This utility model relates to the field of pipe support technology and discloses an adjustable support hanger for pump room pipe installation. It includes a support base with connecting arms on both sides. The upper side of the support base has an upward-facing cavity. A threaded rod is threadedly connected to the lower side of the support base. A lifting rod is fixedly connected to the upper end of the threaded rod. A conical block is rotatably connected to the lower outer wall of the lifting rod. Clamping plates are provided on both sides of the conical block. The opposing sides of the two clamping plates and the upper side of the lifting rod are used to fit against the outer wall of the pipe. This utility model, through the connecting arms, support base, threaded rod, conical block, lifting rod, clamping plates, and cavity, achieves the function of fixing pipes of different sizes. This solves the problem of needing to purchase hangers of corresponding sizes when installing pipes of different diameters, resulting in a large variety of spare parts and increased procurement costs and inventory pressure.

The utility model relates to the technical field of automobile seat, concretely is a kind of pneumatic control shock absorbing seat, including chassis, seat and pneumatic shock absorbing component;Chassis includes upper frame and lower frame, and shear frame is arranged between upper frame and lower frame, and shear frame is symmetrically arranged between the both sides of upper frame and lower frame in two groups.The utility model is provided with the setting of chassis, seat and pneumatic component, when the seat structure in the cab is vibrated by the driving process of automobile, air bag can make seat repeatedly up and down movement in certain stroke range by repeated inflation and deflation, gradually offset the vibration effect directly conducted to seat in the process of continuous movement, so that the shock absorbing seat structure realizes shock absorption in effective stroke, thereby improve the comfort of driver, and the structure can realize the function of shock absorption for a long time, compared with traditional spring shock absorbing structure has higher service life.

The application provides a damping device and a wheelchair. The damping device comprises a support, a first limiting rod arranged on the support, a driving device fixedly connected with the support, an output end of the driving device connected with a wheel, the driving device being used for driving the wheel to rotate relative to the support, a swing arm fixed on the driving device, one end of the swing arm being rotatably connected with the support, the other end of the swing arm being provided with a connecting portion, an elastic member, the inside of the elastic member being hollow, one end of the elastic member being connected with the connecting portion, one end of the first limiting rod extending into the elastic member from the other end of the elastic member, the other end of the elastic member being abutted against or fixedly connected with the support, and the elastic member being elongated or contracted along the extension direction of the first limiting rod when the swing arm rotates. The application can improve the safety of the damping device.
