Abstract

An embedded metal spray gun comprises a gun body, gun body protective colloid, an inner water pipe, a spray head, a water control mechanism and a spanner; a metal water inlet interface connected with the lower port of the inner water pipe is embedded in the lower part of the gun body; the water inlet interface can be shaped as a multi-step annular tube whose tube diameter of the upper extreme is equal to that of the inner water pipe; the external surface of the inlet water interface is the coarse surface and is pressed together with the gun body; an inner joint can be arranged inside the water inlet interface; the inner joint is provided with a convex rang which has rabbet joint with the water inlet interface; the inner joint and the inner water pipe adopt ultrasonic welding; an external enclosure meshed with the external surface of the gun body is arranged outside the water inlet interface. The embedded metal spray gun of the utility model adopts single metal water inlet interface which is embedded or welded into the plastic gun body through ultrasonic wave so as to improve the durability of the spray gun and increase the level of the spray gun.

Description

The metal damascene spray gun

Technical field

The utility model relates to a kind of garden supplies, particularly a kind of metal damascene spray gun to the plant water spray.

Background technology

Gardening water pistol rifle body all adopts all-metal rifle body or overall plastic spray gun body, because of the high institute of metal price so that the gardening spray gun is durable, attractive in appearance, but cost is big, the price height; Though and plastics water pistol cost is lower, people's the plastic product of sensation in idea class is lower, the outward appearance shortcoming, and service life is short, is easy to damage.

The utility model content

For remedying above-mentioned deficiency, the utility model provide a kind of key position with metal make, durable metal damascene spray gun.

The utility model metal damascene spray gun comprises that rifle body, rifle body protect glue, inner conduit, fountain head, draining machine structure and spanner, wherein: the water inlet interface that is embedded with the lower port that connects inner conduit in described rifle body bottom.

The utility model metal damascene spray gun, wherein: described water inlet interface is that many steps are annular tube shaped, and its caliber and described inner conduit topmost is equal to, and described water inlet interface outer surface is a matsurface, with the pressing of described rifle body.

The utility model metal damascene spray gun, wherein: in the described water inlet interface nipple is arranged, the interlocking of bulge loop and described water inlet interface is arranged on the described nipple, and described nipple and described inner conduit adopt ultrasonic bonding, and described water inlet interface has the outer encirclement that coincide with described rifle external surface outward.

The utility model metal damascene spray gun, the water inlet interface that has adopted independent metal to make embeds or inserts in the plastics rifle body with supersonic welding, has improved the durability of spray gun, has also increased the class of spray gun.

The specific embodiment

For further setting forth the utility model metal damascene spray gun, do more detailed explanation below in conjunction with embodiment.

Fig. 1 is the schematic diagram of the utility model metal damascene spray gun first scheme, therefrom can see, the utility model metal damascene spray gun by rifle body 1, rifle body protect glue 2, inner conduit 3, water inlet interface 4, draining machine structure 5, fountain head 8, spanner 7 is formed.

Wherein rifle body 1, inner conduit 3 usefulness engineering plastics are made; The rifle body protects glue 2 and adopts rubber to make; Cover 5 adopts plastic electroplating in spanner 13 and the nozzle, and draining machine structure 5 is that metal adds rubber, and fountain head 8 adopts plastics, metal, rubber mix to make, and water inlet interface 4 adopts metal to make.

With the spray gun of above-mentioned parts, the visible Fig. 1 of its concrete structure.In rifle body 1, inner conduit 3 makes progress sideling from the bottom of handle, extends forward to rifle body rear portion folding is flat; The front end of inner conduit 3 connects draining machine structure 5, and draining machine structure 5 the place aheads connect fountain head 8; Rifle body 1 rear portion is provided with spanner 7, and the extension of this spanner 7 and draining machine structure 5 is connected; With the Kai Heguan of spanner 7 control draining machine structures 5, and then realize the control that fountain head 8 is sprayed water; The lower end of inner conduit 3 connects metal system water inlet interface 4, water inlet interface 4 is the annular tube shaped (see figure 3) of step more than, and in the direct injection gun body, its upper end diameter is identical with inner conduit 3 diameters when injection moulding rifle body 1, lower end diameter is corresponding with external water pipe, uses for connecting outer water tube; Owing to adopt the separate piece design, water inlet interface 4 adopts metal to make, and this has all improved the durability and the class of spray gun.

Fig. 2 is another kind of structure.Also has a nipple 6 in the water inlet interface 4, there is an annular protrusion (see figure 4) nipple 6 lower ends, chimeric with water inlet interface 4, the diameter of this nipple 6 is identical with inner conduit 3, both contact-making surfaces adopt ultrasonic bonding, one outer encirclement 9 is arranged below the water inlet interface 4, be exposed at the outside of rifle body 1 and the outer contour of rifle body 1 and match.Outer encirclement 9 parts of the water inlet interface 4 that this exposes had both increased the durability of spray gun, had increased the attractive in appearance of spray gun again.

Main parts such as rifle body still adopt plastic production, this not only reduced spray gun cost, but also alleviated the weight of spray gun, it is more handy to use.
