Abstract
The utility model discloses a grounding wire locking nut, which comprises a nut body. The top of the nut body is provided with a tightening block. The tightening block is fittingly connected with a rocking handle sleeve. The outer surface of the tightening block is in the form of a regular hexagonal prism, a regular quadrangular prism or a regular triangular prism. The tightening block is internally provided with a hole, and the diameter of the hole is slightly larger than the screw diameter of the nub body. According to the technical scheme of the utility model, the tightening block is welded on one side at the top of a general nut body and is fittingly connected with the rocking handle sleeve. A labor-saving lever structure is therefore formed by means of the rocking handle sleeve, so that the operation is convenient and labor-saving. Meanwhile, the situation in the prior art that the manually screwing operation is not tight in effect can be changed. Due to the shape design of the tightening block, the clamped type connection and the force application are facilitated, while the tightening block is not easily damaged. Moreover, the tightening block is internally provided with the hole, and the diameter of the hole is slightly larger than the screw diameter of the nub body. In this way, during the rotation of the nut, the defect that grounding wires cannot be tightly pressed due to the short stroke can be overcome. The grounding wire locking nut provided by the utility model is unique in creativity, simple in structure, firm and durable, and can also be disassembled freely. Therefore, grounding wires can be better and tightly pressed and locked.
Description
Technical field
The utility model belongs to electric armour clamp technical field, particularly a kind of ground wire locking nut cap.
Background technique
Ground wire locking nut cap is dead earth line and the part that generally uses, and can its quality that connects effect and quality is directly connected to ground wire safe good earth, is also related to staff's personal safety; Its raising that is also restricting efficiency of construction whether easy to use.At present, what utilization rate was higher in the industry is the butterfly nut of various models, but in its using process, exist larger defect: butterfly nut is generally selected the stubborn operating type of hand, operation inconvenience and screw cap easily damage, and this nut also has the drawback that is difficult for the ground wire compressing.Therefore need badly existing ground wire clamping nut improved accordingly, design a easy to use, the fastening piece of good connecting effect.Application number: 201220632810.5 Chinese patent discloses a kind of anti-drop structure of ground wire, relate to a kind of ground wire, pressing plate is passed through respectively at the two ends of ground wire, locking nut connects binding clip and earth clip, described binding clip and earth clip are same structure, upper end one side of described binding clip operating grip is provided with hook, in the joint of operating grip and hook, opposite side is provided with tip-lever support, push rod one end is through hinged by axle and tip-lever support after the flared channels of operating grip upper end, screw the tapped hole of the threaded stem attended operation handle endoporus lower end of handle, the polished rod of threaded stem upper end is through in the unthreaded hole in operating grip, described polished rod upper end withstands in push rod bottom surfaces.The anti-drop structure utilization of above-mentioned ground wire screws the polished rod of handle by locked push rod fixing, has effectively prevented coming off of binding clip or earth clip, more but its project organization improves, complex structure, and dismounting inconvenience, is unfavorable for promoting the use of.
Model utility content
The utility model object is to address the above problem, and provide a kind of easy to use, connect reliable ground wire locking nut cap.
To achieve these goals, the technical solution adopted in the utility model is: a kind of ground wire locking nut cap, and it comprises nut body, described nut bodies top arranges fastening block, the supporting crank handle sleeve barrel that is connected with of described fastening block.
Described fastening block outer surface is positive six prisms or four-prism or regular triangular prism.
Described fastening block inside arranges aperture and is slightly larger than the hole in described nut body spiral shell footpath.
The utility model is at a fastening block of the nut body top in six common sides or four directions one side welding, for synchronous described cap rotation and then the tightening ground wire of driving, and be the supporting crank handle sleeve barrel that is connected with of described fastening block, utilize described crank handle sleeve barrel to form laborsaving lever construction, easy to operate, change hand and twisted not tight present situation, the shape of described fastening block can be set to positive six prisms or four-prism or regular triangular prism as required, be convenient to the clamping application of force, and it is not fragile, only need to get final product convenient use according to the crank handle sleeve barrel of one of the dimensioned of post and its coupling, and described nut can be realized, and interchangeability is replaced and allotment, further, described fastening block inside arranges aperture and is slightly larger than the hole in described nut body spiral shell footpath, can prevent because stroke in described cap rotation process is compared with short and cannot compress ground wire.
The utility model intention uniqueness, simple in structure durable again, and dismounting is freely, is applicable to locking and fastens ground wire, guarantees reliable ground, generally promotes the use of than being easier to.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is a kind of structural representation of nut body described in the utility model;
Fig. 2 is use structural representation of the present utility model.
Embodiment
Specific embodiment one
As shown in Figure 1 and Figure 2, a kind of ground wire locking nut cap, it comprises nut body 1, described nut body 1 top arranges fastening block 2, the supporting crank handle sleeve barrel 3 that is connected with of described fastening block 2.
Described fastening block 2 outer surfaces are four-prism.
Described fastening block 2 inside arrange aperture and are slightly larger than the hole 4 in described nut body 1 spiral shell footpath.
Specific embodiment two
Be with the difference of specific embodiment one: described fastening block 2 outer surfaces are positive six prisms or regular triangular prism
The utility model is at a fastening block of the nut body top in six common sides or four directions one side welding, for synchronous described cap rotation and then the tightening ground wire of driving, and be the supporting crank handle sleeve barrel that is connected with of described fastening block, utilize described crank handle sleeve barrel to form laborsaving lever construction, easy to operate, change hand and twisted not tight present situation, the shape of described fastening block can be set to positive six prisms or four-prism or regular triangular prism as required, be convenient to the clamping application of force, and it is not fragile, only need to get final product convenient use according to the crank handle sleeve barrel of one of the dimensioned of post and its coupling, and described nut can be realized, and interchangeability is replaced and allotment, further, described fastening block inside arranges aperture and is slightly larger than the hole in described nut body spiral shell footpath, can prevent because stroke in described cap rotation process is compared with short and cannot compress ground wire.
