Description
The utility model is relevant with abrasive machine, particularly about a kind of front protection cover of electric plane abrasive machine.
The electric plane abrasive machine of usefulness includes: a housing; One motor is located in the housing; One emery wheel is circular plate type, is hubbed on housing front end below, is subjected to turning of motor; One rear shield omits semicircular in shape, and the bottom surface is empty thoroughly, is located at the housing below, is positioned at the top rear side of emery wheel.The user hands housing, carries out grinding work with the emery wheel that protrudes out in rear shield the place ahead, and this rear shield has chip or the spark that backward splashes when blocking grinding, with protection user's effect.Therefore aforementioned structure does not have any shield in the real grinding part desire of emery wheel, is still spark when using and scatters and splash the poor effect of its guard shield.
Main purpose of the present utility model is to provide a kind of front protection cover of electric plane abrasive machine, and it can envelope emery wheel jointly with rear shield, and does not influence grinding operation, and the chip spark that can effectively reduce when grinding splashes.
For reaching above-mentioned purpose, technical characterictic of the present utility model is more to provide a front protection cover that can up start in rear shield the place ahead with electronic flat-faced wheel machine, make forward and backward two guard shields can envelope emery wheel end face and periphery jointly, spark or chip splash everywhere in the time of can preventing abrasion wheel grinding, and can not influence grinding operation.
Now cooperate graphic being described as follows for three embodiment:
Fig. 1 is the three-dimensional exploded view of the utility model first embodiment.
Fig. 2 is the combination stereogram of Fig. 1.
Fig. 3 is the use schematic diagram of first embodiment.
Fig. 4 is the local amplification view along 4-4 hatching line among Fig. 1.
Fig. 5 is the action schematic diagram of front protection cover engaging location.
Fig. 6 is the combination stereogram of the utility model second embodiment.
Fig. 7 is the use schematic diagram of the utility model second embodiment.
Fig. 8 is this exploded perspective view of implementing novel the 3rd embodiment.
At first see also Fig. 1 to shown in Figure 3, the electric plane abrasive machine of the utility model first embodiment includes:
One housing 10 slightly is microscler hollow housing.
One motor (not shown) is contained in this housing 10.
One emery wheel 20, rounded, be hubbed on housing 10 front ends below, be subjected to turning of motor.
One rear shield 30 omits semicircular in shape, and the bottom surface is empty thoroughly, is fixedly arranged on housing 10 belows, is positioned at the top rear side of emery wheel 20, the chip spark that backward splashes when grinding in order to shield.
Above-mentioned is known generally, and characteristics of the present utility model are:
These rear shield 30 dual-sides are respectively established a guide channel 31, two guide channels 31 the inners and are respectively established a pivoted hole 32.
One front protection cover 40, omit semicircular in shape, the bottom surface is empty thoroughly, and an elastic fastening plate 41 is respectively extended in both sides, the coaxial projection 42 that respectively is convexly equipped with of these two cramps, 41 inner faces, be articulated in this two pivoted hole 32 in order to be embedded, and front protection cover 40 roofs have two shoulders that protrude out 43, are to be positioned at its roof top after articulating with rear shield 30, make front protection cover 40 can this two projection 42 up start predetermined angular for pivot, and can return original position, but beat downwards.
At least one flexible member 50 is in order to providing this elasticity that front protection cover 40 remains on original position to return the power of releasing, and present embodiment is provided with two spring leafs, 50, one ends and is fixed on rear shield 30, and the other end inserts for the shoulder 43 of front protection cover 40, and is pressed on this shoulder 43.
In addition, the bottom of this front protection cover 40 is provided with slightly rounded end, a cross section 44, is beneficial to use.
During use, the user hands housing 10, grinds with 20 pairs of work packages of emery wheel, can up start automatically when running into article owing to this front protection cover 40, therefore can not influence normal running.Owing to there is forward and backward guard shield 40,30 to envelope emery wheel 20 jointly, therefore the chip or the spark that can effectively reduce when grinding splashes, and can protect the fine or body skin of user's eye to escape injury.In addition no matter at ordinary times or in using, or use the back and emery wheel still when rotated because the end face of emery wheel and around coated pastly fully, therefore do not have user or other people's false touch emery wheel and cause unexpected injury.Again, the front protection cover 40 of present embodiment is dismantled easily, runs into special occasions, it can be unloaded use, does not have other harmful effect fully.
In addition; as Fig. 1, Fig. 4, shown in Figure 5; two side inner edges at front protection cover 40 can respectively be established a protuberance 45; and be nick shaped in rear shield 30 corresponding protuberances 45 positions; then establish above it and protrude shoulder 33; establish chamfering 34 in the bottom of shoulder 33; so; can cause front protection cover 40 in usual activity point of view scope, protuberance 45 is not had an effect, and starts angle but as desire front protection cover 40 is fixed in maximum; make its stop angle activity; only need front protection cover 40 is up pulled, make protuberance 45 climb up rear shield 30 roofs top via chamfering 34, can clip location (as shown in Figure 5).
As Fig. 6, shown in Figure 7, be the utility model second embodiment, it is the front protection cover that can up start 70 that is pivoted on the rear shield 60 with the flat-faced wheel machine, present embodiment is respectively to establish lug 61,71 in the butt end of two guard shields 60,70, and peg graft with a pin 72 and to be pivoted, a sheathed torque spring 73 on pin 72 in addition, its two end props up two guard shields, 60,70 roofs respectively, so also can reach the effect identical with first embodiment, unique difference is that front protection cover 70 is inconvenient to dismantle.
Again, shown in Fig. 7 label 74, dual side-edge equal chamfering before and after the end 74 of front protection cover 70 bottoms can be set as, its effect is identical with the rounded ends 74 of first embodiment, all is for making when operating, and front protection cover 70 can not produce clip with work package and be easy to up start.
As shown in Figure 8, be the 3rd embodiment, it is that front protection cover 80 is hubbed on the housing 90, can reach the function that up starts equally.Its pin-jointed structure is to establish lug 81 on front protection cover 80, and establishes lug 91 at housing 90 front ends, by a pin 92 with its pivot joint, and on pin 92 a sheathed torque spring 93, provide front protection cover 80 to remain on the elastic force of original position.
What need add a supplementary explanation is that this front protection cover is made the best with transparent plastic again.
