[0002] Dentistry is one of the classifications of medical disciplines. In large hospitals, it is generally incorporated into the stomatology department. Dentistry mainly treats diseases related to teeth and periodontium.

[0003] During oral dental examinations, lighting equipment is often used. In the actual use process of the existing lighting equipment, although the basic lighting function can be achieved, most of the connecting rods of the existing lighting equipment are supported and fixed by the friction force between the damping rotating shafts. If a doctor accidentally touches the lighting equipment during the examination, it is easy to cause the connecting rod to shake, thereby changing the lighting angle. At this time, the doctor needs to adjust the lighting angle again and then perform an oral examination. Such a method not only increases the workload of the doctor, but also the stability of the connecting rod is poor. Therefore, it needs to be improved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, the present utility model provides a lighting device for oral dental examination, including:

[0027] A rectangular plate 1 has a cylindrical block 2 fixedly connected to the middle of the top end of the rectangular plate 1. A round rod 3 is movably sleeved inside the cylindrical block 2. An activity shaft 4 is movably sleeved inside the top end of the round rod 3. A connecting rod 5 located behind the round rod 3 is fixedly sleeved on the outer surface of the activity shaft 4. The front surface of the connecting rod 5 is movably connected to the back surface of the round rod 3;

[0028] A fixing mechanism is arranged on the front surface of the round rod 3;

[0029] Among them, the fixing mechanism includes a driving motor 6. The back surface of the driving motor 6 is fixedly connected to the front surface of the round rod 3. The other end of the output shaft of the driving motor 6 is fixedly sleeved with a rotating shaft 7. A rotating block 8 is fixedly sleeved on the outer surface of the rotating shaft 7. The other end of the rotating block 8 is fixedly sleeved with a round shaft 9. The outer surface of the round shaft 9 is movably connected to a T-shaped block 10. The top of the T-shaped block 10 is fixedly connected to a toothed plate 11. The right side of the toothed plate 11 is movably connected to the left side of the round rod 3. The outer surface of the top of the toothed plate 11 is meshed with a gear 12. The inside of the gear 12 is fixedly sleeved on the outer surface of the activity shaft 4. The right side of the gear 12 is movably connected to the left side of the round rod 3. When the toothed plate 11 moves downward, the fixing effect on the gear 12 is released.

[0030] When the driving motor 6 operates, the rotating shaft 7 will drive the rotating block 8 to rotate, and then the round shaft 9 will rotate to drive the T-shaped block 10 and the toothed plate 11 to move downward. When the toothed plate 11 is separated from the outer surface of the gear 12, the fixing effect on the gear 12 will be released. At this time, pulling the connecting rod 5 to rotate can complete the adjustment of the angle of the connecting rod 5.

[0031] Among them, a connecting block 13 is fixedly connected to the front surface of the round rod 3 and is located directly below the gear 12. The inner surface of the connecting block 13 is movably connected to the outer surface of the toothed plate 11.

[0032] The design of the connecting block 13 plays a role in limiting the toothed plate 11.

[0033] Among them, a round block 14 is fixedly sleeved on the outer surface of the activity shaft 4 and is located on the right side of the connecting rod 5. The left side of the round block 14 is movably connected to the right side of the connecting rod 5.

[0034] The design of the round block 14 plays a role in blocking the connecting rod 5.

[0035] Among them, a vertical block 15 is fixedly connected to the right side of the bottom of the connecting rod 5. A lighting lamp 16 is hinged to the bottom of the vertical block 15.

[0036] The design of the lighting lamp 16 plays a role in illuminating the oral cavity.

[0037] Among them, fixing blocks 17 are fixedly connected to the periphery of the outer surface of the lighting lamp 16. A rotating shaft 18 is movably sleeved inside the fixing block 17. A baffle 19 is fixedly sleeved on the outer surface of the rotating shaft 18. The number of baffles 19 is four, and the outer sides of the four baffles 19 are all movably connected to the inner sides of the fixing blocks 17.

[0038] The four baffles 19 rotate by ninety degrees to block the light emitted by the lighting lamp 16 and prevent the light from directly shining into the patient's eyes.

[0039] Among them, an L-shaped plate 20 is fixedly connected to the top of the lighting lamp 16. A spring 21 is fixedly connected to the top of the inner cavity of the L-shaped plate 20. The other end of the spring 21 is fixedly connected to a handle 22. The inner surface of the handle 22 is movably connected to the outer surface of the L-shaped plate 20. A latch 23 is fixedly connected to the bottom of the handle 22. The bottom of the latch 23 sequentially penetrates through the fixing block 17 and the rotating shaft 18 and extends into the inside of the rotating shaft 18. When the latch 23 moves upward, the fixing effect on the baffle 19 is released.

[0040] Pull the handle 22 upward, which will compress the spring 21 and drive the latch 23 to move upward. When the latch 23 moves to the outside of the rotating shaft 18, the fixing effect on the baffle 19 will be released. At this time, the baffle 19 rotates by ninety degrees, and the purpose of blocking the light emitted by the lighting lamp 16 can be achieved.

[0041] Among them, four round wheels 24 are movably installed around the bottom of the rectangular plate 1. The number of round wheels 24 is four, and the four round wheels 24 have the same size.

[0042] The design of the four round wheels 24 enables the overall movement of the rectangular plate 1.

[0043] The working principle and usage process of the present utility model:

[0044] When the connecting rod 5 rotates to adjust the angle, at this time, start the driving motor 6, which will cause the rotating shaft 7 to drive the rotating block 8 to rotate, and then cause the round shaft 9 to rotate and drive the T-shaped block 10 to move downward, so that the toothed plate 11 moves downward and separates from the outer surface of the gear 12. At this time, the gear 12 is released from the fixed effect. Pull the connecting rod 5 to rotate and adjust the angle with the movable shaft 4 as the axis. When the angle of the connecting rod 5 is adjusted, start the driving motor 6 again, which will cause the toothed plate 11 to move upward and engage with the gear 12 to fix the connecting rod 5, ensuring the stability of the connecting rod 5 after rotation and not easy to shake, and further ensuring the stability of the lighting angle of the lighting lamp 16.

[0045] When blocking the light emitted by the illuminating lamp 16, first pull the handle 22 upward, which will compress the spring 21 and drive the bolt 23 upward. When the bolt 23 moves to the outside of the rotating shaft 18, the fixing effect on the baffle 19 will be released. Then pull the baffle 19 to rotate 90 degrees and release the handle 22. Under the elastic force of the spring 21, drive the bolt 23 to move downward and insert it into the inside of the rotating shaft 18 to fix the baffle 19, so that the baffle 19 can stably block the light emitted by the illuminating lamp 16 and prevent the light from directly shining into the patient's eyes.
