The application relates to the technical field of house building sewage equipment installation, and discloses a sewage treatment equipment installation structure which comprises a sewage treatment equipment box and three equidistantly arranged exhaust inspection boxes fixed on the top of the sewage treatment equipment box for exhaust, the sewage treatment equipment box is placed in a foundation pit for underground installation, a concrete mortar foundation is laid in the foundation pit and used for placing and installing the sewage treatment equipment box, a guide mechanism for guiding the sewage treatment equipment box to be installed is arranged on the concrete mortar foundation; the guide mechanism comprises two groups of guide adjusting components and guide wheel components which are symmetrically placed on the two sides of the sewage treatment equipment box. The sewage treatment equipment installation structure can stably and accurately lower the sewage treatment equipment, workers do not need to repeatedly communicate with crane workers in the foundation pit, the operation difficulty of the crane workers is reduced, the risk of accidents of the workers is avoided, and the installation efficiency of the sewage treatment equipment is effectively improved.

The invention discloses a parachute-free air-drop bag, and belongs to the technical field of emergency rescue and air transportation materials, the basic material of the air-drop bag is an ultra-high molecular weight polyethylene composite material, the air-drop bag comprises a vertically placed bag body, a plurality of blast pockets are sewn on the upper portion of the outer wall of the bag body, and longitudinal braids and transverse shrouds which are arranged in a crossed mode are sewn on the outer portion of the bag body. A buffer air cushion is sewn below the bag body; the buffering air cushion is formed by combining a soft buffering cushion, a hard buffering cushion and a buffering cushion sleeve, a plurality of air inlet holes are evenly distributed in the bottom of the buffering cushion sleeve, a plurality of air outlet holes distributed circumferentially are transversely formed in the side face of the buffering cushion sleeve, and the air inlet holes and the air outlet holes are all communicated with the soft buffering cushion. The parachute-free air-drop bag provided by the invention is wear-resistant and anti-collision, not only can the accuracy of air-drop be ensured, but also air-drop materials can be effectively protected, and secondary ejection during landing collision is avoided.

The utility model discloses a kind of capping head, ring pull slide and its cap screwing machine, to solve the deficiency that current cap screwing machine is easy to cause press bending cover. The utility model includes material pushing rod and capping head body, capping head body includes capping neck, capping cylinder and capping horn, material pushing rod includes material pushing rod body and material pushing head, the bottom of capping cylinder is equipped with counterbore adapting material pushing head, capping neck and capping cylinder are equipped with inner hole adapting material pushing rod body, along the direction of capping neck to capping horn, the inner diameter of capping horn gradually increases, capping horn includes first guide section, step plastic section and second guide section, each place of first guide section and second guide section is continuously transition, and round corner is equipped between the two step surfaces of step shaping. Material pushing head can completely enter into counterbore, first guide section and second guide section provide more space and more guide to the inclined ring pull cover, drive the ring pull cover of lighter degree of deflection reset, reduce the probability of press bending cover condition.
