Description
Technical field
The utility model relates to a kind of children trolley, particularly a kind of folding children's barrow.
Background technology
Children trolley is used by increasing family, when needs transport children trolley or store, and usually need children trolley is folding to be convenient to transport and deposit to reduce volume.It is little that children trolley folding should satisfy when folding volume, and folding and opening operation makes things convenient for simultaneously.In the prior art, when folding children trolley was in released state, push rod and support normally broke away from fully, i.e. no any drive connection between push rod and the support causes folding or inconvenience when opening, comparatively requires great effort.
Summary of the invention
At the problems referred to above, the utility model provides a kind of children trolley, and its folding convenient is comparatively laborsaving.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of children trolley, comprise attaching parts, rotation is arranged on the front frame on the attaching parts, be arranged at the front component of front frame, be fixedly installed on the after poppet on the attaching parts, be arranged at the wheel assembly of after poppet, rotation is arranged on the push rod on the attaching parts, described children trolley also comprises a transmission device, this transmission device comprises first gear that is arranged on the front frame and second gear that is arranged on the push rod, described first gear is relative with second gear to be meshed, described children trolley comprises that also one is used for the locked lockout mechanism of relative first gear of second gear, in the lockout mechanism releasing process, described first gear and described second meshed transmission gear.
Preferably, described lockout mechanism comprise first locking block that is slidingly arranged in push rod and with described second gear fix setting second locking block, be arranged side by side at the 3rd gear on first gear, be arranged side by side the trailing cable that is used for driving described first locking block on second gear at the 4th gear and, be formed with first inclined-plane on described first locking block, be formed with second inclined-plane relative with first inclined-plane on described second locking block, when lock-out state, the 3rd gear is mutually stuck with the 4th gear; When released state, under the drive of trailing cable, second locking block can second inclined-plane with make the 4th gear the 3rd gear movement dorsad under first inclined-plane contacts.
More preferably, described lockout mechanism also comprises one for the retracing spring that described second locking block is resetted.
Preferably, described children trolley comprises that also one has the handle of unlock button, and described handle is connected rotationally with described push rod.
Preferably, the relative described attaching parts with described front frame of described push rod is finished gathering simultaneously.
Preferably, also be set with a folding hook for the children trolley locking that will be in the folding position on the described push rod.
The utility model adopts above structure, because in the lockout mechanism releasing process, the transmission that still is meshed of described first gear and described second gear makes push rod and front frame collapse to the after poppet place simultaneously; In addition, finish handle after the push rod gathering in the first step, push rod is owing to being subjected to the force of inertia that self gravitation and handle apply, push rod can be voluntarily or is only needed the user to apply minimum thrust can to realize drawing in to after poppet, the transmission because first gear and second gear still are meshed simultaneously, the power that push rod is received can be transferred to front frame, makes front frame be synchronized with push rod and draws in to after poppet voluntarily.Therefore, the utlity model has folding convenient, labour-saving advantage comparatively.

The specific embodiment
Below in conjunction with accompanying drawing content of the present utility model is elaborated with a kind of preferred embodiment.
Shown in accompanying drawing 1, accompanying drawing 2, a kind of children trolley, comprise attaching parts 1, rotate front frame 2, the front component 5 that is arranged at front frame be arranged on the attaching parts, be fixedly installed on after poppet 3 on the attaching parts, be arranged at after poppet wheel assembly 6, rotate the push rod 4 that is arranged on the attaching parts.
Described children trolley comprises that also one has the handle 7 of unlock button 71, and described handle 7 is connected rotationally with described push rod 4.Also be set with a folding hook 43 for the children trolley locking that will be in the folding position on the described push rod 4.
Shown in accompanying drawing 3, described push rod 4 is finished gathering simultaneously with described front frame 2 relative described attaching partss 1.After push rod 4 and front frame 2 collapsed to the after poppet place simultaneously, the folding hook 43 on the push rod 4 was stuck on the after poppet 3, thereby will be in the children trolley locking of folding position.Go-cart after folding still can be stablized and stood on the ground.
Shown in accompanying drawing 4-6, described children trolley also comprises a transmission device, this transmission device comprises first gear 21 and second gear 41 that is arranged on the push rod 4 that is arranged on the front frame 2, described first gear 21 and the 41 relative engagements of second gear, described children trolley comprises that also one is used for the locked lockout mechanism of relative first gear 21 of second gear 41, in the lockout mechanism releasing process, described first gear 21 and described second gear, 41 engaged transmission.
Described lockout mechanism comprise first locking block 11 that is slidingly arranged on the push rod 4 and with described second gear 41 fix setting second locking block 12, be arranged side by side at the 3rd gear 22 on first gear 21, be arranged side by side the trailing cable that is used for driving described first locking block 11 on second gear 41 at the 4th gear 42 and, be formed with first inclined-plane 111 on described first locking block 11, be formed with second inclined-plane 121 relative with first inclined-plane 111 on described second locking block 12, when lock-out state, the 3rd gear 22 is mutually stuck with the 4th gear 42; When released state, under the drive of trailing cable, second locking block 12 can second inclined-plane 121 with make the 3rd gear 22 motions dorsad of the 4th gear 42 under first inclined-plane 111 contacts, the 4th gear 42 and the 3rd gear 22 are separated, and since the facewidth of second gear 41 and first gear 21 much larger than the facewidth of the 4th gear 42 and the 3rd gear 22, therefore under released state, the transmission that still is meshed of second gear 41 and first gear 21.
Described lockout mechanism also comprises one for the retracing spring 13 that described second locking block 12 is resetted.When the vehicle frame of go-cart is opened to certain position, the thrust that retracing spring 13 deformation produce promotes second locking block 12 towards 11 motions of first locking block, second locking block 12 can second inclined-plane 121 with make under first inclined-plane 111 contacts the 4th gear 42 towards 22 motions of the 3rd gear, the 4th gear 42 is mutually stuck with the 3rd gear 22.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics; it is a kind of preferred embodiment; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed within the protection domain of the present utility model.
