Abstract

The utility model relates to a running water cleaning spray gun, which is a spraying device with cleaning effect with spraying liquid, comprising a jet tube and a handle which are connected as integration, and the inner parts of the jet tube and the handle are mutually communicated and are provided with a hollow structure. A flow control rod is arranged in the jet tube, the front end of the flow control rod is provided with three column sections whose cross sections are different and are transited via a cone station, and the back end extends out of the jet tube and is connected with position nuts. A trigger hinged on the handle is clamped on the position nuts, and the front end of the jet tube is screwed with a nozzle body. The utility model overcomes the defects of complicated structure and unreasonable design of the existing cleaning spray gun and can be used with being connected to a running water pipe, and therefore, the utility model has convenient use.

Description

Running water cleaning spray gun

A kind of running water cleaning spray gun relates to injection apparatus, particularly reaches the injection apparatus of cleaning performance by atomizing of liquids.

In the occasion of water cleaning of objects, as cleaning automobile, train, steamer, generally be to adopt flexible pipe to connect running water to wash during excavating equipment, perhaps the mouth of pipe at flexible pipe connects a nozzle, to form stronger impact current.Yet the injection direction of current and shape are difficult to control in this way, cause inconvenience to use.Chinese patent 91229385.3 discloses a kind of injecting type cleaning device, is made up of body, plate machine, push rod, sealing frame, sealing-plug, sliding sleeve etc.It moves the back push rod by holding the plate machine by sliding sleeve, screw transmission power vertically, and hydro-peening liquid sprays from apopore.After removing out, hand is closed condition again.Though this injecting type cleaning device can be realized becoming with flow area, the effect that the flow of water, range, jet angle also change thereupon.But still have the shortcoming that member is many, structure is unreasonable, and use also inconvenient.

The purpose of this utility model is to propose a kind of running water cleaning spray gun simple in structure, reasonable in design, easy to use.

For achieving the above object, the utility model adopts such technical scheme, and the rifle body is made of jet pipe that fuses and handle.All there is opening at the two ends of jet pipe, front opening and nozzle body bolt.Control stream bar is installed in jet pipe, and described control stream bar front end is first cylinder, carries out the transition to second cylinder through the frustum of a cone then, and second cylinder carries out the transition to three cylindrical through the rounding frustum.And the radius of three cylindrical is greater than first cylinder, and first cylindrical radius is greater than second cylinder.The tail end of control stream bar is spirally connected with positioning screw cap after stretching out the opening of jet pipe rear end.Inside in the jet pipe rear end is with sealing ring and back-up ring on the control stream bar successively.Be with spring on the control stream bar between three cylindrical and the back-up ring.And, the apopore diameter on the nozzle body less than the diameter of three cylindrical greater than second body diameter.Water stream channel for communicating in the handle with jet pipe.The plate machine is hinged on the handle by bearing pin, and its top is stuck on the positioning screw cap.

The utility model compared with prior art not only has advantage simple in structure, reasonable in design, easy to use, and applied widely in addition, makes simply, need not the characteristics of pressure pump.

Accompanying drawing is the utility model generalized section.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in drawings, the inside of jet pipe (2) and handle (1) is the hollow structure that is interconnected, and jet pipe and handle fuse.All there is opening the rear and front end of jet pipe, its front opening and nozzle body (3) bolt of taking the water hole out of.Control stream bar (9) is housed in jet pipe.The tail end of control stream bar stretches out from the jet pipe rear end and positioning screw cap (14) bolt.Be hinged on the plate machine (16) on the handle (1) by bearing pin and be stuck on the positioning screw cap.The top of plate machine preferably is processed into zigzag and is formed teeth (13), so that match with the locating ring that is connected the jet pipe rear portion (12) control stream bar is positioned.Deviate from order to prevent positioning screw cap from becoming flexible, on the plate machine, be processed with the catch (15) of retaining behind positioning screw cap.The front end of control stream bar is first cylinder (14), carries out the transition to second cylinder (5) through the frustum of a cone, and second cylinder carries out the transition to three cylindrical (6) through the rounding frustum.On three cylindrical, preferably be processed with guide vane (7), to guarantee that controlling stream bar front and back on the axis of jet pipe moves.And the diameter of three cylindrical is greater than first cylinder, and the diameter of first cylinder is greater than second cylinder.The diameter in nozzle body upper water-out hole greater than first cylinder less than three cylindrical.Certainly, the side that is positioned at jet pipe inside at nozzle body preferably is equipped with gasket seal.Inside in the jet pipe rear end is with sealing ring (11) and back-up ring (10) on the control stream bar successively.The control that spring (8) is enclosed between back-up ring and the three cylindrical is flowed on the bar.When the plate machine is in relaxed state, oppressed forward because bar is flowed in the whole control of the effect of spring, thereby the rounding frustum between the three cylindrical and second cylinder is pressed on the gasket seal, apopore is sealed.The while spring is also oppressed back-up ring is pressed on the jet pipe open rearward end sealing ring, also the jet pipe open rearward end is sealed.When the plate machine is pulled, pull back control stream bar by positioning screw cap, rounding frustum and gasket seal are disengaged, water sprays from apopore.Along with not having no progeny of bar of control stream moved, the different variation also takes place in the current shape of apopore ejection.

Claims

1, a kind of running water cleaning spray gun includes the jet pipe and the handle that fuse mutually, is hinged on the plate machine on the handle and is contained in the interior control stream bar of jet pipe, and the jet pipe front end is bolted with nozzle body, and the water stream channel for communicating with jet pipe in the handle is characterized in that:

A. control stream bar front end is first cylinder, carries out the transition to second cylinder through the frustum of a cone, carries out the transition to three cylindrical through the rounding frustum again, and the injection diameter on the nozzle body greater than second cylinder less than three cylindrical;

B. control stream bar tail end stretches out the jet pipe open rearward end, and with the positioning screw cap bolt, the top of plate machine is stuck on the positioning screw cap;
