Abstract
An accidental braking protection structure for a chain saw comprises a protective cover. A hinge movement lever and a stop spring are mounted in the protective cover, an action end of the hinge movement lever is connected with the stop spring and linked with one end of a hub braking disk stainless steel band, the other end of the hub braking disk stainless steel band is fixed into the protective cover, the hub braking disk stainless steel band is positioned on an outer ring of a clutch hub, and at least three radiating holes are formed in the hub braking disk stainless steel band at intervals. The accidental braking protection structure for the chain saw can effectively eliminate potential safety hazards.
Description
Technical field
The utility model relates to a kind of chain saw, especially a kind of accident roll-over protective structure of stopping.
Background technology
In existing chain saw; brake structure comprises the unexpected roll-over protective structure of stopping; this structure comprises protective cover; hinge movement lever and retaining spring are installed in described protective cover; the motion end of described hinge movement lever is connected with retaining spring; one end interlock that the motion end of described hinge movement lever and hub formula are stopped dish stainless steel band, the stop other end of dish stainless steel band of described hub formula is fixed in described protective cover, and the described hub formula dish stainless steel band of stopping is positioned at the outer ring of clutch hub.When in case of emergency, described hinge movement lever action, the motion end of described hinge movement lever affects fast the hub formula dish stainless steel band of stopping under the effect of described retaining spring, described hub formula is stopped and is coiled the clutch hub that stainless steel band can be held High Rotation Speed fast tightly, now, hub formula is stopped dish stainless steel band because friction easily produces a large amount of heats, and temperature can raise.
After emergency unchaining, described hinge movement lever resets, and the motion end of described hinge movement lever drives the hub formula dish stainless steel band of stopping to unclamp.
The defect of existing existence: the hub formula dish stainless steel band temperature height of stopping is too fast, easily causes skidding, has potential safety hazard.
Summary of the invention
The deficiency that has potential safety hazard of stopping roll-over protective structure in order to overcome the accident of existing chain saw, the utility model provides a kind of accident of the chain saw effectively eliminating safe hidden trouble roll-over protective structure of stopping.
The utility model solves the technical scheme that its technical problem adopts:
A kind of accident of chain saw roll-over protective structure of stopping; comprise protective cover; hinge movement lever and retaining spring are installed in described protective cover; the motion end of described hinge movement lever is connected with retaining spring; one end interlock that the motion end of described hinge movement lever and hub formula are stopped dish stainless steel band; described hub formula stop dish stainless steel band the other end be fixed in described protective cover; described hub formula is stopped and is coiled the outer ring that stainless steel band is positioned at clutch hub, and described hub formula is stopped to coil on stainless steel band and is uniformly-spaced disposed to and lacks 3 louvres.
Preferably, described hub formula stop dish stainless steel band width be 8～15mm, the diameter of described louvre is 1.5～4mm, the interval of adjacent louvre is 6～11mm.
The beneficial effects of the utility model are mainly manifested in: hub formula is stopped and coiled the first-class louvre that is intervally distributed with of stainless steel band, can effectively reduce temperature, improves safety coefficient, eliminates safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is the stop schematic diagram of roll-over protective structure of the accident of chain saw.
Fig. 2 is the stop exploded view of roll-over protective structure of the accident of chain saw.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2; a kind of accident of chain saw roll-over protective structure of stopping; comprise protective cover 1; in described protective cover, 1 installs hinge movement lever 2 and retaining spring 3; the motion end of described hinge movement lever 2 is connected with retaining spring 3; one end interlock that the motion end of described hinge movement lever 2 and hub formula are stopped dish stainless steel band 4; described hub formula stop dish stainless steel band 4 the other end be fixed in described protective cover 1; described hub formula is stopped and is coiled the outer ring that stainless steel band 4 is positioned at clutch hub 5, and described hub formula is stopped to coil on stainless steel band 4 and is uniformly-spaced disposed to and lacks 3 louvres 6.
Preferably, described hub formula stop dish stainless steel band width be 8～15mm, the diameter of described louvre is 1.5～4mm, the interval of adjacent louvre is 6～11mm.Can carry out different size settings as required.
Described louvre 6 along hub formula stop dish stainless steel band length direction uniformly-spaced arrange.
The hub formula of the present embodiment dish stainless steel band of stopping adopts punching to improve radiating effect, accelerates brake ribbon cooling, and the temperature rise coefficient that makes to brake reduces, and has improved stop safe effect, simple in structure, and flexible operation is easy to assembling, and production efficiency is high.
