The utility model relates to an inflatable sports knee pad convenient to adjust, which comprises an elastic sleeve, elastic support strips arranged on both sides of the elastic sleeve, a patella air bag arranged on the front side of the elastic sleeve, upper and lower branch air bags arranged above and below the patella air bag, and a binding assembly; an inflation port is arranged above the patella oval air bag; air-permeable assemblies are arranged above and below the popliteal fossa; the patella air bag is used to provide vertical impact protection in the patella area; the branch air bags arranged in a longitudinal and oblique manner in the collateral ligament area prevent lateral sprains; the elastic support strips on both sides of the elastic sleeve can reduce the impact force and pressure of falling; the mesh air-permeable knitted fabric above and below the popliteal fossa improves the moisture absorption and air permeability of the area, thereby effectively inhibiting the accumulation of sweat and providing comfortable air permeability; the left and right elastic bands are bonded to fix the elastic sleeve, prevent the elastic sleeve from moving upward, the lower band is bonded to prevent the elastic sleeve from moving downward, disperse the pressure, strengthen the protection efficiency, and the upper band and the lower band can keep the position of the knee pad stable.

The invention provides a rotorcraft emergency floating device and method.The rotorcraft emergency floating device comprises a buoy assembly and an inflation assembly, and the buoy assembly comprises a right front buoy assembly, a left front buoy assembly and a rear buoy assembly and is used for providing buoyancy and floating stability for a rotorcraft; the inflation assembly comprises a cylinder valve assembly and a pipeline assembly, is used for inflating the buoy assembly and has a manual / dampening automatic starting function; a right front buoy assembly and a left front buoy assembly are symmetrically arranged on the left and right sides of the front machine body, and are cylindrical in packaging shape; the right front buoy assembly and the left front buoy assembly are in a capsule shape when being inflated and unfolded. The rear buoy assembly is of a flat box body structure in a packaging state and has a good aerodynamic configuration; the rear buoy assembly is of a three-buoy structure connected side by side in the inflated unfolding state.

The embodiment of the present application relates to a kind of air bag, pneumatic comfort system and seat, air bag includes massage part, support part and air pipe;Massage part is supported in support part;The middle part of support part has hollow area;Support part is provided with air cavity, air cavity surrounds hollow area, air pipe is connected to support part, and air pipe communicates air cavity.By the air bag, since the middle part of support part is provided with hollow area, compared with the case where hollow area is not provided in prior art, the air cavity capacity of support part is smaller, the required inflation amount of the present application is also reduced when achieving the same top pressure stroke, in the inflation process, air source can be effectively saved and inflation speed is accelerated.In addition, the external dimension of support part is not reduced, so the air bag provided by the embodiment of the present application can still guarantee good massage and support effect.In other words, under the premise of realizing the same massage and support effect, the air bag of the embodiment of the present application not only reduces air source consumption, but also has faster inflation and deflation speed.

A multipurpose inflation pump is provided. The multipurpose inflation pump includes a housing (1) provided with a device cavity (2) and a storage cavity (3) which is configured to place an accessory. The device cavity (2) is provided with a first inflation unit and a second inflation unit, and an inflation pressure of the first inflation unit is lower than an inflation pressure of the second inflation unit. The multipurpose inflation pump can not only rapidly inflate and deflate an inflatable bed, an inflatable boat, etc., but also provide higher inflation pressure to inflate an automobile tire, thus combining multiple uses in a single machine and helping consumers save cost.
