Abstract
The utility model discloses an anti-rotation structure and particularly relates to an anti-rotation structure for a rivet of a chain saw guide plate. Chain saws are widely applied to operations of forest lumbering, young tree protection, lumber yard bucking, wood processing and cutting, garden trimming and the like. The anti-rotation structure comprises two outer guide plates and an inner guide plate, the inner guide plate is arranged between the outer guide plates, the tail ends of the outer guide plates are fixed through the rivet, a chain saw chain wheel is sleeved outside the rivet, rollers which are uniformly distributed are arranged between the chain saw chain wheel and the rivet, and a chain wheel inner ring is arranged between the rollers and the rivet. The anti-rotation structure for the rivet of the chain saw guide plate is compact in structure and capable of improving using performances, prolonging the service life and reducing using costs.
Description
Technical field
The utility model is a kind of anti-rotation structure, the particularly anti-rotation structure of a kind of chain saw guide plate rivet, and chain saw is widely used in the forest lumbering, and young growth is protected and educates, the timber depot producing material, timber processing cuts the operations such as material and gardens trimming.
Background technology
That all kinds of saw chain guide plate of the prior art divides is stacked, three kinds of head-changeable and monoblock types, and stacked and head-changeable guide plate is used for timber processing and cuts the operations such as material and gardens trimming.Owing to saw chain high load capacity during sawing, run up, guide plate head sprocket wheel bearing capacity is larger, and the rivet of riveted joint place is loosening and follow sprocket rotation easily, causes premature wear, becomes the rapid wear product of unrepairable.The saw chain guide plate is low service life, and saw chain guide plate price is very high, frequent saw chain guide plate not only directly increases production cost, seriously reduced the cutting-rate of chain saw, also be a kind of very large wasting of resources to chain saw, caused very large economic loss, the chain saw that causes present China to produce is exactly of low quality, the market competitiveness is not strong, far can not satisfy the forest zone to the wilderness demand of chain saw.Therefore, the saw chain guide plate is one of system key factor of pressing down chain saw production efficiency and production cost service life.
Chinese patent 200410103156.9 discloses a kind of strainer of rate of tension of the saw chain for regulating chain saw.Rotatable knob is worked with engine underframe, clutch cap and guide plate, thus, this knob can rotate between restraint location and released position, at this restraint location, this guide plate is fastened between engine underframe and the clutch cap, and in this released position, this guide plate unclamps and can regulate.When joystick knob is in latched position, at least one engagement point and corresponding fixed engagement point gearing, and engagement point that should be remaining not with the fixed engagement point gearing, and when joystick knob is in non-locked position, this engagement point and the disengaging of this fixed engagement point are meshed.This structure relative complex, and cutting-rate is low, and service life is low.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact conformation, and satisfying the chain saw guide plate under high speed wearing and tearing, impact and complex stress effect, low cost, high efficiency, long-life requirement are satisfied forestry to the anti-rotation structure of saw chain guide plate rivet of the demand of chain saw.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The anti-rotation structure of a kind of chain saw guide plate rivet, comprise two outer guide plates and inner guide plate, be provided with inner guide plate between described outer guide plate, fix by rivet between the afterbody of described outer guide plate, described rivet overcoat has the chain saw sprocket wheel, be provided with equally distributed roller between described chain saw sprocket wheel and rivet, be provided with the sprocket wheel inner ring between described roller and rivet.
As preferably, the head both sides of described inner guide plate are provided with the inner groovy of a pair of symmetrical distribution, and described inner groovy is by head rivet and the clamping of outer guide plate phase.
As preferably, the number of teeth of described chain saw sprocket wheel is 7～12, and the head of described outer guide plate is provided with the pilot hole of strip, is provided with equally distributed subtracting in the described inner guide plate and joins groove, describedly subtracts that to join groove be strip hole or circular port.
As preferably, described head rivet is located in the rivet hole, and the inwall of described rivet hole is provided with more than one rivet fixed bit.
Existing special-shaped rivet hole is applied on the saw chain guide plate of chain saw, reaches the non-rotary performance requirement of rivet after cooperating corresponding rivet, improves the performances such as shock resistance, and Service life has arrived more than 5 times of former common lumbering saw chain guide plate.Expense reduces, and the sawing operating efficiency improves.
Therefore, the anti-rotation structure of a kind of chain saw guide plate rivet that the utility model provides, compact conformation improves serviceability, increases the service life, and reduces use cost.
