Description

Technical Field

[0001] This utility model relates to the field of changeover switch technology, specifically a reliable changeover switch. Background Technology

[0002] A changeover switch is a control appliance that can be manually or electrically operated to switch between multiple circuits or operating states, realize the switching of different power supplies, loads or circuits, and switch different working modes in the equipment. Some switches have position indicators to intuitively display the current working status. One type is a two-section changeover switch, which consists of a panel, a throttle, and two sections.

[0003] The aforementioned and existing related technologies often have the following drawbacks: Changeover switches are widely used in industrial control, outdoor operations, and other scenarios. Especially in environments without visual feedback, such as at night or underground, the requirements for operational accuracy and safety are significant. Changeover switches mostly use a locking mechanism, which can easily lead to excessive rotation of the handle by operators in the dark due to tactile deviations. This can cause wear on internal contacts, gear breakage, and other structural damage. At the same time, they are not adapted to blind operation requirements and lack a tactile feedback mechanism, making it difficult to perceive the gear switching status through tactile feedback. This can easily lead to problems such as accidental gear switching or poor contact.

[0004] Therefore, we propose a reliable changeover switch. Utility Model Content

[0011] The effect achieved by the above components is that the rotating ball drives the screw to rotate, and the ball achieves the effect of rapidly rotating the screw.

[0012] Preferably, two magnets are fixedly connected to the side of the frame away from the panel, and the inner wall of the magnets is attracted to the positioning rod.

[0013] The effect achieved by the above components is that the positioning rod slides to the inner wall of the magnet and is attracted to it, and the magnet can temporarily limit the throttle.

[0016] Preferably, the shield is an acrylic shield, and a counterweight is fixedly connected to the lower surface of the shield.

[0017] The effect achieved by the above components is that the counterweights effectively prevent the shield from swinging by using their own weight.

[0018] Preferably, a rocker arm is fixedly connected to the side of the shield away from the panel, and the rocker arm is inclined on one side of the shield.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 and Figure 2This utility model provides a technical solution: a reliable changeover switch, including a panel 1, a handle 2 rotatably connected to one side of the panel 1, and two sections 3 fixedly connected to the side of the panel 1 away from the handle 2. The handle 2 is fixedly connected to the inner wall of the two sections 3. A positioning structure 4 is provided on the side of the panel 1 near the handle 2, which improves the adjustment accuracy of the changeover switch handle 2, thereby avoiding the problem of jamming and positioning of the changeover switch. In the dark, the operator may cause excessive rotation of the handle due to tactile deviation, resulting in wear of internal contacts, gear breakage, and other structural damage. A shielding structure 5 is provided on the upper surface of the panel 1, which shields the handle 2. By shielding the exposed handle 2 of the rotary switch, it effectively prevents unauthorized personnel from touching it and can also prevent foreign objects from contacting it to a certain extent, thus improving the safety of the device.

[0030] The specific settings and functions of its positioning structure 4 and shielding structure 5 will be explained below.

[0031] like Figure 2 and Figure 3 As shown, the positioning structure 4 includes two fixing plates 41. One side of each fixing plate 41 is fixedly connected to the panel 1. A frame 42 is fixedly connected to the inner wall of the two fixing plates 41. A Z-shaped plate 43 is fixedly connected to the surface of the throttle 2. A positioning rod 44 is fixedly connected to the lower surface of the Z-shaped plate 43. The arc surface of the positioning rod 44 is slidably connected to the inner wall of the frame 42. A screw 45 is threaded through the side of the Z-shaped plate 43 away from the panel 1. A connecting strip 46 is fixedly connected to the side of the panel 1 near the frame 42. A retaining frame 47 is fixedly connected to both sides of the connecting strip 46. The arc surface of the screw 45 is slidably connected to the inner wall of the retaining frame 47. The screw 45 is inserted into the retaining frame 47 through the Z-shaped rod. The screw 45 plays the role of stabilizing and limiting the rotation of the throttle 2.

[0032] A ball 48 is fixedly connected to the end of the screw 45 away from the frame 47. The arc surface of the ball 48 has a groove. Rotating the ball 48 drives the screw 45 to rotate, and the ball 48 achieves the effect of rapidly rotating the screw 45. Two magnets 49 are fixedly connected to the side of the frame 42 away from the panel 1. The inner wall of the magnet 49 is attracted to the positioning rod 44. The positioning rod 44 slides to the inner wall of the magnet 49 and is attracted to it. The magnet 49 serves to temporarily limit the throttle 2.

[0033] like Figure 2 and Figure 3 as well as Figure 4As shown, the shielding structure 5 includes a U-shaped frame 51. The lower surface of the U-shaped frame 51 is fixedly connected to the panel 1. A rotating rod 52 is rotatably connected to the inner wall of the U-shaped frame 51. A shielding cover 53 is fixedly connected to the arc surface of the rotating rod 52. The handle 2 is located inside the shielding cover 53. The shielding cover 53 is an acrylic cover. A counterweight 55 is fixedly connected to the lower surface of the shielding cover 53. The counterweight 55 uses its own weight to effectively prevent the shielding cover 53 from swinging. A rocker 54 is fixedly connected to the side of the shielding cover 53 away from the panel 1. The rocker 54 is tilted on one side of the shielding cover 53. Pushing the tilted rocker 54 causes the shielding cover 53 to rotate. The rocker 54 achieves a better opening and closing effect for the heavier shielding cover 53.

[0034] Working principle: When adjusting the gear position in scenarios such as nighttime operation of underground equipment without visual feedback, the shield 53 is first opened through the shielding structure 5, exposing the throttle 2. The throttle 2 can then be rotated directly according to the desired gear position. The rotation of the throttle 2 drives the internal circuitry of the second section 3 via the panel 1 to switch gears. The Z-shaped plate 43 drives the screw 45 to rotate via the throttle 2. The positioning rod 44 slides on the inner wall of the frame 42 via the Z-shaped plate 43. Using the concentric circles of the frame 42 and the throttle 2, the positioning rod 44 contacts the side of the frame 42, and the throttle 2 is adjusted to the desired gear position. At this point, the throttle 2 cannot rotate further, and the positioning rod 44 then adheres to the inner wall of the magnet 49. The magnet 49 attracts the positioning rod 44 using its own magnetic force. Magnet 49 temporarily limits the rotation of the handle 2. Depending on the user's needs, the ball 48 can be rotated towards the side closer to the panel 1, allowing the ball 48 to quickly rotate the screw 45. The screw 45, through the ball 48 and with the help of the Z-shaped plate 43 and its own thread, is inserted into the retaining frame 47. The screw 45 stabilizes and limits the rotation of the handle 2, thus preventing the handle 2 from rotating. The frame 42 and the positioning rod 44 form a tactile feedback angle limiting structure to prevent excessive rotation from damaging the internal structure. This is user-friendly for blind operation. Furthermore, the screw 45 and magnet 49 achieve dual positioning to meet the requirements of high-precision switching and rapid mode switching in military equipment and medical emergency equipment, thereby improving the reliability and efficiency of operation in complex environments.

[0035] When it is necessary to turn the throttle 2, first turn the rocker 54 away from the panel 1. The rocker 54 can better open and close the heavier shield 53. The shield 53 drives the counterweight 55 to rotate through the rocker 54. The counterweight 55 uses its own weight to effectively prevent the shield 53 from swinging. The rotating rod 52 rotates on the inner wall of the U-shaped frame 51 with the help of the shield 53. After rotating to a certain angle, the throttle 2 is exposed by the opening and closing of the shield 53. At this time, the throttle 2 can be shifted.
