The specific embodiment
Shown in Figure 2 such as Fig. 1, described building hoist secondary circuit master controller, comprise a support 1, be provided with boatswain chair 2 above the support 1, be provided with lower boatswain chair 3 below the support 1, be provided with locating piece 4 in the support 1, upper boatswain chair 2 is provided with handle bar 5, handle bar 5 is connected with locating piece 4, is provided with square shaft 7 by axle sleeve 6 in the locating piece 4, and the front end of square shaft 7 is provided with cam 8, the rear end of square shaft 7 is provided with spring and pulls out plate 9 and spring housing 10, spring housing 10 is provided with retracing spring 11, and an end and the spring of retracing spring 11 pulls out plate 9 and be connected, and the other end is connected with square shaft 7; Lower boatswain chair 3 is provided with contact fixing plate 12, and contact fixing plate 12 is provided with contact-box 13, and contact-box 13 is provided with roller 14 and contact 15; Handle bar 5 is provided with handle lower cover 16 and handle loam cake 17, is provided with self-locking spring 18 in the handle lower cover 16, and the bottom of self-locking spring 18 is connected with handle lower cover 16, and the top is connected with handle loam cake 17; Be provided with gear spring 19 in the locating piece 4, gear spring 19 is provided with gear steel ball 20, and gear steel ball 20 is provided with gear plate 21, and gear plate 21 is connected with support 1; Handle bar 5 is provided with dust boot 22.
During operation, use the grasped handle bar, mention the handle lower cover, lock function is removed, and then handle bar can promote front and back, by the swing handle bar, the cam that makes square shaft and be fixed on the square shaft rotates, and the rotation of cam makes the corresponding closing of contact or disconnection and starts main motor.Each file location is that the elastic force by the gear spring is realized the bump of steel ball and gear plate, and sends clear and melodious sound.When quitting work no matter in any position, as long as decontrol the hand of grasping member bar, will under the effect of retracing spring torsion, make handle bar return to zero-bit, under the effect of self-locking spring, the handle lower cover presses down and blocks boatswain chair, even at this moment careless hand run on the handle bar or other External Force Acting to handle bar, handle bar can not swing yet.So just can not make machine startup produce misoperation.Compare with the change-over swith of original employing, operating personal is Labor-saving safety more, and is more humane.The utility model compact conformation, transmission accuracy is high, and the contact commonality is good, gear good hand touch, and long service life.
