摘要： A connecting device of a retaining ring of a safety belt includes a main body, a bolt, and a locking member. The main body is used with the bolt to form an enclosure or not. The bolt passes through a bolt bore of the main body and has a first teeth portion and a stopper located in a first half part of the first teeth portion. The first teeth portion and the locking member are used to control the bolt to lock or to unlock. The locking member could move between a first position and a second position along an axial direction of the locking member and could rotate around a central axis of the locking member. When the bolt is at a closed position and the locking member is at the first position, a second teeth portion of the locking member is meshed with the first half part. When the bolt is at the closed position and the locking member is at the second position, the second teeth portion is meshed with the second half part.

摘要： A fall protection device includes a frame, a rolling member, a safety belt, a braking plate, a braking part, and a restoring spring. The frame has a first side plate. An outer side surface of the first side plate is provided with a blocking part. A rolling member is rotatably disposed on the frame. A safety belt is wound around the rolling member. A braking plate is engaged to the rolling member and has an inner side surface, which faces the outer side surface. The braking part is pivotally disposed on the braking plate and is located between the inner side surface and the outer side surface, whereby to ensure that the braking part at a braking position could be abutting against the blocking part.

摘要： A fall protection device including a first housing part, a second housing part, a rotation unit, a safety belt, a spiral spring for coiling the safety belt around the rotation unit and a brake unit for limiting rotation of the rotation unit is disclosed. The first and the second housing parts respectively include a first containing room and a second containing room. The first and the second housing parts conjugate with each other and constitute a housing. The brake unit is positioned in the first containing rooms, while part of the safety belt and the spiral spring are positioned in the second containing rooms. By separately positioning the brake unit and the safety belt in the first and the second rooms, the dust coiled together with the safety belt into the housing will not adhere to the brake unit and its effect on the brake unit's function is prevented.

摘要： An axial buffer device and a fall protection device including the axial buffer device are disclosed. The axial buffer device includes a buffer rod having a first friction surface; and a buffer member having a second friction surface which contacts the first friction surface. When any one of the buffer rod and the buffer member is pulled by a force which is greater than a default value to overcome a maximum friction between the buffer member and the buffer rod, the buffer member would slide on the buffer rod with friction to cushion the pulling force. The fall protection device includes a frame, a rotary member disposed in the frame and adapted to roll up a safety belt, and the axial buffer device. One of the buffer rod and the buffer member is connected to a hanging point and the other one is connected to the frame.

摘要： A safety catch connector, which is adapted to be connected to a sling and a harness, including a body, a catch member, a first locking member and a second locking member. The body is adapted to be connected to the harness. The catch member is pivotally connected to the body for pivoting relative to the body between an unlocked position and a locked position. The first locking member and the second locking member are disposed on the body. The first locking member is operable to move between a first position and a second position on the body. The second locking member is operable to move between a third position and a fourth position on the body. When the first locking member is at the first position and the second locking member is at the third position, the catch member is locked at the locked position.

摘要： A safety belt buckle, which includes a buckle member, a hook, a stop member, a latch member and a release button, wherein the latch member has a tongue plate which enters a chamber of the buckle member through a lateral opening of the buckle member, and pushes the stop member to a predetermined position; when the stop member stays at the predetermined position, the hook is restricted by the stop member, and stopped at another predetermined position to engage the tongue plate, which makes the latch member unable to separate from the buckle member. By pushing the release button connected to the stop member, the hook can pivot unrestrictedly, therefore the tongue plate is no longer engaged by the hook, and the latch member and the buckle member can separate from each other.

摘要： A carabiner includes a retaining frame, wherein each of two opposite sides of the retaining frame has a pivotally connecting portion and an inserting tube, respectively. The inserting tube has an inserted hole inside and is fitted around by a socket portion of a hook-shaped tube of the hook member. A wire rope passes through the hook-shaped tube. A bottom end of the wire rope is inserted into the inserted hole. A nose is engaged with a free end of the hook-shaped tube and a free end of the wire rope. A portion, where the socket portion, the inserting tube, and the wire rope are overlapped, is compressed to fix. The pivotally connecting portion is pivotally connected to a gate member. A top end of the gate member is detachably hooked to the nose. With such design, the weight of the carabiner could be reduced without worsening the safety.

摘要： An anchoring device includes a track bar, a restricting member, and a locking device, wherein the track bar has a receiving groove. The restricting member is put into the receiving groove through open ends of the receiving groove. A width between a section of walls of the receiving groove and a width of a portion of the restricting member is greater than a width of a mouth of the receiving groove. The locking device includes a main body wherein a locking portion is disposed on the main body and is manipulatable to move between a first position and a second position. The main body slidably fits around the track bar. When the locking portion in the second position, the main body could slide to fit a flange of a fixture. After that, returns the locking portion back to the first position to fix the main body on the track bar.

摘要： A fall arrest device includes a bracket, a rotating member rotatably mounted to the bracket, a safety belt wound around the rotating member, a brake wheel connected to the rotating member, a brake block pivotally connected to the brake wheel, and a restoring spring fitting around the second segment and having one end thereof terminating in a ring that has an inner diameter smaller than an outer diameter of the first segment. Another end of the restoring spring is connected to the brake block. The brake wheel has a fixed rod having a first segment and a second segment. An outer diameter of the first segment is greater than an outer diameter of the second segment. The restoring spring urges the brake block to be located in a restoring position. Thus, the restoring spring could be prevented from falling out of the fixing rod.
