The utility model is characterized in that the center part of the main shaft is provided with a short shaft, and the short shaft and the main shaft are mutually perpendicular and form a crossed universal joint; the both ends of the short shaft are provided with U-shaped connecting rods, and convex columns at the bottom parts of the U-shaped connecting rods are inserted into the connecting holes of a rotating shaft; the rotating shaft penetrates through a mounting hole at the bottom of the bracket and is fixed by a shaft sleeve of the bolt hole, and the end surface of the shaft sleeve is provided with a square hole which can be connected with a square activating tenon at the head part of a bending handle; the edge side of the mounting hole at the bottom of the bracket is provided with a positioning stop block; the outside periphery of the mounting hole is provided with two locating holes.
Description
The utility model relates to a kind of operating mechanism that is used for low pressure isolation switch contact deciliter.
The low pressure isolating switch is made up of switch contact and operating mechanism two parts, the rotation operating mechanism handle can realize switch contact deciliter.The operating mechanism of existing low pressure isolating switch all adopts positive push-pull fashion console switch up and down, this operating mechanism is made up of support, main shaft, pivoted arm, pull bar, spring and handle, main shaft is rack-mount, pivoted arm one end is fixedlyed connected with main shaft, the other end flexibly connects with pin and pull bar, spring is installed in the pivoted arm lower end, and drawing handle can make the motion of pivoted arm and pull bar, realize switch contact deciliter.This operating mechanism is when operation, and operating personnel's arm need move up and down, and movement range is big, application of force inequality; The setting height(from bottom) of its switch on power distribution equipment is subjected to placing restrictions on of operating personnel's height, and the component structure that influences power distribution equipment is arranged; Handle and switch fuse inseparable, influence the installation of power distribution equipment and the maintenance of opening the door.
The purpose of this utility model provides a kind of rotary operating mechanism that is used for low pressure isolation switch contact deciliter, rotatablely moving of handle can be converted into the reciprocating motion that connects the switch contact pull bar, realize switch contact deciliter.
The structure of the operating mechanism that the utility model proposes comprises support, main shaft, pivoted arm, pull bar and handle, main shaft is rack-mount can to rotate, pivoted arm one end is fixedlyed connected with main shaft, the other end flexibly connects with pin and pull bar, it is characterized in that main shaft central authorities are equipped with minor axis, minor axis and main shaft are orthogonal, constitute candan universal joint, the U-shaped connecting rod is equipped with at the minor axis two ends, and the convex cylindrical of U-shaped connecting rod bottom is inserted in the connecting hole of rotating shaft; The frame bottom installing hole is passed in rotating shaft, fix with screw and axle sleeve, the axle sleeve end face be provided with square hole can with bending handle head side active connection of tenon; The bottom installing hole side of support is provided with position block, the installing hole cylindrical is provided with two location holes, another installing hole of rotating shaft is fixed with setscrew nut, and spring and steel ball are housed in the endoporus of setscrew nut, and steel ball can fall into the location hole of frame bottom and locate under the effect of spring.
The compact conformation of the operating mechanism that the utility model proposes, handle can separate with operating mechanism, and fitting operation is convenient.The square tenon of bending handle is inserted the axle sleeve square hole, turning handle, rotating shaft is with regard to transmission U-shaped connecting rod, because connecting rod is connected with the minor axis of candan universal joint, connecting rod rotates main shaft with regard to turning handle, just swing with the fastening pivoted arm of main shaft, the pull bar that is connected with pivoted arm is just reciprocating, the realization switch contact deciliter.
Followingly with reference to accompanying drawing concrete enforcement of the present utility model is further described, shown in Figure 1 is the structure chart of this operating mechanism, and shown in Figure 2 is the A-A cutaway view of operating mechanism.The structure of this operating mechanism comprises support (2), main shaft (3), pivoted arm (11), pull bar (13) and handle (8), main shaft (3) is installed on the support (2) and can rotates, pivoted arm (11) one ends are fixedlyed connected with main shaft (3), and the other end flexibly connects with pin (1) and pull bar (13).It is characterized in that main shaft (3) central authorities are equipped with minor axis (12), minor axis (12) and the orthogonal formation candan universal joint of main shaft (3), U-shaped connecting rod (14) is equipped with at minor axis (12) two ends, and the convex cylindrical (15) of U-shaped connecting rod (14) bottom is inserted in the connecting hole of rotating shaft (16); Support (2) bottom installing hole is passed in rotating shaft (16), and is fixing with screw (10) and axle sleeve (9), axle sleeve (9) end face be provided with square hole can with bending handle (8) head side active connection of tenon; Support (2) bottom installing hole side is provided with position block (17), the installing hole cylindrical is provided with two location holes (7), another installing hole of rotating shaft (16) is fixed with setscrew nut (4), spring (5) and steel ball (6) are housed in the endoporus of setscrew nut (4), and steel ball (6) can fall into the location hole (7) of support (2) bottom and locate under the effect of spring (5).
