[0001] The utility model relates to the technical field of flatbed trolleys, in particular to a foldable and strong flatbed trolley. Background Art

[0002] Flatbed trolleys are divided into quick-folding type and fixed-handle type. For the quick-folding type, you can step on the fixed cross bar with your foot and then push the handle down to fold it. It can be folded quickly; for the fixed-handle type, the handle is fixed and welded on the flatbed trolley, which is relatively sturdy and durable.

[0003] In the process of implementing this application, it was found that the technology has the following problems: the handle of the existing cart folding mechanism is easily deformed when subjected to force during use, making the cart difficult to use or unable to be folded again, and the force-bearing area of ​​the round tube clamping position is too small to easily cause the tube to deform and cause damage to the handle, thereby reducing the practicality of the device.

[0004] For this reason, a foldable and strong flatbed trolley is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems that the handle of the existing cart folding mechanism is easily deformed when subjected to force during use, making the cart difficult to use or unable to fold again, and the force-bearing area of ​​the round tube clamping position is too small to easily cause the tube to deform and cause damage to the handle. The utility model provides a foldable and sturdy flatbed cart.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A foldable and sturdy flatbed trolley comprises a cargo panel, the lower surface of which is provided with four sets of casters, the upper surface of which is provided with two sets of folding mechanisms for pushing the cargo panel to move above the ground at multiple angles, and handles are installed on adjacent sides of the two sets of folding mechanisms.

[0008] Furthermore, the two groups of folding mechanisms include a pull rod and a folding outer seat, the two groups of folding outer seats are installed on the upper surface of the cargo panel, the front and rear sides of the two groups of folding outer seats are provided with through holes, the two groups of through holes of the two groups of folding outer seats are rotatably connected with fixing pins, the two groups of pull rods are respectively installed on the outer surfaces of the two groups of fixing pins, the front and rear end upper surfaces of the two groups of folding outer seats are provided with positioning grooves, the front sides of the two groups of pull rods are provided with movable grooves, the insides of the two groups of movable grooves are slidably connected with movable pins, and the positions of the two adjacent groups of positioning grooves are respectively located on the moving paths of the two groups of movable pins.

[0009] Furthermore, the right sides of the two groups of pull rods and the upper surface of the cargo panel form an angle of sixty degrees.

[0010] Furthermore, the distance between the lower surface of the cargo panel and the ground is three centimeters.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model positions the two groups of pull rods by using a fixed pin and a movable pin in the folding mechanism, so that the folding mechanism can be self-locking during positioning and use, and the folding mechanism does not need to use a spring to lock itself during use, thereby simplifying the internal parts of the folding mechanism, thereby reducing the production cost of the folding mechanism, and thus improving the practicality of the device; during the use of the folding mechanism, the movable pin is pushed and inserted from the bottom to the inside of the two groups of positioning grooves, so that the movable pin self-locks the pull rod in the position inside the folding outer seat, and thus there is no welding or screws on the upper end of the cargo panel, thereby minimizing the subsequent cargo from being scratched by the screws on the upper end of the cargo panel when the device is used for loading.

[0013] 2. The utility model has a shorter distance between the lower surface of the cargo panel and the ground, so that subsequent workers can quickly lift the goods to the upper surface of the cargo panel, thereby reducing the labor and time consumed by subsequent workers when using the device to transport goods; the shorter distance between the upper surface of the cargo panel and the ground makes the center of gravity of the cargo panel lower during use, thereby minimizing the tipping over of the subsequent cargo panel during use, thereby improving the stability of the cargo panel during use.

[0023] like Figures 1 to 4 As shown, a foldable and sturdy flatbed trolley includes a cargo panel 1, four sets of casters 2 are installed on the lower surface of the cargo panel 1, and two sets of folding mechanisms 3 are provided on the upper surface of the cargo panel 1 for pushing the cargo panel 1 to move above the ground at multiple angles, and a handle 4 is installed on the adjacent side of the two sets of folding mechanisms 3; specifically, the folding mechanism 3 is self-locking during positioning and use, so that the folding mechanism 3 does not need to use a spring to control itself during use, thereby simplifying the internal parts of the folding mechanism 3, thereby reducing the production cost of the folding mechanism 3, and thus improving the practicability of the device; the folding mechanism 3 does not have any welding or screws during use, thereby minimizing the subsequent goods from being scratched by the screws on the upper end of the cargo panel 1 when the device is used for loading.

[0024] like Figures 1 to 4As shown, the two groups of folding mechanisms 3 include a pull rod 301 and a folding outer seat 302. The two groups of folding outer seats 302 are installed on the upper surface of the cargo panel 1. Through holes are provided on the front and rear sides of the two groups of folding outer seats 302. The two groups of through holes of the two groups of folding outer seats 302 are rotatably connected with fixed pins 303. The two groups of pull rods 301 are respectively installed on the outer surfaces of the two groups of fixed pins 303. The upper surfaces of the front and rear ends of the two groups of folding outer seats 302 are provided with positioning grooves 305. The front surfaces of the two groups of pull rods 301 are provided with movable grooves 306. The two groups of movable grooves 306 are provided with positioning grooves 306. There are movable pins 304 slidably connected inside, and the positions of the two adjacent groups of positioning grooves 305 are respectively located on the moving paths of the two groups of movable pins 304; specifically, the positions of the two groups of pull rods 301 are positioned by using the fixed pins 303 and the movable pins 304 inside the folding mechanism 3, so that the folding mechanism 3 is self-locking during the positioning and use process, and then the folding mechanism 3 does not need to use springs to lock itself during use, thereby simplifying the internal parts of the folding mechanism 3, thereby reducing the production cost of the folding mechanism 3, and thus improving the practicality of the device. During the use of the folding mechanism 3, the movable pin 304 is pushed and inserted from the bottom to the top of the two groups of positioning grooves 305, so that the movable pin 304 self-locks the pull rod 301 in the position inside the folding outer seat 302, and then there is no welding or screws on the upper end of the cargo panel 1, thereby minimizing the subsequent cargo from being scratched by the screws on the upper end of the cargo panel 1 when the device is used for loading.

[0025] like Figure 1 and Figure 2 As shown, the right sides of the two sets of pull rods 301 and the upper surface of the cargo panel 1 form an angle of sixty degrees; specifically, when the folding mechanism 3 is opened, the angle between the upper surface of the cargo panel 1 is sixty degrees, so that the cargo panel 1 is away from the user during use, thereby minimizing the possibility that the cargo panel 1 hits the user's feet when the subsequent user pulls the cargo panel 1 to move, thereby improving the safety of the device during use.

[0026] like Figure 1 and Figure 2 As shown, the distance between the lower surface of the cargo panel 1 and the ground is three centimeters; specifically, the shorter distance between the lower surface of the cargo panel 1 and the ground allows subsequent staff to quickly lift the goods to the upper surface of the cargo panel 1, thereby reducing the labor and time consumed by subsequent staff when using the device to transport goods; the shorter distance between the upper surface of the cargo panel 1 and the ground allows the center of gravity of the cargo panel 1 to be lower during use, thereby minimizing the tipping over of the subsequent cargo panel 1 during use, thereby improving the stability of the cargo panel 1 during use.

[0027] In summary: by using the fixed pin 303 and the movable pin 304 inside the folding mechanism 3 to position the two groups of pull rods 301, the folding mechanism 3 can be self-locking during positioning and use, and the folding mechanism 3 does not need to use a spring to lock itself during use, thereby simplifying the internal parts of the folding mechanism 3 and reducing the production cost of the folding mechanism 3; by using the movable pin 304 to push the movable pin 304 during use, the movable pin 304 is inserted from bottom to top into the two groups of positioning grooves 305, so that the movable pin 304 self-locks the pull rod 301 in the position inside the folding outer seat 302, and there is no welding or screws on the upper end of the cargo panel 1, thereby minimizing the subsequent cargo from being scratched by the screws on the upper end of the cargo panel 1 when the device is used for loading.

[0028] At the same time, the angle between the folding mechanism 3 and the upper surface of the cargo panel 1 when opened is sixty degrees, so that the cargo panel 1 is away from the user during use, thereby minimizing the cargo panel 1 from hitting the user's feet when the subsequent user pulls the cargo panel 1 to move.
