The utility model relates to the technical field of reciprocating screw rod, concretely disclose a novel composite pitch reciprocating screw rod, including reciprocating screw rod main part, both sides of reciprocating screw rod main part surface all are equipped with damping assembly, the damping assembly includes fixed ring, and the inner chamber of fixed ring is connected with reciprocating screw rod main part fixedly, the inside of fixed ring is provided with damper at equal distance, the inside of damper is equipped with damping ring, the surface of damper is equipped with damping spring, and the both ends of damping spring are connected with the junction of fixed ring and damping ring and are all fixedly connected through the welding form. The utility model when needing to play the damping function to crescent guide block, first when the crescent guide block moves to the turning point of reciprocating screw rod main part, the crescent guide block will contact damping ring, through the impact force that the crescent guide block moved will be transmitted to damper and damping spring through damping ring, and the impact force that can be produced is reduced through damper and damping spring.

The invention relates to a protection device, in particular to a protection device for a turning gear. The invention aims to solve the problem that an operating element on the turning gear is damaged, corroded or loosened after being used for a long time and then is lost. The barrel-shaped protective cover comprises a fixed cover shell and a movable cover shell, the movable cover shell is hinged to the fixed cover shell through an opening and closing unit, and the axis of the opening and closing unit is parallel to the axis of the barrel-shaped protective cover. The open end of the fixed housing is fixedly connected with a flange plate, and the flange plate is connected with a shell of the turning gear through bolts. The device is simple in structure and convenient to operate, operation elements on the turning machine can be protected, and the risk that the operation elements are damaged, corroded, lost or mistakenly touched after being used for a long time is avoided; and moreover, the device is convenient to install and high in universality, the device can adapt to mechanical equipment of different sizes by changing the structural size, the function of protecting exposed parts on the mechanical equipment is achieved, and the safety of the mechanical equipment is improved. The invention belongs to the technical field of mechanical equipment protection devices.

The utility model relates to the technical field of vertical parking lots, and discloses a vertical multi-layer parking lot anti-falling supporting device which comprises a bearing plate, the two sides of the top of the bearing plate are each provided with a pair of first threaded holes, the two sides of the top of the bearing plate are each provided with a side plate, and bottom plates are fixedly arranged at the bottoms of the opposite sides of the two side plates. Fixing plates are fixedly arranged at the ends, close to the bottom plate, of the two side plates. According to the side plate, the gap between the fixing plate and the bottom plate is clamped into the bearing plate, then the fixing bolts penetrate through the fixing plate to be connected with the first threaded holes, and therefore fixing is achieved, the side plate can be conveniently and rapidly installed, and the side plate can protect and support the side face of a vehicle when the parking space swings due to too fast rising; and the situation that the vehicle falls can be avoided, and the protection capacity for the vehicle is improved.
