The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.

The rotary switch device is used for meeting the requirements of shielding holes 9 with related functions formed on related products and protecting internal parts of the related products. The relevant functional hole 9 can be opened and closed by operating a rotary switching device. When the associated product is not in use, the closing of the aperture 9 by the rotary switch means protects the internal components and prevents the ingress of foreign matter.

The rotary switch device in the related art adopts equipment such as a motor to drive, occupies larger space, has a complex structure, is unfavorable for manufacturing and assembly, and has higher manufacturing cost.

To this end, as shown in fig. 1 to 6, an aspect of the present disclosure provides a rotary switching device including a fixed member 1, a pushing member 2, a stopper 3, an elastic member 4, and a rotating member 5.

The elastic piece 4 is connected to the limiting piece 3, one end, away from the limiting piece 3, of the elastic piece 4 is connected with the fixing component 1, the elastic piece 4 is used for pushing the limiting piece 3 to be connected with the pushing piece 2 to limit the pushing piece 2, the pushing piece 2 and the rotating piece 5 are both rotationally connected to the fixing component 1, and the rotating piece 5 is in transmission connection with the pushing piece 2 so that the rotating piece 5 drives the pushing piece 2 to rotate.

The rotating member 5 has a first position and a second position, the pushing member 2 and the limiting member 3 cooperate to limit the rotating member 5 to be in the first position or the second position, the rotating member 5 is in the first position, the rotating member 5 is in an open state, the rotating member 5 is in the second position, and the rotating member 5 is in a closed state.

Wherein, the rotation piece 5 can open the hole 9 or close the hole 9 in the rotation process, when the rotation piece 5 opens the hole 9, then the rotation piece 5 is in an open state, when the rotation piece 5 closes the hole 9, then the rotation piece 5 is in a closed state.

When the pushing piece 2 pushes the limiting piece 3, the limiting piece 3 presses the elastic piece 4, the elastic piece 4 elastically deforms, and the elastic piece 4 can push the limiting piece 3 to be connected with the pushing piece 2 when being recovered, so that the pushing piece 2 is limited, and the rotating piece 5 is kept at the first position or the second position.

Wherein the fixing member 1 can mount the pushing member 2, the limiting member 3, the elastic member 4 and the rotating member 5, and the fixing member 1 can be connected to the related products.

In the above technical solution, the elastic member 4 and the limiting member 3 are provided to limit the pushing member 2, so that the state of the pushing member 2 is limited, and the state of the rotating member 5 is also limited when the pushing member 2 is limited by synchronous rotation of the pushing member 2 and the rotating member 5, so that the rotating member 5 can be kept at the first position or the second position, and the rotating member 5 can be kept to open or close the related hole 9, so that the related hole 9 can be opened or the related hole 9 can be closed as required. In addition, as the rotating piece 5 and the pushing piece 2 synchronously rotate, the rotating piece 5 is operated to enable the pushing piece 2 to push the limiting piece 3, and the elastic piece 4 can reset the limiting piece 3, so that the related hole 9 can be conveniently opened or the related hole 9 can be conveniently closed through rotating operation. The rotary switch device does not need to be provided with a motor and other structures, simplifies the structure, has less used parts and small occupied space, is beneficial to production and assembly, and greatly reduces the manufacturing cost.

As shown in fig. 1 and 2, alternatively, in one embodiment of the present disclosure, the number of the limiting members 3 and the number of the elastic members 4 are two, the two limiting members 3 are located at two sides of the pushing member 2, each limiting member 3 includes a limiting head 301 and a connecting rod 302 formed on the limiting head 301, the limiting head 301 is connected with the pushing member 2, the elastic member 4 is connected to the connecting rod 302, a first end of the elastic member 4 is connected with the limiting head 301, and a second end of the elastic member 4 is connected with the fixing member 1.

The two limiting members 3 can respectively generate extrusion effects on two sides of the pushing member 2, which is more beneficial to the state limitation of the pushing member 2, so that the rotating member 5 is better kept at the first position or the second position, in other words, the rotating member 5 can better keep an open state or a closed state. And the two elastic pieces 4 can respectively drive the two limiting pieces 3 to reset.

It can be understood that when the rotation member 5 drives the pushing member 2 to rotate, the pushing member 2 can push the two limiting members 3 to move in a direction away from the pushing member 2.

The connecting rod 302 is located at one side of the limiting head 301 away from the pushing piece 2, and the elastic piece 4 is connected to the connecting rod 302, so that the position of the elastic piece 4 can be fixed. It can be understood that when the limiting head 301 is pressed, the first end of the elastic element 4 is pressed by the limiting head 301, and the second end of the elastic element 4 is supported by the fixing component 1, so that the elastic element 4 is elastically deformed.

Alternatively, in some examples, the elastic member 4 may be a spring that is sleeved around the connecting rod 302. In other examples, the elastic member 4 may be an elastic metal sheet or an elastic polymer material.

Optionally, in other embodiments of the present disclosure, the limiting member 3 includes a limiting holder, and the limiting holder is provided with a limiting groove, where the limiting groove is used to accommodate the pushing member 2, and the shape of the limiting groove is consistent with the shape of the pushing member 2.

As shown in fig. 2, optionally, in one embodiment of the present disclosure, the pushing member 2 includes a pushing head 201 and a pushing rotating shaft 202 formed on the pushing head 201, a first mounting hole 103 is formed on the fixing component 1, one end of the pushing rotating shaft 202 away from the pushing head 201 is rotatably connected to the first mounting hole 103, and the pushing head 201 is connected to the limiting head 301.

The pushing head 201 is used for pushing the limiting piece 3, the limiting effect of the limiting piece 3 also acts on the pushing head 201, and the pushing shaft 202 and the first mounting hole 103 are matched to facilitate the pushing head 201 to rotate along with the rotating piece 5. In some examples, the first end of the pushing shaft 202 is integrally formed with the axial center of the pushing head 201, and the second end of the pushing shaft 202 is turned into the first mounting hole 103.

Alternatively, in another embodiment of the present disclosure, the pushing member 2 may be provided with a hole, the fixing member 1 is provided with a rotating rod, the pushing member 2 is connected to the rotating rod through the hole, and the pushing member 2 can rotate around the axis of the rotating rod.

As shown in fig. 2, alternatively, in one embodiment of the present disclosure, an arc-shaped limiting groove 303 is formed at an end of the limiting head 301 near the pushing head 201, the pushing head 201 is snapped into the arc-shaped limiting groove 303, and the pushing head 201 is configured as a cam or an elliptic cylinder.

The arc limiting groove 303 can better extrude the pushing head 201, and limit the pushing head 201. It can be appreciated that the pushing head 201 rotates to generate a pushing action on the arc-shaped limiting groove 303, and the elastic member 4 generates a resetting action, so that the pushing head 201 can be clamped into the arc-shaped limiting groove 303 to realize limiting when rotating to a corresponding position.

Optionally, in some examples, the arcuate limit groove 303 is adapted to the shape of the pusher head 201, and when the pusher head 201 is rotated to the corresponding position, the outer wall of the pusher head 201 is in close contact with the groove wall of the arcuate limit groove 303.

It can be understood that when the rotating member 5 rotates to drive the pushing head 201 to rotate, the pushing head 201 continuously pushes and extrudes the limiting head 301 when the pushing head 201 rotates from 0 degree to 90 degrees, when the pushing head 201 rotates to 90 degrees, the generated pushing and extrusion effect is maximum, and when the rotation angle of the pushing head 201 is greater than 90 degrees, the pushing and extrusion effect of the pushing head 201 on the limiting head 301 is reduced, and when the limiting head 301 extrudes the pushing head 201 under the action of the elastic member 4, the pushing head 201 rotates to 180 degrees rapidly, and at the moment, the rotating member 5 can be switched from the first position to the second position. At the same time, the rotating member 5 is kept in the second position due to the elastic action of the elastic member 4. When the rotating member 5 is continuously rotated, the pushing head 201 is driven to continuously rotate, the pushing head 201 continuously rotates from 180 degrees until 360 degrees, the limiting head 301 extrudes the pushing head 201 under the action of the elastic member 4, and at this time, the rotating member 5 can be switched from the second position to the first position and kept at the first position.

The rotating member 5 of the rotary switch device can not be limited by the rotation direction, can rotate forward or reversely, and is very convenient to use.

Alternatively, in other embodiments, the pushing head 201 may be configured in other shapes, as long as the pushing action on the stopper 3 during rotation can be generated.

Wherein, the rotation piece 5 of the disc-shaped structure can shade and close the hole 9 when rotating to the position of the hole 9. Through the eccentric rotating shaft 501, when the rotating piece 5 rotates around the axis of the eccentric rotating shaft 501, the rotating piece can rotate to the position of the hole 9 or the position away from the hole 9, so that the hole 9 is opened or closed.

It is understood that the eccentric rotation shaft 501 means that a rotation shaft is formed at a position away from the axis of the rotation member 5, and when the rotation member 5 rotates, the eccentric rotation shaft 501 rotates together, and the eccentric rotation shaft 501 rotates in the second mounting hole 104.

By this arrangement, the pushing member 2 and the eccentric rotation shaft 501 can be rotated synchronously. The cross-sectional shape of the shaft and the cross-sectional shape of the hole may not be limited, as long as the transmission portion 502 and the adapter portion 204 are not rotated relative to each other. Of course, in other embodiments, the transmission portion 502 and the adapting portion 204 may be gears, and the transmission portion 502 and the adapting portion 204 may be meshed, so that transmission may be implemented.
