[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a photopolymerization device installation stand for removably installing a photopolymerization device used for curing resin with light.

(Prior art) A conventional photopolymerization device used to cure resin with light, for example, when a dentist treats cavities and fills the treatment traces with resin, the third photopolymerization device is used to harden the resin. There is one shown in the figure.

In FIG. 3, reference numeral 10 denotes a container-shaped, substantially rectangular cylindrical gripping portion. At the top of this cylindrical grip part 10,
For example, a glass rod-shaped light guide 12 is provided in which a large number of optical fibers are focused and fixed into one, and a light emitting device (not shown, for example, a halogen lamp, etc.) housed in the cylindrical grip 10 is provided. )
The light is guided to the irradiation position by a light guide 12. The cylindrical grip part 10 is provided with an electric cable 13 for transmitting power from a separately provided power source, and the power source is connected to the connector 1.
3a.

As a part of the cylindrical gripping part 10, 14 is called a head part, and 15 is called a body part. The head portion 14 and the body portion 15 are connected in a substantially L-shape.

By the way, the photopolymerization device is used for a short time during treatment.
Traditionally, the fourth stand has been used as a removable installation stand when taking a break from work to perform other tasks, during breaks between treatments, or when moving the entire device to another location. I found something like the picture.

Figure 4 shows the installation stand for the photopolymerization device, and Figure 4a shows the installation stand for the photopolymerization device.

(Problem to be solved by the invention) In the case of such a structure, when the photopolymerization device is installed for a short time, for example, when stopping during treatment and performing another task, it is difficult to insert and remove the photopolymerization device. It has the advantage of being easy to work with and has good workability.

However, by installing the photopolymerization device on the installation stand, the center of gravity of the installation stand was sometimes shifted toward the photopolymerization device side (leftward in FIG. 2a), resulting in an unstable structure.

Therefore, if the device is installed for a long period of time, for example during breaks between treatments, or if the entire device is moved as a set to another location, there is a risk of the installation stand tipping over or the photopolymerization device falling. There is a risk. In the event that the photopolymerization device falls, the light emitting device (usually a lamp) inside the cylindrical grip,
There was a risk that the light guide 12 would be damaged and the glass would scatter.

(Means for Solving the Problems) The present invention was made in order to solve the above-mentioned conventional problems, and the installation stand for a photopolymerization device according to the present invention has a head and a body that are approximately L-shaped. connected to, and
A cylindrical grip part that accommodates a light emitting device, a rod-shaped light guide provided at the head of the cylindrical grip part that guides light from the light emitting device to the outside, and a rod-shaped light guide for transmitting power to the light emitting device. There is a photopolymerization device installation stand for removably installing a photopolymerization device consisting of an electric cable, and a case that houses a power supply unit for power supply, and a side wall on the upper side of the case from which the photopolymerization device is attached. It has two protruding arm parts for installing the photopolymerization device, and the hole formed by the arm part can grip the head of the cylindrical grip part, and also has a body part. It has a structure that can be gripped, and the tip portions of the two arms have a gap large enough to allow the electric cable to enter and exit, and the vicinity of the protruding portion of the arms on the top surface of the casing is connected to the head of the cylindrical gripping portion. According to the shape of the part,
It is characterized by being somewhat concave than the upper surface.

(Example) Hereinafter, an example of the installation stand for a photopolymerization apparatus of the present invention will be described with reference to the drawings. FIG. 1 shows an installation stand for a photopolymerization apparatus according to the present invention, in which FIG. 1a is a plan view, FIG. 1b is a front view, and FIG. 1c is a right side view.

Reference numeral 20 denotes a housing for housing a power source (not shown) for power supply; 21, 21 are two arms protruding from the sides of the housing 20 for installing the photopolymerization device 1; and 22 is a A power cord for connecting to a commercial power supply, 23 a power switch, 24 a storage box for storing medical supplies and small items, 2
5 is a hole for setting the power cord 22, 26 is a power fuse part, and 27 is a jack for supplying power to the photopolymerization apparatus 1, which is connected to the electric cable 1 of the photopolymerization apparatus.
It has a structure that allows it to be removably fitted to the connector 13a provided at the end of the connector 3.

The power supply section provided inside the enclosure 20 is a commercial power supply.
100V to drive light emitting devices such as lamps,
For example, it consists of a transformer that converts from 12V to 16V, and a stabilized power supply circuit. In addition to the power source, inside the housing 20, there are also a timer for turning on the light emitting device and turning it off after a predetermined lighting time, a buzzer that oscillates at predetermined time intervals (usually every few seconds) while the light emitting device is turned on, etc. A control circuit is also installed to control these using a pre-programmed microcomputer or the like.

Two arms 2 for installing the photopolymer device 1
1 and 21 are protruded from the upper side of the casing 20, for example, in a parallel state, and their tip portions 21a and 21a are formed to face each other, so that the electric cable 13 of the photopolymerization device 1 can enter and exit. There is a certain amount of gap. 21c is a hole formed by the arms 21, 21.

This structure provides the following features when installing the photopolymerization device on the photopolymerization device installation stand.

When installing the photopolymerization apparatus for a short time, as in the conventional case, as shown in Fig. 2a, the light guide 12
It can be installed in the conventional manner with a structure in which the head 14 is gripped from the tip of the head. In addition, when installing the photopolymerization device for a long time, the electric cable 13 provided in the photopolymerization device 1 can be connected to the arm portions 21 and 21.
It is introduced into the hole 21c from the gap 21a, the body part 15 of the photopolymerization device 1 is gripped by the arms 21, 21, and the head part 14 is placed on the upper surface of the casing 20 to stably hold it. I can do it. In this case, if the tip of the light guide 12 comes into contact with the top surface of the casing 20, the photopolymerization device may rattle and move slightly, and since the light guide is in the shape of a glass rod, its peripheral surface or end surface may be scratched or damaged. There is a risk. Therefore, in order to prevent the tip of the light guide 12 from coming into contact with the top surface of the casing 20, the protruding portions 21b of the arms 21, 21 on the top surface of the casing 20 are
It may be formed into a predetermined shape according to the shape of the head of the photopolymerization device. That is, by forming it in a somewhat concave shape than the upper surface, it is possible to prevent slight movement of the photopolymerization device.

According to this structure, when the photopolymerization device is installed on the photopolymerization device installation stand, the center of gravity is not biased and is stably maintained.

(Effects) As detailed above, since the present invention has the above configuration, when installing the photopolymerization device on the photopolymerization device installation stand, it is possible to select from two types of installation structures. In other words, when the dentist stops for a short period of time during treatment to perform another task, the dentist inserts the tip of the light guide 12 into the hole in the arm of the installation table and grasps the head, as shown in Figure 2a. With this structure, the photopolymerization device can be easily installed and removed. In addition, during breaks between treatments, or when moving the entire device as a set to another location, the body of the photopolymerization device can be gripped by the arms of the installation stand. Since the photopolymerization device and the photopolymerization device are stably installed, there is little risk that the installation stand will fall or the photopolymerization device will fall, and the device can be used effectively.
