Description

[Detailed explanation of the invention] As a conventional dental laboratory cabinet, for example,
5-47536 and 56-1033, can be rotated upwards to close the work space when not working, and rotated forward to close off the necessary equipment when working. etc., are pulled out to the front.

In dental technology, especially in wax-up work, burners must be used to melt wax.

However, the conventional burner described above is flexible and is attached to the tip of the gas pipe so that it can be moved freely on the workbench, making it difficult to determine its position.

Workers had to choose a suitable vacant place to go on vacation, and their posture gradually deteriorated, resulting in fatigue and inaccurate work during long hours of work.

Moreover, since a torch or the like was used to ignite the ignition, it was inefficient as the ongoing work had to be interrupted.

Therefore, the present invention aims to provide a dental laboratory cabinet that allows gas to flow only in a fixed position and automatically ignites the burner, thereby stabilizing the worker's posture and at the same time improving work efficiency.

An embodiment of the present invention will be explained below with reference to the drawings.
Reference numeral 1 denotes a dental laboratory cabinet, and 2 a workbench, which are connected so that they can be bent by a hinge 3 at the middle between the front and back.The workbench 2a located at the back is fixed to both side plates 4, 4, and the workbench 2a is located at the front side. The workbench 2b is configured to be able to rotate upward to close the work and storage space 5.

A holding part 6 for a rotary cutting tool is provided at the front edge of the front workbench 2b, and a part 7 for holding a wax pan used for wax-up work is provided on the back workbench 2a.

An air suction base pipe 8 and a gas pipe 9 are installed above the workbench 2a located at the back, and a suction pipe 10 connected to the air suction base pipe 8 so as to be rotatable in the front and back direction is attached to the air suction base pipe 8. It is configured so that a suction action is applied when it is pulled out to the work point P on the front workbench 2b.

Similarly, a branch pipe 11 connected to the gas pipe 9 so as to be rotatable in the front-rear direction is attached, and a gas burner 12 is provided at the tip of the gas branch pipe 11.

The structure of the connecting part of the branch pipe 11 to the gas pipe 9 is shown in FIG. When the communication hole 16 of the bottomed cylindrical body 14 matches, the gas flows toward the burner 12 side.

The connecting pipe 13 has a projection 17 as a stopper.
A protruding piece 18 is also provided on the top surface of the bottomed cylindrical body 14 so that the branch pipe 1
An automatic ignition device 19 is incorporated in the protrusion 18, and when the branch pipe 11 is pulled out to the working point P, which is the limit position in the forward direction, the gas is released from the burner. 12 and at the same time, the protrusion 1 enters the ignition device 19.
The burner 12 is automatically ignited by contacting the burner 7 and generating sparks at the burner nozzle.

20 is a backing for preventing gas leakage.

Next, the structure of the burner 12 provided at the tip of the branch pipe 11 will be explained with reference to FIG. 4. 21 is a gas flow rate adjustment cock, 22 is an air intake adjustment screw, 23 is a burner nozzle, and 24 is a stable position for holding the burner 12. This is a support that is installed on the top surface of the workbench 2 in order to do so.

In the above embodiment, the branch pipe 11 was rotated in the horizontal direction, but if the connecting pipe 13 is tilted, the tip burner part can be lowered when pulled out in the same way as the suction pipe 10, and lifted upward in the storage position. .

As explained above, the dental laboratory cabinet of the present invention is a cabinet in which the front workbench of the workbench is divided into front and back parts, and the workbench on the front side can be rotated upward so that the opening can be closed. A gas pipe is installed in the space of
A rotatable branch pipe with a burner at its tip is connected to the front from this gas pipe, and an automatic ignition device is installed in this branch pipe to allow gas to flow through the branch pipe and ignite the burner at the pull-out limit position. Since it is configured to operate, if the branch pipe located at the back of the workbench is pulled out to the front drawer limit position, that is, the work point, gas will flow and automatically ignite.

Therefore, there is no need to interrupt wax-up work and ignite it with a matchstick or the like every time the wax-up work is done, as is the case in the past, and efficiency is significantly improved.

In particular, according to the present invention, the burner cannot be used because gas does not flow anywhere other than the workbench, which is the limit position for drawing out the branch pipe.
It is not possible to place the burner at an appropriate location on the workbench and perform work as in the past.

Therefore, the worker must necessarily position the burner at a designated work point while working, maintaining a natural working posture and reducing fatigue even during long hours of work.
