Abstract
The utility model belongs to the technical field of valves and particularly relates to an anti-loose ceramic valve core. The anti-loose ceramic valve core comprises a valve core shell and a valve rod, wherein the valve rod is rotatablely connected onto the valve core shell. The anti-loose ceramic valve core is characterized in that the upper end of the valve rod extends out of the valve core shell; the side face of the upper end of the valve rod is a conical face; conical teeth are formed on the conical face; the top face of the upper end of the valve rod is provided with a threaded hole; the threaded hole is matched with a fastening screw on a faucet switch; the faucet switch and the valve rod are fixedly connected into a whole by the fastening screw; and the conical face of the end part of the valve rod extends into the hole of the faucet switch. The tighter the fastening screw is, the tighter the connection between the conical face of the end part of the valve rod as well as the conical teeth on the conical face and the faucet switch, and therefore, the connection stability between the faucet switch and the valve rod is enhanced.
Description
Technical field
The utility model belongs to valve technology field, refers in particular to a kind of locking ceramic valve core.
Background technique
When existing ceramic valve core is loaded in the water tap, be connected by fastening screw between valve rod and the water tap, after water tap uses a period of time, fastening screw easily occurs loosening, thereby cause cooperating between water tap and the valve rod not tight, and water tap is installed the position, hole of fastening screw and usually the decorations such as plate with trademark is bonded at and carries out processing attractive in appearance on the position, hole, again screw fastening screw and then must tear the decorations such as plate with trademark, the decorations such as plate with trademark are disposable, cause water tap aesthetic disappearance, the combination of being badly in need of a kind of valve rod and water tap on the market is spool more closely.
Summary of the invention
The purpose of this utility model is to provide a kind of making simple, and the combination of quick, the safe and reliable and water tap of moulding is locking ceramic valve core more closely.
For achieving the above object, the utility model provides following technological scheme: a kind of locking ceramic valve core, comprise spool housing and the valve rod that is rotatably connected on the spool housing, the spool housing is stretched out in the upper end of described valve rod, the side of valve rod upper end is the conical surface, form the cone tooth on the conical surface, the end face of valve rod upper end is provided with tapped hole.
The lower end of above-mentioned valve rod is connected with the moving valve plate that pottery is made, and the downside of moving valve plate is provided with fixed valve plate, and fixed valve plate is fixed in the spool housing by sealing gasket.
The utility model beneficial effect compared to existing technology is: the utility model comprises spool housing and the valve rod that is rotatably connected on the spool housing, the spool housing is stretched out in the upper end of valve rod, the side of valve rod upper end is the conical surface, form the cone tooth on the conical surface, the end face of valve rod upper end is provided with tapped hole, the tapped hole cooperation at fastening screw and valve rod top is fixed with one water tap and valve rod, the conical surface of valve rod end stretches in the hole of water tap, fastening screw is tighter, the conical surface of valve rod end and cone tooth and the water tap on the conical surface are tightr, have improved the stability that water tap is connected with valve rod.
Description of drawings
Fig. 1 is plan view of the present utility model.
Fig. 2 is left view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-2, a kind of locking ceramic valve core comprises spool housing 3 and the valve rod 1 that is rotatably connected on the spool housing 3, spool housing 3 is stretched out in the upper end of described valve rod 1, the side of valve rod 1 upper end is the conical surface 12, forms the cone tooth on the conical surface 12, and the end face of valve rod 1 upper end is provided with tapped hole 11.
Tapped hole 11 cooperations at fastening screw and valve rod 1 top are fixed with one water tap and valve rod 1, the conical surface 12 of valve rod 1 end stretches in the hole of water tap, fastening screw is tighter, the conical surface 12 and cone tooth and the water tap on the conical surface of valve rod 1 end be tightr, improved water tap and has been connected the stability that connects with valve rod.
The lower end of above-mentioned valve rod 1 is connected with the moving valve plate that pottery is made, and the downside of moving valve plate is provided with fixed valve plate, and fixed valve plate is fixed in the spool housing 3 by sealing gasket 4.The middle part of spool housing 3 is set with O shape circle 2.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
