Specific embodiment
This example provide it is a kind of can horizontal folding bracket assembly and the go-cart for double child comprising the bracket assembly.Branch Support component includes support frame and locking mechanism.
As shown in Figures 1 to 3, which show the structure of support frame.Support frame includes being located at the side pole 1 of both sides, is located at Middle support rod 2 between the side pole 1 of both sides, it is successively set on from top to bottom on middle support rod 2 and along the length of middle support rod 2 The first sliding part 3 that degree direction can be slided, the second sliding part 4 and slide foot-operated 5, one end respectively with the first sliding part 3 First singletree 6 and the second singletree 7 of connection are rotated relative to two sides, one end turns with relative two side for sliding step 5 respectively 3rd singletree 8 and the 4th singletree 9 of dynamic connection, upper end rotate what is connected with relative two sides of the second sliding part 4 respectively First hound 10 and the second hound 11, the connecting rod 23 that upper and lower end parts are connected with the first sliding part 3 and slip step 5 respectively, Connecting rod 23, the first sliding part 3 and slide step 5 can be wholely set, also can any two be wholely set or three independently Set, the first singletree 6, the second singletree 7, the 3rd singletree 8, the 4th singletree 9 the other end respectively with the side of homonymy Pole 1 rotate connection, the first hound 10, the second hound 11 bottom respectively with the 3rd singletree 8 and the 4th singletree 9 Rotate connection, the part of the described connection that rotates is rotated connection by pivot, these pivot axis parallels and along level side To extension.The sliding part 4 of first sliding part 3 and second is sliding sleeve, is set on middle support rod 2.
During folding, after locking mechanism is unlocked, provoked upwards with pin by step 5 is slided, the first sliding part 3, second is slided Part 4 and slide the overall upward sliding on middle support rod 2 of step 5, each singletree and hound around respective turning point rotate to Middle support rod 2 is drawn close and drives side pole 1 to be drawn close to centre, and to state shown in Fig. 3, folding operation is very convenient.The support frame Component is particularly suitable for go-cart for double child.
As shown in Fig. 4 to 8, which show the structure of go-cart for double child.Go-cart for double child includes having expansion shape The trolley rack of state and folded state, front component 12, wheel assembly 13, trolley rack are included positioned at side stand, the position of the side of go-cart two Intermediate support in the middle of go-cart, positioned at go-cart rear portion can horizontal folding back pole-bracket and for trolley rack to be locked in into expansion The locking mechanism of state.Side stand is provided with the trailing wheel including the front-wheel support 14, bottom that bottom is provided with the front component 12 The rear wheel support 15 and handle 16 of component 13, intermediate support include the upper end connection of fore-stock 17, upper end and fore-stock 17 After-poppet 18.The rear wheel support 15 of both sides, the combination of after-poppet 18 and back pole-bracket is support frame described above, trailing wheel Support 15, after-poppet 18 corresponds to side pole 1 and the middle support rod 2 of support frame respectively, and back pole-bracket corresponds to its remaining part of support frame Point, it is not described in detail herein.
In this example, locking mechanism is included for preventing the locking device of the upward sliding of the first sliding part 3, being arranged on after-poppet It is used to prevent the locating part 19 and the tripper for unlocking locking device of the slide downward of the second sliding part 4 on 18, it is sliding The escape groove for avoiding locating part 19 is offered in dynamic step 5, therefore, locating part 19 can be passed freely through.Locating part 19 is specially one Spacer pin.
Specifically, locking device includes the lockhole 20 being opened on after-poppet 18, is slided along the centerline direction of lockhole 20 The dead bolt 21 that sets dynamicly, it is arranged between dead bolt 21 and after-poppet 18 and is used to make what dead bolt 21 was moved towards the direction of lockhole 20 Elastic component(Do not shown in figure), when trolley rack is in deployed condition, locking device is in the lock state, and dead bolt 21 passes through lockhole 20 and its following side offseted with the upper lateral part of the first sliding part 3.The following side of the second sliding part 4 is against on locating part 19, the One hound 10, between the 3rd singletree 8 and after-poppet 18, the second hound 11, between the 4th singletree 9 and after-poppet 18 point Stable triangular structure of right angle is not constituted.
Specifically, tripper includes being arranged on handle 22 on the upper end of after-poppet 18, two ends respectively with handle 22 The hauling rope being connected with dead bolt 21(Do not shown in figure).
Additionally, handle 24 is additionally provided with the upper end of after-poppet 18, in order to operate.
In this example, the setting of the miscellaneous part of go-cart for double child is this area conventional arrangement mode, no longer detailed herein State.
The unfolding mode of the go-cart of the present embodiment is as follows:Handle 24 is pulled, step 5 will be slided and stepped on downwards, the first sliding part 3 With the entirety of the second sliding part 4 along the slide downward of after-poppet 18, while four singletrees are propped up, rear wheel support 15 is supportted and is propped up backward The both sides of frame 18, when the first sliding part 3 slips over lockhole 20, dead bolt 21 is ejected, and is kept off in the upside of the first sliding part 3, now, the One sliding part 3 can not upward sliding;At the same time, the second sliding part 4 reach locating part 19 position cannot slide downward, this When, the distance between turning point on the second sliding part 4 and the turning point slided in step 5 no longer change, and constitute two stabilizations Rigid right angled triangle, trolley rack be locked, in opened condition, as shown in Figure 5.
The folding mode of the stroller of the present embodiment is as follows:Handle 22 is pulled, is made in the body of the retraction after-poppet 18 of dead bolt 21, Provoked step 5 is slided upwards with pin, the first sliding part 3, the second sliding part 4 and slip step 5 slide up on after-poppet 18 Dynamic, all singletrees and hound are rotated around respective turning point to be drawn close to after-poppet 18 and drives rear wheel support 15 to be leaned on to centre Hold together, in folded state, as shown in Figure 8.
As described above, go-cart for double child of the invention is not only simple in structure, and folding and opening operation are very convenient.
The present invention is described in detail above, its object is to allow the personage for being familiar with this art to will appreciate that this The content of invention is simultaneously carried out, and it is not intended to limit the scope of the present invention, all Spirit Essence institutes according to the present invention The equivalent change or modification of work, should all cover within the scope of the present invention.
