Technical Field

The invention relates to the technical field of children products, in particular to trolleys.

Background

The stroller is convenient for adults to carry small children for outdoor activities, and the stroller can be folded as usual, so that the stroller can be stably folded, and a folding locking mechanism is required to be arranged to lock the stroller in a folded state.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide improved trolleys.

In order to achieve the purpose, the invention adopts the technical scheme that:

kind of shallow has expansion and fold condition, the shallow includes the shallow frame, the shallow frame includes pole and second pole, pole with the second pole can relative motion, just pole with the second pole is in the shallow folding in-process is close to each other, the shallow still including be used for with the folding locking mechanism of shallow locking under fold condition, folding locking mechanism is including fixed the setting couple on pole with can set up with sliding the hanging post on the second pole, be provided with second cooperation portion and second cooperation portion on the couple respectively, be provided with on the hanging post respectively with third cooperation portion that cooperation portion cooperatees and with second cooperation portion complex fourth cooperation portion, work as the shallow is in the expansion condition, the couple is kept away from the hanging post, folding locking mechanism is in the unblock state, when the shallow is folding, the second pole with the second pole draw close to each other and make third cooperation portion with the cooperation of cooperation portion orders about the cooperation of hanging post relatively, the cooperation of second locking mechanism is in the cooperation of second locking mechanism, the folding locking mechanism cooperates with the fourth cooperation portion.

Preferably, the cooperation portion is the direction inclined plane that sets up in the tip of couple, the third cooperation portion is the spigot surface of hanging the post, when the spigot surface with the spigot surface is supported and is established, pole with the second pole draws close each other and makes the hanging post slide relatively the second pole.

, the guide surface is a chamfered surface provided at the end of the peg.

Preferably, the second engaging portion is a sliding groove formed in the hook, the fourth engaging portion is an end portion of the hanging post and engages with the sliding groove, and when the folding locking mechanism is in a locked state, the fourth engaging portion is snapped into the sliding groove.

, the chute is arcuate.

Preferably, the hook is located inside the th lever on the th lever, the hanging column is slidably provided on the second lever in a left-right direction of the cart, and the third engaging portion and the fourth engaging portion are both located inside the second lever on the hanging column.

Preferably, the folding locking mechanism further comprises an elastic member for urging the hanging post to return, and the elastic member is disposed between the hanging post and the second lever.

Preferably, the hanging column is further provided with a lifting part for pulling the hanging column during manual unlocking, and the lifting part is positioned on the hanging column and positioned on the outer side of the second rod.

Preferably, the cart frame includes fore-stock, after-poppet and push rod, the fore-stock with the after-poppet respectively with the push rod is connected mutually in rotating, the fore-stock be the th pole, push rod or the after-poppet be the second pole.

The invention also provides trolleys which have an unfolded state and a folded state, each trolley comprises a trolley frame, each trolley frame comprises a th rod and a second rod, each th rod and each second rod can move relatively, each th rod and each second rod are close to each other in the folding process of each trolley, each trolley further comprises a folding locking mechanism used for locking each trolley in the folded state, each trolley frame further comprises a third rod, each folding locking mechanism comprises a hook and a hanging column, each hook is fixedly arranged on the th rod, each third rod is rotatably connected with the corresponding second rod, a rotating shaft rotatably connected with the corresponding third rod is the corresponding hanging column, each hanging column can be slidably arranged relative to the corresponding second rod and the corresponding third rod, each hook is far away from the corresponding hanging column when each trolley is in the unfolded state, each folding locking mechanism is in the unlocked state, each hook is matched with the corresponding hanging column when each trolley is in the folded state, and each folding locking mechanism is in the locked state.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages: the cart disclosed by the invention is simple in structure, the hanging column is arranged on the second rod in a sliding manner, and the hanging column needs to slide relative to the second rod in the locking and unlocking processes of the folding locking structure. When the cart frames of the cart are mutually closed in the folding process, the hanging columns can be driven to slide relative to the second rods, so that the folding locking mechanism automatically moves, and after the cart is folded, the folding locking mechanism is automatically locked, manual operation is not needed, and the cart is convenient to operate and use.
