detailed description

The structure of the present invention will be further described below in conjunction with the drawings and preferred embodiments.

Referring to Figures 1 to 10, the present invention also includes a front wheel 1, a left wheel 2, a right wheel 3, a backbone bracket 4, a column bracket 5, and a handle bracket 6 with respect to the existing folding structure golf cart. The specific structure of the present invention is that the front wheel 1 is connected to the front end of the backbone bracket 4 through the front fork bracket 11 , and the lower bracket 12 is provided with a lower bracket 12 for fixing the golf bag The bottom end. The spine bracket 4 is sleeved with a side wheel connecting sliding sleeve 7, and the left side of the side wheel connecting sliding sleeve 7 is hinged with a left wheel bracket 21, and the other end of the left wheel bracket 21 is hinged with a left wheel connecting block 22, and the left wheel connecting block 22 is The axle of the left wheel 2 is connected; the right side of the side wheel connecting sleeve 7 is hinged with a right wheel bracket 31, and the other end of the right wheel bracket 31 is hinged with a right wheel connecting block 32, and the right wheel connecting block 32 is The axle of the right wheel 3 is connected.

The bottom end of the column bracket 5 is hinged to the rear end of the spine bracket 4, the top end of the column bracket 5 is hinged with the handle bracket 6, and the top bracket 54 is also connected with an upper bracket 54 on the top of the pillar bracket 5 The frame 54 is used to secure the upper end of the golf bag.

In order to realize the folding control when the column bracket 5 is folded, the left side wheel 2 and the right side wheel 3 are synchronously gathered in the middle, and the column bracket 5 and the side wheel connection sliding sleeve 7 are arranged to push the side wheel connection during the folding process of the column bracket 5 The first linkage rod 51 that is moved forward by the sleeve 7 is provided between the ridge support 4 and the left wheel bracket 21, and the second linkage rod 23 that pulls the left wheel bracket 21 to be folded inward during the forward movement of the side wheel connection sliding sleeve 7 is also provided. That is, according to the triangle principle, since the length of the second linkage rod 23 is fixed, the second linkage rod 23 will pull the left wheel bracket 21 to be deflected backward when the side wheel connection sliding sleeve 7 moves forward, and the left side wheel 2 is folded in the middle, on the side. When the wheel connecting sliding sleeve 7 is moved backward, the second linkage rod 23 pushes the left wheel bracket 21 to open; similarly, between the backbone bracket 4 and the right wheel bracket 31, when the side wheel connecting sliding sleeve 7 is moved forward, the pulling is performed. The right wheel bracket 31 is folded inwardly to the third interlocking lever 33.
