Abstract
Lightning grounding stick line is from lock union end belongs to the lightning protection device field. Current earth bar line clamping deformation hookup mode exists operates inconvenient, the unable defect that the secondary used of dismantling. The utility model discloses a hookup terminal body, the setting of hookup terminal body one end is used for the hollow tube portion of appearance and dress earth bar line, offer at least one the axial gap of running through on the pipe wall of hollow tube portion, the pipe wall that makes hollow tube portion has certain elasticity, can radial expansion or shrink and reset, hollow tube portion surface is provided with one section at least taper thread, the outer cover at least of taper thread is equipped with the nut of a correspondence, through the nut in the ascending swivelling movement of hollow tube portion's axle, realize the shrink or the expansion of the pipe wall of hollow tube portion. The utility model discloses couple convenient operation and can dismantle the secondary and use.
Description
Technical field
The utility model belongs to lightning protection device field, especially relevant with a kind of lightning protection rod line self-locking type joint Terminal.
Background technology
Lightning protection rod, with conventional joint Terminal is connected between earth connection or between earth connection with earth connection, can reach longer length.The structure of traditional lightning protection rod line coupling arrangement adopts one end to arrange hollow pipe, earth rod line is installed in hollow pipe inner chamber, pipe wrench clamping hollow pipe is used to make hollow pipe be out of shape indent, realization is fixing with excellent line, such connecting mode operation inconvenience, and non-dismountable after distortion clamping, cannot use by secondary, change inconvenience and cause waste of material.
Utility model content
The purpose of this utility model is intended to overcome the operation inconvenience that existing earth rod line pinching deformation connecting mode exists, the defect cannot dismantling secondary use, provides the lightning protection rod line self-locking type joint Terminal that a kind of join operation is convenient, can dismantle secondary use.
For this reason, the utility model is by the following technical solutions: lightning protection rod line self-locking type joint Terminal, comprise joint Terminal body, joint Terminal body one end arranges the hollow tube portion for being installed in earth rod line, it is characterized in that, the tube wall in described hollow tube portion offers at least one axial slits run through, the tube wall in hollow tube portion is made to have certain elasticity, can radial dilatation or contraction reset, described hollow tube portion outer surface is provided with at least one section of taper thread, taper thread is at least set with a corresponding nut outward, by nut in hollow tube portion axially in rotary moving, realize contraction or the expansion of the tube wall in hollow tube portion.
When the utility model uses, earth rod line is installed in the inner chamber in hollow tube portion, described locking nut screws in tapered thread, move axially from the less one end of tapered thread diameter to the larger one end of diameter, hollow tube portion tube wall is shunk, thus the earth rod line that links closely makes it mutually to be connected, and reach the object of self-locking; If need dismounting, as long as by nut from the larger one end of tapered thread diameter to diameter less one end turn, the tube wall expansion in hollow tube portion, itself and earth rod line are thrown off, and earth rod line can unload.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
The outer surface in described hollow tube portion is provided with the two sections of tapered threads be spaced a distance, and in every section of tapered thread, a corresponding suit nut, makes the tube wall in hollow tube portion more even on whole hollow tube minister degree to the throw-on pressure of earth rod line.
The quantity of described axial slits is four, makes the tube wall shrinkage expansion in hollow tube portion even, better realizes fixedly holding tightly to earth rod line.
The utility model can reach following beneficial effect: arrange axial slits and tapered thread by hollow tube portion, realize the contraction of tube wall with nut screw connection or expand to reach holding tightly of earth rod line is connected or is unclamped, easy to operate, secondary can be loaded and unloaded use, and damage can not be caused to earth rod line surface, the useful life of earth rod line can be extended, decrease waste of material, reduce lightning protection cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises joint Terminal body, joint Terminal body one end arranges the hollow tube portion 1 for being installed in earth rod line, the tube wall in hollow tube portion 1 offers at least one axial slits run through 4, the quantity of axial slits 4 is four, make the tube wall shrinkage expansion in hollow tube portion 1 even, better realize fixedly holding tightly to earth rod line, hollow tube portion 1 outer surface is provided with at least one section of taper thread, the outer surface in hollow tube portion 1 is provided with the two sections of tapered threads 3 be spaced a distance, a corresponding suit nut 2 in every section of tapered thread 3, make the tube wall in hollow tube portion 1 more even in whole hollow tube portion 1 length to the throw-on pressure of earth rod line, taper thread is at least set with a corresponding nut 2 outward, by nut 2 in hollow tube portion 1 axially in rotary moving, realize contraction or the expansion of the tube wall in hollow tube portion 1, the outer surface in hollow tube portion 1 is provided with the two sections of tapered threads 3 be spaced a distance, a corresponding suit nut 2 in every section of tapered thread 3, make the tube wall in hollow tube portion 1 more even in whole hollow tube portion 1 length to the throw-on pressure of earth rod line.
When the utility model uses, earth rod line is installed in the inner chamber in hollow tube portion 1, locking nut 2 screws in tapered thread 3, move axially from the less one end of tapered thread 3 diameter to the larger one end of diameter, hollow tube portion 1 tube wall is shunk, thus the earth rod line that links closely makes it mutually to be connected, and reach the object of self-locking; If need dismounting, as long as by nut 2 from the larger one end of tapered thread 3 diameter to diameter less one end turn, the tube wall expansion in hollow tube portion 1, itself and earth rod line are thrown off, and earth rod line can unload.
