Detailed ways

The present utility model will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

As shown in FIG. 1 , a portable oil injector for a reducer provided according to the present invention includes an oil injection bottle 1 , an oil injection pipe 5 , a ball valve 3 and a bottle cap 2 . The oil filling bottle 1 is translucent or fully transparent, and a volume scale is etched on the side wall of the oil filling bottle 1. The staff can see the upper liquid level of the oil in the oil filling bottle 1 through the oil filling bottle 1. The volume scale on the top can make the staff accurately see the change of the oil quantity in the oil filling bottle 1, so as to realize the quantitative oil filling of the reducer.

Specifically, the oil filling bottle 1 includes a fully transparent or translucent glass bottle, and a fully transparent or translucent plastic bottle. This application preferably uses a translucent plastic bottle, which is light in weight and easy to carry.

The bottom of the oil filling bottle 1 is integrally formed with an oil outlet, and the oil outlet is an inner screw port. The ball valve 3 is a stainless steel miniature ball valve, which has a certain anti-rust performance. The ball valve 3 can be detachably installed at the oil outlet, and the ball valve 3 can control the opening or closing of the oil outlet. The upper end of the ball valve 3 is provided with an outer screw port, and the outer screw port of the upper end of the ball valve 3 is threadedly matched with the inner screw hole of the oil outlet, so that the detachable connection between the ball valve 3 and the oil outlet is realized. The lower end of the ball valve 3 is provided with an outer screw opening, and the outer screw opening at the lower end of the ball valve 3 is used for detachable connection with the quick connector 4 , and the valve of the ball valve 3 is located in the middle of the ball valve 3 .

One end of the oil injection pipe 5 is provided with an external screw port, and the oil injection pipe 5 is connected with the ball valve 3 through the quick joint 4, thereby realizing the detachable connection between the oil injection pipe 5 and the oil outlet. The inventor believes that the oil outlet, the ball valve 3, the quick connector 4 and the oil filling pipe 5 are all connected by a detachable live port, which is convenient for replacing parts of different sizes, and has stronger adaptability.

The bottle cap 2 can open or close the top of the oil filling bottle 1. The top of the oil filling bottle 1 includes an inner screw opening, and the lower end of the bottle cap 2 is provided with an outer screw opening. The thread fit of the outer screw port realizes the detachable installation of the bottle cap 2 on the top of the oil filling bottle 1 . When the oil filling bottle 1 needs to be refueled, the bottle cap 2 can be opened for refueling; when the oil filling is completed, the bottle cap 2 can be screwed in place. The oil overflows from the connection between the bottle cap 2 and the oil filling bottle 1, and can ensure that the interior of the oil filling bottle 1 is a closed space.

The bottle cap 2 is provided with a pressurizing port, a throttle valve 7 is installed on the thread of the pressurizing port, and the throttle valve 7 is connected with an air pipe through a thread, and the air pipe can be communicated with an external air source, so as to realize the inflation of the inner space of the oil filling bottle 1.

Under normal conditions, by placing the oil filling bottle 1 at a position higher than the oil filling port of the reducer oil tank and opening the ball valve 3, the oil in the oil filling bottle 1 can flow into the oil tank of the reducer through the oil filling pipe 5. Quantitative refueling can be realized by changing the liquid level in 1. However, due to the viscosity of the oil itself, when the cross section of the oil injection pipe 5 is small, and the height difference between the oil injection bottle 1 and the oil filling port of the reducer oil tank is not large, there is a problem that the oil cannot flow into the reducer oil tank smoothly, and the staff is very concerned about the oil injection. Speed is difficult to control.

Therefore, the pressure port on the bottle cap 2 is connected to the air source, for example, the air compressor pipeline can be connected to the factory building, and the oil filling bottle 1 can be inflated through the external air source, thereby increasing the internal air pressure of the oil filling bottle 1, opening the ball valve 3, and the oil Under the action of the internal pressure of the oil filling bottle 1, it flows into the oil tank of the reducer through the oil filling pipe 5, which can ensure the oil filling of the reducer oil tank under the condition that the oil viscosity is high and the cross-sectional area of the oil filling pipe 5 is small. By adding an external air source, there is no requirement for the height difference between the oil filling bottle 1 and the oil filling port of the reducer oil tank, so the convenience of placing the oil filling bottle 1 can be improved, and the applicability of the portable oil filling device can also be improved.

Further, the throttle valve 7 installed at the pressure port can block the air source to inflate and pressurize the oil bottle 1 at any time, and the throttle valve 7 can also adjust the speed of the external air source to inflate and pressurize the oil bottle 1. , and then can realize the control of the oil injection speed.

Further, a pressure relief valve 6 is installed on the bottle cap 2. When the threshold value of the pressure relief valve 6 meets the oil outlet opening, the oil in the oil filling bottle 1 can pass through the oil filling pipe 5, and the air pressure in the oil filling bottle 1 does not damage the oil filling. bottle 1, so as to ensure the safety and service life of the oiler.

In order to further improve the convenience of using the oil injector, a portable handle is installed on the outer side wall of the oil filling bottle 1. On the one hand, it is convenient for the staff to move the oil filling bottle 1. On the other hand, for the extreme working environment, the staff can hold the oil filling bottle 1. Fill the reducer oil tank with oil. Further, the bottom of the oil filling bottle 1 gradually shrinks from top to bottom, and the oil outlet is located at the shrinking center of the bottom of the oil filling bottle 1. With the bottom of the oil filling bottle 1 gradually shrinking downward, on the one hand, it is convenient for the oil in the oil filling bottle 1 to pass through the outlet. The oil port flows into the oil filling pipe 5, on the other hand, it is convenient to place the oil filling bottle 1 on the hollow mechanical frame body.

Preferably, the oil filling pipe 5 adopts a hose, which can improve the applicability of the oil filling device.
