Specifically, the switching mechanism includes a fixing bracket 100 for fixing the transmission assembly 300 and the rotating shaft 200 to the rotating member 400, the rotating shaft 200 for enabling the rotating member 400 to rotate, and the transmission assembly 300 for adjusting the relative position of the rotating shaft 200 and the rotating member 400. The other end of the rotating shaft 200 is connected to the transmission assembly 300, and the rotating shaft 200 is displaced relative to the fixing frame 100 during the rotation process, so that the distance between the rotating shaft 200 and the side of the rotating member 400 is changed. In actual use, the fixing frame 100 fixes the transmission assembly 300 on the rotating member 400. When the rotating member 400 rotates, the transmission assembly 300 drives the rotating shaft 200 to rotate, and the rotating shaft 200 moves towards the side edge close to the rotating member 400, so that the distance between the rotating shaft 200 and the side edge of the rotating member 400 is reduced, and the problem that the opening angle of the rotating member 400 is easily limited is further solved. When the rotating member 400 is closed, the transmission assembly 300 drives the rotating shaft 200 to rotate, and the rotating shaft 200 moves away from the side edge of the rotating member 400, so that the distance between the rotating shaft 200 and the side edge of the rotating member 400 is restored to the sealing position. By adopting the switch mechanism provided by the application, the problem that the rotation angle of the rotating part 400 is easily limited in the prior art is solved, and then the rotation of the rotating part 400 is relatively easier.

In a particular embodiment, drive assembly 300 includes a rack 310 and a pinion 320; the rack 310 is fixed on the fixing frame 100, the gear 320 is engaged with the rack 310, and the gear 320 is sleeved on the rotating shaft 200.

In other embodiments, the transmission assembly 300 may have other structures that can realize both the rotation of the rotating shaft 200 and the movement of the rotating shaft 200. In addition, in the process of the meshing transmission between the gear 320 and the rack 310, the conversion between circular motion and linear motion can be realized, so that the rotating member 400 can perform linear motion.

In a particular embodiment, mount 100 includes guide plate 120, support post 130, and mount 140; the guide plate 120 is arranged parallel to the mounting base 140; the supporting column 130 is located between the guide plate 120 and the mounting seat 140, and a mounting chamber is formed among the guide plate 120, the supporting column 130 and the mounting seat 140; the transmission assembly 300 is disposed within the mounting chamber.

Specifically, the guide plate 120 is provided with an adjustment groove 110 along the width direction of the rotation member 400 for guiding the rotation shaft 200 such that the rotation shaft 200 moves along the width direction of the rotation member 400. During the rotation of the rotation member 400, the rotation shaft 200 rotates, and the other end of the rotation shaft 200 moves relative to the rack 310 during the transmission, i.e., the rotation shaft 200 moves on the fixing frame 100, wherein the adjustment groove 110 guides the rotation shaft 200 to adjust the distance of the rotation shaft 200 relative to the side edge of the rotation member 400.

In the embodiment, the guide plate 120 is provided with scale marks 121 for measuring the moving distance of the rotating shaft 200; the scale lines 121 are disposed along the length direction of the adjustment groove 110.

On one hand, the slider 600 is used to prevent the loss of the rotation shaft 200, and on the other hand, the matching degree of the slider 600 and the adjustment groove 110 is relatively higher, so that the opening and closing of the rotation member 400 are more stable.

In a particular embodiment, the switch mechanism further comprises a connector 700; the connection member 700 is disposed at the top and/or bottom of the fixing member 500, one end of the connection member 700 is connected to the fixing member 500, and the other end of the connection member 700 is rotatably connected to the rotation shaft 200.

Specifically, the connection member 700 is used to connect the rotation shaft 200 with the fixing member 500, and the connection member 700 facilitates the manufacture and installation of the switching mechanism.

Specifically, the illumination unit 800 is used to illuminate the inside of the fixing member 500. When the rotating member 400 is opened, the rotating shaft 200 drives the rotating switch 900 to rotate, the internal circuit of the rotating switch 900 is closed, and the lighting unit 800 is in a power-on state. When the rotating member 400 is turned off, the rotating shaft 200 drives the rotating switch 900 to rotate, the internal circuit of the rotating switch 900 is turned off, and the lighting unit 800 is in a power-off state.

The rotary switch 900 is provided on the rotary shaft 200 to rotate coaxially with the rotary shaft 200. When the rotating member 400 is turned on, the rotating shaft 200 drives the rotating switch 900 to rotate, the internal circuit of the rotating switch 900 is turned off, and the power consumption unit stops working. When the rotating member 400 is closed, the rotating shaft 200 drives the rotating switch 900 to rotate, the internal circuit of the rotating switch 900 is closed, and at this time, the power utilization unit operates.

In another embodiment, when the rotation member 400 is opened, the rotation shaft 200 drives the rotation switch 900 to rotate, and the internal circuit of the rotation switch 900 is closed, and the power utilization unit is operated.

When the distance between the side wall of the box body structure and other objects is too small, the opening degree of the door body is easily limited, and then the opening degree of the door body is smaller. The opening and closing mechanism adjusts the opening degree of the door body by changing the relative distance between the rotating shaft 200 and the rotating member 400.
