Abstract
The utility model relates to a movable safety hood for an angular polisher, comprising a fixed semicircular hood fixedly connected with a cutting machine via a frame, which is characterized in that a shaft is fixedly connected at the circle center of the fixed semicircular hood; the hood body of a semicircular movable safety hood larger than the fixed semicircular hood is hinged with the shaft; a handle is arranged on the hood body; a return spring is arranged between the hood body and the fixed semicircular hood; a saw blade of the cutting machine is integrally covered with the movable safety hood and the original fixed hood; when the cutting machine is working, the movable hood is rotated via the handle to expose the saw blade for normal work, while when the cutting machine is slipping out of hand by accident, the movable safety hood is rapidly returned to cover the saw blade under the action of the return spring and protect the safety of workers. The utility model has the advantages of simple structure, high practicability and reliability.
Description
Technical field:
The utility model relates to a kind of activity safety cover of electric angle grinder.
Background technology:
For accelerate empty divide the aluminium vessel group to the processing and the construction speed of process pipe groove, improve cutting accuracy to improve the cleannes in welding quality and the pipeline, use after generally changing the emery wheel of electric angle grinder into sintered carbide circular saw at present.Owing to adopt the sintered carbide circular saw processing aluminum materials, therefore operating efficiency is higher, but simultaneously, because cutting quantity has greatly also strengthened the danger of work, when especially carrying out operation in the place of certain operations inconvenience, electric angle grinder is slipped out of the hand easily, at this moment, the fixed protective cover of original semicircle can't guarantee operator's safety, and the saw blade of rotation can bring personal injury to the operator at a high speed.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of electric angle grinder activity safety cover that can effectively ensure operator's safety being provided.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model comprises fixed semicircle cover, and described fixed semicircle cover is fixed on the cutting machine by framework.
Design feature of the present utility model is at the circle centre position of fixed semicircle cover affixed one, links greater than cover body and this axle of the semicircle activity safety cover of fixed semicircle cover, and cover body is provided with handle, is provided with return spring between cover body and the fixed semicircle cover.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model with activity safety cover and original fixed semicircle cover together, the cover that the saw blade of cutting machine is complete rises, during work, rotate movable guard by handle, with its outside that covers on fixed cover, saw blade exposes operate as normal, when cutting machine is slipped out of the hand because of accident disengaging operator's control, activity safety covers under the effect of return spring, return covers saw blade rapidly, can ensure operator's safety effectively, it is simple in structure, the reliability height.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Number in the figure: 1 fixed semicircle cover, 2 frameworks, 3,4 frameworks, 5 cover bodies, 6 handles, 7 return springs.
The specific embodiment:
Referring to Fig. 1, axle 3 is welded on the framework 2, and cover body 5 is provided with framework 4, and cover body 5 and axle 3 are hinged, are welded with handle 6 on the cover body 5, are provided with return spring 7 between cover body 5 and the fixed semicircle cover 1.Axle 3 length is greater than the diameter of return spring 7, and cover body 5 is when rotating to certain angle, and return spring 7 draws back around axle 3, guarantees the force direction that is subjected to of cover body 5, make its can be when accident rapid return.Framework 2 and framework 4 constitute for band iron, to save the space.
During off working state; cover body 5 and fixed semicircle cover 1 are a complete circular safety guard, saw blade are covered on wherein, during work; by handle 6 rotation cover bodies 5; the saw blade that exposes cutting machine, the finger of a hand of operator is held cutting machine and handle 6 simultaneously, when the appearance accident, when cutting machine is slipped out of the hand; cover body 5 is under the effect of return spring 7; rapid return, the saw blade that will expose covers, and the protection workman escapes injury.
