DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-6The utility model provides a technical solution: an illuminating lamp for oral examination, comprising a lamp body 1, a handle 2 is sleeved on the outer side of the lamp body 1, and a handle cover 3 is threadedly connected to the end of the handle 2. The arrangement of the handle cover 3 is convenient for protecting the lamp body 1 to prevent the lamp head from being broken when not in use, and is convenient for carrying. A moving rod 4 is slidably connected in the handle 2, and one end of the moving rod 4 is detachably connected to the lamp body 1. A lamp cover 5 is fixedly connected to the end of the lamp body 1. The arrangement of the lamp cover 5 prevents the lamp head from directly contacting the inner wall of the patient's oral cavity, resulting in mucus contaminated and difficult to clean and disinfect, which affects the service life of the lamp head. A lamp head is installed in the lamp cover 5, and a moving assembly is arranged between the moving rod 4 and the handle 2. The moving assembly comprises a tooth block 6, a limiting block 7, a U-shaped block 8, a fixing block 9 and a spring 10. A receiving groove is opened on the surface of the moving rod 4, and a plurality of tooth blocks 6 are fixedly connected in the receiving groove. The tooth block 6 is triangular, and a movable groove 11 is opened at the position of the handle 2 corresponding to the receiving groove. The inner wall of the movable groove 11 is fixedly connected with a U-shaped block 8 and a fixing block 9. A limiting block 7 is hinged in the U-shaped block 8, and a spring 10 is fixedly connected between the limiting block 7 and the fixing block 9. One end of the limiting block 7 away from the U-shaped block 8 is clamped between two adjacent tooth blocks 6. When the medical staff examines the patient's oral cavity, the lamp body 1 is pulled toward the outside of the handle 2 to drive the moving rod 4 to slide in the handle 2. The moving rod 4 slides to make the limiting block 7 fit on the surface of the tooth block 6 and move. When the limiting block 7 moves and fits on the tip of the tooth block 6, the limiting block 7 rotates and drives the spring 10 to be compressed. When the limiting block 7 continues to move and is between the two tooth blocks 6, the spring 10 automatically extends and drives the limiting block 7 to be clamped between the two tooth blocks 6, fixing the position of the moving rod 4 after movement, fixing the extended length of the lamp body 1, and the lamp body 1 will not shake due to collision during use, and the lamp body 1 will not automatically move toward the inside of the handle 2, thereby improving the convenience of use of the lamp body 1, and the length of the lamp body 1 can be adjusted according to different oral conditions to meet the needs of examining different depths of the oral cavity. The structure is simple and easy to operate.

[0020] Furthermore, a pull rod 12 is fixedly connected to one side of the limiting block 7 close to the movable groove 11, and a round ball 13 is fixedly connected to the pull rod 12. Pulling the round ball 13 drives the pull rod 12 to move toward the outside of the movable groove 11, thereby driving the limiting block 7 to disengage from between the two tooth blocks 6, canceling the restraining force on the movable rod 4, and at this time, pushing the lamp body 1 toward the inside of the handle 2, the lamp body 1 can be moved to the starting position, and the handle cover 3 is covered for easy storage.

[0021] Furthermore, a groove 14 is provided at one end of the moving rod 4, and a connected sliding groove 15 and a card slot 16 are provided on the upper and lower sides of the groove 14 of the moving rod 4. The sliding groove 15 is L-shaped, and the card slot 16 is circular. The width of the card slot 16 opening is smaller than the diameter of the card slot 16. The upper and lower parts of the lamp body 1 are fixedly connected with a card rod 17, and the card rod 17 and the card slot 16 match. The card rod 17 is aligned with the sliding groove 15, and the moving lamp body 1 drives the card rod 17 to move in the sliding groove 15. After one end of the lamp body 1 is placed in the groove 14, the rotating lamp body 1 drives the card rod 17 to be stuck in the card slot 16, and the lamp body 1 can be quickly disassembled and assembled on the moving rod 4, which is conducive to the inspection and maintenance of the lamp body 1.

[0022] Furthermore, sliding grooves 18 are provided on the upper and lower sides inside the handle 2, and sliders 19 are fixedly connected to the positions of the moving rod 4 corresponding to the sliding grooves 18. The sliders 19 are slidably connected in the sliding grooves 18. During the movement of the moving rod 4, the sliders 19 slide in the sliding grooves 18, thereby increasing the movement stability of the moving rod 4 in the handle 2 and preventing the moving rod 4 from completely falling off from the handle 2.

[0023] Furthermore, an ultraviolet disinfection lamp 20 is installed inside the handle cover 3. The ultraviolet disinfection lamp 20 is powered by a power supply provided inside the handle cover 3. When the handle cover 3 is closed and the ultraviolet disinfection lamp 20 is started, the lamp body 1 can be disinfected to avoid cross infection.

[0024] Furthermore, the rear end of the handle 2 is rotatably connected with a hook 21, so that it can be clipped on clothing to carry around or hung at a certain location to prevent loss.

[0025] Working principle: During use, when medical staff examines the patient's oral cavity, they pull the lamp body 1 toward the outside of the handle 2, driving the moving rod 4 to slide inside the handle 2. The sliding of the moving rod 4 causes the limiting block 7 to fit on the surface of the tooth block 6 and move. When the limiting block 7 moves and fits on the tip of the tooth block 6, the limiting block 7 rotates and drives the spring 10 to be compressed. When the limiting block 7 continues to move and is between the two tooth blocks 6, the spring 10 automatically extends and drives the limiting block 7 to be stuck between the two tooth blocks 6, fixing the position of the moving rod 4 after movement, and fixing the extended length of the lamp body 1. The lamp body 1 will not shake due to collision during use, and the lamp body 1 will not automatically move toward the inside of the handle 2, thereby improving the convenience of using the lamp body 1. The length of the lamp body 1 can be adjusted according to different oral conditions to meet the needs of examining different depths of the oral cavity. The structure is simple and easy to operate.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
