Abstract

The utility model belongs to an atomizer fitting, in particular to a manually-operated spray gun of an atomizer, which adopts the proposal that a spray guard is connected at the front end of a spray rod, and a gun casing is connected at the rear end; a core bar is installed in a spray rod pipe; a water inlet interface is arranged at the bottom of the gun casing; the core rod is sleeved at the tail end of a lever bracket hinged with the gun casing; a high-pressure resistant independent pipeline is arranged in the gun casing, and the pipeline respectively communicates with the water inlet interface and the spray rod. The high-pressure resistant independent pipeline is arranged in the gun casing, thereby the gun casing is not impacted by high pressure, the pressure resisting and sealing requirements do not exist, the installation can be performed through screws, and the processing difficulty is reduced; the offsetting spring of the core rod props against the inner surface of a three-way pipe, so that no squeezing action is applied to the gun casing, and the gun casing is not easy to break; the independent pipeline is composed of metal pieces which are connected through screw thread, the installation is simple, the operation is reliable, and the pressure resisting strength is large; a knob is installed at the rear part of the core rod, and the adjustment is convenient.

Description

Sprayer is pulled the formula spray gun

Technical field:

The utility model relates to sprayer accessory, particularly sprayer and pulls the formula spray gun.

Background technology:

The formula spray gun of pulling is installed on high-pressure sprayer, and its rifle shell front end and spray boom spiral shell connect, and the bottom is fixed with into water interface, and rifle shell inner chamber constitutes pipeline will intake interface and spray boom connection.Spray boom is a hollow tubular, and movable core bar is housed in the pipe, and the spray boom front end connects tubaeform spray cover, and spray boom, core bar and spray cover joint form valve; Trigger piece top and rifle shell flexibly connect, and middle and lever dolly is hinged, and the lever dolly other end is connected with the core bar that is with back-moving spring, and trigger piece location turn-knob swivel nut is in spray boom.The trigger piece of holding with a firm grip moves after driving lever dolly and driving core bar, the back core bar under the effect of spring of the loosing one's grip reach that resets, and aforesaid operations can change the valve internal position, the jet length and the shape of adjusting spray gun.The rifle shell of spray gun is the low-intensity working of plastics, and intracavity pipeline is subjected to the high pressure effect for a long time, the aging easily explosion of rifle shell.Rifle shell inner chamber is the High-Pressure Water passage, the sealing property of rifle shell is had relatively high expectations the difficulty of processing height; With spray boom to be connected the frequent dismounting of rifle shell external screw thread very easily damaged, can't continue to use; Back-moving spring on the core bar and spray gun inwall press conflict and break easily, and spray gun uses the back quality problems outstanding, the repair rate height.

The utility model content:

The purpose of this utility model provide have high pressure resistant, reliable in quality, the sprayer of characteristics such as use is easy to adjust pulls the formula spray gun.

Scheme of the present utility model is: its spray boom front end connects the spray cover, the rear end connects the rifle shell, core bar is housed in the boom pipe, rifle shell bottom is provided with into water interface, the lever dolly tail end that is hinged with the rifle shell interlocks core bar, be provided with high pressure resistant independent tubes in the rifle shell, this pipeline is communicated with water inlet interface, spray boom respectively.

Independent tubes in the rifle shell is made of threeway and water inlet pipe, and the threeway front end is connected with spray boom, and the bottom is connected with water inlet pipe, and the water inlet pipe bottom connects the water inlet interface.The rifle shell is by fore shell and back cover combination, and threeway, water inlet pipe, spray boom rear portion and water inlet interface top are clipped between the front and rear casing.Threeway is threaded with spray boom, water inlet pipe, and the water inlet interface is threaded with water inlet pipe, and the junction is by viscose glue or sealing ring sealing.The core bar that afterbody is with spring, sealing ring is plugged in spray boom and the threeway, passes the core bar swivel nut turn-knob of threeway and runs through lever dolly, is connected with nut again.

The utility model has the advantages that: high pressure resistant independent tubes is set in the rifle shell, and the rifle shell needn't be subjected to impacting with high pressure, and no withstand voltage and seal request can be installed by screw, and difficulty of processing reduces; The back-moving spring of core bar supports and bumps in the threeway inwall, and the rifle shell is not had squeezing action, and the rifle shell is cracky not; Independent tubes is made of metalwork, by being threaded, simple installation, use reliable, compressive resistance is big; Turn-knob is installed on the core bar rear portion, and is easy to adjust.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model assembling schematic diagram.

The specific embodiment:

See figures.1.and.2, the front end and the bottom of pulling the threeway 4 of formula spray gun are shaped on internal thread, are connected with spray boom 1, water inlet pipe 5 respectively, and water inlet pipe 5 bottoms are threaded with water inlet interface 6, and the junction seals by viscose glue, constitutes high pressure resistant independent tubes.Core bar 2 is with pad 10, spring 9, pad 11, sealing ring 14 successively, and is inserted in spray boom 1 and the threeway 4, and the spool 2.1 of core bar 2 front ends just is positioned at the valve seat 1.1 of spray boom 1.Spring 9 one ends in the threeway 4 are by pad 11, sealing ring 14 conflict threeways 4 inwalls, and the other end is by the projection of pad 10 conflict core bars 2 outer walls, and sealing ring 14 cooperates with threeway 4 back-end sealings under spring 9 extruding, prevents that water under high pressure from flowing out from threeway 4 rear ends.Spray cover 7 connects with valve seat 1.1 spiral shells of spray boom 1, and spray cover 7, valve seat 1.1 and spool 2.1 junctions constitute the valve of control lance ejection shape.Rifle shell 3 is connected combination with back cover 3.2 by screw by fore shell 3.1, and spray boom 1 rear portion, threeway 4, water inlet pipe 5 and water inlet interface 6 tops are clipped between the two housings.The trigger piece 8 of upper end hinge rifle shell 3 constitutes lever construction with lever dolly 15, core bar 2 afterbodys are shaped on external screw thread, and lever dolly 15 rear ends are shaped on through hole, and core bar 2 thread segments are with turn-knob 12 after passing threeway 4 and rifle shell 3, pass lever dolly 15 through holes again, be connected with nut 13 then.

Pull plate handle 8, by moving behind the lever dolly 15 drive core bars 2, spool 2.1 covers 7 inner chamber catch apart from lengthening with spray, water spray is concentrated, it is far away that range becomes, and rotates turn-knob 12 forward, and turn-knob 12 and rifle shell 3 outer walls are conflicted, spring 9 and the fastening core bar of turn-knob 12 interactions 2 positions, spray configuration is constant.The turn-knob 12 that rotates backward, core bar 2 moves forward under the effect of back-moving spring 9, and spool 2.1 is short with spray cover 7 inner chamber catch distance, the water spray diffusion, atomizing effect is good.

Rifle shell 3 is set up special-purpose high pressure resistant pipeline, and rifle shell 3 inner chambers do not have sealing and high pressure resistant requirement, and two housings can be installed by screw, processes easy.Independent tubes is made of metalwork, by being threaded and using glue sealing, simple installation, big, the dependable performance of compressive resistance; Turn-knob 12 is installed on core bar 2 rear portions, and is easy to adjust, reliable.
