In other words, described upper casing, mesochite, lower casing is to form a box body shape by the set screw aggregate erection, wherein, be provided with the conduit cavity that liquid passes through in the described upper casing, be provided with guide hole in this conduit cavity, be to fit by sealed gluing block, the pressure key is installed in the described mesochite, mesochite is provided with the edge mouth of fitting with the described sealed gluing block other end, described pressure key is equipped with main spring and auxiliary spring, press on the key and more be provided with button position and raised line, one end of described main spring is installed on presses under the key, and its other end then is installed on places restrictions on piece, and described lower casing is provided with fine motion vallecular cavity and the groove of installing for sensitive switch, described sensitive switch is provided with inching button, is pushed by the button position of described pressure key.
Wherein, described main spring is together with placing restrictions on piece and being installed in the groove together.
Wherein, an end of described auxiliary spring is installed on the raised line, and the other end of auxiliary spring is installed on the lower casing fixing.
Wherein, described auxiliary spring is positioned at and has the side that parallel pressure key presses down main spring.
Described end of placing restrictions on piece is connected with voltage regulation screw, regulates this voltage regulation screw by rotation, has compressing or loosens the elastic force scope of piece to main spring of placing restrictions on.
Therefore, the beneficial effects of the utility model are, utilize the cooperation of main spring and auxiliary spring, make and press key pressurized following time, can be parallel and not partially side toward pressing down, till button position compressing fine motion ammonium button, by the low-cost and own resilience force of spring, give and install and the use aspect, all better realize the startup effect of sensitive switch.
Description of drawings
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is an exploded view of the present utility model.
Embodiment
See also Fig. 1, shown in Figure 2, the utility model is provided with upper casing 1, mesochite 2 and lower casing 3, wherein, described upper casing 1, mesochite 2, lower casing 3 forms a cassette shapes by the aggregate erection of upper, middle and lower orientation respectively, fixedly form by set screw 4, be provided with the conduit cavity 12 that passes through for liquid in the described upper casing 1, be provided with guide hole 13 in the conduit cavity 12, be to fit by sealed gluing block 11, be equipped with in the described mesochite 2 and press key 22, mesochite 2 is provided with the edge mouth 21 of fitting with described sealed gluing block 11 other ends, sealed gluing block 11 can contact by edge mouth 21 presses key 22, in addition, described pressure key 22 is equipped with main spring 23 and auxiliary spring 24, press key 22 to be provided with button position 221 and raised line 222, wherein, end by main spring 23 is installed on the pressure key 22 times, the other end of main spring 23 then is installed in places restrictions on the piece 25, place restrictions on the fixedly position of main spring 23 of piece 25 by this, described lower casing 3 is provided with fine motion vallecular cavity 32 and the groove of installing for sensitive switch 26 31, and together with placing restrictions on piece 25 and being installed in the groove 31 together, described sensitive switch 26 is provided with inching button 261 main spring 23, one end of described auxiliary spring 24 is installed on the raised line 222, and the other end of auxiliary spring is installed on the lower casing fixing.
