Abstract
The invention discloses a grounding wire grounding connection device which comprises a base. One end of the base is provided with a busbar which is provided with a wire pressing hole, and the other end of the base is provided with an electric contact face and a supporting wall. The supporting wall is hinged to one end of a pressing rod through a rotating shaft, and the middle of the pressing rod is vertically connected with a movable shaft. Through holes which are perpendicular to the axial direction of the movable shaft are formed in the two ends of the movable shaft, and the through holes are connected with U-shaped hooks. Two legs of the U-shaped hooks penetrate through the through holes and then are sleeved with springs, and spring limiting devices are arranged at the tail ends of the two legs of the U-shaped hooks. When the grounding wire grounding connection device is used, a grounding pile is placed between the U-shaped hooks and the electric contact face, the pressing rod is rotated so that the U-shaped hooks and the electric contact face can tightly clamp the grounding pile, after the pressing rod passes through a dead point of a connecting rod mechanism, self-locking of the connection device is formed, and the grounding connection operation of a grounding wire is achieved.

As preferred version of the present invention, described electric interface is provided with lead.
As preferred version of the present invention, described U-shaped hook is provided with locating convex block.
As preferred version of the present invention, described spring stopper is adjustable nut.
As preferred version of the present invention, described depression bar and pedestal are provided with corresponding lockhole.
As preferred version of the present invention, the vertical height being vertically highly less than rotating shaft of lockhole on described pedestal.
When ground connection device for ground wire of the present invention uses, allow ground stud between U-shaped hook and electric interface, by rotating depression bar, make U-shaped hook and the stake of electric interface clamping ground, when depression bar is behind linkage dead point, jockey forms self-locking, namely completes the grounding connection operation of earth connection.In ground connection device for ground wire of the present invention, spring ensure that the reliability of connection effectively, the requirement of dynamic and thermal stability when making junction have enough contacts to meet short circuit.Ground connection device for ground wire of the present invention, easy to operate, installing/dismounting is quick, and safe and reliable, structure is simple.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Fig. 1 is the structural representation of ground connection device for ground wire of the present invention.
Mark in figure: 1 is pedestal, and 2 is bus-bar, and 3 is line ball hole, 4 supporting walls, and 5 is electric interface, 6 is rotating shaft, and 7 is depression bar, and 8 is movable axis, and 9 is through hole, and 10 is U-shaped hook, 11 is spring, and 12 is spring stopper, and 13 is lead, and 14 is lockhole, and 15 is locating convex block.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Ground connection device for ground wire of the present invention as shown in Figure 1, comprise pedestal 1, described pedestal 1 one end is provided with bus-bar 2, bus-bar 2 offers line ball hole 3, the other end of described pedestal 1 is provided with electric interface 5 and supporting walls 4, described supporting walls 4 is hinged by rotating shaft 6 and depression bar 7 one end, movable axis 8 is vertically connected with in the middle part of described depression bar 7, described movable axis 8 two ends are provided with the through hole 9 axially vertical with it, described through hole 9 is connected with U-shaped hook 10, the bipod of described U-shaped hook 10 has spring 11 through encapsulation after described through hole 9, the end of described U-shaped hook 10 bipod is provided with spring stopper 12.
As shown in Figure 1 in ground connection device for ground wire of the present invention, electric interface 5 is provided with lead 13, U-shaped hook 10 is provided with locating convex block, this structure, U-shaped hook 10 is pulled at depression bar 7, make electric interface 5 in the process of Earth pile-head movement, ensure that electric interface lateral displacement does not occur, prevent from connecting the relative sliding between rear device and Earth pile-head.Spring stopper 12 is designed to adjusting nut, makes the deflection of spring 11 adjustable, thus can obtain more suitably contact.For preventing the unexpected tripping of depression bar 7, depression bar 7 and pedestal 1 are designed with corresponding lockhole 14, when depression bar 7 turns to two lockholes coincidences, use five is anti-lock passes two lockholes and locks.For allowing device can reliably self-locking, on pedestal lockhole 14 to be vertically highly designed to than rotating shaft 6 vertically highly low.
When ground connection device for ground wire of the present invention uses as shown in Figure 1, bus-bar 2 connects earth connection by line ball hole 3.Rotate depression bar 7 to vertical with bus-bar 2, make ground stud between U-shaped hook 10 and electric interface 5, U-shaped hook 10 cover hangs over outside ground stud, and locating convex block 15 is near the bolt hole outside ground stud, and lead 13 cuts the bolt hole inside ground stud.Rotate depression bar 7 to bus-bar 2 direction, the distance of U-shaped hook 10 and electric interface 5 is reduced gradually.After U-shaped hook, ground stud, electric interface are all fitted, spring 11 starts compression, and spring force acts on movable axis 8 and produces two effects, and one shows as contact, and another shows as depression bar applying active force upwards.Be rotated further depression bar 7 and cross critical localisation, be i.e. the position of depression bar 7 and U-shaped hook 10 conllinear, the active force that spring 11 pairs of depression bars 7 apply becomes downwards, and this active force makes depression bar 7 be pressed against on bus-bar 2, and device forms self-locking.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
