Background

Switches are used to open a circuit, interrupt a current, or flow it to other electronic components of a circuit, the most common being electromechanical devices that are operated.

Existing switches are typically mechanical push-button switches, which typically have only two states:

firstly, directly conducting the corresponding circuit;

and secondly, directly closing the corresponding circuit.

In some large electrical devices, a switch is required to gradually slow down the supply voltage until the power is cut off. The existing common switch can not be realized, so that the applicability of the switch is poor.

The rotating disc type triggering jacking mechanism creatively drives the connecting shaft to rotate through the driving piece, and the rotating disc is connected to the middle of the connecting shaft and is provided with the contact cylinder at the lower part.

The upper end of the ejector rod assembly is always abutted against the stirring part of the contact cylinder, and the contact cylinder can push the ejector rod assembly along with the rotation of the turntable in the process.

That is to say, when the ejector pin subassembly supports and leans on the lowest of stirring portion, the ejector pin subassembly shifts up, and the ejector pin subassembly lower extreme is located the casing this moment.

Otherwise, when the ejector rod component is abutted against the highest position of the shifting part, the ejector rod component moves downwards, and the lower end of the ejector rod component extends out of the shell through the through hole at the moment.

The lower end of the push rod component extending out of the shell is stably contacted with a corresponding switch.

The push rod assembly gradually extends out of the shell, so that the switch can be gradually pressed, and the power supply voltage of the corresponding large-scale electric appliance can be changed after the switch is gradually pressed, so that the large-scale electric appliance can be gradually stopped.

In the rotating disc type triggering jacking mechanism, the rotating disc and the contact cylinder are of an integrated structure.

In the above rotating disc type triggering and jacking mechanism, the driving part is a motor, and a rotating shaft of the motor is fixedly connected with the connecting shaft.

In the rotating disc type triggering and jacking mechanism, a connecting plate which is transversely arranged is fixedly connected in the shell, and the middle part of the connecting shaft is arranged on the connecting plate in a penetrating way.

In the rotating disc type triggering and jacking mechanism, the jacking rod assembly comprises a jacking rod and a spring, the middle part of the jacking rod is arranged on the connecting plate in a penetrating mode, the spring is sleeved at the upper end of the jacking rod, two ends of the spring act on the jacking rod and the connecting plate respectively, and the upper end of the jacking rod is abutted against the shifting part under the elastic force of the spring.

The connection plate serves two purposes:

firstly, positioning a connecting shaft;

and secondly, positioning the ejector rod.

The ejector rod has the tendency of moving upwards under the action of the elastic force of the spring, and the upper end of the ejector rod is ensured to have the tendency of abutting against the poking part all the time.

In the rotating disc type triggering jacking mechanism, the upper end of the jacking rod is in threaded connection with a positioning nut, and two ends of the spring are respectively jacked on the positioning nut and the connecting plate.

The positioning nut has two functions:

firstly, after the upper end of the spring is blocked by the positioning nut, the upper end of the spring is limited;

after the position of the positioning nut is adjusted, the elasticity of the spring can be changed, and the applicability of the spring is improved.

In the rotating disc type triggering jacking mechanism, the lower end of the jacking rod is fixedly connected with a flexible contact pad.

In the rotating disc type triggering and jacking mechanism, the contact pad is made of rubber materials and is cylindrical, and the contact pad is sleeved at the lower end of the ejector rod.

The contact pad can avoid the ejector pin lower extreme to contact with the switch rigidity that corresponds.

In the above rotating disc type triggering and jacking mechanism, the upper end of the jacking rod is a spherical contact part.

The arrangement of the contact part can reduce the frictional resistance between the push rod and the toggle part.

Compared with the prior art, the rotating disc type triggering jacking mechanism has the advantages that the driving piece drives the rotating disc to rotate, so that the jacking rods can be gradually pushed, the corresponding switches can be gradually pressed after the jacking rods extend out of the shell, the switches can be stably and gradually pressed, and the stability of the mechanism is effectively improved.

Meanwhile, the turntable, the ejector rod assembly and the like are positioned in the shell, so that the structure is compact.
