Description

Technical Field

[0001] The utility model relates to the technical field of tool boxes, in particular to a tool box. Background Art

[0002] Toolboxes are primarily used to store various tools. When multiple toolboxes need to be stored or transported together, they are typically stacked. Considering the stability of stacked toolboxes and preventing the upper and lower toolboxes from slipping during movement or transport, which could cause the toolboxes to fall and be damaged, those skilled in the art have designed a stackable magnetic toolbox (publication number CN220807330U). This design utilizes magnets on both end surfaces of the toolbox to magnetically connect the two toolboxes. This magnetic connection enhances the stability of the stack and effectively prevents slipping during transport.

[0003] However, in order to achieve the stability of the magnetic connection of the toolbox, it is necessary to ensure that the magnetic force of the magnet is strong enough, but this also makes it difficult to separate the toolboxes. Users need additional force to separate the magnetically stacked toolboxes, which may be laborious and inconvenient for some users. If the user uses improper force or attempts to forcibly separate the toolbox, it may cause the toolbox to fall, be damaged, or even cause personal injury. In addition, frequently applying large force to separate the toolbox may cause wear and tear on the toolbox itself and the tools stored inside. Utility Model Content

[0031] In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides a tool box 100, including a box body 110, a box cover 120, a magnetic device 130 and a ferromagnetic body 140, the box cover 120 is arranged on the box body 110; the magnetic device 130 is arranged on the bottom front side of the box body 110, and its working surface 130a (see Figure 4A and Figure 4B) is arranged on the bottom surface of the box body 110, and the status switch 131 is arranged on the front end surface of the box body 110; the ferromagnetic body 140 is arranged on the top surface of the box cover 120; the ferromagnetic body 140 can be a sheet or plate-shaped piece made of ferromagnetic materials such as iron plate, steel plate, etc. The magnetic attraction device 130 includes an open state and a closed state. When a tool box 100 needs to be fixed after being stacked with another tool box 100, the magnetic attraction device 130 of the tool box 100 located on the upper side is in the open state, and the magnetic attraction device 130 releases the magnetic field and magnetically attracts the ferromagnetic body 140 on the top surface of the tool box 100 below it; when the magnetic connection between the two tool boxes 100 needs to be released, the magnetic attraction device 130 of the tool box 100 located on the upper side is in the closed state, and the magnetic attraction device 130 turns off the magnetic field and releases the adsorption of the ferromagnetic body 140 below it.

[0034] Furthermore, since the magnetic device 130 and the ferromagnetic body 140 are only provided on the front side of the tool box 100, the rear side thereof becomes a weak side of magnetic attraction, and there is a problem that it is easy to separate after an accidental collision. Figure 2 As shown, this embodiment also provides a positioning and snap-fitting structure on the rear side of the toolbox 100. Specifically, a first positioning seat 111 is provided on the rear side of the bottom surface of the box body 110, and the bottom of the first positioning seat 111 extends rearward to form a snap-fitting portion 1111. A first positioning groove 121 is provided on the rear side of the top surface of the box cover 120, and a snap-fitting groove 1211 is provided within the first positioning groove 121. When the upper toolbox 100 is stacked on the lower toolbox 100, the snap-fitting portion 1111 of the first positioning seat 111 is first inserted into the snap-fitting groove 1211 to position and fix the rear side of the toolbox 100, and then the magnetic attraction device 130 on the front side is activated to achieve magnetic attraction of the front side.

[0035] It should be noted that in this embodiment, two first positioning seats 111 and first positioning grooves 121 are respectively provided on the left and right. This design is the optimal embodiment for achieving positioning and stable connection, but in other embodiments, only one first positioning seat 111 and first positioning groove 121 can be provided in the middle.

[0036] Furthermore, second positioning seats 112 may be provided at the left and right ends of the bottom front side of the box body 110, and second positioning slots 122 may be provided at the left and right ends of the top front side of the box cover 120. The second positioning seats 112 and the second positioning slots 122 are provided primarily to assist in achieving precise positioning of the front side of the toolbox 100. The connection of the front side of the toolbox 100 primarily relies on the magnetic attraction between the magnetic attraction device 130 and the ferromagnetic body 140. Therefore, the second positioning seats 112 do not need to be provided with a snap-fit ​​portion, and the second positioning slots 122 do not need to be provided with a snap-fit ​​slot.

[0037] It should be noted that, in this embodiment, two second positioning seats 112 and second positioning slots 122 are provided on the left and right sides respectively. However, in other embodiments, only one second positioning seat 112 and second positioning slot 122 may be provided on the left or right side.

[0038] Specifically, if Figure 3 As shown, the magnetic attraction device 130 includes a first magnetic yoke 133, a second magnetic yoke 134, a first separator 135, a second separator 136, a permanent magnet 132 and a state switch 131. The first magnetic yoke 133 and the second magnetic yoke 134 are arranged opposite to each other and spaced apart. The first separator 135 and the second separator 136 are arranged opposite to each other between the first magnetic yoke 133 and the second magnetic yoke 134. The first separator 135 and the second separator 136 are made of non-magnetic materials, such as copper, aluminum, plastic, wood, etc. The permanent magnet 135 is arranged in a receiving cavity surrounded by the first magnetic yoke 133, the second magnetic yoke 134, the first separator 135 and the second separator 136. The state switch 131 drives the permanent magnet 132 to rotate. Please refer to Figure 4A and Figure 4B When the two magnetic poles of the permanent magnet 132 are respectively opposite to the first magnetic yoke 133 and the second magnetic yoke 134, the magnetic attraction device 130 is in the open state; when the two magnetic poles of the permanent magnet 132 are respectively opposite to the first partition 135 and the second partition 136, the magnetic attraction device 130 is in the closed state.

[0039] Furthermore, a groove 1321 is provided on the permanent magnet 132 , and a protrusion 1311 is provided on the status switch 131 , and the protrusion 1311 is matched and engaged with the groove 1321 .

[0040] To further ensure the stability of the connection between the status switch 131 and the permanent magnet 132, a cover 138 can be placed on the status switch 131 to press the status switch 131 against the permanent magnet 132. Specifically, the cover 138 is fixed to the first and second partitions 135 and 136. A through hole 1381 is defined in the center of the cover 138 to expose the handle 1312 of the status switch 131. The cover 138 is labeled with the open and closed positions of the magnetic device 130, allowing the user to easily determine the current connection status between the workboxes and clearly identify the direction of switch operation.

[0041] It should be noted that the magnetic device 130 can also be other magnetic device structures already available on the market. For example, in this embodiment, the state switch 131 adopts a handle design, but this is not necessary. The state switch 131 can also be a switch button.

[0042] In addition, the setting positions of the magnetic device 130 and the ferromagnetic body 140 can be interchanged, that is, the ferromagnetic body 140 is set on the front side of the bottom of the box body 110; the magnetic device 130 is set on the front side of the top of the box cover, and its working surface 130a is set on the top surface of the box cover 110.

[0043] Example 2

[0044] like Figure 5 As shown, this embodiment provides a tool box 100, which differs from the first embodiment in the number and arrangement of the magnetic devices 130 and the ferromagnetic body 140, as well as the structural design of the positioning seat and the positioning groove.

[0045] First, this embodiment features two magnetic devices 130 and two ferromagnetic bodies 140. The magnetic devices 130 are positioned on the left and right sides of the bottom of the case 110, with their working surfaces 130a located on the bottom surface of the case 110 and the status switches 131 located on the left and right end surfaces of the case 110. The ferromagnetic bodies 140 are positioned on the left and right sides of the top surface of the case cover 120. This solution ensures symmetry in the left-right magnetic connection between the upper and lower toolboxes, further improving the stability of the connection.

[0046] In addition, the setting positions of the magnetic device 130 and the ferromagnetic body 140 can also be interchanged, that is, the ferromagnetic body 140 is set on the left and right sides of the bottom surface of the box body 110; the magnetic device 130 is set on the left and right sides of the top of the box cover, and its working surface 130a is set on the top surface of the box cover 110.

[0047] Second, since the present embodiment is provided with two left and right groups of magnetic devices 130 and ferromagnetic bodies 140, a symmetrical magnetic connection can be achieved on both sides. Therefore, it is not necessary to provide a first positioning seat 111 and a first positioning groove 121 with a snap-fit ​​structure on the rear side of the toolbox 100. It is only necessary to provide a second positioning seat 112 and a second positioning groove 122 on the front and rear sides of the toolbox 100 for auxiliary positioning.

[0048] Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
