The utility model provides a cross-flow fan with composite spline curve blades, which relates to the technical field of cross-flow fans and comprises a first connecting plate and a motor output shaft, and a connecting shaft is fixedly mounted on one side of the first connecting plate. By rotating the rotating block, matching with the threaded connection of the bidirectional lead screw and the sliding plate and the sliding design of the sliding plate and the sliding groove, maintenance personnel can conveniently control the clamping ring to move, more labor is saved in mounting and dismounting, meanwhile, through the accurate matching of the limiting insertion column and the limiting hole and the stable clamping of the motor output shaft by the clamping ring, the maintenance efficiency is improved, and the maintenance cost is reduced. Compared with the prior art, firm connection is guaranteed, stable operation of the cross-flow fan blade is ensured, the fault risk is reduced, in addition, the limiting insertion column can be easily pulled out, unlocked and taken down by reversely rotating the rotating block, efficient and convenient disassembly is achieved, the time and energy of maintenance personnel during equipment maintenance, cleaning or component replacement are greatly saved, and the maintenance cost is reduced.

The utility model relates to the technical field of reducing joint, and disclose a kind of anti-explosion reducing joint of convenient connection, pipe;Mounting head, the pipe is arranged in mounting head side wall;Fixed cover, the fixed cover fixed sleeve mounting head outer wall;Movable cover, the movable cover rotation is connected in fixed cover outer wall;Limiting component, setting in mounting head outside, the pipe is fixed;Through the cooperation of conical block and conical groove realizes quick positioning, and then using movable cover, internal thread, external thread and the like structure, only need to rotate movable cover can complete the fixation of pipe, compared with traditional connection mode, greatly simplify the operation step, shorten construction time, reduce manpower cost, improve pipeline connection efficiency;Rubber ring forms sealing structure between pipe and movable cover, can effectively prevent flammable and explosive medium leakage;At the same time, after the cooperation and fixation of triangular clamping block and triangular clamping slot, the sealing property of junction is further enhanced.

The utility model discloses a ventilation type toilet tent which comprises a main tent body, a front gable wall door arranged on the front surface of the main tent body and a ventilation window arranged at a ventilation opening. The ventilating window further comprises a plurality of connecting assemblies arranged between the metal net frame and the fixed window frame. According to the toilet tent, the fixed window frames are designed at the ventilation openings in the two sides of the toilet tent, the sliding clamping pieces and the rotary rapid limiting structures are innovatively adopted between the window frames and the metal net frame, the existing technical problems are effectively solved, and through the design, the installation stability of the metal net frame at the ventilation openings is guaranteed; the problem that tarpaulin is damaged due to a traditional screw fixing mode is avoided, the disassembly and assembly process of the metal net frame is greatly simplified, cleaning and maintenance work is more convenient and efficient, more importantly, even though disassembly and assembly are conducted many times, connection between the metal net frame and the window frame is still stable and reliable, no damage is caused to the tent tarpaulin, and the service life of the tent is prolonged. Therefore, long-term stable use of the toilet tent is ensured.

The utility model provides a construction pipeline supporting and protecting device for gas construction management, and relates to the technical field of pipeline construction, the construction pipeline supporting and protecting device for gas construction management comprises a sliding base, a sliding part, a fixed plate, a rectangular plate and a supporting plate, the long sides of the sliding base are arranged in parallel, and a sliding groove for sliding is formed in the sliding base; and the limiting plate is rotationally connected into the rectangular groove, forms a complete plate shape with the fixing plate, and limits rolling of the pipeline when rotating to be attached to the pipeline. According to the pipeline connecting device, the limiting piece is released in the rotating process through the arranged inclined plate, the inclined plate can contract inwards in the moving process under the action of the limiting piece, the effect that the end of the sewing part is contracted and connected into the other pipeline in the butt joint process is achieved, and the pipeline connecting effect is easier and more efficient.
