Groove, 6 is elastic force claw, and 7 is lock tube female thread, and 8 is lock tube external screw thread, and 9 is spanner fixed pan, and 10 slot for cross, and 11 are
Electric energy meter, 13 is ammeter installation portion, and 14 is distribution board, and 15 is ammeter box, and 16 fix screw for distribution board.
Detailed description of the invention
This utility model is not limited by following embodiment, can come with practical situation according to the technical solution of the utility model
Determine specific embodiment.
In this utility model, for the ease of describing, the description of the relative position relation of each parts is all according to description
The Butut mode of accompanying drawing 1 is described, such as: the position relationship of forward and backward, upper and lower, left and right etc. is based on Figure of description
Butut direction determine.
Below in conjunction with embodiment and accompanying drawing, this utility model is further described:
As shown in accompanying drawing 1,2, this electric energy meter mounting screw connection includes fixing screw, screw thread lock tube 1 and locking spiral shell
Female 2, fixing screw includes that head of screw 3 and screw rod 4, screw rod 4 right-hand member are connected as a single entity with head of screw 3 left end, and screw rod 4 has on left side
Point lobe groove 5 no less than one, the opening of point lobe groove 5 to the left and makes screw rod 4 left part form the elastic card that can open laterally
Pawl 6, screw rod 4 external stability is provided with screw thread lock tube 1, the inwall of screw thread lock tube 1 has and can match with screw rod 4 outside screw
Lock tube female thread 7, there is lock tube external screw thread 8 in the outside of screw thread lock tube 1 is installed with lock nut by lock tube external screw thread 8
