Abstract
A quickly operating adjustable spanner is composed of spanner body, special worm gear, accelerator and elastic switch. Said special worm gear consists of worm and gear. Said accelerator comprises drive gear and internal and external transmission gears. Said elastic switch is composed of switch knob, screw bolt, washer, spring, spring slot, fixing plate and cover. Its mouth can be quickly opened or closed by pressing or releasing the switch knob with locked-up position.
Description
The present invention relates to a kind of quick operating adjustable wrench of elastic switch that utilizes.
The tradition adjustable wrench uses the worm gear operating efficiency low, and can not latched position, very easily damages and pulls mouth.In decades, thousands of kinds of reform schemes are arranged both at home and abroad, but nobody can perfectly solve.
Purpose of the present invention, will provide a kind of exactly both can operate fast, elastic switch adjustable wrench that again can latched position, it need only press release knob, pulling mouth will magnify immediately, and the trip switch button is pulled mouth and can be bitten workpiece and latched position immediately, make and do not pull mouthful fragilely, therefore adjustable wrench obtains major technological breakthrough.
The object of the present invention is achieved like this: all the elastic switch adjustable wrench is formed by pulling body, extraordinary worm gear, accelerator and elastic switch.Pull body and comprise that pulling body surely pulls body two parts with moving, be provided with slide rail on the body pulling surely, be provided with sliding strong and tooth bar on the body moving pulling, motion in the sliding alive slide rail, pull a mouthful parallel folding, the worm gear of extraordinary worm gear and tooth bar engagement, elastic switch is by the rotation of the travelling gear control worm-gear toothing of accelerator, thus the folding that a mouthful E, F are pulled in control.Extraordinary turbine is made up of worm gear and worm-gear toothing, and both are connected as a single entity and for coaxial wheels, use a wheel shaft jointly.The secondary accelerator that accelerator is made up of driven wheel and travelling gear, wherein driven wheel links to each other with switch, and outer drive gears and interior travelling gear are installed on the power transmission shaft, are coaxial wheels; Driven wheel and outer drive gears engagement, interior travelling gear and worm-gear toothing engagement.Elastic switch by release knob, screw rod, packing ring, fixedly pull, spring, spring groove and outer cover form.The release knob inner hollow is fixed with a screw rod, and screw rod has two spiral arm of twining mutually to become twisted shape, and is similar to the spiral bit shape; The centre bore of driven wheel is not that circular hole but long waist shaped hole are enclosed within driven wheel on the screw rod, and driven wheel can only rotate and advance; Spring is put into spring groove, uses bolt will fixedly pull to be fixed on and pulls on the body; On the screw rod of gasket sleeve below driven wheel, again the screw rod end is inserted in the spring groove, use bolt that outer cover is fastened at last and pull on the body, switch installs; The external diameter of release knob should be smaller a little than the internal diameter of outer cover, should have good fitly between the two, and when pressing release knob, release knob bounces freely, and the axle center of screw rod keeps stable and do not play rolling, makes driven wheel and travelling gear good engagement all the time; Set turning to of spiral arm, when pressing release knob, pull and mouthful should open, and during the trip switch button.Release knob resets under the effect of spring force, and it is closed immediately to pull mouth.
Compare with an existing incision technology, compact conformation of the present invention is simple, but is active in one's movements fast, presses release knob and pulls and mouthful promptly open, it is promptly closed that the trip switch button is pulled mouth, realize at one stroke automation of operation, particularly behind the trip switch button, under elastic reaction, pulled a mouthful closure, workpiece there is a snap-in force, it is movable that worm gear location is difficult for, pull mouthful and workpiece between no longer occur skidding and damage the phenomenon of spanner, this is a technical quantum jump.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.
Fig. 1 is an elastic opening or closing fast adjustable wrench overall appearance schematic diagram.
Fig. 2 is an elastic opening or closing fast adjustable wrench optimum implementation structural representation.
Fig. 3 is the schematic diagram in driven wheel long waist shaped hole.
As shown in Figure 1, (1) is spanner, and (2) are extraordinary worm gear, and (3) are that accelerator, (4) are elastic switch.Slide rail (1.1A) is arranged pulling surely on the body (1.1), feather key (1.2A) and tooth bar (1.2B) is arranged on the body (1.2) moving pulling, sliding strong can slip automatically in slide rail, pull the parallel folding of a mouthful E, F.
As shown in Figure 2, (1) for pulling body, (2) are extraordinary worm gear.Extraordinary worm gear is made up of worm gear (2.1) and worm-gear toothing (2.2), and both are connected as a single entity is coaxial wheels, a shared wheel shaft (2.3).Accelerator (3) is made up of driven wheel (3.1), outer drive gears (3.2A), interior travelling gear (3.2B), interior outer drive gears is a coaxial wheels, a shared power transmission shaft (3.2C), driven wheel and outer drive gears engagement, interior travelling gear and worm-gear toothing are meshing.Release knob (4.1) inner hollow of switch (4) is fixed with a screw rod (4.2), and two spiral arm (4.2A), (4.2B) that twine are mutually arranged on the screw rod, and its shape is similar to the shape of fluted drill; The centre bore of driven wheel is not a circular hole, but long waist shaped hole (3.1A) or (3.1B) as shown in Figure 3, be enclosed within driven wheel on the screw rod, and driven wheel can only rotate and advance; Spring (4.5) is put into spring groove (4.6), using bolt will fixedly pull (4.4) above is fixed on and pulls on the body, be inserted in packing ring (4.3) on the screw rod below driven wheel, spring groove is inserted in the end of screw rod, use outer cover (4.7) bolted pulling on the body at last, switch installs.The external diameter of release knob should be smaller a little than the internal diameter of outer cover, presses release knob, and release knob should bounce freely, and the axle center of maintenance screw rod is stable does not play rolling, makes driven wheel and outer drive gears good engagement; Set turning to of spiral arm on the screw rod, pull when release knob is pressed and mouthful open, and during the trip switch button, release knob resets under the spring force effect, pulls a mouthful rapid closing.
