detailed description

The link folding structure of the present invention will be described in detail below with reference to the embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an exploded view of the link folding structure of the present invention, and Figure 2 is a schematic view thereof.

The connecting rod folding structure of the invention comprises an upper frame group 1, a lower frame group 2, a handlebar group 3 and a rocker arm group 4, and a lower joint 11 is arranged between the upper frame group 1 and the lower frame group 2, A sliding sleeve 10 is arranged between the upper frame group 1 and the rocker arm group 4. The upper frame of the upper frame group 1 is provided with a coupling 9, and the lower end of the handlebar group 3 is provided with a handle joint main body 8, a handle joint main body 8 and a combination The device 9 is connected to realize the connection between the handlebar group 3 and the upper frame group 1, and the pusher group 5 is provided between the middle portion of the handlebar group 3 and the tail portion of the lower frame group 2, and the middle portion of the lower frame group 2 and the sliding sleeve 10 A connecting rod set 6 is provided, and a tie rod group 7 is arranged between the middle portion and the lower joint 11 of the rocker arm group 4; The main body 8 is provided with a cassette 15 , and the top end of the upper frame group 1 is provided with a folding snap 12 . When unfolded, the folding snap 12 locks the cassette 15 .

The upper frame 13 is provided at the upper part of the upper frame group 1 . The lower frame of the lower frame group 2 has a lower bearing seat 14. In this embodiment, the front wheel set adopts a front wheel set that can be rotated by 180° on the side of the lower frame group.

The folding method is as follows: Press the folding snap button on the upper frame group to disengage the hook on the joint body of the handle, press the handlebar group, and fix the handlebar group around the upper frame group. When the combiner rotates downward, the push rod fixed on the handlebar group is driven to move downward, because the other end of the push rod is fixed on the tail end of the lower frame group, and when the push rod is pushed downward, the lower frame is forced Rotating upwards around the lower joint combined with the upper frame and the lower frame, and a connecting rod on the lower frame connects the lower frame with the sliding sleeve on the rocker arm set, so that the connecting rod is simultaneously upward when the lower frame rotates upward The sliding sleeve is slid upward on the upper frame, and the lower ends of the left and right rocker tubes are connected by a pull rod to connect the rocker tube to the lower joint. Therefore, when the upper part of the rocker arm group slides upward on the upper frame, the tension rod is pulled, and the left and right sides are shaken. The lower ends of the arm tubes are folded inwardly together to achieve the collapsed state as shown above (see Figures 4, 5, 6, and 7).

Since the present embodiment adopts the front wheel set which is 180° on the side of the frame group for the shaft to be folded, it is more convenient to fold, but it is necessary to rotate the front wheel set 180° in the first step when folding, which is the front wheel set. Located on the side of the upper frame (see Figure 4), then folded in one step. After folding, the front wheel set is located on the side of the upper frame group, and the folding volume is smaller.

When you want to unfold the cart, just pull the handlebar up, the pusher attached to the handlebar pulls up the lower frame and rotates around the lower joint. When the lower frame is opened, the link is pulled down. , thereby pulling the rocker arm group to slide down on the upper frame, and the lower ends of the left and right rocker arms are pushed outward by the pull rod, and when the opening is to the end, the latches on the joint body of the handle are automatically snapped into the fold. When the snaps are engaged, the display state can be achieved.

In the above embodiment of the present invention, the handle joint main body 8 is provided with a handle rotation joint 31 on both sides of the top, and the handle set 3 is coupled to the handle rotation joint 31. Due to the difference in the height of the user, there is a certain requirement for the height of the handlebar, so it is necessary To adjust the height of the handlebar, the handle joint rotary joint 31 of the present invention can be rotated and positioned on the handle joint main body 8, and the handlebar set 3 is sleeved on the handlebar rotary joint 31, so that the handlebar can be conveniently adjusted. Height, to meet the needs of people of different heights, a wider range of applications.

Referring to FIG. 1 and FIG. 2, in the above embodiment of the present invention, a locking mechanism 32 is provided between the handle joint main body 8 and the handle rotation joint 31, and the locking mechanism 32 is a knob locking member. . The locking mechanism 32 is capable of locking the handlebar rotation joint 31 so that it is fixed at a fixed angle for convenient use.

Referring to FIG. 1 , in the above embodiment of the present invention, the top end of the upper frame group 1 is provided with a receiving slot, and the snap button 12 is mounted in the receiving slot, and the snap 12 is A return spring is disposed between the accommodating grooves. The accommodating groove functions as a fixing and guiding, and the return spring functions as a reset.

Referring to FIG. 8 to FIG. 10, in another embodiment of the present invention, the top of the upper frame group 1 is provided with a latch 15 , and the handle joint main body 8 is provided with a folding snap 12 . When unfolded, the snap button 12 locks the cassette 15. The other structure of this embodiment is the same as that of the first embodiment, and the main difference between the two is the position where the snap button 12 and the cassette 15 are folded. In this embodiment, the snap button 12 is disposed on the handle joint main body 8, so that the operation of the snap button 12 is more convenient.

The difference between the embodiment is that the locking mechanism 32 is a buckle pressing member, and the locking of the handle joint 31 can be realized by pulling the buckle, and the operation is simpler.

Referring to FIG. 10, in the embodiment, the handle joint body 8 is provided with a receiving groove 81, the snap button 12 is mounted in the receiving groove 81, and the snap button 12 and the receiving portion are disposed. A return spring 82 is disposed between the slots 81. The accommodating groove 81 ensures that the snap button 12 can smoothly slide and is convenient for operation. The return spring 82 is capable of driving the snap 12 to reset.

In the above two embodiments of the present invention, the front wheel set is mounted on the front of the lower frame group 2, and the rear wheel set is mounted on the lower end of the rocker arm set 4 to constitute a complete golf cart (see Figs. 3 and 8).
