Description

Lubricating oil injector

technical field

The utility model relates to an oil injection tool. It is especially suitable for oiling tools for mechanical equipment lubricating oil.

Background technique

Due to the limited space at the main reducer and gearbox of automobiles and construction machinery equipment, people have to drill in to fill them with oil when there is no trench. It needs to be poured slowly with a small funnel or a pot with a fine pointed mouth. This traditional oiling method is not only slow in oiling, but also a very inconvenient work.

Contents of the invention

The purpose of the utility model is to provide a lubricating oil injector that can smoothly, conveniently and quickly inject oil into the main reducer and the gearbox of the equipment.

The purpose of this utility model is achieved in this way: including oil inlet hose, oil outlet hose, and oil inlet check valve, oil outlet check valve, valve seat, cylinder barrel, piston, piston rod and oil filling joint; valve seat There is an oil inlet check valve inside, and there are two joints on the valve seat, one is the oil inlet joint, which is used to connect the oil inlet hose, and the other is the oil outlet joint, which is connected to the oil outlet hose, and the oil outlet joint is equipped with Oil outlet one-way valve; the piston is installed in the cylinder, and the outer circle of the piston is equipped with a sealing ring; the oil outlet hose is connected to the oil joint.

From the above, it can be seen that the working principle of the utility model is similar to that of an air pump, which can conveniently inject lubricating oil into the equipment, and has the advantages of high efficiency and convenient use.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The specific operation process of a lubricating oil injector for filling the main reducer of the equipment is as follows: Referring to the attached drawings, insert the oil filling joint 2 on the oil outlet hose 1 into the oil filling hole of the main reducer shell 3, and insert the oil inlet hose 4 Insert it into the oil container 5, step on the pedal 6 with your feet, pull up the handle 7, and the piston rod 8 drives the piston 9 to rise. At this time, the oil inlet check valve 12 is opened under the action of atmospheric pressure, and the oil outlet is one-way The valve 16 is closed under the action of the spring 18, so that the lubricating oil in the oil container 5 enters the cylinder 13 through the oil inlet hose 4, the oil inlet joint 10, the channel 17 in the valve seat 11, and the oil inlet check valve 12 Inner (inside the rodless cavity). When the piston 9 reaches the top, press down the handle 7, and the piston moves downward. At this time, the oil inlet check valve is closed, and the lubricating oil in the cylinder 13 pushes the oil outlet check valve in the oil outlet joint 15 through the channel 14 of the valve seat 11. 16 enters the oil outlet hose 1 and flows into the final reducer housing 3 through the oil injection joint 2. In this way, the handle is pulled up and down, and the lubricating oil will continuously flow from the oil container to the oil filling position.
