The invention discloses a forward or backward tilt adjusting device for the seat surface of an engineering truck seat. The forward or backward tilt adjusting device comprises a lead screw base, a lead screw nut base assembly, a lead screw nut, a lead screw, a locating nut and an angle regulator bottom plate. The lead screw base is a first U-shaped plate. Two opposite plates of the first U-shaped plate are provided with lead screw holes respectively. The lead screw base is fixed to the angle regulator bottom plate. The lead screw penetrates through the lead screw holes and is fixed to the lead screw base. The lead screw nut base assembly is formed by combining a second U-shaped plate and a first L-shaped plate. The bottom of the second U-shaped plate is connected with the bottom of the first L-shaped plate. Two opposite plates of the second U-shaped plate are provided with first bolt holes respectively. The first L-shaped plate is provided with a second bolt hole. The locating nut is fixed to the angle regulator bottom plate and penetrates through the second bolt hole. The lead screw nut base assembly rotates relative to the locating nut. The lead screw nut is arranged in the first bolt hole and connected with the lead screw in a matched mode. The forward or backward tilt adjusting device is simple and stable in structure, and can conveniently achieve regulation of the tilt angle of a backrest of the engineering truck seat.
Description
technical field [0001] The invention belongs to the field of engineering vehicle seats, and relates to a front and rear inclination adjusting device of an engineering vehicle seat seat surface. Background technique [0002] Engineering vehicles are the backbone of a construction project. Their appearance doubles the progress of construction projects and greatly reduces manpower. Watching the operation of construction vehicles, one can't help but be shocked by the power of machines and technology. They are used for engineering carrying, excavation, emergency repair, and even combat. Common engineering vehicles include: heavy transport vehicles, large cranes, excavators, bulldozers, road rollers, loading vehicles, electric emergency repair vehicles, engineering emergency vehicles, government special engineering vehicles, off-road engineering vehicles, electric welding engineering vehicles, armored engineering vehicles (combat engineering vehicles) ), oxidant sewage treatment...
