Push type intermittent rotary switch (hereinafter referred to as switch), as Fig. 1, shown in Fig. 2, comprise the upper cover 1 and lower cover 2 that snap together, upper cover 1 is provided with multiple switch position, rotating shaft 3 is provided with between upper cover 1 and lower cover 2, the shape and structure of rotating shaft 3 is as Fig. 4, shown in Fig. 5, rotating shaft 3 is provided with gear, on rotating shaft 3, cover has pressing axis 4 pressing axis 4 as shown in Figure 6, the other end of pressing axis 4 exposes upper cover 1 through the pressing hole 103 on upper cover 1, spring 5 is also provided with between rotating shaft 3 and lower cover 2, like this when applying a downward power to the top of pressing axis 3, pressing axis 4 presses down rotating shaft 3, spring 5 is compressed downwards, spring 5 shrinks when stressed can produce a moment of torsion simultaneously, store angle energy, when unclamping the pressing force to pressing axis 3, spring 5 restores to the original state, in the process that it recovers, spring 5 upwards pushes up rotating shaft 3, and make rotating shaft 3 drive pressing axis 4 jointly to move to the direction of upper cover 1, pressing axis 4 and rotating shaft 3 is made to return to original position, spring 5 separation angle energy simultaneously, the torsion produced in reinstatement process drives rotating shaft 3 to rotate, realize contact and the disconnection of the contact on rotating shaft 3 and the contact on upper cover 1.
As the first embodiment of the present utility model, as Figure 1-Figure 5, upper cover 1 and lower cover 2 are rectangle, the two can snap together, upper cover 1 is provided with moving contact 101 and multiple fixed contact 102, as Fig. 1, shown in Fig. 2, four sides of upper cover 1 arrange a moving contact 101, with three fixed contacts 102, convenient in order to describe, three fixed contacts are respectively as B shelves, C shelves and D shelves describe, each gear there is metal contact piece, when installing switch, moving contact and the metal contact on gear and corresponding connection, such as moving contact 101 is accessed main line as sending end, by B shelves, C shelves and D shelves are as the other end place in circuit in loop.
Be provided with slot 201 in the center of lower cover 2, in this slot 201, be provided with spring 5, rotating shaft 3 is provided with between upper cover 1 and lower cover 2, rotating shaft 3 has a rosette 301, rosette 301 center extends to form column 302 towards the direction perpendicular to rosette 301 card, this column 302 is towards upper cover 1, be provided with around the external diameter of column 302 and rotate teeth 303, pressing axis 4 is beam barrel, and be enclosed within column 302, pressing axis 4 is provided with docking and rotates teeth, when pressing axis 4 is enclosed within after on column 302, docking in pressing axis 4 rotates teeth and docks with the rotation teeth 303 around column 302 external diameter, can make to drive pressing axis 4 to rotate when rotating shaft 3 rotates simultaneously, deviate from the card of column 302 at rotating shaft 3, the position relative with column 302 is provided with groove 304, this groove is for holding spring 5, namely when assembling, first spring 5 is placed in the slot 201 on lower cover 2, then rotating shaft 3 is placed on lower cover 2 by groove 304 alignment springs 5 of rotating shaft 3, again pressing axis 4 is enclosed within the column 302 of rotating shaft 3 afterwards, making it between the two by rotating teeth docking, finally upper cover 1 being buckled on lower cover 2.
The edge of the rosette 301 of rotating shaft 3 is provided with a protruding contact 3011, in rotating shaft 3 rotation process, the metal contact piece of moving contact 101 with B shelves or C shelves or D shelves place can contact along with the rotation of rotating shaft 3 by the contact 3011 above rosette 301, accordingly moving contact 101 is communicated with gear D with gear C or moving contact 101 with gear B or moving contact 101, rotating shaft 3 is made of metal, and ensures can be energized smoothly between two gears after being connected by it, for four gears on 1, it will make the height of moving contact 101 will lower than other several gears when arranging, and, the length of spring 5 will meet when rotating shaft 3 is placed on after on spring, the card of its rosette 301 can keep in touch with moving contact 101, when exerting a force to pressing axis 4, rotating shaft 3 moves towards lower cover 2, the card of rosette 301 departs from moving contact 101, after release applied force, rotating shaft 3 under the elastic force effect of spring 5 to upper cover 1 motion return, the card of rosette 301 gets back to initial position simultaneously, keep contacting with moving contact 101, B shelves, C shelves and the position of D shelves on upper cover 1 are higher than moving contact 101, and rotating shaft 3 is in rotary course, and the contact 3011 on its rosette 301 contacts with the fixed contact on each gear, realizes the connection between the moving contact of whole switch and fixed contact.
The center of upper cover 1 is provided with pressing hole 103, and pressing axis 4 exposes to upper cover 1 through pressing hole 103 one end, conveniently operates when in use, when making switch, torsionspring selected by spring 5, guarantees to store enough angle energy, and after making the active force in release pressing axis 4, spring 5 can turn an angle by driven rotary axle 3, realizes the connection between moving contact from different fixed contact, and, when making push type intermittent rotary switch, the angle energy size that can will store according to spring 5 used calculates the anglec of rotation of rotating shaft 3, thus arrange moving contact 101 and the B shelves as fixed contact, distance between C shelves and D shelves, i.e. moving contact 101 and B shelves, C shelves and the distribution of D shelves on upper cover 1, using the rotational angle of spring 5 driven rotary axle 3 as B shelves and C shelves, relative to 1/2nd of the angle of upper cover 1 center line between C shelves and D shelves, like this, in rotating shaft 3 rotation process, contact 3011 on rosette 301 can rest between two adjacent fixed contacts, namely be parked between two gears, form neutral gear, in use, each time after pressing, change the annexation between moving contact and fixed contact, namely after last time pressing, switch is in moving contact and fixed contact connection status, then pressing late contact and fixed contact are off state next time, after last time pressing, switch is in moving contact and fixed contact off-state, then pressing late contact and fixed contact are connection status next time, and this is push type intermittent rotary switch.
At least also there is the second embodiment in the utility model, with the first embodiment unlike, in the second embodiment, upper cover 1 in the upper cover 1 snapped together and lower cover 2 arranges multiple moving contact and fixed contact (can with reference to figure 1 and Fig. 2, this embodiment no longer configures new accompanying drawing), when the circuit needing access comparatively complicated, by the multiple moving contact places in circuit on upper cover 1, can satisfy the demands.
In addition, use between pressing axis 4 with rotating shaft 3 and be threaded, or, also column 302 end in Figure 5 can be installed by a bearing, pressing axis 4 is enclosed within after on column, withstands the inner ring of bearing, then presses down by pressing axis 4 action that bearing completes rotating shaft 3 Compress Spring 5, drive rotating shaft 3 to rotate power being discharged the rear spring 5 separation angle energy that rebounds, thus change the annexation in switch between moving contact and fixed contact.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned execution mode, in the ken that those skilled in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
