in order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of micro switch fixing structure for electric push rod, it is characterized in that: comprise being located at the fixed head assembly that push rod below is used for fixing sensitive switch, described fixed head assembly comprises fixed plate I and the fixed plates II of mutual fastening, be provided with the inserted link corresponding with installing hole on sensitive switch between fixed plate I and fixed plates II, also be provided with between fixed plate I and fixed plates II and prevent that fixed plate I and fixed plates II from clamping the protection structure of sensitive switch, be provided with pushing rod sleeve outside push rod, the bottom of pushing rod sleeve is provided with the caulking groove of setting-in fixed head assembly.
Further, the bottom of described fixed plate I is provided with draw-in groove, and the bottom of fixed plates II is provided with the card article of fastening corresponding to draw-in groove.Simple, Stability Analysis of Structures are installed.
Further; described protection structure comprises the cylinder that is located on the fixed plate I madial wall and is located at bossy body corresponding with cylinder on the fixed plates II madial wall; the top end face of cylinder is provided with groove; after fixed plate I and fixed plates II fasten; bossy body embeds in groove; the top end face of cylinder is against on the fixed plates II madial wall, and the length of cylinder is greater than the width of sensitive switch.Avoid fixed plate I and fixed plates II to fasten in the caulking groove of packing into and afterwards sensitive switch is clamped the service behaviour that affects sensitive switch.
Further, described cylinder is located at the both sides of mounted sensitive switch.Only need on the installation site of assurance sensitive switch, enough horizontal spaces be arranged.
Further, described inserted link is located on the madial wall of fixed plate I, and the length of inserted link is not more than the width of sensitive switch.Single hinge pedestal structure, easy to process.
Further, described inserted link comprises the inserted link I and the vertical inserted link II that is located on the fixed plates II madial wall that vertically is located on the fixed plate I madial wall, and the length sum of inserted link I and inserted link II is not more than the width of sensitive switch.Two hinge pedestal structures increase bearing value and the stability of inserted link.
Further, the madial wall of described fixed plate I is provided with wiring groove I.
Further, the madial wall of described fixed plates II is provided with wiring groove II.Be convenient to the arrangement of drawing wire of sensitive switch, also can be to drawing the wire protection that plays a role.
Further, described fixed plate I and fixed plates II fasten rear and described caulking groove interference fit.
After adopting technique scheme, the present invention has following advantage: rapid and convenient is installed, in the sensitive switch of having good positioning, has also guaranteed the operating distance between sensitive switch and push rod, make the action of sensitive switch energy fast reaction fork make the action reversed of push rod.
