The utility model relates to a kind of ejection force reinforcing structure based on small elastic block, belongs to injection mould technical field, including injection mould, the injection mould is equipped with injection product, the injection product side lower end is equipped with ejection elastic block subassembly with injection mould interval.The ejection elastic block subassembly includes elastic block, the elastic block is equipped with the isohypse screw extending out the lower end of elastic block, the isohypse screw and the elastic block are equipped with the boss with isohypse screw hole type screw thread sleeve joint, the lower part of the elastic block and isohypse screw are equipped with the spring with isohypse screw sleeve joint.It has the characteristics of simple structure, good effect and high running stability.Through ejection elastic block subassembly, more powerful, more stable ejection force is provided in limited space, the powerful, stable, accurate ejection to difficult demoulding product is realized, while ensuring the accuracy of ejection action and the long life of mould.

The utility model discloses an air cooling fuel cell system integrated structure belongs to fuel cell technical field. The integrated structure is to set up fuel cell stack and its auxiliary components on the air deflector cover, and the side plate of air deflector cover and the cathode bottom plate, anode bottom plate of electric pile are connected to form the side surrounding casing structure of fuel cell stack, and the opposite side of fuel cell stack and fan is without side plate and opens to the environment, the fan in air management subassembly provides fresh air to the cooling and cathode flow channel on the polar plate in fuel cell stack, in hydrogen circulation subassembly, hydrogen passes control valve and enters hydrogen into the stack mouth on the cathode bottom plate, supplies to the anode manifold entrance of fuel cell stack through hydrogen flow channel in the cathode bottom plate, and the hydrogen that is not consumed is led out again by hydrogen out of the stack mouth on the cathode bottom plate and enters hydrogen circulation pipeline, and it is controlled by circulating pump to return to hydrogen into the stack mouth on the cathode bottom plate again. The utility model optimizes and reduces the overall size of fuel cell, guarantees the heat dissipation performance and improves the space utilization of fuel cell.

This utility model discloses a deck vertical lifting structure for a remote-controlled lawnmower, including a body, a deck suspension plate, an electric push rod, a transmission assembly, and a reset assembly. The body is a frame structure with fixed plates fixedly connected to the upper part of both sides of the rear. The electric push rod is fixedly connected to the front end of the fixed plates. The output end of the electric push rod is fixedly connected to the transmission assembly below via a U-shaped seat. The lower part of the transmission assembly is fixedly connected to the edge of the deck suspension plate. The middle part of the reset assembly is fixedly connected to the inner side of the body of the machine, and the bottom part is fixedly connected to the upper surface of the deck suspension plate. The electric push rod converts the horizontal driving force into a vertical force through the transmission assembly and transmits it to the deck suspension plate, realizing the lowering or raising of the deck suspension plate. The reset assembly enables the deck suspension plate to quickly reset when it needs to be raised after lowering. This application has the following advantages: improved mowing efficiency, improved mowing quality, enhanced terrain adaptability, reduced operating difficulty, and reduced structural space.
