Problems solved by technology

[0002] The ball head shaft is a part that is often used on plastic shell products. There are ball heads at both ends of the rotating parts in plastic shell products. The ball heads are placed in the shaft holes of the base of plastic shell products. In the case of long-term use Under normal conditions, the ball head is easy to loosen in the shaft hole. After loosening, the rotating part will shake left and right. In severe cases, the rotating part will break away from the base.

Embodiment Construction

[0022] Please refer to figure 1 , which discloses a plastic shell product 10 according to an embodiment of the present invention. The plastic shell product 10 includes a rotating member 100 and a body 200 . .

[0023] The ball head rotating shaft 110 comprises two ball heads 120 and two axle holes 210, the ball head 120 is made up of a hemispherical first sphere 121 with a smaller radius and a hemispherical second sphere 122 with a larger radius, the first sphere 121 and the second sphere The two balls 122 face the same direction and intersect to form an annular intersection line 123. The two ball heads 120 are coaxially arranged on the circular bosses 130 at both ends of the rotating member 100. The two shaft holes 210 are circular holes 211 arranged on the body 200. The radius of the hole 211 is adapted to the radius of the circular intersecting line 123 , and the opposite ends of the two holes 211 have an inner surface 212 adapted to the outer surface of the second sphere ...

Abstract

The invention discloses a shell product with a ball head rotating shaft, which comprises a rotating piece, a body and a ball head rotating shaft, and is characterized in that: the ball head rotating shaft comprises two ball heads and two shaft holes; each ball head consists of a semi-spherical first ball body with a small radium and a semi-spherical second ball body with a big radium, and the first ball body and the second ball body are crossed to form an annual intersected line; the two ball heads are coaxially arranged at two ends of the rotating piece; the two shaft holes are round holes in the body; the radius of the holes is consistent with the radius of the annual intersected line; and the holes have internal surfaces consistent with the external surfaces of the second ball body. The shell product with the ball head rotating shaft makes the ball head rotating shaft have combined advantages of axial limiting and radial tensile strength, so that the rotating piece can be hinged on the body firmly.

Description

technical field [0001] The invention relates to a ball head rotating shaft of a plastic shell product. Background technique [0002] The ball head shaft is a part that is often used on plastic shell products. There are ball heads at both ends of the rotating parts in plastic shell products. The ball heads are placed in the shaft holes of the base of plastic shell products. In the case of long-term use Under normal circumstances, the ball head is easy to loosen in the shaft hole, and the rotating part will shake left and right after loosening, and the rotating part will break away from the base in severe cases. Contents of the invention [0003] In view of this, the present invention provides a shell product with a ball joint shaft. [0004] A shell product with a ball joint shaft, including a rotating member, a body and a ball joint shaft, characterized in that the ball joint shaft includes two ball joints and two shaft holes, and the ball joint is composed of a hemispher...
