Abstract: A ball screw device includes a ball nut having a bore for receiving a screw shaft, and having a number of longitudinal channels and compartments for forming a zigzag shaped fluid flowing passage in the ball nut, a number of deflecting members engaged with the compartments of the ball nut and each having a recess for communicating adjacent channels with each other, the outer peripheral surfaces of the deflecting members are tilted relative to the ball nut for allowing the deflecting members to be expanded when the deflecting members are expanded, a cooling agent flows through the zigzag shaped fluid flowing passage for cooling the ball nut and for preventing the ball nut from being overheated.
Abstract: A hydraulic cylinder device includes a cylinder, an axle and two blade units. The cylinder includes a chamber with a cross-sectional shape like a circle overlapping another circle. The axle is inserted through the cylinder. The axle includes two opposite grooves defined therein. Each of blade units includes a blade, a primary roller and a secondary roller. The blade is movably disposed in a related one of the grooves and made with a groove defined in a side close to an internal side of the cylinder. The secondary roller is disposed in the groove. The primary roller is disposed in the groove so that the primary roller is in contact with the secondary roller on one hand and in contact with the cylinder on the other hand.
Abstract: A dispensing gun includes a housing for holding a cartridge, a push rod engaged through the housing and having a plunger for engaging with the cartridge, an actuating plate engaged onto the push rod, a trigger pivotally secured to the housing and having an actuating pin for operating the actuating plate to move the push rod relative to the housing, a spring member biasing the actuating plate to engage with the actuating pin of the trigger, a latch engaged onto the push rod and biased to prevent the push rod from moving rearwardly relative to the housing when the actuating plate is released by the trigger, and a release member is located between the latch and the actuating pin of the trigger for being moved to release the push rod from the latch.
Abstract: An electric seal includes an antenna device engaged in a lock member and having a contact located in the lock member, a lock shaft engageable into the lock member and having a circuit board engaged in the bore of the lock shaft and having an RFID chip coupled to an electric circuit, the electric circuit includes a contact for electrically engaging with the contact of the antenna member when the lock shaft is engaged into the compartment of the lock member for identifying the RFID-based electric seal, the RFID chip do not generate and emit the signal to identify the electric seal when the lock shaft is disengaged from the lock member or when the circuit board is disengaged from the antenna member.
Abstract: A bicycle handlebar includes a cylinder having two collars formed on each end portion, two arms each having a barrel disposed between the collars, two bars engaged through the collars and the barrels of the arms for pivotally connecting the arms to the cylinder, and two followers engaged into the cylinder and movable relative to the cylinder for moving the barrels of the arms to clamp and retain the bars to the cylinder at the selected position and to retain the barrels of the arms at the selected angular position relative to the cylinder, the arms are adjustable relative to the cylinder to the selected angular position and the bars are movable relative to the cylinder to the selected position when the followers are released.
Abstract: A torque system of a power tool includes a combination of a first body and a second body, in which a toothed ring is assembled; and a mode selecting assembly, a torque adjusting module and control pins disposed on the second body. The torque system further includes restricting mechanisms formed on the second body, and the control pins are respectively disposed in the restricting mechanisms. One side of the control pin has a stopper block, and the restricting mechanism includes a first stopper, a second stopper and a through hole. When the control pin is driven to rotate and the stopper block faces the first stopper or the through hole, the object of switching each operation mode is achieved.
