0, and a decorative panel 41 is provided on the lower side of the indicators 28, 29, 30 so as to be detachable with a key 42,
A part of the decorative panel 41 is cut out, and the nozzle hook 31,
32 and 33 are provided. In addition, the nozzle hook 31,
An operation switch mechanism 51 is arranged on the decorative panel 41 above the upper part 32, 33.

FIG. 2 is a horizontal sectional view of an operation switch mechanism according to the first embodiment of the present invention, and FIG. 3 is a side view illustrating a protection plate portion according to the first embodiment of the present invention. The parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

In these figures, the operation switch mechanism 5
1 is a nozzle hook 3 provided on the front side of the main body case 16.
The decorative panel 4 is arranged so as to face the opening 16a of the main body case 16 close to the opening 3 and covers the opening 16a.
1, a switch pressing portion 53 attached via a switch cover 52, and a support 54
And a protection plate 57 for protecting the front of the operating portion 56 of the microswitch 55.

The switch cover 52 is formed of plastic or the like, and is formed in a lid shape straddling the periphery of the upper part of the nozzle holder 33. Openings 52a for attaching two switch pressing parts 53 are formed on the left and right sides. ing. The switch cover 52 is fixed to the decorative panel 41 with screws 58 from the back side.

The switch pressing portion 53 is a cylindrical case 53a having a flange at one end and a shaft hole at the other end.
A shaft 53b one end of which protrudes slightly outward to freely slide through a shaft hole of the case 53a, and the other end of which protrudes slightly toward the flange through the inside of the case 53a;
A spring 53c, which is housed in the housing and biases the shaft 53b toward the flange portion, a push button 53d mounted on one end of the shaft 53b with a screw, and is slidably mounted on the other end of the shaft 53b. A switch pressing piece 53e,
A spring 5 housed in the switch pressing piece 53e and biasing the switch pressing piece 53e out of the shaft 53b.
3f and the sliding of the switch pressing piece 53e along the axis 53b by engaging with the axial slit 53g formed in the switch pressing piece 53e provided on the side surface of the switch pressing piece 53e on the end side of the shaft 53b. And a locking portion 53h for limiting the distance to a predetermined distance B. This switch pressing portion 53
Is formed by passing the outer portion of the case 53a through a hole 41a formed in the decorative panel 41, and pressing the push button 53d through the opening 52.
a, the flange portion of the case 53 a contacts the back surface of the switch cover 52 and is fixed with screws 59.

The micro switch 55 has an operating part 56
Is attached to the switch pressing portion 53 at a position facing the switch pressing piece 53e. And the protection plate 57
As shown in FIG. 3, the two plates are formed so as to be rotatable by a talking plate, and one plate is fixed to the upper surface of the microswitch 55 with a screw 60 or the like, and the other plate is placed in front of the operating unit 56 by its own weight. Has been placed. That is, the switch pressing piece 53e of the switch pressing section 53 is separated from the end face by a distance A from the end face to the protection plate 57.

In the operation switch mechanism 51 having the above structure, first, in order to operate the micro switch 55, the push button 53d of the switch pressing portion 53 is pushed by hand against the urging force of the spring 53c to move the shaft 53b from the case 53a. The end face of the switch pressing piece 53e provided on the shaft 53b is moved by a distance A to abut against the protection plate 57, and further pressed to move the operating portion 56 a necessary distance via the protection plate 57. The micro switch 55 operates. When the operating portion 56 is pushed beyond a required distance, the switch pressing piece 53e is pressed against the shaft 53 against the urging force of the spring 53f.
Slide b to the distance of B and push button 53d more than necessary
Is pressed so that a force that damages the operating portion 56 is not applied. When the hand is released from the push button 53d, the shaft 53b is pushed back by the urging force of the spring 53c, the switch pressing piece 53e retreats, and the operating portion 56 returns to the original state.

Next, the decorative panel 41 unlocks the key 42 and opens the key 42 toward the front, so that the switch cover 52 and the switch pressing portion 53 are fixed to the decorative panel 41.
It can be easily removed from the main body case 16. Further, the decorative panel 41 is provided with the opening 16 a of the main body case 16.
And can be attached by locking the key 42. When the decorative panel 41 is attached, the distal end of the switch pressing piece 53e does not directly contact the operating portion 56 with a certain distance A, and a protective plate 57 is provided on the front surface of the operating portion 56. The switch pressing piece 53e
Does not collide with the operating portion 56 and is not broken.

FIG. 4 is a horizontal sectional view of an operation switch mechanism according to a second embodiment of the present invention. 2 and FIG. 3 are denoted by the same reference numerals.

In the figure, a switch pressing portion 62 of an operation switch mechanism 61 is provided with a lock which can be operated only by a predetermined person in charge, and has the same shaft 53 as in the first embodiment.
b instead of the push button 53d at the tip of
A push button 66 with a lock operated by a key 65 is provided on an adapter 64 fixed to a by a screw 63. The switch pressing section 62 can be held in a state where the operating section 56 is operated by operating the key 65 and pressing the push button 66. Other parts are the same as in the first embodiment.

In each of the above-described embodiments, the example in which the switch pressing portions 53 and 62 are fixed to the decorative panel 41 via the switch cover 52 has been described.
It may be directly fixed to. Further, the protective plate 57 is not limited to the shape of the embodiment as long as it is formed in a shape that protects at least the operating portion 56.

[0021]

As described above, according to the present invention, since the switch pressing portion is fixed to the panel of the main body case of the lubricating device, the attachment / detachment becomes simple while the switch pressing portion is fixed to the panel, and This has the effect of not damaging the switch.
