2. Description of the Prior Art
Please refer to
When the new oil is infused too much so that the oil level is over the top end of the oil-importing tube, there are two ways to drain extra oil. The first way is as described in the first paragraph, and the second way is to use an oil-importing tube capable of adjusting extending length. After adjusting the oil-importing tube to a suitable length, the extra oil can be drained out from the oil-importing tube.
However, both two ways described above have complex steps to change the oil. And an extra container is needed for containing the oil drained. Although the oil left can be reused, the new oil drained may be polluted or oxidized.
On the other hand, according to the first way described in the first paragraph, the oil is easy to sprinkle on the ground or users because of a fast sprinkling speed. By the second way, a refueling device has to be removed to drain the oil. But the new oil would leak out from the oil-importing tube to the ground in the process of removing the refueling device, causing an unnecessarily waste. Users have to spend extra effort s for cleaning the oil stains; or the environment would be polluted. Furthermore, passengers would slip and fall or a fire would be occurred easily.
SUMMARY OF THE INVENTIONThe main object of the present invention is to provide an oil changing device of a gear box, and more especially to an oil changing device capable of being used to infuse and drain oil directly.
To achieve the above, the present invention provides an oil changing device including comprising a bucket and an adjusting structure. The adjusting structure is disposed between the bucket and a gear box.
The adjusting structure comprises a refueling device, an adjusting valve assembly, and an oil-exporting tube. The adjusting valve assembly comprises an oil-importing valve and an oil-exporting switch. The refueling device is used for pressuring gear box oil stored in the containing room of the bucket passing the oil-importing vale and going into the gear box, and the oil-exporting switch drives the gear box oil passing the oil-exporting tube and going out of the adjusting structure.
As such, the oil changing device of the present invention can infuse the new oil into the gear box and drain the extra oil out from the gear box.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
Please refer to
The bucket has a bucket opening and a containing room. The containing room connects to the bucket opening. The bucket comprises a lid 11 closed on the bucket opening, and the containing room is used for storing oil of the gear box. The oil of the gear box can be new oil as well.
One end of the adjusting structure is disposed on the bucket, and another end of the adjusting structure can be used for connecting with the gear box. The adjusting structure connects the containing room to the gear box so that oil ducts are adjusted by the adjusting structure. The adjusting structure comprises a refueling device 21, an adjusting valve assembly, an oil-exporting tube 23, an oil-importing tube 24, and an oil-exporting tube 25. The refueling device is disposed on the bucket, and the adjusting valve assembly comprises an oil-importing valve 221, an oil-exporting valve 222, an oil-exporting switch 223 and T-valve. The T-valve comprises a first tube 224 and a second tube 225. The first tube 224 has a first opening 227 and a second opening 226 at both ends respectively. The second tube 225, having an opening 228 on one end away from the first tube 224, horizontally extends from a lateral side of the first tube 224. The oil-importing valve 221 is disposed with the first tube 224. The oil-importing valve 221 is close to the second opening 226 of the first tube 224. The oil-importing tube 24 connects the bucket 1 to the second opening 226 of the first tube 224 so that the oil-importing tube 24 connects the oil-importing valve 221 to the containing room. The oil-exporting switch is disposed with the first tube with being close to the first opening 227 of the first tube. The oil-exporting valve 222 is disposed between the first opening 227 of the first tube and the oil-exporting switch. The bucket 1 is disposed with an inserting portion 12, and the inserting portion 12 has a hole 121 connecting to the containing room. One end of the oil-exporting tube 25 connects to the first opening 227 of the first tube, and another end of the oil-exporting tube 25 is engaged with the inserting portion. One end of the connecting tube 23 connects to the opening 228 of the second tube 225, and another end of the connecting tube 23 can be used for connecting to the gear box. To increase more perfection to the oil changing device of the present invention, the connecting tube 23 comprises a switch device 231 used for the connecting tube 23 so that the connecting tube 23 connects the adjusting valve to the gear box selectively. As such, the switch of the connecting tube 23 and the oil-exporting switch 223 can be closed before changing oil so that the new oil would not be oxidized or polluted.
Users can drain the oil in the gear box out before changing the oil. Please refer to

More importantly, the oil-importing valve 221 and the oil-exporting vale 222 are unidirectional. That is, the new oil would not flow back to the bucket 1 after passing the oil-importing valve 221 in the process of infusing the new oil. Also, the extra oil would not flow back to the bucket 1 via the oil-importing valve 221 in the process of draining the oil. As such, the oil changing device of the present invention can keep a certain efficiency of infusing and draining the oil.
