Description

A golf cart designed to prevent hand pinching Technical Field

[0001] This invention relates to the field of golf cart technology, and in particular to an anti-pinch golf cart. Background Technology

[0002] Golf carts are an important piece of equipment in golf. To make them easy to carry and save space, golf carts are usually designed to be foldable. They are folded up for storage and unfolded when in use.

[0003] An existing telescopic folding golf putter bag includes a base frame, a pair of rear wheels, a lower main tube, and an upper main tube. The front wheels are mounted on the front end of the base frame, and a lower connector is connected to the rear end. The rear wheels are symmetrically hinged to both sides of the lower connector via rear wheel linkages. The lower main tube is connected to the top of the lower connector. The upper main tube is connected to the top of the lower main tube via the upper connector. The upper main tube can rotate on top of the lower main tube via the upper connector, and the upper main tube can retract into the lower main tube from its top. The lower main tube and rear wheels can all be folded towards the base frame via the lower connector. The lower connector... The golf cart includes a lower cover and a pair of lower helical gears housed within the lower cover, and an upper helical gear vertically positioned between the two lower helical gears and meshing with them. The two lower helical gears are respectively fixed to the ends of the rear wheel linkages of the two rear wheels. The upper helical gear is hinged to the bottom end of the lower main tube and to the front wheel frame via the front wheel linkage. The golf cart can retract the upper main tube into the lower main tube before folding, reducing the height of the folded cart and further minimizing the space occupied during transport. However, this telescopic folding golf cart has the following drawbacks:

[0004] For example, when a golf cart is used for a long time, the meshing of the lower helical gear and the upper helical gear will generate an axial component force, which increases the friction. The force exerted by the lower helical gear on the upper helical gear is prone to wear. After long-term use, the rack connection between the lower helical gear and the upper helical gear is prone to tooth breakage, causing damage and rendering it unusable. This reduces the service life of the helical gear and thus affects the use of the cart.

[0005] Secondly, during the assembly of the lower helical gear and the upper helical gear, it is necessary to ensure that the meshing between the rack of the lower helical gear and the rack of the upper helical gear is precise, which makes the installation troublesome and the assembly inconvenient.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Technical solutions

[0007] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an anti-pinch golf cart. Through the structural design of the support and sliding parts, it effectively solves the problem that in traditional golf carts, after prolonged use, the rack connection between the lower and upper helical gears is prone to tooth breakage, causing damage and rendering the cart unusable, and is also troublesome to install and assemble.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] When the handle assembly folds toward the folding assembly, the handle assembly is linked to the mating component to drive the sliding component to slide within the sliding cavity. The sliding component, through the mating component, synchronously links the front wheel assembly to fold backward toward the support component and links the rear wheel assembly to fold forward toward the front wheel assembly.

[0014] As a preferred embodiment, the connector is provided with a first linkage groove for cooperating with the first linkage part, and the first linkage groove is rotatably connected to the first linkage part.
