Description

Tool-free quick-assembly container structure Technical Field

[0001] This utility model relates to the technical field of container manufacturing, and in particular to a tool-free quick-assembly container structure. Background Technology

[0002] In the wave of globalization, the logistics and transportation industry has flourished, with containers, as the core carrier of cargo transportation, being widely used in sea and land transportation. Meanwhile, in the construction sector, containers are also being extensively converted into temporary offices and residences. Both cargo transportation and the construction of temporary buildings place high demands on the ease of assembly and disassembly of containers.

[0003] However, existing container structures have the following shortcomings in practical use: During container assembly, components such as support columns, crossbeams, side beams, and corner fittings are generally made of steel, aluminum alloys, etc., making these parts bulky and heavy. The currently prevalent screw connection method poses a significant challenge to installation. During installation, installers must expend considerable physical strength to support the heavy parts, ensuring precise alignment of the screw holes on both parts; simultaneously, they must operate screwdrivers, wrenches, and other tools with one hand to tighten the screws. This places stringent demands on the installers' physical strength and operational skills. Furthermore, the excessive weight of the parts and prolonged support can easily lead to fatigue, further reducing installation efficiency and increasing installation difficulty. Therefore, this application proposes a tool-free, quick-assembly container structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tool-free quick-assembly container structure that reduces installation difficulty and improves installation efficiency.

[0005] The purpose of this utility model is achieved through the following technical solution: a tool-free quick-assembly container structure, including several crossbeams, several side beams and several support columns, wherein any adjacent crossbeam, side beam and support column are connected by a splicing component;

[0006] The splicing assembly includes corner pieces and several snap-fit ​​pieces. One end of each snap-fit ​​piece is connected to the corner piece, and the other end of each snap-fit ​​piece is connected to the crossbeam / the side beam / the support column.

[0007] The snap-fit ​​component includes a sleeve, a pin, and a locking element. The sleeve is disposed on the crossbeam / side beam / support column. The sleeve has a insertion hole and a locking hole. The insertion hole extends through both ends of the sleeve, and the locking hole extends through the two opposite sides of the sleeve, so that the insertion hole and the locking hole are connected in a cross shape. The crossbeam has a through hole, and the through hole is coaxially connected to the locking hole. The pin is disposed on the corner piece, and the pin has a through hole. The corner piece drives the pin to be inserted into the insertion hole so that the through hole, the locking hole, and the through hole are connected to form a pin hole. The locking element passes through the pin hole to allow the crossbeam and the corner piece to be quickly connected.

[0008] Optionally, the sleeve is provided with a locking platform, which is located on the inner side wall of the lock hole. The locking member is provided with a locking groove, which is opened along the circumferential direction of the locking member, and the locking groove engages with the locking platform.

[0009] Optionally, the sleeve is further provided with a plurality of toothed grooves, each of which is located on the inner sidewall of the lock hole and is equidistant from each other. Any one of the toothed grooves engages with the locking member so that the rotation angle of the locking member is adjustable.

[0010] Optionally, the locking component includes a pin, a first circular block, a second circular block, and a swing block. The first circular block and the second circular block are coaxially disposed at both ends of the pin. The swing block is disposed on the side of the second circular block away from the pin. The slot is formed on the outer wall of the first circular block and engages with the locking platform.

[0011] Optionally, the pin has an elliptical structure.

[0012] Optionally, the through hole has a square structure, and the side length of the through hole is greater than the length of the long axis of the cross-section of the pin.

[0013] Optionally, the locking component further includes a shaft, a top block, and an arc-shaped block. The shaft is coaxially inserted into the pin, and both ends of the shaft extend from both ends of the pin. The top block is disposed on one end of the shaft, and the arc-shaped block is rotatably disposed on the pin. The shaft drives the top block to abut against the arc-shaped block, so that one end of the arc-shaped block engages with any one of the toothed grooves.

[0014] Optionally, one end of the arc-shaped block is provided with a slanted locking part, which engages with any one of the toothed grooves.

[0015] Optionally, the locking element further includes a tension spring, the two ends of which are rotatably connected to the arc-shaped block and the top block, respectively.

[0016] Optionally, the locking element further includes a torsion block, which is rotatably disposed on the end of the shaft away from the top block, and the torsion block is used to drive the shaft to rotate relative to the pin.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] This utility model discloses a tool-free, quick-assembly container frame. It incorporates snap-fit ​​components between corner fittings and crossbeams / side beams / support columns. Each snap-fit ​​component includes a sleeve, a pin, and a locking mechanism. The sleeve is mounted on the crossbeam / side beam / support column, and the pin is mounted on the corner fitting. Operators simply need to insert the pin on the corner fitting into the sleeve on the crossbeam / side beam / support column, and then insert the locking mechanism into the locking holes and through holes on the sleeve and pin. This improves installation efficiency and reduces installation difficulty. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] As shown in Figures 1 to 10, in one embodiment, a tool-free quick-assembly container frame 1 includes several crossbeams 2, several side beams 3, and several support columns 4. Any adjacent crossbeam 2, side beam 3, and support column 4 are connected by a splicing structure 5. The splicing structure 5 includes corner pieces 60 and several snap-fit ​​components 50. One end of each snap-fit ​​component 50 is connected to the corner piece 60, and the other end of each snap-fit ​​component 50 is connected to the crossbeam 2 / side beam 3 / support column 4. The snap-fit ​​component 50 includes a sleeve 51, a pin 52, and a locking element 53. The sleeve 51 is disposed on the crossbeam 2 / side beam 3 / support column 4, and the sleeve 51 has an opening on it. The sleeve 511 is provided with a socket 511 and a lock hole 512. The socket 511 passes through both ends of the sleeve 51, and the lock hole 512 passes through the two opposite sides of the sleeve 51, so that the socket 511 and the lock hole 512 are connected in a cross shape. The crossbeam 2 has a through hole, which is coaxially connected to the lock hole 512. The insert 52 is provided on the corner piece 60, and the insert 52 has a through hole 521. The corner piece 60 drives the insert 52 to be inserted into the socket 511 so that the through hole 521, the lock hole 512 and the through hole are connected to form a pin hole. The locking member 53 is inserted into the pin hole so that the crossbeam 2 / side beam 3 / support column 4 is quickly connected to the corner piece 60.

[0039] It should be noted that the splicing structure 5 includes corner pieces 60 and several snap-fit ​​components 50. One end of each snap-fit ​​component 50 is connected to three adjacent sides of the corner piece 60, and the other end of each snap-fit ​​component 50 is connected to the crossbeam 2, side beam 3, and support column 4. A sleeve 51 is provided at the end of the crossbeam 2; for example, the sleeve 51 and the end of the crossbeam 2 are integrally formed. The sleeve 51 has an insertion hole 511 and a locking hole 512. The insertion hole 511 passes through both ends of the sleeve 51, and the locking hole 512 passes through the two opposing sides of the sleeve 51, so that the insertion hole 511 and the locking hole 512 are connected in a cross shape. Furthermore, the crossbeam 2 has a through hole that passes through the two opposing sides of the crossbeam 2. When the sleeve 51 is placed inside the end of the crossbeam 2, the through hole is coaxially connected to the locking hole 512. Furthermore, one end of the insert 52 is disposed on one side of the corner piece 60, for example, the insert 52 and the corner piece 60 are integrally formed. A through hole 521 is provided on the insert 52, perpendicular to the axis of the insert 52. When the corner piece 60 drives the insert 52 into the insertion hole 511, the through hole 521 is coaxially connected to the locking hole 512 and the through hole, thus forming a pin hole together with the through hole and the locking hole 512. Furthermore, a locking member 53 passes through the pin hole, with both ends of the locking member 53 located on either side of the insert 52, preventing the insert 52 from being pulled out of the insertion hole 511. This allows the crossbeam 2 and the corner piece 60 to be quickly connected, enabling tool-free quick installation.

[0040] As shown in Figures 4 to 8, in one embodiment, the sleeve 51 is provided with a locking platform 513, which is located on the inner side wall of the lock hole 512. The locking member 53 is provided with a locking groove 5321, which is opened along the circumferential direction of the locking member 53, and the locking groove 5321 engages with the locking platform 513.

[0041] It should be noted that the insertion hole 511 penetrates both ends of the sleeve 51, and the locking hole 512 penetrates the two opposing sides of the sleeve 51, making the insertion hole 511 and the locking hole 512 connected in a cross shape. This allows the locking hole 512 to be divided into a first locking hole and a second locking hole with the insertion hole 511 as the center. The locking platform 513 is disposed on the inner wall of the first locking hole, and the locking platform 513 is arranged along the circumferential direction of the inner wall of the first locking hole. Furthermore, a locking groove 5321 is provided on one end of the locking member 53, and the locking groove 5321 is opened along the circumferential direction of the locking member 53. The operator inserts the locking member 53 into the pin hole from one end of the second locking hole. The locking member 53 drives the locking groove 5321 from the second locking hole into the first locking hole. Rotating the locking member 53 causes the locking groove 5321 to engage with the locking platform 513 in a circumferential direction. This prevents the locking member 53 from sliding out along the axial direction of the pin hole.

[0042] As shown in Figures 6 and 7, in one embodiment, the sleeve 51 is also provided with a plurality of toothed grooves 514, each toothed groove 514 being located on the inner sidewall of the lock hole 512, and each toothed groove 514 being equidistantly distributed. Any toothed groove 514 can engage with the locking member 53 so that the rotation angle of the locking member 53 is adjustable.

[0043] It should be noted that each toothed groove 514 is located on the inner wall of the first locking hole, between the end face of the sleeve 51 and the locking platform 513, and each toothed groove 514 is connected to the end face of the sleeve 51. Each toothed groove 514 is squarely formed along the circumference of the inner wall of the first locking hole. A slanted locking portion 5371 is provided on the circumferential surface of the locking member 53 near the end of the first locking hole. When the locking member 53 is rotated relative to the first locking hole by an external force, the locking member 53 causes the slanted locking portion 5371 to engage with any one of the toothed grooves 514. Furthermore, each tooth groove 514 is a helical tooth structure, and each tooth groove 514 faces the same direction. For example, each tooth groove 514 faces clockwise, so that the locking member 53 can only drive the helical locking part 5371 to engage with any tooth groove 514 in a clockwise direction, thereby making the locking member 53 only able to rotate in one direction, and making the rotation angle of the locking member 53 adjustable.

[0044] As shown in Figures 8 and 9, in one embodiment, the locking member 53 includes a pin 531, a first circular block 532, a second circular block 533, and a swing block 534. The first circular block 532 and the second circular block 533 are coaxially disposed at both ends of the pin 531, and the swing block 534 is disposed on the side of the second circular block 533 away from the pin 531. A slot 5321 is formed on the outer side wall of the first circular block 532 and engages with the locking platform 513.

[0045] It should be noted that both the first circular block 532 and the second circular block 533 are cylindrical structures, while the pin 531 is elliptical. The pin 531 has vertical portions at both ends of its cross-section's major axis, and these two vertical portions are parallel to each other. When the pin 531 is inserted into the through hole 521, the first circular block 532 and the second circular block 533 are coaxially located at the ends of the lock hole 512 and the through hole, respectively. Furthermore, the length of the major axis of the pin 531's cross-section is less than the diameter of the first circular block 532 / second circular block 533. This causes the first circular block 532 and the second circular block 533 to rotate around the axes of the lock hole 512 and the through hole, simultaneously causing the pin 531 to rotate around the axis of the through hole 521.

[0046] It should be noted that the through hole 521 on the insert 52 has a square structure, and the side length of the through hole 521 is greater than the distance between the two long axis sides of the pin 531, allowing the pin 531 to rotate within the through hole 521. Furthermore, when the inner sidewall of the through hole 521 away from the corner piece 60 abuts against the long axis side of the pin 531, the axis of the through hole 521 is misaligned with the axis of the locking hole 512 / through hole 521, causing the insert 52 to move the corner piece 60 away from the crossbeam 2 / side beam 3 / support column 4, thus creating a gap between the corner piece 60 and the crossbeam 2 / side beam 3 / support column 4. This facilitates the installation of the enclosure panels in the tool-free quick-assembly container structure 1 of this application to form the container body.

[0047] It should be noted that the swing block 534 is located on the end of the second circular block 533 away from the pin 531, and the swing block 534 extends from the surface of the crossbeam 2 / side beam 3 / support column 4. After the enclosure is installed, the operator can rotate the swing block 534 so that the swing block 534 drives the second round block 533 to rotate around the axis of the lock hole 512 and the through hole. This causes the outer side of the pin 531 to rotate and abut against the inner side wall of the through hole 521 away from the corner piece 60. When the side of the pin 531 that is rotating to the long axis of the cross section abuts against the inner side wall of the through hole 521, the pin 531 pushes the through hole 521 so that the through hole 521 is coaxially connected with the lock hole 512 and the through hole. This causes the insert 52 to drive the corner piece 60 to move closer to the crossbeam 2 / side beam 3 / support column 4 to close the gap between the corner piece 60 and the crossbeam 2 / side beam 3 / support column 4, so that the crossbeam 2, side beam 3 and support column 4 together clamp the enclosure.

[0048] It should be noted that the slot 5321 is formed on the outer wall of the first circular block 532, and the slot 5321 is formed along the circumference of the first circular block 532. The pin 531, the first circular block 532, and the second circular block 533 are all inserted into the pin hole. The swing block 534 drives the second circular block 533 to rotate relative to the pin hole, so that the second circular block 533 drives the pin 531 to rotate relative to the through hole 521, thereby causing the first circular block 532 to drive the slot 5321 to rotate around the axis of the through hole and engage with the locking platform 513. This prevents the pin 531 from being pulled out of the lock hole 512 / through hole / through hole 521. Furthermore, the slot 5321 has an L-shaped slot structure with a right angle between its two ends. One end of the slot 5321 is connected to the end face of the first circular block 532, so that one end of the slot 5321 is inserted into the slot platform 513 with the axis of the first circular block 532. When the first circular block 532 is rotated clockwise to make the slot platform 513 slide from one end of the slot 5321 along the circumferential direction to the other end of the slot 5321, so that the end face of the slot platform 513 abuts against the inner side wall of one end of the slot 5321, the long axis side of the pin 531 abuts against the inner side wall of the through hole 521 away from the corner piece 60. At this time, the first circular block 532 will not be able to rotate clockwise, so that one end of the long axis of the cross section of the pin 531 remains abutting against the inner side wall of the through hole 521 away from the corner piece 60.

[0049] As shown in Figures 9 and 11, in one embodiment, the locking member 53 further includes a shaft 535, a top block 536, and an arc-shaped block 537. The shaft 535 is coaxially inserted into the pin 531, and both ends of the shaft 535 extend from both ends of the pin 531. The top block 536 is disposed on one end of the shaft 535, and the arc-shaped block 537 is rotatably disposed on the pin 531. The shaft 535 drives the top block 536 to abut against the arc-shaped block 537, so that one end of the arc-shaped block 537 engages with any one of the toothed grooves 514.

[0050] It should be noted that the shaft 535 is coaxially inserted into the pin 531, the first circular block 532, and the second circular block 533, with both ends of the shaft 535 extending from the side of the first circular block 532 and the second circular block 533 away from the pin 531, respectively. The locking member 53 also includes a torsion block 538, which is rotatably disposed at one end of the shaft 535 and located outside the crossbeam 2 / side beam 3 / support column 4. Furthermore, the top block 536 is an irregularly shaped block, for example, an elliptical structure. The top block 536 is coaxially disposed on the end of the shaft 535 away from the torsion block 538, allowing the operator to rotate the torsion block 538 to rotate the top block 536 relative to the end face of the pin 531. Furthermore, the arc-shaped block 537 has an arc-shaped structure, with one end of each arc-shaped block 537 rotatably mounted on the side of the first circular block 532 away from the pin 531. The inclined locking portion 5371 is located on the end of the arc-shaped block 537 away from the first circular block 532, and is situated on the outer wall of the arc-shaped block 537. Further, one end of the arc-shaped block 537 extends to another section to form a ring-shaped structure; the diameter of the outer wall is consistent with the diameter of the lock hole 512. Two arc-shaped blocks 537 are provided, both facing each other along the circumferential direction of the side of the first circular block 532 away from the pin 531. Furthermore, when the pin 531 drives the top block 536 to rotate coaxially, the two ends of the long axis of the cross section of the top block 536 abut against the inner walls of the two arc-shaped blocks 537 respectively, and slide along the arc-shaped hole to the end of the arc-shaped block 537 near the first round block 532, so that the outer walls of the two arc-shaped blocks 537 coincide with the inner walls of the lock hole 512, thereby making the inclined locking parts 5371 on the two arc-shaped blocks 537 respectively engage with any two toothed grooves 514. When the first circular block 532 causes the end of the slot 5321 away from the end face to abut against the side of the mounting plate 513, preventing the pin 531 from continuing to rotate clockwise, the rotating shaft 535 drives the two ends of the top block 536 to push against the two arc-shaped blocks 537 respectively, so that the inclined locking parts 5371 on the two arc-shaped blocks 537 respectively engage with any two toothed grooves 514, thereby preventing the first circular block 532 from driving the pin 531 to rotate counterclockwise. In this way, one end of the long axis of the cross section of the pin 531 can remain in contact with the inner side wall of the through hole 521 away from the corner piece 60, thereby making the insert 52 drive the corner piece 60 to remain close to the crossbeam 2 / side beam 3 / support column 4.

[0051] As shown in Figures 6 to 7, 9 and 11, in one embodiment, the locking member 53 further includes a tension spring 539, the two ends of which are rotatably connected to the arc-shaped block 537 and the top block 536, respectively.

[0052] It should be noted that there are two tension springs 539. One end of each tension spring 539 is rotatably connected to the end of the inner wall of the arc block 537 near the inclined clamp 5371. The other end of each tension spring 539 is rotatably connected to the two short shaft sides of the top block 536. When the shaft 535 drives the two long shaft sides of the top block 536 away from the two arc blocks 537, the tension springs 539 on the two short shaft sides of the top block 536 simultaneously pull the two arc blocks 537, so that the two arc blocks 537 drive the two inclined clamps 5371 away from the tooth groove 514 simultaneously. When the shaft 535 drives the two long axis sides of the top block 536 to abut against the inner sidewalls of the two arc blocks 537 respectively, and slides from the end of the two arc blocks 537 near the first circular block 532 to the other end, so that the position where the two arc blocks 537 are rotatably connected to the tension spring 539 abuts against the two long axis sides of the top block 536 respectively, so that the long axis sides of the top block 536 stay at the end of the inner sidewall of the arc block 537 near the inclined clip 5371, thereby making the top block 536 continuously abut against the arc block 537.

[0053] As shown in Figures 6 to 7 and Figure 11, in one embodiment, the locking member 53 further includes a torsion block 538, which is rotatably disposed on the end of the shaft 535 away from the top block 536. The torsion block 538 is used to drive the shaft 535 to rotate relative to the pin 531.

[0054] It should be noted that one end of the torsion block 538 is rotatably mounted on the end of the second round block 533 away from the pin 531. When the axis of the torsion block 538 is perpendicular to the axis of the second round block 533, the operator can rotate the torsion block 538 to drive the first round block 532, the second round block 533, and the pin 531 to rotate around the axis of the pin hole. This allows the long axis side of the pin 531 to rotate and abut against or move away from the inner wall of the through hole 521. This allows the corner piece 60, together with the crossbeam 2 / side beam 3 / support column 4, to clamp or loosen the enclosure.

[0055] As shown in Figures 6, 9, and 10, in one embodiment, the first circular block 532, the second circular block 533, and the pin 531 are all coaxially formed with shaft holes and are interconnected. The shaft 535 passes through the shaft holes. One end of the swing block 534 is respectively located on both sides of the shaft hole on the second circular block 533 facing each other, while the end of the swing block 534 away from the second circular block 533 is perpendicular to the shaft hole, and the swing block 534 is located on the outer surface of the crossbeam 2 / side beam 3 / support column 4. Furthermore, the swing block 534 is provided with a clearance groove 5341. The width of the clearance groove 5341 is the same as the diameter of the shaft hole. When the shaft rod 535 passes through the shaft hole, when the torsion block 538 drives the top block 536 to abut against the arc-shaped block 537 through the shaft rod 535, the end of the torsion block 538 away from the shaft rod 535 can be rotated and accommodated in the clearance groove 5341. Thus, when the torsion block 538 is accommodated in the clearance groove 5341, the axis of the torsion block 538 is perpendicular to the axis of the shaft rod 535, and the torsion block 538 cannot drive the shaft rod 535 to rotate relative to the pin 531, thereby preventing the top block 536 from rotating, and thus causing the arc-shaped block 537 to disengage from the tooth groove 514.
