The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6; A kind of chain saw disclosed by the invention with the protective plate detent mechanism; Comprise chain saw housing 1, be articulated in protective plate 2 and protective plate detent mechanism on the chain saw housing 1; Said protective plate detent mechanism comprises the locking knob 3 that is hinged on the chain saw housing 1 and is located at and is used to locate the screens structure that protective plate is pulled the position between protective plate 2 hinged ends and the locking knob; Be provided with elastic component 4 between said locking knob 3 and chain saw housing, thereby said elastic component turns to the protective plate hinged end to make screens structural elasticity chucking locking knob elasticity.Said screens structure comprises the driving lever 5 that is located at protective plate 2 hinged ends, and an end of driving lever 5 corresponding locking knobs 3 is provided with some spacing draw-in grooves 51, and locking knob 3 is provided with the detent projection 32 with said spacing draw-in groove engagement.Preferably one of the volume cost embodiment of said detent projection 32.
Said protective plate 2 lower ends are provided with driving lever 5, and protective plate 2 constitutes spacing the cooperation through driving lever 5 with locking knob 3.Described protective plate 2 can divide with driving lever 5 and is arranged, assembling then, and present embodiment is for making reliable operation, and said driving lever 5 and protective plate 2 are wholely set.Said protective plate 2 is 5 ~ 8 with the length ratio of driving lever 5.
The said driving lever 5 of present embodiment is provided with respect to the other end with protective plate 2 links and is used for and the locking knob 3 spacing spacing draw-in grooves 51 that cooperate.Spacing draw-in groove 51 on the said driving lever 5 can be provided with according to actual needs, and present embodiment preferably is provided with the spacing draw-in groove 51 of two " V " fonts, and said two spacing draw-in groove 51 adjacent settings also constitute " W " font structure together.The top of the face that said two spacing draw-in grooves 51 intersect can be arc transition, and the present embodiment preferably top of the face that intersects of two card stopper slots is pointed structure, 30 ° ~ 60 ° of the angles that two faces of said spacing draw-in groove 51 and the direction of rotation of driving lever 5 become.
Said locking knob 3 one ends are provided with and are used for the convex tendon 31 that is connected with elastic component 4; Said elastic component 4 one ends are socketed on the convex tendon 31; The other end is fixedly connected with chain saw housing 1, and reliable for elastic component 4 is connected, the described convex tendon 31 of present embodiment is " ten " font structure.
The described elastic component 4 of present embodiment can be arranged to torsion spring or elastomeric pad, and is accurate for making the Thrust Control of protective plate 2, good stability, and present embodiment is compression spring preferably.Its advantage is accurately to control the thrust of protective plate 2 through the number of turns, line footpath and the length of regulating the compression spring.Thrust Control is easy to adjust between 20N ~ 60N, and protective plate 2 adopts the high-strength engineering plastic processing and manufacturing with locking knob 3 simultaneously, and production efficiency is high, and production cost is low.
During practical application, like Fig. 1, shown in Figure 2, said protective plate 2 is in the lockup state that resets, and compression spring 4 compresses locking knob 3, a spacing draw-in groove 51 of the detent projection 32 chucking driving levers 5 of locking knob 3, and protective plate 2 is by locking.When the outside applies a force urges protective plate 2 of pushing to; A face of a face extruding locking knob 3 of the spacing draw-in groove 51 of driving lever 5; Cause these two compressive planes to relatively move, because protective plate 2 and locking knob 3 all are through being hingedly fixed on the chain saw housing 1, at this moment locking knob 3 is with respect to the direction of rotation motion of protective plate 2; At this moment compress spring 4 and react on power opposite of protective plate 2 generations with thrust through locking knob 3; This is exactly the protective plate thrust that needs control, in case the detent projection 32 of locking knob 3 is crossed the crossing face between two spacing draw-in grooves spacing 51 of driving lever 5, will slip into another spacing draw-in groove 51 of driving lever 5 rapidly; Locking protective plate 2 is like Fig. 3, shown in Figure 4.
The foregoing description is to specific descriptions of the present invention; Only be used for the present invention is further specified; Can not be interpreted as the qualification to protection domain of the present invention, the technician of this area according to the content of foregoing invention the present invention is made some nonessential improvement and adjustment all falls within protection scope of the present invention.
