[0026] A preferred embodiment of a combined switch knob structure provided by the utility model is as follows: Figure 1-10As shown, it includes a handle 1 with an overall hollow structure and a handle head 12 fixedly connected to the end of the handle 1. The handle 1 can be a split structure. A knob groove 13 is provided on the side wall of the handle 1. A knob assembly 2 is provided inside the handle 1. The knob assembly 2 includes a knob mold shell 21 and a knob integrated cover 25. The knob mold shell 21 is rotatably connected to the knob integrated cover 25. A knob 26 is provided on the outer wall of the knob integrated cover 25. The knob 26 extends out of the knob groove 13 to the outside of the handle 1 for easy operation.

[0027] The knob mold shell 21 includes a rotating shaft hole 22 arranged inside the knob mold shell 21, and the knob integrated cover 25 includes a limiting shaft body 28. The rotating shaft hole 22 and the limiting shaft body 28 are both inverted cone structures. The limiting shaft body 28 can be snapped and placed in the rotating shaft hole 22 without affecting the rotation of the knob integrated cover 25 relative to the knob mold shell 21. After the knob assembly 2 is installed in the handle 1, the two ends of the limiting shaft body 28 are respectively close to the upper and lower inner walls of the handle 1, and the close distance is between 0-3mm, and the specific close distance can be 1mm, so that the upper and lower ends of the knob integrated cover 25 are limited, avoiding the jitter caused by the excessive size of the rotating area of ​​the knob integrated cover 25, thereby causing the knob operation to be stuck, and avoiding the situation where the two end faces of the handle 1 are stressed and concave and deformed, thereby ensuring the size stability of the entire handle 1.

[0028] Four positioning blocks 211 are symmetrically arranged on the upper and lower end surfaces of the inner cavity of the handle 1 , and each positioning block 211 is located on both sides of the knob groove 13 close to the inner cavity end surface of the handle 1 , and further, is located at the four corners of the knob groove 13 .

[0029] While the positioning block 211 plays a role in installing and positioning the knob integrated cover 25, the positioning blocks 211 located at the two end points of the knob 26 for adjustment effectively improve the problem of the knob integrated cover 25 shaking up and down, so that the shaking amplitude of the knob integrated cover 25 is limited, thereby enhancing the overall stability of the knob assembly 2.

[0030] Furthermore, the knob mold shell 21 also includes a storage cavity shell 23, which extends out of the outer wall of the knob mold shell 21, and the part of the storage cavity shell 23 extending out of the outer wall of the knob mold shell 21 is provided with a toggle stop groove 24, and the inner wall of the knob integrated cover 25 is provided with a stop cam 27 adapted to the toggle stop groove 24, which plays a certain installation and positioning role for the knob integrated cover 25.

[0031] A return spring 29 is provided in the inner cavity of the storage cavity shell 23, one end of the return spring 29 is fixedly connected to the bottom of the inner cavity of the storage cavity shell 23, and the other end of the return spring 29 is fixedly connected to a steel ball 210, the outer surface of the steel ball 210 abuts against the stop cam 27, and at the same time, the return spring 29 transmits elastic support to the knob integrated cover 25, so that the knob integrated cover 25 is subjected to the squeezing force of the return spring 29 during the toggling process, thereby ensuring the stability of the knob integrated cover 25 when it is toggled, and the steel ball 210 is located inside the toggling stop groove 24 to avoid falling off.

[0032] Specifically, when the knob 26 is rotated, the knob 26 drives the stop cam 27 provided on the inner wall of the knob integrated cover 25 to move and squeeze the steel ball 210, so that the steel ball 210 squeezes the reset spring 29 in the stop groove 24. The elastic force of the reset spring is cleverly utilized to make the knob integrated cover 25 be subjected to the squeezing force of the reset spring 29 during the toggling process, thereby tightening the knob integrated cover 25 made of plastic, thereby increasing the toggling feel and reducing the shaking of the knob integrated cover 25 in the inner and outer directions relative to the handle 1. At the same time, by designing a positioning block 211 on the knob groove 13 as an auxiliary positioning design on the handle 1, the upper limit of the knob shaking amount is reduced, the shaking defect of the knob 26 is improved, and the overall operating feel of the combination switch is improved.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
