Abstract
The utility model relates to a spiral line parallel groove clamp, including upper cover and base, the upper cover corresponds two inside tight chambeies of clamp that form with the base, and the rifling in tight chamber of clamp is the helix, the upper cover sets up a set of through hole with the base middle part is relative at least to supply the bolt to pass and couple together upper cover and base. The utility model discloses simple structure need not the specialized tool operation and obtains the wide application, through reforming transform the back to the parallel groove clamp, can reduce the contact resistance of wire and parallel groove clamp, increases the through-flow capacity, increases mechanical strength to reduce the emergence of accident, improve the reliability of power supply.
Description
Technical Field
The utility model belongs to the technical field of transmission line, concretely relates to spiral line parallel groove clamp.
Background
With the increasing power load, the requirement on the reliability of power supply operation is higher, so that the hardware with high use reliability, economy and practicability becomes an inevitable trend of a distribution line; on a distribution network line, a parallel groove clamp is one of most used hardware fittings, and the burning-out fault of a drainage wire is frequently caused by the influence of construction quality, the change of power load, the occurrence of various faults and the temperature of an operating environment.
The rifling of the clamping cavity in the upper cover and the lower base of the existing parallel groove clamp is a straight line. When the staff is in high altitude construction in the work progress, both hands need take steady parallel groove clamp for a long time, influence construction quality, and the staff just can turn round tight parallel groove clamp nut with the health slope through the safety belt, because the staff is in the influence of high altitude construction psychological factor, often can cause the phenomenon of tight can not turn round completely to the parallel groove clamp nut, leads to contact resistance too big, causes the reason of blowing the drainage wire.
Disclosure of Invention
To the weak point among the prior art, the utility model provides a spiral line parallel groove clamp.
In order to achieve the above purpose, the utility model discloses technical scheme as follows:
the utility model provides a spiral line parallel groove clamp, includes upper cover and base, the upper cover corresponds inside two tight chambeies of clamp that form with the base, and the rifling that presss from both sides tight chamber is the helix, the upper cover sets up a set of through hole with the base middle part is relative at least to supply the bolt to pass to be connected upper cover and base.
Has the advantages that: the utility model discloses simple structure need not the specialized tool operation and obtains the wide application, through reforming transform the back to the parallel groove clamp, can reduce the contact resistance of wire and parallel groove clamp, increases the through-flow capacity, increases mechanical strength to reduce the emergence of accident, improve the reliability of power supply.
Drawings
Fig. 1 is an exploded view of the present invention.
In the figure, 1-upper cover, 2-base, 3-bolt, 4-clamping cavity.
Detailed Description
The present invention is described below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
The utility model provides a spiral line parallel groove clamp, as shown in figure 1, includes upper cover 1 and base 2, and upper cover 1 corresponds inside two clamping chamber 4 that form with base 2, and the rifling that presss from both sides clamping chamber 4 is the helix, and upper cover 1 sets up two sets of through holes with base 2 middle part is relative to supply bolt 3 to pass and is connected upper cover 1 and base 2.
Claims (1)
1. The utility model provides a spiral line parallel groove clamp, includes upper cover and base, its characterized in that: the upper cover and the base correspond to each other and form two clamping cavities, rifling of the clamping cavities is a spiral line, and at least one group of through holes are oppositely formed in the middle of the upper cover and the middle of the base so as to allow bolts to penetrate to connect the upper cover and the base.
