Description
Technical field
The utility model belongs to liquid spraying technique field, is specifically related to be used for cranny filler of polyurethane foam spray gun thimble aperture adjusting device.
Background technology
Because the PU foam gap filler has functions such as fixing, sound insulation, insulation, waterproofing and leakage-stopping, it obtains using more and more widely at building field.In operating process, be equipped with spray gun usually and reach the purpose that is implemented into each target accurately and efficiently.
Existing commercially available spray gun, its aperture governor motion ubiquity potential safety hazard, accommodative excess very easily causes unexpected ejection of foam gap filler or harm operator's personal safety.There is defective in its structure, does not have caution sign again, and needing has strict requirement to operation.
Summary of the invention
For overcoming the defective that spray gun core bar aperture governor motion in the prior art has potential safety hazard, the purpose of this utility model be to propose a kind of simple in structure, easy to assembly, guarantee in the reasonable aperture scope of thimble and the thimble aperture adjusting device that can unexpected not get loose and make.
For reaching the goal of the invention the technical solution adopted in the utility model be:
The thimble aperture adjusting device of foam gap filler spray gun, comprise gun body, place the gun barrel of gun body front end, the nozzle of gun barrel front end, thimble and trigger with control and regulation gap filler flow, thimble is positioned at gun barrel by slider support and slides, trigger and the interlock of thimble slide block, it is characterized in that the thimble rear end connects the push rod that is with holddown spring, but the push rod rear end is the screw rod of by-pass cock and locking thimble and regulates nut, be provided with screw rod retaining ring between screw rod and the adjusting nut, between holddown spring roof pressure slide block and the screw rod, screw rod advances as spiral in gun body or retreats, and the going-back position of screw rod is limited by screw rod retaining bar.
Described screw front end has pit, is the rotation steel ball in the pit, and screw rod screws in the rifle body to screw thread and rifle body end face or slightly recessed.Frictional resistance when reducing the screw rod adjusting rotates lighter;
Further, the rear end of described screw rod is inserted and is regulated in the nut deep hole,
Described retaining ring set is connected to screw rod bar portion, and the endoporus aperture is less than the nominal diameter of screw flight.
The thimble aperture adjusting device of foam gap filler spray gun compared to existing technology, its beneficial effect is:
(1) simple in structure, spacing by retreating of adjusting screw(rod) is set, guarantee that thimble is can only be in the reasonable aperture scope of design movable and can unexpected not get loose and cause injury to the operator; Effectively solve the potential safety hazard of prior art spray gun core bar aperture governor motion.
(2) adjusting nut is connected with screw rod is dismantled and assembled, has reduced because of adjusting nut and screw rod injection moulding concentricity difference and has scrapped, and has improved production efficiency.
Figure of description
Fig. 1 is the utility model nozzle arrangements schematic diagram.
Among the figure: 1 is Adjusting bolt Adjusting screw; 2 is screw rod; 3 is the retaining ring; 4 is steel ball; 5 is holddown spring; 6 is push rod; 7 is the thimble slide block; 8 is adapter; 9 is gun barrel; 10 is nozzle; 11 is thimble; 12 is sealing device; 13 is trigger.
The specific embodiment
Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these specific embodiment.One skilled in the art would recognize that the utility model contained in claims scope all alternatives, improvement project and the equivalents that may comprise.
The thimble aperture adjusting device of foam gap filler spray gun, comprise gun body, place the gun barrel 9 of gun body front end, the nozzle 10 of gun barrel front end and the thimble 11 and the trigger 13 of control and regulation gap filler flow, thimble 11 supports by thimble slide block 1 and is positioned at the slippage of the gun barrel left and right sides, trigger and the interlock of thimble slide block.Adapter 8 is positioned at rifle body top, is the inlet of gap filler; Gun barrel 9 is fixed in the front end of rifle body, quickens gap filler and flows; 10 nozzles are positioned at the front end of gun barrel, are the outlets of gap filler; Thimble 11 is used for the switching of nozzle, is provided with between the outlet of adapter 8 and the thimble slide block to prevent the excessive sealing device 12 of gap filler.
The operator is by the flow of trigger 13 controls and adjusting gap filler.
The thimble rear end connects push rod, and holddown spring is socketed in push rod, and the holddown spring roof pressure is between slide block and retaining pressure ring.But the push rod rear end is the screw rod 2 of by-pass cock and locking thimble and regulates nut 1, screw rod retaining ring 3 standing screw rear ends, also can be placed in screw rod is fixed on the rifle body, screw rod advances as spiral in gun body or retreats, the drive push rod moves forward and backward, and the going-back position of screw rod is limited by screw rod retaining bar.
Adjusting bolt Adjusting screw 1 is positioned at the afterbody of spray gun; After screw rod is connected, regulate aperture and locking thimble, screw rod 2 is positioned at the Adjusting bolt Adjusting screw front portion, and the rear end inserts in to be regulated in nut 1 hole, and both are that removable structure connects.Steel ball 4 places in the pit of screw front end, and the frictional resistance in the time of can reducing the screw rod adjusting rotates lighter;
The operation principle of the utility model spray gun is:
Gap filler enters the rifle body by adapter 8, is full of till the nozzle 10 through gun barrel 9 always, and this moment is cocking 13 backward, and trigger just drives thimble slide block 7 and slides backward.Because thimble 11 and thimble slide block 7 are fixed together, when thimble slide block 7 slided backward, thimble 11 also and then moved together backward, and this moment, nozzle 10 places reserved the space, and gap filler sprays immediately.
Assembly that earlier thimble 11, thimble slide block 7 and push rod 6 is linked into an integrated entity during installation and holddown spring 5 shown position of packing into successively from right to left, then the screw rod 2 of putting into steel ball 4 is screwed in the rifle body, until screw thread and rifle body end face or slightly recessed, then retaining ring 3 is penetrated the rear portion of screw rod 2, and it is fixing, again Adjusting bolt Adjusting screw 1 is inserted screw rod, last and screw rod 2 is fixed.
The utility model is by screwing in or screw out the aperture that Adjusting bolt Adjusting screw 1 is regulated push rod 6, and when Adjusting bolt Adjusting screw 1 screwed in, the aperture of push rod 6 reduced gradually, contacts with push rod 6 up to steel ball 4.This moment, thimble 11 complete and nozzle 10 inwalls applyings were in closed condition, and Adjusting bolt Adjusting screw 1 has played the locking effect.When Adjusting bolt Adjusting screw 1 withdrawed from backward, the aperture of push rod 6 increased gradually, and the Adjusting bolt Adjusting screw 1 of this moment works to regulate aperture.Because the position-limiting action of retaining ring 3, screw rod 2 is run into retaining ring 3 back Adjusting bolt Adjusting screws 1 just can not continue rotation, screw rod 2 just can't shrink back again, thereby just avoided breaking away from spray gun and causing thimble 11 not reset, caused the unexpected ejection of foam gap filler and be in state out of control because of screw rod 2 excessively withdraws from.
In addition, owing to screw rod 2 does not directly contact by steel ball 4 transition with holddown spring 5, resistance when having reduced adjusting, feel is free and relaxed.
