Abstract

The utility model discloses an LED (light-emitting diode) light source dental drill bending machine with a generator, which comprises a handle, an elbow and a machine head. The machine head comprises a machine head upper cover, a machine head shell, a rolling bearing and a hollow rotating shaft, wherein the rolling bearing and the hollow rotating shaft are arranged inside the machine head shell. A cavity of the handle is provided with a shifting fork head with a fork-shaped opening and the generator sequentially from the end port to the inside of the cavity. The tail part of the shifting fork head is connected with a spindle of the generator by a first transmission shaft. The other end of the spindle of the generator is connected with the spindle of the generator by a second transmission shaft. A third transmission shaft is arranged in a cavity of the elbow. The third transmission shaft is mutually meshed with the second transmission shaft by gears arranged at the end parts of both the third transmission shaft and the second transmission shaft. The generator is provided with a power supply wiring assembly. The power supply wiring assembly is connected with a power supply wire, a rapid connection terminal and an LED lamp wire which are arranged in the cavity of the elbow and LED lamps arranged below the head part of the elbow sequentially. In the structure, the LED lamps are adopted to illuminate, so that the illumination is enough and the LED light source dental drill bending machine is convenient to use and saves power. A needle is assembled and disassembled by adopting a pressing mode, and thus, the LED light source dental drill bending machine can realize easy exchange of the needle.

Description

Carry the led light source dental drill bender of electromotor

Technical field

The dental drill therapy apparatus that odontologist uses, be to link by the power transmission shaft that motor drives in the dental drill bender, thereby drive the car pin and treat operation, existing dental drill bender generally all is to use the auxiliary lamp illumination, do not carry illumination functions, often have the insufficient problem of illumination, thereby prolonged treatment time, influenced therapeutic effect, had much room for improvement.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of novel led light source dental drill bender that carries electromotor is provided, illumination abundance, easy to use, saving electric power, respond well.

The technical solution of the utility model is: a kind of led light source dental drill bender that carries electromotor is provided, comprise handle, elbow and head, described head comprises head upper cover, head shell and inner rolling bearing and hollow rotating shaft thereof, the cavity of handle is from the port to the intracavity, be provided with the fork head and the electromotor of band fork-shaped opening successively, between the afterbody of fork head and the main shaft of electromotor, link to each other with first power transmission shaft, the main shaft other end of electromotor, link to each other with the main shaft of electromotor with second power transmission shaft, be provided with the 3rd power transmission shaft in the cavity of elbow, between itself and second power transmission shaft, with the two end with gear be meshing with each other; Electromotor is provided with the power supply wiring assembly, power lead, fast connecting terminal, the LED lamp lead of itself and elbow intracavity, and between the LED lamp of elbow lower head, connect successively.

The aforesaid led light source dental drill bender that carries electromotor is with travelling gear outside the bottom of hollow rotating shaft, and itself and the 3rd power transmission shaft stretch into the gear that be with the end in the head, are Vertical Meshing; The head upper cover middle part is provided with flexible button, and the top of hollow rotating shaft is set with the three lobe spring center shaft locks that strutted by pressure energy.

The led light source dental drill bender that carries electromotor of said structure carries the illumination of LED lamp owing to adopt, the illumination abundance, and easy to use, save electric power; Adopt pressing type dress pin to get pin, can realize easily changing pin.

Description of drawings

Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.

Fig. 1 is the longitudinal sectional drawing of described utility model;

Fig. 2 is the enlarged elevation figure of head.

The specific embodiment

Referring to Fig. 1, Fig. 2, a kind of led light source dental drill bender that carries electromotor is provided, comprise handle 1, elbow 2 and head 3, described head 3 comprises head upper cover 4, head shell 5 and inner rolling bearing 6 and hollow rotating shaft 7 thereof, the cavity of handle 1 is from the port to the intracavity, be provided with the fork head 8 and the electromotor 9 of band fork-shaped opening successively, between the main shaft of the afterbody of fork head 8 and electromotor 9, link to each other with first power transmission shaft 10, the main shaft other end of electromotor 9 links to each other with the main shaft of electromotor 9 with second power transmission shaft 11, is provided with the 3rd power transmission shaft 12 in the cavity of elbow 2, between itself and second power transmission shaft 11, with the two end with gear be meshing with each other; Electromotor 9 is provided with power supply wiring assembly 13, power lead 14, fast connecting terminal 15, the LED lamp lead 16 of itself and elbow 2 intracavity, and between the LED lamp 17 of elbow 2 lower head, connect successively.Be with travelling gear 18 outside the bottom of hollow rotating shaft 7, itself and the 3rd power transmission shaft 12 stretch into the gear that be with the end in the head 3, are Vertical Meshing.

During work, the revolution that fork head 8 is external, driving first power transmission shaft 10 rotates, first power transmission shaft 10 drives electromotor 9 main shafts, second

power transmission shaft

11,12 rotations of the 3rd power transmission shaft in succession, the 3rd power transmission shaft 12 drives travelling gear 18 immediately and rotates, travelling gear 18 drives the car pin and rotates, and treats operation; Simultaneously, produce electric current by cutting magnetic field when electromotor 9 main shafts rotate, electric current flow to LED lamp 17 through power supply wiring assembly 13, power lead 14, fast connecting terminal 15, LED lamp lead 16, makes LED lamp 17 luminous.
