When a water pipe terminal faucet is damaged, a faucet is not closed or a water pipe bursts, and when no one is in a house, tap water can flow outwards all the time, water resources can be wasted, accumulated water on the ground can be caused in serious cases, and damage is caused to floors, furniture, circuits and the like.

Disclosure of Invention

The invention aims to provide an overcurrent cutoff device to solve the problems.

The technical scheme for solving the technical problems is as follows:

an overcurrent cutoff device comprising: the circulating pipe and the mounting block are arranged on the outer side of the circulating pipe;

a first gear, a second gear, a connecting component, a third gear and a shifting component are sequentially arranged in the mounting block along the water flow direction; the first gear is connected with the impeller; the second gear is provided with a concentric fourth gear, and the second gear is meshed with the first gear; the connecting assembly comprises a sliding rod and a fifth gear sleeved on the sliding rod; the sliding rod penetrates through the side wall of the mounting block, and the fifth gear is matched with the fourth gear and the third gear respectively; the toggle assembly is respectively matched with the third gear and the closing member;

the sliding block is in sliding fit with the side wall of the circulating pipe, the sliding block is in an inverted cone shape along the water flow direction, and the conical surface of the sliding block is in contact with the end part of the sliding rod.

The invention provides an overcurrent cutoff device which can automatically cut off a tap water pipe when a set amount of terminal water flow flows out, and avoid overflow of water flow, thereby avoiding waste of water resources and avoiding damage to floors, furniture, circuits and the like.

The runner pipe is connected on the water pipe, and when water flows through the runner pipe, the water flows scour the impeller to rotate the impeller, so that the first gear, the second gear and the fourth gear are sequentially driven to rotate. When rivers passed through the sliding block, can extrude the sliding block, made the sliding block slide in the circulation pipe, the conical surface extrusion slide bar of sliding block to make the fifth gear respectively with fourth gear and third gear engagement, thereby drive the third gear and rotate, third gear rotates after the certain time, can drive and stir subassembly work, thereby drive closure work, realize cuting of rivers. The impeller is continuously flushed by water flow, so that the third gear is continuously driven to rotate, the flow of the water flow has a corresponding relation with the rotation time of the third gear, and the water flow can be cut off after a certain amount of water flows out of the terminal water flow by adjusting the time from the beginning of rotation of the third gear to the driving of the toggle assembly, so that the water flow is prevented from overflowing.

Further, the coupling assembly further comprises a limiting member arranged inside the mounting block; be equipped with the dog on the slide bar, the slide bar is arranged one end and locating part sliding fit in the installation piece in, and the slide bar cover is equipped with first spring and the both ends of first spring contact with locating part and dog respectively.

The sliding rod moves under the pushing of the sliding block, so that the sliding rod can also slide in the limiting piece, meanwhile, the spring is compressed, and after the closing piece cuts off water flow, the sliding rod slides reversely under the action of the spring force, so that the fifth gear is separated from the fourth gear and the third gear, and the reset of the fifth gear is realized.

Further, the fifth gear is a bevel gear.

The fifth gear is in the form of a bevel gear for simultaneous engagement with the fourth and third gears.

Furthermore, the third gear is provided with a shifting block; the poking assembly comprises a turning piece and a rotating rod; the overturning part comprises a top pressing block and a clamping block which are connected with each other; the top pressing block is matched with the shifting block, and the connecting position of the top pressing block and the clamping block is rotationally connected with the mounting block through a first rotating shaft; the dwang cooperatees with the closure piece, and the one end of dwang passes through second pivot and installation piece swivelling joint, and the other end and the fixture block of dwang are connected, and the position that dwang and installation piece are connected is equipped with face vortex spring or torsional spring.

The shifting block can rotate along with the rotation of the third gear, after the third gear rotates for a certain time, the shifting block can be in contact with the jacking block and extrude the jacking block, the jacking block rotates around the first rotating shaft, the clamping block is separated from the rotating rod, and the rotating rod rotates under the action of an -surface vortex spring or a torsion spring, so that the closing member is driven to cut off water flow.

Furthermore, the toggle assembly further comprises a second spring, and two ends of the second spring are respectively connected with the jacking block and the mounting block.

And in the rotating process of the top pressing block, the second spring is compressed or extruded to generate elasticity, and the top pressing block is reset by the second spring after the top pressing block is separated from the shifting block.
