CN205234664U - Prevent dental handpiece aircraft nose of resorption - Google Patents

Abstract

The utility model discloses a prevent dental handpiece aircraft nose of resorption, its characterized in that: the resorption pad of preventing adopt inside outside bellied skilful ramp type's shape design structure, the resorption pad of preventing adopt that rubber is integrative to take shape. Because the resorption pad of preventing that the aircraft nose is inside adopts inside outside bellied skilful ramp type's shape design structure, and it is integrative shaping to adopt rubber, when the dental handpiece stop work, prevent the outside bulge in inside of resorption pad can be effectual with press the off -axial cover and produce closely friction, effectively prevent the phenomenon of atmospheric pressure resorption, this kind of friction of while also can effectively be shortened the rotatory back of pressing off -axial cover and car needle and continue the time of changeing owing to inertia, prevent to press down the rotatory back of off -axial cover and car needle after dental handpiece from stopping because the injury to the oral cavity is sent in the continuous transduction of inertia. The utility model discloses prevent dental handpiece aircraft nose of resorption is zero resorption phenomenon almost, effectively improves the atmospheric pressure energy transformation ratio in the aircraft nose, improves the life of aircraft nose and cell -phone.

Description

A kind of dental handpiece heads of anti-resorption

Technical field

The utility model relates to medical instruments field, relates in particular to the dental handpiece heads of a kind of anti-resorption in dental appliance field.

Background technology

Toothwash, dental filling, grind one's teeth in sleep more and more commonly in our daily life, people make up the different defects of tooth in this way, meet beauty treatment and reparation to tooth. A kind of dental appliance the most conventional in the middle of dentist mechanism is exactly dental handpiece.

In dental handpiece heads, the rotation of car pin is a power conversion that converts impeller and the rotation of car pin by air pressure to, air pressure is the source of energy, but all more or less there is a kind of air pressure resorption phenomenon in the setting of dental handpiece heads inside in the market, because easily causing mouth cavity liquid etc., the resorption of air pressure is reversed into head and cell-phone handle inside, thereby cause the various damages to head and interior of mobile phone, also reduced the energy transformation ratio of air pressure simultaneously.

Utility model content

The purpose of this utility model is to solve above-mentioned present situation, and spy researches and develops a kind of dental handpiece heads of anti-resorption, adopts the almost zero resorption phenomenon of dental handpiece of this kind of head, effectively improves the air pressure energy transformation ratio in head, improves the service life of head and mobile phone.

For achieving the above object, technical solution of the present utility model is: a kind of dental handpiece heads of anti-resorption, comprise: crosshead body, wind wheel, o type circle (a), packing ring, bearing, car pin, press outer shaft sleeve, anti-resorption pad, press rear end cap, cover base after head, head bearing holder (housing, cover), spring, press bonnet, waveform splinter, bearing, o type circle (b), the assemble method of its each parts is with consistent in the market, of the present utility model being characterised in that: described anti-resorption pad adopts the shape project organization of the skilful ramp type of inner outwardly convex, further described anti-resorption pad adopts rubber integrally formed.

The beneficial effects of the utility model are:A kind of dental handpiece heads of anti-resorption, because the anti-resorption pad of head inside adopts the shape project organization of the skilful ramp type of inner outwardly convex, and adopt rubber integrally formed, in the time that dental handpiece quits work, the inside outwardly convex part of anti-resorption pad can effectively and be pressed outer shaft sleeve and be produced tight friction, effectively prevent the phenomenon of air pressure resorption, simultaneously this kind of friction also can effectively be shortened after the rotation of pressing outer shaft sleeve and car pin due to the continuous time turning of inertia, prevent from pressing after dental handpiece from stopping after the rotation of outer shaft sleeve and car pin because the continuous transduction of inertia causes the injury to oral cavity. the dental handpiece heads of the anti-resorption of the utility model is zero resorption phenomenon almost, effectively improves the air pressure energy transformation ratio in head, improves the service life of head and mobile phone.

Brief description of the drawings

Fig. 1 is package assembly schematic diagram of the present utility model;

In figure: 1-crosshead body, 2-wind wheel, 3-o type circle (a), 4-packing ring, 5-bearing, 6-car pin, 7-presses outer shaft sleeve, the anti-resorption pad of 8-, and 9-presses rear end cap, cover base after 10-head, 11-head bearing holder (housing, cover), 12-spring, 13-presses bonnet, 14-waveform splinter, 15-bearing, 16-o type circle (b).

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Referring to accompanying drawing 1, the utility model: a kind of dental handpiece heads of anti-resorption, comprise: crosshead body, wind wheel, o type circle (a), packing ring, bearing, car pin, press outer shaft sleeve, anti-resorption pad, press rear end cap, cover base after head, head bearing holder (housing, cover), spring, press bonnet, waveform splinter, bearing, o type circle (b), the assemble method of its each parts is with consistent in the market, at this without detailed description, innovative point of the present utility model is: its anti-resorption pad adopts the shape project organization of the skilful ramp type of inner outwardly convex, further its anti-resorption pad adopts rubber integrally formed, in conventional dental mobile phone, what the anti-resorption pad of head section adopted is metallic gasket and is plane, this kind of cost is low, but due to the reason metallic gasket of precision with there is all the time gap by last item, thereby cause resorption phenomenon also cannot avoid all the time, then the structure of the anti-resorption pad in the dental handpiece heads of the anti-resorption of the utility model, in the time that dental handpiece quits work, the inside outwardly convex part of anti-resorption pad can effectively and be pressed outer shaft sleeve and be produced tight friction, effectively prevent the phenomenon of air pressure resorption, simultaneously this kind of friction also can effectively be shortened after the rotation of pressing outer shaft sleeve and car pin due to the continuous time turning of inertia, prevent from pressing after dental handpiece from stopping after the rotation of outer shaft sleeve and car pin because the continuous transduction of inertia causes the injury to oral cavity. the dental handpiece heads of the anti-resorption of the utility model is zero resorption phenomenon almost.

Claims (1)

1. a dental handpiece heads for anti-resorption, comprising: crosshead body, wind wheel, o type circle (a), packing ring, bearing, car pin, presses outer shaft sleeve, anti-resorption pad, presses rear end cap, cover base after head, head bearing holder (housing, cover), spring, presses bonnet, waveform splinter, bearing, o type circle (b), it is characterized in that: described anti-resorption pad adopts the shape project organization of the skilful ramp type of inner outwardly convex, further, described anti-resorption pad adopts rubber integrally formed.
