Embodiment 1

[0015] Embodiment 1, a new type of complete equipment drawer multifunctional operating device, refer to Figure 1-Figure 6 , the moving shaft 1 is movably installed in the upper sleeve of the frame 2, the front end of the moving shaft 1 is set with a positioning plate 4, the positioning plate 4 is connected to the turntable 14 installed below it through the connecting rod 10, and one end and the middle of the swing rod 11 Shafts are installed on the frame 2 and the rotating disk 14 respectively, so that the positioning plate 4, the connecting rod 10, the rotating disk 14, the moving rotating shaft 1, and the frame 2 form a four-bar linkage mechanism. 1. Go through the inner wall 5 of the frame and extend into the hollow front end of the circuit breaker control shaft 8. The front end of the circuit breaker control shaft 8 is fixed with a circuit breaker control shaft turntable 6, and the spring 7 is set on the circuit breaker control shaft turntable 6 and the frame 2. On the ci...

Embodiment 2

[0016] Embodiment 2, a new type of complete equipment drawer multifunctional operating device, refer to Figure 2-Figure 7 , on the basis of Embodiment 1, a limit screw 9 that limits the movement of the circuit breaker control shaft turntable 6 is provided in the frame 2, and the others are exactly the same as Embodiment 1.

[0017] When using the present invention, when the circuit breaker is in the opening position, the operating handle will automatically enter the moving shaft 1 when the drawer panel is closed, and the moving shaft 1 and the transmission pin 15 mounted on it can be pushed along the machine by pushing the operating handle. The positioning groove 16 of the inner wall 5 of the frame pushes the turntable 6 on the control shaft 8 of the circuit breaker to compress the spring 7 and enters the positioning groove of the control shaft 8 of the circuit breaker. Turning the operating handle clockwise can drive the control shaft 8 of the circuit breaker to rotate clockw...

Abstract

The invention discloses a multi-functional operation device for drawers of novel complete equipment. The operation device is characterized in that a positioning plate is sleeve at the front end of a movable rotating shaft on a rack, and connected with a rotary table for mounting a swing link through a connecting rod; the movable rotating shaft extends into a hollow core at the front end of a circuit breaker control shaft; a circuit breaker control shaft rotary table is arranged at the front end of the circuit breaker control shaft; a spring is sleeved on the circuit breaker control shaft; a driving pin of the movable rotating shaft extends into a shaft sleeve of the positioning plate, a shaft hole in the inner wall of the rack and a locating slot in a hollow wall at the front end of the circuit breaker control shaft; positioning grooves are uniformly distributed on the circumference of the positing plate and the circuit breaker control shaft; a locating plate spring is in interface contact with an external circumference of the positioning plate and the circuit breaker control shaft rotary table; and a protruded pin mounted on the rotary table is in contact with a microswitch. The device provided by the invention has the characteristics of novel structure, convenience in positioning and reliability in control, and can reduce the occupation of measurement and control board space of a drawer unit, expand use functions of the drawer unit, and realize single-step operation of a single handle.
