The utility model relates to the technical field of building construction, and disclose a kind of slope roof metal roof tile batten connecting piece and ridge beam's fixed structure, including the ridge beam of civil engineering structure and the slope roof of ridge beam connection setting, ridge beam top fixed ridge modeling, slope roof top is provided with roof tile, roof tile is fixedly connected with ridge modeling, roof tile includes keel, and keel is fixedly connected between ridge beam by connecting mechanism, connecting mechanism includes connecting piece and support piece, connecting piece can be adapted to sleeve on ridge beam, and connecting piece and ridge beam are fixedly connected between by fastener, and fastener includes tension bolt, connecting piece and ridge beam correspond to set through connecting hole, tension bolt is arranged in connecting hole, the outside of connecting piece is fixed support piece, and the end of keel towards ridge beam is supported on support piece and is fixedly connected with support piece, improve the stability and construction convenience of metal roof tile on slope roof installation.

The sectional type tensioning structure is characterized in that a plurality of pole frames are axially arranged and axially compressed through a positive end pressing plate and a negative end pressing plate, one or a plurality of middle frames are axially arranged among the pole frames at intervals, the middle frames radially extend to protrude out of the outer contours of the pole frames, and the outer contours of the middle frames extend out of the outer contours of the pole frames. The radial outer edges of the middle frame, the positive end pressing plate and the negative end pressing plate form spaced fixing parts, and every two adjacent fixing parts are fixed and tensioned through a tensioning mechanism. The sectional type connection mode can disperse pressure and pulling force borne by each small chamber pole frame, effectively prevents the pole plates and the gaskets from drooping, reduces risks of pole plate dislocation and sealing failure, and improves stability and reliability of the electrolytic cell.

The utility model provides a plug with temperature detection function, including insulating casing, be located in the plug pin support of insulating casing, be located on the plug pin support and the plug pin that stretches out insulating casing, with the wire and contact type temperature sensor of plug pin connection, still include heat conduction spare, heat conduction spare is located on the plug pin support and tightly wraps the fire line of wire, be equipped with the containing bin between plug pin support and heat conduction spare, temperature sensor is located in containing bin and is tightly wrapped by heat conduction spare. Compared with prior art, the utility model discloses a plug through the containing bin of fixed temperature sensor of plug pin support and heat conduction spare formation, need not to set other structures, fixed structure is simple, and fixed effect reliability is high.

This utility model discloses a fixing structure for an expansion tank in a heating boiler. The expansion tank has an elliptical columnar structure, with the length of the major axis of the ellipse parallel to the height of the heating boiler. A ring of protruding mounting reinforcing ribs is provided near the middle of the annular sidewall. Both sides of the expansion tank are equipped with tank fixing devices. Each fixing device has a concave arc-shaped structure matching the corresponding part of the expansion tank, extending downwards from the outermost ends of both sides of the expansion tank. On the facing inner surfaces, grooves are provided at the positions corresponding to the mounting reinforcing ribs. Each groove extends arc-shaped along the corresponding part of the mounting reinforcing rib. An expansion tank fixing plate is provided on the upper part of the expansion tank. The expansion tank fixing plate includes an expansion tank support extending downwards along the side of the expansion tank facing away from the back plate. This utility model simplifies the fixing structure of the expansion tank in a heating boiler, reducing material processing costs and assembly steps.

A heating pump comprises a pump shell, a pump cover covering the pump shell and a heating component arranged in the pump cover, a water passing cavity is formed between the pump shell and the pump cover, the heating pump further comprises a heat conduction installation base assembly, a temperature controller and a fuse protector, the heat conduction installation base assembly is fixed to the heating component, and the temperature controller and the fuse protector are fixed to the heat conduction installation base assembly. The heat conduction mounting base assembly and the fuse are in contact with the heating component, and the temperature controller is in contact with the heat conduction mounting base assembly. According to the heating pump, the heat conduction installation base assembly is arranged and fixed to the heating component, the temperature controller and the fuse are fixed to the heat conduction installation base assembly through the screws and the nuts, and compared with a traditional fixing structure, an upper connecting piece of the traditional fixing structure can be omitted; therefore, the fixing structure of the temperature controller and the fuse is simpler, the temperature controller and the fuse are easier to assemble, the assembling efficiency is improved, and the manufacturing cost is reduced.
