Description

Spray head for small road mark scraper

The utility model belongs to the accessory-shower nozzle of the small-scale workshops machinery that the above highway of secondary, airport, parking lot etc. are located to rule outside urban road, the city.

Use the shower nozzle on the line-marking vehicle at present because structure is undesirable, nozzle is not closed completely, and the coating weeping is often arranged, when needing to draw dotted line, two solid line partition strips often have a fine line to occur, make the whole graticule utmost point not attractive in appearance, obstructed when spraying paint continuously, nozzle easily stops up, often drawing several kilometers long line need clear up repeatedly, bring many troubles to the staff, speed is slow, and efficient is low.

The purpose of this utility model is to be to overcome above-mentioned existing problems, designs a kind of gases at high pressure that utilize and overcomes spring force and the opening valve push rod, and make coating after fully atomizing under the effect of gases at high pressure, evenly is sprayed on the road surface with certain pressure.

The utility model is to realize with following technical proposal: this small-sized road line marker shower nozzle, has a valve body (11), the steel seat (12) that push rod (10) is housed in valve body (11) and is slidingly matched with push rod (10), rubber base (13), spring (14), spring abutment (15), sealing ring (16), threaded block (17), the upper end of push rod is provided with top stem casing (31), be pressed with spring (30) on the top stem casing (31), six squares (22) and push rod cap (20) are arranged in one to be threaded, wherein be pressed with cylindrically coiled spring (19) on the push rod cap, one shoulder lid (25) is arranged in the upper end of spring, it and sliding joining of connecting ring (21) are connected on the valve body (11), the top of shoulder lid (25) is provided with top cover (23), has spring (24) to be positioned at the top cover lower end; The lower end of valve body (11) connects an inner ring (3) by another connecting ring (21), be provided with in the inner ring (3) band conical surface valve core case (9) and with the inner ring sliding fit, nozzle (4) is connected on the inner ring (3) by a little chain of rings (2), be provided with outer ring (1) in the periphery of mouth (4), the both sides of outer ring (1) connect a baffle plate (5) by bolt respectively; Upper air inlet port A, its next into lacquer mouth B that is provided with of being provided with of valve body (11).

Advantage of the present utility model, because this shower nozzle appropriate design and be used with special paint can, so the air velocity height of shower nozzle ejection can wash out the floating dust on ground, making has good adhesion stress between the coating of ejection and ground; The thickness of coating spray-up (line thickness) can be regulated by top cover 23, and is easy to adjust and scope is bigger, applicable to various line requirements; The breakdown action of valve push rod is stablized, is not shaken, and guarantees the even of line; Among the design valve push rod 10 and valve core case 9 be by conical surface slit by coating, so that the aperture of valve core case 9 bottoms can be done is bigger, has guaranteed the nozzle operation smoothness, be difficult for stopping up from structure like this.

Description of drawings of the present utility model;

Fig. 1 is the utility model master pseudosection.

Fig. 2 is the utility model partial cut away side views.

Be described in further detail below in conjunction with 1,2 pairs of structures of the present utility model of accompanying drawing and operating principle thereof:

Shown in Figure 1, the steel seat 12 that valve push rod 10 is housed in valve body 11 and is slidingly matched, rubber base 13, spring 14, spring base 15, sealing ring 16, threaded block 17 with it, push rod again with thread connection in top stem casing 31, the axial location of push rod and top stem casing is finished by screw 32, is pressed with spring 30 on the top stem casing 31.In six squares 22 and push rod cap 20 with thread connection, be pressed with cylindrically coiled spring 19 on the push rod cap, the upper end of spring is that shoulder cover 25, shoulder cover 25 and connecting ring 21 slide and join, and by coupling ring with thread connection on valve body 11.Top cover 23 is pressed in spring 24 to take on to cover on 25 and with shoulder and covers 25 with thread connection, as shown in the figure: the lower end of valve body links with inner ring 3 by another connecting ring 21, and an end of valve core case 29 is the conical surface, and the conical surface sliding fit of inner ring 3 and valve core case 9.21 position-limiting actions of 8 pairs of connecting rings of jump ring.Little connecting ring 2 among the figure is threadedly connected to nozzle 4 on the inner ring 3, and is shown in Figure 2: outer ring 1 is connected by stove bolt 29, and the baffle plate 5 of both sides shown in Fig. 1,2 is connected on the outer ring 1 by bolt 6.Be provided with two gas passage I, II in the valve body 11, be provided with air inlet port A outside the valve body 11, advance a lacquer mouthful B.This shower nozzle can be connected on the support of shower nozzle by bolt 27 grades by junction plate 26, and support links to each other with connecting rod, bolt etc. with car load again.During not operation, unclamp connecting bolt, this shower nozzle just can be taken down separately.

The utility model is when the line operation, high pressure gas in the gasholder, a part is shown in Figure 2 by air inlet port A() enter valve body 11, with the air flue I in the valve body 11, II communicates, high pressure gas just acts on the lower surface of push rod cap 20, when atmospheric pressure during greater than the pretightning force of spring 19, push rod cap 20 just is being with valve push rod 10 to move up, the gap appears between valve push rod 10 and the valve core case 9, and coating is shown in Figure 2 by advancing lacquer mouthful B(under the effect of charging basket internal pressure) enter in the circuit between valve push rod 10 and the valve core case 9, in case the gap occurs between valve push rod 10 and the valve core case 9, lacquer is just by spraying in the aperture of this gap by valve core case 9 bottoms.Because valve core case 9 and inner ring 3 are with cone match, so the effect of blanket gas is arranged, therefore the high-voltage air-gap that enters in gas passage I, the II plays outside the effect of opening valve push rod 10, also have the part high pressure gas to enter between valve core case 9 and the inner ring 3 by four radial slots on valve core case 9 conical surfaces, before lacquer jetting nozzle 4, will coat with lacquer fully and just spray to ground after the atomizing.Rubber base 13 plays gasket coating being pressed on the steel seat 12 under the effect of spring 14, prevents that coating from scurrying into epicoele.Sealing ring 18 can prevent that high pressure gas from scurrying into epicoele.In addition, the high velocity air of ejection also can wash out the floating dust on ground, there is the other shower nozzle of good adhesion stress to be provided with two baffle plates 5 between the coating of feasible ejection and ground, can guarantee the neat the utility model work of the profile of ruling unimpeded, be difficult for to stop up, valve push rod breakdown action is sensitive and do not shake the low (4kg/cm of operating pressure ²About) both made more local operation the business district pedestrian, also very safe.
