Abstract
A spraying device of a pressure feed type spray gun comprises a nozzle, a gun needle, a gun needle nut, and a compression spring. The inner bore of the nozzle is shaped like an inner cone; the gun needle is sleeved in the nozzle; the gun needle nut is mounted at the tail end of the gun needle; and the compression spring is mounted on the gun needle nut. The spraying device is characterized in that: a conical platform and a conical point are further included, wherein the conical point is mounted on the conical platform, and the conical platform and the conical point are matched with the inner bore of the nozzle to form seal. The utility model aims to provide the spraying device of the pressure feed type spray gun, which has a simple structure and good sealing performance.
Description
Technical field
The utility model relates to a kind of spray equipment, relates in particular to a kind of spray equipment of pressure sending type spray gun for paint.
Background technology
In the pressure sending type spray gun for paint,, all can be provided with spray equipment by the rifle body in order to control the switching of coating.The spray equipment of existing spray gun for paint comprises nozzle, rifle pin, rifle pin nut, spring; Rifle pin nut is fixed on the rifle pin by screw thread, and rifle pin nut afterbody is equipped with spring.
In the use, promote rifle pin nut and then drive the rifle needle shaft by spring to moving, thereby make the rifle pin move away nozzle inner pyramidal backward and open coating, when not promoting rifle pin nut, the rifle pin moves axially under the effect of spring in the other direction, rifle pin front end tapering is withstood on form sealing on the nozzle endoporus, thereby close coating.There are the following problems to adopt the spray equipment of this structure: because of nozzle, rifle pin front end tapering must contact with nozzle endoporus intersection and form sealing, and because of the nozzle endoporus is little, procedure was definitely coaxial before and after work in-process was difficult to guarantee, thereby cause not sealing, easily produce and leak.
The utility model content
The utility model aims to provide a kind of spray equipment of pressure sending type spray gun for paint of simple in structure, good seal performance.
The technical scheme that the utility model adopted is: a kind of spray equipment of pressure sending type spray gun for paint, comprise nozzle, rifle pin, rifle pin nut, compression spring, the nozzle endoporus is an inner conical, and the rifle needle guard is contained in the nozzle, rifle pin nut is installed in rifle pin rear end, on the rifle pin nut compression spring is installed; It is characterized in that also comprising frustum, awl point, frustum is installed on the rifle pin, and the awl point is installed on the frustum, and frustum, awl point match with the nozzle endoporus, form sealing.
The beneficial effects of the utility model are: rifle pin front end is processed into two taperings, and contacts with nozzle inner pyramidal face with the intersection of these two taperings and to produce sealing, and simple in structure, processing and manufacturing easily and good airproof performance, yield rate height.
Description of drawings
Accompanying drawing 1 is the structural representation of the spray equipment of a kind of pressure sending type spray gun for paint of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Embodiment of the present utility model as shown in drawings, a kind of spray equipment of pressure sending type spray gun for paint, comprise nozzle 1, rifle pin 2, rifle pin nut 3, compression spring 4, frustum 5, awl point 6, nozzle 1 endoporus is an inner conical, rifle pin 2 is sleeved in the nozzle, rifle pin 2 rear ends are equipped with rifle pin nut 3, and compression spring 4 is installed on the rifle pin nut 3; Frustum 5 is installed on the rifle pin 2, and awl point 6 is installed on the frustum 5, and the tapering intersection of frustum 5, awl point 6 matches with nozzle 1 endoporus, forms sealing.
In the use, move axially by promoting rifle pin nut 3 and then driving rifle pin 2, thereby make rifle pin 2 move away nozzle 1 inner cone backward and open coating, when not promoting rifle pin nut 3, rifle pin 2 moves axially under the effect of compression spring 4 in the other direction, makes rifle pin 2 front ends awl pinnacle form sealing on nozzle 1 endoporus.
