Refer to Fig. 1,3 when bracket 3 and grip handle 1 are away from wheel carrier 2, and bracket 3 is located between a pair of first upright bar 11, support Frame 3 is located at the top of supporting rod 10 and 10 Support bracket 3 of supporting rod backwards to the end of bracket 3.Wheel carrier 2 is fixed with the second claw 21, Second claw 21 includes a pair of second elastic arm with free end, and when grip handle 1 is close to wheel carrier 2, the first upright bar 11 accommodates Between a pair of second elastic arm.

Fig. 4 is referred to, 5 bracket, 3 lower surface is fixed with the first claw 31, and claw includes a pair of first bullet with free end Property arm, when bracket 3 and grip handle 1 are away from wheel carrier 2, supporting rod 10 is contained between a pair of first elastic arm, and supporting rod 10 is Circular bar or pipe.First claw 31 further includes the connecting portion between a pair of of elastic arm, and connecting portion is in the following table of bracket 3 Face.

Branch foot lever 14 is fixed between the lower end of a pair of first upright bar 11.

There is the frictional force for being used for keeping 4 position of sack frame between sack frame 4 and grip handle 1 or wheel carrier 2.

Fig. 7 is referred to, the first upright bar 11 that the folding of the utility model second embodiment is pulled a cart includes upper boom 111 and lower beam 112, upper boom 111 and lower beam 112 are hinged by rotating connector 13.

Please also refer to Fig. 8 and Fig. 9.Rotating connector 13 includes handle rotation and switchs the 131, first turntable 133, limiting tooth 135 and second turntable 137 of wheel, the first turntable 133 are fixedly connected with one of upper boom 111 and lower beam 112, the second turntable 137 are fixedly connected with therein another of upper boom 111 and lower beam 112.First turntable 133 can be 137 turns relative to the second turntable It is dynamic or fixed.

Handle rotation switch 131 is installed on the first turntable 133, and positioned at the first turntable 133 and 135 phase of position limited gear To side, it is used to promote position limited gear 135 to move in the first turntable 133 and the second turntable 137, so that the first turntable 133 rotate or fix relative to the second turntable 137.Handle rotation switch 131 includes button portion 131a, clamping part 131b and body 131c, body 131c are generally cylindrical structure, and button portion 131a and clamping part 131b are respectively arranged at two of body 131c Opposite side, the quantity of clamping part 131b is multiple, it extends parallel to the axis direction of body 131c along body 131c peripheries, Clamping part 131b passes through the first turntable 133, and offsets with position limited gear 135.

Limiting section 133b is convexly equipped with first turntable 133, limit hole 135a is offered on the end face of position limited gear 135, is limited Position portion 133b can be placed in limit hole 135a, to limit the moving range of position limited gear 135.

Position limited gear 135 can engage with the first turntable 133 and the inside of the second turntable 137, and be located at the first turntable 133 and the Between two turntables 137.The 137 interior space being equipped with for accommodating position limited gear 135 of first turntable 133 and the second turntable, first turn The madial wall of disk 133 is equipped with can coordinate spacing internal gear 133a with position limited gear 135, on the madial wall of the second turntable 137 Equipped with spacing internal gear 137a can be coordinated with position limited gear 135；The centre of accommodating space is additionally provided with second turntable 137 Shaft 137b, cylinder generally hollow shaft 137b, and towards position limited gear 135.135 and second turntable of position limited gear Spring (not shown) is equipped between 137, the spring pocket is arranged on the shaft 137b of the second turntable 137, and is arranged at position limited gear 135 and second between turntable 137.One end of the spring and the inner face of the second turntable 137 offset, the other end and limiting tooth Wheel 135 is supported close to the end face of the second turntable 137, spring can make position limited gear 135 at the same time with the first turntable 133 and second turn Internal gear 133a, 137a engagement on disk 137；Position limited gear 135 and the shape of internal gear 133a, 137a are coincide, position limited gear 135 can be contained in internal gear 133a, 137a.

Position limited gear 135 at the same time with when internal gear 133a, 137a are engaged in the first turntable 133 and the second turntable 137, first The position locking of 133 and second turntable 137 of turntable.When pressing the button portion 131a of handle rotation switch 131, spring is compressed, And certain elastic potential energy is accumulated, the clamping part 131b of handle rotation switch 131 promotes 135 and first turntable 133 of position limited gear On internal gear 133a separation, and position limited gear 135 is fully entered in the second turntable 137, at this time, the second turntable 137 can phase Rotated for the first turntable 133, so that adjustable angle between upper boom 111 and lower beam 112, realizes the folding for holding connecting rod 11 It is folded.When unclamp handle rotation switch 131, spring release elastic potential energy, 135 return of position limited gear, at the same with the first turntable 133 and Internal gear 133a, 135a engagement in second turntable 137, the second turntable 137 can not be rotated relative to the first turntable 133, upper boom 111 are relatively fixed with lower beam 112.

In order to make position limited gear 135 preferably realize limit function, the centre of accommodating space is set in the first turntable 133 There is a shaft 133c, the centre of accommodating space is equipped with shaft 137b, shaft 133c, 137b and limiting tooth in the second turntable 137 The axis of wheel 135 coincides, and position limited gear 135 is sheathed in shaft 133c, 137b, and shaft 133c, 137b can make the first turntable 133 relative to 137 smooth rotation of the second turntable.In order to make spring have more preferable working effect, prevent the axis of spring from occurring partially Move, obtain and more stablize elastic force, annular groove is opened up in the end face of position limited gear 135 towards spring, spring pocket is arranged on shaft 137b Upper and one end is contained in the annular groove.The both ends of spring can be fixed with 135 and second turntable 137 of position limited gear respectively.

Refer to the three-dimensional structure diagram that the folding of Figure 10 the utility model 3rd embodiments is pulled a cart.Wheel carrier 2 includes vertical side To the second upright bar 21 of setting, the first upright bar 11 and the second upright bar 21 are telescopic rod.

In the utility model, the bracket is hinged with the wheel carrier lower end, and the wheel carrier upper end in the middle part of grip handle with cutting with scissors Connect, the grip handle includes a pair of first upright bar, the supporting rod for the lower part being fixed between a pair of first upright bar, when described When bracket and the grip handle are away from the wheel carrier, the bracket is between a pair of first upright bar, and the bracket is backwards The end of the bracket is located above the supporting rod and bracket described in the they sup-port.When pulling a cart to be unfolded, grip handle Big with the angle of bracket, grip handle being capable of more preferable Support bracket.

In one embodiment of the utility model, when pouch and fixed at the same time sack frame, bracket, user is led to Cross lifting sack or sack frame can foldable bracket and sack frame.

More than, be only the utility model preferred embodiment, limit in any form not is made to the utility model System, although the utility model has been disclosed with preferred embodiment as above, but is not limited to the utility model, any to be familiar with sheet Technical professional, is not departing from the range of technical solutions of the utility model, when the technology contents work using the disclosure above Go out a little change or be modified to the equivalent embodiments of equivalent variations, as long as be without departing from the content of the technical scheme of the utility model, according to Any simple modification, equivalent variations and the modification made according to the technical essence of the utility model to above example, still fall within In the range of technical solutions of the utility model.
