Embodiment Construction

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] like figure 1 , figure 2 , image 3 , Figure 4 As shown, an anti-rotation structure used in the handle of an ultrasonic dental scaler includes a transducer 1 , a rear snap ring 2 , and a handle housing 3 . The rear snap ring 2 is sleeved on the main rod 110 of the transducer 1, and the rear snap ring 2 is engaged with the main rod 110. The snap fit between the rear snap ring 2 and the main rod 110 is used to prevent the rear Relative rotation occurs between the clasp 2 and the main rod 110 . The handle shell 3 is sleeved on the rear snap ring 2, and the rear snap ring 2 is engaged with the handle shell 3, and the snap fit between the rear snap ring 2 and the handle shell 3 is used to prevent the rear sn...

Abstract

The invention relates to an anti-rotating structure in a handle in an ultrasonic scaler. The anti-rotating structure comprises a transducer, a rear snap ring and a handle shell; the rear snap ring sleeves a main rod of the transducer, the rear snap ring is buckled with the main rod, and the buckling matching of the rear snap ring and the main rod is used for preventing the relative rotation between the rear snap ring and the main rod; and the handle shell sleeves the rear snap ring, and the rear snap ring is buckled with the handle shell, so that the buckling matching between the rear snap ring and the handle shell is used for preventing the relative rotation between the rear snap ring and the handle shell. The anti-rotating structure has the beneficial effects that by adopting the anti-rotating structure and encapsulating the structure, the comfort of the handle can be effectively improved, the power is high, and the torque transmission is reliable.

Description

technical field [0001] The invention relates to the field of dental instruments, in particular to an anti-rotation structure used in a handle of an ultrasonic dental scaler. Background technique [0002] The handle of the ultrasonic dental scaler needs to be provided with a matching position on the ultrasonic transducer and the housing respectively to prevent the relative rotation of the transducer and the housing, which is called an anti-rotation body. One way of the existing anti-rotation body is to set it on the horn of the transducer, a bayonet is set on the horn, and a corresponding protrusion is set on the shell; another way is to use piezoelectric ceramics The waterproof silicone layer is wrapped on the outside, and the waterproof silicone layer (or hard plastic layer) is provided with a card position corresponding to the outer shell. These two methods usually cause the power of the transducer to be reduced because the anti-rotation part is too large for the working ...
