[0022] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0023] A nut for oil pipelines, see Figures 1 to 4 , comprising a petroleum pipeline nut body 1, a group of auxiliary components 2 are provided on the surface of the petroleum pipeline nut body 1;

[0024] The oil pipeline nut body 1 includes a nut body 101, with a washer 102 attached to one side of the nut body 101. The threads on the inner side of the nut body 101 are opposite to the threads on the inner side of the washer 102. A plurality of locking teeth 103 are evenly distributed on the surface of the washer 102 on the side away from the nut body 101. An annular slide rail 104 is provided on the surface of the washer 102 on the side close to the nut body 101. Furthermore, the washer 102 and the locking teeth 103 are fixedly connected and are integrally formed with the annular slide rail 104. The utility model can effectively assemble the nut body 101 and the washer 102 through the auxiliary component 2. After assembly, the nut body 101 and the washer 102 restrain each other on the bolt surface, offsetting the rotational force, reducing the possibility of loosening of the oil pipeline nut body 1. The locking teeth 103 on one side of the washer 102 can effectively bite and lock the outer end face of the oil pipeline, improving the tightness of the connection.

[0025] It is worth noting that the auxiliary component 2 includes a positioning plate 201, a screw 202 is inserted into the interior of the positioning plate 201, a handle 203 is fixed to the end of the screw 202, and a positioning groove 204 is provided on the surface of the nut body 101, wherein the positioning plate 201 forms a threaded structure through the screw 202 and the positioning groove 204, and the positioning groove 204 and the nut body 101 are integrally formed, and a T-shaped slide bar 205 is fixed to the surface of the positioning plate 201, further, the T-shaped slide bar 205 is engaged with the inside of the annular slide rail 104, and the positioning plate 201 forms a rotating structure with the annular slide rail 104 through the T-shaped slide bar 205. In the present invention, the washer 102 is rotated to be sleeved on the surface of the oil pipeline connecting bolt, and then the nut body 101 is rotated so that the nut body 101 is tightly against the washer 102 on the basis of being sleeved on the surface of the oil pipeline connecting bolt. Then, a group of positioning plates 201 are rotated along the annular slide rail 104 to the side where a group of positioning grooves 204 are located, and the positioning plates 201 are fixed to the side where the positioning grooves 204 are located by the screw rod 202, completing the assembly between the nut body 101 and the washer 102.

[0026] Working principle: Rotate the gasket 102 so that it is first sleeved on the surface of the oil pipeline connecting bolt, and then rotate the nut body 101 so that the nut body 101 is close to the gasket 102 on the basis of its sleeve on the surface of the oil pipeline connecting bolt, and then rotate a group of positioning plates 201 along the annular slide rail 104 to the side where a group of positioning grooves 204 are located, and fix the positioning plates 201 to the side where the positioning grooves 204 are located through the screw 202 to complete the assembly between the nut body 101 and the gasket 102. After the assembly is completed, the nut body 101 and the gasket 102 restrain each other on the bolt surface, offset each other's rotational force, and reduce the possibility of loosening of the oil pipeline nut body 1. The locking teeth 103 on one side of the gasket 102 can bite and lock the outer end face of the oil pipeline to improve the tightness of the connection.
