Abstract
The utility model discloses a quick earthing device of lock formula, including the earthing pole, the earthing pole top is provided with the fixed connection seat, fixed connection seat matching has can be provided with the public head of ground connection rather than the swing joint seat of mutual lock in the swing joint seat, be provided with in the fixed connection seat and match and the female head of telescopic ground connection with the public head of ground connection, be provided with the magnet of inter attraction on the terminal surface that swing joint seat and fixed connection seat docked mutually. The beneficial effects of the utility model are that: when needs ground connection, can make things convenient for and carry out ground connection fast, compare traditional ground connection method moreover, still have the contact and well, be difficult for droing and destroying the high advantage of security.
Description
Technical field
The utility model relates to a kind of buckle-type Rapid grounding device.
Background technology
At present, when station works, need to use the electric tools such as electric welding machine, after requiring the necessary reliable ground of electric power tool shell, can use.Sometimes need to prevent electrostatic induction with individual safety wire, the connected mode of individual's safety wire and electric power tool shell earth connection is generally and screws with two screws, two screws will be turned on and tighten to each use earth connection all, waste time and energy, and earth connection connects insecure, easily come off, also easily destroyed by people, fail safe is not high.
Summary of the invention
For solving above technical deficiency, it is quick and convenient that the utility model provides a kind of ground connection, do not allow caducous buckle-type Rapid grounding device.
The utility model is realized by following measures:
A kind of buckle-type Rapid grounding device of the present utility model, comprise earth electrode, described earth electrode top is provided with fixed connecting base, described fixed connecting base coupling has the active connecting base that mutually can fasten with it, ground connection male is provided with in described active connecting base, be provided with in described fixed connecting base and match and telescopic ground connection female with ground connection male, the end face that active connecting base and fixed connecting base connect is provided with the magnet attracted each other.
Above-mentioned ground connection female is the circular arc contact plate of outward opening, described fixed connecting base bottom transverse is provided with guide cylinder, described guide cylinder opening is towards the back side of contact plate, and be horizontally arranged with spring in guide cylinder, described spring one end connects the back side of contact plate, and the spring other end connects earth electrode.
The port of above-mentioned guide cylinder is provided with adduction edge.
The beneficial effects of the utility model are: when needs ground connection, can carry out ground connection quickly and easily, and compare traditional earthing method, also have contact good, difficult drop-off and destruction, the advantage that fail safe is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional view after active connecting base of the present utility model and fixed connecting base dock.
Wherein: 1 earth electrode, 2 fixed connecting bases, 3 active connecting bases, 4 ground connection males, 5 magnet, 6 contact plates, 7 guide cylinders, 8 springs.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, 2, a kind of buckle-type Rapid grounding device of the present utility model, comprise earth electrode 1, earth electrode 1 top is provided with fixed connecting base 2, fixed connecting base 2 coupling has the active connecting base 3 that mutually can fasten with it, be provided with ground connection male 4 in active connecting base 3, be provided with in fixed connecting base 2 and match and telescopic ground connection female with ground connection male 4, the end face that active connecting base 3 and fixed connecting base 2 connect is provided with the magnet 5 attracted each other.Ground connection female is the circular arc contact plate 6 of outward opening, fixed connecting base 2 bottom transverse is provided with guide cylinder 7, and guide cylinder 7 opening towards the back side of contact plate 6, and is horizontally arranged with spring 8 in guide cylinder 7, spring 8 one end connects the back side of contact plate 6, and spring 8 other end connects earth electrode 1.The port of guide cylinder 7 is provided with adduction edge, improves the intensity of guide cylinder 7, avoids clashing into and cause tearing of guide cylinder 7.
Under non-mated condition, spring 8 is apical grafting ground female, namely contact plate 6 outwards, and guide cylinder 7 can play guide effect, prevent spring 8 from bending, as shown in Figure 2, when mated condition, first ground connection male 4 contacts contact plate 6, then ground connection female can be compressed by ground connection male 4 backward, now spring 8 is compressed, thus ground connection male 4 one extruding forces given by spring 8, and what ground connection male 4 was contacted with contact plate 6 is tightr.There is the contact head of circular arc ground connection male 4 end, and contact plate 6 place diameter of a circle is greater than contact head place diameter of a circle.Ground connection male 4 can be made so more easily to locate, prevent it from bending occurring or deflects away from.Simultaneously contact plate 6 withstands by the port of guide cylinder 7, prevents contact plate 6 from rocking, thus ground connection female is contacted with ground connection male 4 more stable.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection range that also should be considered as this patent.
