Oil injection nozzle for multifunctional lubricating oil gun

Abstract

The invention discloses an oil injection nozzle for a multifunctional lubricating oil gun. The oil injection nozzle comprises a connecting flange, a seal ring, a snap spring, a connecting oil injection head and a dustproof cover. The connecting oil injection head is arranged on the connecting flange. The connecting oil injection head is arranged on the connecting flange in a sleeved mode, and the connecting oil injection head and the connecting flange are connected together in a rotatable mode through the snap spring. The seal ring is arranged between a first insertion pipe of the connecting oil injection head and the connecting flange. A second insertion pipe is arranged on the connecting oil injection head and inclines upwards in a gradient mode. The dustproof cover comprises a cover cap, a connecting belt and a sleeve ring. The cover cap is connected with the sleeve ring through the connecting belt. The sleeve ring is arranged on the connecting flange in a sleeved mode. The cover cap covers the second insertion pipe. Compared with the prior art, the oil injection nozzle has the advantages that the phenomenon that some dust or other sharp objects adhere to an oil injection opening and then abnormal abrasion is caused to machine parts can be avoided, oil injection can be convenient, and the phenomenon that the oil injection opening of the oil injection nozzle is blocked by other parts, oil injection can not be conducted, and then abnormal abrasion is caused to mechanical parts can be avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of a grease nozzle, in particular to the technical field of a grease nozzle for a multifunctional lubricating gun. 【Background technique】 [0002] In the prior art, the grease nozzle used for the lubricating oil gun is a straight line structure, and the through hole is straight through. However, during use, the lubricating oil injection port of mechanical equipment is generally arranged within the reach of people, and it is often very difficult to align the lubricating oil injection port of the lubricating oil gun with a linear structure, especially the space above the lubricating nozzle. When limited, the operation is time-consuming and labor-intensive. [0003] The Chinese utility model patent with the notification number CN202769236U discloses a grease nozzle for a lubricating gun, which includes a connecting flange and a grease nozzle located on the flange, and the inner hole of the flange connects to...

Problems solved by technology

However, the oil injection inlet of the oil injection nozzle is directly exposed to the outside world, so some dust or other relatively sharp substances are easy to adhere to the oil injection port. When the oil is filled next time, it is easy to enter the lubricating surface with the oil, resulting in machine failure. abnormal wear

[0004] Although the existing grease nozzles also have a straight-through structure and a curved structure, no matter the straight-through or curved structure is fixed, the position where the grease nozzle is installed is often caused by the movement of the parts, causing the oil nozzle of the grease nozzle to be blocked. Blocked by other parts, resulting in constant or even impossible refueling, which will easily lead to abnormal wear of mechanical parts
