Abstract
The ground terminal mechanism with key lock that the utility model discloses a kind of, including earth stud (1), earth stud (1) is equipped with the nut (2) of fastening ground line (7), lockhole (3) are additionally provided on earth stud (1), the lock (4) for preventing nut (2) from screwing out is equipped in lockhole (3), the key of lock (4) has latching logic.The utility model has the characteristics that take out stitches, and logic is rigorous, maloperation and security risk can be prevented lesser.In addition, the utility model also have the characteristics that it is locking and antifouling.
Description
Technical field
The utility model relates to a kind of earthing or grounding means, especially a kind of ground terminal mechanism with key lock.
Background technique
In the work progress of various engineerings, in order to guarantee Electrical Safety, transmission line of electricity needs to be grounded.Existing ground connection dress
The thickness according to ground line is set, two classes are generally divided into.For thinner ground line, when ground connection usually pass through have it is axial deep
The bolt of slot, then compressed with nut；For thicker ground line, ground connection is then to be wound on bolt, and compressed with nut.On
The two kinds of earthing or grounding means stated all are very easy to when taking out stitches, and there are the possibility of maloperation.If it is improper that operator links up,
There is the case where band ground wire power transmission, it is more likely that generate security risk.Therefore, there is logic letter of taking out stitches in existing earthing or grounding means
List is easy to produce maloperation and there are problems that security risk.
Utility model content
The ground terminal mechanism with key lock that the purpose of the utility model is to provide a kind of.The utility model, which has, to be torn open
Line logic is rigorous, can prevent maloperation and the lesser feature of security risk.
The technical solution of the utility model includes: a kind of ground terminal mechanism with key lock, including earth stud, earth stud
It is equipped with the nut of fastening ground line, lockhole is additionally provided on earth stud, is equipped with the lock for preventing nut from screwing out, the key of lock in lockhole
Spoon utensil has latching logic.
In a kind of ground terminal mechanism with key lock above-mentioned, the earth stud is arranged with anti-between lock and nut
Loose sleeve, one end that sleeve retainer is contacted with nut are equipped with the through slot of at least twice axial direction.
In a kind of ground terminal mechanism with key lock above-mentioned, the nut is wing nut.
Compared with prior art, the utility model limits the lock of nut, while the key locked by being arranged on earth stud
Spoon participates in latching logic, namely only works as the key that lock could be obtained under power blackout situation, and then take out stitches.The utility model as a result,
It avoids accidentally to tear ground wire open in logic using and with maloperations such as ground wire power transmissions, significantly reduces security risk, meet work
The anti-principle of the five of journey.
Moreover, on the one hand the tube-in-tube structure of the utility model can resist nut, prevent nut loosening from generating safety
On the other hand hidden danger can cover nut and ground line, reach anti-fouling effect.
Further, compressing ground line nut makes more convenient operation using wing nut.
To sum up, the utility model has the characteristics that take out stitches, and logic is rigorous, maloperation and security risk can be prevented lesser.This
Outside, the utility model also has the characteristics that locking and antifouling, and the utility model has the advantages of simple structure, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of sleeve retainer.
Appended drawing reference: 1- earth stud, 2- nut, 3- lockhole, 4- lock, 5- sleeve retainer, 6- through slot, 7- ground line.
Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment: a kind of ground terminal mechanism with key lock, including earth stud 1, earth stud 1 are equipped with fastening and connect
The nut 2 of ground wire 7 is additionally provided with lockhole 3 on earth stud 1, is equipped with the lock 4 for preventing nut 2 from screwing out in lockhole 3, locks 4 key tool
There is latching logic.
The earth stud 1 is arranged with sleeve retainer 5 between lock 4 and nut 2, sleeve retainer 5 contacted with nut 2 one
End is equipped with the through slot 6 of at least twice axial direction.
The nut 2 is wing nut.
Working principle:
It will punch in the middle part of earth stud 1, after ground line 7 is connect with earth stud 1, compressed using wing nut, and
4 are locked on cavity, the key for locking 4 participates in key lock logic.Latching logic is the mechanism by conditioning each other and linking to reach
To the purpose successively acted, namely only work as the key that lock 4 could be obtained under power blackout situation, and then take out stitches.To which this is practical new
Type solves the problems, such as accidentally to tear ground wire open and with maloperations such as ground wire power transmissions.
As shown in Fig. 2, sleeve one end corresponding with nut 2 on bolt has the through slot 6 of multiple tracks axial direction.Sleeve is pushed,
Make sleeve ends deformation, diffusion, to envelope nut 2 and ground line 7, is locked, achieved the effect that locking and antifouling with lock 4.
