As a kind of improvement of the utility model, described slide guiding body and limit body are provided with circular hole, and described slide guiding body links to each other through bearing pin with limit body.
Another kind as the utility model improves, and described resetting device is a back-moving spring.
Another kind as the utility model improves, and described lock tube is provided with groove, and the cross section of described groove and rotating shaft and groove fit end is the hexagon shape.
Another kind as the utility model improves, and has bar hole on the described lock tube, and screw passes bar hole and the rotating shaft Joint on the lock tube.
Another kind as the utility model improves, and described slide guiding body and limit body are cylinder, and the side of said projection and the side of limit body fit.
Another kind as the utility model improves, and described Z letter stencil is located on the supporting bracket of bearing.
The beneficial effect of the utility model is; The limit body of having set up projection and having matched with projection; When open at the back door, this moment resetting device make limit body by second place slippage to primary importance, play position-limiting action; Guarantee that earthed switch can't connect, guaranteed the life security the when staff operates like this.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Structural representation when accompanying drawing 2 is in primary importance for limit body 42 in the accompanying drawing 1.
Structural representation when accompanying drawing 3 is in the second place for limit body 42 in the accompanying drawing 1.
Among the figure, bearing 1, supporting bracket 11, lock tube 2, projection 21, groove 22, bar-shaped trough 23, rotating shaft 3, Z letter stencil 4, slide guiding body 41, limit body 42, back-moving spring 43, bearing pin 44, screw 5.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 combine Fig. 2, shown in 3, a kind of earthed switch operating mechanism interlock comprises bearing 1; Described bearing 1 is provided with locking device, and described locking device comprises lock tube 2 and rotating shaft 3, and described rotating shaft 3 one ends pass and prop up; Supporting bracket 11 on 1 be sheathed in the lock tube 2 and with its transfer torque radially; Described bearing 1 is provided with Z letter stencil 4, and described Z letter stencil 4 is provided with slide guiding body 41 and limit body 42, is respectively equipped with on the described bearing 1 and slide guiding body 41 and limit body 42 corresponding through holes; Described slide guiding body 41 is connected with limit body 42; Described slide guiding body 41 is provided with resetting device, and described limit body 42 has the primary importance and the interior second place of retraction through hole of passing 1 position-limiting action of bearing, and described lock tube 2 is provided with the projection 21 that matches with limit body 42 primary importances.The beneficial effect of the utility model is; The limit body of having set up projection and having matched with projection; When open at the back door, this moment resetting device make limit body by second place slippage to primary importance, play position-limiting action; Guarantee that earthed switch can't connect, guaranteed the life security the when staff operates like this; And during closing back door, slide guiding body is stressed, make limit body by the primary importance slippage to the second place, and compression resetting device, can normally connect earthed switch this moment.
