  • Patent number: 11952246
    Abstract: Disclosed is a brake winch with reverse release and self-locking functions. The brake winch has a housing with first and second side walls, an accommodating space, and an auxiliary bracket part. A rotating disk is screwed in the accommodating space. A main shaft is screwed on one side of the rotating disk in an interlocking manner. A screw adapter is screwed on the second side wall, and includes an inner connection end that is assembled with the main shaft, and its external end has a threaded groove. The axial displacement of a driving screw, which is screwed on the auxiliary bracket, is matched with the difference of forward and reverse rotation to form a screwing transmission or release mode between the stud section and the thread groove. A friction driving mechanism must prompt the drive screw, the clamping plate and the screw adapter to be in a tightly synchronized state.

  • Publication number: 20140166800
    Abstract: A fastening strap unit includes a frame with a mandrel and a strap connected thereto. The strap is wrapped to the mandrel, and the first end of the strap is fixed to the mandrel and a hook is connected to the second end of the strap. A shaft extends from the frame and a motor drives the shaft which drives the mandrel. A first sensing chip is connected to the second end of the strap and a second sensing chip is connected to the first end of the strap. A sensor is connected to the frame so as to detect the first sensing chip or the second sensing chip when the strap is retracted or released to its final position, and the motor is stopped.

  • Patent number: 8672298
    Abstract: A jack includes an outer tube, an inner tube and a lifting device. The outer tube has a positioning member and a driving rod connected thereto. The positioning member is positioned by an object and the driving rod is driven by a crank. The inner tube is located in the outer tube and the lifting device is located on the top of the inner tube so as to lift the outer tube. The positioning member is located on the top of the outer tube and the driving rod is located below the positioning member. The positioning member is positioned by a pivotal device which pivots the positioning member to a desired angle and positions the positioning member.

  • Publication number: 20130082225
    Abstract: A capstan mechanism has one base, two location holes, one rotation axis, one driven gear set, one combination driving gear set and one rotation handle. Location holes on the base are needed to be made due to the combined style of the combination driving gear set and the rotation axis, and the hole diameter shall be big enough to let the rotation hole go through it. Thus the concentricity among the parts of the capstan mechanism is realized and the production cost is saved.
