Technological scheme of the present invention:
A kind of locking quick-detachable lock, is characterized in that, comprise outer lock 1, Compress Spring 2, interior lock 3, lateral pin 4, packing ring 5 and pinning 6 and form; Outer lock 1 is drum-shaped, opening edge marginal zone flange, has two symmetrical Pear Shaped holes, for the assembling of lateral pin 4 by opening end both sides; Compress Spring 2 is in compressive state after assembling; Interior lock 3 is drum-shaped, and edge of opening has oval auricle, and circular hole is opened at auricle two ends, for the installations such as structure mouth frame, have two symmetrical waist shaped holes by opening end both sides, for the radial motion along interior lock 3 of the assembling of lateral pin 4 and lateral pin 4; Lateral pin 4 is cylindrical, and respectively there are two place's symmetrical grooving at two ends, assembles rear restriction move along the radial for lateral pin 4; Packing ring 5 original state band sink, flare, need will to sink pressing, make it ringwise, deviate to prevent it from pinning 6 during assembling with instrument; Pinning 6 is in solid of rotation, helical slot is had bottom it, helical slot changes (down turning) to peak rear screw shape fluting direction, a groove is formed at slotted distal (spiral rotating 90 °), groove is used for blocking lateral pin 4, prevent the rotation of pinning 6, its head has cross bath (identical with common crisscross screw structure), can be used for instrument (common in-line and Philips screwdriver) to open and locking pinning 6, as needs, also can change pinning 6 head into common butterfly by cross flute profile, unlatching and locking can without instruments.
Its assembly relation of quick-detachable lock of the present invention is made up of lock assembly, pinning assembly.Lock assembly is made up of outer lock 1, Compress Spring 2, interior lock 3, lateral pin 4.Lock 3 in installing again after Compress Spring 2 being installed on outer lock 1 inside, finally installs lateral pin 4 between interior lock 1, outer lock 3.Because the Pear Shaped perforate of outer lock 1 is made up of a big circle cutting (diameter is more bigger than lateral pin diameter) and kidney-shaped minor diameter perforate (diameter is more smaller than lateral pin diameter), whole lateral pin 4 is by the big circle cutting place of outer lock 1 Pear Shaped perforate, and kidney-shaped minor diameter perforate part can only pass through the fluting place of lateral pin 4, for lateral pin 4 moving and limiting lateral pin 4 moving along himself radial direction along outer lock 1 radial direction; Kidney-shaped perforate on interior lock 3 (diameter is more bigger than lateral pin 4 diameter) also by whole lateral pin 4, for lateral pin 4 moving (move distance depends on interior lock waist shaped hole length) along interior lock 3 radial direction; After lock assembled is good, under the elastic force effect of Compress Spring 2, lateral pin 4 slotted section is positioned at kidney-shaped minor diameter tapping upper end and the lock 3 kidney-shaped perforate lower end of the perforate of outer lock 1 Pear Shaped all the time, because the kidney-shaped minor diameter tapping diameter of outer lock 1 Pear Shaped perforate is less than lateral pin 4 diameter, so lateral pin 4 can not be deviate from from lock assembly.Pinning assembly is made up of packing ring 5 and pinning 6.Pinning 6 is arranged on after on dome structure (as spring sheet) and loads in pinning 6 by packing ring 5 again, finally flatten sagging for packing ring 5 with instrument, packing ring 5 diameter of bore is reduced, ensures that packing ring 5 cannot be deviate from from pinning 6, thus pinning assembly cannot be deviate from from dome structure.Again pinning assembly is arranged on dome structure after lock assembly being arranged on structure mouth frame, a whole set of quick-detachable lock and installation.
Quick-detachable lock locking principle of the present invention is: pin with screw-driver and rotate pinning 6, because pinning 6 has spiral slot, lateral pin 4 can only along the axial motion of lock assembly simultaneously, when rotating pinning 6 again after pinning 6 spiral slot aligning (blocking) lateral pin 4, lateral pin 4 is along pinning 6 axial motion, and in pinning 6 rotation process under the effect of Compress Spring 2 elastic force lateral pin 4 be applied to pinning 6 one axial pressures all the time, when pinning 6 half-twist, lateral pin 4 revolves and turns in pinning 6 groove, thus realizes the locking of quick-detachable lock.Because locking state pinning 6 bottom end face withstands bottom interior lock 3 all the time, haveing nothing to do without Compress Spring under responsive to axial force 2 elastic force and decker sandwich thickness, namely quick-detachable lock coupling mechanism force and decker sandwich thickness have nothing to do, and effectively can solve general quick-detachable lock pinning length and not mate the excessively loose of generation or tension problem with thickness of interlayer.
Quick-detachable lock open theory of the present invention is: pin pinning 6 with screw-driver, along locking reverse direction by pinning 6 half-twist, now the helical slot of pinning 6 cannot block lateral pin 4 again, and lateral pin 4 cannot be applied to pinning 6 active force again, can realize the unlatching of quick-detachable lock.
Beneficial effect of the present invention:
Quick-detachable lock structure of the present invention is simple, lightweight, size is little, beautiful shape, reliability are high, easy accessibility.Compared with general quick-detachable lock, coupling mechanism force and the decker sandwich thickness of the generation of locking rear spring power are substantially irrelevant, and general quick-detachable lock can be avoided easily to eject problem in vibration compared with connecting the loosening pinning caused under rugged environment.
