Embodiment Construction

[0048] Please refer to Figure 1 to Figure 8 As shown, it shows the specific structure of the preferred embodiment of the present invention, including a transparent cover 10, a knob 20, a fixed cover 30, a button 40, a pressure rod 50, a fixed seat 60, a circuit board 70, and a first switch 71 , the second switch 72 and the lower cover 80.

[0049] The transparent cover 10 is arranged above the button 40 , the transparent cover 10 can protect the button 40 , and people can also see the light emitted by the internal light guide column 90 through the transparent cover 10 .

[0050] The knob 20 is rotatably arranged on the fixing seat 60, and the knob 20 can only rotate around the central axis, and cannot move longitudinally and laterally.

[0051] The lower surface of the knob 20 is protruded with an annular outer wall 21 and an inner wall 22, the lower surface of the inner wall 22 is protruded with a pressing protrusion 221, and an annular accommodation is formed between the o...

Abstract

The invention discloses a one-button starting switch, comprising a knob, a button, a compression rod, a fixing base, and a first switch and a second switch which are located on the fixing base. The knob is rotationally set on the fixing base. The compression rod is located on the first switch in a floating mode. Through rotation of the knob, the compression rod is triggered to compress down, and the first switch is turned on. The button is located in a middle part of the knob in a self-resetting mode. A limiting part for locking the button is set on the knob. Through setting of the knob on thestarting switch, in an initial state, the knob is rotated first, after the knob is rotated, the compression rod is triggered, the compression rod is enabled to compress down, the first switch is turned on, then the button is unlocked, the unlocked button is allowed to be pressed down to turn on the second switch, and after the second switch is turned on, the whole starting switch is turned on. Under an effect of the knob, two layers of protection is carried out on the starting switch, so wrong starting resulting from misoperation of a worker or the fact that the switch is touched by a foreignobject can be effectively prevented, and production safety is improved.

Description

technical field [0001] The invention relates to the technology in the field of engineering machinery, in particular to a one-button start switch. Background technique [0002] Construction machinery is an important part of the equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. In all countries in the world, the title of this industry is basically the same, among which the United States and the United Kingdom are called construction machinery and equipment, Germany is called construction machinery and equipment, Russia is called construction and road construction machinery, and Japan is called construction machinery. In China, some products are also called construction machinery, while the mecha...
