Description
Technical field
The utility model belongs to the technical field of dentist's hand-held set, is related to the parts of dentist's hand-held set, more particularly to one
Plant the nose assembly provided with oil sealing.
Background technology
At present, the nose assembly of existing dentist's hand-held set is no oil sealing, and movement is directly installed in after loading onto bearing
Inside head shell.This nose assembly often comes with some shortcomings a little：Scrap is easily accessible in dentist's hand-held set when a, work
Movement, causes movement to damage；B, dentist's hand-held set service life are short；C, cross-infection risk are big.
Therefore, a kind of necessary nose assembly provided with oil sealing of design, to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is to provide a kind of nose assembly provided with oil sealing, to reduce scrap into dentist's hand-held set
Inside, extends the service life of dentist's hand-held set, and reduces the risk of bacterial infection and virus.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of head group provided with oil sealing
Part, including head shell, elastic buckles and gear shaft provided with outlet, the elastic buckles are fixed on gear shaft, and the gear shaft can
It is rotatablely installed in the head shell, one end of the elastic buckles stretches on the outlet, the head shell that the exit can
Oil sealing is rotatablely equipped with, the oil sealing is provided with through hole, and one end of the elastic buckles is set in the through hole of the oil sealing, the bullet
Property button and the oil sealing through hole be interference fitted.
Further, the oil sealing, which is provided with edge, the head shell, is provided with step at the opening, the oil sealing suit
The step coordinates with the edge when opening.
Further, the oil sealing coordinates with the opened gap, the gap value between the oil sealing and the head shell
For 0.1mm.
Further, the elastic buckles are set in the gear shaft, are transition between the elastic buckles and the gear shaft
Coordinate, glue is provided between elastic buckles and the gear shaft, so that elastic buckles are integrally fixed with gear shaft, the head shell
Bearing side pad is housed, the elastic buckles pass through bearing side pad between the interior gear shaft and the oil sealing.
Further, the making material of the oil sealing is resistant to elevated temperatures plastics.
The utility model beneficial effect：Nose assembly of the present utility model, its head shell is provided with oil sealing, the oil sealing and bullet
Property button interference fit, with head shell gap coordinate, due to oil sealing and head shell gap value very little, scrap is difficult to enter into head shell
Interior movement, so as to extend the service life of dentist's hand-held set, reduces the risk of dentist's hand-held set bacterial infection and virus.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in the utility model embodiment is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of the utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, a kind of nose assembly provided with oil sealing of the present embodiment.The nose assembly includes setting
There are head shell 1, elastic buckles 2, gear shaft 3 and the oil sealing 4 of outlet.Elastic buckles 2 are set in gear shaft 3, elastic buckles 2 and gear shaft
Interference fits between 3, are provided with glue between elastic buckles 2 and gear shaft 3, interference fits+glue connection makes elastic buckles 2 and gear shaft
3 are integrally fixed.Gear shaft 3 is pivotally mounted in head shell 1, and the lower end of elastic buckles 2 is stretched into the outlet of head shell 1.Machine
Step is machined with the upper outlet of head capsule 1, oil sealing 5 is machined with edge 51, and step coordinates with edge 51 when oil sealing 5 is set in opening,
Gap coordinates between oil sealing 5 and opening, and the gap value between oil sealing 5 and head shell 1 is designed as 0.1mm, therefore oil sealing 5 is in head
It is rotatable on shell 1.Through hole is machined with oil sealing 5, one end of elastic buckles 2 is set in the through hole of oil sealing 5, elastic buckles 2 and oil sealing 5
Through hole interference fit.
Preferred design, is equipped with bearing side pad 4 between the inner gear shaft 3 of head shell 1 and oil sealing 5, elastic buckles 2 pass through bearing
Side pad 4；The making material of oil sealing 5 is resistant to elevated temperatures plastics, can produce oil sealing 5 by molding injection moulding, its sealing
It is very good.
The operation principle of nose assembly of the present utility model：When gear shaft 3 rotates, connected by interference fit with elastic buckles 2
The oil sealing 5 connect can be as gear shaft 3 rotates together, and due to oil sealing 5 and the gap value very little of head shell 1, scrap is difficult to enter into machine
Movement in head capsule 1, extends the service life of dentist's hand-held set, reduces the wind of dentist's hand-held set bacterial infection and virus
Danger.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modifications, equivalent substitutions and improvements made etc. should be included in the utility model
Protection domain within.
