Therefore, the golf cart we have designed is dedicated to solving the above two problems. This cart can be used to gather the car in one step, and it can be deployed in one step. And because the sliding and folding mode of the car can effectively solve the volume problem after the folding, the volume after the folding is small. In addition, there are two types of push-pull ball cars that are currently available. One is that the push rod is fixed between the handle and the rocker arm. When adjusting the height of the handlebar, the rear wheel track is also changed, and the influence is affected. The balance of the car; the other is that the push rod is fixed between the front fork and the rocker arm, and the height of the handlebar is adjusted without affecting other parts of the car, but this method needs to be more separate when folding the car. The steps that are taken will cause the folding process to be cumbersome.

The folding device includes a button holder 20 mounted on the upper portion of the upper frame group 3, a folding snap 16 and a positioning pin 21 therein, and a cassette 23 mounted on the side of the upper joint 2 (see Fig. 6).

The front wheel set includes a front wheel fork frame 91 and a front wheel leveling and quick-loading device (see FIG. 9). The front wheel leveling and quick-loading device includes a fixing pin 96, a spring 93, a rotary slider 94, a movable pin 98, and a fixed Block 95 and fixing bolt 97 (see Fig. 8), a rear end of the front fork frame 91 has a tube 92 in which a fixing pin 96 and a spring 93 are sequentially mounted, and a rotary slider 94 is sleeved outside the straight tube 92, and the fixing block 95 is placed over Outside the rotary slider 94, the fixing bolt 97 is fixed through the rotating slider 94 and the corresponding hole on the straight pipe 92, and the movable pin 98 penetrates the long axial groove on the rotary slider 94 and the long axial groove on the straight pipe 92. And a 90° slot extending from the vertical axis of the fixing block 95. The front end of the fixing block 95 is provided with a connecting iron core 99. The iron core 99 has a card slot, and the rear end of the rotating slider 94 is provided with a square disk corresponding to the fixing block 95. The front side of the type disc is provided with a positioning convex; the front wheel fast mounting seat 13 is provided with a square deep hole 133 corresponding to the fixing block 95, and a quick-fit snap button 131 and a button spring 132 are arranged therein, and the square deep hole 133 is evenly distributed four times. Positioning slots.

A handlebar height adjustment device is provided on the handlebar set 1, and the handlebar height adjustment device includes a handlebar joint 24 disposed between the handlebar tube set 1 and the push rod 4, and a left and right toothed disc 17 on the handlebar tube set 1. , the corresponding toothed disc in the handle joint 24, the joint bolt across the toothed disc

22, the joint bolt 22-end with a rotating buckle 18 (see Figure 6).

The upper seat 15 is a multi-functional socket having two symmetrical grooves 151 (see Fig. 10) on the curved surface of the arc-shaped socket. The folding method is as follows: Press the snap button 18 on the snap socket 20 to disengage the latch 23 on the handle joint 24 from the snap socket 20, press the handle tube set 1, and the handle tube set When the upper joint 2 fixed to the upper frame group 3 is rotated downward, the push rod 4 fixed to the handle joint 24 is moved downward, because the other end of the push rod 4 is fixed to the lower frame group 8 Above, when the push rod 4 is pushed downward, the front end of the lower frame group 8 is forced to rotate upwards around the lower joint 6, and the lower frame group 8 has a sliding sleeve link 7 to lower the lower frame group 8 and the rocker arm group. The sliding sleeve 5 of the 10 is connected, so that the sliding sleeve connecting rod 7 simultaneously pushes the sliding sleeve 5 of the rocker arm group 10 to slide upward on the upper frame group 3 while the front end of the lower frame group 8 is rotated upward, and the lower end of the left and right rocker tubes All the pull rods 12 connect the rocker tube to the upper frame group 3, so when the upper part of the rocker arm group 10 slides upward on the upper frame 3, the tension rod 12 is pulled, and the lower ends of the left and right rocker tubes are closed inwardly. The collapsed state can be achieved (see Figure 5, Figure 11).

When you want to unfold the cart, just pull the handle to lift the tube set 1 and connect the push rod 4 on the handle tube set 1 while pulling up the lower frame group 8 to rotate around the lower joint 6. The lower frame When the group 8 is opened, the sliding sleeve connecting rod 7 is opened downward, so that the rocker arm group 10 is pulled down on the upper frame, and the lower ends of the left and right rocker tubes are pushed outward by the pulling rod 12, when the opening is reached. When the latch 23 on the joint 24 is automatically snapped into the positioning pin 21 in the folding snap 18, the unfolded state can be achieved (see Fig. 2). The height adjustment of the handlebar is as follows: When it is desired to adjust the height of the handlebar, the rotary toggle 18 can be loosened to disengage the left and right spurs 17 from the corresponding spurs in the handlebar joint 24, thereby adjusting the height of the handlebar. When the desired height is adjusted and then the rotating buckle 18 is locked, the left and right toothed discs are twisted with the corresponding toothed discs in the handlebar joint 24, and the handlebar set 1 can be fixed. Since the push rod 4 is fixed to the handle joint 24, when the height of the handle is adjusted, the position of the upper joint is not affected, that is, the upper joint does not move, so it does not affect other parts of the vehicle (see Figure 7).

This cart can fold the car in one step (see Figure 5), and it can be deployed in one step instead of the reverse direction. And because the car's sliding folding method can effectively solve the volume problem after folding, the volume is small after folding (see Figure 11).

The golf cart can achieve the one-step folding by the action of the push rod when the handle is closed, and the height adjustment device of the handle can be independent, and the height of the handle can be adjusted without affecting other parts of the vehicle, thereby causing the vehicle to be unbalanced.

In addition, the car has a unique design, that is, the car's upper seat is a multi-functional upper seat. Currently, two types of golf bags are popular in the market, namely, ordinary type and support type. The seat used in the current car can only be used on a common type of bag. When the bag with the support type is to be fixed, the support frame on the bag will interfere with the seat and cannot be fixed. The upper seat we designed can effectively avoid the support frame on the bag and firmly hold the bag. It can also be used for ordinary golf bags.

In addition, the car also has a structure that effectively reduces the volume, that is, the front wheel can be flattened by 90 degrees after folding, which can effectively reduce the size of the car after the car is closed, so that the user can conveniently transport and store. .

Industrial applicability

The utility model provides a new type of golf cart for the market and the golf manufacturer. The golf cart has the function of one-step folding, which takes up less storage space after folding, is convenient for storage and transportation, and can adjust the handle when used. Height, and can be applied to a variety of golf bags.
