Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of chain saw of the present invention is described in further detail:
As shown in embodiment in Fig. 1～2, this is a chain link of the present invention, comprises sawtooth 1, chain sheet 2, and this sawtooth 1 and chain sheet 2 are by the sheet metal of a slice strip, as steel disc is stamped to form.
Chain sheet 2 is provided with the waist 3 narrower than two ends, and waist 3 is provided with kink 4, and kink 4 makes a chain sheet 2 form two lateral plates 5, becomes double-decker.
Kink 4 is integrative-structure with lateral plate 5, in dragsaw process, is difficult for getting loose, and except non-metal plate fracture, this,, for manual dragsaw operation, has good mechanical strength.Sawtooth 1 is arranged on lateral plate 5 edges, and lateral plate 5 is provided with side opening 6, and side opening 6 can allow lateral plate 5 pass, and waist 3 can rotate in side opening 6.When assembling, can, by one of them chain sheet 2, as shown in fig. 1, be bent into a chain link, as shown in Figure 2.Then the side opening 6 one of them lateral plate 5 of another chain sheet 2 being passed on this chain link, as shown in Figure 3, afterwards, by another chain sheet 2 90-degree rotation in side opening 6, as shown in Figure 4, then bends, and forms second chain link.By that analogy, just several chain links can be linked together successively one by one.Every two adjacent chain links are hooked together by kink 4 and the edge of side opening 6.Because waist 3 is narrower than lateral plate 5, the therefore space for providing through hole is set on lateral plate 5.Like this, as long as side opening 6 width on lateral plate 5 are greater than the width of kink 4, kink 4 just can hang in the forward edge of side opening 6.
In side opening 6, be provided with a circular hole 7, circular hole 7 sides are provided with the longitudinal slotted eye 8 extending to kink 4, that is to say that this side opening 6 is made up of a circular hole 7 and a longitudinal slotted eye 8.Because the length of kink 4 is fixed, in the time that kink 4 is in circular hole 7, can leans against circular hole 7 sides and slide, make can convert equably bending angle between two chain links.
And longitudinal slotted eye 8 on circular hole 7 limits is lengthened the length of side opening 6, large than the diameter of circular hole 7, can allow a part for lateral plate 5 pass through from circular hole 7, another part passes through from longitudinal slotted eye 8.Like this, under the certain condition of chain sheet 2 sizes, can reduce the area of side opening 6 as far as possible, naturally also just strengthen the area of lateral plate 5 entity part, the mechanical strength of chain link is strengthened.
Sawtooth 1 is arranged on the edge of one of them lateral plate 5.Sawtooth 1 is on the edge of lateral plate 5, and the width of lateral plate 5 can increase naturally.When sawtooth 1 being all arranged on the edge of one of them lateral plate 5, on the edge of another lateral plate 5 without sawtooth, like this, the serrate lateral plate 5 of ratio that the width of another lateral plate 5 can design is naturally narrow, another lateral plate 5 can be passed from side opening 6, now longitudinally the depth dimensions of slotted eye 8 also can reduce, and the area of side opening 6 is further reduced, the area of nature lateral plate 5 entity part further strengthens, and the mechanical strength of chain link is strengthened again.
Circular hole 7 slightly larger in diameter are in the width of kink 4.The state that the area of side opening 6 can penetrate at lateral plate 5 is like this issued to minimum, and this is also to make the area of side opening 6 as far as possible little, and the area of lateral plate 5 entity part is further strengthened.Longitudinally the thickness of slotted eye 8 is greater than the thickness for sheet metal, just can allow a strip sheet metal through being advisable.Therefore, the width of side opening 6 is determined by the width of kink 4, can be affiliated in side opening 6 and be as the criterion with kink 4.The length of side opening 6 equals the degree of depth that circular hole 7 diameters add longitudinal slotted eye 8, is determined by the width of lateral plate 5.Can reduce like this transverse width of circular side opening 6, make the slightly larger in diameter of side opening 6 in the width of kink 4, thus make that the transverse width of strip sheet metal can manufacture wide as far as possible, to strengthen the mechanical strength of chain link.
Sawtooth 1 is arranged on the edge of one of them lateral plate 5.On another lateral plate 5, can not establish sawtooth 1 like this, make another lateral plate 5 width the narrowest, cause longitudinal slotted eye 8 can do minimumly, as far as possible compared with the area in hole on chainlet sheet 2, thereby the mechanical strength that strengthens chain sheet 2, the mechanical strength of natural chain link is also strengthened.
The sawtooth 1 being arranged on each lateral plate 5 edges has at least one vertically to hold up and a perk laterally, and the height of perk is greater than the thickness of lateral plate 5.Because the thickness of two chain link junctions adjacent has the thickness of at least four layers of sheet metal, therefore the sawtooth 1 on lateral plate 5 edges at least will cut the thickness of two sheet metals, the sawtooth 1 of vertically holding up is sawed out the saw kerf of himself thickness, the sawtooth 1 of perk is laterally sawed out the thickness saw kerf of a lateral plate 5, like this, sawtooth 1 on two lateral plates 5 just can be sawed out the saw kerf more than thickness that width is four layers of sheet metal, so just can allow whole piece saw blade do not blocked by saw kerf.
On lateral plate 5, be bent with a ledge structure 9, ledge structure 9 makes lateral plate 5 be divided into coxopleure 10 and epimeron 11, and 5 two coxopleures 10 of lateral plate are close together, the thickness that the space between two epimerons 11 can accommodating two lateral plates 5.Ledge structure 9 makes a lateral plate 5 form the thickness of two sheet metals, thereby ensure each link configuration compactness, between two lateral plates 5, space reduces as much as possible, and sticks together as much as possible, prevents from that sawdust from falling into space between two lateral plates 5 and lateral plate 5 being strutted and affect to cut saw.
Sawtooth 1 is arranged on coxopleure 10.To ensure that sawtooth 1 is to start to cut saw from center line one side in the time cutting saw, avoid being cut object centre and cut and form a lamella wedge between two lateral plates 5.
As shown in Figure 5, this is a kind of chain saw with above-mentioned chain link, comprise chain link 12, chain link 12 is provided with sawtooth 1, chain sheet 2, chain sheet 2 is provided with the waist 3 narrower than two ends, waist 3 is provided with kink 4, kink 4 makes chain sheet 2 form two lateral plates 5, and kink 4 is integrative-structure with lateral plate 5, and sawtooth 1 is arranged on lateral plate 5 edges, lateral plate 5 is provided with side opening 6, side opening 6 can allow lateral plate 5 pass, and in two adjacent chain links 12, a kink 4 of a chain link 12 hangs in the side opening 6 of another chain link 12.
