The invention relates to a large-volume leather bag type constant-pressure energy accumulator and application thereof. The large-volume leather bag type constant-pressure energy accumulator comprisesa shell and further comprises a leather bag, a variable area piston, a floating piston, a piston and a flange which are arranged in the shell. The floating piston sleeves a piston rod of the variablearea piston. The bottom end of the piston rod of the variable area piston is connected with the piston, and a through hole is formed in the center axes of the variable area piston and the piston, an inflation valve is connected between the through hole and the leather bag, the bottom of the through hole is connected with a cover plate, the piston is provided with a one-way valve I and a one-way valve II, and the flange is connected with the inner wall of the bottom of the shell. The novel large-volume leather bag type constant-pressure energy accumulator has the advantages that leakage is notlikely to happen, the service life is long, inertia is small, the response is sensitive, and the applicable volume range is wide; and the novel large-volume leather bag type constant-pressure energy accumulator can be widely applicable to various hydraulic systems.

The invention discloses a life jacket which comprises a life jacket body which is a clothes-shaped body with an integrated structure, wherein the body is an air bag body with an inner layer structure and an outer layer structure; an inflating device is arranged on the body and used as a self-service built-in inflating device; the whole body has a closed structure; the inflating device is communicated with a front part, a back, sleeves and trouser legs which form the body through inner hollow cavities of the body; and a zipper is arranged on the front part of the body, and is a waterproof zipper. Compared with the existing life jacket, the life jacket disclosed by the invention has the advantages that: 1, the life jacket is integrated, so that a human body can be protected from being contacted with water to the maximum extent, a phenomenon of heat loss is avoided, physical strength and body temperature consumption of people falling into the water is reduced, and a phenomenon that the people falling into the water is prevented from being frozen to death in the cold water is avoided; 2, by adopting the self-service built-in inflating device, the life jacket is relatively convenient and easy to wear, and a user can inflate the life jacket by own after wearing the life jacket; and 3, the whole structure is relatively simple, the cost is relatively low, and the life jacket is relatively convenient to use.

The invention provides an inflator pump which comprises an air pressure gauge with a gauge face and a gauge cover. A first illuminating lamp is arranged on the outer wall of the inflator pump. A circuit providing power for the first illuminating lamp is arranged in the inflator pump. When a tire needs inflating at night, an air cock of the inflator pump can be aligned with an air inlet of the tire easily through illumination of the first illuminating lamp, and the tire can be inflated, so that time can be saved. Moreover, the gauge face of the air pressure gauge is a transparent gauge face, namely, the gauge face is transparent. A second illuminating lamp is arranged on the side, far away from the gauger cover, of the gauge face. A circuit for providing power for the second illuminating lamp is further arranged in the inflator pump. When the tire needs inflating at night, the second illuminating lamp is turned on. Due to the fact that the gauger face is transparent, light rays of the second illuminating lamp can irradiate from the gauge face. Consequently, numerical reading of the air pressure gauge can be easily conducted through the illumination of the second illuminating lamp. The inflator pump can be used for inflating the tire at night easily.

The invention discloses a minitype rubber bag accumulator for a shock absorber. A cylinder barrel of a shock absorber compensation chamber is formed by connecting an inner cylinder barrel body and an outer cylinder barrel body into a whole through threads. A gas sealing screw plug is screwed tightly on an inflating sealing flange and arranged in a compensation cavity of the inner cylinder barrel body. The concave part of the bottom of a minitype rubber bag is radially fixed to a protrusion of the bottom end of the cylinder barrel of the shock absorber. Through a floating piston and a minitype rubber bag accumulator assembly installed under the flowing piston, complete isolation of a damping oil chamber and an inert gas chamber is achieved. Fold-type minitype rubber bag outer lugs are sleeved with fastening aluminum alloy flanges, the rubber bag and the fastening aluminum alloy flanges are connected through bolts and the inflating sealing flange, thus isolation of damping oil liquid and high-pressure gas is achieved completely, and oil-gas mixing is avoided. The defect of damping oil liquid flowing filling hysteresis is further overcome, and the idle stroke hidden danger of the shock absorber is avoided. The minitype rubber bag accumulator is different from a traditional rubber bag accumulator, the rubber bag and the damping oil liquid are isolated completely, aging is not liable to occur, the service life of the rubber bag is prolonged, the work responsivity is high through the fold-type appearance design, and the working load bearing ability and impact resistance are high.

The invention discloses an inflation method, which includes the following steps: opening the protective cover, rotating the locking part, aligning the crimping part of the locking part with the escape opening on the outer connecting flange of the protective cover, and pulling the protective cover along its axis Open and remove; install the gas cylinder, align the gas cylinder with the inflatable core for connection and fixation; buckle, buckle the protective cover to the buckle, so that the buckle part of the lock can pass through the avoidance port on the outer flange of the protective sleeve Stretch out, and then rotate the lock to make the buckle buckle the outer connecting flange; inflate, close the pressure relief valve, open the inflation valve to inflate; release pressure, when the value of the pressure gauge of the cylinder is observed to reach the predetermined value, close the inflation Valve, open the pressure relief valve to release the pressure; take the bottle, when the value of the pressure gauge of the gas cylinder is observed to be zero, it means that the residual pressure of the gas circuit has been released, at this time, open the protective cover and take out the gas cylinder.
