Description

Technical Field

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

[0002] A rotary switch is a type of switch that uses a rotating handle to control the opening and closing of the main contacts. Traditional rotary switches can only control the action of one or a few actuators at a time, and cannot switch between controlling one or a few actuators, which limits their use in applications requiring precise control. Utility Model Content

[0003] The main objective of this invention is to provide a rotary switch device to solve the problem in the prior art that rotary switches cannot switch between controlling one or more actuators.

[0004] To achieve the above objectives, this utility model provides a switch rotation device, including an outer casing and a rotating column movably connected inside the outer casing. The inner casing has multiple points evenly distributed therein; one of these points is a blank stop position, and the remaining points are provided with protruding elastic contacts. The rotating column has four contact layers from top to bottom; each contact layer has a recessed groove contact for contacting the elastic contacts. The uppermost contact layer has one groove contact, and the number of groove contacts on the lowermost contact layer is the same as the number of elastic contacts. The sum of the number of groove contacts in the middle two layers is equal to the number of elastic contacts.

[0005] Furthermore, grooves are provided between adjacent contact layers, and an elastic locking rod is movably connected inside the outer sleeve, located below the elastic contact, for engaging with the grooves.

[0006] Furthermore, the rotating column has a cavity inside, and a fixed shaft is located inside the cavity. The top of the fixed shaft is fixedly connected to an elastic contact for contacting the groove contact point.

[0007] Furthermore, the flexible contact is connected to one end of a lead wire, and the other end of the lead wire is located under the outer casing.

[0008] Furthermore, a handle is fixedly connected to the top of the rotating column.

[0009] This invention features four contact layers, allowing switching between them to control a single actuator, several actuators, or all actuators individually, thus enabling its use in various application scenarios. Attached Figure Description

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 4 As shown, according to an embodiment of the present invention, a switch rotation device is provided, including an outer sleeve 2 and a rotating column 1 movably connected inside the outer sleeve 2. The inner sleeve 2 has 12 points evenly distributed inside it; one of these points is a blank stop position 9, and the remaining points are provided with protruding elastic contacts 3. The inner sleeve 2 has a mounting groove, and the elastic contacts 3 are movably connected in the mounting groove. The rotating column 1 has four layers of contact from top to bottom; each contact layer has a recessed groove contact 4 for contacting the elastic contacts 3. The uppermost contact layer has one groove contact 4, and the number of groove contacts 4 on the lowermost contact layer is the same as the number of elastic contacts 3. The middle two layers have five and six groove contacts 4 respectively. The groove contacts 4 of the middle two layers are staggered and used to control different actuators.

[0018] A groove 5 is provided between adjacent contact layers. An elastic locking rod 6 is movably connected inside the outer jacket 2 at a position below the elastic contact 3 for engaging with the groove 5. A locking groove is provided inside the outer jacket 2, and the elastic locking rod 6 is movably connected inside the locking groove.

[0019] The rotating column 1 has a cavity 101 inside, and a fixed shaft 7 is provided inside the cavity 101. The top of the fixed shaft 7 is fixedly connected to an elastic contact 11 for contacting the groove contact 4.

[0020] The flexible contact 3 is connected to one end of the lead wire 8, and the other end of the lead wire 8 is located below the outer casing 2; the lead wire 8 is used to electrically connect with different actuators, thereby controlling the action of the actuators.

[0021] A handle 10 is fixedly connected to the top of the rotating column 1; the handle makes it easy to hold.

[0022] The rotating column 1 has four contact layers. By pushing and pulling the rotating column 1, it is possible to switch between multiple layers. When the top contact layer of the rotating column 1 is aligned with the elastic contact 3, the rotating column 1 can control the action of a single actuator. When the bottom contact layer of the rotating column 1 is aligned with the elastic contact 3, the rotating column 1 can control the action of 11 actuators. When the middle two contact layers of the rotating column 1 are aligned with the elastic contact 3, the rotating column 1 can control the action of 5 or 6 actuators.

[0023] This embodiment can control a single actuator, several actuators, or all actuators separately, thus enabling its use in a variety of application scenarios.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
