[0013] Beneficial effects:

[0014] This utility model provides a bolt with oil lubrication function. By pulling the round block upward, the round rod drives the extrusion block to squeeze the sponge block, so that the lubricating oil inside the sponge block flows through the oil outlet hole to the thread on the outer wall of the threaded rod.

The bolt with oil lubrication function includes: a bolt member 1, the bolt member 1 having a groove 2, the bolt member 1 being connected to an oil outlet assembly 4, the oil outlet assembly 4 being connected to an oil injection assembly 3, and a reset assembly 5 connecting the oil outlet assembly 4 and the bolt member 1. The oil outlet assembly 4 is used to deliver lubricating oil to the outside of the bolt member 1, the oil injection assembly 3 is used to inject lubricating oil into the oil outlet assembly 4, and the reset assembly 5 is used to control the movement of the oil outlet assembly 4.

[0023] The bolt component 1 includes a hexagonal block 11 and a threaded rod 12. The top of the threaded rod 12 is fixedly connected to the bottom of the hexagonal block 11. The groove 2 is opened on the top of the hexagonal block 11. A circular cavity 13 is opened inside the upper end of the threaded rod 12. The interior of the circular cavity 13 is connected to the oil outlet component 4.

[0024] A rubber pad is provided at the bottom of the hexagonal block 11 to prevent wear after the bottom of the hexagonal block 11 comes into contact with the part to be fixed.

[0025] The oil outlet assembly 4 includes a round rod 42 that extends from the bottom of the groove 2 into the interior of the circular cavity 13 and is slidably connected to the threaded rod 12. A round block 43 is installed on the top of the round rod 42, and a squeezing block 41 is installed on the bottom of the round rod 42. A sponge block 45 is installed on the inner wall of the circular cavity 13. Several sets of oil outlet holes 44 are evenly opened on the inner wall of the circular cavity 13. Each set of oil outlet holes 44 penetrates the outer wall of the threaded rod 12. The outer wall of the threaded rod 12 is connected to the reset assembly 5, and the sponge block 45 is connected to the oil injection assembly 3.

[0026] Lubricating oil is supplied to the sponge block 45 through the oil injection component 3. The round block 43 is pulled upward so that its round rod 42 drives the extrusion block 41 to extrude the sponge block 45. The lubricating oil inside the sponge block 45 flows through the oil outlet 44 to the thread on the outer wall of the threaded rod 12.

[0030] The groove 2 is hexagonal, and the groove 2 can be used as a backup for rotating the hexagonal block 11.

[0031] The working principle of the bolt with oil lubrication function provided by this utility model is as follows: After the bolt 1 is connected to the part to be fixed, when it is necessary to lubricate the connection, the oil outlet component 4 can squeeze the lubricating oil to the connection between the bolt 1 and the part to be fixed. The reset component 5 can automatically stop the oil outlet component 4 from discharging oil, and the oil injection component 3 can replenish the oil outlet component 4.

[0032] Compared with related technologies, the bolt with oil lubrication function provided by this utility model has the following advantages:

[0033] Beneficial effects:

[0034] By pulling the round block 43 upward, its round rod 42 drives the extrusion block 41 to extrude the sponge block 45, so that the lubricating oil inside the sponge block 45 flows through the oil outlet 44 to the thread on the outer wall of the threaded rod 12. At the same time, no matter what state the threaded rod 12 is in, it does not affect the flow of lubricating oil out of the oil outlet 44.

[0035] After the round block 43 is released, the spring 51 will push the round rod 42 to move downward automatically through the disc 52, thereby causing the extrusion block 41 to leave the sponge block 45 and stop the oil discharge.
