Abstract
The utility model provides a pipe quick-opening flange connecting device, and belongs to the field of building pipes. By means of addition of a convex flange and a corresponding concave flange at the ends of pipes and addition of a mechanism capable of tightening the convex flange and the concave flange, the pipe quick-opening flange connecting device can achieve rapid opening and rapid locking. One end of the first pipe is provided with the concave flange, one end of the second pipe is provided with the convex flange, a boss of the convex flange is matched with a groove of the concave flange, the first pipe provided with the concave flange is sleeved with a tightening nut, one end of the tightening nut is clamped on the concave flange, the other end of the tightening nut is provided with internal threads, and the internal threads of the tightening nut are matched with external threads on the side wall of the convex flange. The pipe quick-opening flange connecting device is simple in structure and convenient to install and use, when connection is needed, only one convex pipe and one corresponding concave pipe are need to be aligned, then the tightening nut is screwed, and the ends of the two pipes can be firmly fastened together. If disassembly is needed, the two pipes can be separated easily by simply screwing the tightening nut reversely.
Description
Technical field
The utility model belongs to building pipe field.
Background technique
Various place that is applied in of pipeline is used, for the ease of transportation, the length of general pipe can be not oversize, the existence that so just needs pipe to connect, and be commonly used always, the linking that tube and tube connects needs loaded down with trivial details operation just can complete, and must carry pipe at every turn and connect, when operatively far away with warehouse, no matter less one or several pipes connect and also must go to warehouse to reach, or multi-band is several makes provision against emergencies, and has so virtually increased labor intensity.
Summary of the invention
The purpose of this utility model is to provide a kind of by tube end being increased to flange corresponding to convex-concave, and set up one can be by convex-concave flange screwing mechanism, the pipeline that changes up soon lock is opened flange connecting apparatus soon.
One end of a pipe of the utility model is with recessed flange, one end of No. two pipes is with boss flange, the boss of boss flange mates with the groove of recessed flange, there is the upper cover of a pipe of recessed flange to screw nut, screwing nut one end is stuck on recessed flange, the other end is with internal thread, and the internal thread that screws nut mates with the outside thread on boss flange sidewall.
The utility model has the hole that spins screwing on nut.
The utility model is simple in structure, easy to install, and in the time of need to connecting, as long as two pipes corresponding to convex-concave are aimed at, then turn screws nut, two tube ends can be tightened together firmly.If need dismounting, be also simple counterrotating screw nut can so that two pipes separate easily.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model Fig. 1 concave flange arrangement schematic diagram;
Fig. 3 is the utility model Fig. 1 convexity flange arrangement schematic diagram.
Embodiment
One end of a pipe 1 of the utility model is with recessed flange 2, one end of No. two pipes 5 is with boss flange 4, the boss 41 of boss flange 4 mates with the groove 21 of recessed flange 2, there is the cover on 1 of managing for No. of recessed flange 2 to screw nut 3, screwing nut 3 one end is stuck on recessed flange 2, the other end is with internal thread, and the internal thread that screws nut 3 mates with the outside thread 42 on boss flange 4 sidewalls.
During use, the recessed flange of a pipe is aimed at the boss flange of another pipe, then the boss of boss flange is inserted in the groove of recessed flange, after aligning, turn screws nut, thereby makes convex-concave flange closely, be firmly close together, thereby completes linking.If because personal factor exists, may there is the sealing problem of connected portion, so can increase a rubber pad between two pipes.Reversion turn nut can be easily by two pipes separately.
The utility model has the hole 6 that spins screwing on nut 3.If screw the structure that nut 3 adopts hex head bolt, may just need professional spanner, in order to save the use of Wrench, so open the hole 6 that spins on nut 3 screwing, this hole that spins only needs to insert a reinforcing bar that relatively has intensity, iron etc. can complete the rotation that screws nut 3.
