Abstract
The utility model discloses a kind of dental abrading bent angles, including shell, transmission shaft, rotating member and polishing rotor, transmission shaft is installed inside the housing, one end is contacted with driving member to be connected, driving member is mutually perpendicular to transmission shaft, and polishing rotor fixation is installed on driving member, compared with prior art, the beneficial effects of the utility model are: in driving member and transmission shaft contact position, equipped with rotation angle, expand polishing area, convenient for cleaning dead angle, and corner is equipped with bent angle on shell, and cleaning is polished in oral cavity convenient for protruding into.
Description
Technical field
The utility model relates to a kind of dental abrading bent angles, belong to medical instrument product technical field.
Background technique
Dental abrading bent angle is one of the basic medical instrument applied in the department of stomatology, by driving polishing rotor on bent angle low
To carry out cleaning polishing to oral cavity, polishing bent angle cooperation water toothpick uses simultaneously, need to directly go deep into oral cavity for speed rotation
Portion, so requiring that extension obtains to the corner in oral cavity, polishing bent angle in the prior art mostly uses linear type to design greatly, this
Design is inconvenient to protrude into oral cavity depths, has some products to have using square turning, but polishing rotor extension elongation is shorter, no
Conducive to the cleaning of depth location, and polishing rotor can only be rotated, and cleaning dynamics is limited.
Utility model content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to provide a kind of dental abrading is curved
Angle while polishing rotor rotation, can there is the swing of an angle using angle design is turned to by reasonably optimizing structure,
Improve cleaning efficiency.
To realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
A kind of dental abrading bent angle, including shell, transmission shaft, rotating member and polishing rotor, transmission shaft are mounted on shell
Inside, one end is contacted with driving member to be connected, and driving member is mutually perpendicular to transmission shaft, and shell is equipped with transmission shaft mounting groove and biography
Moving part mounting groove, angle is 80 °~140 ° between transmission shaft mounting groove and driving member mounting groove, and transmission shaft is mounted on transmission shaft peace
In tankage, driving member is mounted in driving member mounting groove, and transmission shaft one end is equipped with semilune boss, correspondingly, in driving member
It is equipped with groove with transmission shaft first half of the month shape boss contact position, the triangular structure part of a protuberance is additionally provided in groove, is being passed
Moving axis is equipped with a card slot, and shell is equipped with location hole, and buckle is formed across location hole and extending into the card slot of transmission shaft
Fixed limit.
Preferably, it is additionally provided with the triangular structure part of a protuberance in groove, triangular structure part angle is 30 °~
120 °, the rotation of semilune boss drives driving member to swing, and the angle of triangular structure part is directly related with swing angle.
It is highly preferred that cancelling the location hole on buckle and shell, wall is set in a fastener and rotation axis inside the shell
Groove position is corresponding, due to there is lubricating oil auxiliary between driving member and transmission shaft, oil leak is easy at location hole and buckle, so adopting
Replaced with enclosed construction, optimizes product.
Compared with prior art, the utility model has the beneficial effects that being equipped with and turning in driving member and transmission shaft contact position
Dynamic angle is capable of forming the swing of certain angle on the basis of rotation, expands polishing area, convenient for cleaning dead angle, and shell
Upper corner is equipped with bent angle, and cleaning is polished in oral cavity convenient for protruding into.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the preferred embodiment of dental abrading bent angle provided by the utility model；
Fig. 2 is a kind of diagrammatic cross-section of the preferred embodiment of dental abrading bent angle provided by the utility model；
Fig. 3 is a kind of structural schematic diagram of the preferred embodiment of dental abrading bent angle provided by the utility model.
Specific embodiment
With preferred embodiment is made to the utility model further detailed complete illustrate with reference to the accompanying drawing.
Fig. 1-3 is a kind of preferred embodiment schematic diagram of dental abrading bent angle provided by the utility model.As Fig. 1-3 institute
Show, which includes shell 1, transmission shaft 2, rotating member 3 and polishing rotor 4, and transmission shaft 2 is mounted in shell 1
Portion, one end is contacted with driving member 3 to be connected, and driving member 3 is mutually perpendicular to transmission shaft 2, and shell 1 is equipped with transmission shaft mounting groove 101
And driving member mounting groove 102, angle is 80 °~140 ° between transmission shaft mounting groove 101 and driving member mounting groove 102, transmission
Axis 2 is mounted on 101 in transmission shaft mounting groove, and driving member 3 is mounted in driving member mounting groove 102, and 2 one end of transmission shaft is equipped with half a month
Shape boss 201 is correspondingly equipped with groove 301, groove in driving member 3 and 2 first half of the month of transmission shaft shape boss, 201 contact position
The triangular structure part 302 of a protuberance is additionally provided in 301,302 angle of triangular structure part is 30 °~120 °, in transmission shaft 2
It is equipped with a card slot 202, shell 1 is equipped with location hole 103, and buckle 5 passes through location hole 103 and extend into the card of transmission shaft 2
Fixed limit is formed in slot 202.
In use, transmission shaft 2 rotates, and the semilune boss 201 on transmission shaft 2 also can rotate, semilune boss
201 intermittent on the triangular structure part 302 on 3 groove 301 of driving member can touch, since contact surface is triangular ramp,
So driving member 3 can also be swung while rotation with circulation.
It is worth noting that, another structure is the location hole cancelled on buckle and shell, wall sets one inside the shell
Fastener is corresponding with groove position in rotation axis due to there is lubricating oil auxiliary between driving member and transmission shaft, at location hole and buckle
It is easy oil leak, so replacing using enclosed construction, optimizes product.
Compared with prior art, the utility model has the beneficial effects that being equipped with and turning in driving member and transmission shaft contact position
Dynamic angle is capable of forming the swing of certain angle on the basis of rotation, expands polishing area, convenient for cleaning dead angle, and shell
Upper corner is equipped with bent angle, and cleaning is polished in oral cavity convenient for protruding into.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
