the utility model discloses divide into the barrel with the stand and connect independent unit, the barrel adopts the combined material barrel, has alleviateed weight greatly, has strengthened acid and alkali corrosion resistance nature, the joint at both ends keeps the structural strength when metal material has guaranteed the erection joint.
As the improvement of the utility model, the periphery processing that connects has the hoop groove, and the structure is glued and is filled the hoop inslot. Because the external diameter that connects equals with the internal diameter of barrel basically, the inconvenient interpolation of structure glue during actual assembly, through design hoop groove and filling the structure glue at the hoop inslot, made things convenient for the interpolation of structure glue, when the barrel was packed into to the joint simultaneously, the distribution of structure glue through certain squeezing action was more abundant.
As the improvement of the utility model, the periphery that connects is equipped with the flange limit, the both ends of barrel are contradicted the flange limit is inboard. The flange edge is designed to facilitate the assembly of the emitter tube bundling device and the assembly and positioning between the joint and the tube body.
As the improvement of the utility model, the barrel and the joint connection section are processed with connecting holes, and connecting pins are arranged in the connecting holes. The design of the connecting hole and the connecting pin enhances the reliability of the connection between the cylinder and the joint.
As the improvement of the utility model, the connecting hole is processed into the bell mouth, the connecting pin adopts the taper pin. The conical hole is matched with the conical pin, so that the reliability of connection between the cylinder and the joint is further enhanced, and the connecting pin is more convenient to assemble.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
The composite upright column of the launch canister bundling device shown in fig. 1-4 comprises a cylinder body 1 and joints 2, wherein the cylinder body 1 is a carbon fiber composite cylinder body 1, the inner diameter of the composite cylinder body 1 is 69.1mm, the outer diameter of the composite cylinder body 1 is 100mm, the joints 2 are metal joints 2, the outer diameter of each joint 2 is equal to the inner diameter of the composite cylinder body 1, two joints 2 are arranged and inserted into the cylinder body 1 from two ends of the cylinder body 1 respectively, and the joints 2 are bonded with the cylinder body 1 through structural adhesive.
In this embodiment, through having 8 circumferential groove 2a in the processing of 2 peripheries on connecting, before assembling with barrel 1, pack into circumferential groove 2a with structural adhesive earlier, will connect 2 again and insert barrel 1. Because the external diameter that connects 2 equals with the internal diameter of barrel 1 basically, the inconvenient interpolation of structural adhesive during actual assembly, through design hoop groove 2a and filling structural adhesive in hoop groove 2a, make things convenient for the interpolation of structural adhesive, when connecting 2 simultaneously and packing into barrel 1, the structural adhesive that is through certain extrusion is more abundant to be distributed on the contact surface, connects more reliably.
The periphery that connects 2 is equipped with flange limit 2b, has evenly seted up mounting hole 2c on the flange limit 2b, and the both ends of barrel 1 are contradicted at flange limit 2b inboardly. The flange edge 2b is designed to facilitate assembly of the launch canister bundling device, meanwhile, assembly positioning between the joint 2 and the canister body 1 is facilitated, the end face of the canister body 1 can serve as a bonding face, and connection strength of the canister body 1 and the joint 2 is guaranteed.
