Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning support for an air turbine bur, which is a cutting tool for dental care.

[Conventional technology]

BACKGROUND OF THE INVENTION Air turbine burs (hereinafter simply referred to as burs) used by dentists and the like to sharpen teeth become dirty at their tips and need to be cleaned. As an example of cleaning, an ultrasonic cleaner may be used, but if the bar is placed directly into the cleaner, it will be difficult to take out and handle, so a support may be used.

FIG. 7 shows an example of such a cleaning support, in which a large number of insertion holes 12 for bars 8 are arranged in parallel on a base 2 in which legs 21 are formed by bending both sides of a plate. The support plates 1 are provided at intervals with a cylindrical body 6 interposed therebetween, and bolts 7 inserted from above the support plate 1 are passed through the cylindrical body 6 to attach the base 2.
The end of the bolt 7 is made to protrude from the bottom surface and is tightened with a washer and nut 5, and the tip of the bar 8 inserted through the insertion hole 12 is supported on the surface of the base 2.

During cleaning, a large number of insertion holes 1 provided in the support plate 1 are used.
A plurality of bars 8 are inserted into 2 and placed in a washer to be cleaned.

[Problems that this invention attempts to solve]

When the ultrasonic cleaner operates, the deposits on the bar will accumulate on the support plate.
After removing the cleaning support from the washer, it was necessary to wash the support plate by running water, which was troublesome.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a cleaning support for an air turbine bar that is clean and requires no effort for cleaning without collecting deposits on the cleaning support even when cleaned with an ultrasonic cleaner.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention is an air turbine bar cleaning support device in which a support plate with a number of bar insertion holes is provided on a base at intervals, and the support plate is arranged in a row of insertion holes in the support plate. Make a slit along the
The gist is that the top surface of the base is made of a net.

[Effect]

According to the present invention, the deposits separated from the bar during cleaning descend onto the base surface through the slits provided along the row of insertion holes in the support plate, and pass through the holes in the net of the base. , descending to the bottom of the washer tank.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the air turbine bar cleaning support of the present invention, in which 1 indicates a support plate;
The support plate 1 is formed smaller than the base 2 described above, has screw holes 11 at its four corners, and has a large number of 12 rows of bar insertion holes arranged at appropriate intervals in the center of the support plate 1.

Then, slits 13 were provided in the longitudinal direction along the 12 rows of insertion holes. Note that this slit 13 may be provided in the lateral direction of the row of insertion holes 12. The insertion hole 12 was formed obliquely so that the tip of the bar approached the slit.

Further, a U-shaped member 31 with the end protruding to the back surface crushed is attached through the hole at the center end of the support plate 1, and a U-shaped handle 3 with the tip bent inward is attached to the U-shaped member 31. .

A cylindrical body 4 provided with small diameter screws 41 at both ends was screwed into the screw hole 11 of the support plate 1 from the back side, and the other end was connected to the base 2.

The base 2 has legs 21 formed by bending both sides of a flat metal plate downward, and an opening 22 provided on the top surface.
A mesh body 23 with a mesh smaller than the diameter of the bar is provided in the opening 22.
It is attached by welding from the back side.
By providing holes 24 at the four corners of the base 2, inserting the screws 41 of the cylindrical body 4 into the holes 24 from the front surface, making them protrude from the back surface, tightening them with nuts 5, and further caulking the protruding ends of the screws 41. The nut 5 is prevented from loosening even when an ultrasonic cleaner is operated.

Note that the support plate 1, the base 2, and the net body 23 are made of a corrosion-resistant and rust-resistant metal such as stainless steel.

Next, to explain how to use it, insert the bar into the insertion hole 12, support the lower end with the base 2, set a large number of bars on the cleaning support, hold the U-shaped handle 3, and apply the ultrasonic waves to the cleaning support. Place it in the washer and turn on the washer.

The upper end of the bar inserted into the insertion hole 12 is located above the slit, and the lower end is located below the slit. When the cleaning device is operated, the deposits on the surface are removed, and the deposits on the top end of the bar are not accumulated on the support plate 1. slit 1
3 onto the base 2, and the deposits at the lower end continue to descend, but since the top surface of the base 2 is a mesh 23, it passes through the mesh and accumulates at the bottom of the tank of the washer.

Furthermore, the net body 23 is also cleaned by ultrasonic waves, and the cleaning support itself is also cleaned along with the bar.

After cleaning, tilt the U-shaped handle 3 to either the left or right (the handle 3 can be tilted both left and right),
By inserting the bar into the cleaning support and covering it with a box lid 9 with an open bottom as shown by the chain line in FIG. 4, it can be protected from dust and the like and kept in a clean state.

When using the bar, it is necessary to remove the lid 9 and take out the bar, but as an example, as shown by the chain line in Fig. 5, the box body serving as the lid 9 can be turned over and used as a stand. It is also possible to place the cleaning support so that the end edge thereof is sandwiched between the nut 5 protruding from the back surface of the leg portion 21 of the base 2.

As another example, although not shown, in addition to the above, it is also possible to fix the cylindrical body to the support plate and the base by welding or the like without using screws at both ends of the cylindrical body. A plate or the like may be used instead.

Further, the legs of the base may be fixed to another member, and may be provided around the entire periphery of the base, or may be provided only at the corners. Furthermore, the overall shape of the cleaning support may be triangular or polygonal in addition to the rectangular shape, in which case a support plate, base, or box body suitable for these shapes is used.

[Effect of idea]

As described above, according to the air turbine bar cleaning support of the present invention, slits are provided along the row of insertion holes in the support plate, and the deposits separated from the bar during cleaning are passed through the slits and mesh. As a result, it falls to the bottom of the tank of the washer, preventing deposits from accumulating on the cleaning support.

In addition, the cleaning support of the present invention has slits in the support plate and a net in the base, so it is lighter and easier to handle than before, and has many openings.
Along with cleaning the bar, the slits of the support plate and the mesh of the base are also easily cleaned by the ultrasonic waves, and the cleaning support tool taken out from the washer is cleaned together with the bar, which saves time and effort.
