Detailed Description

The present invention will be described in further detail with reference to the following examples:

a folding handcart is shown in figures 1-5 and comprises a frame, a handcart body 12 fixedly arranged on the frame, a front wheel 13 and a rear wheel 8 which are arranged below the frame, wherein the front wheel 13 and the rear wheel 8 rotate to drive the frame to walk on the ground, the handcart body 12 is fixedly arranged in the frame and is made of canvas materials, various articles can be placed in the handcart body 12, and a user can take the handcart conveniently.

As shown in fig. 1 and 2, the frame comprises four vertical rods 4 fixedly arranged between the base and the top seat 2 and a folding structure connected with the vertical rods 4, and after use, the frame can be folded for storage, which is beneficial to storage.

As shown in fig. 2, the folding structure includes a bottom folding unit, two width folding units which are connected with the bottom folding unit through a base and symmetrically arranged, and two length folding units which are connected with the width folding units through a top base 2 and symmetrically arranged.

As shown in fig. 2 and 3, the bottom folding unit includes four bottom rods 17 rotatably connected to the connecting body 16, and the other ends of the bottom rods 17 are rotatably connected to the base. As shown in fig. 4, a lifting block 16-2 and a connecting block 16-1 integrally arranged with the connecting body 16 are arranged on the back of the connecting body 16, the connecting block 16-1 is connected with a bottom rod 17 through a rotating rod 19, and the other end of the bottom rod 17 is rotatably connected with a base. When the foldable storage is needed, the lifting block 16-2 is lifted, the connecting block 16-1 drives the bottom rods 17 to move upwards along with the lifting block 16-2, the four bottom rods 17 are erected on the outer side of the lifting block 16-2, and bottom folding is completed as shown in fig. 5; when the folding type foldable bicycle is required to be unfolded for use, the bottom rod 17 moves outwards and downwards from the vertical state until the bottom rod is horizontally unfolded as long as the connecting body 16 is pressed downwards.

As shown in fig. 2, the length folding unit comprises two side bars 18 connected by a rotating shaft 15, the other ends of the side bars 18 are rotatably connected with the top seat 2, when the folding storage is needed, the rotating shaft 15 drives the side bars 18 at two sides to move upwards, and the side bars 18 at two sides are vertically folded together; when the folding bicycle needs to be unfolded for use, the side rods 18 on the two sides are pulled downwards, and the side rods 18 drive the rotating shaft 15 to move downwards until the folding bicycle is unfolded.

The supporting rod 10 is arranged between the side rod 18 and the vertical rod 4, and the supporting rod 10 plays a role of supporting the side rod 18 and can ensure that the side rod 18 is unfolded in an unfolding state. The supporting rod 10 comprises a second rod 10-2 fixedly connected with a side rod 18 and a first rod 10-1 fixedly connected with the vertical rod 4, wherein a hole is formed in the first rod 10-1, and the hole is matched with a protrusion arranged on the second rod 10-2. When the folding is needed, the bulge and the hole are separated, so that the first rod 10-1 is separated from the second rod 10-2, and then the rotating shaft 15 is lifted upwards to complete the folding; after deployment is complete, the projections and holes are engaged so that the brace 10 supports the side poles 18 for full deployment, as shown in figure 2.

As shown in fig. 2, the width folding unit includes two slant bars 5 rotatably connected and a cross bar 11 connected to the top ends of the slant bars 5 through a rotating shaft 15, the other end of the cross bar 11 is rotatably connected to the top base 2, and the bottom ends of the slant bars 5 are rotatably connected to the base. When needing to be folded, upwards mention pivot 15, pivot 15 drives horizontal pole 11 and down tube 5 rebound simultaneously, until two down tubes 5, two horizontal poles 11 are folded together completely, when needing to expand, outwards drags horizontal pole 11 and down tube 15 simultaneous pivot 15 rebound until horizontal pole 11 becomes the horizontal body, and the slope of down tube 15 sets up and expandes completely.

In the using process, when the folding bicycle needs to be folded, the first rod 10-1 and the second rod 10-2 of the supporting rod 10 are separated firstly, the connecting body 16 is lifted upwards, then the vertical rods 4 on the two sides drive the wheels to be folded inwards until the vertical rods 4, the side rods 18, the inclined rods 5 and the bottom rod 17 are completely and vertically stood together, all folding structures are completely folded, and the volume after folding is the minimum. The folded product is only 70 cm high and about 50 cm in diameter, is easier to store and carry compared with the unfolded state, and then is put into a bag or directly put into a trunk of the vehicle; when in use, the connecting body 16 is taken out, the connecting body is pressed downwards, then the vertical rods 4 at two sides are pulled outwards, the wheels are unfolded outwards along with the vertical rods 4, and finally the first rod 10-1 and the second rod 10-2 are completely matched to support the side rod 18 as shown in figure 2.

As shown in fig. 1 and 2, the base includes a first base 6 and a second base 14, the first base 6 is connected to a rear wheel 8 provided with a brake 7, and the second base 14 is connected to a front wheel 13. The arrangement of the brake 7 can avoid the danger caused by the over-high speed of the vehicle when going downhill.

The second base 14 is rotatably connected with the push handle, so that the height of the push handle can be adjusted up and down as required, when the push handle is higher, the push handle is integrally rotated upwards, and when the push handle is lower, the push handle is integrally rotated downwards.

The push handle comprises a connecting part 1 with a long hole in the center, a connecting rod 3 with the end part fixedly connected with the connecting part 1 and a pull handle 9-1 matched and connected with the long hole, the length of the pull handle 9-1 can be adjusted according to the length of the pull handle 9-1 penetrating through the connecting part 1, the longer the pull handle 9-1 penetrates through the connecting part 1, the shorter the push handle, the shorter the pull handle 9-1 penetrates through the connecting part 1, and the longer the push handle 9-1, and the adjustment can be carried out according to the needs in the use process. The other end of connecting rod 3 rotates with second base 14 and is connected, when connecting rod 3 upwards rotates around second base 14, pushes away the handle and is increaseed, when connecting rod 3 down rotates around second base 14, pushes away the handle and is increaseed, and the use can as required adjustment.

As shown in fig. 1 and 2, the handle 9-1 is provided with a handle 9 at the end, and the handle 9 is arranged to provide a convenient grip for both hands.

Finally, it should be noted that: the above examples are merely illustrative for clearly illustrating the present invention and are in no way to be construed as limiting the embodiments. It will be apparent to those skilled in the art that many more modifications and variations than mentioned above are possible in light of the above teaching, and it is not intended to be exhaustive or to limit all embodiments to the precise form disclosed, and all changes and modifications that are obvious are intended to fall within the scope of the utility model.
