Description
Technical field
The utility model relates to the improvement that a kind of trigger speed-regulating switch structure is formed, especially refer to that this structure composition is in the guide vane end stop of reverse position pot life position circle and the guide vane end stop coordination of push rod, during driving switch, be subjected to guide vane end stop and driving lever simultaneously spacing, trigger can only move in fixed range, has reached the reverse limit function of strong ability.
Background technology
Trigger speed-regulating switch function in the market is similar substantially, but following functional defect is arranged:
1, the reverse limit function anti-pressure ability of switch is little, when switch be under the reverse state under pressure after, deformation takes place and makes the switch trigger loosening in switch trigger and push rod easily, influence the normal use of switch, whole switch will lose efficacy in the time of seriously.
2, the reverse limit function compressive resistance of switch all relies on positive and negative transferring to withstand trigger, when switch is under the reverse state under pressurely, make rotating driving lever fracture easily, and cause the reverse limit function of switch to lose efficacy, the motor internal reverse current is excessive like this, seriously shortens motor useful life.
Based on above-mentioned, the structure of trigger speed-regulating switch formed to improve be the task of top priority.
Summary of the invention
According to background technology, the purpose of this utility model is to provide suit one circular spacing collar 2 on a kind of push rod 31 of the pusher body 3 at trigger.The guide vane end stop coordination of the guide vane end stop of spacing collar and push rod when trigger is in reverse position is subjected to guide vane end stop and driving lever simultaneously spacing during driving switch, it is moved in fixed range, has reached the reverse limit function of strong ability.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of trigger speed-regulating switch, mainly by switch main body (1), circular spacing collar (2), pusher body (3) and rotating turn (4) form, wherein: the push rod (31) of switch pusher body (3) is gone up suit one circular spacing collar (2), the edge of the cast structural (21) of its circular spacing collar (2) is shaped on a dwang (22), also be shaped on spacing collar upper limit locating piece (211) and spacing collar lower limit locating piece (212) on it, dwang (22) can move in the main body switch square hole (11) of switch main body (1); Turn in the rotating bottom of (4) is provided with rotating square hole (41), rotating driving lever (42) is provided with cylindrical projections (421), rotating driving lever (42) can make cylindrical projections (421) swing in rotating square hole (41) by axle screw (43), corresponding on rotating square hole (41) and main body switch square hole (11) structure, the cylindrical projections (421) of rotating driving lever (42) places the flute profile mouth (221) of the dwang (22) of circular spacing collar (2); Rotating is turned (4) when being in reverse position, and spacing collar upper limit position block (211), spacing collar lower position block (212) contact with push rod upper limit position block (311), push rod lower position block (312).
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the utility model improvement that the trigger speed-regulating switch structure commonly used is formed has realized the enhancing of reverse limit function anti-pressure ability, has solved the defective of commonly using switch.
2, the utility model is simple in structure, and is sturdy and durable, and working service is repaired simple and easy, can be widely used in hardware ﹠ tools and electric tool etc.

Embodiment
Illustrate by Figure 1A, Figure 1B, Fig. 1 C, Fig. 2 A, Fig. 2 B, a kind of trigger speed-regulating switch, mainly by switch main body 1, circular spacing collar 2, pusher body 3 and rotating are turned and 4 are formed, wherein: suit one circular spacing collar 2 on the push rod 31 of switch pusher body 3, the edge of the cast structural 21 of its circular spacing collar 2 is shaped on a dwang 22, also be shaped on spacing collar upper limit locating piece 211 and spacing collar lower limit locating piece 212 on it, dwang 22 can move in the main body switch square hole 11 of switch main body 1; Be provided with rotating square hole 41 in turn 4 bottom of rotating, rotating driving lever 42 is provided with cylindrical projections 421, rotating driving lever 42 can make cylindrical projections 421 swing in rotating square hole 41 by axle screw 43, corresponding on rotating square hole 41 and main body switch square hole 11 structures, the cylindrical projections 421 of rotating driving lever 42 places the flute profile mouth 221 of the dwang 22 of circular spacing collar 2; Rotating turns 4 when being in reverse position, and spacing collar upper limit position block 211, spacing collar lower position block 212 contact with push rod upper limit position block 311, push rod lower position block 312.
Other knows that at the switch push rod 31 peripheral circular spacing collars 2 of installing, circular spacing collar 2 is made up of cast structural 21 and dwang 22, and after circular spacing collar 2 was contained on the switch main body 1, dwang 22 can move in main body switch square hole 11.
Stay a rotating square hole 41 in switch rotating 4 bottoms of turning, rotating turn 4 install to main body switch 1 after, rotating square hole 41 and main body switch square hole 11 just overlap, dwang 22 can be connected with cylindrical projections 421 on the rotating driving lever 42 by two square holes like this, and can drive circular spacing collar 2 rotations with the rotation of rotating driving lever.When switch is in forward condition, circular spacing collar 2 guide vane end stops and the dislocation of push rod guide vane end stop, switch can full action.When switch is in reverse state, circular spacing collar 2 guide vane end stops and push rod guide vane end stop be normotopia just, adds also normotopia just of trigger and rotating driving lever 42, if driving switch, push rod is in spacing scope, the limited circle guide vane end stop of push rod guide vane end stop withstands, and trigger is withstood by the rotating driving lever, even power under pressure, 3 whiles are stressed, deformation can not take place in trigger and pusher body 3, has guaranteed the reverse operating stability of switch, makes switch durable in use.
