Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Shown in composition graphs 1, Fig. 2, Fig. 3, pressing injecting type Pneumatic grease gun, comprises pipe, rifle mouth 12 before and after the body of a gun 1, gun barrel piston, rifle.
The upper intersegmental part of the body of a gun 1 is provided with stop valve 4, and stop valve 4 is connected with trigger 3, and trigger 3 is located at the body of a gun 1 handle place, is flexibly connected between the tail end of trigger 3 and the body of a gun 1 by safety fastener 2.
The structure of gun barrel piston is normally closed piston valve, comprises cover 7, containment vessel 8, piston valve core 9, spring 13, piston protheca 10 after reducing sleeve 6, piston.
Spring 13 is socketed in piston valve core 9 outer ring, and after piston valve core 9 is embedded in piston, cover 7 is inner.The outer cover of overlapping 7 composition integrative-structures after spring 13, piston valve core 9, piston has containment vessel 8.Containment vessel 8 leading portion is flexibly connected with piston protheca 10, containment vessel 8 back segment with overlap 7 after piston and be flexibly connected, overlap 7 after piston and be flexibly connected with reducing sleeve 6 after containment vessel 8 tail end stretches out.
Before and after rifle, pipe comprises output tube 11 and connecting tube 5.Output tube 11 one end is fixedly communicated with rifle mouth 12, and the other end is fixedly communicated with the front end of piston protheca 10.One end of connecting tube 5 to be embedded in reducing sleeve 6 and with overlap 7 after piston and is communicated with, the other end is connected with the body of a gun 1 port and is communicated with the body of a gun 1 is inner.
As to further optimization of the present utility model, containment vessel 8 leading portion and back segment are equipped with screw thread, and respectively with overlap 7 after piston protheca 10, piston and be threaded, overlap 7 after piston and be threaded with reducing sleeve 6 after containment vessel 8 tail end stretches out.The diameter of the leading portion screw thread of containment vessel 8 is greater than the external diameter of cover 7 after piston, and the middle part of containment vessel 8 is smooth.As shown in Figure 4 and Figure 5, piston valve core 9 comprises valve core cap 91 and valve core head 92 two-part, and valve core cap 91 and valve core head 92 are threaded connection, and facilitate the assembling of gun barrel piston.The body of a gun 1 tail end is also communicated with oil pipe.
During the assembling of gun barrel piston, first form integrally overlap 7 after piston valve core 9 and spring 13 and piston, then loaded containment vessel 8, containment vessel 8 leading portion, back segment have screw thread and the leading portion diameter of thread overlap after being greater than piston 7 external diameter, middle part is smooth.Overlap 7 after the piston be connected with piston valve core 9 to load, after after piston, cover 7 stretches out from the tail end of containment vessel 8, with reducing sleeve 6 with being threaded.Finally load piston protheca 10 and be threaded with containment vessel 8 leading portion.
The utility model body of a gun 1 controls stop valve 4 by trigger 3, is designed with safety fastener 2 at handle place, its effect is locking trigger 3, makes stop valve 4 be in normally open.In use, can open when piston valve is subject to axially pressing, connect oil pipe, containment vessel 8 worm structure part can be adjusted when needed locked, make piston valve keep normally open.The open and-shut mode of two valves of adjustment piston valve and stop valve 4, can complete two kinds of work requirements.Be specially following two kinds of situations:
To when having a station oiling of oil nozzle, the state of adjustment Pneumatic grease gun is piston valve normally off, and locking trigger 3 makes stop valve 4 become normally open.Now the break-make of oil circuit is controlled by the circulation of piston valve and cut-off state.During oiling, rifle mouth 12 is aimed at oil nozzle, and make rifle mouth 12 press oil nozzle by operator, so while being compressed by rifle mouth 12, piston valve is started, connect rifle mouth 12 and oil pipe, complete oiling.
When to station oiling without oil nozzle, can piston valve core 9 pusher to special position by screw-threaded coupling, make piston valve become normally open.Untie trigger 3 snap close, make stop valve 4 for normally off.Now oil circuit break-make is controlled by trigger 3.Only need cocking 3 that stop valve 4 can be made to become circulation status and complete oiling.
The utility model passes through with the body of a gun 1 of stop valve 4 and the gun barrel piston of piston valve construction, reach the object of the wrist health problem avoiding traditional grease gun to operate bringing to workman, provide more easy oiling mode flexibly simultaneously, meet the demand of different operating.
