Description

Technical Field

[0001] The utility model relates to the field of golf trolleys, in particular to an anti-hand pinching golf trolley. Background Art

[0002] A golf cart is one of the important equipment for golfing. In order to be easy to carry and save carrying space, a golf cart is usually designed to be foldable. When storing, the golf cart is folded up and unfolded when in use.

[0003] An existing telescopic and foldable golf cart comprises a chassis, a pair of rear wheels, a lower main pipe and an upper main pipe. The front end of the chassis is equipped with a front wheel, and the rear end is connected to a lower connecting piece. The rear wheels are symmetrically hinged on both sides of the lower connecting piece through a rear wheel connecting rod. The lower main pipe is connected to the top of the lower connecting piece. The upper main pipe is connected to the top of the lower main pipe through the upper connecting piece. The upper main pipe can be rotated on the top of the lower main pipe through the upper connecting piece, and the upper main pipe can be retracted from the top of the lower main pipe into the interior of the lower main pipe. The lower main pipe and the rear wheels can be folded toward the chassis through the lower connecting piece. The lower connecting piece includes The golf cart comprises a lower cover and a pair of lower bevel gears disposed therein, and an upper bevel gear disposed vertically between the two lower bevel gears and meshing with the lower bevel gears. The two lower bevel gears are respectively fixed to the ends of the rear wheel connecting rods of the two rear wheels. The upper bevel gear is hinged to the bottom end of the lower main pipe and is hinged to the front wheel frame through the front wheel connecting rod. The golf cart can be folded after the upper main pipe is retracted into the lower main pipe, which can reduce the height of the golf cart after folding and further reduce the space occupied during transportation. However, this telescopic and foldable golf cart has the following defects:

[0004] For example, when a golf cart is used for a long time, an axial force component is generated when the lower bevel gear and the upper bevel gear are meshed, which increases the friction. The force exerted by the lower bevel gear on the upper bevel gear is likely to cause wear. After long-term use, the rack connection between the lower bevel gear and the upper bevel gear is likely to cause teeth to come off, causing damage and unusability, reducing the service life of the bevel gear and thus affecting the use of the cart.

[0005] Secondly, when assembling the lower bevel gear and the upper bevel gear, it is necessary to ensure that the meshing between the rack of the lower bevel gear and the rack of the upper bevel gear is accurate, which makes the installation troublesome and the assembly inconvenient.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
