Description
Technical field
The utility model relates to ground connection relevant device, holds installing device with particularly relating to a kind of earth connection.
Background technology
As everyone knows, a large amount of power transformations is equiped with in transformer station, the alternating-current electric equipment of transmission and disttrbution and the electric equipment of other purposes, in order to ensure that these electric equipments normally work and security protection, must by these electric equipments ground connection safely and reliably, earth connection ground end installing device (as shown in Figure 1) conventional at present, comprise the fixed part connecting and need grounding apparatus, described fixed part has external screw thread and lockhole, grounding copper nose is fixed on fixed part by clamp nut, then lockhole is pinned by lockset, because requirements of one's work, such as measurement of Grounding Resistance etc., this earth connection ground end installing device needs frequent dismounting, when dismantling, need to open lockset, screw off clamp nut, take out copper nose, then when loading onto, need again to put copper nose, screw in nut, lock lockset, such operational sequence is too many, and clamp nut very easily gets rusty after wind and weather, cause dismantling.
Utility model content
For holding installing device Problems existing in above-mentioned prior art, the utility model provides that a kind of dismounting operation is few, easy to operate, hold installing device the earth connection of clamping fastener earth connection.
The technical scheme that problem to be solved in the utility model is taked is: earth connection ground end installing device, comprise fixed part and clamping part, described fixed part arranges projection, the cross section of described projection is octagon, one end of fixed part is fixed on to be needed on grounding apparatus, the other end of fixed part is provided with lockhole, described clamping part comprises clamping chamber, lockset can pin lockhole through clamping chamber, the forward annular in described clamping chamber is arranged at intervals with some claws, described claw is provided with fastening spring, described clamping cavity outer wall is provided with tension spring, the rear portion in clamping chamber is connected with copper nose and earth connection.
The utility model has the advantages that: 1, during dismounting earth connection ground end, the operation of dismounting clamp nut can be saved, can prevent clamp nut from getting rusty and causing not easy-to-dismount situation; 2, adopt the snap fit between claw and projection, and it is fastening functional, fast easy to operate to coordinate fastening spring and tension spring to make.
Accompanying drawing explanation
Fig. 1 be existing earth connection hold installing device structural representation,
Fig. 2 is using state cross-section structure of the present utility model ground schematic diagram,
Fig. 3 is Fig. 2 is A-A cross-sectional view.
In the drawings, 1, claw 2, fastening spring 3, clamping part 4, tension spring 5, lockhole 6, earth connection 7, copper nose 8, lockset 9, projection 10, clamping chamber 11, fixed part 12, need grounding apparatus.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with embodiment, the utility model is described in further detail with reference to the accompanying drawings below.
As Fig. 2, shown in 3, described earth connection ground end installing device, comprise fixed part 11 and clamping part 3, the cross section of clamping part and the form fit of fixed part, described fixed part is arranged projection 9, the cross section of described projection is octagon, one end of fixed part is fixed on to be needed on grounding apparatus 12, the other end of fixed part is provided with lockhole 5, described clamping part comprises clamping chamber 10, lockset 8 can pin lockhole through clamping chamber, the forward annular in described clamping chamber is arranged at intervals with some claws 1, claw is made up of the alloy material conducting electricity and elasticity is good, in order to promptly clamp projection, the outer inclined-plane of catching preferably mates with the outer inclined-plane of projection, described claw is provided with fastening spring 2, effect is ensure certain chucking power when clamping, described clamping cavity outer wall is provided with tension spring 4, effect is that clamping part is when being inserted in fixed part and taking out, keep certain elasticity, the elastic force of described tension spring should be greater than fastening spring, the rear portion in clamping chamber is connected with copper nose 7 and earth connection 6 by pad and bolt (not marking in figure).
The utility model in use, fixed part is inserted in the clamping chamber of clamping part, exerts oneself forward, due to the outer inclined plane shape of front end claw and the outer inclined-plane coupling of projection, claw can move rapidly on the inclined-plane of projection, and last under the clamping of fastening spring fastening clamp projection, in like manner, during dismounting, remove lockset, only outwards need external force a little, easily can take out clamping part, operating efficiency is compared original installing device and is greatly improved.
Above execution mode is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to specific embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
