Abstract
The utility model discloses a kind of automatic telescopic experiment line apparatus, including shell (1), spring assembly and test wire (3)；The lateral surface of the shell (1) is equipped with portable handle (5), pedestal (4) and two limiters (2) for being separately positioned on shell (1) both sides；The spring assembly is mainly made of bearing and thick wind spring；The bearing is mounted on the internal centre position of shell (1), and thick wind spring is mounted on bearing inner race；The middle section of the test wire (3) is wrapped on bearing, and shell (1) is stretched out in the both ends of test wire (3) by the limiter (2) of shell (1) both sides respectively, when test wire (3) need not carry out flexible, limiter (2) blocks test wire (3), and test wire (3) is fixed.The utility model is simple in structure, appearance is neat and artistic, can extend test wire service life, time saving and energy saving, improve work efficiency, reduce operating risk.
Description
Technical field
The utility model is related to a kind of utensils of retractable cable, the especially reel of reaying protection test line.
Background technology
Relay protection is great to the safe and effective influence on system operation of electric system, and it is one to carry out periodic inspection to protective device
Essential work.The method for arranging relay protection test line at present is to use line packet bulk cargo, but place test using line packet
Instrument wiring is be easy to cause since number of conductors is excessive, and conducting wire is made mutually to wind, be deposited in it is also all in tumble in test wire packet,
It is when taking out suitable wiring and manual take-up time-consuming and laborious, and long-term exposed use the longevity in outer serious wear, test wire
Life substantially reduces and operating risk is high.
Utility model content
The deficiency of the utility model in view of the prior art provides a kind of automatic telescopic experiment line apparatus and solves above-mentioned ask
Topic.
The utility model is realized in this way：
A kind of automatic telescopic experiment line apparatus, including shell, spring assembly and test wire；The lateral surface of the shell is set
There are portable handle, pedestal and two limiters for being separately positioned on shell both sides；The spring assembly mainly have bearing and
Thick wind spring composition；The centre position of the bearing installation inside the housing, thick wind spring are mounted on bearing inner race；The experiment
The middle section of line is wrapped on bearing, and shell is stretched out in the both ends of test wire by the limiter of shell both sides respectively,
When test wire need not carry out flexible, limiter blocks test wire, and test wire is fixed.
In the present invention, the thick wind spring of setting can provide the power that test wire recycles automatically, i.e. bearing is rolled up with thick
Spring cooperates, and smooth, wear-resisting and power is sufficient when use；Test wire can be fixed limit in the limiter of setting, can
It adjusts test wire and uses length, reach the function of one outlet of a drawing, one recycling of a drawing.
The utility model further illustrates, when the test wire is two or more, using the test wire of different colours.It presses
Color separated time is identified as both-end, does not have to when test clerk wiring worry whether test wire is same piece-root grafting line, only need to be according to examination
The color for testing line carries out wiring, simple and convenient.
The utility model further illustrates that the shell uses plastic shell.Plastic shell intensity is high, pressure resistance is resistance to falls,
It is effectively protected test wire.
The beneficial effects of the utility model：
The utility model is simple in structure, easy to use, durable, and overall appearance is clean and tidy, beautiful, and can extend test wire makes
It is time saving and energy saving, work efficiency is high and effectively reduces operating risk with the service life.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Shell 1, limiter 2, test wire 3, pedestal 4, portable handle 5.
Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment：
As shown in Figure 1, a kind of automatic telescopic tests line apparatus, including shell 1, spring assembly and test wire 3；Described is outer
The lateral surface of shell 1 is equipped with portable handle 5, pedestal 4 and two limiters 2 for being separately positioned on 1 both sides of shell；The spring
Device is mainly made of bearing and thick wind spring；The bearing is mounted on the centre position inside shell 1, and thick wind spring is mounted on axis
Hold inner ring；The middle section of the test wire is wrapped on bearing, and the both ends of test wire pass through 1 both sides of shell respectively
Limiter 2 stretches out shell 1, and when test wire need not carry out flexible, limiter blocks test wire, and test wire is fixed.
The test wire is the test wire of four different colours.The shell 1 uses plastic shell.
Obviously, above-described embodiment illustrates the utility model example just for the sake of clear, and not to implementing
Restriction.For the those of ordinary skill in the field, other not similar shapes can also be made on the basis of the above description
The variation or variation of formula.There is no need and unable to all embodiment party's formulas with exhaustion.And it thus amplifies out aobvious and easy
Among the variation or variation seen are still in the scope of protection of the utility model.
