Abstract
Description
Technical Field
[0001] This application relates to the field of enclosure technology, and in particular to a stackable enclosure, equipment cabinet and transport vehicle. Background Technology
[0002] Currently, most stackable crates on the market have positioning protrusions on the bottom of the crate and matching positioning grooves on another crate to facilitate stacking. However, this stacking method is not secure and is prone to tipping over upon impact. Furthermore, this type of stacking generally requires the crates to be stacked in the same direction, which is not conducive to rapid stacking. Summary of the Invention

The first coupling member is located on the other diagonal of the first side and is symmetrical about the center of the first side. The second coupling member is located on the other diagonal of the first side and is symmetrical about the center of the first side, wherein the center of the first side is the intersection of the two diagonals of the first side. The first coupling member includes n first protrusions, which surround n-1 first grooves. The second coupling member includes n+1 arc-shaped second protrusions, which surround n second grooves, wherein n≥1 and n is an integer. Both the first and second protrusions are arc-shaped protrusions. Along the X direction, the projection of the first protrusion is located in the second groove, wherein the X direction is perpendicular to the first and second sides.
[0007] Furthermore, the second side is provided with a pair of first coupling members and a pair of second coupling members, and the fourth side is provided with a pair of first coupling members and a pair of second coupling members; the pair of first coupling members on the second side is located on one diagonal of the second side and is centrally symmetrical about the center of the first side, and the pair of second coupling members on the second side is located on the other diagonal of the second side and is centrally symmetrical about the center of the second side, wherein the center of the second side is the intersection of the two diagonals of the second side; along the Y direction, the projection of the first protrusion on the second side is located in the second groove of the fourth side, and the projection of the first protrusion on the fourth side is located in the second groove of the second side, wherein the Y direction is a direction perpendicular to the second side and the fourth side.
[0008] Furthermore, the first coupling member and the second coupling member on the first side are respectively located at the four apex positions of the first side, and the first coupling member and the second coupling member on the second side are respectively located at the four apex positions of the second side. One of the first coupling members on the first side is connected to one of the first coupling members on the second side, and one of the second coupling members on the first side is connected to one of the second coupling members on the second side.
[0009] Furthermore, n is 2, the first coupling member includes 2 first protrusions, and the second coupling member includes 3 second protrusions.
[0010] Furthermore, each of the arc-shaped protrusions is centered on the apex of the box body near the arc-shaped protrusion.
[0011] Furthermore, the coupling component and the housing body are integrally formed.
[0012] Furthermore, it also includes a handle assembly, including a first handle mechanism, with the first handle mechanism disposed at the center of both the second side and the fourth side.
[0013] Furthermore, the handle assembly includes a second handle mechanism, which is provided at the joints on both different sides.
[0014] Furthermore, the four sides of the housing are provided with reinforcing structures, and the reinforcing structures are recessed grooves on each side.
[0015] The equipment cabinet of another embodiment of this application includes a stackable enclosure as described above, and also includes electrical components installed in the receiving cavity.

[0017] The aforementioned stackable box has at least the following beneficial effects: First and second coupling members are provided on both the first and third sides of the box body. The first protrusion of the first coupling member and the second protrusion of the second coupling member are both arc-shaped protrusions. These arc-shaped protrusions on the first and second coupling members serve a guiding function, allowing two stacked boxes to quickly align, facilitating stacking and ensuring good consistency on all four sides after stacking, thus improving stacking stability. Furthermore, the fact that both the first and second protrusions of the first and second coupling members are arc-shaped protrusions—that is, non-right-angle arc-shaped linear structures—effectively increases the horizontal resistance of the box during stacking, suppressing the shaking of the entire stacked box group during placement or transportation, effectively preventing the box from tipping over, thereby improving the stacking stability of the stackable box. The presence of first and second coupling members on both the first and third sides of the stackable box allows it to be stacked upright or upside down.

[0053] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0054] like Figure 1 , Figure 1a and Figure 1b As shown, one embodiment of this application discloses a stackable box 100, which includes a box body 110 and a coupling component.
[0055] The box body 110 has a receiving cavity and four sides circumferentially. These four sides are designated as first side 111, second side 112, third side 113, and fourth side 114, respectively. First side 111 and third side 113 face each other, and second side 112 and fourth side 114 face each other. Specifically, sealing plates 117 are provided at the front and rear of the box body 110. The two sealing plates 117 and the four sides define the receiving cavity of the box body 110.
[0056] The coupling assembly includes a first coupling structure and a second coupling structure. The first coupling structure includes a first coupling element 120, and the second coupling structure includes a second coupling element 130. A pair of first coupling elements 120 and a pair of second coupling elements 130 are respectively provided on a first side 111, and a pair of first coupling elements 120 and a pair of second coupling elements 130 are respectively provided on a third side 113. Specifically, the pair of first coupling elements 120 on the first side 111 is located on one diagonal of the first side 111 and is centrally symmetrical about the center of the first side 111. The pair of second coupling elements 130 on the first side 111 is located on the other diagonal of the first side 111 and is centrally symmetrical about the center of the first side 111. It should be understood that the center of the first side 111 is the intersection of the two diagonals of the first side 111. It should be understood that a pair of first coupling elements 120 refers to two first coupling elements 120; the diagonals are virtual diagonals, which can be determined based on the four vertices of each side. Specifically, a pair of first coupling elements 120 refers to two first coupling elements 120.
[0057] The first coupling member 120 includes n first protrusions 121, which surround n-1 first grooves 122. The second coupling member 130 includes n+1 arc-shaped second protrusions 131, which surround n second grooves 132. Here, n ≥ 1, and n is an integer. Both the first protrusions 121 and the second protrusions 131 are arc-shaped. It should be noted that each arc-shaped protrusion is centered on the vertex of the housing body 110 closest to it. Figure 4 As shown. That is, the center of the diagonal on each side is located outside the respective arcuate protrusions on that side.
[0058] Along the X direction, the projection of the first protrusion 121 is located in the second groove 132. In other words, along the X direction, the projection of the first protrusion 121 on the first side 111 can fall within the second groove 132 of the third side 113; the projection of the first protrusion 121 on the third side 113 can fall within the second groove 132 of the first side 111. That is, when two or more of the aforementioned stackable boxes 100 are stacked along the X direction (or vertically), the first coupling member 120 of the upper box can couple with the second coupling member 130 of the lower box; the first coupling member 120 of the lower box can couple with the second coupling member 130 of the upper box. Thus, vertical stacking of two or more boxes is achieved, such as... Figures 5 to 7 , Figure 10 As shown. It should be noted that the X direction is perpendicular to the first side surface 111 and the second side surface 112, as... Figure 1 As shown.
[0059] like Figure 1 and Figure 5 As shown, two adjacent first protrusions 121 of the first coupling member 120 form a first groove 122, and two adjacent second protrusions 131 of the second coupling member 130 define a second protrusion 131. The projection of the first protrusion 121 on the first side 111 can fall into the second groove 132 of the third side 113. That is, in the same stackable box 100, along the X direction, the first coupling member 120 on the first side 111 and the second coupling member 130 on the third side 113 are directly opposite each other. The two first coupling members 120 on the first side 111 are located on one diagonal of the first side 111, and the two second coupling members 130 on the first side 111 are located on the other diagonal of the first side 111. The first side 111 is rectangular. Therefore, when the first side 111 and the third side 113 of the stackable box 100 are reversed, that is, regardless of whether the first side 111 or the third side 113 is on top, the positions of the first coupling members 120 and the second coupling members 130 on the box body 110 are exactly the same before and after the reversal. Thus, it is not necessary to distinguish whether the first side 111 or the third side 113 of the box body 110 is on top during stacking, which facilitates the rapid stacking of the stackable box 100.
[0060] like Figures 1 to 3 , Figure 3aAs shown, in some embodiments, the second side 112 is provided with a pair of first coupling members 120 and a pair of second coupling members 130, and the fourth side 114 is provided with a pair of first coupling members 120 and a pair of second coupling members 130. The pair of first coupling members 120 on the second side 112 are located on one diagonal of the second side 112 and are centrally symmetrical about the center of the first side 111. The pair of second coupling members 130 on the second side 112 are located on the other diagonal of the second side 112 and are centrally symmetrical about the center of the second side 112. The center of the second side 112 is the intersection of the two diagonals of the second side 112. Along the Y direction, the projection of the first protrusion 121 on the second side 112 is located in the second groove 132 of the fourth side 114, and the projection of the first protrusion 121 on the fourth side 114 is located in the second groove 132 of the second side 112. The Y direction is a direction perpendicular to the second side 112 and the fourth side 114. Figure 1 As shown in the figure, one of the first coupling members 120 on the second side 112 is directly opposite to one of the second coupling members 130 on the fourth side 114. Both the second side 112 and the fourth side 114 are provided with first coupling members 120 and second coupling members 130, enabling the stackable boxes 100 to be stacked laterally (i.e., the Y direction is vertical). Figure 8 , Figure 9 and Figure 11 As shown.
[0061] Therefore, when the first side 111, the second side 112, the third side 113 and the fourth side 114 are all provided with the first coupling member 120 and the second coupling member 130 as described above, the stackable box 100 can be stacked horizontally or vertically, and can also be selected as a combination of horizontal and vertical stacking according to space requirements, which is conducive to optimizing the stacking space and selecting the appropriate stacking method according to the site space conditions.
[0062] Furthermore, such as Figure 2 and Figure 4As shown, the first coupling member 120 and the second coupling member 130 on the first side 111 are located at the four apex corners of the first side 111, and the first coupling member 120 and the second coupling member 130 on the second side 112 are located at the four apex corners of the second side 112. One of the first coupling members 120 on the first side 111 is connected to one of the first coupling members 120 on the second side 112, and one of the second coupling members 130 on the first side 111 is connected to one of the second coupling members 130 on the second side 112. In the figure, one of the first coupling members 120 on the first side 111 and one of the first coupling members 120 on the second side 112 are connected to each other. The two connected first coupling members 120 form a first coupling structure, which helps to improve the structural strength of the apex corner of the box body 110 and effectively prevents the box body 110 from breaking at the apex corner. Meanwhile, the first coupling structure is located at the top corner of the box body 110, serving as a foot for the stackable boxes 100 to be placed horizontally or vertically. This structure also provides strong stability when the stackable boxes 100 are placed, and elevates the box body 110 relative to the supporting plane, effectively preventing the box body 110 from being soaked by rainwater or rubbed by the supporting surface. It should be noted that two interconnected second coupling members 130 form a second coupling mechanism, and each of the eight top corners of the box body 110 forms either a first coupling mechanism or a second coupling mechanism, such as... Figure 2 As shown. In addition, when multiple stackable boxes 100 are stacked together, the stackable boxes 100 stacked on top of each other are subjected to resistance from the first coupling member 120 and the second coupling member 130 on the horizontal side, as well as resistance from the first coupling member 120 and the second coupling member 130 on the vertical side. This helps to improve the stacking stability of multiple stackable boxes 100, suppresses the shaking of the entire group of boxes during placement or transportation, and effectively prevents the boxes from tipping over.
[0063] In some embodiments, such as Figure 1a and Figure 1bAs shown, n is 2. The first coupling member 120 includes two first protrusions 121, and the second coupling member 130 includes three second protrusions 131. That is, the two first protrusions 121 of the first coupling member 120 define one first groove 122, and the three second protrusions 131 of the second coupling member 130 define two second grooves 132. When two stackable boxes 100 are stacked, the first coupling member 120 of one stackable box 100 is coupled to the second coupling member 130 of the other stackable box 100. That is, the first protrusion 121 and the second groove 132 are connected, and at least one second protrusion 131 is connected to the first groove 122, which helps to increase the friction between the coupling members. In other embodiments, the value of n can be selected as 3, 4, 5, etc., as needed.
[0064] In some embodiments, such as Figure 1a , Figure 1b and Figure 2 As shown, each arc-shaped protrusion is centered on the vertex of the box body 110 near the arc-shaped protrusion. In other words, the arc-shaped protrusions of the first coupling member 120 or the second coupling member 130 are arranged in multiple layers centered on the top corner of the box body 110 near its setting position.
[0065] In some embodiments, the coupling component and the housing body 110 are integrally formed. As one embodiment, the stackable housing 100 is made of plastic, and the coupling component and the housing body 110 are processed by injection molding, which helps to reduce costs.
[0066] In some embodiments, see Figure 1 As shown, the stackable box 100 also includes a handle assembly, including a first handle mechanism 141. The first handle mechanism 141 is provided in the middle of the second side 112 and the fourth side 114 to facilitate the handling or transportation of the stackable box 100.
[0067] In some embodiments, see Figure 1 As shown, the handle assembly includes a second handle mechanism 142, which is provided at the joint of two adjacent sides to facilitate the handling or transportation of the stackable box 100.
[0068] In some embodiments, the four sides of the housing are provided with reinforcing structures, each of which is a concave groove on each side to effectively improve the structural strength of the stackable housing 100. In this embodiment, the reinforcing structures include a first reinforcing structure 116 and a second reinforcing structure 118. Specifically, the second side 112 and the fourth side 114 are each provided with one or more of the second reinforcing structures 118. The first reinforcing structure 116 is an elongated groove extending along the X direction; the second reinforcing structure 118 is a rectangular groove, provided on the four sides of the housing body 110 to improve the structural strength of the four sides, such as... Figure 1 and Figure 2 As shown.
[0069] It should be noted that the aforementioned stackable enclosure 100 can serve as the enclosure for electronic and electrical equipment, with its internal cavities used for mounting electronic components. It should also be understood that the stackable enclosure 100 can be used in industries such as logistics and transportation.
[0070] See Figures 12 to 14 As shown, another embodiment of this application discloses an equipment cabinet 300, which includes the stackable housing 100 as described above, and also includes electrical components. The electrical components are installed within the receiving cavity of the stackable housing 100. By selecting the aforementioned stackable housing 100 as the shell of the equipment cabinet 300 and installing the electrical components of the equipment cabinet 300 within the receiving cavity of the stackable housing 100, the equipment cabinet 300 of this application possesses all the advantages of the stackable housing 100 as described above, such as stackability and effective suppression and prevention of shaking or tipping of the equipment cabinet 300, which will not be elaborated further here.
[0071] As one embodiment, such as Figures 12 to 14As shown, the equipment cabinet 300 is a power distribution box, and the aforementioned stackable enclosure 100 serves as the shell of this power distribution box. The electrical components of the power distribution box include multiple circuit breakers, multiple first connectors 330, and at least one second connector 340. The circuit breakers, first connectors 330, and second connectors 340 can be installed on the same sealing plate 117 of the stackable enclosure 100, or they can be installed on two different sealing plates 117 of the same stackable enclosure 100, depending on the actual situation. It should be understood that the stackable enclosure 100 has two sealing plates 117, one at the front and one at the back. The first connectors 330 and the second connectors 340 are used to connect to external cables. When there are multiple first connectors 330, the first connectors 330 can be selected to be of the same or different models according to actual usage requirements. Similarly, the second connectors 340 can also be selected to be of the same or different models according to usage requirements. It should be understood that when there are many electrical components in the distribution box, a fixed bracket can be provided inside the distribution box. The fixed bracket is installed in the receiving cavity and is fixedly connected to the inner wall of the stackable box 100. The electrical components are installed on the fixed bracket to ensure that the electrical components can be installed. In this embodiment, the first connector 330 is selected as an industrial socket, and the second connector 340 is an industrial plug. The distribution box in this embodiment is mainly used as a power distribution device in the film and television industry.
[0072] Furthermore, a waterproof cover is provided on the outside of the circuit breaker to improve its waterproof performance. Specifically, the circuit breaker includes multiple first circuit breakers and one second circuit breaker, and the cover plate 117 has openings corresponding to the positions of the first and second circuit breakers. A first waterproof cover 310 is provided on the opening corresponding to the first circuit breaker, and a second waterproof cover 320 is provided on the opening corresponding to the second circuit breaker, such as... Figure 12 As shown.
[0073] It is worth understanding that the electrical components of the equipment cabinet 300 can be other electrical or electronic components, thus enabling the equipment cabinet 300 to be applied to different industries and scenarios. For example, the equipment cabinet 300 can be a distribution box, dimmer cabinet, pass-through box, or other electrical equipment, without limitation.
[0074] See Figures 15 to 17As shown, another embodiment of this application discloses a transport trolley 200 for transporting the stackable box 100 described above. The transport trolley 200 includes a support plate 210 and a roller assembly 240. The support plate 210 is provided with a third coupling member 220 and a fourth coupling member 230. The third coupling member 220 is used to couple with a first coupling member 120, and the fourth coupling member 230 is used to couple with a second coupling member 130. The roller assembly 240 is mounted on the bottom of the support plate 210. In one embodiment, the layout of the third coupling member 220 and the fourth coupling member 230 corresponds to the positions of the first coupling member 120 and the second coupling member 130 on the first side 111, so that the stackable box 100 can be vertically placed on the small magnetic yoke 200 for transport. In this embodiment, the structure of the third coupling member 220 is the same as the structure of the second coupling member 130 to achieve a coupling connection with the first coupling member 120; the structure of the fourth coupling member 230 is the same as the structure of the first coupling member 120 to achieve a coupling link with the second coupling member 130.
[0075] The aforementioned transport cart 200, such as Figures 18 to 22 The container body 110 is equipped with a third coupling member 220 and a fourth coupling member 230, which can be coupled to the first coupling member 120 and the second coupling member 130 on the first side 111 or the third side 113 of the stackable container 100. This effectively prevents the stackable container 100 from slipping off the transport trolley 200 during transportation, improving handling safety. The first side 111 or the third side 113 of the container body 110 is provided with a limiting groove 115 that matches the roller assembly 240, restricting the roller assembly 240 from sliding on the container, thereby enabling multi-level stacking of the transport trolley 200 and the stackable container 100. Figure 20 As shown.
[0076] in, Figure 18 A schematic diagram showing the cooperation between the transport flatbed trolley 200 and the stackable container 100 is shown; Figure 19 A schematic diagram showing the cooperation between the transport trolley 200 and the equipment cabinet 300 is shown.
[0077] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
