During operation, the leadscrew (14A or 14B) of one screw-type actuator (12A or 12B) is rotated while the leadscrew (14A or 14B) of the other screw-type actuator (12A or 12B) is locked.
The gate (1) can be adjusted vertically by a leadscrew (16) to set the weir level.
The bolt (40) includes a threaded shank (41).
The distal segment (120) includes a head portion (122) and a threaded shank portion (124).
An implant (20) comprising a specially adapted bone screw having a threaded shank portion (22) and a sleeve (42) which mates with and operates in cooperation with the threaded shank portion (22) is provided.
The threaded shank (2) is composed of a shank core (10) and an automatically thread-forming thread (12).
The invention relates to a countersunk head screw (1) comprising a thread shank (2) and a countersunk head (4) that has a conical surface (6) tapering in the direction of the threaded shank (2) with a countersinking angle (α).
Nuts attach the threaded rod to the tube.
The threaded rod (10) is furnished with a groove (14) which engages with a protrusion (54) to avoid its rotation of the threaded rod.
The stop is formed by manufacturing a threaded rod having an unthreaded cylindrical portion and one or more grooves (5) cut or manufactured longitudinally in the rod across both the threaded section and the unthreaded portion.
In the operating position, the first threaded part forms with the second threaded part an internal thread (26) interacting with the threaded rod.
A hinge may be attached to the extreme of the threaded rod.
One post (17) is provided with a threaded stud (18) extending axially from the bead, and the other post (21) is tapped within the bore of the bead (22) to receive the threaded stud.
The stud (46) also has an elongated portion extending from the partially squashed ball portion.
The stud (46) has a partially squashed ball portion (47) bonded to the chip contact pad (42).
A shank (12) has an upper shank portion (18) and a lower shank portion (20).
A coupling between the lead screw and the lead screw nut allows a helical movement of the lead screw.
A coupling between the lead screw and the lead screw nut allows a helical movement of the lead screw with respect to the lead screw nut at least in the axial direction.
The screw rod (25) is arranged in a cavity of the screw rod jacket (26), and a push rod (29) is provided between the screw rod (25) and the screw rod jacket (26).
The screw rod driving device (3) comprises a handwheel (31), a screw rod (32), a screw rod seat (33) and a fixing block (34).
The handwheel (31) is fixed at one end of the screw rod (32), the screw rod (32) is mounted on the screw rod seat (33), and the screw rod seat (33) is fixed on the fixing plate (13).
A ball screw (26) has a screw shaft (29), a nut (25) surrounding the screw shaft (29), and balls (30) engageable with the screw shaft (29) and the nut (25).
A lead screw (5), a lead screw nut and a drive member are aligned with an axis (4).
The lower shank portion (20) is threaded for penetration into the underlying structure.
The screw rod (1) passes through the gear base (3).
The screw rod has key ways (12).
A longitudinal threaded shaft (14) transverses the longitudinal hollow portion.
The drive mechanism comprises a lead screw (5) and a lead screw nut, which are aligned with an axis (4).
The rod receiver containing a receiver body coupled to a threaded shaft.
A mechanism for positioning the heads (68, 68') includes a lead screw (36) and a drive nut (38) which is rotatable relative to the lead screw (36).
