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).

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 fast positioning bolt locking device, which comprises a flange seat provided with an internal thread inside, a pressing nut provided with an external thread on the outside, a positioning pin embedded in the pressing nut, and a fixing pin for fixing the positioning pin. Pin seat, the middle part of the fixed pin seat is provided with a fixing hole, the end is provided with a flange; The flange plate of the pressing nut matches the flange plate at the end of the fixed pin seat, and the other end of the pressing nut placed in the flange seat is provided with a tooth cover; the middle part of the positioning pin is provided with a tooth plate matching the tooth cover. The invention makes up the gap between the tooling equipment and the fixed guide rail platform through the staged engagement and separation of the tooth cover and the tooth plate, and generates a great locking force, which can effectively solve the disadvantages of the traditional positioning method, and achieve fast and convenient locking. Tight positioning action; to avoid bending damage caused by the bolt, resulting in positioning failure, suitable for wide application.

The invention discloses a device for cutting an insulation support for a transformer body, comprising a workbench body. The workbench body comprises a workbench surface, four rectangular tubes which are arranged under the workbench surface to support the workbench surface, three cantilevers which are fixed on the workbench body and bulge out of the workbench surface, two guide rails which are arranged on the cantilevers in parallel and four moving guide plates which can move and be fixed by passing through the two guide rails.
