[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] This embodiment is a high-strength gas stove switch shaft.
[0025] As Figures 1-4 shown, it includes a switch shaft 1, an installation hole 2 is opened in the lower part of the outer surface of one side of the switch shaft 1, an insertion slot 4 is opened in the middle of the outer surface of the upper end of the switch shaft 1, a strengthening limit member 3 is arranged on the outer wall of the upper part of the switch shaft 1, the strengthening limit member 3 includes an outer ring body 5, a bottom limit ring 6, a compression spring 7 and a movable limit ring 8, and the bottom limit ring 6 is located on the outer wall of the upper part of the switch shaft 1.
[0026] The inner wall of the bottom limiting ring 6 is fixedly connected to the outer wall of the upper part of the switch shaft 1; the bottom limiting ring 6 is fixedly installed at the bottom of the inner cavity of the outer ring body 5; the compression spring 7 is located inside the outer ring body 5, and the lower end of the movable limiting ring 8 extends into the inside of the outer ring body 5; the outer surface of the lower end of the compression spring 7 is fixedly connected to the upper outer surface of the bottom limiting ring 6, the outer surface of the upper end of the compression spring 7 is fixedly connected to the lower outer surface of the movable limiting ring 8, the outer wall of the movable limiting ring 8 is slidably connected to the inner wall of the outer ring body 5, and the lower outer surface of the movable limiting ring 8 is elastically connected to the upper outer surface of the bottom limiting ring 6 through the compression spring 7; when the compression spring 7 is in a normal state, the movable limiting ring 8 is sleeved on the outer wall of the upper part of the switch shaft 1, and the insertion slot 4 is located inside the movable limiting ring 8.
[0027] It should be noted that the present utility model is a high-strength gas stove switch shaft. The provided strengthening limiting member 3, when installing an external knob switch, first squeezes the movable limiting ring 8 to release the limit on the top of the switch shaft 1. After the movable limiting ring 8 is squeezed, it squeezes the compression spring 7 along the inner wall of the outer ring body 5. When the movable limiting ring 8 is pressed, the insertion block in the knob switch is inserted into the insertion slot 4. At this time, without the limit of the movable limiting ring 8, the area of the insertion slot 4 can increase when the insertion block of the knob switch is inserted, making the installation of the knob switch more convenient. After the knob switch is installed, release the movable limiting ring 8, and the compression spring 7 restores the movable limiting ring 8 to its original position. And manually push the movable limiting ring 8 upward to limit the movable limiting ring 8 on the outer wall of the top of the switch shaft 1. Through the limit of the movable limiting ring 8, the space of the insertion slot 4 can be prevented from continuing to increase, playing a strengthening role, thereby improving the service life of the switch shaft 1.
