Abstract
The invention discloses a mandrel of a pressing type dental high-speed turbine handpiece. The mandrel comprises a hollow cylindrical shaft sleeve of which the two ends are opened, and a needle clamping piece nested in the shaft sleeve, wherein the front part of the shaft sleeve is nested with the hollow cylindrical mandrel meson of which the two ends are opened; the needle clamping piece is a four-pedal spring which is nested on the back part of the shaft sleeve; the four-pedal spring is connected with a rebounding device which controls forward and backward movement of the four-pedal spring to realize mounting and dismounting of a machine needle. According to the mandrel of the pressing type dental high-speed turbine handpiece provided by the invention, the four-pedal spring is nested inside the shaft sleeve, an axle hole for inserting the four-pedal spring of the machine needle is pressed tightly by utilizing the pressing force of a spring against the four-pedal spring, so that the machine needle is firmly clamped; besides, by using the rebounding device consists of a pressing member and the spring, the four-pedal spring can be pressed to an optimal position, the clamping force is large, and the machine needle can be mounted and dismounted quickly; moreover, the mandrel is not easily damaged and is long in service life.
Description
Technical field
The present invention relates to oral cavity medical apparatus, be specifically related to a kind of mandrel of pressing type high speed dental turbo mobile phone.
Background technology
High speed dental turbo mobile phone came out in nineteen fifty-seven, was a kind of high speed rotating with air stream drives cutting medical apparatus and instruments, rotating speed can by 200,000 revs/min～600,000 revs/min not etc., it is mainly used for cutting tooth body, prepares tooth cavity, prepares thread form and finishing thread form etc.
When high speed dental turbo mobile phone uses, need to install adaptive car pin, utilize the high speed rotating of movement, band motor-car pin high speed rotating, realizes the operations such as polishing, cutting.According to the mounting means of car pin, existing high speed dental turbo mobile phone is mainly divided into pressing type and purl formula.Pressing type high speed dental turbo mobile phone does not need purl device, only need to press head bonnet, just can realize the handling of car pin, what pressing type high speed dental turbo mobile phone clamping trolley pin was used is the mandrel of pressing in movement, because car pin needs high speed rotating when working, so the clamping action of mandrel is extremely important, as unreasonable in core shaft structure, will cause chucking power low, may occur in the course of the work the abnormal phenomenas such as car pin comes off, mobile phone vibration, when serious, can injure patient's personal safety.As the Chinese utility model patent " a kind of pressing type high speed turbine mobile phone " that notification number is CN202619874U, its car pin is to be connected in mandrel endoporus by clamping device; Also have the Chinese utility model patent " mandrel of dental mobile phone " that notification number is CN201822926U, utilize friction-type chuck to form projection at mandrel inwall, play the effect of clampingc car pin.These core shaft structures are unreasonable, cause the problems such as axle core is inadequate to the chucking power of car pin, chuck is easy to wear, service life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide the mandrel of the pressing type high speed dental turbo mobile phone of a kind of high chucking power, not fragile, long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Described in the mandrel of pressing type high speed dental turbo mobile phone, the front portion of axle sleeve is nested with the mandrel meson of the hollow columnar of both ends open, described folder pin part is pintongs spring, this pintongs spring is nested in the rear portion of axle sleeve, thus described pintongs spring and control it and move forward and backward the resilient mounting of realizing the dismounting of car pin and be connected.When installation car pin, pintongs spring is promoted toward front end, then car pin is inserted in pintongs spring, promote car pin and move toward rear end, spring opens and compresses pintongs spring, and then makes pintongs spring clampingc car pin; When dismounting car pin, promote pintongs spring and move toward front end, pintongs spring unclamps car pin, then car pin is taken out.
Preferably, described resilient mounting can comprise spring and pressing piece, and one end of described spring is stuck on the rear end of mandrel meson, and the other end is stuck on the front end of pintongs spring, and described pressing piece is connected with the rear end of pintongs spring.
The front end of described pintongs spring is provided with pad, to strengthen the contact area of pintongs spring and spring, anti-skidding.
Preferably, described resilient mounting comprises spring and pressing piece, and described pressing piece is the font of falling T, the shank that comprises press section and its front end, the front end of shank is connected with the rear end of pintongs spring, and described spring housing is outside shank, one end of spring is stuck on axle sleeve, and the other end is stuck on press section.
In order further to strengthen the motive force to pintongs spring, described spring is Rectangular Spring.
In order further to strengthen the chucking power of pintongs spring, described pintongs spring is the taper pintongs spring arranging towards rear end.
Preferably, in described axle sleeve, be pyramidal structure with pintongs spring corresponding position.
Compared with prior art, the present invention is nested in pintongs spring in axle sleeve, and utilizes the thrust of spring to pintongs spring, and the axis hole that is used in the pintongs spring that plugs car pin is compacted, so can be firm clamp car pin; And utilize the resilient mounting that formed by pressing piece and spring, and not only pintongs spring can be pressed onto to optimum position, its chucking power is large, and quick to the handling of car pin, not fragile mandrel also in addition, long service life.
