The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
Electric chain saw chain tensioner that Fig. 1～Fig. 3 provides for the present embodiment and guide plate clamp device structural representation, described
Electric chain saw chain tensioner and guide plate clamp device include tensioner knob 1, have female tensioner knob inserts 2 and are embedded in tensioner
In knob 1, tensioner knob elastic component 3, expansion tightening wheel 4 are sequentially sleeved on tensioner knob inserts 2, and tensioner knob elastic component 3 is positioned at
Near the side of tensioner knob 1, fixed with tensioner knob 1 by cover plate 7 outside expansion tightening wheel 4.Cover plate 7 inwall circumference uniformly has
Locating slot, lock knob 5 one end snaps in the locating slot of cover plate 7, and lock knob 5 other end coordinates with the gear of expansion tightening wheel 4, and lock knob 5 is internal
It is installed with lock knob elastic component 6.Tensioner cam 9 is positioned at outside cover plate 7, and with expansion tightening wheel 4 location fit.
In the present embodiment, lock knob 5 and lock knob elastic component 6 are 3 sets.In actually used, lock knob 5 and lock knob elastic component 6 can be 3
More than set, arrange the most voluntarily.
Cover plate 7 is fastenedly connected with tensioner knob 1 by sunk screw.
Tensioner cam 9 is fastenedly connected by sunk screw with expansion tightening wheel 4.
Tensioner knob elastic component 3, lock knob elastic component 6 are all helical spring.
In conjunction with Fig. 4 and Fig. 5, Electric chain saw chain tensioner and guide plate clamp device that the present embodiment provides are arranged on electricity when using
On chain saw.In the agent structure 16 of electric chain saw, the guide plate 12 becoming 3 °～8 ° obliquely is installed, in the peripheral embedding of guide plate 12
Chain 11.Equipped with block pad 13, oil seal gasket 14 between agent structure 16 and guide plate 12, and fixed by clamp nut 15.Guide plate
12 can be along guide groove transverse shifting, and guide groove is embedded on block pad 13, and guide groove becomes 3 °～8 ° with horizontal line.The side of chain 11 with
Sprocket wheel 17 engages, and rotates around guide plate 12 circumference.
The peripheral part of the sprocket wheel 17 etc. that guide plate 12 and the chain 11 that coordinate peripheral with guide plate 12 engage with chain 11 is whole
Pusher side plate 8 covers, and this complete machine side plate 8 is installed in tensioner cam 9 and the cover plate 7 of Electric chain saw chain tensioner and guide plate clamp device
Between, complete machine side plate 8 is fixed in agent structure 16 simultaneously.Equipped with block 10 between tensioner cam 9 and guide plate 12, tensioner cam 9,
Block 10, guide plate 12 are connected by screw.Equipped with sprocket wheel pad 18, collar 19 between sprocket wheel 17 and complete machine side plate 8.
Chain tensioner and clamp device and complete machine side plate 8, be fixed by clamp nut 15 together.Block pad 13 passes through
Screw is fixed in agent structure 16, and block pad 13 has horizontal two lug, guide plate 12 and two on block pad 13
Lug laterally coordinates, and guide plate 12 is fixed longitudinally through fastening hex nut.Having two lugs before and after block 10, rear lug snaps in leads
In the draw-in groove of plate 12, front lug laterally coordinates with the tensioner cam 9 of chain tensioner and guide plate clamp device, and by rotating tensioner
Knob 1 reaches so that tensioner cam 9 coordinates, so that chain is able to horizontal tensioner with the front lug driving of block 10.
Rotate tensioner knob 1, coordinated with expansion tightening wheel 4 gear by lock knob 5, driving tensioner cam 9 around axial-rotation, from
And drive guide plate 12 along guide groove transverse shifting；When chain 11 horizontal tensioner, while continuing rotary knob 1, knob 1 is axial
Compression knob elastic component 3 axially-movable so that guide plate 12 more fastens.
The Electric chain saw chain tensioner of the present embodiment offer and guide plate clamp device, by rotating tensioner knob 1, will make to lead
Plate 12 does the motion in level relative to sprocket wheel 17, so that chain 11 tensioner, the horizontal tensioner of guide plate 12；Simultaneously by axially
Tensioner knob elastic component 3 so that guide plate 12 axially fastens.Use the simplest, it is easy to operation.
Electric chain saw chain tensioner and the principle of guide plate clamp device that the present embodiment provides are as follows:
The design of tensioner knob elastic component 3 according to the requirement of the expanding force of chain saw chain, the degree of tightness of chain by 3 and more than
The size of frictional force that coordinates with locking wheel 4 gear of lock knob 5 determine；The size of frictional force is strong by tensioner knob elastic component 3
The intensity of degree and lock knob elastic component 6 determines, the therefore chain tensioner when rotating to gear slipping.
In real work, rotating tensioner knob 1 counterbore and guide tensioner knob inserts 2 concentric with hex bolts, screw thread revolves
Tight about one week, now guide plate 12 did not compress, and tensioner cam 9 cylindrical and block 10 lugs contact, along with the axle of tensioner cam 9
To rotation, tensioner cam 9 cylindrical and block 10 lugs contact, promote guide plate 12 along spacing movement.When continuing to rotate tensioner rotation
During button 1, guide plate 12 is more than the driving force of lock knob 5 and expansion tightening wheel 4 to the resistance of tensioner cam 9, and expansion tightening wheel 4 skids, tensioner cam 9
Stop operating, guide plate 12 the most further horizontal movement tensioner chain；Chain now is in optimal tensioner state, continues rotation
Turn tensioner knob 1, owing to the design of tensioner knob elastic component 3 makes expansion tightening wheel 4 be in slipping state, so tensioner cam 9 is not
Being rotated further by, now tensioner knob inserts 2 section starts to contact with guide plate 12, starts to compress guide plate 12, until guide plate 12 compresses is
Only.
Long-time use after, coordinate sound and strength by experience lock knob and expansion tightening wheel in tensioner knob, it is possible to clearly
Feeling to Chu sprocket wheel whether tensioner, whether guide plate fastens.
