The specific embodiment

As shown in Figure 1 and Figure 2, present embodiment is usher to seat pocket or the folding children trolley of sleeping basket, and rod member is less, and volume after folding is little.Specifically being provided with of this children trolley is as follows:

Children trolley comprises go-cart vehicle frame with deployed condition and folded state, be used for the go-cart vehicle frame be locked in deployed condition the expansion lockout mechanism, be used for the go-cart vehicle frame is locked in fold locking mechanisms, front-wheel 1 and the trailing wheel 2 of lock-out state, the go-cart vehicle frame comprises front-wheel support 10, at the rear wheel support 20 of the symmetrical setting in both sides, the hind axle 21 that connects both sides trailing wheel 2, and rotate bonded assembly pulling handle rod 3 and be arranged on the grafting bar 4 that is used for graft block pocket or sleeping basket between the upper end of two rear wheel supports 20 of rear wheel support 20 upper ends.

Pulling handle rod 3 is a telescopic tube, comprises push-down handle bar 31 and is plugged in push-up handle bar 32 in the push-down handle bar 31 slidably, and the length of pulling handle rod 3 can be regulated according to different human needs.The bottom internal fixation of push-down handle bar 31 is inserted with tumbler 30, this tumbler 30 be fixedly installed on rear wheel support 20 on first attaching parts 22 between rotate by turning cylinder 8 and to be connected; The end of grafting bar 4 is set with second attaching parts 41, and this second attaching parts 41 also rotates with first attaching parts 22 by turning cylinder 8 and is connected.The bottom of the described rear wheel support 20 in both sides rotates with the both ends of hind axle 21 respectively and is connected, front-wheel support 10 is horizontally disposed with along fore-and-aft direction, be provided with two front-wheels 1 at its leading section symmetrically by front-wheel connector 5, the middle part of end and hind axle 21 is fixedly connected thereafter; Its length direction has been mounted slidably cliding seat 6 in front-wheel support 10 upper edges, and this cliding seat 6 is provided with rotationally to be used to support the U-shaped bottom supporting rod 7 of rear wheel support 20, and two upper ends of this U-shaped bottom supporting rod 7 rotate with rear wheel support 20 and are connected.

Described expansion lockout mechanism comprises and is used for first blocking device of push-down handle bar 31 and rear wheel support 20 relative lockings and is used for second blocking device of cliding seat 6 with front-wheel support 10 relative lockings.As shown in Figure 7 and Figure 8, first blocking device comprises the exterior bayonet slot 300 that is opened on the tumbler 30, be opened in inner card cage 220 on first attaching parts 22, be arranged between exterior bayonet slot 300 and the inner card cage 220 along the locking block 9 that axially slidably is provided with of turning cylinder 8 and be arranged on first spring 40 between push-down handle bar 31 bottoms and the locking block 9, when first blocking device was in the lock state, locking block 9 all fastened with exterior bayonet slot 300 and inner card cage 220; When first lockout mechanism was in released state, locking block 9 broke away from inner card cages 220, and this moment, push-down handle bar 31 can rotate relative to rear wheel support 20 moving axis 8 that rotates.Be provided with to have on trip lever 33 locking blocks 9 that can slide along its length direction for what inserted the bottom 330 of trip lever 33 in push-down handle bar 31 and separate locked groove 91, this bottom of separating locked groove 91 has from top to bottom by push-down handle bar 31 to rear wheel support 20 bevelled inclined-planes 92.So, it is downward to promote push-up handle bar 32, and when pressing down trip lever 33, trip lever 33 will act on the inclined-plane 92, and promotes locking block 9 towards the direction motion that breaks away from inner card cage 220, thus, first blocking device is converted into released state from lock-out state.

Offer the axially extended coordination groove 410 along turning cylinder 8 on the second above-mentioned attaching parts 41, locking block 9 has the salient 90 that matches with this coordination groove 410, and this salient 90 can be provided with slidably along coordination groove 410.So, then when rotating push-down handle bar 31, tumbler 30 drives second attaching parts 41 by locking block 9 and rotates.

As Fig. 9 and shown in Figure 10, second blocking device comprises lock slots 60 that is opened on the cliding seat 6 and the locking bar with latch hook 420 42 that is arranged on the front-wheel support 10, when second blocking device is in the lock state, latch hook 420 is hooked in the lock slots 60, when being in released state, latch hook 420 breaks away from described lock slots 60.

Locking bar 42 rotates with front-wheel support 10 at the middle part and is connected, and also link to each other between described locking bar 42 and the front-wheel support 10 by torsion spring 12, be connected with an end of trailing cable 43 on the end relative with latch hook 420 of locking bar 42, the other end of trailing cable 43 is connected with unlock button 44 on being arranged on the go-cart vehicle frame.Handle unlock button 44 pulling trailing cables 43, second blocking device is carried out release.

On first attaching parts 22, offer the button groove 221 that holds unlock button 44, unlock button 44 can be arranged on herein.Between the described unlock button 44 and first attaching parts 22, be provided with second spring 45, when 44 pairs second blocking devices of promotion unlock button carry out release, second spring 45 is compressed, and then after the power releasing that is applied on the unlock button 44, resets under the effect of second spring 45.

Be provided with gas spring 46 between front-wheel support 10 and cliding seat 6, the leading section of this gas spring 46 links to each other with front-wheel support 10, and rearward end links to each other with cliding seat 6.

The folding operation of children trolley carries out according to the following steps:

Push-up handle bar 32 downward telescopic slide at first, when push-up handle bar 32 slides into bottom, promote locking block 9 and slide, first blocking device is carried out release, at this moment, push-down handle bar 31, locking block 9 and second attaching parts 41 moving axis that can rotate is swung down to position shown in Figure 5.At this moment, press 44 pairs second blocking devices of unlock button and carry out release, press tumbler 30 simultaneously downwards, driving rear wheel support 20 and U-shaped bottom supporting rod 7 simultaneously forwards rotates, cliding seat 6 slides on front-wheel support 10, gas spring 46 is compressed, and finally reaches folded state shown in Figure 6, and pin go-cart by the fold locking mechanisms that is arranged on the go-cart vehicle frame this moment.In this example, U-shaped ground strut 7 is provided with has hook 13, hangs over realization locking on any rod member by linking up with 13.

For the go-cart of folded state, only need pull hook 13, remove folding locking, then under the effect of gas spring 46, go-cart is opened to state shown in Figure 5 automatically, and pull-up this moment pulling handle rod 3 can make go-cart reach deployed condition.

In sum, children trolley of the present utility model does not have rod member when folding and opening interferes, and easy and simple to handle, folding volume is little.
