Description

Golf bag cart retractable device

【Technical field】

The utility model relates to a folding device for golf bag carts, especially a device in which the front wheels can be synchronized with the rear wheels when folding, so as to omit the additional step of folding the front wheels again, so as to prevent the user from being soiled. Achieve the effect of easy operation.

【Background technique】

Conventional golf bag carts, after the overall frame is folded, need to additionally fold the front wheels. According to the action, it can be roughly divided into: 1. Rotate the front wheel by a rotating shaft to make it close to the rear wheel , for example: U.S. Patent No. 6,698,789B2, 2. There are two ways to disassemble the front wheel; and the way to disassemble the front wheel will have the problem of reassembly, and will cause the trouble and trouble of losing the front wheel parts; moreover, For the two folding methods, the user needs to bend over or squat, keep the frame in a specific tilt state with one hand, and fold (disassemble) the front wheel with the other hand. Not only is the operation cumbersome and the posture is bad, but also It is easy to dirty the user's body or clothing, which is obviously troublesome and inconvenient, and needs to be improved.

【Content of utility model】

The main purpose of this utility model is to provide an easy-to-operate folding device for golf bag carts, so that when the frame is folded, the front wheels can be synchronized with the rear wheels, so as to omit the step of folding the front wheels, and can Prevents the user from being soiled.

A folding device for a golf bag cart, characterized in that it includes:

Once on the frame, there is a handle pipe at the upper end;

A rear wheel foot frame, which is connected with the upper frame by a connecting piece, and has a rear wheel at the lower end;

A tie rod, connecting the upper frame and the rear wheel kickstand;

The lower frame is connected with the upper frame and has a front wheel at the lower end; and

A link mechanism, located between the upper and lower frames; when retracting, the link mechanism is linked to make the lower frame and the front wheels move closer to the rear wheels, so as to omit the step of retracting the front wheels .

Wherein, the bottom end of the upper frame has an adapter seat.

Wherein, the linkage mechanism includes:

The lower frame is connected with the upper frame;

A second connecting rod, connecting the upper and lower frames;

a third link connecting the lower frame to the front wheel; and

A fourth connecting rod, connecting the second and third connecting rods.

The utility model has the advantages and effects of providing an easy-to-operate folding device for golf bag carts, so that when the frame is folded, the front wheels can be synchronized with the rear wheels, so as to omit the step of folding the front wheels and prevent dirty the user.

Shown in Fig. 1 is the perspective view of the utility model.

Figure 2 is a schematic diagram of the action when the utility model is folded.

Figure 3 is a schematic side view of the utility model after being folded.

The symbols in the figure are explained as follows:

1 upper frame 11 upper seat 12 handle pipe

13 adapter seat 2 rear caster frame 20 rear wheel

21 connecting piece 22 tie rod 3 lower frame

30 front wheel 31 base seat

32, 33, 34 linkages 4 linkages

【Detailed ways】

Please refer to shown in Fig. 1-2, the utility model comprises:

An upper frame 1, the upper end has an upper bearing seat 11, and can be connected with a handle pipe 12, and the bottom end has an adapter seat 13;

A rear wheel stand 2, the upper end is connected with the upper frame 1 by a connecting piece 21, and the lower end is connected with the rear wheel 20;

A pull rod 22 is connected between the bottom end of the upper frame 1 (the adapter seat 13) and the rear wheel stand 2;

Lower frame 3, one end is connected with upper frame 1 (transfer seat 13), and the other end has a bottom bearing seat 31, and is connected with a bottom frame 33, and this bottom frame 33 end is connected with front wheel 30 ;and

A link mechanism 4, located between the upper and lower frames 1, 3, including: a first connecting rod, which is the lower frame 3; a second connecting rod 32, connected to the upper and lower frames 1, 3, 3; a third connecting rod, which is the bottom frame 33, connected with the lower frame 3; a fourth connecting rod 34, connected between the second and third connecting rods 32, 33, and the first , The second, the third, the fourth connecting rod 3,32,33,34 and constitute a parallel four connecting rod.

When folding, lift the lower frame 3 upwards and push the connecting piece 21 by the second connecting rod 32 to pull the rear wheel stand 2 so that the rear wheel 20 is retracted inward; on the other hand, due to the lower frame 3 and the third The connecting rod 33 is connected, and the other end of the third connecting rod 33 is connected to the fourth connecting rod 34, and because the lower frame 3 and the second, third and fourth connecting rods 32, 33, 34 are a parallel four-link , so when folded, the fourth connecting rod 34 will maintain a state parallel to the lower frame 3, so that when the lower frame 3 is lifted up, the fourth connecting rod 34 will be linked to make the lower frame 3 and the lower frame 3 The third connecting rod 33 is gradually folded, and drives the front wheel 30 to move towards the connecting piece 21, so that the front and rear wheels 30, 20 are gradually approached, as shown in Figure 2; It is in a folded state, and the front wheel 30 is moved towards the direction of the rear wheel 20 along with the four-bar linkage mechanism 4. The whole also presents a state of tight fit and small volume.

Therefore, it can be seen from the above description that when the present embodiment is folded, as long as the lower frame 3 is lifted upwards, the lower frame 3 and the second, third, and fourth connecting rods 32, 33, and 34 can be used. The four-bar linkage mechanism 4 synchronously drives the front wheels 30 and the rear wheels 20 to move closer together, and the folded state of the upper and lower frames 1 and 3 is not only quite easy to operate, but also can omit the step of folding the front wheels 30 again. , and prevent the user's body or clothing from being soiled, it is obviously far more advanced than those who know it.

In short, the main features of the utility model are: (1) the front wheels are fixed on the lower frame, (2) a link mechanism is arranged between the upper and lower frames; The link mechanism can fold the lower frame, and make the front wheels close to the rear wheels synchronously, so as to save the additional step of folding the front wheels again, prevent the user's body or clothes from being soiled, and achieve the effect of easy operation .
