Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a rotary synchronous switch. Background Technology

[0002] Currently, the AC / DC control rotary switch structures on the market can only achieve single-corresponding control functions through one-to-one matching of rotary switches for AC and DC control. This is quite inconvenient when synchronous control of AC and DC is required.

[0003] Therefore, there is an urgent need to provide a rotary synchronization switch to overcome the above-mentioned defects. Utility Model Content

[0004] The main purpose of this utility model is to provide a rotary synchronous switch with a reasonable structural design that helps to achieve synchronous control of AC and DC circuits.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rotary synchronous switch is used for AC / DC synchronous control. It is engaged with the rotating shaft of a rotary switch. There is a through hole in the middle of the switch. The through hole has at least one locking structure that fits into the rotating shaft. When the rotating shaft rotates, the rotary synchronous switch rotates synchronously with the rotating shaft.

[0006] Preferably, the bayonet structure is in the shape of a groove.

[0007] Preferably, the groove is formed by recessing the sidewall of the through hole inward.

[0008] Preferably, the bayonet structure is in the shape of a boss.

[0009] Preferably, the boss is shaped to protrude from the sidewall of the through hole toward the center.

[0010] Preferably, the rotary synchronization switch is a cuboid shape with chamfered apex corners.

[0011] Preferably, a cylinder is formed at the center of the rotary synchronization switch, and the through hole is formed inside the cylinder.

[0012] Preferably, the cylinder protrudes beyond the height of the housing plate of the rotary synchronization switch, and the two ends of one diameter of the cylinder abut against the inner sidewall of the housing plate, and reinforcing ribs are formed from the outer sidewall of the cylinder to the inner sidewall of the housing plate in the other diameter direction perpendicular to the first diameter.

[0013] Preferably, the rotary synchronous switch is a cuboid shape with chamfered apex corners.

[0014] Preferably, the rotary synchronization switch has an axisymmetric structure.

[0015] This utility model relates to a rotary synchronous switch, which is used for AC / DC synchronous control. It is connected to the rotating shaft of a rotary switch by a through hole designed in the middle of the shaft. At least one snap-fit ​​structure is formed in the through hole. The snap-fit ​​structure matches the snap-fit ​​part on the rotating shaft, so that when the rotary switch rotates, it drives the rotating shaft, and then the rotating shaft drives the rotary synchronous switch to rotate. Thus, after applying this product, the function of AC / DC synchronous control can be realized. The product structure is simple and reasonable. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] It should be noted that when a component is referred to as "connected to" or "set on" another component, it can be directly on the other component or indirectly on that other component.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", and "front" are used interchangeably. The orientations or positional relationships indicated by terms such as "rear," "left," "right," "top," "bottom," "inner," and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly specified. "Several" means one or more, unless otherwise expressly specified.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Please see Figure 1 The rotary synchronous switch of this embodiment is used for AC / DC synchronous control and is snapped into the rotating shaft of the rotary switch. It has a through hole 1 in the middle part and at least one snap-fit ​​structure 2 that fits into the rotating shaft in the through hole 1. When the rotating shaft rotates, the rotary synchronous switch rotates synchronously with the rotating shaft.

[0024] In a preferred embodiment, the rotary synchronous switch is designed as a cuboid with chamfered apex corners, and it has an axisymmetric structure. This symmetrical structure helps improve the stability of the product when rotated under stress. The chamfered design allows the elastic element with terminal contacts mounted at the abutting end to move when the product is used in an AC / DC synchronous control rotary switch, resulting in low friction loss and high stability and performance during use. Specifically, a cylinder 3 is formed at the center of the rotary synchronous switch, and the through hole 1 is formed within the cylinder 3. The snap-fit ​​structure 2 in this embodiment is a groove shape; specifically, the groove shape is formed by recessing from the sidewall of the through hole 1. More specifically, the cylinder 3 protrudes beyond the height of the housing plate a1 of the rotary synchronous switch, and the two ends of one diameter of the cylinder 3 abut against the inner sidewall of the housing plate a1. A reinforcing rib a2 is formed from the outer sidewall of the cylinder 3 toward the inner sidewall of the housing plate a1 in the direction perpendicular to the diameter. The housing plate a1 forms a square cavity, and the cylinder 3 is formed in the cavity. This structural design facilitates the use of AC / DC rotary switches, improves the compactness of the structure, avoids interference with other components, and improves the stability of the product itself.

[0025] In some other preferred embodiments, the bayonet structure is in the shape of a boss (not shown in the figure). In this embodiment, the boss is formed by protruding from the side wall of the through hole toward the center.

[0026] In use, the rotating shaft passes through the through hole 1, and the engaging part on the rotating shaft engages with the bayonet structure. When the rotating shaft rotates, this rotary synchronous switch moves in conjunction with the shaft, and its apex angle drives the corresponding terminal contacts to achieve either a closed or open state, realizing the AC control function. Therefore, when this product is used for AC / DC synchronous control, it works in conjunction with the rotating shaft on the rotary switch to achieve synchronous control of AC and DC. The function of the rotating shaft controlling DC is an application of existing technology and will not be elaborated here.

[0027] The structural design of this product helps to achieve AC / DC synchronous control.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
