Multifunctional hub

Abstract

A multifunctional hub according to the present invention includes a box body, and the box body is provided with a sliding cavity with an upward opening therein, and an annular slider is slidably slid in the sliding cavity. The multifunctional hub of the present invention has simple and clear operation, sensitive response, saving time and labor; at the same time, the device of the present invention is rich in functions, fixed and reliable, and highly practical.

1 . A multifunctional hub according to the present invention includes a box body, which is characterized in that the box body is provided with a sliding cavity with an upward opening therein, and an annular slider is slidably slid in the sliding cavity. A fixed block is fixedly provided, a grip is fixed on the outer end surface of the fixed block, locking teeth are fixed on the bottom surface of the fixed block, and a ring-shaped end face gear meshing with the locking teeth is fixed on the top surface of the box body. An inner ring gear is provided on the inner side of the annular slider, a first cavity is provided in the bottom wall of the sliding cavity, and a spline sleeve is arranged between the first cavity and the sliding cavity to rotate, and the spline sleeve A spline shaft extending up and down is provided inside, a gear meshing with the ring gear is fixed at the top of the spline shaft, and a first surface is connected between the bottom surface of the annular slider and the top surface of the spline sleeve. A spring, a first disc is fixedly provided at the bottom end of the spline shaft, and a first groove and a first groove with a downward opening are provided in the first disc; Ratchet teeth, a second cavity is provided in the bottom wall of the first cavity, and the second cavity and the first cavity A first chute is communicated between the cavities, and a slide bar extending up and down is slidably arranged in the first chute. A second disk is fixed at the top of the slide bar, and the top wall of the second disk is rotatably provided. There is a rotating shaft. A pawl that is engaged with the internal ratchet teeth is fixed on the rotating shaft. A second spring is connected between the pawl and the top surface of the second disc. The bottom end of the sliding rod is fixedly arranged. There is a third disc, a third spring is connected between the bottom surface of the third disc and the bottom wall of the second cavity, and a hydraulic cavity is arranged in the bottom wall of the second cavity, and the hydraulic cavity and the A second chute is communicated between the second cavities, a sealing ring is fixed outside the second chute, a first ejector rod is slidably disposed in the second chute, and a sliding device is disposed in the hydraulic cavity. There is a magnet block fixedly connected to the first jack, and a fourth spring is connected between the bottom surface of the magnet block and the bottom wall of the hydraulic chamber; therefore, the rotation of the ring gear drives the gear to rotate. The gear drives the first disc to rotate, while the magnet block drives the pawl to mesh with the inner ratchet teeth. 
     
     
         2 . The multifunctional hub according to  claim 1 , characterized in that: a third sliding groove with an upward opening is symmetrically provided in the bottom wall of the sliding cavity, and a second ejector rod is slidably provided in the third sliding groove. A hydraulic pipeline is provided between the third chute and the hydraulic chamber. A winding groove is fixed on the outer surface of the first disc. An end wall of the rear side of the first cavity is provided with an opening backward. A cable entry slot is provided in the rear end wall of the first disc, and a card slot is opened downward in the front end wall. A second groove is connected to the front side of the card slot, and a second slot is provided in the second slot. A card spring protruding into the card wire groove, and a fifth spring is connected between the card plate and the upper and lower end walls of the second groove; therefore, the card wire groove and the card plate cooperate to fasten the wire. The winding groove rotates and winds the wire. 
     
     
         3 . The multifunctional hub according to  claim 1 , characterized in that: a ring magnet is fixed on the bottom surface of the box body, a magnet base can be adsorbed on the bottom end of the ring magnet, and the magnet base is in phase with the magnet block A rubber strip is fixed at the bottom end of the magnet base; therefore, the ring magnet and the magnet base are fixed to fix the box body, and at the same time, the magnet base drives the magnet block to slide upward.
