Abstract
The utility model relates to a three-wheel handcart which has an elastic buffer function and can absorb shaking force for preventing babies from bruising, comprising a front vehicle frame, a back vehicle frame, a pushing handgrip, a group of coupled rods, a front wheel and back wheels. The front vehicle frame and the pushing handgrip are assembled and provided with a seat sleeve; the back vehicle frame is fixedly connected with a connecting rod; a left frame rod, a right frame rod and the bottom of the connecting rod are pivoted with a wheel seat; the back wheels are respectively pivoted at one side of the wheel seat; one side of the left frame rod and the right frame rod are provided with a buffer element; the other end of the buffer element is fixedly connected to the wheel seat which forms a long slot hole on the pivot joint position with the left frame rod and the right frame rod.
Description
The utility model relates to a kind of buggy.
As shown in Figure 1, it is a kind of baby stroller 10 of the usefulness of in the past going out to ride instead of walk, be arranged with a seat support 12 and a sunshield 13 at a front vehicle frame 11 end faces, and these front vehicle frame 11 front ends are installed in a underframe 14 front sides, and at these underframe 14 forward and backward wheels 15,16 that respectively are provided with, be installed with two poles 17 at these underframe 14 rear sides, tie on front vehicle frame 11 these pole 17 upper ends then pivot, in order to support front vehicle frame 11, then be installed with a handle 18 in these front vehicle frame 11 upper ends in addition, by this, can reach carrying infant's purpose.But in use, if when running into rugged road surface or foreign object strike, the shaking force that this wheel 15,16 is suffered, can directly be delivered to front vehicle frame 11 by this pole 17, make the infant who rides in this seat support 12 also bear identical vibrations, it is uncomfortable to cause the infant to take, even may excessive it be clashed into because of shaking.
But the purpose of this utility model is to provide a kind of absorbing vibration power, to prevent the buggy of the tool elastic buffer effect that the infant wounds.
The buggy of a kind of tool elastic buffer of the present utility model effect, comprise a front vehicle frame, an one back vehicle frame and a handle, before being somebody's turn to do, be provided with one group of trace between back vehicle frame, and before this, before back frame end respectively is provided with, rear wheel, group is provided with a seat webbing on this front vehicle frame and the handle, it is characterized in that: this back vehicle frame is on a left side, be consolidated with a union lever between right hack lever, on this left side, right hack lever and union lever bottom pivot have a wheel seat, this rear wheel is hubbed on a side of wheel seat respectively, on this left side, right hack lever one side is provided with a buffer element, this buffer element other end then is cemented on this wheel seat, this wheel seat with a left side, right hack lever pivot knot place forms a long slot bore.
The buggy of described tool elastic buffer effect is characterized in that: this wheel seat one side is provided with one for the fixed mounting groove of this buffer element embedding.
The buggy of described tool elastic buffer effect is characterized in that: fixed union lever is to be inverted U between this left and right hack lever.
The buggy of described tool elastic buffer effect is characterized in that: this buffer element is a spring.
The effect of the buggy of tool elastic buffer of the present utility model effect is that when this wheel was subjected to the external force of an impact, this left and right hack lever can pivot in wheel seat, and this impulsive force of pulling buffer element generation distortion absorption, thereby prevented that the infant from being wounded.
, be elaborated to the buggy of the utility model tool elastic buffer effect below by most preferred embodiment and accompanying drawing, in the accompanying drawing:
Fig. 1 is the schematic perspective view of hand barrow in the past.
Fig. 2 is the combination schematic perspective view of the utility model preferred embodiment.
Fig. 3 is the part perspective exploded view of wheel seat in the utility model preferred embodiment, back vehicle frame and buffer element.
Fig. 4 is the schematic side view of the utility model preferred embodiment.
Fig. 5 is a buffer element action scheme drawing in the utility model preferred embodiment.
In the preferred embodiment of the utility model buggy, a buffer element 36 can be installed at any wheel side, and reach the purpose of buffering and shock preventing, present embodiment is the example explanation with device in the back wheel location.
As Fig. 2, shown in 3, the buggy of tool elastic buffer of the present utility model effect, comprise a front vehicle frame 20, an one back vehicle frame 30 and a handle 40, before this, back vehicle frame 20, be provided with one group of trace 50 for 30 21, be provided with front vehicle wheel 21 at these front vehicle frame 20 ends, and above this front vehicle wheel 21, be provided with a stretcher 22, this back vehicle frame 30 is by a left side, right hack lever 31,32 link a union lever 33 that is inverted U forms, and on this left side, right hack lever 31,32 with union lever 33 bottom pivots have one group of wheel seat 34, cooperate shown in Figure 4, these wheel seat 34 1 sides are installed with a wheel shaft 341, for the rear wheel 35 that is pivoted, on this wheel seat 34, be provided with long slot bore 342 again, for this left side, right hack lever 31,32 wear knot with the end of union lever 33 is pivoted therebetween, in addition, on this left side, right hack lever 31,32 1 sides respectively are installed with a buffer element 36 (being to adopt a spring 361 in the present embodiment), and this wheel seat 34 1 sides and be provided with a mounting groove 343, the other end for this buffer element 36 embeds fixed, in addition, group is provided with a seat webbing 23 and a sun shade 24 on this front vehicle frame 20 and handle 40.
When the infant rides on this seat webbing 23, weight acts on this back vehicle frame 30, make this left side, right hack lever 31,32 to pressing down, because drawing of this spring 361 pulled, make this back vehicle frame 30 can support infant's weight, as shown in Figure 5, advance when carrying out hand barrow, when meeting road surface, pond, mountain peak or hand barrow collision foreign object, this rear wheel 35 is subjected to the external force effect to produce vertical tremor, to be passed to this wheel seat 34, long slot bore 342 a pivots knot left side because of this wheel seat 34, right hack lever 31,32, cause these wheel seat 34 meetings with respect to this left side, right hack lever 31,32 rotate, and make to be cemented in this left side, right hack lever 31,32 and the distortion that is stretched of the buffer element 36 (spring 361) of 34 of wheel seats, and sorption is in the vibrations of this rear wheel 35, so, can prevent that shaking force directly is passed to the infant who takes on this seat webbing 23, make the utility model can reach buffering effect, thereby prevent that the infant from being wounded.
