The utility model adopts the following technical scheme:
the utility model provides a but three station state devices of quick adjustment's looped netowrk cabinet, includes preceding fixed plate, after-fixing board and three micro-gap switch, preceding fixed plate with be fixed with the guide bar between the after-fixing board, the interval is equipped with three direction slider on the guide bar, and every direction slider is fixed with one respectively micro-gap switch, every last still corresponding screw rod adjustment mechanism that is equipped with respectively of micro-gap switch.
Preferably, two guide rods are fixed between the front fixing plate and the rear fixing plate in parallel, three guide sliders are arranged on each guide rod at intervals, three microswitches are fixed on the inner side wall of each guide slider at intervals, two opposite microswitches on the side faces of different guide rods are fixedly connected through a connecting block, and each connecting block is correspondingly provided with one screw rod adjusting mechanism.
Specifically, the screw rod adjusting mechanism comprises a screw rod, a threaded hole is formed in the side wall of the front fixing plate or the rear fixing plate, the screw rod is connected to the threaded hole and parallel to the guide rod, and the tail end of the screw rod is rotatably connected with the connecting block through a bearing.
Furthermore, the screw rod is also connected with a fastening nut positioned on the side surface of the threaded hole.
Preferably, three screw rods are arranged on the same vertical surface at intervals.
Preferably, the connecting block is T-shaped.
From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:
1. the utility model discloses a three station state induction system, be equipped with three direction slider on the guide bar, be fixed with micro-gap switch on every direction slider, it is equipped with a lead screw adjustment mechanism to correspond on every (or every group) micro-gap switch, through every lead screw adjustment mechanism, can adjust every (or every group) micro-gap switch's position accurately, so the three station state induction system of this structure, not only adjust simply fast, and can instruct three station switch's position accurately, prevent that micro-gap switch from not touching because of the offset targets in place, lead to it to lose corresponding instruction function.
2. The utility model discloses a three station state induction system all is equipped with three micro-gap switch on the direction slider on the guide bar of two parallels, makes two micro-gap switch that parallel simultaneously with the lead screw cooperation of three station switches, can prevent that one of them micro-gap switch from breaking down and unable instruction, improved the utility model discloses reliability that three station state induction system used.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details. Well-known components, methods and processes are not described in detail below.
The utility model provides a but three station state devices of quick adjustment's looped netowrk cabinet, refer to fig. 1 to 3, including preceding fixed plate 10, after-fixing plate 20, guide bar 30 and three micro-gap switch 40, parallel fixed has two guide bar 30 between preceding fixed plate 10 and the after-fixing plate 20, the interval is equipped with three direction slider 31 on every guide bar 30, the interval is fixed with three micro-gap switch 40 respectively on the inside wall of every direction slider 31, be located through a connecting block 41 fixed connection between two relative micro-gap switch 40 on different guide bar 30 sides, connecting block 41 is preferably T style of calligraphy.
