Abstract

The invention relates to a coupler, in particular to an oilproof hose coupler. At present, in the aspect of automobile element matching, technical products in the 70s and 80s of last century have such multiple problems as weak reliability, weak matchability, weak use strength, only emergency and incapability of achieving durability and reliability in the aspects of matching and maintenance. The oilproof hose coupler comprises a screw body, and a nut coating the screw body, wherein an external thread matched with the nut is arranged at one end of the screw body. The oilproof hose coupler is characterized in that the other end of the screw body is a circular arc with a smooth surface; and the outer diameter of the nut is equal to the biggest diameter end of the screw body. The oilproof hose coupler is machined by metal iron or copper, and has the advantages of better strength and toughness, convenience for automobile maintenance and better universality. The matching is easy in the automobile production and maintenance aspects; the large scale and the standardization can be achieved in the production and application aspects; and the oilproof hose coupler can be applied to other chemical equipment fields.

Description

technical field [0001] The invention relates to a joint, especially an oil-resistant hose joint. Background technique [0002] At present, in terms of matching of automotive components, it is still a technical product from the 1970s to 1980s. In terms of matching and maintenance, there are many problems, such as: poor reliability, poor matching, poor use strength, only emergency, not durable and Reliable performance. Contents of the invention [0003] The purpose of the present invention is to provide a drop fuse with a simple structure and convenient operation, which can realize rated load operation capacity without using special tools. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: an oil-resistant hose joint, including a screw body and a nut sleeved on it, one end of the screw body is provided with an external thread that matches the nut, and its special feature is that the screw body The other e...
