Abstract
The invention discloses a water nozzle easy to assemble. The water nozzle comprises a valve body, a valve cover arranged at the upper end of the valve body, a fixed ceramic piece, a moving ceramic piece, a valve rod and a fixed three-jaw, wherein the fixed ceramic piece, the moving ceramic piece and the valve rod are arranged inside the valve body from bottom to top; the fixed three-jaw sleeves the valve rod and is used for fixing the valve rod inside the valve body; the fixed three-jaw takes the shape of a ring of which two ends are opened; three bayonets are formed in the outer walls of the fixed three-jaw, correspond to a boss which extends towards the center of the valve body on the inner wall of the valve body and are uniformly distributed in the circumferential direction of the fixed three-jaw; the boss is clamped into any one bayonet; annular fixing steps which are arranged in an inserting groove between the valve rod and the valve body and are coaxial are formed in the bottom of the fixed three-jaw; the outer diameters of the annular fixed steps are smaller than that of the fixed three-jaw. Any bayonet in the valve rod is assembled with the boss inside the valve body, so that the assembling position of the valve rod is changed into three from the conventional one, the valve rod is convenient to mount and fix, and the assembling efficiency of operators is multiplied.
Description
Technical field
The present invention relates to a kind of ceramic valve core water nozzle, be specifically related to a kind of water nozzle being easy to assemble.
Background technique
Existing ceramic valve core water nozzle, comprises valve body, is arranged at the valve gap of valve body upper end, is arranged at the definite ceramic chip in valve body, dynamic porcelain piece and valve rod from below to up, and is enclosed within the outer fixing three-jaw be fixed on by valve rod in valve body of valve rod.Described fixing three-jaw is the toroidal of both ends open, and also offer 1 along bayonet socket at the outer wall of fixing three-jaw, this bayonet socket is corresponding with the boss in valve body, when mounted, bayonet socket aims at the boss in valve body, is pressed in valve body, is fixed tightly in fixing three-jaw in valve body by valve rod.This design only has an aligned position due to the boss in fixing three-jaw and valve body, also namely only has unique mounting point, when mounted, alignment precision requires high, and not only installation rate is slow, manufacturing efficiency is low, and offsets a little as position, then extruding is produced to valve body, destroy valve body.Valve rod and valve body, connection between valve rod and valve gap are firm not in addition, and during use, valve rod rotates under the drive of valve gap, rocking of valve rod can be caused, increase the stressed of valve rod, cause valve rod to be easy to fracture, the permeable hole on definite ceramic chip cannot be closed with dynamic porcelain piece, cause water nozzle to leak.
Summary of the invention
Technical problem to be solved by this invention is to provide the water nozzle being easy to assemble that a kind of stabilized structure, installation rate are fast, manufacturing efficiency is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Be easy to the water nozzle assembled, comprise valve body, be arranged at the valve gap of valve body upper end, be arranged at the definite ceramic chip in valve body, dynamic porcelain piece and valve rod from below to up, and be enclosed within the outer fixing three-jaw be fixed on by valve rod in valve body of valve rod; Described fixing three-jaw is the toroidal of both ends open, offer bayonet socket at the outer wall of fixing three-jaw, this bayonet socket is corresponding with the boss extended to valve body center of valve interior wall, and described bayonet socket is 3, circumference along fixing three-jaw is uniformly distributed, and described boss snaps in arbitrary bayonet socket; The annular of the coaxial line that the bottom of described fixing three-jaw is provided with in the slot that is placed between valve rod and valve body fixes step, and the external diameter of the fixing step of this annular is less than the external diameter of fixing three-jaw.
In order to the difficulty of the intensity and installation of taking into account fixing three-jaw, described bayonet socket is wide can be 2mm.
In order to make the boss in valve body easierly can snap in bayonet socket on fixing three-jaw, and connect compact, the cross section of the boss in described valve body can be semicircle, and its radius can be 0.9mm.
Such scheme is preferred, and the top of described fixing three-jaw can be provided with and upwards be extended with 3 crotches, and this crotch snaps in the positioning block bottom be provided with in valve body, moves to prevent on fixing three-jaw.
Such scheme is preferred, and described crotch can be evenly distributed on fixing three-jaw, and the bayonet socket that staggers.
Such scheme is preferred, and described each crotch can be distributed on the perpendicular bisector of 2 bayonet sockets be adjacent.
Compared with prior art, fixing three-jaw of the present invention is being distributed with bayonet socket along its circumference, bayonet socket matches with the boss in valve body, fixing three-jaw is made firmly to be fixed in valve body by valve rod, and bayonet sockets all on fixing three-jaw all with distribute, the arbitrary bayonet socket on fixing three-jaw can be assembled with the boss in valve body, makes the rigging position of fixing three-jaw become three from original one, be convenient to install and fix, the efficiency of assembling of workman obtains and increases exponentially; In addition because crotch snaps in the positioning block bottom be provided with in valve body, make valve rod and valve body, fixing three-jaw and valve rod and valve body connection more compact, firm, during rotation, valve rod is stressed little, extends working life.
