Above-mentioned closely connected indication notch 5 is positioned at a side on plane on the indication rod 3, scolds with a certain distance from indication notch 6 to be positioned on the indication rod 3 on the plane opposite side apart from closely connected indication notch 5.

A side of above-mentioned closely connected indication notch 5 is inclined-planes.

An above-mentioned side of separating indication notch 6 is inclined-planes.

Above-mentioned Adjustment System 4 comprises adjustment rack 15, adjustable bolt 16 and position-limited rack 18, and adjustment rack 15 is arranged on scolds on expression switches set 2, and adjustable bolt 16 is arranged on the drain pan 17 by position-limited rack 18.

The utlity model has following advantage:

1, sturdy and durable.Because the utility model is arranged on closely connected indication notch on the indication rod with scolding from indication notch, only realize detection to tongue with an indication rod, indication rod only needs a short indication rod to get final product with being connected of tongue, save long indication rod, solved the fault of easy displacement of indication rod gap position and long indication rod easy fracture.

2, reliability height.The utility model has adopted quick action switch and the adjustable structure of switches set, has realized that tongue just can make closely connected expression switch realize switching on and off with scolding from the expression switch in less traverse, has improved the reliability of closely connected detector.

3, simple in structure, volume is little.Because the minimizing of indication rod quantity and the indication rod of several different traverse scopes, make the utlity model has simple in structure, volume is little and lightweight advantage.

Five, the specific embodiment

Referring to Fig. 1, the utility model mainly is made up of switches set 1 and 2, indication rod 3 and Adjustment System 4.

Referring to Fig. 2, a side on the last plane of the utility model indication rod 3 has a closely connected indication notch 5, and the last plane of indication rod 3 has with a certain distance from the opposite side of above-mentioned closely connected indication notch 5 scolds from indication notch 6.

Referring to Fig. 3, the utility model switches set is made up of quick action switch 7, switch frame 8, carriage 9, roller bearing 10, bracket axle 11 etc., roller bearing 10 is fixed on the carriage 9, bracket axle 11 is fixed on the switch frame 8, roller bearing 10 can be along the last plane rolling of indication rod 3, one end of carriage 9 and bracket axle 11 are for being rotationally connected, and the other end of carriage 9 contacts with the roller 12 of moving quick action switch 7.When roller bearing 10 is positioned on the breach bottom surface 14, the contact of quick action switch 7 is in normally closed position, when the motion of indication rod 3 makes roller bearing 10 the 13 last in-planes to indication rod 3 moves along the inclined-plane, because of roller bearing 10 is to be fixed on the carriage 9, carriage 9 is upwards swing of center with bracket axle 11, and roller 12 upward movements of promotion quick action switch, the motion of roller 12 makes the state of quick action switch 7 change, in a single day quick action switch 7 leaves normally closed position, just be converted to normally open position (normal opened contact connection) rapidly, when the motion of indication rod makes roller bearing 10 by inclined-plane 13 during to bottom surface 14 motions, the normally open position that will cause quick action switch 7 is converted to normally closed position (normally closed contact connection) rapidly.Described switches set is two, and one is closely connected expression switches set 1, is used for realizing the detection of switch point housing position; Another is for scolding from expression switches set 2, and it is used for realizing that tongue scolds the detection of offing normal.

Referring to Fig. 4, the utility model Adjustment System 4 comprises adjustment rack 15, adjustable bolt 16 and position-limited rack 18.Adjustment rack 15 is fixed on scolds on expression switches set 2, adjustable bolt 16 is assemblied on the drain pan 17 by position-limited rack 18, adjustable bolt 16 can only rotate and can not move forward and backward, and by the rotation of adjustable bolt 16, adjustment rack 15 is moved forward and backward the traverse that tongue needs with scolding from expression switches set 2.
