Description of the drawings
Fig. 1 is the structural representation of the closing locking device according to vacuum contactor of the present utility model.
Main Reference Numerals explanation：
1- cranes, 2- leading screws, 3- slide closures, 4- well head formula pull bar connecting rods, 5- well head formula pull bar rotating shafts, 6- connects
Piece, 7- packing rings.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by specific embodiment.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As shown in figure 1, the locking shelf of vacuum contactor includes the crane 1 installed on the end of leading screw 2, slide closure 3 sets
Put in the lower section of crane 1, and slide closure 3 can horizontally slip in the lower section of crane 1.
As shown in figure 1, including well according to the closing locking device of the vacuum contactor of the utility model specific embodiment
