Abstract
The utility model discloses a pressing shaft of a dental handpiece. The pressing shaft is characterized in that a locating sleeve is arranged outside the clamping head; a clamping column on the clamping head is provided with a chamfer; concave-convex textures are formed inside the clamping column of the clamping head; furthermore, the concave-convex textures are in a chute shape or screw shape; the top and bottom of a spring are in a horizontal plane state. Through the arrangement of the locating sleeve outside the clamping head, the clamping column on the clamping head can be effectively protected, the deformation of the clamping column due to outward tension in the using process can be avoided; through arranging a full angle on the clamping column of the clamping head, the insertion and the installation of a machine needle and the installation of the locating sleeve can become convenient; through the arrangement of the concave-convex textures inside the clamping column, the looseness and the slipping of the machine needle can be effectively prevented. The pressing shaft of the dental handpiece has good steadiness, long service life, and convenience for installation and maintenance.
Description
Technical field
This utility model relates to the dental instruments field, relate in particular to a kind of dental handpiece by last item.
Background technology
Toothwash, dental filling, grind one's teeth in sleep more and more commonly at our daily life, people make up the different defectives of tooth in this way, satisfy beauty treatment and reparation to tooth.a kind of dental instruments the most commonly used in the middle of dentist mechanism is exactly dental handpiece, the modal kind of dental handpiece is divided into mobile phone and high speed handpiece at a slow speed, mobile phone is mainly used to tooth is cleaned at a slow speed, polishing, high speed handpiece is to be used for clinically the incisal grinding tooth, mobile phone or high speed handpiece at a slow speed, no matter be the sort of dental handpiece, the get on the bus rotating speed of pin of its head is all very high, wherein the car pin by a kind of press by last item fixing, after using the regular hour, the car pin is because often friction is easily loosening, skid, and by in last item also due to the outside tension force of its car pin easily occur the distortion.
In order to solve this present situation, the special last item of pressing of researching and developing a kind of dental handpiece by the innovative design of its structure, improves it by the firm performance of last item, extends the service life of pressing last item.
Summary of the invention
The purpose of this utility model be to provide a kind of dental handpiece by last item, by the coordinate mounting structure of novel chuck with positioning sleeve, make this utility model easier for installation by last item, firm performance is stronger, longer service life, the becoming flexible, skidding and metaboly by last item inside of effectively having avoided dental handpiece to use causing for a long time.
For achieving the above object, technical solution of the present utility model is: a kind of dental handpiece press last item, comprising: fixed cover, spring, positioning sleeve, chuck, overcoat, it is characterized in that: described chuck outer setting has positioning sleeve, clamp column on described chuck is provided with chamfering, and the clamp column inside on described chuck is provided with Z-Correct bump mapping Z-correct, further, described Z-Correct bump mapping Z-correct is tongue and groove shape or concavo-convex screw-like, and described spring top and bottom are made as horizontal plane.
the beneficial effects of the utility model are: a kind of dental handpiece press last item, solve becoming flexible by the inner easily appearance of last item of dental handpiece in the market, skid and metaboly, by the chuck outer setting, positioning sleeve is arranged, effectively protect the clamp column on chuck, avoid the distortion that in use procedure, clamp column causes because of outside tension force, be provided with full-shape by the chuck clamp column, facilitate the insertion installation of carriage return pin and the installation of positioning sleeve, be provided with Z-Correct bump mapping Z-correct by chuck clamp column inside, can imitate to prevent that car pin in use procedure from easily occurring loosening, the phenomenon such as skid.This utility model dental handpiece possess better firm performance, longer service life by last item, its installation simultaneously and keep in repair convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-fixed cover, 2-spring, 3-positioning sleeve, 4-chuck, 41-clamp column, 42-chamfering, 43-Z-Correct bump mapping Z-correct, 5-overcoat.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
referring to accompanying drawing 1, this utility model: a kind of dental handpiece press last item, comprise: fixed cover, spring, positioning sleeve, chuck, overcoat, its chuck outer setting has positioning sleeve, the clamp column on its chuck of wrapping by positioning sleeve, thereby prevent from causing the loosening of clamp column and car pin because car pin high-speed rotation causes outside tension force in use procedure, its clamp column is provided with chamfering, when inserting the installation car pin, its chamfering can play effective importing effect of car pin, when positioning sleeve is installed, its chamfering also can play effective importing effect of positioning sleeve, clamp column inside on its chuck is provided with Z-Correct bump mapping Z-correct, further, its Z-Correct bump mapping Z-correct is tongue and groove shape or concavo-convex screw-like, these Z-Correct bump mapping Z-correct effectively strengthen clamp column on chuck and the interaction force between the car pin, the firm performance of enhancement, top and the bottom of its spring are made as horizontal plane, vertical stressed top and the bottom at spring of its spring of assurance that this kind structure can be imitated is more even, more stable.
