Abstract
Description
Technical Field
[0001] This utility model relates to the field of toolbox technology, and more specifically to a stackable toolbox. Background Technology
[0002] Toolboxes are practical pieces of equipment used to store various tools. When multiple toolboxes need to be stored or moved simultaneously, they are usually stacked. To achieve this, existing toolbox designs often incorporate grooves, protrusions, or latches at specific locations on the lid and bottom to ensure that multiple toolboxes can be stacked securely. This design approach is simple and straightforward, and can meet users' space utilization needs to a certain extent, especially when storing multiple toolboxes in limited space, effectively saving floor space.
[0003] However, this traditional stacking method has some significant problems in practical applications. First, the overall connection of the stacked toolboxes is not strong enough, and they are prone to loosening during transportation. Especially when encountering external vibrations or shaking, the top toolbox may wobble or even collapse due to a shift in the center of gravity. This not only threatens the safety of the tools inside the toolbox, potentially leading to tool damage or loss, but also poses potential safety risks to the user, increasing the possibility of accidental injury.

[0037] To avoid confusion with this utility model, some technical features known in the art have not been described.
[0038] like Figures 1-2 As shown, this utility model provides a stackable toolbox 100, including a box body 110, a box cover 120, and a buckle 130, a lever 140, a telescopic top rod assembly 150, a first elastic element 160, and a cover plate 170 disposed within the box cover 120. At least one hook 111 is provided on each of the left and right sides of the bottom of the box body 110 (two hooks on each side in this embodiment), with the hook openings of the hooks 111 facing forward. Furthermore, reinforcing ribs 1111 are provided between the hooks 111 and the sides of the box body 110, which enhance the structural strength of the hooks 111. The box cover 120 is disposed on the box body 110. Each of the left and right sides of the top of the lid 120 is provided with a latching element 130 and a lever 140. The upper end of the latching element 130 is provided with a slot 131, which communicates with the top surface of the lid 120 and is used to engage with the hook 111 at the bottom of another stackable toolbox 100 located above it. The lever 140 is connected to the front end of the latching element 130 through a telescopic top rod assembly 150. The front end of the first elastic member 160 is fixedly connected to the rear end of the latching element 130, and the rear end is fixedly connected to the lid 120. The cover plate 170 fixes the latching element 130, the lever 140, the telescopic top rod assembly 150, and the first elastic member 160 to the top of the lid 120.
[0039] By turning the lever 140 backward, the telescopic top rod assembly 150 can be extended, thereby pushing the latch 130 to move backward to complete the engagement with the hook 111 of the stackable toolbox 100 above it, and compressing the first elastic member 160 backward to give it elastic force; turning the lever 140 backward again can retract the telescopic top rod assembly 150, and the latch 130 moves forward under the elastic force of the first elastic member 160 to release the engagement between the upper and lower stackable toolboxes 100.
[0040] Please combine Figure 3 The left and right sides of the cover 120 each have a first mounting groove 121 for mounting the fastener 130. The top surface of the first mounting groove 121 communicates with the top surface of the cover 120, allowing the hook 111 of the upper toolbox 110 to connect with the fastener 130 through the top surface of the first mounting groove 121 when two toolboxes 100 are stacked. The left and right sides of the cover 120 each also have a through hole 122 for mounting a toggle switch 140. The through hole 122 can be located at the front end of the first mounting groove 121. A direction indicator 123 can be located near the through hole 122 to indicate the operating direction of the toggle switch 140 to the operator.
[0041] Please combine Figure 4On the left and right sides of the back of the cover 120, there are three mounting grooves: a first mounting groove 121 for mounting the buckle 130, a second mounting groove 124 for mounting the toggle 140 and the telescopic push rod assembly 150, and a third mounting groove 125 for mounting the first elastic element 160. The front and rear ends of the first mounting groove 121 communicate with the second mounting groove 124 and the third mounting groove 125, respectively. The second mounting groove 124 communicates with the through hole 122 so that the toggle part 141 of the toggle 140 can be exposed on the side of the cover 120. A first sliding groove 1241 is provided on the side wall of the second mounting groove 124 where the through hole 122 is located.
[0042] Please combine Figure 5 The cover plate 170 can be fixed to the back of the box cover 120 by bolts. It is provided with a guide rail 171 to guide the movement direction of the latching member 130, and a second slide groove 172 for mounting the toggle 140. The first slide groove 1241 and the second slide groove 172 restrict the sliding direction of the toggle 140. The toggle 140 includes a paddle portion 141 and a spring seat 142. The paddle portion 141 protrudes from the side of the box cover 120 for easy manual pressing operation by the operator. The spring seat 142 is located on the side opposite to the paddle portion 141 and is used to fix the second elastic element 152 of the telescopic push rod assembly 150.
[0043] like Figure 2 , Figure 6 and Figure 7 As shown, the telescopic push rod assembly 150 works similarly to a ballpoint pen, specifically including a first toothed post 151, a second elastic element 152, a guide sleeve 153, and a second toothed post 154. The first toothed post 151 is slidably installed inside the guide sleeve 153, and its rear end has multiple evenly distributed first protrusions 1511 formed radially outward. The rear end face of the first protrusion 1511 is serrated. The guide sleeve 153 is fixed on the box cover 120 and sleeved on the rear end of the first toothed post 151. The inner wall of the guide sleeve 153 is evenly spaced with first guide grooves 1531 and second guide grooves 1532. The number of first guide grooves 1531 and second guide grooves 1532 is the same, and the total number is equivalent to the number of first protrusions 1511. Both can accommodate the first protrusions 1511 and restrict the sliding direction of the first protrusions 1511. The first guide groove 1531 is a through groove, and the rear end of the second guide groove 1532 is provided with a stop slope. The second elastic element 152 is sleeved outside the first toothed post 151, with its front end fixed to the spring seat 142 of the toggle 140 and its rear end fixed to the front end of the guide sleeve 153. The front end of the second toothed post 154 is located inside the first toothed post 151, and a plurality of evenly distributed second protrusions 1541 are formed radially outward in the middle. The number of second protrusions 1541 is half that of the first protrusions 1511. The front end face of the second protrusions 1541 is a slope. The second protrusions 1541 can also be accommodated in the first guide groove 1531 and slide.
[0044] like Figure 8-10 The diagram shown illustrates the operation of the telescopic push rod assembly 150. In its initial state (e.g.) Figure 8 The second protrusion 1541 of the second toothed post 154 and the first protrusion 1511 of the first toothed post 151 are both located within the first guide groove 1531, and the second toothed post 154 is basically retracted within the guide sleeve 153. Please refer to... Figure 2 When you press the lever backward for the first time to 140 (as shown) Figure 9 and Figure 10 The first toothed post 151 in the first guide groove 1531 pushes against the second toothed post 154 and moves backward. Before it is completely removed from the first guide groove 1531, the serrated surface of the first protrusion 1511 and the inclined surface of the second protrusion 1541 are in line-surface contact, and the first elastic element is compressed to obtain elastic force. When the first toothed post 151 completely pushes the second toothed post 154 out of the first guide groove 1531, the second toothed post 154 loses the guiding constraint of the first guide groove 1531. Under the restoring force of the first elastic element 160, the inclined surface of the second protrusion 1541 slides along the serrated surface of the first protrusion 1511 until it is limited by the rear inclined surface of the second guide groove 1532. The rear end of the second toothed post 154 fully extends out of the guide sleeve 153, thereby pushing the buckle 130 to move backward, completing the locking with the hook 111 of the stackable toolbox 100 above; at the same time, the lever 140 resets under the elastic force of the second elastic element 152. When the lever 140 is pressed backward a second time (as shown in the image), the lever 140 returns to its original position. Figure 9 and Figure 8 The first toothed post 151 in the second guide groove 1532 slides out of the second guide groove 1532 and abuts against the second toothed post 154. The serrated surface of the first protrusion 1511 and the inclined surface of the second protrusion 1541 are in line-plane contact, so that the inclined surface of the second protrusion 1541 slides along the serrated surface of the first protrusion 1511 under the action of the elastic force of the first elastic member 160 until it slides into the first guide groove 1531. The rear end of the second toothed post 154 is basically retracted into the guide sleeve 153, returning to the initial state. The first elastic member 160 moves forward to reset under the action of the elastic force, thereby pushing the buckle 130 to move forward and complete the unlocking with the hook 111 of the stackable toolbox 100 above. At the same time, the toggle 140 resets under the action of the elastic force of the second elastic member 152.
[0045] It should be noted that in this embodiment, the hook opening of the latch 111 faces forward. In other embodiments, the hook opening of the latch 111 may face backward, in which case the components and their movement directions are reversed compared to this embodiment.
[0046] In summary, through the design of the toggle 140, the telescopic top rod assembly 150, and the first elastic element 160, this utility model enables the buckle 130 to move back and forth inside the box cover, thereby locking or unlocking the hook 111 of the stackable toolbox 100 on it.
[0047] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
