[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0063] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.

[0064] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0065] Referring to FIG. 1 , the present application provides a tool cart 100 comprising a main frame 10, a tray 20, a first wheel 30, and a second wheel 40. The tray 20 is mounted on the main frame 10 for placing items. The first wheel 30 and the second wheel 40 are mounted on the main frame 10 and spaced apart. The diameter of the first wheel 30 is larger than the diameter of the second wheel 40.

[0066] The tray 20 is used to store external storage items, and the main frame 10 serves as the main body of the tool cart 100, providing support and load-bearing. It is understood that the tool cart 100 relies on the friction between the first and second wheels 30, 40 and the ground to achieve relative movement. The first wheel 30 has a relatively large diameter, resulting in a relatively large contact area with the ground, and thus relatively high friction with the ground. By providing the first wheel 30 with a relatively large diameter, the tool cart 100 can move smoothly even on grass, hills, and sandy ground. Furthermore, the second wheel 40 has a relatively small diameter, allowing the tool cart 100 to steer flexibly even on complex terrain. In other words, by providing the first wheel 30 with a relatively large diameter in conjunction with the second wheel 40 with a relatively small diameter, the tool cart 100 can navigate smoothly and flexibly even on complex terrain.

[0067] In one embodiment, the first wheel 30 is configured as a pneumatic wheel, and the size of the first wheel 30 is 16 inches.

[0068] In one embodiment, the bottom of the first wheel 30 is flush with the bottom of the second wheel 40. In this way, the first wheel 30 and the second wheel 40 can support the main frame 10 more stably.

[0069] 8 to 11 , further, in order to keep the bottoms of the first wheel 30 and the second wheel 40 flush, in one embodiment, the tool cart 100 further includes a padding plate 91 , and the second wheel 40 is mounted on the bottom of the main frame 10 via the padding plate 91 .

[0070] Referring to Figure 8 , to further facilitate the installation and steering of the second wheel 40, the tool cart 100 also includes a connecting leg 92. One end of the connecting leg 92 is used to mount the second wheel 40, and the other end is provided with an adapter plate 921 for connecting to the elevated plate 91. The adapter plate 921 is a plate-like structure that fits snugly against the elevated plate 91 and is then fixedly connected to the elevated plate 91 using screws or the like. Typically, to ensure the secure connection between the adapter plate 921 and the elevated plate 91, a screw is used at each of the four corners of the adapter plate 921 to connect to the elevated plate 91.

[0071] However, the installation of screws is extremely cumbersome and laborious, and too many screws are easily missed and lost. Therefore, referring to Figures 12 to 14, further, in order to reduce the use of screws, the difficulty and time-consuming of connecting the adapter plate 921 and the padding plate 91 are reduced. In one embodiment, the tool cart 100 also includes a connecting folding plate 93, which is installed on the padding plate 91 and forms at least one card slot 94 with a side opening 941 between the connecting folding plate 93 and the plate surface of the padding plate 91. The edge of the adapter plate 921 can be clamped in the card slot 94 through the side opening 941. In this way, part of the adapter plate 921 can be clamped by the card slot 94, effectively reducing the number of screws used. At the same time, the bottom wall of the card slot 94 can play a supporting role and play a pre-installation role, which is convenient for installing screws.

[0072] Referring to Figure 14, further, the connecting folding plate 93 and the plate surface of the padding plate 91 form three slots 94 connected in sequence, and the connection shape of the three slots 94 is U-shaped. The adapter plate 921 can be inserted from the U-shaped mouth, so that the three edges of the adapter plate 921 are respectively inserted into the three slots 94. In this way, the firmness of the connection between the adapter plate 921 and the padding plate 91 can be ensured by one or two screws.

[0073] It is understandable that in other embodiments, one or two slots 94 may be provided, as long as the slots 94 cooperate with the screws to stably and firmly connect the adapter legs 92 and the raising plate 91 .

[0074] In one embodiment, the second wheel 40 is configured as a universal wheel. The universal wheel is more flexible in steering, so that the user can push or pull the tool cart 100 to turn with less effort.

[0075] There are multiple trays 20, arranged vertically. One tray 20 is mounted on the bottom of the main frame 10 and forms the bottom wall of the main frame 10. The first wheel 30 and the second wheel 40 are respectively connected to the bottom wall of the main frame 10. The multiple trays 20 provide the tool cart 100 with more independent storage space. Furthermore, the trays 20 located at the bottom of the main frame 10 provide more space for the first and second wheels 30, 40, allowing for flexible adjustment of their installation positions.

[0076] Optionally, as shown in FIG. 3 , there are two trays 20 , one of which is mounted on the top of the main frame 10 and the other is mounted on the bottom of the main frame 10 .

[0077] 15 and 16 , in one embodiment, a leakage hole 21 is provided at at least one bottom corner of the tray 20 . The leakage hole 21 is used to prevent water from accumulating in the tray 20 .

[0078] Optionally, there are two first wheels 30, and the two first wheels 30 are spaced apart from each other, and there are two second wheels 40, and the two second wheels 40 are spaced apart from each other.

[0079] In one embodiment, as shown in Figure 3 , the tool cart further includes a connecting rod 41 connected to the bottom wall of the main frame 10. Both ends of the connecting rod 41 extend out of the main frame 10. Two first wheels 30 are rotatably connected to both ends of the connecting rod 41. By extending the ends of the connecting rod 41 out of the main frame 10, both first wheels 30 are located outside the main frame 10. This prevents the main frame 10 from being partially lifted when mounted on the bottom wall, which could lead to unstable support for the main frame 10.

[0080] 8 to 11 , in some embodiments, a stopper 141 is provided at the end of the connecting rod 41 . The stopper 141 is used to prevent the first wheel 30 from being separated from the end of the connecting rod 41 .

[0081] 8 and 9 , in one embodiment, the stopper 141 is a locking pin inserted into the end of the connecting rod 41. It is understood that in other embodiments, as shown in FIG10 and FIG11 , the stopper 141 may also be a self-locking nut rotatably connected to the end of the connecting rod 41.

[0082] As shown in FIG3 , the tool cart 100 further includes a drawer 50 , which is slidably connected to the main frame 10 and can extend out of the main frame 10 along a first direction X. This makes it convenient for a user to take items from the drawer 50 .

[0083] Alternatively, the number of drawers 50 can be set to be single, and the single drawer 50 is located below the tray 20, and the bottom of the tray 20 can cover the opening of the drawer 50. In this way, when the drawer 50 is closed, the items in the drawer 50 will not fall out. Of course, the drawer 50 can also be provided in multiple numbers, and multiple drawers 50 can be arranged up and down.

[0084] 3 and 4 , the tool cart 100 further includes a locking member 60 for locking the drawer 50 to the main frame 10. In this way, the drawer 50 will not open automatically due to external force or shaking of the tool cart 100.

[0085] Optionally, a locking member 60 is mounted on one of the main frame 10 and the drawer 50, and a locking hole 11 is defined in the other of the main frame 10 and the drawer 50. The locking member 60 can be inserted into the locking hole 11 along a second direction Y, which is perpendicular to the first direction X. When the locking member 60 is inserted into the locking hole 11 along the second direction Y, the locking member 60 can stop the drawer 50, thereby preventing the drawer 50 from extending from the main frame 10 along the first direction X.

[0086] 3 to 7 , the locking member 60 will be described below by taking the example of the lock hole 11 being opened in the main frame 10 and the locking member 60 being installed on the drawer 50 .

[0087] The locking member 60 includes an outer shell 61 and a locking pin 62. The outer shell 61 is fixedly connected to the drawer 50, and the locking pin 62 is movably connected to the outer shell 61. At least a portion of the locking pin 62 extends out of the outer shell 61 and can be inserted into the lock hole 11. In this embodiment, the locking pin 62 is configured to engage with the lock hole 11, thereby forming a stop for the drawer 50. The outer shell 61 serves to mount the locking pin 62 to the drawer 50. Specifically, the outer shell 61 can be fixedly connected to the outer shell 61 by screws.

[0088] Furthermore, the outer shell 61 defines a channel 611, through which a locking pin 62 is movably disposed. One end of the locking pin 62 can extend from the channel 611 and be inserted into the lock hole 11; alternatively, one end of the locking pin 62 can be retracted into the channel 611 and disengaged from the lock hole 11. When the locking pin 62 extends from the channel 611 and is inserted into the lock hole 11, the locking member 60 locks the drawer 50 and the main frame 10 together. When the locking pin 62 retracts into the channel 611 and disengages the lock hole 11, the drawer 50 and the main frame 10 are unlocked. The channel 611 guides the locking pin 62, allowing it to slide more smoothly relative to the outer shell 61.

[0089] The end of the lock pin 62 away from the lock hole 11 is formed with a first limiting step 621, and the first limiting step 621 is stopped by the outer shell 61. By providing the first limiting step 621, the lock pin 62 can be prevented from detaching from the outer shell 61 and falling into the lock hole 11.

[0090] Specifically, a shift block 623 is provided at the end of the lock pin 62 facing away from the lock hole 11. The shift block 623 protrudes axially from the lock pin 62, forming a first stop step 621 between the shift block 623 and the lock pin 62. This allows the user to easily pull the shift block 623 away from the lock hole 11, thereby unlocking the drawer 50 from the main frame 10. The shift block 623 and the lock pin 62 are detachably connected.

[0091] The locking member 60 also includes an elastic return member 63. A second step 612 is provided within the channel 611. One end of the elastic return member 63 is connected to the second step 612, and the other end elastically acts on the end of the locking pin 62 near the lock hole 11. In this way, the elastic return member 63 can exert a force on the locking pin 62 directed toward the lock hole 11, thereby keeping the end of the locking pin 62 near the lock hole 11 inserted in the lock hole 11, thereby maintaining the drawer 50 and the main frame 10 locked together. Furthermore, the elastic return member 63 exerts a force on the locking pin 62 directed toward the lock hole 11, which also forces the shift block 623 to firmly abut against the outer shell 61, thereby maintaining a secure connection between the locking pin 62 and the outer shell 61.

[0092] The lock pin 62 is provided with a guide surface 622. As the drawer 50 slides into the main frame 10, the guide surface 622 can respond to external force and push the lock pin 62 in a direction away from the lock hole 11 until the lock pin 62 is inserted into the lock hole 11. Specifically, during the process of closing the drawer 50, the main frame 10 compresses the elastic return member 63 by squeezing the guide surface 622, thereby squeezing the lock pin 62 toward the channel 611. As the guide surface 622 moves to the lock hole 11, the force applied by the main frame 10 on the guide surface 622 disappears, and the elastic return member 63 applies a force to the lock pin 62 directed toward the lock hole 11, driving the lock pin 62 to insert into the lock hole 11. In this way, as the drawer 50 slides into the main frame 10, the lock member 60 can automatically lock the drawer 50 and the main frame 10 together.

[0093] 2 , a plurality of hooks 12 are provided on the main frame 10. The hooks 12 are used to hang items, such as tool kits, tool bags, etc.

[0094] In one embodiment, the main frame 10 includes a plurality of detachably connected sub-frames 103, which are spliced ​​to form a rectangular main frame 10 or a cube-shaped main frame 10. In other words, the main frame 10 is configured as a rectangular frame or a cube frame.

[0095] 2 and 15 , each of the plurality of sub-frames 103 of the main frame 10 includes four vertical brackets 13 , and each vertical bracket 13 is provided with at least one hook 12 . This allows items to be hung on all sides of the main frame 10 .

[0096] Furthermore, the hook 12 is detachably connected to the main frame 10 .

[0097] Optionally, a mounting hole 14 is provided on the main frame 10, and the hook 12 is a "Z"-shaped bent piece, with one end of the hook 12 abutting against and being threadedly connected to the inner wall of the main frame 10, and the other end extending out of the mounting hole 14. The provision of the mounting hole 14 facilitates the removal of the hook 12.

[0098] Furthermore, the multiple sub-frames 103 may also include transverse brackets (not shown) for connecting the vertical brackets 13. The number of transverse brackets can be adjusted as needed to ensure the overall stability of the tool cart 100. It will be appreciated that, as shown in Figures 15 and 27, the vertical brackets 13 may also be connected via other accessories of the tool cart 100, such as the side walls of the tray 20.

[0099] As shown in FIG. 3 , the tool cart 100 further includes a load-bearing accessory, which is installed on a side surface of the main frame 10 .

[0100] The load-bearing accessories include a load-bearing bracket 70, which is installed on the side of the main frame 10 and has a plurality of sockets 71 formed on the load-bearing bracket 70 for inserting items to be stored. The load-bearing bracket 70 expands the storage space of the tool cart 100.

[0101] Optionally, the tool cart includes two load-bearing brackets 70 , wherein one load-bearing bracket 70 is installed on the top of the main frame 10 , and the other load-bearing bracket 70 is installed on the bottom of the main frame 10 .

[0102] 15 , it can be understood that the load-bearing bracket 70 can be specifically configured as a tool hanging bucket 701 , an electric tool rack 702 or other brackets with a storage function.

[0103] Furthermore, the tool cart 100 is further provided with a reinforcement mounting plate 98, the two ends of which are connected to two vertical brackets 13 arranged side by side and spaced apart along the first direction X. The load-bearing bracket 70 is connected to both the main frame 10 and the reinforcement mounting plate 98 to further ensure installation stability.

[0104] As shown in Figures 1 and 2, the tool cart 100 further includes a push-pull member 80, which is connected to the main frame 10. The push-pull member 80 is used for a user to hold and push and pull the tool cart 100.

[0105] Optionally, the push-pull member 80 is configured as a crossbar, with both ends of the crossbar connected to the main frame 10, and the middle of the crossbar is spaced apart from the main frame 10 to facilitate user grip. It is understandable that the push-pull member 80 can also be configured as an armrest with one end suspended.

[0106] Referring to Figures 17 to 21, in one embodiment, the tool cart 100 further includes a workbench 95, which is movably mounted on the main frame 10. The workbench 95 has a working state and a storage state. In the working state, the workbench 95 moves to the top of the main frame 10, and the back surface 952 of the workbench 95 is parallel to and abuts against the top surface of the main frame 10.
