Description
Technical field
The utility model relates to a kind of electric tool, especially relates to a kind of damping electric hammer.
Background technology
Suitable big of traditional electric hammer handle part vibrations in use, the vibrations conference causes user's work fatigue, body and mind suffers damage, the damping device that has occurred a kind of electric hammer at present, as China Patent No. is 200710069632.3 " the electric hammer handle for tool with damping ", pair of permanent magnets is housed respectively between two boom ends of housing afterbody two inboard aperture of electric hammer and " C " shape electric hammer handle constitutes repulsion type magnet spring, and this magnet spring processing difficulties, manufacturing cost is big.In addition, this structure is buffering with the magnet spring, and structure is simple inadequately.
The utility model content
The purpose of this utility model is at above deficiency, provides a kind of cheap for manufacturing cost, simple in structure, easy to operate, the damping electric hammer of good damping effect.
The technical solution adopted in the utility model: damping electric hammer, comprise main case, gear-box and handle, be respectively equipped with damping device I, II between described handle and gear-box and the main case, described damping device I comprises last rubber sleeve that is fixed between handle and the gear-box and the damper I that places in rubber sleeve and the handle, described damper I comprises fixed metal frame I and the live metal frame I that is fixed on the handle, described fixed metal frame I connects with live metal frame I by yielding rubber, and described live metal frame I is fixed on the gear-box; Described damping device II comprises following rubber sleeve that is fixed between handle and the main case and the damper II that places down in rubber sleeve and the handle, described damper II comprises fixed metal frame II and the live metal frame II that is fixed on the handle, described fixed metal frame II connects with live metal frame II by yielding rubber, described live metal frame II is fixed on the main case, is respectively equipped with cushion chamber I, II between described live metal frame I top and the fixed metal frame I and between live metal frame II top and the fixed metal frame II.
Further, described fixed metal frame I and fixed metal frame II are fixed on the handle by hold-down screw, described live metal frame I and live metal frame II be separately fixed on the gear-box by hold-down screw and main case on.
Damping device I of the present utility model, II are respectively equipped with damper I, II, described damper I comprises fixed metal frame I and the live metal frame I that is fixed on the handle, described fixed metal frame I connects with live metal frame I by yielding rubber, and described live metal frame I is fixed on the gear-box; Described damper II is fixed on fixed metal frame II and the live metal frame II on the handle, and described fixed metal frame II connects with live metal frame II by yielding rubber, and described live metal frame II is fixed on the main case.This structure adopts the yielding rubber between fixed metal frame and the live metal frame to connect as buffering, regulates the motion of live metal frame with the intrinsic elasticity of yielding rubber, reaches the purpose of damping, reduces the vibrations of the handle of electric hammer instrument.In addition, be respectively equipped with cushion chamber I, II between live metal frame I top and the fixed metal frame I and between live metal frame II top and the fixed metal frame II, like this when the vibration amplitude of electric hammer is big, the motion of live metal frame I, II can reach the purpose of abundant damping, the vibrations that alleviate handle part further respectively by the adjusting of cushion chamber I, II.
The utility model adopts said structure, the vibrations that electric hammer produced, and under the effect of damper I, II, the vibrations of handle part obviously reduce, and the user can not feel well because of huge vibrations in use, even the injury health.
The utility model has the advantages that: cheap for manufacturing cost, simple in structure, easy to operate, good damping effect.
