Abstract
The utility model relates to a thread joint for an electrical guide tube box, comprising a tube head and nuts. The utility model is characterized in that the tube head is the sleeve joint external thread tube head; a block shoulder is arranged on the inner end head of tube head threads on which the nuts are arranged; the six corners of each nut form claw shapes in the direction of the block shoulder; each nut is the hexagonal nut or the octagonal nut. The utility model has the advantages of no expansion for the tube head and firm connection, being suitable for the connection of sleeve joint type electric guide tube boxes.
Description
The utility model relates to a kind of electric conduit connector.Particularly a kind of socket joint type electric conduit and the connector of managing box.
When architectural electricity is installed, usually need to lay electric conduit, and electric conduit and electric pipe box coupled together, the joint of existing electric conduit pipe box adopts the heavy cup formula to be threaded, this pipe joint by enlarge at link, and female tube head and heavy cup formula inner nut form, processing inconvenience connects insecurely, is difficult to guarantee to manage the electrical continuity of box.
The purpose of this utility model provides a kind of electric conduit and the nipple of managing box, guarantees to lead the quality of connection of tube and tube box.
The technical solution of the utility model is: this electric conduit pipe box nipple, comprise tube head, nut, it is characterized in that: tube head is a socket external screw thread tube head, on the inner termination of tube head screw thread shoulder block is arranged, nut is arranged on the screw thread, and the hexagonal of nut is claw-like to the shoulder block direction.
Above-mentioned nut is hexagon or octagon nut.
The course of work of the present utility model: will manage box and be clipped between the shoulder block and nut on the tube head, will manage box and firmly clamp the back fastening nut, the pressure of tightening that hexagonal is the claw type nut concentrates on 6, makes pawl point built-in box wall 0.1～0.3mm, has guaranteed quality of connection.
The utility model has the advantages that: tube head is not expanded, no internal thread, and handling ease, nut embeds with pipe box multiple spot, is connected firmly, and quality is good, guarantees electrical continuity.Be applicable to the connection of socket joint type electric conduit pipe box.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
