Description

Technical Field

[0001] The utility model relates to the field of outdoor camping supplies, in particular to an extended splicing box. Background Art

[0002] Patent publication CN211408060U discloses a mobile restaurant for outdoor camping, which is essentially an expandable box. However, the box used as a mobile restaurant is essentially just two flat plates installed on the top of the box through hinges (labeled as 2b and 2C in the document respectively). Therefore, when used as a dining table, the box with this structure cannot actually be expanded in any direction according to its own needs, and its adaptability when used outdoors is relatively poor. Utility Model Content

[0003] In view of the above problems, the utility model provides an extended splicing box.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An extended splicing box includes a plurality of connecting tubes, a plurality of connecting heads and a box plate. The connecting tubes are plugged together with the connecting heads, and the connecting rods are matched with the connecting heads to form a hollow hexahedral box frame. The box plate is arranged on the box frame, and the connecting heads are located at the top corners of the box frame. It also includes an extended joint, a transition joint and an extended connecting pipe. The connecting head is provided with a mortise and tenon, the transition joint is provided with a mortise and tenon, and the extended joint is provided with a tenon. The tenon is used to be plugged with the mortise and tenon, and the transition joint is used to connect the extended joint. The two ends of the extended connecting pipe are respectively matched with the extended joint or the connecting head, and the extended connecting pipe encloses a plurality of clamping openings.

[0006] In this extended splicing box, firstly, a box frame is spliced ​​by connecting heads and connecting pipes, and then the box panels are installed on the box frame by means of snaps, so that a box is spliced ​​by connecting pipes, connecting heads and box panels, and the box can be opened and closed by disassembling the box panels on the box.

[0007] Similarly, in this type of extended splicing box, since the tongue and groove are set on the connecting head, and the connecting head is located at the top corner of the box frame (that is, equivalent to the connecting head being located at the top corner of the box frame), the four peripheral edges at the top corner of the box frame can be connected through the extended joint, which means that the four edges of the box can be connected with the extended connecting pipe as needed, so as to form a clamping opening by using the extended connecting pipe, and finally form a clamping opening at any direction of the box periphery as needed, and the clamping opening can be placed in different devices as needed, such as a stove as shown in CN307953838S, or a shelf as shown in CN308099229S. Specifically, in this type of extended splicing box, the clamping opening enclosed by the extended connecting pipe is a rectangular clamping opening.

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

[0009] Specifically in this type of expansion splicing box, the connecting pipe and the expansion connecting pipe are both hollow aluminum alloy pipes, which are light and have good rigidity.

[0010] Specifically in this extended splicing box, the mortise and tenon are square mortise and tenon are square mortise and tenon, and the square mortise and tenon are plugged together to have good stability.

[0011] Specifically in this extended splicing box, the transition joint is in the shape of a square column, and four mortises are arranged on the transition joint, and the four mortises are respectively located on the four side walls of the transition joint, so the transition joint can be connected to four extended joints at most. When the four extended joints are connected to the transition joint, the four extended joints are in a cross-shaped distribution state.

[0012] Optionally, a supporting sheet is further included, wherein the supporting sheet is arranged on the extended connecting tube and is located in the clamping opening.

[0013] The specific function of the supporting sheet is to support the instrument placed in the clamping mouth, thereby ensuring that the instrument in the clamping mouth has high stability and load-bearing performance.

[0014] Optionally, the support rod is plugged into and matched with the connector or transition joint, and the support rod is perpendicular to the extended connecting pipe.

[0015] The specific function of the support rod is to contact the ground to play a supporting role. When the support rod is plugged into the transition joint, the four tongues and grooves on the transition joint are distributed around the support rod.

[0016] Optionally, the extension joint is provided with a socket, and the extension connecting pipe is plugged into the socket.

[0017] The socket on the specific expansion joint is used to plug the expansion connection pipe. When the expansion connection pipe is plugged into the socket of the expansion joint, the expansion connection pipe is perpendicular to the tenon on the expansion joint, and the tenon and the expansion connection pipe are respectively located on both sides of the expansion joint.

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

[0019] Specifically, in this type of expansion splicing box, the connector is in the shape of a square column, the bottom hole portion is opened at the center of the square column connector, and the two tongues and grooves and the closed sleeve portion and the notched sleeve portion are respectively arranged on the four side walls of the connector. The closed sleeve portion, the notched sleeve portion and the bottom hole portion can all be used for plugging in the connecting pipe. The support rod is used for plugging and matching with the bottom hole portion, the closed sleeve portion is used for plugging in the expansion connecting pipe without a supporting sheet, and the notched sleeve portion is used for plugging in the expansion connecting pipe with a supporting sheet.

[0020] Specifically, in the present splicing box, in order to improve the stability of the closed sleeve part and the notched sleeve part, a reinforcing rib is provided between the notched sleeve part and the connecting head, and a reinforcing rib is provided between the closed sleeve part and the connecting head.

[0021] Specifically in the present splicing box, internal columns are provided in both the closed sleeve portion and the notched sleeve portion, and the internal columns are used to close to the inner wall of the connecting pipe or the inner wall of the extended connecting pipe, thereby improving the plugging stability of the connecting pipe and the extended connecting pipe.

[0022] Specifically in this type of splicing box, an internal column is also provided inside the jack of the expansion joint, and the internal column in the jack is used to be close to the inner wall of the expansion connection pipe.

[0023] Optionally, an expansion plate is also included, and the expansion plate is arranged in the clamping opening.

[0024] The specific expansion board is directly placed in the clamping mouth, and the expansion board is supported by the supporting sheet in the clamping mouth.

[0025] Optionally, a pull rod frame is also included, and the pull rod frame is arranged on the box frame.

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

[0027] Optionally, a bracket is further included, and the bracket is arranged on the box frame.

[0028] The beneficial effect of the utility model is that the four sides of the box can be connected with the extended connecting pipe as needed, so as to form a clamping opening by using the extended connecting pipe, and finally the clamping opening can be formed at any direction of the box periphery as needed.
