Description

Technical Field

[0001] This application relates to the technical field of logistics equipment, and in particular to a box connection component, a box, and a method for assembling the box. Background Technology

[0002] With the continuous development of science and technology, increasingly sophisticated and complex products have emerged in our lives, such as computers, mobile phones and other smart devices, as well as home appliances. The more complex the product, the more parts it has, and the more processes it involves in the manufacturing process. Between different processes, a large number of semi-finished products or parts need to be transferred, and turnover boxes are a commonly used tool for this transfer.

[0003] Commercially available turnover boxes have their components and box body as a fixed whole. If any component or box body is damaged, the turnover box cannot be used for turnover work, and the connecting parts cannot be replaced. The turnover box as a whole can only be scrapped. Moreover, when the turnover box is not in use, the components cannot be effectively utilized because they are fixed to the box body. Summary of the Invention

[0004] This application provides a box connection component, a box, and a box assembly method to solve the problem in the prior art where the box is a fixedly connected whole, and if any component or the box is damaged, the turnover box cannot be used for turnover work, and the connecting component cannot be replaced.

[0005] In a first aspect, this application provides a housing connection assembly, including two connectors and a rotating body structure that rotatably connects the two connectors, each connector having a mounting groove formed thereon;

[0006] Each of the two connectors has a connecting hole at its adjacent ends. The rotating structure passes through the connecting holes of the two connectors in sequence to connect the two connectors together.

[0007] According to some embodiments of this application, the connector includes a first side plate, a second side plate, and a top plate. The first side plate and the second side plate are both connected to the lower surface of the top plate, and the first side plate and the second side plate are disposed opposite to each other. The mounting groove is formed between the first side plate, the second side plate, and the top plate.

[0008] According to some embodiments of this application, the first side plate includes a first side plate body and a snap-fit ​​structure elastically connected to the first side plate body, and the second side plate is provided with a clearance opening at the position corresponding to the snap-fit ​​structure to avoid the snap-fit ​​structure.

[0009] According to some embodiments of this application, the snap-fit ​​structure includes a first spring sheet elastically connected to the first side plate body, a pin disposed on the side of the first spring sheet facing the second side plate and fixedly connected at one end to the first spring sheet, and a snap-fit ​​block fixedly connected to the other end of the pin, wherein the snap-fit ​​block or the snap-fit ​​block and the pin pass through the clearance opening.

[0010] According to some embodiments of this application, the connector further includes a baffle connected to the outer edge of the top plate, and a limiting groove is formed between the baffle and the upper surface of the top plate.

[0011] According to some embodiments of this application, the rotating body structure includes a rotating body body and a first head and a second head located at both ends of the rotating body body, and the diameters of the first head and the second head are larger than the diameter of the connecting hole;

[0012] When the rotating body structure connects the two connecting members, the rotating body body passes through the connecting holes of the two connecting members, and the first head and the second head respectively limit the two connecting members.

[0013] Secondly, this application provides a housing that employs the housing connection assembly described above. The housing includes a bottom plate and a plurality of side walls rotatably connected to the bottom plate. Two adjacent side walls are connected by the housing connection assembly. The tops of two adjacent side walls are respectively inserted into the mounting slots of two connectors, and the top surfaces of the side walls are in contact with the top plates of the connectors.

[0014] According to some embodiments of this application, the connector includes a first side plate and a second side plate forming the mounting groove. The first side plate includes a first side plate body and a snap-fit ​​structure elastically connected to the first side plate body. The snap-fit ​​structure includes a first spring piece elastically connected to the first side plate body, a pin disposed on the side of the first spring piece facing the second side plate and fixedly connected at one end to the first spring piece, and a locking block fixedly connected to the other end of the pin. An avoidance hole is provided on the side wall at the position corresponding to the snap-fit ​​structure, and a second spring piece is elastically connected to the wall of the avoidance hole.

[0015] The snap-fit ​​structure has at least a first position and a second position. When the snap-fit ​​structure is in its first position, there is an angle between the first spring piece and the first side plate body, and the snap-fit ​​structure is relatively far away from the clearance hole and the mounting groove. When the snap-fit ​​structure is in its second position, the pin is located in the clearance hole, and the first spring piece and the snap-fit ​​block are respectively located on both sides of the clearance hole. During the process of the snap-fit ​​structure changing from the first position to the second position, the snap-fit ​​block pushes the second spring piece.

[0016] According to some embodiments of this application, the clearance hole is recessed downward to form a pin hole, and when the snap-fit ​​structure is in its second position, the pin is located in the pin hole.

[0017] According to some embodiments of this application, the housing further includes an edge banding strip, the edge banding strip having a downward-facing groove, and the portion of the top of the side wall that is offset from the position of the connector extending into the groove to be covered by the edge banding strip.

[0018] Thirdly, this application provides a method for assembling a box, applicable to the box as described above, the method comprising the following steps:

[0019] The connectors are respectively installed onto two adjacent side walls of the housing;

[0020] The two connecting parts are connected by the rotating body structure;

[0021] The edge banding strip of the box body is installed onto the side wall.

[0022] According to some embodiments of this application, the step of installing the connectors onto two adjacent side walls of the housing includes the following steps:

[0023] Adjust the snap-fit ​​structure of the connector to a first position, so that there is an angle between the first spring piece of the snap-fit ​​structure and the first side plate where the snap-fit ​​structure is located, so that the snap-fit ​​structure is away from the mounting groove;

[0024] The connector is installed to the top of the side wall through the mounting slot;

[0025] Adjust the snap-fit ​​structure from its first position to its second position, so that the snap-fit ​​block of the snap-fit ​​structure pushes against the second spring piece of the side wall, and the pin of the snap-fit ​​structure extends into the clearance hole of the side wall;

[0026] The adjustment to the snap-fit ​​structure is undone, the pin falls into the pin hole of the side wall, and the top surface of the side wall contacts the top plate of the connector.

[0027] The technical solutions provided in this application have the following advantages compared with the prior art:

[0028] This application provides a box connection assembly, a box, and a box assembly method. The box connection assembly includes two connectors and a rotating structure that rotatably connects the two connectors. Each connector has a mounting groove. Adjacent ends of the two connectors are provided with connecting holes. The rotating structure passes through the connecting holes of the two connectors sequentially to connect them. The mounting groove allows connection to a side plate of the box, and the rotating structure enables the two connectors to rotate, achieving the purpose of box assembly and disassembly. This allows for disassembly and replacement when any component or part of the box is damaged. This application effectively solves the problem in the prior art where the box is a fixed, integrated unit, and damage to any component or part prevents the turnover box from being used or the connecting parts from being replaced.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0049] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0050] Firstly, such as Figures 1 to 9 As shown, this application provides a box connection assembly, including two connectors 10 and a rotating structure 20 that rotatably connects the two connectors 10. Each connector 10 has a mounting groove 11. Adjacent ends of the two connectors 10 are provided with connecting holes 12. The rotating structure 20 passes through the connecting holes 12 of the two connectors 10 sequentially to connect them. Through the mounting grooves 11, the connectors 10 can be connected to a side wall 40 of the box. The rotating structure 20 allows the two connectors 10 to be rotatably connected, achieving the purpose of disassembling and assembling the box. This allows for disassembly and replacement when any component or part of the box is damaged. This application effectively solves the problem in the prior art where the box is a fixed, integrated unit, and damage to any component or part prevents the turnover box from being used or the connecting parts from being replaced.

[0051] It should be noted that the two connectors 10 are rotatably designed to adapt to side walls 40 with different angular relationships, such as 45°, 60°, or 90°, or any other arbitrary angular relationship. This enhances adaptability, allowing for the replacement of connectors between different turnover boxes. Furthermore, after disassembling the rotating structure 20, the connectors 10 can be interchanged, improving interchangeability. The connectors 10 can also be removed and placed independently without affecting the box's placement. The detachable connection of multiple connectors 10 between adjacent side walls 40 strengthens the overall structural strength of the box after the adjacent side walls 40 are connected. The engagement between the mounting groove 11 and the side wall 40 can be clamped or directly locked, preventing the connectors 10 from easily detaching from the side wall 40.

[0052] like Figures 1 to 8 As shown, in this embodiment, the connector 10 includes a first side plate 13, a second side plate 14, and a top plate 15. Both the first side plate 13 and the second side plate 14 are connected to the lower surface of the top plate 15, and are arranged opposite to each other. A mounting groove 11 is formed between the first side plate 13, the second side plate 14, and the top plate 15. The arrangement of the first side plate 13 and the second side plate 14 results in a compact structure that is easy to manufacture. Specifically, it can be formed by welding, bending, or integral molding, which helps control the precision of the mounting groove 11. The processing of the sheet metal is controllable, and the integrated structure has high strength, suitable for the load-bearing requirements of the turnover box, reducing the possibility of damage. It should be noted that the mounting groove 11 clamps the upper edge of the side wall 40 along its opening direction. The connector 10, through its own weight, brings the lower surface of the top plate 15 into contact with the upper edge of the side wall 40, resulting in a better fit between the connector 10 and the side wall 40, making it less prone to detachment.

[0053] Furthermore, the two opposing surfaces on the first side plate 13 and the second side plate 14 are arranged in parallel, and the two surfaces and the top plate 15 form a mounting groove 11. The mounting groove 11 is clearance-fitted with the corresponding side wall 40, and the side wall 40 can restrict part of the freedom of the connector 10, that is, the connector 10 can only slide along the side extension direction of the side wall 40.

[0054] like Figures 1 to 8As shown, in this embodiment, the first side plate 13 includes a first side plate body 131 and a snap-fit ​​structure 16 elastically connected to the first side plate body 131. The second side plate 14 has a clearance opening 141 at the position corresponding to the snap-fit ​​structure 16 to avoid the snap-fit ​​structure 16. The snap-fit ​​structure 16 can fix the side wall 40, increasing the connection strength between them. The elastic connection allows the snap-fit ​​structure 16 to move relatively closer to or further away from the second side plate 14 to adjust the distance between them, thereby locking and unlocking the side wall 40. During locking, the snap-fit ​​structure 16 can push against and snap onto the side wall 40, making the side wall 40 more tightly connected to the connector 10 and reducing the possibility of detachment. The elastic connection allows the snap-fit ​​structure 16 to spring back without external interference. After the connector 10 is removed, the snap-fit ​​structure 16 can reset, facilitating subsequent use and improving assembly performance.

[0055] Furthermore, such as Figures 1 to 8 As shown, in this embodiment, the snap-fit ​​structure 16 includes a first spring piece 161 elastically connected to the first side plate body 131, a pin 162 disposed on the side of the first spring piece 161 facing the second side plate 14 and fixedly connected at one end to the first spring piece 161, and a locking block 163 fixedly connected to the other end of the pin 162. When the snap-fit ​​structure 16 is in its second position (the second position of the snap-fit ​​structure 16 will be described in detail below), the locking block 163 or the locking block 163 and the pin 162 pass through the clearance opening 141. The first spring piece 161 enables the snap-fit ​​structure 16 to be elastically connected to the first side plate body 131. The pin 162 is used to connect the first spring piece 161 and the locking block 163, so that the locking block 163 can be supported. During assembly, the clearance opening 141 allows the locking block 163 or the locking block 163 and the pin 162 to pass through.

[0056] It should be noted that a through-hole fitting pin 162 can be provided on the side wall 40. The end of the locking block 163 away from the pin 162 can be detachably connected to the end of the pin 162 away from the first spring piece 161. This arrangement allows the locking block 163 to be disassembled, allowing the pin 162 to pass through the through hole, and then the locking block 163 and the pin 162 to be connected, thereby clamping the side wall 40. Specifically, the connection method between the locking block 163 and the pin 162 can be a threaded connection or a snap-fit ​​connection.

[0057] like Figures 1 to 8 As shown, in the technical solution of this embodiment, the connector 10 also has a baffle 17, which is connected to the outer edge of the top plate 15, and a limiting groove 18 is formed between the baffle 17 and the upper surface of the top plate 15.

[0058] The baffle 17 of a single connector 10 forms a limiting groove 18. Multiple limiting grooves 18 of connectors 10 can be combined to form a limiting space. Since the baffle 17 is connected to the outer edge of the top plate 15, the limiting space is larger than the bottom area of ​​the box. When the boxes are stacked, the bottom of the box can be fitted with each baffle 17 with a clearance, allowing for the simultaneous transport of multiple boxes and the transfer of a large amount of material. The upper surface of the top plate 15 is mainly used to adapt to the bottom of the box; specifically, it can be provided with striped friction textures or grooves for anti-slip structure. It should be noted that the baffle 17 and the top plate 15 are connected as one piece by welding or integral molding.

[0059] It should be noted that the baffle 17 can be configured such that its upper end is inclined towards the center line of the box. This configuration allows the baffle 17 to clamp or push against the side wall 40 when the boxes are stacked, thereby making the connection between the upper and lower boxes more compact and reliable.

[0060] like Figure 1 and Figure 9 As shown, in this embodiment, the rotating body structure 20 includes a rotating body body 21 and a first head 22 and a second head 23 located at both ends of the rotating body body 21, respectively. The diameters of the first head 22 and the second head 23 are larger than the diameter of the connecting hole 12. When the rotating body structure 20 connects the two connectors 10, the rotating body body 21 passes through the connecting hole 12 of the two connectors 10, and the first head 22 and the second head 23 respectively limit the two connectors 10. The first head 22 and the second head 23 are provided to limit the two connectors 10, preventing them from falling off after rotational connection and ensuring the connection effect.

[0061] In the technical solution of this embodiment, the first head 22 and / or the second head 23 are threaded connectors. The rotating body 21 can be a threaded rod or a smooth rod with threads at both ends. The connecting hole 12 can be a through hole, a countersunk hole, or a threaded hole. In a specific embodiment, the rotating body 21 is a threaded rod, and the first head 22 and the second head 23 are nuts connected to the two ends of the threaded rod by threads. The connecting hole 12 is a through hole or a countersunk hole, wherein the through hole portion is clearance-fitted with the threaded rod, and the first head 22 and the second head 23 are limited at both ends of the through hole portion; or, the rotating body 21 is a smooth rod, and the two ends of the smooth rod are provided with threaded sections. The first head 22 and the second head 23 are nuts connected to the threaded sections by threads; or, the first head 22 and the rotating body 21 are an integral screw, the second head 23 is a nut, and the connecting hole 12 is a countersunk hole. After assembly, the first head 22 is located in the countersunk hole, and after the second head 23 is threadedly connected to the rotating body 21, it is located in the countersunk hole to form a limit.

[0062] In one alternative embodiment, the rotating body structure 20 is a bolt, and at least one connecting hole 12 is provided with internal threads, with the rotating body structure 20 threadedly connected to the connecting hole 12. The internal thread of at least one connecting hole 12 enables threaded connection with the bolt, allowing one of the two connecting parts 10 to rotate relative to the other connecting part 10 and the rotating body structure 20, thus adjusting the angle. This configuration provides the rotating body structure 20 with a fixed connection, avoiding the risk of it falling or slipping out, and enhancing its practicality.

[0063] Furthermore, a nut can be provided at the bottom of the bolt, and the nut and the nut end of the bolt form multiple connecting holes 12 for limiting, so that the two connectors 10 will not fall off after they are connected.

[0064] It should be noted that, in an alternative embodiment, the rotating body structure 20 can also be a pin. The pin can also enable the connector 10 to rotate and is more convenient to operate. It can be inserted into the connecting hole 12 by gravity. The pin can be set such that the diameter of the end that enters the connecting hole 12 is smaller than the end that is close to the first head 22, and the position of the first head 22 is larger than the diameter of the connecting hole 12. This will cause the connecting hole 12 and the pin to lock under the action of gravity, thereby preventing the pin from falling off.

[0065] The number of connecting holes 12 in the connector 10 is not limited. The connecting holes 12 of adjacent connectors 10 are compatible. Provided that the upper surfaces of the top plates 15 of the two connectors 10 are on the same plane, the positions of the connecting holes 12 are staggered, and the axes of the connecting holes 12 coincide. For example... Figure 1 As shown, in the technical solution of this embodiment, the number of connecting holes 12 of two adjacent connectors 10 is one and two respectively. These three connecting holes 12 are stacked along their axial direction. This arrangement results in a compact structure and tight connection. Since the connector 10 is fixed from the position of the connecting hole 12 after installation, the force on its end away from the connecting hole 12 will be uneven. If the axes of the three connecting holes 12 do not coincide at this time, the connector 10 will move when the box is transported. In severe cases, vibration will occur, which will lead to detachment and reduce the structural strength of the box assembly.

[0066] Secondly, such as Figure 10 and Figure 11 As shown, this application provides a box body using the box body connecting assembly in the above embodiment. The box body includes a bottom plate 30 and a plurality of side walls 40 rotatably connected to the bottom plate 30. Two adjacent side walls 40 are connected by the box body connecting assembly. The tops of two adjacent side walls 40 are respectively inserted into the mounting slots 11 of two connectors 10, and the top surface of the side wall 40 is in contact with the top plate 15 of the connector 10.

[0067] like Figures 1 to 11 As shown, the connector 10 includes a first side plate 13 and a second side plate 14. The first side plate 13 includes a first side plate body 131 and a snap-fit ​​structure 16 that is elastically connected to the first side plate body 131. The snap-fit ​​structure 16 includes a first spring piece 161 that is elastically connected to the first side plate body 131, a pin 162 that is disposed on the side of the first spring piece 161 facing the second side plate 14 and fixedly connected to the first spring piece 161 at one end, and a snap-fit ​​block 163 that is fixedly connected to the other end of the pin 162. A clearance hole 41 is provided at the position of the snap-fit ​​structure 16 on the side wall 40, and a second spring piece 42 is elastically connected to the hole wall of the clearance hole 41.

[0068] The snap-fit ​​structure 16 has at least a first position and a second position. The first position of the snap-fit ​​structure 16 is the position where there is an angle between the first spring piece 161 and the first side plate body 131. In the first position, the snap-fit ​​structure 16 is relatively far away from the clearance hole 41 and the mounting groove 11. The second position of the snap-fit ​​structure 16 is the position where the first spring piece 161 is not subjected to external force, that is, the position where there is no angle between the first spring piece 161 and the first side plate body 131. During the assembly of connector 10, snap-fit ​​structure 16 is first adjusted from its second position to its first position to make room for the mounting groove 11 and side wall 40 to fit together; then it is switched from the first position to the second position, the first spring piece 161 rotates in the direction close to the second side plate 14, and the snap-fit ​​block 163 of snap-fit ​​structure 16 pushes against the second spring piece 42. When snap-fit ​​structure 16 is back to its second position, pin 162 is located in clearance hole 41, and the first spring piece 161 and snap-fit ​​block 163 are located on both sides of clearance hole 41 respectively; during the process of snap-fit ​​structure 16 changing from the first position to the second position, snap-fit ​​block 163 pushes against the second spring piece 42.

[0069] It should be noted that there are multiple snap-fit ​​structures 16, and multiple corresponding clearance openings 141, which are set along the extension direction of the mounting groove 11. Multiple clearance holes 41 and second spring pieces 42 are provided on the corresponding side wall 40, so that multiple limiting points are formed between the side wall 40 and the connector 10.

[0070] The first spring 161 of the snap-fit ​​structure 16 can be made of elastic steel, which has a larger elastic deformation range and a longer service life. The first spring 161 can also be made of non-metallic materials such as plastic or rubber. Such a first spring 161 has sufficient strength to meet the usage requirements and can reduce the overall weight of the connector 10, thereby reducing the overall weight after assembly and facilitating handling.

[0071] like Figure 12As shown, in the technical solution of this embodiment, the clearance hole 41 is recessed downward to form a pin hole 43. When the snap-fit ​​structure 16 is in its second position, the pin 162 is located in the pin hole 43. The pin hole 43 restricts the pin 162's degree of freedom in its circumferential direction, and the second spring 42 restricts the pin 162 from disengaging from the pin hole 43.

[0072] Furthermore, in the technical solution of the above embodiment, a locking block 163 is provided at one end of the snap-fit ​​structure 16 near the avoidance opening 141. The size of the locking block 163 is larger than the size of the pin 162. After the connector 10 is assembled, the locking block 163 and the first spring piece 161 are located on both sides of the side wall 40, respectively, to clamp the side wall 40, prevent the connector 10 from shaking relative to the side wall 40, improve the connection stability and the service life of the connector 10 and the housing.

[0073] like Figure 3 , Figure 4 , Figure 6 and Figure 5 As shown, in the technical solution of this embodiment, the locking block 163 is provided with two shapes: a square locking block 163 and a frustum-shaped locking block 163. The two types of locking blocks 163 have the same effect, but can further distinguish the connector 10. For example, the connector 10 with the square locking block 163 is used for the installation of the side plate side wall 40 with a longer length, and the connector 10 with the frustum-shaped locking block 163 is used for the installation of the side wall 40 with a shorter length, making the disassembly and classification during recycling clearer.

[0074] Furthermore, the locking block 163 can be configured with an internally threaded hole, and the pin 162 has an external thread on the outer periphery of the end near the locking block 163. The two can be connected by threads to adjust the fit between the locking block 163 and the first spring piece 161, making the connection between the two tighter. It should be noted that when using the threaded connection, the pin 162 can pass directly through the pin hole 43, and the assembly process of the connector 10 does not require pushing against the second spring piece 42. The second spring piece 42 can be used to adjust the gap between the side wall 40 and the first side plate 13 and the second side plate 14, so as to make the connection between the two tighter.

[0075] like Figure 10 , Figure 11 and Figure 13As shown, in this embodiment, the box also includes an edge banding strip 50. The edge banding strip 50 has a downward-facing groove 51. The portion of the top of the side wall 40, offset from the position of the connector 10, extends into the groove 51 and is covered by the edge banding strip 50. Specifically, the edge banding strip 50 is engaged at the position of the side wall 40 where the connector 10 is not located. The edge banding strip 50 serves two purposes: firstly, it protects the upper edge of the side wall 40 when the boxes are stacked; secondly, it effectively increases the width of the upper edge of the side wall 40, making the stacking more stable. At least one protrusion 52 is provided on the groove wall of the groove 51. The protrusion 52 is used to clamp the side wall 40, ensuring that the edge banding strip 50 does not detach from the side wall 40. It should be noted that the length of the edge banding strip 50 can be adjusted or combined according to actual needs to adapt to different boxes.

[0076] like Figure 10 and Figure 11 As shown, in the technical solution of this embodiment, the side wall 40 of the box can be provided with holes for handling, allowing the palm to be inserted to facilitate the handling of the entire box assembly.

[0077] At both ends of the upper edge of the side wall 40, there are clearance positions. After assembly, the connection holes 12 of two adjacent connectors 10 and the rotating structure 20 for connecting the two adjacent connectors 10 are located in the clearance positions.

[0078] The box provided in this application embodiment is detachable, foldable, stackable, and reusable, mainly used for the turnover of small parts, such as electronic motherboards and small boards. Compared with the riveted fixing structure used in traditional turnover boxes, it solves the problems of existing turnover boxes that cannot be folded, parts that cannot be disassembled, and parts that cannot be reused. If any part of the box is damaged, it can be replaced individually. After the parts are disassembled, the box can be folded for storage, taking up little space. The connector 10 and the edge strip 50 can adapt to box components of different sizes.

[0079] Thirdly, this application provides a method for assembling a box, applicable to the box as described in the above embodiments. The method for assembling the box includes the following steps:

[0080] Install the connectors 10 onto the two adjacent side walls 40 of the housing respectively;

[0081] The two connectors 10 are connected by the rotating body structure 20;

[0082] Install the edge banding strip 50 of the box onto the side wall 40.

[0083] In the technical solution of this embodiment, the connector 10 is installed onto two adjacent side walls 40 of the housing, including the following steps:

[0084] Adjust the snap-fit ​​structure 16 of the connector 10 to the first position, so that the first spring piece 161 of the snap-fit ​​structure 16 and the first side plate 13 where the snap-fit ​​structure 16 is located have an angle, so that the snap-fit ​​structure 16 is away from the mounting groove 11, making room for the mounting groove 11 to cooperate with the side wall 40.

[0085] The connector 10 is installed to the top of the side wall 40 via the mounting slot 11.

[0086] When the snap-fit ​​structure 16 is adjusted from the first position to the second position, the snap-fit ​​block 163 of the snap-fit ​​structure 16 pushes the second spring piece 42 of the side wall 40, and the pin 162 of the snap-fit ​​structure 16 extends into the clearance hole 41 of the side wall 40; during the process of adjusting the snap-fit ​​structure 16 from the first position to the second position, the second spring piece 42 rotates in a direction away from the first side plate 13.

[0087] The adjustment to the snap-fit ​​structure 16 is cancelled. Under the action of the weight of the connector 10 itself, the pin 162 falls into the pin hole 43 of the side wall 40, and the top surface of the side wall 40 contacts the top plate 15 of the connector 10.

[0088] It should be noted that when the pin 162 falls into the pin hole 43 of the side wall 40, the first spring piece 161 can deflect at a certain angle in the direction close to the second side plate 14. On the one hand, this can counteract the deformation caused by the torsion from the second position to the first position and eliminate the stress of the deformation. On the other hand, this can make the locking block 163 move away from the second spring piece 42, so that the second spring piece 42 can be reset more smoothly to refill the clearance hole 41, and also form a limit on the locking block 163.
