Utility model content
The purpose of this utility model is the weak point existed for prior art, provides one locking for bus plugging box
The plugging box interlocking mechanism that precision height, highly versatile, reliability are high, easy to operate.
In order to achieve the above object, the utility model proposes a kind of plugging box interlocking mechanism, including being arranged on jack box side
Left jam plate on banding plate, right jam plate, bolt, locking nut and axle sleeve；Described left jam plate and right jam plate are provided with arc limit
Hole and position rotating hole, position, is provided with the grapple for the bus duct that is connected, described left jam plate and the right side at left jam plate with right jam plate bottom
The position rotating hole of jam plate is connected with the installation of jack box side shrouding by axle sleeve and locking nut, sets in described arc-shaped limit hole
There is the bolt being connected with jack box side shrouding.
Jack box, when installing with bus, opens grafting case lid door, inwardly pulls left jam plate, right jam plate；Due to left jam plate,
Right jam plate bottom is provided with position rotating hole, is fixed on jack box side shrouding by bolt and lock nut, the most inwardly pulls
With the position rotating hole of bottom as the center of circle when dynamic left jam plate, right jam plate, the arc-shaped limit hole on top is radial inward motion；Install
First pull during bus so that left and right grapple separately；Then bus duct edge protuberance is partially placed into left jam plate and right jam plate
Between；Finally it is rotated further by pulling and makes left jam plate and right jam plate close up to block the part of bus duct edge protuberance and realize consolidating of bus duct
Dingan County fills；Remove the step of bus duct in contrast.
This utility model limits scheme further: aforesaid plugging box interlocking mechanism, described left jam plate and right jam plate upper
Minister's degree exceeds jack box height, is provided with two for limiting left jam plate and the lock of right jam plate position on the cover plate of jack box top
Determining square hole, described locking square hole is arranged on left jam plate and right jam plate is on locking state position.In order to improve this connection further
The reliability of latch mechanism, when jack box door-plate cuts out, owing to left jam plate and right jam plate upper end are higher than the top of jack box, it is necessary to
Locked and put in place, jack box door-plate could be closed；The cover plate of jack box is provided with two locking square holes, when grafting chamber door is closed
Time, within left jam plate and right jam plate are positioned at locking square hole, prevent from loosening.
Aforesaid plugging box interlocking mechanism, the hook of described left jam plate and right jam plate bottom is in sustained height.
Further, aforesaid plugging box interlocking mechanism, described arc-shaped limit hole is arranged on the upper of described position rotating hole
Side.
Beneficial effect: of the present utility model simple to operation, only needs left jam plate and right jam plate separately or to be closed up simultaneously
, it becomes possible to realize jack box interlocking on bus duct, owing to using cover plate to limit left jam plate and the activity of right jam plate, keep away
Exempt from dangerous generation, have higher security reliability, effectively prevent jack box maloperation in the course of the work from maybe should install not
Put in place and cause danger；This structure highly versatile, left jam plate and the independent operation of right jam plate distribution, non-interference, simple in construction, use
During be difficult to break down, reliability is high, and cost of manufacture is low；Only need to pull left jam plate and right jam plate during use, make left and right grab
Hook together and be stuck in the part that bus duct is protruding, it is possible to lock accurately and lock precision height.

Detailed description of the invention
Embodiment
The present embodiment provides a kind of plugging box interlocking mechanism, structure as shown in Figures 1 to 5, including left jam plate 1, right jam plate
2, bolt 3, locking nut 4, axle sleeve 5, locking square hole 6；Left jam plate 1 and right jam plate 2 are separately fixed on jack box by bolt 3
On shrouding 7, locking nut is the nut that non-metallic material is made, and the position that left jam plate 1 and right jam plate 2 are installed screw 3 is provided with
The arc-shaped limit hole of horizontal direction；The bottom, arc-shaped limit hole of left jam plate 1 and right jam plate 2 is equipped with position rotating hole；Left jam plate 1
It is in sustained height when being arranged on jack box side shrouding with right jam plate 2；Jack box, when installing with bus, opens jack box top
Portion's cover plate, inwardly pulls left jam plate 1 and right jam plate 2；Owing to left jam plate 1, right jam plate 2 bottom are provided with position rotating hole, pass through spiral shell
Bolt 3 and locking nut are fixed on jack box side shrouding, with the location of bottom when the most inwardly pulling left jam plate 1, right jam plate 2
Rotating hole is the center of circle, and the arc-shaped limit hole on top is radial inward motion；First left jam plate 1 and right jam plate is pulled when bus is installed
2 make left and right grapple separate to both sides；Then being partially placed into bus duct edge protuberance between left jam plate 1 and right jam plate 2；
Finally it is rotated further by pulling left jam plate 1 and right jam plate 2 makes left and right grapple close up to block the part of bus duct edge protuberance and realize bus
The fixed installation of groove；Remove the step of bus duct in contrast.In order to improve the reliability of this interlocking mechanism further, work as grafting
When box top cover plate is closed, owing to left jam plate 1 and right jam plate 2 upper end are higher than the top of jack box, the cover plate of jack box is provided with two
