves into the fire extinguisher cylinder, the pressure plate rod 46 continues to move leftward and under the reaction force of the first spring telescopic rod 48, the connecting plate 414 squeezes the L-shaped pressure plate 410 to deflect and abut against the inner wall of the fire extinguisher cylinder, thereby fixing the fire extinguisher cylinder;

[0061] Then, when the motor 2 drives the rotating disk 41 and the pushing disk 7 to continue to rotate clockwise, the rotating gear ring 43 rotates and rolls on the inner gear ring 42, driving the fire extinguisher cylinder supported by the pressure plate rod 46 to rotate, so that the connection between the fire extinguisher cylinder and the fire extinguisher cylinder bottom is rubbed to ensure the tightness of the butt assembly between the fire extinguisher cylinder and the fire extinguisher cylinder bottom;

[0062] S3: Then, when the pressure plate rod 46 rotates and contacts the end of the second arc-shaped extrusion plate 413, the pressure plate rod 46 continues to move left, pushing the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder to move left at the same time. At this time, the sliding ring tube 517 slides leftward on the fixed rod 55 and squeezes the fourth spring telescopic rod 512 to compress. When the chamfered surface of the end face of the L-shaped extrusion rod 513 is squeezed into the inclined groove 515, the spring compression rod 514 contracts and the starting end moves out of the annular groove 516. Then, the sliding plate 511 moves leftward and pushes the sliding flat gear ring 58 to slide leftward and separate from the fixed flat gear 59 under the action of the connecting rod 510. At this time, the rotating gear ring 43 drives the fire extinguisher cylinder supported by the pressure plate rod 46 to rotate, and then drives the bottom of the fire extinguisher cylinder to rotate at the same time, and cooperates with the welding machine 6 to weld the joint between the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder;

[0063] After welding is completed, the pressure plate rod 46 rotates and separates from the second arc-shaped extrusion plate 413. At this time, the pressure plate rod 46 is reset under the action of the reset force of the first spring telescopic rod 48, and the L-shaped pressure plate 410 releases the internal support of the fire extinguisher cylinder. The pressure plate 518 is reset through the fourth spring telescopic rod 512, and drives the hinged rod 520 to deflect and reset, releasing the internal support of the extrusion plate 521 on the bottom of the fire extinguisher cylinder, completing the assembly and welding of the fire extinguisher cylinder bottom and the fire extinguisher cylinder by the device.

8. The method for using the assembleable mold for producing a fire extinguisher tank according to claim 5, characterized in that: The steps include: S1: When assembling the fire extinguisher tank, after placing the bottom of the fire extinguisher cylinder in the guide slide groove (52), the fire extinguisher cylinder is placed in the cylinder bayonet (8), and at this time, the bottom of the fire extinguisher cylinder is coaxial with the central axis of the fire extinguisher cylinder; Then, the motor (2) drives the rotating disk (41) and the pushing disk (7) to rotate clockwise at the same time, so that the pressing plate rod (46) is squeezed by the first arc-shaped squeezing plate (412) and moves to the left, and pushes the connecting plate (414) at its end to move to the left, so that the L-shaped sliding rod (49) slides in the sliding groove (47) and drives the L-shaped pressing plate (410) to move to the left. At this time, the first spring telescopic rod (48) stretches and pulls the rotating tube (44) to slide inside the rotating gear ring (43), pushing the fire extinguisher cylinder on the left side of the rotating tube (44) to move to the left. The fire extinguisher is docked with the port of the bottom of the fire extinguisher. When the fire extinguisher body and the port of the bottom of the fire extinguisher are docked, the bottom of the fire extinguisher is pushed to move into the circular groove (53) and abut against the pressure plate (518) in the circular groove (53). When the pressure plate (518) is squeezed by the bottom of the fire extinguisher, it slides on the fixing rod (55), causing the hinge rod (520) to deflect and drive the squeezing plate (521) at its end to deflect and abut against the side surface of the bottom of the fire extinguisher, thereby internally supporting and fixing the bottom of the fire extinguisher to prevent the bottom of the fire extinguisher from rotating. S2: After the L-shaped pressure plate (410) moves leftward from the inside of the rotating tube (44) and moves into the inside of the fire extinguisher cylinder, the pressure plate rod (46) continues to move leftward and under the action of the reaction force of the first spring telescopic rod (48), the connecting plate (414) squeezes the L-shaped pressure plate (410) to deflect and abut against the inner wall of the fire extinguisher cylinder, thereby fixing the fire extinguisher cylinder; Then, when the motor (2) drives the rotating disk (41) and the pushing disk (7) to continue to rotate clockwise, the rotating gear ring (43) rotates and rolls on the inner gear ring (42), driving the fire extinguisher cylinder supported by the pressure plate rod (46) to rotate, so that the connection between the fire extinguisher cylinder and the fire extinguisher cylinder bottom is rubbed, thereby ensuring the tightness of the butt assembly between the fire extinguisher cylinder and the fire extinguisher cylinder bottom; S3: Then, when the pressure plate rod (46) rotates and contacts the end of the second arc-shaped extrusion plate (413), the pressure plate rod (46) continues to move left, pushing the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder to move left at the same time. At this time, the sliding ring tube (517) slides leftward on the fixed rod (55) and squeezes the fourth spring telescopic rod (512) to compress. When the chamfered surface of the end face of the L-shaped extrusion rod (513) is squeezed into the inclined groove (515), the spring compression rod (514) contracts and the starting end moves out of the annular groove (516). Then, the sliding plate (511) moves leftward and pushes the sliding flat gear ring (58) to slide leftward and separate from the fixed flat gear (59) under the action of the connecting rod (510). At this time, the rotating gear ring (43) drives the fire extinguisher cylinder supported by the pressure plate rod (46) to rotate, and then drives the bottom of the fire extinguisher cylinder to rotate at the same time, and cooperates with the welding machine (6) to weld the joint between the fire extinguisher cylinder and the bottom of the fire extinguisher cylinder; After the welding is completed, the pressure plate rod (46) rotates and separates from the second arc-shaped extrusion plate (413). At this time, the pressure plate rod (46) is reset under the action of the reset force of the first spring telescopic rod (48), and the internal support of the L-shaped pressure plate (410) on the fire extinguisher cylinder is released. The pressure plate (518) is reset through the fourth spring telescopic rod (512), and drives the hinge rod (520) to deflect and reset, and the internal support of the extrusion plate (521) on the bottom of the fire extinguisher cylinder is released, and the assembly and welding of the fire extinguisher cylinder bottom and the fire extinguisher cylinder by the device are completed.
