Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of chain saw with protective plate detent mechanism disclosed by the invention, comprise chain saw housing 1, be articulated with protective plate 2 and protective plate detent mechanism on chain saw housing 1, described protective plate detent mechanism comprises the locking knob 3 being hinged on chain saw housing 1 and is located at the retaining structure of pulling position between protective plate 2 hinged ends and locking knob for locating protective plate, between described locking knob 3 and chain saw housing, be provided with elastic component 4, thereby described elastic component turns to protective plate hinged end to make retaining structure elasticity clamping locking knob elasticity.Described retaining structure comprises the driving lever 5 that is located at protective plate 2 hinged ends, and one end of the corresponding locking knob 3 of driving lever 5 is provided with some spacing draw-in grooves 51, and locking knob 3 is provided with the detent projection 32 engaging with described spacing draw-in groove.Preferably one of the volume cost embodiment of described detent projection 32.
Described protective plate 2 lower ends are provided with driving lever 5, and protective plate 2 forms spacing cooperation by driving lever 5 with locking knob 3.Described protective plate 2 can divide and be arranged with driving lever 5, then assembling, and the present embodiment is for making reliable operation, and described driving lever 5 is wholely set with protective plate 2.Described protective plate 2 is 5 ~ 8 with the Length Ratio of driving lever 5.
Described in the present embodiment driving lever 5 with respect to the other end of protective plate 2 links be provided with for the spacing spacing draw-in groove 51 coordinating of locking knob 3.Spacing draw-in groove 51 on described driving lever 5 can arrange according to actual needs, and the present embodiment preferably arranges the spacing draw-in groove 51 of two " V " fonts, and the adjacent setting of described two spacing draw-in grooves 51 also forms " W " character form structure together.The top of the crossing face of described two spacing draw-in grooves 51 can be arc transition, and the present embodiment preferably tops of the crossing face of two card stopper slots is pointed structure, 30 ° ~ 60 ° of the angles that two faces of described spacing draw-in groove 51 become with the direction of rotation of driving lever 5.
Described locking knob 3 one end are provided with the convex tendon 31 for being connected with elastic component 4, described elastic component 4 one end are socketed on convex tendon 31, the other end is fixedly connected with chain saw housing 1, reliable for elastic component 4 is connected, and the convex tendon 31 described in the present embodiment is " ten " character form structure.
Elastic component 4 described in the present embodiment can be arranged to torsion spring or elastomeric pad, accurate for making the thrust control of protective plate 2, good stability, and the present embodiment is compression spring preferably.Its advantage is can be by regulating the number of turns, wire diameter and the length of Compress Spring accurately to control the thrust of protective plate 2.Thrust is controlled between 20N ~ 60N easy to adjust, simultaneously protective plate 2 and locking knob 3 adopt high-strength engineering plastic processing and manufacturing, and production efficiency is high, and production cost is low.
When practical application, as shown in Figure 1 and Figure 2, described protective plate 2 is in reset lockup state, and Compress Spring 4 compresses locking knob 3, and the detent projection 32 of locking knob 3 clamps a spacing draw-in groove 51 of driving lever 5, and protective plate 2 is by locking.When outside apply one push to try hard to recommend moving protective plate 2 time, 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 are all by being hingedly fixed on 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 reacts on protective plate 2 by locking knob 3 and produces a power contrary with thrust, this is exactly the protective plate thrust that needs control, once the detent projection 32 of locking knob 3 is crossed the phase cross surface between two spacing draw-in grooves spacing 51 of driving lever 5, will slip into rapidly another spacing draw-in groove 51 of driving lever 5, locking protective plate 2, as Fig. 3, shown in Fig. 4.
Above-described embodiment is to specific descriptions of the present invention; only be used to further illustrate the present invention; can not be interpreted as limiting the scope of the present invention, the technician of this area according to the content of foregoing invention to the present invention make some nonessential improvement and adjust all fall into protection scope of the present invention within.
