Description

Technical Field

[0001] This application relates to the field of storage and transportation boxes, and more particularly to a box connection structure. Background Technology

[0002] The box-type connection structure is a structure that connects multiple independent and hollow box-type components together using appropriate connection methods (such as bolt fastening, welding fusion, etc.) according to actual needs, thereby forming an overall structure that can meet specific usage requirements and has sufficient strength and stability.

[0003] Traditional box connection structures usually require locking the box cover and connecting the box separately, which is cumbersome and makes it difficult to quickly assemble or disassemble multiple boxes. In addition, the stacking stability is poor and it is easy to slide or collapse. Utility Model Content

[0004] To address the problem of traditional enclosures being difficult to assemble or disassemble quickly, this application provides an enclosure connection structure.

[0005] The box connection structure provided in this application adopts the following technical solution:

[0006] A box-type connection structure includes a box body and a box cover at the top of the box body. A connecting plate is symmetrically arranged at the bottom of the box body. A locking block is symmetrically fixed to one side of the upper end of the box body. Fixing plates are fixed to both sides of the locking blocks on the box body. Fixing blocks are fixed to the opposite sides of the two fixing plates on the box body. A latch is rotatably arranged between the upper end of each fixing plate and the fixing block. A fixing rod is rotatably arranged at the upper end of the latch, engaging with the extension of the connecting plate. A fixing block is fixed to one side of the box cover. A locking buckle is rotatably arranged in the middle of the fixing block, engaging with the lower end of the locking block. Multiple boxes are connected end-to-end by the self-locking engagement of the bottom connecting plate, the latch on one side, and the fixing rod.

[0007] By adopting the above technical solution, the device facilitates connection and fixation with other components and stacking of multiple boxes through the connecting plate at the bottom of the box; the locking block and the corresponding latch on the lid engage with each other to achieve initial locking of the box and lid; the fixing plate and fixing block provide rotational support for the latch, and the fixing rod at the upper end of the latch engages with the extension of the connecting plate, which facilitates the rapid stacking and assembly of multiple boxes, while further locking the box and lid, enhancing the stability of the connection between the box and lid.

[0008] Preferably, the surface of the connecting plate is provided with mounting holes, the shape of the connecting plate is adapted to the bottom of the box and one end extends out of the outer side of the bottom surface of the box, and the connection with the bottom of the box is achieved by bolts passing through the mounting holes.

[0009] By adopting the above technical solution, the connecting plate is designed to fit the shape of the bottom of the box and extend to the outer side of the bottom surface of the box. With the help of surface mounting holes, the connecting plate is fixed to the bottom of the box by bolts passing through the mounting holes, which facilitates the subsequent connection with other components to achieve the assembly between the boxes.

[0010] Preferably, the upper end of the opposite side of the fixing plate is fixed to both ends of the locking block, and a gap is left between the fixing plate and the fixing block for the rotational connection of the buckle.

[0011] By adopting the above technical solution, the cooperation between the fixing plate, the locking block, and the fixing block three provides space for the buckle rotation connection, ensuring that the buckle can rotate flexibly to realize the locking and opening operations of the box body and the box lid.

[0012] Preferably, the upper end of the buckle is provided with a circular hole six and a circular hole five, the middle part of the fixing rod rotates through the circular hole six, and the two sides of the buckle are provided with limiting grooves for limiting the fixing rod after rotation.

[0013] By adopting the above technical solution, the circular hole six cooperates with the fixed rod, which facilitates the flexible rotation of the fixed rod. The limiting grooves on both sides of the buckle can effectively limit the fixed rod after rotation, so that when the fixed rod is reversed, it can be easily inserted into the limiting groove and stored.

[0014] Preferably, the fixing block is composed of multiple arrays of wedge-shaped blocks, and the upper end of the latch is provided with multiple racks that mesh with the wedge-shaped block array of the fixing block. The upper end of the latch and the middle part of the fixing block are rotatably connected by a rotating shaft.

[0015] By adopting the above technical solution, the fixing block one engages with multiple racks at the upper end of the latch, and under the through rotation of the rotating shaft one, the latch rotates flexibly. The engagement of the wedge block and the racks achieves a stable connection, enhancing the reliability of the connection between the lid and the box body.

[0016] Preferably, the top of the box cover is symmetrically provided with placement slots adapted to the shape of the connecting plate, which are used to accommodate the connecting plate at the bottom of another box when multiple boxes are assembled and stacked.

[0017] By adopting the above technical solution, the placement slot is used to accommodate the connecting plate at the bottom of another box when multiple boxes are assembled and stacked, effectively preventing the boxes from shifting or shaking when stacked, and ensuring the stability of the overall structure.

[0018] Preferably, the upper end of the card block has a convex shape and the lower end has a wedge-shaped protrusion. The box cover is fixed to the bottom end of the fixing block one with a fixing block two. The bottom end of the fixing block two has a concave shape, and the shape of the lower end is adapted to the shape of the upper end of the card block to achieve engagement.

[0019] By adopting the above technical solution, the design of the upper convex shape and the lower wedge-shaped protrusion of the card block, together with the fixed block with the concave shape at the bottom of the lid and the matching shape at the bottom, can quickly connect the lid and the box body through the interlocking action, effectively preventing the lid from accidentally detaching from the box body.

[0020] Preferably, the upper end of the fixing plate is provided with a circular hole two, the middle part of the fixing block three is provided with a circular hole three coaxial with the circular hole two, a rotating shaft two is fixedly provided through the circular hole two and the circular hole three, the buckle is rotated and sleeved on the middle part of the rotating shaft two through the circular hole five, and the middle part of the fixing plate is provided with an movable hole to provide clearance space when the buckle rotates.

[0021] By adopting the above technical solution, the cooperation of circular hole two, circular hole three, and rotating shaft two provides a stable rotation axis for the buckle. The movable hole in the middle of the fixing plate provides the necessary clearance space for the buckle to rotate, ensuring smooth buckle rotation and ensuring convenient opening and closing of the lid and the box body, and a stable connection.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This device uses a downward rotating buckle centered on a rotating shaft to engage the wedge-shaped groove at the lower end of the buckle with the wedge-shaped protrusion at the lower end of the locking block, thus locking the lid and the box body. An upward rotating buckle causes the fixing rod to rotate around a rotating shaft, allowing the U-shaped end of the fixing rod to engage with the extension of the connecting plate at the bottom of the upper box body. Pressing down the buckle tightens the upper and lower boxes, achieving rapid assembly and fixing between the boxes and secondary locking of the lid. This results in simple operation, a stable connection, and reliable anti-loosening. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Figure 9 This application will be described in further detail.

[0037] This application discloses a box connection structure.

[0038] Reference Figure 1 - Figure 9 A box-type connection structure includes a box body 1 and a box cover 2 at the top of the box body 1. The box cover 2 is used to seal the box body 1. A mounting groove 23 is symmetrically formed at the bottom of the box body 1. Multiple symmetrical threaded holes 24 are equally spaced along the length of the bottom of the mounting groove 23 at the center of the groove. A connecting plate 3 is installed inside the mounting groove 23. Multiple symmetrical mounting holes 18 are formed on the surface of the connecting plate 3. The position and number of mounting holes 18 correspond to the position and number of threaded holes 24. The shape of the connecting plate 3 is adapted to the shape of the mounting holes 18. The shape of the connecting plate 3 (e.g., ...) Figure 8 As shown, the connecting plate 3 is threaded through the mounting holes 18 on the surface of the connecting plate 3 by multiple bolts and threaded into the threaded holes 24, so that the two connecting plates 3 are symmetrically installed at the bottom of the box 1, and one end of the connecting plate 3 extends out of the outer side of the bottom surface of the box 1.

[0039] Before using the device, the connecting plate 3 needs to be embedded into the mounting groove 23 symmetrically opened at the bottom of the box 1, so that the mounting hole 18 corresponds one-to-one with the multiple threaded holes 24 in the middle of the bottom of the mounting groove 23, and the bolt is inserted into the threaded hole 24 through the mounting hole 18 to achieve symmetrical installation of the connecting plate 3 at the bottom of the box 1.

[0040] A locking block 11 is symmetrically arranged on one side of the upper end of the housing 1. The upper end of the locking block 11 is convex, and the lower end of the locking block 11 is provided with a wedge-shaped protrusion with an angle of 15°. The shape of the locking block 11 is as follows (e.g., Figure 4 As shown), the housing 1 has fixing plates 12 fixed on both sides of the locking block 11. The upper ends of the opposite sides of the two fixing plates 12 are fixed to the two ends of the locking block 11, respectively. The shape of the fixing plates 12 is as follows (e.g., Figure 4 As shown), a circular hole 15 is provided at the upper end of the fixing plate 12, and a movable hole 14 is provided in the middle of the fixing plate 12. A fixing block 16 is fixed on the opposite side of the two fixing plates 12. The shape of the fixing block 16 is as follows (as shown). Figure 4 As shown), a circular hole 17 is provided in the middle of the fixing block 16. The center line of the circular hole 17 is on the same horizontal line as the center line of the circular hole 15. There is a gap between the fixing block 16 and the fixing plate 12.

[0041] The upper ends of the two fixing plates 12 located on both sides of the locking block 11 are rotatably provided with buckles 5, the shape of which is (e.g.) Figure 8 As shown), the upper end of the latch 5 has circular holes 20 on both sides. Near the circular holes 20, a circular hole 21 is located at the upper end of the latch 5, directly below the circular holes 20. A rotating shaft 8 is rotatably inserted through the center of the circular holes 20. The two ends of the rotating shaft 8, located outside the circular holes 20, are fixedly inserted into the interiors of the circular holes 25 and 37, respectively. Two fixing blocks 3 16 are inserted between the upper ends of the two fixing plates 12 on both sides of the upper end of the latch 5. A fixing rod 6 is rotatably installed inside the two circular holes 21. The fixing rod 6 is a U-shaped hanging ring. The length of the straight arm section of the fixing rod 6 matches the thickness of the extension of the connecting plate 3. The shape of the fixing rod 6 (as shown) Figure 8 (As shown).

[0042] Then, insert the upper sides of the buckle 5 into the gap between the upper end of the fixing block 3 16 and the upper end of the fixing plate 12, and pass through the circular hole 5 20 at the upper end of the buckle 5 through the rotating shaft 2 8 and fix both ends in the circular hole 2 15 and the circular hole 3 17 to complete the rotational connection of the buckle 5; then pass through the circular hole 6 21 at the upper end of the buckle 5 through the lower end of the fixing rod 6, so that its upper end is locked in the extension part of the connecting plate 3 at the bottom end of the box 1.

[0043] The lower end of the fixing rod 6 passes through the circular hole 21, and the upper end of the fixing rod 6 is engaged with the extension of the connecting plate 3 at the bottom of the box 1. Limiting grooves 22 are provided on both sides of the buckle 5. The shape of the limiting grooves 22 matches the shape of the fixing rod 6, so that when the fixing rod 6 rotates 180 degrees in the circular hole 21, both sides of the fixing rod 6 engage with the limiting grooves 22. A fixing block 9 is symmetrically fixed on one side of the box cover 2. The fixing block 9 is composed of multiple arrayed wedge-shaped blocks, and the shape of the fixing block 9 (e.g., ...) is... Figure 4As shown), the fixing block 9 is located directly above two fixing plates 12 on one side of the box body 1. The length of the fixing block 9 is the same as the distance between the opposite sides of the two fixing plates 12. A circular hole 13 is provided in the middle of the fixing block 9.

[0044] Insert the upper end of the latch 4 on the cover 2 into the middle of the fixing block 9. The rotating shaft 7 passes through the circular hole 19 and is fixed to the outer walls of the two sides of the fixing block 9. The lower end of the fixing block 10 engages with the convex structure on the upper end of the card block 11. The wedge-shaped groove at the lower end of the latch 4 matches the wedge-shaped protrusion at the lower end of the card block 11, forming a self-locking engagement, thus completing the overall installation preparation.

[0045] A second fixing block 10 is fixed directly below the first fixing block 9 on the lid 2. The bottom end of the second fixing block 10 is U-shaped, and the shape of the lower end of the second fixing block 10 matches the shape of the upper end of the locking block 11. The lower end of the second fixing block 10 engages with the upper end of the locking block 11. A latch 4 is rotatably installed in the middle of the first fixing block 9. Multiple racks are provided on the upper end of the latch 4. The racks engage with the wedge-shaped block array of the first fixing block 9, so that the upper end of the latch 4 is inserted into the middle of the first fixing block 9. The shape of the latch 4 (as shown in the figure) Figure 8 , Figure 9 As shown), the upper end of the latch 4 has a circular hole 19, the diameter of which is the same as the diameter of the circular hole 13, and a rotating shaft 7 is movably inserted through the interior of the circular hole 19.

[0046] The two ends of the rotating shaft 7 located outside the circular hole 19 are fixed and pass through the outer walls of the two sides of the fixing block 9. The length of the latch 4 is the same as the length of the locking block 11. The latch 4 rotates around the rotating shaft 7 in the middle of the fixing block 9. The middle of the latch 4 is adapted to the shape of the locking block 11. A wedge-shaped groove is provided in the middle of the side of the latch 4 near the locking block 11. The angle of the wedge-shaped groove is 15°. The shape of the wedge-shaped groove is adapted to the shape of the wedge-shaped protrusion at the lower end of the locking block 11, so that the lower end of the locking block 11 is engaged with the lower end of the latch 4 near the side of the locking block 11.

[0047] When in use, when the lid 2 and the body 1 are closed, the concave structure at the lower end of the fixing block 10 engages with the convex structure at the upper end of the locking block 11 to achieve the initial positioning of the lid 2 and the body 1. The locking buckle 4 rotates around the rotating shaft 7 in the middle of the fixing block 9, so that the wedge-shaped groove at the lower end of the locking block 11 forms a self-locking engagement with the wedge-shaped protrusion at the lower end of the locking block 11.

[0048] On the upper end of the box body 1, on both sides adjacent to the two locking blocks 11, and on both sides of the box cover 2, locking blocks 11 and fixing blocks 9 are set as needed to further fix the box body 1 and the box cover 2. The top of the box cover 2 is symmetrically provided with placement grooves 25. The shape of the placement grooves 25 is adapted to the shape of the connecting plate 3, and is used to accommodate the connecting plate 3 at the bottom of another box body 1 when multiple boxes 1 are assembled and stacked.

[0049] Due to the fit between the connecting plate 3 and the mounting groove 23 and the threaded connection between the bolt and the threaded hole 24, by rotating the buckle 5 upward between the fixing plate 12 and the fixing block 16 via the rotating shaft 28, the fixing rod 6 is rotated 180 degrees around the circular hole 6 21 as the rotation center, so that the upper end of the U-shaped straight arm section is inserted into the connecting plate 3 at the bottom extension of the box 1. Then, the buckle 5 is pressed to make the buckle 5 flip downward to fit against the side of the box 1, thus completing the combination and fixation between the box 1 and the box 2, and at the same time, further locking the box 1 and the box cover 2.

[0050] The implementation principle of the box connection structure in this application embodiment is as follows: When the device is in use, by closing the box cover 2 and the box body 1, the lower end of the fixing block 10 and the upper end of the locking block 11 are engaged to achieve initial positioning. The latch 4 is flipped downward around the rotating shaft 7, so that the lower end of the latch 4 and the lower end of the locking block 11 form a self-locking engagement. The connecting plate 3 is installed in the mounting groove 23 by bolts and threaded connection of the threaded hole 24. The latch 5 is flipped upward around the rotating shaft 8, which drives the fixing rod 6 to rotate 180 degrees and engage with the extension of the connecting plate 3. Then the latch 5 is flipped downward to complete the fixation between the box body 1 and the box cover 2 and the secondary locking of the box body 1 and the box cover 2.

[0051] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
