Fore limb of pool cue

Abstract

The invention discloses a fore climb of a pool cue. The fore climb of the pool cue comprises a tubular shell and a core body. The shell is provided with a first end, a second end, a predetermined wallthickness and a long shaft extending from the first end to the second end. The shell comprises a main shell layer and an auxiliary shell layer connected to the main shell layer in an overlapped manner, wherein each shell layer is formed by fiber reinforced plastic materials, and distributed along the circumference of the shell. The main shell includes a plurality of first fiber bundles, and the first fiber bundles are parallel to the long shaft of the shell. The auxiliary shell layer also includes a plurality of second fiber bundles, and the second fiber bundles are perpendicular to the longshaft of the shell. The core body is made by plastic foam, and arranged in the shell. Therefore, the defects that wood materials do not have unidirectional grains and are non-uniform in density distribution can be improved, the fiber bundles of the main shell layer are prevented from flowing and shifting during a manufacturing process, and vibration generated when a ball is hit can be absorbed andnoise generated when the ball is hit can be reduced.

Description

technical field [0001] The invention relates to the structure of a billiard cue, in particular to a billiard cue forelimb mainly made of fiber-reinforced plastic composite material. Background technique [0002] The currently generally used billiard cue is usually composed of a forelimb (Shaft) and a rear handle (Butt). It is easy to be bent by moisture, the texture is not unidirectional, the density distribution is uneven, and the hardness cannot be adjusted, which reduces the accuracy and stability of the user's hitting. Although fiber composite materials have been used to replace wooden materials, such as those disclosed in U.S. Patent No. 4,816,203 and U.S. Patent No. 6,736,733, these cue cue forelimbs made of fiber composite materials have not only solved the problem that wooden materials are prone to moisture and bending. In addition, there is no improvement in the lack of unidirectional texture of wood materials, uneven density distribution, and inability to adjust s...
