Abstract

The utility model discloses a switch structure of a hand-hold power driven grinding tool, comprising a left shell, a right shell, a guidance sliding groove, a switch pushing plate and a switch, the left shell and the right shell form a shell of the hand-hold power driven grinding tool, the guidance sliding groove is arranged on the left sheep and the right shell or between the left shell and the right shell, the switch pushing plate moves along the guidance sliding groove, the switch is arranged in the shell, the switch pushing plate drives a pushing button of the switch to move; the switching on and locking of the switch are two actions, but the resetting of the switch is one action; the operation safety is improved without affecting the using convenience.

Description

The construction of switch of hand electric grinding tool

Technical field

The utility model belongs to the construction of switch of hand held electric tool, the construction of switch of particularly a kind of hand electric grinding tool (hereinafter to be referred as electric mill).

Background technology

Hand held electric tool (hereinafter to be referred as instrument) is the portable type electric tool, and is of a great variety, comprises that electric hand drill, hand grinding tool, electric screwdriver, percussion drill, electricity remove son, electric hammer, electric hand saw etc.These instruments are industrial and agricultural productions, and what use on building, the building site, mine also is at most that the more consumer of shock hazard takes place.This mainly is because the people directly contacts with instrument, in case instrument is charged, bigger electric current will be arranged by human body, and simultaneously, instrument is held in the hand use, and the operator is in case electric shock owing to contraction of muscle is difficult to break away from electrical body, also causes serious consequence easily.

Conventional hand electric grinding tool grips for convenient, and build is more elongated, and during actual the use, the holding area of hand is near output, and the range switch position is far away, and when the user operated machines, conventional self-locking rocker switch safety coefficient was lower.

The utility model content

The purpose of this utility model be to provide a kind of simple in structure, easy to assembly, use reliable, the electric mill switch that safety coefficient is higher.

The technical solution that realizes the utility model purpose is: a kind of construction of switch of hand electric grinding tool, comprise left casing, right casing, guide chute, switch push pedal and switch, left side casing, right casing are formed the casing of hand electric grinding tool, on the left casing, on the right casing or between left casing and the right casing guide chute is set, the switch push pedal is moved along guide chute, switch is arranged in the casing, is driven the push button motion of switch by the switch push pedal.

The utility model compared with prior art, its remarkable advantage is: two actions are resolved in the unlatching and the locking of switch, and resetting of switch remains an action.Under the prerequisite that does not influence ease of use, improved processing safety.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

In conjunction with Fig. 1, the construction of switch of the utility model hand electric grinding tool, comprise left casing 1, right casing 2, guide chute 3, switch push pedal 4 and switch 5, left side casing 1, right casing 2 are formed the casing of hand electric grinding tool, guide chute 3 can be arranged on the left casing 1, on the perhaps right casing 2, between perhaps left casing 1 and the right casing 2, switch push pedal 4 is moved along guide chute 3, switch 5 is arranged in the casing, be fixed on the rib of left casing 1 and right casing 2 inside, drive the push button motion of switch 5 by switch push pedal 4.

Wherein, the construction of switch of hand electric grinding tool of the present invention, guide chute 3 is made up of first slideway 31 and second slideway 32, and first slideway 31 links to each other with second slideway, 32 structures, and the angle theta between first slideway 31 and second slideway 32 is 0＜θ≤90 °.

In conjunction with Fig. 2, switch push pedal 4 comprises control panel 41 and push pedal 43, this control panel 41 is connected with push pedal 43 by neck 42, left side casing 1 and right casing 2 are clipped in the middle the neck 42 of switch push pedal 4, this neck 42 slides in first slideway 31 and second slideway 32, control panel 41 is on corresponding housing, as the switch panel of peripheral operation.The push pedal 43 of switch push pedal 4 drives the unlatching and the locking of the push button realization grinding tool of switch 5, and the push button of switch 5 drives switch push pedal 4 motions and realizes that grinding tools are in stopped status.Switch 5 is an automatic reset switch, can be reciprocating type automatic reset switch, seesaw type automatic reset switch or some dynamic formula automatic reset switch.

Switch push pedal 4 is slided spacing to first slideway 31 along first slideway 31 of guide chute 3, and switch 5 promptly is in opening ON, this moment instrument start-up, but switch 5 can not be locked in opening, as Fig. 5 and Fig. 6.Switch push pedal 4 continues to slide along second slideway 32 of guide chute 3, slides spacing to second slideway 32, and switch push pedal 4 and switch 5 are locked together, and machine is in and starts lock-out state LOCK, as Fig. 7 and Fig. 8.When needing closing tool, switch push pedal 4 is slided in the other direction along second slideway 32, switch push pedal 4 and switch 5 will automatically reset to stopped status OFF, as Fig. 3 and Fig. 4.
