Abstract
The utility model belongs to the technical field of foam guns, and relates to a spray head switching device of a foam device, which comprises a gun tube, a needle bar arranged in the gun tube, and a spray head arranged at the end part of the gun tube. The end part of the spray head is provided with a foam outlet port; the diameters of the gun tube and the spray head are larger than the outer diameter of the needle bar; and the needle bar can slide along the axial direction in the gun tube. The spray head switching device of a foam gun is characterized in that a smooth cambered-surface necked part and a conical hole part are sequentially arranged at the position from the inner hole of the spray head to the foam outlet port; and the head of the needle bar is provided with a conical sealing part used for opening or closing the foam outlet port on the spray head, and the conical sealing part is matched with the conical hole part on the spray head. The utility model has the advantages that the conical hole on the spray head and the inner hole of the spray head are treated by the necking treatment with the smooth cambered surface necked part, so that the needle rod slides smoothly, and the structures of a sealing ring, a plunger plug and the like are not used; and the situation of influence on the normal use of the foaming gun due to the damage of a sealing ring, a plunger and the like can be avoided. The utility model has simple structure, good sealing and long service life, and is suitably popularized in and applied to various types of foaming guns.
Description
Technical field
The utility model belongs to the foam gun technical field, refers in particular to a kind of nozzle switch device of foam gun.
Background technology
At present; in construction; in the house decoration; often need to use expanded material; expanding foam solution is sprayed in the slit behind the foamed solidification; can stop up the slit between the material; expanding foam solution generally is canned; spray in the slit by foam gun; the structure of existing foam gun includes handle; trigger; gun barrel; deck; gun barrel; shank; shank and trigger link; the leading section of gun barrel is provided with the shower nozzle of band bubble output hole; deck is used for the receiver that expanding foam solution is stored in clamping; pull trigger; described shank will endwisely slip in gun barrel; the bubble output hole on the shower nozzle can be opened in shank its end when sliding; the expanding foam solution that flows out in the set catheter on the deck can spray from the bubble output hole on the shower nozzle; in shower nozzle, be provided with a pressure cap; between pressure cap and shower nozzle, be provided with the sealing ring of a ring-type; it between pressure cap and the shower nozzle tight fit; its end meeting roof pressure is to sealing ring during shank work; thereby the switching of bubble output hole on the realization shower nozzle; this foam gun is when assembling; earlier sealing ring is put into shower nozzle; again pressure cap is pressed in the shower nozzle; the meeting roof pressure was on sealing ring after pressure cap was forced into the position; then shower nozzle is connected on the gun barrel; its weak point is: the one, and foam gun is in the use of reality; the phenomenon that shank can not be blocked the bubble output hole on the shower nozzle well takes place through regular meeting; this is because shank generally is to be made by metal material; with respect to softer sealing ring; the hardness of shank is higher; shank can often clash into sealing ring in the course of the work; make the sealing ring breakage easily like this; the 2nd, sealing ring is often soaked by expanding foam solution; time one is long; will make the sealing ring dilatancy, the sealing ring after the dilatancy gets lodged in the bubble output hole place on the shower nozzle, makes normally hydrojet or can not hydrojet of shower nozzle; cause device damage, increase economic loss.
Summary of the invention
The purpose of this utility model provides a kind of nozzle switch device of foam gun.
The purpose of this utility model is achieved in that the nozzle switch device of foam gun, comprise gun barrel, be located at shank in the gun barrel, be located at the shower nozzle of gun barrel end, the end of shower nozzle is provided with bubble output hole, the internal diameter of the endoporus of gun barrel and shower nozzle is greater than the external diameter of shank, shank can endwisely slip along it in gun barrel, it is characterized in that: to being disposed with slick and sly cambered surface necking part and tapered hole part between the bubble output hole, being provided with to match at the head of shank and being used to open or close the cone seal portion of the bubble output hole on the shower nozzle with tapered hole part on the shower nozzle at the endoporus of shower nozzle.
Above-mentioned shank is made with metal material.
Above-mentioned shank is made with copper product.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model directly cooperates the bubble output hole that is used to open or close on the shower nozzle with shank with shower nozzle, simple in structure, good sealing effect, carrying out necking down with slick and sly cambered surface necking part between the endoporus of bellmouth on the shower nozzle and shower nozzle handles, make that the cone seal portion of shank is smooth and easy when the tapered hole part of shower nozzle is slided, make good seal when closing, long service life;
2, the utility model is without sealing ring, plunger etc., and the situation of having avoided damaging the normal use that influences foam gun owing to sealing ring, plunger etc. takes place;
3, the utility model suits to apply on various types of foam guns.
Description of drawings
Fig. 1 be the utility model after moving trigger, make shank leave shower nozzle to open the partial sectional view behind the bubble output hole on the shower nozzle;
Fig. 2 is of the present utility model after unclamping trigger, and shank is withstood on the shower nozzle to close the partial sectional view behind the bubble output hole on the shower nozzle;
Fig. 3 is the partial sectional view after the utility model is installed on the foam gun.
The specific embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1-3:
The nozzle switch device of foam gun, comprise gun barrel 30, be located at the shank 20 in the gun barrel 30, be located at the shower nozzle 10 of gun barrel 30 ends, the end of shower nozzle 10 is provided with bubble output hole 102, the endoporus 301 of gun barrel 30 and shower nozzle 10,101 internal diameter is greater than the external diameter of shank 20, shank 20 can endwisely slip along it in gun barrel 30, it is characterized in that: to being disposed with slick and sly cambered surface necking part 194 and tapered hole part 103 between the bubble output hole 102, being provided with to match at the head of shank 20 and being used to open or close the cone seal portion 201 of the bubble output hole 102 on the shower nozzle 10 with tapered hole part 103 on the shower nozzle 10 at the endoporus 101 of shower nozzle 10.
