Example two: as shown in fig. 4, compared with the first embodiment, when the elastic pressing portion 4 is pressed for the first time, the conductive block 24 moves down to contact with the trigger switch 18 on the first telescopic rod 8, at this time, the trigger switch 18 controls the electromagnet 23 to generate magnetism through an electric signal, and adsorbs the iron block 21, and drives the fixed block 17 to slide downward, and at the same time, the V-shaped plate 9 also moves downward, and the third spring 22 is compressed, and then after the elastic pressing portion 4 is released, at this time, the conductive block 24 is separated from the contact with the trigger switch 18, and at this time, the electromagnet 23 loses magnetism, so that under the elastic force of the third spring 22, the fixed block 17 is pushed upward to slide upward, and at the same time, due to the damping arrangement between the fixed block 17 and the sliding groove 20, the fixed block 17 and the V-shaped plate 9 move upward slowly to reset, and then the elastic pressing portion 4 is pressed for the second time, since the first telescopic rod 8 does not extend to the lower part of the conductive block 24, the conductive block 24 can move downwards beyond the first telescopic rod 8, and the conductive block 24 is in contact communication with the positive and negative electrode plates on the lower mounting block 5, so that equipment connected with the conductive block is controlled.
If the elastic pressing part 4 is touched by mistake, then if the elastic pressing part 4 is not pressed for the second time any more, at this moment, the V-shaped plate 9 can slowly move upwards to reset under the elastic action of the third spring 22, and meanwhile, the first telescopic rod 8 can extend to the lower part of the conductive block 24 again to block the conductive block 24, so as to prevent the elastic pressing part 4 from being touched by mistake next time.
Further, a first spring 6 sleeved on the periphery of the lower mounting block 5 is mounted between the conductive block 24 and the indication panel 2.
When the conductive block 24 is pressed for the second time and contacts with the positive and negative electrode plates on the lower mounting block 5, the first spring 6 is also compressed, and the elastic action of the first spring 6 can assist the conductive block 24 and the elastic pressing portion 4 to reset, so as to prevent the elastic pressing portion 4 from being reduced in elastic deformation degree and incapable of automatically resetting after long-term use and aging.
Further, the V-shaped plate 9 is provided with two, the inner wall at the both sides of supporting part 3 all is fixed with second telescopic link 25, the telescopic link of two second telescopic links 25 through install the slider 16 of its outer wall respectively with two 15 inner wall sliding connection of spout on the V-shaped plate 9, and when the V-shaped plate 9 moves down, second telescopic link 25 can stretch out to the direction that is close to down installation piece 5, the one end that two second telescopic links 25 are close to first spring 6 all is fixed with limiting plate 14.
As shown in fig. 2, when the elastic pressing portion 4 is pressed for the first time, the two V-shaped plates 9 will move downward for the first time, while the first telescopic rod 8 contracts away from the conductive block 24, the two second telescopic rods 25 will drive the position-limiting plate 14 to move toward the first spring 6 under the sliding fit of the sliding block 16 and the sliding slot 15, and has a centering effect on the first spring 6, and can prevent the first spring 6 from being deviated, and the elastic pressing part 4 is disabled, and since the distance of the first time conductive block 24 moving downward with the pressing of the elastic pressing part 4 is short, so the compression deformation degree of the elastic air bag 7 is small, simultaneously, the air extraction amount in the corresponding piston tube 11 is small, the downward moving distance of the V-shaped plate 9 is also short, in this way, the extending length of the second telescopic rod 25 is also short, and the limiting plate 14 can only play a role of centering the first spring 6.
Then, when the elastic pressing portion 4 is pressed for the second time, the conductive block 24 will cross the first telescopic rod 8 and contact the lower mounting block 5, and the elastic airbag 7 will be pressed again, and the degree of compression deformation is greater than that of the first time, so that the air extraction amount in the corresponding piston tube 11 will be greater, the downward moving distance of the V-shaped plate 9 will also be longer, so that the extending length of the second telescopic rod 25 will also be longer, so that the limiting plate 14 can enhance the centering extrusion effect of the first spring 6, because, when the elastic pressing portion 4 is pressed for the first time, the deformation degree of the first spring 6 is smaller, after the elastic pressing portion 4 is released, the self-elastic restoring degree of the first spring 6 is smaller, therefore, only the preliminary centering positioning is needed, and when the elastic pressing portion 4 is pressed for the second time, the deformation degree of the first spring 6 is greater, therefore, after the elastic pressing portion 4 is released, the self-elasticity restoration degree of the first spring 6 is relatively large, so that a higher centering effect is required to prevent the first spring 6 from deviating to influence the failure of the elastic pressing part 4 due to aging.
Furthermore, the top of the elastic pressing part 4 is provided with anti-skid grains.
Can the user press splenium 4 according to elasticity through setting up anti-skidding line, press the splenium 4 through elasticity in the difference to set up different lines moreover, can let the user press the splenium 4 according to the elasticity of difference when, have different sense of touch to can press splenium 4 to differentiate to the elasticity of difference.
Further, through die-casting integrated into one piece between instruction panel 2, supporting part 3 and the elasticity pressing part 4, can make supporting part 3 and elasticity press and be connected more closely between the part 4 through integrated into one piece to can also make things convenient for it to produce and assemble, the elasticity presses the life-span of 4 elastic properties of part to improve simultaneously.
Further, limiting plate 14 is close to the outer wall of first spring 6 and opens to the arcwall face, can make limiting plate 14 laminate first spring 6 more through setting up the arcwall face to improve the location effect placed in the middle to first spring 6.
The working principle is as follows: this membrane switch moulds plastics convenient to production and assembly usefulness uses, when pressing splenium 4 for the first time, then elasticity presses splenium 4 to drive conducting block 24 downstream, earlier with the contact of first telescopic link 8, at this moment, the user can feel elasticity and presses splenium 4 to have a pause and feel, then loosens elasticity and presses splenium 4, and elasticity presses splenium 4 to recover under self elastic action this moment.
Meanwhile, the elastic airbag 7 can be squeezed and compressed, meanwhile, the air inside the elastic airbag is extruded out through the one-way air outlet, then after the elastic pressing portion 4 is loosened, the elastic pressing portion 4 restores along with the elastic airbag 7, meanwhile, the elastic airbag 7 sucks out the air in the piston tube 11 through the air guide tube 13, at the moment, negative pressure can be generated in the piston tube 11, the piston plate and the piston rod 10 are driven to move downwards, meanwhile, the second spring 12 is compressed, the piston rod 10 moves downwards, the V-shaped plate 9 is driven to move downwards together, and then the first telescopic rod 8 contracts.
When the elastic pressing part 4 is pressed for the second time, the conductive block 24 moves downwards to contact with the positive and negative electrode plates on the lower mounting block 5 and electrically communicate with the positive and negative electrode plates because the first telescopic rod 8 does not block the conductive block, so that the equipment connected with the conductive block is controlled to work.
