A kind of durable metal push-button switch
Affiliated technical field
The utility model relates to a kind of push-button switch, uses when opening the door in particular for gate inhibition's electric lock, or the metal push-button switch of the firm and durable of doorbell switch use.
Background technology
At present, the button top of existing push-button switch mostly is the contact push-button switch that plastic material is made, and its principle is rotated up and down and the fixed contact connection for utilizing button pressed downwards to stir spring leaf, when user's pressing button, following shortcoming is arranged:
One, owing to adopt plastic material to make button, effect is poor aspect antidetonation, shock resistance, anti-destruction, influences the result of use of push-button switch, and not attractive in appearance.
Two, single rectangular configuration, simple shape is not attractive in appearance.
Three, owing to adopt plastic material to make button, when using button, the stress point of button is inhomogeneous, causes coming off or walking of back-moving spring and contact copper sheet in the push-button switch easily, and Yi Yin force imbalance causes the wearing and tearing of contact copper sheet, causes that at last switch breaks down.
Summary of the invention
Shortcoming at above-mentioned prior art existence, the purpose of this utility model provides the durable metal push-button switch that a kind of antidetonation, shock resistance, employing metal material processing that anti-destructive power is strong form, this durable metal push-button switch is aesthetic in appearance durable, and the scope of application is extensive.
The technical scheme that the utility model adopted is: a kind of durable metal push-button switch includes: can be a up and down vertical movable button (1), extended a pillar (2) in its bottom, and this pillar (2) bottom is provided with a projection (9); One back-moving spring (3); One upper fixed seat cover (4); Be provided with the metal decking (5) of hole in the middle of one; Fixed seating (6) once; One sensitive switch (7), this sensitive switch (7) comprise and drive bar (8); It is characterized in that: after (9) two parts of the pillar (2) of described button (1) and projection were passed the hole of described metal decking (5), the bar (71) that drives that passes described lower fixed seat cover (6) and described sensitive switch (7) again offseted.
In order to make button switch seem more attractive in appearance, be provided with a retainer ring (11) that is fixed on this metal decking at the tapping of described metal decking (5), the top surface of described button (1) is concordant with the top surface of this retainer ring (11).
For convenience of User Recognition and use button, the top surface of described button (1) also can exceed the top surface of this retainer ring (11).
For making the utility model firm and durable, described button (1), retainer ring (11), upper fixed seat cover (4) and lower fixed seat cover (6) are metal material processing and form.
In addition, the two ends of described metal decking (5) are provided with the spiral shell fixing structure (8) that is used for fixing; The bottom of described sensitive switch (7) is provided with the spiral shell fixing structure (10) that is used for fixing; Fixing and be connected various piece of the present utility model by above-mentioned spiral shell fixing structure (8) and (10).
During use, upper fixed seat cover (4) is used for fixing button (1), and lower fixed seat cover (6) is used for fixing and is connected button (1) and metal decking (5), and fixing and be connected sensitive switch (7).Finger pressure button (1) top, compression reseting spring (3), button pillar (11) and projection (9) pressurized insert fixed cover (6) down downwards simultaneously, drive sensitive switch and drive bar (8), the built-in contact of sensitive switch (7) is connected or disconnection, carry out electric inputing or outputing by being electrically connected of terminal, thereby satisfy gate inhibition's electric lock or doorbell switch function.
The beneficial effects of the utility model are: because the creationary employing metal material of the utility model is made each part of push-button switch, and designed new structures such as retainer ring and fixed seating and guaranteed that push-button switch is attractive and durable, significantly lowered mechanical breakdown and can increase useful life.

Embodiment
A kind of durable metal push-button switch as shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of durable metal push-button switch includes: can be a up and down vertical movable button (1), extended a pillar (2) in its bottom, this pillar (2) bottom is provided with a projection (9); One back-moving spring (3); One upper fixed seat cover (4); Be provided with the metal decking (5) of hole in the middle of one; Fixed seating (6) once; One sensitive switch (7), this sensitive switch (7) comprise and drive bar (8); It is characterized in that: described button (1) is fixed on the described upper fixed seat cover (4), after (9) two parts of the pillar (2) of described then button (1) and projection were passed the hole of described metal decking (5), the bar (71) that drives that passes described lower fixed seat cover (6) and described sensitive switch (7) again offseted.
In order to make button switch seem more attractive in appearance, be provided with a retainer ring (11) that is fixed on this metal decking at the tapping of described metal decking (5), the top surface of described button (1) is concordant with the top surface of this retainer ring (11).
As shown in Figure 5, for convenience of User Recognition and use button, the top surface of described button (1) also can exceed the top surface of this retainer ring (11).
For making the utility model firm and durable, described button (1), retainer ring (11), upper fixed seat cover (4) and lower fixed seat cover (6) are metal material processing and form.
In addition, the two ends of described metal decking (5) are provided with the spiral shell fixing structure (8) that is used for fixing; The bottom of described sensitive switch (7) is provided with the spiral shell fixing structure (10) that is used for fixing; Fixing and be connected various piece of the present utility model by above-mentioned spiral shell fixing structure (8) and (10).
During use, upper fixed seat cover (4) is used for fixing button (1), and lower fixed seat cover (6) is used for fixing and is connected button (1) and metal decking (5), and fixing and be connected sensitive switch (7).Finger pressure button (1) top, compression reseting spring (3), button pillar (11) and projection (9) pressurized insert fixed cover (6) down downwards simultaneously, drive sensitive switch and drive bar (8), the built-in contact of sensitive switch (7) is connected or disconnection, carry out electric inputing or outputing by being electrically connected of terminal, thereby satisfy gate inhibition's electric lock or doorbell switch function.
