In order to achieve the above object, the present invention provides the following solutions: the utility model provides a rifle is glued to high gas tightness point, the electric iron comprises an iron body, the separation and reunion handle, the thimble, stroke adjusting device and shower nozzle, the thimble includes thimble seat and thimble rod, the thimble sleeve is established at the rifle internally, stroke adjusting device sets up and is close to thimble seat one side on the rifle body, the shower nozzle setting is close to thimble rod one side on the rifle body, separation and reunion handle one end is installed at thimble rod and thimble seat junction, the shower nozzle includes casing and first sealed the pad, first sealed pad is installed on the casing, all be equipped with the first through-hole that is used for the colloid circulation in first sealed pad and the casing, first sealed pad is the plastics material.
Further, the first sealing gasket is made of polyamide.
Furthermore, a fixing ring is arranged in the gun body, and a thimble seat of the thimble is sleeved in the fixing ring.
Furthermore, a non-return device is arranged in the gun body.
Furthermore, non-return device includes that housing bolt and second are sealed fills up, and housing bolt and second are sealed all to be equipped with the second through-hole in the middle part of filling up.
Furthermore, the second sealing gasket is made of plastic.
The utility model discloses an useful part lies in:
1. the gas tightness cooperation of some glue guns is mainly realized by thimble and shower nozzle, the first sealed pad of plastics (polyamide) material has been set up on the shower nozzle, first sealed pad and the casing has set up the first through-hole that is used for the colloid circulation, the thimble cooperatees with this first through-hole promptly, because polyamide itself is under the condition that receives certain external force, certain plasticity has, consequently, when the thimble pushes up in first through-hole many times, both can carry out the self-align of suitability, finally realize both zero clearance cooperations, promote the gas tightness of some glue guns.
2. Adopt the tight fit to be connected between first sealed pad and the casing, consequently, may lead to both fit clearance grow of first through-hole and thimble after long-term the use, at this moment, can dismantle the change with first sealed pad, practice thrift the maintenance cost.

Fig. 1 is a schematic structural view of the high-airtightness dispensing gun of the present invention.
Fig. 2 is the schematic diagram of the explosion structure of the assembly of the thimble, the stroke adjusting device and the nozzle in the high-airtightness dispensing gun of the present invention.
Reference numerals: the gun comprises a gun body 1, a clutch handle 2, a stroke adjusting device 3, an ejector pin 4, an ejector pin base 41, an ejector pin rod 42, a spray head 5, a first sealing gasket 51, a shell 52, a first through hole 53, a glue injection port 6, a spring 7, a pressing bolt 81 and a second sealing gasket 82.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1-2 of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
The utility model provides a high gas tightness point gum machine, including the rifle body 1, separation and reunion handle 2, thimble 4, stroke adjusting device 3 and shower nozzle 5, thimble 4 includes thimble seat 41 and thimble rod 42, thimble 4 cover is established in the rifle body 1, stroke adjusting device 3 sets up and is close to thimble seat 41 one side on the rifle body 1, shower nozzle 5 sets up and is close to thimble rod 42 one side on the rifle body 1, 2 one end of separation and reunion handle is installed in thimble rod 42 and thimble seat 41 junction, shower nozzle 5 includes casing 52 and first sealed pad 51, first sealed pad 51 is installed on casing 52, all be equipped with first through-hole 53 that is used for the colloid circulation in first sealed pad 51 and the casing 52, first sealed pad 51 is the plastics material, especially the polyamide material.
The clutch handle 2 controls the front and back movement of the ejector pin 4, a groove is formed in one side, which is assembled with the ejector pin 4, of the clutch handle 2, the ejector pin rod 42 is sleeved in the groove, the diameter of the ejector pin base 41 is larger than that of the groove, therefore, the ejector pin base 41 is abutted against the groove, the stroke adjusting device 3 is arranged at the tail end of the ejector pin 4, the stroke adjusting device 3 comprises an adjusting bolt, a mounting seat and a spring 7, the mounting seat is arranged at the tail end of the gun body 1, the adjusting bolt and the spring 7 are sleeved in the mounting seat, the adjusting bolt finely adjusts and moves in the mounting seat through a threaded structure, the spring 7 is compressed or released through the front and back movement of the adjusting bolt, the operation stroke of the clutch handle 2 is shortened during compression, the operation stroke of the clutch handle 2 is increased during release, and during normal use. The stroke resetting device also has another function, after the dispensing gun is used for a long time, a gap is generated between the ejector pin 4 and the first through hole 53 in a matching manner, at the moment, the adjusting bolt can rotate relative to the gun body 1 through the stroke adjusting device 3, finally, the adjusting bolt is abutted against the ejector pin base 41 of the ejector pin 4, and the ejector pin rod 42 is forcibly extruded towards the inside of the first through hole 53, so that the ejector pin rod 42 and the first through hole 53 are self-positioned again, the close matching is realized, and the gap problem is solved.
Glue injection mouth 6 sets up on the rifle body 1, and glue injection mouth 6 is located between shower nozzle 5 and the clamp bolt 81, for avoiding the colloid to clamp bolt 81 one side seepage, has still set up the sealed pad 82 of second at clamp bolt 81's front end, and the sealed pad 82 of second adopts the polyamide material equally, and clamp bolt 81 is inwards screwed to the sealed pad 82 of extrusion second realizes sealedly to clamp bolt 81 one side to the colloid.
In order to further promote the gas tightness of the glue dispensing gun, the fit clearance between the thimble seat 41 and the gun body 1 is also improved, a metal fit base is additionally arranged at the fit position of the thimble seat 41 and the shaft hole of the gun body 1, the metal fit base can ensure better fit with the thimble seat 41 through finish turning, and the occurrence of the conditions of gas leakage, liquid leakage and the like caused by the poor fit precision of the shaft hole between the gun body 1 and the thimble 4 is further avoided.
It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
