Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a lifting type fire extinguishing device. Background Art

[0002] In key areas where flammable and explosive materials are present, hanging fire extinguishers are often installed. They contain a certain amount of fire extinguishing agent. When the temperature reaches the trigger value, the fire extinguishing agent is automatically sprayed out to quickly extinguish the fire. At present, most hanging fire extinguishers are installed using hooks and hanging ears. They are hung on the ceiling, roof, etc., which makes them prone to shaking. Patent No. ZL202321585363.7 discloses a hanging fire extinguisher, which includes a fire extinguisher body, a connecting plate arranged at the top of the fire extinguisher body, a lifting and adjusting mechanism arranged at the top of the connecting plate, and a positioning mechanism arranged at the bottom of the connecting plate. A hook is fixed to the top of the fire extinguisher body, and a hook is arranged at the bottom of the connecting plate. The hook and the hook are connected to each other. The positioning mechanism is used to fix the position of the hook, and the lifting and adjusting mechanism is used to drive the fire extinguisher body to move up and down. Among them, starting the second motor can drive the rotating column to rotate, thereby causing the connecting rope to be rolled downward to pay out the line, thereby driving the fire extinguisher body to move downward, thereby facilitating the replacement of the fire extinguisher body and greatly improving the convenience during use. However, the solution mentioned in the above patent controls the rise and fall of the fire extinguisher body by winding and releasing the connecting rope reel. Under the traction of the connecting rope reel, the fire extinguisher body is in a suspended state, with obvious shaking, poor stability, and a safety risk. Summary of the Invention

[0034] Working principle:

[0035] First, install the hanging bracket 1 on the ceiling, roof, etc., and connect the fire extinguisher 2 to the bottom of the extension seat 5. Start the lifting motor 7. Driven by the lifting motor 7, the power seat 4 moves vertically downward, and one side of the power gear 9 engages with the fixed rack 6 for transmission. Since the fixed rack 6 is fixed, the power gear 9 moves downward relative to the fixed rack 6, causing the power gear 9 to rotate downward. At the same time, the other side of the power gear 9 engages with the extension rack 8 for transmission. Since the extension rack 8 is movable, the extension rack 8 moves downward relative to the power gear 9, causing the extension seat 5 to move downward, and the power seat 4 and the extension seat 5 extend and retract synchronously and in the same direction. Conversely, driven by the lifting motor 7, the power seat 4 moves vertically upward, synchronously driving the extension seat 5 to move upward until the extension seat 5 is embedded in the power seat 4, and the power seat 4 is embedded in the fixed seat 3, thereby realizing the lifting and lowering adjustment of the fire extinguisher 2.
