Description

A kind of light modulation pulling switch

Technical field

The utility model relates to a kind of pulling switch, particularly relates to a kind of light modulation pulling switch.

Background technology

Traditional pulling switch adopts ratchet structure, the compartment of terrain is provided with the metal movable contact spring on the ratchet, by the rotation realization movable contact spring of ratchet and contacting or disconnection of static contact, thereby realize that switch lock fixes on the purpose that is switched on or switched off two states, but after long-term the use, this pulling switch causes fault because of ratchet and contact generation abrasion thereof, distortion easily.On the other hand, when being applied to illuminating lamp,, thereby can't realize dimming function because traditional pulling switch only is switched on or switched off two states.

For this reason, the patent No. is that the Chinese utility model patent of ZL93227137.X (notification number is CN2151530U) discloses a kind of light modulation economize on electricity pulling switch, it comprises the device of pulling switch and light modulation combination, and this device is made of light adjusting circuit, ratchet, conducting strip: the variable resistor in the light adjusting circuit is several groups of fixed resistances; Relative with ratchet have a dimmer board, and the stroke of dimmer board and ratchet has several axial symmetry conductive regions for corresponding stroke, and conduction region is connected with its corresponding fixed resistance end respectively; Also be fixed with a metal slip ring on the ratchet shaft, be fixed with contact spring on the slip ring, along with the rotation of ratchet, contact spring contacts with the different conductive regions of dimmer board, and other has a conducting strip, and stiff end inserts light adjusting circuit, and free end contacts with slip ring.Be connected with the controllable silicon brightness of may command lamp of several groups of variable fixed resistances realizes connection, disconnection and the light modulation purpose of lamp.

But this device is still similar to known stayguy switch fabric, needs with four stroke contacts of ratchet lock conducting strip, thereby exists the switch complicated in mechanical structure, and light modulation need be used the action control that repeats backguy, and light-modulating mode is discontinuous.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of continuous light tuning pulling switch that does not adopt ratchet mechanism and do not have wearing and tearing at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this light modulation pulling switch comprises housing and is positioned at the electronic circuit board that it has light adjusting circuit, it is characterized in that including on the described electronic circuit board push-button switch, and in housing, also be provided with seesaw, spring and backguy, described seesaw can be around its pivot swinging, first end of seesaw is aimed at described push-button switch, seesaw also is connected with one can drive the backguy that seesaw is swung, the other end of backguy passes outside the housing, and described spring action is on described seesaw and keep seesaw and keep overcoming the backguy pulling, reply the trend of initial condition.

As a kind of preferred version, described seesaw pivot is good with the middle part that is positioned at seesaw, and described backguy is connected second end of described seesaw away from described push-button switch.

Can make the arrangement of each parts in housing more reasonable like this.Certainly, described backguy first end that is connected the contiguous described push-button switch of described seesaw also is fine.

For described electronic circuit is not directly communicated with the external world, can in housing, be fixed with an electrical equipment cover again, can play the effect of a protection against the tide, isolation like this.

Described seesaw pivot can be arranged on the relatively-stationary axle bed of housing on, this axle bed can be directly fixing with housing, also can be arranged on the described electrical equipment cover.

Compared with prior art, the utility model has utilized a seesaw, a push-button switch and a backguy to make up the function that has realized dimmer switch dexterously, and need not ratchet and contact structure, thereby stopped because of the fault that abrasion, distortion cause takes place, simultaneously mechanical structure is also simplified greatly, with the pulling switch that can realize continuous light tuning after an electronic circuit cooperates.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, this light modulation pulling switch comprises the housing that is made of cover body 11, base plate 12 and is arranged on electronic circuit board 6, electrical equipment cover 3 and safety guard 2 in the housing;

Wherein, electronic circuit board 6 is provided with the light adjusting circuit that comprises push-button switch 61, electrical equipment cover 3 with electronic circuit board 6 covers within it, and be fixed in the lump on the base plate 12 by screw, safety guard 2 again with electrical equipment cover 3 covers within it, expose outside electrical equipment cover 3 lead safely cover cap live, with screw safety guard 2 and electrical equipment cover 3 are fixed as one again;

In electrical equipment cover 3, be provided with seesaw 51, spring 4 and backguy 8, described seesaw 51 dual-sides have the pivot of evagination, insert the axis hole be arranged on the axle bed 31 on electrical equipment cover 3 inwalls, make the seesaw 51 can be around its pivot swinging; First end of seesaw 51 is aimed at the push-button switch 61 of described electronic circuit board 6, and seesaw 51 also then connects described backguy 8 at second end away from described push-button switch 61, the other end of backguy 8 passes outside electrical equipment cover 3, safety guard 2 and the cover body 11, opposite side at seesaw 51 second ends then is provided with a spring that offsets with it 4, and the other end of spring 4 then is embedded in the spring base on electrical equipment cover 3 inwalls;

Described seesaw 51 also is shaped on a banking stop 52 that bends downwards at first end of its contiguous described push-button switch 61, is made the amplitude of fluctuation of seesaw obtain restriction by this banking stop 52 by stopping of axle bed 31.

The part of described backguy 8 outside being positioned at housing is divided into two-section and links to each other by collets 7.

When backguy 8 is not stressed, spring 4 acts on the described seesaw 51, make push-button switch 61 be in off-state, when backguy 8 is subjected to downward pulling force, described switch seesaw 51 swings, its first end is pressed described push-button switch 61, makes the light adjusting circuit work on the electronic circuit board 6, the time that the pulling backguy continues is the closure, the operating time of light adjusting circuit of push-button switch 61 just, thereby reaches the purpose of continuous light tuning; When the pulling force of backguy 8 was removed, pulling switch resetted under the restoring force effect of spring 4, and push-button switch 61 reverts to off-state, and light adjusting circuit quits work.
