Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a foldable handcart as shown in fig. 1-4, including two bridging mechanism 1, mount pad 7 and supporting platform 10, two bridging mechanism 1 all include first lapping plate 101 and second lapping plate 102, one side of first lapping plate 101 is passed through hinge 3 cooperation screw and is connected with second lapping plate 102 rotation, two universal wheels 2 are installed to the bottom of first lapping plate 101, the wheel cover that silica gel material made has been cup jointed on the surface of universal wheel 2, increase the ground effect of grabbing of universal wheel 2 with this, avoid taking place the skew of position easily in the shallow use.

The surface of the first lapping plate 101 is provided with two first limiting grooves 4, the surface of the second lapping plate 102 is provided with a second limiting groove 5, the surface of one side of the first lapping plate 101 is provided with a mounting hole 6, two mounting seats 7 are respectively fixed on the surface of one side of the two first lapping plates 101 through bolt matching mounting holes 6, the two mounting seats 7 are connected with a connecting rod 8 through keys, and a pull rod 9 is welded between the two connecting rods 8; the connecting rod 8 and the pull rod 9 are of an integrated structure made of steel structure materials, have good strength and rigidity, and have sufficient supporting effect for pushing and pulling the trolley; and the surface of the pull rod 9 is sleeved with an anti-slip sleeve made of rubber materials, and the anti-slip sleeve is provided with anti-slip lines, so that the surface friction force of the pull rod 9 is increased, and the operation of workers is facilitated.

Four first limiting blocks 11 and two second limiting blocks 12 are sequentially arranged on one side surface of the supporting platform 10, reinforcing ribs 13 are sequentially and uniformly arranged on one side surface of the supporting platform 10, the supporting platform 10 is sequentially fixed with four first limiting grooves 4 arranged on two first lapping plates 101 in an inserting manner through the four first limiting blocks 11, and the two second limiting blocks 12 are respectively fixed with second limiting grooves 5 arranged on two second lapping plates 102 in an inserting manner; all be equipped with anti-skidding line on the inner wall of first spacing groove 4 and second spacing groove 5, and the rubber pad has all been cup jointed on the surface of first stopper 11 and second stopper 12, can increase the frictional force between first stopper 11, second stopper 12 and first spacing groove 4, the second spacing groove 5 with this, improve the contact effect, increase grafting stability.

An open slot 14 is formed between the bottom surface of the supporting platform 10 and the top surfaces of the two lap joint mechanisms 1, a certain gap is reserved, so that the position relation between the hinge 3 and the first lap joint plate 101 and the second lap joint plate 102 is ensured, and the folding effect is prevented from being influenced by the overlarge pressure bearing area of the two lap joint mechanisms 1.
