Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of article storage, in particular to a connecting structure of modules, an external hanging assembly, a storage box and a storage box assembly. BACKGROUND

[0002] Conventional storage boxes are independent structures, and in order to enhance the storage capacity of the storage box, multiple storage boxes need to be stacked. If the box bodies are to be stacked and placed, the friction force of the contact surface between the upper and lower box bodies can only be relied on to prevent relative sliding. For users who need to stack and place multiple storage boxes, if the interlocking function is not provided between the two box bodies, the box body may lose balance after being stacked and placed for multiple layers, thereby causing safety hazards. Especially when multiple stacked box bodies need to be moved at the same time, the center of gravity is offset during the moving process or the road surface is uneven, which produces vibration and easily causes the box body to slide off.

[0003] To avoid the above problems, the conventional solution is to increase accessories such as ropes to assist in fixing multiple box bodies, but this solution not only increases additional costs, but also requires the accessories such as ropes to be untied before the items in the storage box can be taken out, which is not convenient to use.

First Embodiment

[0056] Please refer to Figures 1 to 5The present embodiment provides a connecting structure of a module, which can be arranged on the storage box 20. The connecting structure comprises at least one first connecting part 1 arranged on one surface of the module and at least one second connecting part 2 arranged on another surface of the module, and the first connecting part 1 and the second connecting part 2 can be locked with each other. The storage box assembly comprises a plurality of storage boxes 20, and two adjacent storage boxes 20 can be locked with each other through the first connecting part 1 and the second connecting part 2, and the two adjacent storage boxes 20 can be connected vertically or left and right, thereby enhancing the storage capacity of the storage box 20. In other embodiments, the storage box assembly can comprise a plurality of first storage boxes and a plurality of second storage boxes which can be locked and unlocked with the first storage boxes, and each first storage box comprises a plurality of first connecting parts 1 arranged on one surface thereof and a plurality of second connecting parts 2 arranged on another surface thereof, and a plurality of second storage boxes can be locked on one surface of one first storage box at the same time.

[0057] The module can be the storage box 20, the first connecting part 1 is arranged on the bottom of the storage box 20, and the second connecting part 2 is arranged on the cover of the storage box. Specifically, the storage box 20 has a bottom 1a (i.e., the bottom of the box), two pairs of opposite side portions 1c and a top 1b (i.e., the cover of the box), the bottom 1a is arranged opposite to the top 1b, the two pairs of opposite side portions 1c are connected around the bottom 1a and the top 1b respectively, and the bottom 1a and the two pairs of opposite side portions 1c surround to form a storage box body. Further, the top 1b is provided with a mounting groove 202, the bottom 1a is provided with a mounting protrusion 201 matched with the profile of the mounting groove 202, and the mounting protrusion 201 can be accommodated in the mounting groove 202; in the present embodiment, the cooperation between the mounting protrusion 201 and the mounting groove 202 not only can realize quick positioning when two storage boxes 20 are stacked, but also can limit the horizontal displacement between the two storage boxes 20. The edges of the mounting groove 202 and the mounting protrusion 201 are provided with guide inclined surfaces, thereby facilitating quick installation of the mounting protrusion 201 in the mounting groove 202.

[0058] The first connecting part 1 is arranged on the bottom 1a, which comprises a first locking buckle 11 and a second locking buckle 12 in driving connection with 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 are locked and unlocked with the second connecting part 2 at the same time, thereby realizing the interlocking function between the two adjacent storage boxes 20, which is convenient and fast.

[0059] The first locking buckle 11 has a first limiting piece 111 protruding towards the direction away from the second locking buckle 12. The first locking buckle 11 is arranged in correspondence with the first clamping hook 21 on the top 1b of the second connecting part 2. The first clamping hook 21 can form a first clamping groove 211, so that the first limiting piece 111 can extend into the first clamping groove 211. Specifically, when the two storage boxes 20 are arranged in a stacked manner, the first limiting piece 111 of one of the storage boxes 20 is embedded into the first clamping groove 211 of the other storage box 20, thereby limiting the vertical displacement between the two storage boxes 20, and achieving the interlocking between the two storage boxes 20. In other embodiments, the locking of the first limiting piece 111 and the first clamping groove 211 can also simultaneously limit the vertical and horizontal displacement between the two storage boxes 20. In the present embodiment, the first clamping hook 21 is located at one end of the top 1b, and the first clamping groove 211 is formed on the first clamping hook 21, but the structure forming the first clamping groove 211 is not limited thereto. The first limiting piece 111 is provided with a first guide inclined surface 112, and the first clamping hook 21 is provided with a second guide inclined surface 212, thereby facilitating the sliding of the first limiting piece 111 into the first clamping groove 211. In the present embodiment, the number of first locking buckles 11 corresponds to the number of second locking buckles 12; in other embodiments, a plurality of first locking buckles 11 can also be arranged.

[0060] The second locking buckle 12 is a horizontal sliding buckle, and 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 be locked and unlocked with the second connecting part 2, thereby conveniently and quickly achieving the interlocking function between the two storage boxes 20, and facilitating the stacking and quick separation of a plurality of storage boxes 20. In the present embodiment, the number of first locking buckles 11 corresponds to the number of second locking buckles 12; in other embodiments, one second locking buckle 12 can also drive a plurality of first locking buckles 11 to move. When one second locking buckle 12 drives a plurality of first locking buckles 11 to move, since the plurality of first locking buckles 11 move horizontally, the plurality of first locking buckles 11 are not limited to being arranged at the edge position of the storage box 20, but can be arranged at the middle position of the storage box 20, so that the locking between the storage boxes 20 is more firm and reliable. The second locking buckle 12 includes a transmission part 121, a second limiting piece 122 connected with the transmission part 121, and an elastic piece 123. The second locking buckle 12 has a first position for interlocking with the second connecting part 2 and a second position for inter-unlocking with the second connecting part 2. When the second locking buckle 12 is located at the first position, the second locking buckle 12 drives the first locking buckle 11 to be locked with the second connecting part 2. When the second locking buckle 12 is located at the second position, the second locking buckle 12 drives the first locking buckle 11 to be unlocked with the second connecting part 2.

[0061] The transmission member 121 is made of rigid or soft material, which can be in an elongated structure and arranged on the bottom 1a and extend along the length direction of the bottom 1a. In other embodiments, the transmission member 121 can also be in a thick, curved structure made of rigid or soft material. 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 the connecting portion 121a is larger than that of the transmission member 121, so that one end of the elastic member 123 abuts against the connecting portion 121a. In this embodiment, the number of transmission members 121 is two and arranged side by side, and the first locking buckle 11 is fixed on the connecting portions 121a of the two transmission members 121, so as to enhance the stability of the sliding of the first locking buckle 11. In other embodiments, a plurality of transmission members 121 can be provided; the transmission structure 121 can also be a gear transmission structure, a belt transmission structure, etc.

[0062] The second limiting member 122 is in a rod structure, which can be locked with the second connecting portion 2; specifically, the second limiting member 122 is located at one end of the two transmission members 121, and the second limiting member 122 is connected between the two transmission members 121, which is correspondingly arranged with the second hook 22 on the top 1b of the second connecting portion 2, and the second hook 22 can form a second clamping groove 221, so that the second limiting member 122 can extend into the second clamping groove 221. Specifically, when the two storage boxes 20 are stacked, the second limiting member 122 of one of the storage boxes 20 is embedded into the second clamping groove 221 of the other storage box 20, so as to further limit the vertical displacement between the two storage boxes 20, and the two storage boxes 20 have two front and back fixed points therebetween, and the fixing effect is better. In other embodiments, the locking of the second limiting member 122 and the second clamping groove 221 can also simultaneously limit the vertical and horizontal displacement between the two storage boxes 20. In this embodiment, the second hook 22 is arranged at one end of the top 1b, and the second clamping groove 221 is formed on the second hook 22, but the structure forming the second clamping groove 221 is not limited thereto. The second hook 22 is provided with a third guide inclined surface 222, so as to facilitate the sliding of the second limiting member 122 into the second clamping groove 221.

[0063] One end of the elastic member 123 is in abutment with the first connecting portion 1, and the other end is in abutment with the storage box 20. In the present embodiment, one end of the elastic member 123 is in abutment with the connecting portion 121a on the transmission member 121, and the other end is in abutment with the storage box 20. In other embodiments, one end of the elastic member 123 can also be in abutment with the first locking buckle 11. Specifically, the elastic member 123 can automatically position the transmission member 121 of the second locking buckle 12 at the first position to automatically keep the first locking buckle 11 in the locked state, and when the transmission member 121 is moved to the second position under the action of an external force, the transmission member 121 drives the first locking buckle 11 to enter the unlocked state. The elastic member 123, for example, a spring, is sleeved on the transmission member 121 and one end is in abutment with the connecting portion 121a, and the other end is in abutment on the storage box 20, and under the action of the elastic force of the elastic member 123, the second locking buckle 12 is forced to be automatically fixed at the first position, thereby realizing automatic locking of the first locking buckle 11 and the second locking buckle 12.

[0064] Further, the second locking buckle 12 further comprises a pull rod 124 connectable to a plurality of transmission members 121. In the present embodiment, the pull rod 214 is provided at one end of the two transmission members 121 away from the connecting portion 121a and connected to the two transmission members 121. The pull rod 214 is located outside the side portion 1c, which is used for the user to pull the transmission member 121 to unlock the first locking buckle 11. In other embodiments, a plurality of pull rods 214 can be provided.

[0065] Further, the second locking buckle 12 further comprises a connecting rod 215 connectable to a plurality of pull rods 214. In the present embodiment, the connecting rod 215 is provided between the two pull rods 214 of the second locking buckle 12 and can drive the plurality of pull rods 214 to move; when the number of second locking buckles 12 is two and arranged side by side on the bottom portion 1a, the two pull rods 214 are connected to each other through the connecting rod 215. The side portion 1c is provided with a avoiding slot corresponding to the position of the connecting rod 215, and the connecting rod 215 can be moved to move the transmission member 121, so that the connecting rod 215 can control the movement of the two second locking buckles 12 at the same time. In the present embodiment, the side portion 1c is also provided with a carrying portion 203. The carrying portion 203 is provided on the same side as the connecting rod 215, which facilitates the user to carry the storage box 20 while unlocking. In other embodiments, the connecting rod 215 can also be used as the carrying portion 203, which simplifies the design and realizes multiple purposes of the connecting rod 215.

[0066] As Figure 6 and Figure 7As shown, the upper storage box 20 is pressed in the vertical direction towards the lower storage box 20, the first limiting piece 111 and the second limiting piece 122 of the upper storage box bottom 1a are in contact with the first clamping hook 21 and the second clamping hook 22 of the lower storage box top 1b, thereby converting the extrusion force in the vertical direction into driving force in the horizontal direction, driving the second locking buckle 12 of the upper storage box bottom 1a to move from the first position to the second position, until the first limiting piece 111 passes through the first clamping hook 21 into the first clamping groove 211 area, and the second limiting piece 122 passes through the second clamping hook 22 into the second clamping groove 221 area, the second locking buckle 12 automatically returns to the first position under the action of the elastic piece 123, realizing the automatic interlocking of the two storage boxes 20.

[0067] When it is necessary to unlock the upper and lower two storage boxes 20, the pull rod 214 is pulled outward by hand, and under the action of the external force, the transmission piece 121 of the second locking buckle 12 moves in the horizontal direction to make the transmission piece 121 move from the first position to the second position, the first limiting piece 111 of the upper storage box 20 is unlocked and separated from the first clamping groove 211 of the lower storage box 20, and the second limiting piece 122 is separated from the second clamping groove 221, at this time, the elastic piece 123 is compressed, and the upper storage box 20 is pulled up, so that the upper and lower two storage boxes 20 can be separated.

[0068] The beneficial effects of the storage box 20 provided in the embodiment are that the two storage boxes 20 are locked by the first connecting part 1 and the second connecting part 2, the first connecting part 1 includes the first locking buckle 11 and the second locking buckle 12 in transmission connection with 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 placing and quick separation between the adjacent two storage boxes 20.

[0069]

Second embodiment

[0070] Please see Figures 8 to 12 The difference between the storage box 20 of the embodiment and the first embodiment is that the second locking buckle 12 is a flip buckle and drives the first locking buckle 11 to move horizontally, the connecting part 121a of the transmission piece 121 is arranged at one end of the transmission piece 121 close to the second locking buckle 12, so that the elastic piece 123 is also arranged close to the second locking buckle 12, and at the same time, the opening direction of the first clamping hook 21 and the second clamping hook 22 is changed 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.

[0071] Specifically, the second limiting member 122 comprises a rotating body 122a, a limiting buckle 122b, a rotating shaft 122c, a rotating cover 122d and a buckle hand slot 122e. One end of the rotating body 122a is rotationally connected to the side portion 1c of the storage box 20 through the rotating shaft 122c, and the other end of the rotating body 122a is provided with the limiting buckle 122b. The rotating cover 122d is fixedly arranged on the rotating body 122a. The upper end of the rotating cover 122d is located above the rotating shaft 122c and is provided with the buckle hand slot 122e. The lower end of the rotating cover 122d is located below the rotating shaft 122c and is divided into two branches to abut against the connecting portions 121a of the two transmission members 121, respectively.

[0072] As shown in Figure 13 and Figure 14 , the upper storage box 20 is pressed in the vertical direction towards the lower storage box 20. The first limiting member 111 of the upper storage box bottom 1a and the second limiting member 122 are in contact with the first clamping hook 21 and the second clamping hook 22 of the lower storage box top 1b, respectively. Thus, the extrusion force in the up-down direction is converted into driving force in the horizontal direction, which drives the second locking buckle 12 of the upper storage box bottom 1a to move from the first position to the second position, until the first limiting member 111 passes the first clamping hook 21 and enters the first clamping slot 211, and the second limiting member 122 passes the second clamping hook 22 and enters the second clamping slot 221. The second locking buckle 12 automatically returns to the first position under the action of the elastic member 123, thereby realizing the automatic interlocking of the two storage boxes 20.

[0073] When it is needed to unlock the two storage boxes 20, the rotating cover 122d of the second locking buckle 12 is pried by hand to rotate the limiting buckle 122b around the rotating shaft 122c. The lower end of the rotating cover 122d abuts against the transmission member 121 to drive the transmission member 121 to move from the first position to the second position. The first limiting member 111 of the upper storage box 20 is unlocked and separated from the first clamping slot 211 of the lower storage box 20. The limiting buckle 122b is separated from the second clamping slot 221. At this time, the upper storage box 20 is pulled up, and the two storage boxes 20 can be separated.

[0074] The other structures of the storage box 20 of the present embodiment can refer to the first embodiment described above, and will not be described herein.

[0075]

Third Embodiment

[0076] Please refer to Figures 15 to 17 , the difference between the storage box 20 of the present embodiment and the second embodiment is that the first locking buckle 11 is also a flip buckle, and the second locking buckle 12 drives the first locking buckle 11 to move in a flip manner. In the present embodiment, since the first locking buckle 11 and the second locking buckle 12 are both flip buckles, the first locking buckle 11 and the second locking buckle 12 are both arranged at the edge of the storage box 20 to not affect the flip movement of the locking buckle.

[0077] 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 rotationally connected to the side portion 1c of the storage box 20 through the rotating shaft 111c, and the other end of the rotating body 111a is provided with the limiting buckle 111b. Meanwhile, the first guide inclined surface 112 of the first limiting member 111 is arranged on the limiting buckle 111b.

[0078] As shown in Figure 18 the upper storage box 20 is pressed towards the lower storage box 20 in the vertical direction, the first limiting member 111 and the second limiting member 122 of the upper storage box bottom portion 1a are in contact with the first clamping hook 21 and the second clamping hook 22 of the lower storage box top portion 1b, so as to convert the extrusion force in the up-down direction into driving force in the horizontal direction, and drive the second locking buckle 12 of the upper storage box bottom portion 1a to move from the first position to the second position, until the first limiting member 111 passes the first clamping hook 21 and enters the first clamping groove 211 region, and the second limiting member 122 passes the second clamping hook 22 and enters the second clamping groove 221 region, and the second locking buckle 12 automatically returns to the first position under the action of the elastic member 123, so as to realize the automatic interlocking of the two storage boxes 20.

Fourth Embodiment

[0082] Please refer to Figures 19 to 20 The difference between the storage box 20 of the present embodiment and the first embodiment is that the connecting structure can also be used as the external hanging component 30 of the storage box 20. The storage box assembly includes a plurality of storage boxes 20 provided with the external hanging component 30, and adjacent two storage boxes 20 can be locked through the first connecting portion 1 and the second connecting portion 2, so as to enhance the storage capacity of the storage box 20; meanwhile, each storage box 20 can carry other articles by setting the external hanging component 30, so as to further enhance the storage capacity of the storage box 20.

[0083] Specifically, the external plug-in assembly 30 includes a first external plug-in 31 and a second external plug-in 32 that can be locked and unlocked with the first external plug-in 31. Figure 20 As shown, the first external attachment 31 is provided with a first connecting portion 1 and an external portion 311. The first connecting portion 1 of the first external attachment 31 can be unlocked and locked with the second external attachment 32; the external portion 311 can be connected to other external tools, so that the first external attachment 31 can carry other tools, further enhancing the storage capacity of the storage box 20. In this embodiment, the external portion 311 is a hook-shaped structure for hanging other tools; in other embodiments, the external portion 311 can also be in other shapes, which can not only carry things but also increase the functionality of the storage box 20. For example, the external portion 311 can be used as a bottle opener. In addition, a limiting groove 13 is also provided on the first connecting portion 1 of the first external attachment 31. The limiting groove 13 is located between the first locking buckle 11 and the second locking buckle 12.

[0084] like Figure 19 As shown, the second external attachment 32 is provided with a second connecting portion 2. The second external attachment 32 includes at least one second connecting portion 2, which is detachably mounted on the toolbox body. The external connection portion 311 can be connected to the toolbox body via bolts, clamps, or other means. Multiple second external attachments 32 can be mounted 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 portion 1 of the first external attachment 31 and the second connecting portion 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 portion 1 of the first external attachment 31 and the second connecting portion 2 of the second external attachment 32 are locked together, 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 portions 2, each of which has different unlocking directions, which are opposite to each other. Therefore, multiple second connecting portions 2 can be locked with multiple first connecting portions 1, thereby carrying multiple additional tools. In addition, a limiting column 23 that cooperates with the limiting groove 13 is also provided on the second connecting part 2 of the second external plug-in 32. The limiting column 23 can be accommodated in the limiting groove 13, so that the first external plug-in 31 and the second external plug-in 32 are more secure when locked with each other, which meets the requirements of carrying heavier tools.
