A seatbelt retractor assembly (10) has a seatbelt retractor (14) and an actuator (26) for locking and unlocking the seatbelt retractor (1). An inertial sensor mass (30, 32, 33) detects changes in vehicle speed. The mass (30, 32, 33) has a guide surface (34, 35, 36) for interacting with the actuator (26). The guide surface (34, 35, 36) moves between an unlocking position in which the actuator (26) unlocks the seatbelt retractor (14) and a locking position in which the actuator (26) locks the seatbelt retractor (14). The guide surface (30) has an inner profile portion (62) and at least an outer profile portion (64). The actuator (26) is in contact with the inner profile portion (62) in the unlocking position while moving into contact with the outer profile portion (64) as the actuator (26) moves towards the locking position. The inner profile portion (62) causes a different acceleration of the actuator (26) than the outer profile portion (64).

A cage having an automatic door is described. A front side of the cage is provided with a door panel. A top edge of the door panel is hingely attached to the cage. A bottom edge of the door panel is attached to the cage through a spring. A pedal is provided on a bottom surface of the cage. A front side of the pedal is hingely attached to the cage. The pedal is connected with a connecting rod. An upper end of the connecting rod extends upward and forward along a sidewall of the cage and is bent towards an exterior of the door panel. A spring supporting seat is fixed on the sidewall of the cage. Said spring supporting seat is connected with a spring. The connecting rod is fixedly provided with a spring contact point. Spring can move the connecting rod up toward the top of the cage and forward toward the front of the cage to lift up the pedal. A hook is fixedly provided on an outer surface of the door panel. An opening of the hook faces the top of the cage. When the door panel is in its fully open position, a bending portion of the upper end of the connecting rod locks into the hook. When the pedal is pressed down, the connecting rod is pulled downwardly and detached from the hook. The door panel moves down automatically to close the cage. In case of trigger mechanism failure, the door panel can be lifted by one hand, and quickly and automatically locks in position to restart, no other manual adjustment is needed.

The invention belongs to metal continuous casting equipment, relates to a slab continuous casting fan-shaped segment locating and locking device and an assembling method, in particular to slab continuous casting machine auxiliary equipment. The device comprises a first fan-shaped segment, a second fan-shaped segment and a bearing mechanism. The fan-shaped segments are formed by connecting line rollers and roller frames. The first fan-shaped segment is fixed to the second fan-shaped segment. The first fan-shaped segment is connected with a lower opening of a crystallizer. Roller frame hooks are hung on bearing frame hanging pins. The device is characterized in that rectangular deep grooves of 8-12 mm are formed in the two sides below the right portion of each bearing frame, and locating and locking mechanisms with adjustable locking hole grooves are fixed in the rectangular grooves by fixing bolts; and brackets below the roller frames fall down to be inserted in the locking hole grooves, and zero clearance is kept during locking. The device has the beneficial effects that the concept is novel, the structure is simple, compact and reasonable, and running is stable and reliable; after online mounting and arc jointing, fast locating and locking are carried out, mounting and demounting are convenient, time is saved, and the fan-shaped segment arc jointing precision is improved and stabilized; and the casting blank quality is effectively improved, the accidents of blank stagnation and steel leakage are reduced, and it is guaranteed that continuous casting production is carried out smoothly.

The invention discloses a mounting nut of a prestressed steel bar, which comprises a fixed-end mounting nut and a stretch-end mounting nut that are respectively provided with a threaded sleeve; the inside diameter of the threaded sleeve is slightly larger than the diameter of the prestressed steel bar; the middle part of the inner wall of the threaded sleeve is provided with a section of threads;the end surface of the tail part of the threaded sleeve is embedded with a magnet ring in a concentric way; the sleeve end of the threaded sleeve expands and forms a locating surface towards one sideof the tail part of a locating column; and the sleeve end of the fixed-end mounting nut is fixed with the locating column with a locating column end inwards to the thread section. The nut has simple and reliable structure, convenient manufacture and low cost, ensures the reliable installation of an anchor backing plate, simplifies the installation process of the anchor backing plate, reduces the tool kind and amount in the construction site and the labor intensity of the workers, quickens the construction progress, saves a great deal of working hours, and realizes the fast installation of theprestressed steel bar.
