The conditional three segmented column direction switches of the utility model, conveniently control location, reduce and control difficulty; Mechanical position limitation is more reliable, stable; Utilize motion bar device, decrease the space that limit stoper takies; Compact structure, can not take space outerpace.
Accompanying drawing explanation
Fig. 1 is the structural representation of conditional three segmented column direction switches described in the utility model;
Fig. 2 is the schematic diagram of the conditional three segmented column direction switches after the utility model installation inner tube, the tube and the outer tube.
Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Conditional three segmented column direction switches as depicted in figs. 1 and 2, comprise the base 11, column 10, primary transmission screw rod 1 and the secondary transmission screw rod 3 that connect successively from top to bottom,
Between column 10 and primary transmission screw rod 1, be provided with fixed block 5, primary transmission block 2 is enclosed within primary transmission screw rod 1 and secondary transmission screw rod 3 and moves up and down along primary transmission screw rod 1 and secondary transmission screw rod 3,
Stroke upper limit position switch 8 below column 10 side is provided with the lower travel limit bit switch 6 above being positioned at and is positioned at,
Opening slot and motion bar fixed groove is respectively equipped with at fixed block 5 and primary transmission block 2 side corresponding with stroke upper limit position switch 8,
Motion bar 12 top is fixedly connected with motion bar fixed groove through stroke upper limit position switch 8, lower travel limit bit switch 6, opening slot from top to bottom successively,
Lower limit collision block 4 is had at the partial fixing of motion bar 12 between lower travel limit bit switch 6 and primary transmission block 2,
Upper limit collision block 12 is provided with in motion bar 12 bottom.
During use, utilize motion bar to move up and down with primary transmission block 2, when primary transmission block 2 drive motion bar 12 moves and top set time, upper limit collision block 9 contacts with stroke upper limit position switch 8, namely arrives upper limit; When primary transmission block 2 drive motion bar 12 move down and bottom set time, lower limit collision block 4 contacts with lower travel limit bit switch 7, namely arrives lower limit.
Directly weld on the pedestal 11 bottom interior pipe C, top is connected with fixed block 5 by screw; Middle pipe B is fitted by inner guide pin bushing and interior pipe C outer wall, and middle pipe B top is connected with primary transmission block 2 by screw; Outer tube A is fitted by inner guide pin bushing and middle pipe B outer wall, and outer tube A top is connected with primary transmission screw rod 1 top by screw, thus protects the stability of inner transmission device and whole direction switch, in order to load applications.
The conditional three segmented column direction switches of the utility model, conveniently control location, reduce and control difficulty; Mechanical position limitation is more reliable, stable; Utilize motion bar device, decrease the space that limit stoper takies; Compact structure, can not take space outerpace.
