Detailed description of the invention
As shown in Figures 1 to 7, a kind of safety protection structure of electric tool, comprise the protective cover 3 be installed on bearing block 1, the flange 11 that described bearing block 1 comprises pedestal 10 and circumference is arranged outside pedestal one end, the anchor ear 2 that described protective cover 3 comprises cover body and is connected with cover body, described anchor ear is installed on pedestal, and wherein said cover body is linked together by welding and anchor ear.
Described anchor ear is provided with fracture 20, lug has been arranged side by side in anchor ear fracture both sides, connected by connecting bolt 21 between the lug of both sides, described connecting bolt one end passes side lug and the nut 212 that is threaded, the described connecting bolt other end passes opposite side lug and connects a trigger 22, described trigger is provided with endoporus, to be enclosed within outside described trigger endoporus on connecting bolt and to drive connecting bolt to rotate, spring 23 is provided with between described trigger and connecting bolt, spring adopts stage clip, and spring power acts axially on connecting bolt.Described trigger endoporus one end is provided with internal spline 221, and described connecting bolt is provided with outer-hexagonal flange 211, and described internal spline overcoat is outside in hexagonal flange.Described trigger endoporus other end oral area is provided with pad 24, and the outer end of connecting bolt passes from pad, and the outer end of described connecting bolt is connected with back-up ring 25.Described pedestal outer wall is circumferentially provided with axial limiting groove 12, and described anchor ear inwall is provided with banking pin 26, and described banking pin and axial limiting slot fit limit anchor ear along bearing block axial float.Described pedestal end face periphery is circumferentially provided with the installing port 13 corresponding with banking pin.
When protective cover 3 is installed, banking pin 26 puts into bearing block outer ring after aliging with bearing block 1 installing port 13, rotate protective cover 3 and realize axial limiting by banking pin 26, trigger endoporus is provided with internal spline 221 and is set on the outer-hexagonal flange 211 of connecting bolt 21, rotating trigger 22 drives connecting bolt 21 rotating clip to hug hoop 2, prevents protective cover 3 from rotating by the elastic force between anchor ear 2 and bearing block 1, frictional force.
Trigger 22 can move axially along connecting bolt 21, by stage clip, pad 24, back-up ring 25, trigger 22 internal spline 221 is anchored on connecting bolt 2 outer-hexagonal flange 211, when trigger 22 to move along the stage clip direction of connecting bolt 2 axis and compression press spring time, internal spline 221 and outer-hexagonal flange 211 can be made to thread off, rotate trigger 22 to interfere to other arbitrarily angled avoiding with emery wheel, bearing block, move to correct position during operation, rotate trigger 22, anchor ear 2 can realize loosening, tighten protective cover freely; During dismounting protective cover, rotate trigger 22, unclamp anchor ear 2, rotate protective cover and protective cover banking pin 26 is alignd with bearing block 1 installing port 13 and applies axial force and can pull down protective cover.
