Description
Technical field
This utility model belongs to the dental handpiece technical field, is specifically related to a kind of dental handpiece hydraulic quick coupler of the scalable water yield.
Background technology
The dental handpiece kind is more, can be divided into high speed handpiece and low speed mobile phone according to rotating speed and structure, and wherein high speed handpiece utilizes the miniature turbine in the high pressure air drives mobile phone head, and secondary speed can reach 30-50 ten thousand r/min, and the cutting linear velocity of car pin can reach 15m/s.
At present the dental handpiece that generally uses is mainly formed by handle, head and at the fast joint that is connected handle and head between handle and the head; This dental handpiece can not be regulated the spray water flow according to actual needs in each operation, can't effectively control tooth and clean and refrigerative effect.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of dental handpiece hydraulic quick coupler of the scalable water yield, can regulate discharge to realize dental handpiece as required when treating, and effectively controls tooth and cleans and refrigerative effect.
For addressing the above problem, the technical scheme that this utility model adopted is as follows:
A kind of dental handpiece hydraulic quick coupler of the scalable water yield comprises the fast joint body, and described joint body inside is provided with water inlet pipe and water-supply-pipe, and an end of water inlet pipe connects water-supply-pipe; Described fast joint body is provided with a plunger shaft, and the bottom of plunger shaft is provided with a through hole that is complementary with piston, and piston is installed in the plunger shaft, and its upper end cooperates with plunger shaft, and the lower end can be stretched in the water-supply-pipe by through hole; Socket one spring on the piston, spring one end are fixed on the plunger shaft bottom, and the other end is fixed on piston top; The top of piston is provided with to lower recess one arc groove, places a steel ball in the arc groove, and overcoat is regulated in socket one on the fast joint body of piston outside, and is provided with an eccentric groove along circumferencial direction in the adjusting overcoat of steel ball contact position.
In order to reach the purpose of controlling the water yield in the water-supply-pipe of flowing through, in a kind of preferred scheme of the present utility model, the eccentric groove that described adjusting puts outward; When steel ball is positioned at the eccentric groove at highly minimum place, piston is pressed into bottom the water-supply-pipe.
In order to realize good sealing effectiveness, prevent that the water in the water-supply-pipe from spilling, in a kind of preferred scheme of the present utility model, the top of described piston is provided with an annular groove, is with a sealing ring in the groove, the sealing ring outside and plunger shaft wall interference fit.
Compared to existing technology, the beneficial effects of the utility model are: the dental handpiece hydraulic quick coupler of the scalable water yield described in the utility model can realize that dental handpiece the time can regulate discharge as required in treatment, effectively controls tooth and cleans and refrigerative effect.Further, this utility model can also reach the purpose of the control water yield.
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the dental handpiece hydraulic quick coupler of the scalable water yield described in the utility model;
Fig. 2 is the footpath F-F cutaway view of the dental handpiece fast joint of the scalable water yield described in the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the dental handpiece hydraulic quick coupler of the scalable water yield described in the utility model comprises fast joint body 6, and described joint body 6 inside are provided with water inlet pipe 7 and water-supply-pipe 8, and an end of water inlet pipe 7 connects water-supply-pipe 8; Described fast joint body 6 is provided with a plunger shaft, and the bottom of plunger shaft is provided with a through hole that is complementary with piston 1, and piston 1 is installed in the plunger shaft, and its upper end cooperates with plunger shaft, and the lower end can be stretched in the water-supply-pipe 8 by through hole; Socket one spring 2 on the piston 1, spring 2 one ends are fixed on the plunger shaft bottom, and the other end is fixed on piston 1 top; The top of piston 1 is provided with to lower recess one arc groove, places a steel ball 4 in the arc groove, and overcoat 5 is regulated in socket one on the fast joint body 6 of piston 1 outside, and is provided with an eccentric groove along circumferencial direction in the adjusting overcoat 5 of steel ball 4 contact positions.When needing to regulate discharge, rotate and regulate overcoat 5, when the groove on regulating overcoat 5 turned on the steel ball 4, the first half of steel ball 4 was arranged in groove, and piston 1 is got back in the plunger shaft, and water-supply-pipe 8 is opened fully; When the most shallow eccentric groove on regulating overcoat 5 turned on the steel ball 4, piston 1 was extruded and stretches into from through hole in the water-supply-pipe 8, closes water-supply-pipe 8.
In order to reach the purpose of controlling the water yield in the water-supply-pipe 8 of flowing through, in a kind of preferred scheme of the present utility model, the eccentric groove on the described adjusting overcoat 5; When steel ball 4 is positioned at the highly the most shallow eccentric groove, piston 1 is pressed into the water-supply-pipe bottom.This utility model in use, rotate to regulate overcoat 5, because eccentric groove is by even from depth to shallow a groove, when steel ball 4 is positioned at eccentric groove diverse location, the degree of depth that piston is pressed in the water-supply-pipe is also inequality, thus reach the water yield of controlling in the water-supply-pipe.
In order to realize good sealing effectiveness, prevent that the water in the water-supply-pipe 8 from spilling, in a kind of preferred scheme of the present utility model, the top of described piston 1 is provided with an annular groove, be with a sealing ring 3 in the groove, sealing ring 3 outsides and plunger shaft wall interference fit.
Above-mentioned embodiment only is a preferred implementation of the present utility model; can not limit the scope of this utility model protection with this, the variation of any unsubstantiality that those skilled in the art is done on basis of the present utility model and replacement all belong to this utility model scope required for protection.
