Abstract
Description
Technical Field
[0001] This utility model belongs to the field of storage carts, and specifically relates to a multifunctional storage cart. Background Technology
[0002] In production or repair workshops, some workers often use trolleys to store tools for easy storage. For example, during the manufacturing process of a carriage, tools such as hammers, scissors, screwdrivers, pliers, and measuring tapes are often used. Due to the large number of tools, tool carts are needed for easy carrying. However, with current technology, traditional tool carts are simply frame structures. Although they have storage functions, they cannot be adapted to different environments. For example, when processing or repairing the bottom of the carriage, some tool carts are too high to enter, requiring workers to repeatedly enter and exit to retrieve tools, which is inconvenient. On the other hand, if the tool cart is too low, it is inconvenient to retrieve tools normally, and the storage space is also reduced. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a multi-functional storage trolley is proposed. This addresses the issue that traditional tool carts, while possessing storage capabilities, are limited by their simple frame structure and cannot be adapted to different environments. For instance, when processing or repairing the bottom of the cart, some tool carts are too high to access, requiring workers to repeatedly enter and exit to retrieve tools, which is inconvenient. On the other hand, if the tool cart is too low, it is inconvenient to retrieve tools during normal use, and the storage space is also reduced.

Detailed Implementation
[0028] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.
[0029] Example 1:
[0030] This utility model provides a multifunctional storage trolley: its structure includes a first base plate 1, a second base plate 2, a first telescopic component 3, shelves 4, side rods 5, frame rods 6, handles 7, a storage box 8, casters 9, and a second telescopic component 10. The second telescopic component 10 is provided inside the first base plate 1, and the second base plate 2 is located on one side of the first base plate 1. One end of the second telescopic component 10 passes through the first base plate 1 and is fixedly connected to the second base plate 2. Casters 9 are mounted on the bottom of both the first base plate 1 and the second base plate 2. The frame rods 6 are arranged in pairs, with each pair of frame rods 6 arranged in parallel. Shelves 4 are fixedly mounted on each pair of frame rods 6. The first base plate 1 is fixedly connected to a set of the frame rods 6. The side rods 5 are arranged in groups of four, and each group of side rods 5 is assembled in parallel. Each pair of frame rods 6 is hinged together by a set of side rods 5. The four side rods 5 in each group are assembled in pairs on opposite parallel sides of each pair of frame rods 6. The topmost set of frame rods 6 is fixedly connected to the storage tank 8. The bottom of the storage tank 8 is also fixedly connected to one end of the first telescopic member 3. The other end of the first telescopic member 3 is fixedly connected to the second base plate 2. The side end face of the storage tank 8 is also equipped with a handle 7. The first telescopic member 3 and the second telescopic member 10 can lock the telescopic length.
[0031] The first telescopic component 3 and the second telescopic component 10 are scissor-type lifting structures of telescopic rods or lifting platforms.
[0032] When using the device, if it needs to be used in a lower location, such as under a vehicle, the first telescopic component 3 and the second telescopic component 10 can be unlocked first. Then, push the lower shelf 4 or the support rod 6 to separate the first base plate 1 and the second base plate 2. After separation, the first base plate 1 and the second base plate 2 remain connected by the second telescopic component 10 to ensure stability. During separation, since each set of support rods 6 is equipped with a shelf 4, and each pair of support rods 6 is hinged by parallel side rods 5, the support rods of each pair of support rods 6 will only swing parallel to each other. In addition, since the support rods 6 are connected to the storage box 8, and one end of the storage box 8 is also connected to the first telescopic component 10, the separation is further facilitated by the second telescopic component 10. The reason why component 3 will not be tilted is that each set of frame poles 6 will unfold synchronously and parallelly when unfolded, which will not cause the shelf 4 to tilt. This allows the trolley to unfold in a stepped manner. After unfolding to the required height, the height can be locked by locking the first telescopic component 3 and the second telescopic component 10. The temporarily opened shelf 4 in a stepped manner can still be stored without affecting the storage space. This allows the trolley to be used in lower places when needed. The stepped unfolding and height locking also allows the equipment to be used as a temporary step, achieving multi-functionality. It is convenient to enter the carriage and use it for heightening purposes. It has strong applicability and functionality and is easy to use.
[0033] Example 2:
[0034] Compared to Embodiment 1, in this embodiment, the first telescopic member 3 and the second telescopic member 10 are internally sealed pneumatic telescopic rods. The top of the first telescopic member 3 is fixedly connected to the storage tank 8 through a control block 12. Both the control block 12 and the second base plate 2 are provided with ventilation structures 11. The ventilation structures 11 are used for opening and closing the interior of the first telescopic member 3 and the second telescopic member 10.
[0035] The ventilation structure 11 consists of a ventilation hole 1101 and an air valve 1102. The ventilation hole 1101 is located in the control block 12 and the second base plate 2. The ventilation hole 1101 is used to connect the first telescopic member 3 with the air valve 1102 or the second telescopic member 10 with the air valve 1102. The air valve 1102 is used to control the opening and closing of the ventilation hole 1101.
[0036] In use, the extension and locking of the first telescopic member 3 and the second telescopic member 10 can be adjusted by adjusting the air valve 1102. It also makes it easier to adjust the adjustment rate of the first telescopic member 3 and the second telescopic member 10, avoiding rapid retraction after the first telescopic member 3 and the second telescopic member 10 are unlocked, making it easier to unfold and adjust for use. The rest of the structure and effect remain unchanged.
[0037] Example 3:
[0038] Compared to the previous embodiments, in this embodiment, the first telescopic member 3 and the second telescopic member 10 are electric push rods, pneumatic cylinders, or hydraulic cylinders. In use, the extension and retraction of the first telescopic member 3 and the second telescopic member 10 can be controlled by electric control, which makes it easier to adjust and use, and can be automatically adjusted. The rest of the structure and effect remain unchanged.

[0040] Compared to the previous embodiments, in this embodiment, the bottom of the shelf 4 is provided with a pin 401, the frame rod 6 is an L-shaped plate, and the frame rod 6 is provided with a through hole 601. The shelf 4 is assembled by inserting the pin 401 into the through hole 601 of the frame rod 6.
[0041] The frame rod 6 is also provided with a reinforcing rib 602, which is fixed between the two plates of the L-shaped structure of the frame rod 6.
[0042] When in use, the shelf 4 can be lifted to quickly connect and disconnect from each set of support rods 6, which facilitates subsequent maintenance and replacement. The rest of the structure and effect remain unchanged.
[0043] Example 5:
[0044] Compared to the previous embodiments, the handle 7 in this embodiment has an arc-shaped structure and an upward arched structure. When temporary steps or the like are used, the arc-shaped handle 7 can be used to support the handle at a designated position for positioning. The arc-shaped structure makes it easier to support the handle stably, while the rest of the structure and effect remain unchanged.
[0045] Example 6:
[0046] Compared to the previous embodiments, the storage tank 8 in this embodiment includes a tank body 801, a tank cover 802, and a magnet 803. The top of the tank body 801 is hinged to the tank cover 802 near the first telescopic member 3. A magnet 803 is provided between the tank cover 802 and the tank body 801 on the side away from the hinge. The magnet 803 is used to attract the closure of the tank cover 802.
