Abstract
The invention relates to the technical field of devices used for switching on or switching off electric devices, in particular to a trigger switch. The trigger switch can achieve switching on or switching off instantly and is good on-off performance, so that service life is guaranteed. The trigger switch includes an outer shell, a trigger and a pull rod; a working cavity is formed in the outer shell; one end of the pull rod extends into the working cavity of the outer shell, and the other end of the pull rod is connected with the trigger; a movable block assembly and a pull rod spring are arranged in the working cavity of the outer shell; the movable block assembly comprises movable blocks, a base plate and a contact mechanism and further comprises blocking elastic pieces, wherein the blocking elastic pieces are installed on the inner walls of the working cavity, the outer walls of the movable blocks are provided with reverse U-shaped matching clamping blocks, the blocking elastic pieces are provided with U-shaped matching openings, the left ends of the matching openings make contact with the right ends of the matching clamping blocks when the movable blocks are located at the extreme position at the left end, and the right ends of the matching openings make contact with the left ends of the matching clamping blocks when the movable blocks are located at the extreme position at the right end.
Description
Technical field
The present invention relates to, for opening or close the technical field of the device of electrical appliance, particularly relate to a kind of trigger.
Background technology
As everyone knows, trigger is mainly used in the relatively large angle grinding machine of power, and on the instruments such as cutting machine, these tool types are relatively severe due to environment for use in actual applications, and applied load is relatively heavier, and the useful life of instrument is relatively long; The instrument of these types is harsher comparatively speaking to the requirement of switch.Require switch can bear the instantaneous large-current that instrument produces when starting, and provide stable electric current output in use procedure, Simultaneous Switching can bear very large breaking current of moment when disconnecting, and therefore for core texture action request necessity of switch, can stablize the load current that bears instrument institute product.
Most of similarly switch or electrical endurance are not long in the market, perhaps can't bear powerful tool applications, the design imperfection due to the contact-actuating mechanism part of switch after all, cause can't bearing for a long time in actual use instantaneous large-current switch on and off or the mechanism of switch when just bringing into use, mechanism action is more smooth and easy, cross shelves rapidly, but after the life-span of certain number of times is used, crossing shelves just occurs slowly, sluggishness, the life-span, serious situation about shortening occurred.
Summary of the invention
For solving the problems of the technologies described above, the invention provides and a kind ofly realize that moment is switched on or switched off, thereby the break-make better performances has ensured the trigger in useful life.
Trigger of the present invention, comprise shell, trigger and pull bar, be provided with working chamber in described shell, one end of described pull bar stretches in the working chamber of shell, the other end of described pull bar is connected with trigger, be provided with movable block assembly and pull-rod spring in the working chamber of described shell, described movable block assembly comprises movable block, base plate and contact mechanism, described movable block is fixed on described base plate, described base plate is connected with the end in pull bar stretches to the shell working chamber, one end of described pull-rod spring is connected with the working chamber inwall, the other end of described pull-rod spring is connected with movable block, also comprised the shelves shell fragment, the described shelves shell fragment of crossing is arranged on described working chamber inwall, be provided with down " U " shape on the outer wall of described movable block and coordinate fixture block, the described mistake on the shelves shell fragment is provided with " U " shape birdsmouth, when described movable block is positioned at the left end extreme position, the left end of described birdsmouth contacts with the right-hand member that coordinates fixture block, and when described movable block is positioned at extreme right position, the right-hand member of described birdsmouth contacts with the left end that coordinates fixture block.
Trigger of the present invention, described cooperation fixture block and movable block are integrated design.
Trigger of the present invention, the described shelves shell fragment of crossing is installed on described working chamber inwall.
Compared with prior art beneficial effect of the present invention is: by above-mentioned setting, can be switched on or switched off by the moment of excessively realizing that crosses the shelves shell fragment, thereby the break-make better performances has ensured useful life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
As shown in Figure 1, trigger of the present invention, comprise shell 1, trigger and pull bar 2, be provided with working chamber in shell, one end of pull bar stretches in the working chamber of shell, the other end of pull bar is connected with trigger, be provided with movable block assembly and pull-rod spring 3 in the working chamber of shell, the movable block assembly comprises movable block 4, base plate 5 and contact mechanism, movable block is fixed on base plate, base plate is connected with the end in pull bar stretches to the shell working chamber, and an end of pull-rod spring is connected with the working chamber inwall, and the other end of pull-rod spring is connected with movable block; Also comprised shelves shell fragment 6, crossing the shelves shell fragment is arranged on the working chamber inwall, be provided with down " U " shape on the outer wall of movable block and coordinate fixture block 7, cross on the shelves shell fragment and be provided with " U " shape birdsmouth, when movable block is positioned at the left end extreme position, the left end of birdsmouth contacts with the right-hand member that coordinates fixture block, and when movable block is positioned at extreme right position, the right-hand member of birdsmouth contacts with the left end that coordinates fixture block; By above-mentioned setting, can be switched on or switched off by the moment of excessively realizing that crosses the shelves shell fragment, thereby the break-make better performances has ensured useful life.
Trigger of the present invention, coordinate fixture block and movable block to be integrated design.
Trigger of the present invention, cross the shelves shell fragment and be installed on the working chamber inwall.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
