Description

[0003] 1: single press operation button, this kind of button realizes switch or signal switching function through vertical pressing operation, is usually composed of spring reset mechanism and conductive contact, has the advantages of simple structure and low cost, is widely used in life. For example: ordinary power switch, mechanical equipment starting button, etc.

Although the rotating button can adjust the gear, when the device needs to be urgently turned off, the rotating operation is too slow and lacks immediate response capability.

[0009] 4. Insufficient reliability: in the design of traditional rotating buttons and pressing buttons, the cooperation between the mechanical structure and the conductive contact is relatively complex, and after long-term use, problems such as wear and poor contact may occur, leading to a decline in device control performance, so it is necessary to make further improvements.

[0055] Working principle:

[0056] When the user presses the valve rod 4 in the axial direction, the valve rod 4 drives the transmission shaft 5 inside it to move downward in the vertical direction. During the pressing process, the bottom of the valve rod 4 is provided with an upper ratchet wheel 41, and the upper end surface of the transmission shaft 5 is provided with a lower ratchet wheel 51, and the upper ratchet wheel 41 and the lower ratchet wheel 51 are pressed against each other to generate a rotating force to push the transmission shaft 5 to rotate; when the transmission shaft is pressed to a certain position, the transmission shaft rotates, so that the lower ratchet wheel 51 on it is buckled to the end surface of the driving ratchet wheel 35, thereby locking the transmission shaft in the pressed state. In addition, when the user presses, the return spring 52 is compressed to provide appropriate rebound force for the button, and after the user releases his hand, the valve rod pops up to reset. When the transmission shaft is pressed, the movable electrode plate 6 installed at the bottom of the transmission shaft 5 contacts the fixed electrode sheet 61 with the downward movement of the transmission shaft, thereby completing the conduction of the electrical signal.

[0057] The pressing operation realizes the closure of the circuit, and is suitable for scenes of switch, mode starting or emergency operation.

[0058] When the user presses the valve stem again, the valve stem moves downward, the upper ratchet 41 at the bottom of the valve stem extrudes the lower ratchet 51, and the lower ratchet is separated from the drive ratchet 35, under the action of the rotating force, the transmission shaft rotates by a certain angle, so that the lower ratchet reenters the vertical guide groove 34, and the valve stem and the transmission shaft are lifted upward under the action of the top spring 14 to reset, so that the movable electrode plate is lifted and reset, and the power supply of the push button switch is turned off.

[0059] When the user rotates the valve stem 4 along the horizontal plane, the valve stem 4 is matched with the vertical guide groove 34 in the turntable 3 through the upper guide table 42 on the outer cylindrical surface of the valve stem 4, the turntable 3 is driven to rotate, and gear selection or parameter adjustment is realized.
