[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a car tie rod comprises a tie rod body 1, one end of the tie rod body 1 is fixedly connected to a ball head seat 2, the inner ring of the ball head seat 2 is clamped with a sealing cover 3, the sealing cover 3 is provided with an oil storage chamber 31, the interior of the oil storage chamber 31 is provided with an upper oil pipe 4 whose two ends respectively penetrate through both sides of the sealing cover 3, the upper oil pipe 4 is installed with an oil inlet assembly, an oil outlet assembly and a third flexible member 10, the third flexible member 10 is made of rubber, the sealing cover 3 is installed with an extrusion assembly, the upper oil pipe 4 is provided with a first through hole 41, a second through hole 42 and a third through hole 43, the oil outlet assembly The lubricating oil is arranged in the first through hole 41, and the lubricating oil can be sprayed from the oil outlet assembly to the ball head installed on the ball head seat 2, but the lubricating oil cannot enter the interior of the upper oil pipe 4 from the oil outlet assembly. The oil inlet assembly is arranged in the second through hole 42, and the lubricating oil can enter the interior of the upper oil pipe 4 from the oil inlet assembly, but the lubricating oil located inside the upper oil pipe 4 cannot go out therefrom. The third flexible member 10 is arranged in the third through hole 43, and the extrusion assembly sucks the lubricating oil from the oil inlet assembly into the interior of the upper oil pipe 4 by extruding the third flexible member 10, and finally sprays it out from the oil outlet assembly.

[0025] Specifically, by rotating the upper oil pipe 4 to continuously squeeze the third flexible member 10 through the extrusion assembly, the lubricating oil located inside the oil storage chamber 31 can enter the interior of the upper oil pipe 4 from the oil inlet assembly, and finally be sprayed toward the ball head by the oil outlet assembly, so as to facilitate the lubrication of the ball head, reduce the wear between the ball head and the ball head seat 2, and increase the service life.

[0026] like Figure 3 As shown, the extrusion assembly includes an extrusion block 11, which is movably sleeved in the groove of the sealing cover 3. The round end of the extrusion block 11 is in contact with the third flexible member 10, and the other end is fixedly connected with an elastic member 12. The elastic member 12 adopts a spring and is used to push the extrusion block 11 to approach the upper oil pipe 4. The end of the elastic member 12 away from the extrusion block 11 is fixedly connected to the groove of the sealing cover 3.

[0027] Specifically, when the upper oil pipe 4 is rotated, the third through hole 43 will squeeze the extrusion block 11 out of the third through hole 43, and the bent third flexible member 10 will return to a flat state. When the third through hole 43 is realigned with the extrusion block 11, the elastic member 12 will push the extrusion block 11 to squeeze the flat third flexible member 10 into a bent state, thereby changing the pressure inside the upper oil pipe 4.

[0028] like Figure 3 As shown, the oil inlet assembly includes a second flexible member 8 and a second filter screen 9. The second flexible member 8 is fixedly installed in the oil inlet of the upper oil pipe 4, and the second flexible member 8 is located on the side of the oil inlet close to the interior of the upper oil pipe 4. The second filter screen 9 is fixedly installed in the oil inlet of the upper oil pipe 4, and the second filter screen 9 is located on the side of the oil inlet close to the oil storage chamber 31, which is used to prevent the cross-shaped knife formed on the second flexible member 8 from deviating toward the second filter screen 9.

[0029] Specifically, when the third flexible member 10 is deformed to change the pressure inside the upper oil pipe 4, the lubricating oil in the oil storage chamber 31 will enter from the second filter screen 9, push open the cross cutter formed on the second flexible member 8, and finally enter the interior of the upper oil pipe 4. Since the second filter screen 9 is against one side of the second flexible member 8, the lubricating oil in the upper oil pipe 4 cannot pass through it, thereby preventing the lubricating oil from re-entering the interior of the oil storage chamber 31.

[0030] like Figure 3 As shown, the oil outlet assembly includes a first flexible member 6 and a first filter screen 7. The first flexible member 6 is made of rubber and has a cross pattern cut to facilitate the passage of lubricating oil therethrough. The first flexible member 6 is fixedly installed in the oil outlet of the upper oil pipe 4. The first flexible member 6 is located on a side of the oil outlet close to the outside of the sealing cover 3. The first filter screen 7 is fixedly installed in the oil outlet of the upper oil pipe 4. The first filter screen 7 is located on a side of the oil outlet close to the inside of the upper oil pipe 4, and is used to prevent the cross pattern cuts formed on the second flexible member 8 from deviating toward the second filter screen 9.

[0031] Specifically, when the third flexible member 10 is deformed to change the pressure inside the upper oil pipe 4, the lubricating oil inside the upper oil pipe 4 will flow out from the first filter screen 7, and push open the cross cutter formed on the first flexible member 6, and finally spray onto the ball head mounted on the ball head seat 2. Since the first filter screen 7 is against one side of the first flexible member 6, the lubricating oil attached to the ball head cannot pass through it, thereby preventing the lubricating oil from re-entering the interior of the upper oil pipe 4.

[0032] like Figure 3 As shown, a knob 5 is fixedly connected to the outer wall of the upper oil pipe 4 , and the upper oil pipe 4 is driven to rotate by rotating the knob 5 , thereby facilitating lubrication of the ball head installed on the ball head seat 2 .

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
