Description

[0001] This application is a divisional application of application number 202210588703.5, application date May 27, 2022, entitled "Module connection structure, external component, storage box and storage box assembly". Technical Field

[0002] This invention relates to the field of item storage technology, and in particular to an external component and storage box. Background Technology

[0003] Conventional storage boxes are all independent structures. To increase storage capacity, multiple boxes need to be stacked. When stacking boxes, the only way to prevent them from sliding is through friction between their contact surfaces. For users who need to stack multiple boxes, if there is no interlocking mechanism between the boxes, the stacked boxes may lose balance, creating a safety hazard. This is especially true when moving multiple stacked boxes simultaneously; shifts in the center of gravity or vibrations caused by uneven surfaces can easily cause the boxes to slip.

[0004] To avoid the above problems, the conventional solution is to add ropes and other accessories to help secure multiple boxes. However, this solution not only increases the cost, but also requires untying the ropes and other accessories before taking out the items from the storage box, making it inconvenient to use.

[0005] In addition to stacking storage boxes to increase their storage capacity, external attachments can also be installed on the outside of the storage boxes to carry other items. However, regular storage boxes do not have this feature.

[0006] In view of this, it is indeed necessary to provide an external component, a storage box, and a storage box component to solve this problem. Summary of the Invention

[0007] The purpose of this invention is to provide an external component that enhances the storage capacity of a storage box.

[0008] This invention provides an external attachment component, including a first external attachment having a first connecting portion and a second external attachment having a second connecting portion; The first connecting portion includes a first locking buckle and a second locking buckle pulsatorically connected to the first locking buckle. The first locking buckle has a first limiting member, and the second locking buckle has a first position locked to the second connecting portion and a second position unlocked from the second connecting portion. The second locking buckle includes a transmission member connected to the first locking buckle, a second limiting member connected to the transmission member, and an elastic member. The second limiting member can be locked to the second connecting portion. The transmission member is provided with a connecting portion, and the elastic member is provided on the transmission member with one end abutting against the connecting portion and the other end abutting against the first external attachment. The elastic member is used to automatically keep the second locking buckle in the first position. The second connecting portion includes a first hook lockable to the first locking buckle and a second hook lockable to the second locking buckle. When the first limiting member and the second limiting member are in contact with the first hook and the second hook, the second locking buckle is driven to move from the first position to the second position until the first limiting member passes the first hook and the second limiting member passes the second hook. Under the action of the elastic member, the second locking buckle returns to the first position, and the second locking buckle drives the first locking buckle and the second connecting part to lock each other. Under the action of external force, the second locking buckle moves from the first position to the second position, and the second locking buckle drives the first locking buckle and the second connecting part to unlock each other.

[0009] Furthermore, the second locking buckle is a horizontal sliding buckle or a flipping buckle, which drives the first locking buckle to move horizontally or flip.

[0010] Furthermore, the second locking buckle is a flip-up buckle that causes the first locking buckle to flip and move. The second locking buckle and the first locking buckle are respectively located on opposite edges of the first external attachment.

[0011] Furthermore, the transmission component is made of a rigid or flexible material.

[0012] Furthermore, the second locking buckle also includes a plurality of the aforementioned transmission components and a pull rod capable of connecting the plurality of transmission components.

[0013] Furthermore, the second locking buckle also includes a link that can connect multiple levers.

[0014] Furthermore, one second locking buckle can cause multiple first locking buckles to lock and unlock with the second connecting part.

[0015] Furthermore, the first attachment also has an external connection part.

[0016] Furthermore, a limiting groove is also provided on the first connecting part, and the limiting groove is located between the first locking buckle and the second locking buckle.

[0017] Furthermore, the second connecting part is also provided with a limiting post that cooperates with the limiting groove, and the limiting post can be accommodated in the limiting groove.

[0018] Furthermore, the second accessory includes multiple second connecting parts with different unlocking directions.

[0019] The present invention also provides a storage box, wherein the storage box is provided with the above-mentioned external attachment, and the second external attachment is detachably mounted on the storage box body; when the first connecting part and the second connecting part are unlocked from each other, the first external attachment is separated from the storage box.

[0020] The present invention provides an external component and a storage box; the external component can enhance the storage capacity of the storage box, so that the storage capacity of the storage box is no longer limited to the inside of the box. Attached Figure Description

[0044] This invention provides a modular connection structure, an external component with the connection structure, a storage box, and a storage box assembly. The connection structure can be installed on the storage box, allowing adjacent storage boxes to lock together, thus facilitating the transportation of multiple storage boxes and enhancing their storage capacity. Simultaneously, the connection structure can also be used as an external component for the storage box, further enhancing its storage capacity. The storage box can be a toolbox, tool basket, transport box, transfer box, or other storage device.

[0045] [First Embodiment] Please refer to the following: Figures 1 to 5 This embodiment provides a module connection structure that can be disposed on a storage box 20. The connection structure includes at least one first connecting portion 1 located on one surface of the module and at least one second connecting portion 2 located on another surface of the module. The first connecting portion 1 and the second connecting portion 2 can cooperate and lock together. The storage box assembly includes multiple storage boxes 20. Adjacent storage boxes 20 can be locked together by the first connecting portion 1 and the second connecting portion 2. Adjacent storage boxes 20 can be vertically stacked or horizontally connected, thereby enhancing the storage capacity of the storage boxes 20. In other embodiments, the storage box assembly may include multiple first storage boxes and multiple second storage boxes that can be locked and unlocked with the first storage boxes. Each first storage box includes multiple first connecting portions 1 located on one surface and multiple second connecting portions 2 located on another surface. The multiple second storage boxes can be simultaneously locked onto one surface of a first storage box.

[0046] The module can be a storage box 20, with a first connecting part 1 disposed on the bottom of the storage box 20 and a second connecting part 2 disposed on the lid of the storage box. Specifically, the storage box 20 has a bottom 1a (i.e., the bottom of the box), two pairs of opposing sides 1c, and a top 1b (i.e., the lid of the box). The bottom 1a and the top 1b are arranged opposite each other, and the two pairs of opposing sides 1c are respectively connected to the periphery of the bottom 1a and the top 1b, forming a storage box body. Further, the top 1b is provided with a mounting groove 202, and the bottom 1a is provided with a mounting protrusion 201 that matches the contour of the mounting groove 202. The mounting protrusion 201 can be accommodated in the mounting groove 202. In this embodiment, the cooperation between the mounting protrusion 201 and the mounting groove 202 can not only realize the rapid positioning when two storage boxes 20 are stacked, but also limit the horizontal displacement between the two storage boxes 20. Both the mounting groove 202 and the mounting protrusion 201 have guide bevels on their edges, which facilitates the quick installation of the mounting protrusion 201 into the mounting groove 202.

[0047] The first connecting part 1 is located on the bottom 1a. It includes a first locking buckle 11 and a second locking buckle 12 that is pulsatorically connected to the first locking buckle 11. The second locking buckle 12 can drive the first locking buckle 11 to move, so that the second locking buckle 12 and the first locking buckle 11 can lock and unlock each other with the second connecting part 2 at the same time, thereby enabling the interlocking function between two adjacent storage boxes 20, which is convenient and quick.

[0048] The first locking buckle 11 has a first limiting member 111 protruding in a direction away from the second locking buckle 12. The first locking buckle 11 is correspondingly disposed with a first hook 21 on the top 1b of the second connecting part 2. The first hook 21 can form a first slot 211, so that the first limiting member 111 can extend into the first slot 211. Specifically, when two storage boxes 20 are stacked, the first limiting member 111 of one storage box 20 is embedded in the first slot 211 of the other storage box 20, thereby limiting the vertical displacement between the two storage boxes 20, thereby realizing the interlocking between the two storage boxes 20. In other embodiments, the locking of the first limiting member 111 and the first slot 211 can also simultaneously limit the vertical and horizontal displacement between the two storage boxes 20. In this embodiment, the first hook 21 is located at one end of the top 1b, and the first slot 211 is formed on the first hook 21, but the structure forming the first slot 211 is not limited to this. The first limiting member 111 is provided with a first guide slope 112, and the first hook 21 is provided with a second guide slope 212, thereby facilitating the sliding of the first limiting member 111 into the first slot 211. In this embodiment, the number of first locking buckles 11 corresponds one-to-one with the number of second locking buckles 12; in other embodiments, multiple first locking buckles 11 may also be provided.

[0049] The second locking buckle 12 is a horizontal sliding buckle that drives the first locking buckle 11 to move horizontally. Specifically, one second locking buckle 12 can drive at least one first locking buckle 11 to lock and unlock with the second connecting part 2, thereby conveniently and quickly realizing the interlocking function between two storage boxes 20, facilitating the stacking and quick separation of multiple storage boxes 20. In this embodiment, the number of first locking buckles 11 corresponds one-to-one with the number of second locking buckles 12; in other embodiments, one second locking buckle 12 can also drive multiple first locking buckles 11 to move simultaneously. When one second locking buckle 12 drives multiple first locking buckles 11 to move, since the multiple first locking buckles 11 move horizontally, the multiple first locking buckles 11 are not limited to being located at the edge of the storage box 20, but can be located in the middle of the storage box 20, making the locking between the storage boxes 20 more secure and reliable. The second locking buckle 12 includes a transmission part 121, a second limiting member 122 connected to the transmission part 121, and an elastic member 123. The second locking buckle 12 has a first position that is locked to the second connecting part 2 and a second position that is unlocked from the second connecting part 2. When the second locking buckle 12 is in the first position, the second locking buckle 12 drives the first locking buckle 11 to lock to the second connecting part 2. When the second locking buckle 12 is in the second position, the second locking buckle 12 drives the first locking buckle 11 to unlock from the second connecting part 2.

[0050] The transmission member 121 is made of rigid or flexible material and can be configured as an elongated structure, disposed on the bottom 1a and extending along the length of the bottom 1a. In other embodiments, the transmission member 121 can also be a rigid or flexible, bulky, or curved structure. The transmission member 121 is located between the first locking buckle 11 and the second locking buckle 12, so that the second locking buckle 12 can control the movement of the first locking buckle 11 through the transmission member 121. Further, the transmission member 121 is provided with a connecting portion 121a, the diameter of which is larger than the diameter of the transmission member 121, so that one end of the elastic member 123 abuts against the connecting portion 121a. In this embodiment, there are two transmission members 121 arranged side by side, and the first locking buckle 11 is fixed on the connecting portion 121a of the two transmission members 121, thereby enhancing the stability of the sliding of the first locking buckle 11. In other embodiments, multiple transmission members 121 can be provided; the transmission structure 121 can also be a gear transmission structure, a belt transmission structure, etc.

[0051] The second limiting member 122 is a rod-shaped structure that can be locked to the second connecting part 2. Specifically, the second limiting member 122 is located at one end of the two transmission members 121 and is connected between the two transmission members 121. It is correspondingly arranged with the second hook 22 on the top 1b of the second connecting part 2, and the second hook 22 can form a second slot 221, so that the second limiting member 122 can extend into the second slot 221. Specifically, when the two storage boxes 20 are stacked, the second limiting member 122 of one storage box 20 is embedded in the second slot 221 of the other storage box 20, thereby further restricting the vertical displacement between the two storage boxes 20. The two storage boxes 20 have two fixing points, front and rear, for better fixing effect. In other embodiments, the locking of the second limiting member 122 and the second slot 221 can also simultaneously restrict the vertical and horizontal displacement between the two storage boxes 20. In this embodiment, the second hook 22 is disposed at one end of the top 1b, and the second slot 221 is formed on the second hook 22, but the structure of the second slot 221 is not limited thereto. The second hook 22 is provided with a third guide slope 222, so as to facilitate the second limiting member 122 to slide into the second slot 221.

[0052] One end of the elastic element 123 abuts against the first connecting portion 1, and the other end abuts against the storage box 20. In this embodiment, one end of the elastic element 123 abuts against the connecting portion 121a on the transmission member 121, and the other end abuts against the storage box 20. In other embodiments, one end of the elastic element 123 may also abut against the first locking buckle 11. Specifically, the elastic element 123 can cause the transmission member 121 of the second locking buckle 12 to automatically be in the first position so that the first locking buckle 11 is automatically kept in the locked state. When the transmission member 121 is moved to the second position by an external force, the transmission member 121 drives the first locking buckle 11 into the unlocked state. The elastic element 123 is, for example, a spring. The elastic element 123 is sleeved on the transmission member 121 and one end abuts against the connecting portion 121a. The other end of the elastic element 123 abuts against the storage box 20. Under the elastic force of the elastic element 123, the second locking buckle 12 is forced to automatically fix in the first position, thereby realizing the automatic locking of the first locking buckle 11 and the second locking buckle 12.

[0053] Furthermore, the second locking buckle 12 also includes a pull rod 124 that can connect to multiple transmission members 121. In this embodiment, the pull rod 214 is located at the end of two transmission members 121 away from the connecting portion 121a and is connected to the two transmission members 121. The pull rod 214 is located on the outside of the side portion 1c and is used to allow the user to pull the transmission member 121 to unlock the first locking buckle 11. In other embodiments, multiple pull rods 214 may be provided.

[0054] Furthermore, the second locking buckle 12 also includes a connecting rod 215 that can connect multiple pull rods 214. In this embodiment, the connecting rod 215 is disposed between the pull rods 214 of the two second locking buckles 12 and can drive the multiple pull rods 214 to move. When there are two second locking buckles 12 and they are arranged side by side on the bottom 1a, the two pull rods 214 are connected to each other through the connecting rod 215. The side portion 1c is provided with a relief groove corresponding to the position of the connecting rod 215. Pulling the connecting rod 215 outward can move the transmission member 121, so that pulling the connecting rod 215 can simultaneously control the movement of the two second locking buckles 12. In this embodiment, the side portion 1c is also provided with a carrying handle 203. The carrying handle 203 is disposed on the same side as the connecting rod 215, which makes it convenient for the user to lift the storage box 20 while unlocking. In other embodiments, the connecting rod 215 can also be used as the carrying handle 203, simplifying the design and realizing multiple uses of the connecting rod 215.

[0055] like Figure 6 and Figure 7 As shown, the upper storage box 20 is pressed vertically against the lower storage box 20. The first limiting member 111 and the second limiting member 122 at the bottom 1a of the upper storage box contact each other with the first hook 21 and the second hook 22 at the top 1b of the lower storage box, thereby converting the vertical pressing force into a horizontal driving force. This drives the second locking buckle 12 at the bottom 1a of the upper storage box to move from the first position to the second position until the first limiting member 111 passes the first hook 21 and enters the first slot 211 area, and the second limiting member 122 passes the second hook 22 and enters the second slot 221 area. Under the action of the elastic member 123, the second locking buckle 12 automatically returns to the first position, realizing the automatic interlocking of the two storage boxes 20.

[0056] When it is necessary to unlock the upper and lower storage boxes 20, pull the lever 214 outward by hand. Under the action of external force, the transmission component 121 of the second locking buckle 12 moves horizontally, causing the transmission component 121 to move from the first position to the second position. The first limiting component 111 of the upper storage box 20 is unlocked and disengaged from the first slot 211 of the lower storage box 20, and the second limiting component 122 is disengaged from the second slot 221. At this time, the elastic component 123 is compressed, and the upper storage box 20 is pulled up, so that the upper and lower storage boxes 20 can be separated.

[0057] The beneficial effects of the storage box 20 provided in this embodiment are: the two storage boxes 20 are locked to each other through the first connecting part 1 and the second connecting part 2. The first connecting part 1 includes a first locking buckle 11 and a second locking buckle 12 that is pulsatorically connected to the first locking buckle 11. The second locking buckle 12 can simultaneously drive multiple first locking buckles 11 to move, thereby conveniently and quickly realizing the interlocking function between the two storage boxes 20, and facilitating the stacking and quick separation of adjacent two storage boxes 20.

[0058] [Second Embodiment] Please refer to the following: Figures 8 to 12 The storage box 20 in this embodiment differs from that in the first embodiment in that: the second locking buckle 12 is a flip buckle, which drives the first locking buckle 11 to move horizontally; the connecting part 121a of the transmission member 121 is provided at one end of the transmission member 121 near the second locking buckle 12, so that the elastic member 123 is also provided near the second locking buckle 12; at the same time, the opening direction of the first hook 21 and the second hook 22 is changed accordingly according to the unlocking direction of the second locking buckle 12. It can be understood that the opening direction is the unlocking direction of the second locking buckle 12.

[0059] Specifically, the second limiting member 122 includes a rotating body 122a, a limiting buckle 122b, a rotating shaft 122c, a rotating cover 122d, and a handle groove 122e. One end of the rotating body 122a is rotatably connected to the side 1c of the storage box 20 via the rotating shaft 122c, and the other end of the rotating body 122a is provided with a limiting buckle 122b. The rotating cover 122d is fixed on the rotating body 122a. The upper end of the rotating cover 122d is located above the rotating shaft 122c and is provided with a handle groove 122e. The lower end of the rotating cover 122d is located below the rotating shaft 122c and is divided into two legs that abut against the connecting parts 121a of the two transmission members 121 respectively.

[0060] like Figure 13 and Figure 14 As shown, the upper storage box 20 is pressed vertically against the lower storage box 20. The first limiting member 111 and the second limiting member 122 at the bottom 1a of the upper storage box contact each other with the first hook 21 and the second hook 22 at the top 1b of the lower storage box, thereby converting the vertical pressing force into a horizontal driving force. This drives the second locking buckle 12 at the bottom 1a of the upper storage box to move from the first position to the second position until the first limiting member 111 passes the first hook 21 and enters the first slot 211 area, and the second limiting member 122 passes the second hook 22 and enters the second slot 221 area. Under the action of the elastic member 123, the second locking buckle 12 automatically returns to the first position, realizing the automatic interlocking of the two storage boxes 20.

[0061] When it is necessary to unlock the upper and lower storage boxes 20, manually turn the rotating cover 122d of the second locking buckle 12 to make the limiting buckle 122b rotate around the rotating shaft 122c. The lower end of the rotating cover 122d presses against the transmission component 121, causing the transmission component 121 to move from the first position to the second position. The first limiting component 111 of the upper storage box 20 unlocks and disengages from the first slot 211 of the lower storage box 20, and the limiting buckle 122b disengages from the second slot 221. At this time, pull up the upper storage box 20 to separate the upper and lower storage boxes 20.

[0062] Other structures of the storage box 20 in this embodiment can be referred to in the first embodiment described above, and will not be repeated here.

[0063] [Third Embodiment] Please refer to the following: Figures 15 to 17 The difference between the storage box 20 in this embodiment and the second embodiment is that the first locking buckle 11 is also a flip-type buckle, and the second locking buckle 12 drives the first locking buckle 11 to flip and move. In this embodiment, since both the first locking buckle 11 and the second locking buckle 12 are flip-type buckles, both the first locking buckle 11 and the second locking buckle 12 need to be set on the edge of the storage box 20 so as not to affect the flip-type movement of the locking buckle.

[0064] Specifically, the first limiting member 111 includes a rotating body 111a, a limiting buckle 111b, and a rotating shaft 111c. One end of the rotating body 111a is rotatably connected to the side 1c of the storage box 20 via the rotating shaft 111c, and the other end of the rotating body 111a is provided with the limiting buckle 111b. At the same time, the first guide slope 112 of the first limiting member 111 is provided on the limiting buckle 111b.

[0065] like Figure 18 As shown, the upper storage box 20 is pressed vertically against the lower storage box 20. The first limiting member 111 and the second limiting member 122 at the bottom 1a of the upper storage box contact each other with the first hook 21 and the second hook 22 at the top 1b of the lower storage box, thereby converting the vertical pressing force into a horizontal driving force. This drives the second locking buckle 12 at the bottom 1a of the upper storage box to move from the first position to the second position until the first limiting member 111 passes the first hook 21 and enters the first slot 211 area, and the second limiting member 122 passes the second hook 22 and enters the second slot 221 area. Under the action of the elastic member 123, the second locking buckle 12 automatically returns to the first position, realizing the automatic interlocking of the two storage boxes 20.

[0066] When it is necessary to unlock the upper and lower storage boxes 20, manually turn the rotating cover 122d of the second locking buckle 12 to make the limiting buckle 122b rotate around the rotating shaft 122c. The lower end of the rotating cover 122d presses against the transmission component 121, causing the transmission component 121 to move from the first position to the second position. Under the action of the second locking buckle 12, the first limiting component 111 of the upper storage box 20 causes the limiting buckle 111b to rotate around the rotating shaft 111c and unlock and disengage from the first slot 211 of the lower storage box 20. The limiting buckle 122b of the second locking buckle 12 disengages from the second slot 221. At this time, pull up the upper storage box 20 to separate the upper and lower storage boxes 20.

[0067] Other structures of the storage box 20 in this embodiment can be referred to in the first and second embodiments described above, and will not be repeated here.

[0068] [Fourth Embodiment] Please refer to the following: Figures 19 to 20The difference between the storage box 20 in this embodiment and the first embodiment is that the connecting structure can also be used as an external attachment component 30 for the storage box 20. The storage box assembly includes multiple storage boxes 20 equipped with external attachment components 30. Two adjacent storage boxes 20 can be locked together by the first connecting part 1 and the second connecting part 2, thereby enhancing the storage capacity of the storage box 20. At the same time, each storage box 20 can carry other items by being equipped with external attachment components 30, thereby further enhancing the storage capacity of the storage box 20.

[0069] Specifically, the add-on component 30 includes a first add-on 31 and a second add-on 32 that can be locked and unlocked with the first add-on 31. For example... Figure 20 As shown, the first external attachment 31 is provided with a first connecting part 1 and an external connection part 311. The first connecting part 1 of the first external attachment 31 can be unlocked and locked with the second external attachment 32; the external connection part 311 can be connected to other external tools, thereby enabling the first external attachment 31 to carry other tools and further enhance the storage capacity of the storage box 20. In this embodiment, the external connection part 311 has a hook-shaped structure for hanging other tools; in other embodiments, the external connection part 311 may also have other shapes, which can not only carry things but also increase the function of the storage box 20. For example, the external connection part 311 can be used as a bottle opener. In addition, the first connecting part 1 of the first external attachment 31 is also provided with a limiting groove 13, which is located between the first locking buckle 11 and the second locking buckle 12.

[0070] like Figure 19 As shown, the second external attachment 32 is provided with a second connecting part 2. The second external attachment 32 includes at least one second connecting part 2, which is detachably mounted on the toolbox body. The external part 311 can be connected to the toolbox body by bolts, clips, etc. Simultaneously, multiple second external attachments 32 can be installed on the toolbox body. In other embodiments, the second external attachment 32 can also be integrally formed with the toolbox body. When the first connecting part 1 of the first external attachment 31 and the second connecting part 2 of the second external attachment 32 are unlocked, the first external attachment 31 is separated from the storage box 20; when the first connecting part 1 of the first external attachment 31 and the second connecting part 2 of the second external attachment 32 are locked, both the first external attachment 31 and the second external attachment 32 are connected to the storage box 20. In this embodiment, the second external attachment 32 is provided with multiple second connecting parts 2, and the multiple second connecting parts 2 have different unlocking directions, which are opposite; therefore, multiple second connecting parts 2 can be locked with multiple first connecting parts 1, thereby carrying multiple other tools. In addition, the second connecting part 2 of the second external attachment 32 is also provided with a limiting post 23 that cooperates with the limiting groove 13. The limiting post 23 can be accommodated in the limiting groove 13, so that the first external attachment 31 and the second external attachment 32 are more secure when locked together, which can meet the requirements of carrying heavier tools.
