Description
Technical field
The present invention relates to bridge field, specifically a kind of novel bridge facility.
Background technology
In the infrastructure of bridge, the more seat that is electrically connected can be all preset, these seats that are electrically connected are mainly electrified for the later stage
Maintained equipment grafting power supply use, but these are electrically connected, a Setting pattern is excessively simple, with during electrified maintained equipment grafting only
Only it is the state remained stationary as by the frictional force being electrically connected between head and the seat that is electrically connected, this power supply state is extremely unstable, under not
The heart, which is kicked, to be encountered when being electrically connected head or tripping supply lines, it is easy to which the head that causes to be electrically connected comes off and electrified maintained equipment is surprisingly broken
Electricity;Further, since the seat that is electrically connected is directly to be electrically connected with city, and the conducting strip in it sets relatively outer, this conducting strip
It is easy to be touched by sheet metal or metal rod, therefore, when the people for lacking awareness of safety inserts sheet metal or metal rod
Enter to accident when being electrically connected in seat, easily got an electric shock, cause casualties, larger potential safety hazard be present.
The content of the invention
For the deficiency of above-mentioned technology, the present invention proposes a kind of novel bridge facility.
A kind of novel bridge facility of the present invention, including be electrically connected seat and the head that is electrically connected that is connected with electrified maintained equipment,
A left side that is electrically connected is correspondingly provided with fixed block up and down, and screw is provided with the fixed block, described to be electrically connected in a right side
Cavity is provided with, the cavity left end wall is correspondingly provided with plug together groove of the beginning towards the cavity up and down, described to plug together groove
The pin that conducts electricity is installed in end wall, it is described plug together groove and become estranged in the end wall of the pin that conducts electricity to be provided with push to slide groove, it is described push to slide groove with
The groove junction that plugs together is fixedly installed separation plate, is provided with the separation plate described in UNICOM and pushes to slide groove and described plug together groove
Logical conjunction groove, described push to slide be provided with inserting-plate hole in groove left end wall, described push to slide is movably installed with slide unit in groove, in the slide unit
The beginning is provided with towards the logical oblique arrival slot for closing groove, the slide unit left side is installed with what is be engaged with the inserting-plate hole
Inserted sheet, the cavity is correspondingly provided with end wall up and down turns chamber, described to turn chamber right-hand member wall and be provided with to penetrate hole, the seat right side that is electrically connected
Side end face is additionally provided with holding protective cover device, and the holding protective cover device includes end cap and hand-held pole;A left side that is electrically connected is corresponding up and down
Be provided with and plug together the bar that plugs together that groove is engaged with described, it is described plug together to be provided with bar left end end face outside install groove, the peace
If groove right-hand member wall is provided with slope, described install in groove is rotatably mounted with flap at the slope bottom, institute
State flap end tail and be rotatably mounted with spin, an end face outside that is electrically connected is provided with arc groove, can turned in the arc groove
Rotating cylinder is installed dynamicly, the rotating cylinder left end is provided with is provided with behaviour with the lock shaft for turning chamber and being engaged, the rotating cylinder right-hand member
Control ring.
Valuably or exemplarily, wherein, the flap, which is become estranged in the end face of slope, is provided with deep gouge, in the deep gouge
It is installed with and first spring installed groove inwall and be connected.
Further technical scheme, the groove that plugs together in the end wall for pushing to slide groove homonymy with being provided with delivery groove.
Further technical scheme, the slide unit right side is installed with pushes to slide what groove right-hand member wall was fixedly connected with described
Second spring.
Further technical scheme, the inserted sheet are electrically connected with the pin that conducts electricity.
Further technical scheme, the cavity radius are same with the radius of the head that is electrically connected.
Further technical scheme, the oblique arrival slot right-hand member, which is provided with, tiltedly supports face.
Further technical scheme, it is described plug together bar left end and be provided with lead slotting face.
Further technical scheme, the end cap are arranged at a right side wall that is electrically connected by what movable axis can rotate upwardly and downwardly
Above the cavity, the hand-held pole is fixed with below the end cap lateral surface.
The beneficial effects of the invention are as follows:
Due to being electrically connected seat in original state in apparatus of the present invention, the slide unit is in the presence of second spring by the right
Pull and the inserted sheet is departed from the inserting-plate hole, therefore, the pin that conducts electricity is not charged, when lacking the people of awareness of safety by metal
