Description
Technical field
The utility model belongs to electric switch field, particularly relates to a kind of pivot pin separating mechanism of automatic change-over.
Background technology
Automatic change-over is widely used in the various places that need uninterrupted power supply, and it has realized the automatic conversion of power supply, to guarantee the reliability of customer power supply.In order to realize the divide-shut brake conversion of two circuit breakers, what current known automatic change-over adopted is the toggle mechanism alternatively up and down activity of both sides of being controlled by driven by motor rotating mechanism, and toggle mechanism drives the divide-shut brake of killer switch.When people need to manually carry out breaking-closing operating, the rotating mechanism structure being connected with motor is fixed, manual rotation needs drive motor to rotate together, the resistance of motor makes people need to apply larger power can rotate rotating mechanism, in addition the resistance that toggle mechanism place parts coordinate, people's manual rotation is more difficult, and also larger to the wearing and tearing of each parts.
Summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of simple in structure, separated with motor while realizing manual rotation control switch, pivot pin separating mechanism of reducing the automatic change-over of rotational resistance is provided.
The utility model is by the following technical solutions: a kind of pivot pin separating mechanism of automatic change-over, comprise motor shaft, be arranged on lateral pin on motor shaft, be set in the rotating mechanism on motor shaft, the lower hole portion that the endoporus of described rotating mechanism has the upper hole portion that matches with lateral pin shape and matches with motor shaft shape; When upper hole portion is positioned at lateral pin place and matches, described motor and rotating mechanism interlock; When pressing down rotating mechanism, upper hole portion departs from lateral pin, and rotating mechanism can rotate alone around motor shaft.
As a kind of improvement, on motor shaft, be arranged with spring, described spring is arranged on the below of rotating mechanism.
As a kind of improvement, the bottom of rotating mechanism has the cylindrical groove for retainer spring.
As a kind of improvement, the top of rotating mechanism has for the boss of rotary handle is installed.
As a kind of improvement, lateral pin and motor shaft are formed in one.
As a kind of improvement, lateral pin and motor shaft are separate design, and lateral pin is arranged in the pin-and-hole on motor shaft.
The beneficial effects of the utility model: lateral pin is set on motor shaft, the upper hole portion match is set on rotating mechanism, when the position of upper hole portion in matching with lateral pin, motor rotarily drives rotating mechanism and rotates; When rotating mechanism is pressed down, upper hole portion has departed from lateral pin, rotating mechanism is to be only enclosed within on motor shaft, rotation that can drive motor axle during manual operation rotating mechanism, get final product independent rotation, resistance while having reduced manual divide-shut brake, deciliter action that makes manually to complete circuit breaker is lighter, and reduces between parts the wearing and tearing because resistance produces greatly.
Accompanying drawing explanation
Fig. 1 is the vertical view of the utility model pivot pin separating mechanism.
Fig. 2 is the cooperation cutaway view of the utility model motor shaft, rotating mechanism, spring.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, be the specific embodiment of the pivot pin separating mechanism of utility model automatic change-over.This embodiment comprises motor shaft 1, be arranged on lateral pin 2 on motor shaft 1, be set in the rotating mechanism 3 on motor shaft 1, the lower hole portion 32 that the endoporus of rotating mechanism 3 has the upper hole portion 31 that matches with lateral pin 2 shapes and matches with motor shaft 1 shape; When upper hole portion 31 is positioned at lateral pin 2 places and matches, motor and rotating mechanism 3 interlocks; When pressing down rotating mechanism 3, upper hole portion 31 departs from lateral pins 2, and rotating mechanism 3 can rotate alone around motor shaft 1.Lateral pin 2 is set on motor shaft 1, the upper hole portion 31 match is set on rotating mechanism 3, when upper hole portion 31 is stuck in lateral pin 2 and matches with it, motor rotarily drives rotating mechanism 3 and rotates, and realization is carried out the operation of divide-shut brake to circuit breaker automatically; When rotating mechanism 3 is pressed down, upper hole portion 31 has departed from lateral pin 2, rotating mechanism 3 is only that the structure by upper hole portion 31 and lower hole portion 32 is enclosed within on motor shaft 1, rotation that can drive motor axle 1 during manual operation rotating mechanism 3, can depart from motor independent rotation, resistance while having reduced manual divide-shut brake, deciliter action that makes manually to complete circuit breaker is lighter, and reduces between parts the wearing and tearing because resistance produces greatly.
The fit system that rotating mechanism 3 of the present utility model and motor shaft 1 can fasten by upper hole portion 31 and lateral pin 2 is fixed, and by be arranged on that rotary handle on rotating mechanism 3 presses down rotating mechanism 3 or on carry.As a kind of improved embodiment, on motor shaft 1, be arranged with spring 4, spring 4 is arranged on the below of rotating mechanism 3.Power by being assemblied in rotating mechanism 3 lower springs 4 is stuck in lateral pin 2 places by upper hole portion 31 tops of rotating mechanism 3, while making electric machine rotation, motor shaft 1 and lateral pin 2 driven rotary mechanisms 3 rotate, by rotating mechanism 3, drive the toggle mechanism of left and right to rotate, complete the on/off switch of circuit breaker when reaching electric machine rotation.By being assemblied in rotary handle on rotating mechanism 3 to pressing down rotating mechanism 3, the spring 4 that rotating mechanism arranges for 3 times, after Compress Spring 4, makes hole portion 31 separated with lateral pin 2, departs from the binding force of motor while making hand rotation rotating mechanism 3 completely; When decontroling rotary handle, rotating mechanism 3 upwards promotes to make upper hole portion 31 tops to be stuck in lateral pin 2 places by the elastic force of spring 4.
As a kind of improved embodiment, the bottom of rotating mechanism 3 has the cylindrical groove 5 for retainer spring 4.The design of cylindrical groove 5 guarantees the stable cooperation of spring 4 and rotating mechanism 3 and moves up and down, reasonable integral structure.
As a kind of improved embodiment, the top of rotating mechanism 3 has for the boss 6 of rotary handle is installed.The design of boss 6 is convenient to install and coordinate with rotary handle, rotary handle and rotating mechanism 3 Stability Analysis of Structures.
As a kind of improved embodiment, lateral pin 2 can adopt integrated design with motor shaft 1, sound construction, and rotary drive is reliable.
As a kind of improved embodiment, lateral pin 2 can adopt separate design with motor shaft 1, and lateral pin 2 is arranged in the pin-and-hole on motor shaft 1.Separated structure is convenient to processing, and cost is lower.
