Embodiment:
The application by the restriction of following embodiment, can not determine concrete execution mode according to the technical scheme of the application and actual conditions.
Embodiment: as shown in Figure 1, the earthing clamp device with automatic blocking function comprises the U-shaped wire clamp head 1 with opening, described wire clamp head 1 side is connected with wire clamp bar 3, online clamping bar 3 lower end is provided with cavity bar cover 15, symmetrical arc thread tension stud 2 is provided with in online chuck 1, being lived by the first rotating shaft 5 and are connected in described thread tension stud 2 lower end and wire clamp head 1 both sides, is connected with the first torsion spring 4 between the first rotating shaft 5 and thread tension stud 2 lower end.Bar cover 15 cavity in be equiped with locking device 6, described locking device 6 comprises the deadlock lever 8 in order to blockade line chuck 1 opening, and with the second rotating shaft 10 that deadlock lever 8 links, the second rotating shaft 10 is socketed with rotating disk 9.Overlap on 15 cavity madial walls at bar and offer symmetrical perforate 16, baffle plate 14 is provided with on the downside of two perforates 16, inside two perforates 16, opening part is provided with ball 12, return spring 13 is connected between two ball 12 lower ends and two baffle plates 14, living with the lower end of two connecting rods 11 respectively and be connected in two ball 12 upper ends, lives with rotating disk 9 and be connected in the upper end of two connecting rods 11.
Second rotating shaft 10 is equiped with the second torsion spring for resetting.
Described two connecting rod 11 upper ends are with near rotating disk 9 excircle place, work is connected, and work is connected to same position place.
Described two baffle plates 14 tilt, symmetry is laid in the cavity of bar cover 15, and the upper end of described two baffle plates 14 slopes inwardly, and form the space carrying ball 12 between the cavity inner wall that two baffle plates 14 and bar overlap 15.The upper end of two baffle plates 14 and cavity bar overlap spacing between 15 inwalls and are not less than ball 12 radius.Such setting can prevent ball 12 from dropping out, thus guarantees that automatic blocking function is normal.
Described perforate 16 is large, the outer young through hole of internal orifice, and ball 12 diameter is less than perforate 16 inner port diameter, is greater than perforate 16 external port diameter.
Described bar overlaps 15 internal cavity lower ends and has an opening, and insulating bar 7 is inserted by this opening.This opening diameter is less than cavity diameter, thus forms a terrace with edge structure, and this terrace with edge structure width is not more than ball 12 radius, thus makes ball 12 when overlapping between 15 at baffle plate 14 and bar, and the floor projection of ball 12 is positioned at aforementioned opening.
During use, wire clamp head 1 is socketed in insulating bar 7 upper end by bar cover 15, and insulating bar 7 upper end, after the cavity entering bar cover 15, promotes ball 12 upwards, until ball 12 enters in perforate 16, in the motion process of ball 12, drivening rod 11 moves upward, thus promotion rotating disk 9 rotates counterclockwise, and then drive deadlock lever 8, deadlock lever 8 front end is separated with clamp head 1, forms opening, now wire can be inserted in clamp head 1 by opening part.Withdraw insulating bar 7 subsequently, ball 12 is withdrawn with insulating bar 7, under the effect of return spring 13, depart from perforate 16 gradually, thus drive rotating disk 9 to rotate clockwise by connecting rod 11, simultaneously under the effect of the second torsion spring, deadlock lever 8 front end is close with clamp head 1 gradually, until closed, complete closed.Ball 12 falls between baffle plate 14 and bar cover 15 again.
Above technical characteristic constitutes the most preferred embodiment of the application, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
