Description
Technical field
The present invention relates to a kind of adjustable wrench of quick regulation.
Background technology
Common adjustable wrench by turbine adjust side movable chela grip objects, thumb regulation scroll bar be,
Palm needs as far as possible forward, same position to be almost in chela, very uncomfortable, and because regulation scroll bar only drives side
Movable chela, it is necessary to compare firmly, and after decontroling thumb, turbine easily occur it is a small amount of retract, chela is easily with being pressed from both sides
Object departs from, and thumb needs to pin nut always, and operation is very inconvenient.
The content of the invention
The technical problem to be solved in the present invention and the technical assignment proposed are prior art to be improved with being improved,
A kind of adjustable wrench of quick regulation is provided, for the purpose of facilitating regulation, lifting operation validity.Therefore, the present invention take with
Lower technical scheme.
A kind of adjustable wrench of quick regulation, including for hand-held spanner handle, be arranged at that spanner handle is anterior to be used to adjust
The regulation scroll bar of jaw of spanner size, the left chela for forming jaw of spanner and right chela, described left chela and right chela
Symmetrical to be connected on the anterior connecting plate of spanner handle, the rear portion of described left chela passes through left gear bar and transmission turbine
The bar connecting plate anterior with spanner handle is connected, and is between described left gear bar and transmission turbine rod and left chela and connecting plate
It is rotatably connected, the rear portion of described right chela is connected by right gear bar and light the connecting rod connecting plate anterior with spanner handle, institute
It is to be rotatably connected between the right gear bar and light connecting rod and right chela and connecting plate stated, described regulation scroll bar and transmission whirlpool
Take turns bar engagement, described left gear bar and the engagement of right gear bar.Scroll bar is adjusted by rotating, transmission turbine rod rotation is driven, leads to
Crossing bar linkage structure makes left chela produce rotation, and drives left gear bar to rotate, and left gear bar drives right gear bar to rotate again, passes through
The light connecting rod of right chela rear end connection, makes right chela symmetrically clamp or deploy with left chela, and more convenient operation is more laborsaving, and
And because centre is by worm gear drive, self-locking performance is preferable when without external force, reduces the degree for chela rollback occur.
As further improving and supplementing to above-mentioned technical proposal, present invention additionally comprises following additional technical feature.
Described left chela and right chela are located at two outsides of connecting plate, and described left gear bar is parallel with transmission turbine rod
Set, described right gear bar and light connecting rod are be arranged in parallel, and described left gear bar and right gear bar are symmetrical set, described
Transmission turbine rod and light connecting rod to be symmetrical set.By left chela and right chela being connected to two outsides of connecting plate,
Make chela that there is larger space in rotary moving, pass through left gear bar, transmission turbine rod, right gear bar and the light be arrangeding in parallel
4 symmetrical and arranged in parallel rod drive mechanisms of connecting rod, the clamping force for the offer chela that can stablize, make chela be easier to grab
Tight object.
Described left chela and right chela symmetrical shape, left chela and right chela are including anterior cleft hand and postmedian
Pawl arm, described pawl arm are straight-arm parallel to each other.By being symmetrical arranged on left chela and right chela planform, can make
The chucking power of left chela and right chela is more steady, it is easier to promptly object.
Described left chela and the rear portion of right chela offer the chela groove that left and right is run through, the upper and lower of described connecting plate
To middle part offer the connection board slot that runs through of left and right, described left gear bar, transmission turbine rod, right gear bar and light connecting rod are equal
It is connected to by the way that rivet is rotatable in connection board slot and chela groove.Company is arranged at by the way that transmission turbine rod etc. is driven parts
In fishplate bar groove and chela groove, make junction not exposed, not only add aesthetics, and human body is less easily accessible to connecting portion
Position, it is safer, it is rotatably connected by rivet, technology maturation, cost is low.
Described left gear bar, transmission turbine rod, right gear bar and light connecting rod is flat rod, described left gear bar,
One end that transmission turbine rod and right gear bar are connected with connecting plate is gear shape, the end being connected with left chela or right chela
It is semi-circular shape, the both ends of described light connecting rod are semi-circular shape.Flat rod structural thickness is small, can easily set
In connection board slot and chela groove, make connecting portion not exposed, the end being connected with left chela or right chela is semi-circular shape, is made
Spanner is safer when being touched with human body.
The left part of described regulation scroll bar is the volute bar engaged with transmission turbine rod, and the right part for adjusting scroll bar is for hand
The right thumb wheel dialled, the periphery of described right thumb wheel are provided with the circular tooth form striped that left and right is laterally set.Regulation scroll bar only needs a left side
Portion realizes the drive connection with transmission turbine rod, and the circular tooth form striped of right part is easier hand and dials rotation regulation.
Described transmission turbine rod and the tooth form that engage of regulation scroll bar are the oblique tooth that is matched with volute bar.With adjusting scroll bar
The oblique tooth of engagement can provide bigger driving torque than straight-tooth, more laborsaving, and the self-locking performance in the case of without external force is more
It is good.
The spanner handle at described connecting plate rear is provided with runs through rectangular through holes, institute for accommodating regulation the upper and lower of scroll bar
The regulation scroll bar stated is rotatable to be embedded in rectangular through holes.Regulation scroll bar is embedded in rectangular through holes by pivot pin,
It is less likely to be damaged regulation scroll bar when falling, colliding, and it is compact in structure, and be conveniently replaceable maintenance and adjust
Save scroll bar.
The rear end of described spanner handle is provided with circular hanging hole.Circular hanging hole easily can be such that spanner is hung on metope,
Space hold is reduced when usually placing.
The width at the middle part of described spanner handle is less than rear portion and front width, and the rear end of described spanner handle is semicircle
Shape, the side at the holding position of the postmedian of spanner handle is semicircle cambered surface, and the front end both sides of described connecting plate are vertical
Circular arc obtuse angle.The width at the middle part of spanner handle is less than rear portion and front width is easy to hold, and passes through the circle to crest line and end
Arcing processing, on the one hand can save material, also improve spanner handle and security during human contact.
Beneficial effect：Thumb when this spanner reduces regulation is exerted oneself degree, and turbine is not easy to retract after regulation,
Because compared with conventional spanner, the change in structure extends the pawl arm of chela, when thumb is to regulation scroll bar operation, palm
It will not forward extend out the front portion of chela, more convenient operation, more easily.
