Abstract

The invention discloses an improved grounding device. The improved grounding device comprises a substrate, wherein a rod body is fixedly connected to the bottom of the substrate; a cone is integrally formed at the bottom of the rod body; a sleeve is fixedly arranged below two sides of the substrate; a notch is formed in the periphery of the sleeve; an expansion cone is arranged below the sleeve; a threaded rod is movably connected to the top of the expansion cone and sequentially passes through the sleeve and the substrate; a spacer is movably connected to the threaded rod in a sleeving manner; a screw cap is connected to the top end of the threaded rod via a screw thread; a wire holder is fixedly arranged at the top of the substrate; a through hole is formed to pass through the top of the wire holder; a bolt is inserted into the through hole and connected to the through hole via a screw thread; a pressing plate is movably connected to the lower end of the bolt. Through expansion of the sleeve, the improved grounding device and the ground are well fixed, and the disabling of a grounding function is avoided to a great extent, so that the safety of people's life and property is guaranteed.

Description

A kind of follow-on earthed system
Technical field
The present invention is specifically related to a kind of follow-on earthed system, belongs to electrical equipment technical field.
Background technique
Along with improving constantly of socioeconomic development and enterprise's level of production, occurred various electrical equipment on the market, and the electrical equipment in each family is also on the increase, especially in factory, various machinery all needs to use electric power, in order to improve the safety in utilization of electrical equipment and machinery, most electrical equipment and machinery all need to carry out ground connection to shell, in electrical equipment and machinery ground connection operation process, usually need to use earth rod, the earth rod used at present mostly is a single metal bar, but current used earth rod is a single metal bar, thus be easy to cause loosening of earth rod in Long-Time Service, simultaneously current used earth rod its can not realize good contact with the earth, be easy to the inefficacy causing grounding function, after grounding function lost efficacy, once there is leaky in electrical equipment and machinery, just do not have leakage protection, the even security of the lives and property of entail dangers to people.
Summary of the invention
For the problems referred to above, it is simple that the technical problem to be solved in the present invention is to provide a kind of structure, practical, and earth rod and ground can be made to obtain good fixing, ensure not loosen in Long-Time Service, earth rod and the follow-on earthed system greatly realizing good contact can be improved simultaneously.
Follow-on earthed system of the present invention, comprises substrate; Described base plate bottom is fixedly connected with barred body; Centrum has been made into integration bottom described barred body; Described substrate down either side is fixedly installed sleeve; Described sleeve surrounding offers notch; Expansion centrum is provided with below described sleeve; Described expansion centrum top movable is connected with screw rod; Described screw rod runs through sleeve successively and substrate is arranged; On described screw rod, movable sheath is connected to pad; Described screw tip has been threaded connection nut; Described substrate top is fixedly installed wiring base; Described wiring base top is run through and is provided with through hole; Be plugged with bolt in described through hole, and bolt is connected with through hole by screw thread; Described bolt lower end is connected with pressing plate.
Further, stiffening rib has been made into integration outside described barred body.
Further, described stiffening rib is provided with multiple, and arranges around barred body.
Further, the lower end of described expansion centrum is set to arc-shaped.
Further, described wiring base inside bottom is set to arc-shaped.
Beneficial effect of the present invention: a kind of structure of the present invention is simple, practical, earth rod and ground can be made to obtain good fixing, ensure not loosen in Long-Time Service, earth rod and the follow-on earthed system greatly realizing good contact can be improved simultaneously; When installing of the present invention, offer the hole that three correspond respectively to sleeve and barred body first on the ground, and the degree of depth corresponding to the hole of barred body to be applicable to the length of barred body; Then barred body of the present invention is inserted in the hole corresponding with barred body, and makes sleeve also be inserted in the hole corresponding with sleeve; Then the nut be arranged on screw rod is tightened by spanner, make expansion centrum increase, when expanding centrum and barrel contacts, expansion centrum can enter into sleeve inner under the effect of screw rod, thus sleeve is expanded outwardly, realization is fixing with the hole offered before; Finally ground wire is plugged on wiring base inside, and by turning bolt, pressing plate is moved down, fixing of the ground wire that achieves a butt joint; The present invention is by the expansion of sleeve, the present invention and ground is made to realize good fixation, prevent the present invention from Long-Time Service, occurring the phenomenon loosened, the present invention simultaneously by arranging stiffening rib on barred body, barred body is made to obtain good contacting with the earth, avoid the inefficacy of grounding function to a great extent, thus ensure that the security of the lives and property of people.
Accompanying drawing explanation
For ease of illustrating, the present invention is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present invention.
