Abstract

The utility model relates to a hand-held electric polishing machine, which comprises an electric motor, a grinding disc and three cross bars with one end fixedly connected with the electric motor. Support legs are connected to the cross bars. The hand-held electric polishing machine is characterized in that the upper end of a motor shaft is provided with a plurality of blades, the excircle of the blades is provided with a protection circle, and when the electric polishing machine is operated, because the blades mounted at the upper end of the electric motor generate centrifugal force to reduce the weight of the electric motor, operators can conveniently operate while saving labor. In addition, a plurality of blades are mounted on the grinding disc, which can further reduce dust diffusing around, thereby favoring for the sanitation of workers and guaranteeing a clean environment.

Description

The hand held, electric sanding machine

One, technical field

The utility model relates to a kind of sanding machine, especially a kind of hand held, electric sanding machine.

Two, background technology

Tradition adopts manual rubber sand milling to the polishing (putting down) of wall, ceiling etc., occur in recent years polishing with the polishing one usefulness electric polishing machine of mechanical system, this kind sanding machine comprises motor, at the fixing mill of the rotating shaft end of motor, is fixed with abrasive materials such as rubber on mill.This kind sanding machine in use exists: the one, when work only with hand feel to control flatness, so often owing to exerting oneself the irregular out-of-flatness that causes institute's flour milling; The 2nd, the dust that produces during work can influence working environment.I am once at patent application hand held, electric sanding machine in 2003, application number is 03201863.0, though overcome with feel because the inhomogeneous out-of-flatness that causes institute's flour milling of exerting oneself, the dust that produces influences environmental pollution to be reduced, but when operation, because motor etc. are bigger from weight, operation is gruelling when work, and when work dust to around extension big, still can influence environmental pollution.

Three, summary of the invention

Laborsaving, easy to use when problem to be solved in the utility model provides a kind of operation, as can not cause dust to fly upward when controlling grinding face flatness and work easily hand held, electric sanding machine.For addressing the above problem, the utility model has adopted following technical scheme: it comprises motor 1, be connected in the mill 3 on the output shaft 2 of motor, and the cross bar 4 that is connected of three or more ends and motor, cross bar 4 also is connected with leg 5, leg 5 is movably with cross bar 4 tie points, be that leg 5 is scalable being connected on the cross bar 4, it is characterized in that being provided with three or more fan blades 14, during the fan blade rotation in the upper end of motor shaft 2, alleviate from weight, make rapid operation; Cylindrical at fan blade is equipped with fan blade guard circle 13, for reduce dust to around diffusion, on mill 3, be provided with 3 or a plurality of fan blade 14 ', also be equipped with dust cover on the end face that each cross bar returns and on the side face that surrounds of each leg.

Owing to adopted technique scheme, one side at least 3 adjustable legs on sanding machine, can control mill on same level, avoided because firmly the not section of the uneven frosted dirt bevel that causes is whole, on the other hand owing to be provided with three or more fan blades 14 in the upper end of motor shaft 2, when fan blade rotates, can alleviate from weight, make rapid operation, more convenient; On mill, be provided with again a plurality of fan blades 14 ', when mill is worked, can reduce dust to diffusion all around, simultaneously owing on end face and side face, be provided with dust cover, dust in the time of can further preventing sanding machine work flies upward, and helps clean environment and staff's health.

Four, description of drawings

Fig. 1 is the structural representation of hand held, electric sanding machine of the present utility model;

Fig. 2 is the shape assumption diagram of hand held, electric sanding machine of the present utility model;

Among Fig. 1, Fig. 2,1, motor; 2, motor shaft; 3, mill; 4, cross bar; 5, leg; 6, handle; 7, end face dust cover; 8, side face dust cover; 9, paste pin; 10, fixed block; 11, scale; 12, dust excluding plate; 13, fan blade protective cover; 14, fan blade; 14 ', fan blade; 15 paste sole.

Five, the specific embodiment

Embodiment: as shown in Figure 1 and Figure 2; hand held, electric sanding machine of the present utility model comprises motor 1; on motor 1, be equipped with handle 6; be connected in the mill 3 on the motor shaft 2 of motor 1; mill 3 is equipped with a plurality of fan blades 14 ' and fixedly rubber and abrasive material, and three or three above fan blades 14 are housed in the upper end of motor shaft 2, at the cylindrical of fan blade fan blade guard circle 13 is housed; three or more the cross bars 4 that are connected are as four, five.Present embodiment is an example with three cross bars 4, be connected with leg 5 on described each cross bar 4, leg 5 has certain angle with cross bar 4, angle shown in Fig. 1 is 90 °, the tie point that is connected with cross bar 4 on leg 5 is movably, and promptly leg 5 is scalable being connected on the cross bar 4, also can be provided with scale 11 on each leg 5, its objective is and when the telescopic adjustment leg, can directly learn flexible length.Be equipped with dust cover 7 on the end face that each cross bar 4 surrounds, the dust cover 7 the most handy plastic plates on the described end face are made, can certainly be with other materials such as metals; On the side face that each leg 5 surrounds dust cover 8 is arranged also, the dust cover 8 on the described side face the most soft material such as handy cloth is made.When the utility model portable electric sanding machine is worked because three fan blades 14 are housed in the upper end of motor shaft 2, during rotation under action of centrifugal force, alleviated sanding machine from weight, bring laborsaving, convenient to operating personnel; Again since be equipped with on the mill a plurality of fan blades 14 ', when mill rotate, under the effect of centripetal force, stop dust to around spread, further reach and help environment and staff's sanitation and hygiene.

From the foregoing description, can draw, during sanding machine of the present utility model work because the motor shaft upper end is provided with three or more fan blade, the centrifugal force of generation, alleviate sanding machine from weight, it is more laborsaving, convenient that the operative employee is operated.Clean environment when mill is provided with dust cover on a plurality of fan blades and end face, the side face and helps work and staff's health.
