Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories equipment, more specifically to an automobile ball pin seat with good sealing performance. Background Art
[0002] The cooperation between the ball pin and the ball pin seat is a commonly used connecting component in the mechanical field. It is widely used in people's lives. In the automobile manufacturing industry, the ball pin seat plays an indispensable role. In actual use, if the sealing of the ball pin seat is not good, it is easy to cause the connection to loosen. The loosened ball pin seat will produce a large vibration as a whole, resulting in poor stability of the connecting component, causing large losses and poor use effect. If the torque produces a large fluctuation, it will link the connecting part at its upper end to shake, and the buffering is poor. In addition, the existing ball pin seat is usually provided with a dust cover for dust prevention, but many dust covers have poor sealing and mud and sand enter. At the same time, the dust cover is prone to rupture or poor sealing during driving, which reduces the quality pass rate and increases the after-sales cost. In view of this, the inventor proposes a car ball pin seat with good sealing performance. By arranging a buffer pad above the ball seat, the sealing between the ball pin and the ball seat is improved, and the service life of the ball pin seat is extended.
[0003] In order to improve the sealing and wear resistance between the ball pin and the ball seat and extend the service life of the ball pin seat, a Chinese patent (authorization announcement number: CN212055488U) discloses a highly wear-resistant and highly sealed ball pin seat. The utility model includes a base, a first sealing groove and a receiving groove are respectively provided on the top of the base, a first sealing gasket is provided in the inner cavity of the first sealing groove, a sealing plate is provided on the top of the base, through holes are provided on both sides of the top of the sealing plate, threaded holes are provided on both sides of the top of the base, and bolts are provided in the inner cavity of the through hole. The utility model achieves the purpose of good sealing effect through the cooperation of the base, the first sealing groove, the receiving groove, the first sealing gasket, the sealing plate, the through hole, the threaded hole, the bolt, the through groove, the second sealing groove and the second sealing gasket, can effectively seal the ball pin seat, effectively prevent dust from entering the ball pin seat, improve the user's experience of the ball pin seat, and meet the needs of the current market.
[0004] This solution still has some shortcomings in application. Since the ball pin is embedded in the ball seat and needs to be rotated during normal use, a gap is likely to appear between the ball pin and the ball seat during rotation, which can easily lead to dust entering the ball pin seat, especially after long-term use. At the same time, the ball pin and the ball seat are both made of steel, and the two are directly fitted and rotated, which causes rapid wear and affects the service life. Therefore, the structure of the ball pin seat needs to be improved to make it have better sealing and wear resistance. Utility Model Content
