Abstract
The utility model provides a flexible spraying rod with a valve for a sprayer. The utility model is composed of a switch and the spraying rod. The switch is provided with an inner and an outer sleeve pipes that are mutually sheathed, and a seal water ring is arranged between two sleeve pipes for sealing. A steel ball is arranged between an inlet pipe and a joint of an inner connecting pipe for sealing. The spraying rod is composed of a big, a middle and a small spraying rods that are mutually sheathed, both ends of the sleeve pipe and the joint are provided with screw threads. The sleeve pipes are sealed by the seal water ring. The utility model has the advantages of simple structure, small movement of the atomizing switch, small wear-out and good sealing effect. When the flexible spraying rod with the valve is used, an angle is rotated lightly. The flexible spraying rod is not easy to grind or leak, the appearance is beautiful, the flexible spraying rod can be retracted or extended, and the carryover and use are all very convenient.
Description
The utility model relates to a kind of sprayer, the movable spray boom of especially a kind of belt switch of sprayer.
The spray boom of sprayer use at present has the long weak point that has; but its length is fixed substantially; the change of can not following one's bent; and in the practice of construction operation; regular meeting runs into needs long spray boom sometimes, need the situation of short spray boom sometimes; but inconvenience all is with several spray booms at every turn, and long spray boom carries very inconvenient.Spray switch is wearing and tearing easily then, often leak.
The purpose of this utility model provide a kind of simple in structure, activity bit is little, the switch of good seal, and the length of can stretching portably uses the movable spray boom of belt switch easily.
The utility model comprises switch and spray boom two partly, and the technical scheme of being taked is:
Spray switch has two internal and external casings that are nested (1,4), and inner sleeve two ends and outer tube one end are separately fixed on the joint (5), and water shutoff circle (2) sealing is arranged between two sleeve pipes (1,4), establishes a steel ball (3) envelope position between inlet tube and inner connecting tube joint.Spray boom is nested and is formed by three large, medium and small loop bars (6,10,11), and nipple one end is fixing with screw (9), and gasket seal (8) is set, and the two ends of sleeve pipe and joint all have screw thread, also seal with water shutoff circle (7) between sleeve pipe.
The utility model is not simple in structure, and the spray switch activity bit is little, and it is little to wear and tear, and water shutoff circle contact-making surface is big, and good sealing effect only need rotate an angle to get final product gently during use, and is easy to wear and leak, and good looking appearance.The spray boom of collapsible elongation portably uses all very convenient.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model spray switch partial structure schematic diagram.
Fig. 2 is the utility model spraying spray boom partial structure schematic diagram.
The utility model connects spray boom by spray switch and forms.Copper pipe of spray switch outer appearance, two ends are pipe joint (5), the middle part is two internal and external casings that are nested (1,4), inner sleeve (4) two ends are fixed on the nipple, and it is unfixing that outer tube (1) one end is fixed an end, and pad is all put in sleeve pipe and joint, water shutoff circle (2) sealing is arranged between two sleeve pipes, establish a steel ball (3) envelope position between inlet tube and inner pipe joint, one on switch connects spray boom, and one connects flexible rubber hose.Its operation principle is: the just and then elongation or shrink of swivel and outer tube, inner sleeve, the pressure that adds external liquid medicine promotes steel ball and holds out against or leave, and makes liquid medicine enter pipeline or dams, and forms open and close.
The profile of spray boom and TV, wireless active pull rod antenna are similar.By three outer, in, lining sleeve pipe (6,10,11) is nested and forms, nipple one end is fixed with screw (9), and gasket seal (8) is set, the two ends of sleeve pipe and joint all have screw thread outward, also seal with water shutoff circle (7) between sleeve pipe.Connection switch of spray boom, a dress shower nozzle.Its operation principle is that liquid medicine only passes through from little tube hub when three loop bars complete sets are lived, and other paths are shut by water seal, and spray boom is when the quarter butt use; When needing long distance to spray medicine, tubule, middle pipe are pulled out one by one, rotation is fixing, can form long spray boom.
