Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the part-structure figure of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, rail traffic junction box, including cabinet 1, rotate the cover 2, arc fixed board 3, limit bolt 4,
Arc movable plate 5, sealing structure 6 and fastening bolt 7.The side of cabinet 1 offers an operating groove.The edge of operating groove is arranged
There is seal convexity.N threaded hole, 5≤n≤15 are provided on seal convexity.Rotate the cover 2 one side edge and the side of cabinet
It is hinged by articulated shaft.It rotates the cover and is fixed with seal washer on 2 medial surface.Seal convexity edge on seal washer and cabinet
Articulated shaft axis it is circumferentially aligned.It rotates the cover and is provided with n through-hole on 2.Fastening bolt 7 is provided in n through-hole.Rotation
N through-hole on cover board 2 is with n threaded hole on seal convexity respectively along the circumferentially aligned of articulated shaft axis.Seal washer energy
Enough meet the protection level requirements of cabinet IP65.
The inner end of arc movable plate 5 is fixed with rotating the cover 2.The inner end of arc fixed board 3 and the inside of cabinet 1 are fixed.Arc
The outer end of movable plate 5 offers lock-bit hole.Arc groove is offered on arc fixed board 3.The radius of arc groove inside edge is r, center
Axis and articulated shaft axis collinear, 8mm≤r≤20mm.The groove width of arc groove is a, 3mm≤a≤8mm.The axis of limit bolt
With at a distance from articulated shaft axis be equal to r+0.5a.The bottom end of limit bolt 4 is provided with screw thread, and passes through lock-bit hole and arc groove.
Detent block is arranged in the top of limit bolt 4.The bottom end of limit bolt 4 is threadedly coupled with stop nut.By tightening limit bolt 4
With stop nut, enable to rotate the cover 2 fixations at an arbitrary position, convenient for the operation of staff.
The working principle of the utility model is as follows:
When needing wiring, staff backs out so fastening bolt, and opens and rotate the cover 2, tightens lock-bit bolt later
With lock-bit nut so that rotating the cover fixation.
After staff completes wiring, lock-bit bolt and lock-bit nut are unclamped, and overturning covers after rotating the cover 2, it will
All fastening bolts n tapped through hole of precession and are tightened respectively.
