Description
Technical field
The utility model 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 problems to be solved in the utility model is to provide a kind of structure, 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.
Follow-on earthed system of the present utility model, 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.
The utility model beneficial effect: a kind of structure of the present utility model 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 the utility model, 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 utility model 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 utility model is by the expansion of sleeve, the utility model and ground is made to realize good fixation, prevent the utility model from Long-Time Service, occurring the phenomenon loosened, the utility model by arranging stiffening rib on barred body simultaneously, 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 utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model.
