Abstract
The utility model relates to an electrical metal pipe joint, which is composed of a compression joint 1, compression nuts 2 and a clamping ring 3 with an opening and is also provided with an anti-loosing nut 5 which is used for fixing a metal joint on a terminal box 7. The utility model is characterized in that the clamping ring 3 with an opening installed in the nuts 2 is tightened centripetally under the extrusion of an inclined face at the back end of the nuts through screwing the compression nuts 2 on the compression joint 1; a metal wire tube penetrating through a metal joint is clamped tightly, and thus, the metal wire tube can perform the functions of connecting and fastening. The utility model has the advantages of possible and convenient operation, firm connection, economy, durability, fireproof, dampproof, little possibility of deformation or smash, etc. The utility model is suitable for installing and laying electrical wires and cable engineering of buildings, ships or other construction occasions.
Description
The utility model relates to a kind of connection element of electrician's spool; Specifically a kind of electrician's metallic pipe coupling.
Electrician's metallic pipe coupling is the coupling components of necessary outer layer metal protection spool in modern architecture, steamer or other construction occasion installation and laying wire, the cable work.
In the prior art, electrician's spool of above-mentioned occasion all is to adopt plastic tube or earthenware.This spool is extremely inconvenient in connecting operation, and connects also insecure.For example, the plastic tube easy deformation is unfavorable for fire prevention, and earthenware is then broken easily, and is difficult for connecting.Therefore these two kinds of spools all lack economy, durable and practical advantage.
The purpose of the utility model is at the above-mentioned state of the art, develops a kind of novel electrician's pipe joint with economy, durable, practical advantages.
Basic fundamental solution of the present utility model is design and makes and a kind ofly form electrician's metallic pipe coupling of an assembly by compression joint, compression nut and slotted collar, utilize this joint can the metal spool of different length is easy, link up securely.
Major advantage of the present utility model is can be according to the construction needs of laying-out, design and make the series of products of plurality of specifications, be beneficial to and the supporting use of the spool of different size, and it is simple and feasible to have operation, connects firmly, excellent results such as economy and durability, fire-proof and damp-proof, not yielding or fragmentation.
Accompanying drawing 4 is cutaway views of the compression joint 1 among Fig. 1;
The a of accompanying drawing 5, b are the schematic diagrames of the compression nut 2 among Fig. 1;
The a of accompanying drawing 6, b are the schematic diagrames of the slotted collar 3 among Fig. 1;
Accompanying drawing 7 is cutaway views of metal spool 4;
The a of accompanying drawing 8, b are the schematic diagrames of the stop nut 5 among Fig. 3.
Below by three embodiment, to specific embodiments of the present utility model and connect fastening principle and be elaborated:
Embodiment 1 (referring to accompanying drawing 1): it by compression joint 1, be sleeved on compression nut 2 on the compression joint 1, be arranged in the slotted collar 3 of compression nut 2 and be sleeved on the stop nut 5 of compression joint 1 other end that (Fig. 1 is not shown, can be referring to Fig. 3 and Fig. 8) form, wherein:
1, compression joint 1 is that the two ends diameter is different, and two ends all have externally threaded pipe collar shape.The length of wherein big footpath one end is beneficial to suit compression nut 2 to be advisable greater than 2/3rds of total length; At big path gathering point an annular flange is arranged,, compression joint 1 is fastened on (referring to Fig. 3) on the terminal box 7 in order to cooperate with the stop nut 5 that is sleeved on path one end.
2, the internal diameter of compression nut 2 has internal thread, in order to be sleeved on big footpath one end of compression joint 1; One end of compression nut 2 external diameters is the hexagon that radially protrudes, and is processed into trapezoidal section groove at hexagonal inwall, in order to hold slotted collar 3.
3, slotted collar 3 is periphery opening shape annulus to outer lug, in order to be sleeved between metal pipe line 4 and the compression nut 2.
Embodiment 2 (referring to accompanying drawing 2): its combining structure is substantially the same manner as Example 1, and just compression joint 1 wherein is a two ends equal diameters, and two ends have externally threaded pipe collar shape structure.It is circular-arc annular groove that a section is arranged at the axial middle part of compression joint 1.This compression joint can be linked together with the metal spool of two compression nuts 2 with the joint two ends.
Embodiment 3 (referring to accompanying drawing 3): compression joint 1 is that a two ends diameter has other pipe collar shape.The length of wherein big footpath one end is to be advisable greater than 2/3rds of total length.On the tube wall of big end, there is a device to hold out against the screw of screw 6, in order to the metal spool is held out against in the internal diameter of compression joint 1, at the phase accumulation of size diameter the bead of an annular is arranged, cooperate, compression joint 1 is fastened on the terminal box 7 in order to stop nut 5 with path threaded one end suit.
More than three embodiment, it connects principle all is by screwing the compression nut 5 on the compression joint 1, the slotted collar 3 that is contained in the nut 5 is entad tightened under the extruding on nut back end inclined-plane, the metal wire pipe clamp that is through in the metal joint is tight, connect and fastening effect thereby play.
Three above-mentioned embodiment, all selecting wall thickness for use is the Q195 thin-walled welding pipe of 1.6mm-2.2mm, through reining in the tandem product that main craft procedure such as hole, shaping, indent and rolled thread are made different size.
Claims (2)
1, a kind of electrician's metal wire pipe joint is characterized in that being made up of compression joint (1), compression nut (2) and slotted collar (3), wherein:
(1) compression joint (1) can be appointed from following three kinds of structures and selected one:
1. the two ends diameter is big or small different, and all has externally threaded pipe collar shape at two ends, and the bead of an annular is arranged at the phase accumulation of size diameter;
