Abstract
The utility model relates to a chain saw guide board assembly which can absorb shock. The utility model is provided for providing a sawing device component having the advantages of shock reduction, noise reduction, service life extension, weight reduction and convenient operation. The utility model comprises a middle plate and two side plates, wherein the middle plate is provided with a plurality of through first slotted holes, and each side plate is provided with a plurality of through second slotted holes corresponding to the first slotted holes. The two side plates are arranged on the two opposite sides of the middle plate, and the middle plate is clamped between the two side plates. A guide channel for guiding the saw chain is formed between the side plates and the outer periphery of the middle plate, and the first slotted holes on the middle plate and the second slotted holes on the two side plates are communicated.
Description
Technical field
The utility model belongs to the sawing device parts, but a kind of chain saw guide plate assembly of weakening particularly.
Background technology
As shown in Figure 1 and Figure 2, a kind of chain saw of commonly using 1 comprises housing 2, is locked on guide plate assembly 3 on the housing 2, is located in sprocket gear 4 on the housing 2, is located in runner 5 and saw chain 6 on the side plate 302.
Guide plate assembly 3 has the side plate 302 that middle plate 301 and two is arranged at two opposition sides of middle plate 301.Form the guide channel 303 of using this saw chain 6 of guiding between the outside of side plate 302 and middle plate 301.
Saw chain 6 comprises most drive divisions 601, most connecting portion 602 and most blade part 603 of being located at connecting portion 602 outsides that connects drive division 601.
When the two ends of saw chain 6 were sheathed on sprocket gear 4, the runner 5, drive division 601 was to be slidably connected in the guide channel 303 on it, and the bottom of connecting portion 602 system supports on the outer peripheral edges of side plate 302.
So, when sprocket gear 4 drives saw chain 6 rotations via most drive divisions 601, support guiding saw chains 6 by guide plate assembly 3, and carry out cutting operation by most blade parts 603 on it.
Though, can reach the purpose that supports guiding saw chain 6 by guide plate assembly 3,, on reality was used, guide plate assembly 3 did not have the relevant design of shaking that keeps away.Therefore, when saw chain 6 rotations cause the bottom of most connecting portions 602 to knock the outer peripheral edges of side plate 302, vibrational energy can direct outer peripheral edges by side plate 302 be passed to guide plate assembly 3 inside toward in, and then cause the 1 whole lasting vibration that produces of guide plate assembly 3 interlock chain saws, and produce harsh noise.So, not only can cause the operational difficulty of user, more can make the user tired easily; And chain saw 1 also produces the situation of damaging because of vibration problem easily; In addition, guide plate assembly 3 has suitable weight usually and span is long again, and therefore when user's long-time operation, the weight regular meeting of guide plate assembly 3 causes burden greatest on user's muscle power.
Summary of the invention
But the purpose of this utility model provides and a kind ofly reduces vibration, reduces noise, weight reduction, is convenient to the chain saw guide plate assembly of the weakening operating, increase the service life.
Plate and biside plate during the utility model comprises; Offer most shape first slotted eyes that connect on the middle plate; Offer second slotted eye most and the corresponding perforation shape of first slotted eye on the side plate; Two opposition sides of plate during biside plate system is arranged at so that middle plate is located between the biside plate, form the guide channel of guiding saw chain between the outside of side plate and middle plate, and in making on the plate on first slotted eye and the biside plate second slotted eye be connected state.
Wherein:
In on the plate on first slotted eye and the biside plate second slotted eye be corresponding circle.
In on the plate on first slotted eye and the biside plate second slotted eye be corresponding strip.
Most first slotted eyes are offered with the shape that is interspersed on the middle plate.
Most second slotted eyes are offered with the shape that is interspersed on the biside plate.
Because plate and biside plate during the utility model comprises; Offer most shape first slotted eyes that connect on the middle plate; Offer second slotted eye most and the corresponding perforation shape of first slotted eye on the side plate; Two opposition sides of plate during biside plate system is arranged at so that middle plate is located between the biside plate, form the guide channel of guiding saw chain between the outside of side plate and middle plate, and in making on the plate on first slotted eye and the biside plate second slotted eye be connected state.During assembling, the utility model is locked on the housing of chain saw; Sprocket gear is located on the housing; Runner shaft is located on the biside plate; Comprise when the connecting portion of most drive divisions, most connection drive divisions and the saw chain two ends that majority is located at the blade part in the connecting portion outside are sheathed on sprocket gear, the runner, drive division system is slidably connected in the guide channel on it, and the bottom system of connecting portion supports on the outer peripheral edges of side plate; During operation, when sprocket gear drives the saw chain rotation via most drive divisions, support the guiding saw chain, and carry out cutting operation by most blade parts on it by the utility model.When saw chain rotates, when causing the bottom of most connecting portions to knock the outer peripheral edges of side plate, side plate is by offering that most thereon second slotted eyes form an amount of flexibility and an amount of distortion that produces, with absorption, dissipation vibrational energy, more can intercept vibrational energy and directly be passed to inside toward in by the outer peripheral edges of biside plate; Can reduce effectively that chain saw is whole to be continued to produce vibration and reduce noise, and reduce the user, and alleviate whole weight, can effectively reduce the burden on user's muscle power because of produced tired of vibration and the situation damaged.Not only reduce vibration, reduce noise, increase the service life, and weight reduction, be convenient to operation, thereby reach the purpose of this utility model.

The specific embodiment
Embodiment one
As shown in Figure 4, but the chain saw guide plate assembly 100 of the utility model weakening is to be assembled on the chain saw 200 that comprises housing 210, sprocket gear 220, runner 230 and saw chain 240.
As Fig. 3, Fig. 4, shown in Figure 5, but the chain saw guide plate assembly 100 of the utility model weakening comprises middle plate 10 and biside plate 20.
Offer most rounded perforation shape first slotted eyes 11 with the shape that is interspersed on the middle plate 10.
Offer second slotted eye 21 of most and rounded perforation shapes corresponding on the side plate 20 with first slotted eye 11 with the shape that is interspersed.
Biside plate 20 is two opposition sides of plate 10 in being arranged at, so that middle plate 10 is located between the biside plate 20, form the guide channel 22 of guiding saw chain 240 between the outside of side plate 20 and middle plate 10, and in the order on the plate 10 on first slotted eye 11 and the biside plate 20 second slotted eye 21 be connected state.
During assembling, but the chain saw guide plate assembly 100 of the utility model weakening is to be locked on the housing 210; Sprocket gear 220 is to be located on the housing 210; Runner 230 is to be located on the biside plate 20; Saw chain 240 comprises most drive divisions 241, most connecting portion 242 and most blade part 243 of being located at connecting portion 242 outsides that connects drive division 241.
