Abstract
The utility model discloses a ground rod with a mechanical locking function, mainly comprising an insulating tube 1 and an insulating rod 2 connected with the insulating tube 1, wherein the top end of the insulating rod 2 is sequentially provided with a spring energy storage bolt latch and a spring energy storage bolt tension device 3; the lower part of the insulating rod 2 is provided with a handle 4; the handle 4 is provided with an operating handle 5 and a lockset 6; the lockset 6 is internally provided with a limiting catch 7; the operating handle 5 is provided with a limiting bar 8; the limiting bar 8 is provided with a limiting groove 9; and the limiting catch 7 and the limiting groove 9 are connected in a clamping way. As seen from the figure 1, the handle 4 is also internally provided with a return spring 10 connected with the limiting catch 7. Through additionally arranging the lockset on the handle and by virtue of unlocking/locking the lockset, the operating handle is controlled to use. The ground rod is characterized by being simple in structure, convenient in installation and utilization, and free of damage to equipment, and by being safe as well as reliable. The ground rod has the locking function and ensures the safety of personnel while still being attractive in appearance.
Description
Technical field
The utility model belongs to the electrical safety apparatus, relates in particular to a kind of earth rod with mechanical latching function.
Background technology
Behind the electric power facility grid switching operation, need do safety measure, require again hanging earthing conductor of necessary first electrical verification according to rules.But under heavy operation task pressure, people might ignore this point, perhaps have idea of leaving things to chance, and directly hanging earthing conductor easily causes the person and equipment casualty accident.
At present, the multiple ground wire operating lever in existing public technology and the use only has type hand or semi-automatic, and the problem that occurs has following 3 points basically, and the one, manual operation is wasted time and energy; The 2nd, add not tightly at four meters and above high vacancy dress hanging ground-wire wire clamp, contact resistance is large, can not bear short-circuit current rush, can't guarantee the life security of high voltage electric power equip ment interruption maintenance; The 3rd, can not directly prevent the live ground wiring accident, can't guarantee operating personnel's life security.
The utility model content
In view of this, the utility model provides a kind of earth rod with mechanical latching function, has blocking function, in not electrical verification, does not perhaps pull up after the electrical verification in the situation of key and can't use earth rod, guarantees the person and device security with this.
The technical scheme that the utility model adopts is:
A kind of earth rod with mechanical latching function, mainly comprise insulated tube and the insulating bar that is connected with insulated tube, wherein, on the top of insulating bar, be disposed with that the spring energy-storage bolt-lock is buckled, spring energy-storage bolt take-up device, the insulating bar bottom is provided with handle, and handle is provided with operating handle, also is provided with lockset on the handle, be provided with spacing catch in the lockset, operating handle is provided with positive stop strip, and positive stop strip is provided with stopper slot, spacing catch and stopper slot clamping.
Also be provided with back-moving spring in the handle, back-moving spring is connected with spacing catch.
The good effect of technical solutions of the utility model is:
The utility model comes the use of control operation handle by installing lockset additional in handle portion by open locking; The utlity model has simple in structure, easy to install, do not damage equipment, safe and reliable characteristics, have blocking function, guarantee that personnel's safety is not lost again attractive in appearance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Embodiment
As seen from Figure 1, originally have the earth rod of mechanical latching function, mainly comprise insulated tube 1 and the insulating bar 2 that is connected with insulated tube 1, wherein, on the top of insulating bar 2, be disposed with that the spring energy-storage bolt-lock is buckled, spring energy-storage bolt take-up device 3, insulating bar 2 bottoms are provided with handle 4, handle 4 is provided with operating handle 5, also be provided with lockset 6 on the handle 4, be provided with spacing catch 7 in the lockset 6, operating handle 5 is provided with positive stop strip 8, positive stop strip 8 is provided with stopper slot 9, spacing catch 7 and stopper slot 9 clampings.
Be it can also be seen that by Fig. 1, also be provided with back-moving spring 10 in the handle 4, back-moving spring 10 is connected with spacing catch 7.
Claims (2)
