Description

Technical Field

[0001] The present application relates to the technical field of tool storage, and in particular to a tool cart. Background Art

[0002] With the popularity of outdoor activities, the market demand for tool carts is also increasing. Tool carts are usually used to assist in storing items to assist in various outdoor activities. However, the storage space of tool carts is relatively limited. In addition, due to the complex terrain of outdoor roads, such as grass, mountains or sandy roads, it is difficult for tool carts to travel on the above road conditions. Utility Model Content

[0003] Based on this, it is necessary to provide a tool cart that is convenient for storing items and can be more stable and flexible on grass, mountains or sand.

[0004] A tool cart comprises a main frame, a tray, a first wheel and a second wheel. The tray is installed on the main frame. The first wheel and the second wheel are respectively installed on the bottom of the main frame and are arranged at intervals. The diameter of the first wheel is greater than that of the second wheel.

[0005] In one embodiment, the second wheel is configured as a universal wheel. It is understandable that such a configuration makes the tool cart more flexible in steering, thereby making it easier for the user to push and pull the tool cart to turn.

[0006] In one embodiment, there are multiple trays, wherein one tray is installed at the bottom of the main frame and constitutes the bottom wall of the main frame, and the first wheel and the second wheel are respectively connected to the bottom wall of the main frame. It can be understood that, in this arrangement, multiple trays enable the tool cart to have more independent storage spaces. In addition, the tray located at the bottom of the main frame can also provide a larger installation space for the first wheel and the second wheel, so that the installation positions of the first wheel and the second wheel can be flexibly adjusted.

[0007] In one embodiment, the tool cart further comprises a connecting rod, the connecting rod is connected to the bottom wall of the main frame, and the two ends of the connecting rod extend out of the main frame respectively, the number of the first wheels is two, and the two first wheels are located on both sides of the main frame and are rotatably connected to the two ends of the connecting rod respectively. It can be understood that such an arrangement enables the two first wheels to be located on the outside of the main frame, thereby avoiding the problem of partially lifting the main frame when the main frame is installed on the bottom wall of the main frame, thereby causing the main frame to be unstable.

[0008] In one embodiment, the tool cart further comprises a drawer, which is slidably connected to the main frame, and the drawer can extend out of the main frame along a first direction X. It can be understood that such a configuration facilitates users to take and place items from the drawer.

[0009] In one embodiment, the tool cart further comprises a locking member, which is used to lock the drawer to the main frame. It is understandable that, with such arrangement, the drawer will not open automatically due to external force or shaking of the tool cart.

[0010] In one embodiment, the locking member is installed on one of the main frame and the drawer, and a locking hole is provided on the other of the main frame and the drawer, and the locking member can be inserted into the locking hole along the second direction Y; the second direction Y is perpendicular to the first direction X. It can be understood that, in such a configuration, when the locking member is inserted into the locking hole along the second direction Y, the locking member can form a stop for the drawer, so that the drawer cannot extend from the main frame along the first direction X.

[0011] In one embodiment, a plurality of hooks are provided on the main frame. It is understandable that, in this arrangement, the hooks are used to hang items, such as tool kits, tool bags, etc., so as to expand the storage space of the tool cart.

[0012] In one embodiment, the tool cart further comprises a load-bearing bracket, which is mounted on the side of the main frame and has a plurality of insertion holes, which are used to insert the items to be stored. It can be understood that, in this arrangement, the items to be stored are inserted into the load-bearing bracket through the insertion holes, making it more convenient for users to take and put.

[0013] In one embodiment, the surface of the tool trolley has an anti-ultraviolet coating. It is understandable that, in this way, when the tool trolley is used outdoors, the anti-ultraviolet coating can prevent the tool trolley from being damaged by ultraviolet radiation.

[0014] Compared with the prior art, the tool cart provided by the present application has a tray for placing external storage items, and the main frame is the main part of the tool cart, which is used for supporting and bearing. It can be understood that the tool cart relies on the friction between the first wheel and the second wheel and the ground to achieve relative movement to the ground. The first wheel has a relatively large diameter, so its contact area with the ground is relatively large, and thus the friction between it and the ground is also relatively large. By setting a first wheel with a relatively large diameter, the tool cart can also move smoothly on grass, mountains and sand. In addition, the diameter of the second wheel is relatively small, so the tool cart can also turn flexibly on complex terrain. That is, by setting a first wheel with a relatively large diameter to cooperate with a second wheel with a relatively small diameter, the tool cart can also travel smoothly and flexibly on complex terrain.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0025] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may 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 intermediate medium. Moreover, a first feature being “above”, “above” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those 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 related listed items.

[0029] See also Figure 1 The present application provides a tool cart 100, which includes 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, and the first wheel 30 and the second wheel 40 are respectively mounted on the main frame 10 and spaced apart, and the diameter of the first wheel 30 is greater than the diameter of the second wheel 40.

[0030] The tray 20 is used to place external storage items, and the main frame 10 is the main part of the tool cart 100, which is used for support and load bearing. It can be understood that the tool cart 100 relies on the friction between the first wheel 30 and the second wheel 40 and the ground to achieve relative movement on the ground. The first wheel 30 has a relatively large diameter, so its contact area with the ground is relatively large, and thus the friction between it and the ground is relatively large. By setting the first wheel 30 with a relatively large diameter, the tool cart 100 can also move smoothly on grass, mountains and sand. In addition, the diameter of the second wheel 40 is relatively small, so the tool cart 100 can also turn flexibly on complex terrain. That is, by setting the first wheel 30 with a relatively large diameter and the second wheel 40 with a relatively small diameter, the tool cart 100 can also travel smoothly and flexibly on complex terrain.

[0031] Preferably, the first wheel 30 is configured as a pneumatic wheel, and the size of the first wheel 30 is 16 inches.

[0032] Preferably, 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.

[0033] Preferably, 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.

[0034] There are multiple trays 20, and the multiple trays 20 are arranged up and down, wherein one tray 20 is installed at the bottom of the main frame 10 and constitutes 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. Multiple trays 20 allow the tool cart 100 to have more independent storage space. In addition, the tray 20 located at the bottom of the main frame 10 can also provide a larger installation space for the first wheel 30 and the second wheel 40, so that the installation position of the first wheel 30 and the second wheel 40 can be flexibly adjusted.

[0035] Alternatively, if Figure 3 As shown, there are two trays 20 , one of which is installed on the top of the main frame 10 , and the other tray 20 is installed on the bottom of the main frame 10 .

[0036] Optionally, the number of the first wheels 30 is two, and the two first wheels 30 are arranged at intervals from left to right, and the number of the second wheels 40 is also two, and the two second wheels 40 are arranged at intervals from left to right. The first wheels 30 and the second wheels 40 are arranged at intervals from front to back.

[0037] Preferably, if Figure 3The tool cart further includes a connecting rod 41, which is connected to the bottom wall of the main frame 10, and both ends of the connecting rod 41 extend out of the main frame 10, and there are two first wheels 30, which are rotatably connected to both ends of the connecting rod 41. By arranging the ends of the connecting rod 41 to extend out of the main frame 10, the two first wheels 30 are both located outside the main frame 10, thereby avoiding the problem of partially lifting the main frame 10 when the main frame 10 is installed on the bottom wall of the main frame 10, thereby causing the main frame 10 to be unstable.

[0038] like Figure 3 As shown, the tool cart 100 further includes a drawer 50 , which is slidably connected to the main frame 10 , and the drawer 50 can extend out of the main frame 10 along a first direction X. In this way, it is convenient for a user to take and place items from the drawer 50 .

[0039] Optionally, the number of drawers 50 can be set to be single, and a 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 set to be multiple, and multiple drawers 50 are arranged up and down.

[0040] like Figure 3 and Figure 4 As shown, the tool cart 100 further includes a locking member 60, which is used to lock the drawer 50 to the main frame 10. In this way, the drawer 50 will not open automatically due to the tool cart 100 being subjected to external force or shaking.

[0041] Optionally, the locking member 60 is installed on one of the main frame 10 and the drawer 50, and a locking hole 11 is opened on the other of the main frame 10 and the drawer 50, and the locking member 60 can be inserted into the locking hole 11 along the second direction Y; the second direction Y 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 form a stop for the drawer 50, so that the drawer 50 cannot extend from the main frame 10 along the first direction X.

[0042] See also Figures 3 to 7 The locking member 60 will be described below by taking the example that the lock hole 11 is opened in the main frame 10 and the locking member 60 is installed on the drawer 50 .

[0043] 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 locking hole 11. In this embodiment, the locking pin 62 is used to be plugged and matched with the locking hole 11, so as to form a stop for the drawer 50, and the outer shell 61 plays the role of installing the locking pin 62 on the drawer 50. Specifically, the outer shell 61 can be fixedly connected to the outer shell 61 by screws.

[0044] Furthermore, the outer shell 61 is provided with a channel 611, and the lock pin 62 is movably arranged in the channel 611, and one end of the lock pin 62 can extend out of the channel 611 and be inserted into the lock hole 11; or one end of the lock pin 62 can be retracted into the channel 611 and be separated from the lock hole 11. When the lock pin 62 extends out of the channel 611 and is inserted into the lock hole 11, the lock member 60 locks the drawer 50 and the main frame 10 together; when the lock pin 62 is retracted into the channel 611 and is separated from the lock hole 11, the drawer 50 and the main frame 10 are unlocked. The channel 611 can guide the lock pin 62, so that the lock pin 62 slides more smoothly relative to the outer shell 61.

[0045] 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.

[0046] Specifically, a shift block 623 is provided at one end of the lock pin 62 away from the lock hole 11. The shift block 623 protrudes from the lock pin 62 in the axial direction, and a first limiting step 621 is formed between the shift block 623 and the lock pin 62. In this way, it is convenient for the user to pull the shift block 623 in the direction away from the lock hole 11, so as to unlock the drawer 50 and the main frame 10. The shift block 623 and the lock pin 62 are detachably connected.

[0047] The locking member 60 further includes an elastic reset member 63. A second step 612 is provided inside the channel 611. One end of the elastic reset 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 reset member 63 can exert a force directed toward the lock hole 11 on the locking pin 62, so that the end of the locking pin 62 near the lock hole 11 remains inserted in the lock hole 11, that is, the drawer 50 and the main frame 10 remain locked together. In addition, the elastic reset member 63 exerts a force directed toward the lock hole 11 on the locking pin 62, and can also enable the shift block 623 to firmly abut against the outer shell 61, so that the locking pin 62 and the outer shell 61 remain firmly connected.

[0048] 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 to move in a direction away from the lock hole 11 until the lock pin 62 is inserted into the lock hole 11. Specifically, in the process of closing the drawer 50, the main frame 10 compresses the elastic reset 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 to the guide surface 622 disappears, and the elastic reset member 63 applies a force directed to the lock hole 11 to the lock pin 62, and drives the lock pin 62 to be inserted into the lock hole 11. In this way, when 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.

[0049] See also Figure 2 , a plurality of hooks 12 are provided on the main frame 10. The hooks 12 are used to hang articles, such as tool kits, tool bags, etc.

[0050] Preferably, the main frame 10 is configured as a rectangular parallelepiped frame or a cube frame. Each main frame 10 includes four brackets 13, and each bracket 13 is equipped with at least one hook 12. In this way, objects can be hung on all four sides of the main frame 10.

[0051] Furthermore, the hook 12 is detachably connected to the main frame 10 .

[0052] Optionally, a mounting hole 14 is provided on the main frame 10, and the hook 12 is a "Z"-shaped bent piece, one end of the hook 12 is attached to and threadedly connected to the inner wall of the main frame 10, and the other end extends out of the mounting hole 14 through the mounting hole 14. By providing the mounting hole 14, the hook 12 is convenient to disassemble.

[0053] like Figure 3 As shown, the tool cart 100 further includes a load-bearing bracket 70, which is mounted on the side of the main frame 10 and has a plurality of insertion holes 71, which are used to insert items to be stored. The load-bearing bracket 70 expands the storage space of the tool cart 100.

[0054] 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 .

[0055] like Figure 1 and Figure 2 As shown, 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.

[0056] Optionally, the push-pull member 80 is configured as a crossbar, both ends of which are connected to the main frame 10, and the middle of the crossbar is spaced from the main frame 10 to facilitate user gripping. It is understandable that the push-pull member 80 can also be configured as a handrail with one end suspended.

[0057] The surface of the tool cart 100 has an anti-ultraviolet coating, which can prevent the tool cart 100 from being damaged by ultraviolet radiation.

[0058] Optionally, pure polyester powder coating is sprayed on the surface of the tool cart 100 to form an anti-ultraviolet coating.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
