2. Description of the Related Art FIG. 3 is a schematic view of an essential part for explaining an example of a method for injecting maintenance oil for a dental handpiece head, which is currently performed. In the figure, 10 is a micro engine, an air turbine, etc. , A head part 11 is attached to the tip of the hand piece for dental treatment, and as is well known, by pushing the lid member 12 of the head part 11, the chuck mechanism in the head part 11 is pushed. Is opened, the cutting bar (cutting tool) 13 is inserted, and the pressing force of the lid member 12 is released, so that the inserted cutting bar 13 is stopped. Reference numeral 20 denotes a spray can for injecting maintenance oil into the handpiece 10. The spray can 20 has a nozzle 21, and the tip of the nozzle 21 is provided on the connection side of the handpiece 20, for example, air. If it is a turbine, insert it into the opening 14 of the air supply pipe, push the oiling plug (spray plug) 22 of the spray can,
The maintenance oil in the spray can 20 is supplied to the head portion 11 through the inside of the handpiece 10 to supply the bearing and the like in the head 11. However, when the handpiece 10 is for a micro engine, the nozzle 21 is used after being replaced with one having a shape suitable for the connecting portion of the hand piece for a micro engine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic configuration diagram of a main part for explaining an embodiment of an oiling device for injecting maintenance oil into a dental handpiece head according to the present invention, and FIG. 2 is an exploded configuration diagram thereof. In the figure, 31 is a cylindrical protective cover, 31
Reference numeral a denotes a groove provided in a side portion of the protective cover 31 in the axial direction (vertical direction), and the head portion 11 of the handpiece 10 is inserted into the protective cover 31 through the groove 31a, and
It can be moved up and down. Reference numeral 32 denotes an oil filler member, and the oil filler according to the present invention basically comprises the protective cover 31 and the oil filler member 32. In addition, as an accessory, the oil can (spray can) 20.
Is equipped with an oil receiver 33 for receiving the sprayed oil flowing down through the oil supply can 20, and an adsorption member 34 for adsorbing the oil jetted upward through the inside of the head 11. Good.

More specifically, according to the present invention, the cylindrical protection with an open lower portion is provided with the head portion 11 of the dental handpiece 10 and has a groove 31a capable of pressing the head portion 11 downward. The cover 31 and the lubricating can 20 on which the protective cover 31 is placed are disposed on the upper part of the can 20, and
Through-hole 3 into which an oil-filling plug protruding above the oil-filling can is inserted
2a and a ring-shaped oil inlet port member 32, and the head 11 is passed through the groove 31a and the protective cover 31.
The head 11 part by positioning the head 11 part on the through hole 32a of the oil fill port member 32 arranged in the upper part of the oil filling can 20 and pressing the head 11 part downward. Then, the oil supply plug 22 of the oil supply can 20 is pressed to inject the oil in the oil supply can 20.

That is, according to the present invention, when pouring the maintenance oil into the head 11 of the dental handpiece 10, the oil can 33 or a tissue paper, a dust cloth, or other oil-absorptive member (spray can) is placed on the oil-absorbing member. 20 is placed thereon, and the oiling plug (spraying plug) 22 of the spray can is placed so as to be surrounded by the opening 32a of the oil filling port member 32, and then the handpiece 10 is placed in the opening 32a of the oil filling port member 32.
11 of the heads are aligned and then the protective cover 31
After that, the handpiece 10 is pushed downward and the head 11 of the handpiece 10 pushes the oiling plug 22 of the oiling can 20 to inject the oil in the oiling can 20. At that time, that is, when the oil injection plug 22 is pushed to release the valve, the opening 32a of the oil injection port member 32 is closed by the head portion 11, so that the injected oil is effectively introduced into the head 11.

The oil sprayed from the lubrication can 20 is transferred to the head 1
It is injected into the head portion 11 through a hole provided in one portion of the lid member 12 or a gap (for example, a screwing portion) in the attachment portion of the lid member 12, and is ejected from the opposite surface through the inside of the head portion 11. (Note that although FIG. 1 illustrates an example in which oil is supplied from the lid member 12 side, oil may be supplied from the opposite surface, that is, the cutting bar mounting side). The upper portion of the protective cover 31 has a closed structure so that the sprayed oil does not scatter into the atmosphere, but the sprayed oil travels along the inner wall of the protective cover 31 and then falls, and then the oil filler member. Since it falls through the groove 32b provided on the outer peripheral wall of 32 and the groove 31b provided on the lower surface of the protective cover 31 and further along the outer wall of the oiling can 20, the lower part of the oiling can 20 has the above-mentioned structure. It is advisable to spread an oil absorbing material such as the oil pan 33 or tissue paper. Also,
If the adsorbent 34 is provided on the inner surface of the upper portion of the protective cover 31, the amount of oil that drops will be reduced and post-finishing will be easier.

In addition to the above, the lubrication can 20 is used at the time of use.
An example has been described in which the lubrication port member 32, the handpiece 10 and the protective cover 31 are sequentially arranged on the top of the above, and then the handpiece 10 is pushed downward, but the lubrication can 20, the lubrication port member 32, the protective cover 31, etc. Is integrated in advance, and at the time of maintenance (at the time of lubrication), the protective cover 31
It is also possible to insert the head portion 11 of the handpiece 10 through the groove 31a and to push the head portion 11 downward to lubricate.

[0013]

As is apparent from the above description, according to the present invention, the maintenance oil can be efficiently injected into the head portion of the dental handpiece with a simple and inexpensive structure and a simple operation. be able to.
