Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a utility vehicle. Background Technology

[0002] Tool carts are vehicles or mobile devices specifically designed for transporting, storing, and organizing tools and equipment, typically serving industrial, maintenance, construction, and logistics applications. However, current tool carts are generally quite large, resulting in high storage and transportation costs. Utility Model Content

[0003] Therefore, it is necessary to provide a tool vehicle that is both easy to use and can effectively reduce transportation and storage costs.

[0004] This application provides a tool cart, including: a first storage platform, a second storage platform, and a support. The second storage platform is disposed above the first storage platform, and the support connects the first storage platform and the second storage platform. The support is foldable so that the tool cart has a folded state and an unfolded state. When the tool cart is in the folded state, the distance between the first storage platform and the second storage platform is less than the distance between the first storage platform and the second storage platform when the tool cart is in the unfolded state.

[0005] In one embodiment, the tool cart has a first end and a second end opposite to each other. The support includes a first column at the first end and a second column at the second end. One end of the first column is rotatably connected to the first shelf, and the other end is rotatably connected to the second shelf via a first adapter. One end of the second column is rotatably connected to the second shelf, and the other end is rotatably connected to the first shelf via a second adapter. When the tool cart is in the unfolded state, the shelf surface of the second shelf faces upward; when the tool cart is in the folded state, the shelf surface of the second shelf faces downward. This configuration makes the tool cart easy to fold and unfold, and its operation is very simple. Merchants can save space and reduce transportation costs by folding the tool cart when selling it. Buyers can simply unfold the tool cart upon receiving it for immediate use, which is very convenient and avoids the tedious operation of assembling parts.

[0006] In one embodiment, the first shelf has a first clearance groove corresponding to the first column, and the second shelf has a second clearance groove corresponding to the second column. When the tool cart is in a folded state, the first column is at least partially accommodated in the first clearance groove, and the second column is at least partially accommodated in the second clearance groove. This arrangement can further shorten the distance between the first shelf and the second shelf in the folded state, making the tool cart smaller in size when folded, thus saving space for storage and transportation.

[0007] In one embodiment, the tool cart further includes a locking mechanism for locking the tool cart in the unfolded state. This configuration ensures that the tool cart remains stable when unfolded for use.

[0008] In one embodiment, one end of the first adapter is rotatably connected to the second shelf, and the other end is sleeved on the second column. The locking mechanism includes a first locking component disposed at the connection between the first column and the second shelf. The first locking component includes a first locking member, a first elastic member, and a first unlocking member. The first locking member is movably disposed on the second shelf. The first unlocking member is connected to the first locking member and is used to control the first locking member to move to the unlocked state. The first elastic member acts on the first locking member to make the first locking member tend to move to the locked state. In the natural state, the first locking member locks the connection between the first adapter and the first column to the second shelf under the elastic force of the first elastic member. When the first unlocking member controls the first locking member to move to the unlocked state, the connection between the first adapter and the first column can leave the second shelf. With this configuration, in its natural state, the first locking element is locked. At this time, the first adapter cannot rotate relative to the second shelf, nor can it move along the first column. Consequently, the first column cannot rotate relative to the first shelf, and the second shelf cannot rotate relative to the second column. Therefore, locking the first adapter and the first column with the first locking element ensures the tool cart remains stably in its unfolded state. When the tool cart needs to be folded, the first unlocking element controls the first locking element to move to the unlocked state. This allows the connecting part between the first adapter and the first column to separate from the second shelf, enabling the first adapter to rotate relative to the second shelf and slide along the first column. Simultaneously, the first column can rotate relative to the first shelf, and the second shelf can rotate relative to the second column, allowing the first column to be rotated from a vertical to a horizontal position. Additionally, the end of the second shelf connected to the first adapter can rotate to the lower end of the second column.

[0009] In one embodiment, the second column is rotatably connected to the first shelf via a second adapter. One end of the second adapter is rotatably connected to the first shelf, and the other end is fixedly connected to the second column. The locking mechanism includes a second locking component located at the connection between the second column and the first shelf. The second locking component includes a second locking member, a second unlocking member, a second elastic member, and a third elastic member. The second locking member is horizontally movably mounted on the first shelf, and the second unlocking member is vertically movably mounted on the first shelf. The side wall of the second unlocking member has a guide groove that slopes downwards towards the second adapter. The second locking member has a guide post that passes through the guide groove and can move along the guide groove. The guide groove moves, the second elastic member abuts between the second locking member and the first shelf, and the third elastic member abuts between the second unlocking member and the first shelf. In the natural state, the second unlocking member moves to its highest position under the elastic force of the third elastic member, the guide post is located at the lower end of the guide groove, the second locking member compresses the second elastic member, and one end of the second locking member locks the second adapter. When the second unlocking member moves downward to its lowest position, the second unlocking member compresses the third elastic member, and the second locking member moves away from the second adapter under the elastic force of the second elastic member, thus releasing the lock on the second adapter. The guide post is located at the upper end of the guide groove. With this configuration, in the natural state, the second locking member is in a locked state. At this time, the second adapter cannot rotate relative to the first shelf. Since the second adapter and the second post are fixedly connected, the second post cannot rotate relative to the first shelf either. Therefore, locking the second adapter with the second locking member keeps the second post in a vertical state, thereby allowing the tool cart to be stably kept in the unfolded state. When the tool cart needs to be folded, after the first column is folded to a horizontal position, the second unlocking member is pressed down, causing the second locking member to move to the unlocked position. This allows the second adapter and the second column to rotate relative to the first shelf, thereby rotating the second column and the second shelf from a vertical position to a horizontal position, with the second column located on the upward-facing side of the second shelf.

[0010] In one embodiment, the edge of the second shelf is provided with a groove. This arrangement allows hooks to be placed in the groove, enabling items to be hung on the hooks and increasing the storage capacity of the tool cart.

[0011] In one embodiment, the slot opening faces upward; or, the slot has a first slot portion and a second slot portion arranged opposite each other, with the opening of the first slot portion facing upward and the opening of the second slot portion facing downward; or, the slot penetrates the upper and lower end faces of the second shelf. With this configuration, the slot opening faces upward, allowing for the placement of hooks with an inverted U-shaped attachment. The slot having a first slot portion and a second slot portion arranged opposite each other, with the opening of the first slot portion facing upward and the opening of the second slot portion facing downward, allows for the placement of hooks with either an inverted U-shaped or C-shaped attachment, making it more convenient to use. The slot penetrating the upper and lower end faces of the second shelf allows for the placement of hooks with either an inverted U-shaped or C-shaped attachment, making it even more convenient to use.

[0012] In one embodiment, the groove extends along the side of the second shelf, and one end penetrates the side wall of the second shelf along the extension direction of the groove. This arrangement allows a hook to be hung in the groove from the end that penetrates the side wall of the second shelf. The groove in this embodiment is particularly suitable for hanging hooks with a C-shaped attachment point.

[0013] In one embodiment, the slots extend along the side of the second shelf, or there are multiple slots spaced apart along the side of the second shelf. This arrangement provides a longer hanging space for multiple hooks and items.

[0014] Compared with existing technologies, the tool cart provided in this application, by setting a foldable bracket, allows the distance between the first and second storage platforms to be adjustable. When needed, the tool cart can be switched to an unfolded state, in which case the distance between the first and second storage platforms is larger, and both platforms can be used to place items and are ready for normal use. When transportation or storage is required, the tool cart can be switched to a folded state, reducing the distance between the first and second storage platforms, thereby reducing the overall size of the tool cart and thus lowering transportation and storage costs.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0036] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figures 1 to 4 This application provides a tool cart, including: a first storage platform 10, a second storage platform 20, and a support 30. The second storage platform 20 is disposed above the first storage platform 10, and the support 30 connects the first storage platform 10 and the second storage platform 20. The support 30 is foldable, allowing the tool cart to have a folded state and an unfolded state. When the tool cart is in the folded state, the distance between the first storage platform 10 and the second storage platform 20 is less than the distance between the first storage platform 10 and the second storage platform 20 when the tool cart is in the unfolded state. Thus, by providing a foldable support 30, the distance between the first storage platform 10 and the second storage platform 20 is adjustable, allowing the tool cart to be switched to the unfolded state when needed. Figure 1 As shown, the distance between the first shelf 10 and the second shelf 20 is relatively large at this time, and both the first shelf 10 and the second shelf 20 can be used to place items and are in normal working order. When transportation or storage is required, the tool cart can be switched to a folding state, such as... Figure 4 As shown, the distance between the first storage platform 10 and the second storage platform 20 is reduced, thereby reducing the overall volume of the tool cart and thus reducing transportation and storage costs.

[0038] Furthermore, the tool cart has a first end 101 and a second end 102, and the support 30 includes a first column 31 disposed at the first end 101 and a second column 32 disposed at the second end 102. One end of the first column 31 is rotatably connected to the first shelf 10, and the other end is rotatably connected to the second shelf 20 via a first adapter 311. One end of the second column 32 is rotatably connected to the second shelf 20, and the other end is rotatably connected to the first shelf 10 via a second adapter 321. When the tool cart is in the unfolded state, as... Figure 1 As shown, the second shelf 20 has its storage surface facing upwards; when the tool cart is in the folded state, as... Figure 4 As shown, the second shelf 20 has its shelf surface facing downwards. Thus, combined with... Figures 1 to 4 When the tool cart is in the unfolded state, the second shelf 20 is supported by the first upright 31 and the second upright 32. To fold the tool cart, firstly, rotate the first upright 31 relative to the first shelf 10 and then rotate it relative to the second shelf 20. Simultaneously, rotate the second shelf 20 relative to the second upright 32. This moves the end connecting the first upright 31 and the second shelf 20 to the second end 102 of the tool cart, close to the first shelf 10. Then, control the second upright 32 to rotate relative to the first shelf 10, causing the second shelf 20 to flip so that its storage surface faces down, thus switching the tool cart to the folded state. At this time, the uprights are located on top of the second shelf 20. Reversing the operation will switch the tool cart to the unfolded state. As can be seen, the tool cart is easy to fold and unfold, and its operation is very simple. Therefore, when selling the tool cart, the seller can save space and reduce transportation costs by folding it. After receiving the tool cart, the buyer can unfold it and use it immediately, which is very convenient and avoids the tedious operation of assembling parts.

[0039] Furthermore, the first shelf 10 is provided with a first clearance groove 11 corresponding to the first column 31, and the second shelf 20 is provided with a second clearance groove 21 corresponding to the second column 32. When the tool cart is in the folded state, the first column 31 is at least partially accommodated in the first clearance groove 11, and the second column 32 is at least partially accommodated in the second clearance groove 21. In this way, the distance between the first shelf 10 and the second shelf 20 in the folded state can be further shortened, making the tool cart smaller in size when folded, thereby saving more space for storage and transportation.

[0040] In this application, both the first column 31 and the second column 32 are provided in pairs, so that when unfolded, the first column 31 and the second column 32 can stably support the second shelf 20. Furthermore, the first clearance groove 11 is provided on both sides of the first shelf 10, and the second clearance groove 21 is provided on the back of the second shelf 20, that is, on the side of the second shelf 20 opposite to the shelf surface.

[0041] Furthermore, the tool cart also includes a locking mechanism to lock the tool cart in the unfolded state. This ensures that the tool cart remains stable when unfolded for use.

[0042] Please see Figures 5 to 7 One end of the first adapter 311 is rotatably connected to the second shelf 20, and the other end is sleeved on the second column 32. The locking mechanism includes a first locking component 40 located at the connection between the first column 31 and the second shelf 20. The first locking component 40 includes a first locking member 41, a first elastic member 43, and a first unlocking member 42. The first locking member 41 is movably disposed on the second shelf 20. The first unlocking member 42 is connected to the first locking member 41 and is used to control the first locking member 41 to move to the unlocked state. The first elastic member 43 acts on the first locking member 41 to give it a tendency to move to the locked state. In its natural state, the first locking member 41, under the elastic force of the first elastic member 43, locks the connection between the first adapter 311 and the first column 31 to the second shelf 20. When the first unlocking member 42 controls the first locking member 41 to move to the unlocked state, the connection between the first adapter 311 and the first column 31 can be released from the second shelf 20. With this configuration, in its natural state, the first locking member 41 is in a locked state. At this time, the first adapter 311 cannot rotate relative to the second shelf 20, nor can it move along the first column 31. Therefore, the first column 31 cannot rotate relative to the first shelf 10, and the second shelf 20 cannot rotate relative to the second column 32. Thus, locking the first adapter 311 and the first column 31 with the first locking member 41 allows the tool cart to remain stably in the unfolded state. When the tool cart needs to be folded, the first unlocking member 42 controls the first locking member 41 to move to the unlocked state, allowing the connecting part between the first adapter 311 and the first column 31 to move away from the second shelf 20. This allows the first adapter 311 to rotate relative to the second shelf 20 and slide along the first column 31. Figure 2 and Figure 3 As shown. Simultaneously, the first column 31 can rotate relative to the first shelf 10, and the second shelf 20 can rotate relative to the second column 32, thereby allowing the first column 31 to be rotated from a vertical state to a horizontal state. At the same time, the end of the second shelf 20 connected to the first adapter 311 can rotate to the lower end of the second column 32, as shown. Figure 4 As shown.

[0043] In this embodiment, the first locking member 41 is a U-shaped member, and the first unlocking member 42 is connected to one end of the first locking member 41. The other end of the first locking member 41 passes through the side wall of the second shelf 20, the first adapter 311, and the first column 31 in sequence, locking the connection between the first adapter 311 and the first column 31 to the second shelf 20. The first unlocking member 42 is a button, which can control the movement of the first locking member 41 by pressing the button. The first elastic member 43 is a first spring, which is sleeved on the outside of the first locking member 41, and its two ends abut against the second shelf 20 and the first unlocking member 42, respectively. Thus, by pressing the first unlocking member 42, the first locking member 41 can be pushed to move, causing the end of the first locking member 41 to disengage from the first column 31 and the first adapter 311, thereby releasing the lock on the first column 31 and the first adapter 311, so that the first column 31 can rotate relative to the first shelf 10 to achieve folding. When the first unlocking member 42 is not pressed, under the elastic force of the first elastic member 43, one end of the first locking member 41 passes through the side wall of the second shelf 20, the first adapter 311, and the first column 31 in sequence, thereby locking the first column 31 and the first adapter 311, so that the tool cart can be stably kept in the unfolded state. It can be understood that when the tool cart is switched from the folded state to the unfolded state, the elastic force of the first elastic member 43 can make the first locking member 41 automatically insert into the first adapter 311 and the first column 31, which is very convenient to operate.

[0044] In this embodiment, the first unlocking member 42 is connected to the end of the first locking member 41 by screws, but it is not limited thereto. The first unlocking member 42 can also be connected to the first locking member 41 by other means such as snap-fitting or riveting, or the first unlocking member 42 and the first locking member 41 can be integrally formed. This application does not limit this.

[0045] In this embodiment, the first locking member 41 is connected to one end of the first unlocking member 42 and is coaxial with the rotation axis of the first adapter 311, thus making the structure very compact.

[0046] It is understood that the specific structure of the first locking component 40 is not limited to the above description. As long as the first locking component 40 can lock the first column 31 so that the first column 31 will not rotate relative to the first shelf 10 and the second shelf 20, it is acceptable.

[0047] Please see Figure 1 , Figures 8 to 12The second column 32 is rotatably connected to the first shelf 10 via a second adapter 321. One end of the second adapter 321 is rotatably connected to the first shelf 10, and the other end is fixedly connected to the second column 32. The locking mechanism includes a second locking component 50 located at the connection between the second column 32 and the first shelf 10. The second locking component 50 includes a second locking member 51, a second unlocking member 52, a second elastic member 53, and a third elastic member 54. The second locking member 51 is horizontally movable on the first shelf 10, and the second unlocking member 52 is vertically movable on the first shelf 10. The side wall of the second unlocking member 52 is provided with a guide groove 521 that slopes downward toward the second adapter 321. The second locking member 51 is provided with a guide post 511, which passes through the guide groove 521 and can move along the guide groove 521. The second elastic member 53 abuts against the second locking member 51 and the first shelf 10, and the third elastic member 54 abuts against the second unlocking member 52 and the first shelf 10. In its natural state, the second unlocking member 52 moves to its highest position under the elastic force of the third elastic member 54, the guide post 511 is located at the lower end of the guide groove 521, the second locking member 51 compresses the second elastic member 53, and one end of the second locking member 51 locks the second adapter 321. When the second unlocking member 52 moves downward to its lowest position, the second unlocking member 52 compresses the third elastic member 54, and the second locking member 51 moves away from the second adapter 321 under the elastic force of the second elastic member 53, thereby releasing the lock on the second adapter 321, and the guide post 511 is located at the upper end of the guide groove 521. With this configuration, in its natural state, the second locking member 51 is locked. At this time, the second adapter 321 cannot rotate relative to the first shelf 10. Since the second adapter 321 and the second column 32 are fixedly connected, the second column 32 also cannot rotate relative to the first shelf 10. Therefore, locking the second adapter 321 with the second locking member 51 keeps the second column 32 in a vertical position, thus ensuring the tool cart remains stably in the unfolded state. When the tool cart needs to be folded, when the first column 31 is folded to a horizontal or near-horizontal position, pressing down the second unlocking member 52 moves the second locking member 51 to the unlocked position, allowing the second adapter 321 and the second column 32 to rotate relative to the first shelf 10. This rotates the second column 32 and the second shelf 20 from a vertical to a horizontal position, with the second column 32 positioned on the upward-facing side of the second shelf 20. Figure 4 As shown.

[0048] In this embodiment, the second unlocking member 52 is configured as a button that can move up and down. Part of the second unlocking member 52 protrudes from the top surface of the second shelf 20, making it convenient for the user to press the second unlocking member 52. The user can press the second unlocking member 52 by stepping on it, and this application does not limit this. The second locking member 51 is disposed inside the first shelf 10. The second locking member 51 can be configured as Z-shaped, with a guide post 511 at one end and the other end used to lock the second adapter 321. In this embodiment, the second adapter 321 is provided with a lock hole 3211. The second locking member 51 locks the second adapter 321 by inserting its end into the lock hole 3211, thereby restricting the rotation of the second adapter 321 and the second post 32 relative to the first shelf 10. The second locking member 51 has a cavity 512, and the first shelf 10 has a limiting part 13 extending into the cavity 512. The second elastic member 53 is a second spring and is disposed within the cavity 512. The two ends of the second elastic member 53 abut against the side wall of the cavity 512 and the limiting part 13 of the second locking member 51, respectively, so that the second locking member 51 has a tendency to move away from the second adapter 321. The third elastic member 54 is a third spring and abuts between the unlocking member and the first shelf 10.

[0049] It is understood that the specific structure of the second locking component 50 is not limited to the above description. As long as the second locking component 50 can lock the second column 32 so that the second column 32 will not rotate relative to the first shelf 10, it is acceptable.

[0050] In summary, the tool cart of this application can lock the first column 31 in a vertical state (i.e., the unfolded state) by setting the first locking component 40, and can lock the second column 32 in a vertical state (i.e., the unfolded state) by setting the second locking component 50, so that the tool cart can be stably maintained in such a state. Figure 1 The unfolded state shown can also be stably maintained as... Figure 3 The tool cart is shown in a semi-folded, semi-unfolded state. It is understandable that when the tool cart is in this state... Figure 1 In the unfolded state shown, both the first shelf 10 and the second shelf 20 can be used as storage surfaces; when the tool cart is in the unfolded state as shown... Figure 3 When in the semi-folded and semi-unfolded state shown, the tool cart can be used as a regular flatbed cart, with the first storage platform 10 serving as the storage surface and the second column 32 serving as the cart's pull rod.

[0051] Please see Figure 13One or more storage slots 12 can be provided on the first shelf 10 and the second shelf 20, thus facilitating the placement of items on the first shelf 10 and the second shelf 20. In this embodiment, the first shelf 10 has one storage slot 12, and the second shelf 20 has one large storage slot 12 and three small storage slots 12. The three small storage slots 12 are arranged on one side of the large storage slot 12, so that the small storage slots 12 do not affect the capacity of the large storage slot 12, and can also hold some small items. The storage slots 12 can also be arranged in various ways, and this application does not limit them.

[0052] Please see Figures 13 to 15 Furthermore, a groove 22 is provided at the edge of the second shelf 20. In this way, a hook 90 can be placed in the groove 22, so that items can be hung on the hook 90, thereby increasing the storage capacity of the tool cart.

[0053] In one embodiment, the groove 22 has its opening facing upwards, allowing for the placement of hooks 90 with an inverted U-shaped attachment portion 91, which is very convenient to use. In another embodiment, as shown in the figure, the groove 22 has a first groove portion 221 and a second groove portion 222 arranged opposite to each other. The opening of the first groove portion 221 faces upwards, and the opening of the second groove portion 222 faces downwards. This allows for the placement of both inverted U-shaped and C-shaped hooks 90 with attachment portions 91, making it even more convenient to use. In yet another embodiment, the groove 22 extends through the upper and lower end faces of the second shelf 20, allowing for the placement of both inverted U-shaped and C-shaped hooks 90 with attachment portions 91, making it even more convenient to use.

[0054] Furthermore, the groove 22 extends along the side of the second shelf 20, and one end penetrates the side wall of the second shelf 20 along the extension direction of the groove 22. In this way, the hook 90 can be hung in the groove 22 from the end of the groove 22 that penetrates the side wall of the second shelf 20. The groove 22 of this embodiment is particularly suitable for hanging hooks 90 with a C-shaped hanging part 91.

[0055] like Figure 13 As shown, in this embodiment, the slot 22 extends along the side of the second shelf 20, thus providing a longer hanging space for multiple hooks 90 and items. However, this is not a limitation; in other embodiments, there may be multiple slots 22, spaced apart along the side of the second shelf 20. In this way, the slot 22 can also hold multiple hooks 90 and items, making it very convenient to use.

[0056] Furthermore, the groove 22 is provided with reinforcing ribs 223 to enhance the structural strength of the groove 22 and extend its service life.

[0057] It is understood that the bottom of the first storage platform 10 is provided with wheels 60 to facilitate the movement of the tool cart for transporting goods. The wheels 60 can be configured as omnidirectional wheels, thereby making the movement of the tool cart more flexible. In this embodiment, the bottom of the first storage platform 10 is provided with four wheels 60, which can stably support the tool cart. Of course, in other embodiments, the number of wheels 60 can also be 6 or 8, or other numbers, and this application does not limit this.
