Description

Technical Field

[0001] The utility model relates to the technical field of trolleys, in particular to a mobile folding trolley. Background Art

[0002] A trolley is a transport vehicle that is pushed and pulled by manpower. Usually, pulleys are arranged at the four corners of the lower end of the trolley plate, and the trolley plate is moved with the help of the pulleys. The existing method of taking a pet out is nothing more than a traction rope or the pet owner holding it manually. However, for large pets, it is more laborious to hold them manually and it is inconvenient to walk. If the pet is placed on a trolley, the large pet can be directly moved, which is more labor-saving and convenient than manual operation.

[0003] At present, since the size of the trolley is fixed in an assembled manner, such a setting causes the user to occupy a large space when storing and placing the trolley. At the same time, when the trolley needs to be carried, the trolley is fixed in a certain space, which causes inconvenience in carrying.

[0004] So we propose a mobile folding trolley to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a mobile foldable trolley to solve the problem that the size of the trolley is fixed in an assembled manner, which causes the user to occupy more space when storing the trolley. At the same time, when the trolley needs to be carried, the fixed space is limited, which leads to inconvenience in carrying.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mobile folding trolley, comprising a vehicle floor and first sliding wheels respectively fixedly installed at two ends of one side of the lower end of the vehicle floor, brackets are fixedly installed at two ends of the other side of the lower end of the vehicle floor, and second sliding wheels are respectively arranged at two ends of the brackets, rear support assemblies are respectively fixedly installed at two ends of one side of the upper end of the vehicle floor, main connecting assemblies are respectively movably installed in the middle of both sides of the outer wall of the vehicle floor, and a driven assembly is movably installed on one side of the upper end of the rear support assembly.

[0007] Preferably, the rear support assembly includes a concave bracket and a first U-shaped round rod movably mounted via a movable shaft, a second U-shaped round rod movably mounted on one side of the inner wall of the concave bracket, and first inner screw groove rods are fixedly mounted on both sides of one side of the lower end of the second U-shaped round rod.

[0008] Preferably, on both sides of the middle part of the outer wall of the first U-shaped round rod, hinge blocks are respectively and fixedly installed. On one side of the hinge block, a third U-shaped round rod is movably installed. In the middle of one end of the outer wall of the third U-shaped round rod, a second internal screw groove rod is fixedly installed. In the middle of the upper end of the concave bracket, a first hollow clamping block is fixedly installed.

[0009] Preferably, the main connection assembly includes a pushing mechanism and support mechanisms movably installed on both sides of the lower end of the pushing mechanism. At the lower end of the support mechanism, a right-angle block is movably installed. On one side of the upper end of the right-angle block, an inclined strut is movably installed.

[0010] Preferably, the pushing mechanism includes a fifth U-shaped round rod and first hollow round sleeve columns fixedly installed on both sides of the lower end of the fifth U-shaped round rod. At the lower end of the first hollow round sleeve column, a first semi-circular block is integrally formed. In the middle of the inner cavity of the first semi-circular block, a plug rod is fixedly installed.

[0011] Preferably, the support mechanism includes a long rod and a second hollow round sleeve column fixedly installed at one end of the long rod. At one end of the second hollow round sleeve column, a corresponding semi-circular block is fixedly installed. In the middle of the inner cavity of the corresponding semi-circular block, an annular groove is installed.

[0012] Preferably, the driven assembly includes a fourth U-shaped round rod and sixth U-shaped round rods movably installed on both sides of one end of the fourth U-shaped round rod. On both sides of the lower end of the sixth U-shaped round rod, convex blocks are respectively movably installed. In the middle of one end of the fourth U-shaped round rod, a second hollow clamping block is fixedly installed.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When the trolley is not in use, by pressing the fifth U-shaped round rod forward and downward, the first semi-circular block at one end of the fifth U-shaped round rod and the corresponding semi-circular block rotate, so that the long rod folds forward. At the same time, when the long rod folds forward, the movably installed inclined strut will also lean forward, so that the inclined strut drives the first U-shaped round rod and the third U-shaped round rod to lean forward. Since the driven assembly is movably installed on both sides of the inner wall of the third U-shaped round rod and moves forward and downward together with the third U-shaped round rod, when the lower end of the third U-shaped round rod contacts and places on the upper end of the vehicle floor, the folding and storage of the trolley are completed, which is convenient for carrying the folding cart when it is not in use.

[0015] 2. When the pet gets off the vehicle, the T-shaped screw threadedly connected in the inner cavity of the first internal screw groove rod can be loosened, so that the first hollow clamping block is taken out from one end of the first internal screw groove rod. Since both sides of one end of the second U-shaped round rod are movably installed on one end of the inner wall of the concave bracket, the other end of the second U-shaped round rod contacts the ground, and the pet can get off the vehicle from the second U-shaped round rod, which is convenient to use.

When the pet gets off the vehicle, the T-shaped screw threadedly connected in the inner cavity of the first inner screw groove rod 54 can be loosened, so that the first hollow clamping block 58 can be taken out from one end of the first inner screw groove rod 54. Since both sides of one end of the second U-shaped round rod 53 are movably installed on one end of the inner wall of the concave bracket 51, the other end of the second U-shaped round rod 53 contacts the ground, and the pet can get off the vehicle from the second U-shaped round rod 53. When the trolley is not in use, by pressing the fifth U-shaped round rod 611 forward and downward, the first semi-circular block 613 at one end of the fifth U-shaped round rod 611 and the corresponding semi-circular block 623 rotate, so that the long rod 621 folds forward (towards the first sliding wheel 2), and at the same time when the long rod 621 folds forward, it will drive the movably installed diagonal strut 64 to lean forward together, so that the diagonal strut 64 drives the first U-shaped round rod 52 and the third U-shaped round rod 56 to lean forward. Since the driven component 7 is movably installed on both sides of the inner wall of the third U-shaped round rod 56 and moves forward together with the third U-shaped round rod 56, when the lower end of the third U-shaped round rod 56 contacts and is placed on the upper end of the vehicle floor board 1, the folding and storage of the trolley are completed.

[0032] The second hollow round sleeve column 622, the corresponding semi-circular block 623, the circular ring groove 624, the first hollow round sleeve column 612, the first semi-circular block 613 and the insertion rod 614 together form a locking large joint, and the model of the locking large joint is HP-716.
