The seat type axle-driven bicycle of the invention keeps the rear-wheel driven structure style, changes the chain-driven structure into axle-driven one and improves the drive efficiency. At the same time, the improved seat can be adjusted not only in the vertical direction but also in the anterior-posterior direction, so that a rider can comfortably rides on the seat against the seat back, thereby thoroughly preventing critical organs at the crotch of people from being hurt. Besides, the invention has the advantages of labor saving for driving and nimble, smooth and safe operation and is comfortable to ride and flexible to steer.

An emergency escape opening system for a bus door comprises a connecting rod mechanism and a soft connecting pulling device, wherein the connecting rod mechanism comprises a rocker, a connecting rod and a sliding cover, an air cylinder body is taken as a machine seat by the connecting rod mechanism and is symmetrically arranged at the tops of two sides of the air cylinder body axis, a connecting rod (or the rocker ) is taken as a driving member, and a pulling rope in the soft connecting pulling device is connected with the driving member in the connecting rod mechanism. When emergency occurs, a passenger pulls the pulling rope so that an exhaust valve is driven to open, the connecting rod mechanism is driven, and then an air cylinder piston is driven to open the door in sequence.

The invention relates to a device for completely moving a railway turnout. The device is used for thoroughly solving the problems of the conventional railway turnout replacing method that a turnout rail jack, a rail car and a rail crane are used to work together, the cost is high, the transportation resource is occupied during the running of the car, much blockade time is required for eliminating fault during the replacing process, large manpower and material resources are required and the construction process is unsafe. A slide rail is utilized to completely move a pre-paved turnout to a to-be-replacing place. A slide rail is paved between two adjacent turnout sleepers (preferably, two turnout sleepers with same length) within a certain length scope of the pre-paved turnout. The device is characterized by comprising at least 5-15 sets of moving units; two turnout replacing trolleys are arranged for each set of moving unit; the turnout replacing trolleys are respectively arranged on the slide rails at two ends of the two adjacent turnout sleepers (preferably, two turnout sleepers with same length) of the pre-paved turnout; and each of the turnout replacing trolleys is composed of a lifting device, a lateral moving pulley and a longitudinal adjusting pulley. The device provided by the invention is economical, safe, convenient and quick.
