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 aperture adjusting device.
Background technology
Functions such as that the PU foam gap filler has is fixing, sound insulation, insulation, waterproofing and leakage-stopping, thereby the PU foam gap filler particularly 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.But the aperture governor motion ubiquity potential safety hazard of present spray gun: this mechanism is usually located at the end of caulking gun, adopt threaded screw rod to regulate the aperture of spray gun, safety measures such as caution sign or stopping means are not set, in use exist because of shortcoming and defect such as the potential safety hazard of regulating the improper accidental bodily injury who causes and assembling, adjusting efforts.
Summary of the invention
Spray gun aperture governor motion does not have stopping means in the prior art in order to overcome, have the defective of potential safety hazard, the purpose of this utility model be to propose a kind of simple in structure, easy to assembly, aperture is easy to adjust and limit the aperture adjusting device of the foam gap filler spray gun of operating range by the rifle body.
For reaching the goal of the invention the technical solution adopted in the utility model be:
The 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 slides in gun barrel, its front end contacts with nozzle inner walls, the rear end of thimble is fixed on the screw rod, it is characterized in that adjusting nut hollow, have and the suitable internal thread of the external screw thread of screw rod, the rifle body is provided with the qualification face of delimiting adjusting nut displacement effective range in the both sides of adjusting nut, rifle body end screws in the rifle body with screw, the spiro rod rear end connection is with preloading spring, between preloading spring roof pressure screw rod and the screw.
Described adjusting nut outer ring is designed to increase the lines of nut rotation feel.
Described rifle body is provided with cavity at corresponding adjusting nut place, and the top of adjusting nut is positioned at cavity, and the cavity two sides be for delimiting the qualification face of adjusting nut displacement effective range.
Described cavity upper side is provided with the rule of the mark trigger anglec of rotation or spray gun aperture.
The aperture adjusting device of foam gap filler spray gun compared to existing technology, its beneficial effect is:
(1), simple in structure, adjusting device is arranged on spray gun middle part, the scope of activities of adjusting nut is limited by the rifle body, can not cause the injury to the operator, effectively solves the potential safety hazard of prior art spray gun core bar aperture governor motion.
(2), because the pretightning force of cylindrical spring in the foam gun does not directly act on the adjusting nut, can easily rotate adjusting nut, and can realize one-handed performance.
(3), because the Flow-rate adjustment of foam gun is to realize by the distance of adjusting adjusting nut and rifle body mid portion, in case after distance was between the two determined, the flow of foam gun just determined that also rifle body flow can both be consistent when allowing the different operating person use.
(4), only play the function of preloading spring behind the screw of the spray gun end screw-in rifle body.The adjusting of aperture relies on rifle body middle part, and limited adjusting nut is realized on one's own initiative.Avoided in regulating use, the potential safety hazard of the unexpected ejection of blowing agent, flown away from that thing is hurted sb.'s feelings or lack situation such as cause that spray gun is scrapped because of flying away from part.
(5), because screw no longer possesses the function of locking, simplified screw-rod structure and length, saved cost.
Description of drawings
Fig. 1 is the utility model nozzle arrangements schematic diagram;
Fig. 2 is the partial schematic diagram of adjusting and retaining mechanism.
Among the figure: 1 is adjusting nut; 2 is screw rod; 3 is the rifle body; 4 is cylindrical spring; 5 is screw; 6 is trigger; 7 is thimble; 8 is sealing device; 9 is nozzle; 10 is gun barrel; 11 is adapter.
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 aperture adjusting device of foam gap filler spray gun, comprise the nozzle 9 of the rifle body 3 that holds each functor, the gun barrel 10 that places the gun body front end, gun barrel front end, the thimble and the trigger of control and regulation gap filler flow, thimble slides in gun barrel, its front end contacts with nozzle inner walls, the rear end of thimble is fixed on the screw rod 2, screw rod 2 is positioned at the middle part of rifle body, rises to connect thimble and guide effect; Nozzle 9 is positioned at the front end of gun barrel, is the outlet of gap filler; Sealing device 8 is in the rear end of gun barrel, and is excessive to prevent gap filler.Adapter 11 is positioned at rifle body top, is the inlet of gap filler.Adjusting nut 1 is used to regulate aperture, lock nut and thimble, and adjusting nut is the hollow nut, has and the suitable internal thread of the external screw thread of screw rod.The flow of gap filler is controlled and regulated by adjusting nut to trigger.
The rifle body is terminal to screw in the rifle body with screw 5, and the connection of screw rod 2 rear ends is with preloading spring 4, between preloading spring 4 roof pressure screw rods and the screw.
The adjusting nut outer ring is designed to increase the lines of nut rotation feel.
The operation principle of the utility model spray gun is:
Gap filler enters the rifle body by adapter 11, is full of till the nozzle 9 through gun barrel 10 always, and this moment is cocking 6 backward, and trigger 6 just drives screw rod 2 and slides backward.Because thimble 7 and screw rod 2 are linked together, when screw rod 2 slided backward, thimble 7 also and then moved together backward, and this moment, nozzle 9 places reserved the space, and gap filler sprays immediately.
Introduce the operation principle of aperture governor motion in detail below in conjunction with accompanying drawing:
State shown in the accompanying drawing 2 is a normal operating conditions, and when rotation adjusting nut 1 was mobile backward, adjusting nut 1 reduced gradually with the left side spacing of rifle body 3 mid portions, and up to contacting with rifle body 3, adjusting nut 1 has played the locking effect.When rotation adjusting nut 1 moved forward, adjusting nut 1 increased gradually with the left side spacing of rifle body 3 mid portions.Can in setting range, control the angle of pulling of trigger 6 as required arbitrarily, thereby reach the purpose of adjusting.In this rotary course, adjusting nut 1 plays the effect of regulating aperture again.No matter adjusting nut 1 is to move forward or backward, all can only be movable in the effective range that trigger 6 and rifle body 3 are set between the two, thus can avoid effectively causing the unexpected security incident that sprays of foam gap filler because of accommodative excess.In addition, because cylindrical spring 4 does not directly act on adjusting nut 1, feel is very free and relaxed when making installation, adjusting.
The utility model adjusting nut can rotate adjusting nut and realize its moving axially on screw rod by being threaded on the screw rod, thereby adjusts the spacing of itself and rifle body, and then the anglec of rotation of control trigger.And the scope of activities of adjusting nut is set in the effective scope, thereby guaranteed its reliable security and serviceability.
