Preferably, the wall body of adapter sleeve has helical pitch groove, and this helical pitch groove extends along the direction of slip of pole, and accordingly, the outer wall of pole is protruding with the projection, this projection and the helical pitch groove bearing fit that insert helical pitch groove.
Preferably, the upper end of pillar is set with jump ring, and this jump ring compresses mutually with the inwall of adapter sleeve, and the end of jump ring is by protruding in the wall body of adapter sleeve.
Preferably, push rod is provided with unlock switch, is provided with the lockout mechanism with unlock switch linkage of unlocking in sliding sleeve, this lockout mechanism is for locking sliding sleeve and back leg bar.
Preferably, back leg bar is provided with the first stop gear for limiting sliding sleeve sliding stroke.
Preferably, push rod is provided with the second stop gear of the sliding stroke for limiting adapter sleeve.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is after push rod and tarpaulin rod are turned folding relative to back leg bar by the effect of rotation section, lower sustentacula can also be passed through, sliding sleeve is glided along back leg bar, thus make corresponding push rod, tarpaulin rod moves down, everybody gathers to make each rod member, to realize the twice-folded of go-cart, and can reduce the size after folding further, facilitate packed and transported, reduce traffic cost.

In figure: 1, push rod; 2, tarpaulin rod; 3, adapter sleeve; 31, helical pitch groove; 4, pole; 5, sliding sleeve; 51, rotation section; 6, back leg bar; 7, jump ring; 8, unlock switch.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Go-cart twice-folded mechanism as shown in figures 1-4, comprise push rod 1, tarpaulin rod 2, adapter sleeve 3, pole 4, sliding sleeve 5 and back leg bar 6, sliding sleeve 5 slip cap is loaded on back leg bar 6, and the sidepiece of this sliding sleeve 5 is hinged with a rotation section 51, the lower end of push rod 1 and the lower end separation of pole 4 are plugged in this rotation section 51, the upper end of pole 4 is plugged in this adapter sleeve 3 by the lower end of adapter sleeve 3, and this pole 4 and adapter sleeve 3 bearing fit, the lower end of tarpaulin rod 2 is plugged in adapter sleeve 3 by the upper end of adapter sleeve 3.
At push rod 1 and tarpaulin rod 2 by the effect of rotation section 51 after turning folding relative to back leg bar 6, lower sustentacula can also be passed through, sliding sleeve 5 is glided along back leg bar 6, thus make corresponding push rod 1, tarpaulin rod 2 moves down, everybody gathers to make each rod member, to realize the twice-folded of go-cart, and the size after folding can be reduced further.Wherein, when pole 4 is drop-down, move down under the guiding of adapter sleeve 3.Particularly, use when sliding sleeve 5 is normal folding in stroller frame use procedure, adapter sleeve 3 is by folding further after carriage wheel dismounting, makes it box volume less.
Mutually depart from for preventing adapter sleeve 3 and pole 4, the wall body of adapter sleeve 3 has helical pitch groove 31, this helical pitch groove 31 extends along the direction of slip of pole 4, accordingly, the outer wall of pole 4 is protruding with the protruding (not shown) inserting helical pitch groove 31, this projection and helical pitch groove 31 bearing fit, protruding being limited in is slided in helical pitch groove 31, thus limits the sliding stroke of pole 4 relative to adapter sleeve 3.
There is provided more stable connection to coordinate when launching for making go-cart, the upper end of pillar is set with jump ring 7, and this jump ring 7 compresses mutually with the inwall of adapter sleeve 3, and the end of jump ring 7 is by protruding in the wall body of adapter sleeve 3.When go-cart launches, by the banding elastic force effect of jump ring 7, pole 4 will be fastened onto in adapter sleeve 3; When go-cart twice-folded, pressing jump ring 7 end make jump ring 7 remove banding elastic force after, pole 4 can in adapter sleeve 3 free-extension.
Obtain more stable connection when launching for making go-cart further to coordinate, push rod 1 is provided with unlock switch 8, is provided with and the lockout mechanism of unlock switch 8 linkage of unlocking (shown in figure) in sliding sleeve 5, this lockout mechanism is for locking sliding sleeve 5 and back leg bar 6.When go-cart launches, by the locking effect of lockout mechanism, sliding sleeve 5 and back leg bar 6 will be locked, and when go-cart twice-folded, after being unlocked by pressing switch 8, unclamp the coupling mechanism force of lockout mechanism, now sliding sleeve 5 can be free to slide relative to back leg bar 6.
Be understandable that, lockout mechanism can adopt elasticity protruding pin to be connected to unlock switch 8 by transmission device, realizes the unlock drive power transmission of unlock switch 8.
Fig. 4 shows this go-cart twice-folded mechanism and installs the situation be applied in go-cart.
Back leg bar 6 is provided with the first stop gear (not shown) for limiting sliding sleeve 5 sliding stroke, by the restriction of the first stop gear, make sliding sleeve 5 form confined stroke between the paulin seat of adapter sleeve 3 and go-cart, during twice-folded, adapter sleeve 3 moves towards paulin seat direction.
Push rod 1 is provided with the second stop gear (not shown) of the sliding stroke for limiting adapter sleeve 3, thus is limited in certain action radius by adapter sleeve 3.
First stop gear and the second stop gear can adopt the conventional equipments such as snap close, baffle plate, spring pin to realize.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
