Wherein, described block comprises vertical plane and inclined plane, and the angle between described vertical plane and described inclined plane is obtuse angle.
Wherein, described push rod is fixed on described vertical plane.
Wherein, the area of described vertical plane is greater than the area on described inclined plane.
Wherein, described lock housing is provided with the fixing hole for being fixed in power distribution panels.
Wherein, described lock housing is provided with the push-rod hole passed for described push rod, and described push rod can slide along described push-rod hole.
Wherein, described push rod is screwed in described block.
The beneficial effects of the utility model:
Mechanical interlock of the present utility model, by can be provided with the block that can slide relative to it in lock housing, and block is fixed with push rod, and then drive block motion to support dwelling in the cross bar of off-state by promoting push rod, when left side panel switches need be disconnected, the cross bar in downward pressing left side makes left side panel switches be in off-state, then push rod is promoted left, and then drive block to left movement with the cross bar making block support left side panel switches, now, right side panel switches are in on-state, accordingly, adopt same principle can realize the disconnection of right side panel switches, the connection of left side panel switches, not only operating process is easy for this switch machine interlock, and building block is few, structure is simple, production cost is low.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
The specific embodiment of a kind of mechanical interlock for switch of the present utility model, as depicted in figs. 1 and 2, this switch machine interlock is arranged between two panel switches 1, two panel switches 1 are all installed on power distribution panels 6, each panel switches 1 are equipped with the cross bar 11 for on/off, when cross bar 11 is in reset position, panel switches 1 are in on-state, and pressing cross bar 11 makes panel switches 1 be in off-state downwards.
Mechanical interlock of the present utility model, its structure comprises lock housing 2, block 3 and push rod 4, lock housing 2 is provided with the fixing hole 21 for being fixed in power distribution panels 6, block 3 to be arranged in lock housing 2 and can to slide relative to lock housing 2, block is fixed in one end of push rod 4, the other end of push rod 4 stretches out in lock housing 2, by promoting push rod 4, and then drives block motion to make block support dwelling in the cross bar 11 of off-state.
As shown in Figure 3, when left side panel switches 1 need be disconnected, the cross bar 11 of downward pressing left side panel switches 1 makes left side panel switches 1 be in off-state, then push rod 4 is promoted left, and then drive block to support dwelling in the left side cross bar 11 of off-state to left movement to make the left part of block, now, the right part of block bounces back in lock housing 2, and the cross bar 11 of right side panel switches 1 resets and makes right side panel switches 1 be in on-state.Accordingly, as shown in Figure 4, when right side panel switches 1 need be disconnected, the cross bar 11 of downward pressing right side panel switches 1 makes right side panel switches 1 be in off-state, then promote push rod 4 to the right, and then drive block to move right to make the right part of block to support dwelling in the right side cross bar 11 of off-state, now, the left part of block bounces back in lock housing 2, and the cross bar 11 of left side panel switches 1 resets and makes left side panel switches 1 be in on-state.
Switch machine interlock of the present utility model is not only easy and simple to handle, and building block is few, and structure is simple, and then production cost is low.
In the present embodiment, block comprises vertical plane 31 and inclined plane 32, angle between vertical plane 31 and inclined plane 32 is obtuse angle, increase the structural strength of block, and the gradient on inclined plane 32 is identical with the gradient of the bearing surface of the cross bar 11 when being in off-state, to reach stability and the reliability that block supports cross bar 11, in addition, the area of vertical plane 31 is greater than the area on inclined plane 32, the overall construction intensity of further reinforcement block, and push rod 4 is fixed on vertical plane 31, inclined plane 32 is made not to be vulnerable to large External Force Acting and to be out of shape, and then impact interlocking performance.
Concrete, push rod 4 is vertically fixed on the vertical plane 31 of block by screw 5, and fixation is reliable.
Concrete, lock housing 2 is provided with the push-rod hole 22 passed for push rod 4, and push rod 4 can slide along push-rod hole 22, and then push rod 4 drives block relative to lock housing 2 reciprocating motion.
Above embodiment is only in order to illustrate the technical solution of the utility model, but not the restriction to the utility model protection range, can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
