Abstract

The invention discloses a garden tool used rotating axial direction brake device that is made up of working shaft, driven wheel, casing and brake block. The working shaft connects rotating connects to the casing, and the brake block is set on the casing. The working shaft screw connects to driven wheel. Bulges are set on the out surface of the driven wheel. Moving component is fixed on working shaft. When the power for the invention is cut, inertia difference is existed between working shaft and the rotators installed on the working shaft to the driven wheel, and causes relatively rotating between working shaft and driven wheel. Then, the driven shaft would move to the axial direction until contacting to the brake block. Thus, the requirement for the material quality would be declined. And it is simple structure and is easy to machined and maintained.

Description

Inertial rotation axial braking device for gardening tool
Technical field
The present invention relates to a kind of braking device that is used for garden instrument, relate in particular to a kind of inertial rotation axial braking device for gardening tool.
Background technique
Garden instrument is after power source is cut off, and its working shaft can not stop very soon owing to inertia.But the device that has some that specific (special) requirements is arranged is required after power source is cut off, and its revolving part that is installed on the working shaft can stop operating fast.The grass pruning machine that for example belongs to the gardens electric tool, revolving part is blade, by belt transmission, require blade to stop operating in 3～5 seconds behind the supply disconnecton of motor between working shaft and the motor main shaft, present above-mentioned garden instrument is put and is all adopted some devices to help fast braking.Wherein have and take the deceleration of electrons device, in case but electronic component lost efficacy, " killing " phenomenon will take place, cause motor to damage.Have and adopt mechanical brake equipment, but the structure of present disclosed mechanical brake equipment is all complicated, poor reliability, processing, maintenance owe convenient.Other axial brake shortcoming is: 1, manufacturing structure complexity, manufacture cost height; 2, owing to utilized the elastic force of spring to come braking brake, As time goes on spring force can diminish, and loses efficacy at last.
Summary of the invention
The invention provides a kind of can reduce material requirements to component, simple in structure, reliability is high and reach the inertial rotation axial braking device for gardening tool of standard-required.
The present invention adopts following technological scheme:
A kind of inertial rotation axial braking device for gardening tool, form by the working shaft that is used for mounting cutter, follower, shell and brake slipper, the working shaft and the shell of mounting cutter are rotationally connected, brake slipper is located on the shell, working shaft is threaded with follower, on the exterior edge face of follower, be provided with projection, on working shaft, be fixed with dialing part and be arranged on the position that the rotational plane that can make dialing part is positioned at the altitude range of projection.
Compared with prior art, the present invention has following advantage:
1. after power source is cut off, working shaft and be installed on revolving part (cutter etc.) on the working shaft and follower between the inertia that exists poor, working shaft and follower are relatively rotated, follower is moved axially, touch and act on the brake slipper that is installed on the shell until the follower inner side end, produce the braking friction, therefore the positive pressure that produces the braking friction realizes by screw thread, compared with prior art, the producing method of the required positive pressure of this friction can reduce the material requirement to related components, thereby reduce cost, simple in structure, the braking reliability is high and reach standard-required, processes, easy to maintenance; When electric motor starting, follower begins to rotate, and relatively rotates with the working shaft that is in static inertial states, makes the follower inner side end break away from brake slipper, and instrument is in running order.
2. the brake slipper of forming by untie-sell, position-limitting pin, spring and untie-sell seat, when braking takes place, because the effect of spring makes brake slipper be adjacent to follower all the time, keep good braking effect and reliability, and can effectively overcome because of the uneven defective that reduces braking effect of braking surface.
3. the technical measures of friction plate are set on follower, have increased reliability, prolonged working life, simplified processing technology, reduced cost and do not reduced braking effect.Friction plate is simple in structure, is easy to processing, combines with follower, and it is durable, wear-resisting that it is become, and can reduce processing request again, meet the follower of brake request.
4. the whole projection of adjustable positions can make projection be positioned at rational position.
