Abstract
The utility model relates to a not only the stability in use is good, long service life's hydraulic torque wrench moreover, and it includes wrench body, pawl, ratchet, hydro -cylinder and round pin axle, install hydro -cylinder and ratchet and ratchet in the wrench body and be located hydro -cylinder below, the pawl upper end through round pin axle and the tailpiece of the piston rod of hydro -cylinder firstly be connected, lower extreme and ratchet mesh, the bore diameter who is equipped with T shape bush and T shape bush in the round pin shaft hole of pawl matches with round pin axle diameter. The advantage: hydraulic torque wrench not only stability in use is good, and life is longer moreover.
Description
Technical field
The utility model relates to one, and not only stability in use is good, and the hydraulic torque wrench of long service life, belongs to spanner and manufactures field.
Background technology
CN203510056U, title " a kind of hydraulic torque wrench with lock pawl ", include base, described base is provided with plinth, oil cylinder and force transmitting board are installed in described plinth, the piston rod external part of described oil cylinder is connected with force transmitting board, the bottom of described plinth is provided with driving shaft by ratchet, described ratchet coordinates with the ratchet transmission below force transmitting board, described plinth is also provided with the check pawl with ratchet fit inside, described check pawl and be provided with spring between force transmitting board and the plinth below it, the counter-force arm of inclination is provided with between the base at described oil cylinder rear and upper cylinder body, draw-in groove is provided with in the middle part of the rear end cap of described oil cylinder, the bottom of draw-in groove is installed with button pawl fixed head, hinged on described button pawl fixed head button pawl is installed, upper end and the draw-in groove of described button pawl fasten, lower end is arranged in counter-force arm, and be provided with extension spring between bottom and button pawl fixed head.Weak point: the hydraulic torque wrench of this kind of band lock pawl is when force transmitting board (ratchet) is to ratchet driving, because force transmitting board is subject to huge reaction force, easily make the force transmitting board pin shaft hole generation deformation of bearing pin and force transmitting board junction, thus the position of engagement changed between force transmitting board lower end ratchet and ratchet ratchet, between force transmitting board and ratchet, the change of the position of engagement gently then reduces the stability in use of spanner, heavy then directly damage spanner.
Utility model content
Purpose of design: for avoiding the deficiency in background technology, not only stability in use is good for design one, and the hydraulic torque wrench of long service life.
Design: for realizing above-mentioned purpose of design.Being provided with T-shaped lining in the pin shaft hole of 1, ratchet and the design of mating with pin diameter of the diameter of bore of T-shaped lining, is one of technical characteristic of the present utility model.The object of such design is: be provided with T-shaped lining in the pin shaft hole of ratchet and the diameter of bore of T-shaped lining mates with pin diameter, because T-shaped lining hardness is high, the power produced when ratchet Drive ratchet can not cause T-shaped lining to be out of shape, ensure that the position of engagement in use procedure between ratchet and ratchet, thus add stability in use and the service life of spanner.2, wrench body lower end is provided with reinforcement and reinforcement is positioned at design immediately below ratchet, is technical characteristic two of the present utility model.The object of such design is: wrench body lower end is provided with reinforcement and reinforcement is positioned at immediately below ratchet, and reinforcement strengthens wrench body lower end stress and bears intensity a little, thus enhances hydraulic torque wrench whole service life.
Technical scheme: a kind of hydraulic torque wrench, it comprises wrench body, ratchet, ratchet, oil cylinder and bearing pin, oil cylinder and ratchet are installed in described wrench body and ratchet is positioned at below oil cylinder, ratchet upper end is connected with the piston rod end of oil cylinder by bearing pin, lower end is engaged with ratchet, is provided with T-shaped lining and the diameter of bore of T-shaped lining mates with pin diameter in the pin shaft hole of described ratchet.
The utility model is compared with background technology, and hydraulic torque wrench not only stability in use is good, and longer service life.
