Description
Technical field
The invention belongs to field of engineering technology, relate to a kind of polyurethane foams makes recruitment
Tool, particularly a kind of foam gun.
Background technology
After in architectural engineering, door frame, window frame are installed, its with leave gap between the walls,
Some equipment, pipeline etc. also can leave gap after installing, and must be filled with filling a vacancy, make
It is smooth or seals.Mostly polyurethane foams is all utilized to fill up at present, this material
Material have easy to use again can the advantage of anti-leakage thermal insulation.Polyurethane foams is packed in pressure
In power tank and and air exclusion, because of its characteristic be when with air contact after understand foamed solidification,
Thus use polyurethane foams blind to need special instrument.
Chinese patent its publication number CN102824977A also provides a kind of foam gun, its bag
Include jet pipe and for the small of the stock gripped for operator, the small of the stock has for fixing tank body
Connecting portion, jet pipe the inner is positioned at connecting portion and can be connected with the feed nozzle of tank body, spray
The small of the stock is stretched out in pipe outer end, the small of the stock has in promoting jet pipe after deforming by applying external force
Hold and make the opening structure that the feed nozzle of tank body is opened, when stopping applying external force opening structure
Can automatically reset and the feed nozzle of tank body is closed.
Can be seen that, although it can control foam gun ejection polyurethane foams.But,
Owing in use trigger can deform, use for a long time and cause fatigue damage, pull
Machine may damage, and trigger and the whole small of the stock are integral structures, cause whole
Bubble rifle damages.Its service life is comparatively short, and use cost is high.
Summary of the invention
It is an object of the invention to the problems referred to above existed for prior art, it is provided that Yi Zhongjie
The foam gun that structure is simple, stability is high.
The purpose of the present invention can be realized by following technical proposal: a kind of foam gun, bag
Include jet pipe and for the small of the stock gripped for operator, the described small of the stock has and sends out for fixing
The connecting portion of bubble tank, described jet pipe the inner is positioned at connecting portion and can be connected with foamed pot,
The small of the stock is stretched out in described jet pipe outer end, it is characterised in that have L-shaped on the described small of the stock
Spanner, described spanner one end for pulling end, the other end for top pressure side, in above-mentioned spanner
Portion is hinged on the small of the stock and pushes up pressure side and is resisted against jet pipe the inner, pulls when applying external force
During end, above-mentioned top pressure side is along with jet pipe being promoted after swinging inner and make tank body open.
This foam gun is for being sprayed the polyurethane foams in foamer pressure tank by jet pipe
Go out.Specifically, operator applies finger and pulls spanner, and spanner swings around its hinged place,
It is to say, after pulling end stress, top pressure side applies pressure on top surface to jet pipe the inner.Due to
Jet pipe moves relative to foamer pressure tank, so that the polyurethane in foamer pressure tank
Foaming agent is ejected by jet pipe.
After injection, stop pulling end applying external force, at the work of foamer pressure tank
By lower jet pipe homing, also returned to initial position by the squeezing action spanner of jet pipe.
In above-mentioned foam gun, the described small of the stock has the articulated section of protrusion, above-mentioned pull
