Abstract
The utility model provides a connecting shaft wind wheel of a dental handpiece, which comprises a wind wheel (1) and a connecting shaft (2) inserted in the wind wheel (1), wherein the center of the wind wheel (1) is provided with a connecting shaft hole (12) of which the diameter is matched with the connecting shaft (2); the inner wall of the connecting shaft hole (12) is provided with clamping shafts (11); small holes (21) are arranged on the connecting shaft (2); and the clamping shafts (11) are matched with the small holes (21). The connecting shaft wind wheel of the dental handpiece has low noise and low manufacturing cost.
Description
Technical field
This utility model relates to the medicine instrument field, relates in particular to a kind of dental handpiece connecting shaft wind wheel.
Background technology
Two kinds of dental handpiece connecting shaft wind wheels that exist in the prior art have two kinds at present, and a kind of is connecting shaft and wind wheel one, use plastics disposable injection molded, but this connecting shaft wind wheel noise when running up are very big; Another kind of connecting shaft wind wheel, connecting shaft use steel or copper to become, and wind wheel makes and is made of a steel, this connecting shaft wind wheel must use specific bindiny mechanism to fix when assembling, assemble more responsiblely, and the cost that uses copper or steel is unfavorable for applying on a large scale than higher.
Summary of the invention
The purpose of this utility model provides a kind of dental handpiece connecting shaft wind wheel, low, the low cost of manufacture of noise.
The technical solution of the utility model is: a kind of dental handpiece connecting shaft wind wheel, comprise: wind wheel 1 and the connecting shaft 2 that inserts in wherein, described wind wheel 1 center is shaped on the connecting shaft hole 12 that diameter cooperates with connecting shaft 2, described connecting shaft hole 12 inwalls have axis 11, be shaped on aperture 21 on the described connecting shaft 2, described axis 11 cooperates with described aperture 21.
Optionally, described axis 11 is square, and described aperture 21 is square.
Optionally, the number of described axis 11 is consistent with the number of described aperture 21, is more than 2.
Optionally, the number of described axis 11 and described aperture 21 is 2～6.
Optionally, being made of plastics of described wind wheel 1, described connecting shaft 2 is made by copper, steel or aluminum.
This utility model connecting shaft hole inwall has axis, is shaped on aperture on the connecting shaft, and axis cooperates with aperture, makes wind wheel and connecting shaft closely cooperate, and can run up.
Further, this utility model axis and aperture all are square, and it is tightr that square axis and square aperture cooperate.
Further, the number of this utility model axis and aperture is consistent, is more than 2, and it is tightr to make that wind wheel and connecting shaft cooperate.
Further, the number of this utility model axis and aperture is 2～6, and axis and aperture cooperate easily.
Further, this utility model wind wheel is made of plastics, connecting shaft is made by copper, steel or aluminum, saves cost with respect to the connecting shaft wind wheel that prior art all adopts steel or copper to become, and noise was low when the connecting shaft wind wheel that all has plastics to make with respect to wind wheel in the prior art and connecting shaft ran up.

Fig. 1 is the wind wheel structure sketch map that this utility model provides;
Fig. 2 is the connecting shaft cutaway view that this utility model provides;
Fig. 3 is wind wheel and the connecting shaft assembling sketch map that this utility model provides.
The specific embodiment
Below describe the dental handpiece connecting shaft wind wheel that this utility model provides in detail by accompanying drawing.
The dental handpiece connecting shaft wind wheel that this utility model provides comprises: wind wheel 1 and the connecting shaft 2 that inserts in wherein.As shown in Figure 1, wind wheel 1 center is shaped on the connecting shaft hole 12 that diameter cooperates with connecting shaft 2, and connecting shaft hole 12 inwalls have axis 11, and axis 11 is square, has 2～4.As shown in Figure 2, be shaped on aperture 21 on the connecting shaft 2, aperture is square, and the number of aperture is consistent with the number of axis, is more than 2, and preferred number is 2～6.Connecting shaft 2 is inserted in the connecting shaft hole of wind wheel 1 as shown in Figure 3, and axis 11 snaps in the aperture on the connecting shaft 2, guarantees that connecting shaft wind wheel that unlike material is made can adapt to run up, and can closely cooperate.
This utility model wind wheel 1 is made of plastics, and connecting shaft 2 is made by copper, steel or aluminum.Save cost, and noise is low when running up.
The above only is preferred embodiment of the present utility model; not in order to restriction this utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
