DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] like Figures 1 to 4 As shown, a high-sealing self-lubricating ball joint bearing includes a ball pin seat 1 and a ball pin. An oil filling hole is opened on the top of the ball pin seat 1, and an oil filling valve 2 is arranged in the oil filling hole. The oil filling hole is connected with an oil storage channel 3, and the oil storage channel 3 is located inside the ball pin seat 1. A pressure groove is also arranged inside the ball pin seat 1, and the pressure groove is communicated with the top of the oil storage channel 3. A pressure mechanism is arranged in the pressure groove. The bottom of the oil storage channel 3 is connected with an oil blocking channel, and an oil baffle plate 4 is arranged in the oil blocking channel. A first oil inlet hole 5 and a second oil inlet hole 6 are arranged on the surface of the oil baffle plate 4, and a first oil outlet hole 7 and a second oil outlet hole 8 are arranged on one side of the oil baffle plate 4. The first oil inlet hole 5 is connected to the first oil outlet hole 7, and the second oil inlet hole 6 and the second oil outlet hole 8 are connected. A driving mechanism for driving the oil baffle plate 4 to move is arranged on one side of the oil baffle plate 4.

[0028] When in use, first inject the lubricating oil into the oil filling valve 2, the oil filling hole and the oil storage channel 3 are connected, the lubricating oil enters the oil storage channel 3, and through the action of the pressurizing mechanism, the lubricating oil contacts the oil baffle plate 4, and the driving mechanism pulls the oil baffle plate 4 to move until the oil inlet hole on the oil baffle plate 4 contacts the lubricating oil. Under low temperature conditions, the overall demand for lubricating oil in the bearing is relatively small, and the driving mechanism is used to pull the oil baffle plate 4 to the specified position so that the first oil inlet hole 5 and the lubricating oil contact, and the pressurizing mechanism applies a small pressure to the oil storage channel 3, and the lubricating oil is discharged through the first oil outlet hole 7 to achieve the effect of lubricating the ball pin. Under high temperature conditions, the overall demand for lubricating oil in the bearing is relatively large, and the driving mechanism is used to pull the oil baffle plate 4 to the specified position so that the first oil inlet hole 5 and the lubricating oil contact, and the pressurizing mechanism applies a large pressure to the oil storage channel 3 so that the second oil inlet hole 6 and the lubricating oil contact, and the lubricating oil is discharged through the second oil outlet hole 8, which not only lubricates the ball pin, but also does not cause waste of lubricating oil.

[0029] The ball pin is arranged in the ball pin seat 1, and the design between the ball pin seat 1 and the ball pin allows the supply of lubricating oil through the oil storage channel 3 and the oil blocking channel; the lubricating oil can be injected through the oil filling hole, pass through the oil storage channel 3 to reach the inside of the ball pin seat 1, and provide lubrication for the friction between the ball pin and the ball pin seat 1; an oil filling valve 2 is arranged in the oil filling hole to ensure that there will be no leakage of lubricating oil when not in use.

[0030] A spherical cavity is formed inside the ball pin seat 1. The ball pin comprises a ball head 9 and a ball rod 10. The ball head 9 is placed in the spherical cavity.

[0031] The design of the spherical cavity allows the ball head 9 to rotate freely therein, reducing the friction and wear caused by the fixed connection; lubricating oil can enter the spherical cavity through appropriate channels to provide lubrication for the friction between the ball head 9 and the spherical cavity, further reducing friction and wear.

[0032] The pressurizing mechanism comprises a cylinder 11 , in which a pumping rod 12 is arranged, a handle 13 is arranged on the surface of the pumping rod 12 , an air outlet pipe 14 is arranged at the bottom of the cylinder 11 , and two positioning seats 15 are arranged on the circumferential surface of the cylinder 11 .

[0033] The cylinder 11 contains components such as a piston and a piston rod (not shown in the figure). The setting of the handle 13 allows the user to easily hold and operate the air pump 12, and the pressure applied to the oil storage channel 3 can be changed by the fast and slow movement of the air pump 12; the setting of the positioning seat 15 enhances the stability of the cylinder 11 and prevents it from shaking or tilting during operation; the movement of the air pump 12 in the cylinder 11 can generate pressure and output high-pressure gas through the outlet pipe 14.

[0034] A connecting rod 16 is disposed between the two positioning seats 15 ; the connecting rod 16 serves as a part of the structural support, firmly connecting the two positioning seats 15 together, thereby enhancing the stability of the entire pressurizing mechanism.

[0035] The driving mechanism comprises a spring rod 17 fixedly connected to the oil baffle 4 , a push-pull block 18 is fixedly connected to one side of the spring rod 17 , and a limiting mechanism for limiting the push-pull block 18 is provided on one side of the push-pull block 18 .

[0036] The displacement of the push-pull block 18 can drive the spring rod 17 and the oil baffle plate 4 to move. The displacement of the oil baffle plate 4 can adapt to a variety of situations. Depending on the situation, the first oil inlet hole 5 or the second oil inlet hole 6 is brought into contact with the lubricating oil. After the push-pull block 18 is slid to the specified position, the push-pull block 18 is limited by the limiting mechanism so that the push-pull block 18 will not shake or shift during use.

[0037] The limiting mechanism includes two limiting bases 19 arranged on both sides of the push-pull block 18. The two limiting bases 19 are fixedly connected to the circumferential surface of the ball pin seat 1. A plurality of limiting holes 20 are opened on one side of the two limiting bases 19. A limiting rod 21 is arranged in the limiting hole 20. The limiting rod 21 passes through the push-pull block 18. There are two limiting holes 20.

[0038] When the push-pull block 18 is pulled to the desired position, the limit rod 21 is used to limit the push-pull block 18, so that the operator does not need to hold the push-pull block 18 all the time to keep the oil baffle plate 4 in the specified position, and the ball pin can be lubricated smoothly, and the position of the push-pull block 18 can be accurately controlled; and the stability of the structure can be enhanced. The limit base 19 is fixedly connected to the circumferential surface of the ball pin seat 1, providing a stable support for the limit mechanism; the limit hole 20 allows the position of the limit rod 21 to be adjusted as needed. In this solution, the number of oil inlet holes set on the oil baffle plate 4 is two, so the number of corresponding limit holes 20 is also two.

[0039] A sealing groove is provided at the bottom of the ball pin, and a sealing ring 22 is arranged in the sealing groove. The diameter of the sealing ring 22 is slightly larger than the sealing groove. The sealing ring 22 abuts against the ball pin. A fixing ring 23 is provided on the surface of the sealing ring 22. A limiting bolt is provided on the surface of the fixing ring 23. The limiting bolt passes through and is threadedly connected to the sealing ring 22 and the ball pin seat 1.

[0040] The sealing ring 22 reduces the outflow of lubricating oil in the spherical cavity. The sealing ring 22 is an elastic element and abuts against the ball pin. After the ball head 9 is installed in the spherical cavity, the free rotation of the ball head 9 will not leak the lubricating oil in the spherical cavity. The diameter of the sealing ring 22 is slightly larger than the sealing groove, thereby effectively preventing dust, moisture or other impurities from entering the interior of the ball pin seat 1 and reducing the lubrication effect. The setting of the fixing ring 23 enables the sealing ring 22 to be firmly fixed in the sealing groove to prevent it from shifting or falling off during use.

[0041] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
