Abstract
The utility model discloses a nose of a dental handpiece. The nose consists of a nose cover, a resilient sheet, a rubber sleeve, bearings, a center spindle, a wind wheel and a nose body. The nose is characterized in that the surface of the rubber sleeve is in a concave-convex shape, a sealing edge is arranged on the outer side of the rubber sleeve, the rubber sleeve wraps the outer side surfaces of the bearings and the resilience sheet, and the surface area of the bearing wrapped by the rubber sleeve is one third or more of the surface area of the bearing. The nose is simple in production structure, low in cost, less in vibration, and low in noise when being used.
Description
Technical field
This utility model relates to the dental instruments field, relates in particular to a kind of head of dental handpiece.
Background technology
In the middle of the present existing technology; The inner bearing of dental handpiece head all is that the shell fragment that the rubber ring that is provided with through head lid and handpiece body inner wall groove position and bottom surface are provided with is controlled its peripheral vibration, thus the control bearing up and down with front and back owing to vibrate the displacement that causes.This dental handpiece; Though can control the bear vibration and the displacement of head inside to a certain extent; Because rubber ring can only encase the very little part of bearing; Bearing still has corresponding vibration and displacement space, so the noise of bearing vibration and vibration still can have influence on the use of dental handpiece.
Summary of the invention
The purpose of this utility model is to provide a kind of head of dental handpiece, and its production structure is simple, cost is low, vibration reduces, use noise low.
For realizing above-mentioned purpose; The technical solution of this utility model is: a kind of head of dental handpiece; Comprise: head lid, shell fragment, rubber sleeve, bearing, central shaft, wind wheel, handpiece body; It is characterized in that: described rubber sleeve surface concave-convex surface, the limit is sealed in the described rubber sleeve outside, and described rubber sleeve encases the lateral surface and the shell fragment of bearing;
Optional, the surface area that described rubber sleeve encases bearing be the bearing surface area 1/3rd or more than;
Optional, described rubber sleeve encases all surfaces of bearing.
The beneficial effect of this utility model is: the head of the existing dental handpiece of contrast existing market; The area that rubber sleeve in this utility model head encases bearing surface is bigger, makes the periphery vibration of bearing reduce, and the rubber sleeve outside is provided with the edge sealing mouth and directly contacts handpiece body and head lid bottom surface; Make the porpoise of bearing reduce; Remove original groove position, handpiece body and head lid the inside simultaneously, processing technique is simpler, processing cost is lower, the vibration is littler, uses noise lower.

Fig. 2 is the combinative structure sketch map of this utility model;
Among the figure: 1-head lid, 2-shell fragment, 3-bearing holder (housing, cover), 4-bearing, 5-central shaft, 6-wind wheel, 7-handpiece body.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of this utility model is done further explain.
Referring to accompanying drawing 1; This utility model comprises that head lid, rubber sleeve, bearing, central shaft, wind wheel, handpiece body constitute; Central shaft passes the wind wheel center and is fixed together; Central shaft passes bearing and is fixed together, the area that the rubber sleeve interference encases bearing surface be 1/3rd or more than, described rubber sleeve encases the lateral surface and the shell fragment of bearing simultaneously;
Referring to accompanying drawing 2, central shaft is installed in vivo, shell fragment is installed in the head lid end, the head cap seal is lived handpiece body then.
