Description
Technical field
This utility model relates to oral cavity medical apparatus, is specifically related to a kind of pressing type dental handpiece.
Background technology
Dental handpiece is 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 dental handpiece is used, 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.Purl formula high speed dental turbo mobile phone need to carry out loading-unloading vehicle pin with purl device; Pressing type high speed dental turbo mobile phone does not need purl device, only needs to press head bonnet, just can realize the handling of car pin, and the bonnet of pressing type dental handpiece is arranged with resilient mounting, after bonnet is pressed, realizes bonnet is carried out to resilience.Existing pressing type dental handpiece adopts spring as resilient mounting, and it takes up space larger, also there will be the situation of unbalance stress while pressing.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of have stressed evenly, compact conformation, pressing type dental handpiece little and that elastic effect is good takes up space.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Pressing type dental handpiece, comprise handle and the head that is connected to handle front end, described head comprises bonnet, described bonnet comprises the supporter of hollow columnar and the button of semi-enclosed hollow columnar of both ends open, the outer wall of described supporter upper end raises up and forms the bypass road of ring-type, and the open end of button is inserted in bypass road and can be moved up and down along bypass road; Between button and supporter, be provided with a shell fragment that bends to saddle type or waveform, the bottom of this shell fragment is arranged on the inwall of supporter, and two, top peak withstands on respectively on the capping inwall of button.
In order to make supporter and button stressed even, described shell fragment is saddle type, and its planar structure is loop configuration.More preferably, the planar structure of described shell fragment is circular loop configuration.
In order to make the resilience force of shell fragment larger, and make on the inwall of the supporter that the resilience force of shell fragment internal ring distributes more uniformly, the minimum point of described shell fragment internal ring withstands on the inwall of supporter, and two peaks of shell fragment outer shroud withstand on the capping inwall of button.
Such scheme is preferred, and in described shell fragment, ring diameter is φ 4-6mm, and outer ring diameter is φ 7-9mm.
Such scheme is preferred, and described shell fragment is when sprung push buttons, and the rise of shell fragment is 1-2mm.
In order to make the more compact structure of bonnet, circuit in the inwall of described supporter upper end raises up and forms, and this interior circuit extends internally at peak, and the bottom of described shell fragment is arranged on the interior circuit of supporter.
Such scheme is preferred, and the lower end inwall of described supporter is outwards recessed to form inner groove, is provided with O-ring gasket in inner groove.
Such scheme is preferred, and described shell fragment is made by beryllium-bronze or rustless steel.
Compared with prior art, this utility model use saddle type shell fragment or waveform splinter are as the resilient mounting of bonnet, the internal ring of shell fragment is stuck on the interior circuit of supporter, the outer shroud two ends of shell fragment are clamped on respectively on the capping inwall of button, the elastic force of shell fragment can act on bonnet uniformly like this, and elastic effect is good; And shell fragment is with respect to existing spring, and can be compacter be arranged between support member and button, makes whole rear cover structure compact, and volume is little, occupies little space.
