The utility model relates to aviation equipment technical field, concretely relates to a kind of helicopter satellite communication equipment mounting bracket: including pod assembly, cabinet assembly and airborne antenna assembly, airborne antenna assembly includes airborne antenna body, antenna support and antenna mounting plate, since antenna support borrows the bolt embedded hole position of the cable drop support of helicopter and is fixed at the top platform position of fuselage left side, airborne antenna body is installed in the above of antenna support by antenna mounting plate, and pod borrows the platen nut of fuselage radar cover bottom and is fixed, cabinet assembly is installed on the front seat guide rail of helicopter simultaneously, all connecting points are fixed using the bolt hole or mounting hole of helicopter using this technical scheme, need not additional trepanning or refitting, under the premise of guaranteeing structural strength, make satellite communication equipment installation efficiency improve, and fuselage is not any permanent change after dismantling, will not cause the influence to the overall structural strength of helicopter.

The utility model relates to aviation equipment technical field, concretely relates to a support for adding the support for adding the security communication equipment to the helicopter: including airborne antenna subassembly, pod subassembly and rack subassembly, airborne antenna subassembly utilizes the existing structure of fuselage, and the fixed point position is used to the line cutter support, foot rest support, door frame support and front block support, and the installation frame is directly connected with the original hole position of helicopter through bolt, does not need the additional trepanning or structural modification, and the fuselage integrity is completely reserved, the pod subassembly is inlaid with the original landing gear foot rest structure through the hoop, and the rack subassembly is then multiplex seat connecting piece mounting point, all connecting points adopt the bolt hole or hinge structure of helicopter in the prior art, do not need the additional trepanning or modification, under the premise of guaranteeing the structural strength, make the security communication equipment installation efficiency improve, and the fuselage has no any permanent change after dismantling, and the overall structural strength of helicopter will not be influenced.

The utility model relates to the technical field of anti-seismic supports, in particular to a profile steel mounting structure for an anti-seismic support, which specifically comprises a profile steel body, a connecting base and a bolt assembly, the profile steel body comprises a first web and a first flange, a plurality of first pentagram holes are formed in the first flange along the length direction, and the bolt assembly comprises bolts and nuts. The bolt comprises a screw part and a pentagram part, the connecting base comprises a U-shaped connecting piece, a pentagram combination hole is formed in the U-shaped connecting piece, and at least two clamping structures capable of being in sliding clamping fit with the pentagram part are formed in the pentagram combination hole. In the installation process, according to the actual installation error, the pentagram part of the bolt can select the clamping structure at the proper position in the pentagram combination hole to be in sliding clamping connection with the first pentagram hole, fine adjustment of the profile steel installation position is achieved, the connection problem caused by the installation error is effectively solved, additional drilling is not needed, the construction cost is reduced, the construction time is shortened, and the construction efficiency is improved. And meanwhile, the structural strength of the profile steel is not influenced.

The utility model discloses a kind of bag folding equipment, including bag folding assembly and limiting component, bag folding assembly has bag folding space, and including at least one bag folding component in the first direction located bag folding space side, limiting component includes limiting component in the second direction located both sides of bag folding space, in the second direction to the packaging bag in bag folding space is limited, prevent packaging bag when folding along first direction, second direction deviation or shift occurs, ensure that packaging bag under the action of bag folding component always along first direction neat folding, the structural strength of packaging bag after folding will not be greatly influenced, and through the bag folding posture of each packaging bag folded by this bag folding equipment is basically consistent, multiple packaging bags are stacked and stored when can be closely fitted, flat alignment, will not appear when stacking high and low staggered, skew deviation etc. Problem, greatly improve the utilization of storage space.
