Description

Reinforcing structure of oral mirror

The present invention relates to a reinforcing structure of an oral mirror, especially a reinforcing rib provided at the connecting portion of the oral mirror.

In fact, when dentists diagnose and treat patients, in addition to visual inspection, they often need to use the reflected image of the oral mirror to observe the condition of the teeth or gums in the patient's mouth. Correct medical treatment; therefore, a dental mirror is a necessary medical device for dentists to assist in the diagnosis. In addition, in order to make the oral mirror have the functions of the hook of the dentist's equipment and the tongue depressor, and at the same time can illuminate the tooth image, the oral mirror is usually equipped with a double-sided mirror, as shown in Fig. The oral mirror 10 is made of plastic material, and includes a handle 11 and a double-sided mirror portion 12 . A connecting portion 13 is provided between one end of the handle 11 and the double-sided mirror portion 12 , and the connecting portion 13 is adjacent to the double-sided mirror portion 12 . The end of the handle bar 11 is provided with a curved arc section 14, so that the double-sided mirror portion 12 can extend downward to have a drop with the handle bar 11, so that the double-sided mirror portion 12 can easily penetrate deeper into the patient's oral cavity, and The connecting portion 13 is provided with an upward curved arc section 15 adjacent to the double-sided mirror portion 12, so that the double-sided mirror portion 12 and the handle 1 have a bending angle, which can be used as a function of pulling the corner of the mouth or pressing the tongue, and makes the double-sided mirror portion 12 and the handle 1 have a bending angle. The double-sided mirror portion 12 has the best viewing angle; however, when the dentist uses the oral mirror 10 to extend into the patient's oral cavity for medical treatment, open the corner of the mouth or press the tongue for protection, the connecting portion 13 is also a part of the patient's oral cavity. For the comfort of the patient and not obstructing the medical vision, the connecting portion 13 should not be thick and thick in design, and usually a thinner and thinner Design is based, therefore, the connecting portion 13 is the weakest part of the oral mirror 10 , especially the lower curved segment 14 and the upper curved segment 15 are stronger due to the force angle and stress concentration of the oral mirror 10 . It is weaker, and it is easy to be deformed when pulling the corner of the mouth or pressing the tongue, which makes it difficult to operate. The service life of 10 is greatly reduced; therefore, how to increase the strength of the connecting portion 13 and prolong the service life of the oral mirror 10 needs to be improved.

The main purpose of this creation is to solve the above-mentioned problems, and to provide a reinforcing structure for an oral mirror. The main technology and purpose of this creation is to provide reinforcing ribs on the lower curved segment and the upper curved segment of the connecting portion, thereby strengthening the The weak point of the connecting part can achieve the practical effect of increasing the strength and prolonging the service life.

According to the above purpose of the present invention, a reinforcing structure of an oral mirror is provided, which comprises: a handle and a double-sided mirror portion, a connecting portion is provided between one end of the handle and the double-sided mirror portion, and the connecting portion is adjacent to the double-sided mirror portion. The grip rod end is provided with a lower curved arc segment, and the connecting portion adjacent to the double-sided mirror portion is provided with an upper curved segment, the lower curved segment is provided with a lower reinforcing rib, and the upper curved segment is provided with an upper reinforcing rib.

In an embodiment of the present invention, the lower reinforcing rib and the upper reinforcing rib are arc convex ribs.

In an embodiment of the present invention, one end of the lower reinforcing rib extending in the direction of the double-sided mirror portion and one end of the upper reinforcing rib extending in the direction of the handle form a relative overlapping stagger on the lower and upper surfaces of the connecting portion section.

In an embodiment of the present invention, the length of the staggered section is equal to or greater than 1 mm.

With the above structure, the lower reinforcement rib and the upper reinforcement rib increase the flexural strength of the connecting portion, thereby achieving the practical effects of not being easily deformed and prolonging the service life.

In order to make your review committee have a further understanding of this creation, hereby give a preferred embodiment and cooperate with the drawings, and the details are as follows:

Please refer to FIGS. 2 to 4. An oral mirror 20 includes a handle 21 and a double-sided mirror portion 22. A connecting portion 23 is provided between one end of the handle 21 and the double-sided mirror portion 22. The connecting portion 23 There is a lower curved arc section 24 adjacent to the end of the handle 21, and an upper curved arc section 25 is formed at the end of the connecting portion 23 adjacent to the double-sided mirror portion 22. The main feature is that the lower curved arc section 24 is provided with a reinforcement. The rib 26, the upper curved segment 25 is provided with an upper reinforcing rib 27; by the above-mentioned structure, the lower reinforcing rib 26 and the upper reinforcing rib 27 increase the flexural strength of the connecting portion 23, thereby achieving that the oral mirror 20 is not easily deformed And the practical effect of prolonging the service life.

The composition, function and effect of the above-mentioned embodiment are described in detail as follows: As shown in Figures 2 to 4, the reinforcing rib 26 and the upper reinforcing rib 27 are arc convex ribs under the present creation, but not limited to this, it increases In order to increase the strength and rigidity of the connecting portion 23 , the lower reinforcing rib 26 extends from the bottom central surface of the lower curved segment 24 to both ends of the connecting portion 23 for support, and the upper reinforcing rib 27 is supported by the top of the upper curved segment 25 central The surface extends to both ends of the connecting portion 23 for support; furthermore, one end of the lower reinforcing rib 26 extending toward the direction of the double-sided mirror portion 22 and one end of the upper reinforcing rib 27 extending toward the direction of the handle 21 are on the connecting portion 23 The lower and upper surfaces form a staggered section L with overlapping relative positions, and the length of the staggered section L is equal to or greater than 1 mm. As a result, there is at least one reinforcement support at any cross-sectional position of the connecting portion 23, which is understandable. , the connecting portion 23 is comprehensively reinforced, of course, the strength of the oral mirror 20 can be increased, so that the connecting portion 23 is not easily deformed, thereby prolonging the service life.

When the present invention is used as the hook function to open the corners of the mouth, the lower curved arc section 24 bears the pressing force, the lower reinforcing rib 26 supports the top support, and the upper curved arc section 25 bears the expanding force, the The upper reinforcing rib 27 provides tension support; when the present invention is used as a tongue depressor function to protect the tongue, the lower curved segment 24 bears the force of expansion, the lower reinforcement rib 26 provides tension support, and the upper curved segment The segment 25 bears the pressing force, and the upper reinforcing rib 27 supports the top support; therefore, the lower reinforcing rib 26 and the upper reinforcing rib 27 can ensure that the oral mirror 20 is not easily deformed, and the operation is not affected by the deformation.

With the above structure, the lower reinforcing rib 26 and the upper reinforcing rib 27 increase the bending strength of the connecting portion 23 , thereby achieving the practical effect that the oral mirror 20 is not easily deformed and can prolong the service life.

The above-mentioned embodiments are only preferred embodiments to fully illustrate the present creation, and are not intended to limit the characteristics of the present creation. Any re-creation using the technical means and creation principles related to the present creation is still the present creation. Equivalent structural creative category.
