Abstract
The utility model provides an insulating operating rod which comprises a T-shaped head and an insulating rod, wherein a vertical part of the T-shaped head is provided with a stop lever through a rotating shaft, a limiting rod is arranged on the vertical part of the T-shaped head above the stop lever through the rotating shaft, a spring is arranged between the limiting rod and the vertical part of the T-shaped head, the lower end of the limiting rod takes the shape of a wedge, a notch is arranged in the middle of the upper side of the stop lever, and the limiting rod is provided with an operating rope. In the utility model, the T-shaped head of the insulating operating rod is provided with the stop lever and the limiting rod, and the wedge-shaped lower end of the limiting rod is matched with the notch of the stop lever, so as to prevent the stop lever from rotating and a moving contact from dropping.
Description
Technical field
The utility model relates to mechanical field, and particularly urban distribution network circuit disconnecting link getting instrument specifically is a kind of insulating bar.
Background technology
Insulating bar is to be the main tool of getting disconnecting link in the urban distribution network circuit, and it has characteristics easy to use, that cost is low, safe and reliable.Be that horizontal component by insulating bar front end T shape head separates moving contact with fixed contact when getting the disconnecting link moving contact, penetrate buckling on the moving contact with the vertical part of T shape head again moving contact is taken off from fixed contact.And with moving contact be suspended on the fixed contact sequence of movement in contrast.In use, by longer to insulating bar, and the vertical portion of its front end T shape head generally has only tens centimetres, therefore, moving contact is taken off to tend to the process moving contact fallen down from quiet head break, and causes power circuit maintenance cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of insulating bar, and described this insulating bar will solve in the prior art at the getting moving contact and tend to technical problem that moving contact is dropped and causes moving contact to damage from the T shape head of insulating bar.
The purpose of this utility model is achieved through the following technical solutions: comprise T shape head and insulating bar, on the vertical part of T shape head, be provided with pin by rotating shaft, above pin, be provided with gag lever post by rotating shaft with the vertical part of T shape head, be provided with spring between this gag lever post and the T shape head erect part, the gag lever post lower end is wedge shape, middle side part is provided with breach on pin, is provided with the operation rope on gag lever post.
Spring between gag lever post and the T shape head erect part is to be installed on gag lever post upper end rotating shaft torsion spring, and this torsion spring applies counterclockwise torque to gag lever post.
Spring between gag lever post and the T shape head erect part is to be horizontally disposed compression spring, and this spring is located at the rotating shaft below of gag lever post.
Gag lever post length is 10 centimetres, and the distance between the rotating shaft of gag lever post and the rotating shaft of pin is 5 centimetres, and the distance between the breach of blocking and its rotating shaft is 7 to 8.5 centimetres.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with pin and gag lever post on the T of insulating bar shape head, pin can freely rotate around its rotating shaft, the physical slot of pin is slightly oblique to a T shape horizontal component one square neck, gag lever post is in oblique extended state naturally under spring action, when the vertical part that needs T shape head is arranged in buckling of moving contact, by operation rope pulling gag lever post, make it be vertical attitude, and this moment pin be oblique downwards, be convenient to buckle by, when moving contact is taken off in the process, gag lever post is unclamped, spacing being outside oblique the stretching, and moving contact buckles and be between a pin and the T shape horizontal component is when if moving contact has drop dangerous, buckle to make on the pin and rotate, at this moment the tapered end of gag lever post lower end matches with the breach of pin, stops pin to rotate, and prevents that moving contact from dropping.If rotating shaft place of gag lever post is provided with torsion spring, total is compacter.
Description of drawings
Fig. 1 is the structural representation of insulating bar of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model insulating bar, comprise T shape 2 and insulating bar 1, on the vertical part 21 of T shape 2, be provided with pin 3 by rotating shaft, pin 3 is positioned at the top of a T shape horizontal component, the nature of pin is slightly stretched out to the horizontal component direction of T shape 2 for its lower end, above pin 3, be provided with gag lever post 4 with the vertical part of T shape 2 by rotating shaft, be provided with spring 5 between this gag lever post 4 and the T shape head erect part 21, gag lever post 4 lower ends are wedge shape, and middle side part is provided with breach 31 on pin 3, when pin goes near level, the tapered end of gag lever post 4 lower ends matches with breach 31 on the pin, is provided with operation rope 6 on gag lever post 4.Spring 5 between gag lever post and the T shape head erect part is to be horizontally disposed compression spring, and this spring is located at the rotating shaft below of gag lever post, and the nature that makes gag lever post like this is oblique stretching out.Gag lever post 4 length are 10 centimetres, and the distance between the rotating shaft of gag lever post 4 and the rotating shaft of pin is 5 centimetres, and the distance between the breach on the pin and its rotating shaft is 8 centimetres.
Certainly, the spring between gag lever post and the T shape head erect part also can be to be installed on gag lever post upper end rotating shaft torsion spring, and this torsion spring applies counterclockwise torque to gag lever post.Distance between breach on the pin and its rotating shaft be 7 to 8.5 centimetres all passable, as long as make pin be level or slightly downward-sloping all passable when breach on the pin cooperates when gag lever post.
