The present invention is a kind of safety isolated switch, including base plate, it is provided with guide post in the both sides of base plate, the guide post of side is provided with elastic telescoping bar, one end of elastic telescoping bar is flexibly connected with guide post by rotating shaft, the other end of elastic telescoping bar is flexibly connected with tool arm by rotating shaft, and the other end of tool arm is flexibly connected with the guide post of opposite side by rotating shaft；That prolongs guide post is axially arranged with guide groove, between two guide grooves, card has push pedal, push pedal is provided with chute, what tool arm was movable with the connection axle of the link of elastic telescoping bar is stuck in chute, it is fixed with workbench between two guide posts, being provided with swing arm in the outside of push pedal, swing arm is flexibly connected with push pedal through the screw in the middle of workbench again through rotary flange dish, and the outer surface at swing arm is provided with the external screw thread that the female thread with screw matches.
Further, described elastic telescoping bar includes fixed pole and lever, is provided with the first baffle plate in the inside of fixed pole, the lower end of fixed pole is provided with second baffle, the upper end of lever extend into the inside of fixed pole, is fixed with snap ring on the lateral wall of lever, is provided with spring between snap ring and the first baffle plate.
Further, it is provided with block at chute near one end of tool arm.
Further, described spring is constant force spring.
Further, lubricating oil is all scribbled in described guide groove and chute.
The invention has the beneficial effects as follows: by rotate swing arm, it is possible to easily laborsaving and accurately by tool arm promote put in place, do not have the situation of unexpected power-off or energising, the safety of production be greatly improved.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of safety isolated switch of the present invention；
Fig. 2 is the sectional view of the present invention；
Fig. 3 is the structural representation of elastic force telescopic rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
A kind of safety isolated switch as shown in Figure 1-Figure 3, including base plate 1, it is provided with guide post 2 in the both sides of base plate 1, the guide post 2 of side is provided with elastic telescoping bar 3, one end of elastic telescoping bar 3 is flexibly connected with guide post 2 by rotating shaft, the other end of elastic telescoping bar 3 is flexibly connected with tool arm 4 by rotating shaft, and the other end of tool arm 4 is flexibly connected with the guide post 2 of opposite side by rotating shaft；That prolongs guide post 2 is axially arranged with guide groove 5, between two guide grooves 5, card has push pedal 6, push pedal is provided with chute 7, what tool arm 4 was movable with the connection axle of the link of elastic telescoping bar 3 is stuck in chute 7, workbench 10 it is fixed with between two guide posts 2, be provided with swing arm 8 in the outside of push pedal 6, swing arm 8 is flexibly connected with push pedal 6 through the screw in the middle of workbench 10 again through rotary flange dish 11, and the outer surface at swing arm 8 is provided with the external screw thread that the female thread with screw matches
