Fig. 1~Fig. 3 be Electric chain saw chain tensioner provided in this embodiment and guide plate clamp device structural schematic diagram, it is 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 located at
Close to the side of tensioner knob 1,4 outside of expansion tightening wheel is fixed by cover board 7 and tensioner knob 1.7 inner wall of cover board is circumferentially uniformly provided with
Locating slot, 5 one end of lock knob are caught in the locating slot of cover board 7, and 5 other end of lock knob and the gear of expansion tightening wheel 4 coordinate, inside lock knob 5
It is installed with lock knob elastic component 6.Tensioner cam 9 is located at the outside of cover board 7, and with 4 location fit of expansion tightening wheel.
In the present embodiment, lock knob 5 and lock knob elastic component 6 are 3 sets.In actual use, lock knob 5 and lock knob elastic component 6 can be 3
More than set, voluntarily it is arranged as needed.
Cover board 7 is fastenedly connected by sunk screw and tensioner knob 1.
Tensioner cam 9 is fastenedly connected with expansion tightening wheel 4 by sunk screw.
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 provided in this embodiment and guide plate clamp device are mounted on electricity when using
On chain saw.In the agent structure 16 of electric chain saw, the guide plate 12 obliquely at 3 °~8 ° is installed, it is embedded in the periphery 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 fastening nut 15.Guide plate
12 can be along guide groove transverse shifting, and guide groove is on block pad 13, and guide groove is with horizontal line at 3 °~8 °.The side of chain 11 with
Sprocket wheel 17 engages, and is rotated around 12 peripheral part of guide plate.
Guide plate 12 and whole with the peripheral portion of the chain 11 of the periphery of guide plate 12 cooperation, the sprocket wheel 17 engaged with chain 11 etc.
Pusher side plate 8 covers, which is installed in tensioner cam 9 and the cover board 7 of Electric chain saw chain tensioner and guide plate clamp device
Between, while complete machine side plate 8 is fixed in agent structure 16.Between tensioner cam 9 and guide plate 12 be equipped with block 10, tensioner cam 9,
Block 10, guide plate 12 pass through screw connection.Equipped with sprocket wheel gasket 18, retainer ring 19 between sprocket wheel 17 and complete machine side plate 8.
Chain tensioner and clamp device and complete machine side plate 8, are fixed by fastening nut 15 together.Block pad 13 passes through
Screw is fixed in agent structure 16, has two lateral lugs, guide plate 12 and two on block pad 13 on block pad 13
Lug laterally coordinates, and guide plate 12 is fixed longitudinally through fastening hex nut.Block 10 is front and back, and there are two lugs, and rear lug, which is caught in, leads
In the card slot of plate 12, preceding 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 and the preceding lug driving of block 10 coordinate, so that chain is able to horizontal tensioner.
Rotate tensioner knob 1, coordinated by lock knob 5 and 4 gear of expansion tightening wheel, driving tensioner cam 9 around axial-rotation, from
And drive guide plate 12 along guide groove transverse shifting；When the lateral tensioner of chain 11, while continuing turn knob 1, knob 1 is axial
It compresses knob elastic component 3 to be axially moved so that guide plate 12 more fastens.
Electric chain saw chain tensioner provided in this embodiment and guide plate clamp device will to lead by rotating tensioner knob 1
Plate 12 does the movement in level relative to sprocket wheel 17, so that 11 tensioner of chain, the lateral tensioner of guide plate 12；Pass through axial direction simultaneously
Tensioner knob elastic component 3 so that guide plate 12 axially fastens.It is easily operated using upper very simple.
Electric chain saw chain tensioner provided in this embodiment and the principle of guide plate clamp device are as follows：
The design of tensioner knob elastic component 3 leans on 3 or more according to the requirement of the expanding force of chain saw chain, the elastic of chain
The size of frictional force of lock knob 5 and 4 gear of locking wheel cooperation 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, therefore the chain tensioner when rotating to gear slipping.
In actual operation, 1 counterbore guiding tensioner knob inserts 2 of rotation tensioner knob is concentric with hex bolts, screw thread rotation
Tight one week or so, at this time guide plate 12 do not compress, 9 outer circle of tensioner cam and 10 lugs contact of block, with the axis of tensioner cam 9
To rotation, 9 outer circle of tensioner cam and 10 lugs contact of block push guide plate 12 to be moved along limit.It is revolved when continuing rotation tensioner
When button 1, guide plate 12 is more than the resistance of tensioner cam 9 driving force of lock knob 5 and expansion tightening wheel 4, and expansion tightening wheel 4 skids, tensioner cam 9
It stops operating, the not further horizontal movement tensioner chain of guide plate 12；Chain at this time is in best tensioner state, continues to revolve
Turn tensioner knob 1, since the design of tensioner knob elastic component 3 makes expansion tightening wheel 4 be in slipping state, so tensioner cam 9 is not
It is rotated further by, 2 section of tensioner knob inserts starts to contact with guide plate 12 at this time, starts to compress guide plate 12, until the compression of guide plate 12 is
Only.
After long-time use, by the cooperation sound and strength of experiencing lock knob and expansion tightening wheel in tensioner knob, so that it may with clear
Feel to Chu sprocket wheel whether tensioner, whether guide plate fasten.
