Abstract

PURPOSE:To make it possible to secure safety, in an airless painting gun, by surrounding the region exposed to the danger of a high pressure paint within the spray region from nozzle chip by a shelf shaped hand guard comprising a narrow plate material or a wire material. CONSTITUTION:A hand guard 1 shows a shelf shape (a) formed by bending a narrow plate material or a wire material and has a space 2 in the spray expanse direction of a high pressure paint while forming gaps 3 each having a width not passing a finger to both sides thereof and mounted to a gun main body 7 by inlaying the same with the inner peripheral groove of a nozzle presser 11 by a grasping frame part 5. By this mechanism, safety is secured by a shelf shaped hand guard 1 and the amount of the paint adhered to the guard is reduced to generate no paint dripping as well as the surface of an object to be painted is not roughened. In addition, because of the shelf shape, a tool such as spanner can be mounted through the gaps 3 and the positional determination of a nozzle chip 9 can be also performed without detaching the guard 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The X invention relates to an airless can hand card device disposed in front of a nozzle tip from which high-pressure paint is ejected.

General VC, the airless spray method that applies high pressure to the paint and sprays it from a small nozzle tip (atomizing nozzle) to atomize it. It is used.

But 2 normal te 100KVCrll, K case 2
o Because the paint is injected at a high pressure exceeding 0Kfcrd, the speed of the paint reaches 500 kyn per hour immediately after being injected, and its handling is potentially dangerous. When using this spray, be careful not to have your hands near the injection nozzle (VC) or to avoid spraying it towards two people, but even the slightest carelessness could lead to an accident, so it is safer. The device is desired.

Conventionally, several VCs have been proposed for this type of card. For example, take a card like No. 1 + VC with a nozzle/L that removably fixes the spray can VC and has two plate-like walls arranged on both sides. , Masa et al. 1978-9780
The injection shown in No. 7.

It has plate-shaped walls on both sides that are built into one piece.

However, with these wall-mounted cards (safety devices), there is a lot of paint adhesion to the wall surface, and for this reason, when the VC is used for a long time, the adhered pigment becomes coarse lumps and scatters onto the painted surface, causing stains on the mounting surface. The result is Ding.

Also, paint adhering to the opening of the injection nozzle can be seen.
It is dangerous to look in from the front, and the result is extremely unfavorable.

Furthermore, in the former example, it is difficult to adjust the direction of the pattern sprayed from the spray nozzle, and it is difficult to align the nozzle because it is necessary to predict the position where the nozzle will be fixed in advance and tighten the nozzle holder. . In the latter case, where the injection nozzle and the card are integrated, alignment is easy, but even within the range of normal use, there are more than 50 types depending on the amount of ejection and turn width of the injection nozzle. It would be extremely wasteful and impractical to prepare a card with such a card attached to it.

In view of the current situation, it is an object of the present invention to provide an inexpensive and highly safe end card device that does not cause any trouble with the IC for painting work.

That is, the X invention is a hand card shaped to be placed in the dangerous area in front of the injection area by suitably bending or σ punching a narrow plate material or a wire material such as wire, and the hand card is detachably attached to an airless can. and paint adhesion and paint dripping, l″1
．． To provide a hand card device that is easy to position and does not cause problems.

Hereinafter, the invention will be explained with reference to the drawings of the embodiments as follows.

This is a hand card in the form of a fence formed by bending a plate material (or wire material) with a narrow iVJ width, and the hand card 1 is configured with a fully open 2 in the direction in which the spray spreads.

Maintaining a gap 3 to the extent that fingers cannot fit on both sides in the direction orthogonal to the whole question 2, it presents a loaf fence shape a, and the base H, 4X
The pillar part 4 is easy to attach a positioning wrench to, and is provided with a clamping frame part 5I/C for connecting the two left and right pillar parts 4, and an arcuate groove 6 for fitting into the nozzle retaining part. 7 days without rest,
The nozzle base 10 of the injection nozzle 9 is positioned at the tip of the needle valve 8 of this Kofu fC insertion, and the injection nozzle 9
is locked by a nozzle holder 11vc screwed onto the nozzle base 10vc. 12 is a nozzle opening.

Next, when attaching this hand card 1 to the force/main body 7 side, a circular arc groove 6.6 having a pinching frame portion 5.5 at the base end of the hand card 1 is carved with a nozzle holder 11i'C. The VC is fitted into the circumferential groove 18FC.

Here, when positioning the injection nozzle 9 (the injection nozzle 9 is fixed at 71fC with the nozzle holder 11, the nozzle holder 11 rotates by tightening the screw, so the injection nozzle 9 also rotates 1). (The position will be irregular. Therefore, positioning is performed by rotating only the injection nozzle 9 after fixation.) 9 For example, as the most commonly used means, a monkey spanner A is used as shown by the two-dot chain line in Fig. 5. As shown in the figure, position the FC node card 1 by sandwiching it across the parallel surface of the injection nozzle 9, and rotate only the node card 1 after -f. The position of the nozzle card L is also aligned with the injection direction of the injection nozzle 9.

After that, a predetermined paint spraying operation is performed, and in this case, the tip of the spray nozzle 9 4 vc transfer hand card l
It is made of board material or wire rod and has only a minimal shelf-like shape, and the area where the paint adheres is larger than the conventional wall-forming hand card. There is almost no turbulence and the paint flows along the jet stream from the rear of the side, further reducing the amount of paint being deposited. turbulence occurs and paint tends to adhere).

As described above, the hand card of the airless can hand card device of the present invention has a safety structure in which the hand card is made of a narrow plate material or wire VC and has a shelf-like shape as a whole with the space between the sheets arranged in the spray spreading direction. As a result, less paint adheres to the card, and therefore the paint does not drip, and the surface of the object to be coated is not roughened. Also, since the card is a fence as a whole, it is possible to attach tools such as spanners, and the positioning of the chip can be done with a knife. Moreover, it can also be worn with conventional injection nozzles. Of course.

Since this guard member is made of steel and spring wire, it has sufficient strength and has the effect of improving V'C after long-term use.
