Abstract
An electric chain saw brake apparatus comprises an electric chain saw body case, with a changeover speed gear body arranged in the body case. An inner gear is provided with a groove, a clutch slug corresponding to the groove is arranged in a clutch rotary table which is provided with supporting feet and arranged in the changeover speed gear body through the supporting feet, with inclined tables arranged on the lower portions of the supporting feet. Concave gaps corresponding to the inclined tables are arranged at corresponding positions of the changeover speed gear body and the supporting feet. A clutch button is connected with a push bar which is connected with a push block, and the other end of the push block is connected with a racking plate and a connecting bar which is connected with the clutch rotary table. After utilizing the brake apparatus of the utility model, accidents of the electric chain saw can be greatly reduced. A protection plate is arranged outside the electric chain saw body case, and the protection plate is connected with the push block through a poking block. When in emergency, the protection plate is pushed to make a saw chain drive pulley separate with the motor, thereby avoiding accidents and protecting the electric chain saw.
Description
Technical field:
The utility model relates to the electric chain saw technical field, particularly a kind of electric chain saw brake gear.
Background technology:
At present, people often use the electric chain saw of high speed rotating to carry out sawing work.Existing electric chain saw generally only adopts switch to control the work of electric chain saw, occurs easily bringing contingency because of improper use to the operator.Moreover when electric chain saw ran into more difficult sawing thing, the sawing thing can compress saw chain, and saw chain can't be rotated, and causes burn-down of electric motor, thereby damaged electric chain saw.
Summary of the invention:
At above deficiency, the inventor has proposed a kind of electric chain saw brake gear that is beneficial to protection electric chain saw and operator.It comprises: be provided with gearbox body in electric chain saw casing, the casing; Be provided with machine shaft gear and internal gear in the gearbox body; It is characterized in that: internal gear is provided with groove, be located in the clutch rotating disk with the corresponding clutch motion block of this groove, the clutch rotating disk has feet and is placed on the gearbox body by feet, and the feet bottom is provided with sloping platform, and gearbox body and feet corresponding position are provided with and the corresponding notch of sloping platform; Brake gear is provided with the clutch button of band stage clip, and the clutch button is connected with push rod, and push rod links to each other with pushing block, and the pushing block other end is connected with rocker and connecting rod, and connecting rod links to each other with the clutch rotating disk.
The course of work of the present utility model is as follows: during work, promote the clutch button earlier, the clutch button drives push rod, and push rod drives pushing block, the pushing block drivening rod, connecting rod drives the clutch rotating disk, and the sloping platform of the feet bottom of clutch rotating disk is entered in the notch on the gearbox body, at this moment, the Push switch button, after motor was connected, motor power was sent a telegraph the driving wheel and the saw chain of chain saw by the transmission of clutch motion block after internal gear slows down.In case of emergency, unclamp the clutch button, the sloping platform of clutch carousel supports underfooting portion just breaks away from the notch on the gearbox body, makes the groove on the clutch motion block disengaging internal gear, thereby the driving wheel of saw chain is run out of steam.Electric chain saw can reduce the generation of contingency greatly after using brake gear of the present utility model.
In the utility model, described electric chain saw housing is provided with protective plate outward, and protective plate links to each other with pushing block by shifting block.Because protective plate links to each other with pushing block by shifting block, in case of emergency, promote protective plate, protective plate drives pushing block and connecting rod, makes the sloping platform of clutch carousel supports underfooting portion break away from notch on the gearbox body, thereby makes the groove on the clutch motion block disengaging internal gear.Make the saw chain driving wheel throw off motor, prevent unexpected the generation.When electric chain saw runs into more difficult sawing thing and kills saw chain, promote protective plate, motor breaks away from saw chain and dallies, and can prevent burn-down of electric motor, thus the protection electric chain saw.
In the utility model, described clutch button below is provided with the extension, and shift knob is provided with and corresponding blocking part, this extension.Adopt this kind structure, can prevent to produce maloperation.
