Description

Technical Field

[0001] This utility model relates to the field of handcart technology, specifically to a folding handcart. Background Technology

[0002] A gardencart is a manually pushed or pulled transport vehicle, and it is the ancestor of all vehicles. Although material handling technology using gardencarts has continuously developed, they remain an indispensable transport tool to this day. Gardencarts are widely used in production and daily life because they are inexpensive, easy to maintain, convenient to operate, and lightweight. They can work in places where motor vehicles are inconvenient to use and are very convenient for moving lighter items over short distances. However, traditional gardencarts often have a fixed structure and size to ensure structural stability. This not only makes them inconvenient to carry but also takes up a lot of space, as the angled structure of a gardencart inevitably wastes considerable space.

[0003] Chinese patent discloses a folding handcart (authorization announcement number CN 209904780 U). This patented technology can retract the push handle into the frame through a limiting device, fold the placement plate through a rotating device, and quickly remove and separate the moving wheels and connecting rods through quick-release moving wheels, thus completing the folding of the handcart into a flat structure that does not occupy extra space. It is also sturdy and robust, and the ability to fold part of the structure makes it convenient to carry and store. Its plate is concave, so cylindrical goods will not easily roll back and forth. However, when the device is being stored, the handlebars are not convenient to store, and when the handcart is not in use, the handlebars occupy space and are inconvenient to place.

[0004] Therefore, those skilled in the art have provided a folding trolley to solve the problems mentioned in the background art. Utility Model Content

[0020] Example

[0021] Please see Figures 1-5This embodiment provides a folding handcart, including a body 1. Four symmetrical casters 2 are installed at the bottom of the body 1, facilitating movement of the handcart. A handle 3, shaped like an inverted U, is installed on the top right of the body 1. A limiting groove 31 is formed at the bottom of the handle 3, and a folding mechanism is installed within the limiting groove 31. This mechanism allows the handle 3 to be folded for storage when the handcart is not in use, avoiding space occupation. A baffle 7 is installed on the lower side of the handle 3, fixedly mounted on the body 1. The baffle 7 blocks the transported goods, preventing them from sliding off the back of the handcart while it is being pushed. Several support rods are provided at the bottom of the baffle 7 to support it. A handle 71 is installed on the right side of the baffle 7, with two symmetrical handles at the front and back. Holding the handle 71 facilitates carrying the handcart and loading it onto a truck, simplifying subsequent transportation.

[0022] The folding mechanism includes mounting plates 5, which are arranged symmetrically front and back. The two mounting plates 5 are installed on the outer side of the handrail 3. Mounting rods 51 are installed on the two mounting plates 5. The two mounting rods 51 pass through two limiting grooves 31 respectively. When the folding mechanism needs to fold the handrail 3, the handrail 3 is pulled upward, which allows the mounting rods 51 to move up and down within the limiting grooves 31, thereby moving the handrail 3 upward. The handrail 3 can also rotate 180 degrees on the mounting rods 51, which makes it easy to rotate the handrail 3 and fold it for storage when the handcart is not in use, and also for transportation of the handcart later.

[0023] A locking plate 4 is installed in the middle of the handrail 3, and the locking plate 4 is located on the upper side of the baffle 7. The rear side of the locking plate 4 is provided with a locking groove, which can be locked onto the locking plate 4. The top of the locking plate 4 is provided with a locking hole 41, and the rear side of the baffle 7 is provided with an insertion hole, which corresponds to the locking hole 41. A locking bolt 6 is installed in the locking hole 41, and the bottom end of the locking bolt 6 is inserted into the insertion hole of the baffle 7. A connecting chain 61 is installed on the top of the locking bolt 6, and the other end of the connecting chain 61 is installed on one side of the locking plate 4. By locking the locking plate 4 with the locking groove onto the baffle 7, the handrail 3 stands vertically on the upper side of the baffle 7, thereby installing the handrail 3. Then, the locking bolt 6 connected by the connecting chain 61 is locked into the locking hole 41 to prevent the handrail 3 from moving at will, and the connecting chain 61 can prevent the locking bolt 6 from being lost.

[0024] The working principle of this utility model is as follows: When using the handcart, by lifting the handlebar, the slot of the clamping plate 4 is aligned with the baffle 7, and then the clamping plate 4 is fitted into the baffle 7, thereby completing the installation of the handlebar 3. Then, the bolt 6 is locked in the locking hole 41 to prevent the handlebar 3 from moving randomly. The connecting chain 61 can prevent the bolt 6 from being lost. When it is necessary to fold the handlebar 3, first remove the bolt 6, and then pull the handlebar 3 upward, so that the mounting rod 51 can move up and down in the limiting groove 31, driving the handlebar 3 to move upward, thereby rotating the handlebar 3 and making it easy to fold the handlebar 3 for storage when the handcart is not in use.
