Abstract
The invention discloses a brake braking device of an oil saw. The brake braking device comprises a brake bracket, a hand protecting device, a spring, a cam, a brake reed combination and a driven disc, wherein the brake reed combination is provided with a brake reed and a guide column; the guide column is sleeved with the spring. The brake braking device is characterized in that one end of the driven disc is sleeved with the brake reed, one end of the bake reed is fixedly arranged on the brake bracket, and the other end of the brake reed is fixedly arranged on the guide column; the end part of the guide column is contacted with the cam all the time under the effect of the spring; when the hand protecting device is rotated, the cam is driven to rotate and the guide column stretches frontwards when the spring extends along with the rotation of the cam, so as to drive the brake reed to tightly hold the driven disc to realize a braking function. The hand protecting device is a double-arm hand protecting device; with the adoption of the structure, the operation is convenient in a braking process and the reliability is high; the service life of a braking part can be prolonged effectively. The braking part is simple in structure, convenient to detach and high in reliability; the safety of the braking part and even the oil saw, can be improved effectively.
Description
Technical field
The present invention relates to chain saw technical field, particularly the braking device of chain saw.
Background technique
Chain saw owing to thering is compact structure, volume is little, quality is light, running speed-raising is fast etc., and advantage is widely used in the arbors in place such as family, gardens, road, forest, the cleaning of trees, producing material, forest is removed obstacles and isolates the operation fields such as fire belt.The brake part of chain saw is safety component, it is more common that domestic market brake part is joined single armed hand protector mainly with connecting rod, and the major defect of this structure is that connecting rod component are many, linking mechanism more complicated, requirement to component precision and assembling is higher, poor reliability, dismounting is inconvenient especially, and the single armed hand protector relatively effort that operates, firmly concentrate, easily damage machine, cause working life short, cost is high.Therefore, be badly in need of a kind of simple in structure, easy accessibility, reliability high, operate the brake part comfortable, cost is low.
Summary of the invention
The braking device that the object of this invention is to provide a kind of chain saw, this structure is comprised of braking bracket, cam, spring, brake spring combination, the hand protector of remote holder handle meets accident bounce-back during to operator at guide plate, effect bottom left the back of the hand at inertia will push away before hand protector, the rotation band moving cam of hand protector rotates, constantly protract under the elastic reaction of spring with the brake reed of cam close contact, hold driven disc tightly braking gradually, thereby play the effect of brake.
The technological scheme that the present invention takes is:
A kind of braking device of chain saw, by braking bracket, hand protector, spring, cam, brake spring combination, driven disc, formed, described brake spring combination is provided with brake reed, guide pillar, and described spring housing is contained on guide pillar, and is placed in the guiding groove being formed by described braking bracket; It is characterized in that: described cam, hand protector are all rotatably installed on machine, and the rotational band moving cam of hand protector rotates; After described brake reed is sleeved on driven disc, one end is fixed on braking bracket, the other end is packed on guide pillar, under the effect of spring, the end of guide pillar contacts with cam all the time, when rotating hand protector, along with the rotation guide pillar of cam stretches and protracts with spring, thereby pull brake reed to hold driven disc tightly, realize brake function.
Described hand protector is both arms hand protector.
The invention has the beneficial effects as follows, thereby the brake part that adopts this technological scheme to make is simple in structure, easy accessibility, reliability are high, operate and comfortable, laborsavingly extend its working life, can effectively improves the Security of brake part and even chain saw.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, chain saw braking device of the present invention, is comprised of braking bracket 3, both arms hand protector 8, spring 11, cam 1, brake spring combination (brake reed 10, guide pillar 9, baffle plate 17, pin-and-hole 18), driven disc 6.
Baffle plate 17 is fixed on guide pillar 9, spring 11 is sleeved on guide pillar 9 and is positioned at a side of baffle plate 17, guide pillar 9 is placed in the guiding groove 12 being formed by braking bracket 3, after brake reed 10 is enclosed within on driven disc 6, one end is packed on guide pillar 9, the other end is hooked on the straight pin 14 that is fixed on braking bracket 3, backing pin 13 is inserted in pin-and-hole 18, by spring bumper cover 7 and protective block 5, is arranged on braking bracket 3 with fixing brake spring combination, and driven disc 6 is arranged on the output shaft of petrol engine 16.
Both arms hand protector 8 is arranged on petrol engine 16 by screw 15, and cam 1 is rotatably installed on bearing pin 2, and bearing pin 2 is fixed on braking bracket 3, and braking bracket 3 is arranged on petrol engine 16.
Chain saw when operation when guide plate meets accident bounce-back during to operator, effect bottom left the back of the hand at inertia will push away before both arms hand protector, the rotation band moving cam of both arms hand protector rotates, rotation along with cam, constantly protract under the elastic reaction of spring with the guide pillar of cam close contact, drive brake reed to hold driven disc tightly braking gradually, thereby play the effect of brake.
The invention has the beneficial effects as follows, thereby the brake part that adopts this technological scheme to make is simple in structure, easy accessibility, reliability are high, operate and comfortable, laborsavingly extend its working life, can effectively improves the Security of brake part and even chain saw.
