Abstract
The invention relates to the technical field of folding carts, in particular to a folding cart which can prevent accidental folding of a vehicle during pushing and pulling. The folding cart comprises a table-board supporting device, at least two folding table boards and locking mechanisms. Each folding table board at least comprises two supporting plate units which are connected in a pivoted mode. The supporting plate units are movably connected to the table-board supporting device. Each locking mechanism comprises at least two pivoted rods and at least one folding-resistant component. The pivoted rods are connected with each other and with the supporting plate units both in a pivoted mode. The folding-resistant components are connected with the pivoted rods in a pivoted mode. When the folding table boards are opened, the folding-resistant components are abutted against the pivoted rods to prevent the folding table boards from being folded. Compared with the prior, the folding cart has the advantages that the locking mechanisms can lock opening states of the supporting plate units firmly during pushing and pulling to prevent the folding cart from being folded accidentally, so that a person pushing the cart can be prevented from falling down due to the fact that the folding cart is folded accidentally, and potential safety hazards can be eliminated.

The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention in detail.
See also Fig. 1-4, folded bicycle of the present invention, comprise the mesa supports device, at least two folding table top and locking mechanisms, folding table top comprises two supporting plate unit 11 at least, two supporting plate unit of same folding table top pivot and connect, the supporting plate unit activity is connected in the mesa supports device, the table top that is formed for carrying under the supporting plate unit expansion lock-out state, locking mechanism comprises at least two pivoted poles 21 and at least one anti-foldable assembly 22, two pivoted poles 21 pivot and connect, and pivoted pole 21 pivots with the supporting plate unit and is connected, and anti-foldable assembly 22 pivots with two pivoted poles 21 and is connected, when folding table top was opened, it is folding to prevent folding table top that anti-foldable assembly 22 is tight against pivoted pole 21.
In this example, folding table top is 3, also can be two or more.Can in a side or the two sides of folded bicycle locking mechanism be set as required, when being equipped with locking mechanism on the two sides, can make that the open mode of folded bicycle is more firm, it is folding to be difficult for meeting accident, and can further improve security.
In this example, folded bicycle also comprises connecting rod 41, and connecting rod 41 pivots with supporting plate unit 11 and is connected, and the lower end of two pivoted poles 21 pivots with connecting rod 41 and is connected.Supporting plate unit 11 is provided with connecting hole, and the connecting hole on two supporting plate unit 11 of same folding table top connects by second rotating shaft, and connecting rod 41 pivots with second rotating shaft and is connected.By the synchronism that connecting rod 41 can improve the folding of each folding table top and open, make to fold the folding of table top and open more convenient.
As another kind of embodiment of the present invention, the lower end that 41, two pivoted poles 21 of connecting rod also can be set directly pivots with second rotating shaft and is connected.
See also Fig. 3,4, in this example, pivoted pole 21 is collapsible, and the two ends of anti-foldable assembly 22 are collapsible, and the two ends of anti-foldable assembly 22 pivot with the bending place of two pivoted poles 21 respectively and are connected.Particularly, pivoted pole 21 is divided into epimere 211 and hypomere 212 according to the position of open mode, and epimere 211 pivots by first rotating shaft with hypomere 212 and is connected, and the upper end of hypomere 212 is provided with the baffle plate 2121 for the rotational angle that limits epimere 211.When the epimere 211 of same pivoted pole and hypomere 212 formed approximate " one " font, baffle plate 2121 can block the lower end of epimere so that epimere can not be towards the direction bending of anti-foldable assembly, and it is folding to prevent folding table top to make anti-foldable assembly be tight against pivoted pole.The hypomere 212 of two pivoted poles pivots and connects.Anti-foldable assembly 22 is divided into left side section 221, spacing section 222 and right section 223 according to the position of open mode, pivoting with right section 223 with left side section 221 respectively for spacing section 222 is connected, and the other end of left side section 221 and right section 223 pivots with hypomere 212 with the epimere 211 of two pivoted poles by first rotating shaft respectively and is connected.
Epimere can be straight profiled bat or curved profiled bar, and in this example, epimere is curved profiled bar.Epimere is provided with reinforcement, can strengthen the intensity of epimere.
The mesa supports device comprises some legs 31, and in this example, leg 31 is 4, and each supporting plate unit pivots with leg and is connected, and each leg is arranged with universal wheel.
In the time will using folded bicycle, folded bicycle is holded up, press down spacing section 222, the supporting plate unit is opened, spacing section 222 function that can play handle, as shown in Figure 6.Continue to press down spacing section 222, stretch until pivoted pole, while left side section 221, spacing section 222 and approximate " one " font of right section 223 formation, at this moment, folded bicycle can use in opened condition, and it is folding to prevent folding table top that anti-foldable assembly is tight against pivoted pole, make that the supporting plate unit can be unexpected not folding, can improve safety in utilization.In the time will turning up folded bicycle, lift spacing section 222, left side section 221 and right section 223 relative limit sections 222 are turned up, simultaneously, make pivoted pole folding, the supporting plate unit is also turned up, and folded bicycle is folded state, can be convenient to deposit.
Folded bicycle of the present invention is in the push-and-pull process, and locking mechanism can firmly lock the open mode of supporting plate unit, and folded bicycle can unexpectedly not folded, and can avoid can eliminating safe hidden trouble owing to the unexpected folding phenomenon that causes the trammer to fall down of folded bicycle occurs.Spacing section of folded bicycle of the present invention also can be used as the handle use, makes things convenient for opening and turning up of folded bicycle.
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
