Abstract

The utility model discloses a three-folded structure of golf cart, mainly refers to a foldable and collapsible structure of the lower bracket and the bottom bracket thereof. The three- folded structure consists of an upper bracket, an upper belt dochium, a lower bracket, a left wheel axle and a right wheel axle, a lower belt dochium, a pivoted dochium, and a bottom bracket. When taking the top of the pivoted dochium as fulcrum collapses towards the bottom bracket, the lower bracket slides forward simultaneously by right of the combining movement of the middle connecting rod and the slide, and relatively ensures the connecting rods of both sides and the left and the right wheel axles and the left and the right wheels to do combining movement and collapse inwards together. Therefore, not only the size of the three-folded structure is reduced after being collapsed, but the folding movement is steady and smooth due to the cooperation of the slide fixed on the bottom bracket to drive the middle connecting rod and connecting rods of both sides to finish the folding movement; in addition, if the packing space needs to be further reduced, the locking elements can be unscrewed and the left and the right wheel axles and the left and the right wheels can be disassembled to further save the packing materials to be more convenient for packaging and transportation.

Description

The foldable structure of three-bend golf cart

Technical field

The utility model means a kind of foldable structure of three-bend golf cart, and to save the volume, its jackknife action is also very simple than steady and smooth and operation, and is quite convenient for the user except collapsible.

Background technology

The golf cart of commonly using is adjusted though wherein the body of rod 71 of upper bracket 7 is can be in lower carriage 8 flexible up and down as shown in Figures 1 to 4, and lower carriage 8 also can fold reducing the volume of timber to lower supporter 9 is folding, yet still there is following disappearance in it:

1, the body of rod 71 of upper bracket 7 is to stretch into mat adjustment screw 70 lockings again of lower carriage 8 inside, through looking into, the load of carrying the golf bag that golf clubs is housed is quite heavy, make the steadiness at this position relatively poor relatively, and more be easy to generate loosening situation after using a period of time, relatively also reduce service life.

2, when golf bag 80 be seated in usher to seat 81 with under usher to seat 91 the time, because all bodies of rod 71,82,92 are to be a straight line, so the bar head 901 of each golf clubs 90 of being placed in the golf bag 80 is easy to run into the body of rod 71 of upper bracket 7 belows and the situation of generation noise or wearing and tearing.

3, when lower carriage 8 desires fold with lower supporter 9 (referring to figs. 2 to Fig. 4), must earlier pressure handle upwards be pulled open, make its locating ring break away from the location grab of lower supporter 9 then, lower carriage 8 is folded to lower supporter 9, therefore operate trouble.

Summary of the invention

Main purpose of the present utility model provides the foldable structure of a kind of jackknife action than steady and smooth and easy to operate three-bend golf cart.

To achieve these goals, solution of the present utility model is: a kind of foldable structure of three-bend golf cart, mainly mean the folding retracting structure of its lower carriage and lower supporter, wherein this golf cart system includes: a upper bracket, its top tool handle, the below then is to articulate with the top of lower carriage, and can be by the adjustment of the control handle of adjusting device fixing or loosen; Usheing to seat on one, is the below predetermined position that is located at upper bracket; One lower carriage, the side of fastening articulates with upper bracket; One revolver axostylus axostyle and right axle rod are respectively by the left and right wheel that is pivoted outside it; Once usheing to seat, is the front side that is located at lower supporter; One pin joint seat; One lower supporter is to be installed with by its front side to usher to seat; Be characterized in: this lower carriage, the top of system's below mat pivot and pin joint seat articulates, and its below has a positioning rod in addition can be arranged in the locating groove of limitting casing of pin joint seat and inlay card location, and the below predetermined position of this lower carriage is connected with the top of middle connecting rod in addition; This left and right axle rod is that each connects a body by its inboard mat lock member, and the inboard pivot joint wall with the pin joint seat both sides of each body of mat articulates; This pin joint seat, cording has going up of vertical direction opening to articulate wall, but mat pivot and lower carriage articulate, its both sides, below then respectively have the pivot joint wall that approaches the horizontal direction opening to articulate with the inboard of left and right axle rod respectively, and this pin joint seat and mat torque spring card are established a limitting casing, this limitting casing then is that a side mat axostylus axostyle passes torque spring, make a side of torque spring be resisted against the top, front side that articulates wall, its opposite side then dogging at the suitable position of the two side of this limitting casing, but and the two side respectively have the backstay of locating groove inlay card lower carriage below; This lower supporter, it is the slide of rear side predetermined position sheathed one slippage above it, and the middle upper part of this slide system is connected with the below of middle connecting rod, the both sides of slide then respectively with the side pivot joint of side connecting rod, be connected with the predetermined position of left and right axle rod by its opposite side respectively again.

Because above structure, the utility model can be concluded has following effect:

1, lower carriage 2 is that fulcrum is when lower supporter 5 directions fold with pin joint seat 4 tops, connecting rod 61 interlock slide 50 slippages forward in the mat simultaneously, also left and

right axle rod

31,32 of interlock and left and

right wheel

33,34 inwardly fold simultaneously and make both

sides connecting rod

62,63 relatively, therefore not only folding volume after folding dwindles, and since cooperate the slide 50 be located at lower supporter 5 drive in connecting rod 61 finish aforementioned jackknife action with both

sides connecting rod

62,63, so its jackknife action is than steady and smooth.

2, the minimizing packaging space can unscrew

lock member

35,36 and left and

right axle rod

31,32 is dismantled more convenient packing and hauling operation with further saving packing material together with left and

right wheel

33,34 if desire further.

3, lower carriage 2 is easy to operate with folding of lower supporter 5, as long as can make the backstay 22 of lower carriage 2 break away from its locating groove 4002 and fold jackknife action with the foot-operated rear side 4003 of limitting casing 40 of pressing.
