Abstract
A trigger speed regulation switch mainly consists of a main trigger (1), a circular limit ring (2) and a trigger locking rod (3), wherein, a circular limit ring (2) is arranged around a main switch taper rod (15), an edge limited block (21) is arranged on the limit ring, a locking rod limit block (31) is arranged in the middle part of the trigger locking rod (3). When the switch remains a required limiting state, turn the switch trigger knob (11) to the lowest speed state, shift a trigger (12), the switch will not be locked, at this time, the edge limited block (21) and the locking rod limit block (31) contact positively on a straight line. This structure prevents the switch of the trigger (12) can not rebound normally and cause a risk that the machine can not top turning normally. The utility model structure is simple and reliable, low production cost, easy operation and maintenance, which can be widely used for hardwire tools and electric tools etc.
Description
Technical field
The utility model relates to a kind of switch, especially a kind of switch with trigger speed-regulating function.
Background technology
The trigger speed-regulating switch function that often goes up at present is similar substantially, but following defective is arranged:
When switch is in the spacing state of needs, when half trigger knob is screwed into the lowest speed position, press trigger action and Push switch lock-button, the switch closure locking, again with the trigger knob towards switch high speed position rotation up to revolve motionless till, press trigger action once more, switch can not resilience.If above-mentioned situation occurs in the complete machine use, switch can not resilience equals the disjunction disabler of switch, the result will make the complete machine can not stall so, and that will cause major safety risks to personnel's life, not meet the requirement of GB GB-15092 and international standard IEC-61058.
Summary of the invention
According to background technology, the purpose of this utility model is to avoid above-mentioned defective, a kind of follow-on trigger speed-regulating switch is provided, this switch is in when needing spacing state, when the trigger knob is screwed into switch lowest speed position, press trigger action and Push switch lock-button, switch can not closed-lock, this has just been avoided the generation of dangerous situation, and switch can not lose efficacy yet.
To achieve these goals, of the present utility model being achieved through the following technical solutions:
A kind of trigger speed-regulating switch, mainly by trigger main body (1), circular spacing collar (2) and trigger lock bar (3) are formed, wherein: trigger knob (11), trigger (12), rotating driving lever (13), lock-button (14), main body push shaft (15) and trigger lock bar (3) are set on trigger main body (1), in the periphery of trigger main body push shaft (15) circular spacing collar (2) is installed, a circle limit guide vane end stop (21) is set on its circular edge, be provided with securing rod guide vane end stop (31) in the middle part of trigger lock bar (3), also be provided with securing rod circular hole (32); Rotating driving lever (13) drives circular spacing collar (2) at reverse position by transmission and rotates, can make securing rod circular hole (32) can not arrive the lower position of lock-button (14), cause circle limit guide vane end stop (21) and securing rod guide vane end stop (31) on same straight line the two just normotopia contact.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the utility model finishes the structure improvement on the basis of 200520113707.X patent; prevented switch when high speed position by trigger action; switch normally resilience causes the machine normally danger of stall in use, makes the utility model meet the requirement of GB GB-15092 and international standard IEC-61058 fully.
2, the utility model architecture advances is reasonable, and is with low cost, and working service is repaired simple and easy.

Embodiment
Illustrate by Fig. 1, Fig. 2 A, Fig. 2 B, Fig. 3 A and Fig. 3 B, a kind of trigger speed-regulating switch, mainly by trigger main body 1, circular spacing collar 2 and trigger lock bar 3 are formed, wherein: trigger knob 11, trigger 12, rotating driving lever 13, lock-button 14, main body push shaft 15 and trigger lock bar 3 are set on trigger main body 1, in the periphery of trigger main body push shaft 15 circular spacing collar 2 is installed, a circle limit guide vane end stop 21 is set on its circular edge, be provided with securing rod guide vane end stop 31 in the middle part of trigger lock bar 3, also be provided with securing rod circular hole 32; Rotating driving lever 13 drives circular spacing collar 2 at reverse position by transmission and rotates, and can make securing rod circular hole 32 can not arrive the lower position of lock-button 14, cause circle limit guide vane end stop 21 and securing rod guide vane end stop 31 on same straight line the two just normotopia contact.
As can be known, a circle limit guide vane end stop 21 is set on the circular spacing collar limit in the 200520113707.X patent, has again, original shape is changed into the right angle, promptly become securing rod guide vane end stop 31 at the bending part of switch trigger lock bar.
When switch is in the spacing state of needs, rotating driving lever 13 can drive circular spacing collar 2 by transmission and rotate, so circle limit guide vane end stop 21 and securing rod guide vane end stop 31 just on same straight line normotopia contact, because the interaction of two guide vane end stops, limited the movement travel of trigger 12, make the securing rod circular hole 32 of trigger lock bar 3 can not normally arrive lock-button 14 under the position, pressing lock-button 14 switches can not the normally closed locking.So the trigger speed-regulating switch can not appear commonly using, when pressing lock-button 14 with trigger lock, again trigger knob 11 towards the rotation of switch high speed position direction up to revolve motionless till the time, press trigger action 12 again, switch is the failure state of resilience normally.
Be in when not needing spacing state at switch, the dislocation of Push switch trigger 12, two guide vane end stops, switch freely moves, and arriving fast state at switch can closed-lock.
