Description

Technical Field

[0001] This application relates to the technical field of enclosure installation, and in particular to an enclosure protection connection mechanism. Background Technology

[0002] In traditional container handling, multiple containers are typically stacked simply on top of each other. This is not only inefficient but also poses a risk of containers tipping over. A well-designed container connection method can improve space utilization and enhance the stability of the overall structure, which is crucial for ensuring the safe transport and effective storage of goods. A good connection mechanism can also reduce costs and improve operational efficiency. By incorporating connecting structures between adjacent containers to facilitate handling, both convenience and stability can be improved.

[0003] To facilitate handling, connecting structures are typically installed between adjacent boxes to improve their ease of transport and stability. Currently, snap-fit ​​or hinged connections are the primary methods used. However, snap-fit ​​or hinged connections generally suffer from structural complexity and poor positioning accuracy. When two boxes are connected, misalignment often occurs due to this inaccuracy, requiring repeated adjustments and resulting in low connection efficiency. Furthermore, prolonged use of these connections can lead to loosening during transport due to shaking and bumps, compromising the tight seal between boxes and potentially damaging the goods.

[0004] In view of the above-mentioned technologies, it is necessary to propose a connection mechanism for enclosure protection to solve one of the above-mentioned technical problems. Summary of the Invention

[0005] To address one of the aforementioned technical problems, this application provides a connection mechanism for enclosure protection.

[0006] This application provides a protective connection mechanism for a housing, employing the following technical solution:

[0007] A protective connection mechanism for a housing includes:

[0008] The bottom connecting assembly includes a bottom frame symmetrically arranged at the bottom of the box and a reinforcing frame arranged within the bottom frame. The bottom frame and the reinforcing frame are detachably connected to the bottom of the box, and both the bottom frame and the reinforcing frame have a mating interface in the middle.

[0009] An assembly block, wherein the assembly block is disposed corresponding to the mating interface, the assembly block has a through slot, and one end of the assembly block with the slot is inserted into the mating interface, while the other end of the assembly block abuts against the end face of the reinforcing frame corresponding to the mating interface; and

[0010] The top connecting assembly includes a top frame symmetrically arranged on the top of the housing. The top of the top frame has a plurality of stepped structures arranged sequentially. The top frame has a locking groove corresponding to the stepped structures. An insert block is movably arranged in the locking groove. The insert block is inserted into the slot at the assembly block to realize the combination of the top frame and the bottom frame.

[0011] In this process, several boxes are vertically assembled by combining the bottom connecting component and the top connecting component.

[0012] By adopting the above technical solution, the bottom frame and reinforcing frame in the bottom connecting assembly are detachably connected to the bottom of the box, which can enhance the structural strength of the bottom of the box. The bottom frame and reinforcing frame have a mating interface in the middle to facilitate the mating with the assembly block. The assembly block has a slot at one end that is inserted into the mating interface, and the other end abuts against the end face of the reinforcing frame, which can make the assembly block firmly installed at the bottom of the box. The top frame has a locking groove corresponding to the step structure with a movable insert block that is inserted into the slot of the assembly block, thereby realizing the combination of the top frame and the bottom frame. This combination method can splice and combine several boxes in the vertical direction, which not only facilitates the assembly of the boxes, but also makes multiple boxes form a stable overall structure after splicing, effectively improving the stability and safety of the boxes when stacked, and enhancing the protection of the items inside the boxes.

[0013] Optionally, a connecting flange is provided at the bottom edge of the bottom frame, and the connecting flange is provided with a movable notch for the movement of the insert block. The step structure includes a first step and a second step arranged sequentially on the top of the top frame. When the bottom frame is connected to the top frame, the first step abuts against the bottom of the connecting flange, and the second step engages with the inner surface of the connecting flange.

[0014] By adopting the above technical solution, the movable notch at the connecting flange on the bottom edge of the bottom frame allows the insert block to move within the movable notch, ensuring that the insert block is smoothly inserted into the slot of the assembly block to achieve the combination of the top frame and the bottom frame; the top of the top frame in the top connecting assembly is provided with a first step and a second step, and the insert block is movable within the locking groove on the second step, inserting into the slot of the assembly block, thereby achieving the combination of the top frame and the bottom frame; when the bottom frame and the top frame are connected, the first step of the top frame abuts against the bottom of the connecting flange, which can provide support for the top frame from below and prevent the top frame from excessive displacement in the horizontal direction; at the same time, the second step of the top frame engages with the inner surface of the connecting flange, further enhancing the tightness and stability of the connection between the top frame and the bottom frame, making the connection between each box more stable and reliable when several boxes are vertically spliced ​​together, and improving the overall strength and stability of the entire box splicing structure.

[0015] Optionally, the upper two sides of the bottom frame are provided with first corner frames for supporting the bottom corners of the box, and the lower two sides of the top frame are provided with second corner frames for supporting the top corners of the box, for stabilizing the splicing and combination of several boxes.

[0016] By adopting the above technical solution, the first corner frames set on both sides of the upper end of the bottom frame can support the bottom corners of the box, and the second corner frames set on both sides of the lower end of the top frame can support the top corners of the box. This support structure can disperse the external force on the box during splicing and assembly, reduce stress concentration at the corners, and thus ensure that the position of each box is relatively fixed when several boxes are spliced ​​and assembled, avoiding shaking or displacement caused by external forces, and improving the stability of splicing and assembling several boxes.

[0017] Optionally, the insertion block has a locking block near the extension of the slot, and after the insertion block is inserted into the slot, the bottom protrusion of the locking block engages with the assembly block.

[0018] By adopting the above technical solution, after the insert block is inserted into the slot, the protruding part at the bottom of its extended locking block can form a locking engagement with the assembly block. This locking structure can effectively restrict the insert block from coming out of the slot, enhance the stability of the connection between the insert block and the assembly block, and thus improve the stability of the combination of the top frame and the bottom frame, ensuring that the connection of several boxes is more reliable when they are assembled in the vertical direction.

[0019] Optionally, a pin hole is provided in the locking groove, and a limiting hole is provided in the insert block. When the pin hole coincides with the limiting hole, the insert block is limited in the locking groove by inserting a pin rod into the pin hole and the limiting hole.

[0020] By adopting the above technical solution, the insert block is stably kept in its current position, preventing it from sliding or coming out at will, thereby ensuring the stability of the connection between the top frame and the bottom frame, and thus ensuring the reliability of the vertical splicing and combination structure of several boxes.

[0021] Optionally, a bearing block is provided in the locking groove above the insert block, a swing groove is provided at the bottom of the bearing block, a swing rod is rotatably provided in the swing groove, a limit block is provided at the bottom of the swing rod, and the limit block is provided in the limit hole for limiting the insertion block.

[0022] By adopting the above technical solution, the limiting block at the bottom of the swing rod rotating in the swing groove can be placed in the limiting hole of the insert block. After the insert block is inserted into the slot of the assembly block to complete the combination of the top frame and the bottom frame, the swing rod can rotate in the swing groove to make the limiting block enter the limiting hole, thereby limiting the insert block from above and preventing the insert block from coming out of the slot. This effectively improves the stability of the combination of the top frame and the bottom frame, and thus ensures the stability of the vertical splicing combination structure of multiple boxes.

[0023] Optionally, the axial end face of the bearing block is rotatably provided with a baffle corresponding to the opening of the swing groove, which is used to block the swing rod when the insert block is limited, so as to prevent the swing rod from swinging in the axial direction of the insert block, and so that the limiting block limits the insert block in the limiting hole.

[0024] By adopting the above technical solution, when limiting the insertion block, the baffle plate that is rotated on the axial end face of the bearing block corresponding to the opening of the swing groove will block the swing rod; when the swing rod rotates in the swing groove and the limiting block is placed in the limiting hole of the insertion block, the baffle plate can prevent the swing rod from swinging in the direction of the insertion block moving out axially, thereby ensuring that the limiting block can be continuously and stably placed in the limiting hole, thus achieving effective limiting of the insertion block, ensuring that the insertion block is fixed in the locking groove, and improving the stability and reliability of the entire connection mechanism.

[0025] Optionally, elastic elements are provided on both sides of the limiting block, and the elastic elements are in contact with the inner wall of the limiting hole to increase the connection stability between the insert block and the limiting block.

[0026] By adopting the above technical solution, when the insert block is inserted into the slot and the limiting block is placed in the limiting hole, the elastic element will undergo elastic deformation to generate elastic force acting on the inner wall of the limiting hole. This elastic force can fill the gap that may exist between the limiting block and the limiting hole, reduce the relative shaking and displacement between the two, thereby effectively increasing the connection stability between the insert block and the limiting block, and thus ensuring the structural stability of the entire housing protection connection mechanism.

[0027] Optionally, it also includes an overlapping assembly for the lateral combination of several boxes. The overlapping assembly includes several overlapping pieces for the lateral splicing of adjacent boxes and disposed outside the second corner frame. The end face of the overlapping piece is provided with a frame. One of the frames is provided with a connecting rod. A threaded cylinder is rotatably and slidably provided on the connecting rod. Another frame is provided with a threaded rod. The inner wall of the threaded cylinder is threadedly connected to the outer surface of the threaded rod.

[0028] By adopting the above technical solution, the set overlapping components can realize the lateral combination of several boxes. Specifically, the overlapping pieces set outside the second corner frame are used for the lateral splicing of adjacent boxes. The frames on the end face of the overlapping pieces are respectively set with connecting rods and threaded rods. When the boxes are spliced ​​laterally, the threaded rod on another frame follows the box that moves laterally and splices with the initial box. After they are placed side by side, the threaded rod and the connecting rod on one of the frames of the initial box are at the same horizontal position, and are threadedly combined with the threaded rod by sliding and rotating the threaded cylinder. Due to the threaded engagement, adjacent boxes can move closer or further away from each other, thereby completing the lateral splicing combination, effectively improving the convenience and stability of the lateral connection of multiple boxes.

[0029] Optionally, the head of the connecting rod is provided with a fixing plate, which is disposed inside the threaded cylinder and is used to limit the sliding movement of the threaded cylinder.

[0030] By adopting the above technical solution, when the threaded cylinder rotates and slides on the connecting rod, the fixing plate will restrict the threaded cylinder from continuing to slide towards the head of the connecting rod, preventing the threaded cylinder from coming off the connecting rod, thereby achieving effective limiting of the threaded cylinder's sliding, ensuring that the overlapping components can work stably during the lateral assembly of several boxes, and making the lateral splicing of adjacent boxes more reliable.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By combining the bottom and top connecting components, several boxes can be precisely and efficiently assembled vertically, effectively overcoming the difficulties of existing technologies in accurately assembling multiple boxes vertically, and fully meeting the actual needs of large-scale, high-efficiency box assembly; the connecting flange of the bottom frame fits tightly with the first and second steps of the top frame, while the inserts are accurately inserted into the slots of the assembly blocks, comprehensively enhancing the stability of the connection between the top and bottom frames, fundamentally avoiding the problem of loosening due to wear of the connecting parts as in existing technologies; the locking blocks of the inserts engage with the assembly blocks, further strengthening the connection between the inserts and the assembly blocks, preventing the inserts from accidentally coming out, and enhancing the reliability of the connection between the top and bottom frames;

[0033] 2. The load-bearing block, swing rod, limit block, and baffle work together to provide multiple limits for the insertion block, further improving the reliability of the insertion block's limit.

[0034] 3. The overlapping assembly, through the cooperation of overlapping pieces, frames, connecting rods, threaded cylinders and threaded rods, enables the horizontal combination of several boxes, expanding the ways of box combination and improving space utilization efficiency.

[0047] The following is in conjunction with the accompanying drawings. Figures 1-11 This application will be described in further detail.

[0048] Example 1, Reference Figures 1-4 This application discloses a box protection connection mechanism, including: a bottom connection component 1, an assembly block 2 and a top connection component 3.

[0049] The bottom connecting component 1 includes a bottom frame 11 symmetrically arranged at the bottom of the housing 7 and a reinforcing frame 12 arranged within the bottom frame 11. The bottom frame 11 and the reinforcing frame 12 are detachably connected to the bottom of the housing 7. Both the bottom frame 11 and the reinforcing frame 12 have a mating interface 13 in the middle. The assembly block 2 is arranged corresponding to the mating interface 13. The assembly block 2 has a through slot 21, and one end of the assembly block 2 with the slot 21 is inserted into the mating interface 13, while the other end of the assembly block 2 abuts against the end face of the reinforcing frame 12. The top connecting component 3 includes a top frame 31 symmetrically arranged at the top of the housing 7. The top of the top frame 31 has multiple stepped structures arranged sequentially. The top frame 31 has a locking groove 34 corresponding to the stepped structures. An insert block 35 is movably arranged in the locking groove 34 and is inserted into the slot 21 at the assembly block 2 to realize the combination of the top frame 31 and the bottom frame 11. The bottom connecting component 1 and the top connecting component 3 are combined vertically to assemble several housings 7.

[0050] The bottom frame 11 and reinforcing frame 12 in the bottom connecting assembly 1 are detachably connected to the bottom of the box 7, which can enhance the structural strength of the bottom of the box 7. The bottom frame 11 and reinforcing frame 12 have a mating interface 13 in the middle to facilitate the cooperation with the assembly block 2. One end of the assembly block 2 with a slot 21 is inserted into the mating interface 13, and the other end abuts against the end face of the reinforcing frame 12, so that the assembly block 2 can be stably installed at the bottom of the box 7. The top frame 31 is movably set with an insert 35 in the locking groove 34 corresponding to the stepped structure. The insert 35 is inserted into the slot 21 of the assembly block 2, thereby realizing the combination of the top frame 31 and the bottom frame 11. This combination method can splice and combine several boxes 7 in the vertical direction, which not only facilitates the assembly of the box 7, but also makes multiple boxes 7 form a stable overall structure after splicing, effectively improving the stability and safety of the box 7 when stacked, and enhancing the protection of the items inside the box 7.

[0051] refer to Figure 1 and Figure 2In this embodiment, more specifically, a connecting flange 14 is provided at the bottom edge of the bottom frame 11. The connecting flange 14 is provided with a movable notch 15 for the insertion block 35 to move. The stepped structure includes a first step 32 and a second step 33 sequentially provided at the top of the top frame 31. When the bottom frame 11 is connected to the top frame 31, the first step 32 abuts against the bottom of the connecting flange 14, and the second step 33 engages with the inner surface of the connecting flange 14. The movable notch 15 at the connecting flange 14 at the bottom edge of the bottom frame 11 allows the insertion block 35 to move within the movable notch 15, ensuring that the insertion block 35 is smoothly inserted into the assembly block 2. The groove 21 is used to combine the top frame 31 and the bottom frame 11. When the bottom frame 11 is connected to the top frame 31, the first step 32 of the top frame 31 abuts against the bottom of the connecting flange 14, which can support the top frame 31 from below and prevent the top frame 31 from excessively displacing in the horizontal direction. At the same time, the second step 33 of the top frame 31 engages with the inner surface of the connecting flange 14, which further enhances the tightness and stability of the connection between the top frame 31 and the bottom frame 11. This makes the connection between the boxes 7 more stable and reliable when several boxes 7 are vertically spliced ​​together, and improves the overall strength and stability of the entire box 7 splicing structure.

[0052] refer to Figure 1 and Figure 2 In this embodiment, more specifically, the upper two sides of the bottom frame 11 are provided with first corner frames 16 for supporting the bottom corners of the box 7, and the lower two sides of the top frame 31 are provided with second corner frames 36 for supporting the top corners of the box 7. This is for the stable assembly of several boxes 7. The first corner frames 16 on the upper two sides of the bottom frame 11 can support the bottom corners of the box 7, and the second corner frames 36 on the lower two sides of the top frame 31 can support the top corners of the box 7. This support structure can disperse the external force on the box 7 during assembly, reduce stress concentration at the corners, and thus ensure that the position of each box 7 is relatively fixed when several boxes 7 are assembled, avoiding shaking or displacement due to external forces, and improving the stability of the assembly of several boxes 7.

[0053] refer to Figure 2 and Figure 3 In this embodiment, more specifically, the extension of the insert 35 near the slot 21 has a locking block 37. After the insert 35 is inserted into the slot 21, the bottom protrusion of the locking block 37 engages with the assembly block 2. After the insert 35 is inserted into the slot 21, the bottom protrusion of the extended locking block 37 can engage with the assembly block 2. This engagement structure can effectively restrict the insert 35 from coming out of the slot 21, enhance the stability of the connection between the insert 35 and the assembly block 2, and thus improve the stability of the combination of the top frame 31 and the bottom frame 11, ensuring that the connection of several boxes 7 is more reliable when they are assembled in the vertical direction.

[0054] refer to Figure 2 In this embodiment, more specifically, a pin hole 38 is provided in the locking groove 34, and a limiting hole 39 is provided in the insert block 35. When the pin hole 38 and the limiting hole 39 coincide, the pin is inserted into the pin hole 38 and the limiting hole 39 to limit the insert block 35 in the locking groove 34, so that the insert block 35 is stably kept in the current position, preventing the insert block 35 from sliding or falling out at will, thereby ensuring the stability of the connection between the top frame 31 and the bottom frame 11, and thus ensuring the reliability of the vertical splicing and combination structure of several boxes 7.

[0055] refer to Figure 4 In this embodiment, more specifically, several boxes 7 are combined and arranged, and quick-release holes are provided on both sides of the bottom frame 11 of the bottom connecting component 1 at the bottommost box 7, and universal wheels 6 are provided corresponding to the quick-release holes for moving the assembled box 7.

[0056] The implementation principle of a protective connection mechanism for a housing 7 according to an embodiment of this application is as follows: This protective connection mechanism for housing 7 achieves vertical assembly of housing 7 through the coordinated action of the bottom connecting component 1, the assembly block 2, and the top connecting component 3; the bottom connecting component 1 and the top connecting component 3 reinforce and connect the bottom and top of housing 7, while the assembly block 2 ensures a reliable connection between the upper and lower housing 7; the connection method between each component is stable and reliable, improving the stability and accuracy of housing 7 assembly, and effectively avoiding the defects of existing connection methods, such as loose connections and insufficient strength; at the same time, this connection mechanism is relatively simple to operate, easy to install and disassemble, and can improve the efficiency of housing 7 assembly and reduce costs.

[0057] Example 2, reference Figures 5-7 The difference between this embodiment and Embodiment 1 is that: a bearing block 4 is provided in the locking groove 34 above the insert block 35, a swing groove 41 is provided at the bottom of the bearing block 4, a swing rod 42 is rotatably provided in the swing groove 41, a limit block 43 is provided at the bottom of the swing rod 42, the bottom corner of the limit block 43 is set as an arc surface 46, the limit block 43 is set in the limit hole 39, and is used to limit the insertion block 35. The limit block 43 at the bottom of the swing rod 42 rotating in the swing groove 41 can be placed in the limit hole 39 of the insertion block 35. After the top frame 31 and bottom frame 11 are combined by inserting into the slot 21 of the assembly block 2, the swing rod 42 can rotate in the swing groove 41 to allow the limiting block 43 to enter the limiting hole 39, thereby limiting the insertion block 35 from above and preventing the insertion block 35 from coming out of the slot 21. By making the corner edge of the limiting block 43 an arc surface 46, it is avoided that the limiting block 43 will collide with the end face of the insertion block 35 when it swings into the limiting hole 39, which effectively improves the stability of the combination of the top frame 31 and bottom frame 11, and thus ensures the stability of the vertical splicing combination structure of multiple boxes 7.

[0058] refer to Figure 6 In this embodiment, more specifically, a baffle 44 is rotatably provided on the axial end face of the bearing block 4 corresponding to the opening of the swing groove 41. This baffle 44 is used to block the swing rod 42 when the insert block 35 is limited, preventing the swing rod 42 from swinging in the axial direction of the insert block 35. This allows the limiting block 43 to limit the insert block 35 within the limiting hole 39. When the insert block 35 is limited, the baffle 44 rotatably provided on the axial end face of the bearing block 4 corresponding to the opening of the swing groove 41 will block the swing rod 42. When the swing rod 42 rotates within the swing groove 41 and the limiting block 43 is placed within the limiting hole 39 of the insert block 35, the baffle 44 can prevent the swing rod 42 from swinging in the axial direction of the insert block 35, thereby ensuring that the limiting block 43 can remain stably within the limiting hole 39. This effectively limits the insertion block 35, ensuring that the position of the insert block 35 within the locking groove 34 is fixed, thus improving the stability and reliability of the entire connection mechanism.

[0059] refer to Figure 6 In this embodiment, more specifically, elastic elements 45 are provided on both sides of the limiting block 43. The elastic elements 45 are made of elastic rubber pads and are in contact with the inner wall of the limiting hole 39 to increase the connection stability between the insert block 35 and the limiting block 43. When the insert block 35 is inserted into the slot 21 and the limiting block 43 is placed in the limiting hole 39, the elastic element 45 will undergo elastic deformation to generate elastic force acting on the inner wall of the limiting hole 39. This elastic force can fill the gap that may exist between the limiting block 43 and the limiting hole 39, reduce the relative shaking and displacement between the two, thereby effectively increasing the connection stability between the insert block 35 and the limiting block 43, and thus ensuring the structural stability of the entire housing 7 protection connection mechanism.

[0060] Example 3, reference Figures 8-11The difference between this embodiment and Embodiment 1 is that it further includes an overlapping assembly 5 for the lateral combination of several boxes 7. The overlapping assembly 5 includes several overlapping pieces 51 for the lateral splicing of adjacent boxes 7 and disposed outside the second corner frame 36. The end face of the overlapping piece 51 is provided with a frame 52, one frame 52 is provided with a connecting rod 53, and a threaded cylinder 54 is rotatably and slidably disposed on the connecting rod 53. The other frame 52 is provided with a threaded rod 55, and the inner wall of the threaded cylinder 54 is threadedly connected to the outer surface of the threaded rod 55. The overlapping assembly 5 can realize the lateral combination of several boxes 7; specifically, the overlapping pieces 51 disposed outside the second corner frame 36 are... The overlapping piece 51 is used for the lateral splicing of adjacent boxes 7. The frame 52 on the end face of the overlapping piece 51 is respectively provided with connecting rod 53 and threaded rod 55. When the boxes 7 are spliced ​​laterally, the threaded rod 55 on another frame 52 follows the laterally moving box 7 and splices with the initial box 7. After being placed side by side, the threaded rod 55 and the connecting rod 53 on one of the frames 52 of the initial box 7 are at the same horizontal position, and are threadedly combined with the threaded rod 55 by sliding and rotating the threaded cylinder 54. Due to the threaded engagement, adjacent boxes 7 can move closer or further away from each other, thereby completing the lateral splicing combination, effectively improving the convenience and stability of the lateral connection of multiple boxes 7.

[0061] refer to Figure 11 In this embodiment, more specifically, the head of the connecting rod 53 is provided with a fixing plate 56, which is disposed inside the threaded cylinder 54 and is used to limit the sliding of the threaded cylinder 54. When the threaded cylinder 54 rotates and slides on the connecting rod 53, the fixing plate 56 will restrict the threaded cylinder 54 from continuing to slide towards the head of the connecting rod 53, preventing the threaded cylinder 54 from coming off the connecting rod 53, thereby effectively limiting the sliding of the threaded cylinder 54 and ensuring that the overlapping assembly 5 can work stably during the lateral assembly of several boxes 7, making the lateral splicing of adjacent boxes 7 more reliable.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
