the second spring 201c tends to push the switching plate 202 upward so that the wide-side end 202a comes into contact with the cam 203 b.
The protective door 200 is also provided with a push-pull handle 204; the switch knob 203a is disposed higher than the push-pull knob 204.
In this embodiment, the push-pull handle 204 is used to control the movement of the protective door 200, and is set at a height that is convenient for grasping the closing force, and the switch handle 203a is set at a higher height to avoid the door being opened by mistake.
It should be noted that both the inside and outside of the protection door 200 are provided with the push-pull handle 204 and the opening and closing handle 203 a.
When the protective door is used, the push-pull handle 204 is dragged to enable the protective door 200 to completely shield the access area B1, and the plug column 301 enters the lock hole 101; when the switch handle 203a is turned, referring to fig. 9 initially, the wide-side end 202a contacts the cam 203b on the side close to the axial center, and the switch handle 203a is turned, the cam 203b rotates, the contact point between the wide-side end 202a and the cam 203b becomes farther from the axial center, that is, the switch plate 202 is pushed downward, and the second spring 201c is compressed.
The nut plug 303 is fixed to the end of the circular hole 301a by a screw connection, the first spring 303b pushes the pin shaft 302a to the depth of the circular hole 301a, that is, the inclined surface 302a-5 is always in contact with one side of the conversion plate 202 under the action of the first spring 303b, so that during the downward movement of the conversion plate 202, the inclined surface 302a-5 initially contacts with the short side end 202b, then contacts with the inclined surface connection end 202c, and then contacts with the wide side end 202a, and during this process, the inclined surface 302a-5 and the pin shaft 302a are both integrally moved in the left direction as shown in fig. 9.
When the pin shaft 302a moves, the lifting plate 302a-3 moves along with the pin shaft, and because the middle part of the buckle 302b is connected with the shaft arranged in the outer notch 301c, and the lifting plate 302a-3 moves towards the left side direction in fig. 9, the lifting plate 302a-3 pushes the inner contact end 302b-2, so that the buckle 302b rotates, the outer buckle end 302b-1 extends outwards, and the outer buckle end 302b-1 is buckled at the side wall of the clamping groove 102 to keep connection and locking. At this time, the wide side end 202a contacts the cam 203b farthest from the axial center and keeps balance, and it should be noted that the cam 203b does not rotate by itself without an external force because a large external force is not applied to the cam 203b when it rotates.
Other external structures may be provided to maintain the cam 203b in this configuration.
