Description

Golf bag cart retractable device

【Technical field】

The utility model relates to a folding device for a golf bag cart, in particular to a structure with relatively light, simple and smooth operation.

【Background technique】

The conventional golf bag cart folding device is roughly shown in Figure 1, and a locking mechanism 10 is provided between the upper and lower cart frames 11, 12. If you want to fold it, you must first pull the latch of the locking mechanism 10. 13 pull up, and upper vehicle frame 11 is rotated forward and down, is driven by connecting (pull) bar 14,15 and rear wheel stand 16 is rotated and folded. Conversely, when wanting to unfold, then first rotate upper vehicle frame 11 upwards, drive rear wheel stand 16 to unfold by connecting (pull) rod 14,15, when turning to position, need to press down pull button 13 again, with The upper and lower vehicle frames 11, 12 are mutually locked, and the front wheel 17 is turned forward at last to complete the deployment positioning. Because the pull button 13 of the locking mechanism is located at the bottom of the upper frame 11, the position is relatively low. When the user wants to fold it, the user needs to bend down and lower his body to operate and release the pull button 13, so that the upper and lower parts can be fixed. Frame 11, 12 angles; frequent use is likely to cause user fatigue, obviously needs to be improved.

【Content of utility model】

The main purpose of the utility model is to provide a golf bag cart folding device which is easy to operate, simple and smooth, so as to improve the shortcomings of the prior art.

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

There is a connecting piece on the upper end of the lower frame, and a groove on the inner side of the connecting piece, and a groove on the inner side of the lower frame for setting a slider, and the front wheel is connected to the bottom of the lower frame;

An upper frame, the lower end of which is pivotally connected to the connecting piece, and has a long groove inside the lower end;

A rear wheel stand, one end is pivotally connected to the connecting piece, and the other end is connected to the rear wheel;

A connecting rod, connected between the slider and the upper frame;

a pull rod connected between the slider and the rear wheel stand; and

A locking mechanism, with a handle, located in the middle of the upper end of the upper frame, a locking lever, located in the middle of the lower end of the upper frame, with long slots pierced at both ends, and a linkage, hidden between the handle and the Inside the upper frame, two ends are respectively connected with both sides of the locking lever, and a spring is connected with the locking lever at one end and connected with the upper frame at the other end.

Wherein, the interlocking part of the locking mechanism is a steel cable.

The advantages and effects of the utility model are as follows: 1. When folding, because the handle of the locking mechanism is located at the upper end of the upper frame, the position is relatively high, and the user can easily operate it without bending over and lowering the body. It can reduce fatigue, and is easier and labor-saving, that is, it is lighter in operation; 2. When unfolding, after the upper and lower frames are unfolded to the angle of exhibition, the locking lever of the locking mechanism and the groove on the connecting piece will automatically It is locked with a click, and there is no need to lock the locking mechanism with one more step to position the upper and lower frames, which is relatively simple and smooth in operation.

【Detailed ways】

Please refer to Fig. 2-6 at the same time. As shown in the figure, the body structure of the ball bag cart of the present invention is symmetrical on the left and right sides. The utility model includes:

Under the vehicle frame 2, the upper end is provided with a central connecting piece 21, the connecting piece 21 section is U-shaped, the front end is an inclined surface 211, and the inner upper end has a groove 212, and the lower end of the lower vehicle frame 2 is provided with a ball bag base 22 and The inner side of the front wheel 23 is provided with a groove 24 for setting a slider 25;

An upper frame 3, the lower end of which is pivotally connected to the connecting piece 21, and has a shaft 31 inside, and a long groove 32 on the inner side of the upper frame 3;

A rear wheel stand 4, one end is pivotally connected with the connecting piece 21, and the other end is connected with a rear wheel 40;

A connecting rod 41 is connected between the slider 25 and the upper frame 3 to generate a linkage relationship between the upper frame 3 and the slider 25;

A pull rod 42 is connected between the slide block 25 and the rear wheel stand 4 to generate a linkage relationship between the slide block 25 and the rear wheel stand 4; and

A locking mechanism 5, comprising: a pull handle 51, located in the middle of the upper end of the upper frame 3; a locking lever 52, located in the middle of the lower end of the upper frame 3, with long slots 32 at both ends; a linkage 53, such as a steel cable, hidden in the pull handle 51 and the upper frame 3, the two ends of the head and tail are respectively connected with the two sides of the catch lever 52; and a spring 54, one end is connected with the catch lever 52, and the other end Then it is connected with the axle 31 of the upper frame, and the locking rod 52 can be pulled down, and can be locked with the connecting piece groove 212 .

According to the combination of the above structures, the utility model is unfolded as shown in Figures 2 and 3. At this time, the spring 54 of the locking mechanism is in a compressed state, and the locking lever 52 is snapped into the groove 212, as shown in Figures 4-6. Show. When you want to fold it, just pull the handle 51 upwards, as shown by the arrow in Figure 4, the linkage 53 will drive the locking lever 52 to move upwards along the long groove 32, so as to break away from the groove on the connecting piece. 212, and then turn the upper frame 3 forward and down and release the pull handle 51, as shown in Figures 7 and 8, make the catch lever 52 slide down along the slopes 211 on both sides of the connecting piece, and be held by the spring 54 The recovery force produced by the boost effect can assist the upper frame 3 to fold down, and at the same time, the connecting rod 41 pushes the slider 25 to slide forward on the lower frame 2, and the slider 25 is also synchronously pulled by the pull rod 42 The rear wheel stand 4 rotates forward and inward, so that the rear wheel 40 is also forward and inwardly retracted, and finally the front wheel 23 is downwardly and inwardly rotated to be positioned under the lower frame 2. As shown in Figure 9, the folding is completed.

Conversely, when desiring to launch, then first the front wheel 23 is upwardly rotated and positioned outwards, and then the upper frame 3 is pulled upwards, and the connecting rod 41, the slide block 25, the pull rod 42 and the rear wheel stand 4 etc. The linkage of the sliding block 25 to the connecting piece 21 makes the rear wheel 40 unfold and position. When the frame 3 is pulled up, the catch lever 52 will slide upward along the slope 211, forcing the spring 54 to pull Stretch until the catch lever 52 slides to the upper end of the groove 212, then the restoring force of the spring 54 makes the catch lever 52 slide into the groove 212, so that the upper frame 3 is launched and positioned, and the upper and lower frames 3, 2 lock each other to complete the deployment and positioning, as shown in Figures 2, 3 and 6.
