Description

Mouth mirror

Technical Field

The utility model relates to an oral medical appliances technical field, concretely relates to mouth mirror.

Background

The oral cavity is the initial part of the digestive tract, and the oral cavity has organs such as teeth, tongue and the like. The front wall of the oral cavity is lip, the side wall is cheek, the top is palate, the bottom of the oral cavity is mucous membrane and muscle. The oral cavity is divided into an oral cavity vestibule at the front outer side and an inherent oral cavity at the back inner side by the upper dental arch and the lower dental arch.

During the inspection of oral cavity disease, often can use mouth mirror, frontal mirror, mouth mirror is the medical appliances who comprises mirror surface and handle, frontal mirror then assembles the light of near light source and shines into the concave mirror in oral cavity, but because the mirror surface of mouth mirror is fixed connection with the handle, so at the in-process that uses mouth mirror, the doctor is inevitable can be unable direct observation to the oral cavity condition of reflection in the mouth mirror, need the position that doctor oneself changed the head to look over the oral cavity condition in the mouth mirror this moment, and the position of changing the head probably influences the position that the frontal mirror shines after focusing, and then influences the inspection of doctor to the oral cavity.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the technical problem that above-mentioned exists, a can change the luminous mouth mirror of mouth mirror surface and handle angle is provided for change the head position can influence the doctor to the inspection in oral cavity when solving the inspection oral cavity.

In order to solve the technical problem, the utility model provides a following technical scheme: a mouth mirror comprises a mirror surface, a rotating column and a handle, wherein the handle is hollow, two ends of the handle are arranged in an open mode, a rotating shaft is arranged in the handle, one end of the rotating shaft is fixedly connected with a helical gear, the other end of the rotating shaft is fixedly connected with a rotating handle, the rotating handle is positioned outside the handle and is rotationally connected with the handle, a fixed shaft is arranged at one end, away from the rotating handle, of the handle, the fixed shaft is rotationally connected with a central shaft of the rotating column, a groove is formed in the rotating column, and a rack meshed with the helical gear is arranged on the wall of the groove; the mirror surface is provided with a luminous source, the back of the mirror surface is provided with a battery used for supplying power to the luminous source, and the mirror surface is fixedly connected to the rotating column.

The utility model discloses the theory of operation: the rotation handle drives the rotation axis to rotate when rotating, the rotation axis rotates and drives the helical gear to rotate, the helical gear drives the rotation column to rotate through the rack meshed with the helical gear, the rotation column drives the mirror surface to rotate around the fixed shaft when rotating, the mirror surface can be driven to rotate when rotating the rotation handle through the linkage effect, during use, the luminous source is opened, the mirror surface is placed in the oral cavity, the luminous source illuminates the oral cavity, and meanwhile, a doctor observes the conditions in the oral cavity through the mirror surface, when the angle of the oral cavity mirror needs to be adjusted, the rotation handle is rotated, the angle of the mirror surface is adjusted, and the mirror surface is adjusted.

The beneficial effects of the utility model are that this scheme throws light on to the oral cavity through luminous mirror, rotates the handle through rotating simultaneously, drives the mirror surface through the interlock and rotates around the dead axle, has realized the angular adjustment of mouth mirror surface, does not lean on the condition that removes the head and survey in the oral cavity with the doctor, and luminous mirror surface directly throws light on to the oral cavity simultaneously, has avoided the position that changes the head to influence the position that shines after the frontal mirror is focused on.

The following is an optimization of the basic scheme:

furthermore, the rotating handle is provided with anti-skid grains. The purpose is to prevent the situation of slipping when rotating the turning handle.

Further, the luminous source adopts an LED lamp. Because the LED is small in size and convenient to place on the mirror surface, the LED lamp is used as a luminous source.

Furthermore, a transparent waterproof cover is arranged on the LED. Because the in-process in the detection oral cavity, the mirror surface can be stained with saliva unavoidably, because saliva can cause the damage to the LED lamp for liquid, so install transparent buckler additional on LED, do not influence the luminous of LED lamp again when waterproof.

fig. 2 is a schematic structural diagram of the mirror in fig. 1.

Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the LED mirror comprises a mirror surface 1, a rack 2, a rotating column 3, a fixed shaft 4, a helical gear 5, a rotating shaft 6, a handle 7, anti-skidding threads 8, a rotating handle 9, an LED lamp 10 and a waterproof cover 11.

The embodiment is basically as shown in the attached figures 1 and 2:

a mouth mirror comprises a mirror surface 1, a rotating column 3 and a handle 7, wherein the handle 7 is hollow, openings are formed in two ends of the handle 7, a rotating shaft 6 is arranged in the handle 7, a helical gear 5 is welded at one end of the rotating shaft 6, a rotating handle 9 is connected to the other end of the rotating shaft 6 in a threaded mode, the rotating handle 9 is located outside the handle 7 and is rotatably connected with the handle, and anti-skid grains 8 are arranged on the rotating handle 9; the welding of the one end of handle 7 has dead axle 4, and dead axle 4 rotates with the center pin department that rotates post 3 to be connected, rotates and is equipped with the recess on the post 3, is equipped with the rack 2 of 5 meshing helical gears on the cell wall of recess, and the annular bonding has a plurality of LED lamps 10 on the mirror surface 1, and the adhesion has transparent buckler 11 on the LED lamp 10, and the back of mirror surface 1 is equipped with the battery that is used for the power supply of LED lamp 10, and mirror surface 1 welds on rotating post 3.

During the use, open LED lamp 10, put into the oral cavity with mirror surface 1, LED lamp 10 throws light on the oral cavity, when saliva is carelessly dripped on LED lamp 10, transparent water proof cover 11 blocks saliva outside LED lamp 10, make LED lamp 10 can not damaged, the condition in the oral cavity is observed through mirror surface 1 to the doctor simultaneously, when the 1 angle of mirror surface of needs adjustment mouth mirror, rotate handle 9, it drives mirror surface 1 through the interlock effect and rotates around dead axle 4, realize the angular adjustment of mirror surface 1.

For those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
