Abstract
A polyurethane foaming agent spray gun with a trigger capable of being quickly mounted and dismounted comprises a gun nozzle, a gun pipe, a gun body, an adaptor, a handle, and an ejector pin in the gun pipe. A hole is formed in the gun body, chemical agents with pressure enter the gun body from the hole through the adaptor, and the trigger is arranged on the gun body and can control the chemical agents entering the gun body to be sprayed out through the gun nozzle. The trigger is detachably connected with the gun body. The polyurethane foaming agent spray gun has the advantages that bosses on the two sides of the gun body are directly formed in the pressure casting or injection molding process, the next metal machining process is omitted, and metal machining cost is saved. The trigger is detachably connected with the gun body, the number of parts is reduced, the assembling time is saved, and assembling efficiency is improved.

Utility model content
In order to overcome the shortcoming that existing trigger cannot easy disassembly, the invention provides the fast polyurethane foam agent spray gun of dismounting of a kind of trigger.
Trigger is a polyurethane foam agent spray gun for dismounting fast, comprises rifle mouth, gun barrel, rifle body, adapter and handle, and the thimble in gun barrel; Rifle body is provided with a hole, have the chemicals of pressure to be entered in rifle body by this hole by adapter, rifle body is provided with to control and enters the trigger that the chemicals of rifle body is sprayed by rifle mouth, between rifle body and trigger, is provided with sealing device, rifle body rear end is provided with adjusting nut, and it has handle; It is characterized in that: trigger is connected with rifle body detached type.
Further, described trigger comprises body and be positioned at picking up the ears of bodies top both sides, and each picks up the ears to be provided with the cylindrical projections to projecting inward, and described rifle body both sides are respectively equipped with boss, the counterbore that boss offers breach and coordinates with projection; Trigger body is provided with the mounting hole that allows thimble to pass, the upper and lower displacement of this mounting hole limit trigger.
Further, boss is c-shaped, the counterbore on boss and projection matched in clearance, the C shape edge of boss form by projection lock in it from lock section.
Or described trigger comprises body and be positioned at picking up the ears of bodies top both sides, each picks up the ears to be provided with groove, and described rifle body both sides are respectively equipped with the projection with the groove fit of picking up the ears, projection insert in groove and with groove matched in clearance; Trigger body is provided with the mounting hole that allows thimble to pass, the upper and lower displacement of this mounting hole limit trigger.
Further, the groove on picking up the ears is provided with and allows projection to enter the breach in it, the wall of groove form by projection be locked in groove from lock section.
The utility model is when trigger assembles, first the mounting hole through trigger body by thimble, then upwards carries trigger, and projection is pushed in the counterbore of boss from breach, as upwards caused projection to be deviate from from indentation, there in top trigger without external force, projection is locked in boss.
The utility model has the advantage of:
1, the boss of rifle body both sides can direct forming when die casting or injection moulding, saves the metalworking operation in Liao Hou road, has saved metalworking cost.
2, trigger is connected with rifle body detached type, has not only reduced number of spare parts, has also saved installation time, improves efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of rifle body.
Fig. 3 is the schematic diagram of trigger.
The specific embodiment
In conjunction with Fig. 1-3, further illustrate the utility model:
Trigger is a polyurethane foam agent spray gun for dismounting fast, comprises rifle mouth 4, gun barrel 3, rifle body 2, adapter 5 and handle 9, and the thimble in gun barrel 37; Rifle body 2 is provided with a hole, there is the chemicals of pressure to be entered in rifle body 2 by this hole by adapter 5, rifle body 2 is provided with to control and enters the chemicals of rifle body 2 by the trigger 1 of rifle mouth 4 ejections, between rifle body 2 and trigger 1, be provided with sealing device 6, rifle body 2 rear ends are provided with adjusting nut 8, and it has handle 9; Trigger 1 is connected with rifle body 2 detached types.
What described trigger 1 comprised body 11 and was positioned at body 11 both sides, top picks up the ears 12, each picks up the ears 12 to be provided with to projecting inward cylindrical projections 1a, described rifle body 2 both sides are respectively equipped with boss 21, the counterbore 22 that boss 21 offers breach 23 and coordinates with projection 1a, counterbore 22 is cylindrical or round taper hole.Trigger 1 body 11 is provided with the mounting hole 1b that allows thimble 7 to pass, the upper and lower displacement of this mounting hole 1b limit trigger 1.On trigger 1, two distances of picking up the ears between 12 are greater than the thickness of rifle body 2, so that trigger 1 can pack rifle body 2 into.Trigger 1 and rifle body 2 are for alloy material is by die casting aftershaping, and trigger 1 also can be by injection mo(u)lding.Thimble 7 comprises the back segment inserting in rifle body 2 and the leading portion inserting in gun barrel 3, and the diameter of leading portion is less than back segment diameter, and back segment and trigger 1 are fixing, and leading portion passes from the mounting hole 1b of trigger 1.。
Boss 21 is c-shaped, counterbore on boss 21 22 and projection 1a matched in clearance, the C shape edge of boss 21 form by projection 1a lock in it from lock section.Breach 23 is positioned at the side top of boss 21, as shown in Figure 1, 2.
The utility model is when trigger 1 assembling, first thimble 7 is passed to the mounting hole 1b of trigger 1 body 11, then trigger 1 is upwards carried, projection 1a is pushed in the counterbore 22 of boss 21 from breach 23, as upwards caused projection 1a to deviate from from breach 23 in top trigger 1 without external force, projection 1a is locked in boss 21.In use, cocking 1, along the inner surface rotation of counterbore 22, and then makes thimble 7 produce axial displacements under External Force Acting to foaming agent spray gun, opens or closes rifle mouth 4, realizes the start-stop spraying and controls.
