The fire plug of said structure form because the operative end at its upper valve rod top closed by outside envelope, and pinned by the axial limiting structure again between outside envelope and stopper, can not be removed.Under the situation of non-use, though remained the transmission matching relationship between the interior drive mechanism body of ferrous material and upper valve rod, and also be provided with between outside envelope and interior drive mechanism body and can make the drive mechanism that cooperatively interacts, but can make it enter/break away from the required displacement fit clearance of transmission cooperation owing to maintain between the outside envelope axial abutting end relative with interior drive mechanism body, the drive mechanism body is done axial upper and lower displacement in allowing in this fit clearance scope.When interior drive mechanism body places on the upper valve rod top in self gravitation effect whereabouts, just be in the state of maximum fit clearance between itself and the outside envelope, on drive connection, also promptly be in and broken away from the state that transmission cooperates, even therefore pull this outside envelope, drive mechanism body and upper valve rod rotate in also can't making, thereby also just can't open the valve of fire plug.When needs open and close operation to fire plug, the corresponding tool that only need will have magnetic material places the end of outside envelope, the interior drive mechanism body of ferrous material moves outwardly and into the transmission mated condition with outside envelope under the magnetive attraction effect, this moment by pull outside envelope can be in drive mechanism drives the drive mechanism body and and then drive upper valve rod and rotate, realize the keying of fire plug is operated.Take this special tool away, interior transmission body falls under action of gravity again, makes itself and outside envelope also break away from the transmission matching relationship.
In above-mentioned structure, the transmission fit structure at drive mechanism body and upper valve rod top can have the multiple choices form in said being somebody's turn to do.For example, can be to have and to open and close the operating side with the polymorphic structure of square or other form at upper valve rod top and remain the cover type structure that transmission cooperates the required form internal perisporium, also can be to have to open and close between the end face of operating side with the polymorphic structure at upper valve rod top and remain the single or multiple latching structures of axially stretching slotting formula that transmission cooperates, multi-form transmission fit structure can also be united use etc. mutually.
In the said structure, the said axial limiting structure that between outside envelope and stopper, is provided with, can adopt different on only being limited in axially activity and need not to limit the position limiting structure that radially rotates, wherein comparatively easy mode, what can be adopted as cooperatively interacting of being provided with between it cooperates side face radially stretches male structure and corresponding indent limited ring groove structure, makes this outside envelope can do that the original place is freely rotated but can't be removed.
As above-mentioned, in the encrypted antitheft fire plug structure of the present utility model, between the inboard and interior drive mechanism body of said outside envelope, and between interior drive mechanism body and keying operating side, upper valve rod top, all be provided with corresponding drive mechanism respectively, these drive mechanisms both can adopt the structure of same form, as all being adopted as the special-shaped socket joint type drive mechanism of same form, also can being adopted as difform special-shaped socket joint type drive mechanism or being respectively multi-form drive mechanisms such as latching formula and special-shaped socket joint type.
Be adopted as the fire plug that non-perpendicular shape is provided with for upper valve rod, be difficult under action of gravity, fall naturally and realize cooperating along its interior drive mechanism body that axially is provided with in the said structure with outside envelope disengaging transmission, for this reason, on the basis of above-mentioned knot, can between the axial abutting end of said outside envelope and interior drive mechanism body, be provided with and it is kept break away from transmission and cooperates the Flexible Reset structure of the appropriate formats such as back-moving spring of position get final product, and its elastic reset power obviously is should be less than making it enter the magnetic action power of the corresponding special tool of transmission cooperation.
Be appreciated that thus, the fire plug of the utility model said structure is simple in structure, and can only carry out on/off operation with special tool by the related personnel, prevented from effectively arbitrarily to be operated by the people, guarantee the normal use of fire plug, also prevent the loss of water resource, eliminated this hidden danger in the present fire fighting system.
Below, foregoing of the present utility model is described in further detail again by the specific embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
