Description

Technical Field

[0001] This invention relates to the field of outdoor camping products, and more particularly to an expandable modular box. Background Technology

[0002] Patent publication CN211408060U discloses a mobile dining table for outdoor camping. This mobile dining table is essentially an expandable box. However, this box used as a mobile dining table is actually just two flat panels (labeled as 2b and 2C in the document) installed on the top of the box by hinges. Therefore, when used as a dining table, this type of box cannot be expanded in any direction according to its own needs, and its adaptability to outdoor use is relatively poor. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an extended splicing box.

[0004] The technical solution adopted in this invention is as follows:

[0005] An expandable splicing box includes several connecting pipes, several connectors, and a box panel. The connecting pipes and connectors are inserted together, and the connecting rods and connectors are joined together to form a hollow hexahedral box frame. The box panel is disposed on the box frame, and the connectors are located at the top corners of the box frame. It also includes an expansion joint, a transition joint, and an expansion connecting pipe. The connectors have mortises, the transition joints have mortises, and the expansion joints have tenons. The tenons are used to insert into the mortises, the transition joints are used to connect the expansion joints, and the two ends of the expansion connecting pipe are respectively joined to the expansion joints or connectors. The expansion connecting pipes form several clamping openings.

[0006] In this type of extended modular box, a box frame is first assembled using connectors and connecting pipes, and then the box panels are installed on the box frame using snap-fit ​​methods. Thus, a box is assembled using connecting pipes, connectors, and box panels. The box can be opened and closed by disassembling the box panels.

[0007] Similarly, in this type of expandable modular box, because the connector has a tenon groove and the connector is located at the top corner of the box frame (i.e., the connector is located at the top corner of the box frame), there are four perimeters at the top corner of the box frame where expansion joints can be connected. This means that expansion connecting pipes can be connected to all four sides of the box as needed, thereby forming clamping openings using the expansion connecting pipes. Ultimately, clamping openings can be formed in any direction around the perimeter of the box as needed, and different equipment can be placed in the clamping openings, such as a stove as shown in CN307953838S, or a shelf as shown in CN308099229S. Specifically, in this type of expandable modular box, the clamping openings formed by the expansion connecting pipes are rectangular.

[0008] In this type of expansion splicing box, two adjacent expansion connectors are connected to the same connector or transition connector. This ensures that the two adjacent expansion connectors remain stable, thereby ensuring that the two adjacent clamping ports remain stable.

[0009] Specifically, in this type of extended splicing box, the connecting pipes and extension connecting pipes are all hollow aluminum alloy pipes, which are both lightweight and have good rigidity.

[0010] Specifically, in this type of extended splicing box, the mortise is a square mortise and the tenon is a square tenon. The square mortise and the square tenon fit together to provide good stability.

[0011] Specifically, in this extended splicing box, the transition joint is in the shape of a square column, and four tenons are provided on the transition joint. The four tenons are located on the four side walls of the transition joint, so the transition joint can connect up to four extension joints. When the four extension joints are connected to the transition joint, the four extension joints are in a cross-shaped distribution.

[0012] Optionally, it may also include a support piece, which is disposed on the expansion connecting tube and located within the clamping opening.

[0013] The specific function of the support plate is to support the instrument placed in the clamping port, thereby ensuring that the instrument in the clamping port has high stability and load-bearing capacity.

[0014] Optionally, the support rod is inserted into the connector or transition joint, and the support rod is perpendicular to the extension connecting tube.

[0015] The specific function of the support rod is to contact the ground and thus provide support. When the support rod is inserted into the transition joint, the four tenons on the transition joint are distributed around the support rod.

[0016] Optionally, the expansion connector is provided with a socket, and the expansion connecting tube is inserted into the socket.

[0017] The socket on the expansion connector is used to insert the expansion connector tube. When the expansion connector tube is inserted into the socket of the expansion connector, the expansion connector tube is perpendicular to the tenon on the expansion connector, and the tenon and the expansion connector tube are located on opposite sides of the expansion connector.

[0018] Optionally, the connector is provided with a closed sleeve portion, a notched sleeve portion, and a bottom hole portion, and the tenon, the closed sleeve portion, and the notched sleeve portion are all arranged around the bottom hole portion.

[0019] Specifically, in this type of extended splicing box, the connector is square-column shaped, with a bottom hole at the center of the square-column connector. Two tenons, a closed sleeve, and a notched sleeve are respectively located on the four side walls of the connector. The closed sleeve, notched sleeve, and bottom hole can all be used to insert connecting pipes. The support rod is used to insert into the bottom hole, the closed sleeve is used to insert extending connecting pipes without support plates, and the notched sleeve is used to insert extending connecting pipes with support plates.

[0020] Specifically, in this splicing box, in order to improve the stability of the closed sleeve section and the notched sleeve section, a reinforcing rib is provided between the notched sleeve section and the connector, and a reinforcing rib is provided between the closed sleeve section and the connector.

[0021] Specifically, in this splicing box, both the closed sleeve section and the notched sleeve section are equipped with internal columns. The internal columns are used to fit tightly against the inner wall of the connecting pipe or the inner wall of the expansion connecting pipe, thereby improving the insertion stability of the connecting pipe and the expansion connecting pipe.

[0022] Specifically, in this type of splicing box, the socket of the expansion connector is also provided with an inner post, which is used to fit tightly against the inner wall of the expansion connection tube.

[0023] Optionally, an extension plate may also be included, which is disposed within the clamping opening.

[0024] The expansion plate is placed directly inside the clamping opening, and is supported by the support piece inside the clamping opening.

[0025] Optionally, a tie rod bracket is also included, which is mounted on the box frame.

[0026] Optionally, it also includes a rotating wheel, which is rotatably mounted on the box frame.

[0027] Optionally, it may also include a bracket, which is disposed on the box frame.

[0028] The beneficial effects of this invention are: expansion connecting pipes can be connected to all four sides of the box as needed, thereby forming clamping openings using the expansion connecting pipes, and finally, clamping openings can be formed in any direction around the box as needed.

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] As attached Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, an extended splicing box includes several connecting pipes 2, several connectors 1, and a box panel 3. The connecting pipes 2 and connectors 1 are inserted and fitted together. The connecting rods and connectors 1 are fitted together to form a hollow hexahedral box frame. The box panel 3 is set on the box frame, and the connectors 1 are located at the top corner of the box frame. It also includes an extension joint 8, a transition joint 9, and an extension connecting pipe 7. The connectors 1 and 9 have mortises 6. The extension joint 8 has tenons 801. The tenons 801 are used to insert and fit with the mortises 6. The transition joint 9 is used to connect the extension joint 8. The two ends of the extension connecting pipe 7 are fitted together with the extension joint 8 or the connectors 1, respectively. The extension connecting pipe 7 forms several clamping openings 701.

[0040] In this type of extended assembly box, a box frame is first assembled using connector 1 and connecting pipe 2, and then box panel 3 is installed on the box frame by means of snap fasteners. Thus, a box is assembled using connecting pipe 2, connector 1, and box panel 3. The box can be opened and closed by disassembling the box panel 3.

[0041] Similarly, in this type of extended assembly box, since the connector 1 is provided with a tenon 6, and the connector 1 is located at the top corner of the box frame (i.e., the connector 1 is located at the top corner of the box frame), there are four perimeters at the top corner of the box frame where extension connectors 8 can be connected. This means that extension connecting pipes 7 can be connected to all four perimeters of the box as needed, thereby forming clamping openings 701 using the extension connecting pipes 7. Ultimately, clamping openings 701 can be formed in any direction around the perimeter of the box as needed, and the clamping openings 701 can hold different equipment as needed, such as a stove as shown in CN307953838S, or a shelf as shown in CN308099229S. Specifically, in this type of extended assembly box, the clamping openings 701 formed by the extension connecting pipes 7 are rectangular.

[0042] In this type of expansion splicing box, two adjacent expansion connectors 8 are connected to the same connector 1 or transition connector 9. This ensures that the two adjacent expansion connectors 8 remain stable, thereby ensuring that the two adjacent clamping ports 701 remain stable.

[0043] Specifically, in this type of extended splicing box, both the connecting pipe 2 and the extended connecting pipe 7 are hollow aluminum alloy pipes, which are both lightweight and have good rigidity.

[0044] Specifically, in this type of extended splicing box, the mortise 6 is a square mortise 6, and the tenon 801 is a square tenon 801. The square mortise 6 and the square tenon 801 are interlocked together and have good stability.

[0045] As attached Figure 3 As shown, in this specific extended splicing box, the transition joint 9 is in the shape of a square column, and four tenons 6 are provided on the transition joint 9. The four tenons 6 are located on the four side walls of the transition joint 9 respectively. Therefore, the transition joint 9 can connect up to four extension joints 8. After the four extension joints 8 are connected to the transition joint 9, the four extension joints 8 are in a cross-shaped distribution.

[0046] As attached Figure 6 and 7 As shown, it also includes a support piece 702, which is disposed on the expansion connecting tube 7 and is located inside the clamping port 701.

[0047] Specifically, the function of the support plate 702 is to support the instrument placed in the clamping port 701, thereby ensuring that the instrument in the clamping port 701 has high stability and load-bearing capacity.

[0048] As attached Figure 1 , 2 As shown in Figures 3, 4, and 5, the support rod 5 is inserted and fitted together with the connector 1 or the transition connector 9, and the support rod 5 is perpendicular to the extension connecting pipe 7.

[0049] Specifically, the function of the support rod 5 is to contact the ground and thus provide support. When the support rod 5 is inserted into the transition joint 9, the four tenons 6 on the transition joint 9 are distributed around the support rod 5.

[0050] As attached Figure 3 and 8 As shown, the expansion connector 8 is provided with a socket 802, and the expansion connecting tube 7 is inserted into the socket 802.

[0051] Specifically, the socket 802 on the expansion connector 8 is used to insert the expansion connecting tube 7. When the expansion connecting tube 7 is inserted into the socket 802 of the expansion connector 8, the expansion connecting tube 7 is perpendicular to the tenon 801 on the expansion connector 8, and the tenon 801 and the expansion connecting tube 7 are located on opposite sides of the expansion connector 8.

[0052] As attached Figure 2 , 6 As shown in Figure 7, the connector 1 is provided with a closed sleeve portion 102, a notched sleeve portion 103 and a bottom hole portion 101, and the tenon groove 6, the closed sleeve portion 102 and the notched sleeve portion 103 are all arranged around the bottom hole portion 101.

[0053] Specifically, in this type of extended splicing box, the connector 1 is square column-shaped, with a bottom hole 101 located at the center of the square column connector 1. Two tenons 6, a closed sleeve 102, and a notched sleeve are respectively located on the four side walls of the connector 1. The closed sleeve 102, the notched sleeve 103, and the bottom hole 101 can all be used to insert the connecting pipe 2. The support rod 5 is used to insert into the bottom hole 101, the closed sleeve 102 is used to insert the extended connecting pipe 7 without the support plate 702, and the notched sleeve 103 is used to insert the extended connecting pipe 7 with the support plate 702.

[0054] Specifically, in this splicing box, in order to improve the stability of the closed sleeve part 102 and the notched sleeve part 103, a reinforcing rib 104 is provided between the notched sleeve part 103 and the connector 1, and a reinforcing rib 104 is provided between the closed sleeve part 102 and the connector 1.

[0055] Specifically, in this splicing box, both the closed sleeve part 102 and the notched sleeve part 103 are provided with an inner column 13. The inner column 13 is used to fit tightly against the inner wall of the connecting pipe 2 or the inner wall of the extended connecting pipe 7, thereby improving the insertion stability of the connecting pipe 2 and the extended connecting pipe 7.

[0056] As attached Figure 8 As shown, in this type of splicing box, the socket 802 of the expansion connector 8 is also provided with an inner post 13, which is used to fit tightly against the inner wall of the expansion connection tube 7.

[0057] As attached Figure 1 and5 As shown, it also includes an extension plate 4, which is disposed within the clamping opening 701.

[0058] Specifically, the expansion plate 4 is placed directly inside the clamping opening 701, and the expansion plate 4 is supported by the support piece 702 inside the clamping opening 701.

[0059] As attached Figure 4 As shown, it also includes a tie rod bracket 11, which is mounted on the box frame.

[0060] As attached Figure 4 As shown, it also includes a rotating wheel, which is rotatably mounted on the box frame.

[0061] As attached Figure 4 As shown, it also includes a bracket 10, which is disposed on the box frame.

[0062] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent modifications made based on the content of the present invention specification, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
