[0028] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.
[0029] Embodiment 1: Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, A folding bike, comprising a tabletop support device and at least two folding tabletops arranged on the tabletop support device. The folding tabletop includes two pallet units 11 of the same folding tabletop and a pivot connection mechanism 12 for unfolding and folding the two pallet units 11 of the same folding tabletop. The pallet unit 11 is arranged on the tabletop support device, and a locking structure 13 is arranged on the uppermost folding tabletop. A handle mechanism 14 for folding is arranged on the uppermost pivot connection mechanism 12. First, open the locking structure 13, and then lift it forcefully through the handle mechanism 14. At this time, the two pallet units 11 of the same folding tabletop are folded with the pivot connection mechanism 12 as the fulcrum. When the handle mechanism 14 is pushed forcefully, the two pallet units 11 of the same folding tabletop are unfolded with the pivot connection mechanism 12 as the fulcrum. In this example, there are three folding tabletops, which can also be two or more. The locking structure 13 can be arranged on one side or both sides of the folding bike as needed. When the locking structure 13 is arranged on both sides, the open state of the folding bike can be made more firm, and accidental folding is not likely to occur, which can further improve safety.
[0030] Embodiment 2: It can be described based on Embodiment 1. For example, Figure 2 , Figure 4 and Figure 5 As shown, the pivot connection mechanism 12 includes a pivot rod 121 arranged between the two pallet units 11. A base 122 for fixed connection is arranged on the two pallet units 11. The pivot rod 121 passes through the base 122. This kind of setting is simple and easy to implement, and can realize the folding and unfolding movement of the two pallet units 11 of the same folding tabletop with the pivot rod 121. It should be noted that a through hole for the pivot rod 121 to pass through is opened on the base 122, and the base 122 and the corresponding two pallet units 11 are integrally formed, reducing the difficulty of production and manufacturing.
[0031] Embodiment 3: It can be described based on Embodiment 2. For example, Figure 3As shown in the figure, the handle mechanism 14 includes a mounting groove 141 provided on the upper surface of two pallet units 11. The pivot rod 121 is provided with a pair of distributed mounting seats 142. Each mounting seat 142 is provided with two rotating shafts. A handle 143 is provided between the two rotating shafts, and the handle 143 can be placed downward in the mounting groove 141 with the rotating shaft as the fulcrum. In this way, the handle 143 will not occupy the space of the folding tabletop. When the two handles 143 are flipped upward and then the handles 143 are lifted, the two pallet units 11 on the same folding tabletop are folded with the pivot connection mechanism 12 as the fulcrum. When the handle 143 is pushed forcefully, the two pallet units 11 on the same folding tabletop are unfolded (opened) with the pivot connection mechanism 12 as the fulcrum. By operating the handle 143, the open state and the folded state of the folding cart can be realized.
[0032] Embodiment 4: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3. As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown in the figure, the tabletop support device includes a support rod 21 passing through two pallet units 11 of the same folding tabletop. The support rods 21 are correspondingly distributed on both sides of the pallet unit 11, and the two support rods 21 in the width direction of the pallet unit 11 are connected into one body by an armrest rod 22. A universal roller 23 is provided on the lower end surface of the support rod 21. This kind of setting is reasonable and easy to implement. It is more convenient to move through the universal roller 23.
[0033] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown in the figure, the pivot connection mechanisms 12 between the two pallet units 11 in each layer are connected by a fixing rod 24. The fixing rod 24 is distributed in parallel with the support rod 21, and a slider 25 moving along the length direction of the fixing rod 24 is provided on the fixing rod 24. The left and right sides of the slider 25 are respectively pivotally connected with a connecting rod one 26 and a connecting rod two 27. The other sides of the connecting rod one 26 and the connecting rod two 27 are respectively pivotally connected to the folding tabletop at the lower position under the uppermost folding tabletop. This kind of setting is beneficial to better realize the folding and opening states of the folding cart.
[0034] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4. As Figure 4 、 Figure 5 and Figure 6As shown, the locking structure 13 includes a fixed shaft 131 disposed on a pallet unit 11 on the topmost folding tabletop and a clamping shaft 132 disposed on another pallet unit 11. A lock plate 133 capable of rotating back and forth is disposed on the fixed shaft 131. A clamping groove 134 for cooperating with the clamping shaft 132 is disposed on the lock plate 133. When in use, after the lock plate 133 rotates towards the clamping shaft 132, the clamping groove 134 is clamped with the clamping shaft 132. At this time, the two pallet units 11 on the folding tabletop are in an open and flattened state and are fixed. When the folding cart needs to be folded, first, the lock plate 133 needs to be flipped upwards to open, that is, the clamping groove 134 is disengaged from the clamping shaft 132, and then lifted forcefully through the handle mechanism 14. At this time, the two pallet units 11 on the same folding tabletop are folded with the pivot connection mechanism 12 as the fulcrum.
[0035] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts and rivets that are mature in the prior art, and no specific description will be made here.
[0036] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, the changes and modifications made to the embodiments described in this article, or the equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
