The leakage-proof float ball switching structure comprises a float ball assembly and a switching assembly; the float ball assembly is arranged on the switching assembly through a rotating shaft; the switching assembly comprises an external float ball flange head; a cylindrical cavity of which both sides are open is arranged in the float ball flange head; the side wall of the cylindrical cavity is provided with an internal screw thread; the bottom surface inside the cylindrical cavity is provided with a sealing cap contacted with the float ball assembly; a float ball big stud is arranged in the cylindrical cavity; a stepping float ball inner shaft is sleeved in the float ball big stud; and the stepping float ball inner shaft is connected with a microswitch. According to the leakage-proof float ball switching structure disclosed by the utility model, by adopting the sealing cap and the screw thread fit of the float ball flange head and an internal device in the switching assembly, the switching assembly is in a sealed environment in the working process, the unsmoothness of movement of parts is prevented, the smooth movement of the parts is ensured and the service life of products is prolonged.
Description
Technical field
The utility model relates to a kind of construction of switch, especially a kind of leakproof float switch structure with good sealing property.
Technical background
Float switch is a kind of construction of switch of in nearly water environment, using always, and it answers the height of the water surface through a ballottement, thereby carries out the on-off action of switch; Perhaps produce signal, existing float switch generally comprises a ball float and reaches the switch module that is connected transmission with this ball float, and perhaps works in the wet environment in the water owing to float switch is in for a long time; And existing float switch is not provided with leakage-proof structure; Water or steam can get in the switch module easily, become unsmooth thereby cause easily to move each other between parts in the switch module, are unfavorable for the ride comfort that switch module is movable; Cause the damage or the inefficacy of parts easily, shortened the useful life of product.
Summary of the invention
But the utility model provides a kind of long-term smoothness run of holding member, prolongs the product leakproof float switch structure in useful life.
To achieve these goals, the utility model adopts following technical scheme:
It comprises ball float assembly and switch module; Described ball float assembly is installed on the switch module through a rotating shaft; Its improvement is: described switch module comprises outside ball float flange head, is provided with the cylindrical cavity of both-side opening in the described ball float flange head, and described cylindrical cavity sidewall is provided with internal thread; The inside bottom surface place of cylindrical cavity is provided with the sealing cap that contacts with the ball float assembly; The big double-screw bolt of ball float is installed in the described cylindrical cavity, is arranged with the floating axis bulbi internus of a stepping in the big double-screw bolt of ball float, floating axis bulbi internus connects a sensitive switch.
Preferably, be provided with a boss with the ball float position contacting on the described sealing cap.
Preferably, described sensitive switch is installed on the big double-screw bolt of ball float through a switch bracket.
Preferably, described ball float assembly comprises a ball float, and described ball float connects an end of a crank, and the other end of crank is installed on the stepping ball float flange head through rotating shaft, and described crank end also is provided with the trigger end of swing back contact seal cap.
Preferably, described ball float is connected in crank one end through the stainless steel nut, and the joint face of described ball float and stainless steel nut is provided with the stainless steel ball card.
Preferably, described sealing cap is a silicon rubber cup.
Owing to adopted said structure; The leakproof float switch structure of the utility model is provided with a sealing cap in the contact position of ball float assembly and switch module, prevented that liquids and gases get in the switch module in the course of work, and the cylindrical cavity sidewall of ball float flange head is provided with internal thread in the switch module; Pass through threaded engagement with internal components; Further improve the sealing of product, be in the environment of a sealing when making switch module work, prevented the unsmooth of component movement; Ensure the smooth motion of parts, prolonged the useful life of product.
