After the pressing member presses a rocking arm, the contact portion enables the pressing member to reset through the shrapnel, the moving contact block under the action of no force constantly remains in the reset right state, and operation flexibility of the switch is guaranteed.
Description
Technical field
The utility model relates to a kind of light control appliance, and more particularly, it relates to a kind of pressing piece for point driving switch.
Background technology
At present, the control switch of illuminating lamp adopts traditional mode always, unalterable, be similar to the key switch of ship type structure or other structures, but the switch of this structure is widely used, cause people's aestheticly tired, therefore for weeding out the old and bring forth the new, occurred the some moving type switch for controlling illuminating lamp.Point driving switch swings sliding piece by pressing piece control rocking arm, changes the open/close states of circuit, as shown in Figure 4.But more than existing pressing piece, exist shortcomings, for example pressing piece, pressing after rocking arm easily generation and can not ajust the situation of reset, causes switching manipulation dumb, and therefore its structure is needed optimization badly.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of pressing piece for point driving switch of flexible operation.
For achieving the above object, the utility model provides following technical scheme: a kind of pressing piece for point driving switch, comprise pressing piece body, described pressing piece body is provided with the cavity volume of movable contact piece and opening, the structure setting in T shape of described movable contact piece profile, this movable contact piece comprises installation portion and contact part, described installation portion is placed in and in cavity volume, is riveted on pressing piece body, the openend of described pressing piece body is provided with shell fragment, described shell fragment cross section basic configuration is a day character form structure setting, this shell fragment is provided with the breach for accommodating installation portion, described contact part is inconsistent with respect to end face and the shell fragment of installation portion one side.
Described contact part is provided with resistance surface with respect to the other end of installation portion, and described resistance surface both sides are equipped with inclined plane.
The openend of described pressing piece body is provided with erection column, and described shell fragment is provided with the installing hole for being connected with erection column eye-splice.
In described cavity volume, be provided with the limiting section for limiting movable contact piece pendulum angle.
A kind of pressing piece for point driving switch, comprise pressing piece body, described pressing piece body is provided with the cavity volume of movable contact piece and opening, the structure setting in T shape of described movable contact piece profile, this movable contact piece comprises installation portion and contact part, described installation portion is placed in and in cavity volume, is riveted on pressing piece body, the openend of described pressing piece body is provided with shell fragment, described shell fragment cross section basic configuration is a day character form structure setting, this shell fragment is provided with the breach for accommodating installation portion, and described contact part is inconsistent with respect to end face and the shell fragment of installation portion one side.By adopting technique scheme, pressing piece is being pressed after rocking arm, and contact part can be resetted by shell fragment, makes movable contact piece in the time not being subject to active force, remain the reset mode of ajusting, and guarantees the flexibility of switching manipulation.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model is described further for the pressing piece embodiment of point driving switch.
A kind of pressing piece for point driving switch, comprise pressing piece body 1, described pressing piece body 1 is provided with the cavity volume 11 of movable contact piece 2 and opening, the structure setting in T shape of described movable contact piece 2 profile, this movable contact piece 2 comprises installation portion 21 and contact part 22, described installation portion 21 is placed in and in cavity volume 11, is riveted on pressing piece body 1, the openend of described pressing piece body 1 is provided with shell fragment 3, described shell fragment 3 cross section basic configurations are a day character form structure setting, this shell fragment 3 is provided with the breach 31 for accommodating installation portion 21, described contact part 22 is inconsistent with respect to end face and the shell fragment 3 of installation portion 21 1 sides.The installation portion of movable contact piece 2 21 is inserted in cavity volume 11, by the mode of riveted joint, movable contact piece 2 is connected with pressing piece body 1 is movable again, pressing piece is being pressed after rocking arm, no matter the left side of contact part 22 or right side contact with rocking arm and produce skew and swing, contact part 22 all can be by shell fragment 3 by its reset, make movable contact piece 2 in the time not being subject to active force, remain the reset mode of ajusting, guarantee the flexibility of switching manipulation.
Described contact part 22 is provided with resistance surface 221 with respect to the other end of installation portion 21, and described resistance surface 221 both sides are equipped with inclined plane 222.When pressing piece body 1 is stressed while pressing straight down, inclined plane 222 has guide effect, is conveniently located at the stressed motion of rocking arm of 22 belows, contact part, is conducive to improve the flexibility of switching manipulation.
The openend of described pressing piece body 1 is provided with erection column 12, and described shell fragment 3 is provided with the installing hole 32 for being connected with erection column 12 eye-splices.Shell fragment 3 is connected with pressing piece body 1 with the eye-splice realization of erection column 12 by installing hole 32, and this easy enforcement simple in structure convenient is fixedly mounted on shell fragment 3 on pressing piece body 1, avoids shell fragment 3 to drop and affects the serviceability of switch.Erection column 12 can be located at the relative both sides of openend, and this structure has improved the installation steadiness of shell fragment 3, makes shell fragment 3 can not produce skew or rotate.
In described cavity volume 11, be provided with the limiting section 13 for limiting movable contact piece 2 pendulum angles.The angle that limiting section 13 swings for limiting movable contact piece 2, avoid pressing piece body 1 stressed when excessive, increase to the amplitude pressing down, make pressing piece body 1 excessive with the juxtaposition metamorphose of rocking arm, increased the pendulum angle of movable contact piece 2, make shell fragment 3 bending distortion excessive simultaneously, exceed the field of load of shell fragment 3, thereby reduced the useful life of shell fragment 3 or even directly damaged, therefore limiting section 13 can avoid shell fragment 3 stressed excessive, is conducive to extend the useful life of shell fragment 3.
