Description

Technical Field

[0001] This utility model relates to the field of tool cart technology, and in particular to a foldable tool cart. Background Technology

[0002] Foldable tool carts are trolleys that can be folded to reduce their size. Designed for easy carrying and storage, foldable tool carts are transport tools primarily used for convenient storage and transportation. They are typically made of metal and are lightweight, durable, and easy to fold, making them suitable for use in various scenarios. Tool carts can safely and efficiently transport tools and accessories on the production floor, providing great convenience to production. However, most existing tool carts have fixed frame structures, making them inconvenient to store after use and taking up a lot of space.

[0003] An existing foldable tool cart has limited carrying capacity, making it inconvenient to unfold and store the tool cart according to the actual use situation, thus limiting the ease of operation when using the tool cart. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a foldable tool cart.

[0005] The present invention is achieved by the following technical solution: a foldable tool cart, including a tool cart, a movable wheel rotatably connected to the bottom of the tool cart, and a handrail fixedly connected to the top of the tool cart;

[0006] The tool cart is rotatably connected to a rotating frame on its surface. A folding support plate is rotatably connected inside the rotating frame. A protective baffle is fixedly connected to the top of the folding support plate. A fixing frame is fixedly connected to the surface of the protective baffle. A second movable wheel is threadedly connected to the top of the fixing frame. A limit block is engaged inside the fixing frame. A handle is fixedly connected to the surface of the limit block. A pull handle is fixedly connected to the top of the folding support plate. A protective rubber pad is fixedly connected to the bottom of the folding support plate.

[0007] As a further improvement to the above solution, the number of the first movable wheels is set to two, and the two first movable wheels are symmetrically distributed front and back around the tool cart, with the handrail frame located at the rear end of the folding support plate.

[0008] As a further improvement to the above scheme, the number of rotating frames is set to two, and the two rotating frames are symmetrically distributed on the left and right sides with the tool cart as the center.

[0009] The above technical solution involves two rotating frames symmetrically distributed around the tool cart, with internal rotating connections to foldable support plates. This foldable structure helps reduce the space occupied by the tool cart when not in use, making it convenient for storage.

[0010] As a further improvement to the above solution, the number of fixed card frames and movable wheels is set to four, with each pair forming a group, and the four fixed card frames and movable wheels are symmetrically distributed on the left and right sides with the folding support plate as the center.

[0011] With the above technical solution, the number of fixed card frames and two movable wheels is four, and they are symmetrically distributed on the left and right sides with the folding support plate as the center. This symmetrical distribution helps to enhance the stability of the folding support plate when it is unfolded, making it less likely for items placed on it to tip over.

[0012] As a further improvement to the above solution, the number of the limiting blocks and handles is set to four, and each pair forms a group, with the four limiting blocks and handles symmetrically distributed around the folding support plate.

[0013] As a further improvement to the above solution, the bottom of the protective rubber pad contacts the top surface of the tool cart, and the number of the protective rubber pads is set to four, which are symmetrically distributed around the folding support plate.

[0014] As a further improvement to the above solution, the limiting block is located on the top of the tool cart, and the handle is also located on the top of the tool cart.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model increases the load-bearing area of ​​the tool cart by pulling the handle to rotate and unfold the folding support plate and the rotating frame inside the tool cart. When the limit block is removed from the fixed frame by pulling the handle, it is easy to remove the moving wheels from the fixed frame. When the folding support plate and the bottom protective pad are used to store the folded product on the top of the tool cart, it increases the convenience of using the equipment.

[0017] This utility model features four limiting blocks and handles symmetrically distributed around the folding support plate. The limiting blocks and handles are located on the top of the tool cart. By operating the handles to move the limiting blocks, the unfolded or folded state of the folding support plate can be easily fixed. The operation is simple and convenient. Four protective rubber pads are symmetrically distributed around the folding support plate, with their bottoms in contact with the top surface of the tool cart. When the folding support plate is lowered, the protective rubber pads can not only act as a buffer to protect the top surface of the tool cart, but also increase friction, making the folding support plate more stable.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5 The foldable tool cart of this embodiment includes a tool cart 1, with a movable wheel 2 rotatably connected to the bottom of the tool cart 1 and a handrail 3 fixedly connected to the top of the tool cart 1.

[0028] The tool cart 1 is rotatably connected to a rotating frame 4. A folding support plate 5 is rotatably connected inside the rotating frame 4. A protective baffle 6 is fixedly connected to the top of the folding support plate 5. A fixing frame 7 is fixedly connected to the surface of the protective baffle 6. A second movable wheel 8 is threadedly connected to the top of the fixing frame 7. A limit block 9 is engaged inside the fixing frame 7. A handle 10 is fixedly connected to the surface of the limit block 9. A pull handle 11 is fixedly connected to the top of the folding support plate 5. A protective rubber pad 12 is fixedly connected to the bottom of the folding support plate 5. Pulling the pull handle 11 causes the folding support plate 5 to rotate and unfold inside the tool cart 1 in conjunction with the rotating frame 4, increasing the original load-bearing area of ​​the tool cart 1. Pulling the handle 10 causes the limit block 9 to be removed from inside the fixing frame 7, facilitating the removal and installation of the second movable wheel 8 from inside the fixing frame 7. When the folding support plate 5, in conjunction with the protective rubber pad 12 at the bottom, stores the folded product on top of the tool cart 1, it increases the convenience of using the equipment.

[0029] The number of movable wheels 2 is set to two, and the two movable wheels 2 are symmetrically distributed front and back around the tool cart 1. The handrail 3 is located at the rear end of the folding support plate 5.

[0030] The number of rotating frames 4 is set to two, and the two rotating frames 4 are symmetrically distributed on the left and right sides with the tool cart 1 as the center.

[0031] There are two rotating frames 4, which are symmetrically distributed on the left and right sides with the tool cart 1 as the center. The internal rotating frame is connected to a folding support plate 5. This foldable structure helps to reduce the space occupied by the tool cart 1 when it is not in use, and makes it convenient to store.

[0032] The number of fixed card frames 7 and movable wheels 8 is set to four, and each pair is a group of four. The four fixed card frames 7 and movable wheels 8 are symmetrically distributed on the left and right sides with the folding support plate 5 as the center.

[0033] The fixed card frame 7 and the two movable wheels 8 are four in number and are symmetrically distributed on the left and right sides with the folding support plate 5 as the center. This symmetrical distribution helps to enhance the stability of the folding support plate 5 when it is unfolded, making it less likely for items placed on it to tip over.

[0034] The number of limiting blocks 9 and handles 10 is set to four, with each pair forming a group. The four limiting blocks 9 and handles 10 are symmetrically distributed around the folding support plate 5. By setting the number of limiting blocks 9 and handles 10 to four and symmetrically distributed around the folding support plate 5, the limiting blocks 9 are located on the top of the tool cart 1, and the handles 10 are located on the top of the tool cart 1. By operating the handles 10 to drive the limiting blocks 9, the unfolded or folded state of the folding support plate 5 can be easily fixed. The operation is simple and convenient. By setting the bottom of the protective rubber pads 12 to contact the top surface of the tool cart 1, and setting the number of four to be symmetrically distributed around the folding support plate 5, the protective rubber pads 12 can not only play a buffering role and protect the top surface of the tool cart 1 when the folding support plate 5 is lowered, but also increase the friction and make the folding support plate 5 more stable.

[0035] The bottom of the protective rubber pad 12 contacts the top surface of the tool cart 1. The number of protective rubber pads 12 is set to four, and the four protective rubber pads 12 are symmetrically distributed around the folding support plate 5.

[0036] The limit block 9 is located on the top of the tool cart 1, and the handle 10 is located on the top of the tool cart 1.

[0037] The implementation principle of a foldable tool cart in this embodiment is as follows: pulling the handle 11 causes the folding support plate 5 to rotate and unfold inside the tool cart 1 in conjunction with the rotating frame 4, increasing the original load-bearing area of ​​the tool cart 1. Pulling the handle 10 causes the limiting block 9 to be removed from inside the fixed frame 7, facilitating the installation and removal of the moving wheels 8 from inside the fixed frame 7. When the folding support plate 5, together with the bottom protective pad 12, stores the folded product on top of the tool cart 1, it increases the convenience of using the equipment. By setting the limiting block 9 and the handle 10... Four protective pads 12 are symmetrically distributed around the folding support plate 5. The limiting block 9 is located on the top of the tool cart 1, and the handle 10 is located on the top of the tool cart 1. By operating the handle 10 to drive the limiting block 9, the unfolded or folded state of the folding support plate 5 can be easily fixed. The operation is simple and convenient. By setting the bottom of the protective pads 12 to contact the top surface of the tool cart 1, and symmetrically distributed around the folding support plate 5, the protective pads 12 can not only play a buffering role and protect the top surface of the tool cart 1 when the folding support plate 5 is lowered, but also increase the friction and make the folding support plate 5 more stable.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
