[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0025] like Figures 1 to 3 As shown, the utility model provides a rotary switch chassis structure, including a chassis 1 and an electrode sheet 2. In order to achieve the purpose of the utility model, the chassis 1 is provided with a positioning boss 11, and the electrode sheet 2 is provided with a sleeve clamping hole 20, and the sleeve clamping hole 20 is clamped on the positioning boss 11. In this way, the assembly and installation of the electrode sheet 2 can be achieved in one step, which greatly improves the production efficiency and helps to reduce the labor cost of a single product.

[0026] like Figures 1 to 4 As shown, the sleeve clamp hole 20 includes a sleeve hole 21 and a positioning spring 22 provided on the electrode sheet 2, and the elastic end of the positioning spring 22 is placed at the opening of the sleeve hole 21, the sleeve hole 21 is sleeved on the positioning convex column 11, and the positioning spring 22 elastically presses on the positioning convex column 11. In this way, the sleeve hole 21 generates a limiting force on the positioning convex column 11, and the positioning spring 22 generates an elastic pressing force on the positioning convex column 11 at the same time, and the sleeve clamping effect of the sleeve clamp hole 20 on the positioning convex column 11 is achieved by the sleeve of the sleeve hole 21 and the elastic pressing of the positioning spring 22.

[0027] As a preference, Figure 4 As shown, the set hole 21 includes an arc hole 211 and a rectangular hole 212. The arc hole 211 and the positioning spring piece 22 are respectively arranged at both ends of the rectangular hole 212. Preferably, the arc hole 211 is connected to the rectangular hole 212, and the diameter of the arc hole 211 is equal to the width of the rectangular hole 212. In this way, the length of the set hole 21 is larger, which is more conducive to fitting the set hole 21 on the positioning boss 11.

[0028] like Figure 4 As shown, the positioning spring piece 22 and the electrode sheet 2 are an integrated structure, so that when the set hole 21 is punched, a circular hole 211 and a rectangular hole 212 are formed on the electrode sheet 2, and the edge piece composed of the circular arc part and the rectangular part can be used as the positioning spring piece 22. This makes the preparation process of the electrode sheet 2 very simple, and does not require riveting, welding and other processes to fix the positioning spring piece 22 to the electrode sheet 2, nor does it need to make additional positioning spring pieces 22, which is conducive to controlling the production cost of the electrode sheet 2.

[0029] like Figures 1 to 3 As shown, there are multiple positioning bosses 11, each of which is arranged in a ring shape on the end surface of the chassis 1. A plurality of positioning bosses 11 can provide installation and positioning for multiple electrode sheets 2, wherein each electrode sheet 2 is provided with a sleeve clamping hole 20, and each sleeve clamping hole 20 is respectively clamped on the positioning boss 11, thereby forming a suitable rotary switch.

[0030] like Figures 1 to 3 As shown, in order to enable the electrode sheet 2 to be more firmly mounted on the chassis 1 , an insertion groove 12 is provided on the end surface of the chassis 1 .

[0031] like Figure 4 As shown, one end of the electrode sheet 2 is an insertion end 23, and the other end is a wiring end 24. The insertion end 23 is inserted into the insertion slot 12, and the wiring end 24 is placed outside the edge of the chassis 1. When installing the electrode sheet 2, first insert the insertion end 23 into the notch of the insertion slot 12. At this time, the rectangular hole 212 of the sleeve hole 21 is aligned with the positioning protrusion 11, and the electrode sheet 2 is pressed downward. The insertion end 23 slides into the insertion slot 12, and the arc hole 211 of the sleeve hole 21 is sleeved on the positioning protrusion 11. At the same time, the positioning spring 22 elastically presses on the positioning protrusion 11, so that the sleeve clamping hole 20 can clamp the positioning protrusion 11, and the installation and positioning of the electrode sheet 2 is realized. The insertion slot 12 is also provided with multiple electrode sheets 2 for insertion, and each electrode sheet 2 is inserted into each insertion slot 12 respectively, so that each electrode sheet 2 can be firmly installed and positioned.

[0032] like Figure 3 As shown, the chassis 1 is provided with an observation hole 14 penetrating the insertion slot 12. In this way, whether during the installation of the electrode sheet 2 or during quality inspection, it is possible to observe whether the electrode sheet 2 is installed in place through the observation hole 14, which helps to improve the product quality rate and ensure the quality of the product.

[0033] like Figures 1 to 3 As shown, the positioning boss 11 is placed at the edge of the chassis end surface. In this way, when installing the electrode sheet 2, the worker can put the index finger against the edge of the chassis 1 and press the terminal 24 of the electrode sheet 2 downward with the thumb, so that the clamp hole 20 can be accurately clamped on the positioning boss 11, thereby greatly improving the installation efficiency of the electrode sheet 2.

[0034] like Figures 1 to 3As shown, the end surface of the chassis 1 is also provided with an embedding groove 13 for embedding the electrode sheet 2, and the positioning protrusion 11 is arranged in the embedding groove 13. In this way, the electrode sheet 2 is limited by the embedding groove 13, which can effectively prevent the electrode sheet 2 from shaking left and right, which is conducive to increasing the stability and reliability of the chassis structure. There are also multiple embedding grooves 13, and each positioning protrusion 11 is respectively arranged in each embedding groove 13, so that each electrode sheet 2 is also limited by each embedding groove 13.

[0035] As a preference, Figure 2 , Figure 3 , Figure 7 As shown, one end of the embedding groove 13 is connected to the insertion groove 12, and the other end of the embedding groove 13 extends to the edge of the end surface of the chassis 1. In this way, the electrode sheet 2 is completely embedded in the embedding groove 13, which can more effectively prevent the electrode sheet 2 from shaking left and right. At the same time, the upper surface of the electrode sheet 2 is flush with the end surface of the chassis 1, which helps the conductive sheet 5 of the rotary switch to slide more smoothly on the chassis structure, and the hand feel is better when used.

[0036] like Figure 3 As shown, the positioning boss 11 is a cone structure, and the top diameter of the positioning boss 11 is smaller than the diameter of the set hole 21. In this way, when the set hole 21 is set on the positioning boss 11 from top to bottom, it is easier to insert it into the positioning boss 11, thereby improving production efficiency. Furthermore, the diameter of the arc hole 211 is equal to the diameter of the bottom end of the positioning boss 11, so that the arc hole 211 can more tightly cover the positioning boss 11, making the positioning of the electrode sheet 2 more stable.

[0037] like Figures 4 to 7 As shown, the rotary switch chassis structure further includes a housing 3, which covers the chassis 1, and the chassis 1 and the housing 3 are assembled together by screws 6. The housing 3 can play a shielding and protective role, which can not only improve the safety of use, but also reduce the aging speed, thereby helping to prolong the service life.

[0038] like Figure 6 , Figure 7 As shown, a rotating rod 4 is arranged between the housing 3 and the chassis 1, and a conductive sheet 5 is arranged at the bottom end of the rotating rod 4. In order to achieve gear adjustment, the utility model adopts 4 electrode sheets 2, of which one electrode sheet is a common electrode sheet 26, and the other three electrode sheets are gear electrode sheets 25. The three gear electrode sheets 25 and the common electrode sheet 26 are arranged on the left half and the right half of the chassis 1 respectively.

[0039] like Figure 4 , Figure 5 , Figure 7As shown, the shift electrode sheet 25 has a contact surface 27, and the common electrode sheet 26 has an arc-shaped contact portion 28. One end of the conductive sheet 5 contacts the arc-shaped contact portion 28 of the common electrode sheet 26, and the other end of the conductive sheet 5 contacts the contact surface 27 of the shift electrode sheet 25. When in use, the rotating rod 4 drives the conductive sheet 5 to rotate, and one end of the conductive sheet 5 slides in contact with the arc-shaped contact portion 28 of the common electrode sheet 26, and the other end slides in contact with the contact surfaces 27 of the three shift electrode sheets 25 in sequence, so as to adjust the shift position.
