the setting of town road Outdoor Fire Hydrant and use are the requisite municipal fire fighting devicies in any one city, general town road all can arrange a fire plug every certain distance, and a fire plug water supply control valve door vertical shaft is set nearby, so that the staff regularly carries out examination and maintenance to fire plug, the normal use of described fire plug all is provided with water gauge tap processed and water outlet connector, described its well head of water supply control valve door vertical shaft all is provided with a crib, form the cavity of an accommodating well lid on described crib, described well lid is placed in the indication cavity, in city, municipal fire plug like this and water supply control valve door vertical shaft are found everywhere, when the municipal administration staff carries out examination and maintenance to fire plug, at first handy special tool is opened fire plug water gauge tap processed, and the water outlet connector is checked, when need to safeguarding, fire plug need close fire plug water supply control valve door, thereby the staff need open the vertical shaft well lid simultaneously before valve-off, in the prior art, the municipal administration staff opens the fire plug switch and all adopts fire plug operation special tool, described fire plug operation special tool refers to the operation wrench with fire plug water gauge tap processed and water outlet connector, the staff utilizes the dedicated operations wrench of indication to open and close operation to fire plug water system and water outlet connector.when opening fire plug water supply control valve door vertical shaft well lid, municipal administration staff instrument the most commonly used is pull bar, described pull bar comprises holding rod and drag hook, described drag hook is connected in the end of holding rod, during work, the staff holds holding rod, and with drag hook, hook pulling eye on well lid, then well lid is pulled up and moves apart well head, the problem that prior art exists is, in many cases, because fire plug is not opened for a long time, because causing fire plug water gauge tap processed and stuck being difficult to of water outlet connector screw thread, corrosion opens, need to add loop bar and extend power arm length on the power arm of operation wrench, or with hammer, beat vibration, just can open the fire plug switch, and the fire plug examination and maintenance often need be opened the vertical shaft well lid of fire plug water supply control valve door.Like this, the every subjob of staff needs in the situation of the instruments such as while fire plug switching manipulation wrench going along with, loop bar, hammer, drag hook, could bring inconvenience for staff's operation to the unlatching of fire plug switch or the operation of closing, obviously prior art has further improved necessity.Problem for the prior art existence, the inventor is on the basis of the disclosed well cover opening device of former utility model patent CN201120161007.3, develop a kind of fire plug of effort-saving with well lid drag hook water action bars processed, its application comprises fire plug switching manipulation wrench, the built-in loop bar of power arm, drag hook, hammer at least in one, and the utility model is the further improvement and perfection to the disclosed technical scheme of former utility model patent CN201120161007.3 patent.
Summary of the invention
The purpose of this utility model is to provide a kind of fire plug of effort-saving with the well lid drag hook water action bars processed, the problem that exists to solve prior art.
A kind of fire plug of effort-saving with well lid drag hook water of the present utility model action bars processed, comprise holding rod, it is characterized in that described holding rod termination is installed with the disc of a width greater than the holding rod diameter, described disc comprises upper side edge and lower side, be connected with a crotch that bends inwards on described lower side, also be connected with simultaneously for the interior angle sleeve of fire plug water open and close processed on described disc and/or be formed with the stiff prong that operates for the water outlet connector.
As preferably, the width of described disc upper side edge is greater than the width of lower side, is convenient to like this upper side edge and uses when hammer.
As preferably, the axis of described interior angle sleeve is perpendicular to the card of disc, and described stiff prong is formed on the outboard end of disc.
As further improving, described holding rod is hollow section, also comprises addition rod, described addition rod is plugged in described holding rod, addition rod can be pulled out from holding rod so where necessary, holding rod and addition rod form power arm jointly like this, and obviously this will be more laborsaving.
This fire plug of effort-saving with well lid drag hook water of the present utility model action bars processed, due to it with the interior angle sleeve and/or be used for the stiff prong of water outlet connector operation, can open or close fire plug water system and water outlet connector with it for this reason, during use, the staff pulls out loop bar on the action bars power arm to extend power arm length, can very laborsaving operation fire plug water gauge tap processed and the keying of water outlet connector; Simultaneously, the utility model is with the well lid drag hook, can be used for opening the vertical shaft well lid, during use, the staff holds holding rod, and crotch is inserted in hook hole on well lid, then mentions, the pivot of well lid and crib is equivalent to the fulcrum of a lever at this moment, the power arm that the length that well lid adds holding rod is equivalent to lever,, due to the effect of lever, obviously can get up manhole cover lifting easily.Thereby need not carry separately other auxiliary tools, very convenient, obviously the purpose of this utility model is achieved again.
