Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 show schematically show a kind of adjustable nozzle according to one embodiment of the present invention.
As shown in Figure 1,2 and 3, this adjustable nozzle comprises head body 1, a pair adjustable nozzle part 2, governor motion and return springs 3.In addition, protective sleeve 4 and seal 5 is also comprised.
For hollow forms water containing chamber 101 in head body 1, its bottom has the water inlet 102 be communicated with water containing chamber 101, and top has the delivery port 103 be communicated with water containing chamber 101.Head body 1 top has two symmetrically arranged dash protuberances 104.A pair adjustable nozzle part 2 to be articulated with between two dash protuberances 104 by jointed shaft 6 and to be symmetrical arranged, and two dash protuberances 104 and a pair adjustable nozzle part 2 surround adjustable nozzle 7.Adjustable nozzle 7 is communicated with delivery port 103.Governor motion is connected with a pair adjustable nozzle part 2, for regulating this to the opening degree of adjustable nozzle part 2.Return springs 3 is connected with adjustable nozzle 2, resets for driving this adjustable nozzle part 2.Protective sleeve 4 is placed on the outside of adjustable nozzle part 2 and dash protuberance 104.Seal 5 is between adjustable nozzle part 2 and dash protuberance 104.
Governor motion can be automatic adjusting mechanism, also can be manual adjustment means.In the present embodiment, be manual adjustment means, particularly, governor motion comprises taper adjusting portion 201, external screw thread 105 and regulating part 8.
Taper adjusting portion 201 is positioned on adjustable nozzle part 2.External screw thread 105 is positioned in head body 1.
As shown in Figure 4, regulating part 8 comprises adjusting nut 801 and the ejection part 802 be located on adjusting nut 801.Adjusting nut 801 is by being threaded rotatable blackout in head body 1 with external screw thread 105.Ejection part 802 and taper adjusting portion 201 are connected, and rotate for promoting adjustable nozzle part 2.
Specifically, be exactly by rotating adjusting nut 801, adjusting nut 801 moves axially along head body 1, and then drive ejection part 802 to move axially along head body 1, change the link position of ejection part 802 and taper adjusting portion 201, and then promotion adjustable nozzle part 2 rotates, and realizes the adjustment of exchanging nozzle member 2 opening degree to.Make governor motion functional reliability strong, simple and compact for structure thus.Can not only effectively regulate the water spray range of a kind of adjustable nozzle of the present invention, and low cost of manufacture, be convenient to installation and transportation, practicality is stronger.In addition, regulated by adjusting nut 801, degree of regulation is higher and be convenient to regulate, and adjustment operation is convenient, and governing speed is fast.
In the present embodiment, for the ease of rotating adjusting nut 801, prevent the problem causing being difficult to turn adjusting nut 801 owing to skidding from occurring, the outer surface of adjusting nut 801 has annular knurl 803.Effectively ensure that the stability that adjusting nut 801 works thus.In other embodiments, the outer surface of adjusting nut 801 can be have groove or anti-skidding salient point.
In order to protect adjustable nozzle part 2 and dash protuberance 104, protective sleeve 4 is socketed on that this both outside, effectively avoid thus adjustable nozzle part 2 and dash protuberance 104 easily frayed, extend service life.Protective sleeve 4 is fixedly connected with dash protuberance 104.As illustrated in Figures 5 and 6, protective sleeve 4 top has the spout 401 corresponding with adjustable nozzle 7.Return springs 3 one end is connected with protective sleeve 4, and the other end connects adjustable nozzle part 2.Make a kind of adjustable nozzle compact conformation of the present invention thus, volume is light and handy, is convenient to install and use and transport.
Protective sleeve 4 can be metal protection protector or plastic protective sleeve, in the present embodiment, is metal protection protector, is specially copper protective sleeve.Copper has higher corrosion resistance, and durability is better, and service life is longer.Meanwhile, copper has the gloss of flicker, goodlooking, can play decoration function well.
Seal 5 is between adjustable nozzle part 2 and dash protuberance 104.Make thus to be formed between adjustable nozzle part 2 and dash protuberance 104 to seal, effectively prevent seepy question.
Seal 5 can be sealing gasket or sealing ring.In the present embodiment, be sealing ring, be specially sealing ring.As shown in FIG. 7 and 8, adjustable nozzle part 2 has annular groove 202, seal 5 is fixedly sleeved in annular groove 202.Effectively can ensure the sealing between adjustable nozzle part 2 and dash protuberance 104 thus.
Head body 1 can be copper nozzle body or zinc-containing alloy head body.In the present embodiment, be copper nozzle body, copper has higher corrosion resistance, and durability is better, and the advantage that service life is longer, which thereby enhances the service life of head body 1.
Adjustable nozzle part 2 can be copper adjustable nozzle part or zinc-containing alloy adjustable nozzle part.In the present embodiment, be copper adjustable nozzle part, copper has higher corrosion resistance, and durability is better, and the advantage that service life is longer, which thereby enhances the service life of adjustable nozzle part 2.
Return springs 3 can be spring, elastic protecting sleeve or shell fragment.Can select according to actual needs.In the present embodiment, be shell fragment, be specially spring steel plate.Spring steel plate has good elasticity, higher fatigue strength and enough toughness and plasticity, good operating stability and service life longer, improve the practicality of a kind of adjustable nozzle of the present invention.
When a kind of adjustable nozzle of the present invention uses, water inlet 102 is communicated with feed pipe, and the water in feed pipe flows through water inlet 102, water containing chamber 101 and delivery port 103 successively, finally sprays from adjustable nozzle 7.When needing to carry out the adjustment of water spray range, by rotating adjusting nut 801, adjust the opening degree of a pair adjustable nozzle body 2, achieve the adjustment of adjustable nozzle 7 size, and then achieve the adjustment of water spray range.Such as, when needs spray more nearby, upwards revolved by adjusting nut 801, adjustable nozzle 7 becomes large, and the water now penetrated is fan-shaped.When needs spray remotely, the water at this moment penetrated becomes linear, and by adjusting nut 801 to backspin, adjustable nozzle 7 diminishes, and can be mapped to target place in time.Adjustable Range is 1 ~ 15m.Use safety and easy to adjust.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
