Description

The bidirectional portable oil gun

The utility model relates to a kind of bidirectional portable oil gun of annotating lubricating oil filling.

Existing locomotive such as automobile, tractor be the dual modes that adopt when annotating lubricating oil filling to gear-box more, and a kind of is manual filling, and another kind is to use the filling of SH-10L type oil gun.Filling is to use various containers by hand, and as cup, funnel, oil body is big again in the casing side because the filler of gear-box is many, so filling bothers, work efficiency is low, waste is oily.Using the filling of SH-10L type oil gun, because its volume is big, is 220 * 290 * 455 millimeters, and weight is big, be 10.5kg, complex procedures, and volume read-out is difficult for grasping, and the metal bucket inner wrapping has been carried out in the lubricated oil packaging of existing locomotive, so operation is many when refueling, and inconvenience.

The purpose of this utility model is to provide a kind of volume little, in light weight, easy to use and can grasp the bidirectional portable oil gun of volume read-out.

The mode that the utility model is realized is that it is by a cycloid gear pump, oil inlet pipe and oil outlet tube constitute, described cycloid gear pump is that external rotor and the internal rotor by the pump housing and pump housing inner chamber constitutes, the internal tooth of external rotor is meshed with the external tooth of internal rotor, internal rotor is affixed by an internal rotor fixing pin and inner rotor shaft, one end of inner rotor shaft is set on the pump housing by lining B, the termination is provided with stifle, the other end is set on the pump cover by lining A, the termination is connecting handle by the handle set screw, pump cover is connected with the pump housing with a locating stud by a pump cover fastening screw trip bolt, be respectively equipped with a fuel inlet fitting and a delivery connection in the bottom of the pump housing one side, connecting then oil inlet pipe that is enclosed within outside the oil-feed filter screen of an oil-feed filter screen and cover on the fuel inlet fitting, cover is followed an oil outlet tube on the delivery connection, connecting the fuel-displaced of a crooked shape on another termination of oil outlet tube chews, fuel inlet fitting is communicated with pump housing inner chamber by the oil input channel in the pump housing, and delivery connection is communicated with pump housing inner chamber by the oil road in the pump housing.

Advantage of the present utility model is that its volume is little, in light weight, easy to use and can well grasp volume read-out.Its volume diameter has only 62 millimeters, highly be 91 millimeters, the wind turning radius is 100 millimeters, weight has only 1.7kg, fuel-displacedly chew certain oiling angle, so easy to use, the utility model can two-wayly use, so when oiling finishes, can with oily upside-down mounting unnecessary in pump chamber and oil duct, the oil pipe in oil drum, not only avoid waste but also can keep health.
