The technical problem solved by the utility model is to provide an improvement of the metal wire conduit coupling device which dispenses with the metric screw thread and a screw thread forming device, and has the advantages of time saving, labor saving, cost reducing, and labor intensity of workers reducing. The technical proposal is that the metal wire conduit coupling device is provided with a sleeve with two ends open, a circle of grooves are arranged in the center part of the two hatches on the wall of the sleeve, the grooves are distributed around the sleeve and sinks in the inner wall direction, the wall of the sleeve is provided with a fissure which is arranged in the axle direction of the sleeve and is communicated with the two hatches on the sleeve ends, the grooves can be replaced by a plurality of sunken points, and the metal wire conduit coupling device is further provided with an assembly of two blade type anchor ears and a plurality of bolts or an assembly of one blade type anchor ear and a plurality of anchor ear bolts.
Description
Technical field
The utility model relates to a kind of metal wire pipe connection, the pre-buried power in particularly building, decorateing, the jockey of communication spool.
Background technology
Metal power spool in the building and communication spool must couple together the spool of fixed length by the designing requirement location pre-buried when wiring.The general spool method of attachment of adopting during construction at present is that two conduit end of butt joint are attacked screw thread, then these two spools is screwed in the joint of a same specification.Because the spool One's name is legion in the building, spool has the specification of many kinds of different thicknesses sizes again, with this kind method very big workload is just arranged, and also need be equipped with the instrument of attacking the system screw thread of all size.Not only take a lot of work, time-consuming, working strength of workers is big, and cost is also high.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of improvement of metal wire pipe connection is provided, this device should have does not need to attack the system screw thread, saves the tap control equipment, saves time, the saving of labor, cost is low and the advantage that reduces labor strength.
The technical scheme that the utility model proposes is: the metal wire pipe connection, the sleeve pipe that a both ends open is arranged, position placed in the middle on the tube wall of this sleeve pipe between both ends open is shaped on a circle groove, this groove is along the circumferential directions of sleeve pipe and recessed to the inwall direction of sleeve pipe, and be shaped on the cracking seam on the tube wall of this sleeve pipe one, this cracking seam is communicated with along the axial arranged of sleeve pipe and with the sleeve pipe openings at two ends.
Also available several concave points of described groove substitute, and these concave points are uniformly distributed on the whole circle position of described groove.
Described metal wire pipe connection also is furnished with two chip anchor ears and the combination of some screws.
Described metal wire pipe connection also is furnished with a chip anchor ear and some anchor ear screw combinations.
The utility model only needs two spools are inserted sleeve pipe in use, adds at most that perhaps the stubborn more several screws of anchor ear can connect two spools.Very simple, convenient, only need single can the operation; Need not attack the system screw thread fully, save high-intensity system screw thread work and the various tap control equipment of attacking, save a large amount of operating times, significantly improve productivity ratio, reduce working strength of workers, building cost also greatly reduces.In addition, groove on the sleeve pipe of this device or concave point can be avoided the online tubular axis of sleeve pipe the port of slippage spool can also make two spools that connected concentric automatically to moving after spool connects, have be connected firmly, high reliability features.
Description of drawings
Fig. 1 is the connection diagram of sleeve pipe of the present utility model.
Fig. 2, Fig. 3 are respectively the front view and the left views of sheet anchor ear of the present utility model.
Fig. 4 is the schematic diagram of anchor ear screw combinations of the present utility model.
Embodiment
As shown in Figure 1, this metal wire pipe connection has the sleeve pipe 1 of an axial both ends open, and this sleeve pipe generally can be formed by the sheet metal punching out.Position placed in the middle on the tube wall of this sleeve pipe between both ends open is shaped on a circle groove 2, and this groove is along the circumferential directions of sleeve pipe and to the inwall direction of sleeve pipe recessed (the formed space plane of bottom land of this circle groove is basic vertical with the casing axis line); And be shaped on cracking seam 3 on the tube wall of this sleeve pipe one, this cracking seam is communicated with along the axial arranged of sleeve pipe and with the sleeve pipe openings at two ends.By this figure also as can be known, on internal surface of sleeve pipe, it is outstanding that groove 2 forms a circle; Spool 8 and two the open-ended insertions of spool 9 from sleeve pipe, the port locations of two spools can keep two spools concentric in the formed outstanding position of internal surface of sleeve pipe upper groove automatically.
Also available several concave points of above-described groove (2) substitute.These concave points are uniformly distributed on the whole circle position of described groove, and formation is outstanding on internal surface of sleeve pipe, has the identical effect of described groove (2).The punching out of concave point is also more simple.
For the spool of all size, correspondingly is furnished with the sleeve pipe of all size; Generally speaking, the internal diameter of sleeve pipe should be slightly smaller than the external diameter of the spool of corresponding specification, makes connection more solid and reliable.
As long as the utility model will treat that in use wire barrel inserts corresponding sleeve pipe, it is big just to the certain chucking power of spool generation that the cracking of sleeve pipe sews the conduit end support, and for thinner spool, this power is enough; For thicker spool, the chip anchor ear can be installed outside sleeve pipe, increase chucking power.
By Fig. 2 and Fig. 3 as can be known, the structure of chip anchor ear 4 comprises an arc surface 4-1 less than semicircle, and connect end face 4-2 from the two ends of the circumferencial direction of this arc surface towards extend two of of mutual rightabout, this arc surface 4-1 can match with the sleeve pipe outer circumference surface, these two connection end face 4-2 are in same space plane substantially, and are shaped on several screw holes 4-3 on the connection end face.When using this anchor ear, with two anchor ears (arc surface is relative) obvolvent sleeve pipe, screw combination (screw, nut and pad) is then passed and fastening nut the screw 4-3 from the connection end face of two anchor ears respectively, thereby makes the anchor ear clamp sleeve.
Anchor ear screw combinations shown in Figure 4 comprises that an anchor ear screw rod 10 reaches and the nut 10-1 and the pad (omission of pad view) of the threads engaged of two ends of this screw rod.With a sheet anchor ear obvolvent sleeve pipe, use some anchor ear screw rods (general available three anchor ear screw rods) to divide to stride sleeve pipe and pass the screw hole on the sheet anchor ear then during use, fastening nut gets final product.
In addition, when pre-buried connection, the sleeve pipe cracking seam place opening part between the anchor ear that should stagger.
