Description
Technical field
This utility model relates to machine security guard technology field, particularly to a kind of hand operated grinding wheel machine interlocking protection dress
Put.
Background technology
Hand operated grinding wheel machine is easy to operate, and use cost is low, is widely used in cutting tubing, round steel class;Grooving, chamfering etc. are cut
Processing.But owing to its design specification and safety standard requirement are insufficient, the potential safety hazard of abrasive machine itself is more, adds operator
The safety consciousness of member and Safety skill are weak, cause the event of hurting sb.'s feelings to happen occasionally.Being found by statistics, hurting sb.'s feelings of abrasive machine is main
Reason causes due to grinding wheel explosion, and the grinding wheel of currently the majority is addition bonding agent in abrasive material, through pressed compact, does
Dry and roasting and the porous body made, workmanship difference is relatively big, during use, is firmly difficult to ensure that equilibrium, it is easy to because power
Measure excessive cause grinding wheel explosion hurt sb.'s feelings.
Utility model content
The purpose of this utility model is to provide a kind of hand operated grinding wheel machine interlocking preventer, it is to avoid grinding wheel explosion wound
People, improves the safety that hand operated grinding wheel machine uses.
For realizing object above, the technical solution adopted in the utility model is: a kind of hand operated grinding wheel machine interlocking preventer,
Including motor, grinding wheel, grinding wheel protective cover and base, grinding wheel is fixed in grinding wheel protective cover by rotating shaft, motor
Driving grinding wheel rotates, and grinding wheel protective cover and motor are each attached on base, hinged on grinding wheel protective cover or base
Interlocking protective cover, interlocking protective cover can be located on the position between operator and grinding wheel or is positioned at when rotating and do not blocks
Operator observe on the position of grinding wheel.
Compared with prior art, there is techniques below effect in this utility model: by arranging interlocking protective cover, interlocking protection
Operator can be effectively protected to avoid the grinding wheel being broken time on cover position between operator and grinding wheel
Hurt, have only to when operator need and observe grinding wheel position rotate interlocking protective cover, operate very
Convenient, this simple in construction simultaneously, it is possible to be attached to easily on existing abrasive machine, it is simple to promote practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is three-dimensional structure diagram of the present utility model, wherein eliminates motor, contact switch.
Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 2, this utility model is described in further detail.
Refering to Fig. 1, Fig. 2, a kind of hand operated grinding wheel machine interlocking preventer, including motor 10, grinding wheel 20, grinding wheel protection
Cover 30 and base 40, grinding wheel 20 is fixed in grinding wheel protective cover 30 by rotating shaft, and motor 10 drives grinding wheel 20 to rotate,
Grinding wheel protective cover 30 and motor 10 are each attached on base 40, and grinding wheel protective cover 30 or base 40 are hinged with interlocking
Protective cover 50, interlocking protective cover 50 can be located on the position between operator and grinding wheel 20 or is positioned at when rotating and do not blocks
Operator observe on the position of grinding wheel 20.By arrange interlocking protective cover 50, interlocking protective cover 50 be positioned at operator and
The grinding wheel 20 that can effectively protect operator to avoid being broken time on position between grinding wheel 20 hurts, and works as operation
Personnel need to have only to when observing grinding wheel 20 position rotate interlocking protective cover 50, operate very convenient, simultaneously
This simple in construction, it is possible to be attached to easily on existing abrasive machine, it is simple to promote practicality.
Operator when operation, sometimes can forget to turn to interlocking protective cover 50 operator and grinding wheel 20 it
Between position on, so start after abrasive machine the most dangerous, in order to avoid the generation of this situation, excellent in the present embodiment
Selection of land, is provided with trigger element, interlocking protection between described interlocking protective cover 50 and grinding wheel protective cover 30 or base 40
Time on cover 50 positions between operator and grinding wheel 20, trigger element action allows motor 10 to be energized.Trigger element moves
After work, it is allowed in the case of motor 10 energising, as long as operator open the switch of motor 10, motor 10 will start;If
Trigger element is not operating, and now motor 10 does not allow energising, even if operator open the switch of motor 10, motor 10 is still
Can not start.
The structure of interlocking protective cover 50 has a variety of, as long as protective action can be played, provides one in the present embodiment
Planting preferred embodiment, described interlocking protective cover 50 is hinged on protective hood of grinding wheel 30, and interlocking protective cover 50 includes two panels
The fanning strip 51 being arranged in parallel and the arc 52 connecting two fanning strips 51, the plate face of two fanning strips 51 is parallel to emery wheel
The plane at sheet 20 place, arc 52 is perpendicular to the plate face of fanning strip 51, and the lower end of arc 52 is touched against time on the base 40 it
Bill metaaction.The interlocking protective cover 50 being made up of fanning strip 51 and arc 52, structure is very simple effectively, also can simultaneously
It is hinged on easily on protective hood of grinding wheel 30.
Similarly, the structure of trigger element has a variety of, one of them fanning strip 51 is offered in the present embodiment preferably
Having bar hole 511 and contact switch 512, the length direction of bar hole 511 is the center of circle and the interlocking protective cover of arc and this arc
The center of rotation of 50 overlaps, and grinding wheel protective cover 30 is fixedly installed projection 31 and passes from bar hole 511, arc 52
Lower end is resisted against on contact switch 512 permission motor 10 against projection time on the base 40 it 31 and is energized.In position shown in Fig. 1,
Projection 31 and contact switch 512 lean, now, it is allowed to motor 10 is energized, it will be seen that interlocking now is prevented from figure
Guard shield 50 can protect operator well;When interlocking protective cover 50 is rotated up by operator, projection 31 and contact
Switch 512 is separated, and does not allow motor 10 to be energized, even if now operator open the on and off switch of motor 10, can not open
Galvanic electricity machine 10, protected effect is the best.
